Cell death following blood 'reflow' injury tracked to natural toxin

Researchers at Johns Hopkins have discovered what they believe is the "smoking gun" responsible for most tissue and organ damage after a period of blood oxygen loss followed by a sudden restoration of blood oxygen flow.

   06-12-2007 · EurekAlert!
   Older patients with mild degrees of pre-operative anemia -- low red blood cell count -- or those with a very high red blood cell count have a higher risk of post-operative death or cardiac events following major noncardiac surgery, according to a study in the June 13 issue of JAMA.

2. UF researchers track genetic journey of HIV from birth to death
   10-16-2007 · EurekAlert!
   University of Florida researchers tracked four children born with HIV, studying blood samples taken at birth, throughout life and just after death. Using a high-resolution computational technique, they monitored protein mutations. Previous studies relied on cell culture or animal models to follow the virus' mutations over time. The UF researchers are among the first groups to study the progression of HIV in human patients.

3. UCSD researchers identify critical receptor in liver regeneration
   03-29-2007 · EurekAlert!
   In studies in mouse models, researchers at the University of California, San Diego (UCSD) School of Medicine have found that a cellular receptor involved in triggering cell death is also a necessary component of tissue repair and regeneration immediately following liver injury. This discovery could have implications for early intervention or therapy in liver disease such as cirrhosis or hepatitis.

   Recent studies show promise for significantly reducing vascular aging by inactivating TNFá, which has been linked to blood vessel dysfunction and cell death. The related report by Csiszar et al., "Vasculoprotective effects of anti-TNFá treatment in aging," appears in the January issue of The American Journal of Pathology.

7. Pathway to cell death redefined in landmark study
   09-20-2007 · EurekAlert!
   Researchers from the University of Pittsburgh School of Medicine have determined that an intracellular protein called serpin-6 is crucial to the repair and survival of cell injury. Controlling the process could pave the way to new treatments for cancer, stroke, heart disease, neurological disorders and other killer illnesses. Using a primitive animal model, the scientists also have made cascade of cell death and the role of serpin-6 in saving cells dramatically -- and explosively -- visible.

8. VEGF-B helps nerve cells cheat death without unwanted side effects
   02-07-2008 · EurekAlert!
   The prototypical member of the VEGF family of proteins, VEGF, protects cells in the nervous system from death and degeneration. However, its clinical utility in this regard is limited, because it also induces blood vessel growth, a process known as angiogenesis. However, a new study has revealed that another VEGF family member, VEGF-B, does not have such limitations as it acts as a potent inhibitor of murine retinal cell death while exerting minimal angiogenic effects.

   11-10-2006 · EurekAlert!
   Acute lung injury caused by cell death, high and potentially toxic concentrations of oxygen (hyperoxia), and the resulting excess fluid in the lungs (pulmonary edema), may be controlled by modulating levels of the angiopoietin2 (Ang2) protein, researchers at Yale School of Medicine report in the November 5 online issue of Nature Medicine.

10. Combination therapy reduces tumor resistance to radiation
    06-07-2007 · EurekAlert!
    Radiation is used to treat a variety of tumors as it causes hypoxia and tumor cell death. Recently, radiation-induced hypoxia was shown to trigger tumor resistance to radiation via the activation of new blood vessel formation (angiogenesis). In a new JCI study, researchers show that a combination of radiation treatment and the use of angiogenesis inhibitors such as canstatin is able to overcome HIF-1-dependent tumor survival and increase tumor cell death in mice.
