Study IDs Protein That Inhibits HIV From Growing In Cell Cultures

...ls, that HIV grows in and ultimately destroys. HIV attaches to this T-cell by first landing on a receptor called CD4. Once it reacts with the receptor, HIV can enter the cell, multiply and destroy the T-cell, thereby causing immune deficiency. "People with GBV-C have a slower rate of destruction of these T-...

A Safe Drug For Safe Delivery

...by as a rule the placenta (a temporary organ which attaches a fetus to its mother while yet in the womb) is also expelled through the birth canal, following which the uterus(womb) begins to contract gradually, thereby compressing the blood vessels in its muscles. In the event of a tear or trauma during deli...

Insight Into Tanning Process Suggests Novel Way to Prevent Skin Cancer

...n), causing them to produce and secrete MSH, which attaches to adjacent melanocytes and starts the pigment-making process. While Fisher's model adequately explains why redheads do not tan, it isn't the only possibility. "Suppose that during the embryonic or fetal period MC1R never activated cAMP production ...

Molecule responsible for age associated macular degeneration identified

...nd that the molecule, Carboxyethylpyrroles (CEPs), attaches to proteins found in the eye, triggering the uncontrolled growth of blood cells. The Case researchers teamed up with Quteba Ebrahem Jonathan Sears, Amit Vasanji, John Crabb and Bela Anand-Apte and Xiaorong Gu (a Salomon group alumna), of Cleveland ...

Region in the brain in-charge of face recognition includes object recognition as well.

...zes faces and objects. To understand how the brain attaches meaning to a visual scene, scientists need to study both fine- and large-scale brain activity patterns. Second, it may be that what makes one individual exceptional in recognizing faces and another face blind are fine-scale differences in their brain...

Fimbriae Help Bacteria Stick Around Inside the Body

...rland have been studying how the bacterium E. coli attaches to mucous membranes in the body. In their previous research, they explained how the protrusions, known as fimbriae have an adhesive protein called FimH at their tip that binds in an unusual way to a sugar molecule on a surface. The FimH-sugar comb...

Malarial Parasite Hides In Placenta

...have suggested that each protein from the parasite attaches to only one specific protein, a receptor, in the placenta. Ms Rasti and her colleagues suspected, however, that the natural mechanisms are more complex than laboratory studies have shown. They therefore collected and analysed placentas on site in Uga...

Inhibitor That Blocks Host Receptors Found To be Effective In Treating Anthrax

...that blocks the host receptors where anthrax toxin attaches in the body. The researchers said that the inhibitor was able to bind to multiple sites on the host receptor making it much for potent than the inhibitors that binds to single site. The researchers found that the new approach led to a 50,000-fold i...

Elusive Step In DNA Mutation Uncovered By Researchers

... the water molecule with one of its hydrogen atoms attaches to the C8 carbon atom. At the same time, the other proton of the water molecule connects the oxygen atom to that of a neighboring water molecule. This hydrogen bond elongates, leading to the formation of a transition state complex involving the two n...

Researcher Hits Bulls-Eye for Antibiotic Target

...l bonding that keeps it attached. Once the protein attaches to the substrate, it doesn't come off. The protein chews away until it reaches the end of the substrate chain." Sanders worked with a team to create the first-of-its-kind animated movie showing this process from the point of view of the substrate. ...

A Major Break Through in Treatment for Metabolic Syndrome

...raction," says Dr. Wagner. Finding a molecule that attaches to and inhibits the flexible tail of SREBP is unlikely, but a search for inhibitors to fit the grooved KIX site looks much more promising. The team is already initiating high-throughput screening at Harvard Medical School's Institute of Chemistry a...

Endometriosis Could be Treated with Iron Therapy

...etrial tissue developing outside the uterus, which attaches to ligaments and organs in the abdomen. As a result there is often pain, bleeding, inflammation, infertility and adhesions. About 10 percent of women may be affected by this disease. Belgian researchers have concluded from their study with mice tha...

China Nominates Margaret Chan to Run for WHO Director-General's Post

...er in international cooperation on health. "China attaches great importance to the key role of the WHO and hopes to make greater contributions to the development of world health affairs," Liu was quoted as by Xinhua as saying. He said Chan has profound medical knowledge and rich experience in public health ...

Novel Method Of Attaching Artificial Prosthesis

...the bone, and the porosity of the bone. The tissue attaches in with long fibres, and it is like anchors attaching directly into it," he added. The study was led by Professor Gordon Blunn and Dr Catherine Pendegrass, who looked at ways to avoid infection when attaching artificial prosthesis. The details of t...

Brain Cancer Could be Safely Treated with Radioactive Scorpion Venom

...131). When it enters the bloodstream, the compound attaches to the glioma cells, then the I-131 releases radiation that kills the cell. This compound has enabled an experimental treatment for high-grade gliomas, found in 17,000 people in the US every year and usually causing death in the first year of diagn...

New Multi-Modal Contrast Agents, A Boon For Medical Imaging

...s express particular antigens to which an antibody attaches itself. So, if we put the appropriate glioblastoma antibody on the end of a particle, as it passes through the bloodstream it will attach to the tumor cell.’ In experiments with other types of nanoparticles, Watkin has loaded the particles with ca...

LipB Protein Inhibitors Help To Fight Against TB

... the high-resolution picture it was found how LipB attaches specific fatty acids onto other proteins. Wilmanns said that LipB is a very promising drug target as M. tuberculosis has no backup mechanism that could take over LipB's role. The scientists are now searching for drugs that inhibit the active site and...

Sleep Apnea Patients Benefit from Breathing Mask

...small machine strapped to the patient's torso that attaches to an arm cuff. The cuff automatically inflates and deflates to measure patients' blood pressure. After two weeks, patients who received the real CPAP treatment had significant reductions in blood pressure during the day and night. Nighttime oxygen...

Insulin Crystals Holds Promise In Diabetes research

...n insulin molecule is produced from proinsulin, it attaches to an insulin crystal only in special locations where other insulin molecules have formed right angles, called kinks. Using atomic-force microscopy, they discovered a new mechanism by which insulin molecules attach themselves to crystals to form thes...

Forearm Support Promises Fewer on the Job Injury for Computer Professionals

...he forearm support consists of a padded board that attaches to the front edge of workers desks. The support is placed right under the forearm, positioning computer users' arms in a way that releases tension in the shoulder muscles. They are of great use when employers spend substantial time in front of a co...
