Analysis of the Cellular Roles of MOCS3 Identifies a MOCS3-Independent Localization of NFS1 at the Tips of the Centrosome
2019
The deficiency of the molybdenum cofactor (Moco) is an autosomal recessive disease, which leads to the loss of activity of all molybdoenzymes in humans with sulfite oxidase being the essential protein. Moco deficiency generally results in death in early childhood. Moco is a sulfur-containing cofactor synthesized in the cytosol with the sulfur being provided by a sulfur relay system composed of the L-cysteine desulfurase NFS1, MOCS3, and MOCS2A. Human MOCS3 is a dual-function protein that was shown to play an important role in Moco biosynthesis and in the mcm(5)s(2) U thio modifications of nucleosides in cytosolic tRNAs for Lys, Gln, and Glu. In this study, we constructed a homozygous MOCS3 …

Assessment of Effectiveness of Organo-Mineral Fertilizer Made of Coffee Spent Grounds and Biomass Ash
2019
Optimization of the biodegradable wastes management is one of the main goals of the activities taken up in the European Union. The aim of the present paper is to define the possibilities of supporting the process of golden rod yield (Solidago canadensis L.) by using different mineral-organic fertilizers, in a form of granulated substances, produced from extracted coffee wastes (CSG) as well as from ash which is the result of woody biomass combustion. Golden rod, as a potential energetic plant, is very easy to grow because it covers the grounds which are not utilized agriculturally or the ones localised in the close neighbourhood of industrial areas. For certain experimental purposes, a fiel…
THE POSSIBILITY OF DISPOSING OF SPENT COFFEE GROUND WITH ENERGY RECYCLING
2015
The current policy of waste management requires, above all, a gradual reduction of waste amount and, to a larger extent, forces us to seek new methods of waste disposal. Recycling the energy contained in biomass waste is a more and more universally applied method of thermal converting. Biomass combustion allows saving fossil fuels which fits into sustainable development. This paper checks the possibility of using spent coffee ground (SCG) in energy recycling using a combustion process. This particular biomass type up to now has not been widely examined, which inclines to consider its usage as a potential additive to alternative fuels. In the study, we examined the quality of fuel, which was…
Dynamic of Components Leachate from Experimental Fertilizers in Leaching Test
2018
Organic matter contained in the waste of food industry or occurring in the households, in the absence of contamination with other kind of waste, may be used to create a “fertiliser”, which could be even reused in the organic production of arable crops. Particular attention is drawn to the fertilisers which may be applied in the case of amateur cultivation of pot plants and in the allotment gardens. The paper presents the results of research regarding the dynamics of the release of nutrients from tablets created with the help of encapsulation of the mixture manufactured from solvent extraction waste of coffee (SCG), modified by the ash obtained from low temperature burning of biomass. In thi…
Impacto de la implementación de un modelo ecoformativo a través de proyectos estratégicos : el caso de la Universidad Castro Carazo (Costa Rica)
2020
La Universidad Castro Carazo ha adoptado un modelo educativo de ecoformación desde el año 2016. Para esto, ha sido necesaria la incorporación de buenas prácticas y estrategias de innovación pedagógica y curricular, como parte integral de sus procesos educativos y administrativos. En este artículo se detallan las prácticas y estrategias más relevantes: el diseño e implementación de un programa de especialización en docencia universitaria, la inauguración de un laboratorio de aprendizaje para el fomento del aprendizaje mediante la fabricación digital, los multientornos, y los mapas conceptuales, así como el fortalecimiento de un equipo de innovación curricular. Estos procesos disruptivos han …
The Synthesis, Characterization and Sintering of Nickel and Cobalt Ferrite Nanopowders
2012
The NiFe2O4 and CoFe2O4 ferrites were synthesized by two methods – chemical sol-gel self-combustion method and the high frequency plasma chemical synthesis and magnetic properties, crystallite size, specific surface area of synthesized products are characterized. Nanopowders synthesized in the high frequency plasma are with specific surface area in the range of (28 – 30) m2/g (the average particle size (38 – 40) nm, crystallite size ~40 nm). The ferrite nanopowders obtained by sol-gel self-combustion method have the specific surface area of (37 – 43) m2/g (average particle size (26 – 31) nm, crystallite size (10 – 20) nm). All synthesized nanopowders were sintered via pressure-less sinterin…
An antique lead coffin discovered in Évreux (Eure): a multidisciplinary study
2013
The Roman cemetery of le Clos au Duc in Évreux (Eure) lasted from the 1st to the 4th c. AD. The most common funerary practice in the 1st c. AD was cremation. From the beginning of the 2nd c. AD this rapidly gave place to inhumation burials. By the end of the 3rd c. lead coffins could be found in burials, but it remained a minority practice reserved for an elite. The 2010 excavation in Évreux allowed the recovery of an example of these. It was incomplete, but the good preservation of its remains made a multidisciplinary study possible. Apart from the bones of a young woman, the lead coffin contained coins, textile, fur, calcite (CaCO3) and insects. These results make it possible to retrace t…
Coffee Restores Expression of lncRNAs Involved in Steatosis and Fibrosis in a Mouse Model of NAFLD
2021
Background and aim: Coffee intake exerts protective effects against non-alcoholic fatty liver disease (NAFLD), although without fully cleared mechanisms. In this study we aimed to assess whether coffee consumption may influence the expression of long non-coding RNAs (lncRNAs) in the liver. Methods: C57BL/6J mice were fed a 12-week standard diet (SD), high-fat diet (HFD) or HFD plus decaffeinated coffee solution (HFD + coffee). Expression of specific lncRNAs involved in NAFLD was analyzed by real-time PCR. For the most differentially expressed lncRNAs, the analysis was also extended to their mRNA targets. Results: Decaffeinated coffee intake reduced body weight gain, prevented NAFLD, lowered…
Influences of social stress in the rewarding effects of mdma and alcohol
2015
La adicción a las drogas es un importante problema en nuestra sociedad con graves consecuencias jurídicas, médicas y sociales para los consumidores. Se trata de un trastorno caracterizado por la pérdida de control sobre el uso de la droga, su búsqueda compulsiva y la aparición de un estado emocional negativo en ausencia de la misma. El alcohol es la droga legal más consumida tanto por adultos como por adolescentes. Por otra parte, entre las sustancias ilegales, los datos epidemiológicos apuntan que el éxtasis o MDMA es una sustancia ampliamente consumida entre los adolescentes y adultos jóvenes sobre todo en fiestas “rave” donde los consumidores pasan horas, incluso días, haciendo uso de es…
