The Efficiency of Terpenes Extracts of Eucalyptus Camaldulensis Seed to control Larval Stage of Callosobruchus maculates (Coleoptera:Bruchidae)
No full textThe current study has beenconduced to evaluate the effect of extracted crude terpens at the concentrations of 6,8% of seeds of Eucalyptuscamaldulensison the 4th larval instar oftheCallosobruchusmaculates and the percentage of the cowpea seed germination.The Results showed that the terpens extract of the concentration of 8% increases the mortality rate of the fourth larval instar and it reach to 63.3%, and then decrease of to 26.6,20% at concentration of 6%and forcontrol treatment respectively The percentage of adult emergence reduces to 0% at the concentration of 8% compared with control treatment in which it reach to 66.6%. The extraction atbothconcentrations 6,8% does not affect the germination rat
Evaluation of Air Pollution Tolerance Index (APTI) by two species of terrestrial plants in some stations within Babylon Province, Iraq
Full text linkThis study deals with air pollution tolerance index (APTI) and anatomical variation in leaves of two species of terrestrial plants Ficus sp. and Conocarpus sp. that have bee commonly the separated along roadsides in many stations within Babylon province. APTI values of both species were less than 10 during study period which represented sensitivity of these plants to air pollution. There are Anatomical responses to pollution in the leaves of both studied species. Main adaptations included increased thickness of parenchyma cell walls with clear dark deposits in sections of Ficus sp. from sections of stations 2 and 4 which represent polluted stations. Conocarpus sp. main adaptation included stomata increased in density and decreased in size with high tannin cells content in heavy polluted station
The Innovative Method for Vaccine Preparation Against Multidrug Resistant and Virulence Acinetobacter baumannii Iraqi Isolates
Full text linkThe expanding of the medically important diseases created by multidrug-resistant Acinetobacter baumannii warrants the evolve a new methodology for prevention includes vaccination and treatment. Totally of forty-five clinical isolates identified as A.baumannii were obtained from hospitalized patients from three hospital in Baghdad City during the period from February 2016 to August 2016. Followed by diagnosing using different methods. Every strain was tested for susceptibility testing also some important virulence factorswere detected. Two isolates were chosen for the immunization and vaccine model, the first one remittent for most antibiotics except one are too virulence (strong) and the second is less virulent and resistance (weak).Enzyme-linked immunosorbent assaywas used for assessments of Toll like receptor 4,and Toll like receptor 2 concentrations in mouse serum at 14, 21 and 28 days of immunization. Results proved that the strong isolate showed resistance to all antibiotics except one and positive to all virulence factors except one, while the weak isolate resistance to Ceftriaxone, Cefotaxime, positive to tow virulence factors. Mice were intramuscular inoculated with strong and weak isolate. There are high significant differences when using strong A.baumannii strong in the level of TLR4 and there was not an important variation among the use of strong and weak isolation in the level of TLR2.Finaly,the yield refers to the TLR4 plays a key role in innate sensing with multidrug resistance isolate immunization, whereas TLR 2 shows it gives the same level of stimulation during immunization with both strains but lesser concentration than TLR4, so the inactivated with MDR isolate has a potential for development as a candidate vaccine for strong protection against MDR isolate infections

ويتضح من خلال نتائج الدراسة أن تركيز اليورانيوم في محافظة المثنى هو الأعلى ثم ذي قار والبصرة والنجف وكربلاء و واسط وبابل وأخيرا بغداد .The study of determing concentration uranium in samples of female teeth. Concentrations of uranium has measured in this study for (10) samples of female teeth distributed on the some of middle and south governorate of Iraq (Muthana – Dekar – Basrah – Najaf – Karbalah – Waset – Babel – Baghdad) .
The uranium concentration in teeth samples measured by using fission tracks registration in (CR-39) track detector that caused by the bombardment of (U) with thermal neutrons from (Am-Be) neutron source that has flux of (5x103n.cm-2s-1).
The concentrations values were calculated by a compartion with standard samples. The results that the uranium concentrations in female teeth are(0.022) ,(0.038) ,(0.056) , (0.089),(0.15),(0.15),(0.169),(0.17) Pmm respectively. As a conclusion from the study of uranium concentration in Muthana governorate is higher than Dekar and Basrah , Najaf , Karbalah, Waset , Babel and last Baghdad .)

Synthesis and Characterization of New Heterocyclic Thioxanthone Derivatives
Full text linkThis work comprises the synthesis of new thioxanthone derivatives containing C-substituted thioxanthone. To obtain these derivatives, the o-mercapto benzoic acid was chosen as the starting material, o-mercapto benzoic acid with phenoxy acetic acid / thio phenoxy acetic acid gave 2-(oxy acetic acid) thioxanthone (1) and 2-(thio acetic acid) thioxanthone (2) respectively. Treatment of (1,2) with thionyl chloride gave 2-(oxy acetyl chloride) thioxanthone (3) and 2-(thio acetyl chloride) thioxanthone (4) respectively. Compounds (3,4) were treated with hydrazine hydrate (99%) to form the hydrazide (5,6) which is the desired Chiron, the hydrazide (5,6) was used to react with phenyl isothiocyanate / phenyl isocyanate to give thiosemicarbazide (7,8) / semicarbazide (9,10) derivatives respectively, which were used in the preparation of eight types of heterocyclic derivatives.
