A case-report of chromophobe renal cell carcinoma with renal subcapsular hematoma.

Introduction And Importance: Chromophobe renal cell carcinoma (CHRCC) is a rare subtype of renal cancer, accompanied by subcapsular renal hematoma (SRH) without a history of traumatic or hemorrhagic disease, which is clinically rare. The reason for CHRCC with SRH may be caused by tumor rupture or vascular rupture. In the early stage, it is often asymptomatic and can be easily overlooked and misdiagnosed, leading to delayed treatment and serious consequences.

Heterogeneous photocatalytic degradation kinetic of gaseous ammonia over nano-TiO2 supported on latex paint film.

Objective: To investigate the photocatalytic degradation of gaseous ammonia in static state by using nano-TiO2 as photocatalyst supported on latex paint film under UV-irradiation.

Methods: Experiments were conducted to study the relationship between the initial concentration of ammonia and the degradation products competing to be adsorbed on catalyst surface. Degradation of ammonia and its products were detected by spectrophotometry and catalytic kinetic spectrophotometry, respectively.
