Anthropogenic CO2 presently at 400 ppm is expected to reach 550 ppm in 2050, an increment expected to affect plant growth and productivity. Paired stomatal guard cells (GCs) are the gate-way for water, CO2, and pathogen, while mesophyll cells (MCs) represent the bulk cell-type of green leaves mainly for photosynthesis. We used the two different cell types, i.e., GCs and MCs from canola (Brassic...

The purpose of this study was to determine how changes in [HCO3 ] alter the electrical properties of the retinal pigment epithelium (RPE). Experiments were conducted on the isolated chick retina-RPE-choroid preparation. The chamber holding the preparation allowed independent perfusion of the retinal and the choroidal surfaces. The light-evoked trans-tissue potential (TTP), the trans-epithelial ...

Introduction Acidosis is a frequent disorder among critically ill patients. When patient compensatory responses fail to restore a normal pH, administration of sodium bicarbonate (NaHCO3) or renal replacement therapy may be required. Intravenous NaHCO3 increases plasma Strong Ion Difference ([SID] = [Na] + [K] [Cl]) and HCO3 concentration by raising Na concentration. Although effective, this tre...

The impact of cell culture technology has been immense in the field research and pharmaceutical sciences. Suitable environmental conditions are paramount need order to maintain line an in-vitro condition. Since biological processes highly susceptible acid-base chemistry, variations among factors will have a severe effect on cellular integrity that often leads hypercapnia senescence cells. pH re...

Freshwater contamination remains a challenging issue for the sustainable management of wetland ecosystems. This study aims to evaluate water quality Jhilmila Lake, Kanchanpur, Nepal by adopting standard test procedures, geochemical indices, and multivariate statistical analysis. The surface samples were collected during postmonsoon season in 2018 assess hydrochemical parameters such as pH, elec...

HCO3 in pancreatic juice arises from the pancreatic duct cells. Secretin stimulates HCO3 secretion via a mechanism that involves activation of the adenylate cyclase pathway, activation of both basolateral K channels and the apical CFTR Cl channel, and stimulation of an apical Slc26mediated Cl/HCO3 exchanger (1). The Slc26 anion exchangers, Slc26a3 and Slc26a6, have both been localized to the ap...

THE hypothesis that saline administration results in dilutional acidosis was advanced by Shires and Holman in 1948. The antithesis, that physiologic defense mechanisms prevent reduction of bicarbonate concentration ([HCO3 ]) to the extent predicted by simple dilution, followed approximately 20 yr later and generally was accepted by 1975. In the 1990s, a variety of case reports and clinical stud...

Numerous geothermal resources of medium to low temperature have been reported in southern China. Suichuan County is one the regions where thermal manifestations are abundant. However, study regarding understanding water sources, hydrochemical composition and fluid-rock interaction lacks behind. Therefore, this has characterized slightly acidic alkaline bicarbonate waters medium-low area. Geothe...
