Diet-Induced Rabbit Models for the Study of Metabolic Syndrome

2019

Simple Summary In recent years, obesity and metabolic syndrome (MetS) have become more prevalent owing to increased unhealthy habits and sedentary lifestyles, becoming public health problems. Experimental studies have allowed us to explore the mechanisms underlying the pathophysiological processes related to MetS. Several research protocols can be carried out with minimal staff, maintenance, and resources in animals such as rabbits. High-fat diets enriched with other components, mainly cholesterol and sugars, result in the rapid development of hypercholesterolemia and vascular alterations as a response to dietary manipulation. Furthermore, other experimental models, including transgenic rab…

Histological and morphometric study of the components of the sinus and atrioventricular nodes in horses and dogs

2019

Abstract The cardiac nodes are the source of the electrical impulse that is transmitted to the heart, the aim of this work is study the histological and morphometric characteristics of the different components of the sinus and atrioventricular nodes in horses and dogs that help to know the physiopathology of these nodes. A group of ten horse hearts and five dog hearts were used. The region of the sinus and atrioventricular nodes was sectioned serially, and the block of tissue removed for study. The samples were assessed using a morphometric analysis with the Image-Pro Plus 7.1 software and the acquisition of the images using a Leica DMD108 optic microscope. The shape of the horse's sinus no…

Revision of the taxonomic status of <i>Synthesium elongatum</i> (Ozaki, 1935) (Brachycladiidae), an intestinal digenean of narrow-ridged …

2019

Synthesium elongatum (Brachycladiidae) is an intestinal digenean described from the finless porpoise (Neophocaena asiaeorientalis) in Japan. Few records of this species exist and there is a remarkable morphological similarity between S. elongatum and S. tursionis, such that a synonymy between the species has been suggested previously. However, no morphological and/or molecular analysis has been carried out to clarify the taxonomic status of S. elongatum. In this study, we collected specimens of Synthesium sp. from N. asiaeorientalis in western Japan. The specimens possess lobed testes within the third quarter of the body, a round ovary, and vitellaria extending to level of uterine field, wh…

Animal Welfare Attitudes (AWA) are defined as human attitudes towards the welfare of animals in different dimensions and settings. Demographic factors, such as age and gender are associated with AWA. The aim of this study was to assess gender differences among university students in a large convenience sample from twenty-two nations in AWA. A total of 7914 people participated in the study (5155 women, 2711 men, 48 diverse). Participants completed a questionnaire that collected demographic data, typical diet and responses to the Composite Respect for Animals Scale Short version (CRAS-S). In addition, we used a measure of gender empowerment from the Human Development Report. The largest varia…

Problématiques de la nutrition en ophtalmologie – application à la dégénérescence maculaire liée à l’âge

2014

Nutrition in ophthalmology – clinical application to age-related macular degeneration «Let food be your medicine.» This contribution from Hippocrates is still timely addressed, especially in the field of ophthalmology. Observational epidemiology reports close associations between food habits and the risk or prevention of several ocular pathologies such as cataract or Age-related Macular Degeneration (AMD). Anti-oxidant vitamins, minerals and lipids are the nutrients that have been the most widely studied. Interventional epidemiology and experimental works partially corroborated these findings. Unexpectedly, the benefit of long chain omega 3 polyunsaturated fatty acids in the prevention of l…

Partial substitution of fish meal with vegetable protein sources in a diet for sea bass: effects on lipogenesis

2005

Three isoproteic (49.4%) and isolipidic (17.0%) diets were prepared: A control diet FM, in which protein was derived from fish meal and two experimental diets in which 70% of the fish meal protein was substituted with wheat gluten meal (WGM) or wheat gluten meal plus soybean meal (WGMsb), respectively. The essential limiting amino acids were added to satisfy the requirements of the species (Tibaldi et al., 1996). Three hundred and fifteen sea bass (initial weight = 23.9±0. 1g )were randomly divided into nine homogenous groups. The animals were reared in a closed recirculation system at 23.9 ◦ C and were fed ad libitum twice a day for 96 days. The fish were weighed at the beginning and the e…

Environmental drivers of breeding sites in blackfly species of medical and veterinary importance in eastern Spain

2021

Geographical distribution and abundance of the pupae of six blackfly species of medical and veterinary concern were studied in eastern Spain according to three different sets of explanatory variables including in-stream variables, both (i) abiotic (i.e., physicochemical) and (ii) biotic (i.e., richness and abundance of either taxonomically or ecologically close related taxa), as well as (iii) meteorological and landscape variables. The results showed specific habitat requirements for pupation in Simulium (Boophthora) erythrocephalum (De Geer, 1776) and Simulium (Wilhelmia) equinum (Linnaeus, 1758), two of the six species studied regarding elevation and temperature. While the rest of the spe…

Two New Alternatives to the Conventional Arm-in-Cage Test for Assessing Topical Repellents

2021

Abstract European guidelines for testing attractant and repellent efficacy (i.e., Product type 19 [PT19]) have been in revision since 2017. A key topic of discussion is the current approach to evaluating topical repellents. The European Chemical Agency has stated field testing should be avoided because of mosquito-borne disease risks. However, the most common laboratory method, the arm-in-cage (AIC) test, may limit the reliable extrapolation of lab results to field conditions. This study’s main goal was to assess alternative laboratory methods for evaluating topical mosquito repellents that use mosquito landing rates more representative of those in the field. The study took place at three E…

Sociodemographic and psychological correlates of COVID-19 vaccine hesitancy and resistance in the young adult population in Italy.

2021

Background: Previous research has shown that young adults are more hesitant/resistant to COVID-19 vaccine uptake than older age groups, although the factors underlying this tendency are still under debate. The current study aimed to identify the sociodemographic and psychological correlates of vaccine hesitancy and resistance among young adults (18–40 years) during the nationwide COVID-19 vaccination campaign in Italy, the first country after China being hit by the pandemic and which suffered a large number of fatalities. Methods: This is a cross-sectional, web-based study conducted in Italy using an ISO-certified international survey company (respondi.com). Data were collected on 1200 part…

Safety and immunogenicity of RIX4414 live attenuated human rotavirus vaccine in adults, toddlers and previously uninfected infants

2003

Abstract A live attenuated human rotavirus (HRV) vaccine, strain RIX4414, was tested sequentially in adults, previously infected toddlers, and previously uninfected infants. A single dose was given to adults and toddlers and found well tolerated. Next, a dose ranging (three different viral concentrations) safety and immunogenicity study was conducted in rotavirus IgA antibody negative infants (N=192), who received two doses of RIX4414 vaccine or placebo at 2 and 4 months of age. No side effects were seen after vaccination. Specifically, administration of RIX4414 vaccine was not temporally associated with fever, diarrhea, or increase in liver transaminases. Rotavirus IgA seroconversion range…
