Allergy to hair dye increasing

...mer market, but no satisfactory or widely accepted alternatives to these agents are available for use in permanent hair dye. Dermatologists report anecdotally that the frequency of positive reactions to PPD on patch testing is increasing. This was confirmed in a recent survey in London, which found a doubling ...

Shedding new light on proteorhodopsin

...tentially significant boost for efforts to develop alternatives to fossil fuel energy sources. Microbes that can simultaneously harvest energy from several different sources may be better at producing biofuels than microbes that can only utilize a single energy source. The results of this study appear in a pa...

Mailman School of Public Health researchers report blood DNA can be early predictor of liver cancer

...ties illustrates the lack of effective therapeutic alternatives for this disease. The Mailman School researchers and colleagues studied the blood of patients enrolled in a cancer screening program in Taiwan, who provided repeated blood samples prior to diagnosis. A total of 12,000 males and over 11,900 fema...

...billion gallons by 2012. Among the most promising alternatives are fuels derived from biological material. Currently, the main biofuel used in the United States is ethanol distilled from kernels of corn. There are about 140 corn ethanol refineries nationwide, which produce more than 5 billion gallons a year. But...

Cryoablation -- A new treatment option for some kidney tumor patients

...s urologists and radiologists collaborated to find alternatives for these individuals. If these patients are frail due to age or illness or are not able to have surgery because of other factors, percutaneous cryoablation may be an option. "This procedure appears to be a good option for some patients," says Th...

Uncovering DNA's 'sweet' secret

Edible coatings will be the packaging of the future

... completely biodegradable. One of the most popular alternatives in the last few years is the edible coating ?a transparent film that covers the food item and acts as a barrier to humidity and oxygen. Moreover, these films can be used as a host for additives in the conservation of the properties of the product or ...

Small, smaller, smallest -- The plight of the vaquita

...rticularly in ones that offer viable socioeconomic alternatives to fishermen. Mexico has a very good record in helping endangered marine mammals to recover. There are no better examples anywhere in the world than eastern Pacific gray whales and northern elephant seals, both of which came back from low numbers ...

Humpback whales have brain cells also found in humans

...d primate brains may be considered as evolutionary alternatives in neurobiological complexity and as such, it would be compelling to investigate how many convergent cognitive and behavioral features result from largely dissimilar neocortical organization between the two orders." They also suggest that the current...

New research: Soy germ isoflavones reduce bone loss

... is imperative to find natural, safe and effective alternatives for women to help maintain bone health after menopause ?without the risky side effects associated with long-term hormone replacement therapy use. This promising research is another step in advancing soy germ isoflavones as a safe, effective option,"...

New bird flu drug promises to beat the problem of resistance

... flu pandemic, but we need to be working on better alternatives that do not suffer the same inherent resistance problems," said Dr Andrew Watts from the Department of Pharmacy and Pharmacology at the University of Bath. "We are still in the very early stages of the development of this class of molecules into a ...

UC Davis researchers move biotechnology closer to replacing electronic pacemakers

... have been working for years to develop biological alternatives to drugs and electronic devices for treating heart arrhythmias ?heartbeats that are irregular in rhythm, rate or sequence. The sinoatrial (SA) node, a patch of cells called the pacemaker, generates cardiac rhythms for coordinated contractions and blo...

New understanding of COX-1 and COX-2 enzymes could revise classification of pain meds

...in medications. It is now pointing toward possible alternatives to drugs like Vioxx and Celebrex, says Dr. Funk. A study published April 13 by The Journal of Clinical Investigation (JCI) by the same research team found that new types of anti-inflammatory drugs may reduce COX-2 cardiovascular problems. That stud...

Today, Sevante is virtually pain free. "After my first amputation, I would have done anything to avoid a second," said Sevante....

Stem cells can repair torn tendons or ligaments

Alternatives to the use of nitrate as a fertiliser

... is required is a study of nitrogenated sources as alternatives to the nitrates that predominate in agricultural soils and that have a greater contaminant capacity. The current use of nitrates as a nitrogenated fertiliser in intensive farming has given rise to environmental problems such as the contamination of w...

Cheaper and simpler keyhole surgery
