Immunohistochemical Coexpression of VEGF and CD34 in Ameloblastoma
...Show More Authors

Background:
Angiogenic potential m most tumors; characterized by VEGF and vascular bed density around tumor islands, is believed to be an important marker in predicting tumor growth,
recurrence and metastasis.
Materials and Methods:
The study included 50 cases of ameloblastomas. From each case 4 μm sections were stained IHC with antivascular endothelial growth factor antibody- and endothelial lined
vessels anti CD34 antibody to evaluate their expression and intensity in relation to their Fac Med Baghdad clinicopathological features.
Results:
Generally, VEGF was significantly highly expressed with strong intensity in outer cell layer of tumor islands, and the newly formed blood vessels were significantly
predominantly rounded and small in size in comparison to dental folicale and papilla of tooth germ. Young aged patients (≤ 20yrs) had highest mean MvD around tumor islands
(35.9). Regarding WHO classification; follicular, plexiform and lining cells in UAB had higher expression then acanthomatous and types, but 67% of those in plexiform were of
moderate intensity. There was no significant differences in mean MvD in all histological solid subtypes, and characterized by round and small vessels. Except those in plexiform,
they were elongated and medium. UAB had significant lower microvessel count around lining tumor cells (but not around mural growth) and more percentage of elongated medium
sized vessels than follicular but less than plexiform. There was significant correlation between VEGF expression and the shape of microvessels. Considering different
morphological cellular pattern, basal cells showed the highest VEGF positivity and intensity (87.5).
Conclusions:
The present study indicate the usefulness of the VEGF expression and MvD in explaining the aggressive, locally invasive biological behavior of ameloblastoma. The high
angiogenic potential is enhancing tumor cell survival and the increase in the production of new blood vessels formation is facilitating tumor growth, and by time will enhance the
proliferation potential of the incompletely removed surviving tumor islands, so increasing the chance of ameloblastoma recurrence.

Preparation and in-Vitro Evaluation of Mucoadhesive Clotrimazole Vaginal Hydrogel
...Show More Authors

Clotrimazole (CLO) is an antimycotic imidazole derivative applied locally for the treatment of vaginal yeast infections. In this study, CLO was formulated as vaginal mucoadhesive hydrogel, using different types of mucoadhesive polymers to ensure prolonged contact between active ingredient and vaginal mucosa.

Physicochemical properties of the prepared formulas were evaluated as a visual inspection, pH, swelling index, spreadability, and mucoadhesive characteristics, in addition to an in-vitro drug release. The influence of type and concentration of polymers as CMC-Na (1.5, 2.5, and 3.5%w/w), carbopol 940( 0.25, 0.5, and 1 %w/w) and poloxamer 407 (15, 25, 30%w/w) on CLO release  from the prepared gels were also invest

Kinetic-spectrophotometric estimation of tetracycline in bulk and pharmaceutical forms
...Show More Authors

Simple and sensitive spectrophotometric method is described based on the coupling reaction of tetracycline hydrochloride (TC. HCl) with diazotized 4-aminopyridine in bulk and pharmaceutical forms. Colored azo dye formed during this reaction is measured at 433 nm as a function of time. Factors affecting the reaction yield were studied and the conditions were optimized. The kinetic study involves initial rate and fixed time (10 minutes) procedures for constructing the calibration graphs to determine the concentration of (TC. HCl). The graphs were linear for both methods in concentration range of 10.0 to 100.0 μg.mL-1. The recommended procedure was applied successfully in the determination of (TC. HCl) in its commercial formulations.

In vitro isolation and expansion of neural stem cells NSCs
...Show More Authors

   Neural stem cells (NSCs) are progenitor cells which have the ability to self‑renewal and potential for differentiating into neurons, oligodendrocytes, and astrocytes. The in vitro isolation, culturing, identification, cryopreservation were investigated to produce neural stem cells in culture as successful sources for further studies before using it for clinical trials. In this study, mouse bone marrow was the source of neural stem cells. The results of morphological study and immunocytochemistry of isolated cells showed that NSCs can be produced successfully and maintaining their self‑renewal and successfully forming neurosphere for multiple passages. The spheres preserved their morphology in culture and cryopreserved t

Investigation and Study of Photonic Current Rate in Bremsstrahlung process
...Show More Authors

In this paper, we investigate and study quantum theoretical of quark-gluon interaction modeling in QGP matter formatted. In theoretical modeling, we can use a flavor number, strength coupling, critical energy Tc = 190 MeV, system energy (400-650)MeV, fugacity of quark and gluon, and photon energy in range of 1-10 GeV parameter to calculation and investigation spectrum of photon rate. We calculation and study the photon rate produced through bremsstrahlung processes from the stable QGP matter. The photon rate production from cg → dgy systems at bremsstrahlung processes are found to be increased with increased fugacity, decreased strength coupling, decreased the photons energy and temperature of system. The photons rate in cg → dgy is inc

Estimation and Simulation in Batch Fermentation of Baker's Yeast Production
...Show More Authors

Baker's Yeast is an important additive among the substances, which improves bred quality, thus, a consideration has been made to study the conditions and parameters that affecting the production of the yeast in a batch fermenter experimentally and theoretically. Experimental runs were implemented in a 12-liter pilot-scale fermenter to predict the rate of growth and other parameters such as amount of additive consumed and the amount of heat generated. The process is modeled and performed using a computer programming prepped for this purpose, the model gave a good agreement comparing to the experimental work specially in the log phase.
