Evidence for Positive Selection in the Capsid Protein-Coding Region of the Foot-and-Mouth Disease Virus (FMDV) Subjected to Experimental Passage Regi…
2001
We present sequence data from two genomic regions of foot-and-mouth disease virus (FMDV) subjected to several experimental passage regimens. Maximum-likelihood estimates of the nonsynonymous-to-synonymous rate ratio parameter (dN/dS) suggested the action of positive selection on some antigenic sites of the FMDV capsid during some experimental passages. These antigenic sites showed an accumulation of convergent amino acid replacements during massive serial cytolytic passages and also in persistent infections of FMDV in cell culture. This accumulation was most significant at the antigenic site A (the G-H loop of capsid VP1), which includes an Arg-Gly-Asp (RGD) cellular recognition motif. Our …
Selective encapsulation and enhancement of the emission properties of a luminescent Cu(I) complex in mesoporous silica
2018
We describe a synthetic approach to prepare new luminescent silica‐based materials through the encapsulation of a neutral copper(I) complex inside the pores of mesoporous silica nanoparticles (MSN). The copper(I) complex is present, in the solid state, as two polymorphs, blue and yellow emissive, and in solution it shows a pale yellow color that is also mirrored by an emission in the yellow‐orange region of the electromagnetic spectrum. The X‐ray structures of single crystals have been obtained for both polymorphs. The complex encapsulation in MSN is achieved by its entrapment inside micelles followed by condensation of the silica source. Interestingly, the entrapment leads to the isolation…
Immobilization of proteins in silica gel: Biochemical and biophysical properties
2015
The development of silica-based sol-gel techniques compatible with the retention of protein structure and function started more than 20 years ago, mainly for the design of biotechnological devices or biomedical applications. Silica gels are optically transparent, exhibit good mechanical stability, are manufactured with different geometries, and are easily separated from the reaction media. Biomolecules encapsulated in silica gel normally retain their structural and functional properties, are stabilized with respect to chemical and physical insults, and can sometimes exhibit enhanced activity in comparison to the soluble form. This review briefly describes the chemistry of protein encapsulat…

Gingivīta novērtēšana, izmantojot attālinātu fotopletismogrāfiju
2020
Pētījuma mērķis ir novērtēt smaganu perfūziju izmeklējamām personām izmantojot photopletizmogrāfijas metodi. Viens no pētījuma mērķiem bija reģistrēt kapsacīna izraisīto neiro-iekaisuma efektu. Metodoloģija Šķērsgriezuma pētījums, tika veikts iekļaujot nelielu izmeklējamo personu grupu , izmeklējamās personas pirms pētījuma veikšanas tika iepazīstinātas ar protokolu un rakstiski apstiprināja dalību pētījumā. Pētījuma gaitā smaganu perfūzijas tika reģistrēta miera apstākļos, un aplicējot uz smaganu virsmas kapsacīnu saturošu piparu ekstraktu, kas izraisīja pārejošu neirogēnu iekaisumu, ar tam raksturīgo hiperēmiju. Signāla reģistrācija tika veikta novietojot uz galvas izmeklējamai personai f…

Faire face ou faire avec. Situations de vulnérabilité et situations de handicap
2020
Nous sommes tous victime lorsqu’un aléa survient au cours d’un déplacement (grève, panne, situation climatique exceptionnelle, etc.), par définition imprévisible. Mais il peut rendre vulnérables les personnes en situation de handicap cognitif et/ou mental plus particulièrement. La distinction sémantique entre situation de handicap et situation de vulnérabilité doit ici garder tout son sens. Et la tendance à employer indifféremment l’une et l’autre notion en sciences humaines et sociales, mérite d’être dénoncée. Différencier l’une et l’autre notion, c’est admettre et reconnaître les tactiques résilientes que les personnes en situation de handicap mettent en œuvre quotidiennement pour compens…
Evidence of conservative treatment for overuse injuries analysis of systematic reviews
2011
Overuse injuries are common among top athletes and people who exercise regularly. Conservative, non-pharmacological methods are used widely to treat overuse injuries and there is a large body of literature, including multiple systematic reviews, evaluating different terms of treatment. This literature needs summarizing and critiquing. Objective of this study was to evaluate the effectiveness of different methods of conservative treatment on overuse injuries and to provide an analysis of systematic reviews. Published systematic reviews were identified by searching Medline, PEDro, Cochrane and Sportdiscus databases from the year 1996 to July 2010. Reference lists of identified studies were al…
The Hexameric Resorcinarene Capsule as a Brønsted Acid Catalyst for the Synthesis of Bis(heteroaryl)methanes in a Nanoconfined Space
2019
Herein, we show that the hexameric resorcinarene capsule C is able to catalyze the formation of bis(heteroaryl)methanes by reaction between pyrroles or indoles and carbonyl compounds (α-ketoesters or aldehydes) in excellent yields and selectivity. Our results suggest that the capsule can play a double catalytic role as a H-bond catalyst, for the initial activation of the carbonyl substrate, and as a Bronsted acid catalyst, for the dehydration of the intermediate alcohol.
