A Broken Heart After Witnessing a Dying Heart: A Case of Takotsubo Cardiomyopathy.

Takotsubo cardiomyopathy is a form of non-ischemic cardiomyopathy characterized by transient systolic dysfunction. The prevalence of Takotsubo cardiomyopathy has been estimated to be about 2% overall but about 10% amongst women presenting with clinical manifestations of acute coronary syndrome. The overall mechanism of the disease still remains unclear.

A Fistula Where? Left Anterior Descending to Pulmonary Artery Fistula.

Fistulas are abnormal passageways between two organs or vessels that usually do not connect. Coronary artery fistulas occur when one of the coronary arteries is connected to either a heart chamber or another blood vessel. This case presents a coronary artery fistula which may or may not be impacting the patient's heart function.

Cytotoxicity and hemostatic activity of chitosan/carrageenan composite wound healing dressing for traumatic hemorrhage.

Hemorrhage remains a big threat to trauma patients, especially in combat fields. Therefore, we formulated a biocompatible and biopolymer based chitosan/carrageenan composite dressing. This dressing was fabricated using freeze-drying that will serve as a promising material to promote hemostasis and tissue growth required during hemorrhage.

Hemostasis and anti-necrotic activity of wound-healing dressing containing chitosan nanoparticles.

Necrotic tissues are the dead tissues present in the wounded areas, which need to be removed for rapid wound healing. Various biopolymer-based dressings have been exploited to heal infected wounds, but with limited success. In a quest to develop an effective and economic wound dressing, a biodegradable dressing containing chitosan nanoparticles has been successfully developed.
