Zinner syndrome unveiled: Ectopic ureter and seminal vesicle cyst leading to urinary dysfunction: A case report.

Zinner syndrome (ZS) is a rare congenital urological condition characterized by a triad of ipsilateral seminal vesicle cysts, unilateral renal agenesis, and ejaculatory duct obstruction, first described in 1914. This case report details the presentation and management of a 27-year-old male diagnosed with ZS following a 2-month history of urinary frequency, hesitancy, dysuria, and painful ejaculation. Physical examination revealed a left lower abdominal mass, and imaging confirmed the classic findings of ZS, including unilateral renal agenesis, an enlarged seminal vesicle cyst, and an ectopic ureter.

Leishmania donovani Modulates Macrophage Lipidome During Infection.

Obligate intracellular protozoan parasite, Leishmania donovani, causative agent of visceral leishmaniasis, led to impaired macrophage functions.

Evaluation of healing progression at surgical incision sites and the use of antiseptics for enhancing post-operative survival in subyearling Chinook salmon (Oncorhynchus tshawytscha).

In an attempt to develop more effective surgical implantation methods for fish, surgical incisions typical of those made for implanting micro-acoustic transmitters into the peritoneal cavity were evaluated on a weekly basis for healing progression using a suite of metrics. Additionally, four chemicals were evaluated at concentrations commonly used in aquaculture for their ability to prevent surgical site infection and thus to promote incision healing and survival. Chemical treatments included hydrogen peroxide (25, 50, and 100 mg l-1), salt (10 and 30 ppt), Argentyne (1:1, Argentyne:water), and PolyAqua (1/2 tsp 36 l-1).
