Published Similarities and differences in human and insect vision formation (via sciencedaily.com) Original source
Researchers have discovered profound similarities and surprising differences between humans and insects in the production of the critical light-absorbing molecule of the retina, 11-cis-retinal, also known as the 'visual chromophore.' The findings deepen understanding of how mutations in the RPE65 enzyme cause retinal diseases, especially Leber congenital amaurosis, a devastating childhood blinding disease.
Published Stress during pregnancy can lead to early maturation of first-born daughters (via sciencedaily.com) Original source
Researchers have found a correlation between early signs of adrenal puberty in first-born daughters and their mothers' having experienced high levels of prenatal stress. They did not find the same result in boys or daughters who were not first-born.
Published Eating too much protein is bad for your arteries, and this amino acid is to blame (via sciencedaily.com) Original source
Consuming over 22% of dietary calories from protein can lead to increased activation of immune cells that play a role in atherosclerotic plaque formation and drive the disease risk, new study showed.
Published Link between high levels of niacin -- a common B vitamin -- and heart disease, study suggests (via sciencedaily.com) Original source
Researchers have identified a new pathway that contributes to cardiovascular disease associated with high levels of niacin, a common B vitamin previously recommended to lower cholesterol. The team discovered a link between 4PY, a breakdown product from excess niacin, and heart disease. Higher circulating levels of 4PY were strongly associated with development of heart attack, stroke and other adverse cardiac events in large-scale clinical studies. The researchers also showed in preclinical studies that 4PY directly triggers vascular inflammation which damages blood vessels and can lead to atherosclerosis over time.
Published Blocking an essential nutrient inhibits malaria parasite growth (via sciencedaily.com) Original source
Researchers found that by preventing the malaria parasite from scavenging fatty acids, a type of required nutrient, it could no longer grow.
Published Why ventilators can be tough on preemie lungs (via sciencedaily.com) Original source
New research finds that premature lungs become stiffer than adult lungs under stress. This disrupts the function of transporters that are important for removing water from the lungs after birth.
Published Heart organoids simulate pregestational diabetes-induced congenital heart disease (via sciencedaily.com) Original source
An advanced human heart organoid system can be used to model embryonic heart development under pregestational diabetes-like conditions, researchers report. The organoids recapitulate hallmarks of pregestational diabetes-induced congenital heart disease found in mice and humans. The findings also showed that endoplasmic reticulum (ER) stress and lipid imbalance are critical factors contributing to these disorders, which could be ameliorated with exposure to omega-3s.
Published Patterns of brain connectivity differ between pre-term and term babies (via sciencedaily.com) Original source
A new scanning study of 390 babies has shown distinct patterns between term and pre-term babies in the moment-to-moment activity and connectivity of brain networks.
Published Pregnant women should avoid ultraprocessed, fast foods, experts urge (via sciencedaily.com) Original source
Research shows that phthalates, a class of chemicals associated with plastics, can shed from the wrapping, packaging and even from plastic gloves worn by food handlers into food. Once consumed during pregnancy, the chemicals can get into the bloodstream, through the placenta and then into the fetal bloodstream. The chemical can cause oxidative stress and an inflammatory cascade within the fetus, researchers noted. Previous literature has indicated that exposure to phthalates during pregnancy can increase the risk of low birth weight, preterm birth and child mental health conditions such as autism and ADHD.
Published Researchers make progress toward developing blood tests for psychiatric and neurological disorders (via sciencedaily.com) Original source
Researchers used genetic material from human blood and lab-grown brain cells say they have made progress in developing a blood test to identify disease-associated changes in the brain specifically linked to postpartum depression and other psychiatric and neurological disorders.
Published Males born to obese mothers more likely to suffer health issues as adults (via sciencedaily.com) Original source
Males born to obese women are more likely to be overweight at birth and develop metabolic complications in later life, including liver disease and diabetes.
Published Polycystic ovary syndrome tied to memory, thinking problems (via sciencedaily.com) Original source
People with polycystic ovary syndrome may be more likely to have memory and thinking problems in middle age, according to new research. The study does not prove that polycystic ovary syndrome causes cognitive decline. It only shows an association.
Published Archaeological evidence of seasonal vitamin D deficiency discovered (via sciencedaily.com) Original source
Rickets ran rife in children following the Industrial Revolution, but new research has found factory work and polluted cities aren't entirely to blame for the period's vitamin D deficiencies.
Published Brain protein's virus-like structure may help explain cancer-induced memory loss (via sciencedaily.com) Original source
In a rare but serious complication of cancer, the body's own immune system can start attacking the brain, causing rapid-onset memory loss and cognitive deficits. What triggers this sudden biological civil war was largely unknown. Now, researchers have found that some tumors can release a protein that looks like a virus, kickstarting an out-of-control immune reaction that may damage brain cells.
Published Maternal pulse recording during childbirth prevents encephalopathy in newborn babies (via sciencedaily.com) Original source
External heart rate monitoring, the most common method of monitoring the fetus, may leave signs of fetal hypoxia undetected if the maternal pulse rate is not simultaneously monitored. The risk is that the fetal heart rate is masked by the maternal pulse, with fetal distress going unnoticed.
Published Rare disorder causing extra fingers and toes identified (via sciencedaily.com) Original source
A rare disorder which causes babies to be born with extra fingers and toes and a range of birth defects has been identified in new research. The disorder, which has not yet been named, is caused by a genetic mutation in a gene called MAX. As well as extra digits -- polydactyly -- it leads to a range of symptoms relating to ongoing brain growth, such as autism. The research marks the first time this genetic link has been identified.
Published Provides new explanation for why placenta may not properly separate at birth, putting mother and newborn at risk (via sciencedaily.com) Original source
A new study may change the way clinicians and scientists understand, diagnose and treat placenta accreta spectrum disorder, a serious condition in which the placenta fails to separate from the uterus at birth, jeopardizing the life and health of both mother and baby.
Published Gene behind heart defects in Down syndrome identified (via sciencedaily.com) Original source
Researchers have identified a gene that causes heart defects in Down syndrome, a condition that results from an additional copy of chromosome 21. Reducing the overactivity of this gene partially reversed these defects in mice, setting the scene for potential future therapies for heart conditions in people with Down syndrome.
Published Ultrasounds can help predict the risk of preterm births (via sciencedaily.com) Original source
Researchers have developed a way to use ultrasound to predict whether a pregnant person is at risk of delivering a baby prematurely, which occurs in upward of 10% of pregnancies in the U.S.
Published Exposure to flame retardants linked to premature birth, higher birth weight (via sciencedaily.com) Original source
Exposure to organophosphate ester flame retardants during pregnancy is linked to premature births and greater fetal growth, according to a new study.
