Varietal and geographic classification of french red wines in terms of pigments and flavonoid compounds
1988
Thirty-four French red wines originating from six different grape varieties and three different production areas were analysed in duplicate for 15 anthocyanins, ten flavonoids and three colour parameters, F-statistics, principal component analysis and stepwise discriminant analysis were used to identify and to explain differences among samples. Clear difference between wines made from different varieties were mainly related to anthocyanin 3-acylglucosides. Malvidin and peonidin 3-acetylglucosides were found in increasing concentrations in wines made respectively from Grenache, Carignan, Cinsault, Merlot, Carbernet Sauvignon and Cabernet Franc grapes; the concentrations of peonidin and malvi…
Copy-number fluctuation by unequal crossing-over in the chicken avidin gene family.
2001
The chicken avidin gene (AVD) forms a closely clustered gene family together with several avidin-related genes (AVRs). In this study, we used fluorescence in situ hybridization on extended DNA fibers (fiber-FISH) to show that the number of the AVD and AVR genes differs between individuals. Furthermore, the gene copy-number showed wide somatic variation in white blood cells of the individuals. The molecular mechanism underlying the fluctuation is most probably unequal crossing-over and/or unequal sister chromatid exchange, as judged by the Gaussian distribution of the gene counts. By definition, an increase in gene number on one locus should be accompanied by a decrease on the other locus in…
Characterization and chromosomal localization of the chicken avidin gene family
2000
Chicken avidin is a biotin-binding protein expressed under inflammation in several chicken tissues and in the oviduct after progesterone induction. The gene encoding avidin belongs to a family that has been shown to include multiple genes homologous to each other. The screening and chromosomal localization studies performed to reveal the structure and organization of the complete avidin gene family is described. The avidin gene family is arranged in a single cluster within a 27-kb genomic region. The cluster is located on the sex chromosome Z on band q21. The organization of the genes was determined and two novel avidin-related genes, AVR6 and AVR7, were cloned and sequenced.
Synthesis and noncovalent protein conjugation of linear-hyperbranched PEG-poly(glycerol) alpha,omega(n)-telechelics.
2009
Linear-hyperbranched, heterobifunctional alpha,omega(n) telechelic block copolymers consisting of a linear poly(ethylene glycol) (PEG) chain and a hyperbranched polyglycerol (PG) block have been prepared in five steps, using a protected amino-functional initiator. The polyfunctionality omega(n) (OH groups) can be adjusted by the degree of polymerization (DP(n)) of the polyglycerol block. Subsequent introduction of a single biotin unit by amidation in alpha-position permitted noncovalent bioconjugation with avidin.

Site-specific halloysite functionalization by polydopamine: A new synthetic route for potential near infrared-activated delivery system
2022
Abstract Halloysite nanotubes (HNTs) represent a versatile core structure for the design of functional nanosystems of biomedical interest. However, the development of selective methodologies for the site-controlled functionalization of the nanotubes at specific sites is not an easy task. This study aims to accomplish a procedure for the site-selective/specific, “pin-point”, functionalization of HNTs with polydopamine (HNTs@PDA). This goal was achieved, at pH 6.5, by exploiting the basicity of ZnO nanoparticles anchored on the HNTs external surface (HNTs@ZnO) to induce a punctual polydopamine polymerization and coating. The morphology and the chemical composition of the nanomaterial was demo…
Ecos ovidianos en una adaptación de Eurípides: Hécuba triste de Pérez de Oliva
2014
Hécuba triste de Pérez de Oliva, considerada una de las primeras traducciones a lengua vernácula de una tragedia griega, es una adaptación peculiar de la Hécuba de Eurípides que incorpora notables cambios, algunos de ellos por influencia de otras tragedias griegas. En este trabajo estudiamos varios motivos utilizados por Oliva que remiten a otros textos, entre los que destacan obras relacionadas directa o indirectamente con Ovidio.
Aktuālās vēja elektrostaciju tiesiskā regulējuma problēmas Latvijā
2022
Strauji tuvojas brīdis, kad vides stāvokļa pasliktināšanos un klimata pārmaiņas apturēt vairs nebūs iespējams, tāpēc ir vajadzīgi risinājumi, kas ļautu apmierināt šodienas dzīves vajadzības, tai skaitā pieprasījumu pēc enerģijas, vienlaicīgi neapdraudot nākamo paaudžu iespējas dzīvot labvēlīgā vidē. Ar vēja elektrostaciju palīdzību ir iespējams saražot nepieciešamo elektroenerģiju, turklāt neradot videi kaitīgas emisijas. Neskatoties uz vēja sniegtajām priekšrocībām, Latvija vēja enerģijas ieguves attīstībā uz citu Eiropas valstu fona šobrīd ievērojami iepaliek. Šī darba ietvaros tiks aplūkots vēja elektrostacijām piemērojamais tiesiskais regulējums Latvijā, identificēti trūkumi tajā un mek…
Improved antifouling properties and selective biofunctionalization of stainless steel by employing heterobifunctional silane-polyethylene glycol over…
2016
AbstractA straightforward solution-based method to modify the biofunctionality of stainless steel (SS) using heterobifunctional silane-polyethylene glycol (silane-PEG) overlayers is reported. Reduced nonspecific biofouling of both proteins and bacteria onto SS and further selective biofunctionalization of the modified surface were achieved. According to photoelectron spectroscopy analyses, the silane-PEGs formed less than 10 Å thick overlayers with close to 90% surface coverage and reproducible chemical compositions. Consequently, the surfaces also became more hydrophilic, and the observed non-specific biofouling of proteins was reduced by approximately 70%. In addition, the attachment of E…
