Python a 'hearty' eater

... blood-pumping organ. In experiments, the python's ventricle increased in mass by 40 percent within 48 hours. Unlike a human heart, which has two ventricles or pumping chambers, a reptile heart has only one. "In mammals, including humans, a 10-30 percent increase in ventricular mass can occur following sever...

Implantable pumps extend lives of patients too sick for transplant

...evices (LVADs), are employed when the heart's left ventricle ?the chamber of the heart that pumps blood throughout the body ?is too weak to pump enough blood to nourish the body's tissues. LVADs have been used as successful short-term "bridges to heart transplant" and are increasingly being considered as a lon...

Whole-genome study at Johns Hopkins reveals a new gene associated with abnormal heart rhythm

So NOS1AP is active in the right place and time to play a role in QT interval. Further studies revealed that approximately 60 percent of peopl...
