DURHAM, N.C. -- Faced with threats such as habitat loss and climate change, thousands of rare flowering plant species worldwide may become extinct before scientists can even discover them, according to a paper published today by a trio of American and British researchers in the journal Proceedings of the Royal Society B.

Imagine being able to drop a toothpick on the head of one particular person standing among 100,000 people in a stadium. It sounds impossible, yet this degree of precision at the cellular level has been demonstrated by researchers affiliated with the Johns Hopkins University Institute for NanoBioTechnology. Their study was published online in June in Nature Nanotechnology.
Many of us are simply overloaded with cholesterol, and now a report in the July issue of Cell Metabolism brings what might be good news: There is more than one way to get rid of that cholesterol, which can otherwise lead to atherosclerosis and heart disease.
There's no substantial quality difference between organically and conventionally produced eggs. That's one of a number of findings in an Agricultural Research Service (ARS) study examining various aspects of egg quality.
ARS food technologist Deana Jones and her team in the Egg Safety and Quality Research Unit in Athens, Ga., found that, on average, there was no substantial quality difference between types of eggs. So, no matter which specialty egg is chosen, it will be nearly the same quality as any other egg.
CINCINNATI – Scientists have used a genetically reprogrammed herpes virus and an anti-vascular drug to shrink spreading distant sarcomas designed to model metastatic disease in mice – still an elusive goal when treating humans with cancer, according to a study in the July 8 Gene Therapy.
Inflammatory bowel disease (IBD) is a disease of the gastrointestinal tract, mainly the intestines that may occur in the people who have genetic potential with a contribution of environmental factors. There has been no definitive medical treatment and drugs usually help the symptoms just to relieve.
The cause of higher incidence of gallstone after radical gastrectomy still remains unknown. Almost all previous studies have attributed gallstone formation to gallbladder motility disorder after gastrectomy, But this theory cannot completely explain it. Is there any other risk factor of gallstone formation after gastrectomy?
Intrahepatic cholangiocarcinoma (ICC) is a cancer of the bile duct in the liver. The clear cell subtype of ICC is a rare cancer; until now, only 8 cases have been reported. The number of reports is so small that a detail description of clear cell ICC is valuable.
Doctors have called for an urgent review of transfusion policies after a UK-wide study of over 200 hospitals found that patients admitted with acute upper gastrointestinal bleeding (AUGIB) are more than twice as likely to suffer further bleeding if they receive a red blood cell transfusion within 12 hours.
The study, in the July issue of Alimentary Pharmacology and Therapeutics, also found that death rates were more than a quarter higher in patients who had received transfusions within that timescale.
High levels of several vitamin E components in the blood are associated with a decreased risk for Alzheimer's disease (AD) in advanced age, suggesting that vitamin E may help prevent cognitive deterioration in elderly people. This is the conclusion reached in a Swedish study published in the July 2010 issue of the Journal of Alzheimer's Disease.
Humanity's rising CO2 emissions could have a significant impact on the world's fish populations according to groundbreaking new research carried out in Australia.
Baby fish may become easy meat for predators as the world's oceans become more acidic due to CO2 fallout from human activity, an international team of researchers has discovered.
Mathematical models for breast cancer detection with microwave tomography are cheaper and less risky
The most popular method of breast cancer detection today is X-ray mammography, which takes images of a compressed breast by low-dose ionizing radiation. However, there are several disadvantages to using X-rays for breast cancer screening, chief among them being the invasivity of radiation and the high costs, which limit their wide use and can deter women from getting them. In addition, depending on the age of the patient and tissue density, X-ray mammograms often result in false positives and negatives.
PITTSBURGH, July 7 – Researchers at the University of Pittsburgh School of Medicine have identified key players in a little-known biochemical pathway that appears to regulate blood pressure. The findings, reported in the early online version of Cardiovascular Research, have evolved from studies conducted by Jeffrey S. Isenberg, M.D., Eileen M. Bauer, Ph.D., and their colleagues at Pitt's Vascular Medicine Institute.
Philadelphia, PA, July 7, 2010 – Approximately 10% of low back pain (LBP) sufferers experience persistent pain and significant disability. In a study published in the August issue of Pain, a group of Australian researchers investigating the relevance of health literacy in patients with chronic lower back pain (CLBP) found that LBP-related beliefs and behaviors affect a person's disability more than pain intensity or a standard measure of functional health literacy.
An expensive treatment recommended for a genetic disorder called alpha-1 antitrypsin deficiency has no proven clinical benefit, according to a systematic review by Cochrane Researchers. The disorder causes chronic lung disease and the review concludes that considering the lack of evidence for its benefits, and possible adverse effects, the treatment should not be recommended.
