Exosome A Clinical Compendium - Chapter 1: Exosome basic mechanisms
2019
Cell-cell communication plays a key role in maintaining homeostasis in multicellular organism. Cells communicate each other not only via the canonical pathways (cytokines, neurotransmitters, direct contact, ECM-mediated interactions or hormones) but also releasing extracellular vesicles that can reach different regions of the organism acting as a new “endocrine signalling mechanism”. Among extracellular vesicles, exosomes are emerging as efficient players to modulate target cells phenotype through the delivery to compliant receiving cells of a multitude of molecules such as mRNAs, microRNAs, long non-coding RNAs, DNA, lipids, metabolites and proteins. A deeper understanding of their content…

2016
Ievads: Ar veselības aprūpi saistītu infekciju izplatība turpina pieaugt visā pasaulē un tiek lēsts, ka tās būs 5-10% stacionārā iegūtās un ar augstāko līmeni ķirurģijas un intensīvās terapijas nodaļās. Tika veikts pētījums ar nozokomiālām infekcijām divās slimnīcās Latvijā. Šajā pētījumā bija 17.5% nozokomiālo infekciju gadījumu (226 pacientiem no 1291). Mērķis: Pētījuma mērķis ir analizēt gram-negatīvo strutainu infekciju sastopamību Traumatoloģijas un Ortopēdijas slimnīcā. Materiāli un metodes: Retrospektīvs pētījums ietver paraugus no pacientiem, kuri ieradās uz plānotu operāciju TOS laika posmā no 02.12.2014. līdz 28.08.205. Mikroorganismi tika izolēti no operācijas vietas, brūces, āda…
Dynamical amplification of electric polarization through nonlinear phononics in 2D SnTe
2020
Ultrafast optical control of ferroelectricity using intense terahertz fields has attracted significant interest. Here we show that the nonlinear interactions between two optical phonons in SnTe, a two-dimensional in-plane ferroelectric material, enables a dynamical amplification of the electric polarization within subpicoseconds time domain. Our first-principles time-dependent simulations show that the infrared-active out-of-plane phonon mode, pumped to nonlinear regimes, spontaneously generates in-plane motions, leading to rectified oscillations in the in-plane electric polarization. We suggest that this dynamical control of ferroelectric material, by nonlinear phonon excitation, can be ut…

Adaptación visual a la distorsión luminosa y agudeza de bajo contraste en pacientes bajo terapia corneal refractiva.
2015
Antecedentes: La Ortoqueratología (OK) o terapia refractiva corneal (CRT) es un tratamiento para corregir el error refractivo mediante el moldeo la cara anterior de la córnea con la aplicación programada de unas lentes de contacto rígidas permeables al gas (RGP) diseñadas especialmente (LC). La técnica es efectiva y la FDA la aprobó para un error refractivo de -6,00D de esfera y -1,50D de cilindro. Algunos profesionales afirman que se pueden conseguir correcciones para valores superiores de miopía y astigmatismo, hipermetropía y presbicia, pero estas aplicaciones están en este trabajo fuera de contexto. A pesar de su eficacia, la técnica tiene algunas desventajas intrínsecas a la remodelaci…
Electrochemical Oxidation of Carboxylic Acids in Water at Boron-Doped Diamond (BDD) Anodes in the Range of Potential of Oxygen Evolution: Detection M…
2013
The electrochemical oxidation in water solutions of selected carboxylic acids (namely oxalic, formic, acetic, maleic, and succinic) at boron-doped diamond (BDD) anodes was investigated by polarization and chronoamperometric measurements. In the presence of low concentrations of carboxylic acids, current densities changed approximately linearly with the acid concentrations. Furthermore, when the current densities were plotted as a function of the chemical oxygen demand, a similar response was observed for all the investigated acids with the exception of oxalic acid. For high carboxylic acid concentrations, the linear variation is often loosen and different behaviors are observed depending on…

Howard–Dolman stereovision test at different opponent colour stimuli
2011
The purpose of this study was to investigate visual depth perception of real physical colour stimuli with red-green and blue-yellow opponency. We modified the Howard–Dolman stereotest where subjects should determine the closer of two bars emitting the light of definite colour placed in front of a CRT monitor served as colour background. Two-alternative forced-choice paradigms were used to determine depth perception threshold values. Thresholds close to 5–10 arcsec for luminance and colour contrast stimuli were revealed both for red-green and blue-yellow stimuli. A term, stereosensitivity – a reciprocal magnitude of the stereothreshold – was introduced to separately analyse luminance and col…
