Film Dressings Based on Hydrogels: Simultaneous and Sustained-Release of Bioactive Compounds with Wound Healing Properties
(MDPI, 2019)This research proposes the rational modeling, synthesis and evaluation of film dressing hydrogels based on polyvinyl alcohol crosslinked with 20 different kinds of dicarboxylic acids. These formulations would allow the ... -
Filtering of Data-Driven Gene Regulatory Networks Using Drosophila melanogaster as a Case Study
(FRONTIERS MEDIA SA, 2021-07-28)Gene Regulatory Networks (GRNs) allow the study of regulation of gene expression of whole genomes. Among the most relevant advantages of using networks to depict this key process, there is the visual representation of large ... -
El fin de la protección gonadal en radiografía de pelvis: una revisión
(Sociedad Chilena de Radiología, 2020)La protección gonadal ha sido durante largo tiempo un importante factor para abordar el requisito “tan bajo como sea razonablemente posible” ALARA. El presente artículo realiza una revisión sistemática sobre la utilidad ... -
Finite mixture-of-gamma distributions: estimation, inference, and model-based clustering
(SPRINGER HEIDELBERG, 2019)Finite mixtures of (multivariate) Gaussian distributions have broad utility, including their usage for model-based clustering. There is increasing recognition of mixtures of asymmetric distributions as powerful alternatives ... -
Fire history in Andean Araucaria-Nothofagus forests: coupled influences of past human land-use and climate on fire regimes in north-west Patagonia
(CSIRO, 2020)Historical fire regimes are critical for understanding the potential effects of changing climate and human land-use on forest landscapes. Fire is a major disturbance process affecting the Andean Araucaria forest landscape ... -
First Genetic Record of a Strap-Toothed Beaked Whale (Mesoplodon layardii) Stranding in Chile
(Chile. Universidad Mayor, 2020)Of all the cetacean families, the Ziphiidae are one of the most enigmatic (MacLeod, 2018). They are the second most diverse family after the Delphinidae (Dalebout et al., 2002). They dive very deep for prolonged periods, ... -
First record of fossil procyonid (Mammalia, Carnivora) from Uruguay
(PERGAMON-ELSEVIER SCIENCE LTD, 2019)Procyonids were the first carnivorans that arrived from North America to South America during the late Miocene, before the full emergence of the Panama Isthmus. In South America, this family comprises five living genera ... -
First Release of the Bacterial Biobank of the Urban Environment (BBUE)
(AMER SOC MICROBIOLOGY, 2018)Metagenomics is providing a broad overview of bacterial functional diversity; however, culturing and biobanking are still essential for microbiology. Here, we present the Bacterial Biobank of the Urban Environment (BBUE), ... -
