为了揭示妊娠合并糖尿病诱发胚胎先天性神经管缺陷的分子机制,并探讨其有效的防治方法。实验选用6个实验组的Sprague dawley大鼠:第1组为常规饲养的正常对照组;第2组尾静脉注射65mg/kgStreptozotocin(STZ)构建妊娠合并糖尿病、且诱发先天性神经管缺陷的实验组大鼠;第3组为STZ构建的糖尿病、但胚胎不伴有先天性神经管缺陷的大鼠模型;第4、5、6组为STZ构建的糖尿病治疗组大鼠,每日分别给予80μg/mL花生四烯酸(arachidonicacid,AA)、400mg维生素E、抗氧化剂(维生素E)和不饱和脂肪酸(safloweroil)混合物cocktail治疗。于妊娠第12天取出各组胚胎,解剖显微镜下进行形态学分析;提取卵黄囊细胞蛋白质,应用特异性抗磷酸化抗体进行免疫共沉淀及Western印迹,对mAP激酶信号途径上各蛋白激酶ERK1/2、JNK1/2、RAF 1活性进行分析。与正常对照组相比,妊娠合并糖尿病诱发的先天性神经管缺陷胚胎中(第2组),ERK1/2蛋白激酶活性显著下降,其上游RAF 1活性相应降低;与此相反,JNK1/2活性明显升高。在给予花生四烯酸、维生素E补充物治疗后,通过调节mAP激酶信号通路蛋白激酶活性,逆转了胚胎神经管缺陷的发生。妊娠合并糖尿病诱发的胚胎先天性神经管缺陷的发生,与mAP激酶信号传导机制异常密切相关。

A major concern from the scientific community has been raised since evidence of Bisphenol A(BP-A)can leach out from the products where they are incorporated as well as its endocrine disrupting effects observed in animals and ***-A and several related chemicals such as Bisphenol AP(BP-AP),Bisphenol B(BPeB),Bisphenol S(BPeS),Bisphenol AF(BP-AF),Bisphenol(BPeP),Bisphenol Z(BP-Z)were analyzed in this ***-A and BP-S were the only bisphenols detected in the samples analyzed in this *** m.d.an(range;mean)concentrations of BP-A found in this study was 321 ng/g(11-200932;4893 ng/g).The analysis was carried out by sonicating 0.1 g of a cryo-milled sample aliquot in methanol followed by UPLC-mS/mS *** concentrations of BP-A were found in several products labeled as BP-A free such as nursing bottles which are particularly problematic from the children's exposure point of *** study presents the first reliable bisphenols in children's toys and baby products commercialized in the m.d.le *** is,however,a need to continue monitoring these compounds,especially in low-cost toys,and the so-called BP-A-free products,which appear to have high levels of target contaminants and can pose an exposure risk for infants and children in the region.

One of the most important parameters in meteorology is the mean wind proﬁle in the tropical cyclone boundary *** vertical proﬁle of wind speed and wind direction were measured during the period of the Nisarga cyclone from may 31st,2020,to June 5th,2020,using the newly installed Phased Array doppler Sodar system at the Center for Space and Atmospheric Science(CSAS),Sanjay Ghodawat University,Kolhapur(16.74◦N,74.37◦E;near India's western coast).Our analysis revealed that the maximum mean wind speed was 17 m/s on June 3,2020,at 10:00 *** also shows the change in wind direction from southwest to southeast on June 2 and 3,*** high-resolution reanalysis data in the domain,0–25◦N,65–110◦E,during the period from may 31st to June 5th,2020,revealed the variation of the atmospheric pressure of the Nisarga cyclone from 1000 to 1008 hPa,sea surface temperature(SST)between 30◦C and 31◦C,outgoing longwave radiation(OLR)between 100 and 240 Wm-2,wind speed between 3 and 15 m/s,and low values of vertical wind shear(VWS)were observed to the north of Nisarga *** observations may provide more insights for the study of boundary layer turbulence during cyclonic activities.
