How do cumulative family risks influence the trajectory of problematic social media use among Chinese adolescents: A three-year longitudinal study.

Background And Aims: Problematic social media use (PSMU) is a concerning public health issue among adolescents. Existing literature has paid attention to the role of singular family risk on PSMU, but how cumulative family risks affect the trajectory of PSMU needs to be further explored.

Methods: The current study employed a five-wave longitudinal design that lasted for three years (each time interval: 6, 6, 12, and 12 months) to reveal the longitudinal mechanism between cumulative family risks and the trajectory of PSMU, examining the mediating roles of escape and relationship motivations.

Apolipoprotein B100 acts as a tumor suppressor in ovarian cancer via lipid/ER stress axis-induced blockade of autophagy.

Ovarian cancer presents a significant treatment challenge due to its insidious nature and high malignancy. As autophagy is a vital cellular process for maintaining homeostasis, targeting the autophagic pathway has emerged as an avenue for cancer therapy. In the present study, we identify apolipoprotein B100 (ApoB100), a key modulator of lipid metabolism, as a potential prognostic biomarker of ovarian cancer.

FunlncModel: integrating multi-omic features from upstream and downstream regulatory networks into a machine learning framework to identify functional lncRNAs.

Accumulating evidence indicates that long noncoding RNAs (lncRNAs) play important roles in molecular and cellular biology. Although many algorithms have been developed to reveal their associations with complex diseases by using downstream targets, the upstream (epi)genetic regulatory information has not been sufficiently leveraged to predict the function of lncRNAs in various biological processes. Therefore, we present FunlncModel, a machine learning-based interpretable computational framework, which aims to screen out functional lncRNAs by integrating a large number of (epi)genetic features and functional genomic features from their upstream/downstream multi-omic regulatory networks.

The Longitudinal Association Between Negative Life Events and Problematic Social Media Use Among Chinese College Students: The Mediating Role of FoMO and the Moderating Role of Positive Parenting.

Negative life events are one of the risk factors leading to problematic social media use (PSMU) among Chinese college students, but the underlying mechanism between them remains unclear. Based on compensatory internet use theory, a moderated mediation model was examined, with two dimensions of fear of missing out (FoMO) considered as parallel mediators and positive parenting as a moderator. A total of 525 college students (57.

SpatialRef: a reference of spatial omics with known spot annotation.

Spatial omics technologies have enabled the creation of intricate spatial maps that capture molecular features and tissue morphology, providing valuable insights into the spatial associations and functional organization of tissues. Accurate annotation of spot or domain types is essential for downstream spatial omics analyses, but this remains challenging. Therefore, this study aimed to develop a manually curated spatial omics database (SpatialRef, https://bio.

Resveratrol activates MAPK/ERK pathway to regulate oestrogen metabolism in type I endometrial cancer.

Objective: Endometrial cancer (EC) is an oestrogen-dependent tumour, the occurrence of which is closely related to an imbalance of oestrogen homeostasis. Our previous studies explored the effects of Resveratrol(Res) on oestrogen metabolism. However, systematic research on the exact mechanism of action of Res is still lacking.

Palladium-Catalyzed Dearomative Heck/Suzuki Coupling of C2-Deuterated or C2-Nonsubstituted Indoles.

A palladium-catalyzed dearomative diarylation of C2-deuterated or C2-nonsubstituted indoles through domino Heck/Suzuki coupling is established. Relying on electron-deficient phosphite ligand, side reactions including intermolecular Suzuki coupling and intramolecular C-D/H arylation are inhibited and a wide range of 2,3-diarylated indolines bearing vicinal tertiary stereocenters including deuterated ones are afforded in moderate to excellent yields (up to 94%) and excellent diastereoselectivities (>20:1). The catalyst loading can be lowered to 0.

Mesenteric cystic lymphatic malformation: a rare case report and review of the literature.

Background: Mesenteric cystic lymphatic malformation (LM) is a rare congenital benign malformation in adults, and its location in the mesentery of the sigmoid colon is even rarer.

Case Description: We describe a rare case of LM of the mesentery in a 49-year-old woman. The patient was inadvertently identified during a physical examination 1 month earlier.

scATAC-Ref: a reference of scATAC-seq with known cell labels in multiple species.

Chromatin accessibility profiles at single cell resolution can reveal cell type-specific regulatory programs, help dissect highly specialized cell functions and trace cell origin and evolution. Accurate cell type assignment is critical for effectively gaining biological and pathological insights, but is difficult in scATAC-seq. Hence, by extensively reviewing the literature, we designed scATAC-Ref (https://bio.

An Asynchronous Concerted Mechanism and Its Origin in Lewis Acid-Mediated Carbonyl-Olefin [2+2] Cycloaddition.

The concerted mechanism of thermal BBr -mediated [2+2] carbonyl-olefin cycloaddition is intriguing considering the conflict against the Woodward-Hoffmann rule. In this work, we report a mechanistic study of the titled reaction using density functional theory calculations. The concerted [2+2] cycloaddition mechanism is operative even for the truncated model system of 2-methyl-2-butene and butanone.

Syntheses of Bufospirostenin A and Ophiopogonol A by a Conformation-Controlled Transannular Prins Cyclization.

Controlling the conformation of medium-sized rings is challenging because of their flexibility and ring strain effects. Herein, we report non-Curtin-Hammett conditions for the precise control of the conformation of cyclodecenones to effect the first -selective transannular Prins cyclization, which enabled concise syntheses of the 5(10→1)-steroids bufospirostenin A and ophiopogonol A in only seven steps from inexpensive starting materials. Computational results indicated that the key cyclization was kinetically controlled and proceeded via either a Prins pathway or a carbonyl-ene pathway, depending on the reaction conditions.
