A highly sensitive dispersive micro-solid phase extraction (D-μ-SPE) method combining an ionic liquid (IL) and multi-walled carbon nanotubes (MWCNTs) for inorganic As species (As(III) and As(V)) species separation and d...

Melanoma Antigens Genes (MAGE) constitutes a mutagenic family divided in two subfamilies, MAGE-I and MAGE-II, according to its tissue pattern expression. While MAGE-I in adult humans are only expressed in testis and tumo...

A green and sustainable approach to the direct synthesis ofthioesters has been developed using Fe3O4 as a low-cost, easilyprepared, reusable and environmentally safe catalyst. The crossdehydrogenative coupling (CDC) of v...

Blends and composites were obtained by mixing commercial metallocenic linear low density polyethylene (LLDPE) and isotactic polypropylene, with different molecular weight polydimethylsiloxanes (PDMS), including a vinyl e...

A method to monitor seed germination that combines isothermal calorimetry and imbibition measurements is reported. Individual seeds of three cultivars of soybean seeds (A7636RG, Munasqa and DM5.8RR) and one of radish...

Cadmium (Cd) is a toxic heavy metal found in tobacco, water, and food. Exposure to this metal can be harmful to health, causing kidney, bone, and respiratory problems, and even cancer. Furthermore, Cd exposure through ma...

Flaveria bidentis is an invasive plant containing Sulfated Flavonoids (SFs) with therapeutic potential. The extraction of these compounds would add value to the biomass generated during weeding. This work reports the opt...

The photochemical one-electron oxidation of alkyl aryl selenides was studied by means of laser flash photolysis (355 nm). Quenching of the sensitizers in their excited state leads to selenide radical cation in the presen...

The co-production of bio-char and upgraded bio-oil by fast pyrolysis of raw and sulfuric-acid pretreated agro-industrial wastes (corn cob, sugarcane bagasse and sunfower seed hull) was investigated to valorize wastes as ...

This study comparatively examined spectroscopic features, photosynthetic parameters and energy partitioning in plants of Fittonia albivenis cv. Agyroneura and Fittonia albivenis cv. Verschaffeltii with different pigmenta...

An on-line inorganic (InHg) and organomercury (OrHg) species separation, preconcentration and determination system consisting of cold vapor atomic absorption spectrometry (CV-AAS) coupled to a flow injection (FI) method ...

A new method for pre-concentration/separation and determination of 2,4-dichlorophenoxyacetic acid (2,4-D) by solid-surface fluorescence (SSF) is proposed. The herbicide was complexed with Rhodamine B at pH 7.0 in the pre...

Density Functional Theories (DFT) methods were applied to describe the catalytic effect of a series of sulfonated NHC gold(I) complexes In order to explain the experimental results obtained in the hydration of phenylacet...

Effects induced by the incorporation of lipid II (LII) molecule into phosphatidylglycerol (PG) membranes were studied by Raman microspectroscopy. Spectral behavior of multilayer vesicles in liquid crystalline and gel pha...

Cyclin-dependent kinase A (CDKA) is a key component for cell cycle progression. The catalytic kinase activity depends on the protein's ability to form an active complex with cyclins and on phosphoregulatory mechanisms. C...

We have shown that mice infected with mouse hepatitis virus A59 develop autoantibodies (autoAb) to liver and kidney fumarylacetoacetate hydrolase (FAH). Because it has been proposed that the immune system is stimulated b...

Polygonum L. genus (Polygonaceae) is represented in Argentina by 21 species and some of them have been used in the traditional medicine of our country to treat affections related with fungal infections, such as skin ailm...

La utilización de la técnica de PDB en el campo farmacéutico se ilustra mediante algunos ejemplos que comprenden la determinación de constantes de equilibrio ácido-base de nuevas moléculas de interés farmacéutico...

En los últimos años existe una búsqueda y revalorización de sustratos provenientes de fuentes naturales que presenten constituyentes y/o productos derivados aplicables al desarrollo de alimentos, los cuales incidan e...

Estudiar las interfaces sólido/líquido que involucran partículas coloidales dispersas en concentraciones moderadas, las cuales proveen una alta concentración de sitios superficiales de reacción. La sílice coloidal ...

Desde principios del siglo XIX, la comunidad científica ha reconocido al hidrógeno como una potencial fuente de energía. Hasta ahora, la producción de hidrógeno se ha dirigido en su mayor parte hacia la industria pe...

Para este trabajo se han seleccionado como moléculas prueba o representativas de COVs al etanol, acetaldehído y ácido acético. Esta elección esta basada en la amplia gama de procesos “caseros” e industriales que...

El objetivo principal de este trabajo es la determinación de características espectroscópicas en fase gaseosa y en solución de compuestos orgánicos liberados a la atmósfera y el estudio de sus reacciones heterogén...
