      • Helping People with Visual Disability Using AI

        Naif Al Otaibi,Tariq S Almurayziq International Journal of Computer ScienceNetwork S 2024 International journal of computer science and netw Vol.24 No.1

        Artificial Intelligence (AI) technology has evolved rapidly in recent years and is used in everything from banking to email management to surgery, but without the help of the visible, most of the fun features of the Internet include visual impairment. It benefits people with disabilities. The main purpose of this study is to find ways to help people with visual impairments using AI technology. A visually impaired request is made for the visually impaired. For example, when a message arrives that the program will notify you by voice (reads the sender's name, read the message, and replies to it if necessary), this is a special program installed on your mobile phone. This program uses a customized algorithm developed in Python to convert written text to voice, read text, and convert voice to written text on a message when a visually impaired person wants to respond. Then it sends the response in the form of a text message. Therefore, the research should lead to programs for people with visual impairments. This program makes mobile phones easier and more comfortable to use and makes the daily life easier for visual impairments.

      • Pain perception among patients treated with passive self-ligating fixed appliances and Invisalign?? aligners during the first week of orthodontic treatment

        Naif N. Almasoud 대한치과교정학회 2018 대한치과교정학회지 Vol.48 No.5

        Objective: This study was performed to compare the perception of pain between patients treated with passive self-ligating fixed appliances and those treated with Invisalign aligners. Methods: This prospective study conducted in Saudi Arabia used an estimated sample of 64 patients from a private dental clinic. After obtaining written informed consent, the patients were divided into two groups; one group (n = 32) was treated using passive self-ligating fixed appliances and the other group (n = 32) using Invisalign?? aligners. Immediately after fitting the appliances, the patients’ perception of pain was evaluated through a closeended and coded self-administrated questionnaire by using a visual analog scale (VAS). Their responses were recorded at 4 hours, 24 hours, day 3, and day 7. Mann-Whitney U-test, Kruskal-Wallis test, and Pearson’s chi-square test were performed for statistical analysis. Results: A lower percentage of patients treated with Invisalign aligners reported pain than did patients treated with passive selfligating fixed appliances, and these differences were statistically significant (p = 0.001). Similarly, the mean VAS score for the Invisalign group was significantly lower than that for the passive self-ligating fixed appliance group at different intervals during the first week of treatment. The intensity of pain with both appliances peaked at 24 hours (mean VAS score, 3.87) and was lowest (mean VAS score, 1.62) on day 7. Conclusions: During the first week of orthodontic treatment, patients treated with Invisalign aligners reported lower pain than did those treated with passive self-ligating fixed appliances.

      • Hepatoprotective Effects of Curcumin Against Diethyl Nitrosamine Induced Hepatotoxicity in Albino Rats

        Kadasa, Naif Mohammed,Abdallah, Haytham,Afifi, Mohamed,Gowayed, Salah Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.1

        Curcumin is widely used as a traditional medicine. This work was aimed to investigate its possible protective effect against chemically induced hepatocellular carcinoma (HCC) in rats. Fifty male albino rats were divided into five groups (n=10, each). The control group received a single dose of normal saline, the diethylnitrosamine (DENA) group received a single intra-peritoneal dose at 200mg/kg body weight, and the 3rd, 4th and 5th groups were given DENA and daily administrated curcunine (CUR) via intra-gastric intubation in doses of 300, 200 and 100 mg/kg b.wt. respectively for 20 weeks. Serum, and liver samples were used for determination of alpha feto-protein (AFP), interleukin-2 (IL-2), interleukine-6 (IL-6), serum liver enzymes (AST, ALT, ALP and GGT) levels as well the activities and gene expression of glutathione peroxidise (GPx), glutathione reductase (GR), catalase (CAT) and super oxide dismutase (SOD). Curcumin significantly lowered the serum levels of AFP, IL-2 and IL-6, ALT, ALT, and malondialdehyde (MDA) as well gene expression of IL-2 and IL-6. In contrast it increased the gene expression and activities of Gpx, GRD, CAT and SOD. The protective effect of CUR against DEN-induced hepatocarcinogenesis in albino rats was proven.

      • Proteomic Analysis of Stage-II Breast Cancer from Formalin-Fixed Paraffin-Embedded Tissues

        Abdullah Al-Dhabi, Naif,Srigopalram, Srisesharam,Ilavenil, Soundharrajan,Kim, Young Ock,Agastian, Paul,Baaru, Rajasekhar,Balamurugan, Kannan,Choi, Ki Choon,Valan Arasu, Mariadhas Hindawi Publishing Corporation 2016 BioMed research international Vol.2016 No.-

        <P>Breast cancer is the most frequently occurring disease among women worldwide. The early stage of breast cancer identification is the key challenge in cancer control and prevention procedures. Although gene expression profiling helps to understand the molecular mechanism of diseases or disorder in the living system, gene expression pattern alone is not sufficient to predict the exact mechanisms. Current proteomics tools hold great application for analysis of cancerous conditions. Hence, the generation of differential protein expression profiles has been optimized for breast cancer and normal tissue samples in our organization. Normal and tumor tissues were collected from 20 people from a local hospital. Proteins from the diseased and normal tissues have been investigated by 2D gel electrophoresis and MALDI-TOF-MS. The peptide mass fingerprint data were fed into various public domains like Mascot, MS-Fit, and Pept-ident against Swiss-Prot protein database and the proteins of interest were identified. Some of the differentially expressed proteins identified were human annexin, glutathione S-transferase, vimentin, enolase-1, dihydrolipoamide dehydrogenase, glutamate dehydrogenase, Cyclin A1, hormone sensitive lipase, beta catenin, and so forth. Many types of proteins were identified as fundamental steps for developing molecular markers for diagnosis of human breast cancer as well as making a new proteomic database for future research. </P>

        The Impact of Geopolitical Risk on Financial Conditions of Emerging Economies

        Namarta Kumari BAJAJ(Namarta Kumari BAJAJ ),Tariq AZIZ(Tariq AZIZ ),Sonia KUMARI(Sonia KUMARI ),Marim ALENEZI(Marim ALENEZI ),Naif Mansour MATHKUR(Naif Mansour MATHKUR ) 한국유통과학회 2023 The Journal of Asian Finance, Economics and Busine Vol.10 No.1

        The detrimental impacts of financial instability on the world economy during the financial crisis highlighted the requirement to understand the existing financial circumstances. Stability and developments in financial conditions are important for economic prosperity. This study analyses the impact of geopolitical risk on the economic conditions of some specific emerging economies using monthly data from January 1999 to September 2016 by applying a fixed-effects panel data model. The estimation results demonstrated that geopolitical risk has a significant, negative impact on financial conditions. It shows geopolitical risk could be seen as a key factor that contributes towards financial conditions. Further, it implies that negative shocks of high geopolitical risk experienced by emerging economies are one of the primary reasons for the financial conditions’ deterioration. The findings provide important insights for governments, policymakers, and investors. For instance, governments and politicians should refrain from expressing or producing tension, economic discomfort, or news that is likely to increase a high geopolitical risk. Maintaining a close eye on geopolitical risk and its sources may also help to stabilize financial conditions and develop a well-functioning financial system. As a result, investors would be better informed about an economy’s economic and financial conditions, allowing them to diversify their international portfolios and devise investing strategies during uncertain economic times.

        The effect of titanium and zirconium oxides additives on thermal properties of magnesium aluminate spinel

        Fahad Albanumay,Naif Alqahtani,Basheer Alshammari,Haytham Alodan,Turky Alopily,Mohammed Muhawes 한양대학교 세라믹연구소 2020 Journal of Ceramic Processing Research Vol.21 No.6

        Magnesium aluminate spinel (MgAl2O4) composites were prepared by mixing the commercial Alumina and Magnesium Oxideas starting raw materials. Titanium oxide (TiO2) and Zirconium oxide (ZrO2) were used as additives. The mixtures wereprepared as by milling of five different combinations using zirconia balls for 1 hour each. Then Cold Isostatic Press (CIP) at200 MPa pressed the batches. The material properties, such as porosity and density, and thermal expansion of the compositeswere characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and the dilatometer measurements. MgAl2O4 ceramic composites are composed of spinel and garnet structures. The thermal expansion coefficients (CTE) ofMgAl2O4 composites with and without TiO2 and ZrO2 additives under different temperature condition (25 oC to 1,300 oC) werecharacterized for spinel thermal expansion study and it shows that the comparison between the five different samplecombinations at 1,300 oC, adding TiO2 or ZrO2 by small percentage gives the lowest CTE (9.89E-06, 1.02E-05) respectively,but increasing ZrO2 increases the CTE.

        Lennox-Gastaut syndrome associated with dysgenesis of corpus callosum

        A. Bruce Janati,Naif Saad ALGhasab,Muhammad Umair,FazelHaq,Aboubaker Osman,Mohammad Sammour,AmalAbdulgadir Ahmed,Sofiane Ghorbel,Hesse Alshammeri,Maram Aldaife,Ahmad Abdollah,Afnan Ibrahim ALMubaddel 대한임상신경생리학회 2018 Annals of Clinical Neurophysiology Vol.20 No.1

        Lennox-Gastaut syndrome (LGS) is an electro-clinical syndrome composed of the triad of mental retardation, multiple seizure types, and the characteristic generalized slow spike-wave complexes in the electroencephalogram. In this article, we report on two patients with LGS whose brain magnetic resonance imaging showed dysgenesis of corpus callosum (CC). We discuss the role of CC in the genesis of secondary bilateral synchrony.

        EEG spikes resembling cardiac M-shaped waves in the EKG: the cerebral M pattern

        A.Bruce Janati,Naif S. ALGhasab,Tariq Aziz,Fazal Haq,Fahad Saad ALGhassab,Tariq Iqhbal,Rehab Khaleel Alenazy 대한임상신경생리학회 2017 Annals of Clinical Neurophysiology Vol.19 No.1

        Studies of interictal epileptiform discharges are essential for improving the diagnosis, classification, and management of epilepsy. In this case series we sought to identify the clinical and neurophysiological significance of bifid spikes, whose pattern bears a strong resemblance to the cardiac M pattern. We hypothesize that, analogous to the cardiac M pattern, the cerebral M pattern is generated by a conduction defect associated with asynchronous spatiotemporal averaging of electrical signals in the cortex, resulting in the signals reaching the scalp with different latencies. Unlike the cardiac M pattern, the pathology underlying the cerebral M pattern is unknown, although congenital CNS anomalies may be a culprit.

        Ginsenoside Rb1함유 필름의 구강 내 창상 회복 촉진 효과

        이정현,박승환,Asiri Naif Mohammed,이명한,권동건,채용권,이고은,김미선,이효설,최성철,남옥형 대한소아치과학회 2022 大韓小兒齒科學會誌 Vol.49 No.3

        This study aimed to evaluate the effects of two ginsenoside Rb1 (G-Rb1) loaded films on oral wound healing. Two types of G-Rb1 films, G-Rb1 loaded carboxymethyl cellulose (GCMC) film and G-Rb1 loaded hyaluronic acid (GHA) film, were developed. A total of 36 Sprague-Dawley rats were divided into 3 groups: control, GCMC, and GHA. After wound formation on midpalate, the control group was left without treatment, whereas the experimental groups had films attached. The specimen was analyzed clinically and histologically after 7 and 21 days. For clinical analysis, the area of incompletely re-epithelialized wound was measured. For histological analysis, the distance between the margins of the wound (soft tissue gap) was measured and the percentage of the collagen-stained area on the specimen was calculated. In clinical and soft tissue gap analysis, the GCMC group presented improved healing compared to the GHA group and the control at day 7 (p < 0.05). And, both GCMC (9.74 ± 10.12%) and GHA groups (19.50 ± 14.47%) presented greater collagen-positive pixels compared to control (0.89 ± 1.60%) at day 7 (p < 0.05). However, there were no differences in these parameters among the groups on day 21. Therefore, G-Rb1 loaded films improved oral wound healing. 이 연구의 목적은 Ginsenoside Rb1이 함유된 2가지 원형 필름의 구강 내 창상 치유에 대한 효과를 평가하는 것이다. 총 36마리의 백서를 각각 대조군, GCMC군, GHA군의 세 가지 군으로 나누어 연구를 진행하였다. 실험 동물의 정중구개부에 창상을 형성한 후, 대조군은 개방 창상으로 남겨두고, 실험군에는 각각의 필름을 적용하였다. 시편은 7일차와 21일차에 임상적, 조직학적 분석을 시행하였다. 임상적 분석을 위하여 재상피화가 일어나지 않은 창상의 면적을 계산하였고, 조직학적 분석을 위하여 스캔된 조직 표본 상에서 창상의 변연 사이 거리(Soft tissue gap)와 Collagen이 염색된 면적의 백분율을 측정하였다. 7일 희생군의 임상적 분석과 조직학적 분석 중 창상의 변연 사이 거리 모두에서 GCMC 군이 대조군과 GHA 군에 비해 높은 치유율을 보였다(p < 0.05). 7일 희생군의 GCMC 군과 GHA 군 모두에서 대조군에 비해 콜라겐 합성이 많이 발생하였다(p < 0.05). 하지만, 21일 희생군에서는 각 군간에 임상적 및 조직학적 분석 모두에서 유의미한 차이가 나타나지 않았다. 이 연구를 통해 Ginsenoside Rb1 함유 필름이 구강 내 창상 치유를 향상시킴을 확인하였다.
