Question mark ear deformity: a case study and surgical technique
Sondus Al Jadeedi,Khalifa Al-Alawi,Said Al-Busaidi 대한미용성형외과학회 2024 Archives of Aesthetic Plastic Surgery Vol.30 No.2
Clefts of the ear are rare and typically develop within the earlobe. They were first de scribed by Vincent et al. in association with urogenital anomalies. Subsequently, Cos man reported them in 1970, referring to the condition as “question mark ear,” which led to its naming. This deformity is infrequently reported and is not well-documented in the literature. In this paper, we present the first reported case in the Omani popula tion of bilateral Cosman ear, associated with a mild cranial deformity. We also discuss the social impact of this condition and introduce our corrective technique for moder ate forms of deformity.
NUMERICAL SOLUTIONS FOR SYSTEM OF SECOND ORDER BOUNDARY VALUE PROBLEMS
Al Said, E.A.,Noor, M.A.,Al Shejari, A.A. 한국전산응용수학회 1998 Journal of applied mathematics & informatics Vol.5 No.3
We investigate some numerical methods for computing approximate solutions of a system of second order boundary value problems associated with obstacle unilateral and contact problems. We show that cubic spline method gives approximations which are better than that computed by higer order spline and finite difference techniques.
CUBIC SPLINE METHOD FOR SOLVING TWO-POINT BOUNDARY-VALUE PROBLEMS
Al Said, Eisa-A. 한국전산응용수학회 1998 Journal of applied mathematics & informatics Vol.5 No.3
In this paper we use uniform cubic spline polynomials to derive some new consistency relations. These relations are then used to develop a numerical method for computing smooth approxi-mations to the solution and its first second as well as third derivatives for a second order boundary value problem. The proesent method out-performs other collocations finite-difference and splines methods of the same order. numerical illustratiosn are provided to demonstrate the practical use of our method.

There is a traditional belief in the Middle East that regular consumption of camel milk may aid in prevention and control of diabetes. The aim of this work was to evaluate the efficacy of camel milk as an adjuvant therapy in young type 1 diabetics. This 16-week randomized study enrolled 54 type 1 diabetic patients (average age 20 years) selected from those attending the outpatient diabetes clinic of the Menofia University Hospital, affiliated with Egypt's National Cancer Institute. Subjects were randomly divided into two groups of 27 patients: one received usual management (diet, exercise, and insulin), whereas the other received 500 mL of camel milk daily in addition to standard management. A control group of 10 healthy subjects was also assessed. The following parameters were evaluated at baseline and at 4 and 16 weeks: hemoglobin A1c (HbA1c), human C-peptide, lipid profile, serum insulin, anti-insulin antibodies, creatinine clearance, albumin in 24-hour urine, body mass index, and Diabetes Quality of Life score. The following parameters were significantly different between the usual-management group versus the camel milk group after 16 weeks: fasting blood sugar ($227.2\;{\pm}\;17.7$ vs. $98.9\;{\pm}\;16.2\;mg/dL$), HbA1c ($9.59\;{\pm}\;2.05$[%] vs. $7.16\;{\pm}\;1.84$[%]), serum anti-insulin antibodies ($26.20\;{\pm}\;7.69$ vs. $20.92\;{\pm}\;5.45\;{\mu}U/mL$), urinary albumin excretion ($25.17\;{\pm}\;5.43$ vs. $14.54\;{\pm}\;5.62\;mg/dL$/24 hours), daily insulin dose ($48.1\;{\pm}\;6.95$ vs. $23\;{\pm}\;4.05$ units), and body mass index ($18.43\;{\pm}\;3.59$ vs. $24.3\;{\pm}\;2.95\;kg/m^2$). Most notably, C-peptide levels were markedly higher in the camel milk group ($0.28\;{\pm}\;0.6$ vs. $2.30\;{\pm}\;0.51\;pmol/mL$). These results suggest that, as an adjunct to standard management, daily ingestion of camel milk can aid metabolic control in young type 1 diabetics, at least in part by boosting endogenous insulin secretion.
The Role of Curcuma longa Against Doxorubicin (Adriamycin)-Induced Toxicity in Rats
Al-Tahtawy, Ragaa Hosny Mohamad,El-Bastawesy, Amal Mohamad,Zekry, Zekry Khalid,Al-Mehdar, Hussain A.,Al-said, Mohamad Gamil Abdel Monaam,Aly, Soaad Shaker,Sharawy, Sabry Mohamed,El-Merzabani, Mahmuod The Korean Society of Food Science and Nutrition 2009 Journal of medicinal food Vol.12 No.2
The major component, called curcumin, of turmeric (Curcuma longa L.) (Family Zingiberaceae) powder is responsible for its biological actions. The present study aimed to prove the protective effect of turmeric extract against doxorubicin (DOX)-induced cardiac, hepatic, and renal toxicity as evaluated in rats. Body weight and urine volume of the animal groups under investigation were recorded daily throughout the experimental period. Also, the cardiac, hepatic, and renal toxicities were determined by estimating the changes in serum activities of the enzymes lactate dehydrogenase (LDH) and creatine kinase (CK), serum levels of alanine aminotransferase, aspartate aminotransferase, nitric oxide, albumin, and calcium, and kidney and liver tissue activities of superoxide dismutase and glutathione peroxidase, as well as the contents of glutathione and malondialdehyde. Hyperlipidemia was also determined, and protein and albumin changes in urine were estimated. Biochemical and histopathological findings demonstrate that turmeric extract has multiple therapeutic activities that are beneficially protective, and it has an ameliorative effect against DOX-induced cardiac toxicity and hepatotoxicity and blocks DOX-induced nephrosis. Similarly, turmeric extract inhibited the DOX-induced increase in plasma cholesterol, LDH, and CK. The present findings conclude that the turmeric extract has multiple therapeutic activities that block the cardiac, hepatic, and renal toxicities induced by DOX, and it also possibly acts as a free radical scavenger.
Impact of Social Networks in Educational Media
Al-Said, Khaleel M.,Al Said, Nidal,Hattab, Ezz The Korea Institute of Information and Commucation 2020 Journal of information and communication convergen Vol.18 No.4
This study aims to determine whether student participation on Twitter affects academic performance. The key goals of the training course were to acquire social networking knowledge and skills and to learn how to share information, be productive in discussions, and create an interest-based community. The initial sample comprised 286 students from Jordan universities, 68.4% of whom agreed to participate in the study. Undergraduate students accounted for 73.9%, and graduate students accounted for 26.1%. Only 14.3% of the students chose the Twitter-based learning model. This is a mixed-methods study that integrates quantitative and qualitative approaches. The undergraduate students were found to tweet more and have more likes, while graduate students had more followers and were following more accounts. Moreover, 21% of the participants were the most active. Spearman's correlation analysis revealed a connection between participation in social media and student performance. Therefore, the results of this study may help educational professionals and education managers.

Al Said, Elsa-A.,Noor, Muhammad-Aslam 한국전산응용수학회 1998 Journal of applied mathematics & informatics Vol.5 No.3
In this paper we introduce and study a new class of gen-eralized mildly nonlinear complementarity problems for fuzzy map-pings. We use the change of variabes technique to establish the equivalence between the generalized mildly nonlinear complementar-ity problems and the Wiener-Hopf equations. This equivalence is used to suggest and analyze a number of iterative algorithm for solv-ing the generalized mildly nonlinear complemetarity problems.

Antibiotics discharged with medical waste have had a negative impact on humans as well as aquatic organisms. Because of the severity of its eff ects and the frequency with which it appears in medical effl uent, extraction has become obligatory. Conducting mass transfer operations in microchannels is a promising technology that has several benefi ts over traditional methods. In this study, the potential of performing two-phase aqueous extraction of amoxicillin in a microchannel setup was investigated. To fully comprehend the process, it was necessary to study the system's hydrodynamics and consider the variables that had the greatest infl uence on the extraction in the microchannel. In the hydrodynamics part, the inlet junction showed an insignifi cant eff ect on the fl ow pattern type while the fl ow rate and volume fraction had a major eff ect. The plug fl ow zone was chosen for the microchannel extraction based on its high surface area and ease of separation. Aqueous two-phase system extraction (ATPS) was conducted in a microchannel to extract amoxicillin from the aqueous phase. Three process parameters were investigated, namely temperature, salt concentration, and volume fraction, which showed a direct proportionality infl uence on extraction effi ciency. The optimum operation conditions obtained were found to be, a temperature of 44.3 °C, a salt concentration of 42.6 wt.%, and a volume fraction of 0.45. This was accomplished in 1.96 min as compared to the 540 min reported for the conventional ATPS.
