the examination and explanation of swinburne’s view about the “problem of evil” and his response to it, is the main approach of this paper. in his viewpoint, in contrast with this idea, we should appeal to “theory of theodicy”. his understanding of theodicy depends on “the greater goods” and according to which evils are necessary for attaining greater goods. moreover, in this paper we'll t...

among factors causing disagreement of shiites and sunnis is commentatorial   hadiths. such hadiths are of great significance in the process of understanding as well as commenting on the quran–and even inferring juristic precepts. hence, attitude of muslims towards such   hadiths play a significant role in the process of formation of their beliefs and inferring islamic precepts. attitude of sunn...

A murine monoclonal antibody against human lysozyme (AHL MoAb) was produced and tested on normal and leukemic monocytes using flow cytometry. The antibody gave a positive reactivity on normal monocytes permeabilized by saponin (82% to 98% of positive cells) and a negative reactivity on normal permeabilized neutrophils. This monocyte-specific reactivity had not been observed using a polyclonal a...

N-Acyl homoserine lactone (AHL) serves as signaling molecule for quorum sensing (QS) in Gram-negative bacteria to regulate various physiological activities including pathogenicity. With the aim of isolating freshwater-borne bacteria that can cause outbreak of disease in plants and portrayed QS properties, environmental water sampling was conducted. Here we report the preliminary screening of AH...

Bacterial communication or quorum sensing (QS) is achieved via sensing of QS signaling molecules consisting of oligopeptides in Gram-positive bacteria and N-acyl homoserine lactones (AHL) in most Gram-negative bacteria. In this study, Enterobacteriaceae isolates from Batavia lettuce were screened for AHL production. Enterobacter asburiae, identified by matrix-assisted laser desorption ionizatio...

Bacteria communicate by producing quorum sensing molecules called autoinducers, which include autoinducer-1, an N-hexanoyl homoserine lactone (AHL), and autoinducer-2. Bacteria present in the human oral cavity have been shown to produce autoinducer-2, but not AHL. Here, we report the isolation of two AHL-producing Klebsiella pneumoniae strains from the posterior dorsal surface of the tongue of ...

N-acylhomoserine lactone (AHL)-mediated quorum-sensing (QS) regulates virulence functions in plant and animal pathogens such as Agrobacterium tumefaciens and Pseudomonas aeruginosa. A chemolibrary of more than 3500 compounds was screened using two bacterial AHL-biosensors to identify QS-inhibitors (QSIs). The purity and structure of 15 QSIs selected through this screening were verified using HP...

Erwinia carotovora subsp. atroseptica, E. carotovora subsp. betavasculorum, and E. carotovora subsp. carotovora produce high levels of extracellular enzymes, such as pectate lyase (Pel), polygalacturonase (Peh), cellulase (Cel), and protease (Prt), and the quorum-sensing signal N-acyl-homoserine lactone (AHL) at 28 degrees C. However, the production of these enzymes and AHL by these bacteria is...

Quorum sensing (QS) in Sinorhizobium meliloti, the N-fixing bacterial symbiont of Medicago host plants, involves at least half a dozen different N-acyl homoserine lactone (AHL) signals and perhaps an equal number of AHL receptors. The accumulation of 55 proteins was found to be dependent on SinI, the AHL synthase, and/or on ExpR, one of the AHL receptors. Gas chromatography-mass spectrometry an...
