In this study the effects of Fe2O3 and Fe3O4 magnetic nanoparticles and EDTA on urease activity was investigated. The effect of nano-Fe2O3 and nano-Fe3O4 on urease activity were investigated. Urease activity was studies by UV-Vis spectrophotometry at 40 °C at pH = 7.2 using sodium phosphate as buffer. Measurements were carried out using 0.075 mg/ml of urease and a range of nano-Fe2O3 and nano-F...
there is strong evidence that two cerebral hemispheres are differentially involved in emotional memory and that amygdala is a key subcortical structure for emotional experience. the present research investigated the possible involvement of lateralization of basolateral amygdala (bla) and central amygdala (cea) in place avoidance memory. for this purpose, male long-evans rats (280-320 g) were im...
x-chromosome inactivation (xci) is a process by which one of the copies of the x chromosome in mammalian female cells is inactivated. the xci causes a balanced x-linked gene quantity between male and females; moreover, it results mosaic females which have paternal active x in some cells and maternal active x in others. cellular mosaicism is a noteworthy phenomenon and lowers the risk of x-linke...
Introduction: The basolateral amygdala (BLA) and infralimbic area (IL) of the medial prefrontal cortex (mPFC) are two interconnected brain structures that mediate both fear memory expression and extinction. Besides the well-known role of the BLA in the acquisition and expression of fear memory, projections from IL to BLA inhibit fear expression and have a critical role in fear extinction. Howev...
• The introduction of solar light to Fe(VI)/PMS process improved E. coli inactivation. Fe(VI)/PMS/solar system has good potentials for micropollutants’ removal. low amounts oxidants and wide operational pH makes its application possible. bacterial inactivation pathways were proposed system. In this work, the effect as a “reducing agent” in disinfection decontamination water was investigated. Si...
Background and Aims: Despite the screening of blood donors, blood transfusion represents an ideal port of entry for blood-borne infection. Blood-borne pathogen transmission has been a concern since the earliest days of transfusion. The blood product of platelet (PLT) concentrates is still faced with the risk of bacterial and viral contaminations. Pathogen inactivation technologies offer a proac...
in this study response surface methodology was used to optimize process conditions and to evaluate the effect of ultrasound on quality attributes (antioxidant activity, ph, total soluble solid, turbidity) and the inactivation of escherichia coli bacteria in carrot juice. independent variables in this study were temperature (25-50°c), time (20-40 min) and frequency (0-130 khz). in this study the...
background: biofilm infections are a major challenge in medical practice. bacteria that live in a biofilm phenotype are more resistant to both antimicrobial therapy and host immune responses compared to their planktonic counterparts. so, there is need for new therapeutic strategies to combat these infections. a promising approach [known as photodynamic inactivation (pdi)] to kill bacteria growi...
