Assessing the aneurysm occlusion efficacy of a shear-thinning biomaterial in a 3D-printed model.

Metallic coil embolization is a common method for the endovascular treatment of visceral artery aneurysms (VAA) and visceral artery pseudoaneurysms (VAPA); however, this treatment is suboptimal due to the high cost of coils, incomplete volume occlusion, poor reendothelialization, aneurysm puncture, and coil migration. Several alternative treatment strategies are available, including stent flow diverters, glue embolics, gelfoam slurries, and vascular mesh plugs-each of which have their own disadvantages. Here, we investigated the in vitro capability of a shear-thinning biomaterial (STB), a nanocomposite hydrogel composed of gelatin and silicate nanoplatelets, for the minimally-invasive occlusion of simple necked aneurysm models.

Role of silver nanoparticles in fluorimetric determination of urea in urine samples.

Herein, an economical, analytical and sensitive method was established for the fluorometric determination of urea using freshly prepared silver nanoparticles (Ag-NPs) in real urine samples. The standard addition and second-order derivative methods were selected for the ongoing research work to eliminate the possible effect of interferences in a real environment. In this work, Ag-NPs were prepared by reducing silver nitrate salt in the presence of 1,3-di-(1H-imidazole-1-yl) -2-propanol (DIPO) in an aqueous medium.

Potential negative impact of informing patients about medication side effects: a systematic review.

Background Pharmacovigilance, as it is carried out primarily by healthcare professionals is more focused on being very objective in nature. Acknowledging the importance of the subjective experience of patients in pharmacovigilance was underpinned by its unique ability to bring about a more holistic understanding through the deep information unraveled by the patients. Medication safety-related information has to be shared with patients to allow them to be actively involved in their therapy and pharmacovigilance.
