Discovery in cell signaling could help fight against melanoma

Discovery in cell signaling could help fight against melanoma

ScienceDaily (May 10, 2012) — The human body does a great job of generating new cells to replace dead ones but it is not perfect. Cells need to communicate with or signal to each other to decide when to generate new cells.

Chronic cocaine use triggers changes in brain’s neuron structure

Chronic cocaine use triggers changes in brain’s neuron structure

ScienceDaily (May 9, 2012) — Chronic exposure to cocaine reduces the expression of a protein known to regulate brain plasticity, according to new, in vivo research on the molecular basis of cocaine addiction. That reduction drives structural changes in the brain, which produce greater sensitivity to the rewarding effects of cocaine.

How cannabis use during adolescence affects brain regions associated with schizophrenia

How cannabis use during adolescence affects brain regions associated with schizophrenia

ScienceDaily (May 8, 2012) — New research from the Royal College of Surgeons in Ireland (RCSI) published in Nature’s Neuropsychopharmacology has shown physical changes to exist in specific brain areas implicated in schizophrenia following the use of cannabis during adolescence. The research has shown how cannabis use during adolescence can interact with a gene, called the COMT gene, to cause physical changes in the brain

Sunscreen ingredient may increase skin cancer risk

ScienceDaily (May 7, 2012) — As vacationers prepare to spend time outdoors this summer, many of them will pack plenty of sunscreen in hopes it will protect their bodies from overexposure, and possibly from skin cancer. But researchers at Missouri University of Science and Technology are discovering that sunscreen may not be so safe after all. Cell toxicity studies by Dr.

NSAIDs and Cardiovascular Risk Explained

ScienceDaily (May 2, 2012) — After nearly 13 years of study and intense debate, a pair of new papers from the Perelman School of Medicine, at the University of Pennsylvania have confirmed exactly how a once-popular class of anti-inflammatory drugs leads to cardiovascular risk for people taking it. It has been almost eight years since Vioxx® was withdrawn by Merck from the market, provoking an intense controversy about the role inhibitors of the enzyme COX-2 play in causing heart attacks and strokes.

Novel regulatory molecules called mirror-microRNAs control multiple aspects of brain function

ScienceDaily (Apr. 27, 2012) — Our genes control many aspects of who we are — from the colour of our hair to our vulnerability to certain diseases — but how are the genes, and consequently the proteins they make themselves controlled?

Why drinking alcohol is linked to breast cancer

Why drinking alcohol is linked to breast cancer

ScienceDaily (Apr. 23, 2012) — A research team presented findings that they say may finally explain the link between alcohol consumption and breast cancer. “Cells have different mechanisms to remove toxic substances, such as ethanol, the chemical name for alcohol, that represent a potential risk to them,” explains María de Lourdes Rodríguez-Fragoso, professor of pharmacology and toxicology at the Universidad Autonoma del Estado de Morelos in Mexico
