Abstract The expansion of agriculture in the southeast Amazon-Savanah transitional area has greatly decreased forest cover and influenced stream structure functioning. We assessed effects loss on integrity streams by assessing physical conditions taxonomic functional diversity fish assemblages this area. hypothesize that low cover, especially adjacent to streams, results poor (e.g., warmer temp...
Background & Objective: Wound dressing and healing in diabetic patients is encountered with many problems. This study aims to investigate the effect of bone marrow derived mesenchymal stem cells (BM-MSCs) on the survival of random skin flap (RSF) on Streptozotocin-induced diabetic rats (STZ) using an optical microscope. Materials & Methods: In this study, 60 male Albino Wistar rats were used...
introduction: previous studies have indicated a relationship between mptp pore and av nodal rate-dependent properties. the aim of present study was to determine acute direct effects of cyclosporine on extracellular field potential of isolated rabbit av node during experimental atrial fibrillation. methods: in one group of male new zealand rabbits (1.5-2.5 kg) cumulative concentrations of cyclos...
Transitional flow, whereby the motion of a fluid changes from laminar to turbulent flow, was successfully identified by Reynolds (1883) almost 130 years ago. According to ASHRAE (2009), for a round pipe, in general, laminar flow exists when the Reynolds number is less than 2 300. Fully turbulent flow exists when the Reynolds number is larger than 10 000 and transitional flow exists for Reynolds...
BACKGROUND Interleukin (IL)-13 induces goblet cell metaplasia and plays an important role in mucus hypersecretion in asthma. We previously reported that IL-13 induced goblet cell differentiation along with less ciliated cell differentiation in guinea pig tracheal epithelial cells in vitro. In this study, we asked whether elimination of IL-13 could reverse the established goblet cell metaplasia ...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
Structural analysis of the High Zagros Zone and southwestern rim of the Sanandaj-Sirjan Zone in the Chaharmahal-va-Bakhtyari area resulted in recognition of a thrust system comprises the Ben, Hafshejan, Farsan, Kuhrang and Bazoft thrust sheets from NE to SW. In this study, quartz and calcite microstructures as well as fluid inclusions have been utilized to inspect deformation conditions of the ...
BAFF is an important prosurvival cytokine for mature B cells. However, previous studies have shown that BAFFR is already expressed at the immature B cell stage, and that the prosurvival protein Bcl-2 does not completely complement the B cell defects resulting from the absence of BAFFR or BAFF. Thus, we hypothesized that BAFF also functions to aid the differentiation of nonautoreactive immature ...
the transition of a squared surface to a spherical one is one of the important issues of construction in the world architecture history. the combination can numerously be observed in the iran's architecture prior to the islamic period. for instance, the palace of shapur (a king) which was splendid and daring palace had a ceremonial court and featured a parabola dome. chahar taq (four arche...
In this study, we examined characteristics associated with experiencing persistent and transitional adult food insecurity and how persistent and transitional adult food insecurity influences toddler cognitive and motor development, along with toddler's weight and health status. Using the first 2 waves of the Early Childhood Longitudinal Study-Birth Cohort, 4 mutually exclusive variables capturi...
