Enriched rearing environment and wild genetic background can enhance survival and disease resistance of salmonid fishes during parasite epidemics

2015

Summary 1. The importance and volume of aquaculture is increasing world-wide. Rearing practices play a key role in determining growth rate, survival and disease resistance in aquaculture fishes. Recent evidence suggests that in comparison with a standard stimulus-poor rearing environment, an enriched or variable rearing environment has significant positive effects on several traits underlying growth and well-being of fish. However, the effect of enriched rearing on one of the most important threats for aquaculture development, occurrence of parasitic infections, remains unknown. 2. We used surveillance data of experimental salmonid populations of wild and hatchery origin under semi-natural …

We constructed a food-based diet quality score (DQS) and examined its association with obesity measures, eating styles and nutrient intakes. Participants were 3592 individuals (764 dizygotic [DZ] and 430 monozygotic [MZ] twin pairs) from the FinnTwin16 study. The DQS (0–12 points) was constructed from a short 14 item food frequency questionnaire. Anthropometric measures and eating styles were self-reported. Nutrient intakes were calculated from food diaries completed in a subsample of 249 individuals (45 same-sex DZ and 60 MZ twin pairs). Twins were analyzed both as individuals and as twin pairs. The DQS was inversely associated with body mass index (β = −0.12, per one-unit increase in DQS,…

The evolution of lactase persistence in Europe. A synthesis of archaeological and genetic evidence

2012

Lactase persistence, the ability to digest the milk sugar lactose in adulthood, is highly associated with a T allele situated 13,910 bp upstream from the actual lactase gene in Europeans. The frequency of this allele rose rapidly in Europe after transition from hunter–gatherer to agriculturalist lifestyles and the introduction of milkable domestic species from Anatolia some 8000 years ago. Here we first introduce the archaeological and historic background of early farming life in Europe, then summarize what is known of the physiological and genetic mechanisms of lactase persistence. Finally, we compile the evidence for a co-evolutionary process between dairying culture and lactase persisten…

Fitness in soil and rhizosphere of Pseudomonas fluorescens C7R12 compared with a C7R12 mutant affected in pyoverdine synthesis and uptake.

2000

International audience; Fluorescent pseudomonads have evolved an efficient strategy of iron uptake based on the synthesis of the siderophore pyoverdine and its relevant outer membrane receptor. The possible implication of pyoverdine synthesis and uptake on the ecological competence of a model strain (Pseudomonas fluorescens C7R12) in soil habitats was evaluated using a pyoverdine minus mutant (PL1) obtained by random insertion of the transposon Tn5. The Tn5 flanking DNA was amplified by inverse PCR and sequenced. The nucleotide sequence was found to show a high level of identity with pvsB, a pyoverdine synthetase. As expected, the mutant PL1 was significantly more susceptible to iron starva…

Children Witnessing Domestic and Family Violence: A Widespread Occurrence during the Coronavirus Disease 2019 (COVID-19) Pandemic

2021

Across the world, children and adolescents are exposed daily to toxic levels of violent behaviors, including domestic and family violence. Violence increasingly has permeated and profoundly affected the lives of children, who are the most vulnerable members of society.1 Pediatric societies in Europe and North America have raised great concern over the effect that abusive experiences will have on present and future generations.1, 2, 3, 4 The global spread of coronavirus disease 2019 (COVID-19) during the past year has dramatically worsened the situation, contributing to a further increase in violence and aggression within households. Reports of domestic abuse and family violence have increas…

O-142 COVID19-free endometrium: Undetectable viral RNA in endometrial biopsies from positive symptomatic SARS-CoV-2 women

2021

Abstract Study question Does SARS-CoV-2 infect the endometrial tissue in women with coronavirus disease 2019 (COVID-19)? Summary answer Symptomatic women with COVID-19 report no presence, in the short term, of viral RNA from SARS-CoV-2 in the endometrium. What is known already The recent emergence of COVID-19, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has not allowed yet to establish putative relations between this disorder and other existing pathologies. It is the case with fertility problems and the reproductive organs, including a possible endometrial disorder caused by the virus. Thus, an important step is to elucidate the viral presence in different hu…

The UK needs a sustainable strategy for COVID-19

2020

The UK is well into the second wave of COVID-19, with 60 051 lives lost to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection to date, according to provisional data from the Office for National Statistics. Official UK Government data show that cases have been rising exponentially since late August, 2020, with increases across all regions in England in recent weeks.As of Nov 4, 2020, the UK had 25 177 confirmed daily cases. These are almost certainly underestimates as between Oct 17 and Oct 23, 2020, England alone had 52 000 estimated daily cases.Estimates of the effective reproduction number in England vary between 1.1 and 1.6.Daily deaths have doubled every fortnight si…

Characterizing BCL-2 family protein domains in membranes:insertion, interaction and apoptotic modulation roles

2015

El objetivo de mi tesis doctoral es el estudio de los dominios transmembrana (TMD) de las proteínas de la familia Bcl-2. La principal función de esta familia de proteínas es la regulación del proceso apoptótico (1,2). Para Ello, se establece un balance de interacciones proteína-proteína entre los miembros pro- y antiapoptóticos de esta familia proteica (3,4). Nuestra hipótesis de trabajo postula que los fragmentos transmembrana de dichas proteínas pueden estar implicados no sólo en su localización subcelular sino también en el establecimiento de la red de interacciones entre proteínas Bcl-2 así como en el desarrollo de su función apoptótica.. Para corroborar esta hipótesis, hemos analizado …

European ADPKD Forum multidisciplinary position statement on autosomal dominant polycystic kidney disease care

2018

Autosomal dominant polycystic kidney disease (ADPKD) is a chronic, progressive condition characterized by the development and growth of cysts in the kidneys and other organs and by additional systemic manifestations. Individuals with ADPKD should have access to lifelong, multidisciplinary, specialist and patient-centred care involving: (i) a holistic and comprehensive assessment of the manifestations, complications, prognosis and impact of the disease (in physical, psychological and social terms) on the patient and their family; (ii) access to treatment to relieve symptoms, manage complications, preserve kidney function, lower the risk of cardiovascular disease and maintain quality of life;…
