BACKGROUND Hyperglycemia is common in critically ill and surgical patients, as are core temperature disturbances. The effect of hyperglycemia on thermoregulatory defenses remains unknown. We determined the effect of blood glucose concentration on the shivering threshold in rabbits. METHODS Twenty-seven rabbits lightly anesthetized with isoflurane were randomly assigned to infusions of (1) sal...

Hyperalgesia is a common clinical phenomenon among opioid dependent patients on methadone maintenance therapy (MMT) and it may be associated with undertreated pain and/or therapeutic failure. This study aimed to investigate association between serum methadone concentration (SMC) and cold pressor pain responses. Cold pressor pain responses in 147 opioid dependent patients on MMT were assessed us...

Impact ionization in fully depleted (FD) Silicon On Insulator (SOI) n-Channel MOSFET is investigated as a function of the doping concentration. We have found that impact ionization increases with the decrease in the doping concentration and vice versa. Simulation results obtained from Sentaurus TCAD with the higher doping concentration can control the threshold voltage (Vth). Furthermore we hav...

abstract in the present research the effect of different concentrations of cr3+ on growth and uptake of chromium by mycelium of agaricus bisporus was investigated. chromium playes an important role in improvment of insulin action in diabetic patients. the aim of this research was to investingate tolerance threshold of the fungus to cr3+ concentrations. mycelium of a. bisporus was cultured in so...

concentrations of elements (as, co, cu, ni, mo, pb, v, cd, cr and zn) are studied in the surface sediments of bakhtegan lake, northwest of nyriz city, iran, to assess metal contamination. the average abundance order of trace elements content in bakhtegan lake sediments is cr>ni> v> zn> cu> co> as> pb> mo>cd. the comparison of trace elements concentration in bakhtegan lake sediments with toxicol...

[1] Empirical studies have suggested the existence of a threshold radar reflectivity between nonprecipitating and precipitating clouds; however, there has been neither a rigorous theoretical basis for the threshold reflectivity nor a sound explanation as to why empirically determined threshold reflectivities differ among studies. Here we present a theory for the threshold reflectivity by relati...

Isolated rat hepatocytes bind to synthetic flat polyacrylamide matrices containing covalently attached galactose residues in a sugar-specific and concentration-dependent manner. Cell binding is mediated by the asialoglycoprotein receptor and occurs as a threshold response at or above a critical concentration of sugar in the matrix. Hepatocytes in the presence or absence of serum were able to sp...
