Candida ģints sēņu jutības pret antifungālajiem līdzekļiem noteikšana

2015

Bakalaura darbs tika izstrādāts LU Medicīnas fakultātē Mg. Sc. biol. Ivetas Līdumas vadībā. Bakalaura darbā ir analizēta Mikobakterioloģiskajā laboratorijā identificēto no klīniskajiem paraugiem izdalīto raugveida sēņu dati, ka arī pētīta sēņu paraugu jutība, pret antifungālajiem līdzekļiem (amfotericīnu B, itrakonazolu, flukonazolu). Sēņu sugas tika identificētas izmantojot mikroskopisko analīzi, ka arī veicot uzsējumus uz BBL™ CHROMagar™ barotnes. Lai noteiktu antifungālo jutību tika izmantota standartizēta disku difūzijas metode, izmantojot CLSI noteiktos kritērijus, kā arī lietojot E-testus tika noteikta MIC (minimālā inhibējošā koncentrācija). Jutība pret antifungālajiem līdzekļiem tik…

Hyperspectral UAV-Imagery and photogrammetric canopy height model in estimating forest stand variables

2017

Remote sensing using unmanned aerial vehicle (UAV) -borne sensors is currently a highly interesting approach for the estimation of forest characteristics. 3D remote sensing data from airborne laser scanning or digital stereo photogrammetry enable highly accurate estimation of forest variables related to the volume of growing stock and dimension of the trees, whereas recognition of tree species dominance and proportion of different tree species has been a major complication in remote sensing-based estimation of stand variables. In this study the use of UAV-borne hyperspectral imagery was examined in combination with a high-resolution photogrammetric canopy height model in estimating forest v…

Cartelization process in institutionalized environments: legitimation and political communication

2017

International audience; The main objective of this paper is to analyze cartel party tendencies toward professionalization of communicative institutional processes (Mair, 015).The main role of the media in a audience democracy is indisputable (Manin, 1998). So the media politics are one of the main features of public space. In this way, Political parties have become platforms of placement of their leaders to occupy the largest number of institutional positions. Consequently, this phenomenon has spread as a common practice of our political system. The emergence of partisan elite, which has professionalized itself in high political-institutional positions, has colonized the leadership of publi…

Confronto tra attività catalitica e fotocatalitica dell’eteropoliacido di Keggin H3PW12O40 supportato su ossidi o su nanotubi di carbonio

2015

Catalytic and catalytic photo-assisted dehydration of 2-propanol to form propene in gas-solid regime at atmospheric pressure and 80°C was carried out by using a Keggin heteropolyacid H3PW12O40 (PW12) supported on different oxides. Binary materials have been prepared by impregnation of PW12 on different commercial and home prepared supports (TiO2, SiO2 or carbon nanotubes). The supported Keggin PW12 species played a key role both for the catalytic and the photo-assisted catalytic reactions, due to their strong acidity and ability to form strong oxidant species under UV irradiation, respectively. The contemporary presence of heat and UV light improved the activity of almost all POM supported …

High level of intrinsic phenotypic antimicrobial resistance in enterobacteria from terrestrial wildlife in Gabonese national parks.

2021

Data on the prevalence of antibiotic resistance in Enterobacteriaceae in African wildlife are still relatively limited. The aim of this study was to estimate the prevalence of phenotypic intrinsic and acquired antimicrobial resistance of enterobacteria from several species of terrestrial wild mammals in national parks of Gabon. Colony culture and isolation were done using MacConkey agar. Isolates were identified using the VITEK 2 and MALDI-TOF methods. Antibiotic susceptibility was analysed and interpreted according to the European Committee on Antimicrobial Susceptibility Testing guidelines. The preliminary test for ESBL-producing Enterobacteriaceae was performed by replicating enterobacte…

Amperometric detection of extended-spectrum β-lactamase activity : application to the characterization of resistant E.coli strains

2015

EA MERS CT3; International audience; The amperometric detection of extended-spectrum β-lactamase (ESBL) with carbon screen-printed sensors was investigated in the presence of the Nitrocefin, a commercially-available β-lactamase chromogenic cephalosporin substrate. Using an ESBL isolated from a clinical sample, it was shown for the first time that the intensity of a specific anodic pic current (EP = [similar]+0.3 V vs. Ag/AgCl) resulting from the catalytic hydrolysis of the β-lactam ring was proportional to the amount of ESBL. The proof-of-principle of a novel susceptibility assay for the rapid and accurate identification of ESBL- producing bacteria was then demonstrated. The detection schem…

On the relaxation mechanisms of 6-azauracil

2011

The nonadiabatic photochemistry of 6-azauracil has been studied by means of the CASPT2//CASSCF protocol and double-ζ plus polarization ANO basis sets. Minimum energy states, transition states, minimum energy paths, and surface intersections have been computed in order to obtain an accurate description of several potential energy hypersurfaces. It is concluded that, after absorption of ultraviolet radiation (248 nm), two main relaxation mechanisms may occur, via which the lowest (3)(ππ*) state can be populated. The first one takes place via a conical intersection involving the bright (1)(ππ*) and the lowest (1)(nπ*) states, ((1)ππ*/(1)nπ*)(CI), from which a low-energy singlet-triplet crossin…
