Background. The prevalence of type 2 diabetes is increasing. The disease is known to be an important risk factor for cognitive decline. Given the importance of diagnosing and controlling cognitive disorders such as memory impairment in diabetic patients and the difference of cognitive impairments in different populations, we decided to investigate the relationship between type 2 diabetes with memory and executive function . Methods. This case-control study was performed on 30 type 2 diabetic patients (case group) and 30 nondiabetic patients (control group) referred to Sheikh ol-Rayis Clinic in Tabriz during 1997. Demographic information questionnaires and Persian Cognitive Assessment Package (PCAP) were administered to all subjects in both groups. Results. pPatients with diabetes achieved lower scores in working memory tests and concentration tests compared to controls (healthy controls). There was no significant difference between the two groups regarding executive function (P

Abstract In this study, a modified mesoporous adsorbent (MSU-S) impregnated by aluminum was used to remove the aromatic sulfur compounds from n-decane as the model fuel. Physical and chemical properties of as-synthesized adsorbent were investigated by XRD (X-Ray Diffraction), SEM (Scanning Electron Microscopy), FTIR (Fourier Transform Infrared spectroscopy) and BET (Brunauer–Emmett–Teller) method. Adsorptive desulfurization of model fuel was studied through batch and continues processes under mild temperature and normal atmospheric pressure. The equilibrium adsorption was modeled by Langmuir, Temkin, and Freundlich and the kinetics of adsorption was studied through first, second and intraparticle diffusion models. It was figured out that Temkin and the pseudo-second-order model were best fitting the adsorption equilibrium and describing the kinetics, respectively.
