The craniofacial complex is affected by both vertical and sagittal changes. However, previous studies did not consider the changes presented by the bone bases of both mandible and maxilla in the vertical plane in the case of the adult population of the Syrian Coast, with normal permanent occlusion. Aim: is to study the degree of correlation between the cephalometric parameters which have been considered by previous studies as real indicators for the vertical alignment of the mandible and maxilla with each sex, and determine their standard values to be able to classify the facial morphology in the vertical plane into 3 patterns (long face, medium face, and short face) in the population of the Syrian Coast with permanent normal occlusion. Materials: 106 lateral cephalometric x-rays of adult patients with permanent normal occlusion, without prior orthodontic treatment were used (46 males, 60 females) from the archive of the Orthodontics and Dentofacial Orthopedics Department at Tishreen University. The age ranges were between 13-30 years old. The cephalometric tracing was carried out by hand and the cephalometric measurements that have been considered by previous studies as real indicators for the vertical alignment of the mandible and maxilla were taken. Results: There were no statically significant differences between the two sexes for the Cephalometric parameters that have been considered by previous studies as real indicators for the vertical alignment of the mandible and maxilla, standard values of the population of the Syrian Coast with permanent normal occlusion for the vertical alignment of the mandible and maxilla were obtained which were very close to the values received in previous studies, though there have been observed some variations.

Research summary
يتناول البحث دراسة التوضع العمودي للفكين عند سكان الساحل السوري من البالغين ذوي الإطباق الدائم الطبيعي. يهدف البحث إلى تحديد القيم المعيارية للمتغيرات السيفالومترية التي تعتبر مؤشراً حقيقياً للتوضع العمودي للفكين وتصنيف مورفولوجيا الوجه إلى ثلاثة نماذج (وجه طويل، وجه متوسط، وجه قصير). استخدم الباحث 106 صور شعاعية سيفالومترية جانبية لأفراد تتراوح أعمارهم بين 13 و30 سنة، وتم تحليل هذه الصور يدوياً. أظهرت النتائج عدم وجود فروقات ذات دلالة إحصائية بين الجنسين في المتغيرات السيفالومترية المدروسة، وكانت القيم المعيارية للتوضع العمودي للفكين قريبة من القيم الواردة في الدراسات السابقة. كما أظهرت النتائج أن النموذج السائد للنمو هو النمو الأفقي، وأن دوران الفك السفلي الغالب هو دوران أمامي خفيف الشدة. أوصى الباحث بإجراء دراسات موسعة تشمل فئات عمرية مختلفة وأخذ نتائج هذه الدراسة بعين الاعتبار عند التخطيط للمعالجة التقويمية.
Critical review
دراسة نقدية: يعتبر البحث مهماً في مجال تقويم الأسنان والفكين، حيث يقدم قيماً معيارية للتوضع العمودي للفكين لدى سكان الساحل السوري. ومع ذلك، يمكن توجيه بعض الانتقادات البناءة للبحث. أولاً، العينة المستخدمة قد تكون غير كافية لتمثيل كافة سكان الساحل السوري، مما قد يؤثر على تعميم النتائج. ثانياً، الاعتماد على القياسات اليدوية قد يؤدي إلى بعض الأخطاء البشرية، وكان من الممكن استخدام تقنيات تحليل رقمية أكثر دقة. ثالثاً، لم يتناول البحث تأثير العوامل البيئية والديموغرافية بشكل كافٍ، مما قد يكون له تأثير على النتائج. على الرغم من هذه النقاط، فإن البحث يضيف قيمة علمية مهمة ويشكل أساساً لدراسات مستقبلية.

Objective: To examine associations between hematological parameters ( hemoglobin, hematocrit, platelet (PLT(, red blood cell (RBC), and white blood cell (WBC)) and components of metabolic syndrome (MS) among the Syrian Coast population. Methods: Study subjects were 304 patients (140 men and 164 women), aged between 20-75 years, who attended endocrine and cardiac clinic in Tishreen and Al-Assad University Hospitals during the period from February 2015 to April 2016. MS was classified according to the International Diabetes Federation criterion. Odds ratios (OR) and 95% confidence intervals (95% CI) of MS were calculated using logistic regression procedures. Results: Hematologic parameters were significantly associated with MS components (Ptrend<0.05). and they increased with increasing number of MS components in both men and Women, All haematological parameters were positively associated with BMI, waist circumference, Triglycerides and negatively associated with HDL in male and female subjects. Among men, MS risk increased across successive quartiles of HB (OR= 4.43,9.27 and 10.18), HCT (OR= 3.57, 6 and 7.2), PLT (OR= 2.19, 4.18 and 20.86), WBC (OR= 1.59, 5.7 and 7.13) and RBC (OR= 4.49,5.32 and 9.68) as compared with those in the lowest reference group (P ≥ 0.0001). Among women, those in the highest quartiles of (HB, HCT, PLT , WBC and RBC) had respectively (1.26, 1.88, 10.93, 3.93 and 3.55)-fold increased odds of MetS as compared with those in the lowest reference group. Our findings provide further evidence in support of using hematological markers for early detection of individuals at risk for MS.
The aim of the study is to determine the relationship between the dental arch form and facial growth pattern in vertical diamond among adult patients . The study consisted of 123 patients that met the inclusion conditions.
This study has been done on Sparus aurata (Sparidae). Fish samples (297 individuals) were collected along the Syrian Coast from March 2012 to February 2014. Total length (T) was 15 - 31 cm, and the total weight (W) was 53,1 - 410,34 g. The study o f gonado somatic index (GSI) showed that the reproduction period was between November and February with a maturity peak in January (3.98±0.97)% for females ,and in December (2.19±0.29)% for males. In addition, the length at the first sexual maturity was (21.5 cm) and (22.5 cm) for males and females respectively. The results of the hepato somatic index (HSI) was compatible with the surrounding environmental and physiological changes which resulted from the change of sexual activity during the reproductive cycle. Fecundity showed a wide range for a given length, there was a linear relationship between the absolute fecundity and each of length groups and total weight. Relative fecundity was (567896-849362) egg per 1kg body weight. The frequency distribution of eggs diameters revealed the presence of one peak, and the eggs diameter during the reproduction period ranged from 0.05 to 0.3mm.
Through this research, case studies were reviewed which reviewed the dermatology department at Tishreen University Hospital in Lattakia and specialized centers for leishmaniasis and parasitic diseases in Lattakia and Tartous governorates from the beg inning of April 2018 until the end of December 2019. Where Syria is one of the areas endemic with cutaneous leishmaniasis, as we have noticed in recent years the number of skin infections has increased dramatically in all Syrian governorates, which has made leishmaniasis an important health problem that warrants study. In order to isolate and determine the type and strains of the parasite responsible for skin injuries in Syria, in order to develop a plan to combat this disease and limit its spread. Microscopy and transplantation methods are the gold standard for diagnosing cutaneous leishmaniasis, especially in poor areas where this disease is common. Through this study it was found that the age group most exposed to infection is between 16 - 40 years and that the highest incidence was among males. As for the distribution of skin lesions, the highest percentage was recorded on the face, upper and lower extremities.
This study aims to define bird species that use artificial lakes in Syrian coast, and evaluate their population size for management and protection of wildlife. Four different sites were chosen in Syrian coast, which considered the most important ar tificial lakes. Point counts method was used in bird survey in November, December, January, February, March in 2011. 15 waterbird species were recorded belonging to 9 family and 6 order. Wading birds were the main component of waterbird (60% of all species) in Syrian coast. Populations size was 1 to 300 individuals. Diversity of birds and their Populations were greatest in sites which are rich in food ( especially fish). The results showed a difference in composition of bird communities in studied sites.
