Combination of Freezing, Low Sodium Brine and Cold Smoking on the Quality and Shelf-Life of Sea Bass (Dicentrarchus labrax L.) Fillets as a Strategy …
2021
Aquaculture is playing a leading role in both meeting the growing demand for seafood and increasing the sustainability of the fish production sector. Thus, innovative technologies that improve its sustainability, competitiveness, and safety are necessary for growth in the sector. This study aimed to develop cold smoked sea bass fillets from aquaculture. The aptitude of frozen and fresh fillets for cold smoking was investigated by processing both fresh and thawed fillets kept previously at &minus
Parasitic outbreak of the copepod Balaenophilus manatorum in neonate loggerhead sea turtles (Caretta caretta) from a head-starting program
2017
Abstract Background Diseases associated to external parasitosis are scarcely reported in sea turtles. During the last decades several organism have been documented as a part of normal epibiont community connected to sea turtles. The copepod Balaenophilus manatorum has been cited as a part of epibiont fauna with some concern about its parasitic capacity. This study serves three purposes, i.e. (i) it sheds light on the type of life style that B. manatorum has developed with its hosts, particularly turtles; (ii) it makes a cautionary note of the potential health risks associated with B. manatorum in sea turtles under captivity conditions and in the wild, and (iii) it provides data on effective…
Ovarian Transcriptomic Analysis Reveals Differential Expression Genes Associated with Cell Death Process after Selection for Ovulation Rate in Rabbits
2020
[EN] Transcriptomic analysis showed nineteen potential biomarkers in ovarian tissue from females belonged to a rabbit line selected for ovulation rate for 10 generations and the control line. These females differed not only in ovulation rate but also in prenatal survival since similar litter size were observed. Litter size is an essential trait in rabbit meat production but with low heritability. A selection experiment for ovulation rate has been performed for 10 generations to improve litter size in rabbits. The selected line increased two ova more than the control line but nevertheless a negative correlation was observed with prenatal survival. A transcriptomic study was performed, using …
Monitoring campaign over an edible dormouse population (Glis glis; rodentia: Gliridae) in Sicily: First report of mesocestodiasis
2021
Simple Summary In Nebrodi Park (Sicily, Italy), live many wild mammal species that move closer to human beings every day. The edible dormouse (Glis glis), in 2017 and 2018, was responsible for nut crop damage in the area. For this reason, a sanitary monitoring campaign involving 30 dormice was carried out by collecting rectal and conjunctival swabs and fur and nest content, which were then processed for laboratory examinations. A large presence of fleas belonging to Monopsyllus sciurorum was found. Necropsy of a dead dormouse revealed an infection of Mesocestoides lineatus, whose cysts were found in the abdomen cavity and on the liver; this is the first report of this in this species. Furth…
Prickly Pear By-Product in the Feeding of Livestock Ruminants: Preliminary Investigation
2020
Simple Summary The question of sustainability of animal nutrition has become a popular topic. The gains made by recycling safe, yet otherwise valueless, by-products and wastes from human food and fiber production (green feeds) may lessen the competition between humans and animals for crops and decrease the environmental impact of food production. In this context, prickly pear by-product, which results from Opuntia ficus-indica (L.) Mill. fruits processed for juice extraction, could be an optimum by-product to ruminant feeding. This study evaluates the nutritional characteristics and its stability during storage using potassium metabisulfite as a preservative agent. This preliminary investig…
Exercise Training Protocols in Rabbits Applied in Cardiovascular Research
2020
Simple Summary Several animal models have been used to understand the physiological adaptations produced by exercise training in the healthy and diseased cardiovascular system. Among those, the protocols for acute and chronic exercise in rabbits present several advantages compared to other large animal models. In addition, the rabbit model has important physiological similarities with humans. On the other hand, the design of the training protocol is a key factor to induce the physiological adaptations. Here, we review the different training protocols used in rabbits and the different physiological adaptations produced in the cardiovascular system, in normal and pathological conditions. Abst…
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…
The Inclusion of a Supercritical Fluid Extract, Obtained From Honey Bee Pollen, in the Diet of Gilthead Sea Bream (Sparus aurata), Improves Fish Immu…
2020
In the present study, the immune-stimulatory effect of two levels of honey bee pollen (5 and 10%, P5 and P10 treatment, respectively) and its supercritical fluid extract (0. 5 and 1%, E0.5 and E1, respectively) included in the diet, was tested in gilthead seabream (Sparus aurata). The in vivo trial was preceded by the evaluation of antioxidant properties of three different bee pollen extracts obtained by water, ethanol 80%, and Supercritic Fluids Extraction (SFE). The preliminary evaluation attested that the SFE showed the lowest extraction yield (10.47%) compared to ethanol 80% (48.61%) and water (45.99%). SFE extract showed good antioxidant properties with high polyphenol content (13.06 m…
Adaptations and Predispositions of Different Middle European Arthropod Taxa (Collembola, Araneae, Chilopoda, Diplopoda) to Flooding and Drought Condi…
2012
Simple Summary This review summarizes adaptations and predispositions of different arthropod taxa (springtails, web spiders, millipedes and centipedes) to flood and drought conditions. The main focus sis directed to arthropod species, which are living in Middle European floodplain forests and wetlands, because of the fast change of flood and drought conditions in these habitats. Furthermore the effects of the predicted regional climate change like increasing aperiodic summer flooding and decreasing winter and spring floods are also discussed. Abstract Floodplain forests and wetlands are amongst the most diverse and species rich habitats on earth. Arthropods are a key group for the high dive…
Comparison between rectal and body surface temperature in dogs by the calibrated infrared thermometer
2020
Highlights • Dogs poorly tolerate rectal temperature measurements with a contact thermometer. • Existing alternative approaches used uncalibrated infrared thermometers. • Gum and inguinal temperature are correlated moderately to rectal temperature. • Hyperthermia was detected with sensitivity and specificity up to 90.0% and 78.6%. • Future studies should include a calibrated thermometer and control external factors.
