A dual PI3 kinase/mTOR inhibitor reveals emergent efficacy in glioma

Scientists have identified a new molecule that inhibits proliferation of a broad range of lethal malignant glioma cells in vitro and in vivo.

A pericellular collagenase directs the 3-D development of white adipose tissue

In the journal Cell, researchers report the serendipitous discovery that the initial development of fat requires a "remodeling" protein that must first make way for the lipid-laden tissue's growth.

New technique for freezing and preserving genetically enhanced pig embryos

Researchers led by a University of Missouri-Columbia professor of reproductive biotechnology have reported success in freezing and preserving swine embryos that were created by in vitro techniques and that carried modified genetic material.

Brits warned against foreign IVF treatment

British couples considering going abroad for in-vitro fertilisation (IVF) and other types of fertility treatment have been warned against the practice.

Swedish ACI method of cartilage repair gives excellent durability

As the population ages, arthritis will become more prevalent. It would be helpful to know more about the causes and treatments of cartilage wear.

WRN exonuclease structure and molecular mechanism imply an editing role in DNA end processing

A team of scientists from Lawrence Berkeley National Laboratory and the Scripps Research Institute has determined the crystal structure and molecular mechanisms of a key part of WRN, a protein that protects humans from premature aging and cancer.

Imitating nature's scaffolding

A team of researchers at the Institute of Bioengineering and Nanotechnology (IBN) has successfully created artificial fibers with nanometer-sized features that can be used to grow cells and tissue structures.

New test for heart disease

Building on years of research on the way that blood flows through the heart valves, researchers from the California Institute of Technology and Oregon Health Science University have devised a new index for cardiac health based on a simple ultrasound test.

Saccharide complexes improve binding of Pentosanpolysulfate and Heparin to bladder epithelium

Anionic glycosaminoglycans including pentosanpolysulphate (PPS) and heparin show weak or no staining of the bladder epithelium and thus do not bind to human or rabbit bladder epithelium in any appreciable amounts.

First evidence that circulating endothelial microparticles lead to heart valve disease

Under normal physiological conditions, low levels of microparticles are continually being shed into the blood from the endothelium - the cells that line the inside of blood vessels and some organs -and appear to cause no problems.

Discovery of new human retrovirus

Howard Hughes Medical Institute researchers and their colleagues have discovered a new retrovirus in humans that is closely related to a cancer-causing virus found in mice. Their findings describe the first documented cases of human infection with a retrovirus that is native to rodents.

Ingredient in red peppers inhibits prostate cancer in laboratory studies

Capsaicin is the pungent ingredient in red peppers and is presently used as a topical pain reliever. Now, a new study shows it may be justified to evaluate capsaicin for inhibiting prostate cancer (CaP) in patients.

Pigs help study of links between polycystic ovary syndrome, obesity, cardiovascular disease and diabetes

Despite the exaggerated, wrinkly snout and long, coarse, spiky hair reminiscent of the 1980s television space alien ALF, some very special swine are helping researchers at Purdue and Indiana universities understand human infertility, diabetes and cardiovascular disease.

Transportation of prion protein across the intestinal mucosa of scrapie-susceptible and scrapie-resistant sheep

While newly published research confirms that under laboratory circumstances prion-protein can be absorbed across the gut, it also shows that this is unlikely to occur in real life.

4 Apr 2006

Gene key to infection-fighting immune cells identified

Every time the human body encounters a virus, bacteria or other infectious agent, immune cells called B-lymphocytes multiply in lymph nodes and then swing into action to fight off the intruders.

New evidence questions the simple link between prion proteins and vCJD

While newly published research confirms that under laboratory circumstances prion-protein can be absorbed across the gut, it also shows that this is unlikely to occur in real life.

Horse anti-serum effectively protects H5N1 infected mice

Antibodies against the bird flu virus H5N1, derived from horses, prevent mice infected with H5N1 from dying from the virus.

Innovative sensing tool used to investigate adenosine triposphate release and its role in cystic fibrosis

The ATP study marks the first application of a novel sensing system developed by a research team led by Christine Kranz at the Georgia Institute of Technology.

PR Pharmaceuticals issued U.S. patent covering 2-methoxyestradiol for the treatment of diabetes

The patent which is assigned to the University of Pittsburgh has been exclusively licensed to PRP. The drug, known as PulmoLAR, containing 2ME as active ingredient, is currently developed by PRP for the treatment of pulmonary arterial hypertension (PAH).

HIV reveals another secret to its success

In HIV infection, a protein produced by infected cells penetrates immune B cells, preventing them from producing antibodies that could do the virus real harm.
