laboratory and field experiments were conducted to determine the efficacy of some insecticides on the control of sarta longhorned beetle, aeolesthes sarta solsky adults and larvae. in the laboratory, three pairs of mated and non-oviposited adults were released on the logs of field elm, ulmus minor mill that had been treated with chlorpyrifos, carbaryl, permethrin or imidacloprid. in the field e...

The cyclic dinucleotide 3',5'-cyclic diguanylic acid (c-di-GMP) is a naturally occurring small molecule that regulates important signaling systems in bacteria. We have recently shown that c-di-GMP inhibits Staphylococcus aureus biofilm formation in vitro and its adherence to HeLa cells. We now report that c-di-GMP treatment has an antimicrobial and antipathogenic activity in vivo and reduces, i...

BACKGROUND Conditions of low energy availability (EA) (<30 kcal/kgLBM) have been associated with suppressed metabolic hormones and reductions in LH pulsatility in previously sedentary women during short-term manipulations of energy intake (EI) and exercise energy expenditure (EEE) in a controlled laboratory setting. The purpose of this study was to examine if EA, defined as EA = (EI-EEE)/kgLBM,...

Large body size confers a reproductive advantage to adults of the wood-boring beetle Phoracantha semipunctata (F.) (Cerambycidae: Cerambycinae: Phoracanthini). Larvae of this species feed subcortically in stressed and dying eucalypt trees and logs. We evaluated the influence of the larval environment on larval performance and adult body size by manipulating the post-felling age of host logs (fr...

Aim—To compare the performance characteristics and clinical application of two diVerent technologies for quantifying serum hepatitis C virus (HCV) RNA levels. Methods—HCV RNA was quantified by Amplicor HCV Monitor assay (Amplicor) and Quantiplex HCV RNA 2.0 assay (bDNA-2) in 119 sera from 107 HCV infected patients. Results—Both assays had similar sensitivity (79.4% for Amplicor; 86.0% for bDNA2...

This article examines a set of interactions (logs) takenfrom t h e f a n of computer-mediated communicntion known as Internet Relay Chat (IRC). The authors were particularly concerned with the interaction management strategies adopted by the participants in the logs during the opening and closing phases of the interactions to d m l o p interpersonal relationships and communicate socioemotional ...
