Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers
A new study investigating the respiratory system of insects may have solved a mystery that has intrigued physiologists for decades: why insects routinely stop breathing for minutes at a time. Challenging previous theories, researchers at UC Irvine and Humboldt University propose that insects such as grasshoppers, moths, butterflies, some types of fruit flies, beetles and bugs close off th...Bone Density Recovers After Teens Stop Injected Contraceptive
Lower bone density appears to recover in adolescent females once they stop using the injected contraceptive depot medroxyprogesterone acetate (DMPA), according to a study funded by the National Institute of Child Health and Human Development of the National Institutes of Health. Previous studies had shown that women who use DMPA, marketed under the brand name Depo-Provera, experience a lo...Protein offers way to stop microscopic parasites in their tracks
Scientists may have found a way to throw a wrench in the transmissions of several speed demons of the parasite world. Researchers at Washington University School of Medicine in St. Louis and Harvard University have identified a protein that could help them develop drugs to stop or slow cell invasion by malaria and other parasites known as apicomplexans. Results of the study will appear in...Stopping smallpox in its tracks: A new anti-viral approach
Natural or deliberate exposure to smallpox poses a great health threat, especially since routine smallpox vaccinations have been discontinued and no clinically approved treatment currently exists. In the February 1 issue of the Journal of Clinical Investigation, Ellis Reinherz and colleagues from Harvard Medical School propose a new antiviral therapy ?a low molecular weight inhibitor of signaling...To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists
A team of scientists at The Scripps Research Institute and the University of Wisconsin have demonstrated a new way of fighting antibiotic resistance: by stopping evolution. In the June issue of the open-access journal PloS Biology, the team describes how a protein called LexA in the bacterium Escherichia coli promotes mutations and helps the pathogen evolve resistance to antibiotics. The...Pyrex brand low actinic narrow mouth Erlenmeyer flask, Pyrex ST 27 stopper from Sigma-Aldrich

Controlling pain in patients following surgeries has been effectively taken care of by a new therapy called distraction therapy. Doctors at the Johns Hopkins Medical Institutions in the US have distracted patients with images and sounds from nature and have successfully controlled pain in patients following a painful procedure called bronchoscopy, which involves inserting the tube into t...Quitting smoking stops lung decline
Quitting smoking for a year at a time can keep lungs from deteriorating and reduce the risk of death, according to American researchers. At the University of Ohahio, Dr.Margit Pelkon and collegues investigated the effects of quitting smoking. They studied more than 1,000 Finnish participants in four groups:// those who had never smoked, those who had quit permanently, those who had qui...Prescription Drug - Helps People Stop Smoking
The Mumbai-based Sun Pharmaceutical Industries entered the antismoking segment with its "Smoquit" (buproprion 150mg tabs) recently. The medication in Smoquit has been used for over a decade as an antidepressant, albeit at a different dose. The Rs. 13.50-per tablet priced Smoquit, the first pharmacotherapy ever available for the treatment of smoking problem, is a prescription drug and is r...Blindness can be stopped with drug for acne treatment
Stargardt's macular degeneration, also called juvenile macular degeneration, is an inherited disease which affects one in 10,000 people. This condition results from a defect in the ABCR gene, which is responsible for coding for a protein that removes all-trans-retinaldehyde, a vision byproduct, from retinal rods and cones. Rods and cones are supported by retinal-pigmented epithelium (RPE...Therapy for stopping the spread of cancer cells
An enzyme that affects the spread of cancer cells could provide a new target for therapy, say researchers in the US. Cancer cells spread through the body by hanging on to carbohydrate molecules on other, normal cells, and then letting go and moving on to the next cell. The composition of carbohydrates on the cells affects the balance between hanging on to neighbouring cells and letting go...Koch Stop and Chop Manipulator
