Glutamic acid linked to lower blood pressure

Glutamic acid may be one of the components responsible for the lower blood pressures of people with vegetable-rich diets, according to a study published today in Circulation: Journal of the American Heart Association. Glutamic acid is a major component of protein; vegetable protein contains higher levels of glutamic acid than animal protein.

Research pinpoints antibodies that may prevent Alzheimer's

Antibodies to a wide range of substances that can aggregate to form plaques, such as those found in Alzheimer's patients, have been identified in the blood and cerebrospinal fluid of healthy people. Levels of these antibodies decline with age and, in Alzheimer's patients, with increasing progression of the disease.

Amino acid commonly found in vegetable protein may lower blood pressure

Consuming an amino acid commonly found in vegetable protein may be associated with lower blood pressure, researchers report in Circulation: Journal of the American Heart Association.

Specialized glycans act as tumor suppressors

Scientists at Burnham Institute for Medical Research (Burnham) have discovered that specialized complex sugar molecules (glycans) that anchor cells into place act as tumor suppressors in breast and prostate cancers.

A new prostate cancer "homing device" for drug delivery

A new prostate cancer "homing device" could improve detection and allow for the first targeted treatment of the disease. A team of Purdue University researchers has synthesized a molecule that finds and penetrates prostate cancer cells and has created imaging agents and therapeutic drugs that can link to the molecule and be carried with it as cargo.

Potential new target for acute myeloid leukemia

Dr. John Dick, Senior Scientist at the Ontario Cancer Institute, the research arm of Princess Margaret Hospital, co-led a multinational team that has developed the first leukemia therapy that targets a protein, CD123, on the surface of cancer stem cells that drive acute myeloid leukemia (AML), which is an aggressive disease with a poor outcome.

MicroRNAs hold promise for treating diseases in blood vessels

A newly discovered mechanism controls whether muscle cells in blood vessels hasten the development of both atherosclerosis and Alzheimer's disease, according to an article published online today in the journal Nature.

Discovery of new gene associated with diabetes

Research led by the German Institute of Human Nutrition (DIfE) has identified a new gene associated with diabetes, together with a mechanism that makes obese mice less susceptible to diabetes.

Poor sleep may be more dangerous for women than men

Women who get less than the recommended eight hours sleep a night are at higher risk of heart disease and heart-related problems than men with the same sleeping patterns.

Biological warfare in bacteria offers hope for new antibiotics

Scientists are to study a group of proteins that are highly effective at killing bacteria and which could hold the key to developing new types of antibiotics.

Researchers using microRNA to identify aggressive melanoma

Research at the University of Leicester will be breaking new ground in the search for a simple blood test that could tell whether a patient with melanoma has the condition in an aggressive form.

New pieces in the autism inheritance puzzle

Pieces in the complex autism inheritance puzzle are emerging in the latest study from a research team including geneticists from the University of Pennsylvania School of Medicine and The Children's Hospital of Philadelphia (CHOP). The study identified 27 different genetic regions where rare copy number variations - missing or extra copies of DNA segments - were found in the genes of children with autism spectrum disorders, but not in the healthy controls. The findings are published June 26 in the open-access journal PLoS Genetics.

Discovery of a genetic link to risk of kidney stones and osteoporosis

A discovery by scientists at deCODE genetics and academic colleagues from Iceland, the Netherlands and Denmark has pointed to a common biological mechanism contributing to both kidney stones and decreased bone mineral density (BMD).

Australian swine flu vaccine ready in months

A vaccine developed 'in record time' by Australian scientists to protect against the influenza A H1N1 virus (swine flu) may not be available just yet because this swine flu vaccine, developed by University of Queensland (UQ) scientists, is not yet registered for use in Australia.

New understanding of how cells cover gaps

Researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, came a step closer to understanding how cells close gaps not only during embryonic development but also during wound healing. Their study, published this week in the journal Cell, uncovers a fundamental misconception in the previous explanation for a developmental process called dorsal closure.

'Trojan horse' cancer therapy beats tumours resistant to chemotherapy

A new therapy to treat cancer has been developed by Australian scientists and it promises to have far fewer unpleasant side effects than conventional treatments and should also be much cheaper.

Inhaled growth hormone safe for children deficient in this key protein

A multi-center clinical trial led by a Riley Hospital for Children endocrinologist has found that inhaled growth hormone (GH) is well tolerated by children with GH deficiency and that this easy-to-use method can, over a one-week period, safely deliver GH to the blood stream. In addition to having implications for those who need GH, this first pediatric study of administering it through the lungs may also help researchers interested in using this convenient method for effectively delivering other types of medications to children.

Discovery of novel mechanism that could be targeted to prevent cancer spread

Researchers have discovered a key to the function of a specific protein that helps control the levels of other critical proteins within cells, including a protein that suppresses the spread of cancer. The new information about the mechanism of action of the protein, called gp78, may enable researchers to explore new types of therapies to prevent the spread of cancer. The study, by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, was published in the June 26, 2009, issue of Molecular Cell.

Nanofluidic biopsy detects subtle changes in cancer cells

By taking two standard laboratory techniques - capillary electrophoresis and antibody-based protein detection - and shrinking them to the nanoscale, researchers at the Stanford University School of Medicine have created a new method for detecting miniscule changes in the levels of proteins associated with cancer.
