Plasma amyloid β 42/40 ratios as biomarkers for amyloid β cerebral deposition in cognitively normal individuals
INTRODUCTION Plasma amyloid β (Aβ) peptides have been previously studied as candidate biomarkers to increase recruitment efficiency in secondary prevention clinical trials for Alzheimer's disease. METHODS Free and total Aβ42/40 plasma ratios (FP42/40 and TP42/40, respectively) were determined using ABtest assays in cognitively normal subjects from the Australian Imaging, Biomarker and Lifesty...

تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...
15 صفحه اولEffect of Continuous and Interval Training on Amyloid β 42 (Aβ42) and Malondialdehyde (MDA) Levels in Hippocampus of Elderly Rats
Introduction: Amyloid plaques in the brain increase with age. Thus, the present study aimed to evaluate the effect of continuous and interval training on Amyloid β 42 (Aβ42) and Malondialdehyde (MDA) levels in hippocampus of elderly rats. Methods: The present study was experimental one with two experimental groups and one control group. Thirty old male Wistar rats (18 weeks-old) divided into 3...
متن کاملAmide solvent protection analysis demonstrates that amyloid-β(1–40) and amyloid-β(1–42) form different fibrillar structures under identical conditions
AD (Alzheimer’s disease) is a neurodegenerative disorder characterized by self-assembly and amyloid formation of the 39–43 residue long Aβ (amyloid-β)-peptide. The most abundant species, Aβ(1–40) and Aβ(1–42), are both present within senile plaques, but Aβ(1–42) peptides are considerably more prone to selfaggregation and are also essential for the development of AD. To understand the molecular ...
متن کاملThe effect of cognitive-motor dual-task training on cognitive function and plasma amyloid β peptide 42/40 ratio in healthy elderly persons: a randomized controlled trial
BACKGROUND Physical activity reduces the incidence and progression of cognitive impairment. Cognitive-motor dual-task training, which requires dividing attention between cognitive tasks and exercise, may improve various cognitive domains; therefore, we examined the effect of dual-task training on the executive functions and on plasma amyloid β peptide (Aβ) 42/40 ratio, a potent biomarker of Alz...
