El sarcoma de Kaposi es un tumor linfoangioproliferativo descripto por primera vez en el año 1872 por Moritz Kaposi. Hay cuatro variantes clínicas, la forma clásica, la endémica, la iatrogénica asociada a trasplante o inmunosupresión y la epidémica asociada a SIDA, de la cual se hará referencia en esta publicación. Se describe un paciente varón de 31 años, al cual durante la misma internación se hace el diagnóstico de SIDA y de sarcoma de Kaposi.
In this work, the removal of different types of emerging pollutants (four perfluoroalkyl compounds, two preservatives, three surfactants and nine pharmaceutical compounds) from aqueous solution by adsorption onto two novel synthetic clays, a high-charge swelling mica (Na-Mica-4) and an organo-functionalized mica (C-Mica-4), was evaluated. Na-Mica-4 and C-Mica- 4 were prepared and characterized by X-Ray diffraction, Zeta potential, specific surface area, thermogravimetric analysis and transmission electron...
Inhibition of protease-driven MICA and MICB shedding enhances NK cell-mediated tumor immunity.
There are currently no biomarkers that predict hepatocellular carcinoma (HCC) risk in patients with hepatitis C virus (HCV)-related cirrhosis. We investigated the relationships among major histocompatibility complex (MHC) class I chain-related gene A (MICA) polymorphisms, plasma levels of soluble MICA (sMICA), and HCC risk in patients with HCV-related HCC. One hundred fifty-four HCV-related HCC patients, 93 HCV-related liver cirrhosis (LC) cases, and 244 healthy controls, all sampled from the native Sicilia...
Introducción: una ley exponencial se ha hallado para los sistemas dinámicos caóticos cardiacos, logrando cuantificar las diferencias entre dinámicas cardiacas normales y patológicas.Metodología: Se analizaron 120 registros electrocardiográficos, 40 correspondían a sujetos dentro de los límites de normalidad y 80 con diferentes patologías. Para cada holter se analizaron los atractores generados con los datos durante 18 horas y durante toda la dinámica. Se calculó la dimensión fractal del atrac...

We develop Magnetic Cytoskeleton Affinity (MiCA) purification, which allows for rapid isolation of molecular motors conjugated to large multivalent quantum dots, in miniscule quantities, which is especially useful for single-molecule applications. When purifying labeled molecular motors, an excess of fluorophores or labels is usually used. However, large labels tend to sediment during the centrifugation step of microtubule affinity purification, a traditionally powerful technique for motor purification. Thi...
Rheumatoid arthritis (RA) as an inflammatory autoimmune disease affects the synovial joints as well as other organs and tissues. Since aberrant expression of MIC molecules has been observed in RA patient, MIC genotypes might play certain roles in the development of RA.
Post-ischemic administration of 5-methoxyindole-2-carboxylic acid at the onset of reperfusion affords neuroprotection against stroke injury by preserving mitochondrial function and attenuating oxidative stress.
We previously reported that 5-methoxyindole-2-carboxylic acid (MICA) could induce preconditioning effect in the ischemic brain of rat. In the present study, we addressed the question of whether MICA could also trigger a postconditioning effect in ischemic stroke. To this end, MICA (100mgkg body weight) was injected intraperitoneally at the onset of 24 h reperfusion following 1 h ischemia in rat brain. Results indicate that stroked animals treated with MICA showed less brain infarction volume than that o...
INTRODUCCIONEl derrame pleural neoplásico (DPN) implica una enfermedad oncológica avanzada. La biopsia pleural por cirugía torácica endoscópica permite el diagnóstico en más del 90% de los casos y la instrumentación del espacio pleural complicado, mejorando los resultados de la técnica.MATERIAL Y METODOSe realizó un análisis retrospectivo de pacientes con DPN operados para la realización de una pleurodesis química con talco. Se formaron dos grupos, uno con derrame pleural neoplásico complicado...
Colorectal carcinoma (CRC) is one of the most common malignant cancers worldwide. The poor response of CRC to chemotherapy has whipped up the interest in targeted therapy with monoclonal antibodies for its potential efficiency. However, cetuximab, as one of the first-line targeted drugs in the treatment of CRC, has drug resistance and poor prognosis in clinic. To address this, a novel bispecific protein with CRC targeting and natural killer (NK) cell triggering was used for treatment. NK cell-mediated immun...
In spite of the frequency of chronic urticaria, there are no epidemiological studies on its prevalence in Argentina.
Research in the Mental Health field is essential not only in the academic area, but also in the patient care setting. Knowing the attitudes, knowledge and practices in research among psychiatrists allow for the design of interventions to promote their participation. The aim of this study is to explore the current situation of research among psychiatrists in Argentina. A cross sectional 26-question survey was applied between May-August 2014, anonymous and voluntary among psychiatrists and psychiatrists in tr...
Zika virus (ZIKV) vertical transmission may lead to microcephaly and other congenital anomalies. In March and April 2016, the first outbreak of ZIKV occurred in Argentina. The objective was to describe the surveillance of newborns with microcephaly and other selected brain anomalies in Argentina, and evaluation different etiologies.
Reproductive losses linked to an infectious etiology in bovine cattle are a major economic concern worldwide. In Argentina, more than 50% of abortion cases have unknown causes. Species belonging to Chlamydiaceae family are frequent etiologic agents of abortion around the world; however, there is yet no information on their prevalence in Argentina. The objective of this work was to identify Chlamydia spp., and particularly C. abortus in reproductive losses from bovine cattle in La Pampa, Argentina. Real time...

The aim of this study was to analyze the effects of individual low socioeconomic status (SES) and deprived geographical area (GA) on the occurrence of isolated cleft lip with or without cleft palate (CL±P) in Argentina.
In Argentina, like in the rest of the world, deinstitutionalization policies have been implemented. In our country, the shortage of epidemiologic data regarding admissions in mental health is a limitation for the discussion about how this changes should be implemented and its effect.

The new Sepsis-3 definitions have been scarcely assessed in low- and middle-income countries; besides, regional information of sepsis outcomes is sparse. Our objective was to evaluate Sepsis-3 definition performance in Argentina.
The present study aimed at investigating the timing of birth across the day in a rural population of indigenous and nonindigenous women in the province of Formosa, Argentina in order to explore the variation in patterns in a non-Western setting.
The solid-substrate-dependent structure and dynamics of molecules in a supported lipid bilayer (SLB) were directly investigated via atomic force microscopy (AFM) and single particle tracking (SPT) measurements. The appearance of either vertical or horizontal heterogeneities in the SLB was found to be strongly dependent on the underlying substrates. SLB has been widely used as a biointerface with incorporated proteins and other biological materials. Both silica and mica are popular substrates for SLB. Using ...
