Beta-Lactam Antibiotics and Vancomycin Beta-lactam antibiotics
Anti-bacterial drugs have “selective toxicity”, that is they interact with a target present on the bacterial cell, the prokaryote, that is not present in the mammalian host, the eukaryote. For the ß-lactam drugs, this target is the cell wall. Mammalian cells lack cell walls, which for the bacteria are a critically important barrier protecting the organism from not only the vagaries of osmotic s...
متن کاملThe Survey of Genes Encoding Beta-Lactamases, in Escherichia Coli Resistant to Beta-Lactam and Non-Beta-Lactam Antibiotics
Objective(s) Resistance to the new generation of cephalosporins which is mediated by Extended-Spectrum beta-lactamases (ESBLs) has been found among Escherichia coli isolates throughout the world. These resistance genes and their producers, the micro-organisms carrying beta-lactamases, are responsible for serious clinical and therapeutic problems among inpatients and it is necessary to pay more...

In this paper, we introduce the notion of fuzzy dot PS-subalgebras in PSalgebras and establish its various properties.
متن کاملA NEW NOTION OF FUZZY PS-COMPACTNESS
In this paper, using pre-semi-open L-sets and their inequality, a new notion of PS-compactness is introduced in L-topological spaces, where L is a complete De Morgan algebra. This notion does not depend on the structure of the basis lattice L and L does not need any distributivity.
