Resetting the circadian clock: Shift workers might want to skip high-iron foods at night

Resetting the circadian clock: Shift workers might want to skip high-iron foods at night

Workers punching in for the graveyard shift may be better off not eating high-iron foods at night so they don’t disrupt the circadian clock in their livers. Continue reading

Presence of enzyme may worsen effects of spinal cord injury and impair long-term recovery

Presence of enzyme may worsen effects of spinal cord injury and impair long-term recovery

Traumatic spinal cord injury (SCI) is a devastating condition with few treatment options. Studies show that damage to the barrier separating blood from the spinal cord can contribute to the neurologic deficits that arise secondary to the initial trauma. Through a series of sophisticated experiments, researchers reporting in The American Journal of Pathology suggest that matrix metalloproteinase-3 (MMP-3) plays a pivotal role in disruption of the brain/spinal cord barrier (BSCB), cell death, and functional deficits after SCI.

Sugared soda consumption, cell aging associated in new study

Sugared soda consumption, cell aging associated in new study

Sugar-sweetened soda consumption might promote disease independently from its role in obesity, according to UC San Francisco researchers who found in a new study that drinking sugary drinks was associated with cell aging. The study revealed that telomeres — the protective units of DNA that cap the ends of chromosomes in cells — were shorter in the white blood cells of survey participants who reported drinking more soda.

Discovery of cellular snooze button advances cancer, biofuel research

The discovery of a cellular snooze button has allowed a team of Michigan State University scientists to potentially improve biofuel production and offer insight on the early stages of cancer. Continue reading

Universal Ebola drug target identified by researchers

Universal Ebola drug target identified by researchers

University of Utah biochemists have reported a new drug discovery tool against the Ebola virus. According to a study published in this week’s online edition of Protein Science , they have produced a molecule, known as a peptide mimic, that displays a functionally critical region of the virus that is universally conserved in all known species of Ebola. This new tool can be used as a drug target in the discovery of anti-Ebola agents that are effective against all known strains and likely future strains Continue reading

Survival molecule helps cancer cells hide from the immune system

Survival molecule helps cancer cells hide from the immune system

A molecule that helps cancer cells evade programmed self-destruction, an internal source of death, might also help malignant cells hide from the immune system, an external source of death. A new study by researchers at The Ohio State University Comprehensive Cancer Center — Arthur G. James Cancer Hospital and Richard J Continue reading

The immune system functions as the body’s police force, protecting it from intruders like bacteria and viruses. However, in order to ascertain what is happening in the cell it requires information on the foreign invaders. This task is assumed by so-called immunoproteasomes Continue reading

Search for better biofuels microbes leads to human gut

Search for better biofuels microbes leads to human gut

Scientists have scoured cow rumens and termite guts for microbes that can efficiently break down plant cell walls for the production of next-generation biofuels, but some of the best microbial candidates actually may reside in the human lower intestine, researchers report. Continue reading
