Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer
The genome sequence of the parasitic amoeba Entamoeba histolytica, a leading cause of severe diarrheal disease in developing countries, includes an unexpectedly complex repertoire of sensory genes as well as a variety of bacterial-like genes that contribute to the organism's unique biology. The report, which appears in the February 24 issue of Nature, presents the first genome-wide study...Light therapy may combat fungal infections, new evidence suggests
A newly discovered mechanism by which an infectious fungus perceives light also plays an important role in its virulence, according to Howard Hughes Medical Institute investigators at Duke University Medical Center. The findings suggest that changes in light following fungal invasion of the human body may be an important and previously overlooked cue that sparks infection, the researchers said.</...Evidence of 600-million-year old fungi-algae symbiosis discovered in marine fossils
Researchers from China and the United States have found evidence of lichen-like symbiosis in 600-million-year-old fossils from South China. The previous earliest evidence of lichen was 400 million years old, discovered in Scotland. The discovery also adds to the scarce fossil record of fungi and raises new questions about lichen evolution. Xunlai Yuan, a paleontologist with the Nanjing Ins...Researchers find first evidence of venom system in extinct mammal
A tiny fossil found more than 10 years ago in central Alberta has proved to be the key to answering a long unsolved evolutionary question, say researchers from the University of Alberta. Back in 1991, Dr. Richard Fox and his research team found a 60 million year-old incomplete skull fossil that they now believe is the first evidence of an extinct mammal with a venom delivery apparatus. Th...Scientists find evidence of catastrophic sand avalanches, sea level changes in Gulf of Mexico
Identical twins lose some fundamental similarities as they grow older, a new study reports. Researchers report in this week's Proceedings of the National Academy of Sciences that these differences may stem from changes in the epigeno...What patients want: A story of choice, clinical trials & evidence-based medicine
What is less obvious is that c...Evidence Links Protein Damage to Neurodegenerative diseases like Parkinson's and Alzheimer's
Neurodegenerative diseases - including Parkinson's, Alzheimer's, Diffuse Lewy body disease, and Multiple System Arophy - are collectively called synucleinopathies. Most commonly they become symptomatic due to a deficiency of a specific neurotransmitter - in the case of Parkinson's it is dopamine. When the neurons that produce these chemicals die or become impaired, which occurs with oxidation, th...Evidence supporting H.pylori eradication
A study of patients on long-term non-steroidal anti-inflammatory drug (NSAID) treatment has shown that eradication of Helicobacter pylori infection can substantially reduce the risk of ulcer formation.// Treatment with omeprazole triple therapy eradicated 90 per cent of H.pylori infections and reduced the six-month ulcer probability of 34 per cent found in the control group to 12 per cent in the...Evidence against use of Beta blockers as first choice in the treatment of primary hypertension
Beta blockers have been used widely in the treatment of hypertension and are still recommended as first-line drugs in hypertension guidelines. Moreover, after myocardial infarction and in patients with heart failure, treatment // with beta blockers prevents re-infarction, hospitalisation for heart failure, and premature death. However, a preliminary analysis has shown that atenolol is not very ef...Evidences that Better Health Care Facility is Offered By Public Hospitals.
In Canada questions have arisen about the best approach whether it is public or private for healthcare. The evidences point out to be that more people want public services offering better health care facilities. // In Britain the London’s public Queen Elizabeth Hospital is an example financial difficulty due to public-private partnership (P3s). In the US a study reveals that...Drugs of Abuse Array Evidence Opiates Assay

ROCHESTER, Minn., April 30. 2007-- Scientific evidenceincreasingly links arterial calcification to the presence ofnanosized particles -- so small that some scientists questionwhether a nanoparticle can live and, if so, play a viable role incausing disease. A new Mayo Clinic study cites evidence showing the presence ofnanoparticles near plaque-filled arteries in animal models....
