Introduction: Time tracking of acute stroke assistance is crucial for treatment goals. Resources availability varies among centers. We aim to assess a low-cost mobile app's impact on collecting times in traditional hospital. Patients and Methods: Neurology consultants residents tested the application prototype voluntarily from July 14 September 30, 2021. A prospective observational study, based pre- post-implementation anonymous satisfaction surveys, was designed. While primary objective not...
Abstract A key step in the elimination of invading pathogens from body is covalent binding complement proteins C3b and C4b to their surface. However, many have evolved mechanisms avoid system host. Understanding how these work may lead more efficacious forms therapy. Here we provide an insight into molecular basis Streptococcus pyogenes binds human plasma C4b-binding protein (hC4BP), a regulatory molecule that decrease deposition on streptococcal We show surface molecules bind site hC4BP...
This paper describes a series of experiments designed to recover phosphorus and nitrogen from sewage in the form struvite (MgNH4PO4·6H2O), potential fertilizer. Nitrogen phosphate were recovered filtrate digested sludge dewatered at Arroyo del Soto Waste Water Treatment Plant (WWTP) (Madrid, Spain). A byproduct Spanish magnesite mining MgO production industry was used as magnesium source. The precipitating performance this compared that conventional chemical reagents such pure MgO....
<span>Durante las últimas décadas anomalías térmicas han sido más frecuentes y severas en el Caribe, quedando pocos arrecifes exentos de eventos masivos blanqueamiento (EMB). En Parque Nacional Los Roques, Venezuela, un archipiélago poco afectado previamente por EMB, la temperatura del agua a 5m profundidad alcanzó 30,85°C septiembre 2010, fue &gt;29,0°C entre mediados agosto primera semana noviembre cuatro arrecifes. El 72% 563 colonias escleractinios estaban blanqueadas o pálidas...
This study evaluated pollution levels in water and sediments of Península de Paraguaná related these with benthic macrofauna along a coastal area where the largest Venezuelan oil refineries have operated over past 60 years. For this, concentration heavy metals, hydrocarbon compounds community structure macrobenthos were examined at 20 sites distributed 40 km coastline for six consecutive years, which included windy calm seasons. The spatial variability organic inorganic showed considerably...
Healthy and diseased corals are threatened by different anthropogenic sources, such as pollution, a problem expected to become more severe in the near future. Despite fact that coastal pollution coral diseases might represent serious threat reef health, there is paucity of controlled experiments showing whether response healthy xenobiotics differs. In this study, we exposed Caribbean yellow band disease (CYBD)-affected Orbicella faveolata colonies 3 sublethal concentrations anthracene test...
Abstract In this study we examined the behaviour of biomarkers in corals combining reproductive status colonies and reef sites with different levels contamination. The content P450 P420 activities NADPH c reductase, glutathione S-transferase (GST), catalase (CAT) superoxide dimutase (SOD) were measured coral Siderastrea siderea at two marine parks. Parque Nacional Morrocoy (PNM) encompasses a continental ecosystem largely influenced by anthropogenic impacts. contrast, Archipielago Los Roques...
Cytochrome P450 was detected in the animal tissue of scleractinian corals Siderastrea siderea and Montastraea faveolata collected from a reef site on west coast Venezuela. The concentration these species (0.4–2.1 nmol mg–1 microsomal protein) similar to levels found other marine invertebrates, but higher than previously reported for organisms phylum Cnidaria. Maximum content samples during reproductive season S. siderea. These results confirm presence functional cytochrome two coral species....
El valor nutritivo del polen de los recursos botanicos explotados por las abejas meliferas es mucha importancia para la apicultura, fundamentalmente en zonas donde agricultura moderna causa reduccion diversidad recursos. Se determino el contenido proteina cruda 25 especies vegetales frecuentemente visitadas abejas. Los valores hallados variaron entre 14,5 y 41,5%, mayoria presentaron con mas 20% proteina, minimo aceptado una correcta nutricion En 10 12 que se analizo muestra encontro...
Venezuelan oil exploration and exploitation activities have been taking place since the 18th century. These long-term are closely related to heavy metal contamination because of increasing input toxic pollutants. Variations in concentrations can cause, among other things, changes distribution patterns, alterations biogeochemical cycles, increments environmental biological risks. The need for a complete baseline on along coast is critical. For this reason, we present concentrations,...
