INTRODUCTION Treatment of heterotopic ossification (HO) of the elbow is challenging and fraught with complications. Patients who sustain direct trauma to the elbow joint, the central nervous system, and thermal burns are at increased risk for development of HO. There is a paucity of studies and reports on patient's self-evaluation after the excision of the heterotopic ossification. MATERIALS ...

The high incidence of female obesity and weight loss has resulted in common complaints of a large, protuberant mons pubis and labia majora (outer labial lips) related to unsightly fat deposits and skin ptosis. The author presents a technique to correct the protuberant mons and pubic descent by performing a pubic lift, fat excision, and liposuction, and then tacking the superficial fibrofatty ti...

control of well drilling operations poses a challenging issue to be tackled. the loss of well control could lead to the occurrence of blowout as a severe threat, involving the risk of human lives and environmental and economic consequences. conventional proportional-integral (pi) controller is a common practice in the well control operation. the small existing margin between pore pressure and f...

Abstract Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production without using SMG is not economically feasible. However, SMGs are non-essential once an intact transgenic plant has been established. Eli...

Group I self-splicing intron constitutes an important class of functional RNA molecules that can promote chemical transformation. Although the fundamental mechanism of the auto-excision from its precursor RNA has been established, convenient assay systems for its splicing activity are still useful for a further understanding of its detailed mechanism and of its application. Because some host RN...
