Abstract
Stroke is one of the devastating clinical conditions that causes death and permanent disability. Its occurrence causes the reduction of oxygen and glucose supply, resulting in events such as inflammatory response, oxidative stress, and apoptosis in the brain. Microglia are brain-resident immune cells in the central nervous system (CNS) that exert diverse roles and respond to pathological process after an ischemic insult. The discovery of fibroblast growth factors (FGFs) in mammals, resulted to the findings that they can treat experimental models of stroke in animals effectively. FGFs function as homeostatic factors that control cells and hormones involved in metabolism, and they also regulate the secretion of proinflammatory (M1) and anti-inflammatory (M2) cytokines after stroke. In this review, we outline current evidence of microglia activation in experimental models of stroke focusing on its ability to exacerbate damage or repair tissue. Also, our review sheds light on the pharmacological actions of FGFs on multiple targets to regulate microglial modulation and highlighted their theoretical molecular mechanisms to provide possible therapeutic targets, as well as their limitations for the treatment of stroke. DATA AVAILABILITY: Not applicable.

Abstract
Water poverty is among the most significant global challenges and severely restricts the sustainable development of societies and economies, especially in the world's arid regions. Many countries have attempted to address this challenge. Market-based trading mechanisms represent an essential method of resolving the problem of water shortages and alleviating water poverty. Based on a quasi-natural experiment of water rights trading pilots in China, this study uses panel data from 31 provinces (municipalities) from 2009 to 2019 to explore the impact of water rights trading pilot policy on water poverty through a difference-in-differences (DID) model. The research results show that such policies can effectively alleviate water poverty by improving water-saving irrigation technology, promoting industrial and agricultural water trading, and optimizing the industrial structure. Additionally, dynamic effect and spatial heterogeneity analyses show that the water rights trading pilot policy have long-term effects and have a stronger mitigation effect on the western region of China compared with the central and eastern regions. Therefore, the Chinese government should not only further expand the implementation scope of these policies but also adjust measures according to local conditions to accurately and effectively implement such policies in different regions. Our study provides insights into water policies in China that can better manage natural resources and reduce water poverty in the arid areas around the world.

Abstract
The N-alkylation reaction of pyrazole derivatives with halomethanes was studied using density functional theory (DFT). The hybrid method B3LYP was employed, along with an ECP basis set such as LANL2DZ for halogen atoms (X = Cl, Br, I) and the 6-311 + G(d,p) basis set for all other atoms. In order to predict the specific site at which the pyrazole derivatives interact with halomethanes, local reactivity descriptors such as the Fukui functions were calculated. Detailed analysis of transition-state energies showed that alkylation occurred at the nitrogen atom N2 in the pyrazole derivatives, in agreement with the chemical reactivity results. The reaction mechanisms were elucidated by performing intrinsic reaction coordinate (IRC) calculations that considered the effects of the solvent and the species of halogen in the halomethane.
