A simple, environmentally benign, sustainable, accurate and cost effective green approach has been developed for the determination of Acrylamide (2-propenamide) in different samples of potato chips collected from the Iraqi market during the year 2012 and a traditional Iraqi meal called Harissa. The method entails a straightforward de-fatting practice with n-hexane, extraction with lukewarm water, and cleanup with solid-phase extraction (SPE) cartridges containing the sorbent bed of the mixed mode ion exchangers (SiliaPrep C8/SCX-2/SAX). The final extracts are directly determined by liquid chromatography-Ultra violet (LC-UV) at a wavelength of 205nm for quantification. The acrylamide content in the examined potato chips were in the range 339–1024 μg/kg, while for Harissa sample it was 235 μg/kg. The recoveries were in the range of 97.4 and 101.2% with relative standard deviations (RSD%) of about 4.1%. The limit of detection (LOD) and the limit of quantification (LOQ) were 20 μg/kg and 50 μg/kg in the basis of signal to noise ratios of 3:1 and 9:1, respectively. The green goal of the proposed method was accomplished by developing a procedure that uses minimal amounts of benign reagents and the avoidance of producing toxic residues. This method can be used for routine analysis of Acrylamide in any fatty food matrices.
This work aimed to investigate the effect of Diode laser 805 nm on plasmid DNA and RNA
contents of some Gram negative bacteria represented by Escherichia coli and Proteus mirabilis isolates
.Plasmid extraction was done using two methods (Salting out and CTAB method).Different powers and
pulse repetition rates for 805 nm Diode Laser were used to study this effect. Results revealed that the
plasmid profile of the two species were highly affected using (2, 3) W at different frequencies including
5and 10 kHz as compared with 1 kHz while plasmids were gradually disappeared at 1W, 10 kHz. In the
same time the shining of RNA was also decreased gradually then disappeared with increasing powers
especially at 2W and 10 kHz cau
A simple, environmental friendly and selective sample preparation technique employing porous membrane protected micro-solid phase extraction (μ-SPE) loaded with molecularly imprinted polymer (MIP) for the determination of ochratoxin A (OTA) is described. After the extraction, the analyte was desorbed using ultrasonication and was analyzed using high performance liquid chromatography. Under the optimized conditions, the detection limits of OTA for coffee, grape juice and urine were 0.06 ng g−1, 0.02 and 0.02 ng mL−1, respectively while the quantification limits were 0.19 ng g−1, 0.06 and 0.08 ng mL−1, respectively. The recoveries of OTA from coffee spiked at 1, 25 and 50 ng g−1, grape juice and urine samples at 1, 25 and 50 ng mL

Show MoreUnsaturated soil can raise many geotechnical problems upon wetting and drying resulting in swelling upon wetting and collapsing (shrinkage) in drying and changing in the soil shear strength. The classical principles of saturated soil are often not suitable in explaining these phenomena. In this study, expansive soil (bentonite and sand) were tested in different water contents and dry unit weight chosen from the compaction curve to examine the effect of water content change on soil properties (swelling pressure, expansion index, shear strength (soil cohesion) and soil suction by the filter paper method). The physical properties of these soils were studied by conducting series of tests in laboratory. Fitting methods

It has been assumed that the localization of parasite in the urethra may be responsible for the recurrence of vaginal infection.
Aim: To evaluate the infection rate of urethral trichomoniasis and to evaluate two different laboratory’ methods used in the diagnosis.
Methods: The present study consisted of420female patients presented with vaginal discharge with or without itching or disorient, investigated for urethral trichomoniasis who were compared to 50 females represented the control group.

Background: Thrombocytopenia is the second most common hematological abnormality in pregnancy following anemia. However, its incidence causes and outcomes received scarce attention, particularly in developing countries like Iraq.
Objective: This study was conducted to determine the incidence, causes and consequences of thrombocytopenia on both the mother and fetus.
Material and Methods: Platelet counts were performed on 600 pregnant women in their third trimester and on 200 age matched non pregnant healthy women, as well as 150 of the newborns of the former groups.
Results: The overall incidence of thrombocytopenia in pregnancy was 8.6%, with the gestational thrombocytopenia implicated in 76.9%,. Hy

The mutated BRAF protein activates MAPK signaling pathway, results in abnormal cellular growth, apoptosis resistance, tumor progression and metastasis. Pan-BRAF is one of available BRAF monoclonal antibodies and shared by both the wild and mutant BRAF.BRAF status is mostly determined by DNA sequencing methods. In this investigation we assessed the monoclonal Pan BRAF specific antibody that can identify wild and mutant type proteins together in formalin-fixed paraffin-embedded thyroid tumor tissues by Immunohistochemistry (IHC).

In this study, TEC calculation was performed over Baghdad city, Iraq, using a combination of two numerical methods called composite Simpson and composite Trapezoidal methods. TEC was calculated using the line integral of the electron density derived from the International reference ionosphere IRI2012 and NeQuick2 models from 70 to 2000 km above the earth surface. The hour of the day and the day number of the year, R12, were chosen as inputs for the calculation techniques to take into account latitudinal, diurnal and seasonal variation of TEC. The results of latitudinal variation of TE
