University of California study may shed light on human ability to adapt hypoxia

In an important study that may shed light on human ability to adapt to hypoxia, or inadequate levels of oxygen, researchers at the University of California, San Diego School of Medicine have proven that the genome of flies exposed to long-term hypoxia are changed to permanently affect gene expression.

Women pregnant after egg donation are high-risk patients

Women who have become pregnant after egg donation should be categorized as high-risk patients. Why that is the case, and which consequences egg donation may have for women is the subject of a review article by Ulrich Pecks and co-authors from the University Hospital Aachen in the current issue of Deutsches Ärzteblatt International.

Rogue gene blocked by right drugs could stop cancer

Scientists at the University of East Anglia (UEA) have discovered a rogue gene which - if blocked by the right drugs - could stop cancer in its tracks.

Breakthrough in understanding mechanisms behind hereditary alpha-1-antitrypsin deficiency

Researchers from the Royal College of Surgeons in Ireland (RCSI) and Beaumont Hospital have made a breakthrough in understanding the mechanisms behind the most severe form of hereditary emphysema and how protein treatments can improve the condition. The findings of this study may also lead to new treatments for patients with smoker's emphysema.

Contagious cancer repairs own genetic mutations

A curious contagious cancer, found in dogs, wolves and coyotes, can repair its own genetic mutations by adopting genes from its host animal, according to a new study in the journal Science.

Nutrient 'biomarkers' may help assess nutrient status of elderly people at risk for dementia

Research is trying to determine whether Alzheimer's disease might be slowed or prevented with nutritional approaches, but a new study suggests those efforts could be improved by use of nutrient "biomarkers" to objectively assess the nutrient status of elderly people at risk for dementia.

Mystery of 'inactive' defensin solved

Under standard laboratory conditions, the human beta-defensin 1 (hBD-1), a human antibiotic naturally produced in the body, had always shown only little activity against microbes. Nevertheless the human body produces it in remarkable quantities.

Psychological Science journal releases new research findings

The insula has been implicated in evaluative and affective processes. New findings indicate that the insula may be broadly involved in integrating affective and cognitive processes. Participants rated the positivity and negativity of picture stimuli and how emotionally arousing they found the pictures to be.

Research findings reveal HIV's hiding spot, new way to stop the virus

HIV adapts in a surprising way to survive and thrive in its hiding spot within the human immune system, scientists have learned. While the finding helps explain why HIV remains such a formidable foe after three decades of research - more than 30 million people worldwide are infected with HIV - it also offers scientists a new, unexpected way to try to stop the virus.

Functional tests are necessary to understand human disease despite genetic sequencing

Despite what you might have heard, genetic sequencing alone is not enough to understand human disease. Researchers at Duke University Medical Center have shown that functional tests are absolutely necessary to understand the biological relevance of the results of sequencing studies as they relate to disease, using a suite of diseases known as the ciliopathies which can cause patients to have many different traits.

Researchers identify key player that lead to increased bleeding in diabetes patients with stroke injury

Strokes are a leading cause of mortality and adult disability. Those that involve intracerebral hemorrhage are especially deadly, and there are no effective treatments to control such bleeding. Moreover, diabetes and hyperglycemia are associated with increases in bleeding during hemorrhagic stroke and worse clinical outcomes.

Stusy: HEPA filters may help reduce pollution-related cardiovascular health risks

Using inexpensive air filters may help reduce cardiovascular disease risk that results from exposure to air pollution, according to researchers from Canada, who studied healthy adultsliving in a small community in British Columbia where wood burning stoves are the main sources of pollution.

CRI, Oncovir sign new investment agreement to produce immunological stimulant

Cancer Research Institute, a U.S. nonprofit organization founded in 1953 to advance the science of tumor immunology and foster the discovery and development of new cancer immunotherapies, announced today that its Cancer Vaccine Acceleration Fund, a joint initiative with the Ludwig Institute for Cancer Research, has completed a new investment agreement with Oncovir, a biotechnology company based in Washington, D.C., to enable the production of the immunological stimulant Hiltonol- (Poly-ICLC).

Environmental contaminant levels in mother's body decrease during breast-feeding: Study

The levels of environmental contaminants in a mother's body decrease during breast-feeding. After a year of lactation, the levels of a number of environmental contaminants in breast milk drop by 15 - 94 per cent, according to a recent study from the Norwegian Institute of Public Health. There has been little study into this topic previously.

Odontoblast cells are part of immune system, protect teeth from decay: New research

It is known that teeth can protect themselves, to some extent, from attack by bacteria but that inflammation within a tooth can be damaging and, in extreme cases, lead to abscess or death of the tooth. New research published in BioMed Central's open access journal BMC Immunology shows that odontoblast cells are part of the immune system and fight to protect teeth from decay.

FibroGen announces FG-3019 interim results from phase 1/2 trial against pancreatic cancer

FibroGen, today announced interim results of a phase 1/2 trial of FG-3019, a therapeutic antibody against connective tissue growth factor, in combination with gemcitabine and erlotinib in individuals with unresectable pancreatic cancer.

Mutation of microRNA miR-96 causes deafness

New research from the University of Sheffield has revealed that the molecular mechanism underlying deafness is caused by a mutation of a specific microRNA called miR-96. The discovery could provide the basis for treating progressive hearing loss and deafness.

Anti-depressants are passing into waterways and affecting fish

Around one in four Montrealers take some kind of anti-depressant, and according to new research, the drugs are passing into the waterways and affecting fish. The findings are internationally significant as the city's sewage treatment system is similar to that in use in other major cities, and moreover, it is reputed to be the third largest treatment system in the world.
