Second-hand smoke triggers complex inflammatory response

Second-hand smoke is associated with a number of diseases and conditions, including cancer, heart disease, and emphysema. It is an irritant to lung tissue and blood vessels, but the processes through which the body reacts to second-hand smoke comprise a mystery scientists are only beginning to unravel. Researchers at the University of Colorado-Denver are currently studying how second-hand smoke affects the lungs of rats, and so far it appears that second-hand smoke triggers a complex inflammatory response.

Light signaling pathways, circadian rhythms affect biological functions: Research

A new study of the genetic basis of circadian rhythms - the biological responses related to daily light exposure - has found that a few minutes of light exposure in a fungus directly affects a huge range of its biological functions, everything from reproduction to coloring and DNA repair.

Study finds sexual problem common among diabetic patients

Many middle-aged and older adults with diabetes are sexually active according to a study of nearly 2,000 people aged 57 to 85 presented in the September 2010 issue of the journal Diabetes Care. Almost 70 percent of partnered men with diabetes and 62 percent of partnered women with diabetes engaged in sexual activity two or three times a month, comparable to those without diabetes, the study showed.

Hemoglobin variability does not increase mortality in European hemodialysis patients: Study

Fluctuations in blood composition that often arise from commonly used therapies among kidney disease patients are not an independent predictor of adverse outcomes for European hemodialysis patients, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology. The results suggest that although hemoglobin variability is common in kidney disease patients, it does not appear to increase their likelihood of dying early.

Auditory neurons accept first sound, ignore subsequent reverberations: Study

Voices carry, reflect off objects and create echoes. Most people rarely hear the echoes; instead they only process the first sound received. For the hard of hearing, though, being in an acoustically challenging room can be a problem. For them, echoes carry.

Study on impact of harmful de novo gene mutations on autism, schizophrenia

An international study led by University of Montreal scientists suggests family history may not be a good predictor of the presence of mutations predisposing to autism or schizophrenia. The findings show how new or de novo gene mutations alterations of the cell's DNA play a role in these devastating conditions.

Ants use antibiotics to inhibit growth of unwanted fungi, bacteria

Research led by Dr Matt Hutchings and published today in the journal BMC Biology shows that ants use the antibiotics to inhibit the growth of unwanted fungi and bacteria in their fungus cultures which they use to feed their larvae and queen.

U-M researchers explore prevention measures, treatments for C. difficile infection

Clostridium difficile, a wily, familiar bacterium, causes a growing number of serious infections in U.S. hospitals and nursing homes. With a $7.5 million, five-year award from the National Institutes of Health, University of Michigan researchers plan to discover what factors in the microbe and in patients make C. difficile a formidable, costly problem.

Scientist finds man-made chemical enzyme to neutralize toxin

For the first time ever, a completely man-made chemical enzyme has been successfully used to neutralise a toxin found naturally in fruits and vegetables. While studying for her PhD in chemistry at the University of Copenhagen Dr. Jeannette Bjerre showed how a novel so called chemzyme was able to decompose glycoside esculin, a toxin found in horse-chestnuts.

Vitamin A may boost HIV excretion in breast milk: Study

Vitamin A and beta-carotene supplements are unsafe for HIV-positive women who breastfeed because they may boost the excretion of HIV in breast milk thereby increasing the chances of transmitting the infection to the child, a pair of new studies suggest.

Seven year Aspirin for cancer trial

A large clinical trial looking at the cancer preventive actions of aspirin is underway. The seven year study will include six regional centers from Victoria including Ballarat, Bendigo, Geelong, Warrnambool, Traralgon and Shepparton. The ASPirin for Reducing Events in the Elderly (ASPREE) study will involve about 19,000 participants from Australia and the United States.

Pathogens can delay entry into cells to ensure their survival, say researchers

Pathogens make themselves feel at home in the human body, invading cells and living off the plentiful amenities on offer. However, researchers at the Max Planck Institute for Infection Biology, Berlin, together with colleagues at Harvard University, reveal an opposite strategy used to ensure infection success. Pathogens can actually delay their entry into cells to ensure their survival.
