Cellular hypoxia triggers a homeostatic increase in mitochondrial free radical signaling. In this study, blood was obtained from the radial artery and jugular venous bulb in 10 men during normoxia and 9  hours hypoxia (12.9% O(2)). Mitochondrial oxygen tension (p(O(2))(mit)) was derived from cerebral blood flow and blood gases. The ascorbate radical (A(•-)) was detected by electron paramagnetic...

testosterone level was determined in six different populations of iran using saliva steroid assay. significant difference was observed in morning and afternoon testosterone level of the same individual (p>0.00l) significant difference was also noticed among different regions studied (p>0.00 1). comparisons between alcoholics and nonalcoholic as well as smokers and nonsmokers showed significant ...

Introduction: Boron neutron capture therapy (BNCT) is recommended to treat the glioblastoma tumor. It is well known that neuron beams are more effective treatment than photon beams to treat hypoxia tumors due to interaction of neutron with nucleus and production of heavy particles such as 7Li and alpha particle. In this study to evaluate the suitability of BNCT for treating of ...

SUMMARY  An abnormal increase in serum potassium afte-r administration of suxamethonium is known to occur in the treatment of burns, trauma, teta­nus and neurological disorders. A table shows how long this abnormal reaction lasts approxi­mately in the different categories. A few cases of cardiac arrest following suxamethonium in­jection are described in detail. The pa;thogene­sis of this abnor...

Der Umgang mit Komplexität von Unternehmensarchitekturen, sowohl bei der Erfassung des Ist-Zustands als auch bei der Evolution der jeweiligen Architektur, ist inhärenter Kernbestandteil des Enterprise Architecture Managements. Paradigmen bestimmen dabei im Laufe der Zeit die charakteristische Ausprägung von Unternehmensarchitekturen und bedingen die kritische Überprüfung und möglicherweise auch...

background and objectives: numerous procedures in biology and medicine require the counting of cells. direct enumer- ation of colony forming units (cfus) is time-consuming and dreary accurate cell counting on plates with high numbers of cfus is error prone. in this study we report a new indirect cell counting method that was developed based on the use of redsafe fluorometric assay. the usefulne...
