Schwannomas are benign tumors originating from Schwann cells, with seminal vesicle schwannomas being exceedingly rare. This report describes a 54-year-old man with an incidental discovery of a right-sided seminal vesicle mass during a routine ultrasound examination. Further imaging, including MRI and contrast-enhanced CT scans, revealed a well-defined, encapsulated mass with heterogeneous signal intensity suggestive of schwannoma. Histopathological examination confirmed schwannoma, marked by positive S-100 and NSE expression and a Ki67 index of 5%. The patient underwent successful laparoscopic resection without complications and remained asymptomatic for over a month. This case underscores the importance of integrating MRI and histopathological findings to accurately diagnose seminal vesicle schwannomas and guide appropriate surgical management, highlighting the need for increased clinician awareness of this rare tumor.

Background/objectives: Benign prostatic hyperplasia (BPH) is one of the most common chronic diseases affecting the urinary tract that occurs mainly in men over 40 years of age. Among the natural therapies, proanthocyanidins (PACs), which can treat a wide range of immune-mediated inflammatory diseases (IMIDs), have been shown to play an important role in the treatment of pathologies concerning prostate health. In this regard, the present study aimed to evaluate the different bioactivities of a grape seed extract (GSE), rich in polymeric PACs, and its version processed under alkaline conditions (ATGSE), characterized by a higher content of oligomeric PACs, in an animal model of BPH induced by subcutaneous injection of testosterone (1 mg/mouse).

Artificial insemination (AI), as an efficient assisted reproduction technology, can help the livestock industry to improve livestock and poultry breeds, optimize production performance and improve reproductive efficiency. AI technology has been widely used in pig production in China, but boar fertility affects the effectiveness of AI, and more and more studies have shown that there are significant differences in the fertility of boars with similar semen quality indicators. Therefore, this study aimed to identify biomarker molecules that indicate the level of boar fertility, which is important for improving the efficiency of AI.

Background: The profitability of the beef industry is directly influenced by the fertility rate and reproductive performance of both males and females, which can be improved through selective breeding. When performing genomic analyses, genetic markers located on the X chromosome have been commonly ignored despite the X chromosome being one of the largest chromosomes in the cattle genome. Therefore, the primary objectives of this study were to: (1) estimate variance components and genetic parameters for eighteen male and five female fertility and reproductive traits in Nellore cattle including X chromosome markers in the analyses; and (2) perform genome-wide association studies and functional genomic analyses to better understand the genetic background of male and female fertility and reproductive performance traits in Nellore cattle.

a new species of deep-sea digenean, parasitizing the gallbladder of the "Bigeye grenadier" ( Günther, 1878) in the deep waters of the southeastern Pacific Ocean is described on the basis of morphological and molecular (28S rRNA) data. The new species is distinguishable from Yamaguti, 1940, the only other member of the genus, by its subterminal oral sucker, the position of the ovary and testes, the larger anterior seminal vesicle compared to the posterior one, and its larger eggs. In addition, the new species is a parasite of a deep-sea fish, whereas is a parasite of shallow-water fish.
