Published Study reveals surprising link between malnutrition and rising antibiotic resistance (via sciencedaily.com) Original source
Researchers have uncovered startling connections between micronutrient deficiencies and the composition of gut microbiomes in early life that could help explain why resistance to antibiotics has been rising across the globe. The team investigated how deficiencies in crucial micronutrients such as vitamin A, B12, folate, iron, and zinc affected the community of bacteria, viruses, fungi and other microbes that live in the digestive system. They discovered that these deficiencies led to significant shifts in the gut microbiome of mice -- most notably an alarming expansion of bacteria and fungi known to be opportunistic pathogens. Importantly, mice with micronutrient deficiencies also exhibited a higher enrichment of genes that have been linked to antibiotic resistance.
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 Vitamin B12: A key player in cellular reprogramming and tissue regeneration (via sciencedaily.com) Original source
Researchers reveal that vitamin B12 significantly boosts the efficiency of cellular reprogramming, thus holding promise for regenerative medicine. Vitamin B12 supplementation shows potential in speeding up tissue repair in a model of ulcerative colitis -- an observation that points to potential new treatments for inflammatory diseases.
Published Early-life stress changes more genes in brain than a head injury (via sciencedaily.com) Original source
A surprising thing happened when researchers began exploring whether early-life stress compounds the effects of a childhood head injury on health and behavior later in life: In an animal study, stress changed the activation level of many more genes in the brain than were changed by a bump to the head.
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 Reducing vitamin B5 slows breast cancer growth in mice (via sciencedaily.com) Original source
Researchers have discovered that breast cancer cells expressing a cancer-driving gene heavily rely on vitamin B5 to grow and survive.
Published Why we don't all develop posttraumatic stress disorder after trauma (via sciencedaily.com) Original source
Researchers show why only a subset of individuals exposed to trauma develop posttraumatic stress disorder (PTSD). The research, centered on the body's stress hormone response, could pave the way for more targeted treatments for PTSD.
Published New clues to the mechanism behind treatment-resistant depression (via sciencedaily.com) Original source
Major depressive disorder (MDD) is a widespread mental health condition that for many is disabling. It has long been appreciated that MDD has genetic as well as environmental influences. In a new study researchers identify a gene that interacted with stress to mediate aspects of treatment-resistant MDD in an animal model.
Published Study indicates possible link between chronic stress and Alzheimer's disease (via sciencedaily.com) Original source
Researchers have published a study that addresses possible associations between chronic stress, mild cognitive impairment and Alzheimer’s disease. The study shows how people aged between 18 and 65 with a previous diagnosis of chronic stress and depression were more likely than other people to be diagnosed with mild cognitive impairment or Alzheimer’s disease.
Published Posttraumatic brain activity predicts resilience to PTSD (via sciencedaily.com) Original source
After a traumatic experience, most people recover without incident, but some people -- between 2% and 10% -- develop posttraumatic stress disorder (PTSD), a mental health condition that can cause debilitating symptoms of anxiety due to emotional dysregulation. PTSD symptoms are present in up to 40% of trauma survivors in the acute aftermath of trauma, but full-blown PTSD develops in only a small subset of cases. Early identification of those at risk is critical for both early treatment and possible prevention.
Published Your body's own cannabinoid molecules calm you during stress (via sciencedaily.com) Original source
When you're under stress, your brain may release its own cannabinoid molecules to calm you, activating the same brain receptors as THC derived from cannabis plants. But the brain activity regulated by these cannabinoid molecules were not well known. A new study in mice has discovered a key emotional brain center, the amygdala, releases cannabinoid molecules under stress that dampen the incoming stress alarm from the hippocampus, a memory and emotion center in the brain. The finding may reveal novel therapeutic targets for the treatment of stress-related disorders.
Published Active children are more resilient (via sciencedaily.com) Original source
The school year has hardly begun and the first exams are already approaching. According to findings by researchers from the University of Basel, school children cope better with the stress if they get plenty of daily exercise.
Published First-in-class targeted microRNA therapy slows cancer tumor growth (via sciencedaily.com) Original source
A new cancer therapy attacks tumors by tricking cancer cells into absorbing a snippet of RNA that naturally blocks cell division.
Published Antioxidants stimulate blood flow in tumors (via sciencedaily.com) Original source
Vitamin C and other antioxidants stimulate the formation of new blood vessels in lung cancer tumors, a new study shows. The discovery corroborates the idea that dietary supplements containing antioxidants can accelerate tumor growth and metastasis.
Published Stress and insomnia linked to irregular heart rhythms after menopause (via sciencedaily.com) Original source
A study of more than 83,000 questionnaires by women ages 50-79, found more than 25% developed irregular heart rhythms, known as atrial fibrillation, which may increase their risk for stroke and heart failure.
Published Do certain amino acids modify the risk of dementia linked to air pollution? (via sciencedaily.com) Original source
Higher levels of vitamin B-related amino acids may be linked to the risk of dementia associated with a certain type of air pollutants called particulate matter, according to a study published in the July 19, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study does not prove that pollution or amino acids cause dementia, but it suggests a possible link among them.
Published High-quality sleep promotes resilience to depression and anxiety (via sciencedaily.com) Original source
Research has shown quality sleep can help bolster resilience to depression and anxiety.
Published Taking higher-than-recommended doses of vitamin D for five years reduced the risk of atrial fibrillation (via sciencedaily.com) Original source
Taking higher-than-recommended doses of vitamin D for five years reduced the risk of atrial fibrillation in older men and women, according to a new study.
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 How chronic stress drives the brain to crave comfort food (via sciencedaily.com) Original source
Stress can override natural satiety cues to drive more food intake and boost cravings for sweets.
