Vitamin D and immune defenses
Mon, 08 Mar 2010 15:29:14 GMT
Researchers at the University of Copenhagen have discovered that Vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin, the killer cells of the immune system T cells - will not be able to react to and fight off serious infections in the body. For T cells to detect and kill foreign pathogens such as clumps of bacteria or viruses, the cells must first be 'triggered' into action and 'transform' from inactive and harmless immune cells into killer cells that are primed to seek out and destroy all traces of a foreign pathogen........

Antibodies linked to cardiovascular disease
Mon, 08 Mar 2010 15:29:14 GMT
A study by scientists in Australia and the United Kingdom suggests that autoantibodies to fat binding proteins significantly increase in systemic lupus erythematosus (SLE) patients with active disease. This increase in anti-apolipoprotein (anti-Apo A-I), anti-high-density lipoprotein (anti-HDL), and anti-C-reactive protein (anti-CRP) may contribute to the development of atherosclerosis in SLE patients, placing them at risk for cardiovascular disease (CVD). Complete findings of this study are available in the recent issue of Arthritis and Rheumatism, published by Wiley-Blackwell on behalf of the American College of Rheumatology........

Key interaction that controls telomeres
Mon, 08 Mar 2010 15:29:14 GMT
In the dominoes that make up human cells, scientists at the University of Michigan Comprehensive Cancer Center have traced another step of the process that stops cells from becoming malignant. It starts with the enzyme telomerase, which affects the caps, or telomeres, at the end of a chromosome. Telomeres shorten over time. But telomerase prevents this from happening, making the cell immortal. If cancer is triggered in the cell, the presence of telomerase leads to the growth of the cancer........

Genetic variant linked to biological aging
Mon, 08 Mar 2010 15:29:14 GMT
Researchers announced recently (7 Feb) they have identified for the first time definitive variants linked to biological ageing in humans. The team analyzed more than 500,000 genetic variations across the entire human genome to identify the variants which are located near a gene called TERC. The study in Nature Genetics published recently by scientists from the University of Leicester and King's College London, working with University of Groningen in the Netherlands, was funded by The Wellcome Trust and the British Heart Foundation........

Clean, biodegradable structure for stem cell growth
Mon, 08 Mar 2010 15:29:14 GMT
Medical scientists were shocked to discover that virtually all human embryonic stem cell lines being used in 2005 were contaminated. Animal byproducts used to line Petri dishes had left traces on the human cells. If those cells had been implanted in a human body they likely would have been rejected by the patient's immune system........

Early detection of Alzheimer's disease
Mon, 08 Mar 2010 15:29:14 GMT
Investigators from the International Center for Biomedicine and the University of Chile, in collaboration with the Center for Bioinformatics of the Universidad de Talca, have discovered that two drugs, the benzimidazole derivatives lanzoprazole and astemizole, appears to be suitable for use as PET (positron emission tomography) radiotracers and enable imaging for the early detection of Alzheimer's Disease. The study is reported in the current issue of the Journal of Alzheimer's Disease.......

New computational tool for cancer treatment
Mon, 08 Mar 2010 15:29:14 GMT
A number of human tumors express indoleamine 2,3-dioxygenase (IDO), an enzyme which mediates an immune-escape in several cancer types. Scientists in the Molecular Modeling group at the SIB Swiss Institute of Bioinformatics and Dr. Benot J. Van den Eynde's group at the Ludwig Institute for Cancer Research Ltd (LICR) Brussels Branch developed an approach for creating new IDO inhibitors by computer-assisted structure-based drug design. The study was presented in the January 2010 online issue of the Journal of Medicinal Chemistry.......

HIV researchers solve key puzzle
Mon, 08 Mar 2010 15:29:14 GMT
Scientists have made a breakthrough in HIV research that had eluded researchers for over 20 years, potentially leading to better therapys for HIV, as per a research findings published recently in the journal Nature The researchers, from Imperial College London and Harvard University, have grown a crystal that reveals the structure of an enzyme called integrase, which is found in retroviruses like HIV. When HIV infects someone, it uses integrase to paste a copy of its genetic information into their DNA........

Stopping Schizophrenia Before It Starts?
Mon, 08 Mar 2010 15:29:14 GMT
The onset of schizophrenia is not easy to predict. Eventhough it is linked to as a number of as 14 genes in the human genome, the previous presence of schizophrenia in the family is not enough to determine whether one will succumb to the mind-altering condition. The disease also has a significant environmental link........

Older brains make good use of 'useless' information
Mon, 08 Mar 2010 15:29:14 GMT
Toronto A newly released study has observed promising evidence that the older brain's weakened ability to filter out irrelevant information may actually give aging adults a memory advantage over their younger counterparts. A long line of research has already shown that aging is linked to a decreased ability to tune out irrelevant information. Now researchers at Baycrest's world-renowned Rotman Research Institute have demonstrated that when elderly adults "hyper-encode" extraneous information and they typically do this without even knowing they're doing it they have the unique ability to "hyper-bind" the information; essentially tie it to other information that is appearing at the same time........
