The purpose of this study was to determine the effects of concentric (Con) and eccentric (Ecc) muscle actions on leg muscle sympathetic nerve activity (MSNA). Two protocols were utilized. In protocol 1, eight subjects performed Con and Ecc arm curls for 2 min, with a resistance representing 50% of one-repetition maximum for Con curls. Heart rate (HR) and mean arterial pressure (MAP) were greate...

After decades of research, blindsight is still a mysterious and controversial topic in consciousness research. Currently, many researchers tend to think of it as an ideal phenomenon to investigate neural correlates of consciousness, whereas others believe that blindsight is in fact a kind of degraded vision rather than "truly blind". This article considers both perspectives and finds that both ...

Existing FPGAs have fairly simple and ine cient con guration mechanisms due to the relative infrequency of recon guration. However a large class of dynamically con gurable architectures for DSP and communications can bene t from special-purpose con guration mechanisms which allow signi cant savings in con guration speed, power and memory. Light weight con guration mechanisms allow much ner grai...

Concanavalin A (Con A), a tetravalent lectin, was shown to impair 8 chick embryo fibroblast (8 d CEF) spreading on a laminin (LM) substrate but not on a fibronectin substrate (FN), suggesting that cell surface Con A binding proteins could be involved in 8 d CEF spreading on a LM substrate. The interaction of Con A-binding proteins with Con A is dependent upon the carbohydrate moieties of the is...

This study was aimed to find a correlation between the extent of concanavalin A (Con A) binding to lymphocytes and the blastogenic effect of the lectin on these cells. 63Ni-labeled Con A was used in the lectin-binding experiments. Binding of Con A to a small fraction (approximately 3#{176}/o) of Con A binding sites in rat lymphocytes is required for the maximal stimulation of RNA synthesis. Bin...

Introduction: The production of Reaction Oxygen Species (ROS), lowers cellular antioxidant levels, and enhances oxidative stress in many tissues, especially the liver. Efficient liver function is extremely important to the overall health. The key to helping prevent long-term damage is to decrease oxidative stress. The purpose of this study was to assess the effects of treadmill training with vi...

Chemical derivatization of tetrameric concanavalin A (Con A) with succinic anhydride or acetic anhydride converts the protein to a dimeric molecule without altering its carbohydrate-binding specificity. At low concentrations, the dose-response curves for the mitogenic stimulation of mouse spleen cells by native Con A and succinyl-Con A are similar. Above lectin concentrations of 10 ug/ml, howev...

l artículo trata del diseño y construcción de una tarjeta de expansión para PC con ocho canales de entrada, con conversión de señales analógicas a señales digitales, basado en el Convertidor Analógico Digital ("Analogic Digital Converter", ADC) ADC 0809 de la empresa National Semiconductor, funcionando a una frecuencia de reloj de 640 KHz, y ventana de 0 a 5 voltios; cuatro canales de salida co...

ABSTRACT So‡ware Product Lines (SPLs) have many features for customization. Œis raises the challenge to €nd good performing con€gurations for an anticipated workload. As SPL con€guration spaces are huge, it is infeasible to benchmark all con€gurations to €nd an optimal one. Prior work focused on building performance models to predict and optimize SPL con€gurations; we randomly sample and recurs...

Optimistic replication is often viewed as essential for large scale systems and for supporting mobile computing. In optimistic replication, updates can be made concurrently to di erent le replicas, resulting in multiple versions of the le. To recover from these con icting updates, after-the fact con ict resolution actions are required to recombine multiple versions into one. This paper de nes t...
