Cancer cells may be able to avoid destruction by anti-vascular and anti-angiogenesis agents

Cancer cells may be able to avoid destruction by anti-vascular and anti-angiogenesis agents through a cellular stress response that activates a pro-survival protein called GRP78, according to researchers from the Keck School of Medicine of the University of Southern California.

HIF-1alpha expression regulates the bactericidal capacity of phagocytes

When microorganisms invade the body, immune mechanisms kick in to fight them off. The infected tissues typically show depleted oxygen levels, and a protein called HIF-1 alpha regulates this. Interestingly, the cells responsible for destroying the foreign pathogens are effective in this low-oxygen environment.

Memory aids help people with schizophrenia remember things just as well as healthy people

When encouraged to use memorization strategies commonly employed by healthy individuals, people with schizophrenia can be helped to remember information just as well as their healthy counterparts, a process that in itself seems to spur a normalization of memory-related activities in the brains of people with schizophrenia, suggests new research from Washington University in St. Louis.

Vasodilators first choice for some heart patients

Few front-line medications exist for treating hospitalized patients with acute decompensated heart failure, a stage of heart failure marked by heightened severity and often-lengthy hospital stays with frequent readmissions. Now, a study suggests the list of preferred drugs for treating the disease might be even shorter.

Showering in manganese-contaminated water could have permanent effects on the nervous system

A new analysis based on animal studies suggests that showering in manganese-contaminated water for a decade or more could have permanent effects on the nervous system. The damage may occur even at levels of manganese considered safe by the Environmental Protection Agency, according to researchers from Wake Forest University School of Medicine.
