针对传统苯二甲酸废水处理工艺存在甲烷产率低、颗粒污泥流失严重、化学需氧量(COD)去除率低的问题,构建了新型UASB-MBR组合式反应器,并综合考察了组合式反应器运行稳定性、甲烷转化效率和污泥特性的变化。实验结果表明,废水pH值和总碱度始终维持在厌氧微生物适宜生存的范围,出水氧化还原电位(ORP)值始终维持在理想厌氧系统ORP小于-330mV范围内,此条件说明UASB-MBR组合式反应器可以长期稳定运行。在反应器运行的第一周期,COD去除率约为61.2%,甲烷产率约为0.7L·(m^(3)·d)^(-1)。当废水进入第二周期后,在乙二醇作用下,COD去除率和甲烷产量均有所提升,出水时分别为75.5%和1.05L·(m^(3)·d)^(-1)。运行稳定阶段,生物气中CH_(4)含量约为70%~80%。第二周期引入乙二醇后,提供了微生物生长的基质,加速细胞增殖与代谢,同时还可刺激微生物释放EPS,增强污泥的稳定性。

Lead-halide perovskite nanoparticles（LHP NPs） are highly promising materials for next-generation displays and solid-state lighting due to their exceptional optical properties. However, their inherent instability presents a significant challenge. Recent advances have demonstrated that optoelectronic devices based on monolayer nanoparticle films exhibit both high luminescence efficiency and long-term *** research demonstrates that mobility limitations and anisotropic alignments in CsPbBr3nanocube monolayer films are key to their stabilization, hindering spontaneous growth through face-to-face fusion and resulting in the formation of connecting necks in a diagonal direction. Introducing laser irradiation confirmed this by significantly accelerating nanocubes growth, increasing mobility, and enhancing local structural ordering, leading to larger and more regularly shaped nanosheets. Fourier transform infrared spectroscopy and energy dispersive spectroscopy line-scan analyses indicated that laser irradiation did not disrupt the ligand structure. Transmission electron microscopy and correlative cathodoluminescence electron microscopy revealed the effects of post-growth and heterogeneous structures, including enhanced luminescence and inhomogeneous intensity in the nanosheets. These findings deepen the understanding of the post-growth mechanism of monolayer nanoparticles and the structure-emission correlation and highlight the unique role of laser irradiation in directing the formation of well-defined and regular nanostructures.

TCP转录因子家族是植物特有的基因家族,处于植物多种信号传导途径的中心节点位置,在各种信号传导途径的交叉处起重要作用,调节植物关键的生理生化过程。利用番茄的基因组测序数据,我们对番茄全基因组的TCP基因进行筛选、鉴定和分析。番茄基因组中共有36个TCP基因。这些基因的蛋白质特征,如大小和等电点,差异较大。应该与TCP基因处在信号传导网络的节点,需要与各种各样的蛋白质特异性结合有关。番茄TCP基因结构较为简单,一般不含内含子。但是三号和六号染色体上的9个TCP基因,有5个基因带有一个内含子。系统进化分析表明这五个基因亲缘关系较近。番茄与拟南芥、水稻TCP家族的系统进化分析表明,番茄的全部TCP基因和水稻的基因亲缘关系更近。水稻TCP基因的功能信息,可以给我们提供番茄对应基因的功能信息。

Surveillance recommendations for gastric cancer（GC） in current guidelines focused on advanced precancerous lesions and were based on precise diagnosis of severity/extent of baseline lesions. We aimed to develop a less endoscopy-related equipment-dependent risk-stratification tool, and assessed whether mild-precursor-lesion patients can be safely exempt from surveillance. In the multicenter communitybased cohort, 75,051 participants receiving baseline endoscopy were enrolled during 2015–2017 and followed-up until 2021. Cumulative incidence rates（CIRs） of GC for precancerous-conditions were calculated by Kaplan-Meier method and compared by Log-rank tests. Mixedeffects Cox regression models were used to detect potential factors for progression towards GC. A risk score was calculated as counts of selected factors. An independent cohort, including 26,586 participants was used for external validation. During a median follow-up of 6.25 years, CIRs of GC were 0.302%, 0.436%, and 4.756% for normal group, non-neoplastic（atrophic gastritis/intestinal metaplasia） and neoplastic lesions（low-grade/high-grade dysplasia）, respectively(Ptrendlimited vegetable consumption, were selected for risk-stratification. High-risk patients（≥3 risk factors） with non-neoplastic lesions showed higher GC risks（adjusted HR=7.73, 95%CI: 4.29–13.92）, and their four-year CIR reached the one-year CIR of neoplastic lesions. Further categorizing non-neoplastic lesions by histological grade, both patients with moderate-to-severe lesions（aHR=3.07, 95%CI: 1.67–5.64） and high-risk patients with mild lesions（aHR=7.29, 95%CI: 3.58–14.86） showed higher risks. Consistent trends were observed in validation cohort. High-risk mild-precursor-lesion patients should receive surveillance within 3–5 years after baseline screening. Our study provides evidence on supplementing current guideline recommendations.
