Stem cell research that could help diabetics

University of Florida adult stem cell experts have restored normal blood sugar levels in diabetic mice for three months by chemically coaxing bone marrow cells to produce insulin, a hormone normally made in the pancreas.

New computer program accurately estimates chance of developing breast cancer

CANCER Research UK scientists have devised a user-friendly computer program, called the IBIS risk evaluator, which can give the most accurate estimate yet of a woman's chance of developing breast cancer.

Tiny Ribozyme package could be future treatment of Hepatitis B virus

Penn State College of Medicine researchers have developed a tiny package that searches for and destroys up to 80 percent of hepatitis B virus in the livers of mice.

Researchers discover new form of the Rett syndrome protein

Adrian Bird and Skirmantas Kriaucionis of the University of Edinburgh have discovered a novel form of the protein MeCP2. This alternate form, coined MeCP2 alpha, differs from the original only in the first 19 amino acids. Interestingly, Adrian Bird, Director of the Welcome Trust Centre for Cell Biology at Edinburgh University, found that MeCP2 alpha, is ten times more prevalent not only in the brain but also in other tissues. These findings are currently reported online in Nucleic Acids Research. Similar findings were reported yesterday in Nature Genetics online by Berge Minassian, a neurologist and scientist at Toronto's Hospital for Sick Children.

Clinical study - Diagnostic testing for epilepsy released

Bionomics Limited announced today the publication of its international clinical study involving patients with a form of epilepsy confined to early childhood in the scientific journal, Annals of Neurology. The publication details genes associated with a condition known as Benign Familial Neonatal Infantile Spasms (BFNIS), a condition in which infants experience seizures in the first few months of their life.

Scientists identify genetic changes during infection by tuberculosis

Researchers at the Center for Biomedical Inventions at UT Southwestern Medical Center at Dallas have identified the genetic changes that Mycobacterium tuberculosis, the bacterium that causes tuberculosis, undergoes during infection of a living host.

New research may help treatment of Norrie disease and familial exudative vitreoretinopathy (FEVR)

Researchers have discovered that genetic mutations underlying two inherited eye disorders arise in different components of a single intracellular signaling pathway that is responsible for development of blood vessels in the eye.

New pill for post-traumatic stress disorder

Every day, people suffer traumatic experiences that scar their minds. Combat, rape, bombings, burns, beatings, and horrific car accidents haunt them with memories impossible to suppress. Such day- and nightmares are part of a problem known as post-traumatic stress disorder, or PTSD.

Breast feeding increases choline which means more brain cells

Five years ago, University of North Carolina at Chapel Hill researchers first reported finding that the nutrient choline played a critical role in memory and brain function by positively affecting the brain’s physical development. Differences in development influenced action, the scientists and their colleagues found. In animal experiments conducted at Duke University, both young and old rats performed significantly better on memory tasks if they received enough choline before birth compared with same-age rats whose mothers were fed choline-deficient diets. The latter showed deficits in the hippocampus and septums of their brains.

Research provides better understanding of lipodystrophies disorders

More than a decade of work conducted by UT Southwestern Medical Center at Dallas researchers has led to a better understanding of the underlying causes of lipodystrophies - disorders characterized by the selective loss of fat tissues, resulting in metabolic complications, such as severe diabetes and high blood cholesterol levels.

AMT Obtains Orphan Drug Designation for Its LPL Gene Therapy Product

AMT today announced that its adeno-associated viral vector (AAV) expressing lipoprotein lipase (LPL) product has been designated as an orphan medicinal product for the treatment of LPL deficiency by the European Commission. This decision follows a positive recommendation by the European Agency for the Evaluation of Medicinal Products.

Fruits and vegetables promote stronger bones in girls

Although calcium usually gets top billing when it comes to bone health, fruits and vegetables may also promote stronger bones in girls, new study findings suggest.

Government, industry, and academia focus on obesity

Amid shifting scientific data on nutrition and obesity, experts from government, industry, and academia converged on Harvard Medical School last week to discuss obesity's causes and how to craft a coherent public nutritional message.

New therapies that may treat cancers

Scientists at the Johns Hopkins Kimmel Cancer Center and Howard Hughes Medical Institute have found mutations in a gene linked to the progression of colon and other cancers. The research findings, may lead to new therapies and diagnostic tests that target this gene.

Researchers find link that could aid in treatment of kidney cyst diseases

Researchers at UT Southwestern Medical Center at Dallas have uncovered a link between two cyst-forming diseases that affect the kidneys, a finding that could lead to treatments for both a rare form of diabetes and a common kidney disease.

Treatment for ovarian cancer by gene targeting

Targeting and inactivating a key gene could be a subtle and effective treatment for certain types of ovarian cancer, Scottish researchers suggest in a study published in Clinical Cancer Research.

Scientists identify blood development gene which may aid the fight against cancer and leukemia

Researchers at Harvard-affiliated Dana-Farber Cancer Institute have pinpointed a crucial gene on which the normal development of the body's entire blood system depends. If the gene is absent, even the most basic blood stem cells cannot be generated. In a mutated form, this gene can cause a rare and devastating form of leukemia.

New Theory About Alzheimer's Disease

A group of scientists at The Scripps Research Institute has proposed a new theory about the cause of Alzheimer's disease, the progressive neurodegenerative disorder that currently afflicts some 4.5 million Americans. According to the hypothesis, the disease arises as a consequence of inflammation, which creates abnormal metabolites out of normal brain molecules.

Drug Based on Brain Chemical Could End Narcolepsy and Insomnia

Researchers at UT Southwestern Medical Center at Dallas have discovered a potentially new avenue for treating human narcolepsy, and the work may also lead to more effective ways for insomniacs to boost their wakefulness during the daytime.

Gene Responsible for The Most Common Form of Diabetes

International research teams studying two distinct populations have found variants in a gene that may predispose people to type 2 diabetes, the most common form of the disease. The researchers, who collaborated extensively in their work, report their findings in companion articles in the April issue of Diabetes.
