Temporal patterns for inguinal hernia recurrence operations after Shouldice Repair.

Purpose: Shouldice Repair for inguinal hernias results in a low recurrence rate; however, little is known about the risk factors for these relapses. In the present study, we reviewed all patient's undergoing a reoperation for recurrence after a primary Shouldice Repair.

Methods: Patients undergoing recurrent inguinal hernia repair from 2013 to 2017 were identified.

Surgical aspects and early morbidity of patients undergoing open recurrent inguinal hernia repair.

Purpose: This study aims to characterize the patterns of recurrence associated with specific types of primary inguinal hernia repair techniques used for and their respective correlations with early morbidity, in patients undergoing open repair for their first hernia recurrence.

Methods: After ethics approval was obtained, a retrospective review of charts from patients who underwent open surgery for repair of a first recurrence after a previous inguinal hernia repair during 2013-2017 was completed. Statistical analyses were performed and p-values < .

The Shouldice Method: an expert's consensus.

Background: Hernia repairs are a commonly performed surgical procedure and the Shouldice Repair of inguinal hernias has been well described before in terms of its outcomes. However, the purpose of this paper was to understand what experts from Shouldice Hospital consider to be the essential steps to the Shouldice Method.

Methods: Utilizing a Delphi Methodology, surgeons at Shouldice Hospital who are considered content experts, provided their answers on what is essential to the Shouldice Method.

Duplicated phosphoglucose isomerase genes in avocado.

Avocado (Persea americana) cultivars were assayed for phosphoglucose isomerase (PGI) isozymes using starch gel electrophoresis. Three PGI genes were identified: one monomorphic locus, Pgi-I, coding for the plastid isozyme and two independently assorting loci, Pgi-2 and Pgi-3, coding for the cytosolic isozymes. The genetic analysis was based on comparisons of PGI zymograms from somatic and pollen tissue and on Mendelian analysis of progeny from selfed trees.

The formation of enzyme-bound and medium pyrophosphate and the molecular basis of the oxygen exchange reaction of yeast inorganic pyrophosphatase.

Yeast inorganic pyrophosphatase, with 10 mM 32Pi and 10 mM Mg2+ present at pH 7.3 TO 7.6, rapidly forms enzyme-bound pyrophosphate equivalent to about 5% of the total catalytic sties on the two enzyme subunits.

Cyanogen induced phosphorylation of D-fructose.

Cyanogen-induced phosphorylation of D-fructose at pH 8.8 led to the formation of a phosphorylated sugar identified as alpha-D-furcto-pyranose 2-phosphate on the basis of its chromatographic and electrophoretic properties, its lability to hydrolysis by alkaline phosphatase, the rate of its acid-catalysed hydrolysis, the results of periodate oxidation and optical rotatory measurements.

Coupling of "high-energy" phosphate bonds to energy transductions.

Recent results suggest consideration of a new concept for oxidative phosphorylation in which a prime function of energy is to bring about release of ATP formed at the catalytic site by reversal of hydrolysis. Data with submitochondrial particles include properties of an uncoupler insensitive Pi=HOH exchange, a rapid reversible formation of bound ATP in presence of uncouplers, and predictable patterns of 32-Pi incorporation into ATP in rapid mixing experiments. ADP is confirmed as the primary Pi acceptor in mitochondrial ATP synthesis, but with chloroplasts ADP is also rapidly labeled.
