Colonic bicarbonate (HCO3(-)) secretion is a well-established physiological process that is closely linked to overall fluid and electrolyte movement in the mammalian colon. These present studies show that extracellular calcium-sensing receptor (CaSR), a fundamental mechanism for sensing and regulating ionic and nutrient compositions of extracellular milieu in the small and large intestine, regu...

In the proximal convoluted tubule (PT), the HCO3- reabsorptive rate is higher in early (EPS) compared with late proximal segments (LPS). To examine the mechanism of this HCO3- reabsorption profile, intracellular pH (pHi) was measured along the superficial PT of the rat under free-flow and stationary microperfusion using the pH-sensitive fluorescence of 4-methylumbelliferone (4MU). With 4MU supe...

The hydrochemical characteristics and variation rules of water in karst areas are important for the basic research field. Because only a few researches focused on humid subtropical dolomite basins past, Shanmuhe Basin its subbasin Huangzhouhe Shibing Dolomite Karst World Natural Heritage Site China were selected as study area. A total 215 samples collected analyzed. It was found that type basin...

Bonanno, Joseph A., Yi Guan, Sergey Jelamskii, and Xiao Jun Kang. Apical and basolateral CO2-HCO3 2 permeability in cultured bovine corneal endothelial cells. Am. J. Physiol. 277 (Cell Physiol. 46): C545–C553, 1999.—Corneal endothelial function is dependent on HCO3 2 transport. However, the relative HCO3 2 permeabilities of the apical and basolateral membranes are unknown. Using changes in intr...

Tunceli’deki en büyük akaçlama alanlarına sahip olan K-G akışlı Munzur ve Pülümür Nehirleri Tunceli Merkez’de birleşerek güneye doğru tek nehir olarak devam eder. Güneydeki alanda Dinar Rabat gibi daha küçük alanları yer alır. Bu çalışmada sözü edilen içerisinde alan soğuk sıcak mineralli suların hidrojeokimyasal özellikleri araştırılmıştır. Mineralli yüzeye ulaşmasını kontrol eden önemli yapıs...

DK, DKA and HONC cases admitted to Hacettepe University Hospital in a fifteen year period (19801995) were analysed. Diagnosis of DKA was based on the fulfillment of each of the following criteria: Plasma glucose on admission >250 mg/dl, plasma HCO3 <15mEq/L, pH <7.3, ketonemia and an elevated anion gap. Patients with a plasma glucose level >250 mg/dl, blood pH in the normal range and with posit...

Frost is the coating or deposit of ice that may form in cold conditions, usually overnight. If the temperature drops far enough for the plant cells to freeze, non hardy plants will die. Therefore, a research was laid out to study the influence of an anti-frost solution on growth, flowers quality and biochemical parameters of ornamental plants. The anti-frost solution was applied as foliar spray...

Introduction: Liver is the most important organ of drugs and xenobiotics metabolism and any damage to the liver is associated with dysfunction of this organ. This study was carried out to find the possible additive effect of the co-administration of Cinnamomum zeylanicum (cinnamon) and Zingiber officinale (ginger) extracts on carbon tetrachloride (CCl4</s...

Two approaches are distinguished in modern ecological monitoring. The first one is physicochemical analysis of environmental objects with respect to maximum allowable concentrations (MACs) of chemical substances, which is performed by standards methods in accordance with state regulations. The second approach (biological monitoring) is based on the methodology of biotesting and bio indication. ...

In the rabbit small intestine, there are three functionally different brush-border membrane (BBM) anion/HCO3- exchangers: 1) Cl/HCO3- exchange on the BBM of villus cells responsible for coupled NaCl absorption; 2) Cl/HCO3- exchange on the BBM of crypt cells possibly involved in HCO3- secretion; and 3) short-chain fatty acid (SCFA)/HCO3- exchange on the BBM of villus cells, which facilitates SCF...
