Abstract With the availability of significant amount data, data-driven decision making becomes an alternative way for solving complex multiagent problems. Instead using domain knowledge to explicitly build models, approach learns decisions (probably optimal ones) from available data. This removes bottleneck in traditional knowledge-driven making, which requires a strong support experts. In this...

DIDS is a commonly used anion channel antagonist that is putatively cytoprotective against ischemic insult. However, recent reports indicate potentially deleterious secondary effects of DIDS. To assess the impact of DIDS on cellular viability comprehensively we examined neuronal morphology and function through 24 hours treatment with ACSF ± DIDS (40 or 400 µM). Control cells were unchanged, whe...

Background: Some respiratory diseases may induce alveolar hypoxia thereby hypoxic pulmonary vasoconstriction (HPV). However, the mechanisms of this physiologic phenomenon are not fully understood. This study was the first to investigate the role of anion exchanger in sustained HPV.Methods: Experiments were performed in the isolated perfused rabbit lung. After preparation, the lungs were divided...

Background: The mechanism of hypoxic pulmonary vasoconstriction (HPV) is still debatable. It has been proposed that reactive oxygen species (ROS) might be involved in HPV. However, there is no special transporter for superoxide anion in the cell membrane and it may release from the cells via anion exchanger. Therefore, the aim of this study was to investigate the interaction of ROS and anion ex...

The compound 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid (DIDS) is an efficient anion exchanger inhibitor that can block the activities of anion exchanger 2 (AE2), which plays an indispensable role in gastric acid secretion. DIDS also has potent anti-oxidative and antiapoptosis activities. This study aimed to investigate the effect of DIDS on ethanol-induced mucosal damage in rats and to e...

Net K and Cl effluxes induced by valinomycin or by gramicidin have been determined directly at varied external K, denoted by [K]o, in the presence and absence of the anion transport inhibitors DIDS (4,4'-diiso-thiocyano-2,2'-disulfonic acid stilbene), and its less potent analogue SITS (4-acetamido-4'-isothiocyanostilbene-2,2'-disulfonic acid). The results confirm that pretreatment with 10 micro...

DIDS (4,4'-di-isothiocyanostilbene-2,2'-disulfonate), an anion channel blocker, triggers Ca2+ release from skeletal muscle SR (sarcoplasmic reticulum). The present study characterized the effects of DIDS on rabbit skeletal single Ca2+-release channel/RyR1 (ryanodine receptor type 1) incorporated into a planar lipid bilayer. When junctional SR vesicles were used for channel incorporation (native...

Others have shown that H(2)DIDS reversibly and covalently binds to the first lysine (K) in the SKLIK motif at the extracellular end of transmembrane segment 5 of the Cl-HCO(3) exchanger AE1. Here we mutated K558, K559, and/or K562 in the homologous KKMIK motif of human NBCe1-A. We expressed constructs in Xenopus oocytes, and used a two-electrode voltage clamp to test the sensitivity of the NBC ...
