Perception of Virtual Education Learning among Dental Residents and Faculty during the COVID-19 Pandemic: A Cross-Sectional Study.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic prompted a rapid shift from in-person to virtual learning in dental education. This study aims to assess the perceptions of virtual education learning among dental residents and faculty and employ regulatory focus theory (RFT) to understand the impact of motivational orientations on virtual learning during the COVID-19 pandemic.

Methods: In total, 46 dental residents and 10 faculty members in a dental institution participated in the study (June-August 2021).

Gut microbiota affects the activation of STING pathway and thus participates in the progression of colorectal cancer.

Background: More and more studies showed that gut microbiota was closely related to the development of colorectal cancer (CRC). However, the specific pathway of gut microbiota regulating CRC development is still unknown.

Methods: We collected fecal samples from 14 CRC patients and 20 normal volunteers for 16 S sequencing analysis.

CRP, IL-1α, IL-1β, and IL-6 levels and the risk of breast cancer: a two-sample Mendelian randomization study.

Epidemiological studies have reported a positive association between chronic inflammation and cancer risk. However, the causal association between chronic inflammation and breast cancer (BC) risk remains unclear. Here, we performed a Mendelian randomization study to investigate the etiological role of chronic inflammation in BC risk.

Electrocatalytic Mechanism of Defect in Spinels for Water and Organics Oxidation.

Spinels display promising electrocatalytic ability for oxygen evolution reaction (OER) and organics oxidation reaction because of flexible structure, tunable component, and multifold valence. Unfortunately, limited exposure of active sites, poor electronic conductivity, and low intrinsic ability make the electrocatalytic performance of spinels unsatisfactory. Defect engineering is an effective method to enhance the intrinsic ability of electrocatalysts.

Development and Psychometric Assessment of the Benefit Finding Scale for Chinese Older Adults With Chronic Diseases.

The current study sought to develop an instrument for measuring benefit finding in Chinese older adults with chronic diseases and establish its psychometric characteristics. Scale items were drafted based on a literature review, theoretical learning, the Benefit Finding Scale (BFS), the Post-Traumatic Growth Inventory, and results of interviews with 24 older adults with chronic diseases. The preliminary scale draft was constructed by performing a Delphi expert consultation and pretest with a small sample.

Establishment of an ovarian cancer omentum metastasis-related prognostic model by integrated analysis of scRNA-seq and bulk RNA-seq.

Objective: Ovarian cancer has the highest mortality rate among gynecological malignant tumors, and it preferentially metastasizes to omental tissue, leading to intestinal obstruction and death. scRNA-seq is a powerful technique to reveal tumor heterogeneity. Analyzing omentum metastasis of ovarian cancer at the single-cell level may be more conducive to exploring and understanding omentum metastasis and prognosis of ovarian cancer at the cellular function and genetic levels.

Integrated Microarray Analysis to Identify Genes and Small-Molecule Drugs Associated with Stroke Progression.

Several blood biomarkers are now considered increasingly important for stratifying risk, monitoring disease progression, and evaluating the response to therapy in ischemic stroke. The purpose of the present study was to identify the key genes associated with ischemic stroke progression and elucidate the potential therapeutic small molecules. Microarray datasets related to stroke for GSE58294, GSE22255, and GSE16561 were obtained from the Gene Expression Omnibus (GEO) database.

Stenting with high-intensity focused ultrasound ablation for distal biliary obstruction caused by pancreatic carcinoma: a meta-analysis.

Introduction: Between 42% and 77% of patients with distal malignant biliary obstruction (MBO) suffer from pancreatic carcinoma (PC).

Aim: To analyse the clinical efficacy of stenting accompanied by high-intensity focused ultrasound (HIFU) ablation in patients with distal MBO from PC.

Material And Methods: Relevant articles published through March 2021 were identified in the Pubmed, Cochrane Library, Embase, Wanfang, VIP, and CNKI databases.

Antinociceptive and anti-inflammatory activities of butein in different nociceptive and inflammatory mice models.

Background: Around 30% world population affected by acute and chronic pain due to inflammation and accidental injuries. Pain is a uncomfortable sensation and it reduce the patients' life quality.

Objective: The present exploration focuses to explore the beneficial effects of butein on the different chemical and thermal-provoked nociceptive and inflammatory mice models.

Experiences and Psychological Adjustments of Nurses Who Voluntarily Supported COVID-19 Patients in Hubei Province, China.

Background: The COVID-19 pandemic poses a major threat to global public health and economic development. Moreover, it has put considerable psychological pressure on nurses, who have played a vital role in the prevention and control of the epidemic.

Objective: This qualitative study aimed at exploring the experiences and psychological adjustments of nurses who voluntarily traveled to Hubei Province in China to provide support during the COVID-19 epidemic.

Serum neuron specific enolase level as a predictor of prognosis in acute ischemic stroke patients after intravenous thrombolysis.

Objective: Serum neuron specific enolase (NSE) concentrations are significantly correlated with stroke severity and clinical outcome in ischemic stroke patients. We aimed to determine whether the serum levels of neuron specific enolase in acute ischemic stroke (AIS) patients after intravenous thrombolysis are associated with stroke severity, and indicative of favorable outcome.

Methods: We prospectively analyzed the serum neuron specific enolase levels with for 67 subjects with AIS patients treated with intravenous recombinant tissue type plasminogen activator (rtPA) within 4.

Detection of trace levels of lead in aqueous liquids using extractive electrospray ionization tandem mass spectrometry.

A sensitive approach, based on semi-quantitative measurement of the characteristic fragments in multi-stage extractive electrospray ionization mass spectrometry (EESI-MS(n)), was developed for fast detection of trace levels of lead in aqueous liquids including mineral water, lake water, tap water, energy drinks, soft drinks, beer, orange juice, and tea. A disodium ethylene-diamine-tetraacetic acid (EDTA) aqueous solution was electrosprayed to produce negatively charged primary ions which then intersected the neutral sample plume to generate anions of EDTA-Pb(II) complexes. The charged EDTA-Pb(II) complexes were characterized with multistage collision induced dissociation (CID) experiments.
