Genetic variation in the primary sex ratio in populations of the intertidal copepod, Tigriopus californicus, is widespread on Vancouver Island.
2011
Hypothesis: Genetic variation for the primary sex ratio is widespread in a copepodwith polygenic sex determination. Cytoplasmic sex ratio distorters (e.g. Wolbachia andmicrosporidians) influence the primary sex ratio in this copepod. Organism: The intertidal copepod, Tigriopus californicus; six populations from VancouverIsland, British Columbia. Study site: Quantitative genetics experiment in the laboratory. PCR and antibioticsexperiment to test for the presence of cytoplasmic sex ratio distorters. Results: Genetic variation for the primary sex ratio was found in five of the six populationssurveyed. The primary sex ratio was paternally transmitted. There was no evidence thatWolbachia or mic…
Moringa olifeira Lam. Stimulates Activation of the Insulin-Dependent Akt Pathway. Antidiabetic Effect in a Diet-Induced Obesity (DIO) Mouse Model.
2017
International audience; We investigated the antidiabetic effect of Moringa olifeira Lam. in a diet-induced obesity (DIO) mouse model. Six mice were randomly selected as normal controls. Moringa olifeira Lam. leaf extract at a dose of 200, 400 or 600 mg/kg body weight, glibenclamide (Glib) at the dose of 10 mg/kg (positive control) and distilled water at 10 ml/kg (control group) were administered orally by gastric intubation, and each group consisted of six mice. Insulinsensitive tissues (liver, skeletal muscle) were collected to investigate antidiabetic effects and examine the plant's molecular mechanisms. Moringa olifeira Lam. leaf extract prevented weight gain. It also reduced blood gluco…

Candida albicans-epithelial interactions: dissecting the roles of active penetration, induced endocytosis and host factors on the infection process
2012
International audience; Candida albicans frequently causes superficial infections by invading and damaging epithelial cells, but may also cause systemic infections by penetrating through epithelial barriers. C. albicans is a remarkable pathogen because it can invade epithelial cells via two distinct mechanisms: induced endocytosis, analogous to facultative intracellular enteropathogenic bacteria, and active penetration, similar to plant pathogenic fungi. Here we investigated the contributions of the two invasion routes of C. albicans to epithelial invasion. Using selective cellular inhibition approaches and differential fluorescence microscopy, we demonstrate that induced endocytosis contri…

Administrative Capacity as a Constraint to Fiscal Decentralization. The Case of Romania and Poland
2020
This paper considers the problem of administrative capacity as one of the main requirements that the accession countries seeking EU membership had to meet, and as a prerequisite to the decentralization of their public sectors and public finances. The selected decentralization problems are analyzed using the cases of two countries: Romania and Poland. The results of a theoretical and practical evaluation of administrative capacity as a likely obstacle to fiscal decentralization are presented taking account of the different levels of decentralization in Poland and Romania. A comparative analysis of Romania and Poland shows that administrative capacity can be a constraint for fiscal decentrali…
Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) differ in their suitability as hosts for the endangered freshwater pearl mussel (Margari…
2017
1. European populations of the freshwater pearl mussel (FPM, Margaritifera margaritifera) have widely collapsed, and despite many types of conservation actions the number of successful restoration trials has remained limited. The goal of this study was to find new aspects for the conservation by investigating whether there are population-specific differences in suitability of Atlantic salmon (Salmo salar) and brown trout (S. trutta) as the hosts for the parasitic glochidium larvae of FPM, depending probably on the historical occurrence of these salmonid species in FPM habitats. 2. We studied the potential host specificity both in the field and in laboratory by exposing salmonid fish to FPM …
La costituzionalizzazione del principio di sussidiarietà orizzontale e la risposta dei cittadini. Il caso della proposta di regolamento per la collab…
2022
ll presente articolo ha a oggetto l’evoluzione del principio di sussidiarietà orizzontale e verrà articolato secondo l’ordine esplicativo che segue. Nello specifico si darà sinteticamente atto del contesto politico-normativo che ha indotto il legislatore costituzionale nel 2001 a introdurre l’attuale testo dell’art. 118 della Costituzione italiana. A dispetto dell’attenzione del legislatore verso il principio di sussidiarietà verticale, minore fu il dibattito circa il profilo orizzontale (anche detto sociale). Per lungo tempo il principio sancito al comma 4 dell’art. 118 è rimasto pressoché inattuato. Tuttavia, il contesto sociale e normativo lascia emerge nuovi spazi di valorizzazione e at…
Acetylcholinesterase activity in juvenileCiona intestinalis(Ascidiacea, Urochordata) after exposure to tributyltin
2012
The acetylcholinesterase (AChE) activity has been studied in 4-day post-fertilization juveniles of Ciona intestinalis exposed to tributyltin (TBT) at 10-5 M using the histochemical method of Karnovsky and Roots. Relative to vertebrate tissues and organs, the development of adult form of ascidians is interesting, because the analysis of many nuclear genes indicated that the ascidians are the closest living relatives of the vertebrates. Therefore, toxicity research using different approaches could provide data for comparative studies with vertebrates. AChE is over-expressed under chemical stress and in some diseases of vertebrates. Therefore, AChE is considered a biomarker of environmental co…
Cilvēka zarnu mikrobioma salīdzinājums pacientiem ar dažādu 2.tipa cukura diabēta ilgumu un terapiju veidiem
2021
Maģistra darba izstrādes laikā iegūti rezultāti par zarnu mikrobioma taksonomiskā sastāva atšķirībām 270 pacientos ar 2. tipa cukura diabēta (T2D) diagnozi, bet atšķirīgu tā ilgumu kopš diagnosticēšanas brīža un pielietotajām antidiabētiskajām terapijām. Darba mērķis bija noskaidrot, kā šīm T2D pacientu apakšgrupām atšķiras zarnu mikrobioma taksonomiskais profils. Mikrobiālajai DNS, kas iegūta no fēču paraugiem, tika veikta visa metagenoma analīze ar lielapjoma paralēlo sekvenēšanu. Darba rezultāti apstiprināja vairākas zināmas asociācijas starp dažādām antidiabētiskajām terapijām un cilvēka zarnu mikrobiomu, kā arī iegūti jauni dati par zarnu mikrobioma taksonomiskajām atšķirībām indivīdos…
