A study of 200 type 1 diabetic patients found a significantly higher mortality rate among African Americans, due largely to acute complications. The results suggest an inadequacy in care for African Americans with type 1 diabetes, potentially linked to issues such as access to care and education.
The Johns Hopkins University Applied Physics Laboratory (APL) successfully conducted the first ground test of a full-scale, fully integrated hypersonic cruise missile engine using conventional liquid hydrocarbon fuel. The Dual Combustion Ramjet (DCR) engine concept demonstrated robust engine operation at speeds up to Mach 6.5.
A study found that lipid-lowering therapy may not be effective in arresting or reversing CAD in one out of four patients, highlighting the need for personalized medical management. PET MPI can help identify treatment failure and guide tailored treatment strategies.
The UC Davis Community Partnerships with Pediatricians for Healthy Children program provides medical residents a grassroots experience in disadvantaged neighborhoods. The program, funded by the $1.8 million Dyson Foundation grant, links residents with community collaboratives to identify and solve health issues.
A one-year study found that a diet reducing fat and calories, combined with walking, led to an average weight loss of 8.5% and improved blood sugar levels. Exercise was reported as the most beneficial behavior among participants.
Researchers used two techniques to examine the electronic structure of magnesium diboride, revealing interactions between electron holes that contribute to its superconductivity. The findings provide new insight into the material's properties and may lead to improved magnetic resonance imaging and electric power transmission.
The study found that while the CT and HPET images could be co-registered within 2mm in centrally located tumor inserts, tumor inserts on the peripheral were only 8-10mm due to distortion and resolution loss of HPET images. This made it difficult for a therapist to refine treatment volume using the co-registered HPET/CT images.
Research found that heavy drinkers exhibit a 'biphasic' response to alcohol, experiencing increased stimulation and euphoria during rising blood alcohol concentrations, but sedation and fatigue during declining levels. In contrast, light drinkers showed only sedation and no positive mood changes.
A study using PET/CT scans found that 58.8% of patients had at least one positive focus of FDG uptake in the thoracic aortic wall, which may indicate 'vulnerable' plaque. This could lead to future cardiovascular events if left untreated.
The study found that higher initial FDG uptake in tumor was associated with poorer prognosis in osteosarcoma patients. Patients identified as having high FDG uptake could be treated more aggressively to improve outcomes.
A recent study by Seth Pollak found that children who have experienced physical abuse categorize facial expressions differently than non-abused children. Abused children identified more faces as being 'angry' rather than fearful or sad. This suggests that experience can shape how people perceive and understand emotions.
Researchers found that male and female rats selectively bred for high and low sensitivity to alcohol also exhibited differences in their response to nicotine. The study suggests that genetic factors may contribute to the co-occurrence of these two substances in individuals, highlighting the need for further research on this topic.
A new UNC study finds that Hispanic men become obese 2.5 times faster than U.S. men of European ancestry, while black women become obese more than twice as fast as white women. The study also shows that the prevalence of obesity in U.S. adults doubled over 40 years, with 61% now classified as obese or overweight.
A study found that nearly 56% of diabetic patients have stress-induced ischemic defects revealed by SPECT myocardial perfusion imaging, regardless of age or sex. These defects were more prevalent in asymptomatic patients than those with a history of chest pain.
A study found contaminated E. coli bacteria in hot sauces from popular tourist restaurants in Mexico and Texas, increasing the risk of travelers' diarrhea. A simple test can detect peripheral arterial disease by comparing blood pressure in the arm and lower leg.
University of Houston researchers are studying novel filtration membranes that can remove up to 90% of natural organic material from water. Their goal is to design better large-scale filtration systems to improve the quality of drinking water supplies, particularly in areas with contaminated or dirty water sources.
A UGA research team has identified a common bacterium as the cause of white pox disease, killing over 98% of elkhorn coral on some reefs near Key West. The disease is highly contagious and spreads rapidly between reefs, highlighting the impact of environmental changes on marine ecosystems.
A new diagnostic tool, Tc 99m Depreotide, has been shown to detect the source of infection in all patients studied within three hours after injection. This is significantly faster than traditional nuclear imaging tests, which can take up to 48 hours, and offers improved accuracy.
A long-term pediatric AIDS study of over 500 children reveals that cardiac abnormalities may persist in infants born to HIV-positive mothers. The study found that both infected and uninfected children had higher left ventricle mass and lower contractility, but differences dissipated over time.
Researchers have developed a new radioimmunotherapy cancer treatment that has shown significant promise in treating mantle cell lymphoma. The study found that high-dose therapy resulted in complete remission for seven of eight patients, compared to only one of four with low-dose therapy.
A new cellular evolution theory challenges Darwinian assumptions by emphasizing horizontal gene transfer as the driving force behind cellular life's evolution. This process allowed for the acquisition of alien cellular components, including genes and proteins, to promote evolutionary change.
A recent study published by the NIH found that approximately 6-7% of women experience regret after tubal sterilization, with a higher risk for those who have experienced conflict with their husbands. The study also discovered that only 2% of women request reversal of either procedure.
A PET scan study found impaired endothelium-dependent coronary artery vasodilator function in healthy young smokers, indicating increased risk of heart attack and stroke. The study suggests that smoking begins to cause damage much earlier than previously thought, even in those without apparent coronary disease.
A new imaging procedure using a radiotracer has revealed the extent of myocardial tissue injury after a heart attack, even in patients who have been successfully revascularized. The study found that 81% of patients showed persistent cellular damage and 90% had perfusion defects.
A US study found that 26% of men and 28% of women were obese by age 35-37, with black women and Hispanic men at higher risk. Obesity is linked to various health problems, including heart disease, diabetes, and stroke.
Research found that alcoholics exhibit blunted heart-rate responses to public speaking despite similar anxiety levels, indicating a disconnection between perception and physiological response. This impairment may contribute to social functioning and emotional experiences in individuals recovering from severe alcohol dependence.
Researchers at UC Santa Barbara study spider dragline silk's mechanical properties, revealing its elastic and strong nature. The protein unfolds into a modular structure with sacrificial bonds that reform under load, making it a promising material for bulletproof vests, armor, and tethers.
Researchers developed a formula to accurately determine water-use efficiency in typical soils, showing that no-till techniques can improve crop yields while reducing runoff and drainage losses. Soils with higher clay content and greater capacity to retain water produce better results, highlighting the importance of soil type management.
