University Envisages Improvements in Artificial Arm

...-arm amputations. Each of the 100 electrodes would selectively 'listen' or 'talk' to a small number of fibers in a nerve. A prototype of the bionic arm will be available for testing in four years. Source: Eureka Alert...

ROZEREM? Can Be A Better Option For Insomnia Patients

... has a unique therapeutic mechanism of action that selectively targets two receptors located in the brain's suprachiasmatic nucleus (SCN). The SCN is known as the body's "master clock" because it regulates 24-hour, or circadian rhythms, including the sleep-wake cycle. The FDA approved ROZEREM in July 2005 for...

Cholesterol mystery solved through research mice

...uction. In one group of animals, the ABCA1 gene is selectively deleted in the liver – which means their livers cannot produce HDL. It was through studying these mice that the scientists were able to report in 2005 that the liver is likely the body's main source of good cholesterol – producing 70 to 80 percent. ...

Drug Combo Improves Performance Of Multiple Sclerosis Drug

...sease is based on the use of drugs (Copaxone) that selectively inhibits the destruction of myelin. Copaxone treatment however is effective only in about 30- 35% of the cases. The researchers, inspired by results of their first study, set out to explore the effectiveness of the new drug combination, Copaxone- A...

Female Foetus Can Survive More Stress

...ine. According to them, only weak foetuses were selectively targeted by the mother's body, giving more robust males every opportunity to thrive. They also said that actively culling weak male foetuses might increase the overall chance of a woman's genetic line surviving down the generations, as weak individua...

Gene Therapy To Cure Parkinson's Disease

...ons. RNA interference is a sophisticated method to selectively turn off one gene in a cell, leaving others unaffected. 'This is the first step in developing a new therapy for Parkinson's disease based on molecular knowledge of the disease,' said Mohan K. Sapru, research assistant professor of pediatrics, who ...

Little Known DNA Repair Enzyme May Be A Tumor Suppressor Gene

...tions. We are now investigating this hypothesis by selectively deleting the Rev3L gene in adult mouse cells to study how the loss of DNA polymerase zeta influences the development and progression of spontaneous cancers," the researchers explained. This work was supported by a grant from the National Cancer Inst...

Artemisinin May Prevent Breast Cancer

...that the findings had shown that the substance was selectively toxic to cancer cells. “Based on earlier studies, artemisinin is selectively toxic to cancer cells and is effective orally. With the results of this study, it's an attractive ca...

Bio-engineered rice fortified with iron boost women health

... such as rice, maize, wheat, beans and cassava, by selectively breeding to enhance nutritional qualities has merit for reducing micronutrient deficiencies in the developing world," said Haas. The biofortified rice was developed by the International Rice Research Institute (IRRI) in the Philippines. "Now that ...

Ruboxistaurin As A Novel Treatment For Diabetic Nephropathy

...athogenesis of diabetic nephropathy. Ruboxistaurin selectively inhibits protein kinase C-? and ameliorates kidney disease in animal models of diabetes. The study was performed to evaluate the effects of 32mg/day ruboxistaurin for 1 year in persons with type 2 diabetes and persistent albuminuria persistent albu...

Three In One Ultrasound Probe For 3-D Imaging Of Heart And Tissue Destruction Developed

... the heart's interior in three dimensions and then selectively destroy heart tissue with heat to correct arrhythmias.// This is the first time a three in one attempt has been made regarding 3-D imaging, ultrasound and therapy. The researchers believe that the technique may revolutionize the most widely used me...

Prose Memory Deficits Found To Be Associated With Schizophrenia

...rchers have proposed that some forms of memory are selectively impaired in schizophrenia. To understand the nature of contextual verbal memory impairment that may be associated with schizophrenia, researchers from China recently used memory of prose as a medium and studied how the illness differentially affect...

The potent anti-leukemia activity of Berbamine

..., berbamine from plant Berberis amurensis that can selectively induce cell death of both Gleevec-sensitive and -resistant Ph+ CML cells. Importantly, the results in this study show that berbamine is also active against Gleevec-resistant leukemia cells. It is of interest to note that berbamine down-regulates p2...

Ambiguous Efficacy Of Opioid Drugs In Chronic Inflammatory Joint Pain Relief

...s, appear to be highly sensitized to endomorphins, selectively drawing the natural analgesic to their target spots throughout the peripheral tissue of joints. Recently a study, published in the October issue of Arthritis and Rheumatism, was conducted to determine whether peripheral administration of the endogen...

Gold Nanoparticles: Agents For Noninvasive Cancer Therapy

...iency of gold nanospheres as photothermal agent by selectively delivering gold nanoparticles to oral carcinoma cells that overexpress EGFR, a clinically related cancer biomarker, and discuss the potential of using this selective technique in molecularly targeted photothermal therapy. In the study, two oral squa...

New Ways To Treat Vascular Birthmarks

... the most effective treatment, with its ability to selectively target blood vessels. Other scientists had reviewed the natural course, classification and history of treatment of these lesions throughout the past 100 years. Observation may be all that is necessary for stable lesions, the authors suggest, but su...

Nanocells cancer combination therapy acts as chemotherapy as well as anti-angiogenic drug

...ood vessels in the tumour and the normal organs to selectively deliver the drugs. Once inside the tumour, the nanocell's outer balloon disintegrates and the anti-angiogenesis drug brings about the blood vessel collapse, shrinkage and shut down. The chemotherapy drugs in the inner balloon are then released slow...
