Aureliano in Cisalpina. I riflessi delle invasioni alamanniche nelle testimonianze archeologiche
2006
Le scarse testimonianze archeologiche risalenti al periodo delle invasioni alamanniche nel Nord della penisola italica rivelano, a un'analisi attenta, una situazione meno catastrofica di quella che è stata spesso descritta dagli studiosi che si sono occupati di quelle vicende.
Morphometric study on the effect of tenoxicam and its diluent in the venous endothelium, in rabbits
2001
Com o objetivo de avaliar pela morfometria o efeito do tenoxicam e do seu diluente no endotélio venoso, foram utilizados 48 coelhos (Oryctolagus cuniculus), brancos, da linhagem Nova Zelândia, machos, com idade acima de 10 semanas, com peso variando entre 2.350 e 3.500 gramas, divididos em dois grupos, denominados Experimento e Controle, que foram observados nos tempos de 6, 12 e 24 horas. Administrou-se nas venae auriculares dextra e sinistra, diluente ou tenoxicam/diluente no Grupo Experimento e cloreto de sódio a 0,9% no Grupo Controle. Não se constatou diferença estatisticamente significante entre o peso dos animais do Grupo Experimento e do Grupo Controle, antes da realização do proced…
Developments in Amphibian Parental Care Research : History, Present Advances, and Future Perspectives
2020
Despite rising interest among scientists for over two centuries, parental care behavior has not been as thoroughly studied in amphibians as it has in other taxa. The first reports of amphibian parental care date from the early 18th century, when Maria Sibylla Merian went on a field expedition in Suriname and reported frog metamorphs emerging from their mother's dorsal skin. Reports of this and other parental behaviors in amphibians remained descriptive for decades, often as side notes during expeditions with another purpose. However, since the 1980s, experimental approaches have proliferated, providing detailed knowledge about the adaptive value of observed behaviors. Today, we recognize mo…

Mecanismos Bioquímicos y Moleculares de la Neurodegeneración en la Enfermedad de Alzheimer
2023
La enfermedad de Alzheimer se caracteriza por la presencia de placas amiloideas, hiperfosforilación de la proteína TAU e incremento de la inflamación cerebral. El uso de modelos animales de experimentación, como APP/PS1 (proteína precursora de amiloide/presenilina 1), permite observar los cambios producidos tanto a nivel de bioquímico como de biología molecular. Las células encargadas de intervenir en el proceso inflamatorio cerebral son los astrocitos y la microglía. Los resultados de esta tesis nos indican que los cambios en las quimiocinas y los receptores de quimiocinas son importantes debido a la implicación que podrían tener en la inflamación relacionada con la enfermedad de Alzheimer…
First gas and thermal measurements at the frequently erupting Gamalama volcano (Indonesia) reveal a hydrothermally dominated magmatic system
2020
Abstract The first gas and thermal measurements at the summit of the Gamalama volcano indicate that the system is dominated by hydrothermal processes. This is highlighted by the prevalence of H2S over SO2 (H2S/SO2 = 2–8), a high CO2/SO2 ratio (76–201), and a low heat transfer (3.0 MW) to the surface. A relative variation in gas composition is observed along the degassing fracture zone, possibly due to partial S scrubbing. Despite this surface hydrothermal signature, the system exhibits high gas equilibrium temperatures (425–480 °C), indicating that fluids are not exclusively derived from a boiling hydrothermal aquifer, but also sourced by cooling and crystallizing basaltic magma at deep tha…
Extraction of lipids from microalgae using classical and innovative approaches
2022
Microalgae, as a photosynthetic autotrophic organism, contain a variety of bioactive compounds, including lipids, proteins, polysaccharides, which have been applied in food, medicine, and fuel industries, among others. Microalgae are considered a good source of marine lipids due to their high content in unsaturated fatty acid (UFA) and can be used as a supplement/replacement for fish-based oil. The high concentration of docosahexaenoic (DHA) and eicosapentaenoic acids (EPA) in microalgae lipids, results in important physiological functions, such as antibacterial, anti-inflammatory, and immune regulation, being also a prerequisite for its development and application. In this paper, a variety…
Fascioliasis in Llama, Lama glama, in Andean Endemic Areas: Experimental Transmission Capacity by the High Altitude Snail Vector Galba truncatula and…
2021
Simple Summary The infection by the liver fluke Fasciola hepatica in South American camelids, mainly llamas and alpacas, has been the focus of many studies. However, their capacity to participate in the transmission of the disease and their potential reservoir role in human or animal endemic areas have never been studied. Therefore, all development stages of an isolate from Argentine llama of the high Andean plateau have been experimentally investigated, from egg embryogenesis to metacercarial infectivity, by using the vector snail Galba truncatula from the high altitude Bolivian Altiplano human hyperendemic area. Although eggs shed by llamas may successfully develop until the adult stage i…
Experimental evidence of pharmacological management of anchorage in Orthodontics: A systematic review
2015
Introduction: Orthodontic anchorage is one of the most challenging aspects of Orthodontics. Preventing undesired movement of teeth could result in safer and less complicated orthodontic treatment. Recently, several reviews have been published about the effects of different molecules on bone physiology and the clinical side effects in Orthodontics. However, the effects of local application of these substances on the rate of orthodontic tooth movement have not been assessed.Objectives: The aim of this research was to analyze the scientific evidence published in the literature about the effects of different molecules on orthodontic anchorage.Methods: The literature was systematically reviewed …
The frequent exacerbator in real-life: an analysis of the DACCORD study
2019
Introduction: Exacerbation prevention is a major treatment goal in COPD. Hence, exacerbations are a decisive diagnostic and prognostic factor when it comes to therapy. The non-interventional prospective DACCORD study was following COPD patients for 2 years. Here, we compare patients with frequent exacerbations, non-frequent exacerbations and no exacerbations in the 6 months prior to study entry. Methods: DACCORD recruited COPD patients following a change or initiation of COPD maintenance. Data collected at baseline and every 3 months include exacerbations and COPD medication use. COPD Assessment Test (CAT) data were collected anually. Results: Out of 6527 patients, 7.1% were frequent exacer…
