By this way, Arabic grammatology gives importance to nouns, verbs, Huroufs and compound nouns and expressions. this science explained relationships existed between these elements as predicate. This paper aims to analyze theses foundations and to examine relationships from contemporary linguistic view. 2018-12-01T00:00:00Z http://dspace.centre-univ-mila.dz/jspui/handle/123456789/4061 Titre: Anticoagulant Activities of Centaurea macrocephala L. Auteur(s): Sara , HIMOUR , BELATTARHakima Résumé: Our study is based on the biological activities of the plant Centaurea macrocephala L., from the Mechtat Seraghna in the wilaya of Mila (Algeria).This work consists to study the anticoagulant activity of the extracts of the seeds and leaves of Centaurea macrocephala L., obtained by maceration in the solvent of ethanol. The extraction yield showed values between31% for the leaves and 25% for the seeds. The anticoagulant activity was evaluated by the testof prothrombin levels (TP) and the blood of a normal man, the results obtained indicate avery important anticoagulant activity of the two extracts on the exogenous pathway of coagulation (TQ of 47,26 s in the leaves and 29,23s for the seeds). 2022-06-01T00:00:00Z http://dspace.centre-univ-mila.dz/jspui/handle/123456789/4060 Titre: Antioxidant activities of Hypochaeris laevigata var. hipponensis: Endemic species from Algeria Auteur(s): Hakima, BELATTAR Résumé: Hypochaeris laevigata var. hipponensis (Asteraceae) is an endemic plant from Algeria. In the current study, we analyzed for the first time the antioxidant activities by five methods (β-Carotene bleaching test, DPPH test, ABTS radical cation reduction test, CUPRAC test, Ferrous ions chelating test) of three fractions of aerial part of plant: dichloromethane (DCM), ethyl acetate (EA) and n-butanol (BuOH). We also determined the total phenolic and flavonoid contents. The fraction EA showed the highest values, followed by BuOH and DCM fractions. Furthermore, the antioxidant action was dictated by five methods and the tested plant fractions demonstrated a noteworthy antioxidant action 2022-06-01T00:00:00Z http://dspace.centre-univ-mila.dz/jspui/handle/123456789/4059 Titre: Antibiotic resistance profile of Escherichia Coli isolated from patients with urinary tract infections Auteur(s): Sabri , BOUSBIA, BOUCHAREB, Noureddine Résumé: Urinary tract infections (UTIs) are among the most common bacterial infections whether they are community or hospital acquired. Several risk factors are associated with UTIs, such as, amongothers, sex, previous UTIs, vaginal infections, and genetic susceptibility. In the present study, weanalyzed the resistance profile of Escherichia coli which is the bacterium frequently associated with urinary tract infections. E. coli strains were isolated by culture from urine from 150 episodes of urinary tract infections. Our results showed that among the 150 episodes tested, 102 were from females (69%) and 45 were from males (31%). The antibiogram results showed that E. coli strains exhibited high resistance against ampicillin and amoxicillin because these two antibiotics are the most widely used in the medical field. Imipenem and aminoglycosides, on the other hand, remain the most active molecules. Nevertheless, it is prudent to use these antibiotics, in order to reduce the risk of developing resistance against them. 2022-06-01T00:00:00Z
