Abdominal Aortic Aneurysm (AAA) is the most common type of true aneurysm and have a high incidence to rupture. The introduction of endovascular grafting was a milestone in the treatment of patients with AAA as it provided a treatment option for those patients with large aneurysms with inoperable conditions because of the presence of significant medical co-morbidities. By this innovation, an early benefit in quality of life can be achieved, as it relates to reducing hospital stay and recovery period in comparison with open surgery. In our study, we enrolled 20 patients to describe initial and midterm results of Endovascular Aortic Aneurysm Repair (EVAR) in patients with infra-renal abdominal Aortic Aneurysm.

Cet ouvrage traite la problématique de l'économie non officielle en Algérie .Il tend à la compréhension de fonctionnement de cette économie, à cerner ses effets positifs et négatifs sur le plan économique et social, tout en s¿interrogeant sur ses raisons d¿être et les mécanismes susceptibles de contribuer à son expansion: le choix économique, ou la contrainte faute d¿autres alternatives. Pour cela, nous avons réalisé une enquête auprès d¿un échantillon représentatif de la population totale; 343 ménages soit près de 843 actifs dans la wilaya de Tizi-Ouzou(Algérie). Les résultats obtenus par l¿analyse de la satisfaction montrent que dans une Wilaya où presque la moitié des occupés sont informels (46.16 %) et où le taux de chômage avoisine les 14 %, l¿économie informelle est considérée comme un mal nécessaire.

The book majorly deals with two state-of-the-art problems in the field of molecular electronics. The first problem is the mediation of excessive heat generated in the electronic chip due to the moving charges. The second issue is the production of pure graphene suitable for electronic applications. The suggested partial solution to the first problem is by functionalization, where graphene sheets are functionalized with specific molecules to increase its heat dissipation. In the meanwhile, the second case includes treating silicon carbide with hydrogen to generate highly pure graphene sheets. Both cases are mainly dealt with from the theoretical point of view but also support by experimental results.

The sense of smell allows organisms to detect a large number of volatile substances in the environment. Olfaction is an essential sense for the survival of any organism, especially to determine the edibility of the food or to detect potential dangers. This sense also plays a major role in the social behavior of many species, such as partner choice or group recognition. In humans, olfaction is involved in the acceptability of food as well as in the recognition of the environment. The aroma characteristics of molecules can evaluate by computational methods for its great advantages. The quantitative structure activity/propriety relationship QSAR/QSPR models are theoretical methods used to investigate the relations between chemical structure (molecular descriptors) of a set of compounds and their biological activity or chemical property. Therefore, these methods make it possible to evaluate, interpret and predict the aroma characteristic of volatile compounds considered as bioactive molecules able to activate biological targets (olfactory receptors).

Cette recherche a été préparée au département de génie Electrique-Energétique-Automatique de l¿Ecole Nationale des Sciences Agro-Industrielles ( ENSAI ) de l¿Université de Ngaoundéré au sein du Laboratoire Energie Signal Imagerie et Automatique ( LESIA http://lesia-cameroun.org ) en partenariat avec le Laboratoire de Biophysique, Biochimie Alimentaire et Nutrition (LBBAN) de l¿Université de Ngaoundéré.

The chemistry of chalcones has generated intensive scientific studies throughout the world. Especially interest has been focused on the synthesis and biodynamic activities of chalcones. The name ¿Chalcones¿ was given by Kostanecki and Tambor1. These compounds are also known as benzalacetophenone or benzylidene acetophenone. In chalcones, two aromatic rings are linked by an aliphatic three carbon chain. Chalcone bears a very good synthon so that variety of novel heterocycles with good pharmaceutical profile can be designed.

Multinodular goiter is a common disorder of the thyroid gland, whenever surgery is indicated for a simple multinodular goiter; the current trend usually is to do total thyroidectomy that leads the patient to take a lifelong hormone replacement therapy, a daily dependence on it and regular visits to hospital to check hormone levels are burdensome. Other problems that may interfere with reaching a euthyroid status using replacement therapy are malabsorption and noncompliance of patients Thyroid autotransplantation is to leave thyroid tissue in the body that might be able to avoid or reduce severity of post-thyroidectomy hypothyroidism in noncompliant patients and if recurrence occurs it would not be in the neck, thus avoiding compression on the trachea and avoiding dangerous reoperation in the neck In this study we are trying to assess survival and function of autotransplanted thyroid tissue after total thyroidectomy in patients with multinodular goiter, and relation between amount of grafted thyroid tissue and duration after which patient get euthyroid status, as alternative method to avoid replacement therapy.

Ce livre s¿adresse à tous les étudiants en 1ère année d¿études supérieures scientifiques (Classes préparatoires et 1er cycle universitaire; ST, SM, MI). Il est composé de quatre chapitres sous forme de séries. Nous avons introduit les parties « faire le point », « application directe du cours » et « ce qüil faut retenir des exemples » au début de chaque série. À la suite de l¿énoncé des exercices, il existe une partie sous forme de « conseils », se présenter ainsi : ¿ soit une idée de résolution est proposée; ¿ soit une question est posée pour la mise en évidence d¿un phénomène; ¿ soit un théorème est énoncé,¿. ¿ Pour certains exercices nous mettons le lecteur en garde contre leur difficulté. Nous souhaitons que cet ouvrage puisse aider de manière efficace une majorité d¿étudiants.

Objective: The objective of our study was to evaluate how to categorize breast lesions detected at contrast-enhanced breast MRI in accordance with the imaging findings and the indication for MRI. Subjects and methods: This study included 50 patients, their ages ranged from 18- 70 years. MRI examination included conventional sequences and dynamic series. Morphological features and dynamic parameters were recorded with classification of the findings according to BI-RADS. The findings of each modality were correlated with histopathological results. Results: BIRADS 2, 3 were considered as benign lesions and BIRADS 4, 5 were considered as malignant. There were 17 benign lesions (34 %) and 33 malignant lesions (66 %). DCE-MRI proved to have sensitivity of 100 %, specificity of 70.6 %, PPV of 86.8 %, NPV of 100 % and accuracy of 90.0 %. Conclusion: Our study results indicate that DCE-MRI has high sensitivity and moderate specificity in differentiation between benign and malignant breast lesions.

The present study was carried out on 215 women, who were suffering from the signs and symptoms of vaginitis. They attended Tikrit Teaching Hospital and private clinic in Tikrit city during the period from 1st of February 2013 to the end of January 2014, their age ranged between 15-49 years. Sixty five healthy persons were included in this study as a control group. Specimen included in present study was high vaginal swab. Identification of bacteria and yeast isolates were done by using wet mount preparation, Gram staining, cultural technique, biochemical tests, Api system and polymerase chain reaction technique. One hundred 46.5% patients were with yeast vaginitis from 215 patients, 18 (8.37%) patients were with bacterial vaginosis (BV) associated Gardnerella vaginalis and 84 (39.0%) patients were with aerobic vaginitis (AV), statistical differences were significant (p < 0.05).
