Depressive and Anxiety Disorders Increase Risk for Recurrent Anterior Shoulder Pain Following Arthroscopic Suprapectoral Biceps Tenodesis.

Purpose: To evaluate factors associated with postoperative anterior shoulder pain following arthroscopic suprapectoral biceps tenodesis (ABT) and to determine the clinical impact of postoperative anterior shoulder pain.

Methods: A retrospective study of patients that underwent ABT between 2016 and 2020 was conducted. Groups were categorized by the presence (ASP+) or absence (ASP-) of postoperative anterior shoulder pain.

Role of Canonical Wnt/β-Catenin Pathway in Regulating Chondrocytic Hypertrophy in Mesenchymal Stem Cell-Based Cartilage Tissue Engineering.

In the past 3 decades, the cartilage repair potential of mesenchymal stromal cells, or mesenchymal stem cells (MSCs), has been widely examined in animal studies. Unfortunately, the phenotype and physical properties of MSC-derived cartilage tissue are not comparable to native hyaline cartilage. In particular, chondrocytic hypertrophy, a phenotype that is not observed in healthy hyaline cartilage, is concomitant with MSC chondrogenesis.

[The role of histamine in regulation of spontaneous electrical activity of the rat ureter and bordering to bladder area].

The nature of the influence of histamine on the slow wave and spike spontaneous activity of both perirenal and peribladder bordering areas of the bladder zone has been studied. It is shown that under these conditions of activated renal section of the organ, in the distal part, the decrease in frequency of the slow waves occurred. The histamine effect also contributes to improvement of the conduction of the excitation wave propagating to the bladder, which destroys the coordination of spike activity of the latter with slow waves of ureteral bordering zone.

[Effect of nifedipine on electrophysiological properties of rat ureter spontaneous activity].

The work studied effect of various concentrations of nifedipine on the slow and fast spontaneous activities evoked in the perivesical and perirenal areas of the rat ureter. Whereas in the proximal zone of the organ at the low dose of nifedipine (0.06 and 0.
