Investigation of deltamethrin resistance in salmon lice (Lepeophtheirus salmonis) provides no evidence for roles of mutations in voltage-gated sodium…

2020

BACKGROUND The pyrethroid deltamethrin is used to treat infestations of farmed salmon by parasitic salmon lice, Lepeophtheirus salmonis (Kroyer). However, the efficacy of deltamethrin for salmon delousing is threatened by resistance development. In terrestrial arthropods, knockdown resistance (kdr) mutations of the voltage-gated sodium channel (Nav ), the molecular target for pyrethroids, can cause deltamethrin resistance. A putative kdr mutation of an L. salmonis sodium channel homologue (LsNav 1.3 I936V) has been identified previously. At the same time, deltamethrin resistance of L. salmonis has been shown to be inherited maternally and to be associated with mitochondrial DNA (mtDNA) muta…

Les actions du chlorfenprop-methyl sur l'integrite membranaire dans les mitochondries des plantes

1983

Summary The action of chlorfenprop-methyl, chlorfenprop and its cysteine conjugate was studied on potato tuber mitochondria. Chlorfenprop-methyl altered membrane structure at 250 μM. leading to a loss of membrane integrity. Chlorfenprop and its cysteine conjugate were without any significant effects. From what is known about the rapid hydrolysis of chlorfenprop-methyl in plant tissues and from the results presented in this paper, it was deduced that alteration in intra-cellular membrane integrity is not a mechanism of phytotoxic action for chlorfenprop-methyl.

Psychometric properties and validation of the sexual sensation seeking scale in Spanish adolescents: Brief screening method for use in research and c…

2018

Abstract Sexual sensation seeking among adolescents has been mostly associated with unprotected sex and other risky behaviors. This paper presents the Spanish adaptation and validation of the Sexual Sensation Seeking Scale (SSSS). This cross-sectional study included 1350 adolescents (601 male and 749 female), aged between 15 and 18 years ( M  = 16.1, SD  = 0.97). Exploratory Factor Analysis (EFA) yielded two components: Physical Sensations Attraction (PSA), and New Experiences Seeking (NES), which together accounted for 48.98% of the total variance. That structure was later verified through Confirmatory Factor Analysis (CFA). Internal consistency was 0.82 for the total scale, and 0.76 and 0…

L'efficacité des privatisations françaises : une vision dynamique à travers la théorie de la gouvernance

2004

International audience; A reading of the process of privatization through the corporate governance theory leads to propose a model taking into account, on the one hand, the time dimension of the process of privatization, on the other hand, the contextual, organizational, governance and strategic variables which influence this process. After replicating some traditional tests, we test this model on a sample of French privatized firms and on a seven years horizon. The positive effect traditionally attributed to privatizations is not confirmed. The importance of the effect is subordinated to some of the suggested variables.; Une lecture du processus de privatisation à travers la théorie de la …

Menstrual problems and lifestyle among Spanish university women

2020

Menstrual problems affect many young women worldwide, conditioning both their academic performance and quality of life. This study sought to analyse the prevalence of menstrual problems and their possible relationship with lifestyle among Spanish university women, as part of a research project (UniHcos Project) involving a cohort of 11 Spanish universities with 7208 university students. A descriptive analysis was performed using the bivariate chi-square test and the Student&rsquo

Plēsonīgo cenu jēdziens Latvijas konkurences tiesībās

2015

Plēsonīgo cenu stratēģijas realizēšana Latvijas doktrīnā līdz šim nav apskatīta. Lielākā problēma, kas saistīta ar plēsonīgajām cenām, ir plēsonīgo cenu piemērošanas nošķiršana no ikdienišķas biznesa prakses. Eiropas Savienības doktrīnā un Eiropas Savienības Tiesas praksē ir nostiprināti dažādi kritēriji, meklējot risinājumu iepriekš minētajai problēmai. Autors pētījuma gaitā analizē plēsonīgo cenu jēdzienu, kā arī Eiropas Savienības Tiesas praksi un tās piedāvātos kritērijus plēsonīgo cenu piemērošanas identificēšanai. Tāpat darba gaitā autors salīdzina Konkurences padomes nolēmumos nostiprinātos kritērijus ar Eiropas Savienības Tiesas praksi. Darbā, cita starpā, autors analizē arī Amerika…

Stable changes in CD4+ T lymphocyte miRNA expression after exposure to HIV-1

2012

Abstract MicroRNAs (miRNAs) inhibit HIV-1 expression by either modulating host innate immunity or by directly interfering with viral mRNAs. We evaluated the expression of 377 miRNAs in CD4+ T cells from HIV-1 élite long-term nonprogressors (éLTNPs), naive patients, and multiply exposed uninfected (MEU) patients, and we observed that the éLTNP patients clustered with naive patients, whereas all MEU subjects grouped together. The discriminatory power of miRNAs showed that 21 miRNAs significantly differentiated éLTNP from MEU patients and 23 miRNAs distinguished naive from MEU patients, whereas only 1 miRNA (miR-155) discriminated éLTNP from naive patients. We proposed that miRNA expression ma…

Correlation of nitric oxide and atrial natriuretic peptide changes with altered cGMP homeostasis in liver cirrhosis.

2005

: Background: Cyclic GMP (cGMP) concentration is increased in plasma of patients with liver cirrhosis. Three possible mechanisms may contribute: increased cGMP synthesis by soluble (activated by nitric oxide), or particulate (activated by atrial natriuretic peptide (ANP)) guanylate cyclase or increased release from cells. Aim: The aim of this work was to analyze the possible contributors to increased plasma cGMP and to assess whether changes in the parameters of the system vary with the degree of liver disease (Child Pugh score) or by the presence of ascites. Methods: We measured cGMP in plasma and lymphocytes, soluble guanylate cyclase activation by nitric oxide in lymphocytes, nitrates an…

Interruption of the enterohepatic circulation of phenprocoumon by cholestyramine

1977

The effect of cholestyramine (12 gm/day divided into 3 doses) on the pharmacokinetics and pharmacodynamics of a single intravenouse dose (30 mg) of phenprocoumon was studied in 6 normal subjects. Cholestyramine treatment led to an increase in the rate of elimination of phenprocoumon in all. Total clearance increased 1.5- to 2-fold. The total anticoagulant effect per dose was considerably reduced during treatment with cholestyramine. Binding studies in vitro showed that phenprocoumon is strongly bound to cholestyramine and that at a given cholestyramine concentration the percentage of phenprocoumon bound remained constant over a large concentration range of phenprocoumon. The results suggest…
