Researchers have discovered that bone cells' spindly extensions can sense mechanical stimulation, signaling the release of bone-growth factors. This breakthrough could lead to therapies for osteoporosis and bone loss associated with aging.
Researchers at the University of Texas Health Science Center have discovered a family of endogenous capsaicin-like molecules that play an important role in pain biology. They have developed two new classes of analgesics using drugs that either block the synthesis or inactivate these substances.
Researchers found that rapamycin improved learning and memory in Alzheimer's-susceptible mice, correlating with lower brain damage. The study used two different mouse models of early Alzheimer's, both showing similar results.
Researchers found that rapamycin rescued learning and memory deficits in a mouse model of Alzheimer's disease. The study also showed reduced brain lesions similar to those seen in human Alzheimer's patients.
Researchers discovered a link between antioxidant enzyme deficiency and impaired mitochondrial function, leading to muscle cell death. The findings offer new insights into sarcopenia and neuromuscular diseases, potentially paving the way for future muscle-preserving therapies.
A study published in PNAS found that genetics plays a role in the brain's back-burner setup for low-priority ideas. The default-mode network is linked to genetic factors, with over 40% of variance in functional connectivity under genetic control.
Researchers have discovered a novel protein, MRG15, that directs the gene-splicing machinery, leading to aberrant proteins that can damage cells and contribute to diseases such as cancer and aging. This finding has implications for developing new therapies to treat these conditions.
Microbiologists at the University of Texas Health Science Center have discovered a cellular molecule called NOD2 that recognizes two common respiratory viruses and directs cells to mount a defense. The finding holds promise for new therapies against human RSV and influenza A, particularly among vulnerable populations.
Researchers discovered that a compound found in Easter Island soil, called rapamycin, extended the lifespan of middle-aged mice by 28-38% when added to their diet. The findings have significant implications for understanding the aging process and developing new therapies.
A study led by Dr. Antonio Anzueto found that the newer medication moxifloxacin HCI is more effective at treating community-acquired pneumonia (CAP) in elderly patients, with a recovery rate of 97.9%, compared to 90% for the standard medication levofloxacin. The study also assessed cardiac safety and found both treatments to be safe.
In a clinical trial, patients taking oral topiramate were six times more likely to be continuously abstinent for at least one month. The study also showed significant reductions in plasma GGT levels, indicating improved liver health.
