conclusions the pattern of pretreatment with o2 could change this potential and highly protective strategy against cp-induced nephropathy to an ineffective or even mildly deteriorating one. therefore, o2 administration before cp injection to patients with cancer, for therapeutic purposes or as a preconditioning approach, should be performed and investigated with caution until exact effects of d...
The reaction of the Co(II) complex with the rigid bispidine ligand L1 with two tertiary amine and two pyridine donors, [Co(II)(L1)(OH2)2]2+, with H2O2 and O2 produces [Co(II)(L2)(OH2)2]3+, where L2 is demethylated at one of the amine donors, and CH2O.
We hypothesized that breathing hypoxic, hypercapnic, and CO-containing gases together reduces maximal aerobic capacity (Vo2max) as the sum of each gas' individual effect on Vo2max. To test this hypothesis, goats breathed combinations of inspired O2 fraction (FiO2) of 0.06-0.21 and inspired CO2 fraction of 0.00 or 0.05, with and without inspired CO that elevated carboxyhemoglobin fraction (FHbCO...
The research on decomposition characteristics of SF6 and its by-products have great significance to the operation, maintenance, condition assessment fault diagnosis power equipment. In this paper, particle composition models SF6, SF6/polytetrafluoroethylene (PTFE), SF6/PTFE/O2, SF6/PTFE/H2O, SF6/PTFE/O2/H2O were established by using Gibbs free energy minimization method, effects trace H2O O2 im...
in this study, the structures, the ir spectroscopy, and the electronic properties of auncum (n+m≤5) bimetallic clusters were studied and compared with those of pure gold and copper clusters using the generalized gradient approximation (gga) and exchange correlation density functional theory (dft). the study of an o2-auncum system is important to identify the promotion effects of each of the two...
using the gaussian 2003 software and mp2 /6 – 311+ g method for the c2h4 : o2, co:cl2 andco2:co2 pairs and mp2/6-311++g** method for the co2:h2o pair and b3lyp/6-31g methodfor the o2:o2 pair the optimized interaction energies between two considered pair molecules ofstudied gases(c2h4:o2, co:cl2, co2:h2o, o2:o2 and co2:co2 pairs) as a function of thedistances between the centers of two considere...
improving barrier properties through the use of nanocomposites is an important area of research, especially for the food packaging industry. in this work, titanium dioxide (tio2 )/low density poly ethylene (ldpe) nanocomposites were synthesized as the oxygen barrier layers through the co-extrusion process. the oxygen permeability of the nanocomposite with 4% of tio2 decreased for about 16% comp...
one way to increase the shelf life of agriculture products is using of controlled atmosphere storages. in order to obtain the controlled gas components, an equipped cold store with cooling system and atmosphere controller system designed and constructed. the injection of co2, o2 and n2 were controlled automatically into the store by programable logic control (plc). the store was a laboratory re...
A micro-Fick method has been developed to measure the O2 consumption of different regions of an organ. The method was tested in isolated dog gracilis muscle and consisted of microspectrophotometric determination of arterial and venous O2 saturation in quick frozen tissue to determine O2 extraction and flow measured with 85Sr-labeled microspheres, with O2 consumption calculated from the product....
