this research was conducted in sefid-rud river of southern caspian sea and amounts of ionic (sodium, potassium, magnesium and calcium) and metabolic (cholesterol, total protein and glucose) parameters in 35 maturated and 45 immature female kutum blood determined. fish samples were collected monthly from march to may in 2008. blood samples were taken from the caudal vessels. no abnormalities or ...

NMDA receptor dependent long-term potentiation (LTP) and long-term depression (LTD) are two prominent forms of synaptic plasticity, both of which are triggered by post-synaptic calcium elevation. To understand how calcium selectively stimulates two opposing processes, we developed a detailed computational model and performed simulations with different calcium input frequencies, amplitudes, and ...

background: edible films and coatings have potential benefits for food packaging, particularly meat products. these coatings prevent weight loss and texture changes during shelf life by reducing moisture loss in fresh and frozen meat products. in this study, effect of calcium alginate edible coating on microbial and chemical properties of refrigerated lamb meat over a period of  5 days was inve...

introduction this study was intended to evaluate the nutritional value, phenolic compounds and digestibility coefficients of barberry leaves. berberis vulgaris is one of the major crops in the province. the province has more than 70 percent and 95 percent of the total area under cultivation of barberry. waste and foliage of barberry harvest traditionally used to feed livestock tannin concentrat...

INTRODUCTION Because foods fortified with calcium are increasingly available, the calcium content of calcium-fortified foods may not be adequately captured in traditional assessments of dietary intake, such as dietary records analyzed with commercially available software. The primary objective of our study was to design and test a calcium-focused food frequency questionnaire (CFFFQ) including f...

In the absence of definite experimental evidence, it has generally been assumed that the symptoms of tetany associated with increases in serum pH are due to a decrease in the concentration of ionic calcium. However, by means of the frog heart method, McLean and Hastings (1) were unable to demonstrate any significant change in calcium ions with change in pH. Because of the relatively narrow pH r...

The divalent cation chelator 1,2-bis(o-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid (BAPTA), often used to buffer physiological changes in cytosolic Ca(2+), also binds Zn(2+) with high affinity. In a recently published method (Lamboley et al. 2015. J. Gen. Physiol. http://dx.doi.org/10.1085/jgp.201411250), the absorbance shift of BAPTA at 292 nm was successfully used to determine the total ca...

Multiple linear regression analysis showed that total calcium was significantly and positively related to albumin, globulin, anion gap, and bicarbonate in plasma from 556 normal postmenopausal women. The residual constant of 1.21 mmol/L approximated the normal mean for ionized calcium in plasma. The coefficients derived from the multiple regression analysis were used to calculate ionized calciu...

A small quantity of extracellular calcium is required for the stimulation of lymphocytes by mitogens such as plant lectins. Lectin binding to the lymphocyte surface and early postbinding events that eventually lead to DNA synthesis are calcium dependent. Mitogenic lectins such as PHA and Con-A rapidly increase the size of an exchangeable pool of cell calcium and cause a smaller rise in intracel...

The objectives of this research were to assess the bioavailability of calcium using equilibrium dialysis after simulated gastric digestion method in 20 commonly consumed green leafy vegetables (GLVs) from the typical Indian diet, provide data on the content of calcium absorption inhibitors, like oxalate, phytate, tannin and dietary fibres, and evaluate the inhibitory effect of these compounds o...
