AimsAlthough frameshift variants in the microsatellite area of shugoshin 1 (SGO1) have been reported in the context of microsatellite instability-high (MSI-H)/deficient mismatch repair gastrointestinal cancer, most have been evaluated only in early stage I–III patients, and only two of its five microsatellite regions have been evaluated. Therefore, we investigated the frequency and MSI status of microsatellite frameshift variants in gastric cancer cases, including stage IV.MethodsIn a total of 55 cases, 30 gastric cancer resection and 25 non-resection cases, DNA was extracted from both tumour and normal parts and PCR was performed. The variant was confirmed by TA cloning, and MSI was evaluated using GeneMapper software.ResultsA frameshift variant of c.973delA was observed in 16 of the 45 evaluable cases. Its frequency was 35.6%. Of the 25 cases that could be assessed for MSI status, two cases of MSI-H were associated with the c.973delA SGO1 variant. However, c.973delA SGO1 variant was also observed in four cases of microsatellite stable.ConclusionOur study shows that SGO1 frameshift variants are not always associated with MSI status.

Multipose face recognition system is one of the recent challenges faced by the researchers interested in security applications. Different researches have been introduced discussing the accuracy improvement of multipose face recognition through enhancing the face detector as Viola-Jones, Real Adaboost, and Cascade Object Detector while others concentrated on the recognition systems as support vector machine and deep convolution neural networks. In this paper, a combined adaptive deep learning vector quantization (CADLVQ) classifier is proposed. The proposed classifier has boosted the weakness of the adaptive deep learning vector quantization classifiers through using the majority voting algorithm with the speeded up robust feature extractor. Experimental results indicate that, the proposed classifier provided promising results in terms of sensitivity, specificity, precision, and accuracy compared to recent approaches in deep learning, statistical, and classical neural networks. Finally, the comparison is empirically performed using confusion matrix to ensure the reliability and robustness of the proposed system compared to the state-of art.
