CHAPEL HILL, NC - Staphylococcus aureus bacteria are a major cause of serious infections that often persist despite antibiotic treatment, but scientists at the UNC School of Medicine have now discovered a way to make these bacteria much more susceptible to some common antibiotics.
DALLAS, Aug. 14, 2019 -- Stroke survivors who completed group-based aerobic exercise programs similar in design and duration to cardiac rehabilitation programs significantly improved their aerobic endurance and walking ability, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
PHILADELPHIA - Five years ago, David C. Fajgenbaum, MD, MBA, MSc, both a Penn Medicine researcher and patient, tried an experimental treatment on himself based on his laboratory research findings in the hopes of saving his own life. He has been in remission ever since. Now his research is shedding new light on why it worked, paving the way for further testing of a new treatment approach in Castleman disease, a rare and deadly condition with limited options for patients.
NEWTOWN SQUARE, Penn., Aug. 13, 2019 - In addition to cleaning the air and water, forests hold a tremendous amount of sequestered carbon. When trees die and then decay on the forest floor, that carbon is released into the atmosphere, a phenomenon that is one of the drivers of climate change. A first-of-its-kind study by a team that included the United States Department of Agriculture's Forest Service and Purdue University scientists finds that non-native invasive insects and diseases are reducing the amount of carbon stored in trees across the United States.
Family physicians typically don't consider where patients live when assessing their health care needs, despite research that indicates a person's environment can significantly affect their health. Things like access to health care and nutritious food and the quality of housing, education, water and air all play a role in health.
AUSTIN, Texas -- For adults with high blood pressure, greater blood pressure control than what's currently considered standard is associated with fewer adverse changes of the brain, which could mean lower risks of dementia and cognitive impairment, according to new research published in the Journal of the American Medical Association.
Sepsis occurs when the body goes overboard in its attempt to fight off an infection. Immune cells rush in, overreact and wreak havoc on tissues and organs, often resulting in organ failure and death.
Researchers at University of California San Diego School of Medicine recently found that removing the enzyme PHLPP1 improved outcomes in a mouse model of sepsis. PHLPP1 controls many cell behaviors by removing phosphates (small chemical tags) from other proteins. And, it now turns out, PHLPP1 also influences inflammation.
Bottom Line: Intensive blood pressure control among adults with high blood pressure was associated with a smaller increase in brain white matter lesions (a marker of small vessel disease and a risk factor for dementia) compared to standard blood pressure control, although the difference was small. Hypertension is a risk factor for developing white matter lesions. This analysis is a substudy of a randomized clinical of 449 patients with high blood pressure who had initial brain magnetic resonance imaging (MRI) and a follow-up MRI after four years.
In a nationwide study, researchers used magnetic resonance imaging (MRI) to scan the brains of hundreds of participants in the National Institutes of Health's Systolic Blood Pressure Intervention Trial (SPRINT) and found that intensively controlling a person's blood pressure was more effective at slowing the accumulation of white matter lesions than standard treatment of high blood pressure.
NASA's Aqua satellite passed over the Northwestern Pacific Ocean and captured a good shot of the wide, ragged center of circulation in Tropical Storm Krosa.
On Aug. 13 at 12:20 a.m. EDT (0420 UTC), the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite provided a visible image of Krosa that showed a large center of circulation, surrounded by fragmented bands of thunderstorms.
With the help of new technology, the researchers of the University of Turku in Finland have gained more detailed information on the diversity of the human lymphatic system than before. The research results can help to understand the human defence mechanisms on the molecular level even better than before. Several cancers, such as breast cancer and head and neck cancers, spread primarily via the lymphatic system.
The transfer of white blood cells between the lymphatic vessels, lymphoid organs, and blood circulation is the backbone of the human defence mechanism.
Regular exercise is healthy and reduces the risk of cardiovascular disease. Nevertheless, it appears that prolonged and/or intensive exercise can lead to an increase in cardiac biomarkers in the blood, such as the regulatory protein troponin. Troponin is a protein that is present in every heart muscle cell. In the event of damage to the heart, these proteins leak into the blood vessels. An increased troponin concentration in the blood is therefore used to diagnose a heart attack, among other purposes.
PHILADELPHIA -A new large population-based study from the Sidney Kimmel Cancer Center - Jefferson Health shows that novel oral androgen signaling inhibitor therapies are associated with an increased risk of death in patients with pre-existing cardiovascular conditions. The research was published in the journal European Urology.
Baltimore, MD., August. 13 -- The vaginal microbiome is believed to protect women against Chlamydia trachomatis, the etiological agent of the most prevalent sexually transmitted infections (STIs) in developed countries. New research by the University of Maryland School of Medicine (UMSOM) shows how the microbiome can either protect or make a woman more susceptible to these serious infections.
Consuming flavonoid-rich items such as apples and tea protects against cancer and heart disease, particularly for smokers and heavy drinkers, according to new research from Edith Cowan University (ECU).
Researchers from ECU's School of Medical and Health Sciences analysed data from the Danish Diet, Cancer and Health cohort that assessed the diets of 53,048 Danes over 23 years.
