The discovery and study of toxin-antitoxin (TA) systems helps us advance our understanding of the strategies prokaryotes employ to regulate cellular processes related to the general stress response, such as defense against phages, growth control, biofilm formation, persistence, and programmed cell death. Here we identify and characterize a TA system found in various bacteria, including the glob...

Abstract: Aim We investigate the length-weight relationship estimates of seventeen species caught using an artisanal purse seine in Abrolhos Bank, a tropical estuarine complex eastern Brazil. Methods From February 2012 to November 2013, fish were collected monthly small with total 84 landings. The captured mangrove margins during high tide and retrieved after six hours at depths ranging from 1....

Vibrio parahaemolyticus belongs to an expanding group of aquatic pathogens that are widely distributed in environments. This species is a lethal pathogen for number economically important marine crabs. However, studies exploring host–vibrio interactions between V. and crabs scarce, therefore, the underlying molecular mechanisms unclear. Herein, we performed comprehensive proteomic analysis inve...

Background An Australian study including 4433 children found that delayed Diphtheria-Tetanus-acellular Pertussis–containing vaccination was associated with reduced risk of developing atopic dermatitis (AD) before age 1 year. Objective We assessed whether against diphtheria, tetanus, acellular pertussis, polio, and Haemophilus influenzae type b (Diphtheria, Tetanus, Pertussis – Inactivated Polio...

In vitro studies were performed to characterize [3H]cocaine binding to dark and light ethnic hair types. In vitro binding to hair was selective, was reversible and increased linearly with increasing hair concentration. Scatchard analyses revealed high-affinity (6-112 nM) and low-affinity (906-4433 nM) binding in hair. Competition studies demonstrated that the potencies of 3beta-(4-bromophenyl)t...

The term “illegal price manipulation” is difficult to define. Current U.S. law does not explicitly define it. The finance and economics literature uses the term “manipulation” in an imprecise manner. This paper proposes that a trading strategy not be classified as “illegal price manipulation” unless the violator’s intent is to pursue a scheme that undermines economic efficiency both by making p...
