DURHAM, N.C. – Deft molecular detective work at Duke University Medical Center suggests that scientists may soon be able to resurrect niacin as one of the best and cheapest ways to manage cholesterol.
Niacin, also known as nicotinic acid or vitamin B3, has long been regarded as one of the most effective weapons in managing cholesterol. It can lower levels of triglycerides, fatty acids and to a lesser extent, the "bad" kind of cholesterol (LDL) while at the same time powerfully increasing the "good" kind (HDL). But there's a catch – a big one. Patients don't like to take niacin because in…
Smokers who do not want to quit right now but would like to at least reduce their smoking are twice as likely to stop smoking in the long-term if they use nicotine replacement therapy (NRT) to help them cut down gradually, according to research published on bmj.com.
The research is the first of its kind to focus on sustained smoking abstinence using NRT for smokers who have no immediate plans to stop smoking.
Smoking is one of the greatest causes of illness and premature death in the world. Half of UK smokers try to stop every year but only 2-3% of them succeed. One of the reasons for…
Carbohydrates are tough molecules to build because of their complicated, branched structure. So instead of trying to build carbohydrates from scratch, scientists today use molecules isolated from nature, a painstaking process that could take months.
Speaking at the ACS meeting in Salt Lake City, Peter H. Seeberger, Ph.D., described development of an automated carbohydrate synthesizer, a device that builds these intricate molecules in a few hours — rather than the months or years required with existing technology.
Scientists trying to synthesize DNA and protein-based molecules experienced a…
Tobacco isn't exactly famous for its health benefits, though the mental health effect of a Fonseca and a port after a nice steak is well-documented, but now scientists have succeeded in using genetically modified tobacco plants to produce medicines for several autoimmune and inflammatory diseases, including diabetes.
A large team of scientists from several European research organizations have participated in the study as part of the Pharma-Planta project (http://www.pharma-planta.org/), led by Professor Mario Pezzotti at the University of Verona. They set out to create transgenic…
The increasing frequency of bacterial resistance to antibiotics is alarming. Researchers from the Albert Einstein College of Medicine of Yeshiva University believe they may have found a solution to this seemingly losing battle. Professor Vern L. Schramm and team have developed antibiotic compounds that do not lead to microbial resistance over time.
Administered antibiotics initially work extremely well, killing more than 99.9% of the microbes they target. However, microbes have a high rate of mutation and because antibiotics are initially designed for a single specific…

Shire plc today announces the Japanese launch of FOSRENOL(R) (lanthanum carbonate), which is now available to prescribers and patients in Japan through Shire's strategic alliance partner Bayer Yakuhin Ltd.
FOSRENOL is the first commercially available non-calcium, non-resin phosphate binder in Japan and is used in the control of hyperphosphataemia in chronic renal failure patients on dialysis.
Bayer Yakuhin received an exclusive license from Shire in December 2003 to develop FOSRENOL in Japan, completing Phase II and Phase III clinical trials in the Japanese population.
Studies based on…
Most people consume far too much salt, and a University of Iowa researcher has discovered one potential reason we crave it: it might put us in a better mood.
UI psychologist Kim Johnson and colleagues found in their research that when rats are deficient in sodium chloride, common table salt, they shy away from activities they normally enjoy, like drinking a sugary substance or pressing a bar that stimulates a pleasant sensation in their brains.
"Things that normally would be pleasurable for rats didn't elicit the same degree of relish, which leads us to believe that a salt deficit and the…
Ecstasy may help suffers of post-traumatic stress learn to deal with their memories more effectively by encouraging a feeling of safety, says new research.
Studies have shown that a type of psychological treatment called exposure therapy – where the patient repeatedly recalls the traumatic experience or is repeatedly exposed to situations that are safe but still trigger their traumatic feelings – can be effective in relieving stress responses in patients with post-traumatic stress disorder (PTSD) and other anxious conditions. The therapy works by helping the patient to re-learn the…
Revered in India as "holy powder", the marigold-colored spice known as turmeric has been used for centuries to treat wounds, infections and other health problems. In recent years, research into the healing powers of turmeric's main ingredient, curcumin, has increased as scientists have examined claims of antioxidant, anti-cancer, antibiotic, antiviral and other properties, though little has been learned about exactly how curcumin works inside the body.
University of Michigan researchers led by Ayyalusamy Ramamoorthy now say that curcumin acts as a disciplinarian, inserting itself into cell…
Two highly lethal viruses that have emerged in recent outbreaks are susceptible to chloroquine, an established drug used to prevent and treat malaria, according to a new basic science study by researchers at Weill Cornell Medical College in the Journal of Virology.
The two henipaviruses that are the subject of the study -- Hendra Virus (HeV) and Nipah Virus (NiV) -- emerged during the 1990s in Australia and Southeast Asia. Harbored by fruit bats, they cause potentially fatal encephalitis and respiratory disease in humans, with a devastating 75 percent fatality rate. More recently, NiV…
