A 'Philosophy' of Plastic Surgery in Brazil - NYTimes.com - 0 views

  • Is beauty a right, which, like education or health care, should be realized with the help of public institutions and expertise?
  • For years he has performed charity surgeries for the poor. More radically, some of his students offer free cosmetic operations in the nation’s public health system.
  • I asked her why she wanted to have the surgery.  “I didn’t put in an implant to exhibit myself, but to feel better. It wasn’t a simple vanity, but a  . . . necessary vanity.  Surgery improves a woman’s auto-estima.”
  • ...11 more annotations...
  • He argues that the real object of healing is not the body, but the mind.  A plastic surgeon is a “psychologist with a scalpel in his hand.” This idea led Pitanguy to argue for the “union” of cosmetic and reconstructive procedures.  In both types of surgery beauty and mental healing subtly mingle, he claims, and both benefit health.
  • “What is the difference between a plastic surgeon and a psychoanalyst?  The psychoanalyst knows everything but changes nothing.  The plastic surgeon knows nothing but changes everything.”
  • Plastic surgery gained legitimacy in the early 20th century by limiting itself to reconstructive operations.  The “beauty doctor” was a term of derision.  But as techniques improved they were used for cosmetic improvements.  Missing, however, was a valid diagnosis. Concepts like psychoanalyst Alfred Adler’s inferiority complex — and later low self-esteem — provided a missing link.
  • Victorians saw a cleft palate as a defect that built character. For us it hinders self-realization and merits corrective surgery.  This shift reflects a new attitude towards appearance and mental health: the notion that at least some defects cause unfair suffering and social stigma is now widely accepted. But Brazilian surgeons take this reasoning a step further.  Cosmetic surgery is a consumer service in most of the world.  In Brazil it is becoming, as Ester put it, a “necessary vanity.”
  • Pitanguy, whose patients often have mixed African, indigenous and European ancestry, stresses that aesthetic ideals vary by epoch and ethnicity.  What matters are not objective notions of beauty, but how the patient feels.  As his colleague says, the job of the plastic surgeon is to simply “follow desires.”
  • Patients are on average younger than they were 20 years ago.  They often request minor changes to become, as one surgeon said, “more perfect.”
  • The growth of plastic surgery thus reflects a new way of working not only on the suffering mind, but also on the erotic body.  Unlike fashion’s embrace of playful dissimulation and seduction, this beauty practice instead insists on correcting precisely measured flaws.  Plastic surgery may contribute to a biologized view of sex where pleasure and fantasy matter less than the anatomical “truth” of the bare body.
  • It is not coincidental that Brazil has not only high rates of plastic surgery, but also Cesarean sections (70 percent of deliveries in some private hospitals), tubal ligations,  and other surgeries for women. Some women see elective surgeries as part of a modern standard of care, more or less routine for the middle class, but only sporadically available to the poor.
  • When a good life is defined through the ability to buy goods then rights may be reinterpreted to mean not equality before the law, but equality in the market. 
  • Beauty is unfair: the attractive enjoy privileges and powers gained without merit.  As such it can offend egalitarian values.  Yet while attractiveness is a quality “awarded” to those who don’t morally deserve it, it can also grant power to those excluded from other systems of privilege.  It is a kind of “double negative”: a form of power that is unfairly distributed but which can disturb other unfair hierarchies.  For this reason it may have democratic appeal.  In poor urban areas beauty often has a similar importance for girls as soccer (or basketball) does for boys: it promises an almost magical attainment of recognition, wealth or power.
  • For many consumers attractiveness is essential to economic and sexual competition, social visibility, and mental well being.  This “value” of appearance may be especially clear for those excluded from other means of social ascent.  For the poor beauty is often a form of capital that can be exchanged for other benefits, however small, transient, or unconducive to collective change.

Recycling News: China to Ban Single-Use Plastic in Cities - Bloomberg - 0 views

  • China’s top economic planner said it would cut the production and use of plastic over the next five years, helping reduce one of the world’s biggest sources of plastic pollution.By the end of this year, non-degradable plastic bags will be banned in places such as supermarkets and shopping malls in major cities, as well as in the country’s ubiquitous food delivery services, according to a plan released by the National Development and Reform Commission on Sunday.
  • China will significantly reduce the use of disposable plastic in e-commerce, express deliveries and takeaway food by 2022, while promoting alternative materials,
  • The use of plastic in the world’s most populous nation has risen as online shopping and food delivery apps have become part of everyday life, even in rural areas.

Plastic waste is booming from the coronavirus pandemic - CNN - 0 views

  • Surgical masks, gloves, protective equipment, body bags -- the Covid-19 crisis has spurred a rapid expansion in the production of desperately-needed plastic products, with governments racing to boost their stockpiles and regular citizens clamoring for their share of supplies.
  • But all that plastic ends up somewhere -- and environmental campaigners fear it is just the tip of a looming iceberg, with the pandemic causing a number of serious challenges to their efforts to reduce plastic pollution.
  • "Right outside my house there are discarded gloves and masks all over the neighborhood," says John Hocevar, oceans campaign director at Greenpeace USA.
  • ...5 more annotations...
  • "We know that plastic pollution is a global problem -- it existed before the pandemic," Nick Mallos of US-based NGO Ocean Conservancy tells CNN. "(But) we've seen a lot of industry efforts to roll back some of the great progress that's been made.
  • "It's been raining here for two days, so these are very quickly washed down into the sewer. Here in Washington DC, they end up in the Anacostia River, out in the Chesapeake Bay, and then the Atlantic Ocean."
  • Over time, those products break down and add to the vast collections of microplastics in our seas, air and food. And the irony is that, while we produce and discard plastic to fight one public health crisis, we may be slowly contributing to another.
  • "As Covid-19 hits, it seems to be shifting the tide toward single-use plastics," Peszko concluded.
  • "We are oversaturated daily with news around the pandemic ... there is so much information streaming to us daily that many of these types of messages can be missed," he says. "It may not seem like a significant action at the moment, but it will manifest in very dangerous ways down the road."

Was There a Civilization On Earth Before Humans? - The Atlantic - 0 views

  • When it comes to direct evidence of an industrial civilization—things like cities, factories, and roads—the geologic record doesn’t go back past what’s called the Quaternary period 2.6 million years ago
  • if we’re going back this far, we’re not talking about human civilizations anymore. Homo sapiens didn’t make their appearance on the planet until just 300,000 years or so ago. That means the question shifts to other species, which is why Gavin called the idea the Silurian hypothesis
  • could researchers find clear evidence that an ancient species built a relatively short-lived industrial civilization long before our own? Perhaps, for example, some early mammal rose briefly to civilization building during the Paleocene epoch about 60 million years ago. There are fossils, of course. But the fraction of life that gets fossilized is always minuscule and varies a lot depending on time and habitat. It would be easy, therefore, to miss an industrial civilization that only lasted 100,000 years—which would be 500 times longer than our industrial civilization has made it so far.
  • ...11 more annotations...
  • Given that all direct evidence would be long gone after many millions of years, what kinds of evidence might then still exist? The best way to answer this question is to figure out what evidence we’d leave behind if human civilization collapsed at its current stage of development.
  • Now that our industrial civilization has truly gone global, humanity’s collective activity is laying down a variety of traces that will be detectable by scientists 100 million years in the future. The extensive use of fertilizer, for example
  • And then there’s all that plastic. Studies have shown increasing amounts of plastic “marine litter” are being deposited on the seafloor everywhere from coastal areas to deep basins and even in the Arctic. Wind, sun, and waves grind down large-scale plastic artifacts, leaving the seas full of microscopic plastic particles that will eventually rain down on the ocean floor, creating a layer that could persist for geological timescales.
  • Likewise our relentless hunger for the rare-Earth elements used in electronic gizmos. Far more of these atoms are now wandering around the planet’s surface because of us than would otherwise be the case. They might also show up in future sediments, too.
  • Once you realize, through climate change, the need to find lower-impact energy sources, the less impact you will leave. So the more sustainable your civilization becomes, the smaller the signal you’ll leave for future generations.
  • The more fossil fuels we burn, the more the balance of these carbon isotopes shifts. Atmospheric scientists call this shift the Suess effect, and the change in isotopic ratios of carbon due to fossil-fuel use is easy to see over the last century. Increases in temperature also leave isotopic signals. These shifts should be apparent to any future scientist who chemically analyzes exposed layers of rock from our era. Along with these spikes, this Anthropocene layer might also hold brief peaks in nitrogen, plastic nanoparticles, and even synthetic steroids
  • Fifty-six million years ago, Earth passed through the Paleocene-Eocene Thermal Maximum (PETM). During the PETM, the planet’s average temperature climbed as high as 15 degrees Fahrenheit above what we experience today. It was a world almost without ice, as typical summer temperatures at the poles reached close to a balmy 70 degrees Fahrenheit.
  • While there is evidence that the PETM may have been driven by a massive release of buried fossil carbon into the air, it’s the timescale of these changes that matter. The PETM’s isotope spikes rise and fall over a few hundred thousand years. But what makes the Anthropocene so remarkable in terms of Earth’s history is the speed at which we’re dumping fossil carbon into the atmosphere. There have been geological periods where Earth’s CO2 has been as high or higher than today, but never before in the planet’s multibillion-year history has so much buried carbon been dumped back into the atmosphere so quickly
  • So the isotopic spikes we do see in the geologic record may not be spiky enough to fit the Silurian hypothesis’s bill.
  • ronically, however, the most promising marker of humanity’s presence as an advanced civilization is a by-product of one activity that may threaten it most.
  • “How do you know we’re the only time there’s been a civilization on our own planet?”

Researchers Propose Earth's 'Anthropocene' Age of Humans Began With Fallout and Plastic... - 0 views

  • we’ve left the Holocene behind — that’s the geological epoch since the end of the last ice age — and entered “a post-Holocene…geological age of our own making,” now best known as the Anthropocene.
  • the Anthropocene Working Group (because of my early writings, I’m a lay member), has moved substantially from asking whether such a transition has occurred to deciding when.

  • Once you begin to get the many feedbacks bouncing off each other and bouncing off the Earth system, it’s going to be very hard to follow what’s going to happen, particularly biologically…. One could not imagine, at the very end of the Cretaceous, the beginning of the Tertiary, that the mammals — these itty-bitty little squeaky furry things, would take over – effectively taking the position that the dinosaurs held for so long. All we can say is that, for sure, it will be different. We’re going down a different trouser leg of history.
  • on whether it’s possible to have a “good Anthropocene.” Kolbert’s Twitter post last spring nicely captured their view:
  • Taking full ownership of the Anthropocene won’t be easy. The necessary feeling is a queasy mix of excitement and unease. I’ve compared it to waking up in the first car on the first run of a new roller coaster that hasn’t been examined fully by engineers.
  • That’s a very different sensation than, say, mourning the end of nature. It’s more a celebration, in a way — a deeper acceptance of our place on the planet, with all of our synthetic trappings, and our faults, as fundamentally natural.
  • There’s little predictability in how things will play out after this anthropogenic jolt, especially in the living world. [More on the “great acceleration” behind the jolt is here.]
  • “The way I would like to see it is in, say, 100 years in the future the London Geological Society will look back and consider this period…a transition from the lesser Anthropocene to the greater Anthropocene.”
  • Fully integrating this awareness into our personal choices and societal norms and policies will take time. It is “the great work,” as Thomas Berry put it.
  • Technology alone will not do the trick. Another keystone to better meshing humanity’s infinite aspirations with life on a finite planet will be slowly shifting value systems from the foundation up
  • Edward O. Wilson’s “Biophilia” was a powerful look outward at the characteristics of the natural world that we inherently cherish.
  • Now we need a dose of what I’ve taken to calling anthropophilia, as well.
  • We have to accept ourselves, flaws and all, in order to move beyond what has been something of an unconscious, species-scale pubescent growth spurt, enabled by fossil fuels in place of testosterone.
  • We’re stuck with “The World With Us.” It’s time to grasp that uncomfortable, but ultimately hopeful, idea.

Maturation of the adolescent brain - 1 views

  • The adolescent population is highly vulnerable to driving under the influence of alcohol and social maladjustments due to an immature limbic system and prefrontal cortex.
  • Synaptic plasticity and the release of neurotransmitters may also be influenced by environmental neurotoxins and drugs of abuse including cigarettes, caffeine, and alcohol during adolescence.
  • Brain maturation during adolescence (ages 10–24 years) could be governed by several factors, as illustrated in Figure 1. It may be influenced by heredity and environment, prenatal and postnatal insult, nutritional status, sleep patterns, pharmacotherapy, and surgical interventions during early childhood.

  • During adolescence, the neurocircuitry strengthens and allows for multitasking, enhanced ability to solve problems, and the capability to process complex information. Furthermore, adolescent brain plasticity provides an opportunity to develop talents and lifelong interests; however, neurotoxic insult, trauma, chronic stress, drug abuse, and sedentary lifestyles may have a negative impact during this sensitive period of brain maturation

Pregnancy Changes the Brain in Ways That May Help Mothering - The New York Times - 0 views

  • Pregnancy changes a woman’s brain, altering the size and structure of areas involved in perceiving the feelings and perspectives of others, according to a first-of-its-kind study published Monday.
  • The results were remarkable: loss of gray matter in several brain areas involved in a process called social cognition or “theory of mind,” the ability to register and consider how other people perceive things.
  • A third possibility is that the loss is “part of the brain’s program for dealing with the future,” he said. Hormone surges in pregnancy might cause “pruning or cellular adaptation that is helpful,” he said, streamlining certain brain areas to be more efficient at mothering skills “from nurturing to extra vigilance to teaching.”
  • ...4 more annotations...
  • Pregnancy, she explained, may help a woman’s brain specialize in “a mother’s ability to recognize the needs of her infant, to recognize social threats or to promote mother-infant bonding.”
  • Researchers wanted to see if the women’s brain changes affected anything related to mothering. They found that relevant brain regions in mothers showed more activity when women looked at photos of their own babies than with photos of other children.
  • During another period of roiling hormonal change — adolescence — gray matter decreases in several brain regions that are believed to provide fine-tuning for the social, emotional and cognitive territory of being a teenager.
  • evidence against the common myth of ‘mommy brain.’
  •  
    Our brain changes during our lifetime to better fit our need. The decrease in gray matter in brain during pregnancy enables mothers to learn mothering skills fasters and be more focused on their own child. This aligns with the logic of evolution because newborns need a lot of attention and care from their mother. I am also very surprised to see that the similar thing also happens to teenager. The decrease in gray matter gives plasticity for teenagers to absorb new knowledge. It's so amazing that our brain is actually adjusting itself in different stages of life. --Sissi (12/20/2016)

Mannequins Give Shape to a Venezuelan Fantasy - NYTimes.com - 0 views

  • Eliezer Álvarez made a simple observation: Venezuelan women were increasingly using plastic surgery to transform their bodies, yet the mannequins in clothing stores did not reflect these new, often extreme proportions.
  • So he went back to his workshop and created the kind of woman he thought the public wanted — one with a bulging bosom and cantilevered buttocks, a wasp waist and long legs, a fiberglass fantasy, Venezuelan style
  • Now his mannequins, and others like them, have become the standard in stores across Venezuela, serving as an exaggerated, sometimes polarizing, vision of the female form that calls out from the doorways of tiny shops

  • “You see a woman like this and you say, ‘Wow, I want to look like her,’ ” said Reina Parada, as she sanded a mannequin torso in the workshop. Although she cannot afford it, she said, she would like to get implant surgery someday. “It gives you better self-esteem.”
  • Cosmetic procedures are so fashionable here that a woman with implants is often casually referred to as “an operated woman.” Women freely talk about their surgeries, and mannequin makers jokingly refer to the creations as being “operated” as well.
  • The embrace of plastic surgery clashes with the government’s socialist ideology and frequent talk of creating a society free of the taint of commercialism.
  • the world’s largest estimated petroleum reserves — has long fed a culture of easy money and consumerism here, along with a penchant for the quick fix and instant gratification.

  • Beauty took on a particularly important role in the late 1970s and ’80s when the country’s beauty queens, already a national obsession, were crowned Miss Universe three times.
  • And the beauty queens’ fame helped fuel a fascination with cosmetic surgery and procedures like breast implants, tummy tucks, nose jobs and injections to firm the buttocks.

What Cookies and Meth Have in Common - The New York Times - 0 views

  • Why would anyone continue to use recreational drugs despite the medical consequences and social condemnation? What makes someone eat more and more in the face of poor health?
  • modern humans have designed the perfect environment to create both of these addictions.
  • the myth has persisted that addiction is either a moral failure or a hard-wired behavior — that addicts are either completely in command or literally out of their minds
  • ...17 more annotations...
  • Now we have a body of research that makes the connection between stress and addiction definitive. More surprising, it shows that we can change the path to addiction by changing our environment.
  • Neuroscientists have found that food and recreational drugs have a common target in the “reward circuit” of the brain, and that the brains of humans and other animals who are stressed undergo biological changes that can make them more susceptible to addiction.
  • In a 2010 study, Diana Martinez and colleagues at Columbia scanned the brains of a group of healthy controls and found that lower social status and a lower degree of perceived social support — both presumed to be proxies for stress — were correlated with fewer dopamine receptors, called D2s, in the brain’s reward circuit
  • The reward circuit evolved to help us survive by driving us to locate food or sex in our environment
  • Today, the more D2 receptors you have, the higher your natural level of stimulation and pleasure — and the less likely you are to seek out recreational drugs or comfort food to compensate
  • people addicted to cocaine, heroin, alcohol and methamphetamines experience a significant reduction in their D2 receptor levels that persists long after drug use has stopped. These people are far less sensitive to rewards, are less motivated and may find the world dull, once again making them prone to seek a chemical means to enhance their everyday life.
  • Drug exposure also contributes to a loss of self-control. Dr. Volkow found that low D2 was linked with lower activity in the prefrontal cortex, which would impair one’s ability to think critically and exercise restraint
  • Food, like drugs, stimulates the brain’s reward circuit. Chronic exposure to high-fat and sugary foods is similarly linked with lower D2 levels, and people with lower D2 levels are also more likely to crave such foods. It’s a vicious cycle in which more exposure begets more craving.
  • At this point you may be wondering: What controls the reward circuit in the first place? Some of it is genetic. We know that certain gene variations elevate the risk of addiction to various drugs. But studies of monkeys suggest that our environment can trump genetics and rewire the brain.
  • simply by changing the environment, you can increase or decrease the likelihood of an animal becoming a drug addict.
  • The same appears true for humans. Even people who are not hard-wired for addiction can be made dependent on drugs if they are stressed
  • Is it any wonder, then, that the economically frightening situation that so many Americans experience could make them into addicts? You will literally have a different brain depending on your ZIP code, social circumstances and stress level.
  • In 1990, no state in our country had an adult obesity rate above 15 percent; by 2015, 44 states had obesity rates of 25 percent or higher. What changed?
  • What happened is that cheap, calorie-dense foods that are highly rewarding to your brain are now ubiquitous.
  • Nothing in our evolution has prepared us for the double whammy of caloric modern food and potent recreational drugs. Their power to activate our reward circuit, rewire our brain and nudge us in the direction of compulsive consumption is unprecedented.
  • The processed food industry has transformed our food into a quasi-drug, while the drug industry has synthesized ever more powerful drugs that have been diverted for recreational use.
  • Fortunately, our brains are remarkably plastic and sensitive to experience. Although it’s far easier said than done, just limiting exposure to high-calorie foods and recreational drugs would naturally reset our brains to find pleasure in healthier foods and life without drugs.

Full article: Functionalism and the role of psychology in economics - 0 views

  • Should economics study the psychological basis of agents’ choice behaviour? I show how this question is multifaceted and profoundly ambiguous. There is no sharp distinction between ‘mentalist’ answers to this question and rival ‘behavioural’ answers. What's more, clarifying this point raises problems for mentalists of the ‘functionalist’ variety [Dietrich, F., & List, C. (2016). Mentalism versus behaviourism in economics: A philosophy-of-science perspective. Economics and Philosophy, 32(2), 249–281. https://doi.org/10.1017/S0266267115000462]. Firstly, functionalist hypotheses collapse into hypotheses about input–output dispositions, I show, unless one places some unwelcome restrictions on what counts as a cognitive variable. Secondly, functionalist hypotheses make some risky commitments about the plasticity of agents’ choice dispositions.
  • This controversy over the proper role of psychological concepts, explanations and evidence in economics is multifaceted and profoundly indeterminate, this paper will argue. In what way multifaceted? One facet of this controversy is the issue of whether economics should study the anatomical structures in the brain that underlie decision-making (Section 3). A second facet is the issue of whether economics should study the causes and effects of cognitive variables (Section 4). A third facet, I suggest, is the issue of whether economics should study the plasticity of agents’ choice dispositions (Section 6).

Meet the neuroscientist shattering the myth of the gendered brain | Science | The Guardian - 0 views

  • since the 18th century “when people were happy to spout off about what men and women’s brains were like – before you could even look at them. They came up with these nice ideas and metaphors that fitted the status quo and society, and gave rise to different education for men and women.”
  • she couldn’t find any beyond the negligible, and other research was also starting to question the very existence of such differences. For example, once any differences in brain size were accounted for, “well-known” sex differences in key structures disappeared.
  • Are there any significant differences based on sex alone? The answer, she says, is no.
  • “The idea of the male brain and the female brain suggests that each is a characteristically homogenous thing and that whoever has got a male brain, say, will have the same kind of aptitudes, preferences and personalities as everyone else with that ‘type’ of brain. We now know that is not the case.
  • ‘Forget the male and female brain; it’s a distraction, it’s inaccurate.’ It’s possibly harmful, too, because it’s used as a hook to say, well, there’s no point girls doing science because they haven’t got a science brain, or boys shouldn’t be emotional or should want to lead.”
  • The next question was, what then is driving the differences in behaviour between girls and boys, men and women?
  • “that the brain is moulded from birth onwards and continues to be moulded through to the ‘cognitive cliff’ in old age when our grey cells start disappearing.

  • The rules will change how the brain works and how someone behaves.” The upshot of gendered rules? “The ‘gender gap’ becomes a self-fulfilling prophecy.”
  • The brain is a biological organ. Sex is a biological factor. But it is not the sole factor; it intersects with so many variables.”
  • Letting go of age-old certainties is frightening, concedes Rippon, who is both optimistic about the future, and fearful for it.
  • On the plus side, our plastic brains are good learners. All we need to do is change the life lessons.
  • One major breakthrough in recent years has been the realisation that, even in adulthood, our brains are continually being changed, not just by the education we receive, but also by the jobs we do, the hobbies we have, the sports we play.
  • Once we acknowledge that our brains are plastic and mouldable, then the power of gender stereotypes becomes evident.
  • Beliefs about sex differences (even if ill-founded) inform stereotypes, which commonly provide just two labels – girl or boy, female or male – which, in turn, historically carry with them huge amounts of “contents assured” information and save us having to judge each individual on their own merits
  • With input from exciting breakthroughs in neuroscience, the neat, binary distinctiveness of these labels is being challenged – we are coming to realise that nature is inextricably entangled with nurture.
  • The 21st century is not just challenging the old answers – it is challenging the question itself.

Phantom limb pain: A literature review - 0 views

  • . The purpose of this review article is to summarize recent researches focusing on phantom limb in order to discuss its definition, mechanisms, and treatments.
  • The incidence of phantom limb pain has varied from 2% in earlier records to higher rates today. Initially, patients were less likely to mention pain symptoms than today which is a potential explanation for the discrepancy in incidence rates. However, Sherman et al.4 discuss that only 17% phantom limb complaints were initiated treated by physicians. Consequently, it is important to determine what constitutes phantom pain in order to provide efficacious care. Phantom pain is pain sensation to a limb, organ or other tissue after amputation and/or nerve injury.5 In podiatry, the predominant cause of phantom limb pain is after limb amputation due to diseased state presenting with an unsalvageable limb. Postoperative pain sensations from stump neuroma pain, prosthesis, fibrosis, and residual local tissue inflammation can be similar to phantom limb pain (PLP). Patients with PLP complain of various sensations including burning, stinging, aching, and piercing pain with changing warmth and cold sensation to the amputated area which waxes and wanes.6 Onset of symptoms may be elicited by environmental, emotional, or physical changes.
  • The human body encompasses various neurologic mechanisms allowing reception, transport, recognition, and response to numerous stimuli. Pain, temperature, crude touch, and pressure sensory information are carried to the central nervous system via the anterolateral system, with pain & temperature information transfer via lateral spinothalamic tracts to the parietal lobe. In detail, pain sensation from the lower extremity is transported from a peripheral receptor to a first degree pseudounipolar neurons in the dorsal root ganglion and decussate and ascend to the third-degree neurons within the thalamus.7 This sensory information will finally arrive at the primary sensory cortex in the postcentral gyrus of the parietal lobe which houses the sensory homunculus.8 It is unsurprising that with an amputation that such an intricate highway of information transport to and from the periphery may have the potential for problematic neurologic developments.

  • How does pain sensation, a protection mechanism for the human body, become chronic and unrelenting after limb loss? This is a question researchers still ask today with no concise conclusion. Phantom limb pain occurs more frequently in patients who also experience longer periods of stump pain and is more likely to subside as the stump pain subsides.9 Researchers have also found dorsal root ganglion cells change after a nerve is completely cut. The dorsal root ganglion cells become more active and sensitive to chemical and mechanical changes with potential for plasticity development at the dorsal horn and other areas.10 At the molecular level, increasing glutamate and NMDA (N-methyl d-aspartate) concentrations correlate to increased sensitivity which contributes to allodynia and hyperalgesia.11 Flor et al.12 further described the significance of maladaptive plasticity and the development of memory for pain and phantom limb pain. They correlated it to the loss of GABAergic inhibition and the development of glutamate induced long-term potentiation changes and structural changes like myelination and axonal sprouting.
  • Phantom limb pain in some patients may gradually disappear over the course of a few months to one year if not treated, but some patients suffer from phantom limb pain for decades. Treatments include pharmacotherapy, adjuvant therapy, and surgical intervention. There are a variety of medications to choose from, which includes tricyclic antidepressants, opioids, and NSAIDs, etc. Among these medications, Tricyclic antidepressant is one of the most common treatments. Studies have shown that Amitriptyline (a tricyclic antidepressant) has a good effect on relieving neuropathic pain.25
  • Phantom limb pain is very common in amputees. As a worldwide issue, it has been studied by a lot of researchers. Although phantom limb sensation has already been described and proposed by French military surgeon Ambroise Pare 500 years ago, there is still no detailed explanation of its mechanisms. Therefore, more research will be needed on the different types of mechanisms of phantom limb pain. Once researchers and physicians are able to identify the mechanism of phantom limb pain, mechanism-based treatment will be rapidly developed. As a result, more patients will be benefit from it in the long run.

DeepMind uncovers structure of 200m proteins in scientific leap forward | DeepMind | Th... - 0 views

  • Proteins are the building blocks of life. Formed of chains of amino acids, folded up into complex shapes, their 3D structure largely determines their function. Once you know how a protein folds up, you can start to understand how it works, and how to change its behaviour
  • Although DNA provides the instructions for making the chain of amino acids, predicting how they interact to form a 3D shape was more tricky and, until recently, scientists had only deciphered a fraction of the 200m or so proteins known to science

  • In November 2020, the AI group DeepMind announced it had developed a program called AlphaFold that could rapidly predict this information using an algorithm. Since then, it has been crunching through the genetic codes of every organism that has had its genome sequenced, and predicting the structures of the hundreds of millions of proteins they collectively contain.
  • Last year, DeepMind published the protein structures for 20 species – including nearly all 20,000 proteins expressed by humans – on an open database. Now it has finished the job, and released predicted structures for more than 200m proteins.
  • “Essentially, you can think of it as covering the entire protein universe. It includes predictive structures for plants, bacteria, animals, and many other organisms, opening up huge new opportunities for AlphaFold to have an impact on important issues, such as sustainability, food insecurity, and neglected diseases,”
  • In May, researchers led by Prof Matthew Higgins at the University of Oxford announced they had used AlphaFold’s models to help determine the structure of a key malaria parasite protein, and work out where antibodies that could block transmission of the parasite were likely to bind.
  • “Previously, we’d been using a technique called protein crystallography to work out what this molecule looks like, but because it’s quite dynamic and moves around, we just couldn’t get to grips with it,” Higgins said. “When we took the AlphaFold models and combined them with this experimental evidence, suddenly it all made sense. This insight will now be used to design improved vaccines which induce the most potent transmission-blocking antibodies.”
  • AlphaFold’s models are also being used by scientists at the University of Portsmouth’s Centre for Enzyme Innovation, to identify enzymes from the natural world that could be tweaked to digest and recycle plastics. “It took us quite a long time to go through this massive database of structures, but opened this whole array of new three-dimensional shapes we’d never seen before that could actually break down plastics,” said Prof John McGeehan, who is leading the work. “There’s a complete paradigm shift. We can really accelerate where we go from here
  • “AlphaFold protein structure predictions are already being used in a myriad of ways. I expect that this latest update will trigger an avalanche of new and exciting discoveries in the months and years ahead, and this is all thanks to the fact that the data are available openly for all to use.”

The Class Politics of Instagram Face - Tablet Magazine - 0 views

  • by approaching universality, Instagram Face actually secured its role as an instrument of class distinction—a mark of a certain kind of woman. The women who don’t mind looking like others, or the conspicuousness of the work they’ve had done
  • Instagram Face goes with implants, middle-aged dates and nails too long to pick up the check. Batting false eyelashes, there in the restaurant it orders for dinner all the food groups of nouveau riche Dubai: caviar, truffle, fillers, foie gras, Botox, bottle service, bodycon silhouettes. The look, in that restaurant and everywhere, has reached a definite status. It’s the girlfriend, not the wife.
  • Does cosmetic work have a particular class? It has a price tag, which can amount to the same thing, unless that price drops low enough.

  • Before the introduction of Botox and hyaluronic acid dermal fillers in 2002 and 2003, respectively, aesthetic work was serious, expensive. Nose jobs and face lifts required general anesthesia, not insignificant recovery time, and cost thousands of dollars (in 2000, a facelift was $5,416 on average, and a rhinoplasty $4,109, around $9,400 and $7,000 adjusted).
  • In contrast, the average price of a syringe of hyaluronic acid filler today is $684, while treating, for example, the forehead and eyes with Botox will put you out anywhere from $300 to $600
  • We copied the beautiful and the rich, not in facsimile, but in homage.
  • In 2018, use of Botox and fillers was up 18% and 20% from five years prior. Philosophies of prejuvenation have made Botox use jump 22% among 22- to 37-year-olds in half a decade as well. By 2030, global noninvasive aesthetic treatments are predicted to triple.
  • The trouble is that a status symbol, without status, is common.
  • Beauty has always been exclusive. When someone strikes you as pretty, it means they are something that everyone else is not.
  • It’s a zero-sum game, as relative as our morals. Naturally, we hoard of beauty what we can. It’s why we call grooming tips “secrets.”
  • Largely the secrets started with the wealthy, who possess the requisite money and leisure to spare on their appearances
  • Botox and filler only accelerated a trend that began in the ’70s and ’80s and is just now reaching its saturation point.
  • we didn’t have the tools for anything more than emulation. Fake breasts and overdrawn lips only approximated real ones; a birthmark drawn with pencil would always be just that.
  • Instagram Face, on the other hand, distinguishes itself by its sheer reproducibility. Not only because of those new cosmetic technologies, which can truly reshape features, at reasonable cost and with little risk.
  • built in to the whole premise of reversible, low-stakes modification is an indefinite flux, and thus a lack of discretion.
  • Instagram Face has replicated outward, with trendsetters giving up competing with one another in favor of looking eerily alike. And obviously it has replicated down.
  • Eva looks like Eva. If she has procedures in common with Kim K, you couldn’t tell. “I look at my features and I think long and hard of how I can, without looking different and while keeping as natural as possible, make them look better and more proportional. I’m against everything that is too invasive. My problem with Instagram Face is that if you want to look like someone else, you should be in therapy.”
  • natural looks have always been, and still are, more valuable than artificial ones. Partly because of our urge to legitimize in any way we can the advantages we have over other people. Hotness is a class struggle.
  • As more and more women post videos of themselves eating, sleeping, dressing, dancing, and Only-Fanning online, in a logical bid for economic ascendance, the women who haven’t needed to do that gain a new status symbol.
  • Privacy. A life which is not a ticketed show. An intimacy that does not admit advertisers. A face that does not broadcast its insecurity, or the work undergone to correct it.
  • Upper class, private women get discrete work done. The differences aren’t in the procedures themselves—they’re the same—but in disposition
  • Eva, who lives between central London, Geneva, and the south of France, says: “I do stuff, but none of the stuff I do is at all in my head associated with Instagram Face. Essentially you do similar procedures, but the end goal is completely different. Because they are trying to get the result of looking like another human being, and I’m just beautifying myself.”
  • But the more rapidly it replicates, and the clearer our manuals for quick imitation become, the closer we get to singularity—that moment Kim Kardashian fears unlike any other: the moment when it becomes unclear whether we’re copying her, or whether she is copying us.
  • what he restores is complicated and yet not complicated at all. It’s herself, the fingerprint of her features. Her aura, her presence and genealogy, her authenticity in space and time.
  • Dr. Taktouk’s approach is “not so formulaic.” He aims to give his patients the “better versions of themselves.” “It’s not about trying to be anyone else,” he says, “or creating a conveyor belt of patients. It’s about working with your best features, enhancing them, but still looking like you.”
  • “Vulgar” says that in pursuing indistinguishability, women have been duped into another punishing divide. “Vulgar” says that the subtlety of his work is what signals its special class—and that the women who’ve obtained Instagram Face for mobility’s sake have unwittingly shut themselves out of it.
  • While younger women are dissolving their gratuitous work, the 64-year-old Madonna appeared at the Grammy Awards in early February, looking so tragically unlike herself that the internet launched an immediate postmortem.
  • The folly of Instagram Face is that in pursuing a bionic ideal, it turns cosmetic technology away from not just the reality of class and power, but also the great, poignant, painful human project of trying to reverse time. It misses the point of what we find beautiful: that which is ephemeral, and can’t be reproduced
  • Age is just one of the hierarchies Instagram Face can’t topple, in the history of women striving versus the women already arrived. What exactly have they arrived at?
  • Youth, temporarily. Wealth. Emotional security. Privacy. Personal choices, like cosmetic decisions, which are not so public, and do not have to be defended as empowered, in the defeatist humiliation of our times
  • Maybe they’ve arrived at love, which for women has never been separate from the things I’ve already mentioned.
  • I can’t help but recall the time I was chatting with a plastic surgeon. I began to point to my features, my flaws. I asked her, “What would you do to me, if I were your patient?” I had many ideas. She gazed at me, and then noticed my ring. “Nothing,” she said. “You’re already married.”

The Way to Produce a Person - NYTimes.com - 0 views

  • the brain is a malleable organ. Every time you do an activity, or have a thought, you are changing a piece of yourself into something slightly different than it was before. Every hour you spend with others, you become more like the people around you.
  • Gradually, you become a different person. If there is a large gap between your daily conduct and your core commitment, you will become more like your daily activities and less attached to your original commitment. You will become more hedge fund, less malaria.
  • I would worry about turning yourself into a means rather than an end. If you go to Wall Street mostly to make money for charity, you may turn yourself into a machine for the redistribution of wealth. You may turn yourself into a fiscal policy.

  • a human life is not just a means to produce outcomes, it is an end in itself. When we evaluate our friends, we don’t just measure the consequences of their lives. We measure who they intrinsically are. We don’t merely want to know if they have done good. We want to know if they are good.
  • We live in a relentlessly commercial culture, so it’s natural that many people would organize their lives in utilitarian and consequentialist terms. But it’s possible to get carried away with this kind of thinking — to have logic but no wisdom

Erasing History in the Internet Era - NYTimes.com - 1 views

  • Lorraine Martin, a nurse in Greenwich, was arrested in 2010 with her two grown sons when police raided her home and found a small stash of marijuana, scales and plastic bags. The case against her was tossed out when she agreed to take some drug classes, and the official record was automatically purged. It was, the law seemed to assure her, as if it had never happened.
  • Defamation is the publication of information that is both damaging and false. The arrest story was obviously true when it was first published. But Connecticut’s erasure law has already established that truth can be fungible. Martin, her suit says, was “deemed never to have been arrested.” And therefore the news story had metamorphosed into a falsehood.
  • They debate the difference between “historical fact” and “legal fact.” They dispute whether something that was true when it happened can become not just private but actually untrue, so untrue you can swear an oath that it never happened and, in the eyes of the law, you’ll be telling the truth.

  • Google’s latest transparency report shows a sharp rise in requests from governments and courts to take down potentially damaging material.
  • In Europe, where press freedoms are less sacred and the right to privacy is more ensconced, the idea has taken hold that individuals have a “right to be forgotten,” and those who want their online particulars expunged tend to have the government on their side. In Germany or Spain, Lorraine Martin might have a winning case.
  • The Connecticut case is just one manifestation of an anxious backlash against the invasive power of the Internet, a world of Big Data and ever more powerful search engines, in which it seems almost everything is permanently recorded and accessible to almost anyone — potential employers, landlords, dates, predators
  • The Times’s policy is not to censor history, because it’s history. The paper will update an arrest story if presented with evidence of an acquittal or dismissal, completing the story but not deleting the story.
  • Owen Tripp, a co-founder of Reputation.com, which has made a business out of helping clients manage their digital profile, advocated a “right to be forgotten” in a YouTube video. Tripp said everyone is entitled to a bit of space to grow up, to experiment, to make mistakes.
  • “This is not just a privacy problem,” said Viktor Mayer-Schönberger, a professor at the Oxford Internet Institute, and author of “Delete: The Virtue of Forgetting in the Digital Age.” “If we are continually reminded about people’s mistakes, we are not able to judge them for who they are in the present. We need some way to put a speed-brake on the omnipresence of the past.”
  • would like to see search engine companies — the parties that benefit the most financially from amassing our information — offer the kind of reputation-protecting tools that are now available only to those who can afford paid services like those of Reputation.com. Google, he points out, already takes down five million items a week because of claims that they violate copyrights. Why shouldn’t we expect Google to give users an option — and a simple process — to have news stories about them down-ranked or omitted from future search results? Good question. What’s so sacred about a search algorithm, anyway?
