Towards implementing climate services in Peru – The project CLIMANDES

CLIMANDES is a pilot twinning project between the National Weather Services of Peru and Switzerland (SENAMHI and MeteoSwiss), developed within the Global Framework for Climate Services of the World Meteorological Organization (WMO). Split in two modules, CLIMANDES aims at improving education in meteorology and climatology in support of the WMO Regional Training Center in Peru, and introducing user-tailored climate services in two pilot regions in the Peruvian Andes. Four areas were prioritized in the first phase of CLIMANDES lasting from 2012 to 2015 to introduce climate services in Peru. A demand study identified the user needs of climate services and showed that climate information must be reliable, of high-quality, and precise. The information should be accessible and timely, understandable and applicable for the users’ specific needs. Second, the quality of climate data was enhanced through the establishment of quality control and homogenization procedures at SENAMHI. Specific training and application of the implemented methods at stations in the pilot regions was promoted to ensure the sustainability of the work. Third, the specific work on climate data enabled the creation of a webpage to disseminate climate indicators among users. The forth priority of the project enhanced the broad communication strategy of SENAMHI through creation of a specialized network of journalists, diverse climate forums, and the establishment of a user database. The efforts accomplished within CLIMANDES improved the quality of the climate services provided by SENAMHI. The project hence contributed successfully to higher awareness and higher confidence in the climate information by SENAMHI.Por pare

Dynamic Community Detection into Analyzing of Wildfires Events

The study and comprehension of complex systems are crucial intellectual and scientific challenges of the 21st century. In this scenario, network science has emerged as a mathematical tool to support the study of such systems. Examples include environmental processes such as wildfires, which are known for their considerable impact on human life. However, there is a considerable lack of studies of wildfire from a network science perspective. Here, employing the chronological network concept -- a temporal network where nodes are linked if two consecutive events occur between them -- we investigate the information that dynamic community structures reveal about the wildfires' dynamics. Particularly, we explore a two-phase dynamic community detection approach, i.e., we applied the Louvain algorithm on a series of snapshots. Then we used the Jaccard similarity coefficient to match communities across adjacent snapshots. Experiments with the MODIS dataset of fire events in the Amazon basing were conducted. Our results show that the dynamic communities can reveal wildfire patterns observed throughout the year.Comment: 16 pages, 8 figure

Adenylyl Cyclase Plays a Regulatory Role in Development, Stress Resistance and Secondary Metabolism in Fusarium fujikuroi

The ascomycete fungus Fusarium fujikuroi (Gibberella fujikuroi MP-C) produces secondary metabolites of biotechnological interest, such as gibberellins, bikaverin, and carotenoids. Production of these metabolites is regulated by nitrogen availability and, in a specific manner, by other environmental signals, such as light in the case of the carotenoid pathway. A complex regulatory network controlling these processes is recently emerging from the alterations of metabolite production found through the mutation of different regulatory genes. Here we show the effect of the targeted mutation of the acyA gene of F. fujikuroi, coding for adenylyl cyclase. Mutants lacking the catalytic domain of the AcyA protein showed different phenotypic alterations, including reduced growth, enhanced production of unidentified red pigments, reduced production of gibberellins and partially derepressed carotenoid biosynthesis in the dark. The phenotype differs in some aspects from that of similar mutants of the close relatives F. proliferatum and F. verticillioides: contrary to what was observed in these species, ΔacyA mutants of F. fujikuroi showed enhanced sensitivity to oxidative stress (H2O2), but no change in heavy metal resistance or in the ability to colonize tomato tissue, indicating a high versatility in the regulatory roles played by cAMP in this fungal group

The role of apoptosis in autoantibody production

In normal conditions, the intracellular autoantigens reach the cell surface by apoptosis and are normally cleared by phagocytes without inflammation, nevertheless the lack of depuration of apoptotic material foster the autoantibody production in individuals genetically predisposed, equally defects in signaling, execution and malfunction of the apoptotic pathways may induce autoimmunity, in consequence apoptosis is another way of understanding the autoimmunity (1)..

Possible role of Hsp70 in autoantigens shuttling to dermo-epidermal junction in systemic lupus erythematosus

Under stress cells and tissues perform a series of physiologic adjustments, including the heat shock protein production (Hsp), these proteins play a role as molecular chaperons, they are divided in five main families: Hsp27, Hsp 60, Hsp70, Hsp90 and Hsp110 (1). Hsp are constitutively induced or expressed to support the correct folding of novel proteins or to refold damaged proteins (2). Hsp70 is the most representative member of Hsp family. It is largely distributed in the majority of eukaryotic cell compartments and interact with the cytoskeleton during translocation of proteins across membranes (3)

Ro60 and La ribonucleoproteins become self-aggregated by cell stress

Ro is a cellular particle composed by three ribonucleoproteins of 60, 54 and 52 kDa (1-3). Ro60 forms a complex with one of the 1-5 hYRNAs (4). Antigenic properties of Ro were described by Clark in 1969 using autoimmune sera (5), and it is broadly accepted that Ro is recognized by autoantibodies from patients with systemic lupus erythematosus (SLE), subacute cutaneous lupus erythematosus (SCLE), Sjögren’s syndrome (SS) and neonatal lupus (6). Complexes of Ro are involved in the transcription quality control of 5S rRNA, Ro60 bind the 5S rRNA inefficient transcribed to be eliminated (7, 8). Ro is expressed broadly in nucleus and cytoplasm of eukaryotic cells (9-11)
