Easy Frame Size Adjustment On Karma Wheelchair - 0 views

  •  
    Utilizing small wheels and lighter materials, transport wheelchairs can tip the scale at as little as 19 lbs., ideal for those looking for a highly portable option. Transport chairs also tend to be more affordable and offer the benefit of increased mobility without breaking the bank. This type of lightweight wheelchair is often referred to as a "transfer chair" and is typically used for shorter trips. Since it's geared towards storability and portability, it features four smaller wheels and dispenses with the larger, rear-mounted wheels that characterize standard wheelchairs. Its construction ensures that it's always foldable and portable, but does so at the expense of self-propulsion. Instead, a transport chair is built so that a caregiver can easily push the user from point A to B. Transport Wheelchair features a lightweight aluminum frame with a multiple finish options. It comes standard with padded-permanent armrests and swing-away footrests with composite footplates. It is an ideal solution for easy transportation and storage.

With the development and heightened popularity and usage of wheelchairs, such handicapped people are given more advantage and privilege. The emergence of transport wheelchairs have significantly helped improve the way people make use of wheelchairs. Transport wheelchairs are machines or equipment that facilitate for mobility and movement of wheelchair confined people at public places. While it is true that simple wheelchairs can do the trick, transport wheelchairs are specifically designed and manufactured to facilitate better roaming and mobility at malls, restaurants and parks where people usually converge to relax. Transport wheelchairs provide many advantages: Weight: As the name implies, they are easy to transport because they typically weigh around 15 to 20 pounds, which is much less than a manual wheelchair.

Walgreens Starts Strategic Review For Boots UK - 0 views

  •  
    Walgreens Boots Alliance, the parent company of Boots UK, has begun a strategic review of its business in the United Kingdom, chief executive officer Rosalind Brewer said on Tuesday (January 11) - as the pharmacy chain tries to renew its focus on US healthcare. Boots has over 2,200 stores across the UK, which include pharmacies, health and beauty stores, among others, according to the chain's website. "This review is very much in line with our renewed priorities and strategic direction. In particular, our increased focus on US healthcare. While the process is at an exploratory stage, we do expect to move quickly," Brewer said at the JP Morgan Healthcare Conference. The review comes at a time when the company, which was formed in 2014 after the acquisition of stake in Alliance Boots by Walgreens, moves beyond its drugstores with its investments in two smaller healthcare providers, CareCentrix and VillageMD.

Insomnia What You Know and What You Don't! - 0 views

  •  
    Most of you would know that insomnia is a sleep problem, and it causes difficulty in falling asleep and staying asleep for a reasonable amount of time. It also affects sleep quality, resulting in daytime inactivity. Most of the time, insomnia can become long-term. This long-term insomnia is called chronic insomnia. This type of insomnia is diagnosed when the patient has trouble sleeping, at least 3 to 4 days a week for at least one month. Acute insomnia or short-term insomnia is the most common type of insomnia that most people have today. As the name suggests, it is a short-term illness and lasts only for a few days or at most three to four weeks. Consult your doctor, get a proper check-up, explain all the problems including your sleep schedule. Initially, severe insomnia symptoms may not require adequate treatment. If a person feels tired and cannot perform his physical activities during the day, he should buy sleeping pills for a short time as per the prescription of his doctor or physician. If your symptoms are not under control, use cheap Temazepam 10 mg tablets available online. You can buy these insomnia pills online from Pharma Health Online.

  • these findings provide further support that E2 and BPA maintain the stem-like state within the normal prostate epithelial cell population
  • Our previous findings demonstrated that normal prostate stem-progenitor cells within the prostaspheres expressed ERα and ERβ, implicating them as direct targets for E2 and BPA action
  • p-Akt and p-Erk, well established downstream targets of membrane-associated ERs
  • BPA and E2 had equimolar capacity for activation of these rapid signaling pathways in human prostaspheres, thus identifying a dynamic and robust signaling pathway initiated by low-dose BPA exposure in prostate stem-progenitor cells.
  • these findings indicate that both rapid membrane-initiated estrogen action and genomic ER signaling pathways are operative in human prostate progenitor cells.
  • these results document the fact that levels of bioactive BPA in the present study are similar to levels found in human umbilical cord blood and newborns in the general population
  • the present findings identify for the first time that in vivo exposure of the human prostate epithelium to low doses of BPA significantly increases the susceptibility of the human prostate epithelium to hormonal carcinogenesis.
  • The current study provides clear evidence that, similar to E2, normal human prostate stem and progenitor cells are direct targets for BPA action
  • Both hormones increased stem-like cell numbers in primary prostate epithelial cultures in a dose-dependent manner and augmented the number and size of 3-D cultured prostaspheres, markers of stem cell self-renewal and progenitor cell proliferation, respectively
  • signaling pathways engaged by estrogens through these separate receptors are multiple and complex, including both membrane-initiated signaling and genomic activation via ER transcriptional activity
  • Estrogen action is mediated by ERα and ERβ
  • the current results indicate that developmental exposure to BPA, at doses routinely found in humans, significantly increases the cancer risk in human prostate epithelium in response to elevated estrogen levels in an androgen-supported milieu. Because relative estrogen levels rise in aging men, we suggest that humans may be susceptible to BPA-driven prostate disease in a manner similar to that in the rodent models.
  • We propose that early-life perturbations in estrogen signaling including inappropriate exposure to BPA have the potential to amplify and modify the stem-progenitor cell populations within the human prostate gland and, in so doing, alter the normal homeostatic mechanisms that maintain a growth neutral state throughout life

    Pediatric wheelchairs enable child or teen to participate in all types of daily activities. Pediatric wheelchairs are lightweight, portable, and convenient for use at school, day programs, doctor visits, and recreation with family and friends. Pediatric wheelchairs comes in wide range of sizes and vibrant colors for every lightweight wheelchair. A variety of positioning options are also available. Pediatric wheelchairs are manufactured with unsurpassed quality and style, specializing in compact-folding, lightweight wheelchairs for children of all ages - from toddlers to teens! Custom built to child's specific needs, mobility aids offer rehabilitative benefits for physical disabilities from Cerebral Palsy to Autism. Pediatric, or child wheelchairs, are mobile aids designed for and used by children. Children require the use of a wheelchair for many different reasons, some may have suffered head injuries, some have muscular dystrophy or cerebral palsy, some are amputees, and others only have an occasional use of their wheelchairs in lieu of a walking device or crutches. Certain types of pediatric wheelchairs are built to expand in size to accommodate increased bulk and weight by altering a cross balance on the bottom of the chair. The front frames for the legs can be lengthened as child's legs grow longer. For a pediatrician seeking to prescribe a Pediatric Wheelchair, must be sure that the patient has the proper upper body strength to use one. If the patient is too weak for self movement, the practitioner would be better to consider a powered wheelchair for mobility. While Pediatric Wheelchairs are smaller and can be just as manuverable as scooters, that depends upon the patient's own abilities in steering the chair. These are factors that the doctor must think about before recommending what type of wheelchair a patient should get. Pediatric Wheelchair with a body contouring S-Shaped seat frame and contoured armrests provides the user with all day comfort an

The implication of neuroactive steroids in Tourette syndrome pathogenesis: a ... - 0 views

  • The typical onset of TS occurs at 6–7 years of age and is characterized by the appearance of simple, recurrent motor tics, followed by the manifestation of phonic tics after several months [12]. In most children, TS symptoms undergo a progressive exacerbation, which reaches its zenith at the beginning of puberty (11–12 years of age), and is then followed by a gradual remission in the majority of patients
  • 30–40% of TS-affected children retain their symptoms in adulthood
  • Multiple neurotransmitters have been implicated in TS, including dopamine (DA), serotonin, norepinephrine, acetylcholine, glutamate and γ-amino-butyric acid (GABA)
  • ...11 more annotations...
  • female gender may predict greater tic severity in adulthood
  • male gender is a major risk factor for TS (with a male:female prevalence ratio estimated at ~4:1)
  • the typical age of onset coincides with adrenarche (6–7 years old); symptoms increase in severity until the beginning of puberty (12 years old) and then undergo a spontaneous amelioration, which becomes apparent with the end of puberty (at 18–19 years of age)
  • TS is diagnosed later in females than males
  • ample evidence supports the involvement of DAergic dysfunctions in TS
  • a number of clinical observations showed that tics in TS patients could be exacerbated by anabolic androgens
  • steroidogenic enzymes and androgen receptors may serve as putative therapeutic targets for this disorder
  • Unlike males, tic severity is typically increased after puberty in females
  • 26% of females were found to experience exacerbation of tics in the estrogenic phase of the menstrual cycle, and this phenomenon was found to be correlated with increased tic severity at menarche
  • biochemical hallmark of adrenarche is the acquisition of 17,20 lyase activity by cytochrome P450 C17 (CYP17A1)
  • increased synthesis of dehydroepiandrosterone (DHEA) and androstenedione, which leads to the growth of axillary and pubic hair as well as enhancement in the oiliness of the skin
  •  
    interesting read on hormones and tourette's.. Proposed that 5 alpha reductase activity is involved in worsening of tics.  This makes sense as Testosterone in men with low T is known to increase dopamine and dopaminergic dysfunction is known to play a role in tourette's;  the clinical presentation of girls vs boys is very different.  The authors of this article propose that 5 alpha reductase activity controls a back door method where by progesterone is converted to androgens.
