Toxin-antitoxin (TA) modules are ubiquitous molecular switches controlling bacterial growth via the release of toxins that inhibit cell proliferation. Most of these toxins interfere with protein translation, but a growing variety of other mechanisms hints at a diversity that is not yet fully appreciated. Here, we characterize a group of FIC domain proteins as toxins of the conserved and abundan...

Abstract Dissolved and particulate sodium, magnesium calcium are analyzed in ice cores to determine past changes sea extent, terrestrial dust variability atmospheric aerosol transport efficiency. They also used date if annual layers visible. Multiple methods have been developed analyze these important compounds cores. Continuous flow analysis (CFA) is implemented with instruments that sample th...

This study evaluated the occurrence of an enhancing inhibitory effect of the combined application of Origanum vulgare L. essential oil and acetic acid against Staphylococcus aureus by the determination of Fractional Inhibitory Concentration (FIC) index and kill-time assay in nutrient broth, meat broth and in a food model (meat pieces). Acetic acid showed MIC and MFC of 0.6 and 1.25 μL.mL(-1), r...

Peppermint with antiseptic and known healing properties is a plant from the Labiatae family. In this study, we analyzed the chemical composition of essential oil from the flowering aerial part of peppermint by GC and GC/MS. Its antimicrobial activity was evaluated against bacteria, fungi and yeast by micro broth dilution assay. The fractional inhibitory concentration (FIC) and FIC Index (FICI) ...

A selectively ion-implanted collector (SIC) is implemented in a 0.8 um BiCMOS process to improve the RF characteristics of the BJT devices. The SIC BJT device has better ft and fmax than the FIC (fully ion-implanted collector) BJT device because the extrinsic base-collector capacitance is reduced by the SIC process. The fmax is 9.5GHz and ft is 7.8 GHz for the SIC BJT device while the fmax is 7...

Fractal image compression technique which excludes the similarities between different regions of the image takes long time for encoding. An artificial intelligence technique like neural network is used to reduce the search space and encoding time for the MRI images with an algorithm called as back propagation neural network algorithm. Initially, MRI image is divided into ranges and domains of f...

In this communication, the ciprofloxacin-trimethoprim (Cp-Tm) combination showed synergistic (Fractional Inhibitory Concentration, FIC index 0.399) and additive (FIC index 0.665-0.83) effects against Vibrio cholerae O1 biotype El Tor serotype Ogawa isolates having Cp MICs 10 microg/ml and Cp 0.66 microg/ml, respectively, following agar dilution checkerboard method. The time-kill study results d...

Combining extensional rheology with in-situ synchrotron ultrafast x-ray scattering, we studied flow-induced phase behaviors of polyethylene (PE) in a wide temperature range up to 240 °C. Non-equilibrium phase diagrams of crystallization and melting under flow conditions are constructed in stress-temperature space, composing of melt, non-crystalline δ, hexagonal and orthorhombic phases. The non-...

conclusions our findings indicate that probiotic bacterial strains of lactobacillus have a significant inhibitory effect on the growth of p. aeruginosa ptcc 1430. the antimicrobial potency of this combination can be useful for designing and developing alternative therapeutic strategies against p. aeruginosa infections. results the results showed a significant effect of cfs on the growth of p. a...
