Low Temperature Emissive Cyclometalated Cobalt(III) Complexes.

A series of Co complexes [Co(ImP)][PF], with HImP = 1,1'-(1,3-phenylene)bis(3-methyl-1-imidazole-2-ylidene)) and R = Me, Et, Pr, Bu, is presented in this work. The influence of the strong donor ligand on the ground and excited-state photophysical properties was investigated in the context of different alkyl substituents at the imidazole nitrogen. X-ray diffraction revealed no significant alterations of the structures and all differences in the series emerge from the electronic structures.

Complete genome sequence of singleton phage Magritte.

Actinobacteriophage Magritte was isolated from soil in Columbia, TN using as a host. Magritte is a singleton with a siphovirus morphology and a large genome of 133,228 bp encoding 250 predicted genes, including 26 tRNA genes.

Lateral Extraarticular Tenodesis in Revision Anterior Cruciate Ligament Reconstruction: An Analysis of Clinical Outcomes and Failure Rates.

: Lateral extraarticular tenodesis (LET) has been advocated in revision anterior cruciate ligament reconstruction (ACLR) to improve knee stability and furthermore, decrease failure rates. The aim of this study was to compare clinical outcomes, knee laxity, and failure rates after revision ACLR with LET (ACLR + LET) versus without LET. It was hypothesized that ACLR + LET improves clinical outcomes and reduces the failure rate.

Good functional outcome but high rates of instability recurrence after posterior open-wedge glenoid osteotomy for the treatment of posterior shoulder instability with increased glenoid retroversion at mid-term follow-up.

Purpose: To evaluate clinical, functional and radiological mid-term outcomes following posterior open-wedge glenoid osteotomy (POWGO) for the treatment of posterior shoulder instability (PSI) associated with increased glenoid retroversion.

Methods: Patients who underwent POWGO for the treatment of symptomatic PSI with glenoid retroversion >10° and participated in a previous study assessing short-term outcomes were included after a minimum follow-up of 5 years. Clinical (Rowe score and physical examination) and functional outcomes (Oxford Shoulder Instability Score [OSIS] and visual analogue scale [VAS] for pain) were assessed.

[Conservative and joint-preserving therapy for knee osteoarthritis].

The treatment of knee osteoarthritis requires a multimodal approach and depends on the symptoms and stage of the disease. Conservative therapy is the first-line treatment and includes life-style changes (weight loss, exercise therapy), topical and oral pain medication, and intraarticular application of hyaluronic acid or platelet-rich plasma. Surgical joint-preserving therapies comprise knee arthroscopy to remove unstable meniscus tears or foreign bodies as well as osteotomy for unicompartmental arthrosis in case of leg malalignment.
