Blue-green algae linked to Alzheimer's disease

An international team of researchers, including scientists from the University of Dundee have announced that cyanobacteria (blue-green algae) found throughout the world may produce a toxin linked to certain types of neurological disease.

Scientist finds different paths lead to similar cognitive abilities

Despite the divergent evolutionary paths of dolphins and primates -- and their vastly different brains -- both have developed similar high-level cognitive abilities, says Emory University neuroscientist and behavioral biologist Lori Marino.

Genetic testing could bolster radiotherapy's effectiveness against cancer

Obtaining a genetic picture of how a tumor will react to the many treatment techniques available could help doctors prescribe therapies customized for individual cancer patients' needs, suggests a Purdue University research team.

Seven-year research project to expand the evidence base in dentistry

Washington Dental Service, the University of Washington School of Dentistry and the School of Dentistry at Oregon Health Sciences University are partnering in a seven-year research project to expand the evidence base in dentistry.

Researchers have identified a new clinical syndrome

Researchers have identified a new clinical syndrome that produces serious and sometimes fatal symptoms in a variety of seemingly unrelated diseases. The syndrome, described in the April 6 issue of the Journal of the American Medical Association, is caused by hemolysis, the destruction of red blood cells.

Vitamin E supplements speed up the development of latent cancers

Taking high-dose vitamin E supplements for an extended period doesn't protect against cancer; in fact, it may even speed up the development of latent cancers, according to a study by researchers from Hotel-Dieu de Quebec Research Centre and Universite Laval. Their results are published in the April issue of the prestigious Journal of the National Cancer Institute.

How heart is formed in the embryo helps explain congenital heart disease

Children's Hospital of Pittsburgh Cardiologist Bradley B. Keller, MD, and his research team are discovering details in the lab that explain how the heart is formed in the embryo. This knowledge improves the chances of doctors identifying fetuses who can benefit from intervention to treat congenital defects.

Metabolic side effects of antipsychotics are known, but rarely monitored

Psychiatrists are doing a “modest” job of monitoring for weight gain, diabetes and other metabolic problems that may result from use of the newer antipsychotics for schizophrenia, researchers say.

Potential therapeutic target for infertility and contraception

The multiple “litter” births of mice, versus the normal singleton pregnancy of humans, is due to defective processing in mice of a common mammalian protein called bone morphogenetic protein 15 (BMP-15), according to new research from the University of California, San Diego (UCSD) School of Medicine.

Sildenafil prevents anti-cancer drug induced heart damage

Virginia Commonwealth University researchers have found that the popular impotence drug Viagra prevents damage to the heart from a potent chemotherapeutic agent frequently used in the treatment of breast cancer, leukemia and sarcomas.

Method of gene therapy accurately corrects mutations in disease-causing genes

Harnessing the strength of a natural process that repairs damage to the human genome, a researcher from UT Southwestern Medical Center has helped establish a method of gene therapy that can accurately and permanently correct mutations in disease-causing genes.

Promising new therapy that prompts the immune system to aid in the fight against melanoma tumors

Melanoma is a particularly deadly form of skin cancer very resistant to treatment. Researchers at H. Lee Moffitt Cancer Center & Research Institute and the University of South Florida are testing a promising new therapy that prompts the immune system to aid in the fight against melanoma tumors.

Pair of cancer genes found to drive both cell migration and division

Johns Hopkins researchers have found that two genes already known to control cell movement are also needed for proper cell division. They report their findings in the April issue of Developmental Cell.

DNA repair kit announced by scientists

A study by scientists at Sangamo BioSciences, Inc. has demonstrated the use of the Company's zinc finger DNA-binding protein (ZFP) technology to achieve highly efficient, permanent correction of a disease-causing gene in primary human cells.

Parents fail to set the rules on smoking

A study involving 1,770 parents and guardians in New York and New Jersey has found that despite repeated health warnings about the dangers of second-hand smoke, a large percentage of families have no rules that limit children's exposure to tobacco smoke.

New report shows therapy as effective as drugs for depression

In a surprising report from the University of Pennsylvania, researchers are suggesting that, contrary to current American Psychiatric Association (APA) guidelines, psychological therapy and counselling can be just as effective as drugs in the early stages of treating moderate to severe depression.

Men have a four times greater risk than women of developing abdominal aortic aneurysms

Men have a four times greater risk than women of developing abdominal aortic aneurysms, estimated to be the cause of death in 4 percent of people over the age of 65, but the mechanism for this higher incidence has remained unknown.

Alteration of steroid receptor genes creates fat burning muscle

The Salk Institute scientist who earlier discovered that enhancing the function of a single protein produced a mouse with an innate resistance to weight gain and the ability to run a mile without stopping has found new evidence that this protein and a related protein play central roles in the body's complex journey to obesity and offer a new and specific metabolic approach to the treatment of obesity related disease such as Syndrome X (insulin resistance, hyperlipidemia and atherosclerosis).
