Stomach adenocarcinoma (STAD) is a highly heterogeneous disease. Due to the lack of effective molecular markers and personalized treatment, the prognosis of gastric cancer patients is still very poor. The ABSOLUTE algorithm and cancer cell fraction were used to evaluate the clonal and subclonal status of 349 TCGA (The Cancer Genome Cancer Atlas)-STAD patients. Non-negative matrix factorization was used to identify the mutation characteristics of the samples. Univariate Cox regression analysis was used to determine the relationship between clonal/subclonal events and prognosis, and the Spearman correlation was used to evaluate the relationship of clonal/subclonal events to tumor mutation burden (TMB) and neoantigens. The evolution pattern of STAD demonstrated great tumor heterogeneity. TP53, USH2A, and GLI3 appeared earliest in STAD and may drive STAD. CTNNB1, LRP1B, and ERBB4 appeared the latest in STAD, and may be related to STAD's progress. Univariate Cox regression analysis identified four early genes, eight intermediate genes, and seven late genes significantly associated with overall survival. The number of subclonal events in the T stage was significantly different. The N stage, gender, and histological type were significantly different for clonal events, and there was a significant correlation between clonal/subclonal events and TMB/neoantigens. Our results highlight the importance of systematic evaluation of evolutionary models in the clinical management of STAD and personalized gastric cancer treatment. [ABSTRACT FROM AUTHOR]

This study aims to examine the perception of the Master's students of the Graduate Program in Accounting at the Federal University of Rio Grande do Norte on the efficiency, applicability and competencies of the Student Teams Achievement Divisions (STAD) collaborative method applied to accounting teaching, besides The aim is to verify, empirically, the efficiency of STAD applied to environmental accounting. The research has a qualitative and quantitative approach, in case study format, whose data were obtained through open questionnaire and participant observation. In order to verify students' perception, content analysis was performed using the ATLAS.ti 7® Software. Student's T hypothesis test was used to verify the efficiency of the method, while the Chi-square test verified the relationship between student motivation and learning progress. The results show that the STAD was efficient, considering the statistically significant difference between the scores obtained by the students before and after the application of the method. It was verified that, for the studied sample, the student's motivation is not related to the fact that he / she was successful in the achieved score. According to the students' perception, the method is capable of developing interpersonal skills such as communication, critical thinking and problem solving. In addition, STAD encouraged teamwork, which in turn motivated students during the development of the class. [ABSTRACT FROM AUTHOR]

Purpose: Stomach cancer is one of the highest incidence and mortality malignancies worldwide. Our study aimed to illustrate the somatic mutation landscape and identify molecular markers of stomach cancer. Materials and Methods: By integrated analysis of sequencing data and clinical data of stomach adenocarcinoma (STAD) from The Cancer Genome Atlas (TCGA) database, we identified several susceptibility genes and novel molecular markers and validated their potential function by the starBase website. Further, we validated the clinical value of two candidate lncRNAs in collected STAD samples by RT-qPCR. Results: We illustrated the distributions of mutation frequencies and types to get the top 20 high-mutation frequency genes in STAD. We also found 2127 mRNAs, 129 miRNAs, and 170 lncRNAs that were differentially expressed. We identified four lncRNA-miRNA-mRNA ceRNAs (PVT1, MAGI2-AS3, MIR17HG, KCNQ1OT1). Besides, 27 mRNAs (PDE4C, ID1, AQP3, VCAN, FAP, NOX4, ANGPT2, SERPINE1, SPARC, PDGFRB, FN1, MFAP2, CSMD2, INHBA, COL10A1, MATN3, P4HA3, ADAMTS12, DGKI, OLFML2B, TMEM200A, FNDC1, CTHRC1, CHST1, F5, COL5A2, TUBB3) and two lncRNAs (MIR4458HG, LINC01235) showed a significant prognostic value, and their prognostic values were validated by the starBase website. What's more, the clinical values of MIR4458HG and LINC01235 were also demonstrated in collected STAD samples. Conclusion: We constructed the lncRNA ceRNA networks and identified 20 high-mutation frequency genes and 29 prognostic markers (27 mRNAs and two lncRNAs). [ABSTRACT FROM AUTHOR]

This paper aims at enhancing writing skills by using cooperative learning strategies since recent methodologies in foreign language teaching have deviated the shift of focus from traditional teacher-oriented classes to more learner-centered contexts. Among the methods endorsed in teaching writing is the application of Cooperative Learning (CL). The use of CL has become an increasingly popular method to improve the learner's linguistic, social and communicative competence. This research investigated the effects of CL to improve the writing skill of AIU students. A questionnaire was done to spot their problems and weak points. The quasi experimental design was used, with pre-test and post-test of two different kinds of essay as an instrument. Two different kinds of studies were employed qualitatively and quantitatively to analyze the data. The students' writing was scored on the five writing components which were content, vocabulary, organization, grammar and mechanics see (Yusuf, Jusoh, & Yusuf, 2019). After analyzing the results of the post test, it was noted that there was a significant increase in the scores of students' writing in comparison with their marks of the pretest as a result of implementing cooperative learning. Subsequently, the results lent credence to the positive effects of cooperative learning in enhancing writing performance and teachers were able to involve more students to participate and the class environment was very encouraging and intriguing. EFL participants in a cooperative learning ambience managed to foster the linguistic competence that they need to acquire which was also tackled in the paper. [ABSTRACT FROM AUTHOR]

This study investigated the effectiveness of integrating Student Team Achievement Division (STAD), a structured cooperative learning method, and WebQuest, an inquiry-based technological model (IBTM) on developing university English as a Foreign Language (EFL) students' advanced-level argumentative writing skills and enhancing instructors' positive perceptions about teaching and learning. The study, which was undertaken over a 12-week academic semester, employed a mixed methods pre-test/post-test control/experimental group design whereby six intact rhetoric classes were randomly assigned to experimental and control conditions. The experimental group participants (N = 54) were enrolled in four classes and received argumentative writing instruction incorporating STADIBTM whereas their control group counterparts (N = 24) were enrolled in two classes and received the same argumentative writing instruction without STADIBTM. Four instructors who were involved with the experimental group received training on the implementation of STADIBTM. Qualitative data collection and analysis were utilized. The argumentative essay pre-tests and post-tests along with pre-treatment and post-treatment surveys were used to collect data. The quantitative results were evaluated using ANCOVA analyses. The findings showed that only the less skilled participants of the experimental and control groups were able to significantly improve their argumentative writing. However, their instructors were able to develop more positive pedagogical perceptions and perceived fewer challenges because of STADIBTM-based instruction. Further recommendations are given.

Cancer is a devastating disease that presents a major threat to human health. The protein CERS5 is responsible for synthesizing C16-ceramide, but its role in cancer is poorly understood. In this study, we examined the connection between CERS5 expression and pan-cancer prognosis, diagnosis, and the molecular mechanism involved. Kaplan-Meier survival analysis revealed variations among different cancer types. Functional enrichment analysis was conducted using gene set enrichment analysis (GSEA), and a network of protein–protein interaction (PPI) was constructed. The relationship between CERS5 and 22 immune infiltrating cell categories was detected using CIBERSORT. Single-cell analysis revealed elevated CERS5 levels in fibroblasts, which are vital in tumor immunity. The relationship between the expression of CERS5 and the immune-related genes, microsatellite instability, tumor mutational burden, and RNA modification genes in cancer were examined using the pan-cancer database. The role of CERS5 in immune regulation might be crucial to the tumor microenvironment. Pathway enrichment analysis indicated associations between CERS5 and extracellular matrix–receptor interaction, the WNT signaling pathway, and cell–cell junctions. Specifically, CERS5 was positively correlated with Cytotoxic T-Lymphocyte Associated Protein 4 (CTLA4), Programmed Cell Death 1 (PDCD1), and Lymphocyte Activating 3 (LAG3) in stomach adenocarcinoma. In vitro, knockdown of CERS5 significantly hindered gastric cancer cells' ability to proliferate, migrate invade and increased apoptotic rate. We believe that CERS5 could be a promising target for future cancer research, contributing to the development of effective therapies. • Bioinformatics pan cancer analysis reveals Ceramidesynthase5 potential mechanisms of tumorigenesis. • Ceramidesynthase5 was closely linked to the clinicopathological features and prognosis of patients. • Knockdown Ceramidesynthase5 impairs cell proliferation and migration. • Ceramidesynthase5 holds promise as a therapeutic target for gastric cancer.

Background: Fatty acid metabolism (FAM) contributes to tumorigenesis and tumor development, but the role of FAM in the progression of stomach adenocarcinoma (STAD) has not been comprehensively clarified., Methods: The expression data and clinical follow-up information were obtained from The Cancer Genome Atlas (TCGA). FAM pathway was analyzed by gene set enrichment analysis (GSEA) and single-sample GSEA (ssGSEA) methods. Univariate Cox regression analysis was conducted to select prognosis genes. Molecular subtypes were classified by consensus clustering analysis. Furthermore, least absolute shrinkage and selection operator (Lasso) analysis was employed to develop a risk model. ESTIMATE and tumour immune dysfunction and exclusion (TIDE) algorithm were used to assess immunity. pRRophetic package was conducted to predict drug sensitivity., Results: Based on 14 FAM related prognosis genes (FAMRG), 2 clusters were determined. Patients in C2 showed a worse overall survival (OS). Furthermore, a 7-FAMRG risk model was established as an independent predictor for STAD, with a higher riskscore indicating an unfavorable OS. High riskscore patients had higher TIDE score and these patients were more sensitive to anticancer drugs such as Bortezomib, Dasatinib and Pazopanib. A nomogram based on riskscore was an effective prediction tool applicable to clinical settings. The results from pan-cancer analysis supported a prominent application value of riskscore model in other cancer types., Conclusion: The FAMRGs model established in this study could help predict STAD prognosis and offer new directions for future studies on dysfunctional FAM-induced damage and anti-tumor drugs in STAD disease.
