Assessment of neutralizing capacity of antibodies raised in mice against a Crotalus durissus terrificus phosphodiesterase
(Sociedad Argentina de Investigación ClínicaSociedad de Farmacología ExperimentalSociedad Argentina de BiologíaSociedad Argentina de ProtozoologíaAsociación Argentina de NanomedicinasAsociación Argentina de Ciencia y Tecnología de Animales de LaboratorioHistochemical Society, 2019-11)Phosphodiesterases (PDE) belong to a super-family of enzymes that have multiple roles in the metabolism of nucleotides. These enzyme classes have played such a critical role as tools in the field of molecular biology, ... -
Fractional–order modeling and control of COVID-19 with shedding effect
(MDPI AG, 2023)A fractional order COVID-19 model consisting of six compartments in Caputo sense is constructed. The indirect transmission of the virus through susceptible populations by the shedding effect is studied. Equilibrium ... -
Some new estimates of integral inequalities and their applications
(National Academy of Sciences of Ukraine. Institute of Mathematics, 2024)We obtain several new integral inequalities in terms of fractional integral operators for the functions whose first derivatives satisfy either the conditions of the Lagrange theorem or the Lipschitz condition. In some ... -
Some refinements of the Hermite–Hadamard inequality with the help of weighted integrals
(National Academy of Sciences of Ukraine. Institute of Mathematics, 2023)By using the definition of modified (h, m, s)-convex functions of the second type, we present various refinements of the classical Hermite–Hadamard inequality obtained within the framework of weighted integrals. Throughout ... -
Integral inequalities for mappings whose derivatives are (h, m, s)−convex modified of second type via Katugampola integrals
(Universidad de Craiova. Departamentos de Matemáticas y de Ciencias de la Computación, 2022)In this paper, using the definition of functions (h,m,s)-convex modified of second type, various extensions of the classic Hermite-Hadamard Inequality are obtained using Katugampola integrals. In addition, we show that ... -
Some extensions of the Hermite-Hadamard inequalities for quasi-convex functions via weighted integral
(Universidad Católica del Norte, 2023)In this note, starting with a lemma, we obtain several extensions of the well-known Hermite-Hadamard inequality for convex functions, using generalized weighted integral operators. -
On generalizations of integral inequalities
(Universidad Estatal de Petrozavodsk, 2022)In the present study, several new generalized integral inequalities of the Hadamard and Simpson-type are obtained. The results were obtained for functions whose first and third derivatives are either convex or satisfy ... -
Classification of Argentinean Sauvignon blanc wines using UV spectroscopy and chemometric methods
(Institute of Food Technologists, 2013)Argentina is an important worldwide wine producer. In this country, there are several recognizable provinces that produce Sauvignon blanc wines: Neuquén, Río Negro, Mendoza, and San Juan. The analysis of the provenance ... -
South American snake venoms with abundant neurotoxic components. Composition and toxicological properties. A literature review
(Elsevier B.V., 2021)In South America there are three snake genera with predominantly neurotoxic venoms: Crotalus, Micrurus and Hydrophis, which include nine species/subspecies, 97 species and a single marine species, respectively. ... -
Physicochemical and biological characterization of nanovenoms, a new tool formed by silica nanoparticles and Crotalus durissus terrificus venom
(Elsevier B.V., 2020)Nanoparticles (NPs) are being studied due to their potential use as therapeutic and immunomodulatory tools, including their ability to transport antigens with the aim to induce a specific immune response. The production of ... -
Interacción entre poblaciones de Triatoma infestans y Triatoma sordida
(Universidade de São Paulo. Facultad de Salud Pública, 1994)Para conocer si se producía algún tipo de interacción entre poblaciones de Triatoma infestans y Triatoma sordida que convivían en una unidad experimental y explotaban el mismo recurso alimentario (ave) se las estudió ... -

Efecto de un tratamiento térmico sobre la calidad de pimientos cherry cortados refrigerados
(Universidad de la República. Facultad de Agronomía. Instituto Nacional de Investigación Agropecuaria, 2012-06)Se estudió el efecto de la aplicación de un tratamiento térmico (55 oC/60 s) sobre la evolución de parámetros de calidad de pimientos (Capsicum annuum, L. cv cherry) frescos cortados (descorazonados) almacenados durante ... -
Feeding ecology of two wild sympatric canids in protected areas of northeastern Argentina
(Zoological Society of London, 2024-11-18)The role of mesocarnivores in wildlife communities tends to be overlooked, which has led to a large gap in natural history knowledge. In northeastern Argentina, two mesocarnivore foxes, Cerdocyon thous and Lycalopex ... -
La metodología cuantitativa y su uso en América Latina
(Universidad de Chile, 2010)In this essay it is reviewed the main concepts of quantitative methodology, considering the historical context of science in Latin America and it is showed the areas of knowledge that use quantitative studies in Latin American ... -
La explicación como producto lógico o como producto de la praxis
(Universidad de Chile, 2001-09)Cada acto de explicación científica implica poner en juego inferencias, conceptos, datos empíricos y una serie de procesos que darán como producto, enunciados o proposiciones sujetas a procedimientos de validación. -
Cytotoxicity and morphological analysis of cell death induced by Bothrops venoms from the northeast of Argentina
(Universidad Estatal Paulista. Centro de Estudios de Venenos y Animales Ponzoñosos, 2009-02)Bothrops snake venoms have been proved toxic to a variety of cell types, in both in vivo and in vitro models. Studies on the pharmacological actions of Bothrops venoms from Argentina are relatively scarce and the direct ... -
