Combating Blindness Is Vision Of UT, ORNL Project
Millions of people at risk of becoming blind could one day be helped by an Oak Ridge National Laboratory technology originally intended to understand semiconductor defects. Tadpole Soon To Help In The Fight Against Cancer And Lymphedema
Lymph circulates in our bodies through a complex network of lymphatic vessels, of which little is known. This network is, however, of major importance for the support of the immune system and the fluid in our body. Researchers from VIB are the first to indicate that this network can be studied with the help of tadpoles. This accelerates research of the lymphatic vessel network. Long-term Hormone Use Helps Prostate Cancer Patients Live Longer
Doctors in Canada have discovered that treating high-risk prostate cancer patients with radiation therapy and adding hormone therapy for more than one year allows patients to live longer, have better control of their prostate specific antigen levels and lowers the rate of death specifically from prostate cancer, according to a study published in the November 1, 2005, issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO. Human Ancestors More Primitive That Once Thought
Analysis of the earliest known hominid fossils outside of Africa has revealed that the first human ancestors to inhabit Eurasia were more primitive than previously thought. The fossils, dated to 1.8 million years old, show some modern aspects of lower limb morphology, such as long legs and an arched foot, but retain some primitive aspects of morphology in the shoulder and foot. The species had a small stature and brain size more similar to earlier species found in Africa. Beautiful Birds: Masterpieces From the Hill Ornithology Collection, Co
This site "traces the development of ornithological illustration in the 18th and 19th centuries and highlights the changing techniques —from metal and wood engraving to chromolithography —during that period."Includes an exhibition, timeline of artists and authors, a guide to the ornithological collections at Cornell University libraries, and a bibliography. Searchable. What Immune Cells See: Ins And Outs Of Peptide Processing
Immune cells known as T cells help us clear invading microbes, such as HIV, from our bodies, but they can also cause autoimmunity when they inappropriately attack our own tissues. T cells are activated when a receptor on their surface (the TCR) recognizes a specific complex of a peptide fragment bound to a protein known as an MHC molecule. Media Briefing on Canine Influenza
Transcript of a September 2005 briefing for the media that discusses "the publication of a Science Journal article, 'Transmission of Equine Influenza Virus to Dogs.'"The transcript addresses the transmission of the disease from horses to racing greyhounds and domestic dogs, mortality rate, treatment of the disease, and related matters. From the Centers for Disease Control and Prevention (CDC). River Blindness Parasite Becoming Resistant To Standard Treatment
Recent reports of patients failing to respond to ivermectin, the standard drug for treating river blindness (onchocerciasis), have suggested the emergence of drug-resistant Onchocerca volvulus (the parasite that causes river blindness). According to a new study Ivermectin is causing genetic changes in the parasite. Highly Adaptable Genome In Gut Bacterium Key To Intestinal Health
A bacterium that lives in the human gut adaptively shifts more than a quarter of its genes into high gear when its host's diet changes from sugar to complex carbohydrates. Sea Cucumbers Fast Track Organ Regrowth By Healing Their Wounds
Sea cucumbers are the champions of organ regrowth because they direct their wound healing abilities towards restoring their organs. The discovery that Holothuria glaberrima uses similar cellular mechanisms during wound healing and organ regeneration gives us the opportunity to discover how to repair our own wounds and, perhaps eventually, how to regenerate body parts.
