Sperm recovery and ICSI outcomes in non-obstructive azoospermia with cryptorchidism treated by orchiopexy: a systematic review and meta-analysis.

The aim of this meta-analysis was to quantify the available data concerning sperm retrieval rate (SRR) subsequent to testicular sperm extraction (TESE) and the clinical pregnancy rate (CPR) and live birth rate (LBR) subsequent to TESE and intracytoplasmic sperm injection (ICSI) in patients with non-obstructive azoospermia with cryptorchidism treated by orchidopexy. Furthermore, the aim was to explore the potential predictors of SRR, CPR and LBR within this population. Extensive searches were conducted in PubMed, Embase, Cochrane and Web of Science databases, and 23 articles were included in the study, with 1496 patients.

Quality evaluation of metabolic and bariatric surgical guidelines.

Objective: To evaluate the quality of surgical guidelines on bariatric/metabolic surgery.

Methods: Four independent reviewers used the AGREE II (The Appraisal of Guidelines for Research and Evaluation II) tool to assess the methodological quality of the included guidelines and conducted a comparative analysis of the main recommendations for surgical methods of these guidelines.

Results: Nine surgical guidelines were included in this study.

Implications of microglial heterogeneity in spinal cord injury progression and therapy.

Microglia are widely distributed in the central nervous system (CNS), where they aid in the maintenance of neuronal function and perform key auxiliary roles in phagocytosis, neural repair, immunological control, and nutrition delivery. Microglia in the undamaged spinal cord is in a stable state and serve as immune monitors. In the event of spinal cord injury (SCI), severe changes in the microenvironment and glial scar formation lead to axonal regeneration failure.

The Role of CD147 in Pathological Cardiac Hypertrophy Is Regulated by Glycosylation.

CD147, also known as EMMPRIN or basigin, is a transmembrane glycoprotein receptor that activates matrix metalloproteinases and promotes inflammation. CD147 function is regulated by posttranslational modifications of which glycosylation has attracted the most attention. In this study, we demonstrated that glycosylated CD147 was the dominant form in heart tissue, and its levels were markedly elevated in response to transverse aortic constriction (TAC).
