Occupational exposure to 1-bromopropane(1-BP) induces learning and memory deficits. However, no therapeutic strategies are currently available. Accumulating evidence has suggested that n-methyl-D-aspartate receptors(nMDARs) and neuroinflammation are involved in the cognitive impairments in neurodegenerative diseases. In this study we aimed to investigate whether the noncompetitive nMDAR antagonist MK801 protects against 1-BPinduced cognitive dysfunction. Male Wistar rats were administered with MK801(0.1 mg/kg) prior to 1-BP intoxication(800 mg/kg). Their cognitive performance was evaluated by the Morris water maze test. The brains of rats were dissected for biochemical, neuropathological,and immunological analyses. We found that the spatial learning and memory were significantly impaired in the1-BP group, and this was associated with neurodegeneration in both the hippocampus(especially CA1 and CA3)and cortex. Besides, the protein levels of phosphorylated nMDARs were increased after 1-BP exposure. MK801 ameliorated the 1-BP-induced cognitive impairments and degeneration of neurons in the hippocampus and ***, MK801 abrogated the 1-BP-induced disruption of excitatory and inhibitory amino-acid balance and nMDAR abnormalities. Subsequently, MK801 inhibited the microglial activation and release of pro-inflammatory cytokines in 1-BP-treated rats. Our findings, for the first time, revealed that MK801 protected against 1-BP-induced cognitive dysfunction by ameliorating nMDAR function and blocking microglial activation, which might provide a potential target for the treatment of 1-BP poisoning.

Understanding climatic effects on cropland water use efficiency at different elevations is imperative for managing agricultural water and production in response to ongoing climate change in climate-sensitive areas with complex topography, such as southwestern China. We investigated climatic effects on cropland water use efficiency in southwestern China at each 100-m elevation bin during 2001–2017. The maximum water use efficiency was 1.71 gC kg^(–1) H_2O for the 1900–1999 m elevation bin under the growing season temperature and precipitation of 14.58±0.32℃ and 965.40±136.45 mm, respectively. The water use efficiency slopes were dominated by the evapotranspiration slopes at elevations below 1999 m but were controlled by the gross primary productivity slopes at elevations above 2000 m. This difference was caused by the substantial responses of evaporation to climate change at lower elevations and the increased climatic sensitivity of gross primary productivity at higher elevations. In comparison to those at other elevations, croplands at lower elevations were more vulnerable to extreme drought because of the dominant role fluctuating evapotranspiration played in water use efficiency. The findings will improve cropland water management in the study area.

Objective To investigate the effects of YOD1 overexpression on the proliferation and migration of human oral keratinocytes（HOKs）, and to clarify whether the mechanisms involve transforming growth factor-β（TGF-β） signaling. Methods HOKs were transfected with the plasmid p EGFP-n3-YOD1 containing YOD1. The mR nA levels of YOD1 and TGF-β were determined by q PCR. The protein expressions of YOD1, TGF-β, Smad2/3, Smad4, and phospho-Smad2/3 were determined by western blotting. Cell proliferation and migration were evaluated by Cell Counting Kit-8 assay and wound healing assay, respectively. Results The m RnA and protein levels of YOD1 were higher in HOKs transfected with YOD1. YOD1 overexpression significantly enhanced the migration of HOKs. The mR nA and protein levels of TGF-β3 were increased by YOD1 overexpression. HOKs transfected with YOD1 exhibited increased phospho-Smad2/3 levels. Conclusion YOD1 overexpression enhances cell migration by promoting TGF-β3 signaling which may play an important role in lip and palate formation. YOD1 mutation may contribute to aberrant TGF-β3 signaling associated with decreased cell migration resulting in nSCLP.

Cell adhesion plays pivotal roles in the morphogenesis of multicellular *** cells form several types of cell-to-cell adhesion,including zonula occludens(tight junctions),zonula adhaerens(adherens junctions),and macula adhaerens(desmosomes).Although these adhesion complexes are basically observed only in epithelial cells,cadherins,which are the major cell adhesion molecules of adherens junctions,are expressed in both epithelial and non-epithelial tissues,including neural tissues(Kawauchi,2012).The cadherin superfamily consists of more than 100 members,but classic cadherins.

A totally structure-determined organosilver(I) metal-oganic framework(MOF) of [{Ag_(18)(CF_3COO)_(18)(H_2O)_2}{Ag_4(erlotinib)_4}]_n·7nCH_3OH·3nH_2O(1) was first synthesized by the self-assembly of erlotinib drug ligand and silver salts in the study. 1 formed a nbO-like 3D network, which was built from Ag(I)-erlotinib induced chains and 18-core silver(I) nanoclusters. When 1 was dispersed in methanol solution, it formed derivative nanoparticles(1-nPs) with the average size of 3.81 nm. Silver(Ⅰ) ion is an efficient reactive oxygen species(ROS) evocator, whereas the erlotinib ligand possesses the targeting activity towards tumor cells. Therefore, IC_(50) values of 1-nPs for A549 and MRC-5 cells were respectively 0.97 and 7.28 μM, which were lower than IC_(50) value of erlotinib. It should be noted that the 7.5-fold higher inhibition effect on A549 cells allows 1-nPs to be a potential targeting anticancer drug for curing lung cancer. The study opens a new avenue to design anticancer drugs based on organosilver(I)MOF derivatives that can realize the value-added reactivity by combining clinical drugs with ROS-inductive silver(Ⅰ) ion.
