Water retention characteristics of substrates containing biochar and compost as peat and perlite replacements for ornamental plant production
2021
In Italy peat and perlite are commonly used as growth substrates in ornamental plant nurseries. Requests for ecologically sustainable growth substrates have recently focused research on the study of new media. In this context, biochar and compost, by-products of other production chains, may play a relevant role. Four growth substrates were prepared by mixing (v/v) different porous matrices including a 2-mm sieved sandy loam soil namely: 50% peat and 50% perlite (PPr), 50% compost and 50% biochar (CB), 25% peat, 25% perlite, 25% compost and 25% biochar (PPrCB) and 25% peat, 25% compost and 50% mineral soil (PCM). Water retention curves of porous matrices and growth substrates were determined…
The Impact of the International Cooperation On Familial Hypercholesterolemia Screening and Treatment: Results from the ScreenPro FH Project
2019
Purpose of Review Familial hypercholesterolemia (FH) is often perceived and described as underdiagnosed and undertreated, though effective treatment of FH is available. Owing to the mentioned facts, it is ever more imperative to screen and treat FH patients. Subsequent to the identification of patients, the project focuses on the improvement of their prognoses. The ScreenPro FH project was established as a functional international network for the diagnosis, screening, and treatment of FH. Individual countries were assigned goals, e.g., to define the actual situation and available treatment. With “central support,” more centers and countries participated in the project. Subsequently, individ…
Physical Activity Among Children With Congenital Heart Defects in Germany: A Nationwide Survey
2020
Objective: In children with congenital heart defects (CHD), a sedentary lifestyle should be avoided and usually WHO recommendations on physical activity (PA) are supposed to be followed. In order to obtain representative data of the actual amount of PA (and potential influencing factors) in children with CHD we performed a nationwide online survey.Methods: All patients aged 6–17 years registered in the German National Register for CHD were contacted by email and asked to participate in the survey using the comprehensive questionnaire of the “Motorik-Modul” from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), thus allowing the comparison with a repres…
Diet and prey size spectrum of pikeperch in lakes in central Finland
2004
The stomach content of pikeperch Sander lucioperca was studied in 24 lakes in central Finland. The most important prey species was smelt Osmerus eperlanus then perch Perca fluviatilis. The proportion of cyprinids as prey increased with pikeperch total length (LT) and lake phosphorus content. Prey L T and pikeperch L T correlated positively, but the prey-to-predator size ratio correlated negatively with pikeperch L T .
Gastric evacuation rate of burbot fed single-fish meals at different temperatures
1997
The gastric evacuation rates of burbot Lota lota, fed a single meal of vendace, Coregonus albula, were measured in the laboratory at five temperatures (1·3, 2·6, 4·8, 9·4 and 12·6° C). Gastric evacuation rate increased exponentially with increasing temperatrure, but the results suggest that gastric evacuation rates of burbot at low temperatures are lower than those of other freshwater fish species. Temperature and the ratio of meal weight to burbot weight were the most important factors affecting gastric evacuation rate. There was no significant difference in gastric evacuation rate between three different prey species: vendace, perch Perca fluviatilis, and smelt Osmerus eperlanus.
Diet composition and seasonal feeding patterns of a freshwater ringed seal (Pusa hispida saimensis)
2014
The Saimaa ringed seal (Pusa hispida saimensis) is one of the few freshwater seal populations worldwide. The major conservation issue of this critically endangered population is bycatch mortality. We used digestive tract content and stable isotopes (d 13 Ca ndd 15 N) to estimate the diet and seasonal feeding patterns for gaining better understanding of the seals feeding habits and potential conservation implications. The diet was similar across age groups. Altogether 15 fish species were identified and the most important were smelt (Osmerus eperlanus), ruff (Gymnocephalus cernuus), perch (Perca fluviatilis), vendace (Coregonus albula )a nd cyprinids. The high d 15 N values suggested that th…
Mitochondrial Toxicity in HAART: An Overview of In Vitro Evidence
2011
The combined antiretroviral therapeutic approach currently employed for the treatment of HIV infection, known as Higly Active Antiretroviral Therapy (HAART), has dramatically reduced AIDS-related morbidity and mortality. However, the adverse reactions associated with the long term use of this therapy have now become a major issue and researchers have focused on understanding the cellular mechanisms underlying these drug-induced detrimental effects which englobe a large list of different events including rash and hypersensibility reactions, hepatotoxicity, metabolic disturbances including lipodystrophy, and other metabolic syndrome-like disturbances such as hyperlactatemia, hyperlipedimia, i…
“European Panel on Low Density Lipoprotein (LDL) Subclasses”: A Statement on the Pathophysiology, Atherogenicity and Clinical S…
2011
Aim of the present Consensus Statement is to provide a comprehensive and up to-date document on the pathophysiology, atherogenicity and clinical significance of low density lipoproteins (LDL) subclasses. We sub-divided our Statement in 2 sections: section I discusses the pathophysiology, atherogenicity and measurement issues, while section II is focused on the effects of drugs and lifestlyle modifications. Suggestions for future research in the field are highlighted at the end of section II. Each section includes Conclusions.
Regulatory evaluation of Glybera in Europe — two committees, one mission
2013
Representing the first gene therapy to be approved in the Western world, alipogene tiparvovec (Glybera; Uniqure) has recently been said to have had a “substantial impact from a regulatory perspective” (Nature Rev. Drug Discov. 11, 664; 2012) 1 . The therapy was granted marketing authorization in the European Union for the treatment of lipoprotein lipase deficiency, which results in a clinically heterogeneous condition with a risk of potentially life-threatening pancreatitis 2 , at the end of 2012. The decision followed a positive opinion by the European Medicines Agency (EMA)’s Committee for Medicinal Products for Human Use (CHMP) 3
In situ study of the phase transition in Bi2Ti4O11
1995
Abstract The paraelectric ⇌ antiferroelectric phase transition of the compound Bi 2 Ti 4 O 11 is studied in situ by electron diffraction and electron microscopy. The transition is reversible and clearly second order. Above T c faint streaking at the superlattice positions persists. In the low-temperature phase, antiphase boundaries with a displacement vector R = 1/2[101] are revealed; they show a finite width, suggesting a gradual displacement of the Bi atoms at the transition. A model for the domain wall configuration is proposed, based on the influence of the lone pairs of Bi 3+ ions at the transition.
