DEVELOPMENT AND VALIDATION OF POTATO LEAF ROLL VIRUS DISEASE PREDICTION MODEL BASED ON ENVIRONMENTAL FACTORS FOR FAISALABAD, PAKISTAN
...or model development. In stepwise regression analysis minimum temperature, relative humidity and rainfall emerged as the main contributing environmental variables for disease development. The model performance was evaluated based on coefficient of determination (R ) and the comparison of observed and predicted disease incidence. Model so developed explained 70% of the variability in disease development and when validated on an independent dataset, the model ex...

...tes. Forward elimination stepwise logistic regression was worked out with the above significantly different variables and their first-order interaction as independent variables. Finally, regression equation with the lower Akaike’s Information Criterion for small sample sizes (AICc) value was regarded as the optimal model. The model indicated that nest-site success of brown-eared pheasants was negatively related to cover of shrubs, and first-order interac...

...rom fetal sheep, and the stepwise digestion by XI collagenase and trypsin was used to isolate MDSCs and were purified by differential attachment technique. Cell morphology were observed using an inverted microscope, and MDSCs proliferation pattern were determined through growth curve analyses. MDSCs were identified by immunofluorescence and RT-PCR, and the immunofluorescence antibody invoved Sca-1, CD34, CD144, Desmin and CD45 which are the makers of MDSCs. Fi...

We recorded 109,026 sightings comprising 94 species, and found that avian diversity indices were positively influenced by the presence of open water, farmland, and alkaline marsh, and negatively by human settlement; and in addition, these relationships were only apparent when scale was considered. We detected the dependence of th...

...’s correlation and stepwise regression techniques were employed for the analysis of data. The association findings showed that BW had a positively high significant association (P < 0.01) with WH (r = 0.94), HG (r = 0.91), RH (r = 0.88), SH (r = 0.90), RW (r = 0.73), and a positive statistical significant correlation (P < 0.05) with EL (r = 0.47), and BL (r = 0.46) in males. On the other hand, BW had a positively high remarkable relationship (P <...

...ture Collection. Through stepwise screening, an apatinib-resistant SCLC cell line (H69/Apatinib) was established. All cell lines were stored in RPMI-1640 medium, which was supplemented with 10% fetal bovine serum, 100 µg/ml streptomycin and 100 U/ml penicillin and kept in humid air containing 5% CO2 at 37°C. The cell assay was performed when the cells were in the logarithmic growth phase. In the cultured H69/apatinib, the IC50 of apatinib was greater...

... and CG (r = 0.877). The stepwise regression results showed that the model using three predictors (BW = -159.57+0.44HH+0.69BL+1.38CG) was the best-fitted model (R2 = 0.814; RMSE = 0.834) for the prediction of BW, followed by using BL+CG, HH+CG, CG, HH+BL, HH, and BL. The correlation results imply that BW might be improved by the enhancement of HH, BL, and CG. In conclusion, the BW could be predicted accurately using the combination of HH, BL, and CG. The findi...

The Pearson’s correlation findings displayed that egg weight (EW) had a highly positive remarkable association (P < 0.01) with egg length (EL), yolk weight (YW), egg width (EWD), albumen weight (AW), shell surface area (SSA), albumen ratio (AR) and egg volume (EV), and a highly neg...

...ied IL-2 was achieved by stepwise dialysis method using urea gradient (8M-0M). Human IL-2 was recovered from 1 litre culture to a purity level of ~95%. In vitro cytotoxic potential of IL-2 on HepG-2 and MCF-7 cell lines revealed that it possess sufficient cytotoxic potential and can inhibit the growth of these cell lines directly. Thus, refolded IL-2 had activity identical to that of authentic IL-2 and enhanced the anti-tumor activity of HepG-2 as compar...

It was concluded that the incidence of malnutrition in hemodialysis patients with end stage renal disease is relatively high, which is closely related to the age, inflammatory state and dialysis adequacy of the patients. According to nutritional risk characteristics of hemodialysis patie...
