Purpose: This study aims to explore the mechanisms of daphnetin to reduce H.

Risk factors and nomogram for the prediction of intracranial hemorrhage in very preterm infants.

Aims: This study aims to identify important risk factors for intracranial hemorrhage (ICH) in very preterm infants at our institution and develop a predictive nomogram for early detection of ICH.

Methods: We retrospectively analyzed neonates with a gestational age (GA) under 32 weeks, admitted to the neonatal intensive care unit from March 2022 to July 2023. Infants were categorized into two groups based on ultrasound findings and assessed for thirteen variables including gender, GA, birth weight (BW), acidosis, among others.

Dental stem cell dynamics in periodontal ligament regeneration: from mechanism to application.

Periodontitis, a globally prevalent chronic inflammatory disease is characterized by the progressive degradation of tooth-supporting structures, particularly the periodontal ligament (PDL), which can eventually result in tooth loss. Despite the various clinical interventions available, most focus on symptomatic relief and lack substantial evidence of supporting the functional regeneration of the PDL. Dental stem cells (DSCs), with their homology and mesenchymal stem cell (MSC) properties, have gained significant attention as a potential avenue for PDL regeneration.

Dissecting the cell microenvironment of ovarian endometrioma through single-cell RNA sequencing.

Ovarian endometrioma (OE), also known as "chocolate cysts," is a cystic mass that develops in the ovaries due to endometriosis and is a common gynecological condition characterized by the growth of endometrial tissue outside the uterus, leading to symptoms such as dysmenorrhea, pelvic pain, and infertility. However, the precise molecular and cellular mechanisms driving this pathophysiology remain largely unknown, posing challenges for diagnosis and treatment. Here, we employed integrated single-cell transcriptomic profiling of over 52,000 individual cells from endometrial tissues of OE patients and healthy donors and identified twelve major cell populations.

Status of Horizontal Violence, Level of Psychological Empowerment, and Their Correlation Among Obstetric Nurses: A Cross-Sectional Survey.

Background: China's maternity policy has led to an increase in work pressure, which has prompted horizontal violence among obstetric nurses. To understand this phenomenon better, we attempted to identify the factors that influence horizontal violence as well as the level of psychological empowerment among obstetric nurses.

Methods: This cross-sectional survey was conducted among 522 obstetric nurses from December 2022 to February 2023.

Inhibitory Effect of CMU-Pb-L5 In a Subcutaneous Transplanted Tumor Model of Colorectal Cancer.

() is a prevalent probiotic strain within the genus, which has robust intestinal colonization capabilities. Previous studies have demonstrated the anticancer properties of both and . However, the mechanisms underlying its anticancer activity remain unclear.

Dexmedetomidine Alleviates the Long-Term Neurodevelopmental Toxicity Induced by Sevoflurane in the Developing Brain.

Introduction: Sevoflurane is an extensively used anesthetic for pediatric patients; however, numerous studies showed that sevoflurane (SEVO) may cause long-term neurodevelopmental toxicity. Dexmedetomidine (DEX) has been shown to be protective against SEVO-induced neurotoxicity, but the mechanism remains unclear. The effects and mechanisms of different DEX administration routes on SEVO-induced neurotoxicity and long-term cognitive defects were determined and further investigated the role of sex in these processes.

Exosomal miR-494 Regulates the Biological Behavior of Trophoblasts by Targeting mTOR in Unexplained Recurrent Spontaneous Abortion.

Recurrent spontaneous abortion (RSA) is a pregnancy disorder, and trophoblasts are involved in its complex pathogenesis. This study aimed to identify the functional role of exosomal miR-494 in promoting the development of unexplained RSA (uRSA). 15 uRSA tissues and 15 healthy controls were collected to compare the exosomal miR-494 expression.

[Thumbtack needle at front- points for abnormal behavior in children with autism spectrum disorders].

Objective: To compare the clinical effect of thumbtack needle at front- points combined with conventional rehabilitation training and simple conventional rehabilitation training in the treatment of autism spectrum disorders (ASD).

Methods: A total of 40 children with ASD were randomly divided into a combination group (20 cases, 3 cases dropped out) and a conventional rehabilitation group (20 cases, 3 cases dropped out). Conventional rehabilitation training i.

Diverse BCR usage and T cell activation induced by different COVID-19 sequential vaccinations.

Unlabelled: Limited knowledge is available on the differences in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) specific antibody breadth and T cell differentiation among different COVID-19 sequential vaccination strategies. In this study, we compared the immunogenicity of the third different dose of COVID-19 vaccines, such as mRNA (I-I-M), adenoviral vector (I-I-A), and recombinant protein (I-I-R) vaccines, in terms of the magnitude and breadth of antibody response and differentiation of SARS-CoV-2-specific T and B cells. These studies were performed in the same clinical trial, and the samples were assessed in the same laboratory.

AOPPs induces EMT and fibrosis by activating oxidative stress through ERK/p38 MAPK signaling pathway in endometriosis.

Epithelial-mesenchymal transition (EMT) is known to play a crucial role in the development of endometriosis (EMs). However, the exact mechanisms involved in EMT regulation in EMs are not well understood. In this study, we performed comprehensive research using clinical samples, single-cell sequencing, and in vivo/in vitro models to investigate the effects of advanced oxidation protein products (AOPPs) on EMT and the underlying mechanisms in EMs.

Oxygen extraction fraction change in M1-M6 brain regions of patients with unilateral or bilateral middle cerebral artery occlusion.

Cerebral blood flow (CBF) and oxygen extraction fraction (OEF) can be measured using arterial spin labeling (ASL) and quantitative susceptibility mapping (QSM) sequences, respectively. ASL and QSM sequences were performed on 13 healthy participants and 46 patients with unilateral or bilateral Middle cerebral artery (MCA) occlusion. M1-M3 and M4-M6 correspond to anterior, lateral, and posterior MCA territories within the insular ribbon and centrum semiovale, respectively.

Uncovering the Role of Anoikis-Related Genes in Modulating Immune Infiltration and Pathogenesis of Diabetic Kidney Disease.

Background: Diabetic kidney disease (DKD) is an intricate complication of diabetes with limited treatment options. Anoikis, a programmed cell death activated by loss of cell anchorage to the extracellular matrix, participated in various physiological and pathological processes. Our study aimed to elucidate the role of anoikis-related genes in DKD pathogenesis.

Tri (2-Ethylhexyl) phosphate (TEHP), widely used as a fire retardant and plasticizer, has been commonly found in the environment. Its potential health-related risks, especially reproductive toxicity, have aroused concern. However, the potential cellular mechanisms remain unexplored.

TMEM176B Promotes EMT via FGFR/JNK Signalling in Development and Tumourigenesis of Lung Adenocarcinoma.

Lung cancer, the leading cause of cancer-related incidence and mortality worldwide, is characterised by high invasiveness and poor prognosis. Novel therapeutic targets are required, especially for patients with inoperable metastatic disease requiring systemic therapies to improve patients' welfare. Recently, studies indicated that TMEM176B is a positive regulator in breast and gastric cancers, and it could be a potential target for treatment.
