Hepatitis B virus (HBV) capsid assembly modulators (CAMs) represent a promising therapeutic approach in the treatment of chronic HBV infection. In the quest for effective therapeutics against chronic Hepatitis B virus (HBV) infection, we employed a novel binding site occupancy strategy to develop novel 2-cyclopropyl-thioureidobenzamide (CP-TBA) derivatives as potent HBV CAMs. Our diversity modification approach led to the identification of compound 17e, which demonstrated remarkable anti-HBV activity with an EC of 0.

Methods: 283 pregnant women with COVID-19 were included in the prospective observational cohort study and divided into five groups based on infection stage. Antibody levels were measured in plasma, umbilical cord blood, and breast milk, and combined with clinical data and 6-month follow-up results.
: Elevated estrogen has been found to contribute to the pathological development of endometrial cancer (EC), potentially through alterations in the tumor inflammatory immune microenvironment. However, the exact mechanisms underlying this process remain unclear. : Bioinformatics was used to identify differentially expressed genes, analyze pathway enrichment, and assess their correlation with immune cell infiltration.
View Article and Find Full Text PDFTransition metal phosphides (TMPs) have emerged as promising anode materials for lithium-ion batteries (LIBs). However, their poor intrinsic conductivity and significant volume changes result in slow redox kinetics and structural collapse during cycling, which hinder their practical application. Here, a hierarchical hybrid anode is synthesized by evenly dispersing NiP particles with N-doped carbon encapsulation on Co(OH) nanosheets (Co(OH)/NiP@N-C).

The film successfully mimics the asymmetric, bionic, barbed structure of a duck feather, offering outstanding hydrophobicity and moisture vapor resistance characteristics. Moreover, the bionic film demonstrated good mechanical strength, film-forming ability and biodegradability.

Despite the large body of research investigating the effects of high-intensity interval training (HIIT) on cognitive performance, reports of its effectiveness are inconsistent and it is difficult to determine what factors moderate these effects. The purpose of this study was to conduct a meta-analysis of existing randomised controlled trials investigating the effects of HIIT on various domains of cognitive performance, and to further examine the intervention cycle and age-related moderating effects.

Empathy plays a crucial role in children's social-emotional development. There is an increasing trend in recent studies to recognize empathy as a multi-dimensional construct, consisting of three distinct hierarchical levels: emotion contagion, attention to others' feelings and prosocial behaviors (Hoffman, Motiv Emot, 14(2), 151-172, 1990). The present study is amongst the first to use a longitudinal approach to examine the development trajectories of the distinct empathic levels, based on a sample of Chinese preschoolers aged 2 to 6 years, half of the sample being deaf or hard-of-hearing (DHH).
View Article and Find Full Text PDFTransition metal sulfides (TMSs) are considered as one of the most promising anode materials for lithium-ion batteries (LIBs) in virtue of their high theoretical specific capacity, low cost and environmental friendliness. However, the intrinsic poor electron/ion transport, large volume change and the shuttle effect of polysulfides hinder their achievement of superb rate capability and cycle performance. Compared with the monometallic sulfides, bimetallic sulfides have superior electron transport capability and higher electrochemical activity.

Levodopa, a key component of dopamine replacement therapy, effectively enhances dopaminergic activity. However, it encounters obstacles from peripheral decarboxylase, hindering its passage through the BBB.

This study explores the longitudinal causal relationship between self-perceptions of aging and frailty and examines whether subjective cognitive decline mediated the associations.
Methods: The Brief-Aging Perceptions Questionnaire(B-APQ), the Frailty Phenotype Assessment Scale, and the Subjective Cognitive Decline Questionnaire were used to survey 619 community-dwelling older adults in Xinxiang, Henan, China, from March to October 2021 and from March to October 2023, respectively.
The hydration properties of starch were examined in relation to mass transfer and the characteristics of deep-frying batter. With extended deep-frying, the oil content in all samples increased, while the moisture content exhibited an inverse trend. Analyses of zeta potential, disulfide bonds, secondary structure, particle size of the proteins, thermal properties, and water status indicated that prolonged deep-frying time facilitated protein aggregation and led to a decrease in both gelatinization enthalpy (ΔH) and the percentage of bound water.

However, their detailed features and regulatory mechanisms of LUC7L2 in the development of human liver cancer have not been well characterized.
Results: Herein, our results demonstrate that LUC7L2 promotes the proliferation of liver cancer cells in vitro and xenograft transplantation in vivo.
Purpose: Ferroptosis is a regulated form of cell death characterized by iron-dependent accumulation of associated lipid peroxides (LPO), which can induce cell death when a certain level is reached. However, the extremely complex tumor microenvironment (TME) has the characteristics of antioxidant, even if it induces ferroptosis of tumor cells, its killing effect on tumor cells is still very limited. To solve this problem, we constructed a novel nanomaterials (GOx/EC@FeO@CCM).

The insertion of small drug molecules into DNA can change its electrical properties, thereby controlling the probability of its electrical transmission. This characteristic has enabled its widespread application in molecular electronics. However, the current understanding of the intercalation properties and electronic transmission mechanisms is still not deep enough, which severely restricts its practical application.
