Analysis of Factor-VIII-related antigen (vWAg) in normal plasma by crossed immunoelectrophoresis reveals an asymmetric pattern indicative of molecular heterogeneity. This asymmetric pattern apparently results from the presence of multiple molecular forms of VWAg with distinct, though partially overlapping, mobilities on crossed immunoelectrophoresis. Evidence for this conclusion has been obtain...

results mycoflora profiles of fresh and stored rice grains showed that aspergillus species (37.3%, 40.7%) were the predominant fungal agents, followed by fusarium (21.6%, 16.2%), mucor (19.6%, 16.7%) and rhizopus (9.8%, 11.1%), respectively. in hplc analysis, most of the rice samples (96.7%) collected were found to be positive for fb1 with mean levels ranging from not detected to 56.2 mg/kg for...

purpose: to evaluate total plasma homocysteine level during the acute phase of central retinal vein occlusion (crvo) compared with a matched healthy group in iranian population, and determine whether hyperhomocysteinemia is also a risk factor for crvo. methods: a study group contains 54 patients presenting with crvo in recent one month, acute phase of the decease, was compared for fasting total...

conclusions although the results obtained with the use of different methods show an excellent correlation, when one particular sample is tested by different assays, the results are significantly different. it can be concluded that the national standardization program of hba1c measurement is necessary. background hemoglobin a1c (hba1c) testing devices are widely used to evaluate glycemic control...

background : doogh is a fermented beverage in which microbial spoilage is possible. benzoic acid and its salt (sodium benzoate) are added to doogh as antimicrobial preservative to control microbial spoilage. however, the use of this preservative has been prohibited in milk and dairy products such as food and drug administrationand institute of standards and industrial research of iran. thus, th...

Countercurrent immunoelectrophoresis was used to assay bloodmeals to determine the hostspecificity of Anopheles culicifarics species-A and B, collected from areas in Delhi, Uttar piadesh and Bihar. Results indicated the-predominantly zoophagic nature of species A and B with " r.t"tiullv higher degree of anthropophagy for species A. Furth-er, the human blood index was found to be relatei to the ...

High-temperature liquid chromatography (HTLC) is recognized today as a valuable technique in reversed-phase high-performance liquid chromatography (RP-HPLC). Column temperature can play a role in reducing analysis time, modifying retention, controlling selectivity, changing efficiency or improving detection sensitivity. The different effects of high temperatures on reversed-phase separations, t...
