Introdução: As cepas de Staphylococcus aureus resistente a meticilina (MRSA) apresentam resistência todos os antimicrobianos da classe dos betalactâmicos. A do MRSA é controlada pelo gene mecA. Até 2011, haviam sido identificados oito tipos SCCmec. Os I, II e III são associados isolados hospitalares, IV V estirpes comunidade. pode ainda apresentar aos macrolídeos, mediada erm (erythromycin ribo...

objective anti-rh d igg is used for the prevention of anti-d antibody production in rh- individuals who have been exposed to rh+ red blood cells. the stability of igg preparations as a solution is low, with a shelf life of a year or more. formulation of anti-rh d igg as a lyophilized preparation would decrease its degradation rate and increases its shelf life. the objective of this study was to...

background: it is now well established that several environmental stress factors cause activation of p38 map kinase and jnk in various cell types to produce chemokines. objective: to investigate the expression of cxc chemokines gro/kc and sdf- 1a in rat's h4 hepatoma cells in response to heat shock, hyperosmolarity and oxidative stress. methods: hepatoma cells were maintained in mem medium...

BACKGROUND Neonatal sepsis is a blood stream infection which is seen in the first month of life of the neonate. Bacterial profile of neonatal septicemia is constantly changing thus, current knowledge on the patterns of bacterial isolates, its antibiotic resistance profile, and associated factors, are essential to design and implement appropriate interventions. Therefore, the aim of this study w...

background: methicillin resistant staphylococcus aureus (mrsa) is a common major human pathogen that causes hospital-acquired infections. characterization and typing of the staphylococcal cassette chromosome has led to a better understanding of mrsa infection cycle in hospital. the meca-associated hypervariable region size classifies mrsa isolates that colonized in nasal carriers. objectives: t...

Background and Objective: The S100B protein has recently been considered as an important marker for predicting severe brain damage; however there has been very little evidence of increasing this marker in cerebral edema due to metabolic disorders such as diabetes ketoacidosis (DKA). This study was designed and performed to evaluate the prognostic role of S100B protein in predicting brain edema ...

to evaluate symbiotic effectiveness and salt tolerance of sinorhizobium meliloti strains, 50 rhizobial strains were isolated from root nodules of medicago sativa cultivated in tehran and zanjan fields. under n-free conditions, the symbiotic effectiveness of different sinorhizobium meliloti strains of bami cultivar were evaluated under greenhouse conditions using 50 sinorhizobium meliloti strain...
