A Machine Learning Model for the Identification of the Holy Quran Reciter Utilizing K-Nearest Neighbor and Artificial Neural Networks

The method of identification of the Holy Quran reciter, which is entered on the various features of the acoustic wave, is referred to as the Holy Quran Reciter Identification. The Muslim communitys Holy Book is the Holy Quran. Listening to or reading the Holy Quran is one of the obligatory activities for Muslims. This research proposes a machine learning model for identifying the Holy Quran reciter using a machine learning language. Here, the presented system comprises the essential phases for a voice recognition system encompassing the processes of classification, extraction of features, preprocessing, and data acquisition. Moreover, the voices of ten known reciters are framed as a dataset in this research. The reciters are leaders of prayers in the Holy masjids of Madinah and Makkah. The analysis of the audio dataset is performed using the mel frequency cepstral coefficients (MFCC). The artificial neural network (ANN) and the k-nearest neighbor (KNN) classifiers are employed for classification. The pitch is utilized as features employed to train the KNN and ANN classifiers. The proposed system is validated using two chapters chosen from the Holy Quran. The results revealed an excellent level of accuracy. With the help of the ANN classifier, the proposed system offered 98.5% accuracy for chapter 7 and 97.2% accuracy for chapter 32. On the other hand, while utilizing KNN, the accuracy for chapter 7 is 97.02% and for chapter 32 is 96.07%. Then, the system’s performance is compared with the utilization of support vector machines (SVM) in recognition of Quranic voice reciter. The comparison results revealed that ANN is a better machine learning algorithm for voice recognition when compared to SVM

Key drivers in enhancing actual purchase of local brand in Saudi Arabia: Intention, patriotism, trust, family and government support

The study empirically investigates the important antecedents: intention, patriotism, trust, family and government support to actual purchase of local brand in Saudi Arabia.Though lot of attention is given to study the relationship between key drivers in enhancing actual purchase and intention,patriotism, trust, family and government support.But still there is a considerable confusion about how this relationship is developed and where it is directed.Each of the construct was measured on 7- point likert scale ranging from 1 strongly disagree to 7 strongly agree, where actual purchase has 6 items, intention has 8 items, patriotism has 11 items, trust has 8 items, family has 8 items and government support has 8 items.Four hundred self-administered questionnaires were distributed to target respondents among education specialists in Riyadh, Eastern Province, and Northern Borders of Saudi Arabia.252 questionnaires were completed and returned, so the response rate was 63%. The data was analyzed using Structural Equation Modeling (SEM) through AMOS 21.The goodness of fit indices of the revised structural model indicate adequate fit (GFI: 0.956, CFI: 0.984, RMSEA: 0.033, Ratio: 1.274, P-value: 0.066).The regression parameter estimates show three significant relationships between intention and patriotism (β=0.244, P-value> 0.002 and C. R=3.039), intention and family ((β=0.692, P-value = P <. 001*** and C.R=7.668), actual purchase and intention (β = 0.786, P –value = P <. 001*** and C.R = 6.904).The results show that purchase intention is positively related to consumer patriotism and purchase intention positively related to family.In addition, the results also indicate that the impacts of purchase intention on the actual purchase are significant. These results are discussed in the context of improving domestic product brand in Saudi Arabia

Prevalence and correlates of diastolic dysfunction in patients with hypertension: a cross-sectional study from in The Kingdom of Saudi Arabia

Introduction:&nbsp;diastolic dysfunction refers to impaired ventricular relaxation or filling regardless of ejection fraction and symptoms. It accounts for 8% and 25% in the hospitalized and general population, respectively. The present study was conducted to determine the prevalence and correlates of diastolic dysfunction in hypertensive patients living in Saudi Arabia. Methods:&nbsp;a multicentric, cross-sectional study was conducted from February 2019 to February 2020 at King Khalid Hospital and Prince Sultan Center for Health Services, Prince Sattam Bin Abdulaziz University hospital in Al Kharj, and Al Kharj Military Industries Corporation hospital, KSA. All patients with hypertension who underwent an echocardiography were included in the study. Logistic regression analysis was performed to determine factors associated with left ventricular diastolic dysfunction (LVDD). Results:&nbsp;the study included a total of 104 participants, where 51.9% were females andthe mean age of the patients was 48.01±12.81 years.Most patients had an abnormal echocardiography finding (64.4%, n = 67). The most common abnormalities were left ventricular (LV) hypertrophy (44.2%, n = 46), and diastolic dysfunction, (35.6%, n = 37). The study revealed that age (aOR: 6.1, 95% CI 1.17-31.3; p = 0.032) and dyslipidemia (aOR: 3.45, 95% CI 1.16-10.24; p = 0.026) have significant association with LVDD in the patients with hypertension. Conclusion:&nbsp;in conclusion, diastolic dysfunction is prevalent among older hypertensive patients and those with dyslipidaemia. Age and dyslipidaemia were non-modifiable and modifiable factors associated with LVDD in hypertensive patients, respectively

Deletion and Functional Analysis of Hepatitis B Virus X Protein: Evidence for an Effect on Cell Cycle Regulators

Background/Aims: The hepatitis B virus X protein (HBx) is a viral trans-activator that plays a crucial role in pathogenesis of hepatocellular carcinoma (HCC) via an unknown mechanism. The role of HBx in modulating cell proliferation and programmed cell death is replete with controversies. Thus, the goal of this study was to elucidate the effect of HBx and its deletion mutants on cell cycle progression in human hepatoma cells. Methods: Huh7 cells transfected with either full-length or truncated HBx were tested for their mitogenic potential based on their effect on the expression of key cell cycle-related proteins (p27, cyclin D1, p21, and p53) and pro-apoptotic proteins such as cleaved poly (ADP-ribose) polymerase (PARP) and Bax. Western blotting and immunofluorescence techniques were applied to detect changes in the expression levels and intracellular localization, respectively, of the investigated proteins. Also, Quantitative real-time PCR (qRT-PCR) was used to detect changes in RNA levels. Results: An increased anchorage-independent growth of cells transfected with HBx-WT and its deletion mutants was observed. The cell cycle regulatory molecules were differentially modulated by full-length HBx (1-154) and its different N- and C-terminal truncated forms (HBx (31-154), HBx (61-154), HBx (1-94), and HBx (61-124)). An enhanced modulation of p27, p21, and cyclin D1 was associated with HBx (1-154), whereas p53 expression was significantly inhibited by HBx (61-124). Similarly, the expression of cleaved PARP and Bax was efficiently suppressed by HBx (1-94) and HBx (61-154). Conclusion: The HBx-WT and its mutants play a critical role in the pathogenesis and progression of HCC by modulating cell cycle regulatory proteins

The Reading Perception Of Medical Staff About The Use Of Prehospital Ultrasound

This study was a focus on the use of pre-hospital ultrasound in Saudi Arabia. Generally, ultrasound is used in a high frequency by health care providers in different countries within hospitals or pre-hospital. The main point of using the ultrasound was to reduce the time of diagnosis at the hospital and decrease the rate of mortality and morbidity. The study was a cross-sectional study and was used to assess the perception of medical staff about the use of pre-hospital ultrasound. This survey study had 130 participants, and 80 of them were agreed to involve in this study. It was conducted in King Abdulaziz Hospital of National Guards, Al Ahsa and College of Applied Medical Sciences, King Saud Bin Abdul Aziz University for Health Sciences, Al Ahsa Campus, Saudi Arabia. ATLAST ti 8 was used for systematic literature review and SPSS v23 obviously for data analysis. This was a new and novel study as the Pre-hospital ultrasound was not used before in the pre-hospital. On the other hand, the findings showed that the participants displayed a high level of interest in improving their knowledge and skills of using ultrasound during its application in the pre-hospital setting. It was also recommended to have more research in future on the subject

The Association of Toll-Like Receptor 4 Polymorphism with Hepatitis C Virus Infection in Saudi Arabian Patients

Hepatitis C virus (HCV) is a single stranded RNA virus. It affects millions of people worldwide and is considered as a leading cause of liver diseases including cirrhosis and hepatocellular carcinoma. A recent study reported that TLR4 gene polymorphisms are good prognostic predictors and are associated with protection from liver fibrosis among Caucasians. This study aims to investigate the implication of genetic polymorphisms of TLR4 gene on the HCV infection in Saudi Arabian patients. Two SNPs in the TLR4 gene, rs4986790 (A/G) and rs4986791 (C/T), were genotyped in 450 HCV patients and 600 uninfected controls. The association analysis confirmed that both SNPs showed a significant difference in their distribution between HCV-infected patients and uninfected control subjects ( &lt; 0.0001; OR = 0.404, 95% CI = 0.281-0.581) and ( &lt; 0.0001; OR = 0.298, 95% CI = 0.201-0.443), respectively. More importantly, haplotype analysis revealed that four haplotypes, AC, GT, GC, and AT (rs4986790, rs4986791), were significantly associated with HCV infection when compared with control subjects. One haplotype AC was more prominently found when chronic HCV-infected patients were compared with cirrhosis/HCC patients (frequency = 94.7% and = 0.04). Both TLR4 SNPs under investigation were found to be significantly implicated with HCV-infection among Saudi Arabian population

Literature review on the efficacy of near-infrared device in improving peripheral venous access time and number of attempts in pediatric patients

IntroductionThe process of peripheral venous access (PVA) in children can be challenging for the patient and the clinician, as failed attempts often exceed the recommended two insertions, which can be painful. To speed up the process and increase success, near-infrared device (NIR) device technology has been introduced. This literature review aimed to investigate and critically evaluate the impact of NIR devices on the number of attempts and the time of the catheterization procedure in pediatric patients from 2015 to 2022.MethodsAn electronic search was performed to identify studies in PubMed, Web of Science, Cochrane Library, and CINAHL Plus, from 2015 to 2022. After applying eligibility criteria, seven studies were considered for further review and evaluation.ResultsThe number of successful venipuncture attempts ranged from 1 to 2.41 in control groups and from 1 to 2 in NIR groups. The procedural time required for success ranged from 37.5 s to 252 s in the control group and from 28.47 s to 200 s in the NIR groups. The NIR assistive device could be successfully used in preterm infants and children with special health care needs.ConclusionsWhile more research is needed to examine the training and application of NIR in preterm infants, some studies have shown improvement in placement success. The number of attempts and time required for a successful PVA may depend on several alternative factors, including general health, age, ethnicity, and knowledge and skills of healthcare providers. Future studies are expected to investigate how the level of experience of a healthcare provider performing venipuncture influences the outcome. More research is needed to explore additional factors that predict the success rate

Research Article Polymorphisms in DNA Repair Gene XRCC3 and Susceptibility to Breast Cancer in Saudi Females

We investigated three common polymorphisms (SNPs) in the XRCC3 gene (rs861539, rs1799794, and rs1799796) in 143 Saudi females suffering from breast cancer (median age = 51.4 years) and 145 age matched normal healthy controls. DNA was extracted from whole blood and genotyping was conducted using PCR-RFLP. rs1799794 showed significant association, where AA and AA+AG occurred at a significantly higher frequency in the cancer patients compared to the control group (OR: 28.1; 95% CI: 3.76-21.12; 2 : 22.82; &lt; 0.0001). The G allele was protective and presented with a dominant model. The genotype and allele frequencies of rs861539 C&gt;T and rs1799796 A&gt;G did not show a significant difference when the results in the patients and controls were compared. However, the frequency of rs1799796 differed significantly in patients with different age of diagnosis, tumor grade, and ER and HER2 status. The wild type A allele occurred at a higher frequency in the ER− and HER2− group. Our results among Saudis suggest that some variations in XRCC3 may contribute to breast cancer susceptibility. In conclusion, the results obtained during this study suggest that rs1799794 in XRCC3 shows strong association with breast cancer development in Saudi females
