Published New study links contraceptive pills and depression (via sciencedaily.com) Original source
Women who used combined contraceptive pills were at greater risk of developing depression than women who did not, according to a new study. Contraceptive pills increased women's risk by 73 per cent during the first two years of use.
Published Low sexual satisfaction linked to memory decline later in life (via sciencedaily.com) Original source
Low sexual satisfaction in middle age may serve as an early warning sign for future cognitive decline, according to a new study. The study, which tracked associations between erectile function, sexual satisfaction and cognition in hundreds of men aged 56 through 68, found that declines in sexual satisfaction and erectile function were correlated with future memory loss.
Published Tuberculosis disease intensifies HIV antibody response in people with HIV (via sciencedaily.com) Original source
New research found that people living with HIV that have had pulmonary tuberculosis had broader and more potent HIV antibody responses and differences in HIV sequences predicted to be antibody resistant as compared to those without suspected or documented tuberculosis.
Published New genetic target for male contraception identified (via sciencedaily.com) Original source
Discovery of a gene in multiple mammalian species could pave the way for a highly effective, reversible and non-hormonal male contraceptive for humans and animals. Researchers identified expression of the gene, Arrdc5, in the testicular tissue of mice, pigs, cattle and humans. When they knocked out the gene in mice, it created infertility only in the males, impacting their sperm count, movement and shape.
Published Smells influence metabolism and aging in mice (via sciencedaily.com) Original source
Exposure to female odors and pheromones causes weight loss and extend the life spans of mice, which may have implications for humans, researchers have found. While it was already known that sensory cues in humans and animals influence the release of sex hormones, this study shows that these cues could have more wide-spread physiological effects on metabolism and aging.
Published Boosting the body's anti-viral immune response may eliminate aging cells (via sciencedaily.com) Original source
Aging cells express a protein that is produced by human cytomegalovirus and is targeted by certain immune cells in the body. Harnessing the immune response to this protein could have multiple health benefits during aging.
Published Scientists see anti-aging potential in an invasive weed (via sciencedaily.com) Original source
The fruit of the cocklebur plant, which grows worldwide and is often considered a noxious weed, has antioxidant and anti-inflammatory components that could make it useful as a skin protectant, according to new research.
Published A readily available dietary supplement may reverse organ damage caused by HIV and antiretroviral therapy (via sciencedaily.com) Original source
MitoQ, a mitochondrial antioxidant that is available to the public as a diet supplement, was found in a mouse study to reverse the detrimental effects that HIV and antiretroviral therapy (ART) have on mitochondria in the brain, heart, aorta, lungs, kidney and liver.
Published 3D-printed scaffold could improve breast reconstruction results (via sciencedaily.com) Original source
Investigators have developed a technique to help surgeons reconstruct more natural-looking nipples for patients who have undergone breast reconstruction after mastectomy to treat breast cancer.
Published High infant mortality rates and global human population rise (via sciencedaily.com) Original source
New research showing high infant mortality rates are contributing to an incessant rise of the global human population supports arguments for greater access to contraception and family planning in low- and middle-income nations.
Published Simple laser treatments may help prevent nonmelanoma skin cancer (via sciencedaily.com) Original source
In a study of patients with a history of facial keratinocyte carcinoma, 20.9% of those treated with nonablative fractional lasers experienced a subsequent keratinocyte carcinoma, compared with 40.4% of patients who did not receive laser treatment.
Published Call to address women's reproductive needs holistically (via sciencedaily.com) Original source
Women's reproductive needs should be considered holistically by considering pregnancy prevention and pregnancy preparation at the same time, finds a new study.
Published Scars mended using transplanted hair follicles (via sciencedaily.com)
Researchers have found that hair follicle transplants can promote scar rejuvenation by altering their architecture and genetic makeup.
Published COVID vaccines also help protect HIV patients, study finds (via sciencedaily.com)
Researchers have found that people infected with HIV who receive antiretroviral therapy form antibodies against Sars-Cov-2 after being vaccinated against COVID with mRNA vaccines. Their immune response to the vaccination is, however, less strong than that of healthy people. A third vaccination reduces this gap.
Published Previously unknown ability of the autonomic nervous system discovered (via sciencedaily.com) Original source
The autonomic nervous system is known as the control center for involuntary bodily processes such as the beating of our hearts and our breathing. The fact that this part of the nervous system also has the ability to spontaneously restore muscle function following a nerve injury was recently discovered. Their findings may form the basis for improving and developing interventions to treat nerve lesions.
Published Converging and diverging immune factors that may predispose people to HIV and HSV (via sciencedaily.com) Original source
Investigators analyzed longitudinal samples of cervical and serum biomarker levels for immune activation, before and after subjects acquired HSV-2. They found that altered levels of specific biomarkers in the mucosa and serum were associated with HSV-2 acquisition only, while others overlapped with biomarkers and combinations predictive of HIV-1 acquisition.
Published Three-dose hepatitis B vaccine regimen protects people with HIV (via sciencedaily.com) Original source
A three-dose course of the hepatitis B vaccine HEPLISAV-B fully protected adults living with HIV who had never been vaccinated against or infected with the hepatitis B virus (HBV), according to new study.
Published Sexual assault-related ER visits increase more than tenfold (via sciencedaily.com) Original source
An increasing number of people are seeking emergency medical help for sexual assault, according to a new study.
Published A cut above -- two devices are teamed to simplify, quicken and improve ear reconstruction (via sciencedaily.com)
Thanks to two novel tools, the traditionally difficult surgery to create a replacement ear from a patient's rib cartilage may soon be done faster, more simply and accurately.
Published Mucus-based lubricant proves highly effective against HIV and herpes, study finds (via sciencedaily.com)
Cow mucus provides the basis for a synthetic prophylactic gel developed to protect against HIV and herpes transmission. The lubricating gel proved 70 percent effective in lab tests against HIV, and 80 percent effective against herpes.
