A novel method avoiding the complex transfer process is proposed to directly grow low-defect and few-layer graphene on different insulating substrates（SiO2, Al2O3, etc.） by remote catalyzation of Cu nanoparticles（NPs） using ambient pressure chemical vapor deposition（APCVD）. The insulating substrates with special structure are used as templates to grow wrapped graphene sheets with special *** graphene species are obtained by removing the substrates. The prime feature of the proposed method is using Cu NPs as catalyst rather than metal foils. The Cu NPs play an important role in the remote catalyzation during the nucleation of graphene. This method can improve the quality and relatively decrease the growth temperature of the graphene on the insulating substrates, which displays the great potential of APCVD direct growth of graphene on dielectric substrates for electronic and photovoltaic applications.

Bifenthrin（BF） is a pyrethroid insecticide that is widely used in agriculture, horticulture, and for residential purposes. However, few studies addressing the reproductive toxicity of BF on fishes are available. The present study was conducted to investigate the effects of BF on testicular development in Sebastiscus marmoratus and to gain insight into its mechanism. After exposure to 1, 10 and 100 ng/L BF for 50 days, there was a reduced number of mature sperm and an abundance of the late stages of spermatocysts in the testes. The levels of 17β-estradiol and testosterone were decreased significantly after BF exposure. The activity of caspase-3 was increased in a dosedependent manner after BF exposure, TUNEL assay indicated that BF exposure resulted in the occurrence of apoptosis in the testes, which might be main reason for the inhibition of spermatogenesis.

Grass carp reovirus（GCRV）,a member of the genus Aquareovirus in the family Reoviridae（Attoui H,et al,2002）,is one of the most virulent aquareoviruses iden-tified so far,leading to high fatality rates（up to 85%）of fingerlings and yearlings of grass carp（Fang Q,et al,2007）.No commercial vaccines against GCRV infection have been developed as yet.

White tea encompasses a number of teas unique to eastern Fujian in China. Although white tea extracts have been reported to result in cancer cell apoptosis, to date, few studies have evaluated the mechanism of such apoptotic induction. A transcription factor that plays a critical role in cell apoptosis, NF-κB p65, is also likely critical by which white tea extracts induce cancer cell apoptosis. In this study, white tea aqueous extract (WTAE) was added to BEL-7402 and Hela cell media and NF-κB p65 activation was evaluated using western blotting and immunofluorescence. Results revealed that the phosphorylation of IKBα and p65 decreased in both cell lines after WTAE treatment. And the nuclear translocation of NF-κB p65 in both cell lines was also reduced with the WTAE treatment. NF-κB p65 inhibition was noted to accelerate apoptosis. Our findings suggest that NF-κB p65 was an important modulator in WTAE-induced apoptotic signal transduction and it acted as a negative regulator of apoptotic induction in BEL-7402 and Hela cancer cell lines.

频繁发生的森林大火对亚马逊热带雨林造成了大面积破坏,获取不同年份的火灾影响范围以及植被破坏情况,有助于了解该地区火灾时空演变规律以及火灾与植被的相互作用关系,进而探究火灾发展机理,为防灾减灾提供科学依据。为此,利用2015~2019年MODIS植被指数产品与地表温度产品,构建MODIS全球扰动指数模型(MGDI),结合火点数据(以下统称MOD14A1)、植被连续场数据(Vegetation Continuous Field,VCF)提取1000 m分辨率下的燃烧范围和燃烧强度,并分析研究区域5年内的火灾分布时空规律。实验结果表明:(1)火灾主要分布在巴西中部以及巴西与玻利维亚的交界处,占燃烧区总面积的67%左右;(2)燃烧范围以及燃烧强度的综合信息显示火灾整体呈现出“升—降—升”的趋势;(3)火灾多发生于灌木草地(50%以上)以及阔叶林(30%),且火灾多发在旱季;在全球变暖大背景下,火灾发生频率呈上升趋势;(4)人类活动范围扩张、不合理农业开垦、森林砍伐导致研究区内草地退化严重,农业用地以及建筑用地逐年上升,在一定程度上为火灾的发生、传导提供了良好的条件。
