The possibility of application of 4-nitrocatechol (4-NC) - tetrazolium salt - organic solventsystems for liquid-liquid extraction-spectrophotometric vanadium (IV and V) speciation wasstudied. Six commercially available tetrazolium salts (2,3,5-triphenyltetrazolium chloride (TTC),3-(2-naphtyl)-2,5-diphenyltetrazolium chloride (Tetrazolium Violet, TV); 3-(4,5-dimethyl-2-thiazol)-2,5-diphenyltetra...

On induction of anesthesia (for intubation), the patient hemodynamics became very unstable prompting the initiation of both Epinephrine and Nor-Epinephrine Intra-venous (IV) infusions. Glucose 10% IV infusion and Insulin IV infusion were also started. The pre-transfer management also included Hydrocortisone IV justified by the marked hemodynamic instability and mediocre response to inotropic su...

in this research, first was identified suitable regions (considering ecological indexes) for intensive and extensive outdoor recreation and their various degrees using the usual tourism ecological model and applying gis. results showed that 297.223 hectares of park area have class 1 of extensive outdoor recreation potential, 86.465223 hectares class 2 of extensive outdoor recreation potential, ...

Background: Parents play a key role in the assessment and management of pain. There is not much knowledge about parental viewpoint or their participation in the pain management of the neonates admitted to the intensive care units. The present study was conducted with the aim of assessing the viewpoints of mothers about pain management of the neonates/ infants   admitted to Tabriz hospitals. Me...

It is unclear at present which mathematical modeling Kt/V(urea) is valid for assessment of both long mild hemodialysis (HD) and short intensive HD, the single-pool modeling Kt/V (Kt/Vsp) based on the pre- and postdialysis serum urea concentrations, double-pool modeling Kt/V (Kt/Vdp) based on the predialysis concentration and the estimated postdialysis equilibrated concentration, or Kt/V calcula...

Infants of very low birth weight (VLBW) are, for the most part, potentially normal at birth but, because of immaturity of structure and function of many organs, are at risk from death or permanent handicap. A recent survey of world literature suggested that the improvement in the outcome for these babies, which has occurred over the past ten years, was due to perinatal intensive care. To date, ...

Results A total of 372 patients ≥ 90 years were admitted to the intensive care units (ICUs). The majority (66.7%) of patients were admitted because of an emergency, and of which, half underwent unscheduled surgery. 39.8% needed support by mechanical ventilation and vasoactive drugs, 1,9% received renal replacement. ICU and hospital mortality rates were 18.3% and 30.9%, respectively. Mortality a...
