Objective: Patient-derived organoids are potent pre-chemotherapy models. Due to limited research on diverse types of oral squamous cell carcinoma (OSCC) and construction efficiency, our goal was to optimize OSCC organoid models from various sites and assess drug responsiveness.
Methods: We screened and optimized culture media, employing three-dimensional techniques to construct human-derived oral squamous cell carcinoma (OSCC) organoid models in vitro.
As a serious cardiovascular disease, atherosclerosis (AS) causes chronic inflammation and oxidative stress in the body and poses a threat to human health. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a member of the phospholipase A2 (PLA2) family, and its elevated levels have been shown to contribute to AS. Lp-PLA2 is closely related to a variety of lipoproteins, and its role in promoting inflammatory responses and oxidative stress in AS is mainly achieved by hydrolyzing oxidized phosphatidylcholine (oxPC) to produce lysophosphatidylcholine (lysoPC).

Alectinib, the second-generation ALK-TKI, has been approved as first-line treatment for advanced or metastatic NSCLC patients with ALK rearrangement. Neoadjuvant therapy can achieve tumor downstaging and eradicate occult lesions in patients with potentially resectable disease.

Previous studies have suggested that cAMP signaling pathway and cGMP-PKG signaling pathway are continuously down-regulated in lung fibrosis, whereas PDE10A has a specifically expression in fibroblasts/myofibroblasts in lung fibrosis. In this study, we demonstrated that overexpression of PDE10A induces myofibroblast differentiation, and papaverine, as a PDE10A inhibitor used for vasodilation, inhibits myofibroblast differentiation in human fibroblasts, Meanwhile, papaverine alleviated bleomycin-induced pulmonary fibrosis and amiodarone-induced oxidative stress, papaverine downregulated VASP/β-catenin pathway to reduce the myofibroblast differentiation.

However, a fundamental understanding of how to regulate the growth kinetics of colloidal CsSnX NCs is still lacking and, specifically, the role of surfactants in affecting their growth kinetics remains incompletely understood. Here we report a general approach for colloidal synthesis of CsSnX perovskite NCs through a judicious combination of capping agents.
View Article and Find Full Text PDFThe synthesis of highly luminescent colloidal CsSnX (X = halogen) perovskite nanocrystals (NCs) remains a long-standing challenge due to the lack of a fundamental understanding of how to rationally suppress the formation of structural defects that significantly influence the radiative carrier recombination processes. Here, we develop a theory-guided, general synthetic concept for highly luminescent CsSnX NCs. Guided by density functional theory calculations and molecular dynamics simulations, we predict that, although there is an opposing trend in the chemical potential-dependent formation energies of various defects, highly luminescent CsSnI NCs with narrow emission could be obtained through decreasing the density of tin vacancies.

Materials And Methods: Cancer-derived IgG was knocked down by siRNA or Tet-on shRNA in the absence or presence of cisplatin in WSU-HN6 or CAL27 cells. Cell proliferation, apoptosis, and mobility were evaluated using CCK-8, flow cytometry, and transwell assays, respectively.

Objective: Lung cancer is the most prevalent cancer in the world, and lung adenocarcinoma is the most common lung cancer subtype. Identification and determination of relevant prognostic markers are the key steps to personalized cancer management.
Methods: We collected the gene expression profiles from 265 tumor tissues of stage I patients from The Cancer Genome Atlas (TCGA) databases.
BACKGROUND Resveratrol is a multifunctional bioactive substance that has effects in anti-inflammation and prevention of ischemia-reperfusion injury. This study compared the inflammation and expression of related proteins during the early stages after transplantation to explore the effects and mechanisms of resveratrol on transplanted lung. MATERIAL AND METHODS Sprague-Dawley rats were randomized to receive pretreatment of resveratrol suspension (60 mg/kg; RES group), dexamethasone (1 mg/kg; DEM group), or normal saline solution (2 mL/kg; control group) 1 h before lung transplantation.

Physical adsorption strategy was employed to fabricate two cellulase composites, and the activity of composite was characterized by hydrolysis of carboxymethyl cellulose. The NH functionalized UiO-66-NH MOF exhibited higher protein loading than the precursor UiO-66, due to the extra anchor sites of NH groups.

Traditional CO sensing technologies suffer from the disadvantages of being bulky and cross-sensitive to interferences such as CO and HO, these issues could be properly tackled by innovating a novel fluorescence-based sensing technology. Metal-organic frameworks (MOFs), which have been widely explored as versatile fluorescence sensors, are still at a standstill for aggregation-induced emission (AIE), and no example of MOFs showing a dynamic AIE activity has been reported yet. Herein, we report a novel MOF, which successfully converts the aggregation-caused quenching of the autologous ligand molecule to be AIE-active upon framework construction and exhibits bright fluorescence in a highly viscous environment, resulting in the first example of MOFs exhibiting a real dynamic AIE activity.

Bronchiolitis obliterans, which is known as non-infectious chronic lung allograft dysfunction (CLAD) in the new classification, is the greatest threat to long-term survival after lung transplantation. This study investigated the role of leukotriene B4 (LTB4) and montelukast in transplantation-related bronchiolitis obliterans and discussed the pathophysiological significance of LTB4 in chronic rejection.

The efficacy and safety of video-assisted thoracic surgery (VATS) in PS treatment has seldom been evaluated. To address this research gap, we assessed the efficacy and safety of VATS in the treatment of PS in a large Chinese cohort.

In addition, several studies have analysed the role of pTERTm in the etiology of various types of cancers, however, the results also remain inconsistent.
Methods: The genomic DNA sequence of 103 NSCLC samples were analysed to investigate the frequency of pTERTm in these patients and to establish whether these mutations are associated with their clinical data.

View Article and Find Full Text PDFBackground: Esophagectomy after pneumonectomy has been rarely reported, mainly due to the technical difficulty in performing this surgical approach. Conventional intubation to the contralateral respiratory passage is technically challenging, while the homolateral respiratory tract is absent, making oxygenation impossible.
Methods: To overcome this problem, we used venoarterial (VA) extracorporeal membrane oxygenation (ECMO) which can help achieve gas exchange despite the collapsed lung and provide a clear unobstructed surgical field for esophagectomy.
Many works showed that nerve growth factor (NGF) injected into the brain of animal model emerges potential antidepressant effects. However, this route of administration significantly restricts the application of NGF clinically. Here, we reported that intranasal NGF could provide an alternative to intraventricular injection.
