Zinc Levels In Seminal Plasma Are Associated With Sperm Quality In Fertile And Infertile Men
UroToday.com - Insufficient intake of zinc (Zn) can impair antioxidant defenses and may be an important risk factor in oxidant release, compromising the mechanism of DNA repair, and making the sperm cell highly susceptible to oxidative damage. In the absence of Zn, the possibility of increased oxidative damage exists that would contribute to poor sperm quality. Infertile men and men who smoke are very susceptible to oxidative damage induced by free radicals. In the present study, we hypothesized that major changes in the level of seminal Zn levels are related with low quality of sperm and poor fertilizing capacity.

Senators Seek $100 Billion For Health Reform From Insurers
"Key senators say they want to force the health insurance industry to pay as much as $100 billion toward the 10-year cost of the health care overhaul sought by President Obama," CQ Politics reports. The fees would come on top of a variety of other potential provisions that will change the landscape of their industry, from the requirement that insurers cover people with pre-existing conditions to a government-run plan meant to compete with insurers. The fee may appear in a Finance Committee version of the reform plan that hasn"t been released yet. That committee is responsible for finding ways to pay for the overhaul.

Brain Plasticity: Changes And Resets In Homeostasis

In an article published in the June 25th edition of the journal Neuron, researchers at the Hotchkiss Brain Institute, University of Calgary, have found that synaptic plasticity, long implicated as a device for "change" in the brain, may also be essential for stability. Homeostasis, the body"s own mechanism of regulating and maintaining internal balance in the body, is necessary for survival. Precisely how the brain pulls off this tricky balancing act has not been well appreciated. By examining neural circuits that regulate fluid volume, Jaideep Bains, PhD, and colleagues, Brent Kuzmiski, PhD, and Quentin Pittman, PhD, have demonstrated that multiple forms of synaptic plasticity work to ensure that an effective response to a life-threatening challenge is followed by an immediate recovery of these neural circuits to pre-challenge conditions. These observations provide the first set of synaptic rules that help us understand how homeostatic setpoints are re-set in vivo. Based on their findings, Bains and colleagues, demonstrate that synaptic plasticity is essential for maintaining stability in a nervous system constantly bombarded by inputs from the outside world. This research was supported by the Canadian Institutes of Health Research (CIHR) and the Heart and Stroke Foundation of Alberta, Yukon and NWT. Bains is an AHFMR (Alberta Heritage Foundation for Medical Research) senior scholar while Pittman is an AHFMR medical scientist. Bains is an associate professor and Pittman a professor in the Department of Physiology and Biophysics. Both are members of the Hotchkiss Brain Institute in the Faculty of Medicine at the University of Calgary. Lisa Fleece University of Calgary
