This study aims to determine the levels of macro minerals such as potassium, calcium, sodium, and magnesium in fresh noni fruit. The sample fruit was destructed, then quantitative analysis were performed using atomic absorption spectrophotometry (AAS) at a wavelength 766.5 nm for potassium; 422.7 calcium; 589.0 sodium; 285.2 magnesium. advantages this method are selective sensitive. average % r...

We have previously presented evidence that electrical activity and increased cytosolic calcium reduce the density of sarcolemmal tetrodotoxin (TTX)-sensitive sodium channels in cultured rat muscle cells (Sherman, S. J., and W. A. Catterall (1984) Proc. Natl. Acad. Sci. U. S. A. 81: 262-266). We show here that growth of cells in ryanodine has a biphasic effect on sodium channel number. At low co...

1. Serum calcium and phosphate, calcium absorption and calcium excretion were measured in twenty-seven cases of chronic renal failure. 2. Hypocalcaemia was present in thirteen cases and tended to be more severe in patients with the most severe degree of renal failure. 3. The hypocalcaemia could not be attributed to hyperphosphataemia since many of the patients with hypocalcaemia had normal seru...

BACKGROUND Kidney stone disease is common in industrialized countries. Recently, it has attracted growing attention, because of its significant association with adverse renal outcomes, including end stage renal disease. Calcium-containing kidney stones are frequent with high recurrence rates. While hypercalciuria is a well-known risk factor, restricted intake of animal protein and sodium, combi...

OBJECTIVE The primary aim of this study was to compare the in vivo efficacy and safety of dentifrices containing either 5% NovaMin or 5% potassium nitrate, and a non-desensitizing dentifrice, on dentin hypersensitivity in a four-week, double-blind clinical study among a population in south India. In addition, a companion scanning electron microscopy evaluation was performed to demonstrate wheth...

PURPOSE In this study, the effect of calcium sodium phosphosilicate (NovaMin) desensitizing agent, which is a powder-based system, and hydroxyethyl methacrylate and glutaraldehyde (Gluma desensitizer), which is liquid-based system, on dentinal tubule occlusion was analyzed by scanning electron microscope. The effects of the above two along with one control group were compared to determine the m...

BACKGROUND White spot lesions and gingivitis represent common, yet challenging, dilemmas for orthodontists. Fluoride has shown some benefit as a protective measure against demineralization; however, this is usually insufficient for orthodontic patients with less than ideal oral hygiene. Dentifrices containing calcium sodium phosphosilicate bioactive glass (NovaMin) have been proposed to aid in ...

Isolated adult rat hearts perfused in an isovolumic mode were used to study the effects of sodium-potassium pump inhibition and sodium-calcium exchange alterations on the tissue content of adenosine triphosphate, phosphocreatine, inorganic phosphate, and intracellular pH, all measured by phosphorus-31 nuclear magnetic resonance spectroscopy. Rates of oxygen consumption, contractile function, an...

BACKGROUND Berberine hydrochloride is a conventional component in Chinese medicine, and is characterized by a diversity of pharmacological effects. However, due to its hydrophobic properties, along with poor stability and bioavailability, the application of berberine hydrochloride was hampered for a long time. In recent years, the pharmaceutical preparation of berberine hydrochloride has improv...

Nociceptive sensory neurons are unusual in expressing voltage-gated inward currents carried by sodium channels resistant to block by tetrodotoxin (TTX) as well as currents carried by conventional TTX-sensitive sodium channels and voltage-dependent calcium channels. To examine how currents carried by each of these helps to shape the action potential in small-diameter dorsal root ganglion cell bo...
