b ackg r oun d : pseudomonas aeruginosa is one of the most important oppor- tunistic pathogens responsible for various types of infections. children suffer significant morbidity and mortality due to nosocomial infections. the aim of this study was to investigate the presence of class1 integron, blabel, blaper, blakpc, blavim, blaimp and blaoxagroup-1  genes among p. aeruginosa isolates at child...

<b><i>Introduction:</i></b> Acute kidney injury (AKI) is a frequent complication among patients in the intensive care unit (ICU). The limitations of serum Cr (sCr) timely detecting AKI are well known. Beta-trace protein (BTP) emerging as novel endogenous glomerular filtration rate marker. aim this study was to explore role BTP marker AKI. <b><i>Methods:</i...

background brucellosis is an important cosmopolitan infection disease caused by organisms belonging to the genus brucella. the cgt gene (cyclic β-1, 2 glucan transporter gene) is a virulent factor in brucella genus. the present study was conducted with the aim of cloning and expression of brucella cgt gene. materials and methods brucella melitensis cgt gene was amplified from extracted chromoso...

Beta thalassemia major is an inherited disease resulting from reduction or total lack of beta globin chains. Patients with this disease need repeated blood transfusion for survival. This may cause oxidative stress and tissue injury due to iron overload, altered antioxidant enzymes, and other essential trace element levels. The aim of this review is to scrutinize the relationship between oxidati...

conclusions the most common qnr gene was qnrb, and none of the isolates carried qnra or qepa. the aac (6’)-ib-cr variant was the most prevalent pmqr gene, and it was associated with the prevalence of ciprofloxacin resistance in our esbl-producing isolates. results of the 123 isolates, 103 (83.73%) had one of the five pmqr genes, including 83 (83.83%) of the 99 e. coli strains and 20 (86.95%) of...

Background: Malignant melanoma is the most aggressive form of skin cancer. In contrast to other tumors, the role of estrogen in the initiation and progression of melanoma remains unclear. The aim of this study was to evaluate estrogen receptor beta protein expression in human melanoma tissues and in the benign melanocytic lesions. Method: Twenty-one patients, 11 with cutaneous melanoma and 10 w...

Hypertension and diabetes are clinical conditions which contribute to the development of chronic kidney disease as well as risk factors for cardiovascular events. In recent years, lipocalin-type-prostaglandin-D-synthase (beta trace protein; BTP) has increasingly been studied as an alternative to creatinine for the evaluation of renal function as well as for being a possible biomarker for cardio...

Matrix-variate beta distributions are applied in different fields of hypothesis testing, multivariate correlation analysis, zero regression, canonical correlation analysis and etc. A methodology is proposed to generate matrix-variate beta generator distributions by combining the matrix-variate beta kernel with an unknown function of the trace operator. Several statistical characteristics, exten...
