Endoscopists have been at increased risk because of their direct contact with patients during the COVID-19 pandemic. For patients, being diagnosed with and monitored for gastrointestinal cancer and digestive diseases in timely fashion has been challenging, given pandemic-related adjustments in endoscopy departments. We developed a novel noncontact magnetically controlled capsule endoscopy (ncMCE) system in our medical center.

Background & Aims: Both environmental factors, such as alcohol consumption and smoking, and genetic factors are strongly associated with the risk of developing chronic pancreatitis (CP). However, comprehensive understanding of their impacts on the progression of CP remains elusive.
Methods: A prospective cohort study was performed on a large cohort of CP patients with known genetic backgrounds.
The Editors of JBUON issue an Expression of Concern to ' Kutkoside-an iridoid glycoside, exerts anti-proliferative effects in drug-resistant human oral carcinoma cells by targeting PI3K/AKT signalling pathway, inducing apoptosis and suppressing cell migration and invasion', by Jun-Chi Hou, Xiao-Nan Xu, JBUON 2020;25(1):338-343; PMID: 32277652. Following the publication of the above article, readers drew to our attention that part of the data was possibly unreliable. We sent emails to the authors with a request to provide the raw data to prove the originality, but received no reply.

Methods: This is a prospective observational study including a large cohort of 965 CP patients with 11-year follow-up.
Background: The relationship between chronic pancreatitis (CP) and acute pancreatitis (AP) is complex and not well understood. CP could be preceded by antecedent episodes of AP.
Aims: The aim of this study was to explore both genetic and environmental factors associated with AP episodes before the diagnosis of CP.
Purpose: The main purpose of the current research work was to investigate the anticancer potential of Kutkoside -a naturally occurring iridoid glycoside, against drug-resistant human oral carcinoma cells along with evaluating its effects on PI3K/AKT signalling pathway, cellular apoptosis, cell migration and cell invasion.
Methods: Cell viability was assessed by using MTT colorimetric assay, while effects on cellular apoptosis were evaluated by acridine orange (AO)/ethidium bromide (EB) as well as by using flow cytometry employing annexin V-FITC. Effects on cell migration and cell invasion were evaluated by in vitro wound healing assay and transwell Matrigel assay.

Objective To investigate the effects of different inflammatory factors on hepatocyte kinase receptor(Eph)and ligand(ephrin)in human periodontal ligament fibroblasts(hPDLFs).Methods hPDLFs were stimulated with either 10 ng/ml tumor necrosis factor-α(TNF-α)or 10 ng/ml interleukin(IL)-1β,and then the expressions of Eph and ephrin at both mRNA and protein levels were determined at 0,1,2,6,12,and 24 hours.Results The levels of Eph receptors and ephrin ligand changed in a time-dependent manner in human periodontal ligament fibroblasts after treatment with TNF-α or IL-1β.

This study was to explore the value of upfront cranial radiotherapy (RT) in EGFR-mutated non-small cell lung cancer (NSCLC) with BMs compared with EGFR-TKIs alone. We searched all topic-related comparative articles in public databases (MEDLINE, EMBASE, Cochrane Library, and Web of Science) and conference proceedings.

During the process of bone remodeling,the bone homeostasis is tightly controlled by the coupling of bone resorption and bone formation,depending upon cellular communication between osteoclasts and osteoblasts. Many studies have identified that the bi-directional transduction of erythropoietin producing hepatocyte kinase receptor and ephrin ligand (Eph/ephrin) is one of signal transduction pathways in bone remodeling. This review focus on the potential role of Eph/ephrin in bone remodeling,especially in alveolar remodeling.

Objective To observe the effects of force signals and inflammatory cytokines on the expressions of functional proteins during the differentiation of periodontal ligament cells(PDLCs) into osteoclasts. Methods The caries-free premolars that needed to be removed for orthodontic treatment were collected,human periodontal ligament cells were cultured in vitro.Human PDLCs were exposed to inflammatory cytokines including interleukin(IL)-1β,-6,-23,and tumor necrosis factor alpha(TNF-α).

As a non‑nucleoside inhibitor of DNA methylation, EGCG is able to inhibit the hypermethylation of newly synthesised DNA, resulting in the reversal of hypermethylation and recovery in expression of the silenced genes. Reversion‑inducing cysteine‑rich protein with Kazal motifs (RECK) is a novel tumour suppressor gene, which negatively regulates matrix metalloproteinases, and inhibits tumour invasion, angiogenesis and metastasis.

In the title complex, [Ir(C(17)H(13)N(2))(2)(C(5)H(7)O(2))], the Ir(III) atom is hexa-coordinated in a distorted octa-hedral geometry by two C,N-bidentate 2-(5-methyl-3-phenyl-pyrazin-2-yl)phenyl (mdpp) ligands and one O,O-bidentate acetyl-acetonate ligand. The dihedral angles between the phenyl rings and the pyrazine ring are 9.56 (14) and 58.
