Study: Chromosomal microarray analysis detects genetic changes related to ASDs better than standard tests

A large study from Children's Hospital Boston and the Boston-based Autism Consortium finds that a genetic test that samples the entire genome, known as chromosomal microarray analysis, has about three times the detection rate for genetic changes related to autism spectrum disorders (ASDs) than standard tests. Publishing in the April issue of Pediatrics (and online March 15), the authors urge that CMA become part of the first-line genetic work-up for ASDs.

UC Irvine researchers play leading role in genome sequencing of Hydra

UC Irvine researchers have played a leading role in the genome sequencing of Hydra, a freshwater polyp that has been a staple of biological research for 300 years.

Supplementing vitamin D in people with low levels may have different effects based on patient race

Vitamin D is quickly becoming the "go-to" remedy for treating a wide range of illnesses, from osteoporosis to atherosclerosis. However, new evidence from a Wake Forest University School of Medicine study suggests that supplementing vitamin D in those with low levels may have different effects based on patient race and, in black individuals, the supplement could actually do harm.

XOMA 052 reduces adverse consequences that lead to development of congestive heart failure

XOMA Ltd., a leader in the discovery and development of antibody therapeutics, announced results demonstrating that a murine equivalent of XOMA 052, its novel, high-affinity antibody to interleukin-1 beta (IL-1 beta), significantly reduced adverse consequences that usually lead to the development of congestive heart failure in a mouse model of acute myocardial infarction (heart attack).

New laboratory technique may help prioritize cancer drugs for clinical trials

Improving on traditional screening tests for potential anti-cancer drugs, scientists at Dana-Farber Cancer Institute have developed a laboratory technique that more closely simulates the real-world conditions in which tumor cells mingle with the body's normal cells.

Puzzle baffled scientists for centuries - why some birds appear to be half male and half female solved

A puzzle that has baffled scientists for centuries - why some birds appear to be male on one side of the body and female on the other - has been solved by researchers.

Discovery may yield new strategies for blocking malaria transmission

Scientists studying the Anopheles gambiae mosquito - the main vector of malaria - have found that when the mosquito takes a blood meal, that act triggers two enzymes to form a network of crisscrossing proteins around the ingested blood.

New findings shed light on how genetic damage to muscle cell proteins can lead to nemaline myopathy

New findings that shed light on how genetic damage to muscle cell proteins can lead to the development of the rare muscle-wasting disease, nemaline myopathy, are reported today (15 March) in the Biochemical Journal.

New findings may help develop potential therapies for lupus, rheumatoid arthritis and cancer

Medical Research Council (MRC) scientists at the University of Leicester have made a new advance in understanding how the body fights certain types of cancer and other disease such as Lupus and rheumatoid arthritis.

Nanoparticles provide a targeted version of photothermal therapy for cancer

In a lecture he delivered in 1906, the German physician Paul Ehrlich coined the term Zuberkugel, or "magic bullet," as shorthand for a highly targeted medical treatment.

Obese type 2 diabetics carry mitochondrial proteins that reduce response to physical exercise

Diet and aerobic exercise are highly effective for the treatment of type 2 diabetes, but not for obese subjects that have developed the disease when very young. A study at the Institute for Research in Biomedicine and Trinity College in Dublin demonstrates that obese subjects between 18 and 25 years of age carry mitochondrial proteins and genes that work abnormally and that these anomalies contribute to generating insulin resistance and a reduced response to physical exercise.

Keystone Symposia receives NIH grant for diversity initiatives

Keystone Symposia on Molecular and Cellular Biology is pleased to announce receipt of a $1.37 million, five-year MARC (Minority Access to Research Careers) Ancillary Training Activities grant from the National Institute of General Medical Sciences of the National Institutes of Health (NIH).

Two controlled environmental variables to preclinical mice tests can reduce costly false positives: Study

For decades, the traditional practice in animal testing has been standardization, but a study involving Purdue University has shown that adding as few as two controlled environmental variables to preclinical mice tests can greatly reduce costly false positives, the number of animals needed for testing and the cost of pharmaceutical trials.

New study finds green tea extract may prevent Alzheimer's disease and dementia

Long known to be beneficial in heart disease, diabetes and some cancers, a new study finds a specific green tea extract may delay or prevent Alzheimer's disease and dementia. A. Holliday & Company's "Teawell 50," is a 50 percent pure extraction of EGCG (epigallocatechin gallate) – a flavonoid which is the most potent of four major catechins in green tea.

Discovery of MiR-451 molecule may serve as a biomarker for brain tumor

Cancer cells in rapidly growing brain tumors must adjust to periods of low energy or die. When energy levels are high, tumor cells grow and proliferate. When levels are low, the cells grow less and migrate more.

ARS study underlines the importance of vitamin D and its ability to help body utilize calcium

Increasing calcium intake is a common--yet not always successful--strategy for reducing bone fractures. But a study supported in part by the Agricultural Research Service (ARS) underscores the importance of vitamin D and its ability to help the body utilize calcium. The study also may explain why increasing calcium alone isn't always successful in dealing with this problem.

Childhood obesity: Genetic variation could be a factor

Increasing childhood obesity has worried governments and public health advisers in many countries. But a study of 300 children with severe obesity by the University of Cambridge and the Wellcome Trust Sanger Institute, suggest the problem may be more complicated than simply bad diet, overeating, or lack of exercise.

Flu infection during pregnancy may increase risk of schizophrenia in offspring

Rhesus monkey babies born to mothers who had the flu while pregnant had smaller brains and showed other brain changes similar to those observed in human patients with schizophrenia, a study at the University of Wisconsin-Madison in collaboration with the University of North Carolina at Chapel Hill has found.

Independently-conducted studies confirm significant bioavailability of orally delivered insulin

ACCESS PHARMACEUTICALS, INC. announced that it has received reports of significant bioavailability of orally delivered insulin in two independently-conducted animal studies. The studies, which confirm earlier findings, were performed as part of on-going work with commercial collaborators that are evaluating Access' Cobalamin™ Oral Drug Delivery Technology.

BDNF could someday play significant role in prevention of high blood pressure: Study

Researchers at Oregon Health & Science University's School of Dentistry (www.ohsu.edu/sod) have discovered that nitric oxide is a powerful regulator of a molecule that plays a critical role in the development and function of the nervous system. The finding could someday play a significant role in the prevention and treatment of high blood pressure, which affects about one in three adults in the United States.
