Effects of Teriparatide on Clinical and Radiologic Long-Term Outcomes after Fixation of Pertrochanteric Hip Fractures.

Background: Pertrochanteric hip fractures are common and among serious injuries of the old population with considerable mortality and morbidity. The aim of this study was to evaluate long-term effects of recombinant human parathyroid hormone on postoperative clinical and radiologic outcomes in elderly patients with pertrochanteric hip fractures.

Materials And Methods: Between 2016 and 2019, we prospectively assessed 80 patients with pertrochanteric hip fractures who underwent reduction and internal fixation with a dynamic hip screw.

Strong internal resonance in a nonlinear, asymmetric microbeam resonator.

Exploiting nonlinear characteristics in micro/nanosystems has been a subject of increasing interest in the last decade. Among others, vigorous intermodal coupling through internal resonance (IR) has drawn much attention because it can suggest new strategies to steer energy within a micro/nanomechanical resonator. However, a challenge in utilizing IR in practical applications is imposing the required frequency commensurability between vibrational modes of a nonlinear micro/nanoresonator.

Antipseudomonal -Lactams Resistance in Iran.

Over the last years, the mortality rate of , which is one of the major reasons for severe infections, has been significantly increasing. This bacterium is highly resistant to many antibiotics, especially carbapenems, thanks to its complicated mechanism by which it can acquire exogenous genes. The purpose of this research is to have a review of empirical studies surveying the resistance to beta-lactams in Iran in order to investigate the most reliable methods by which the incidence of infections can be decreased and controlled.

Nonlinear couplings and energy transfers in micro- and nano-mechanical resonators: intermodal coupling, internal resonance and synchronization.

Extensive development of micro/nano-electromechanical systems (MEMS/NEMS) has resulted in technologies that exhibit excellent performance over a wide range of applications in both applied (e.g. sensing, imaging, timing and signal processing) and fundamental sciences (e.
