AI Article Synopsis
- - The study investigates the early development of the prostate in female gerbils, focusing on the formation of epithelial buds between embryonic days 20 and 24.
- - Epithelial buds in the female prostate form away from the paraurethral mesenchyme and connect with it by day 24, highlighting a unique budding pattern compared to males.
- - The research identifies the presence of steroid nuclear receptors in certain tissues, as well as specific cell types that change location during development, which are crucial for understanding the prostate's growth dynamics.
Article Abstract
The presence of the prostate in female mammals has long been known. However, pieces of information related to its development are still lacking. The aim of this study was to explore the budding dynamic during the initial prostate development in female gerbils. Pregnant females were timed, the fetuses were euthanized, and the urogenital sinus was dissected out between the embryonic days 20 and 24 (E20-E24 groups). Newborn pups (1-day-old; P1 group) underwent the same procedures. The female prostate development was based on epithelial buds which arose far from the paraurethral mesenchyme (PAM). The epithelial buds reached the PAM at prenatal day 24, crossing a small gap in the smooth muscle layer between the periurethral mesenchyme (PEM) and the PAM. Steroid nuclear receptors such as the androgen receptor and estrogen receptor alpha were localized in the PEM through the urethral wall, although some epithelial labeling was also present in the urogenital sinus epithelium (UGE). P63-positive cells were found only in the UGE, becoming restricted to the basal compartment after the 23rd prenatal day. The results showed that the gerbil female prostate exhibits a distinct budding pattern as compared to the male prostate development.

Bull fertility is a multi-factorial trait and is affected by many factors, such as nutrition, genetics, and epigenetics. Superior quality male germplasm with high genetic merit helps to improve the livestock production trait. To achieve the target of livestock production, the availability of superior male germplasm is a great concern.

Sulfamethoxazole/trimethoprim (SMX/TMP) is a commonly used antimicrobial agent for treating common bacterial infections such as urinary tract infection (UTI), combined with doxycycline for community-acquired methicillin-resistant (MRSA), and invaluable in pneumonia (PJP), previously classified as . Of its known adverse reactions, hepatotoxicity rarely comes to mind, but indeed, it is a recognized but very rare adverse reaction that may lead to liver failure in adults and even rarer in children. We present a case of hepatotoxicity in a 43-year-old male patient on no prior medication who developed jaundice and highly elevated liver enzymes one week after the administration of Bactrim for the treatment of UTI in association with prostatism, symptoms of decreased urinary force due to obstruction of flow through the prostate gland.

Objective: To evaluate the efficacy of a machine learning model for predicting prostate-specific antigen (PSA) persistence after radical prostatectomy (RP).
Methods: Data from 470 patients who underwent RP at the Affiliated Hospital of Qingdao University from January 2018 to June 2021 were retrospectively analyzed. Ten risk factors, including age, body mass index (BMI), preoperative PSA, biopsy Gleason score, total prostate specific antigen density (PSAD), clinical tumor stage, clinical lymph node status, seminal vesicle invasion, capsular invasion and positive surgical margin, were included in the analysis.

Background: Increasing evidence indicates that cancer stem cells (CSCs) and cancer stem-like cells form a special subpopulation of cells that are ubiquitous in tumors. These cells exhibit similar characteristics to those of normal stem cells in tissues; moreover, they are capable of self-renewal and differentiation, as well as high tumorigenicity and drug resistance. In prostate cancer (PCa), it is difficult to kill these cells using androgen signaling inhibitors and chemotherapy drugs.

Background: The global incidence of prostate cancer (PCa) is rising, necessitating improved diagnostic strategies. This study explores coagulation parameters' predictive value for clinically significant PCa (csPCa) and develops a nomogram.
Research Design And Methods: This study retrospectively analyzed data from 702 patients who underwent prostate biopsy at Shandong Provincial Hospital (SDPH) and 142 patients at Shandong Cancer Hospital and Institute (SDCHI).
