        Comparison of the effects of two different styles of orally prescribing prednisolone on postoperative sequelae of surgical extraction of an impacted mandibular third molar: a single-blind randomized study

        Mohammed Mousa H. Bakri,Faisal Hussain Alabdali,Rashed Hussain Mahzari,Thamer Jabril Rajhi,Norah Mohammed Gohal,Rehab Abdu Sufyani,Asma Ali Hezam,Ahtesham Ahmed Qurishi,Hamed Mousa Bakri,Fareedi Mukra 대한구강악안면외과학회 2024 대한구강악안면외과학회지 Vol.50 No.1

        Objectives: Surgical intervention for removal of an impacted third molar can lead to significant pain and swelling. Corticosteroids show promise for mitigating postoperative sequelae across various surgical contexts. The use of corticosteroids following minor oral surgery, though controversial, has already been proven effective. However, little research has explored peroral prescription of corticosteroids despite its convenience for outpatients and for non-surgeons like implantologists and periodontists and others who don’t have access to needle injections. The aim of this study was to address a void in the literature by comparing the effects of two styles of preoral administration of prednisolone after surgical removal of the mandibular third molar and to determine which style minimizes postoperative sequelae. Materials and Methods: A randomized, split-mouth clinical study was conducted to investigate the efficacy of two different styles of preoral prednisolone in mitigating postoperative sequelae following surgical extraction of impacted mandibular third molars. Fifteen participants were enrolled in the study. Random selection was used to determine the prescription style for the right and left mandibular arch. Group A included those who received a single dose of prednisolone 25 mg, while group B received prednisolone 5 mg postoperatively for a period of three days (5 mg three times/day on the first postoperative day, 5 mg twice/day on the second postoperative day; 5 mg once/day on the third postoperative day). Results: There was a significant difference in the distance between the corner of the mouth and tragus, which decreased with the time interval with respect to group B when compared to group A. Conclusion: The present study showed that a three-day tapered dose of prednisolone postoperatively was more effective in reducing post-extraction sequelae than a single-dose regimen.

        Analysis of Some Desert Ecosystems Vegetation in Abu Dhabi Emirate, United Arab Emirates. Effect of Land Use

        Mousa, Mohamed Taher,Ksiksi, Taoufik Salah Institute of Forest Science 2009 Journal of Forest Science Vol.25 No.1

        The present study analyses the effect of land use on the vegetation of some desert ecosystems in Abu Dhabi, United Arab Emirates (UAE). Three sites were selected to represent different types of land use, inside Umm Al-Banadeq forest, outside the forest and along Abu Dhabi-Al Ain Trucks Road. In total, fifty-two stands were examined; including a matrix of 14 species ${\times}$ 52 stands. Based on species cover data, stands were classified using TWINSPAN and ordinated using DCA. Four vegetation groups were generated at level three of classification. Zygophyllum mandavillei was dominant in most vegetation groups; Heliotropium bacciferum dominated vegetation groups inhabited the forest. Species richness, species turnover, relative evenness and relative concentration of dominance of forest vegetation groups were 2.8, 5.7, 0.7, and 2.0, respectively. The differences were attributed to both natural variability and forestry-induced changes, including change in land use, drainage and ploughing and shading by trees. Vegetation group inhabited Abu Dhabi-Al Ain Trucks Road, that were dominated by Haloxylon salicornicum and Zygophyllum mandavillei have high total cover (8.8 m per $m^{-1}$). Most community and vegetation attributes were significantly higher inside the forest than outside. Human interventions and environmental factors affected species diversity and abundance of these communities.

        Sex determination by radiographic localization of the inferior alveolar canal using cone-beam computed tomography in an Egyptian population

        Mousa, Arwa,El Dessouky, Sahar,El Beshlawy, Dina Korean Academy of Oral and Maxillofacial Radiology 2020 Imaging Science in Dentistry Vol.50 No.2

        Purpose: The purpose of this study was to evaluate possible differences in the location of the inferior alveolar canal in male and female Egyptians. Materials and Methods: This cross-sectional retrospective study involved the evaluation of 210 CBCT scans of Egyptian individuals (18-70 years old). The inferior alveolar canal was localized by measuring 8 linear dimensions: 2 for the vertical localization of the mental foramen (superior and inferior to the mental foramen), 4 at the first molar bifurcation for the vertical and horizontal localization of the inferior alveolar canal (superior, inferior, buccal, and lingual to the inferior alveolar canal), and 2 for the horizontal localization of the mandibular foramen (anterior and posterior to the mandibular foramen). The measurements were statistically analyzed via comparative analysis, stepwise logistic regression, and receiver operating characteristic (ROC) curve analysis. Results: Six of the 8 measured distances differed to a statistically significant extent between the sexes. Regression analysis suggested a logistic function with a concordance index of 84%. The diagnostic accuracy capabilities of the linear measurements as sex predictors were calculated using ROC analysis, and the 6 best predictors for sex determination were selected and ranked from highest to lowest predictive power. Moreover, combining these 6 predictors increased the predictive power to 84%. Conclusion: The location of the inferior alveolar canal in the Egyptian population varies significantly by sex; accordingly, this anatomic landmark could be used as a reliable indicator of sexual dimorphism.

        Effect of Ultra Violet (UV) Irradiation as an Environmentally Friendly Pre-Treatment on Dyeing Characteristic and Colorimetric Analysis of Wool

        Mousa Sadeghi-Kiakhani,Siyamak Safapour,Fahimeh Sabzi,Ali Reza Tehrani-Bagha 한국섬유공학회 2020 Fibers and polymers Vol.21 No.1

        Low-energy UV lamps were used for the pretreatment of wool yarns and its effects were investigated in terms ofsurface morphology, tensile strength, and percentage dye uptake. Subsequently, raw and UV-treated wool yarns were dyedwith Cochineal dye and the essential parameters affecting the dyeing process (i.e., temperature, pH, duration) weredetermined. The results showed that the color strength of the samples increased by (a) increasing the pre-treatmenteffectiveness (i.e., UV irradiation strength and its duration), and (b) increasing the influential dyeing parameters (i.e., highertemperature, higher initial dye concentration in the dye bath, longer dyeing time, and acidic pH). The UV irradiationpretreatment also enhanced the color fastness properties of the dyed samples under the same dyeing conditions. The resultssuggested that an eco-friendly, acid-free, and relatively cheaper dyeing process could be developed for the wool fiberspretreated with scalable and straightforward UV irradiation pretreatment.

      • In vitro degradation behavior and cytocompatibility of a bioceramic anodization films on the biodegradable magnesium alloy

        Mousa, H.M.,Hussein, K.H.,Pant, H.R.,Woo, H.M.,Park, C.H.,Kim, C.S. Elsevier 2016 Colloids and surfaces. A, Physicochemical and engi Vol.488 No.-

        <P>Magnesium (Mg), and its alloys have good potential for using in biomedical applications due to its good mechanical properties and biodegradability. However, the poor corrosion resistance and insufficient mechanical stability of Mg in biological fluids have limited its clinical applicability. As a result, surface modification techniques are being investigated to improve corrosion resistance for biomedical applications. In this study, a bioactive CaP film were deposited on the surface of the AZ31B magnesium alloy via anodization with SBF solution used as the electrolyte with and without ZrO2 Nanoparticles (NPs). The samples were evaluated and characterized in vitro to assess their degradation and cytocompatability behaviour via FE-SEM, electrochemical corrosion test, immersion test, and cell culture tests. The results indicate that the AZ31B Mg alloy surface anodized in SBF with and without ZrO2 NPs consists of CaP nanoplate leaf-like apatite structures and porous 3-D structures, respectively. The nanomorphology showed uniform growth on the anodized surface that had created the porous layer on the surface of the samples three days after immersion in the SBF solution. The formation of such nanostructures on the anodized sample could provide the implant materials with extra biocompatibility. Moreover, this unique deposited layer can improve the corrosion resistance and cytocompatability of the Mg alloys, which make it a promising material for use in biomedical applications.

        A Systems Engineering Approach for CEDM Digital Twin to Support Operator Actions

        Mousa, Mostafa Mohammed,Jung, Jae Cheon The Korean Society of Systems Engineering 2020 시스템엔지니어링학술지 Vol.16 No.2

        Improving operator performance in complex and time-critical situations is critical to maintain plant safety and operability. These situations require quick detection, diagnosis, and mitigation actions to recover from the root cause of failure. One of the key challenges for operators in nuclear power plants is information management and following the control procedures and instructions. Nowadays Digital Twin technology can be used for analyzing and fast detection of failures and transient situations with the recommender system to provide the operator or maintenance engineer with recommended action to be carried out. Systems engineering approach (SE) is used in developing a digital twin for the CEDM system to support operator actions when there is a misalignment in the control element assembly group. Systems engineering is introduced for identifying the requirements, operational concept, and associated verification and validation steps required in the development process. The system developed by using a machine learning algorithm with a text mining technique to extract the required actions from limiting conditions for operations (LCO) or procedures that represent certain tasks.

        Mousa, Fariss T.,Kim, Sang Kyun,Rutherford, Matthew A. Emerald Group Publishing Limited 2016 MANAGEMENT DECISION Vol.54 No.3

        <P><B>Purpose</B></P> <P> – The purpose of this paper is to explore the role of the top management team (TMT) in determining whether IPO firms in high-tech industry will engage in acquisitions during the post-IPO period. </P> <P><B>Design/methodology/approach</B></P> <P> – The authors collect IPO and TMT data from firm prospectuses, and acquisition and financial data from Securities Data Company Platinum and Compustat, respectively. Poisson regression analysis is applied to test the effect of TMT characteristics on acquisition activity. </P> <P><B>Findings</B></P> <P> – Using 135 IPO firms, the authors find evidence that TMT composition directly influences acquisition activity of IPO firms during the post-IPO period. Specifically, the authors find that TMT experience serving as members other firms’ boards and TMT experience in senior level management positions are both positively associated with acquisition activity. TMTs with prior IPO experience and TMTs with longer organizational tenures are negatively associated with acquisition activity. </P> <P><B>Originality/value</B></P> <P> – This study is among the first to examine the impact of TMT demography on newly public firms’ acquisition activity. In doing so, it adds meaningfully to the understanding of the factors driving such firms’ strategic behavior.</P>
