Advances in desulfurization research of liquid fuel

Abstract: The new requirements for sulfur content in liquid fuels demand the use of novel deep desulfurization processes. 4-methyldibenzothiophene, 4,6dimethyldibenzothiophene and their alkyl-substituted derivatives are the key substances that need to be separated from diesel fuel and fuel oil. These compounds require higher hydrogen cons umption in the hydrodesulfurization process and the use of additional infrastructure in the treatment facility. The common hydrogenation catalysts are not very effective for the hydrogenization of these compounds, and new innovation for catalysts is required. The desulfurization of fuel oil obtained from oil shale is also becoming important and has different technological needs than other fuels. This paper critically discusses the non-hydrodesulfurization processes for liquid fuels, such as extraction, oxidation, and adsorption. These processes, their development, and recent advances in this research field are briefly evaluated as possible deep desulfurization methods.

Management of erectile dysfunction in hypertension: Tips and tricks

Abstract: Arterial hypertension is a major risk factor for cardiovascular disease and affects approximately one third of the adult population worldwide. The vascular origin of erectile dysfunction is now widely accepted in the vast majority of cases. Erectile dysfunction is frequently encountered in patients with arterial hypertension and greatly affects their quality of life of hypertensive patients and their sexual partners. Therefore, the management of erectile dysfunction in hypertensive patients is of paramount importance. Unfortunately, erectile dysfunction remains under-reported, under-recognized, and under-treated in hypertensive patients, mainly due to the lack of familiarity with this clinical entity by treating physicians. This review aims to discuss the more frequent problems in the management of hypertensive patients with erectile dysfunction and propose ways to overcome these problems in everyday clinical practice.
