Prevalence of malnutrition among adult inpatients in China: a nationwide cross-sectional study.

Malnutrition substantially contributes to adverse clinical outcomes. However, no national survey has been conducted to characterize its epidemiology in hospital settings in China. We conducted the China Nutrition Fundamental Data 2020 project among a multistage stratified cluster sample of adult inpatients from 291 study sites across 30 provinces, autonomous regions and municipalities (except for Hong Kong, Macao, Taiwan Province, and the Xizang Autonomous Region, please see MATERIALS AND METHODS for details of the causes) of China to generate reliable data on the prevalence of malnutrition and explore the associated risk factors.

Pan-cancer analysis shows that TNFSF4 is a potential prognostic and immunotherapeutic biomarker for multiple cancer types including liver cancer.

Background: As a member of the tumor necrosis factor (TNF) superfamily, tumor necrosis factor superfamily member 4 (TNFSF4) is expressed on antigen-presenting cells and activated T cells by binding to its receptor TNFRSF4. However, tumorigenicity of TNFSF4 has not been studied in pan-cancer. Therefore, comprehensive bioinformatics analysis of pan-cancer was performed to determine the mechanisms through which TNFSF4 regulates tumorigenesis.

Correlations of the expression of Cx43, SCF, p-cyclin E1 (Ser73), p-cyclin E1 (Thr77) and p-cyclin E1 (Thr395) in colon cancer tissues.

Background: Previous cellular studies have demonstrated that elevated expression of Cx43 promotes the degradation of cyclin E1 and inhibits cell proliferation through ubiquitination. Conversely, reduced expression results in a loss of this capacity to facilitate cyclin E degradation. The ubiquitination and degradation of cyclin E1 may be associated with phosphorylation at specific sites on the protein, with Cx43 potentially enhancing this process by facilitating the phosphorylation of these critical residues

Aim: To investigate the correlation between expression of Cx43, SKP1/Cullin1/F-box (SCF), p-cyclin E1 (ser73, thr77, thr395) and clinicopathological indexes in colon cancer.

LC-MS/MS Analyzing Praziquantel and 4-Hydroxypraziquantel Enantiomers in Black Goat Plasma and Mechanism of Stereoselective Pharmacokinetics.

Praziquantel (PZQ) is the most effective treatment for schistosomiasis, commonly administered as a racemic mixture of the two enantiomers. Despite many reports on the pharmacokinetics of PZQ, the stereoselective pharmacokinetics of PZQ and its major metabolite 4-hydroxypraziquantel (4-OH-PZQ) remain poorly understood in goats. In this study, the chiral LC-MS/MS method was further optimized for separating and quantifying PZQ, trans-4-OH-PZQ, and cis-4-OH-PZQ and their enantiomers and then applied for the molecular pharmacokinetics of three analytes in black goat plasma.

In this paper, the short-range ordering structures of Ga melts has been investigated using the Wulff cluster model (WCM). The structures with a Wulff shape outside and crystal symmetry inside have been derived as the equivalent system to describe the short-range-order (SRO) distribution of the Ga melts. It is observed that the simulated HTXRD patterns of the Ga WCM are in excellent agreement with the experimental data at various temperatures (523 K, 623 K, and 723 K).

Radiative Warming Glass for High-Latitude Cold Regions.

Traditional window glazing, with inherently adverse energy-efficient optical properties, leads to colossal energy losses. Energy-saving glass requires a customized optical design for different climate zones. Compared with the widely researched radiative cooling technology which is preferable to be used in low-altitude hot regions; conversely in high-latitude cold regions, high solar transmittance (T) and low mid-infrared thermal emissivity (ε) are the key characteristics of high-performance radiative warming window glass, while the current low-emissivity (low-e) glass is far from ideal.

AENK ameliorates cognitive impairment and prevents Tau hyperphosphorylation through inhibiting AEP-mediated cleavage of SET in rats with ischemic stroke.

Brain damage induced by ischemia promotes the development of cognitive dysfunction, thus increasing the risk of dementia such as Alzheimer's disease (AD). Studies indicate that cellular acidification-triggered activation of asparagine endopeptidase (AEP) plays a key role in ischemic brain injury, through multiple molecular pathways, including cleavage of its substrates such as SET (inhibitor 2 of PP2A, I ) and Tau. However, whether direct targeting AEP can effectively prevent post-stroke cognitive impairment (PSCI) remains unanswered.

Enhanced electro-catalysis for methanol oxidation reaction performance by edge defects of ordered mesoporous carbon.

Heteroatom-doped carbon materials are widely used to improve the electrocatalytic oxidation of methanol; however, the underlying mechanisms driving this enhancement remain poorly understood. A major challenge lies in developing non-doped carbon supports with tunable intrinsic defect types tailored for metal-based catalysts. In this study, we synthesize a series of ordered mesoporous carbon (OMC) supports with adjustable edge defect densities by varying roasting temperatures and employing a zinc (Zn) evaporation strategy to systematically investigate the impact of edge defects on methanol oxidation reaction (MOR) performance.

Chinese expert consensus on sequential surgery following conversion therapy based on combination of immune checkpoint inhibitors and antiangiogenic targeted drugs for advanced hepatocellular carcinoma (2024 edition).

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits.

Effects of synbiotics surpass probiotics alone in improving type 2 diabetes mellitus: A randomized, double-blind, placebo-controlled trial.

This study aimed to evaluate the effects of Bifidobacterium animalis subsp. lactis MN-Gup (MN-Gup) and a synbiotic mixture of MN-Gup and galactooligosaccharide (MN-Gup-GOS) on glycemic control in T2DM patients and explore possible mechanisms.

Extraction of short-chain fatty acid ethyl Ester in Baijiu using covalent organic framework-based magnetic nanoparticles: Theoretical screening and experimental validation.

Short-chain fatty acid ethyl esters (SFAEEs) are critical aroma compounds in Baijiu, and their wider concentration range can lead to differences in the quality grade of Baijiu. Efficiently designing an SFAEEs adsorbent before instrument analysis remains challenging. In this work, nine functionalized covalent organic frameworks (COFs) with different postmodification groups were designed for targeting SFAEEs.

Non-image-forming photoreceptors improve visual orientation selectivity and image perception.

It has long been a decades-old dogma that image perception is mediated solely by rods and cones, while intrinsically photosensitive retinal ganglion cells (ipRGCs) are responsible only for non-image-forming vision, such as circadian photoentrainment and pupillary light reflexes. Surprisingly, we discovered that ipRGC activation enhances the orientation selectivity of layer 2/3 neurons in the primary visual cortex (V1) of mice by both increasing preferred-orientation responses and narrowing tuning bandwidth. Mechanistically, we found that the tuning properties of V1 excitatory and inhibitory neurons are differentially influenced by ipRGC activation, leading to a reshaping of the excitatory/inhibitory balance that enhances visual cortical orientation selectivity.
