The reaction of 2, 4, 6-trihydroxyactophenonemonohydrate with hydrazine monohydrate was realized under reflux in methanol and a few drops of glacial acetic acid were added to give the (intermediate) 2-(1-hydrazono-ethyl)-benzene-1, 3, 5-triol, which reacted with salicylaldehyde in methanol to give a new type (NO) ligand [HL][(2-1-[(2-hydroxy-benzyliidene)-hydrazono]-ethyl) benzene-1, 3, 5-triol. The ligand was reacted with Mcl.(where M-Co, Ni, Cu, and Zn) under reflux in methanol with (l: 1) ratio to give complexes of the general formula [M (HL)]. All compounds have been characterized by spectroscopic methods I" H NMR, IR. UV-Vis, HPLC, atomic absorption] microanalysis along with conductivity measurement. From the above data the proposed molecular structure for| Co (IIL)],[Cu (H; L.)
Schizophrenia (SZ) is severe mental disorder and characterized by fundamental disturbances in thinking, perception and emotions. Immune deregulation has been postulated to be one of the mechanisms underlying the pathogenesis of schizophrenia. This study hypothesized that interleukins would have a link with schizophrenia patients. The serum IL-2 and IL-10 levels were examined by enzyme-linked immunosorbent assay (ELISA) in schizophrenia patients (n=60) and healthy controls (n = 30). The results showed that serum IL-2 and IL-10 levels were significantly different among schizophrenia patients. The observations indicate a significant decrease (P < 0.05) in schizophrenic patients serum levels of IL-2 compared with healthy control. Whereas

cancer inciude (18 cases in stages I & II and 12 cases in III – stage). All the patients
were suffered from urinary tract infection ( UTI) . The mean age is (57.33± 5.02)
years range ( 45-63) years, as cases and controls Patients with prostate cancer were

Background: All medical colleges give students courses in epidemiology and biostatistics to help them in understanding medical data and to prepare them to conduct graduate and professional research. After graduation, understanding and correct application of the principles of epidemiology and biostatistics help the physicians in making better diagnostic and management decision based on best evidence.
Patients and Methods: A cross-sectional questionnaire-based survey was carried out among junior (chronic resident) doctors at several hospitals in Baghdad from the 1st of January till the 31st October 2009. A total of 212 physicians answered the questionnaire which covered demographic characteristics, average score
In this paper, we will introduce a new concept of operators in b-Hilbert space, which is respected to self- adjoint operator and positive operator. Moreover we will show some of their properties as well as the relation between them.
Background :
To study the incidence of premature uterine contraction (PUC) with bacterial vaginosis (BV) in Ramadi city and to correlate the incidence of (PUC) with severity
(grades of BV).
Patients and Methods:
A prospective study was performed involving 250 women who consecutively attended Gynecological ward in Maternity and Child Hospital. 150 women were
control groups (without uterine contraction), and 100 women were regarded as patients group (with uterine contraction) at 28-34 weeks of gestation. BV was
diagnosed on the basis of four diagnostic criteria; vaginal pH>4.7, homogenous vaginal discharge, a positive Whiff test, and the presence of clue cells.
Results:
A total of 250 high vag
The problem of research is that there are ways to protect and sustain environmentally important sites in Iraq. There are no documentary sources for these sites, such as the natural landscape of natural and important natural resources, which suffer from severe environmental neglect
Background: Laparoscopic cholecystectomy
has become the standard of care for the
elective management of cholelithiasis. Little
information exists, however, regarding the
appropriateness of this procedure in the setting
of acute symptomatology.
Objective: This study was designed to
evaluate the outcome of laparoscopic
cholecystectomy in acute and severe acute
cholecystitis based on early and late biliary
complications, their incidence and
management, and conversion rates to open
surgery.
Methods: A prospective study done between
April 2007 and November 2010, in the
department of general surgery, medical city
teaching hospital, Baghdad. Includes patients
with acute cholecystitis admitted f
The physical and morphological characteristics of porous silicon (PS) synthesized via gas sensor was assessed by electrochemical etching for a Si wafer in diluted HF acid in water (1:4) at different etching times and different currents. The morphology for PS wafers by AFM show that the average pore diameter varies from 48.63 to 72.54 nm with increasing etching time from 5 to 15min and from 72.54 to 51.37nm with increasing current from 10 to 30 mA. From the study, it was found that the gas sensitivity of In2O3: CdO semiconductor, against NO2 gas, directly correlated to the nanoparticles size, and its sensitivity increases with increasing operating temperature.
In this research, the use of natural materials like wool and cannabis as intermediate reinforcement for prosthetic limbs due to their comfort, affordability, and local availability was discussed. As part of this study on below-the-knee (BK) prosthetic sockets, two sets of samples were made using a vacuum method. These sets were made of natural fiber-reinforced polymer composites with lamination 80:20: group (Y) had 4 perlon, 1 wool 4 perlon, and group (G) had 4 perlon, 1 cannabis 4 perlon. The two groups were compared with a socket made of polypropylene. Tensile testing was used to determine the mechanical characteristics of the socket materials. The Y group has a yield stress of 17 MPs, an ultimate strength of 18.75 MPa, and an elastic

Show MoreEndoglucanase produced from Aspergillus flavus was purified by several steps including precipitation with 25 % ammonium sulphate followed by Ion –exchange chromatography, the obtained specific activity was 377.35 U/ mg protein, with a yield of 51.32 % .This step was followed by gel filtration chromatography (Sepharose -6B), when a value of specific activity was 400 U/ mg protein, with a yield of 48 %. Certain properties of this purified enzyme were investigated, the optimum pH of activity was 7 and the pH of its stability was 4.5, while the temperature stability was 40 °C for 60 min. The enzyme retained 100% of its original activity after incubation at 40 °C for 60 min; the optimum temperature for enzyme activity was 40 °C.
