1. Evaluation of the remineralization capacity of CPP-ACP containing fluoride varnish by different quantitative methods
ABSTRACT Objective The aim of this study was to evaluate the efficacy of CPP-ACP containing fluoride varnish for remineralizing white spot lesions (WSLs) with four different quantitative methods. Material and Methods Four windows (3x3 mm) were created on the enamel surfaces of bovine incisor teeth. A control window was covered with nail varnish, and WSLs

2. Phosphorus available in acid and rectified soils with application of soluble, reactive and natural phosphate / Fósforo disponível em solos ácidos e corrigidos com aplicação de fosfatos solúvel, reativo e natural
Este trabalho avaliou o comportamento das fontes de fósforo: Arad, Fosforita Alvorada e Superfosfato Triplo em dois solos. - um arenoso e outro argiloso. -, na condição de acidez natural e, após a correção, atingir saturação por bases a 70%. O delineamento experimental utilizado foi inteiramente casualizado, com esquema fatorial (2x2x3x4), sendo: doi

3. Increased Efficiency of Hemodialysis with Citrate Dialysate: A Prospective Controlled Study
Background and objectives: A bicarbonate dialysate acidified with citrate (CD) has been reported to have local anticoagulant effect. This study examines the effect of CD on dialysis efficiency, measured as eKt/Vurea, and predialysis concentrations of BUN, creatinine, phosphate, and β-2 microglobulin in chronic dialysis units.

4. Ca2+-ATPase deficiency in a patient with an exertional muscle pain syndrome.
31P Magnetic resonance spectroscopy studies were carried out in vivo on skeletal muscle of a patient with verapamil-responsive, chronic, progressive post-exertional muscle pain. A sister suffered from a similar complaint. The results showed that the muscle: (1) decreased its high energy phosphate content more rapidly than normal during exercise, indicating e

5. Uncoupling by Acetic Acid Limits Growth of and Acetogenesis by Clostridium thermoaceticum
When cells of the anaerobic thermophile Clostridium thermoaceticum grow in batch culture and homoferment glucose to acetic acid, the pH of the medium decreases until growth and then acid production cease, at about pH 5. We postulated that the end product of fermentation limits growth by acting as an uncoupling agent. Thus, when the pH of the medium is low, t

6. Injury and recovery of Escherichia coli after sublethal acidification.
Over 99% of the viable cells of Escherichia coli K-12 were injured after a 60-min exposure to 0.3 M sodium acetate buffer at pH 4.2. Injured cells were those able to grow on Trypticase soy agar but unable to grow on violet red bile agar. The extent of both death and injury of acid-treated cells increased with decreasing pH or increasing concentration of acid

7. Parathyroid hormone decreases HCO3 reabsorption in the rat proximal tubule by stimulating phosphatidylinositol metabolism and inhibiting base exit.
The mechanism of inhibition of HCO3 transport by parathyroid hormone (PTH) in the proximal tubule is not clearly defined. Previous studies in vitro have suggested that this effect is mediated via cAMP generation, which acts to inhibit Na/H exchange, resulting in cell acidification. To examine this question in vivo, intracellular pH (pHi) was measured in the

8. Triamterene-β-cyclodextrin systems: Preparation, characterization and in vivo evaluation
The purpose of this research was to improve the solubility and therefore dissolution and bioavailability of triamterene, a poorly water soluble diuretic, by complexation with β-cyclodextrin. Triamterene has been reported to show low bioavailability after oral administration, with wide intersubject variation. This study presents the formulation of solid disp

9. Purification and characterization of Listeria monocytogenes phosphatidylinositol-specific phospholipase C.
We have purified to homogeneity the 33-kDa phosphatidylinositol-specific phospholipase C (PI-PLC) from the culture fluid of Listeria monocytogenes, a facultative intracellular pathogen. The protein was overexpressed, and secretion of PI-PLC was further enhanced by the addition of divalent cations to the culture medium. The basic protein (pI, approximately 9.

10. Effects of carbonic anhydrase inhibitors on contraction, intracellular pH and energy-rich phosphates of rat skeletal muscle.
1. The effects of carbonic anhydrase inhibitors on contractile parameters, intracellular pH (pHi) and energy-rich phosphates were studied in isolated rat soleus and extensor digitorum longus (EDL) muscles. 2. The muscles were incubated either in Ringer solutions (95% O2/5% CO2 = control) or in solutions to which one of the inhibitors, 5 X 10(-4) M-chlorzolam

11. Regulation of Vacuolar pH of Plant Cells: II. A 31P NMR Study of the Modifications of Vacuolar pH in Isolated Vacuoles Induced by Proton Pumping and Cation/H+ Exchanges
The vacuolar pH and the trans-tonoplast ΔpH modifications induced by the activity of the two proton pumps H+-ATPase and H+-PPase and by the proton exchanges catalyzed by the Na+/H+ and Ca2+/H+ antiports at the tonoplast of isolated intact vacuoles prepared from Catharanthus roseus cells enriched in inorganic phosphate (Y Mathieu et al 1988 Plant Physiol [in
