ABSTRACT

This study aimed to describe and validate the formation of the rings in the spine of the pectoral fin and to determine the coherence of the OTC mark with the rings of three species of Caspian Sea sturgeon, the Persian sturgeon (Acipenser persicus), the Starry sturgeon (Acipenser stellatus) and Ship sturgeon (Acipenser nudiventris). Validation was achieved by comparing the total radius of the fin spine of fish of known age after one and two years of growth with the measured radius of the first and second rings in the zone. There was no overlap between the measured radius for the first year and the increase for the second. The Ship sturgeon showed the largest width of the second ring followed by the Persian sturgeon and Stellate sturgeon. The results indicate that the highest growth parameter belongs to the juvenile Ship sturgeon. This research showed that chemically marking the fin spines of juvenile Acipenseridae leads to unbiased estimates and contributes to the knowledge of the population dynamics of these species. The study found that the combination of the dial ring of the pectoral fin spine with growth validated the age estimation in juvenile sturgeon Ship, Persian, and Starry sturgeon.(AU)


O objetivo deste estudo foi descrever e validar a formação dos anéis na espinha da nadadeira peitoral de três espécies de esturjão do mar Cáspio: o esturjão-persa (Acipenser persicus), o esturjão-estrelado (Acipenser stellatus) e o esturjão-de-navio (Acipenser nudiventris), bem como determinar a coerência da marca OTC com os anéis dessas três espécies. A validação foi alcançada comparando-se o raio total da espinha da nadadeira de peixes de idade conhecida, após um e dois anos de crescimento, com o raio medido do primeiro e segundo anéis na zona. Não houve sobreposição entre o raio medido no primeiro ano e o aumento no segundo. O esturjão-de-navio mostrou a maior largura do segundo anel, seguido pelo esturjão-persa e pelo esturjão-estrelado. Os resultados indicam que o maior parâmetro de crescimento pertence ao esturjão-de-navio juvenil. Esta pesquisa mostrou que a marcação química dos espinhos das nadadeiras de juvenis de Acipenseridae leva a estimativas imparciais e contribui para o conhecimento da dinâmica populacional dessas espécies. O estudo descobriu que a combinação do anel do mostrador da barbatana peitoral espinhal com o crescimento validou a estimativa de idade em esturjão-de-navio juvenil, esturjão-persa e esturjão-estrelado.(AU)

ABSTRACT

OBJECTIVES: to assess how nurses perceive autonomy, control over the environment, the professional relationship between nurses and physicians and the organizational support and correlate them with burnout, satisfaction at work, quality of work and the intention to quit work in primary healthcare. METHOD: cross-sectional and correlation study, using a sample of 198 nurses. The tools used were the Nursing Work Index Revised, Maslach Burnout Inventory and a form to characterize the nurses. To analyze the data, descriptive statistics were applied and Spearman's correlation coefficient was used. RESULTS: the nurses assessed that the environment is partially favorable for: autonomy, professional relationship and organizational support and that the control over this environment is limited. Significant correlations were evidenced between the Nursing Work Index Revised, Maslach Burnout Inventory and the variables: satisfaction at work, quality of care and the intent to quit the job. CONCLUSION: the nurses' perceptions regarding the environment of practice are correlated with burnout, satisfaction at work, quality of care and the intent to quit the job. This study provides support for the restructuring of work processes in the primary health care environment and for communication among the health service management, human resources and occupational health areas. .


OBJETIVOS: avaliar percepções dos enfermeiros sobre autonomia, controle sobre o ambiente, relação profissional entre enfermeiro e médico e suporte organizacional e correlacioná-las com Burnout, satisfação no trabalho, qualidade do cuidado e intenção de deixar o trabalho, na atenção básica. MÉTODO: estudo transversal e correlacional, com amostra de 198 enfermeiros. Foram utilizados o Nursing Work Index Revised, o Inventário de Burnout de Maslach e uma ficha de caracterização do enfermeiro. Para análise dos dados, foi realizada estatística descritiva e utilizado o coeficiente de correlação de Spearman. RESULTADOS: os enfermeiros avaliaram que o ambiente é parcialmente favorável para: autonomia, relação profissional e suporte organizacional e que há pouco controle sobre o mesmo. Evidenciaram-se correlações significativas entre o Nursing Work Index Revised, o Inventário de Burnout de Maslach e as variáveis: satisfação no trabalho, qualidade de cuidado e intenção de deixar o trabalho. CONCLUSÃO: percepções dos enfermeiros acerca do ambiente da prática correlacionam-se com Burnout, satisfação no trabalho, qualidade do cuidado e intenção de deixar o trabalho. Este estudo fornece subsídios para reestruturação de processos de trabalho no ambiente da atenção básica e para comunicação entre as áreas de gestão de serviços de saúde, recursos humanos e saúde do trabalhador. .

ABSTRACT

Tetracyclines [TCs] are broad-spectrum antibiotics that are used widely in veterinary medicine. The present study was carried out to trace the residues of oxytetracycline [OTC] and tetracycline [TC] in pasteurized milk that is marketed in Tehran with the use of a High Performance Liquid Chromatography [HPLC]. Ninety milk samples were collected during five sequential days from the products of six major dairy companies. OTC and TC residues were extracted and quantified by an HPLC method with an ultraviolet radiation detector. TC residues were found in seven [7.8%] milk samples. The OTC and TC in almost all samples were lower than 100 ppb [parts per billion], which is the maximum residue level advised. However, the total residue of OTC and TC in one milk sample was 138.8 ppb. In conclusion, due to the presence of a significant amount of TC residues in a number of milk samples, more studies and further supervision of the quality of milk products are required

ABSTRACT

The concentration of Terramycin and Furazolidone residues in broiler meat following their subtherapeutic use in the ration of the birds were detected as 296 ng/g, 174 ng/g, 40 ng/g, 60 ng/g and 124 ng/ml in kidney, liver, thigh muscle, breast muscle and serum for Terramycin and 270 ng/g 160 ng/g and 88 ng/ml in kidney, liver and serum for Furazolidone. One week of withdrawal period from the antibiotic in feed/water was sufficient to render the meat free from residues.

ABSTRACT

La presencia de antibacterianos y antiparasitarios residuales fue investigada en muestras de carne de peces silvestres de consumo humano pescados alrededor de un recinto de acuicultura en Cochamó (41° 29' S; 72° 19'W), X Región, Chile. Esta investigación demostró que peces silvestres, incluyendo róbalo (Elginops maclovinus), cabrilla (Sebastes capensis) y truchas de vida libre (Oncorhynchus mykiss), ingieren alimento artificial para salmón y que la carne de algunos ejemplares de estos peces contienen tetracicilina y quinolona en cantidades detectables. Estos resultados sugieren que el uso de antibacterianos en la acuicultura del salmón, como ha sido demostrado en otros países, tiene efectos ambientales que se proyectan más allá de los recintos de acuicultura. Se indica que dada la relevancia de estos hallazgos para la salud humana y animal, el ambiente requerirá de estudios más amplios y detallados para implementar futuras regulaciones del uso de antibacterianos en acuicultura.


The presence of residues of tetracycline, quinolones and antiparasitic drugs was investigated in wild fish captured around salmon aquaculture pens in Cochamó, Region X, Chile. Residues of both antibiotics were found in the meta of two species of wild fish that are consumed by humans, robalo (Elginops maclovinus) and cabrilla (Sebastes capensis) . These findings suggest that the antibiotic usage in salmon aquaculture in Chile has environmental implications that may affect human and animal health. More studies are needed in Chile to determine the relevance of these findings for human and animal health and the environment to regulate this use of antibiotics.
