Study shows pine bark naturally decreases severe chronic venous insufficiency

...ed Thrombosis/Hematosis show a significant symptom reduction of chronic venous insufficiency (CVI) in patients after supplementing with Pycnogenol® (pic-noj-en-all), an antioxidant plant extract from the bark of the French maritime pine tree. Over 35 years of research on Pycnogenol® demonstrate the antioxidan...

Neural stem cell gene plays crucial role in eye development

...severity of this condition. "We found that even a reduction in normal SOX2 levels causes problems in these mice and this mimics the problems seen in humans," said Pevny. The scientist pointed out that the problem in eye development in these mice results from loss of SOX2 mediated maintenance of the neural p...

Bird brains shrink from exposure to contaminants

...les, some of which experienced up to a 30 per cent reduction in brain region size compared to males at lower DDT exposure levels. Whether this also applies to other animals and humans is unclear because there is not yet a strong understanding of how these chemicals in the environment affect the brain, but i...

Natural pine bark extract relieves muscle cramp and pain in athletes and diabetics

...o had experienced normal cramping had a 25 percent reduction in the number of cramps experienced while taking P...with venous insufficiency experienced a 40 percent reduction in the number of cramps, and athletes with frequent cramping experienced a 13 percent reduction in t...

Quitting smoking improves lung function considerably

...bronchoconstrictor effects of cigarette smoke or a reduction in the proinflammatory effects of cigarette smoke ...nction test scores, the "quit" group also showed a reduction in sputum neutrophil counts when compared to those of smokers. Neutrophils are white blood cells (ph...

New stem-cell findings can help the body to cure itself

...s are produced. As many serious disorders cause a reduction in the production of new cells, scientists are keen to develop drugs that stimulate the process, which in turn could help the body to cure itself. It has long been known that the new cells are often formed by immature cells known as stem cells, but ...

Scientists to employ Arctic ice and polar bears to protect diversity of world's crops

...humans. The ferrets experienced a more significant reduction of virus multiplication than otherwise would have occurred, the researchers reported. Moreover, the infections failed to spread out of the upper respiratory tract to the lungs or brain. "These findings are especially significant because ferrets are...

Moreover, the infections failed to spread out of the upper respiratory tract to the lungs or brain. "These findings are especially significant because ferrets are...

Fatty spheres loaded with siRNA shrink ovarian cancer tumors in preclinical trial

...ncing liposome with docetaxel boosted tumor weight reduction to the 94-98 percent range. These results also held up in experiments with ovarian cancer cell lines resistant to docetaxel and to the chemotherapy drug cisplatin. The FAK-silencing liposome and the liposome with chemotherapy also reduced the...

New egg freezing technique offers hope to hundreds of women

... the other possible alterations are concerned, the reduction in amount and density of the cortical granules and the consequent hardening of the zona pellucida in frozen-thawed oocytes may be an expected phenomenon that possibly could be by-passed by the application of ICSI technique at insemination; other zona...

Novel therapy combinations gain ground in treating hepatitis

...2 weeks, a primary response to therapy, noted as a reduction in hepatitis RNA, was observed in 83 percent of patients in the CIFN group and 78 percent of the pegIFN group. At the end of treatment at week 72, the vast majority (89 percent) of both the CIFN group and pegIFN group (76 percent) were in remission. ...

Heart has enough oxygen to survive hypothermia, CPR crucial

...5°C, both hypothermic groups experienced a similar reduction in circulating blood volume. And both showed that the physiological mechanisms that help transport oxygen and help unload oxygen from hemoglobin were working. "As a consequence, oxygen supply was not a limiting factor for survival in the present expe...

Elephants, large mammals recover from poaching in Africa's oldest national park

... of ICCN and its partners are finally leading to a reduction in the level of poaching." Established in 1925, Virunga National Park remains the most species rich park in Africa. It once boasted the highest density of large mammals in the world before a wave of unrest and poaching descended upon the region. Sin...

New study reveals components of cocoa may enhance the appearance of the skin

... against UV light. Study participants exhibited a reduction in the redness of skin following exposure to artificial sunlight. The authors of the study believe the skin benefits of cocoa flavanols may be due in part to an improvement in blood flow to the skin. Consistent with previous studies that demonstrate...

Virtual realities against pain

...t's limited capacity for attention, resulting in a reduction in the patient's attention to the stimulus and therefore a reduction in the stimulus itself. It was assumed that the ideal distractor would require an optimum amount of ...

Device effective in zapping the pain out of migraines

... the patients in this study reported a significant reduction in nausea, noise and light sensitivity post treatment. "Perhaps the most significant effect of using the TMS device was on the two-hour symptom assessment, with 84 percent of the episodes in patients using the TMS occurring without noise sensitivit...

RNA interference stops colon cancer spread in mice

...I3K proteins into the mice. The result was a major reduction in the spread of colorectal cancer to the liver. Evers and the paper's other authors -- UTMB research fellows Piotr Rychahou and Lindsey Jackson and pathology professor Srinivasan Rajaraman -- also conducted a detailed analysis of the PI3K pathway...

Production of key Alzheimer's protein monitored for first time in humans

...rease in the mechanisms that make the protein or a reduction in the processes that regularly clear it from the brain. Because Alzheimer's symptoms take many years to develop, some researchers had assumed that the creation and clearance rates for Abeta were very slow. But the initial test of the new technique...

Chemical in many air fresheners may reduce lung function

...modest reductions in lung function. "Even a small reduction in lung function may indicate some harm to the lungs," said NIEHS researcher Stephanie London, M.D., lead investigator on the study. "The best way to protect yourself, especially children who may have asthma or other respiratory illnesses, is to redu...

Iron critical to ocean productivity, carbon uptake

...bon uptake is estimated at 50 billion tons, so the reduction in the estimate of the uptake is significant ?about 2 to 4 percent. Results of the study were published this week in the journal Nature. When stressed by a lack of iron, phytoplankton create additional pigments that fluoresce, or light up, unlike n...
