W.M. Keck Foundation funds study of friendly microbes

.... To do so, the researchers will use a new type of mass spectrometer with an unprecedented capacity to accurately and rapidly identify these metabolites. "We very grateful to the Keck foundation, which has committed itself to funding high-risk projects designed to overcome key obstacles in emerging field...

Current human embryonic stem cell lines contaminated UCSD/Salk team finds

Ecological destruction fuels emerging diseases

...here have been episodes of major climate change or mass extinction, and species have moved out of their areas of origin into other areas, there have been emerging diseases. Parasites have moved into new areas and they've jumped ship into new hosts." He will present his latest findings on February 21 as p...

Inexpensive, mass-produced genes core of synthetic biology advances at UH

Her recent findings onhow to mass produce multiple genes on a single chip are described in apaper titled “Accurate multiplex gene synthesis from programmable DNAmicrochips,?appearing in the current issue of Nature, the weeklyscientific journal for biological and physical sciences res...

Researchers reveal the infectious impact of salmon farms on wild salmon

...ce, the juveniles have had the time to put on body mass and build resistance. The location of the farm near the natal rivers undermines this natural coping strategy. The field study also discovered a new cause for alarm: once the young salmon pass the farm and pick up the sea lice, the migrating school b...

Potential Cure for Lymphoma in HIV patients

...atient had bulky disease (indicated by a cancerous mass greater than 5?10 cm).Reversible abnormalities in liver function, a side effect of theintensive treatment, were experienced in a majority of the patients.One patient, the oldest in the study, developed cardiomyopathy (aweakening of the heart) and kid...

Antibodies from plants protect against anthrax

... place calculated to induce maximum terror through mass casualties. The unpredictable nature of such events compels us to develop cost-effective, highly stable medical countermeasures to enable authorities to treat individuals exposed to bioterror agents such as anthrax," says Les Baillie of the Naval Med...

UF Researchers Map Bacterial Proteins That Cause Tooth Loss

Vascular structure and function improve with diet and exercise

...efficiency of the heart to relax. Left ventricular mass is a measure of end organ damage often following the onset of LVDF abnormalities. The brachial (arm) and carotid (neck) arteries were tested for intima-media thickness and arterial distensibility. Both reflect the health of the blood vessels. The th...

Researchers develop rapid diagnostic tool for pathogen identification

...bes for pathogens were coupled to markers known as mass codes. After amplification, incorporated mass codes were detected by mass spectroscopy allowing identification of the pathogen. According to Thom...

US life expectancy about to decline, researchers say

... everyone who is currently obese acquired the body mass index of people who have the lowest risk of death. By calculating years-of-life-lost due to obesity and combining that with estimates of the prevalence of obesity in younger generations, the authors were able to illustrate that in the coming decades...

How the environment could be damaging men's reproductive health

...s weight; babies born to underweight fathers (body mass index less than 20kg/m2) were six times more likely to have undescended testes. However, Dr Jorgensen said: "This finding should be treated with caution because the number of cases was rather low and only larger studies will be able to show whether ...
