The entry tropism of HIV-1 Env proteins from virus isolated from the blood and genital tract of five men with compartmentalized lineages was determined. The Env proteins isolated from the genital tract of subject C018 were macrophage-tropic proteins, while the remaining cloned env genes encoded R5 T cell-tropic proteins. The detection of a macrophage-tropic lineage of HIV-1 within the male genital tract strongly suggests that evolution of macrophage-tropic viruses can occur in anatomically isolated sites outside the central nervous system.

Toxoplasma gondii Infection in the Male Reproductive System: A Systematic Review.

Acta Parasitol

January 2025

Reproduction Group, Department of Microbiology and Parasitology, School of Medicine, University of Antioquia- UdeA, Medellín, Antioquia, Colombia.

Purpose: Toxoplasmosis is a worldwide widespread parasitic infection; it affects about 30% of the global population, either through acute toxoplasmosis or its sequels. Even though the male reproductive system is not the primary target for Toxoplasma gondii (T. gondii), studies have inquired into the possibility of presenting repercussions in this system directly or indirectly due to toxoplasmosis.

Sestrin2 ameliorates age-related spontaneous benign prostatic hyperplasia via activation of AMPK/mTOR dependent autophagy.

Biogerontology

January 2025

Department of Veterinary Medicine, College of Veterinary Medicine, Chungnam National University, 220 Gung-Dong, Yusung-Gu, Daejeon, 34134, Republic of Korea.

Benign prostatic hyperplasia (BPH), characterized as a chronic disease with unregulated enlargement of prostatic gland, is commonly observed in elderly men leading to lower urinary tract dysfunction. Sestrin2 plays a role in the maintenance of cellular homeostasis and protects organisms from various stimuli. The exact role of Sestrin2 in the etiology of BPH, a common age-related disease, remains unknown.

The 5th Edition of the "WHO Classification of Tumours: Urinary and Male Genital Tumours" introduces several significant updates to the classification of testicular tumours. These updates include revised terminology for special germ cell tumour subtypes (neuroectodermal and neuroendocrine tumours) of the testis. Additionally, the signet-ring stromal tumour and myoid gonadal stromal tumour have been introduced as distinct entities within the sex-cord stromal tumours.

Comparison of Clinical Outcomes Between Two Types of Dipeptidyl Peptidase-4 Inhibitors in Posttransplant Diabetes Mellitus in Kidney Transplantation Recipients: A Nationwide Population-Based Cohort Study in Korea.

Electronic address:

Background: Dipeptidyl peptidase-4 inhibitors (DPP-4i) are antidiabetic drugs known for their minimal side effects and limited drug interaction witih immunosuppressants, making them suitable for patients with diabetes and kidney transplant recipients. However, there is limited real-world information regarding the use of DPP-4 inhibitors in patients with post transplant diabetes mellitus (PTDM).

Method: We performed a retrospective observational cohort study of 13,828 kidney transplant recipients form Janary 1, 2002, through December 21, 2018, using the Korean National Health Information Database.
