Researchers discover new target for repairing heart after heart attack

Billions of cardiac muscle cells are lost during a heart attack. The human heart cannot replenish these lost cells, so the default mechanism of repair is to form a cardiac scar.

Finer particulate matter (PM1) and risk of cardiovascular disease

A new study published in the journal Environmental Science & Technology Letters reports that particulate matter smaller than a single micron in diameter, called PM1, is strongly linked to the occurrence of cardiovascular disease (CVD). This is thought to be due to its higher surface area to volume ratio.

Immune system cells facilitate the invasive capacity of glioblastoma

In a study published in Brain Communications, a new Open Access publication of the well-known journal Brain, the team led by Carlos Barcia, researcher at Institut de Neurociències of the Universitat Autònoma de Barcelona, analyzed the role of immune cells in the expansion of glioblastoma, the most aggressive brain tumor.

Protein linked with neurodegenerative diseases may help explore the aggressive behavior of gliomas

A protein typically associated with neurodegenerative diseases like Alzheimer's might help scientists explore how gliomas, a type of cancerous brain tumor, become so aggressive.

Researchers identify potential way to halt age-related macular degeneration

Researchers have successfully treated age-related macular degeneration in mice after finding an unexpected link between the two main forms of the blinding eye disease, the leading cause of vision loss in people 60 and older.

Surgical complications are much more likely in smokers

A new study shows that smoking tobacco puts you at a greatly increased risk for complications after surgery. This includes heart and lung damage, poor wound healing and a higher chance of complications. However, quitting smoking, even as late as 4 weeks before the surgery, improves the chances of having a good post-operative result and fewer complications.

Taking high dose of vitamin D linked lower blood pressure in overweight children

Overweight and obese vitamin D-deficient children who took a relatively high dose of vitamin D every day for six months had lower blood pressure and improved insulin sensitivity than their peers who took a lower dose, according to the results of a UPMC Children's Hospital of Pittsburgh clinical trial reported in The American Journal of Clinical Nutrition.

Raman spectroscopy can be used to diagnose the state of thrombocytes in cardiovascular patients

A team of scientists from Immanuel Kant Baltic Federal University used Raman spectroscopy to study the thrombocytes of patients with cardiovascular diseases and compared their spectra with those of healthy people.

Researchers show existence of particular type of sphincter in the brain's blood supply

Allegedly, they should not exist in the brain, the so-called precapillary sphincters - a kind of squeezing 'muscle clamp' between the larger and smaller vessels of the bloodstream.

Alarming link between marijuana and increased heart risk

Marijuana use is rising steadily across the US as more and more states enact laws making it a legal recreational and medicinal agent. However, a new study underlines the fact that this is, in fact, playing with an unknown substance, which may cause serious bodily harm. The review article, published in the Journal of the American College of Cardiology, shows that more than 2 million adults who currently have heart or vascular disease gave a history of being currently on marijuana products, or having used them in the past.

Blood vessels in women age quicker than men's

A new study shows that blood vessels, including large and small arteries, in women, age much faster in women than in men. This is the first time this finding has been reported. The study, published in the journal JAMA Cardiology in January 2020, will be helpful in showing how women are at a different risk for cardiovascular disease, both with respect to the type and the timing, than men.
