The largest study on the prevalence of polycystic ovary syndrome (PCOS) in the United States found that approximately 6.6% of premenopausal women have PCOS, surpassing previous estimates. This significant increase may be due to a more representative sample size and improved diagnostic methods.
Scientists at NIST effectively turn atoms into better frequency sensors by entangling them, allowing for faster and more accurate measurements in atomic clocks. This technique could reduce the time needed to measure atomic clock ticks from weeks to months.
The 'tango array' device can sort particles ranging from bacterial cells to DNA segments in a matter of seconds, distinguishing them by size. This breakthrough technology has the potential to greatly accelerate biological research and replace some centrifuge devices.
Researchers developed a regulatable gene therapy that can be turned on and off using doxycycline, offering potential for treating Parkinson's disease. The treatment uses the glial cell line-derived neurotrophic factor (GDNF) protein to promote survival and differentiation of dopamine neurons.
A study by UT Southwestern Medical Center researchers found that patients who broke bones in traumatic accidents often experience Post-traumatic Stress Disorder (PTSD), with almost 51% of civilian orthopaedic trauma patients displaying symptoms. The more severe the injury, the higher the likelihood of PTSD.
Over 60% of type 2 diabetes patients fail to meet recommended glucose treatment goals, increasing risk of complications such as heart disease and blindness. The Control to Goal initiative aims to bridge the gap between guidelines and clinical practice, promoting better diabetes management.
Researchers found that condensin proteins cause DNA to extend in stepwise 'clicks' like Velcro unzipping, with the process reproducing identically every time. The energy-containing molecule ATP plays a regulatory role, allowing the bound protein to recondense DNA when tension is lowered
Researchers found that older adults who pictured testing their blood sugar were 50% more likely to do so regularly compared to those using other memory techniques. The study's findings suggest that imagination may be a powerful and inexpensive technique for improving medication adherence in older adults.
A study found that men and women have distinct answers when asked about their favorite outdoor activities, with women often citing family-oriented pursuits. This suggests that traditional questionnaire structures may not account for differences in how men and women interpret questions about outdoor recreation preferences and behavior.
A study published by Temple University researchers debunks the longstanding 'Trojan Horse' model of HIV-caused dementia. They found that a large, late invasion of HIV-infected macrophages into the brain is responsible for the disease, not early latent infection as previously thought.
Dr. Bernard Levin, a colorectal cancer expert, is honored by ASCO for his significant contributions to preventing and managing cancer. He will deliver an acceptance lecture on June 6, highlighting his leadership in multidisciplinary programs in research, service, and education.
A study found that fructose consumption can lead to decreased insulin and leptin levels, increased triglycerides, and lower ghrelin levels, all contributing to weight gain and obesity. The results suggest that frequent fructose consumption may contribute to the development of cardiovascular disease.
