Diptera, Ceratopogonidae, Dasyhelea necrophila Spinelli and Rodriguez, 1999: detection of eggs in ovitraps, in Uruguay

Ovitraps with eggs of Dasyhelea necrophila were detected at five localities in Uruguay during surveillance and control of Aedes aegypti. Relevant dates of oviposition in wild of this Ceratopogonidae species are included in addition to previous laboratory work on the species. Eggs of D. necrophila were deposited together with eggs of Culicidae and Psychodidae. These are the first records of the species from Uruguay.Fil: Martínez, María.

Incobotulinum booster injections in patients with spasticity and dystonia after stroke

Background.\u2013 Previous results in patients injected with abobotulinum toxin A and onabotulinum toxin A have shown that injection intervals shorter than 2 months may increase the risk for neutralising antibody formation and treatment non-response. As a result, for the last 10 years, we have adopted longer intervals to treat patients with spasticity and/or dystonia secondary to stroke. It has been showed that incobotulinum toxin A does not induce neutralising antibodies. Observations.\u2013 Methods.\u2013 Ten patients with spasticity and/or dystonia due to stroke underwent a booster injection one month after the first injection. The clinical results were compared to those previously obtained in the same 10 patients using a single injection. Secondary dystonia was evaluated using the Unified Dystonia Rating Scale (UDRS), while spasticity was evaluated according to the Modified Ashworth Scale (MAS). Results.\u2013 They showed that the booster injection protocol induced an improvement in 8 subjects. In the remaining 2 subjects, we did not find any difference between the results obtained using the single and the booster injection protocols. Conclusions.\u2013 The use of a booster injection improve the clinical outcome in patients with spasticity and/or dystonia after stroke, allowing an optimal treatment of those muscles that poorly responded to the first injection

Anticipating the Flood. Community-based cartography for disaster flood events in Argentina

Anticipando la Crecida Project (Anticipating the Flood) is an interdisciplinary project which deals with flood risk management strategies associated with intense rain events and southeasterly wind « sudestadas » in socio-economical vulnerable urban areas in Argentina. The objective of the current study is to use local knowledge through participatory activities to strengthen the phase of risk awareness of an early warning system by using cartography as a work tool. For this purpose, eleven workshops with adults and children were held between 2014 and 2017 in Buenos Aires metropolitan area and the towns of San Antonio de Areco and Santa Lucía. By helping communities articulate and communicate spatial knowledge through workshops, enable the possibility to advocate for a change. That change result in a new direction on how the community and stakeholders can act towards a flood event. Analysing community-based maps of 85 adults, flood theoretical models can be evaluated and perhaps improved. Additionally, overall 287 students between 10 and 17 years old learned about cartography and interacted with poster maps during the workshops held in different schoolsFil: Gatti, Ignacio Agustin.

Comprehensive phenotyping revealed transient startle response reduction and histopathological gadolinium localization to perineuronal nets after gadodiamide administration in rats

Gadolinium based contrast agents (GBCAs) are widely used in clinical MRI since the mid-1980s. Recently, concerns have been raised that trace amounts of Gadolinium (Gd), detected in brains even long time after GBCA application, may cause yet unrecognized clinical consequences. We therefore assessed the behavioral phenotype, neuro-histopathology, and Gd localization after repeated administration of linear (gadodiamide) or macrocyclic (gadobutrol) GBCA in rats. While most behavioral tests revealed no difference between treatment groups, we observed a transient and reversible decrease of the startle reflex after gadodiamide application. Residual Gd in the lateral cerebellar nucleus was neither associated with a general gene expression pathway deregulation nor with neuronal cell loss, but in gadodiamide-treated rats Gd was associated with the perineuronal net protein aggrecan and segregated to high molecular weight fractions. Our behavioral finding together with Gd distribution and speciation support a substance class difference for Gd presence in the brain after GBCA application

Evidence of protective effects of recombinant ADAMTS13 in a humanized model of sickle cell disease

Sickle cell disease (SCD) is an inherited red blood cell disorder that occurs worldwide. Acute vaso-occlusive crisis is the main cause of hospitalization in patients with SCD. There is growing evidence that inflammatory vasculopathy plays a key role in both acute and chronic SCD-related clinical manifestations. In a humanized mouse model of SCD, we found an increase of von Willebrand factor activity and a reduction in the ratio of a disintegrin and metalloproteinase with thrombospondin type 1 motif, number 13 (ADAMTS13) to von Willebrand factor activity similar to that observed in the human counterpart. Recombinant ADAMTS13 was administered to humanized SCD mice before they were subjected to hypoxia/reoxygenation (H/R) stress as a model of vaso-occlusive crisis. In SCD mice, recombinant ADAMTS13 reduced H/R-induced hemolysis and systemic and local inflammation in lungs and kidneys. It also diminished H/R-induced worsening of inflammatory vasculopathy, reducing local nitric oxidase synthase expression. Collectively, our data provide for the firsttime evidence that pharmacological treatment with recombinant ADAMTS13 (TAK-755) diminished H/R-induced sickle cell-related organ damage. Thus, recombinant ADAMTS13 might be considered as a potential effective disease-modifying treatment option for sickle cell-related acute events

TiO2 nanorods doped with g-C3N4 – Polyethylene composite coating for self-cleaning applications

Visible-light-absorbing graphitic carbon nitride–TiO2 nanorod nanomaterials (g-C3N4@TiO2NR) were successfully immobilized using a one-step UVA-induced photocatalytic procedure on commercially obtained flexible low-density polyethylene (LDPE) films. Self-cleaning properties were evaluated in solid–liquid and solid–gas phases using malachite green as a model molecule under UV-A and visible light irradiation. For comparison purpose, LDPE films containing P25 TiO2 nanoparticles was prepared using the same synthetic strategy (P25/LDPE). Among the fabricated films, the g-C3N4@TiO2NR/LDPE films exhibited the highest photocatalytic activity both in solid–liquid and solid–gas phases after 120 min of visible light irradiation (λ > 455 nm) removing efficiently malachite green stains probably due to the attack of photoinduced reactive oxygen species (ROS) such as singlet oxygen (1O2), hydroxyl radical (•OH) and superoxide anion radical (O2−•). Furthermore, the g-C3N4@TiO2NR/LDPE films retained their visible-light-photoinduced photocatalytic properties after four reuse cycles. The g-C3N4@TiO2NR/LDPE films also exhibited significant visible-light-photoinduced hydrophilicity. The high visible-light-photoinduced photocatalytic capacity of g-C3N4@TiO2NR/LDPE films was found to be related to the textural and electronic properties, superior visible-light absorption, and surface roughness of the films.Fil: Osorio Vargas, Paula Alejandra.
