Published Human embryo-like models created from stem cells to understand earliest stages of human development (via sciencedaily.com) Original source
Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why and how pregnancies fail.
Published Helping 'good' gut bacteria and clearing out the 'bad' -- all in one treatment (via sciencedaily.com) Original source
Probiotics can help maintain a healthy gut microbiome or restore populations of 'good bacteria' after a heavy course of antibiotics. But now, they could also be used as an effective treatment strategy for certain intestinal diseases, such as Crohn's disease. Researchers have developed a microgel delivery system for probiotics that keeps 'good' bacteria safe while actively clearing out 'bad' ones. In mice, the system treated intestinal inflammation without side effects.
Published One in five women become pregnant naturally after having a baby conceived with IVF (via sciencedaily.com) Original source
New research analyzed data from 11 studies of over 5,000 women around the world between 1980 and 2021, to evaluate how common it is to get pregnant naturally after having a baby conceived by fertility treatment. Around 20% of women who needed fertility treatment, such as IVF, to conceive their first child are likely to get pregnant naturally in the future, finds a new study.
Published Scientists discover new embryonic cell type that self-destructs to protect the developing embryo (via sciencedaily.com) Original source
Scientists have uncovered a new quality control system that removes damaged cells from early developing embryos.
Published Pregnancy hormone repairs myelin damage in MS mouse model (via sciencedaily.com) Original source
A new study has identified a treatment that could repair myelin in the cortex, undoing some of the damage caused by MS.
Published Technique restores healthy bacterial balance in C-section babies (via sciencedaily.com) Original source
Newborns delivered by cesarean section who are swabbed with the vaginal fluid of their mothers after birth have beneficial bacteria restored to their skin surface and stools, according to a new study. In the first randomized study of its kind, a team of researchers found the process, known as vaginal seeding, definitively engrafted new strains of maternal bacteria in the babies' bodies.
Published New diagnostic finds intact sperm in infertile men (via sciencedaily.com) Original source
Researchers develop new diagnostic tool to visualize protein biomarkers of well-developed sperm to determine if surgical sperm extraction may be successful for certain infertile men.
Published New research identifies cells linking chronic psychological stress to inflammatory bowel disease (via sciencedaily.com) Original source
For the first time, cells involved with the communication between stress responses in the brain and inflammation in the gastrointestinal (GI) tract have been identified in animal models. Glial cells, which support neurons, communicate stress signals from the central nervous system (CNS) to the semi-autonomous nervous system within the gastrointestinal (GI) tract, called the enteric nervous system (ENS). These psychological stress signals can cause inflammation and exacerbate symptoms of inflammatory bowel disease (IBD).
Published Exposure to 'forever chemicals' during pregnancy linked to increased risk of obesity in kids (via sciencedaily.com) Original source
Exposure to per- and polyfluoroalkyl substances (PFAS) during pregnancy was linked to slightly higher body mass indices and an increased risk of obesity in children, according to a new study.
Published Labor induction doesn't always reduce Caesarean birth risk or improve outcomes for term pregnancies (via sciencedaily.com) Original source
Findings conflict with previous national trial results: Women who underwent elective induction were more likely to have a cesarean birth compared with those who underwent expectant management (30% versus 24%.)
Published Impact of maternal stress during pregnancy on child's health (via sciencedaily.com) Original source
New research examines the impact that maternal stress during pregnancy has on the neuro-development of babies.
Published Study gives insight into cause of severe inflammatory bowel disease (via sciencedaily.com) Original source
Investigators have identified a genetic variant that increases people's risk of developing perianal Crohn's disease, the most debilitating manifestation of Crohn's disease. The variant generates changes to DNA that lead to a loss of protein function, which in turn, alters how the body recognizes and handles bacteria, making it less effective at fighting infections.
Published Drinking alcohol while breastfeeding impacts health of newborns (via sciencedaily.com) Original source
What are the consequences of mothers consuming alcohol while breastfeeding? A research team at the University of California, Riverside, performed a mouse study to find out.
Published Exposure to air pollution during pregnancy increases risk for flu (via sciencedaily.com) Original source
A new study shows that exposure to ultrafine particles (UFPs) during pregnancy enhances respiratory viral infection risk. According to the researchers, it is imperative that pregnant women in urban cities, where influenza and UFPs are more prevalent, are provided vaccinations and preventive measures limiting UFP exposure to protect maternal health.
Published Diet high in fruit and vegetables linked to lower miscarriage risk (via sciencedaily.com) Original source
A preconception and early-pregnancy diet that contains lots of fruit, vegetables, seafood, dairy, eggs and grain may be associated with reducing risk of miscarriage, a new review of research suggests.
Published Early signs that may help predict ADHD risk (via sciencedaily.com) Original source
Information available at birth may help to identify children with higher likelihood of developing ADHD, according to new research.
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 Assisted reproduction kids grow up just fine -- but it may be better to tell them early about biological origins, twenty-year study suggests (via sciencedaily.com) Original source
Landmark study finds no difference in psychological wellbeing or quality of family relationships between children born by assisted reproduction (egg or sperm donation or surrogacy) and those born naturally at age 20. However, findings suggest that telling children about their biological origins early -- before they start school -- can be advantageous for family relationships and healthy adjustment.
Published Father's alcohol consumption before conception linked to brain and facial defects in offspring (via sciencedaily.com) Original source
Research investigating fetal alcohol syndrome (FAS) exclusively examines maternal alcohol exposure. However, because men drink more and are more likely to binge drink than women, scientists set out to challenge the existing dogma, using a mouse model to examine what happens when the mother, father and both parents consume alcohol.
Published Time-restricted fasting could cause fertility problems (via sciencedaily.com) Original source
Researchers have found that time-restricted fasting could cause fertility problems. Time-restricted fasting is an eating pattern where people limit their food consumption to certain hours of the day. It's a popular health and fitness trend and people are doing it to lose weight and improve their health. But the new study shows that time-restricted fasting affects reproduction differently in male and female zebrafish. Importantly, some of the negative effects on eggs and sperm quality can be seen after the fish returned to their normal levels of food consumption. The research team say that while the study was conducted in fish, their findings highlight the importance of considering not just the effect of fasting on weight and health, but also on fertility.
