In the present study, we investigated the expression of ZHX2 and its relationship with the clinicopathological characteristics and prognosis of GC patients, and we also examined the effect of ZHX2 overexpression in GC cell lines. We used UALCAN (http//ualcan.path.uab.edu) and the Tumor Immune Estimation Resource (http//cistrome.org/TIMER) to examine ZHX2 mRNA expression, and also used Kaplan-Meier Plotter (https//kmplot.com) to determine whether ZHX2 expression was related to GC prognosis. Expression of ZHX2 protein was detected using immunohistochemical staining assays. Cell proliferation was evaluated using a cell counting kit-8 and colony formation assays, whereas apoptosis was examined by flow cytometry. Wound healing and transwell assays were used to detect cell migration and invasion. We also performed Gene Set Enrichment Analysis (https//www.gsea-msigdb.org) and used The Cancer Genome Atlas database (https//www.genome.gov/Funded-Programs-Projects/Cancer-Genome-Atlas) to examine the correlation of ZHX2 with immune infiltration. We report that ZHX2 is highly expressed in GC tissues and is significantly associated with clinical characteristics. Upregulation of ZHX2 predicted poor prognosis in GC. Furthermore, ZHX2 overexpression can promote the proliferation, invasion and migration, but inhibit apoptosis, of GC cells. High expression of ZHX2 in GC is correlated with the presence of infiltrating immune cells, including B cells, CD4+ T cells, macrophages and dendritic cells. Our data suggest that high expression of ZHX2 in GC predicts poor prognosis. In addition, ZHX2 may promote malignant behaviors of GC cells, and immune infiltration might be related to the oncogenic role of ZHX2 in GC.One nucleotide substitution in Codon 58 of HLA-C*06020101 results in a novel allele, HLA-C*06195.Test the hypothesis that women with obesity have greater gestation weight gain (GWG) with a moderately higher, vs lower, carbohydrate (CHO) diet, independent of energy intake, whereas GWG for women of normal weight would not differ by CHO group. This was a secondary analysis of data collected from glucose tolerant women with normal weight (NW) or obesity in pregnancy. Women completed a three-day food diary 16 to 20 weeks. A median split for percent kilocalories from CHO (median = 49.6%) categorized women into moderately highCHO vs lowCHO groups (n = 13-15/group). GWG was calculated between consent and the last prenatal care visit. Saracatinib research buy A two-way ANOVA was used to examine whether there was an interaction between weight status and CHO group on GWG, independent of energy intake, time between consent and last prenatal visit, and age. Women in both highCHO groups consumed more sugars and starches compared to women in the lowCHO groups (P less then .05). A significant interaction between weight status and CHO content of the diet was found (P less then .05), such that, for women with obesity, those consuming a lowCHO diet had less GWG than those consuming a highCHO diet, whereas the pattern was opposite for women with NW. Results suggest that intake of a moderately lower CHO diet may help limit GWG among glucose tolerant women with obesity. Given that women in this study were eligible only if they had normal fasting glucose concentrations in early pregnancy, it is not clear if these results would generalize to all women with obesity during pregnancy.Acute necrotic esophagitis is characterized by blacking in the esophageal mucosa and is rarely accompanied by diabetes mellitus, especially under severe hyperglycemic conditions. Here we show a very rare case of a patient who had acute and extremely severe necrotic esophagitis accompanied by hyperglycemic hyperosmolar syndrome.
Medication-related osteonecrosis of the jaw (MRONJ) is the main adverse side effect of bisphosphonates (BPs), mainly owing to the inhibitory effect of BPs on osteoclastogenesis. CircRNAs were identified to be an important factor in regulating cellular processes. The aim of this study was to explore the effect of mmu_circ_0001066 on BP-inhibited osteoclastogenesis.
The expression of MRONJ-related miRNA in RANKL-induced RAW264.7 cells treated with BP was analyzed using qRT-PCR analysis. Bioinformatics techniques were applied to screen potential circRNAs. Tartrate-resistant acid phosphatase (TRAP) staining and bone resorption assays were used to examine the effect of mmu_circ_0001066 on osteoclastogenesis. Bioinformatics analysis, luciferase reporter assays, and Western blotting assays were performed to investigate the underlying mechanism.
Four MRONJ-related miRNAs were upregulated in BP-treated RAW264.7 cells, and the expression of mmu_circ_0001066 was negatively correlated with those of MRONJ-related miRNAs. Furthermore, the upregulation of mmu_circ_0001066 partially attenuated the inhibitory effect of BP on osteoclastogenesis in RAW264.7 cells. Mechanistically, upregulated miR-16 suppressed osteoclastogenesis and miR-16 inhibitor increased osteoclastogenesis. Furthermore, we have identified that miR-16 is a downstream effector of mmu_circ_0001066.
Our results suggest that mmu_circ_0001066 played an important role in the BP-mediated suppression of osteoclastogenesis, which lays a foundation for identifying mmu_circ_0001066 as a potential biomarker for MRONJ.

To promote the discovery and development of new fungicide with novel scaffolds or modes of action, a series of novel 5-(2-chloroethyl)-1-phenyl-6-(pyridin-4-yl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one derivatives were synthesized, and evaluated for their antifungal activities.
The bioassay data showed that compound 8IIId (EC
=1.93 mg L
) is superior to boscalid (EC
=6.71 mg L
) against Valsa mali. We introduced chiral groups on the structure of 8IIId, and two chiral configurations were respectively synthesized, which are 8Vc and 8Vd. Surprisingly, 8Vc showed significant antifungal activities against Valsa mali and Physalospora piricola with EC
values of 0.22 and 0.55 mg L
. Physiological and biochemical studies showed that the primary action mechanism of compound 8Vc on Valsa mali may involve changing mycelial morphology and increasing cell membrane permeability.
These results demonstrated that 8Vc could be further modified as fungicide and provided a valuable reference for antifungal agents with pyrazolo[3,4-d]pyrimidin-4-one skeleton. © 2021 Society of Chemical Industry.

Purpose of our study was to explore the prognostic value of autophagy-related genes (ATGs) and screen autophagy-related biomarkers for OSCC. RNA-seq and clinical data were downloaded from The Cancer Genome Atlas (TCGA) database following extracting ATG expression profiles. Then, differentially expressed analysis was performed in R software and a risk score model according to ATGs was established. Moreover, comprehensive bioinformatics analyses were used to screen autophagy-related biomarkers which were later verified in OSCC tissues and cell lines. A total of 232 ATGs were extracted, and 37 genes were differentially expressed in OSCC. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis demonstrated that these genes were mainly located in autophagosome membrane and associated with autophagy. Furthermore, the risk score on basis of ATGs was identified as potential independent prognostic biomarker. Moreover, ATG12 and BID were identified as potential autophagy-related biomarkers of OSCC. This study successfully constructed a risk model, and the risk score could predict the prognosis of OSCC patients accurately. Moreover, ATG12 and BID were identified as two potential independent prognostic autophagy-related biomarkers and might provide new OSCC therapeutic targets.This study aimed to explore influencing factors for the psychological impact of coronavirus disease 2019 (COVID-19) on Wuhan college teachers, posttraumatic stress symptoms in particular, so as to inform evidence-based strategy development to ameliorate such adverse impacts. An online survey was conducted from 26 to 29 April 2020, and 1650 teachers (47.54% male; M = 40.28 years, SD = 8.3 years) enrolled in Wuhan universities and colleges participated. The results showed that the overall incidence of posttraumatic stress disorder (PTSD) among college teachers was as high as 24.55%, but the average level of PTSD score was low (M = 1.06, SD = 0.72). Logistic regression analysis showed that for those with confirmed COVID-19, the ratio was much higher, up to 2.814 (95% confidence interval [CI] [1.542, 5.136], p less then 0.001); that is, compared with those without symptoms, the ratio of PTSD increased by 181%. For those who had family members or relatives who died of COVID-19, the ratio was 5.592 (95% CI [2.271, 13.766], p less then 0.001), 459% higher than those who had no one who died. But the living places during the pandemic had no significant effect on PTSD. The findings suggest that mental health services reducing PTSD should be provided. Teachers who confirmed COVID-19 or lost loved ones to COVID-19 should be given particular care.Thyroid surgery is the primary treatment for substernal goiters, and iatrogenic injury to the recurrent laryngeal nerve (RNL) is always a risk. The literature suggests that iatrogenic lesions of the RNL post resection of substernal goiter are not equally distributed, being more frequent on the right recurrent laryngeal nerve (R-RLN) in comparison to the left recurrent laryngeal nerve (L-RLN). The relative paucity of basic anatomical and clinical reportages on R-RLN iatrogenic injuries and on the developmental factors that may help explain its higher incidence justifies this study's undertaking. Here we compare incidence of right versus left iatrogenic injuries to the RLN in surgical resections of substernal goiters and discuss the anatomical and embryological factors involved. This report is part of a larger retrospective observational cohort study of 239 patients surgically treated for substernal goiter in the Gaffrée and Guinle University Hospital, Rio de Janeiro, from 2006 to 2018. From 239 patients, 13 presented with iatrogenic RLN injury, one patient presented bilateral lesion, totalling 15 iatrogenic lesions. Our analysis showed that the R-RLN seems to be anatomically more vulnerable to injury due to the embryological underpinnings addressed in this review, R-RLN = 64.29% (n = 9) and L-RLN = 35.71% (n = 5). Pathological factors like malignancy and size of the mass are relevant issues to be considered. The knowledge of anatomical landmarks and embryological development of the thyroid and associated structures can improve our understanding and teaching of surgical anatomy, thus helping prevent and reduce the number of iatrogenic injuries on right RLNs.
