Mount Sinai researchers identify potential therapeutic target for improving long-term memory

Mount Sinai researchers have identified insulin-like growth factor II (IGF-II) as a potential therapeutic target for enhancing long-term memory and preventing its loss. IGF-II, a gene expressed during brain development that declines with aging, was found to improve long-term memory in rats by promoting stable LTP.

Data point to role of cellular bioenergetics as a new mechanistic approach to treat immune disorders

Researchers demonstrate the role of cellular bioenergetics in selectively inhibiting pathogenic lymphocytes while preserving normal immune function. Lycera's prototype compound Bz-423 induces selective apoptosis of alloreactive donor T cells, reversing graft-versus-host disease and improving survival in mice.

Megalomaniac CEOs: Good or bad for company performance?

A study published in the Journal of Management Studies found that dominant CEOs can drive companies to extremes of performance. However, a strong board of directors can mitigate this effect and improve company performance. Companies with powerful boards tend to have better outcomes than those without them.

Mercury in Bay Area fish a legacy of California mining

A study using a 'fingerprinting' technique has identified the main sources of mercury in Bay Area fish, tracing it back to sediments and historic mining sites. The findings suggest that small fish acquire mercury from sediments and pass it along to larger fish, highlighting the need for targeted efforts to protect wildlife.

NIH, Gates Foundation and Colorado State team up to find new approach to a TB vaccine

Researchers combined two proteins and a stress response protein to create a new TB vaccine strategy that provided stronger, more long-lasting protection than the current BCG vaccine. The study found that this multistage vaccine controlled reactivation of latent infection and reduced Mtb levels in the lungs more effectively.

Workplace noise-related hearing loss affects sleep quality -- Ben Gurion U. researchers

A study by Ben-Gurion University researchers found that workers with occupational-related hearing loss experienced impaired sleep quality, including insomnia and excessive daytime sleepiness. The study also discovered a significant correlation between tinnitus symptoms and sleep disruptions in workers exposed to harmful noise.

Hemolysis and intestinal injury

A study published in World Journal of Gastroenterology found that hemolysis leads to decreased intestinal microcirculatory blood flow, causing intestinal damage. Elevated circulating cell-free oxyhemoglobin levels resulted in a strong correlation with intestinal injury.
