we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
background and objectives:infection of pleural fluid is a common disease and because of antibiotic administration, the microbiology of this fluid has changed. the aim of this study was to determine the common bacteria and suitable antibiotics for treatment in pleural effusion (pe). materials and methods: in this cross sectional study, 1210 samples with exudative features were cultured for poss...
despite recent innovations in the laboratory diagnosis of bacterial from nonbacterial meningitis, solid data-necessary for early determination of bacterial meningitis (bm) before organism growth in the culture medium-are missing. therefore cerebrospinal fluid (csf) lactate levels were evaluated as a possible means of differentiating the two clinical entities. this was a retrospective study. pat...
now-a-days graphic design plays a major role in influencing culture, society, business, and customers, in such a way that one could look upon every individual as a potential customer. graphic designers seek to identify customers needs and find an intelligent solution for them. correct identification and understanding of those needs is the first step towards achieving ones goals. marketing knowh...
Bacterial sepsis and septic shock result from the overproduction of inflammatory mediators as a consequence of the interaction of the immune system with bacteria and bacterial wall constituents in the body. Bacterial cell wall constituents such as lipopolysaccharide, peptidoglycans, and lipoteichoic acid are particularly responsible for the deleterious effects of bacteria. These constituents in...
Abstract It was shown that several pathogenic bacterial effector proteins contain the Glu-Pro-Ile-Tyr-Ala (EPIYA) or a similar sequence. These bacterial EPIYA effectors are delivered into host cell via type III or IV secretion system, where they undergo tyrosine phosphorylation at the EPIYA sequences, which triggers interaction with multiple host cell SH2 domain-containing proteins and thereby...
The blood-cerebrospinal fluid barrier physiologically protects the meningeal spaces from blood-borne bacterial pathogens, due to the existence of specialized junctional interendothelial complexes. Few bacterial pathogens are able to reach the subarachnoidal space and among those, Neisseria meningitidis is the one that achieves this task the most constantly when present in the bloodstream. Menin...
n Antibiotics are essential in the prevention and cure of bacterial infections. n The use of antibiotics generates resistance to their effects, reducing their effectiveness in the prevention and cure of disease. n Resistance is associated with antibiotic usage (appropriate or otherwise), and the interaction of microorganisms, people and the environment. n Resistance is therefore not eradicable,...
