Prototipo funcional de un sistema de detección de caídas basado en la plataforma CIAA

Las caídas son la principal causa de lesiones en personas mayores de 65 años. En este trabajo se describe el prototipo de un dispositivo capaz de detectar la caída de una persona y dar alerta a un centro de monitoreo y/o familiares. Si bien en la actualidad pueden encontrarse en el mercado soluciones similares, las mismas no son de fabricación nacional. El dispositivo descripto en este artículo permitirá contar con un detector de caídas de bajo costo de suma utilidad tanto para adultos mayores como para personas con movilidad reducida. Con él, se busca dar solución a las consecuencias adversas que se presentan al no detectar una caída rápidamente a través de un aparato totalmente desarrollado en Argentina.VII Workshop Procesamiento de Señales y Sistemas de Tiempo Real (WPSTR).Red de Universidades con Carreras en Informática (RedUNCI

cAMP Response Element-Binding Protein Controls the Appearance of Neuron-Like Traits in Chorion Mesenchymal Cells

Mesenchymal stromal cells (MSC) from bone marrow have been reported to undergo the initial phases of neural differentiation in response to an increase of intracellular cAMP. We investigated the possibility that a similar effect applies to chorion-derived MSC

Defining the Critical Hurdles in Cancer Immunotherapy

ABSTRACT: Scientific discoveries that provide strong evidence of antitumor effects in preclinical models often encounter significant delays before being tested in patients with cancer. While some of these delays have a scientific basis, others do not. We need to do better. Innovative strategies need to move into early stage clinical trials as quickly as it is safe, and if successful, these therapies should efficiently obtain regulatory approval and widespread clinical application. In late 2009 and 2010 the Society for Immunotherapy of Cancer (SITC), convened an "Immunotherapy Summit" with representatives from immunotherapy organizations representing Europe, Japan, China and North America to discuss collaborations to improve development and delivery of cancer immunotherapy. One of the concepts raised by SITC and defined as critical by all parties was the need to identify hurdles that impede effective translation of cancer immunotherapy. With consensus on these hurdles, international working groups could be developed to make recommendations vetted by the participating organizations. These recommendations could then be considered by regulatory bodies, governmental and private funding agencies, pharmaceutical companies and academic institutions to facilitate changes necessary to accelerate clinical translation of novel immune-based cancer therapies. The critical hurdles identified by representatives of the collaborating organizations, now organized as the World Immunotherapy Council, are presented and discussed in this report. Some of the identified hurdles impede all investigators, others hinder investigators only in certain regions or institutions or are more relevant to specific types of immunotherapy or first-in-humans studies. Each of these hurdles can significantly delay clinical translation of promising advances in immunotherapy yet be overcome to improve outcomes of patients with cancer

Twenty-three unsolved problems in hydrology (UPH) – a community perspective

This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation through on-line media, followed by two workshops through which a large number of potential science questions were collated, prioritised, and synthesised. In spite of the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work. Questions remain focussed on process-based understanding of hydrological variability and causality at all space and time scales. Increased attention to environmental change drives a new emphasis on understanding how change propagates across interfaces within the hydrological system and across disciplinary boundaries. In particular, the expansion of the human footprint raises a new set of questions related to human interactions with nature and water cycle feedbacks in the context of complex water management problems. We hope that this reflection and synthesis of the 23 unsolved problems in hydrology will help guide research efforts for some years to come

Dataset for surface spectral emissivity retrieval

We provide two databases, one for clear sky conditions and another for cloudy sky conditions, for both January and July 2021. Each database consists of input files for the CLAIM (CLouds and Atmospheric Inversion Module) code, as described in Sgheri et al. 2022, as well as output files. The input files contain data regarding the surface, atmospheric composition, and potential clouds. Additionally, the output files encompass computed variables essential for our analysis, including errors, precipitable water vapor, surface temperature, and thermal contrast

Generation of a human immunodeficiency virus type 1 chronically infected monkey B cell line expressing low levels of endogenous TRIM5alpha.

Several innate cellular antiviral factors exist in mammalian cells that prevent the replication of retroviruses. Among them, the tripartite motif protein (TRIM)5alpha has been shown to block human immunodeficiency virus type 1 (HIV-1) infection in several types of Old World monkey cells. Here we report a novel HIV-1 chronically infected monkey B cell line, F6/HIV-1, characterized by very low levels of TRIM5alpha expression that allows HIV-1 to overcome the restriction. Virus produced by F6/HIV-1 cells fails to infect monkey cells but retains the ability to infect human peripheral blood mononuclear cells (PBMCs) and T cell lines, although with a reduced infectivity compared to the input virus. Ultrastructural analyses revealed the presence of budding virions at the F6/HIV-1 cells plasma membrane characterized by a typical conical core shell. To our knowledge F6/HIV-1 is the first monkey cell line chronically infected by HIV-1 and able to release infectious particles thus representing a useful tool to gain further insights into the molecular mechanisms of HIV-1 pathogenesis
