in this paper we establish a characterization of abelian compact hausdorff semigroups with unique idempotent and ideal retraction property. we also introduce a function algebra on a semitopological semigroup whose associated semigroup compactification is universal withrespect to these properties.

Distal-less function Distal-less (Dll), as its name suggests, is required for distal limb development. Drosophila mutants lacking Dll function die as embryos because they lack the rudimentary larval limbs (Cohen and Jurgens, 1989). Viable combinations of Dll alleles of increasing severity can be used to generate a phenotypic series in which weak allelic combinations lead to fusions of the dista...

       Background: An intra-articular distal humerus malunion can be disabling. To improve function, reduce pain and/ or prevent further secondary osteoarthritis an intra-articular corrective osteotomy can be considered. Herein we present the indications, practical guidelines for pre- operative planning and surgical technique. Subsequently, we provide long-term results in a small series.   Meth...

Background: Nowadays combined high tibial osteotomy and ACL reconstruction is accepted as a safe and effectivesurgery for patients with symptomatic varus osteoarthritis and anterior knee instability; however, the source of varusdeformity is sometimes the femoral bone. No studies have reported concomitant ACL reconstruction and distal femoralosteotomy in ACL-deficient knees wit...

Background:  Distal femur wedge osteotomies for varus or valgus alignment of the lower extremity could be done in either uniplanar or biplanar fashion.Union time and stability of the osteotomy site has been considered important in this anatomic region. In this study, clinical and radiographic findings of biplane distal femur osteotomy were reported. Methods: Clinical, functional, and radiologic...
