Background: Blood hemoglobin can be damaged by toxins such as lead. Thus, this study was carried out to assess its blood hemoglobin concentration in the staff of Kermanshah Oil Refinery that had been exposed to lead components. Methods: In this study, 150 workers at Kermanshah Oil Refinery were selected as the case group and 70 workers of textile industry factory were chosen as the control gr...

Hematologic parameters were studied in giant Canada geese (Branta canadensis maxima), mallard ducks (Anas platyrhynchos platyrhynchos) and various species of diving ducks at seasinal intervals throughout the year. Highest values for packed cell volume, hemoglobin content and erythrocyte counts were found in the winter and pre-nesting periods. Mean corpuscular volume and mean corpuscular hemoglo...

alpha thalassemia (α-thal) is relatively common worldwide. most carriers are defective in either one or two alpha globin genes out of four functional ones, with deletions being more common than point mutations. the hematologic features are very important for the selection of the appropriate molecular tests while determining the genotype. the aim of this study was to compare hematologic features...

AIM In order to supply a scientific basis for uniting the normal reference value standard of hemoglobin of Chinese middlescent women. METHODS A research is made about the relationship between the normal reference value of 25,917 examples of hemoglobin of middlescent women and altitude in 268 areas in China, the normal reference values of hemoglobin of middlescent women are determined by the h...

The reaction of hemoglobin with oxygen has been studied by stopped flow methods, and, under suitably restricted conditions, it can be adequately represented by a system of four consecutive reversible reactions. The numerical values given to the eight rate constants permit a satisfactory fit to combination and dissociation velocity data, and yield an equilibrium curve of the appropriate form. Th...

Developing countries have embarked on the promotion of “ICT access for all” through subsidized Information and Communication Technologies (ICTs), especially in underserviced areas of such countries. The main aim of the “ICT access for all” is to extend the communication services to the large areas of underserviced regions through subsidized communication services. In some instances, subsidies m...

If uniform coding (Gödelization) of potentially infinite sequences of numbers can be performed in PSPACEF, then PSPACE = EXPTIME 6= EXPSPACE = 2-EXPTIME, and, for all p, we have p−EXPSPACE = p+1-EXPTIME; if it can be performed in LINSPACEF, we also have LINSPACE = DTIME(2); the proof fails, when relativized to oracle-TM’s. A by-product of this research is that PTIMEF is not closed under number-...
