Research shows females use anti-inflammatory T cells to maintain their blood pressure

In the face of a multipronged front to drive blood pressure up, including a high-salt diet, females are better able to keep their pressure down by increasing levels of a T cell that selectively dials back inflammation, scientists say.

Overactive enzyme causes an inherited form of high blood pressure

A Turkish family from a village near the Black Sea first caught the attention of medical researchers in the early 1970s.

'Off-the-shelf' artificial cardiac patch improves heart attack recovery in rat and pig models

Researchers from North Carolina State University have developed an "off-the-shelf" artificial cardiac patch that can deliver cardiac cell-derived healing factors directly to the site of heart attack injury. In a rat model of heart attack, the freezable, cell-free patch improved recovery.

Antioxidant in mushrooms may relieve symptoms of pre-eclampsia

Pregnancy hypertension, or Pre-eclampsia, is a complex disorder of pregnancy. Treatment of elevated blood pressure can manage the condition in the mother, but in severe cases delivery is needed, which can present a major problem to the baby if it is born prematurely.

Researchers investigate methods to 3D bioprint tissues for craniomaxillofacial reconstruction

Seamlessly correcting defects in the face, mouth and skull is highly challenging because it requires precise stacking of a variety of tissues including bone, muscle, fat and skin.

Increasing the number of small blood vessels may be helpful for recovering movement

Many health conditions - ranging from disease of particular organs such as heart and lungs, widespread metabolic issues such as diabetes, or following trauma such as spinal cord injury – cause difficulties with movement.

Potential Parkinson's treatment effectively targets a specific group of brain cells

Scientists have discovered that a non-invasive technique which could one day be used to treat Parkinson's disease, can successfully target a highly specific group of brain cells which play a key role in development of the condition.

Cannabis exposure during pregnancy has measurable impact on placental and fetal growth

A new study from researchers at Western University and Queen's University definitively shows that regular exposure to THC, the main psychoactive ingredient in cannabis, during pregnancy has significant impact on placental and fetal development.

Phototherapy strategy highly effective for treating carbon monoxide poisoning in rats

Carbon monoxide (CO)--which is produced by cars and trucks, as well as fires and explosions--is a toxic, colorless, and odorless gas, and there are more than 50,000 admissions to US emergency rooms due to CO poisoning each year, with many cases involving damaged airways and lungs.

New gene therapy helps stroke patients develop new neurons

Ischemic stroke is a condition in which parts of the brain lose their blood supply, causing nerve damage. Once brain tissue suffers irreparable harm, the patient will experience irreversible disability or death, depending on the extent of neuronal loss.

Inflammation in the lungs triggers silent mutation to cause pulmonary hypertension

Researchers at the Stanford University School of Medicine have found that inflammation in the lungs of rats, triggered by something as simple as the flu, may wake up a silent genetic defect that causes sudden onset cases of pulmonary hypertension, a deadly form of high blood pressure in the lungs.

Traumatic brain injuries could be healed using peptide hydrogels

Traumatic brain injury (TBI) –– defined as a bump, blow or jolt to the head that disrupts normal brain function –– sent 2.5 million people in the U.S. to the emergency room in 2014, according to statistics from the U.S. Centers for Disease Control and Prevention.
