The effect of environment on the changes in calmodulin in rat brain produced by repeated amphetamine treatment
No full textRats were given repeated infusions of i.v. amphetamine in association with placement in a novel test environment, a protocol that produces behavioral sensitization, or in the home cage, a protocol that fails to induce sensitization. In several brain areas amphetamine altered calmodulin content, but only in the group treated in a novel environment, suggesting that amphetamine-induced alterations in calmodulin may occur only when drug treatments induce behavioral sensitization
Environmental context and drug history modulate amphetamine-induced C-FOS mRNA expression in the basal ganglia, central extended amygdala and associated limbic forebrain
No full textThe context in which amphetamine is administered modulates its ability to induce both behavioral sensitization and immediate early gene expression. When given in a novel test environment amphetamine produces greater levels of c-fos and arc mRNA expression in many brain regions relative to when it is given in the home cage. The purpose of the current study was to determine if environment and drug history interact to influence amphetamine-induced c-fos mRNA expression. Rats with a unilateral 6-hydroxydopamine lesion were treated for 7 days with saline or 0.5 mg/kg of d-amphetamine (i.v.) in a distinct and relatively novel test environment (Novel), or in their home cage (Home). Following a 10-12-day withdrawal period, a challenge injection of either saline or 0.5 mg/kg d-amphetamine was administered. In situ hybridization histochemistry was used to examine c-fos mRNA expression in several regions of the basal ganglia, the central extended amygdala, and limbic forebrain. In most brain regions amphetamine given in the Novel environment produced greater c-fos mRNA expression than when given it was given at Home, and drug history had no effect on amphetamine-induced c-fos mRNA expression. However, within the subthalamic nucleus, substantia nigra reticulata, and central nucleus of the amygdala prior experience with amphetamine in the Novel but not Home environment enhanced the effect of an amphetamine challenge injection on c-fos mRNA expression. In contrast, there was a decrease in c-fos mRNA expression in amphetamine-pretreated animals, regardless of environmental context, in the ventral portion of the far caudal striatum. Reexposure to an environment previously paired with amphetamine produced a conditioned increase in c-fos mRNA expression in portions of the caudate-putamen, the subthalamic nucleus, the nucleus accumbens shell and a conditioned decrease in c-fos mRNA expression in the central nucleus of the amygdala. We conclude that environmental context and drug history interact to alter the basal ganglia and central extended amygdala circuitry engaged by subsequent exposure to amphetamine, or exposure to an environment previously paired with amphetamine.

Decreased performance of rainbow trout Oncorhynchus mykiss emergence behaviors following embryonic exposure to benzo (z) pyrene. Fishery Bulletin, 88(3), 551-555.The sublethal effects induced by a model carcinogen and environmental contaminant on salmonid emergence behaviors have been studied. Rainbow trout embryos were exposed for 24 hours to 25 IAg/mL of benzo[a)pyrene 1 week prior to hatching. Exposures occurred during the late organogenesis period of development and allowed assessment of how a single embryonic exposure might affect emergence behaviors nearly 6 weeks later. Though no differences in numbers of alevins successfully emerging were observed, a significant decrease was noted in performance of the upstream orientation behaviors characteristic ofemergence among wild individuals.These findings are discussed in terms ofa model describing the role of upstream swimming behavior after emergence

Resistance of Kansas Sclerotinia homoeocarpa isolates to thiophanate-methyl and determination of associated β-tubulin mutation

to Thiophanate-Methyl and Determination of Associated β-Tubulin Mutation. Plant Health Progress, 15(2), 23-27.
https://doi.org/10.1094/PHP-RS-13-0120.Eighty-two isolates of Sclerotinia homoeocarpa from 12 sites in Kansas were evaluated for in vitro sensitivity to the methyl benzimidazole carbamate (MBC) fungicide thiophanate-methyl at the discriminatory dose of 10 μg/ml. Seventeen isolates were sensitive to thiophanate-methyl and the remaining isolates were resistant. Of the 65 isolates from golf course putting greens, two isolates were sensitive and the remaining 63 isolates were resistant. Six resistant and five sensitive isolates were also evaluated in greenhouse assays on fungicide-treated plants. The isolates that were sensitive to thiophanate-methyl in vitro did not cause any disease on thiophanate-methyl-treated plants, and those that were resistant in vitro caused blighting on treated plants equivalent to the nontreated controls. The entire β-tubulin gene was sequenced for four resistant and four sensitive isolates. The resistant isolates all harbored a substitution of alanine for glutamic acid at codon 198 (E198A). These results provide a starting point for further surveys and monitoring of fungicide sensitivity
Whole genome analysis of the Lupo Italiano
No full textThe Lupo Italiano (Italian Wolfdog) is a domestic dog (Canis lupus familiaris) breed created in 1966 by crossing of Apennine grey wolves (Canis lupus italicus) to German Shepherd dogs (GSD). The breed has an official studbook with management protocols, under the control of the Ministry of Agriculture. The breed is characterized by strength, resistance, and strong capabilities in learning, as well as participation in search and rescue activities. Considering the depth and completeness of genealogical information, the high levels of inbreeding, and the presence of the wolf as a recent ancestor, the Lupo Italiano can be used as a model to investigate the effects of population structure and selection on wolf-dog hybridization. The aim of this work is to compare the genetic background of the Italian Wolfdog with that of the GSD, village dogs, grey wolves from the Apennines, and other dog populations, with a specific goal of detailing introgression between the Lupo Italiano, wolf and GSD. Three hundred and seventy-seven individuals were genotyped using a high density chip containing more than 170K SNPs. Genotypes for Lupo Italiano were provided by University of Milano and National Institutes of Health in Bethesda, MD. Those for the Apennine wolves were produced by ISPRA, and those for GSD, village dogs and grey wolves were publicly available (Dryad, Shannon et al. 2015). Samples and loci were quality checked, and then analyzed using Multi-Dimensional Scaling (MDS). The relationship matrix based on pedigrees was compared with the genomic relationship matrix (GRM), calculated using GCTA64 software. In addition, the genomic heterozygosity-based inbreeding coefficient has been estimated using PLINK v1.9 software. Reynolds distances were computed to define the relationships among the five populations. In addition, the Lupo Italiano, wolves and GSD were studied at the chromosomal level. As expected, the closest population to the Lupo Italiano is the German Shepherd dog (Reynold genetic distance 0.25), whereas the farthest is the Apennine Wolf (0.40). Results are expected to provide a clear picture of the genomic structure of the Lupo Italiano and its hybridization history. Beside scientific interest, these findings will allow the breeder association (AAALI) to better manage their animals and conserve breed genetic variation
The Revolution Mislaid: Socialism and the Trade Unions Revisited
No full text William M. Dick, Labor and Socialism in America: the Gompers Era Kennikat Press, 1972, pp. 211 Both Marx and Engels were convinced that America, in the Gilded Age, was riper for socialism than any European nation. Marx wrote in 1879 that the United States "have at present overtaken England in the rapidity of economical progress . . . the masses are quicker, and have greater political means in their hands, to resent the form of a progress accom- plished at their expense/' Engels wrote in 1886 that ". . . the advancing waves are becoming more powerful, the set-backs less paralyzing. . . . Once the Americans get started it will be with an energy and volume compared with which we in Europe shall be mere children." </jats:p
