Background:Administration of progesterone(P4)to ewes during the first 9 to 12 days of pregnancy accelerates blastocyst development by day 12 of pregnancy,likely due to P4-induced up-regulation of key genes in uterine epithelia responsible for secretion and transport of components of histotroph into the uterine *** study determined if acceleration of blastocyst development induced by exogenous P4 during the pre-implantation period affects fetal-placental development on day 125 of *** ewes(n=35)were mated to fertile rams and assigned randomly to receive daily intramuscular injections of either corn oil vehicle(CO,n=18)or 25 mg progesterone in CO(P4,n=17)for the first 8 days of *** ewes were hysterectomized on day 125 of pregnancy and:1)fetal and placental weights and measurements were recorded;2)endometrial and placental tissues were analyzed for the expression of candidate mRNAs involved in nutrient transport and arginine metabolism;and 3)maternal plasma,fetal plasma,allantoic fluid,and amniotic fluid were analyzed for amino acids,agmatine,polyamines,glucose,and ***:Treatment of ewes with exogenous P4 did not alter fetal or placental growth,but increased amounts of aspartate and arginine in allantoic fluid and amniotic fluid,*** that received exogenous P4 had greater expression of mRNAs for SLC7A1,SLC7A2,SLC2A1,AGmAT,and ODC1 in endometria,as well as SLC1A4,SLC2A5,SLC2A8 and ODC1 in *** addition,AZIN2 protein was immunolocalized to uterine luminal and glandular epithelia in P4-treated ewes,whereas AZIN2 localized only to uterine luminal epithelia in CO-treated ***:This study revealed that exogenous P4 administered in early pregnancy influenced expression of selected genes for nutrient transporters and the expression of a protein involved in polyamine synthesis on day 125 of pregnancy,suggesting a‘programming’effect of P4 on gene expression that affected the composition of nutrients in f

Primary and Secondary microplastic and Nanoplastic Regulations: Perspectives on Water Industry Impacts

引用

Journal of Environmental Protection 2024年第6期15卷 697-715页

作者： Shirin Estahbanati Giridhar Upadhyaya martha J. m. Wells katherine Y. Bell Brown and Caldwell New York NY USA Brown and Caldwell Irvine CA USA EnviroChem Services Cookeville TN USA Brown and Caldwell Nashville TN USA

Plastic pollution, both primary and secondary, is an environmental challenge, prompting regulatory actions at global and regional levels. With increasing research about the impacts of micro- and nanoplastics on ecosystems and human health, governments worldwide have undertaken efforts to address this issue. The global community has advanced regulatory efforts that have led to the implementation of national laws or regulations in numerous countries. These measures ban or restrict the use of primary and secondary microplastics and nanoplastics. An overview of global and European regulatory frameworks is presented to provide context for the United States (US). In the endeavor to document plastics regulation development in the US, a description of regulatory agencies and their roles in advancing policy and rules as well as future direction and areas for improvement in regulating plastics are introduced. A discussion of what emerging regulations mean to utilities and industries is also provided along with a comparison of regulatory frameworks.
