Human cytomegalovirus (CMV) infection is associated with higher risk of cardiovascular diseases in immunocompromised organ transplant patients; it has been linked with the elevated arterial blood pressure. This study aimed to find a relationship between CMV antibody titers and blood pressure elevation by using the enzyme-linked immunosorbent assay (ELISA) to measure CMV IgG levels in the serum of 60 patients with high blood pressure, in comparison to 30 healthy persons with normal blood pressure as a control. All patients and control were 25-50 years old. The results showed that CMV antibody titers were higher in those who undergo blood pressure elevation. This finding supports the hypothesis that; the common CMV infection may leads to i

Coef (r) (0.9988), recovery (98.32 %), Erel (-1.68 %) aqueous - to- organic phase ratio (5:4) and the mole-ratio method approved the [AuBr4]-1 : RAN as being 1:1 .
Around fifty Escherichia coli isolates were isolated from sixty midstream urine specimens collected from patients visiting hospitals in Baghdad city. Approximately, 52% of all isolates were identified as extended spectrum beta lactamases (ESBL) producer. Results demonstrated that 92% of these isolates were sensitive to carbapenems. Only four β-lactamase coding genes were detected; blaTEM, blaPER, blaVIM and blaCTX-M-2. As a conclusion, this work revealed that local E. coli isolates harboured ESBL coding genes which may contribute in its pathogenicity.
Spectroscopic studies, in the ultraviolet region were carried out to characterize the
binding of isolated AFP with its labeled antibody in human malignant germ cell ovarian
tumor homogenates. Factors affecting the absorption properties of AFP, and the complex
of isolated AFP with the labeled antibody such as pH, solvent polarity (solvent
perturbation technique), spectrophotometric pH titration and thermal stability in the
presence of different concentration of sodium chloride have been studied. The
spectroscopic pH titration curves for human AFP and for the complex of isolated AFP
with the labeled antibody gave pka of 5.7 and 7.3 for histidine residue, respectively,

Show MoreIn this paper, we present a concept of nC- symmetric operator as follows: Let A be a bounded linear operator on separable complex Hilbert space , the operator A is said to be nC-symmetric if there exists a positive number n (n such that CAn = A*ⁿ C (An = C A*ⁿ C). We provide an example and study the basic properties of this class of operators. Finally, we attempt to describe the relation between nC-symmetric operator and some other operators such as Fredholm and self-adjoint operators.

The electric quadrupole moments for some nitrogen isotopes (12,14,15,16,18N) are
studied by shell model calculations with the proton-neutron formalism. Theoretical
calculations performed using the different set of effective charges due to the core
polarization effect. The effective charges in the p-shell nuclei are found to be
slightly different from those in the sd-shell nuclei. Most of the results we have
obtained are underestimated with the measured data for the isotopes considered in
this work.

Both stress and strength are assumed to have an Inverse Lomax distribution with unknown shape parameters and a common known scale parameter. The increase and decrease in the real values of the two reliabilities are studied according to the increase and decrease in the distribution parameters. Two estimation methods are used to estimate the distribution parameters and the reliabilities, which are Maximum Likelihood and Regression. A comparison is made between the estimators based on a simulation study by the mean squared error criteria, which revealed that the maximum likelihood estimator works the best.
