Caution needed when prescribing antibiotics to hypertension patients, study finds

A new rat study suggests that individual variations in genetic makeup and gut bacteria may explain the different effects of antibiotics on blood pressure. The researchers treated two strains of rats with three common antibiotics, resulting in distinct responses in systolic and diastolic blood pressure. These findings highlight the impo...

Handheld probe images photoreceptors in children

Duke University researchers have developed a handheld probe that can image individual photoreceptors in the eyes of infants, allowing for early detection of eye diseases and brain-related traumas. The new technology uses adaptive optics and is much smaller and faster than previous systems, making it ideal for imaging young children.

Pay attention to the 'noise' in your brain

A recent study published in Nature Communications found that variability in neural responses is not just random noise, but rather due to fluctuations in internally generated signals like attention. This discovery has significant implications for understanding how our brains work and focus, potentially leading to diagnostic tools for ne...

Japanese encephalitis also affects urban areas

A study by CIRAD researchers found that Japanese encephalitis circulates as intensely in Phnom Penh, Cambodia's capital, as it does in rural areas. Vaccinating children remains the best way to protect humans, while vaccinating sows and controlling mosquitoes can reduce virus circulation.

How healthy is the American diet? The Healthy Eating Index helps determine the answer

The new HEI-2015 evaluates diet quality based on 13 components reflecting aspects of the Dietary Guidelines for Americans. It demonstrates reasonable variation across population subgroups and reflects many dimensions of dietary guidance, suggesting its potential as a tool to understand the influence of total diet quality.

How sleep loss may contribute to adverse weight gain

A new study from Uppsala University found that one night of sleep loss can cause tissue-specific changes in gene expression and metabolism, leading to increased fat accumulation and muscle loss. This may explain why shift work and chronic sleep loss increase the risk of obesity and type 2 diabetes.

Garlic ingredient from the lab bench

Ajoene, a stable organosulfur compound in garlic oil extracts, has similar health-promoting effects to allicin and exhibits anticancer activity. Researchers have developed a total synthesis approach to produce ajoene with improved yields, paving the way for its further evaluation in medicinal research.

Parents' behavior during playtime may affect toddler's weight later on

A study by Penn State researchers found that mothers who engage with their children during playtime and gently guide them to clean up can help toddlers with poor regulation skills maintain a healthy weight. As preschoolers, these children tend to have lower BMIs compared to those with good regulation skills, suggesting that parents' be...

Antimicrobial stewardship programs in dialysis clinics reduce infections, costs

Implementing antimicrobial stewardship programs in out-patient dialysis facilities can significantly reduce infections caused by multidrug-resistant organisms, infection-related deaths, and costs. The programs promote the appropriate use of antimicrobials, leading to a 4.8% reduction in infections and a 4.6% reduction in death rates.
