Adverse events of 20-22G second-generation endoscopic ultrasound-guided fine-needle biopsy needles for solid lesions in the upper gastrointestinal tract and adjacent organs: Systematic review and meta-analysis.

Objectives: Previous research has conducted meta-analyses on the diagnostic accuracy of endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB). However, studies on adverse events (AEs) have been limited and sporadic and have included a highly diverse group of patients (with upper and lower gastrointestinal tract issues) and needles of varying sizes (19-22-25G). The purpose of this systematic review and meta-analysis was to determine the incidence of AEs related to the utilization of 20-22G second-generation EUS-FNB needles subsequent to puncture of the upper gastrointestinal tract and adjacent organs.

Bacterial pneumonia patients with elevated globulin levels did not get infected with SARS-CoV-2: two case reports.

Background: COVID-19 began in December 2019, rapidly spreading worldwide. China implemented a dynamic zero-COVID strategy and strict control measures after the outbreak. However, Guangzhou city ended closed-off management by the end of November 2022, leading to exposure to SARS-CoV-2.

A novel protein FNDC3B-267aa encoded by circ0003692 inhibits gastric cancer metastasis via promoting proteasomal degradation of c-Myc.

Background: Gastric cancer (GC) ranks fifth in global cancer incidence and third in mortality rate among all cancer types. Circular RNAs (circRNAs) have been extensively demonstrated to regulate multiple malignant biological behaviors in GC. Emerging evidence suggests that several circRNAs derived from FNDC3B play pivotal roles in cancer.

Sustainable Recycling of Selenium-Based Optoelectronic Devices.

Selenium (Se), the world's oldest optoelectronic material, has been widely applied in various optoelectronic devices such as commercial X-ray flat-panel detectors and photovoltaics. However, despite the rare and widely-dispersed nature of Se element, a sustainable recycling of Se and other valuable materials from spent Se-based devices has not been developed so far. Here a sustainable strategy is reported that makes use of the significantly higher vapor pressure of volatile Se compared to other functional layers to recycle all of them from end-of-life Se-based devices through a closed-space evaporation process, utilizing Se photovoltaic devices as a case study.

Live Cell Imaging and Real-Time Monitoring of Nucleolus Morphology and Mitophagy with a Red Fluorescent and Photostable rRNA-Specific Probe in Human Cancer Cells.

rRNAs are prevalent in living organisms. They are produced in nucleolus and mitochondria and play essential cellular functions. In addition to the primary biofunction in protein synthesis, rRNAs have been recognized as the emerging signaling molecule and drug target for studies on nucleolus morphology, mitochondrial autophagy, and tumor cell malignancy.

The transmembrane and cytosolic domains of equine herpesvirus type 1 glycoprotein D determine Golgi retention by regulating vesicle formation.

Accumulating evidence underscores the pivotal role of envelope proteins in viral secondary envelopment. However, the intricate molecular mechanisms governing this phenomenon remain elusive. To shed light on these mechanisms, we investigated a Golgi-retained gD of EHV-1 (gD), distinguishing it from its counterparts in Herpes Simplex Virus-1 (HSV-1) and Pseudorabies Virus (PRV).

GPX8 as a Novel Prognostic Factor and Potential Therapeutic Target in Primary Glioma.

One of the most prevalent malignant primary brain tumors is primary glioma. Although glutathione peroxidase 8 (GPX8) is intimately associated with carcinogenesis, its function in primary gliomas has not yet been thoroughly understood. Here, we leveraged Chinese Glioma Genome Atlas (CGGA), The Cancer Genome Atlas (TCGA), and Genotype-Tissue Expression (GTEx) database to investigate the association between GPX8 and overall survival (OS) of patients with primary gliomas, and our results showed that GPX8 expression was negatively correlated with OS.

Effects of hCG on DA neuronal death of Parkinson's disease.

Parkinson's disease (PD) is the second most common neurodegenerative disease worldwide, with the incidence in men being about twice as compared to women. Gender differences may provide clues for finding key targets that mediate the death of dopaminergic (DA) neurons in PD. Luteinizing hormone (LH), analog of human chorionic gonadotropin (hCG), and their receptor, luteinizing hormone/choriogonadotropin receptor (LHCGR), are associated with the pathogenesis of PD.

Nickel-catalysed radical tandem cyclisation/arylation: practical synthesis of 4-benzyl-3,3-difluoro-γ-lactams.

Enabled by nickel catalysis, a practical access to the synthesis of 4-benzyl-3,3-difluoro-γ-lactams has been developed via radical tandem cyclisation/arylation. This method features a nickel catalyst, high reaction efficiency, and good substrate tolerance and scope. This protocol proceeds through an intramolecular radical addition to form a primary alkyl radical followed by intermolecular Suzuki-type coupling.

Facile and Effective Coloration of Dye-Inert Carbon Fiber Fabrics with Tunable Colors and Excellent Laundering Durability.

Carbon fiber is a good candidate in various applications, including in the military, structural, sports equipment, energy storage, and infrastructure. Coloring of carbon fiber has been a big challenge for decades due to their high degrees of crystallization and insufficient chemical affinity to dyes. Here, multicolored carbon fiber fabrics are fabricated using a feasible and effective atomic layer deposition (ALD) technique.

Dimethyl Sulfoxide Suppresses Mouse 4T1 Breast Cancer Growth by Modulating Tumor-Associated Macrophage Differentiation.

Purpose: The universal organic solvent dimethyl sulfoxide (DMSO) can be used as a differentiation inducer of many cancer cells and has been widely used as a solvent in laboratories. However, its effects on breast cancer cells are not well understood. The aim of this study is to investigate the effect and associated mechanisms of DMSO on mouse breast cancer.

Down-regulation of MFG-E8 by RNA interference combined with doxorubicin triggers melanoma destruction.

The pathogenic mechanism of malignant melanoma involves the dynamic interplay of transformed cell and normal host cell, but cancer treatments always target each partition separately. In the tumor microenvironment, milk fat globule epidermal growth factor-8 (MFG-E8) is a secreted glycoprotein highly expressed in the vertical growth phase of melanoma, leading to tumor progression through coordinated αvβ3 and αvβ5 integrin signaling in tumor cells and host cells. Doxorubicin (Dox) is one of the most widely used antitumor drugs against a lot of solid tumors, including melanoma.

IL-7 inhibits tumor growth by promoting T cell-mediated antitumor immunity in Meth A model.

Immune suppression is well documented during tumor progression, which includes loss of effect of T cells and expansion of T regulatory (Treg) cells. IL-7 plays a key role in the proliferation, survival and homeostasis of T cells and displays a potent antitumor activity in vivo. In the present study, we investigated the antitumor effect of IL-7 in Meth A model.

Implications of the changes in serum neutrophil gelatinase-associated lipocalin and cystatin C in patients with chronic kidney disease.

Aim: Early intervention in patients with chronic kidney disease (CKD) significantly improves the prognosis. The present widely used markers of renal function, such as serum creatinine (sCr), fail to reflect early renal damage and predict the progression of disease. The authors aimed to evaluate whether neutrophil gelatinase-associated lipocalin (NGAL), a novel specific biomarker of acute kidney injury, could predict the progression of CKD.

Inhibition of tumor growth and alteration of associated macrophage cell type by an HO-1 inhibitor in breast carcinoma-bearing mice.

Heme oxygenase-1 [HO-1, also called heat shot protein 32 (HSP32)] can specifically metabolize heme to carbon monoxide, biliverdin, and ferrous iron and plays an important role in the processes of anti-inflammation, tissue protection, and antioxidative stress reaction. It has been reported that HO-1 can promote tumorigenesis and metastasis of many tumors. However, the detailed mechanisms of how HO-1 affects tumor progress are not clear.
