Various physico-chemical parameters, including fluoride (F(-)), were analyzed to understand the hydro-geochemistry of an aquifer in a semi-arid region of India. Furthermore, the quality of the shallow and deep aquifer (using tube well and hand pumps) was also investigated for their best ecological use including drinking, domestic, agricultural and other activities. Different multivariate techni...

Possible appliance of effective and safe alkalizing agent in the treatment of metabolic acidosis could be of particular interest to humans experiencing an increase in plasma acidity, such as exercise-induced acidosis. In the present study we tested the hypothesis that the daily oral intake of 2L of hydrogen-rich water (HRW) for 14 days would increase arterial blood alkalinity at baseline and po...

A model is presented suggesting the interaction of CO(2) and bicarbonate on lipids of the cell membrane. The interfacial tensions between water and oil (benzene) phases were measured using the stalagmometer and the sessile drop methods. Effects of electrolyte solutions and of CO(2) on molecular arrangement at the interface were calculated. Chloride solutions against oleic acid in benzene produc...

A simple model of cystic fibrosis (CF) is proposed, based on the apical membrane (ApM) potential. The ApM of epithelial cells is highly permeable to sodium and activation of CFTRs makes it permeable to chloride. Calculated ApM potentials of cells with activated cystic fibrosis transmembrane conductance regulators (CFTRs) are between the sodium and chloride Nernst values and thus allow rapid abs...

Propylene glycol (PG) is used as a solvent in numerous medications, including trimethoprim/sulfamethoxazole (TMP/SMX) and lorazepam, and is metabolized in the liver to lactic acid. Cases of lactic acidosis related to PG toxicity have been described and always involved large doses of benzodiazepines and PG. We present the first case of severe lactic acidosis after a 3-day course of TMP/SMX alone...

The Fanconi Syndrome is a generalized proximal tubule defect leading to urinary wasting of many solutes such as glucose, amino-acids, phosphates and bicarbonates that results in polyuria, growth failure and resistant rickets(l,2). It is an. uncommon tubulopathy and is usually secondary to a systemic disease, metabolic disorder or drug toxicity. Of the 40 inherited tubulopathies seen at our neph...

Minute amounts of photosynthesis in marine plants can be accurately measured by adding a little phenolphthalein to the sea water, and observing changes in the color of the indicator. In the case of fresh water aquatics bicarbonates are added. By this method it is found that Ulva which has been kept in the dark begins photosynthesis as soon as it is exposed to sunlight and that the rate steadily...

In rabbits given cholecystokinin-pancreozymin intravenously a statistically significant increase in bile volume and alkaline phosphatase (AP) activity was observed. There was also an increase in the total amount of protein, cholesterol, bicarbonates Na, K, Ca, Mg, and the total activity of alkaline phosphatase and leucineaminopeptidase (LAP) secreted in bile within 90 minutes after pancreozymin...

Contamination types, levels and their behavior within drilling wastes is determined by the local geological conditions and drilling mud design; notably lubrication fluids, weighting agents and anti-foaming agents. Such additives can contain potentially toxic elements such as aluminum and barium. Besides being contaminated, drilling wastes often have a high pH due to the addition of lime, causti...
