Published Researchers are using RNA in a new approach to fight HIV (via sciencedaily.com) Original source
A pharmacy associate professor has developed a novel nanomedicine loaded with genetic material called small interfering RNAs (siRNA) to fight human immunodeficiency virus (HIV) using gene therapy.
Published Double risk of dementia after mouth ulcer virus (via sciencedaily.com) Original source
People who have had the herpes virus at some point in their lives are twice as likely to develop dementia compared to those who have never been infected. A new study confirms previous research on whether herpes can be a possible risk factor for dementia.
Published Turning back the clock on photoaging skin (via sciencedaily.com) Original source
A new study examines dermal injections and their impact on skin aging.
Published A more eco-friendly facial sheet mask that moisturizes, even though it's packaged dry (via sciencedaily.com) Original source
Starting a new year, many people pledge to enact self-care routines that improve their appearance. And facial sheet masks soaked in skin care ingredients provide an easy way to do this. However, these wet masks and their waterproof packaging often contain plastics and preservatives. Now, a study reports a dry-packaged hydrating facial mask that is made of biobased and sustainable materials.
Published Genetic variants underlying male bisexual behavior, risk-taking linked to more children, study shows (via sciencedaily.com) Original source
Because same-sex sexual behavior does not result in offspring, evolutionary biologists have long wondered how the genes associated with this behavior have persisted in the human genome, and whether they will remain in the future. A new study suggests that part of the explanation -- specifically for male bisexuals -- has to do with risk-taking behavior.
Published Scientists 3D-print hair follicles in lab-grown skin (via sciencedaily.com) Original source
Scientists have 3D-printed hair follicles in human skin tissue cultured in the lab. This marks the first time researchers have used the technology to generate hair follicles, which play an important role in skin healing and function. When it comes to engineering human skin, hair may at first seem superfluous. However, hair follicles are quite important: They produce sweat, helping regulate body temperature, and they contain stem cells that help skin heal. The finding has potential applications in regenerative medicine and drug testing, though engineering skin grafts that grow hair are still several years away.
Published Morning-after pill more effective when taken with an anti-inflammatory painkiller, researchers find (via sciencedaily.com) Original source
A research team recently published findings on adding an anti-inflammatory painkiller used for arthritis pain to an oral emergency contraceptive pill (also known as the morning-after pill) to increase the effectiveness of pregnancy prevention.
Published Syphilis transmission networks and antimicrobial resistance in England uncovered using genomics (via sciencedaily.com) Original source
Scientists use genomics to uncover syphilis transmission patterns in England, in a pioneering new approach for STI surveillance.
Published New study shows effectiveness of mpox vaccine (via sciencedaily.com) Original source
A new international study has shown mpox (formerly known as monkeypox) infections to be less severe among those who are vaccinated or had a previous infection in 2022, underlining the importance and effectiveness of vaccination.
Published Why men, wealthy people and maritime residents are more likely to develop skin cancer (via sciencedaily.com) Original source
A new study examines why people living in Atlantic regions are more at-risk for developing melanoma than other Canadians, providing lessons on skin cancer prevention for the whole country. To find out why, the researchers compared UV exposure and behaviours among different groups in Atlantic Canada based on income, education, and gender, among other factors.
Published Why does skin get 'leathery' after too much sun? Bioengineers examine cellular breakdown (via sciencedaily.com) Original source
A study explores how ultraviolet radiation can alter the microstructure of human skin. Particularly affected is collagen, the fibrous protein that binds together tissue, tendon, cartilage and bone throughout our bodies.
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 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.
