Bordered Floer homology associates to a parametrized oriented surface a certain differential graded algebra. We study the properties of this algebra under splittings of the surface. To the circle we associate a differential graded 2-algebra, the nilCoxeter sequential 2-algebra, and to a surface with connected boundary an algebra-module over this 2-algebra, such that a natural gluing property is...

A Zn-cornered, mixed-ligand, metal-organic framework (MOF) bearing TMS-protected acetylenes has been constructed and its surface decorated with organic molecules via'click chemistry', in a demonstration of selective post-synthesis functionalization.

BACKGROUND Vermilion irregularities are common secondary deformities after cleft lip repair, regressed or resected hemangiomas, trauma and tumor surgeries. Vermilion deficiency attracts considerable attention and detracts from an otherwise excellent lip repair. Minor and moderate vermilion defects can be corrected with upper lip advancement, rotation flaps, tongue flaps or grafts. Major defect...

BACKGROUND It has been reported that systemic administration of allopurinol improves cell survival. This study was aimed to evaluate effects of allopurinol on skin flaps in dogs. METHODS Twenty dogs underwent one skin flap surgery with a 2-week interval. The first procedure was performed according to the standard protocols. The second phase was started by a 1-week pretreatment with all...

BACKGROUND Reconstruction of upper extremity deformities continues to be a challenge to the reconstructive surgeon. Various loco regional, distant and free flaps are available for reconstruction. However, each has its own set of advantages and disadvantages. Of the commonly performed local flaps, radial artery forearm flap, and the posterior interosseus artery flap stand out prominently. Rec...
