Measures of magnitude and impact of differential item functioning (DIF) at the item and scale level, respectively are presented and reviewed in this paper. Most measures are based on item response theory models. Magnitude refers to item level effect sizes, whereas impact refers to differences between groups at the scale score level. Reviewed are magnitude measures based on group differences in ...

This study was aimed to evaluate the effect of L-ascorbyl-2-polyphosphate as a dietary ascorbic acid source on blood parameters of Caspian brown trout (Salmo trutta caspius), including red blood cell (RBC) count, white blood cell (WBC) and WBC differential. A total number of 600 Caspian brown trout (9.6±0.6 g) fingerlings were randomly distributed in triplicates among five treatments each conta...

Although many studies have reported an association between total white blood cell count and metabolic syndrome, relatively few reports are available on the association between differential white blood cell counts and metabolic syndrome. The medical records of 15,654 subjects (age, median 46, range 14-90 yr; 8,380 men and 7,274 women) who visited the Center for Health Promotion were investigated...

Top Japanese sprinters were evaluated for their physical condition, autonomic function, blood chemistry, differential leukocyte count and blood lactate level before and after short, maximal exercise to explore methods of quantifying their conditioning level. Statistical analysis of data obtained before and 10 min after exercise were used to estimate the athletes’ autonomic capacity during recov...

AIM/BACKGROUND Previous studies have suggested that healthy subjects of African ancestry have lower total white cell counts, neutrophil counts and platelet counts than Caucasian subjects and that, at least among Caucasians, women have higher neutrophil and platelet counts than men. The primary aim of this study was to confirm and quantify the ethnic differences, confirm the sex difference in Ca...

Background: Exposure to environmental toxins such as organophosphates poses a great threat to the health of the public. In this work, we investigated the effects of continuous exposure to dichlorvos (DDVP) on kidney function and hematological parameters, and the possible antidote activity of Nigella sativa oil (NSO). Methods: This research was conducted in 2016, at The Animal Holding and Resea...

The differential white cell counts produced by the Technicon H*1 Autoanalyser in profoundly leucopenic specimens were compared with those carried out by manual differential counting by light microscopy of peripheral blood smears stained with May-Grünwald-Giemsa stain. The correlation achieved allowed the H*1 derived differential count to be reported with confidence.
