The effect of the C-terminal octapeptide of cholecystokinin-pancreozymin (CCK-PZ), caerulein, and the C-terminal tetrapeptide of gastrin on pancreatic secretion of fluid, electrolyte, amylase, and protein was studied in anaesthetized dogs prepared with pancreatic fistulae. Against background stimulation of fluid secretion with submaximal doses of secretin, all the polypeptides produced a qualit...

Needle-like o r b ranch-like a ragonite was prepared from sparingly dissoluble magnesium carbonate and calcium chloride aqueous solution. The morphology, particle size, and aspect ratio of the product were characterized with SEM. The polymorphs and crystal size were characterized with XRD. Comparing with calcium sulfate and sodium carbonate that were used in our previous study, a high reactant ...

This study was carried out on the effectiveness of calcium chloride (CaCl2) treatments on the post harvest quality of peach fruits during cold storage at 10oC and 75 ± 5% RH. Different solutions of CaCl2 such as 1% (T1), 2% (T2) and 3% (T3) were prepared and the fruits were dipped for five minutes, while (To) was left with out calcium chloride treatment as control. The fruits were packed in cor...

Our objective was to test the hypothesis that changes in crossbridge phosphorylation in the swine carotid media are due to changes in the myoplasmic calcium concentration. The photoprotein aequorin was loaded intracellularly by incubation in a series of calcium-free solutions. This loading procedure did not affect subsequent stress development, myosin light chain phosphorylation, or ultrastruct...

We have previously demonstrated the presence of a cyclic GMP (cGMP)-dependent calcium-activated inward current in vascular smooth-muscle cells, and suggested this to be of importance in synchronizing smooth-muscle contraction. Here we demonstrate the characteristics of this current. Using conventional patch-clamp technique, whole-cell currents were evoked in freshly isolated smooth-muscle cells...

PURPOSE In the vertebrate retina, calcium-activated chloride channels are expressed in photoreceptor synaptic terminals. These channels are involved in the control of transmitter release in the dark. The search for their molecular identity has recently lead to the localization of the protein anoctamin 2 (also TMEM16B) in the outer plexiform layer of the rodent retina. Since both rod and cone ph...

Background/ Objectives: Chemical Oxygen Demand (COD) is a widely used aggregate organic pollutant index in national discharge standards and one of the critical parameters for water quality assessment. The conventional COD determination by wet oxidative method encounters problem chloride interference samples with high content. dichromate reflux oxidizes 85-95% matter also 100% ions samples, with...

The effect of Tamm-Horsfall protein isolated from urine of healthy subjects on calcium oxalate precipitation was studied in model systems of precipitation. The study was performed using following conditions: concentrations of calcium chloride 10 mmol/l, sodium chloride 150 mmol/l, oxalic acid 300 mumol/l; pH 6.0, and temperature 310 K. The concentration of Tamm-Horsfall protein varied between 1...

Bestrophins are a novel family of proteins that encode calcium-activated chloride channels. In this study we establish that Bestrophin transcripts are expressed in the mouse and human heart. Native mBest3 protein expression and localization in heart was demonstrated by using a specific polyclonal mBest3 antibody. Immunostaining of isolated cardiac myocytes indicates that mBest3 is present at th...
