Studies find cardiovascular effects of cigarettes and e-cigarettes to be strikingly similar

Two related studies, one in humans and the other in rats, found that the cardiovascular effects of cigarettes and e-cigarettes are strikingly similar, and these harmful effects on blood vessel function are likely caused by airway irritation due to inhalation of a foreign substance, rather than a specific component of the cigarette smoke or e-cigarette vapor (aerosol), according to new research published today in the American Heart Association's peer-reviewed journal Arteriosclerosis, Thrombosis and Vascular Biology.

Hydrogel bioink can bioprint conduits that mimic the mechanics of native blood vessels

Cardiovascular diseases (CVDs) remain among the leading causes of global morbidity and mortality. In patients with CVD, blood vessels-which transport blood, oxygen, and nutrients-can become constricted or obstructed, leading to numerous complications.
