Use of antibiotic following kidney transplantation does not prevent virus infection

Among kidney transplant recipients, a 3-month course of the antibiotic levofloxacin following transplantation did not prevent the major complication known as BK virus from appearing in the urine. The intervention was associated with an increased risk of adverse events such as bacterial resistance, according to a study appearing in JAMA. The study is being released to coincide with its presentation at the American Society of Nephrology's annual Kidney Week meeting.

Osteoporotic fractures cost China's healthcare system close to 10 billion USD annually

Taipei, November 15, 2014 - An epidemiological study presented today at the 5th Asia-Pacific Osteoporosis Meeting is one of the first to project the immense and growing economic cost of osteoporotic fractures in China.

Scientists uncover mechanism that controls the fitness of cells, impacting aging and disease

DALLAS - November 15, 2014 - A novel looping mechanism that involves the end caps of DNA may help explain the aging of cells and how they initiate and transmit disease, according to new research from UT Southwestern Medical Center cell biologists.

The UT Southwestern team found that the length of the endcaps of DNA, called telomeres, form loops that determine whether certain genes are turned off when young and become activated later in life, thereby contributing to aging and disease.

Weight-loss surgery may improve kidney function

Philadelphia, PA (November 14, 2014) -- In addition to helping patients shed pounds, weight loss surgery may also improve kidney function, according to a study that will be presented at ASN Kidney Week 2014 November 11¬-16 at the Pennsylvania Convention Center in Philadelphia, PA.

Genetic testing for personalized nutrition leads to better outcomes

Researchers from the University of Toronto (U of T) report that personalized dietary advice based on a person's genetic makeup improves eating habits compared to current "one-size-fits-all" dietary recommendations. The findings were published online today in the journal PLoS One.

New special report highlights NSF-funded broader impacts

Each year, the National Science Foundation (NSF) receives about 50,000 proposals for research funding in all fields of science and engineering from all corners of the country. NSF distinguishes among the proposals through a competitive review process built on two criteria: intellectual merit and broader impacts--will the research advance knowledge and will it benefit society?

Today, NSF released a special report to showcase broader impacts and examples of the diverse and far-reaching ways NSF-supported science touches our lives.

What's the current role of liver biopsy in children? Position paper in Journal of Pediatric Gastroenterology and Nutrition

November 14, 2014 - While noninvasive alternatives are increasingly available, liver biopsy still provides essential information in some children with liver disease, according to a new position paper in the Journal of Pediatric Gastroenterology and Nutrition, official journal of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition.

Rocky Mountain storms lead to new findings about hailstones

BOZEMAN, Mont. - Hailstones from three Rocky Mountain storms formed around biological material, then bounced around the clouds picking up layers of ice, according to a new Montana State University study.

Cutting-edge computer software helps pinpoint aggressiveness of breast cancer tumors

Researchers at Western University are using cutting-edge genetic mutation-analysis software developed in their lab to interpret mutations in tumour genome that may provide insight into determining which breast cancer tumours are more likely spread to other parts of the body and which ones won't.

Their findings are published today in the journal, Nature Scientific Reports.

New imaging technique identifies receptors for targeted cancer therapy

Dartmouth researchers have developed a fluorescence imaging technique that can more accurately identify receptors for targeted cancer therapies without a tissue biopsy. They report on their findings in "Quantitative in vivo immunohistochemistry of epidermal growth factor receptor using a receptor concentration imaging approach," which was recently published in Cancer Research.

A kingdom of cave beetles found in Southern China

A team of scientists specializing in cave biodiversity from the South China Agricultural University (Guangzhou) unearthed a treasure trove of rare blind cave beetles. The description of seven new species of underground Trechinae beetles, published in the open access journal ZooKeys, attests for the Du'an karst as the most diverse area for these cave dwellers in China.

Conventional therapies are less efficient in prostate cancer patients carrying 'BRCA' mutations

Prostate cancer patients carrying inherited mutations in the BRCA genes respond less well to conventional treatment, including surgery and/or radiotherapy - and they also have a lower survival rate than those who are non-carriers of these genetic mutations. Data from the study, which has been published in the journal European Urology, points to the need for new clinical trials aimed at targeting these mutations in order to tailor treatment for these patients.

Scientists unlock crucial mechanism driving colliding epidemics of smoking and TB

DUBLIN, Ireland, November 14th, 2014 - TB is an infectious disease that kills 1.5 million people each year, and smoking is the biggest driver of the global TB epidemic. Medical scientists at Trinity College Dublin and St James's Hospital in Ireland have unlocked the mechanism underlying the connection between smoking and Tuberculosis (TB). This discovery will considerably strengthen anti-smoking efforts to control TB and uncovers new therapy and vaccine options for TB.

DNA sequencing helps identify genetic defects in glaucoma

Scientists from the University of Liverpool have sequenced the mitochondrial genome in glaucoma patients to help further understanding into the genetic basis for the disease.

Glaucoma is a major cause of irreversible blindness, affecting more than 60 million people worldwide, increasing to an estimated 79.6 million people by 2020. It is thought that the condition has genetic origins and many experiments have shown that new sequencing approaches could help understand how the condition develops.

New insight into common cause of blindness

Age-related Macular Degeneration (AMD) is the major cause of blindness in the western world, affecting around 50 million people. It has been shown that sufferers are genetically predisposed to develop the condition.
