Men who were financially dependent on their wives and who also had more traditional beliefs about gender roles tended to have higher 'allostatic loads,' or wear and tear on the body as the result of stress. Men who had more 'egalitarian' or progressive views about gender seemed to be protected from this effect.
A UC Davis study found that Lactobacillus plantarum bacteria rapidly repaired damaged gut lining (known as leaky gut) in monkeys infected with chronic simian immunodeficiency virus (SIV), an HIV-like virus. It linked chronically inflamed leaky gut to the loss of PPARα signaling and damage to mitochondria.
New insight into how mitochondrial DNA -- separate from the DNA found in a cell's nucleus -- is passed from one generation to the next could have important implications for genetic counseling of women planning pregnancies, especially those carrying disease-causing mutations within their mitochondrial DNA and those suffering from mitochondrial diseases.
Using a relevant animal model (pigs), University of Saskatchewan researchers have shown that mild Zika virus infection in fetuses can cause abnormal brain development in apparently healthy young animals. The study, published Nov. 14, 2019 in PLOS Pathogens, provides new insights into the potential outcomes of Zika virus infection and could point to new prevention and treatment strategies to alleviate the long-term effects of Zika virus infection.
Adolescents and young adults who were born to mothers with HIV but remained uninfected themselves still face a greatly heightened risk of obesity and asthma-like symptoms.
For some women, sex becomes less satisfying with age, with a pronounced decline during perimenopause. A new study indicates that sexual dysfunction increases by nearly 30% during perimenopause, and vaginal dryness most often has the greatest effect on desire, arousal, lubrication, and overall satisfaction. Study results were published this week in Menopause, the journal of The North American Menopause Society (NAMS).
Despite increasing support for the rights of people in the LGBTQ+ community, discrimination remains a critical and ongoing issue for this population, according to researchers. Researchers found that sexual minorities experienced discrimination and victimization at different rates across age.
Vincent Guilamo-Ramos of New York University's Silver School of Social Work unpacks the alarming rate of HIV infections among Hispanics/Latinos, in American Journal of Public Health.
Case Western Reserve University researchers have converted the CRISPR 'recognition induced enzymatic signal' to an electrical signal, which was then used to detect the biomarkers for viruses such as HPV or parvo. They hope the end result could be a new 'universal biosensing' point-of-care medical device -- similar to the existing commercial blood-glucose sensor -- that rapidly and accurately detects those viruses and more.
One in three women of reproductive age have at least one chronic condition that could compromise their health or lead to adverse outcomes during pregnancy, according to University of Utah Health scientists. Yet few of these women are using the most effective forms of contraception to prevent unplanned pregnancies. The researchers say this could be a sign that women with preexisting health problems aren't receiving adequate counseling about birth control.
