Highly localized TB strains are less infectious in cosmopolitan cities and more likely to infect people from the geographic area that is the strain's natural habitat. The research provides the first controlled evidence that TB strains may evolve with their human hosts, adapting to be more infectious to specific populations. The findings offer new clues

Strokes lead to irreversible damage to the brain and are one of the most common causes of dependency or death. As the cellular reactions to a cerebral infarction are not yet fully understood, there is a lack of possible approaches to promote the regeneration of damaged nerve tissue in the brain. A new study closes

A new small study has revealed the impact of obesity on muscle structure in patients having a form of heart failure called heart failure with a preserved ejection fraction (HFpEF). A new small study led by Johns Hopkins Medicine researchers and published July 25th in the journal Nature Cardiovascular Research has revealed the impact of

To diagnose heart conditions including heart attacks and heart rhythm disturbances, clinicians typically rely on 12-lead electrocardiograms (ECGs) -- complex arrangements of electrodes and wires placed around the chest and limbs to detect the heart's electrical activity. But these ECGs require specialized equipment and expertise, and not all clinics have the capability to perform them.

Higher levels of urinary metals such as cadmium, tungsten, uranium, cobalt, copper and zinc are linked to increased cardiovascular disease and mortality in a racially and ethnically diverse U.S. population, according to a new study.

A clinical trial suggests that a subset of older adults with a genetic predisposition to Alzheimer's disease may benefit from fish oil supplements. A clinical trial at Oregon Health & Science University suggests that a subset of older adults with a genetic predisposition to Alzheimer's disease may benefit from fish oil supplements. The results come

A nasal COVID-19 vaccine blocks transmission of the virus, according to an animal study. The findings suggest that vaccines delivered directly to the nose or mouth could play a critical role in containing the spread of respiratory infections. The lightning-fast development of COVID-19 vaccines just months after the virus appeared was a triumph of modern

Changes in gene expression in sebaceous glands have now been spatially mapped. The study documents at high resolution changes in gene expression in the course of sebum synthesis and identifies new candidates for the modulation of sebum production. In a collaborative project between the Faculty of Veterinary Medicine and the Interdisciplinary Centre for Bioinformatics (IZBI)

Judging how happy you are could backfire and negatively impact life satisfaction and psychological well-being, according to new research. Judging how happy you are could backfire and negatively impact life satisfaction and psychological well-being, according to research published by the American Psychological Association. In three experiments comprising more than 1,800 participants, researchers found that having

Researchers have developed a way to study aged neurons in the lab without a brain biopsy, allowing them to accurately model the effects of aging in the development of late-onset Alzheimer's disease. By studying these cells, the researchers identified aspects of cells' genomes -- called retrotransposable elements, which change their activity as we age --

High blood pressure affects about 45% of U.S. adults. In the 1970s, only about 50% of patients were aware of their hypertension. Today, 54% are aware of their high blood pressure, 40% are actively treated and 21% are actively controlled. As such, researchers alert health care providers that the old 'silent killer' is alive and

Having high blood pressure, specifically high diastolic blood pressure, was linked to a slightly higher odds of ever having migraine in female participants, according to a new study. Diastolic pressure is when the heart is resting between beats. However, the study did not find an increased risk between other cardiovascular risk factors and migraine. Having
