The combination has activity against many Gram-positive and Gram-negative bacteria including Pseudomonas aeruginosa. [4] It is used to treat pelvic inflammatory disease, intra-abdominal infection, pneumonia, cellulitis, and sepsis. [4] It is given by injection into a vein. [5]
Cardiac muscle histology 400x. Myocytes are incredibly specialized cells with only a select number of different organelle types. A myocyte is composed of multiple myofibrils, which contain the “contractile units” of the muscle known as a sarcomere. [3] These sarcomeres are arranged in adjacent formations along the myofibrils.
Piperacillin is a broad-spectrum β-lactam antibiotic of the ureidopenicillin class. [1] The chemical structure of piperacillin and other ureidopenicillins incorporates a polar side chain that enhances penetration into Gram-negative bacteria and reduces susceptibility to cleavage by Gram-negative beta lactamase enzymes.
The 5-HT 3 receptor antagonists suppress vomiting and nausea by inhibiting serotonin binding to the 5-HT 3 receptors. The highest concentration of 5-HT 3 receptors in the central nervous system are found in the STN and chemoreceptor trigger zone (CTZ), and 5-HT 3 antagonists may also suppress vomiting and nausea by acting at these sites.

[3] [4] The term has been extended to include a group of similar ATPases found in the cells of both striated muscle tissue and smooth muscle tissue. Following the discovery in 1973 of enzymes with myosin-like function in Acanthamoeba castellanii, a global range of divergent myosin genes have been discovered throughout the realm of eukaryotes. [5]
Reduction of the iron (Fe 3+ to Fe 2+) occurs in conjunction with this cleavage, but no FeEnt bacterial reductase enzyme has been identified, and the mechanism for this process is still unclear. [8] The reduction potential for Fe 3+ /Fe 2+ –enterobactin complex is pH dependent and varies from −0.57 V (vs NHE ) at pH 6 to −0.79 V at pH 7.4 ...
The move to drop the lawsuit was announced in a one-page court filing by both companies in a Manhattan court, where they said they will drop their claims against each other. Neither company ...
Ethylenediaminetetraacetic acid (EDTA), also called EDTA acid, is an aminopolycarboxylic acid with the formula [CH 2 N(CH 2 CO 2 H) 2] 2. This white, slightly water-soluble solid is widely used to bind to iron (Fe 2+ /Fe 3+) and calcium ions (Ca 2+), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca ...
