A team of researchers has developed a 'time bomb' nanocontainer that releases vasodilator content exclusively to diseased areas, increasing treatment efficacy and reducing side effects. This technology exploits the physical phenomenon of shear stress in stenosed arteries to deliver targeted therapy.
New studies find insufficient data to draw conclusions on whether same-sex parenting disadvantages children. A review and new study reveal differences in social and emotional well-being between young adults raised by women with same-sex relationships and those in nuclear families.
Researchers have developed a simple blood test that can identify patients who will not respond to the painkiller tramadol. The test measures the ratio of tramadol's metabolite O-demethyltramadol (ODT) to tramadol itself, allowing doctors to switch non-responding patients to alternative painkillers like morphine.
Researchers at Oregon State University used data from underwater hydrophones and seismic analysis to detect an abrupt spike in energy about 2.6 hours before the eruption, suggesting a new method for predicting undersea volcanic activity. The study also revealed insights into the link between magma intrusion and seafloor deformation.
Researchers found that pre-operative aspirin therapy can halve the risk of post-operative acute kidney failure. The study involved 3,219 patients and showed a significant decrease in incidence of acute renal failure with aspirin use.
A 25-year study in Northern Sweden found that a switch to low-carbohydrate diets after reducing fat intake led to an increase in cholesterol levels, indicating a higher cardiovascular risk. Despite initial success in reducing cholesterol levels through dietary changes, the population's BMI continued to rise over time.
Researchers identified distinct cancer signatures linked to treatment response in breast tumors, which could help personalize treatment for patients. The study found mutations in genes like TP53 and MAP3K1 associated with good response to aromatase inhibitors, while others like MALAT1 predicted poor outcomes.
Research using fMRI scans found that sleep loss significantly amplifies anticipatory activity in deep emotional brain centers, especially the amygdala. Participants who were more anxious showed the greatest vulnerability to the aggravating effects of sleep deprivation.
Researchers have developed chemical compounds that selectively block the attachment of sugar molecules to cells, potentially leading to new treatments for chronic inflammation, autoimmune diseases, and cancer. The new tools can help scientists understand how glycans influence cell function and behavior.
A study using MRI scans found that sleep deprivation disrupts the higher brain areas responsible for making food choices, rather than basic reward centers. This impairment may explain the link between sleep loss and obesity.
A recent study using brain scans found that sleep-restricted individuals exhibit a distinct neural response to unhealthy foods, activating reward centers more intensely than those with adequate sleep. This response is associated with increased consumption of fattening foods after sleep restriction.
University of Montreal researchers developed a strategy to monitor protein assembly by integrating fluorescent probes throughout the linear protein chain. This approach enables capturing snapshots of protein shape at each stage of assembly, shedding light on how proteins self-assemble into working nanomachines.
Scientists have identified four new genes that predispose people to the most common type of migraine, without aura. The study provides further evidence for the role of molecular signaling in migraine and opens new avenues for research into its causes.
Researchers have imaged S-layer of Geobacillus stearothermophilus bacterium down to atomic scale, revealing chainmail-like structure that provides tough yet flexible protection and allows nutrients to diffuse in and out. This discovery holds promise for developing new vaccines by exploiting the ability of S-layers to self-assemble.
The Hypoglycemia-Hyperglycemia Minimizer (HHM) System successfully detects blood glucose highs and lows, automatically adjusting insulin delivery to safely manage type 1 diabetes. The study's findings lay the groundwork for further clinical trials and a potential game-changer for millions living with the condition.
Scientists have discovered that the controlled release of microRNA miR-675 slows down placental growth before birth, regulating a key factor in healthy pregnancy. This finding has important implications for understanding how environmental signals and diet may influence fetal development.
