calcium fluoride deposit during fluoride application. uptake and retention of fluoride by saliva depends generally on the concentration of calcium. in this study, the effect of calcium pre-rinse on salivary fluoride concentration after a 900 ppm fluoride mouthwash was investigated.this cross-over double-blind randomized clinical trial was conducted in a girls' dormitory in zahedan university of...

background: heavy exercise cause muscle damage associated with production of inflammatory agents. the purpose of present study was to determine the effect of acute and 14-day coenzyme q10 supplementation on inflammatory, blood lactate and muscle damage in male middle-distance runners.   methods : eighteen male middle-distance runners in a randomized and quasi experimental study were allocated i...

fibroblasts could be considered as connective tissue cells that are morphologically heterogeneous with diverse functions depending on their location and activity. these cells play critical role in health and disease such as cancer and wound by production of collagen, fibronectin, cytokines and growth factors. absence of insulin and other growth factors in serum deprivation condition and similar...

background hypotension during spinal anesthesia is common and can lead to severe injuries and even death. administration of crystalloid fluids is advised to prevent occurrence of hypotension; however its effectiveness is still the matter of arguments. objectives this study was designed to compare the effects of ringer`s lactate and hydroxyethyl starch 6% on hemodynamic parameters after spinal a...

purpose: to investigate the effects of sodium bicarbonate (nahco3) on exhaustive activity and physiological parameters of fatigue in conscripts. materials and methods: thirty conscripts did wingate test in two groups: sodium bicarbonate group (treatment) and placebo (control) group. in both groups, sodium bicarbonate (0.3 g/kg of body mass) or placebo was ingested 60 minutes before the training...

OBJECTIVES To determine whether lactate levels and base deficits in critically ill surgical intensive care unit (SICU) patients correlate and whether either measure is a significant indicator of mortality and morbidity. METHODS A review was made of 137 SICU patients who had serial lactate and blood gas measurements. Patients were stratified by absolute lactate and base deficit values as well ...

Nitrobacter hamburgensis X14 is a facultative lithoautotroph that conserves energy from the oxidation of nitrite (NO(-)2) and fixes carbon dioxide (CO(2)) as its sole source of carbon. The availability of the N. hamburgensis X14 genome sequence initiated a re-examination of its mixotrophic and organotrophic potential, as genes encoding three flavin-dependent oxidases were identified that may fu...

Minimally invasive techniques to access subcutaneous adipose tissue for glucose monitoring are successfully applied in type1 diabetic and critically ill patients. During critical illness, the addition of a lactate sensor might enhance prognosis and early intervention. Our objective was to evaluate SAT as a site for lactate measurement in critically ill patients. In 40 patients after major cardi...

BACKGROUND As abnormally high serum D-lactate levels may cause neurological impairment, we determined whether patients undergoing continuous ambulatory peritoneal dialysis (CAPD) with lactate-containing fluids have increased serum D-lactate concentrations. METHODS D- and L-lactate concentrations were determined in peritoneal dialysis fluids and in serum from control subjects (n = 10), haemodi...

Lactate detection plays a significant role in healthcare, food industries and is specially necessitated in conditions like hemorrhage, respiratory failure, hepatic disease, sepsis and tissue hypoxia. Conventional methods for lactate determination are not accurate and fast so this accelerated the need of sensitive biosensors for high-throughput screening of lactate in different samples. This rev...
