Discovery may lead to better Candidiasis drug

...ing the channel open, causing even better and more rapid killing of the fungus," said Edgerton. "In addition, many other pathogenic fungi that cause disease in elderly individuals or AIDS patients also should be able to be killed by histatins or drugs designed to target their potassium channels."...

Disease diagnosis, biodefense among UH chemical research projects

...her authors, will focus on "Microarray designs for rapid microbial identification." This research is important because infectious diseases cause 26 percent of global mortality and are the third leading cause of death in the United States. Microbial identification also is important in food safety and biod...

Anti cancer virotherapy well tolerated in first human administration, research finds

...ropriate viral material which then reproduces at a rapid rate over a short period of time, devouring the cancer cells in the process by attaching to the cells' ICAM-1 (intercellular adhesion molecule-1) and DAF (decay accelerating factor). This CVA21 technology which has been identified by Professor Shafre...

Fasting intermittently reduces cell proliferation, a marker for cancer risk, study finds

...e found that the effects of the diet regimens were rapid and reversible, with cell division rates and weight going back to normal after refeeding," said Hsieh. "Although it's too early to say whether similar results would be seen in humans, this study at least provides some hope that another option to seve...

Key target for Foot and Mouth drug revealed

...contagious, much easier to get than HIV, and has a rapid onset, which is why outbreaks tend to spread so rapidly," said Dr Curry. "If you wanted to control an FMDV outbreak you could in theory swamp the livestock population with anti-viral drugs for a few weeks and hopefully eradicate the outbreak very qui...

Novel ultrafast laser detection of cancer cells also may improve understanding of stem cells

"For many scientists, [Thompson's] ice cores and the global climate histories contained within them provide the first convincing ...

How important is sexual conflict?

... over its importance. Sexual conflict can generate rapid anatagonistic coevolution between the sexes. This occurs when one sex, usually males, attempt to manipulate reproduction in the other sex, usually females, to the manipulators' benefit. If this manipulation is detrimental to females, females may go o...

Solving sleep problems helps epileptic children

...eased in duration, the children spent less time in rapid eye movement, or REM, sleep, a period in the sleep cycle when brain activity is highest and people dream intensely. The children in the study spent 17 percent of total sleep time in the REM stage. The norm for young adults is 25 percent. "Removing th...

Alcohol 'binges' in rats during early brain development cause circadian rhythm problems

...yndrome, rat pups given alcohol during a period of rapid brain development demonstrated significant changes in circadian or 24-hour rhythms as adults. The alcohol dosage was the equivalent of several nights of binge drinking on the part of a pregnant woman, and it was given at a time during rat brain devel...

On the hunt for deadly frog disease

...tic assays and sampling techniques that enable the rapid detection of the fungus. "We've developed immunohistochemical, molecular and electron microscopy tests for the fungus, along with a range of sampling assays. Using wash water or swabs, tadpoles and frogs can be tested for infection, with the sampling...

Immune cells in the liver take a ride

...tudy showed that the cells were undisturbed by the rapid blood flow, latching on to the vessels, then moving in random patterns in search of infected cells. "Despite the force of the directional blood flow, the cells were able to hold their own, moving and changing direction, sometimes passing each other ...

Ophthalmologists and physicists team up to design 'bionic eye'

...ubretinal placement of implants, the system tracks rapid intermittent eye movements required for natural image perception. Vankov, a physicist, designed the projection and tracking system. "In reality, when you think you are fixating to a certain point, your eyes are not steady," Palanker said. "You are mi...

Zinc supplementation improved mental performance of 7th-grade boys and girls

...nts, says Dr. Penland, because they are undergoing rapid growth and often have poor eating habits. In the study, 209 seventh graders, 111 girls and 98 boys, consumed four ounces of fruit juice containing either 0, 10 or 20 mg of zinc gluconate each school day for 10 to 12 weeks. Students, their parents and...

Ebola virus: from wildlife to dogs

...accine is currently available, only prevention and rapid control of epidemics by isolation of disease victims can limit its spreading. Since 2001, IRD research scientists and their partners (1) have been working to unravel the virus's biological cycle, in other words the whole range of ways in which the vi...
