Abstract:

Abstract Expressing opinions is considered a significant communicative act frequently taking place in our conversations. It is one of the fairly neglected areas of research in the Arabic context. Among the studies conducted on the communicative acts, to the best of our knowledge, there has been no attempt to investigate the expressions of opinion and its strategies specifically in Jordanian Arabic (JA). To this end, the current study intends to investigate the communicative act of opinion giving in JA with reference to gender disparities. Data elicited from 50 male and 50 female speakers of JA via Discourse Completion Task and role-plays revealed that Jordanians resort to a mixture of expressions to convey their opinion clearly. They use various types of strategies, including direct expression of opinion, indirect manifestation of opinion, advice, suggesting, enumeration, prayers, address terms, complaining, personalized hedges, and rarely opting out. In addition, gender differences were also noticed in expressing this speech act. Males use direct expression strategy and imperative expression significantly more than the female participants, whereas the females used six strategies significantly more than their male counterparts: indirect expression, advice, personalized hedges, suggesting, prayers, and address terms.

Abstract:

With the continuous development of intelligent product interaction technology, the facial expression design of virtual images on the interactive interface of intelligent products has become an important research topic. Based on the current research on facial expression design of existing intelligent products, we symmetrically mapped the PAD (pleasure–arousal–dominance) emotion value to the image design, explored the characteristics of abstract expressions and the principles of expression design, and evaluated them experimentally. In this study, the experiment of PAD scores was conducted on the emotion expression design of abstract expressions, and the data results were analyzed to iterate the expression design. The experimental results show that PAD values can effectively guide designers in expression design. Meanwhile, the efficiency and recognition accuracy of human communication with abstract expression design can be improved by facial auxiliary elements and eyebrows.

Abstract:

Abstract Introduction/Objective Immunotherapy is increasingly used for the treatment of metastatic melanoma and carcinomas. PD-I (programmed death 1) and its associated ligand (PD-L1) inhibits the activation of T lymphocytes. This inhibition can be impacted by a number of drugs. Response to these drugs is predicted by assessment of PD-L1 expression. PD-L1 expression varies between 19% and 92% in melanomas and carcinomas. PD-L1 expression is less well documented for sarcomas. Methods Fifty-one sarcomas of various histopathologic types were immunohistochemically stained (IHC) for PD-L1 using the antibody clone SP263 (Ventana, Tuscan, AZ). Membrane staining of tumor cells was quantitated as a percentage of total tumor cells. Sarcomas were judged as non-expressors (less than 1%) low-expressors (1 to 50%) and high expressors (greater than 50%). The percentage of each type of sarcoma judged as an expressor was determined. Results The percentage of each type of sarcoma expressing PD-L1 is reported and 20% of sarcomas expressed PD- L1. The percentage of sarcomas expressing PD-L1 varied significantly between types but the majority of sarcomas were non-expressors. Conclusion PD-L1 IHC expression is valuable in predicting response to immune-modulating drugs. Such therapies may be useful for treatment of metastatic sarcomas. Expression of PD-L1 in carcinomas and melanomas is variable ranging from 19% to 92%. In our study, a minority (20%) of sarcomas expressed PD-L1. Other studies have shown similar results with between 1.4 and 59% (average 24%) of sarcomas expressing PD-L1. Expression appears to be type specific. These finding suggest that PD-L1 based therapy may be less useful in sarcomas than in other malignancies.

Abstract:

The transcriptome-wide association study (TWAS) has emerged as one of several promising techniques for integrating multi-scale ‘omics’ data into traditional genome-wide association studies (GWAS). Unlike GWAS, which associates phenotypic variance directly with genetic variants, TWAS uses a reference dataset to train a predictive model for gene expressions, which allows it to associate phenotype with variants through the mediating effect of expressions. Although effective, this core innovation of TWAS is poorly understood, since the predictive accuracy of the genotype-expression model is generally low and further bounded by expression heritability. This raises the question: to what degree does the accuracy of the expression model affect the power of TWAS? Furthermore, would replacing predictions with actual, experimentally determined expressions improve power? To answer these questions, we compared the power of GWAS, TWAS, and a hypothetical protocol utilizing real expression data. We derived non-centrality parameters (NCPs) for linear mixed models (LMMs) to enable closed-form calculations of statistical power that do not rely on specific protocol implementations. We examined two representative scenarios: causality (genotype contributes to phenotype through expression) and pleiotropy (genotype contributes directly to both phenotype and expression), and also tested the effects of various properties including expression heritability. Our analysis reveals two main outcomes: (1) Under pleiotropy, the use of predicted expressions in TWAS is superior to actual expressions. This explains why TWAS can function with weak expression models, and shows that TWAS remains relevant even when real expressions are available. (2) GWAS outperforms TWAS when expression heritability is below a threshold of 0.04 under causality, or 0.06 under pleiotropy. Analysis of existing publications suggests that TWAS has been misapplied in place of GWAS, in situations where expression heritability is low.

Abstract:

Abstract We detected the expressions of hsa_circRNA_000121 and hsa_circRNA_ 004183 in papillary thyroid microcarcinoma (PTMC) and explored their relationship with the invasiveness of PTMC. PTMC patients with (n = 30; metastasis group) and without lymph node metastasis (n = 30; nonmetastasis group) were included. The levels of hsa_circRNA_000121, hsa_circRNA_004183, hsa-miR-4763, hsa-miR-6775, sarcoma gene (SRC), and MMP-14 were detected with real-time polymerase chain reaction. Receiver-operating characteristic (ROC) analyzed the diagnostic value of hsa_circRNA_000121 and hsa_circRNA_004183. Binary logistic regression analysis evaluated the relationship of gene expression with PTMC invasiveness. In PTMC tissue samples, compared with the metastasis group, the expression of hsa_circRNA_000121, hsa_circRNA_004183, SRC, and MMP-14 in the nonmetastasis group decreased, while the expression of hsa-miR-4763 and hsa-miR-6775 increased. In peripheral blood, compared with the metastasis group, the expression of hsa_circ_000121 and hsa_circRNA_004183 in the nonmetastasis group decreased. Both hsa_circRNA_000121 and hsa_circRNA_004183 had good sensitivity and specificity for diagnosing PTMC lymph node metastasis, with a cut-off value of 0.796 and 0.938, respectively. However, the gene expressions were not significantly associated with PTMC lymph node metastasis. Hsa_circRNA_000121 may upregulate SRC expression through hsa-miR-4763, while hsa_circRNA 000121 may upregulate MMP-14 expression through hsa-miR-6775, thereby promoting the aggressiveness of PTMC and ultimately leading to cervical lymph node metastasis. hsa_circRNA_000121 and hsa_circRNA_004183 may become potential biomarkers of PTMC aggressiveness.

Abstract:

Various researches have shown that Cluster of Differentiation 44 (CD44) is one of the valued markers. As it plays an important role in tumor growth and metastasis but studies also suggest it as a cancer stem cell (CSC) marker in oral cancer (OC). Therefore, we aimed to explore association between the expression of CD44 and clinicopathological characteristics along with the OC prognosis.We conducted literature search through PubMed database (till October 22, 2020) to determine and evaluate the clinical and prognostic significanceof CD44 expression in OC patients. According to the inclusion criteria we finalized 9 studies with 867 OC cases. We found the positive expression of CD44 in advanced stages was prominently associated with reduced survival rate. Our analysis suggest that higher tumor expression of CD44 may predict poor survival in end staged OC patient.

Abstract:

One of the methods to evaluate the level of gene expression is a real-time quantitative polymerase chain reaction (qPCR). Interest in the study of molecular mechanisms of gene expression and its evaluation in prokaryotes is due to the lack of research on this issue and a number of methodological problems. The paper presents a study of gene expression mechanism in prokaryotes evidence from Aeromonas salmonicida AS1 gyrase B and collagenase genes. As a result of the research, Random primer and oligo (dT) primer (two 3’-terminal nucleotides of the primer complementary to stop codon nucleotides of the transcribed DNA sequence) with anchor and adapter of our own design were tested, which are used in the reaction of reverse transcription. The use of oligo (dT) primer became possible only after polyadenylation of extracted RNA using special poly-A polymerase kit. It is determined that the developed protocol of reverse transcription (RT) using oligo (dT) primer and adapter with certain sequence on its 5’-terminus designed for further annealing of the reverse primer during real-time PCR along with preliminary polyadenylation of RNA excludes specific amplification of the background genomic DNA. This technique may be applied in evaluating the expression level of low-expression genes when high background genomic DNA content is found in the RNA sample, e.g. at the end of logarithmic growth of prokaryotic cells.ContributionAll authors bear responsibility for the work and presented data.

Abstract:

4020 Background: The MRC MAGIC trial established perioperative epirubicin, cisplatin and 5FU (ECF) chemotherapy as a standard of care for patients (pts) with operable oesophagogastric (OG) cancer (Cunningham NEJM 2006). We performed transcriptomic profiling of archival MAGIC tissue to evaluate an existing intrinsic gastric cancer (GC) gene signature, to describe expression patterns of biologically informative genes and to identify prognostic or predictive markers. Methods: RNA was extracted from formalin fixed paraffin embedded (FFPE) resections and analysed with the NanoString nCounter system. Our panel comprised 151 genes including intrinsic GC (G-INT and G-DIFF) signature genes (Tan Gastroenterology 2011), and genes amplified/deleted in GC including the therapeutic targets FGFR2, EGFR, ERBB2 and c-MET (Deng Gut 2012). Data was preprocessed using nsolver analysis software with 2-step normalisation and log2 transformed. G-INT and G-DIFF subtype classification used the nearest template prediction algorithm; these were then correlated with pt characteristics and survival. The overexpression threshold was defined as deviation above the normal quantile-quantile plot. Results: Sufficient RNA for analysis was available for 209 resected pts. A pilot study (n=23) confirmed RNA quality and correlation between NanoString and Affymetrix results. RNA was more often available for pts with GC (p<0.001) and pts in the surgery alone arm (p=0.049). 70% of pts were classified into G-INT or G-DIFF intrinsic signature subtype (false discovery rate (FDR) <0.05); 61 (30%) were ambiguous. Predominantly mutually exclusive overexpression of receptor tyrosine kinase (RTK) targets EGFR, ERBB2, FGFR, and c-MET was seen in 5%, 12%, 9% and 6% of pts respectively. Conclusions: Although bias may exist in tissue availability for chemosensitive pts, transcriptomic profiling of archival FFPE from this mature phase 3 study provides powerful insight into the molecular heterogeneity of OG cancer. 70% of evaluable MAGIC pts were classified unambiguously into intrinsic GC subtypes. Mutually exclusive overexpression of targetable RTKs supports a personalized approach in OG cancer evaluating targeted drugs in relevant biological subgroups. Survival analyses are ongoing.

Abstract:

e14606 Background: Serpin B5 is a candidate tumor suppressor but its oncogenic activity has been also reported. Its function may be affected by interacting proteins. The aim of this study was to assess the relationship between serpin B5 and carcinoembryonic antigen (CEA) expressions in CRC. We also analyzed the clinicopathological significance of serpin B5 expression in colorectal cancer (CRC) patients. Methods: Two-dimensional gel electrophoresis (2-DE) analysis and matrix-associated laser desorption ionization mass spectrometry (MALDI-MS) were used to identify differentially expressing proteins according to CEA suppression. Serpin B5 and CEA expressions were evaluated by western blot and ELISA assays. Immunohistochemical expression of serpin B5 was assessed retrospectively in tissues from 377 CRC patients, and correlations between serpin B5 and clinicopathological parameters were analyzed. Results: Downregulation of serpin B5 was identified in CEA-suppressed LoVo cell line using 2-DE and MALDI-MS analyses, and further significant positive correlations between serpin B5 and CEA levels were also found in human CRC cell lines and in blood of CRC patients. Tissue expression of serpin B5 in CRC was significantly associated with serum CEA, histologic grade, stage, lymph node metastasis, liver metastasis, lymphatic and perineural invasion, and infiltrative border. High expression of serpin B5 was also associated with a reduced DFS (P = 0.001) and OS (P = 0.017). Conclusions: This is the first study describing relationship between serpin B5 and CEA expression in CRC. High expression of serpin B5 was also associated with worse prognosis in patients with CRC, and its expression may correlate with CEA levels in CRC.

Abstract:

PurposeThe objective of this study is to examine the effect of human model facial presentation (a smiling facial expression vs a neutral facial expression vs no facial presentation) on consumers' approach behavior and to determine the mechanism and boundary conditions behind such effects.Design/methodology/approachThe research consisted of four laboratory experiments.FindingsThe results of four studies showed that a smiling facial expression led to the highest score for approach behavior. Pleasure and arousal mediated the effect of facial presentation on approach behavior. In the relationship between facial presentation and approach behavior, the moderating effects of emotional receptivity and the situation were significant. To be specific, for participants with high emotional receptivity, smiling facial expressions led to the highest approach behavior; for participants with low emotional receptivity, neutral expressions led to the highest approach behavior. In a browsing situation, the approach behavior of participants in response to a smiling facial expression was the highest. However, no significant differences were found in approach behavior under the three conditions regarding a purchasing situation.Originality/valueThis study supplements the literature on human model presentation and enriches the study of facial expressions.

Abstract:

In this study, a case (HY) is described. This man, now 25 yr. old, lived in a persistent vegetative state for 6 yr. after encephalitis at the age of 10 yr. He was reportedly impaired at recognizing fear, and in everyday life, apparently had impaired recognition of anger as well. In testing with facial expressions, no obvious differences between HY and normal controls in anger perceptions were found. In this study, Japanese and Caucasian models of facial expression were used; on these tests, HY was impaired at recognizing facial expressions of anger only in the Japanese models.

Abstract:

BACKGROUND: IMP3 is an RNA binding protein, which is strongly expressed in malignant tumors, promoting tumor cell proliferation. AIM: The aim of the study was to evaluate the expression of IMP3 in laryngeal squamous cell carcinoma (SCC) and to correlate the expression of IMP3 with available clinicopathological data. METHODS: Sixty one total laryngectomy and laryngoscopic biopsies; collected from the Pathology Department, Faculty of Medicine, Cairo University. Two slides were prepared from each paraffin embedded tumor block, one slide for Hematoxylin and Eosin staining, and the other for immunohistochemical staining by IMP3 polyclonal antibody. RESULTS: Thirty-seven cases (60.7%) showed positive IMP3 expression, and a statistically significant correlation was found between IMP3 expressions in normal, dysplastic epithelium/in situ component, and the invasive malignant tumor tissue. Correlations between IMP3 expression and other available clinicopathological data were all non-significant. CONCLUSION: This study suggests that IMP3 might play a role in laryngeal SCC carcinogenesis and progression process from normal to dysplastic to malignant epithelium, and thus IMP3 might be targeted by gene therapy.

Abstract:

Chondrocytes regulate anabolic and catabolic processes to maintain the extracellular matrix components. Catabolic activities depend on the proteolytic action of the matrix -degrading enzymes including ADAMTS (A disintegrin and metalloproteinases) and MMP (Matrix Metalloproteinase). The current study explored the distribution of MMP-9 in normal articular cartilages of the embryos rabbit. Articular cartilage has grown by appositional growth that the perichondrial stem cells differentiate into chondrocytes. MMP-9 positive perichondrial stem cells or chondroblasts and early chondrocytes. Mature chondrocytes exhibited weak immunoaffinity for MMP-9. In conclusion, MMP-9 was essential during chondrocytes growth. The current study alludes to the potential role of MMP-9 during the growth of the articular cartilage.

Abstract:

The main aim of this study was to examine the norms of expressing emotions on social media. Specifically, the perceived appropriateness (i.e. injunctive norms) of expressing six discrete emotions (i.e. sadness, anger, disappointment, worry, joy, and pride) was investigated across four different social media platforms. Drawing on data collected in March 2016 among 1201 young Dutch users (15–25 years), we found that positive expressions were generally perceived as more appropriate than negative expressions across all platforms. In line with the objective of the study, some platform differences were found. The expression of negative emotions was rated as most appropriate for WhatsApp, followed by Facebook, Twitter, and Instagram. For positive emotion expression, perceived appropriateness was highest for WhatsApp, followed by Instagram, Facebook, and Twitter. Additionally, some gender differences were found, while age showed little variations. Overall, the results contribute to a more informed understanding of emotion expression online.

Abstract:

Facial Expression Recognition (FER) is a growing area of research due to its numerous applications in market research, video gaming, healthcare, security, e-learning, and robotics. One of the most common frameworks for recognizing facial expressions is by extracting facial features from an image and classifying them as one of several prototypic expressions. Despite the recent advances, it is still a challenging task to develop robust facial expression descriptors. This study aimed to analyze the performances of various local descriptors and classifiers in the FER problem. Several experiments were conducted under different settings, such as varied extraction parameters, different numbers of expressions, and two datasets, to discover the best combinations of local descriptors and classifiers. Of all the considered descriptors, HOG (Histogram of Oriented Gradients) and ALDP (Angled Local Directional Patterns) were some of the most promising, while SVM (Support Vector Machines) and MLP (Multi-Layer Perceptron) were the best among the considered classifiers. The results obtained signify that conventional FER approaches are still comparable to state-of-the-art methods based on deep learning.

Abstract:

A number of attempts have been made in the past 10 to 15 years to construct artificial systems that can simulate human expressive performance, but few systematic studies of the relationship between model output and comparable human performances have been undertaken. In this study, we assessed listeners' responses to real and artificially generated performances. Subjects were asked to identify and evaluate performances of two differently notated editions of two pieces, played by a panel of experienced pianists and by an artificial performer. The results suggest that expressive timing and dynamics do not relate to one another in the simple manner that is implemented in the model (Todd, 1992) used here, that small objective differences in the expressive profiles of different performances can lead to distinctly different judgments by listeners, and that what appears to be the same expressive feature in performance can fulfill different functions. Although one purpose of such a study is to assess the model on which it is based, more important is its demonstration of the general value of comparing human data with a model. As is often the case, it is what the model does not explain that is most interesting.

Abstract:

Improper design of the geometric elements and facilities of bikeway systems could endanger cyclists’ safety and comfort, resulting in an increased risk of bicycle accidents; such accidents sometimes have severe consequences, namely casualties. The method of expression for cyclists’ safety and comfort and the question of how the correlation of these factors with bikeway characteristics—such as the design of geometry and facilities—can be quantitatively described are the key problems facing a reduction in accident risk. Cycling workload can be employed to assess cyclists’ safety and comfort. However, there has been little quantitative expression research on this topic, with no clear definition of cycling workload. The quantitative expression of cycling workload is important for developing guidance for the safe design and operational management of bikeways; this is necessary for controlling conditions that might induce overworking and discomfort among users. In this paper, the concept of cycling workload is clearly defined based on cyclists’ comfort and safety formation mechanisms. Through a literature review and a comparative analysis, it is inferred that heart rate variability (HRV) can be used as a quantitative measure and the low-frequency–high-frequency ratio (LF/HF) can be used as a physiological signal to quantify cycling workload. A subjective scale was found to effectively express cyclists’ feelings of safety and comfort, with the performance assessed according to a human factor engineering research paradigm that classified cycling status into three qualitative levels—comfortable; a little stressful; and stressful. In order to form various cycling workload states and to obtain the relationship between LF/HF data and various bikeway characteristics, we designed a field cycling experiment. This was conducted by 24 participants who wore a physiological measuring apparatus under three different bikeway characteristic scenario types including variations in cycling width, direction, and bikeway edges at four cycling speeds in the 10–25 km/h range. Statistical analysis was used to address the collected LF/HF values and the subjective scale results, and a quantitative model for assessing cycling workload was established. By adopting a classification and regression tree (CART) algorithm as a data-mining method, the classification threshold values (ΔHRV) of three cycling workload levels were obtained: 19 indicated a level between comfortable and a little stressful; and 79 indicated a level between a little stressful and stressful.
