Cellular responses and HSP70 expression during wound healing in Holothuria tubulosa (Gmelin, 1788).

2014

Wound repair is a key event in the regeneration mechanisms of echinoderms. We studied, at the behavioural, cellular and molecular levels, the wound healing processes in Holothuria tubulosa after injuries to the body wall. The experiments were performed for periods of up to 72 h, and various coelomocyte counts, as well as the expression of heat shock proteins (HS27, HSP70 and HSP90), were recorded. Dermal wound healing was nearly complete within 72 h. In the early stages, we observed the injured animals twisting their bodies to keep their injuries on the surface of the water for the extrusion of the buccal pedicles. At the cellular level, we found time-dependent variations in the circulating…

Święcenia prezbiteratu w Kościołach syryjskich. Historia i struktura obrzędu

2018

Sakrament święceń należy do depozytu najistotniejszych misteriów pozostawionych Kościołowi przez Jezusa Chrystusa. Przekazywana w nim sukcesja apostolska jest gwarantem ciągłości tradycji i prawdziwości chrześcijańskiego kultu, skoncentrowanego na wciąż przychodzącym, dzięki posłudze ołtarza, Panu. Chociaż wynikające ze święceń funkcje są wspólne całemu Kościołowi, to jednak różne tradycje liturgiczne wypracowały własne rozumienie tegoż sakramentu i związanej z nim posługi. Niniejszy artykuł stanowi refleksję nad istotą kapłaństwa w stopniu prezbitera w przestrzeni liturgicznej Kościołów syryjskich. Autor wychodzi od prezentacji rozumienia sakramentu oraz jego trwałości i obowiązywalności, …

Liturgia domowa sprawowana przez małżonków w codzienności

2020

Określenie chrześcijańskiej rodziny mianem „sanktuarium domowego Kościoła” pokazuje, że jest ona miejscem przygotowywania się jej członków do udziału w liturgii sprawowanej we wspólnocie parafialnej. Jednocześnie jest też miejscem przedłużania w domu kultu sprawowanego w kościele parafialnym. Jedną z głównych potrzeb rodziny i małżeństwa jest religijna kultura rodzinna, wyrażana w domowym zaciszu na wspólnej modlitwie. Jej pielęgnowanie ma prowadzić do stworzenia swoistego rytuału religijnego danej rodziny. Aby taki rytuał był także akceptowany i praktykowany przez młode pokolenie, musi być czymś autentycznie przeżywanym przez małżonków. Formacja, którą dzieci otrzymują od rodziców, ma im p…

Green tea extract assisted low-temperature pasteurization to inactivate enteric viruses in juices.

2020

The current popularity of minimally processed foods is an opportunity for natural antimicrobial agents to be combined with mild heat treatments to act synergistically in reducing viral foodborne pathogens. Viral inactivation by heat-treatments (at 25, 40, 50 and 63 °C for 30 min) combined with aged green tea extract (aged-GTE) was initially evaluated in phosphate buffered saline (PBS) against murine norovirus (MNV-1) and hepatitis A virus (HAV) by cell culture, and against human norovirus by in situ capture RT-qPCR. The combination of aged-GTE and heat treatment at 50 °C for 30 min exerted strong antiviral activity, reducing by more than 5 log MNV-1 infectivity in PBS. Heating at 40 °C for …

Green sulphur bacteria as a component of the photosynthetic plankton community in small dimictic humic lakes with an anoxic hypolimnion

2013

High bacteriochlorophyll (BChl) concentrations in the anoxic water layers of some humic lakes have indicated that green sulphur bacteria (GSB) may be ecologically significant. The abundance and spatial distribution of GSB were therefore addressed in 13 small humic lakes using fragment analysis and sequencing of PCR-amplified 16S rRNA genes. GSB were detected from lakes where the photosynthetically active radiation was at least 1.1 µE m-2 s-1 at the oxic-anoxic boundary layer. In these lakes, 13 to 42% of the 16S rRNA gene sequences of the anoxic water column were assigned to GSB. The spatial distribution of GSB was tightly correlated with the spectrophotometrically measured BChl concentrati…

Added Value and Clinical Significance of Nonlinear Variability Indices of Walking Stride Interval in Neurodegenerative Diseases

2020

AbstractThough self-paced walking is highly stereotyped, the stride interval fluctuates from one stride to the next around an average value with a measurable statistical variability. In clinical gait analysis, this variability is usually assessed with indices such the standard deviation or the coefficient of variation (CV). The aim of this study is to understand the added value that nonlinear indices of walking stride interval variability, such as Hurst exponent (H) and Minkowski fractal dimension (D), can provide in a clinical context and to suggest a clinical significance of these indices in the most common neurodegenerative diseases: Parkinson, Huntington, and amyotrophic lateral scleros…

Nonlinear Dynamics Techniques for the Detection of the Brain Areas Using MER Signals

2008

A methodology for identifying brain areas from the brain MER signals (microelectrode recordings) is presented, which is based on a nonlinear feature set. We propose nonlinear dynamics measures such as correlation dimension, Hurst exponent and the largest Lyapunov exponent to characterize the dynamic structure. The MER records belong to the Polytechnical University of Valencia, 24 records for each zone (black substance, thalamus, subthalamus nucleus and uncertain area). The detection of each area using characteristics derived from complexity analysis was obtained through a classifier (support vector machine). The joint information between areas is remarkable and the best accuracy result was …

FRACTALITY EVIDENCE AND LONG-RANGE DEPENDENCE ON CAPITAL MARKETS: A HURST EXPONENT EVALUATION

2014

Since the existence of market memory could implicate the rejection of the efficient market hypothesis, the aim of this paper is to find any evidence that selected emergent capital markets (eight European and BRIC markets, namely Hungary, Romania, Estonia, Czech Republic, Brazil, Russia, India and China) evince long-range dependence or the random walk hypothesis. In this paper, the Hurst exponent as calculated by R/S fractal analysis and Detrended Fluctuation Analysis is our measure of long-range dependence in the series. The results reinforce our previous findings and suggest that if stock returns present long-range dependence, the random walk hypothesis is not valid anymore and neither is…

Multi-agent-based Order Book Model of financial markets

2006

We introduce a simple model for simulating financial markets, based on an order book, in which several agents trade one asset at a virtual exchange continuously. For a stationary market the structure of the model, the order flow rates of the different kinds of order types and the used price time priority matching algorithm produce only a diffusive price behavior. We show that a market trend, i.e. an asymmetric order flow of any type, leads to a non-trivial Hurst exponent for the price development, but not to "fat-tailed" return distributions. When one additionally couples the order entry depth to the prevailing trend, also the stylized empirical fact of "fat tails" can be reproduced by our …
