HIV-1's high virulence might be an accident of evolution

...plication and transmission, while at the same time preventing escalation of immune activation to levels that may be harmful to the host," the researchers said. The results also raise the possibility that treatments that could carefully limit the immune system in infected humans--mimicking the tight balance mai...

Microbes transform 'safest' PBDEs into more harmful compounds

...toms called bromines that sap oxygen from the air, preventing a fire. Over time, PBDE’s can leach into the air, soil and sediment, and move up through the food chain. These compounds have been detected in fruits and vegetables, meats, dairy products and even household dust. The American Chemical Society ?the w...

Study shows pine bark naturally decreases severe chronic venous insufficiency

..., the increased pressure on veins gets normalized, preventing the veins from further increasing in size. "Pycnogenol® has demonstrated its efficacy and safety in several clinical trials and symptoms of CVI have been reduced significantly by Pycnogenol® in controlled studies. We were pleased to see that not on...

Gene therapy injected into the brains' of mice with Huntington's disease

... The authors wrote "Although GDNF's exact role in preventing cell death in mice modeled with HD remains to be established, we speculate the increase trophic support and inhibiting apoptosis (programmed cell death) via these two pathways likely played integral roles." Kordower says the study suggests a new app...

Researcher gives hard thoughts on soft inheritance

...leave DNA sequence unaltered but can affect DNA by preventing the expression of genes. Richards cites a study that shows certain epigenetic alleles can be inherited that affect tumor suppressor genes. His own work in plants has often shown epigenetic information can be inherited. The Richards lab specializes i...

Researcher studies, treats military with 'silent disease'

..., blocking the flow of blood through the organ and preventing it from working as it should. Cirrhosis is the twelfth leading cause of death by disease, killing about 26,000 people each year, according to The National Digestive Diseases Information Clearinghouse Web site. Sjogren's clinic provided treatment to...

New research: Soy germ isoflavones reduce bone loss

...oy isoflavones for safely decreasing bone loss and preventing osteoporosis in postmenopausal women." Another recent study published in the journal of Fertility and Sterility demonstrated soy isoflavones' effectiveness and key role in improving mood and cognitive function in postmenopausal women. This research ...

UCLA study finds same genes act differently in males and females

.... "Studies show that aspirin is more effective at preventing heart attack in men than women. One gender may metabolize the drug faster, leaving too little of the medication in the system to produce an effect." "At the genetic level, the only difference between the genders is the sex chromosomes," said Drake....

Report focuses on the role good microbes play in future medicine

...Probiotics could also conceivably be put to use in preventing disease or thwarting autoimmune disorders. A number of these possibilities are being explored in research labs and hospitals around the world," says Richard Walker of the Food and Drug Administration, a co-chair of the steering committee that produc...

Diabetes research takes wing thanks to long-lived fruit fly

... about making people to live to 120 as it is about preventing diseases like diabetes, heart disease, or Alzheimer's. We're trying to identify the mechanisms that cause damage to our body as we age, and prevent them. This has opened a new playing field for people in aging research." The work was initially suppo...

Healing the heart with bone marrow cells

...is is the first step in repairing the heart and in preventing the vicious downward spiral of heart failure in which the heart progressively thins and dilates, eventually causing death." Despite advances in surgical procedures, mechanical assistance devices, drug therapy, and organ transplantation, more than hal...

Trials for new drug to overcome HIV

...osed (see Diagram, left). This cripples the virus, preventing it from infecting any other cells once it buds out from the host. Previous lab experiments on infected human cells have shown that the drug defeats strains of HIV which are resistant to other anti-HIV drugs. A small human trial of the drug, reported...

A surprise about our body clock

Green tea and the 'Asian Paradox'

...viate arthritis. Tea has been used in managing and preventing allergies, diabetes, bacterial and viral infections, cavities, reduce or cure diseases with an inflammatory component and improve neurologic and psychological health. "More studies are necessary to fully elucidate and better understand green tea's m...

Protein's role in regulating cell death sets direction for cancer research

A protein called calpain can be the key either preventing or promoting the cell death, a Queen's University study has found. "This work provides proof in principle that pharmacological inhibition of calpain may be used to block cell death in situations where this is not desirable, such as in neuronal cell...

US infant mortality rate fails to improve

...se of newborn death in the first month of life and preventing premature birth remains at the forefront of the March of Dimes agenda," said Nancy Green, M.D., medical director of the March of Dimes. "We must be more focused upon reversing the stagnancy in the rate of infant mortality, a key indicator of child he...

Knowledge of dendritic cells branches out

...C also have an important educative role to play in preventing autoimmune diseases, such as type 1 diabetes and Multiple Sclerosis, where the body's immune system mistakes "self " for "foreign " and launches an attack. Since DC are central to many immune responses, they are potential targets for the development ...

UGA scientists engineer root-knot nematode resistance

...st-effective and sustainable management tactic for preventing root-knot nematode damage and reducing growers' losses, he said, is to develop resistant plants that prevent the nematode from feeding on the roots. Because root-knot nematode resistance doesn't come naturally in most crops, Hussey's group bioenginee...

New finding points way to foiling anthrax's tricks

...owed that siderocalin tightly binds bacillibactin, preventing it from capturing iron from human cells. However, siderocalin does not prevent petrobactin from binding iron. Interestingly, bacillibactin is very similar to siderophores in other bacteria, including enterobactin, which is produced by several path...

Scientists work to identify genes that contribute to early heart attack risk

... new drug treatments that may be more effective in preventing the development of heart disease," said Herrington. The researchers will take advantage of data from two large-scale studies: LSU Health Sciences Center’s Pathobiological Determinants of Atherosclerosis in Youth (PDAY) study and the Multi-Ethnic St...
