Toward reference intervals for shellfish: An illustrative case of feeding and respiratory activities in the Pacific cupped oyster,   Crassostrea gigas
Provedor de dados: 5
Autores: François, Cyrille; Haure, Joel; Billy, Jean-christophe; Renault, Tristan.
Background The Quality Assurance and Laboratory Standards Committee of the American Society for Veterinary Clinical Pathology and the guidelines of the Clinical and Laboratory Standards Institute provide a framework for establishing reference intervals of physiological parameters in reputedly healthy individuals, humans, and terrestrial animals, respectively. This framework was applied for the first time to the Pacific cupped oyster, Crassostrea gigas. Reference intervals (RIs) would, first, be of interest for research purposes, including pathophysiology studies. RI determination is the first step before considering the use of RIs for field applications by farmers and marine shellfish health services. Objectives The purpose of this study was to propose...

Du concept de santé à la détermination d’intervalles de référence chez l’huître creuse Crassostrea gigas
Provedor de dados: 5
Autores: Francois, Cyrille.
Of interest of everyone, health is not an easy concept to figure out. Although there is no universal definition of health, its various uses and meanings allow us to specify its biological, psychic and social dimensions. In animal health, the biological dimension remains the most studied, there is therefore no consensual definition of international animal health. So how to understand the health of marine shellfish? A living being can be functionally described in physiopathology by monitoring biomarkers under laboratory conditions. In men and many animals, "normal" biomarker values have been proposed; these have been determined by carrying out measurements or observations in samples of healthy populations, the rigorous selection of these populations and...

The reference intervals for leukocytes and lymphocytes currently used by most clinical laboratories present limitations as they are primarily derived from individuals of North American and European origin. The objective this study was to determine reference values for peripheral blood B lymphocytes, T lymphocyte subsets (CD4+, CD8+, naïve, memory, regulatory, TCRαβ and TCRγδ+) and NK cells from blood donors in Salvador-Bahia, Brazil. Results: The proportion of included male subjects was 73.7% and the median ages of males (34) and females (35) were found to be similar. Absolute counts total lymphocytes subsets to both gender was 1,956 (1,060-4,186) cells and relative values 34%. The T CD4+ and T CD8+ lymphocytes relative values was 51% (20-62) and 24%...

Reference range for T lymphocytes populations in blood donors from two different regions in Brazil

Autores: Torres,A.J.L.; Angelo,A.L.D.; Netto,E.M.; Sampaio,G.P.; Souza,D.F.C.; Inocêncio,L.A.; Lemos,J.A.R.; Brites,C.
This study defined the normal variation range for different subsets of T-lymphocyte cells count in two different Brazilian regions. We analysed the T-lymphocytes subpopulations (CD3+, CD4+, CD8+) in blood donors of two Brazilian cities, located in North (Belem, capital state of Para, indian background) and Northeast (Salvador, capital state od Bahia, African background) regions of Brazil. Results were compared according to gender, stress level (sleep time lower than 8 hours/day), smoking, and alcohol intake. Lymphocytes subpopulations were measured by flow cytometry. Five hundred twenty-six blood donors from two Brazilians cities participated in the study: 450 samples from Bahia and 76 samples from Pará. Most (60%) were men, 59% reported alcohol intake,...

Provedor de dados: 56
Autores: Rufino,R.; Costa,C.H.; Lopes,A.J.; Maiworm,A.I.; Maynard,K.; Silva,L.M.R.A.; Dias,R.M.
The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak of expiratory flow (PEF), forced expiratory flow at 50% (FEF50%), 75% average vital capacity (FEF25-75%), and average forced expiratory flow time (FEFT). This was a prospective study using results from chest radiographs, electrocardiograms, and questionnaires to investigate the participants' respiratory symptoms, sedentarism, and comorbidities (Charlson comorbidity index). From December 2010 to July 2014, individuals were randomly selected from various locations in the state of Rio de Janeiro. All individuals were...

Spot urine porphyrins/creatinine ratio profile of healthy Brazilian individuals adjusted for personal habits
Provedor de dados: 56
Autores: Alves,A.N.L.; Sumita,N.M.; Burattini,M.N.; Della Rosa,H.V.
Changes in urinary porphyrin excretion may be the result of hereditary causes and/or from environmental or occupational exposure. The objective of this study was to measure the amount of some porphyrins in spot urine samples obtained from volunteers randomly selected from a healthy adult population of São Paulo with a sensitive HPLC method and to estimate normal ranges for a non-exposed population. Spot urine samples were collected from 126 subjects (both genders, 18 to 65 years old) not occupationally exposed to porphyrinogenic agents. Porphyrin fractions were separated on RP-18 HPLC column eluted with a methanol/ammonium acetate buffer gradient, pH 4.0, and measured fluorometrically (excitation 405 nm/emission 620 nm). The amount of porphyrins was...
