    Rheumatoid arthritis (RA) is related to alterations in different inflammatory and connective tissue biomarkers. The diagnostic values and the factors affecting these biomarkers are conflicting. In the present study, a bone-related composite (B-composite), made from the z-score of stromelysin-1 (MMP3), colony-stimulating factor 2 (CSF2), and osteopontin (OPN), and I-composite, reflecting immune activation, made from the z-score of tumor necrosis factor-α (TNFα), interferon-γ (INFγ), and vascular endothelial growth factor-A (VEGF) were examined in RA patients. The biomarkers were measured by ELISA technique in 102 RA patients and 58 age-matched healthy control subjects. Serum MMP3, TNFα, IFNγ, and CSF2 showed significant elevation in RA patients. Multivariate general linear model (GLM) analysis revealed a significant high effect of diagnosis on biomarkers' level (partial η2 = 0.415). Duration of disease is significantly associated with VEGF, OPN, and B-composite and negatively correlated with TNFα. B-composite is significantly associated with CRP. A significant fraction of the DAS28 score variance can be explained by the regression on zlnINFγ. The variance in the CRP was explained by zlnOPN and B-composite. More than half of anti-citrullinated protein antibodies (ACPA) variation can be explained by the regression on serum MMP3 and I-composite. The top 3 sensitive predictors for RA disease are INFγ, MMP3, and TNFα. B-composite is associated with the duration of disease and CRP. At the same time, I-composite is negatively associated with the ACPA level. The biomarker composites have potential use as RA disease characteristic biomarkers

    In latest years in agricultural sector, physical techniques based on magnetic field are being designed. The present work studied the impact of magnetic field on the germination of fresh and partially-aged Panicum miliaceum L. (PM) seeds. The germinated PM seeds were categorized into 6 groups. Groups 1,2 and 3 were fresh seeds, and Groups 4, 5 and 6 (LV30%) were left for 6 days to lose about 30% of their viabilityLV30% seeds. Groups 1 and 4 were normal unexposed seeds. Groups 2 and 5 were seeds exposed to magnetic field intensity of 100mT, while those of 3 and 6 to 200mT for 60 minutes. Germination was monitored on days 2, 5, 7, 10, 12, 14 and 16. The effect of magnetic field on the % germination, growth characteristics of radical and shoot, protein concentration and peroxidase activity in fresh and LV30%were studied. Both the exposed and unexposed seeds lost their viability by 16 days of ageing in fresh and 14 days in (LV30%). Exposed seeds to magnetic fields 100 and 200 mT revealed significant increase in the length of root and shoot compared to normal unexposed seeds. The magnetically exposed aged seeds had significantly higher protein than in the unexposed aged seeds. The peroxidase activity decreased with ageing and the magnetically exposed seeds showed higher activity than the corresponding aged unexposed normal seeds. The present study suggests the magnetic field could accelerate the germination of PM seeds, accelerate their growth characteristics and increase soluble protein content. In addition the peroxidase activity significantly improved

    The study includes two main groups; the first group consists of (90) during delivery women, while the second consists of (90) new born children. The two groups are divided into other subgroups depending on whether they are anemic and non anemic. The first group contains (66) anemic women and (24) non anemic women, While the second group contains (23) anemic newborn and (67) non anemic new born. Total levels of protein and cholesterol have been checked in the subgroups in addition to the effect of anemia on these variables and the changes in total cholesterol and protein levels in regard to weight of the newly born. Variations of these variables depending on sex in the subgroups of newly born have also been checked. The study has revealed that total levels of cholesterol in during delivery anemic women were significantly high in comparison with their levels in non anemic women, their rates range (186 ±18.51) and (163±23.54) mg/dl for each of the two groups, respectively. Moreover, total protein levels were higher in non anemic women than in anemic women ranging (6.97±0.76) and (6.16±0.6) gm/dl, respectively (p < 0.05). Total cholesterol levels in anemic newborn were not significantly different from non anemic children, whereas total protein levels in non anemic children were higher compared with anemic children , rates rang (7.59±0.72) and (6.69 ±0.91) respectively(p<0.05). As for the relationship between the sex of the child and the studied biochemical variables in the sub groups, child sex had no effect on total cholesterol levels, whereas total protein levels varied; Differences were significant between male and female anemic children, while differences were not significant between male and female non anemic children. Also differences were significant between anemic and non anemic male children, whereas they were significant between anemic and non anemic female children (p<0.05). The study has also shown that weights of non anemic children were higher in comparison with anemic children, they were (3.4±0.38) and (3.02±0.47) respectively (p<0.05). Differences in weight between female and male anemic children were not significant; also they were not significant in male and female non anemic children. Differences in weight between anemic and non anemic children were significant; also they were significant between anemic and non anemic female children. There was a difference in the relationship between weights of anemic and non anemic children and total levels of protein and cholesterol in female and male children. In non anemic children, the relationship between total protein levels and the weight of male and female children was slightly significant (r= 0.357), while it was not significant in terms of total cholesterol levels with weights of female and male children. There was a reversible relationship between total protein levels in anemic male children and their weights (r=-0.448), while in female children the relationship was slightly significant(r=0.313). Total cholesterol levels in anemic male children had a high significant relationship (r=0.914) with their weight, while it was not significant in anemic female children
