Biological Study of protease produced by clinical isolates of Staphylococcus aureus
...Show More Authors

The bacterial isolates were obtained from Al-Kindi Hospital were diagnosed by the Vitek-2 system and re confirm by 16srRNA gene as S. aurous, the results were shown 20 isolates (66.7%) out of 30 isolates were positive to protease production. All bacterial isolates (100%) were sensitive to Gentamicin and Levofloxacin. but resistant (100%) to aztreonam. The best temperature for enzyme production from bacteria was 37 °C, and the best pH for enzyme production was 7. Partial purification of the bacterial enzyme (protease) was carried out using short steps included ammonium sulfate 65% saturation, ion exchange using DEAE- cellulose column and then applied on gel filtration chromatography using Sephadex G-200 column. The enzymatic activity was determined for each purification step. The specific fold and yield of the purified enzyme were 5.91 and 38.3 % respectively. The molecular weight of the purified enzyme was 37 kDa , it was determined by SDS-PAGE. After being exposed to high concentrations of the protease enzyme (800-1000 µg/ml), the proliferation of a breast cancer cell line (MCF-7) was seen to be suppressed, however the inhibitory effect gradually diminished as the concentration of the enzyme decreased. 200–400 µg/ml is the recommended concentration.

The effectiveness of limited flap design in surgical removal of fully impacted lower third molars: a comparative clinical study
...Show More Authors

Introduction: Surgical removal of impacted lower wisdom teeth is one of the most commonly performed proce- dures in oral and maxillofacial surgery. Objectives: This study aimed to compare the operative and post-operative outcomes of 2 flap designs (limited vs. extended 2-sided flap) in surgical extractions of lower third molars (M3) regarding fully impacted teeth. Material and methods: A prospective, randomized, controlled split-mouth trial was designed, and included 27 patients with bilateral (symmetrically positioned) impacted M3. Limited 2-sided flap was performed on one side (group 1) and extended 2-sided flap on the other side (group 2). The effect of flap design on intra-operative (visibility, accessibility, and duration of surgery) a

Processing the Extracted Tooth to Graft the Fresh Socket (Split Mouth Prospective Clinical Study)
...Show More Authors

Background: The dimensional change of alveolar ridge is normal effect of teeth extraction, with unfavourable functional and esthetical outcomes that might jeopardize implant placement. To reduce the biological effects of the dimensional changes of alveolar ridge, various surgical procedures have been recommended, called alveolar ridge preservation. In the previous decade, autogenously teeth have been proposed as bone graft substitution in fresh extraction socket with successful results, yet with various preparation protocols. Aim: Evaluate the formation of new bone derived from the freshly extracted teeth that are grafted immediately in the post extraction sockets, in comparison with sockets without graft filling, by using CBCT and to compa

Study of the biological activity and total antioxidant content of complexes derived from sulfonic acid and 4-hydroxybenzaldehyde
...Show More Authors

The new liganed Schiff base named [(E)-3-hydroxy-4-((3,4,5- trimethoxybenzylidene)amino) naphthalene-1- sulfonic acid] was synthesized from 3,4,5-trimethoxybenzyldehyde and 1-amino-2-aphthol-4- sulfonic acid in equal molar ratio. A series of new metal complexes' of the common molecular formulation [M(L)2(H2O)2].H2O are synthesized and characterized by IR, UV–Vis spectra, mass spectra, atomic absorption, elemental analyses, chloride content, magnetic susceptibility and conductivity measurements as well as thermo gravimetric analysis (TGA, DSC). Consistent with results of the magnetic and spectral studies, the advised geometrical structures for all of the prepared complexes have been octahedral formula

Synthesis and Characterization of Some New Azo Dyes Derivatives Via Chalcone and Study Some of Their Biological Activity
...Show More Authors

This work includes synthesis of new six membered heterocyclic rings with effective amino group using the reaction of benzylideneacetophenone (chalcone) (1) with thiourea or urea in alcoholic basic medium to form: 1,3-thiazen-2-amine (2), and 1,3-oxazin-2-amine (8) respectively. The diazotization reaction was carried out with sodium nitrite in presence of hydrochloric acid to form diazonium salts which suffered coupling reaction with naphthols and phenols in the presence of sodium hydroxide to form colored azo dyes (4-7, and 10-13). o-methylation reaction of compounds (7) and (10) yielded : 1,3-thiazin -2-yl-diazenyl (14), and 1,3-oxazin-2-yl-diazenyl (15) respectively.The new compounds were characterized using vario

A study of some Biological Aspects of Procellio scaber(Isopoda : porcellionidae) Latrellile 1804In Al-jadriyia region /Baghdad-Iraq
...Show More Authors

A study of some biological aspects of the crustacean Isopod procellio scaber was carried out for the period April 2003 to march 2004 . The study consisted reproductive and morphological characteristies such as size , weight and length of the body . The result showed that the highest population density of P. scaber was 1120 individual/m2 in September 2003 and less density 403 ind/m2 in February 2004. The density was generally high in Spring and Autumn, low in Summer and Winter months.An increase of the sexual ratio appear in the females number compared to males number (p < 0.05) during most of year. Present study showed non significant increase in the length and dry weight for females compared to males in most of year months. There wer
