Although immune checkpoint inhibitors (ICI) have revolutionized liver cancer treatment, some patients experience early tumor progression after therapy, missing the window for other potential treatments, such as neoadjuvant therapy. Therefore, identifying the predictive factors for early progression is critical for timely therapeutic adjustment and the optimization of patient outcomes. This retrospective study enrolled patients with liver cancer who received their first ICI combined with targeted therapy at the Fifth Medical Center of the PLA General Hospital between June 2022 and December 2023.

These np-Fe particles contribute to the reddening and darkening of the visible to near-infrared spectra of weathered lunar material and serve as critical indicators for assessing the maturity of lunar soil. (1) This article reviews the proposed formation mechanisms of np-Fe particles from studies of Apollo and Luna soils, including the thermal reduction of iron melts, vapor deposition caused by micrometeorite impacts, and hydrogen reduction due to solar wind exposure.

Due to the prevalence of microplastics (MPs) in aquatic environments, bivalve that experienced MP-exposure are potentially at higher risk from exposure to DSTs-producing microalgae, however, little is known about the impacts of past MP-exposure experience on the accumulation of DSTs. In this study, taking polystyrene (PS) MPs and DSTs-producing Prorocentrum lima as representatives, the impacts of MP-exposure on DSTs accumulation were evaluated in the thick-shell mussel Mytilus coruscus.

Using HS-SPME-GC-MS and HPLC, the volatile compounds were analyzed across various grain liquefaction methods, detecting 82 volatiles, including esters, alcohols, aldehydes, and acids. The concentration of flavor compounds such as esters, amino acids, phenolic acids, and organic acids varied significantly depending on the raw material used.

The protein corona would alter the gastrointestinal behavior and biological activity of the nanoparticles. Here, in this study, the influence of protein corona formation on the adverse effects of TiO nanoparticles on gut barrier function using and assays and the potential mechanism were investigated and elucidated.

However, its effectiveness in overcoming resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in patients with advanced EGFR mutations (EGFRm) NSCLC remains uncertain.
Objective: We aimed to analyze the effect of SBRT on patients with first-line EGFR-TKIs.
Tandem SAM-II/SAM-V riboswitch belongs to a class of riboswitches found in the marine bacterium ' Pelagibacter ubique'. Previous studies have demonstrated that these riboswitches have the potential for digital modulation of gene expression at both the transcriptional and translational levels. In this study, we investigate the conformational changes in the tandem SAM-II/SAM-V riboswitch binding to S-adenosylmethionine (SAM) using selective 2'-hydroxyl acylation analyzed by the primer extension (SHAPE) assay, small-angle X-ray scattering (SAXS), and oligos depressing probing.

Aim: Propose an effective talent management model to address the challenge of paediatric medical personnel shortage and lack of management experience in Underdeveloped cities of developing countries.
Methods: A crisis management plan has been implemented in a paediatric hospital in Henan, China, with a talent framework to ensure a skilled, stable workforce.
Poplar trees are crucial for timber and greening, but high levels of salt in the soil have severely limited the yield of poplar. Ethylene response factor (ERF) transcription factors play an important role in growth, development, and stress response in eukaryotes. Our study focused on the PagERF021 gene from Populus alba × P.

Background: Pregnancy-induced hypertension remains one of the important types of diseases that affect maternal and infant outcomes; prenatal and perinatal ultrasound examination is an important tool for evaluating fetal development. So, this study aimed to explore the clinical value of applying fetal heart quantification (fetal HQ) measuring left ventricular global longitudinal strain (LVGLS) and left ventricular ejection fraction (LVEF) in mid-to-late fetuses to predict neonatal complications in patients with gestational hypertension.
Methods: A retrospective summary of 146 pregnant women with gestational hypertension diagnosed from August 2020 to October 2023 into JinHua Maternal and Child Health Care Hospital was performed.
Peri-implantitis and osseointegration failure present considerable challenges to the prolonged stability of oral implants. To address these issues, there is an escalating demand for a resilient implant surface coating that seamlessly integrates antimicrobial features to combat bacteria-induced peri‑implantitis, and osteogenic properties to promote bone formation. In the present study, a bio-inspired poly(amidoamine) dendrimer (DA-PAMAM-NH) is synthesized by utilizing a mussel protein (DA) known for its strong adherence to various materials.

Due to past massive usage and persistent nature, pentachlorophenol (PCP) residues are prevalent in environments, posing a potential threat to various organisms such as sessile filter-feeding bivalves. Although humoral immunity and its crosstalk with cellular one are crucial for the maintaining of robust antimicrobic capability, little is known about the impacts of PCP on these critical processes in bivalve mollusks. In this study, pathogenic bacterial challenge and plasma antimicrobic capability assays were carried out to assess the toxic effects of PCP on the immunity of a common bivalve species, blood clam (Tegillarca granosa).
