In order to study the prevalence of psoriatic arthritis in Imam Reza Hospital and determine the effects of factors like age, sex, familial history, type of skin involvement, nail involvement and duration of disease on psoriatic arthritis, 300 psoriatic patients over a period of 4 years were admitted and examined in the Department of Dermatology and Rheumatology in Imam Reza Teaching Hospita...

Background and Objective: Alzheimer’s disease (AD) is a multifactorial disease with debilitating consequences and few therapeutic strategies exist for it. With regard to antioxidant capacity and anti-β-amyloid polymerization potential of ellagic acid, this study was conducted to evaluate the effect of this substance on enhanced acetylcholinesterase reactivity in an experimental model of Alzheim...

INTRODUCTION  The accumulation of neurofibrillary tangles, composed of aggregated hyperphosphorylated tau protein, starts spreading early in specific regions in the course of Alzheimer's disease (AD), correlating with the progression of memory dysfunction. The non-invasive imaging of tau could therefore facilitate the early diagnosis of AD, differentiate it from other dementing disorders and al...

Microalga Chlorella protothecoides materials were assessed as substrates for anaerobic digestion (AD) aiming at the simultaneous production of biogas/methane and pigments: whole autotrophic (AA) heterotrophic algae (H); extracted microalgae from lipid (HExt); pretreated through enzymatic (HPEnz), autoclave (HPA), ultrasound (HPU) processes. AA was more suitable AD than H, it efficiently convert...

Accelerated forgetting has been proposed as the first sign in preclinical and early Alzheimer's disease (AD). The authors investigated learning and retention in participants who later developed AD with free and cued selective reminding (FCSR; H. Buschke, 1984; E. Grober & H. Buschke, 1987), a test that maximizes learning by inducing deep semantic processing and by controlling study and test con...

The chromatographic resolution of pregabalin enantiomers has been often achieved by derivatization of the molecule, in order to reach enough sensitivity at low concentrations of the minor enantiomer present in the active principle. In the present article, the development and optimization of two liquid chromatographic methods are presented for the direct resolution of pregabalin enantiomers on a...

For an integer d?2, a family F of sets is d-wise intersecting if for any distinct A1,A2,…,Ad?F, A1?A2?…?Ad??, and non-trivial ?A?FA=?. Hilton Milner conjectured that k?d?2 large enough n, the extremal (i.e. largest) k-element subsets [n] is, up to isomorphism, one following two families:A(k,d)={A?([n]k):|A?[d+1]|?d}H(k,d)={A?([n]k):[d?1]?A,A?[d,k+1]??}?{[k+1]?{i}:i?[d?1]}. The celebrated Hilton...
