Researchers diagnose genetic disease in embryonic DNA without biopsy

Preimplantation genetic diagnosis (PGD) technologies allow identification of genetic disorders in human preimplantation embryos after in vitro fertilization (IVF) and before the embryo is transferred back to the patient.

Bioglass help human bone to regenerate, find UPV/EHU researchers

Jose Ramon Sarasua and Aitor Larra-aga, researchers in the materials engineering department of the UPV/EHU-University of the Basque Country, have been studying new materials or implants that are of interest in medicine and in helping to mend bones, in particular.

A new method to kill pathogenic bacteria

Engineering researchers at Rensselaer Polytechnic Institute have developed a new method to kill deadly pathogenic bacteria, including listeria, in food handling and packaging. This innovation represents an alternative to the use of antibiotics or chemical decontamination in food supply systems.

Targeting cholesterol metabolism in eye may prevent age-related macular degeneration, says study

Targeting cholesterol metabolism in the eye might help prevent a severe form of age-related macular degeneration (AMD), one of the most common causes of blindness in older Americans, according to indications in a study in mice, which was supported by the National Institutes of Health.

CRG researchers reprogramme lymphoma and leukaemia cells to halt malignancy

Researchers from the Centre for Genomic Regulation (CRG) in Barcelona reprogramme lymphoma and leukaemia cells to halt their malignancy. Resulting cells remain benign even when no longer subjected to treatment and reduce likelihood of developing new tumours.

Research findings shed light on how neurons translate sensory input into actions

New research by scientists at the University of Massachusetts Medical School shows at the single cell level how an external stimulus sets off a molecular chain reaction in the transparent roundworm C. elegans, a process in which a single neurotransmitter coordinates and times two separate actions.

PARP inhibitors can be novel treatment strategy for cisplatin-resistant cancer

Poly (ADP-ribose) polymerase inhibitors may be a novel treatment strategy for patients with cancer that has become resistant to the commonly used chemotherapy drug cisplatin, according to data from a preclinical study published in Cancer Research, a journal of the American Association for Cancer Research.

Imbalance between neutrophil elastase and α1-antitrypsin leads to obesity, inflammation

Many recent studies have suggested that obesity is associated with chronic inflammation in fat tissues. Researchers at Sanford-Burnham Medical Research Institute have discovered that an imbalance between an enzyme called neutrophil elastase and its inhibitor causes inflammation, obesity, insulin resistance, and fatty liver disease.

Report shows identical genetic mutations are shared among neurodevelopmental disorders

A paper published this month in the prestigious medical journal The Lancet Neurology suggests that a broad spectrum of developmental and psychiatric disorders, ranging from autism and intellectual disability to schizophrenia, should be conceptualized as different manifestations of a common underlying denominator, "developmental brain dysfunction," rather than completely independent conditions with distinct causes.

Salk neuroscientist applauds launch of BRAIN Initiative

Salk neuroscientist Terrence J. Sejnowski joined President Barack Obama in Washington, D.C., on April 2, 2013, at the launch of the Brain Research through Advancing Innovative Neurotechnologies Initiative-a major Administration neuroscience effort that advances and builds upon collaborative scientific work by leading brain researchers such as Salk's own Sejnowski.

RUB biologists report that vitamin P ensures survival of motor neurons in culture

Biologists from the Ruhr-Universit-t Bochum have explored how to protect neurons that control movements from dying off.

Doctors give new hope for leukemia patients

Leukemia patients receive a bone marrow transplant, which allows them to build a "new" immune system. However, this immune system not only attacks cancer cells but healthy tissue too.

Antibodies neutralize mosquito-transmitted chikungunya virus, researchers reveal

Researchers have learned the precise structure of the mosquito-transmitted chikungunya virus pathogen while it is bound to antibodies, showing how the infection is likely neutralized.

Obama to announce initiative to map human brain

The New York Times reports that President Barack Obama will unveil a broad new research initiative Tuesday, starting with $100 million next year, to find ways to record and map human brain circuits.

Kavli Foundation applauds launch of new brain research initiative

The Kavli Foundation applauds today's launch by President Obama of his Administration's ambitious research effort to understand the brain by deciphering the brain's activity that gives rise to our perceptions, our experiences and our consciousness.

Researchers find association between melatonin, type 2 diabetes

With previous evidence suggesting that melatonin may have a role in glucose metabolism, researchers have found an independent association between decreased secretion of melatonin and an increased risk for the development of type 2 diabetes, according to a study in the April 3 issue of JAMA.

CU Cancer Center researchers identify switch that regulates production of E-Cadherin

Prostate cancer doesn't kill in the prostate - it's only once the disease travels to bone, lung, liver, etc. that it turns fatal. Previous studies have shown that loss of the protein E-Cadherin is essential for this metastasis.

UC Davis scientists find mechanism in metabolized omega-3 fatty acid that helps combat cancer

A team of UC Davis scientists has found that a product resulting from a metabolized omega-3 fatty acid helps combat cancer by cutting off the supply of oxygen and nutrients that fuel tumor growth and spread of the disease.

Study shows cholesterol rafts can shepherd genetic payloads into cancer cells

DNA, siRNA and miRNA can reprogram cancer cells - that is, if these nucleic acids could cross through the cell membrane. A University of Colorado Cancer Center study published today in the journal Therapeutic Delivery shows that cholesterol "rafts" can shepherd genetic payloads into cancer cells.

Scientists use multi-analyte approach to determine exposure to tobacco constituents of snus users

Scientists at British American Tobacco have used a multi-analyte approach to determine the level of exposure to tobacco constituents of snus users. The results show that, generally, less than a third of each constituent measured was extracted by consumers during use.
