Targeting PTBP3-Mediated Alternative Splicing of COX11 Induces Cuproptosis for Inhibiting Gastric Cancer Peritoneal Metastasis.

Numerous aberrant splicing events are implicated in tumor progression, yet comprehensive reports on splicing factors and events associated with peritoneal metastasis in gastric cancer (GCPM) are lacking. In this study, PTBP3 is found to be significantly overexpressed in peritoneal metastatic tissues of gastric cancer compared to primary tumor tissues, and higher PTBP3 expression correlates with poorer prognosis. Using gastric cancer cells and patient-derived organoids (PDO), the role of PTBP3 in promoting tumor invasion and proliferation is investigated.

Metabolic responses of microalgal-bacterial granular sludge to enrofloxacin and sulfamethoxazole exposure.

This study examined the removal performance and responses of the microalgal-bacterial granular sludge (MBGS) system to enrofloxacin (ENR), sulfamethoxazole (SMX), and their combination. Results showed that MBGS could achieve 73.2 % and 64.

Impact of sediment microbial fuel cells on the distribution of different forms of phosphorus in lake sediment and water.

The continuous release of phosphorus from sediments by geochemical processes can cause endogenous eutrophication. This study examined the effect of carbon felt-sediment microbial fuel cells (CF-SMFCs) on the release of deposited phosphorus into the overlying water. In the CF-MFC system, the voltage ranged from 27 to 584 mV and the anode electrode potential increased from -130 mV to 202 mV.

Incorporation of Hydroquinone in the Synthesis of BiTiO-TiO Contributes to Higher Efficiency of Hydroquinone Degradation: Preparation, Characterization, and Photocatalytic Mechanism.

In this paper, Bi-doped hydroquinone (HDQ) molecularly imprinted TiO (Bi-HDQ-TiO) with the synthesis of BiTiO-TiO as the main ingredient was developed. Using HDQ as an imprinted molecule, Bi(NO)-5HO was introduced into the synthesis of Bi-HDQ-TiO, which revealed that bismuth oxide was protected by HDQ in the temperature range of 0-450 °C, and during the gradual increase of the temperature up to 550 °C, the HDQ eluted completely, then the surrounding TiO was nucleated by bismuth oxide and bonded with the bismuth oxide, causing all of them to be transformed into BiTiO. The excited electrons of the catalyst could be transported efficiently in various surface interfaces, meanwhile inhibiting the complexation of photogenerated carriers, thereby improving the efficiency of photocatalysis.

A new species of Simon, 1887 from Baiyan Cave in Guizhou Province, China (Araneae, Linyphiidae).

Zhou & Xu, (♂♀) is the first species in the genus to be described from Baiyan Cave in Guizhou Province, China. The new species is similar to Zhu, Chen & Sha, 1987 but differs in structural details of the genital organs, primarily by the presence of a well-developed retrolateral tibial apophysis, a hook-shaped distal end of the radix in the male palp, and the rectangular posterior median plate in the epigyne. The illustration of copulatory organs of (Clerck, 1757) and Zhu, Chen & Sha, 1987 were reproduced here for comparison.

Anomalous Enrichment of As and Hg in Underground Coal Dust: A Case from Xishan Coalfield, Shanxi Province, North China.

Coal dust is an important source of coal workers' pneumoconiosis, which is harmful to the health of underground workers. The coal dust samples were directly collected using a coal dust sampler from four major production positions in the underground coal mine. The particle size distribution, mineralogy, and occurrence of As and Hg in the coal dust samples were investigated.

Experimental Research on Seismic Behavior of Seismic-Damaged Double-Deck Viaduct Frame Pier Strengthened with CFRP and Enveloped Steel.

This paper investigates the seismic behavior of a seismic-damaged double-deck viaduct frame pier (DVFP) strengthened with CFRP and enveloped steel, four strengthened DVFP specimens with different degrees of initial damage were tested under quasi-static cyclic loading. Based on the test results, the hysteretic behavior, the stiffness and strength degradation, crack propagation, and failure mechanism were firstly analyzed. Then, the damage indexes of the tested specimens were calculated with different models to evaluate the seismic strengthening performance.

Experimental Study on Self-Centering Performance of the SMA Fiber Reinforced ECC Composite Beam.

The combination of superelastic shape memory alloy fibers and ECC materials can form a new SMA fiber reinforced ECC composite material (SMAF-ECC) with good self-centering performance. In order to study the self-centering performance of the new composite material, 6 groups of pre-notch beam specimens were made for three-point bending cyclic loading tests, and the failure phenomenon, hysteresis curve, self-centering effect and influencing factors of the specimens were analyzed. The research results show that when the SMA fibers are effectively anchored in the ECC matrix, the SMA fibers can exert the superelastic properties to provide the ECC beams with recoverying force, and realize the crack self-closure and deflection self-recovery function for the beams, with the minimum residual crack width and deflection is only 0.

Evaluation of photodegradation performance by paper microzones.

Currently, the performance evaluation of catalysts usually requires expensive instruments. Hence, it is imperative to develop an alternative, green and sustainable method to investigate the photocatalytic reaction processes. Herein, the variation of degradation performance of different wastewaters with different dosage of P25 TiO was evaluated to verify the reliability of the paper microzones method (PMZs).

Biomagnification and trophic transfer of total mercury and methylmercury in a sub-tropical montane forest food web, southwest China.

Little is known about the bioaccumulation and trophic transfer of total mercury (THg) and methylmercury (MeHg) via food webs in terrestrial ecosystems, especially in subtropical forest ecosystems. In the present study, THg and MeHg were determined as well as the carbon (δC) and nitrogen (δN) isotope composition in samples of soils, plants, invertebrates, and songbird feathers to construct food webs in a remote subtropical montane forest in Mt. Ailao, southwest China and assess the bioaccumulation, biomagnification, and trophic transfer of Hg.

Evaluation of the photocatalytic performance of molecularly imprinted S-TiO by paper microzones.

The paper microzones method (PMZs) is a green chemical method that uses the principle of the three primary colors of red, green and blue (RGB) to detect the water quality of the droplets on white paper. However, this method is rarely used in the performance evaluation of photocatalysts. The paper details the first use of paper microzones utilized in the evaluation of photocatalyst performance.

Silicate improves growth and ion absorption and distribution in aloe vera under salt stress.

Si 2.0 mmol/L in irrigation solution alleviated significantly the inhibition of NaCl stress of 100 or 200 mmol/L to aloe growth. Exogenously applied Si decreased significantly Na(+) and Cl(-) contents, increased K(+) content and K(+)/Na(+) ratio and selectivity ratio of absorption (AS(K, Na)) and of translocation (TS(K, Na)) to K(+) and Na(+) in aloe plant under both NaCl 100 and 200 mmol/L stresses for 30 d.
