Endoscopic use of EpiFix-dehydrated Human Amnion/Chorion Membrane (dHACM) allograft in patients with Gastric Leak following Sleeve Gastrectomy.

Leak following laparoscopic sleeve gastrectomy is one of the most feared complications and its management can be difficult and frustrating for patients and physicians involved. Using multimodality approach and having variable options to plan management for patients presenting with leak following bariatric surgery can be advantageous for physicians. The use of endoscopic injection of EpiFix-dehydrated Human Amnion/Chorion Membrane (dHACM) allograft can be a novel adjunct in facilitating healing of the leak site by iatrogenic introduction of tissue growth factors, cytokines and building connective tissue matrix.

Flagellar elongation and gene expression in Chlamydomonas reinhardtii.

Lithium (Li(+)) affects the physiology of cells from a broad range of organisms including plants and both vertebrate and invertebrate animals. Although its effects result presumably from changes in gene expression elicited by its interaction with intracellular signal transduction pathways, the molecular mechanisms of Li(+) action are not well understood. The biflagellate green alga Chlamydomonas reinhardtii is an ideal genetic model for the integration of the effects on Li(+) on signal transduction, gene expression, and aspects of flagellar biogenesis.
