Complex Regulatory Networks Governing Production of the Glycopeptide A40926

2018

Glycopeptides (GPAs) are an important class of antibiotics, with vancomycin and teicoplanin being used in the last 40 years as drugs of last resort to treat infections caused by Gram-positive pathogens, including methicillin-resistant Staphylococcus aureus. A few new GPAs have since reached the market. One of them is dalbavancin, a derivative of A40926 produced by the actinomycete Nonomuraea sp. ATCC 39727, recently classified as N. gerenzanensis. This review summarizes what we currently know on the multilevel regulatory processes governing production of the glycopeptide A40926 and the different approaches used to increase antibiotic yields. Some nutrients, e.g., valine, l-glutamine and mal…

The role of dalbavancin for Gram positive infections in the COVID-19 era: state of the art and future perspectives

2021

INTRODUCTION: The COVID-19 pandemic has dramatically challenged the national health systems worldwide in the last months. Dalbavancin is a novel antibiotic with a long plasmatic half-life and simplified weekly administration regimens, thus representing a promising option for the outpatient treatment of Gram-positive infections and the early discharge of hospitalized patients. Dalbavancin is approved for the treatment of acute bacterial skin and skin structure infections (ABSSSIs). Many preliminary data seem to support its use in other indications, such as osteomyelitis, prosthetic joint infections, and infective endocarditis.

Antioxidant Activity and Determination of Gallic Acid and Quercetin in Osyris alba L. Root Extract. The Root Oil Contains Essential Fatty Acids

2018

Osyris alba L. (Santalaceae) is a shrub that grows wildly in southern Europe, North Africa and South-west Asia. In Algeria, the decoction of the root bark of this plant has been used since ancient times in folk medicine by the local population in the region of the mountains of Béni- Snousse (South west of Tlemcen), as a fortifying, antianaemic and as an anti-inflammatory agent. The aim of this work was to evaluate the antioxidant activity of the phenolic compounds of the root by using DPPH, FRAP, TAC methods. Determination of the phenolic profile of the root extract was assessed using HPLC-DAD technique (High Performance Liquid Chromatography-Diode Array Detection). While the determination …

Sedimentary environment, lithostratigraphy and dating of sediment sequences from Arctic lakes Revvatnet and Svartvatnet in Hornsund, Svalbard

2016

Abstract The sedimentary environment, sediment characteristics and age-depth models of sediment sequences from Arctic lakes Revvatnet and Svartvatnet, located near the Polish Polar Station in Hornsund, southern Svalbard (77°N), were studied with a view to establishing a basis for paleolimnological climate and environmental reconstructions. The results indicate that catchment-to-lake hydroclimatic processes probably affect the transportation, distribution and accumulation of sediments in different parts of lakes Revvatnet and Svartvatnet. Locations with continuous and essentially stable sedimentary environments were found in both lakes between water depths of 9 and 26 m. We used several diff…

UAV and GPR Data Integration in Glacier Geometry Reconstruction: A Case Study from Irenebreen, Svalbard

2022

Although measurements of thickness and internal structure of glaciers are substantial for the understanding of their evolution and response to climate change, detailed data about polythermal glaciers, are scarce. Here, we present the first ground-penetrating radar (GPR) measurement data of Irenebreen, and high-resolution DEM and orthomosaic, obtained from unmanned aerial vehicle (UAV) photogrammetry. A combination of GPR and UAV data allowed for the reconstruction of the glacier geometry including thermal structure. We compare different methods of GPR signal propagation speed determination and argue that a common midpoint method (CMP) should be used if possible. Our observations reveal that…

El administrador testamentario ¿venganza póstuma?

2019

El objeto del presente estudio es poner de manifiesto la escasa regulación en el Código civil de la figura del administrador testamentario. Esta figura ha sido creada con la intención de proteger el patrimonio del hijo menor o incapacitado del testador. Sin embargo, esta figura puede provocar graves problemas cuandola persona designada para el cargo de administrador testamentario mantiene malas relaciones con el progenitor del menor que ha sido expresamente excluido de la administración de aquellos bienes transmitidos a título gratuito. En este trabajo analizaremos las distintas soluciones planteadas por la jurisprudencia y la doctrina para aplicar analógicamente los regímenes de otras figu…

La sentencia y su ejecución en el proyecto dominicano de ley sobre control judicial de la administración pública

2021

The regime of the execution of the sentence is analyzed, starting from the powers of declarative and executive substitution of the contentious-administrative judge. It begins with the reference to the constitutional guidelines of the administrative process. Then, the different modalities of judicial substitution are described in the types of sentences (declarative, constitutive and conviction) regulated in the project, to then refer to the regime of executive seizure of public goods. It ends by describing: the powers granted to the judge to agree indirect measures that assist with the execution of the judgment, the cases of impossibility of execution and the extension of the sentence to thi…

Flexibility in otherwise consistent non-breeding movements of a long-distance migratory seabird, the long-tailed skua

2017

Quantifying within- and between-individual variation in animal migration strategies is a first step towards our understanding of the ability of migrants to adjust to changes in the en - vironment. We studied consistency (or, conversely, flexibility) in movement patterns at large (>1000 km) to meso-scales (100−1000 km) during the non-breeding season of the long-tailed skua Stercorarius longicaudus, a long-distance migratory Arctic seabird, using light-based geolocation. We obtained 97 annual tracks of 38 individuals and quantified similarity between routes. Overall, tracks of the same individual were generally within about 200 to 300 km of their previous year’s route, and more similar than t…
