Role of quercetin on sterigmatocystin-induced oxidative stress-mediated toxicity.

2021

Oxidative stress appears to be a common trigger for many of the effects associated with the exposure to various mycotoxins, including sterigmatocystin (STE). However, studies to alleviate STE toxicity through the use of natural antioxidants are sparsely reported in literature. In the present study, the cytoprotective effect of quercetin (QUE) was tested in SH-SY5Y cells against STE-induced oxidative stress and cytotoxicity. The MTT assay revealed that STE decreased cell viability, whereas pre-treatment of cells with QUE restored it. The QUE was also found to counteract STE-induced ROS generation and decrease STE-induced up-regulation of the expression of the stress-inducible enzymes HO-1 an…

Euler Characteristics of Moduli Spaces of Curves

2005

Let ${mathcal M}_g^n$ be the moduli space of n-pointed Riemann surfaces of genus g. Denote by ${\bar {\mathcal M}}_g^n$ the Deligne-Mumford compactification of ${mathcal M}_g^n$. In the present paper, we calculate the orbifold and the ordinary Euler characteristic of ${\bar {\mathcal M}}_g^n$ for any g and n such that n>2-2g.

FLUMO: FLexible Underwater MOdem

2019

The last years have seen a growing interest in underwater acoustic communications because of its applications in marine research, oceanography, marine commercial operations, the offshore oil industry and defense. High-speed communication in the underwater acoustic channel has been challenging because of limited bandwidth, extended multipath, refractive properties of the medium, severe fading, rapid time variation and large Doppler shifts. In this paper, we show an implementation of a flexible Software-Defined Acoustic (SDA) underwater modem, where modulation parameters are completely tunable to optimize performance. In particular, we develop the system architecture following two key ideas. …

Brothers, sisters and the rearrangements of property on the Sicilian island of Stromboli in the nineteenth century

2010

This article focuses on property relationships among siblings, especially on sales and exchanges of land, houses and other items, on the small Sicilian island of Stromboli in the Aeolian archipelago during the nineteenth century. Stromboli's economy incorporated farming and seafaring activities. The ‘modular structure’ of houses and wealth was characterised by partible inheritance, with equal inheritance shares or endowments for both sons and daughters, which was permitted under the Civil Code of the Kingdom of the Two Sicilies. Siblings therefore had the possibility of exchanging, assembling and disposing of shares through sales. For this reason sibling relations had a strong impact on the…

Reeducación de la marcha: fase de oscilación

2022

Este vídeo forma parte de una serie de vídeos que muestran la ejecución de diversas maniobras de fisioterapia siguiendo las bases del Concepto Bobath. En él se muestra la facilitación del despegue del talón y de la fase de oscilación de la marcha en el miembro inferior parético, en una mujer con hemiparesia izquierda tras ictus hemorrágico. Cabe destacar que las características funcionales de la modelo pueden no estar alineadas con los objetivos de la maniobra mostrada. Estos se detallan al inicio del vídeo. La idoneidad de la maniobra para una determinada persona dependerá de que esta necesite conseguir dichos objetivos terapéuticos.

Impact of the flame retardant 2,2'4,4'-tetrabromodiphenyl ether (PBDE-47) in THP-1 macrophage-like cell function via small extracellular vesicles

2023

2,2’4,4’-tetrabromodiphenyl ether (PBDE-47) is one of the most widespread environmental brominated flame-retardant congeners which has also been detected in animal and human tissues. Several studies have reported the effects of PBDEs on different health issues, including neurobehavioral and developmental disorders, reproductive health, and alterations of thyroid function. Much less is known about its immunotoxicity. The aim of our study was to investigate the effects that treatment of THP-1 macrophage-like cells with PBDE-47 could have on the content of small extracellular vesicles’ (sEVs) microRNA (miRNA) cargo and their downstream effects on bystander macrophages. To achieve this, we puri…

Tyramine Actions on

2017

The biogenic amines octopamine (OA) and tyramine (TA) modulate insect motor behavior in an antagonistic manner. OA generally enhances locomotor behaviors such as Drosophila larval crawling and flight, whereas TA decreases locomotor activity. However, the mechanisms and cellular targets of TA modulation of locomotor activity are incompletely understood. This study combines immunocytochemistry, genetics and flight behavioral assays in the Drosophila model system to test the role of a candidate enzyme for TA catabolism, named Nazgul (Naz), in flight motor behavioral control. We hypothesize that the dehydrogenase/reductase Naz represents a critical step in TA catabolism. Immunocytochemistry rev…
