DDX18 coordinates nucleolus phase separation and nuclear organization to control the pluripotency of human embryonic stem cells.

Pluripotent stem cells possess a unique nuclear architecture characterized by a larger nucleus and more open chromatin, which underpins their ability to self-renew and differentiate. Here, we show that the nucleolus-specific RNA helicase DDX18 is essential for maintaining the pluripotency of human embryonic stem cells. Using techniques such as Hi-C, DNA/RNA-FISH, and biomolecular condensate analysis, we demonstrate that DDX18 regulates nucleolus phase separation and nuclear organization by interacting with NPM1 in the granular nucleolar component, driven by specific nucleolar RNAs.

HIV risk and influence factors among MSM who had sought sexual partners in core venues: a continuous sentinel surveillance in 2010-2022.

Background: Seeking sexual partners in men who have sex with men (MSM) venues has been regarded as a high-risk behavior for HIV among MSM. Nevertheless, with the implementation of venue-based interventions and the change in the way MSM seek sexual partners, the continued status of MSM venues as the HIV risk factor remains inconclusive. This study endeavors to delve into this ambiguity by examining the MSM sexual contact network (SCN) as a foundation.

Herein, we use surface-enhanced Raman spectroscopy to study the electro-decomposition of ammonia on the Au surface.

Community Assembly Mechanisms of nirK- and nirS-type Denitrifying Bacteria in Sediments of Eutrophic Lake Taihu, China.

Denitrifying bacteria, particularly nirK- and nirS-type, are functionally equivalent and could occupy different niches, but their community assembly mechanisms and responses to environmental heterogeneity are poorly understood in eutrophic lakes. In this study, we investigated the community assembly mechanisms of nirK- and nirS-type denitrifying bacteria and clarified their responses to sediments environmental factors in Lake Taihu, China. The quantitative real-time PCR and Illumina HiSeq-based sequencing revealed that the abundance and composition of two types of denitrifying bacterial communities varied among different sites in the sediments of Lake Taihu.

Intermittent social isolation enhances social investigation but impairs social memory in adult male mice.

Social isolation profoundly impacts motivated behavior and neural plasticity. While the effects of acute and chronic social isolation have been extensively studied, the consequences of intermittent isolation during adulthood, particularly relevant to modern lifestyles, remain poorly understood. This study investigated the impact of intermittent social isolation (ISI) on social behavior and brain activation in adult male mice.

Landscape of somatic mutations and clonal evolution in NUP98-rearranged adult acute myeloid leukaemia.

Acute myeloid leukaemia with NUP98 rearrangement (AML-NUP98) has been previously described in paediatric patients, and the clinical significance in adult AML patients remains largely unexplored. In this study, we identified specific partner fusion genes and examined somatic co-mutations and clonal evolution longitudinally in adult AML-NUP98 patients. Our comprehensive analysis provides an understanding of NUP98 rearrangement and co-mutations influencing clonal evolution and disease progression and offers valuable insights into potential therapeutic strategies.

Sulfonium perchlorate based near-infrared fluorescent probe targeting lysosome for pH imaging in living cells and tumor-bearing mice.

Due to the accumulation of lactate and other acidic metabolites from insufficient blood supply and hypoxia, the acidic microenvironment of tumors not only accelerates tumor growth and spread but may also affect immune cell function, thereby aiding tumor development. Therefore, real-time monitoring of pH fluctuations in intracellular and living systems provides crucial insights into physiological and pathological processes. This research introduced a novel NIR fluorescent probe, termed SOH, for pH imaging in living cells and tumor-bearing mice.

Causal effects of the RANK-RANKL-OPG system and scoliosis: A bidirectional 2-sample Mendelian randomization study.

Epidemiological studies and a recent Mendelian randomization (MR) study have identified an association between low bone mass and an increased risk of scoliosis. Previous research suggests that bone loss in patients with scoliosis may be related to the RANK-RANKL-OPG system. This study is to investigate whether a causal relationship exists between the RANK-RANKL-OPG system and the development of scoliosis.

π-HuB: the proteomic navigator of the human body.

The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

Neuroligin 1 Regulates Autistic-Like Repetitive Behavior through Modulating the Activity of Striatal D2 Receptor-Expressing Medium Spiny Neurons.

Restricted and repetitive behavior (RRB) is a primary symptom of autism spectrum disorder (ASD), which poses a significant risk to individuals' health and is becoming increasingly prevalent. However, the specific cellular and neural circuit mechanisms underlying the generation of RRB remain unclear. In this study, it is reported that the absence of the ASD-related protein Neuroligin 1 (NLGN1) in dopamine receptor D2-expressing medium spiny neurons (D2-MSNs) in the dorsal striatum is associated with the duration and frequency of self-grooming and digging behaviors.

Lipid-related radiomics of low-echo carotid plaques is associated with diabetic stroke and non-diabetic coronary heart disease.

Carotid plaque radiomics-included models have increased the predictive capacity of cardiovascular risk, but the radiomic features of these models were inconsistent in previous studies. Lipids could be used to select the most important radiomic feature. A retrospective case‒control study was performed in 153 diabetic and 76 non-diabetic patients with carotid plaque detected by ultrasound.

Multi-Intelligent Reflecting Surfaces and Artificial Noise-Assisted Cell-Free Massive MIMO Against Simultaneous Jamming and Eavesdropping.

In a cell-free massive multiple-input multiple-output (MIMO) system without cells, it is assumed that there are smart jammers and disrupters (SJDs) that attempt to interfere with and eavesdrop on the downlink communications of legitimate users. A secure transmission scheme based on multiple intelligent reflecting surfaces (IRSs) and artificial noise (AN) is proposed. First, an access point (AP) selection strategy based on user location information is designed, which aims to determine the set of APs serving users.

Exacerbated hepatotoxicity in in vivo and in vitro non-alcoholic fatty liver models by biomineralized copper sulfide nanoparticles.

Copper sulfide nanoparticles (NPs) synthesized through biomineralization have significant commercial potential as photothermal agents, while the safety evaluation of these NPs, especially for patients with non-alcoholic fatty liver (NAFL), remains insufficient. To explore the differential hepatotoxicity of copper sulfide NPs in NAFL conditions, we synthesized large-sized (LNPs, 15.1 nm) and small-sized (SNPs, 3.

A tumor-pH-responsive phthalocyanine as activatable type I photosensitizer for improved photodynamic immunotherapy.

The development of a simple drug formulation capable of achieving both activatable type I photoreaction and tumor-responsive release of immunomodulator is crucial for advancing photodynamic immunotherapy (PDIT). Herein, we present a nanostructured photosensitizer (NP5) that is activated by the acidic tumor microenvironment to produce type I reactive oxygen species (ROS) under light irradiation and release the immunomodulator demethylcantharidin (DMC) for PDIT. The NP5 is formed by self-assembly of a versatile phthalocyanine molecule which is composed of DMC and phthalocyanine linked via a pH-responsive amide bond.
