Component Separation: A Case Report of Hybrid and Synthetic Absorbable Mesh Use for Complex Large Ventral Hernia Reparation.

Ventral abdominal hernias are a common abdominal wall defect in the United States. We present a 50-year-old Caucasian male with a large (>18 cm) abdominal wall defect. An extensive complex abdominal wall reconstruction with advanced bilateral fascial flaps/component separation and repair of the abdominal wall defect was planned to restore the appropriate abdominal wall anatomic contour.

A reliable method for monitoring the microvascular patency of free jejunal transfers in reconstructing the pharynx and cervical esophagus.

Reconstruction of the pharynx and esophagus with revascularized segments of jejunum remains a time-proven entity. Most thromboses and subsequent flap failures have occurred within the first 24 hours after revascularization of the flap. What would therefore be desirable is a safe, proven monitoring system to assess the patency of the microvascular anastomoses and subsequent viability of the transferred bowel segment.

A circadian susceptibility/resistance rhythm for potassium cyanide in male BALB/cCr mice.

Circadian rhythms in mortality and/or survival time following a single intraperitoneal injection of a LD50 of potassium cyanide were studied. In two investigations, different but comparable subgroups of inbred male BALB/cCr mice were treated at 4-h intervals (under conditions standardized for chronobiologic study) during 24-h spans. Mice were observed for exact time-to-death during the first hour after treatment as well as overall mortality during the entire 24-h post-injection span following each KCN treatment timepoint.

Human physiological adaptability through the life sequence.

Changes in organ function from birth to old age were investigated from published data. In essence, the observations of Shock and colleagues on maximal breathing capacity, vital capacity, glomerular filtration rate, renal plasma flow, basal metabolic rate (BMR), ulnar nerve conduction velocity, cardiac index, and intracellular water (ICW) for the age period 30 to 85 years were extended to the time of birth. There were two principal findings.
