برآورد مشخصه های ساختاری جنگل در سطوح بزرگ با استفاده از داده های ماهواره ای اهمیت فراوانی در مدیریت پایدار جنگل دارد. هدف از این تحقیق، مقایسه تصاویر ماهواره ای با قدرت تفکیک متفاوت مکانی متوسط (aster و tm) و بالا (quickbird) در برآورد برخی مشخصه-های کمی (حجم سرپا، رویه زمینی و تعداد درختان در هکتار) جنگل سری یک جنگل شصت کلاته گرگان است. تصحیح هندسی و رادیومتری تصاویر انجام شد. با استفاده از ر...

We propose to extend CART for bivariate marked point processes provide a segmentation of the space into homogeneous areas interaction between marks. While usual tree considers marginal distribution response variable at each node, proposed algorithm, SpatCART, takes account spatial location observations in splitting criterion. introduce dissimilarity index based on Ripley’s intertype K-function ...

INTRODUCTION The optimal management of infants born to HIV-positive mothers who are untreated or have detectable viral load prior to delivery remains controversial. Despite the increasing use of combination antiretroviral therapy (cART) for post-exposure prophylaxis (PEP) of neonates at high risk of HIV infection, there is little safety and pharmacokinetic data to support this approach. The obj...

BACKGROUND Combination antiretroviral therapy (cART), the standard of care for HIV-1 infection, is considered to be successful when plasma viremia remains below the detection limit of commercial assays. Yet, cART fails in a substantial proportion of patients after the apparent success. No laboratory markers are known that are predictive of cART outcome in initial responders during the period of...

BACKGROUND Rates of first antiretroviral therapy (cART) modifications are high in most observational studies. The age-related differences in treatment duration and characteristics of first cART modifications remain underinvestigated. With increasing proportion of older patients in HIV population it is important to better understand age-related treatment effects. METHODS Patients were included...

The aim of this study was to investigate the involvement of dopaminergic receptors (DR) in behavioral sensitization, as measured by locomotor activity, and the over-expression of cocaine- and amphetamine-regulated transcript (CART) peptides after repeated administration of cocaine in mice. Repeated administrations of cocaine induced behavioral sensitization and CART over-expression in mice. The...

Cocaine- and amphetamine-regulated transcript (CART) peptides are neuropeptides that are expressed in brain regions associated with reward, such as the nucleus accumbens (NAc), and play a role in cocaine reward. Injection of CART into the NAc can inhibit the behavioral effects of cocaine, and injecting CART into the ventral tegmental area (VTA) reduces cocaine-seeking behavior. However, the exa...
