2018
Este análisis situacional de la claridad y calidad de las notas explicativas en los estados financieros bajo IFRS (Obligatory Disclosure), pretende entregar claridad acerca de la calidad de la información entregada en las notas explicativas para 4 normas de Información Contable, claves en la información financiera en los países de la región, que son la NIC 2; Notas referente a Inventarios, NIC 16; Notas referente a Propiedad Planta y Equipos, NIC 37; Notas referente a Provisiones, y NIC 38; Notas referente a Activos Intangibles. Adicionalmente, este trabajo estudia la brecha de expectativas (Expectation Gaps) que existe en la información entregada en las notas de los estados financieros par…
Análisis y reingeniería de procesos en una empresa prestadora de servicios
2013
La globalización e internacionalización de los mercados, así como el aumento de la competencia arrastran a las organizaciones a plantearse cambiar sus estrategias de negocios. En este sentido, el presente estudio tiene por objeto mejorar el sistema de costes y gestión en una Autoridad Portuaria, mediante la implantación de un sistema de costes y gestión basado en las actividades (ABC/ABM). Con ello, se pretende dar respuesta a la necesidad que tenía esta entidad de adaptar su sistema de información interna a estas nuevas exigencias del mercado obteniendo, por consiguiente, una información de mayor calidad para lograr una gestión estratégica de sus costes.
Contra la patologización intensiva en términos de derechos humanos: Activismo gordo en Argentina
2020
This work addresses the way in which Argentine Fat Activism has developed, in recent years, the demand for depathologization of fatness, taking elements from critical discourses on the health of fat people to frame them in a perspective typical of the Human Rights. First, the contemporary fat body is described in terms of stigma and discrimination, especially in the health field. Then, they refer to a series of critical positions on the pathologization and medicalization of fatness from the biomedical perspective, Fat Studies and Fat Activism. Lastly, a series of interventions that the Argentine activist collective Taller Hacer la Vista Gorda produced between 2017 and 2020 were considered, …
Values for αβ and γδ T-lymphocytes and CD4+, CD8+, and CD56+ subsets in healthy adult subjects: Assessment by age and gender
2012
Background: Normal reference values in healthy subjects for T-lymphocytes for both types of receptors, αβ and γδ, and their subsets are yet to be defined. The aim of this study was to measure peripheral blood αβ and γδ total T-lymphocytes and their subsets in a population of healthy subjects, in order to obtain valid reference values for studies in human pathology. Methods: We studied a total of 157 healthy subjects, 78 men and 79 women, establishing their levels of CD3+, CD4+, CD8+, CD56+, αβCD3+, αβCD3+CD4+, αβCD3+CD8+, αβCD3+CD56+, γδCD3+, γδCD3+CD4−CD8−, γδCD3+CD8+, and γδCD3+CD56+ T-cells by flow cytometry. The T-cell subsets were compared for different age and gender groups. Results: …
Neurochemical alterations in women with borderline personality disorder and comorbid attention-deficit hyperactivity disorder
2010
Borderline personality disorder (BPD) is associated with structural and functional brain changes. Recent models and findings refer to alterations of glutamate and total N-acetylaspartate (tNAA) in this condition.Absolute quantities of tNAA, creatine, glutamate, glutamine, myoinositol and total choline were measured using 3 Tesla magnetic resonance spectroscopy of the left anterior cingulate cortex and the left cerebellum in 14 unmedicated women with BPD and comorbid attention-deficit hyperactivity disorder (ADHD) and 18 healthy women. Both groups were matched with respect to age, education and premorbid intelligence.In the anterior cingulate, we found significantly higher tNAA and glutamate…
Reduced interhemispheric structural connectivity between anterior cingulate cortices in borderline personality disorder
2008
Functional and structural alterations of the anterior cingulate cortex (ACC), a key region for emotional and cognitive processing, are associated with borderline personality disorder (BPD). However, the interhemispheric structural connectivity between the left and right ACC and between other prefrontal regions in this condition is unknown. We acquired diffusion-tensor imaging data from 20 healthy women and 19 women with BPD and comorbid attention-deficit hyperactivity disorder (ADHD). Interhemispheric structural connectivity between both sides of the ACC, dorsolateral prefrontal cortices and medial orbitofrontal cortices was assessed by a novel probabilistic diffusion tensor-based fiber tra…
miR-155 regulative network in FLT3 mutated acute myeloid leukemia
2015
Abstract Background Acute myeloid leukemia (AML) represents a heterogeneous disorder with recurrent chromosomal alterations and molecular abnormalities. Among AML with normal karyotype (NK-AML) FLT3 activating mutation, internal tandem duplication (FLT3-ITD), is present in about 30% of patients, conferring unfavorable outcome. Our previous data demonstrated specific up-regulation of miR-155 in FLT3-ITD+ AML. miR-155 is known to be directly implicated in normal hematopoiesis and in some pathologies such as myeloid hyperplasia and acute lymphoblastic leukemia. Methods and results To investigate about the potential influence of miR-155 de-regulation in FLT3-mutated AML we generated a transcrip…
Calf Blood Compound (CFC) and Homeopathic Drug Induce Differentiation of Primary Human Skeletal Muscle Cells.
2019
AbstractThe use of injections to treat structural muscle injuries is controversially discussed. In our controlled in vitro study, we investigated the biological impact of Actovegin and Traumeel alone and in combination on primary human skeletal muscle cells. Cells were characterized by immunofluorescence staining for myogenic factor 5 (Myf5) and MyoD, and cultured with or without Actovegin and / or Traumeel. The effects of these agents were assayed by cell viability and gene expression of the specific markers MyoD, Myf5, neural adhesion molecule (NCAM), and CD31. Myotube formation was determined by myosin staining. Neither Actovegin nor Traumeel showed toxic effects or influenced cell viabi…
KIAA0556 is a novel ciliary basal body component mutated in Joubert syndrome
2015
Background Joubert syndrome (JBTS) and related disorders are defined by cerebellar malformation (molar tooth sign), together with neurological symptoms of variable expressivity. The ciliary basis of Joubert syndrome related disorders frequently extends the phenotype to tissues such as the eye, kidney, skeleton and craniofacial structures. Results Using autozygome and exome analyses, we identified a null mutation in KIAA0556 in a multiplex consanguineous family with hallmark features of mild Joubert syndrome. Patient-derived fibroblasts displayed reduced ciliogenesis potential and abnormally elongated cilia. Investigation of disease pathophysiology revealed that Kiaa0556-/- null mice possess…
Functional profile of cytomegalovirus (CMV)-specific CD8+ T cells and kinetics of NKG2C+ NK Cells associated with the resolution of CMV DNAemia in al…
2011
Immune mechanisms involved in control of cytomegalovirus (CMV) infection in the allogeneic stem cell transplantation setting have not been fully disclosed. CMV pp65 and IE-1-specific CD8(+) T cells expressing IFN-γ, TNF-α, and CD107a, alone or in combination, and NKG2C(+) NK cells were prospectively enumerated during 13 episodes of CMV DNAemia. The expansion of monofunctional and polyfunctional CD8(+) T cells was associated with CMV DNAemia clearance. The size and functional diversity of the expanding CD8(+) T-cell population was greater in self-resolved episodes than in episodes treated with antivirals. These differences were related to the magnitude of expansion of cognate antigen IFN-γ C…
