Jejunal diverticulosis is a rare gastrointestinal condition manifested as benign outpouching from the jejunal wall. It is usually asymptomatic, but may present as obscure gastrointestinal bleeding. This condition is often found incidentally in the imaging work-up of patients with other gastrointestinal conditions. We present a case of jejunal diverticulosis in a 65-year-old gentleman with obscure overt gastrointestinal bleed.
Ureteral triplication is a rare congenital anomaly of the urinary tract. We report a case of ureteral triplication with contralateral partial kidney duplication in a patient with right loin pain. The development and types of ureteral triplication and the features of type 2 ureteral triplication on intravenous urography and magnetic resonance urography are described.
Working electrode (WE) fabrication offers significant challenges in terms of achieving high-efficiency dye-sensitized solar cells (DSCs). We have combined the beneficial effects of vertical nanorods grown on conducting glass substrate for charge transport and mesoporous particles for dye loading and have achieved a high photoconversion efficiency of (η) > 11% with an internal quantum efficiency of ∼93% in electrode films of thickness ∼7 ± 0.5 μm. Controlling the interface between the vertical nanorods and the mesoporous film is a crucial step in attaining high η. We identify three parameters, viz., large surface area of nanoparticles, increased light scattering of the nanorod-nanoparticle layer, and superior charge transport of nanorods, that simultaneously contribute to the improved photovoltaic performance of the WE developed.
