This study was conducted at AL Assad University Hospital in Latakia in 2012. It was a prospective study of pregnant patients admitted Department of Obstetrics and Gynecology during the period between 1\9\2012 and 1\9\2013. These patients had regular menstrual information and were in 37th week or more of gestation and did not have any disease in the mother or fetus affecting the growth of the fetus. The study included 122 patients regardless of the mode of delivery. Each patient's information was documented: estimated gestational age by LMP (last menstrual period) and estimated gestational age by ECHO using (BPD : biparietal diameter, FL: femur length) during the 24-hour from delivery, presentation and amount of liquid by ECHO. Gestational age ranged between 37 and 41.5 weeks "with an average of 38.6 weeks" and a standard deviation of 1.1 weeks" by LMP. Results showed almost convergent values based on all BPD and FL. There was also a stronger correlation between the ages of pregnancy estimated FL, LMP than BPD, LMP. Moreover, there was presence of a strong correlation between the ages of pregnancy estimated using BPD, FL and LMP when the presentation was breech. It was also observed that the presence of a good amount of liquid is necessary to estimate the age pregnancy ultrasound.

Research summary
أجريت هذه الدراسة في مشفى الأسد الجامعي في اللاذقية عام 2012، وهي دراسة مستقبلية للمريضات الحوامل اللاتي يراجعن قسم التوليد وأمراض النساء. شملت الدراسة 122 مريضة بغض النظر عن طريقة الولادة، وتم توثيق المعلومات الخاصة بكل مريضة مثل عمر الحمل المقدر باستخدام آخر دورة طمثية (LMP) وعمر الحمل المقدر باستخدام الأمواج فوق الصوتية (BPD: القطر بين الجداريين، FL: طول الفخذ) خلال 24 ساعة من الولادة. أظهرت النتائج أن هناك ارتباطًا قويًا بين أعمار الحمل المقدرة باستخدام FL وLMP مقارنةً بـ BPD وLMP. كما تبين أن وجود كمية جيدة من السائل الأمنيوسي ضروري لتقدير عمر الحمل بالأمواج فوق الصوتية. الدراسة خلصت إلى أن الأمواج فوق الصوتية هي وسيلة موثوقة لتقدير عمر الحمل، خاصة عند وجود كمية جيدة من السائل الأمنيوسي وعندما يكون المجيء مقعديًا. توصي الدراسة بإجراء دراسات أخرى تشمل الحوامل والأجنة الذين يعانون من أمراض تؤثر على القياسات الحيوية الجنينية بالأمواج فوق الصوتية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال تقدير عمر الحمل باستخدام الأمواج فوق الصوتية، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، حجم العينة كان محدودًا (122 مريضة) مما قد يؤثر على تعميم النتائج. ثانياً، الدراسة لم تأخذ في الاعتبار العوامل الأخرى التي قد تؤثر على دقة القياسات مثل وزن الأم وحالة الجنين الصحية بشكل عام. ثالثاً، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت مقارنة مع طرق أخرى لتقدير عمر الحمل مثل الفحوصات البيوكيميائية. وأخيراً، توصي الدراسة بإجراء دراسات مستقبلية تشمل الحوامل والأجنة الذين يعانون من أمراض، وهو ما يعكس الحاجة إلى مزيد من البحث في هذا المجال.
Questions related to the research
  1. ما هو الهدف الرئيسي من الدراسة؟

    الهدف الرئيسي من الدراسة هو مقارنة العمر الحملي المقدر بالتصوير الصدوي مع العمر الحملي الطمثي لمعرفة مدى الاعتماد على معطيات التصوير الصدوي لوحدها عند المريضات اللاتي لا يتذكرن التواريخ الطمثية بدقة.

  2. ما هي النتائج الرئيسية التي توصلت إليها الدراسة؟

    النتائج الرئيسية هي أن هناك ارتباطًا قويًا بين أعمار الحمل المقدرة باستخدام FL وLMP مقارنةً بـ BPD وLMP، وأن وجود كمية جيدة من السائل الأمنيوسي ضروري لتقدير عمر الحمل بالأمواج فوق الصوتية.

  3. ما هي التوصيات التي قدمتها الدراسة؟

    توصي الدراسة بإجراء دراسات أخرى تشمل الحوامل والأجنة الذين يعانون من أمراض تؤثر على القياسات الحيوية الجنينية بالأمواج فوق الصوتية.

  4. ما هي القياسات الحيوية التي تم استخدامها في الدراسة لتقدير عمر الحمل؟

    القياسات الحيوية التي تم استخدامها هي القطر بين الجداريين (BPD) وطول الفخذ (FL).

Total Polyphenol was studied in olive leaves collected from Lattakia area (AlQurdaha zone), where Phenolic compounds were extracted from dry Olive leaves by using two extraction methods: maceration and Ultrasonic Device. By the both two methods a study was carried out on the extraction solvent concentration effect where the extraction was done by using the mixture of Ethanol-Water with different percentages (60,70,80 %). As well, The extraction temperature effect was studied at the both methods at (20,30, 40°C); in addition to the study of the extraction time effect. At the method of Maceration Extraction, the total polyphenols amount was studied in dry olive leaves after extraction during different times (24,48,72 h). While at the Ultrasonic Extraction the times were (10,20,30 min). The study showed that the highest amount of phenolic compounds were existed in dry olive leaves which were extracted by Ultrasonic Waves with the concentration of the solvent ethanol-water 80%, temperature of 40°C, and with an extraction time of 20min.
Breast cancer is the second leading cause of death of women in the world. The early detection gives a better chance to cure it. Physicians diagnose breast tumors by analyzing the characteristics of the lesion in ultrasound images. Shape data, provi ded by a tumor contour, is important to physicians in making diagnostic decisions. However, due to the increasing use of technology in medicine, a computer aided detection systems (CAD) have been built to help the expert. This research focuses on using a level-set method as an effective lesion segmentation method for breast ultrasound images. By applying non-local means filter on image, the unwanted speckle noise will be removed and the image's important details will be preserved. Then the initial contours are sketched using the GUI in order to apply level-set method which delineates the contour of the lesion in breast ultrasound image. The proposed method was found to determine the breast tumor contours that are very similar to manual-sketched contours (about 96%).
In this study we used ultrasonic technology as a means of enhancing dyeing process efficiency of polyester fibers with disperse dyes, which had frequency 42kHz and, we studied the behavior of dye when the polyester dyed with (US) and with traditional dyeing methods (without US).
The study is carried on 65 pregnant patients attending the outpatient clinics and inpatient department of Obstetrics and Gynecology of Al Assad University Hospital from February- 2013 until February- 2014. They were divided to three groups. The fir st is preterm labor with intact membranes (25 patients). The second is PROM (20 patients). The third one is control group (20 patients). All of them were submitted to ultrasonography to find cervical changes (cervical canal length and diameter of internal os in order to predict preterm delivery. Cervical canal length has a sensitivity of 91.43%, a specificity of 100%, a positive predictive value of 100%, a negative predictive value of 76.92%, and a relative risk (95% CI) of 4.33 (1.61-11.69) among patients with short cervical canal length and those with normal cervix. Diameter of internal os as a predictor of preterm delivery has a sensitivity of 60%, a specificity of 60%, a positive predictive value of 84%, a negative predictive value of 30%, and a relative risk (95% CI) of 1.2 (0.86–1.68).
This Paper offers an effective method to measure the length of the femur in Fetal Ultrasound Images, it applies a series of steps starting with the reducing amount of noise in these images, and then converted them to a binary form and uses morphol ogical operations to segment the femur and isolate it from the rest of the image objects, then it applies an Edge Detector in order to find the edges of the bone, then uses the Hough Transform to detect straight lines in the image. we apply overlapping for resulted lines on the original image, finally we choose the most significant and longest straight line which is corresponding to the length of the femur. The proposed method facilitates the measurement of the femur without the help of a physician through a series of steps.
