Blown spun fibers-based colorimetric sensor for detecting trace zinc in seminal fluid.

Rapid and accurate analysis of zinc in seminal fluid is an important tool for male infertility diagnosis and forensic investigation of sexual assault. Among the traditional techniques employed for this purpose, colorimetric solid-state sensors offer a simple and efficient alternative for screening this analyte. Herein, we evaluated the feasibility of using solution blow spinning as a fast, simple, and cost-effective method to develop porous membranes that can be manufactured as low-cost colorimetric solid-state sensing materials.

Right-sided ureteral hemangiosarcoma in a paraplegic dog.

Background: This study aims to describe a rare case of primary ureteral hemangiosarcoma, in which surgical intervention preserved the kidney and ureter after tumor removal.

Case Presentation: A 13-year-old, neutered male dog, weighing 14 kg, mixed-breed, presented with apathy, anorexia, acute-onset vomiting, and abdominal discomfort during the physical examination. Ultrasonography and pyelography revealed a right-sided dilation of the renal pelvis and ureter due to complete obstruction in the middle third of the ureter.

Fungal Diseases in Yerba Mate: Status and Management Strategies.

Yerba mate (Ilex paraguariensis St. Hil.), with its health benefits and socioeconomic significance, plays a crucial role in Argentina and other South American countries like Brazil and Paraguay.

A Case Study of a Rare Undifferentiated Spindle Cell Sarcoma of the Penis: Establishment and Characterization of Patient-Derived Models.

Rare sarcomas present significant treatment challenges compared to more prevalent soft tissue sarcomas due to limited treatment options and a poor understanding of their biology. This study investigates a unique case of penile sarcoma, providing a comprehensive morphological and molecular analysis. Through the creation of experimental patient-derived models-including patient-derived xenograft (PDX), 3D, and monolayer primary cultures-we successfully replicated crucial molecular traits observed in the patient's tumor, such as smooth muscle actin and CD99 expression, along with specific mutations in genes like and .
