Cicardian system suffers and protects from prenatal cocaine exposure

07-10-2007 · EurekAlert!

Researchers from Boston University School of Medicine have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin signaling, growth and neurotransmission. The circadian factors, including the principal circadian hormone melatonin, can attenuate the prenatal effects of cocaine. These findings appear in the July 11 issue of the journal PLoS ONE.

Antibodies protect mice from developing respiratory tularemia
06-27-2007 · EurekAlert!
A research team led by Dennis W. Metzger, Ph.D., at the Albany Medical College in New York has now shown that treating laboratory mice with a serum containing tularemia-specific antibodies protects the mice against F. tularensis, not only if given before exposure to lethal doses of inhalational F. tularensis but also up to 48 hours after exposure. These findings suggest a possible alternative treatment approach to traditional antibiotics.

Choline shows promise in reducing behavioral effects associated with prenatal alcohol exposure
02-28-2007 · EurekAlert!
Giving choline to infants who were exposed in the womb to alcohol may mitigate some of the resulting problems. Prenatal alcohol exposure affects physical and central nervous system development, putting children at risk for fetal alcohol spectrum disorders that at their worst include full-blown fetal alcohol syndrome. These disorders can mean a lifetime of potentially serious problems with learning, attention, motor skills and social behavior.

Intravenous gene therapy protects normal tissue of mice during whole-body radiation
10-28-2007 · EurekAlert!
Gene therapy administered intravenously could be used as an agent to protect vital organs and tissues from the effects of ionizing radiation in the event of large-scale exposure from a radiological or nuclear bomb. In the University of Pittsburgh study, mice were used to test the protective effects of manganese superoxide dismutase plasmid liposome gene therapy on the bone marrow during whole-body irradiation.

Gene therapy administered intravenously could be used as an agent to protect vital organs and tissues from the effects of ionizing radiation in the event of large-scale exposure from a radiological or nuclear bomb. In the University of Pittsburgh study, mice were used to test the protective effects of manganese superoxide dismutase plasmid liposome (MnSOD-PL) gene therapy on the bone marrow during whole-body irradiation.

UVA researchers explain cell response to skin-damaging UV rays
10-01-2007 · EurekAlert!
Researchers at the University of Virginia Health System have published a new study that helps scientists around the world expand the body of knowledge on how cells protect themselves (or not) from DNA damage caused by UV rays. Their study reveals part of a 'simple switch' mechanism inside cells, triggered by UV exposure from the sun, that helps our cells survive and thrive after being exposed. This mechanism involves an unanticipated connection between several proteins in the cell, the researchers discovered.

Violent sex acts boost insect's immunity system
12-04-2007 · EurekAlert!
The long-held idea that only vertebrates have sophisticated adaptive immune systems that can protect them for life against many pathogens after being infected by them just once has been revised in recent years. It turns out that many insects also have a form of immune memory that protects them against reinvasion by a pathogen they have previously encountered.

New York Subway Noise Levels Can Result In Hearing Loss For Daily Riders
10-15-2006 · ScienceDaily
In a new survey of noise levels of the New York City transit system, researchers at Columbia University's Mailman School of Public Health found that exposure to noise levels in subways have the potential to exceed recommended guidelines of the World Health Organization (WHO) and the US Environmental Protection Agency (EPA). According to the research, as little as 30 minutes of exposure to decibel levels measured in the New York City transit system per day has the potential to result in hearing loss.

Prenatal alcohol exposure appears to increase an infant's stress response
11-27-2006 · EurekAlert!
little is known about the effects of prenatal alcohol exposure (PAE) on stress systems in infants. New findings indicate that the greater the PAE, the greater the cortisol, autonomic and emotional responses to social challenges in young infants. The days between conception and pregnancy recognition may be especially critical for fetal stress-response development.
