Immigrants of the microscopic, bacterial kind live in all human lungs. New research pinpoints just how they get there, and opens the door to more research on what happens to them -- and our bodies -- as a result.
A study published in the Journal of Clinical Lipidology found that higher levels of EPA and DHA omega-3 polyunsaturated fatty acids (PUFA) in red blood cells were associated with a lower risk of all-cause mortality in postmenopausal women. The study analyzed data from more than 6,500 women aged 65-80 who participated in the Women's Health Initiative Memory Study, which began in 1996.
With a new $3 million grant from the National Institutes of Health, Cedars-Sinai Heart Institute investigators are moving closer to their goal of developing a biological pacemaker that can treat patients afflicted with slow heartbeats. The novel, minimally-invasive gene therapy turns patients' normal heart cells into pacemaker cells that regulate heart function - potentially replacing electronic pacemakers one day.
Research published today found testosterone treatment improved bone density and anemia for men over 65 with low testosterone. But the treatment didn't improve patients' cognitive function, and it increased the amount of plaque buildup in participants' coronary arteries.
Adolescents with posttraumatic stress disorder (PTSD) symptoms are more likely to misidentify sad and angry faces as fearful, while teens with symptoms of conduct disorder tend to interpret sad faces as angry, finds a study by NYU's Steinhardt School.
Men who used testosterone replacement therapy to treat symptoms of androgen deficiency had a 33 percent lower risk of cardiovascular events such as heart attacks and stroke compared to those who did not receive any hormone therapy. The findings from the Kaiser Permanente study were published in JAMA Internal Medicine today.
Cancer mortality rates vary considerably within the growing Hispanic population in the United States, with significant differences among the major Hispanic ethnic groups.
Today, in a group of papers published in the Journal of the American Medical Association (JAMA) and JAMA Internal Medicine, researchers found that testosterone treatment improved bone density and anemia for men over 65 with unequivocally low testosterone. However, testosterone treatment did not improve cognitive function, and it increased the amount of plaque buildup in participants' coronary arteries.
The amyloid dye Thioflavin T emerged as the superstar when age researchers in three independent laboratories tested ten already-promising pro-longevity chemicals across a range of distinctive strains and species of tiny nematode worms known as Caenorhabditis. The project, dubbed the Caenorhabditis Intervention Testing Program (CITP), tackled reproducibility, which has been a lingering problem in age research, given that some of the field's most prominent research findings cannot be replicated by other labs.
Older men with low testosterone levels showed improved bone density and strength, as well as reduced anemia, after one year of testosterone therapy, according to a new study conducted at Yale and other sites. The therapy had no impact on cognitive function, however, and may worsen plaque in coronary arteries, said the researchers.
