The device detects cell viability directly and instantly, measuring electrical resistance changes in milliseconds after exposure to a toxic agent. It offers a rapid alternative to traditional fluorescent dye assays for detecting biochemical attacks or monitoring drug toxicity.
A study found that adolescents who see more smoking in movies are more likely to try smoking, with 52% of initiations attributed to movie exposure. Reducing adolescents' exposure to smoking in movies could significantly reduce the number of smokers.
A study of 448 children in New York Head Start preschool programs found that those with high cholesterol at ages 3 and 4 were more likely to have high cholesterol five years later. The study suggests that early intervention and primary prevention can be effective in reducing the risk of coronary heart disease.
A large collection of cases reveals that IVIG treatment can cause strokes in some patients, particularly those with hypertension, diabetes, and a history of cerebrovascular disease. The study found a 0.6% risk of stroke among inpatient IVIG recipients over a four-year period.
Teenagers who view more smoking in movies are almost three times more likely to start smoking compared to those with low exposure. The study found that half of smoking initiation can be attributed to viewing smoking in movies, highlighting the need for policy changes to reduce youth exposure.
Researchers at UT Southwestern Medical Center have partially uncovered the stages in the elimination of viral infections and cancer cells by the human immune system. The study found that natural killer cells and cytotoxic T cells use different mechanisms to kill target cells, with significant differences in their roles and receptor usage.
A recent study by the American Heart Association has linked high fruit and vegetable intake to lower healthcare costs in older age. The study found that middle-aged men who consumed more than 42 cups of fruits and vegetables per month had significantly lower Medicare charges compared to those who consumed less.
A study of rural Hawaiians reveals high smoking rates, particularly among native Hawaiian women, which are attributed to lower socioeconomic status and cultural identity. The research aims to develop targeted anti-smoking strategies tailored to the specific needs of this demographic.
NCAR scientists have developed a new algorithm to predict turbulence using airborne radars, enabling pilots to receive warnings up to 30 seconds in advance. The NCAR Efficient Spectral Processing Algorithm (NESPA) demonstrates an 80% detection rate and low false predictions, showing its feasibility for improving aviation safety.
A study of 250 newly diagnosed patients and 388 healthy individuals found that those with high iron intake were 1.7 times more likely to have Parkinson's disease. The study suggests that eating foods rich in iron and manganese may help prevent the disease.
A comprehensive study reveals that factors such as adhesion, invasion, and translocation determine the degree of illness from Listeria monocytogenes. Understanding these mechanisms could lead to the development of vaccines to prevent food poisoning.
A two-year study compares Chinese immigrant stroke patients to controls, finding reduced stroke risk through improved dietary habits, increased exercise, and better job status. Stressful factors like language barriers also contribute to lower job satisfaction among immigrants.
Researchers at Georgia Tech have developed an oxide system that can produce hydrogen from water vapor and methane at lower temperatures, potentially allowing it to be powered by solar energy. This could provide a lower-cost alternative to traditional reforming processes for small-scale fuel cells in homes or vehicles.
A team of researchers used a computer model to simulate the impact of airbag deployment on pilots wearing night-vision goggles. The study found that minimal distance between the eyes and goggles increased stress on orbital bones, while a protective lens reduced impact force but increased surrounding bone pressure.
A recent study found that Asian Americans are seven times more likely to develop silent myocardial ischemia, a condition where plaque buildup restricts blood flow to the heart. Patients may experience fatigue, shortness of breath or palpitations instead of chest pain, emphasizing the need for awareness and early screenings.
Researchers detected SUDS in French Polynesians, a condition linked to family history and fainting. Treatment with implantable defibrillators can prevent sudden death, but further study is needed.
A recent mouse study identified a compound, NAPVSIPQ, that protects embryos from alcohol-induced toxicity by blocking the effects of ethanol on the L1 cell adhesion molecule. This finding suggests a new target for medication development to prevent fetal alcohol damage.
A study by OSU researchers found that their weather forecasting tool, AMPS, outperformed competing models in predicting extreme weather conditions at the South Pole. This achievement has implications for extending the limited summer research season and improving polar forecasting skills.
A study by University of North Carolina at Chapel Hill researchers found that overall reported sadness returned to pre-incident levels within four to six weeks, while increased trust in national, state and local governments persisted. Young adults between 18 and 26 were more likely to report religious feelings and higher psychological ...
Drs. Chang and Moore were awarded the Mott Prize for their discovery of KSHV, a virus linked to Kaposi's sarcoma, the most common malignancy in AIDS patients. Their work has opened new areas in cancer research and will continue to use innovative techniques to understand KSHV's impact on cancer.
Research found that pollution levels from vehicle traffic vary greatly depending on traffic volume and vehicle type, with larger vehicles emitting up to 60 times more carcinogens than smaller ones. The study suggests that diesel engines power these larger vehicles, exacerbating exposure in urban communities.
Researchers discovered that a lost protein called PEDF can inhibit angiogenesis, a crucial process for tumor growth, in prostate cancer cells. Treatment with PEDF also triggered increased cell death in cancer cells, suggesting its potential as a new treatment option.
A recent study found that nearly 20% of North Carolina children experience un-diagnosed asthma symptoms, leading to missed school days and limited activities. The condition affects not only physical health but also sleep patterns, cognitive function, and learning ability.
A new study found that transferred patients are sicker and more likely to die than those admitted directly, damaging hospital scores on measures used by patients, insurers, and employers. The 'transfer effect' must be accounted for in hospital benchmarking tools to ensure accurate representation of quality care.
The XPERT TM study shows Xyzal significantly improved symptoms and quality of life for patients with persistent allergic rhinitis. Long-term treatment reduced co-morbidity, lost productivity, and economic savings.
A recent study by Ohio State University anthropologist Jeffrey McKee predicts that the United States will face a significant threat to global biodiversity within 50 years, with at least 10 additional species added to the threatened list. The prediction is based on a model that separates human population growth from environmental impact...
Researchers have developed a method to extend the shelf life of cultured fetal neural stem cells, enabling the generation of enough cells to treat diseases like Parkinson's and ALS. The study characterized long-term neural stem cell lines using gene chip analysis, which may help create customized cells for therapy.
