Background. To assess the ability of mid-trimester sFlt-1/PlGF ratio for prediction of preeclampsia in two different Arabic populations. Methods. This study measured levels of sFlt-1, PlGF, and sFlt-1/PlGF ratio at midtrimester in 83 patients who developed preeclampsia with contemporary 250 matched controls. Results. Women subsequently developed preeclampsia had significantly lower PlGF levels and higher sFlt-1 and sFlt-1/PlGF ratio levels than women with normal pregnancies (P < 0.0001 for all). Women who with preterm preeclampsia had significantly higher sFlt-1 and sFlt-1/PlGF ratio than term preeclamptic women (P = 0.01, 0.003, resp.). A cutoff value of 3198 pg/mL for sFlt-1 was able to predict preeclampsia with sensitivity, specificity, and accuracy of 88%, 83.6%, and 84.7%, respectively, with odds ratio (OR) 37.2 [95% confidence interval (CI) 17.7–78.1]. PIGF at cutoff value of 138 pg/mL was able to predict preeclampsia with sensitivity, specificity, and accuracy of 85.5%, 77.2%, and 79.3%, respectively, with OR 20 [95% CI, 10.2–39.5]. The sFlt-1/PIGF ratio at cutoff value of 24.5 was able to predict preeclampsia with sensitivity, specificity, and accuracy of 91.6%, 86.4%, and 87.7%, respectively with OR 67 [95% CI, 29.3–162.1]. Conclusion. Midtrimester sFlt-1/PlGF ratio displayed the highest sensitivity, specificity, accuracy, and OR for prediction of preeclampsia, demonstrating that it may stipulate more effective prediction of preeclampsia development than individual factor assay.

, to evaluate the effect of storage methods (normal storage in cotton bags and sealing storage in plastic jars and metal packages) and fumigation with phosphine at 0, 3, 5 and 7 tablets/m 3 on storage efficacy, germination and seedlings parameters of wheat during different storage periods (3, 6 and 9 months after harvesting). The most important results can be summarized as follows:-Increasing storage periods of wheat seed from 3 to 6 and 9 months significantly affected storage efficacy characters (insect infestation and weight loss percentages), final germination percentage and seedling parameters (seedling length, root length, shoot length and seedlings fresh and dry weights).-The best results of storage efficacy of wheat recorded when sealed stored in metal packages, followed sealed stored in plastic jars and lastly in cotton bags. Whereas, highest germination and seedling parameters were recorded when sealed stored in metal packages, followed by normal stored in cotton bags and lastly stored in plastic jars.-The lowest percentages of insect infestation and weight loss in wheat seeds were obtained from fumigation with phosphine at the rate of 7 tablets/m 3. While, maximum values of germination and seedling parameters were obtained from fumigation with phosphine at the rate of 5 tablets/m 3. This study recommended that fumigation wheat seeds before storage in metal packages with phosphine at the rate of 5 tablets/m 3 under the environmental conditions of the experiment in Mansoura, Dakahlia Governorate, Egypt.
