Discovery of inherited gene variants that account for 37 percent of childhood acute lymphoblastic leukemia

Scientists at St. Jude Children’s Research Hospital have identified inherited variations in two genes that account for 37 percent of childhood acute lymphoblastic leukemia (ALL), including a gene that may help predict drug response.

Abuse, self-neglect places seniors at increased risk for premature death

Older adults who are subjected to abuse or self-neglect face a greater risk of premature death than other seniors, according to a study published in the medical journal JAMA.

New target for Alzheimer's disease

For close to a decade, pharmaceutical researchers have been in hot pursuit of compounds to activate a key nicotine receptor that plays a role in cognitive processes. Triggering it, they hope, might prevent or even reverse the devastation wrought by Alzheimer’s disease.

New biomarker predicts response to hepatitis C treatment

Researchers have identified the first genetic marker that predicts response to hepatitis C treatments, and a single letter of DNA code appears to make a huge difference. Duke University Medical Center scientists says the biomarker not only predicts who is most likely to respond to treatment and who isn't, but also may explain why there are such different rates of response among racial and ethnic groups, a phenomenon that has puzzled physicians for years.

Novel treatment reduces swollen livers

Viruses need living cells for replication and production of virus progeny. Thus far, antiviral therapy primarily targets viral factors but often induces therapy resistance. New improved therapies attempt to targets cellular factors that are essential for viral replication.

New study suggests possible genetic link between environmental toxins and myeloma

The International Myeloma Foundation (IMF) today said newly published data may provide a possible genetic link between environmental toxins and bone disease in multiple myeloma. Myeloma, also called multiple myeloma, is a cancer of cells in the bone marrow that affect production of blood cells and can damage bone.

Scientists create new method to detect genetic causes of complex diseases

Computational biologists at Carnegie Mellon University have developed an analytical technique to detect the multiple genetic variations that contribute to complex disease syndromes such as diabetes, asthma and cancer, which are characterized by multiple clinical and molecular traits.

Gay people more likely to have mental health or substance use disorders

Members of ‘sexual minorities’ are around twice as likely as heterosexuals to seek help for mental health issues or substance abuse treatment. A model of treatment-seeking behavior, described in the open access journal BMC Psychiatry supports the idea that lesbian, gay and bisexual people may have specific treatment needs.

Tissue scarring key to link between obesity and diabetes

The team, in collaboration with University Hospital Aintree, the University of Warwick and researchers in Sweden, found that people classified as obese and those with pre-diabetes have raised levels of a protein called SPARC, that can cause tissue scarring.

When cell death goes wrong - scientists gain new insights

Medical Research Council (MRC) scientists have made an important advance in understanding the biological processes involved when cells are prompted to die. The work may help scientists to eventually develop new treatments for the many common diseases and conditions which occur when cell death goes wrong.

New tumour theory could change cancer treatment

University of Sydney researcher Dr Guy Lyons has come up with a new theory of cancer tumours that could change the way we treat cancer and conduct research into its causes.

Discovery of possible genetic link between environmental toxins and bone disease in multiple myeloma

The International Myeloma Foundation (IMF) - supporting research and providing education, advocacy and support for myeloma patients, families, researchers and physicians - today said newly published data may provide a possible genetic link between environmental toxins and bone disease in multiple myeloma.

Human brain distinctly separates living and non-living objects for processing

For unknown reasons, the human brain distinctly separates the handling of images of living things from images of non-living things, processing each image type in a different area of the brain. For years, many scientists have assumed the brain segregated visual information in this manner to optimize processing the images themselves, but new research shows that even in people who have been blind since birth the brain still separates the concepts of living and non-living objects.

Sigma-Aldrich offers customizable synthetic extracellular matrix (ECM) for stem cell research

Sigma-Aldrich (Nasdaq: SIAL) today announced an agreement with Glycosan BioSystems for the sale of HyStem(TM), a fully customizable synthetic extracellular matrix (ECM) for stem cell research. HyStem offers researchers flexibility to tailor microenvironments for their cultured cells that mimic natural in vivo conditions, optimizing stem cell proliferation and differentiation. HyStem was developed by Glycosan BioSystems and will be sold by Sigma-Aldrich under a non-exclusive distribution agreement.

Wine may offer radioprotective effect for breast cancer patients

Drinking wine while undergoing radiation treatment for breast carcinoma may reduce the incidence of skin toxicity in breast cancer patients, according to a study in the August issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO).

Why GPs won’t take part in research

A group of researchers whose planned leg ulceration study was hamstrung by a physician recruitment rate of 2% have published the reasons why so many doctors turned them down. The qualitative information, featured in the open access journal BMC Medical Research Methodology, should be of use to those designing trials of their own.

Discovery of compounds that selectively kills cancer stem cells

The cancer stem cells that drive tumor growth and resist chemotherapies and radiation treatments that kill other cancer cells aren't invincible after all. Researchers reporting online on August 13th in the journal Cell, a Cell Press publication, have discovered the first compound that targets those cancer stem cells directly.
