Growth hormone replacement in adults:Real-world data from two large studies in US and Europe

2020

Objective: This report describes the effectiveness and safety of growth hormone replacement in 3180 adult patients with growth hormone deficiency followed-up for 0.0–12.2 years in two completed, complementary, non-interventional, multicentre studies, NordiNet® International Outcome Study (IOS) (NCT00960128) and the American Norditropin® Studies: Web-Enabled Research (ANSWER) Program (NCT01009905). Design: In both studies, Norditropin® (somatropin; Novo Nordisk A/S, Denmark) was administered at the discretion of the treating physician and according to routine practice. We present data on baseline characteristics, growth hormone dose, safety data and change from baseline in waist circumferenc…

The contribution of the European Society for Soil Conservation (ESSC) to scientific knowledge, education and sustainability

2019

Soil is an integral component of the global environmental system which supports the quality and diversity of terrestrial life on Earth. Therefore, it is vital to consider the processes and impacts of soil degradation on society, especially on the provision of environmental goods and services, including food security and climate change mitigation and adaptation. Scientific societies devoted to soil science play significant roles in reducing soil degradation and promoting soil conservation by advancing scientific knowledge, education and environmental sustainability. The ESSC was founded on 4 November 1988, with the aims to: 1. Support research on soil degradation, soil protection and soil an…

Salmon (Salmo salar) side streams as a bioresource to obtain potential antioxidant peptides after applying pressurized liquid extraction (PLE)

2021

The pressurized liquid extraction (PLE) technique was used to obtain protein extracts with antioxidant capacity from salmon muscle remains, heads, viscera, skin, and tailfins. A protein recovery percentage ≈28% was obtained for all samples except for viscera, which was ≈92%. These values represented an increase of 1.5–4.8-fold compared to stirring extraction (control). Different SDS-PAGE profiles in control and PLE extracts revealed that extraction conditions affected the protein molecular weight distribution of the obtained extracts. Both TEAC (Trolox equivalent antioxidant capacity) and ORAC (oxygen radical antioxidant capacity) assays showed an outstanding antioxidant activity for viscer…

Accelerated Solvent Extraction and Pulsed Electric Fields for Valorization of Rainbow Trout (Oncorhynchus mykiss) and Sole (Dover sole) By-Products: …

2021

Fishery by-products are rich in biologically active substances and the use of green and efficient extraction methods to recover these high-added-value compounds is of particular importance. In this study, head, skin and viscera of rainbow trout and sole were used as the target matrices and accelerated solvent extraction (ASE) (45–55 °C, 15 min, pH 5.2–6.8, 103.4 bars) and pulsed electric fields (PEF) (1–3 kV/cm, 123–300 kJ/kg, 15–24 h) were applied as extraction technologies. The results showed that ASE and PEF significantly increased the protein extract efficiency of the fish by-products (p < 0.05) by up to 80%. SDS-PAGE results showed that ASE and PEF treatments changed the molecular size…

Shell matrices of recent rhynchonelliform brachiopods: microstructures and glycosylation studies.

2007

ABSTRACTLike most metazoan biomineralisations, the brachiopod shell is the end product of a biologically controlled calcification process. The main agent of the control is the extracellular matrix, which is secreted by the outer mantle epithelium. This matrix mediates the calcification process by allowing crystal nucleation and elongation in specific orientations and finally, by stopping crystal growth. The proteinaceous moiety of brachiopod shell matrices has been extensively studied. Less known are the post-translational modifications that occur in these matrices, in particular glycosylations. In this comparison of five species of Recent articulated brachiopods, the ratio of soluble to in…

Bias correction of dynamically downscaled precipitation to compute soil water deficit for explaining year-to-year variation of tree growth over north…

2017

This paper documents the accuracy of a post-correction method applied to precipitation regionalized by the Weather Research and Forecasting (WRF) Regional Climate Model (RCM) for improving simulated rainfall and feeding impact studies. The WRF simulation covers Burgundy (northeastern France) at a 8-km resolution and over a 20-year long period (1989–2008). Previous results show a strong deficiency of the WRF model for simulating precipitation, especially when convective processes are involved. In order to reduce such biases, a Quantile Mapping (QM) method is applied to WRF-simulated precipitation using the mesoscale atmospheric analyses system SAFRAN («Système d'Analyse Fournissant des Rense…

The Agr communication system provides a benefit to the populations of Listeria monocytogenes in soil

2014

International audience; In this study, we investigated whether the Agr communication system of the pathogenic bacterium Listeria monocytogenes was involved in adaptation and competitiveness in soil. Alteration of the ability to communicate, either by deletion of the gene coding the response regulator AgrA (response-negative mutant) or the signal pro-peptide AgrD (signal-negative mutant), did not affect population dynamics in soil that had been sterilized but survival was altered in biotic soil suggesting that the Agr system of L. monocytogenes was involved to face the complex soil biotic environment. This was confirmed by a set of co-incubation experiments. The fitness of the response-negat…

Impact des digestats de méthanisation sur la qualité biologique des sols agricoles : nécessité de générer de nouvelles données pour objectiver

2021

National audience; La méthanisation est une technologie basée sur la dégradation par des micro-organismes de la matière organique, en conditions contrôlées et en l'absence dioxygène. Cette dégradation aboutit à la production d'un biogaz utilisé comme énergie renouvelable et d'un co-produit riche en matière organique appelé digestat. Ce digestat est au cœur de nombreuses interrogations, concernant les impacts engendrés par son épandage sur les sols. Avec l'essor de la méthanisation, la recherche s'intéresse à ses effets, afin de conserver des sols de qualité.

Biofonctionnements des sols tropicaux et mode de gestion des terres

2000

L'effet de deux peuplements de nématodes phytoparasites a été étudié en conditions contrôlées sur la croissance du mil (#Pennisetum glaucum$). Les plants de mil (cv. IKMV 8201) ont été cultivés en pots sur du col collecté au Sud du Sénégal dans un champ cultivé (sol cultivé) et dans une jachère de 17 ans (sol de jachère). La moitié du sol de chacun des prélèvements à été stérilisée. Pour compenser l'effet de la stérilisation, six cycles de cultures de mil de deux mois ont été faits avant l'expérimentation. A l'issu de cette période, trois espèces ont été observées sur le sol cultivé non stérilisé : #Scutellonema cavanessi$, #Tylenchorhynchus gladiolatus$ et #Ditylenchus myceliophagus$, dans…
