Large abdominal cutaneous defects may occur in association with complex ventral hernias, trauma, tumor resection, necrotizing infections or septic evisceration. Soft tissue reconstruction of the abdominal wall is performed when there is insufficient adipocutaneous tissue to permit standard, primary closure. A number of reconstructive techniques are available, the choice of which is based on a number of factors, including the size and location of the defect, etiology, and timing of closure. In general, local fasciocutaneous advancement flaps and adjacent tissue rearrangement are the workhorse techniques, followed by regional myocutaneous flaps and free tissue transfers for the most complex and extensive of defects. Herein, we describe our approach to abdominal soft tissue reconstruction, indications, technical nuances, and management of complications.

In this issue of Cellular&Molecular Immunology,Hou and coworkers provide novel insights into glucocorticoid(GC)treatment refractoriness in immune thrombocytopenia(ITP),reporting that myeloid-derived suppressor cells(MDSCs)contribute to GC resistance in ITP via impairments in their glucocorticoid receptor(GR)expression and mitochondrial metabolism[1].

Gr?bner basis theory for parametric polynomial ideals is explored with the main objective of mimicking the Gr?bner basis theory for ideals. Given a parametric polynomial ideal, its basis is a comprehensive Gr?bner basis if and only if for every specialization of its parameters in a given field, the specialization of the basis is a Gr?bner basis of the associated specialized polynomial *** various specializations of parameters, structure of specialized ideals becomes qualitatively different even though there are significant relationships as well because of finiteness properties. key concepts foundational to Gr?bner basis theory are reexamined and/or further developed for the parametric case:(i) Definition of a comprehensive Gr?bner basis,(ii) test for a comprehensive Gr?bner basis,(iii) parameterized rewriting,(iv) S-polynomials among parametric polynomials,(v) completion algorithm for directly computing a comprehensive Gr?bner basis from a given basis of a parametric ideal. Elegant properties of Gr?bner bases in the classical ideal theory, such as for a fixed admissible term ordering,a unique Gr?bner basis can be associated with every polynomial ideal as well as that such a basis can be computed from any Gr?bner basis of an ideal, turn out to be a major challenge to generalize for parametric ideals; issues related to these investigations are explored. A prototype implementation of the algorithm has been successfully tried on many examples from the literature.

A framework for generating congruence closure and conditional congruence closure of ground terms over uninterpreted as well as interpreted symbols satisfying various properties is proposed. It is based on some of the key concepts from kapur's congruence closure algorithm(RTA97)for ground equations based on introducing new symbols for all nonconstant subterms appearing in the equation set and using ground completion on uninterpreted constants and puri?ed equalities over interpreted symbols belonging to different theories. In the original signature, the resulting rewrite systems may be nonterminating but they still generate canonical forms. A byproduct of this framework is a constant Horn completion algorithm using which ground canonical Horn rewrite systems can be generated for conditional ground *** effcient algorithms for generating congruence closure of conditional and unconditional equations on ground terms over uninterpreted symbols are presented. The complexity of the conditional congruence closure is shown to be O(n*log(n)), which is the same as for unconditional ground *** proposed algorithm is motivated by our attempts to generate effcient and succinct interpolants for the quanti?er-free theory of equality over uninterpreted function symbols which are often a conjunction of conditional equations and need additional simpli?cation. A completion algorithm to generate a canonical conditional rewrite system from ground conditional equations is also presented. The framework is general and ?exible and is used later to develop congruence closure algorithms for cases when function symbols satisfy simple properties such as commutativity, nilpotency, idempotency and identity as well as their combinations. Interesting outcomes include algorithms for canonical rewrite systems for ground equational and conditional theories on uninterpreted and interpreted symbols leading to generation of canonical forms for ground terms, constrained terms and Horn equat
