Los «grupos financiero-industriales» en la Federación Rusa : Nuevas tendencias en el establecimiento de vínculos entre las esferas financiera y produ…
2000
El presente artículo tiene como objetivo estudiar las relaciones existentes entre las esferas financiera y productiva de la economía rusa. Para ello se analiza, en primer lugar, los aspectos legislativos de la formación de los grupos financiero-industriales, describiéndose los requisitos y las restricciones básicas para la formación de estos grupos. En segundo lugar, se revisa la distinta evolución desarrollada por los grupos financieroindustriales cuantificando el fenómeno, por un lado, así como su ubicación en el espacio ruso, por otro. En tercer lugar, se elabora una caracterización de los grupos financieros, enumerando los principales criterios de integración que se han detectado para l…
Data from: Microbiome symbionts and diet diversity incur costs on the immune system of insect larvae
2017
Communities of symbiotic microorganisms that colonize the gastrointestinal tract play an important role in food digestion and protection against opportunistic microbes. Diet diversity increases the number of symbionts in the intestines, a benefit that is considered to impose no cost for the host organism. However, less is known about the possible immunological investments that hosts have to make in order to control the infections caused by symbiont populations that increase due to diet diversity. By using taxonomical composition analysis of the 16S rRNA V3 region, we show that Enterococci are the dominating group of bacteria in the midgut of the larvae of the greater wax moth (Galleria mell…
Evidence that water transmits Vibrio vulnificus biotype 2 infections to eels
1995
Vibrio vulnificus biotype 2 is classically considered an obligate eel pathogen. However, it has recently been associated with one human septicemic case. In this paper, the opportunistic behavior of this pathogen is discussed. The bacterium can survive alone in brackish water or attached to eel surfaces for at least 14 days. It is able to spread through water and infect healthy eels by using skin as a portal of entry. These results suggest that water and infected eels may act as reservoirs of infection. A capsule seems to be essential for waterborne infectivity, which would explain why cells recovered from naturally diseased eels give rise to pure cultures of opaque colonies. The spread of t…
A plasma protein corona enhances the biocompatibility of Au@Fe3O4 Janus particles
2015
AbstractAu@Fe3O4 Janus particles (JPs) are heteroparticles with discrete domains defined by different materials. Their tunable composition and morphology confer multimodal and versatile capabilities for use as contrast agents and drug carriers in future medicine. Au@Fe3O4 JPs have colloidal properties and surface characteristics leading to interactions with proteins in biological fluids. The resulting protein adsorption layer (“protein corona”) critically affects their interaction with living matter. Although Au@Fe3O4 JPs displayed good biocompatibility in a standardized in vitro situation, an in-depth characterization of the protein corona is of prime importance to unravel underlying mecha…
Targeting the vascular endothelial growth factor system to prevent ovarian hyperstimulation syndrome
2008
BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) typically occurs when ovaries are primed with FSH/ LH and subsequently exposed to hCG. The ultimate pathophysiological step underlying this clinical picture is increased vascular permeability (VP). METHODS: A search of the literature was carried out using PubMed and the authors’ files. RESULTS: In rodents and humans, the expression of vascular endothelial growth factor (VEGF) and VEGF receptor 2 (VEGFR-2) mRNA increases during ovarian stimulation. With the administration of hCG, the expression of each rises to a maximum. Expression of VEGF/VEGFR-2 mRNAs correlates with enhanced VP, with both peaking 48 h following an injection of hCG. Imm…
'TRPing' synaptic ribbon function in the rat pineal gland: neuroendocrine regulation involves the capsaicin receptor TRPV1.
2009
Synaptic ribbons (SRs) are presynaptic structures thought to regulate and facilitate multivesicular release. In the pineal gland, they display a circadian rhythm with higher levels at night paralleling melatonin synthesis. To gain more insight into the processes involved and the possible functions of these structures, a series of experiments were conducted in rodents. We studied the regional distribution of a molecular marker of pineal SRs, the kinesin motor KIF3A in the gland. Respective immunoreactivity was abundant in central regions of the gland where sympathetic fibers were less dense, and vice versa, revealing that intercellular communication between adjacent pinealocytes is enhanced …
Tiroiditis de Hashimoto: Microcirculación Lingual y Labial en Pacientes Afectados por Macroglosia
2007
The aim of this study is to estudy lingual and labial microcirculation differences among healthy subjects and those with Hashimoto's thyroiditis affected by macroglossia. Twenty healthy patients and 20 patients suffering from Hashimoto's thyroiditis were examined. Labial and lingual capiUaroscopy were used to investigate the characteristics of microcirculation. For each patient we evaluated visibility, course, tortuosity and the possible presence of microhaemorrhages, average calibre of capillary loops and the number of visible capillary loops per square millimetre. The investigations of the labial and lingual mucous were simple, non invasive and repeatable for each patient. In Hashimoto's …
Assessment of available potential of agro - biomass and energy crops phytomass for biofuel production in Ukraine
2017
Przedstawiono analizę publikacji wyświetlających problem wykorzystania biomasy jako odnawialnego źródła energii na Ukrainie. Wykorzystanie biomasy w systemie paliwowo -energetycznym kraju jest bardzo ważnym zadaniem. Celem badań była ocena dostępnego potencjału biomasy rolnej oraz fitomasy z upraw energetycznych do produkcji biopaliwa. Przedstawiono technikę oceny, określono potencjał i obliczono efektywność energetyczną wykorzystania biomasy na Ukrainie. Udowodniono, że wykorzystanie biomasy rolniczej do celów energetycznych w Ukrainie pozwala zmniejszyć zależność energetyczną kraju od nieodnawialnych źródeł energii.
Analysis of Renovation Works in Cappuccinelli Social Housing District in Trapani
2022
The refurbishment of public residential districts represents a current and complex problem. The Cappuccinelli Social Housing (SH) district in Trapani, designed in the late 1950s by Michele Valori and built during the 1960s, is emblematic of the architectural quality and technological innovation of the time it was designed, but at the same time represents the physical and social decay that occurred just after its construction. The neighborhood was examined through a combination of inspections and documentary research. The inspections were conducted for the entire district in order to identify the recurrent external degradation of building components and the related causes, both physical and …
A magnetostrictive generator for sensors network
2017
In this paper we present a vibration harvesting electric power generator based on magnetostrictive effect for sensors network in hazardous area and we validate it experimentally. The generator has been designed by using Dynamic Preisach hysteresis Model (DPM). DPM is a development of classical Preisach Model which is able to include dynamical features in the mathematical model of hysteresis. We measure the output power capability of the generator and we estimate its power density generation capability.
