Discrepancies in access to new cancer drugs revealed

Access to potentially life-extending cancer drugs varies significantly in different regions of the world, two new studies show at the ESMO 2014 Congress in Madrid, Spain.

Researchers say the results demonstrate the need for better collaboration between doctors and health authorities on an international scale, to ensure patients have access to the best treatments.

Protein 'map' could lead to potent new cancer drugs

Imperial chemists have gained fresh insights into how a disease-causing enzyme makes changes to proteins and how it can be stopped.

The scientists hope their findings will help them to design drugs that could target the enzyme, known as N-myristoyltransferase (NMT), and potentially lead to new treatments for cancer and inflammatory conditions.

They have already identified a molecule that blocks NMT's activity, and have identified specific protein substrates where this molecule has a potent impact.

The discovery of 27 vertebrates fully reveals the unmatched biodiversity in Tanzania

A study by an international team of scientists coordinatedby Italy's MUSE - Science Museum updates knowledge on the faunal richness of the Eastern Arc Mountains of Tanzania and Kenya; presents the discovery of 27 new vertebrate species (of which 23 amphibians and reptiles); identifies the drivers of the area's exception biological importance and advocates for its candidature to the UNESCO's List of World Heritage Sites.

Experts call for a moratorium on use of new internet domain .health

As the Internet Corporation for Assigned Names and Numbers (ICANN) moves forward with plans to launch health-related generic top-level domains (gTLD), such as .health and .doctor, a coalition of health policy academics and clinicians are raising concerns about a process they say "favor[s] business interests and the generation of profits over the future integrity of the Health Internet."

Viral infection in transplant recipients increases risk of developing damaging antibodies

Washington, DC (September 25, 2014) — Kidney transplant recipients infected with BK virus are more likely to develop antibodies against their kidney transplants than uninfected patients, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). Future treatment strategies should focus on simultaneously clearing BK infections while protecting against risks of transplant rejection.

Dunes reveal biodiversity secrets

Ancient, acidic and nutrient-depleted dunes in Western Australia are not an obvious place to answer a question that has vexed tropical biologists for decades. But the Jurien Bay dunes proved to be the perfect site to unravel why plant diversity varies from place to place. Smithsonian Tropical Research Institute scientist Benjamin Turner and colleagues from the University of Western Australia published findings in the Sept.

Tropical disease prevalence in Latin America presents opportunity for US

HOUSTON – (Sept. 25, 2014) – Recently published prevalence estimates of neglected tropical diseases (NTDs) in five Latin American countries — Bolivia, Cuba, Ecuador, Nicaragua and Venezuela — could suggest a new direction for United States foreign policy in the region, according to a tropical-disease expert at Rice University's Baker Institute for Public Policy.

Gastric bypass bests banding for weight loss, diabetes, high blood pressure and cholesterol control

DALLAS – Sept. 25, 2014 – Gastric bypass surgery has better outcomes than gastric banding for long-term weight loss, controlling type 2 diabetes and high blood pressure, and lowering cholesterol levels, according to a new review by UT Southwestern Medical Center surgeons of nearly 30 long-term studies comparing the two types of bariatric procedures.

Bariatric surgery not a magic wand to curb depression

Most severely obese people experience much better spirits once they shed weight through a diet, lifestyle changes or medical intervention. This is unfortunately not true for everyone, says Valentina Ivezaj and Carlos Grilo of the Yale University School of Medicine in the US. In an article in Springer's journal Obesity Surgery, the researchers advise that the levels of depression in patients be measured six to 12 months after they have had such bariatric surgery. This will ensure that the necessary help can be provided when needed.

Genetic 'instruction set' for antibodies knocks down hepatitis C in mice

A triple-punch of antibodies both prevented hepatitis C infection and wiped out the disease after it had established itself in laboratory mice, according to a study led by Princeton University researchers. Instead of delivering the three antibodies directly, the researchers administered a genetic "instruction set" that, once in a cell, developed into antibodies that target the portions of the virus that do not mutate.

Study: Widespread vitamin D deficiency in thyroidectomy patients

DETROIT – A new study from researchers at Henry Ford Hospital in Detroit finds widespread vitamin D deficiency among patients who undergo a thyroidectomy, potentially putting them at greater risk for developing dangerously low blood calcium levels after surgery.

Among the patients in the Henry Ford study, 40 percent had low vitamin D levels prior to surgery. Those more likely to be vitamin D deficient are individuals older than age 50, African Americans, Hispanics and patients undergoing surgery for hyperthyroidism.

Stem cell transplant does not cure SHIV/AIDS after irradiation of infected rhesus macaques

A study published on September 25th in PLOS Pathogens reports a new primate model to test treatments that might cure HIV/AIDS and suggests answers to questions raised by the "Berlin patient", the only human thought to have been cured so far.

Stone Age site challenges old archaeological assumptions about human technology

The analysis of artifacts from a 325,000-year-old site in Armenia shows that human technological innovation occurred intermittently throughout the Old World, rather than spreading from a single point of origin, as previously thought.

Agonizing rabies deaths can be stopped worldwide

The deadly rabies virus--aptly shaped like a bullet-- can be eliminated among humans by stopping it point-blank among dogs, according to a team of international researchers led by the Paul G. Allen School for Global Animal Health at Washington State University.

Innovative Stone Age tools were not African invention, say researchers

A new discovery of thousands of Stone Age tools has provided a major insight into human innovation 325,000 years ago and how early technological developments spread across the world, according to research published in the journal Science.
