Anti-blood clotting OJ from University of Liverpool

An anti-blood clotting drink has been developed by an up-and-coming biotechnology business based at the University of Liverpool’s Business Incubator, MerseyBIO. Provexis, a medical food company, is in the final stages of its large-scale trial on the new orange juice drink that has been shown to lower the chance of blood clots and thereby reduce risk of heart attack, stroke and the development of deep vein thrombosis.

Enzyme Acetylcholinesterase (AChE), New Approach to Drug Design

French and American researchers have developed a unique approach to drug design where an important neuron-signaling enzyme called acetylcholinesterase (AChE) acts as a microscopic vessel filled with reactant chemicals, to create its own, tailored therapeutic agent.

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.

Decreased collagen may make women more susceptible to pelvic organ prolapse

Decreased collagen levels might make some women more susceptible to pelvic organ prolapse and urinary incontinence, according to a new study by physicians at Temple University School of Medicine and Temple University Hospital. The study, “Collagen content of nonsupport tissue in pelvic organ prolapse and stress urinary incontinence,” appears in a recent issue of the American Journal of Obstetrics and Gynecology.

DNA repair enzymes to fight cancer

The body has a set of DNA repair enzymes that clean up damage to the genome, to reduce potential problems. Many commonly used cancer chemotherapies work by alkylating DNA. However, the DNA repair enzymes are just as capable of repairing this alkylation as if it were damage from any other source, and so they act to overcome the effects of the therapy, reducing its effectiveness.

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.

Raptiva, 20 percent improvement in an individual's signs and symptoms of arthritis.

Genentech, Inc. and XOMA Ltd. today announced preliminary results of a randomized, placebo-controlled Phase II study with RAPTIVA™ (efalizumab) in 107 patients with psoriatic arthritis. The study did not reach statistical significance at 12 weeks (84 days) for the primary endpoint, ACR 20 response. An ACR 20 response indicates at least a 20 percent improvement in an individual's signs and symptoms of arthritis.

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.

Plasticiser Phthalates connected with rising infertility rates

Phthalates, largely used as plasticisers, have long been suspected in connection with rising infertility rates, particularly among men. These substances are quite common and are considered highly hazardous to human health because they disrupt the hormonal balance and impair reproduction and development. What has not been clear up to now is the amount of phthalates that enter the human body.

Study suggests cigarette smoking increases likelihood of death by prostate cancer

Although cure rates for prostate cancer patients who smoke cigarettes are about the same as patients who do not smoke, researchers have found that smokers were more likely to die of other causes than non-smokers, according to a new study in the March 15, 2004, issue of the International Journal of Radiation Oncology•Biology•Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.

The placebo effect, study suggest pain management is possible

A Columbia professor has uncovered fresh evidence of the existence of the often-debated placebo effect. Even the professor himself, Tor D. Wager, of the Department of Psychology, was surprised by his team's findings. The study showed that the human brain processes pain differently when people believe that they have been given a pain-relieving skin cream. Wager, lead author of the study, defines "placebo" as a treatment that has no direct pharmacological effect and that may influence one's experience and physiology through one's beliefs.

New Treatment for Chronic Head Pain

Dr. Levy pioneered a procedure known as supraorbital nerve stimulation or SOS, in which neurotransmitters are implanted into the forehead to block head pain. Tiny wires are burrowed under the skin until the precise location of pain is marked by a tingling response to electrical charge. The wires are kept in place for a week, and if pain is lessened and the patient is comfortable with the technology, neurotransmitters are surgically implanted under local anesthesia. The patient is able to control pain relief by manually adjusting the level of electrical stimulation through a hand held device.
