High dietary inclusion level of fresh herring impairs growth of rainbow trout, Oncorhynchus mykiss

1998

Abstract One-year old rainbow trout (initially 350–670 g) were fed for 15 weeks diets containing various amounts of water (23–67%). This was achieved by replacing fish meal with Baltic herring. The growth of rainbow trout, whether measured as wet weight, protein or energy, was impaired when 50–55% dietary water was fed. The fish compensated for increasing dietary water content by consuming more diet so that the dry matter intake of the diets with 23 and 67% water were equal. Partitioning of growth into protein and lipid as well as protein and energy retention efficiencies were unaffected by dietary water. It is suggested that there is a metabolic cost of consuming more food when compensatin…

Effect of different salting technologies on the chemical and microbiological characteristics of PDO Pecorino Siciliano cheese

2011

The present work was carried out to evaluate the effect of two salting technologies [dry salting (DS) and the combined dry-brine salting (DBS)] on the chemicophysical and microbiological characteristics of PDO Pecorino Siciliano cheeses of different final weight (6 and 12 kg). Dry matter was significantly influenced by both salting process and final size. Twelve kilogram cheeses treated by DBS showed higher protein content with higher soluble nitrogen per cent than 6 kg cheeses. Salt content was in the range 3.1–4.0% on dry matter. The colour did not show significant differences for any of the factors, but 12 kg cheeses subjected to DS showed higher yellow index than the other cheeses. The …

Impact of Manaus City on the Amazon Green Ocean atmosphere: Ozone production, precursor sensitivity and aerosol load

2010

As a contribution to the Large-Scale Biosphere-Atmosphere Experiment in Amazonia – Cooperative LBA Airborne Regional Experiment (LBA-CLAIRE-2001) field campaign in the heart of the Amazon Basin, we analyzed the temporal and spatial dynamics of the urban plume of Manaus City during the wet-to-dry season transition period in July 2001. During the flights, we performed vertical stacks of crosswind transects in the urban outflow downwind of Manaus City, measuring a comprehensive set of trace constituents including O3, NO, NO2, CO, VOC, CO2, and H2O. Aerosol loads were characterized by concentrations of total aerosol number (CN) and cloud condensation nuclei (CCN), and by light scattering proper…

Biopolymer-Based Hybrid Hydrogels for Biomedical Applications: From Macroscopic to Nanosized Systems

2021

Les partícules portadores basades en biopolímers són biocompatibles i ofereixen la capacitat d’incorporar agents actius hidròfils i hidròfobs. La incorporació d’un fàrmac en una matriu polimèrica pot millorar-ne la protecció contra la degradació en mitjans fisiològics severs. A més, pot controlar-ne l’alliberament al lloc d’acció específic, amb una biodisponibilitat terapèutica augmentada i efectes secundaris o toxicitat minimitzats. Aquesta tesi presenta la preparació de diferents sistemes híbrids de polisacàrids per a encapsular substàncies hidròfiles, que posteriorment són alliberades. Es preparen portadors que varien de mida macroscòpica a nanomètrica mitjançant diferents mètodes: gelif…

Tear <sup>1</sup>H Nuclear Magnetic Resonance-Based Metabolomics Application to the Molecular Diagnosis of Aqueous Tear Deficiency and Me…

2020

<b><i>Purpose:</i></b> Meibomian gland dysfunction (MGD) is a major cause of signs and symptoms related to dry eyes (DE) and eyelid inflammation. We investigated the composition of human tears by metabolomic approaches in patients with aqueous tear deficiency and MGD. <b><i>Methods:</i></b> Participants in this prospective, case-control pilot study were split into patients with aqueous tear deficiency and MGD (DE-MGD [<i>n</i> = 15]) and healthy controls (CG; <i>n</i> = 20). Personal interviews, ocular surface disease index (OSDI), and ophthalmic examinations were performed. Reflex tears collected by capillarity were pr…

Influence of Innovative Processing on γ-Aminobutyric Acid (GABA) Contents in Plant Food Materials

2017

Over the last several decades, γ-aminobutyric acid (GABA) has attracted much attention due to its diverse physiological implications in plants, animals, and microorganisms. GABA naturally occurs in plant materials and its concentrations may vary considerably, from traces up to μmol/g (dry basis) depending on plant matrix, germination stage, and processing conditions, among other factors. However, due to its important biological activities, considerable interest has been shown by both food and pharmaceutical industries to improve its concentration in plants. Natural and conventional treatments such as mechanical and cold stimulation, anoxia, germination, enzyme treatment, adding exogenous gl…

Effects of feeding frequency on growth and food utilisation of rainbow trout (Oncorhynchus mykiss) fed low-fat herring or dry pellets

1998

Abstract One-year-old rainbow trout (weight range 400–700 g) were fed for 18 weeks on low-fat herring or commercial dry pellets 1, 2 or 4 times in a day. Quadratic regression analysis indicated that at least three feedings were required for maximum growth and that fish fed a dry diet could benefit from even more frequent feeding. The proportion of lipid in growth increased with increased number of feedings, but the protein content was not affected (mean 18.6% protein wet basis). Food consumption (dry weight) was affected in a similar manner for both diets and its maximum occurred at slightly higher frequency than for maximum growth. No effects of feeding frequency or type of diet on energy …

Influence of Polymer Molecular Weight on Drug–polymer Solubility: A Comparison between Experimentally Determined Solubility in PVP and Prediction Der…

2015

ABSTRACT: In this study, the influence of polymer molecular weight on drug–polymer solubility was investigated using binary systems containing indomethacin (IMC) and polyvinylpyrrolidone (PVP) of different molecular weights. The experimental solubility in PVP, measured using a differential scanning calorimetry annealing method, was compared with the solubility calculated from the solubility of the drug in the liquid analogue N-vinylpyrrolidone (NVP). The experimental solubility of IMC in the low-molecular-weight PVP K12 was not significantly different from that in the higher molecular weight PVPs (K25, K30, and K90). The calculated solubilities derived from the solubility in NVP (0.31–0.32 …
