Examples of Antibiotic Sensitivity Testing Methods - 0 views

  •  
    There are several different ways to test antibiotic resistance. The category is Diffusion methods. About 1mil of a solution is used and bacteria growth is observed. The second is Disk diffusion method which uses an agar plate. The antibiotic is placed in a ring outside the bacteria and if the bacteria grows outside of the ring it is resistant to the antibiotic, if it doesn't the antibiotic works. There are other methods such as the E-Test, which involves a plastic strip and varying strengths of an antibiotic; Genotypic Methods, which allows testing for a specific mutation; and other more expensive methods of testing.

Mission Critical:Preventing Anitibiotic Resistant - 0 views

  •  
    Antibiotic Resistance is a real problem plaguing healthcare. To prevent antibiotic from never working, steps need to be taken now. For example, patients should not save medicine for the next time they are sick. Another thing a person can do is not skip doses of medicine. There are also many things doctors and pharmacists can do. They can collaborate to better educate patients and be careful about how medicine is prescribed.

Predicting the Spread of Brain Tumors Using Modern Day Biotechnology - 0 views

  • ISOpure uses a set of tumor expression profiles and a panel of healthy tissue expression profiles to generate a purified cancer profile for each tumor sample, and an estimate of the proportion of RNA originating from cancerous cells
  • samples pre-selected to have a high cancerous cell content using pathological estimates [20-23], thereby introducing variability into expression profiles that cannot be removed by current computational pre-processing methods
  • he challenge of computational purification is to decompose each tumor profile tn (a vector of length G) into its component cancer profile (the vector cn), and normal profile
  • ...2 more annotations...
  • Computational purification of tumor expression profiles by ISOpure improves the accuracy of subsequent prognostic models for lung and prostate cancer by reducing inter-sample variation in the amount and type of gene expression signal in the tumor profile that is due to normal tissue contamination.
  • Our analysis demonstrated approximately 10% improvement in prediction of EPE when using ISOpure cancer profiles compared with the unpurified profiles.
  •  
    Using the ISOpure computational purification tool, scientists and medical professionals can develop a prognosis and treatment plan for a certain cancer patients at a much quicker rate. The tool used in this process can help identify the cancerous tissue located in the organs and provide medical professionals further notice of the proportion of RNA originating from cancer cells allowing them to develop treatment plans ahead of time. ISOpure uses an algorithm which determines the proportion of RNA in the organ(s). The real challenges of developing these treatments is of course extracting a portion of tissue with both a normal profile and a cancer profile to predict the spread of the disease. After this portion of tissue has been extracted the ISOpure modeling can process the data using simple MATLAB software. The success of this computational tool is noted to improve the prediction of extra-prostatic-extension (EPE) by 10% in cancer profiles compared to the unpurified models.

A Brain for Rhythm | The Scientist Magazine® - 0 views

  •  
    Since the 1920s, researchers have recorded rhythmic patterns or electrical impulses in the brain. Now, rhythm is known to have effects on perception, attention, working memory, learning, and language. Gazzaley, a neuroscientist, wants to determine if these rhythms vary between healthy individuals. He is also interested in exploring what roles these rhythms play in various disorders. In one experiment, Gazzaley worked with the drummer, Mickey Hart, by strapping him to an EEG while playing the drums. Hart's brain was shown on screen, live.

Listening to your brain rhythms may improve sleep, memory - CBS News - 0 views

  •  
    With previous research suggesting that the fostering of long term memories happens during sleep (when the brain is in an oscillating rhythm), current research suggests that listening to audio coinciding with that rhythm can increase memory skill. As an experiment, researchers worked with 11 healthy students who were asked to memorize 120 word pairs before going to bed. As a result, on the night that they listened to the rhythm of their brain, they remembered the most words. This study also revealed that synced audio was linked to a longer deep sleep instead of more deep sleep cycles.

Why your brain loves music - Telegraph - 0 views

  •  
    The relationship between music and neuroscience involved many research teams, one coming from the Rotman Research Institute in Canada. For this project, the team arranged a group of 19 volunteers, each given short song excerpts (all familiar with the style). While the participants listened, the brains, being scanned by MRI, highlighted one region: the nucleus accumbens, responsible for the sensation of pleasant surprise. However, this only works when the style is recognized.

Music Therapy for Health and Wellness | Psychology Today - 0 views

  •  
    As a pharmacist, Catherine Ulbricht studied different types of music and its therapeutic effects. There are scientific evidences that support that music influences mood and helps with stress. 5 conditions for which music therapy has good evidence for are autism, dementia, depression, infant development, and sleep quality. However, music shouldn't be listened to at high volumes nor should be a sole treatment for dangerous medical/psychiatric conditions; therefore, safety should be taken into account.

Music: It's in your head, changing your brain - CNN.com - 0 views

  •  
    Music can have extraordinary affects on the human brain. Looking in on "ear worms" (meaning getting a song stuck in your head), research reveals that what's going on is neural circuits getting stuck in a repeating loop, playing the thing repeatedly in the head. It is also found that, in the process of human evolution, the structures that respond to music in the brain were first to evolve than the structures that respond to language. Further research also looked into the brain's response to musical pleasure, and animals' response to beats.

Music decreases perceived pain for kids in pediatric ER - 1 views

  •  
    Being the leader of the research team at the University of Alberta, Lisa Hartling experiments with how music affects levels of pain. The team conducted with 42 children in the pediatric ER: half given music to listen to while getting an IV, the rest given no music. Hartling reports that there were less pain after the procedure for the kids that had listened to music than the kids that had not. She hopes to continue this research, testing with different types of music or other distractions to help lower pain during medical procedures.

The stuff of dreams | Science News for Kids - 0 views

  •  
    Using a computer program, Neuroscientist Kamitani led an experiment to compare the brain's activity during sleep and during wake. This study involved 3 adult males, who were hooked up to a fMRI (used to measure brain activity). Being told to describe the things they saw in their dreams, the 3 adults were also asked to look at those objects in real life. Kamitani's study revealed that the brain responded similarly to objects dreamt about or seen awake.

Wait, Have I Dreamt This Before? How Is That Possible? | Psychology Today - 0 views

  •  
    In a survey carried out by Dr. Brown, an author, 86% of the participants reported having experiences that they recall from past dreams. Anne Cleary, Ph.D. has three reasons as to why a moment might seem like a re-experience of a dream: forgetting the experience leading to the dream, connections made during sleep, and mistaking the source. Strongly believing that dreams don't just come from "nowhere", Cleary admits to having "deja vu" experiences before.

Astrology - Are Horoscopes Accurate? | Suite101 - 0 views

  •  
    Phil Plait, the author of Bad Astronomy, strongly believes that astrology is inaccurate according to 3 things horoscopes assert: force from planets and stars affect humans; force can be tracked; horoscopes predict fortune. Scientists argue, that out of the 4 forces (gravity, electromagnetism, strong, and weak), strong and weak forces have nothing to do with astrology itself, and the objects that exert the most gravitational and electromagnetic forces on the Earth have little influence in astrology. Many other researchers and authors support the idea that astrological predictions are biased and harmful.

The effects of the brain in reproduction - 1 views

  • Properly functioning FSH (Follicle Stimulating Hormone) is needed to ensure fertility
  • Recently, the group of researchers at the University of Muenster (Germany) has analysed genetic variants in both the FSH gene and in the FSH receptor, which affect fertility in both males and females.
  • The group found that a distinct single nucleotide change in the DNA structure of FSHB gene (the FSH molecule has 2 subunits -- FSHB is the B subunit) caused significant effects in the functioning of the hormone in both men and women
  • ...3 more annotations...
  • They found that males with the FSHB variation had significant drops in FSH levels and in testicular volume
  • However, the number of women with the combined variation so far studied was not high enough to draw significant conclusions.
  • We estimate that around 45% of infertile men would respond to FSH therapy
  •  
    Reproduction is obviously a vital aspect of the human development. With a non-functioning fertility system future generations would be at a loss. Many problems could arise with infertility and ground-breaking research is finally being conducted. One of the important aspects of human reproduction is the use of hormones specifically FSH (Follicle Stimulating Hormone). This hormone is produced at the base of the brain stem and non-existing levels of FSH were recently associated with infertility. In order to regenerate these hormones a change has to be made in the FSHB subunit of the nucleotide. Infertility usually occurs after certain changes are made in the hormone levels and by redirecting the levels of hormones we may be able to alter the problems that arise during reproduction. It should also be noted that increases and decreases in the levels of FSH may have different effects depending on the gender of the patient. Current research estimates that the response of males to this therapy could positively effect nearly 45% of infertile men. Estimates could not be made for females as a result of insufficient research.

Vaccination Statistics - 0 views

  •  
    Although popularized by the media as "healthy," vaccinations bring more harm to the human body then they do health. Multiple studies have found that those children injected with vaccinations actually caught more disease than those not vaccinated. Vaccinations are not guaranteed to work, and can actually cause severe complications. Few vaccinations have been successful; these effective immunizations protect against one disease, but increase risk of other viruses. Vaccines contain harmful ingredients that can cause cancers and leukemia, and are even linked to AIDS. Vaccines are also connected to brain damage, lowered IQ, ADD, learning disabilities, and autism. Vaccinations are composed of harmful ingredients, are illogically produced, and cause more diseases than they prevent.

Scientists Use Stem Cells to Grow Mouse Inner Ears - 0 views

  •  
    Recent stem cell research has enabled scientists to develop mice inner ears. This new discovery has high hopes to lead to future hearing restoration for humans, and reasoning on hear loss. This astonishing breakthrough is the result of the transformation of embryonic stem cells from mice into sensory epithelia. These epithelia contain hair cells, fragile cells that allow organisms to hear. This discovery is even more shocking through the impossibility for hair cells to grow once they have been destroyed. This exciting accomplishment allows for researchers to study hair cells, and their connection to hearing.
