Changes in intracellular chloride concentration, mediated by chloride influx through GABA(A) receptor-gated channels, may modulate GABA(B) receptor-mediated inhibitory postsynaptic potentials (GABA(B) IPSPs) via unknown mechanisms. Recording from CA3 pyramidal cells in hippocampal slices, we investigated the impact of chloride influx during GABA(A) receptor-mediated IPSPs (GABA(A) IPSPs) on the...

We have previously demonstrated that amiloride (amil) addition to the isolated ventral pelvic (VPel) skin of Bufo arenarum toad induces negative short-circuit current values, which are equivalent to the isotopically measured net chloride transport. In the present work, we found that exposure of various regions of toad skin to amil yielded different values of short-circuit current (aSCC): negati...

This paper reports the results for the pH of three buffer solutions free of chloride ion. The remaining six buffer solutions have saline media of the ionic strength I = 0.16 mol·kg, matching closely to that of the physiological sample. Conventional paH values for the three buffer solutions without the chloride ion and six buffer solutions with the chloride ion at I = 0.16 mol·kg from 5 ̊C to 55 ̊...

the aim of this study was to investigate the comparison between some seminal plasma parameters and age of the bull. concentrations of various biochemical parameters like fructose, glucose, total proteins, albumin and inorganic ions including na, k and cl ions of seminal plasma of breeding sahiwal bulls of different ageswere assessed. methods: 40sahiwal bullsdivided into 4 age groups.semen (2ml ...

Chloride channels play an essential role in a variety of physiological functions and in human diseases. Historically, the field of chloride channels has long been neglected owing to the lack of powerful selective pharmacological agents that are needed to overcome the technical challenge of characterizing the molecular identities of these channels. Recently, members of the LRRC8 family have been...

the analysis of the 27al and 35cl quadrupole coupling parameters of aluminum methyl chloride dimers were carried out on the basis of the density functional theory (dft). the available experimental values of quarupole coupling constants were compared with their calculated ones. in this investigation, the correlations were made between calculated 27al and 35cl nuclear quadrupole coupling constant...

In this paper, the single machine replacement problem is being modeled into the frameworks of stochastic dynamic programming and control threshold policy, where some properties of the optimal values of the control thresholds are derived. Using these properties and by minimizing a cost function, the optimal values of two control thresholds for the time between productions of two successive nonco...

with a mean precipitation rate, much lower than that of the world, iran is among the countries that face severe water challenges. the present study has dealt with the evaluation of hydrochemistry of faryab spring water in hormozgan province, iran. four different composite water samples have been analyzed to detect major anions, cations, total dissolved solids, electrical conductivity, ph, and s...

This study was designed to assess the validity of Conconi’s method, by means of heart rate and lactate threshold measurements to predict anaerobic threshold. The results presented in this paper, clearly demonstrate significant difference between anaerobic threshold values obtained by means of Conconi’s test (Conconi’s threshold) and anaerobic threshold values obtained by direct lactate blood co...
