Myokine Probdnf-P75ntr Signaling In Skeletal Muscle Injury And Sterile Inflammation, Katherine Aby

Dissertations and Theses

Originally discovered in the brain, brain-derived neurotrophic factor (BDNF) has been shown to be expressed and released from skeletal muscle as a myokine. However, the function of myokine BDNF is not fully understood. Of interest to this study is the function of the BDNF precursor proBDNF in skeletal muscle. We first show that skeletal muscle expresses unique BDNF splice variants compared to the brain, and at the protein level, skeletal muscle expresses significantly more proBDNF than mature BDNF under basal conditions. Consistent with this, expression of major protein convertases in skeletal muscle were significantly lower. The role of myokine proBDNF …

A Narrative Review On Pathophysiology And The Trends In Preventing Colon Anastomotic Leakage In Animals, Mohammed Albahrawy, Marwa Abass, Esam Mosbah, Gamal Karrouf, Adel Zaghloul

Mansoura Veterinary Medical Journal

Intestinal healing normally proceeds through three stages: the inflammatory, proliferative, and maturation stages. Dehiscence, a disastrous outcome of intestinal anastomosis surgery, usually happens during the inflammatory stage of recovery, when the anastomotic technique (suture or staple line) has the greatest influence on the biomechanical strength of the anastomosis. Because of the severe systemic abnormalities and financial load brought on by septic peritonitis and the need for a second surgery, the ensuing septic peritonitis is linked to an astounding morbidity rate of up to 85%.

Despite the relatively high frequency of anastomosis surgeries, anastomotic leaks pose a deadly risk to colon …
