“It’s encouraging to see this substantial decline in e-cigarette use among high schoolers within the past year, which is a win for public health,” said Brian King, Ph.D., M.P.H., director of the FDA’s Center for Tobacco Products. “But we can’t rest on our laurels. There’s more work to be done to build on this progress.”… Read More »
Clustering method can better describe the pathological process in patients with traumatic brain injury
Monitoring brain injury biomarkers and glucose variation in patients who have suffered an acute cranial injury during the entire first week of hospitalisation can provide a more accurate picture of the pathological process. This is according to a paper by researchers at Karolinska Institutet in Sweden published in The Lancet Neurology. It is hoped that… Read More »
Novel C. diff structures are required for infection, offer new therapeutic targets
Iron storage “spheres” inside the bacterium C. diff — the leading cause of hospital-acquired infections — could offer new targets for antibacterial drugs to combat the pathogen. A team of Vanderbilt researchers discovered that C. diff (Clostridioides difficile) produces the spheres, called ferrosomes, and that these structures are important for infection in an animal model.… Read More »
Post-Menopausal Sleep Deprivation Raises Type 2 Diabetes Risk
Most individuals tend to sleep for seven hours at a time, but seven to nine hours is the ideal amount of sleep. Sleeping for less than six hours can raise your risk of developing associated disorders. period. The effects were more severe in postmenopausal women, reaching up to 20.1% ( ). The women’s insulin and… Read More »
Focus groups can work without a moderator, shows research
Focus groups that feed views, experiences and opinions into politics, business and research might yield more open interaction and discussion within groups by moving moderators to a separate room, shows new research. The study developed and tested a novel ‘remotely-moderated’ focus group method where questions are posed on a screen, and moved along by a… Read More »
Scientists piece together DNA repair pathway implicated in breast, ovarian, and prostate cancers
Our DNA is not indestructible. Throughout the course of our lives, DNA can break in response to natural and environmental factors. Thankfully, our bodies have dedicated enzymes and pathways which can glue our broken DNA back together through several different mechanisms, known as DNA repair pathways. Some cancers, however, can hijack these pathways for their… Read More »
Apple Health Offers Pioneering Insights into Glucose Control
This year, researchers from Harvard’s Brigham and Women’s Hospital and Harvard’s T.H. Chan School of Public Health collaborated on a study update that evaluates the effects of physical activity and the menstrual cycle on glucose.Released on the World Diabetes Day that was observed on Tuesday, the analyses used data from both the Apple heart and… Read More »
Can gene expression predict if a brain tumor is likely to grow back?
doctors often prescribe radiation along with surgery to treat a brain tumor called meningioma that originates in the protective membranes surrounding the brain. But side effects from radiation can be serious, including memory loss and cognitive decline, so it’s important to know which patients really need it. Now, researchers at UC San Francisco and Northwestern… Read More »
Scientists 3D-print hair follicles in lab-grown skin
A team led by scientists at Rensselaer Polytechnic Institute has 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. The finding, published in the journal Science Advances, has potential… Read More »
Which Influences More Gene Changes in the Brain?
This animal study was conducted by researchers at Ohio State University and presented at Neuroscience 2023, the annual meeting of the Society for Neuroscience ( ). 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. It’s already known… Read More »
Genetic testing could greatly benefit patients with depression, save health system millions
A special kind of genetic test that helps determine the best antidepressant for patients with moderate-to-severe depression could generate substantive health system savings and greatly improve patient outcomes, according to new research from the University of British Columbia. The study, published today in CMAJ, shows that in B.C. alone, implementing pharmacogenomic testing could save the… Read More »
How tiny hinges bend the infection-spreading spikes of a coronavirus
A coronavirus uses protein “spikes” to grab and infect cells. Despite their name, those spikes aren’t stiff and pointy. They’re shaped like chicken drumsticks with the meaty part facing out, and the meaty part can tilt every which way on its slender stalk. That ability to tilt, it turns out, affects how successfully the spike… Read More »
Your Lifestyle May Impair Fertility
“The major problem is that we don’t know the causes of male infertility, and current diagnoses and treatment (are) not causal-based,” said Sarah Kimmins, a Université de Montréal professor and member of the research group. “It’s a one size fits all.” There are limited therapeutic options for infertile guys, she adds, and the diagnosis is… Read More »
How teachers would handle student violence against educators
For the first time, teachers in a nationwide study have told researchers what strategies they think work best to deal with student violence against educators. Teachers rated suspending or expelling students as the least effective way of addressing violence, despite the popularity of “zero tolerance” policies in many school districts. Instead, teachers rated prevention policies,… Read More »
Ultrafine particles from traffic disturb human olfactory cell function
Exposure to ultrafine particles from traffic alters the expression of many genes in human olfactory mucosa cells, a new study shows. The study, led by the University of Eastern Finland, is the first to combine an analysis of emissions from different diesel fuels and exhaust after-treatment systems with an examination of their effects in a… Read More »
India Secures Second Place in Global Diabetes Estimates
India also has 315 million people with high blood pressure. Diabetes is a chronic disease that is caused when pancreas does not produce enough insulin or body cannot use the insulin it produces. It can be treated and prevented by diet, exercise and medications. Every year, World Diabetes Day is observed on November 14 to… Read More »
Reducing systolic blood pressure to less than 120 mm Hg reduced cardiovascular event risk
An intensive three-year intervention to lower the top blood pressure number to less than 120 mm Hg was more effective at preventing death, heart attack, stroke and other cardiovascular events in adults at high risk for cardiovascular disease, compared to the standard treatment target of under 140 mm Hg, according to late-breaking science presented today… Read More »
Hormonal contraceptives in teens may alter risk assessment, rat study suggests
Hormonal contraceptives taken by adolescents may influence development of the brain in a way that alters the recognition of risks, a new study in rats suggests. Scientists at The Ohio State University are exploring how common synthetic hormones used for birth control affect the prefrontal cortex, an area of the brain that continues to develop… Read More »
Do Hormonal Contraceptives in Teens Shape Altered Risk Assessment?
The researchers found that myelination, the formation of protective coating on axons projecting from the main body of brain cells, increased in rats given hormonal birth control compared to untreated rats, while the number of immune cells of the brain decreased. In behavior tests, the treated rats also showed signs of impulsivity. “We start the… Read More »
Early-life stress changes more genes in brain than a head injury
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. It’s already known that… Read More »
