Temple researcher receives NIH award to study the link between HIV, substance use and heart disease

With prompt diagnosis and the right treatment, people with HIV can live long, healthy lives. In recent years, however, gains in survival among people with HIV have exposed a new concern – an increase in the incidence of early-onset cardiovascular disease associated with long-term HIV.

Discovery could lead to a simple screening process for predicting heart attack risk

Combining information about the pattern of blood vessels in the retina with genetic data can enable accurate prediction of an individual's risk of coronary artery disease (CAD) and its potentially fatal outcome, myocardial infarction (MI), commonly known as a heart attack.

Alternative remedy to conventional root canals would regenerate lost tooth pulp

Each year, dentists in the United States perform more than 15 million root canals on infected teeth, removing the inflamed pulp and filling the emptied canal with inert materials such as rubber and cement. What remains is a mineral shell in place of a living tooth.

Gratitude expressions within work environments improve teammates’ cardiovascular stress responses

A study from the University of California San Diego's Rady School of Management finds teammates who thanked each other before performing a high-stress task had a better cardiovascular response compared to teams who did not express gratitude.

Ultrasound localization microscopy can image microscopic vessels and measure blood flow in the brain

To image microscopic vessels and measure blood flow in the brain, researchers use a tool called ultrasound localization microscopy. It works by using microscopic bubbles circulated through the bloodstream as a contrast agent to measure the reflection of high-frequency acoustic waves passing through the body.

Study uncovers a possible mechanism that links cerebrovascular disease and Alzheimer's

For more than 20 years, scientists have known that people with hypertension, diabetes, high cholesterol, or obesity have a higher likelihood of developing Alzheimer's disease.

The enigma of post-acute infection syndromes

In a recent review published in the journal Nature Medicine, researchers summarized known literature findings of the unexplained post-acute infection syndromes (PAISs).

Allergic asthma, allergies may be associated with the risk of cardiovascular diseases

When most people think of cardiovascular diseases (CVD), risk factors such as high blood pressure, high cholesterol, obesity, and diabetes likely come to mind.

Mathematical modeling reveals important factors that govern the effectiveness of adaptive therapy

Most cancer treatments are based on using the maximum tolerated dose of a drug to kill as many cancer cells as possible.

Study reveals underlying signaling pathway that results in pulmonary arterial hypertension

Pulmonary arterial hypertension (PAH) is a type of high blood pressure in the lungs, in which blood vessels are narrowed, blocked or destroyed, causing the heart to work harder and, in time, result in cardiac weakness and failure.

Liposomes tailored for pulmonary delivery for treating acute respiratory distress syndrome

Researchers developed 1,2-dimpalmiyristoyl-sn-glycero-3-phosphocholine liposomes co-loaded with methylprednisolone and N-acetyl cysteine to treat acute respiratory distress syndrome in vivo.

Researchers develop new cranial window system for long-term studies of brain activity

Bilal Haider is studying how multiple areas of the brain work together for visual perception. This could help researchers understand if neural activity "traffic jams" underlie all kinds of visual impairments: from running a red light when visual attention is elsewhere, to shedding light on the autism-affected brain.
