A longitudinal network of psychotic-like experiences, depressive and anxiety symptoms, and adverse life events: a cohort study of 3,358 college students.

Aims: Psychotic-like experiences (PLEs), especially for persistent PLEs, are highly predictive of subsequent mental health problems. Hence, it is crucial to explore the psychopathological associations underlying the occurrence and persistence of PLEs. This study aimed to explore the above issues through a longitudinal dynamic network approach among PLEs and psychological and psychosocial factors.

Distinct trajectories of psychotic-like experiences and their associations with violent behavior among 3539 young adults: A 3-year prospective cohort study.

Background: Violence perpetration may be linked to psychotic-like experiences (PLEs), but relevant research is limited, especially in general population. Therefore, we aimed to identify trajectories of PLEs and examine whether specific trajectories were related to violent behavior in a 3-year cohort study.

Methods: We developed a prospective cohort study and collected data in 2020 (T0), 2021 (T1), and 2022 (T2) in Guangzhou, China.

From light into shadow: comparative plastomes in Petrocosmea and implications for low light adaptation.

Background: Plastids originated from an ancient endosymbiotic event and evolved into the photosynthetic organelles in plant cells. They absorb light energy and carbon dioxide, converting them into chemical energy and oxygen, which are crucial for plant development and adaptation. However, little is known about the plastid genome to light adaptation.

Characteristics and factors associated with psychotic-like experiences in remission: a cross-sectional study of 4208 college students in China.

Objectives: Previous research has extensively explored the factors associated with psychotic-like experiences (PLEs). However, the characteristics and associated factors of remitted PLEs, which refer to the absence of current PLEs following previous PLEs, remain unclear. Therefore, this study aims to describe the characteristics of adolescents who reported remitted PLEs.

"NO" controversy?: A controversial role in insulin signaling of diabetic encephalopathy.

Insulin, a critical hormone in the human body, exerts its effects by binding to insulin receptors and regulating various cellular processes. While nitric oxide (NO) plays an important role in insulin secretion and acts as a mediator in the signal transduction pathway between upstream molecules and downstream effectors, holds a significant position in the downstream signal network of insulin. Researches have shown that the insulin-NO system exhibits a dual regulatory effect within the central nervous system, which is crucial in the regulation of diabetic encephalopathy (DE).

A Janus, robust, biodegradable bacterial cellulose/TiCTx MXene bilayer membranes for guided bone regeneration.

Guided bone regeneration (GBR) stands as an essential modality for craniomaxillofacial bone defect repair, yet challenges like mechanical weakness, inappropriate degradability, limited bioactivity, and intricate manufacturing of GBR membranes hindered the clinical efficacy. Herein, we developed a Janus bacterial cellulose(BC)/MXene membrane through a facile vacuum filtration and etching strategy. This Janus membrane displayed an asymmetric bilayer structure with interfacial compatibility, where the dense layer impeded cell invasion and the porous layer maintained stable space for osteogenesis.

Ultra-Hydrophobic Gauze Driving Super-Haemostasis.

Controlling bleeding by applying pressing cotton gauze is the most facile treatment in prehospital emergencies. However, the wettable nature of cotton fibers leads to unnecessary blood loss due to excessive blood absorption, inseparable adhesion-induced pain, and pliable to infection. Here, a kind of ultra-hydrophobic haemostatic anti-adhesive gauze whose surface is loaded with polydimethylsiloxane (PDMS) and hydrophobic-modified cellulose nanocrystals (CNCs), achieving a water contact angle of ≈160° is developed.

Professional characteristics, numbers, distribution and training of China's mental health workforce from 2000 to 2020: a scoping review.

Over the last 20 years, the numbers, types, distribution, and qualifications of mental health professionals in China have changed dramatically. However, there has been no systematic attempt to collect information about this transformation in the human resources available to provide mental health services-information that needs to be regularly updated to improve the country's coordination of these services. This scoping review compiles current details about China's mental health workforce and identifies critical gaps in available research and reporting.

Bioorthogonal labeling and profiling of N6-isopentenyladenosine (i6A) modified RNA.

TMEM16A deficiency in alveolar type 2 epithelial cells protected against endoplasmic reticulum stress-induced ferroptosis during acute lung injury.

Transmembrane protein 16A (TMEM16A) is one of the members of the ten-member family of "transmembrane protein 16", playing critical roles in infection and solid organ injury. Acute lung injury (ALI) is a devastating disease which could be triggered by sepsis, trauma, and ischemia reperfusion. However, molecular mechanisms contributing to ALI are poorly understood at presently.

Paxillin/HDAC6 regulates microtubule acetylation to promote directional migration of keratinocytes driven by electric fields.

Endogenous electric fields (EFs) have been demonstrated to facilitate wound healing by directing the migration of epidermal cells. Despite the identification of numerous molecules and signaling pathways that are crucial for the directional migration of keratinocytes under EFs, the underlying molecular mechanisms remain undefined. Previous studies have indicated that microtubule (MT) acetylation is linked to cell migration, while Paxillin exerts a significant influence on cell motility.

A TiC MXene-integrated near-infrared-responsive multifunctional porous scaffold for infected bone defect repair.

Infected bone defect repair has long been a major challenge in orthopedic surgery. Apart from bacterial contamination, excessive generation of reactive oxygen species (ROS), and lack of osteogenesis ability also threaten the defect repair process. However, few strategies have been proposed to address these issues simultaneously.

The complete and fully-phased diploid genome of a male Han Chinese.

Since the release of the complete human genome, the priority of human genomic study has now been shifting towards closing gaps in ethnic diversity. Here, we present a fully phased and well-annotated diploid human genome from a Han Chinese male individual (CN1), in which the assemblies of both haploids achieve the telomere-to-telomere (T2T) level. Comparison of this diploid genome with the CHM13 haploid T2T genome revealed significant variations in the centromere.

Degradation of Rat Sarcoma Proteins Targeting the Post-Translational Prenyl Modifications via Cascade Azidation/Fluorination and Click Reaction.

Development of Nitroso-Based Probes for Labeling and Regulation of RAS Proteins in Cancer Cells via Sequential Ene-Ligation and Oxime Condensation.

Prenyl functionalities have been widely discovered in natural products, nucleic acids, and proteins with significant biological roles in both healthy and diseased cells. In this work, we develop a series of new nitroso-based probes for the labeling, enrichment, and regulation of prenylated RAS protein, which is highly associated with ∼20% of human cancers and used to be regarded as an "undruggable" target via a sequential ene-ligation and oxime condensation (SELOC) process. We found that these nitroso species can rapidly react with prenyl-containing molecules through ene-ligation and install a molecular tag for functional applications under physiological conditions.
