Background: Prolyl-4-hydroxylase-A2 (P4HA2) is a pivotal enzyme involved in the regulation of tumorigenesis and progression. However, the precise biological roles and potential functions of P4HA2 in papillary thyroid cancer (PTC) remain poorly elucidated.
Methods: Gain-of-function and loss-of-function approaches were employed to investigate the underlying biological effects of P4HA2 on PTC cell proliferation and metastasis both in vitro and in vivo.
Objective: To investigate the benefit of preimplantation genetic testing for aneuploidy (PGT-A) in recurrent implantation failure (RIF).
Design: Secondary analysis of a multicentre, randomised, double-blind, placebo-controlled clinical trial.
Setting: Eight academic fertility centres in China, 2018-2020.
Introduction And Objectives: Liver stiffness measurement (LSM) by two-dimensional shear-wave elastography (2D SWE) is a well-established method for assessing hepatic fibrosis. Diffusion-weighted imaging (DWI) can be converted into virtual shear modulus (µ) to estimate liver elasticity. The purpose of this study was to correlate and compare the diagnostic performance of DWI-based virtual elastography and 2D SWE for staging hepatic fibrosis in patients with chronic liver disease, using histopathologic assessment as the reference standard.

The nickel mesh sheet (NMS) modified with capture antibodies was employed for capturing target bacteria, and metal organic frameworks decorated with palladium (Pd) and platinum (Pt) nanoparticles (MIL-88@Pd/Pt NPs) modified with detection antibodies were used for amplifying colorimetric signals. The capture efficiency of the immune NMS reached 83 %, and the detection limit of this colorimetric biosensor was 35 CFU/mL in 20 min.

Roles of CIF and chemical erosion in the ageing process and the interaction mechanisms have been systematically investigated during the electrodialysis treatment of flue gas desulfurization wastewater. The main foulants contributed to CIF were anionic polyacrylamide (APAM) and CaSO for anion-exchange membranes (AEMs) and CaSO for cation-exchange membranes.

We conducted the largest single-centre clinical study of esophageal submucosal gland duct adenoma, examining its molecular mechanisms and clinicopathological features.
Methods And Results: Between 2018 and 2023, seven cases of esophageal submucosal gland duct adenoma were identified at a tertiary medical centre; two were female and five were male, aged between 51 and 75 years (mean = 63.
Objectives: To explore the value of T1 mapping-based whole-liver histogram analysis on gadoxetic acid-enhanced MRI for predicting post-hepatectomy liver failure (PHLF).
Methods: Consecutive patients from March 2016 to March 2018 who underwent gadoxetic acid-enhanced MRI in our hospital were retrospectively analyzed, and 37 patients were enrolled. Whole-liver T1 mapping-based histogram analysis was performed.
Background: Pancreatic cancer (PC) is a major contributor to global cancer-related mortality. While the inhibitory effect of metformin (Met) on PC has been reported, the underlying mechanism remains elusive.
Methods: We established BxPC-3 cell models with miR-378a-3p and VEGFA knockdown.
Despite escalating interest in distinguishing among various types of venture capitalists (VCs) and their roles in shaping entrepreneurship and innovation, such research remains sparse in the world's second-largest VC market, i.e., China.

In oocytes, the activation of anaphase-promoting complex/cyclosome (APC/C) is a critical step in the transition from meiosis I to meiosis II.

Brilliant specifically incorporates genome and/or phenotype grouping structures, as well as phenotype correlation structures, in feature selection, effect estimation, and outcome prediction under a penalized multi-response linear regression model. Extensive simulations demonstrate its superior performance compared to competing methods.

Although the gold standard of PNI repair is still the use of autologous nerve grafts, the destruction of the donor side is inevitable. In the present study, peripheral nerve tissueoids (PNTs) composed of a Schwann cell (SC)-based neurotrophin-3 (NT-3) delivery system and a decellularized optic nerve (DON) with naturally oriented channels were engineered to investigate the mechanism of PNTs in nerve regeneration.

Background: Physical activity has emerged as a modifiable behavioral factor to improve cognitive function. However, research on adherence to remote monitoring of physical activity in older adults is limited.
Objective: This study aimed to assess adherence to remote monitoring of physical activity in older adults within a pilot cohort from objective user data, providing insights for the scalability of such monitoring approaches in larger, more comprehensive future studies.
Objective: In this study, to provide new methods for the treatment of infection, we aimed to describe the anti-inflammatory and antibacterial value of glycyrrhetinic acid on the basis of its inhibitory effect on bacterial growth (without killing the bacteria) and its reduction of the toxicity of
Methods: A mouse model was established via intranasal administration of D39, and glycyrrhetinic acid was subcutaneously injected for treatment. The wet‒dry ratio, bacterial flora content and inflammatory factor levels in the mouse lungs were determined. Cell experiments were used to evaluate glycyrrhetinic acid-mediated inhibition of PLY hemolysis and A549 cell death, and WB was used to measure glycyrrhetinic acid-mediated inhibition of PLY oligomerization.

While lithium borohydride is one of the most promising hydrogen storage materials due to its ultrahigh hydrogen storage density, high thermodynamic stability, kinetic barriers, and poor reversibility, it is far from being used in practical applications. Herein, we prepare a cubic hollow carbon dodecahedron uniformly modified with a bimetallic CoNi alloy (CoNi/NC) for preserving the stable catalytic effect of CoNi alloys toward reversible hydrogen storage. It is theoretically confirmed that bimetallic CoNi alloys effectively weaken the B-H bonds of LiBH by extending their average length to 1.

Serum amyloid A1 (SAA1), a modulator of inflammation, is elevated in the circulation of polycystic ovary syndrome (PCOS) patients and involved in ECM remodeling during tissue repair. However, the specific role of SAA1 in endometrial ECM remodeling and subsequent risk of pregnancy loss in PCOS patients remains unclear.

Summary Answer: Pregnancies following the transfer of a blastocyst with a grade C trophectoderm (TE) were associated with an increased risk of placenta previa compared to those with a blastocyst of grade A TE.
What Is Known Already: Existing studies investigating the effect of blastocyst morphology grades on birth outcomes have mostly focused on fetal growth and have produced conflicting results, while the risk of obstetric complications has rarely been reported. Additionally, growing evidence has suggested that the appearance of TE cells could serve as the most important parameter for predicting implantation and live birth.
Considerable evidence indicates that CYP2E1 is associated with a variety of inflammatory diseases. Here we evaluated CYP2E1 as a potential therapeutic target for rheumatoid arthritis (RA) and established the protective effect of a new CYP2E1 inhibitor. Gene-expression datasets were used to analyze the change in expression of CYP2E1 in RA patients; CYP2E1 activity in collagen-induced arthritis (CIA) rats was determined by HPLC.
