Horizontal Transport in TiCT MXene for Highly Efficient Osmotic Energy Conversion from Saline-Alkali Environments.

Osmotic energy from the ocean has been thoroughly studied, but that from saline-alkali lakes is constrained by the ion-exchange membranes due to the trade-off between permeability and selectivity, stemming from the unfavorable structure of nanoconfined channels, pH tolerance, and chemical stability of the membranes. Inspired by the rapid water transport in xylem conduit structures, we propose a horizontal transport MXene (H-MXene) with ionic sequential transport nanochannels, designed to endure extreme saline-alkali conditions while enhancing ion selectivity and permeability. The H-MXene demonstrates superior ion conductivity of 20.

Bowel function, quality of life, and mental health of patients with high-grade intraepithelial neoplasia or T1 colorectal cancer after organ-preserving versus organ-resection surgeries: a cross-sectional study at a Chinese tertiary care center.

Background: This study aimed to determine the postoperative intestinal functioning, quality of life (QoL), and psychological well-being of patients treated either with organ-preserving surgery (OPS) or organ-resection surgery (ORS) for high-grade intraepithelial neoplasia (HIN) or T1 colorectal cancer (CRC).

Methods: This cross-sectional study was conducted at a single tertiary care center. In total, 175 eligible individuals with T1 CRC or HIN were divided into the OPS (n = 103) or ORS (n = 72) group based on whether the relevant segment of the intestine was preserved or resected.

Incorporating glacier processes into hydrological simulations in the headwaters of the Yangtze and yellow Rivers.

Contemporary hydrological models often oversimplify or neglect the effects of glacier ablation on watershed hydrological processes, leading to inaccurate simulations. To address this issue, we introduce a glacier ablation module that incorporates glacier ablation, sublimation, meltwater refreezing, and snow accumulation, integrated with the fully distributed hydrological model ESSI-3, forming the Glacier-ESSI-3 model. Application of the Glacier-ESSI-3 model in the headwaters of the Yangtze River (HYaR) and Yellow River (HYeR) demonstrates superior accuracy compared to the ESSI-3 model, effectively capturing the impact of glacier ablation on hydrological dynamics.

UBTD1 is a potential prognostic biomarker in colorectal cancer.

Colorectal cancer (CRC) is a complex malignancy with poorly understood molecular mechanisms, necessitating the identification of genetic markers. Although Ubiquitin domain-containing protein 1 (UBTD1) has received significant attention in the study of human cancers, its specific role in CRC is yet to be fully clarified. This study sought to examine how UBTD1 expression was associated with various clinical and pathological characteristics of CRC, and to determine its prognostic significance and biological function, utilizing data from clinical samples and large-scale databases.
