Published Researchers identify cell signaling pathway controlling melanoma cell metastasis to the brain (via sciencedaily.com) Original source
Researchers have been working to better understand what drives melanoma brain metastasis. They now report on the identification of a cell signaling pathway that regulates the metastatic spread of melanoma cells to the brain.
Published Discrimination during pregnancy can affect infant's brain circuitry (via sciencedaily.com) Original source
Experiences of discrimination and acculturation are known to have a detrimental effect on a person's health. For pregnant women, these painful experiences can also affect the brain circuitry of their children, a new study finds. These effects, the researchers say, are separate from those caused by general stress and depression. The study was published in the journal Neuropsychopharmacology.
Published Spike in premature births caused by COVID, halted by vaccines, study finds (via sciencedaily.com) Original source
COVID-19 caused an alarming surge in premature births, but vaccines were key to returning the early birth rate to pre-pandemic levels, according to a new analysis of California birth records.
Published New clues into the head-scratching mystery of itch (via sciencedaily.com) Original source
Scientists show for the first time that bacteria can cause itch by activating nerve cells in the skin. The findings can inform new therapies to treat itch that occurs in inflammatory skin conditions like eczema and dermatitis.
Published Researchers develop new method for prenatal genetic testing (via sciencedaily.com) Original source
Researchers have developed a non-invasive genetic test that can screen the blood of pregnant individuals to survey all genes from the fetal genome.
Published Discovery of hemoglobin in the epidermis sheds new light on our skin's protective properties (via sciencedaily.com) Original source
Researchers have shown for the first time that hemoglobin, a protein found in red blood cells where it binds oxygen, is also present in the epidermis, our skin's outermost body tissue. The study provides important insights into the properties of our skin's protective external layer.
Published High levels of maternal stress during pregnancy linked to children's behavior problems (via sciencedaily.com) Original source
Children whose mothers are highly stressed, anxious or depressed during pregnancy may be at higher risk for mental health and behavior issues during their childhood and teen years, according to new research.
Published Cancer: Discovery of the mechanisms regulating cancer formation (via sciencedaily.com) Original source
Researchers have discovered the key role of the extracellular environment in dictating the ability of mutated cells to induce cancer formation.
Published Exposure to air pollution in utero may affect reproductive system development (via sciencedaily.com) Original source
From invisible wafts of diesel exhaust to sun-choking plumes of orange smoke, air pollution is known to damage respiratory well-being. Now, research suggests another reason to hold our breath: Polluted air also may hurt reproductive health. In a study of air pollution data in relation to markers of reproductive development in infancy, Rutgers researchers found certain pollutants may negatively alter anogenital distance, a measure of prenatal exposure to hormones.
Published New study finds association between insecticide exposure and lower sperm concentration in adult men (via sciencedaily.com) Original source
Researchers have found in a new systematic review that there is a strong association between insecticide exposure and lower sperm concentration in adult men globally.
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 Clinical trial data suggests prenatal vitamin D reduces a child's risk of asthma (via sciencedaily.com) Original source
A review of 15 years' worth of data found that vitamin D supplementation during pregnancy was linked to reduced rates of asthma and wheezing in children compared to standard prenatal multivitamin.
Published Blood clotting risk quickly drops after stopping hormonal contraceptives (via sciencedaily.com) Original source
Using birth control pills and other hormone-based contraceptives is known to elevate the risk of blood clots, but a new study suggests that this risk largely goes away within two to four weeks after one stops using these contraceptives. The findings can help patients and doctors weigh the benefits and risks of hormonal contraceptives and guide when to stop using them ahead of events that could further increase the risk of dangerous clots, such as major surgery, prolonged periods of immobility, or when tapering anticoagulant medications after a blood clot.
Published Measuring skin water loss predicts anaphylaxis during food allergy tests (via sciencedaily.com) Original source
Measuring skin water loss during food allergy tests may help predict anaphylaxis and keep patients safe. The method aims to detect the life threatening reaction before epinephrine injections are necessary.
Published Infection with common cat-borne parasite associated with frailty in older adults (via sciencedaily.com) Original source
A new study of 601 older adults found that those with higher serointensity -- or a higher concentration of antibiodies -- to the cat-borne parasite Toxoplasma gondii are more likely to show signs of frailty, including exhaustion, loss of muscle mass and other indications of declining health. T. Gondii has previously been associated with risk-taking behavior and mental illness.
Published Paid family leave boosted postpartum wellbeing, breastfeeding rates (via sciencedaily.com) Original source
A new study has found postpartum individuals living in states with generous mandated paid family and medical leave (PFML) are more likely to breastfeed and less likely to experience postpartum depression symptoms compared to those living in states with little or no mandated state-paid leave. The findings were even more pronounced among lower-income populations covered by Medicaid.
Published 'Super melanin' heals skin injuries from sunburn, chemical burns (via sciencedaily.com) Original source
In a new study, scientists show that their synthetic melanin, mimicking the natural melanin in human skin, can be applied topically to injured skin, where it accelerates wound healing. These effects occur both in the skin itself and systemically in the body.
Published Mobile phone use may affect semen quality, study shows (via sciencedaily.com) Original source
Does electromagnetic radiation emitted by mobile phones affect semen quality? While various environmental and lifestyle factors have been proposed to explain the decline in semen quality observed over the last fifty years, the role of mobile phones has yet to be demonstrated. A team has now published a major cross-sectional study on the subject. It shows that frequent use of mobile phones is associated with a lower sperm concentration and total sperm count.
Published Maternal microbiota can affect fetal development (via sciencedaily.com) Original source
Significant differences in the gene activity of the fetal intestine, brain and placenta were identified, depending on the microbes in the mother's body and the compounds produced by them. The findings indicate that maternal microbes are important to her offspring's development and health.
Published Contraceptive pill users less likely to report depression (via sciencedaily.com) Original source
A new study has shown that women who are taking the oral contraceptive pill are less likely to report depression. The research, which analysed data from 6,239 women in the United States aged 18-55 years old, found that the prevalence of major depression amongst users of the oral contraceptive pill (OCP) was significantly lower, at 4.6%, compared to former OCP users (11.4%).
