Candida antarctica Lipase A-Based Enantiorecognition of a Highly Strained 4-Dibenzocyclooctynol (DIBO) Used for PET Imaging
2020
The enantiomers of aromatic 4-dibenzocyclooctynol (DIBO), used for radiolabeling and subsequent conjugation of biomolecules to form radioligands for positron emission tomography (PET), were separated by kinetic resolution using lipase A from Candida antarctica (CAL-A). In optimized conditions, (R)-DIBO [(R)-1, ee 95%] and its acetylated (S)-ester [(S)-2, ee 96%] were isolated. In silico docking results explained the ability of CAL-A to differentiate the enantiomers of DIBO and to accommodate various acyl donors. Anhydrous MgCl2 was used for binding water from the reaction medium and, thus, for obtaining higher conversion by preventing hydrolysis of the product (S)-2 into the starting materi…

Evaluation of CandiSelect4, a new chromogenic medium for isolation and presumptive identification of Candida species from clinical specimens
2008
Abstract In clinical laboratories, isolation of Candida species is generally based on the culture of specimens on Sabouraud dextrose agar. This strategy does not allow species identification on primary culture and makes it difficult to detect mixed cultures. Chromogenic media contain substrates that react specifically with different Candida species, and partly overcome these difficulties. Objectives The aim of this study was to compare two chromogenic media: (i) CandiSelect4 (C4), a new medium developed for direct identification of C. albicans and presumptive identification of C. krusei , C. tropicalis and C. glabrata (ii) CHROMagar Candida (CH), a medium licensed for direct identification …
Bovine lactoferrin prevents invasive fungal infections in very low birth weight infants: a randomized controlled trial.
2011
Background: Lactoferrin is a mammalian milk glycoprotein involved in innate immunity. Recent data show that bovine lactoferrin (bLF) prevents late-onset sepsis in preterm very low birth weight (VLBW) neonates. Methods: This is a secondary analysis of data from a multicenter randomized controlled trial where preterm VLBW neonates randomly received bLF (100 mg/day; group A1), bLF + Lactobacillus rhamnosus GG (106 colony-forming units per day; group A2), or placebo (group B) for 6 weeks. Here we analyze the incidence rates of fungal colonization, invasive fungal infection (IFI), and rate of progression from colonization to infection in all groups. Results: This study included 472 neonates who…
The nature of black stains in Lascaux Cave, France, as revealed by surface-enhanced Raman spectroscopy
2011
We used surface-enhanced Raman spectroscopy to investigate the chemical composition of the black stains threatening the rock-art paintings of Lascaux Cave, Montignac, France. The stains are mainly composed of melanin from the fungus Ochroconis sp. and the faecal pellets of the collembolan Folsomia candida. Surface-enhanced Raman spectroscopy is a useful technique for revealing the structure of unknown macromolecules in cultural heritage research. Copyright © 2011 John Wiley & Sons, Ltd.

Lēmumu pieņemšana politiskajās partijās Latvijā: kandidātu sarakstu veidošana 12. Saeimas vēlēšanām
2018
Bakalaura darba tēma ir „Lēmumu pieņemšana politiskajās partijās Latvijā: kandidātu sarakstu veidošana 12. Saeimas vēlēšanām”. Darba autore pēc vēlēšanās startējošo politisko partiju un partiju apvienību biedru iesaistes iespējām kandidātu sarakstu veidošanā 12. Saeimas vēlēšanām noteica demokrātiskumu šajā lēmumu pieņemšanas aspektā. Lai noteiktu kandidātu sarakstu veidošanas demokrātiskumu, tika aptaujāti 39 partiju un partiju apvienību pārstāvji. Iegūtās atbildes tikai apstrādātas pēc autores izstrādātās metodoloģijas. Izvirzītā hipotēze neapstiprinās. Kandidātu sarakstu veidošana 12. Saeimas vēlēšanām neklasificējas kā ļoti nedemokrātiska. Secināts, ka kandidātu iespēja tikt ierindotiem…
Genome-wide mapping of signatures of selection using a high-density array identified candidate genes for growth traits and local adaptation in chicke…
2023
Abstract Background Availability of single nucleotide polymorphism (SNP) genotyping arrays and progress in statistical analyses have allowed the identification of genomic regions and genes under selection in chicken. In this study, SNP data from the 600 K Affymetrix chicken array were used to detect signatures of selection in 23 local Italian chicken populations. The populations were categorized into four groups for comparative analysis based on live weight (heavy vs light) and geographical area (Northern vs Southern Italy). Putative signatures of selection were investigated by combining three extended haplotype homozygosity (EHH) statistical approaches to quantify excess of haplotype homoz…
Privatister – hvem er de, og hva motiverer dem til å lykkes på eksamen? Kartlegging av bakgrunnsvariabler og deres intensjon i lys av en utvidet vers…
2016
Det finnes fa empiriske studier i Norge som kartlegger bakgrunnsvariabler av privatister og undersoker motivasjonsprosesser ved bruk av teoretisk tilnaerming. Hensikten med denne studien er todelt. Det forste malet er a kartlegge ulike sider ved privatistenes bakgrunn, i lys av aldersmessig sammensetting, kjonnsfordeling, antall pameldte eksamener, tidligere erfaring med privatistordningen, grunnene for a ta eksamen, privatistenes tilrettelegging av eksamen pa grunn av saerskilte behov, tidligere kontakt med PPT, og normativ pavirkning. Det andre malet er en teoretisk tilnaerming med fokus pa intensjonelle prosesser i lys av utvidet teori om planlagt atferd (TPB). Resultatene viser at priva…
The global challenge of Candida auris in the intensive care unit
2019
Since the first isolation of Candida auris in 2009, scientific community has witnessed an exponential emergence of infection episodes and outbreaks in different world regions. It is hard to predict future C. auris diffusion. By now, global surveillance, improving knowledge, and taking care of the A.U.R.I.S. major issues may be the best ways to face C. auris challenge
