Retroperitoneal laparoscopic partial nephrectomy for unilateral synchronous multifocal renal carcinoma with different pathological types: A case report.

Background: The majority of renal cell carcinomas are single lesions; unilateral synchronous multifocal renal carcinoma (USMRC) is rarely reported and poses a treatment challenge for urological oncologists.

Case Summary: A 56-year-old man was hospitalized for pain and discomfort in the right kidney area for 6 d. Contrast-enhanced computed tomography demonstrated cT1a renal tumors at the lower pole of the right kidney and a cT1b renal tumor at the middle dorsal portion of the right kidney.

Preparation of aluminum sludge composite gel spheres and adsorption of U(IV) from aqueous solution.

A novel three-dimensional aluminum sludge/polyvinyl alcohol/sodium alginate(AS/PA/SA) gel spheres were designed and prepared for uranium(VI) adsorption, and it overcomes the shortcomings of poor recycling of powdery aluminum sludge adsorbent and poor stability of sodium alginate. Experiments show that the P-S-AS has a good pH range for removal of uranium (4-5). Fitting experimental data with pseudo-first-order kinetic model and pseudo-second-order kinetic model shows that the adsorption of U(VI) by P-S-AS is a chemical action.

Proteomic analysis and comparison of intra‑ and extracranial cerebral atherosclerosis responses to hyperlipidemia in rabbits.

The present study aimed to investigate protein expression levels of intra‑ and extracranial atherosclerosis in rabbits following administration of a high‑fat diet. Rabbits were randomly divided into control (group A; n=9) and high‑fat diet (group B; n=9) groups. At week 12, tissues were sectioned from the common carotid artery (CCA) and middle cerebral artery (MCA).

Etiology and Management of Male Iatrogenic Urethral Stricture: Retrospective Analysis of 172 Cases in a Single Medical Center.

Purpose: To investigate the etiology and management of male iatrogenic urethral stricture in China.

Methods: The data of 172 patients with iatrogenic urethral stricture who underwent treatment at a high volume reference center in China from January 2008 to February 2014 were analyzed retrospectively. Databases were analyzed to understand the impact of different types of iatrogenic injury on stricture location, length and treatment of urethral strictures, as well as success rates.

Silencing the expression of Cbl-b enhances the immune activation of T lymphocytes against RM-1 prostate cancer cells in vitro.

Background: The ubiquitin ligase Cbl-b potently modulates T lymphocyte immune responses and is critical in modulating tumor-induced immunosuppression. The influence of Cbl-b in modulating T lymphocyte activity against prostate cancer remains ill defined. We have determined the effects of silencing Cbl-b expression in T lymphocytes and their subsequent cytotoxic activity against prostate cancer cells.
