background urinary tract infections (uti) caused by resistant bacteria are becoming more prevalent. the spread of extended-spectrum beta-lactamase (esbl)-producing bacteria worldwide has become a serious public health issue among healthcare centers and in the community. drugs and many secondary metabolites from medicinal plants have proved to be economical and effective against many pathogens. ...
sclerotinia sclerotiorum is a phytopathogenicfungus that attacks more than 400 plant species of them medicinal plant. in this study the extract obtained from basal stalk rot of helianthus annuus l., attacked by s. sclerotiorum, was subjected to the analysis of ftir to identify the presence of beta-glucan. ft-ir spectrum showed four ranges of bands in 890 cm-1, two overlap band in 1047 and 1078 ...
Antibiotic resistant ?-lactamases are diverse and complex enzymes produced by most of the Gram-negative bacteria that mediated number plasmids. The impact these has posed a major threat to health sectors challenged available treatment options for both community hospital acquired infections. These include uncomplicated severe life-threatening Moreover, with resistance cephalosporin drugs MDR str...
BACKGROUND The aims of this study were to confirm the presence of OmpK35 and OmpK36 in extended-spectrum beta-lactamase-producing and nonextended-spectrum beta-lactamase-producing Klebsiella pneumoniae and to determine the relationship between porin expression and resistance to third-generation cephalosporins. METHODS Fifty-two K. pneumoniae isolates were obtained and analyzed for extended-sp...
Background and purpose: Beta-thalassemia is an autosomal recessive disease characterized by reduction or complete absence of beta-globin gene expression. This study aimed to find out and determine the spectrum of beta-globin gene mutations and especially rare mutation in beta-carrier couple in Babolsar, north region of Iran. This is very important in perinatal diagnosis of thalassemia. Materia...
Let $E$ be the self-similar set generated by {\it iterated function system} {\[ f_0(x)=\frac{x}{\beta},\quad f_1(x)=\frac{x+1}{\beta}, \quad f_{\beta+1}=\frac{x+\beta+1}{\beta} \]}with $\beta\ge 3$. {Then} is a with complete {overlaps}, i.e., $f_{0}\circ f_{\beta+1}=f_{1}\circ f_1$, but not totally self-similar. We investigate all its generating systems, give spectrum of $E$, and determine Haus...
Background and purpose: Extended Spectrum Beta Lactamases (ESBLs) are one of the most important health care issues all over the world. Uropathogenesis are responsible for life threatening infections in children. In this study we aimed at investigating the epidemiology of CTX, TEM and VEB genes in pediatric UTI. Materials and methods: Urine samples were collected during six months in Sari Bou...
