Psychometric Tests and Spatial Navigation: Data From the Baltimore Longitudinal Study of Aging

Baltimore Longitudinal Study of Aging

Longitudinal examination of obesity and cognitive function: results from the Baltimore longitudinal study of aging.

BACKGROUND Obesity indices (i.e. BMI, waist-to-hip ratio) show differential relationships to other health outcomes, though their association to neurocognitive outcome is unclear. METHODS We examined whether central obesity would be more closely associated with cognitive function in 1,703 participants from the Baltimore Longitudinal Study of Aging. RESULTS Longitudinal mixed-effects regressi...

Circulating Brain-Derived Neurotrophic Factor and Indices of Metabolic and Cardiovascular Health: Data from the Baltimore Longitudinal Study of Aging

BACKGROUND Besides its well-established role in nerve cell survival and adaptive plasticity, brain-derived neurotrophic factor (BDNF) is also involved in energy homeostasis and cardiovascular regulation. Although BDNF is present in the systemic circulation, it is unknown whether plasma BDNF correlates with circulating markers of dysregulated metabolism and an adverse cardiovascular profile. M...

Cerebellum Parcellation and Data Analysis of the Baltimore Longitudinal Study

Description: The aim of this project is to run an existing cerebellum parcellation algorithm on a cohort of healthy aging controls. The project will establish normative estimates of volumes for various regions of the cerebellum during the aging process. The project is an opportunity to learn about the anatomy of core portion of the human brain while being engaged in a cutting edge research proj...

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
