Engraulídeos brasileiros do gênero Anchoviella

Nos anos de 1948-49, o autor teve ocasião de estudar os representantes da família Engraulidae que frequentam a costa brasileira, pesquisa essa supervisionada gentilmente pelo Dr. Samuel F. Hildebrand, ictiólogo do U. S. Fish & Wildlife Service, de Washington. Dessa investigação resultou a conveniência de se identificar e redescrever as espécies que fazem parte das coleções do Instituto Paulista de Oceanografia. O presente trabalho é, pois, baseado na revisão das manjubas americanas publicada pelo Dr. Hildebrand em 1943 e no trabalho em que figurou como co-autor: "Notes on some Brazilian anchovies (Family Engraulidae) with description of four new species" (1948). Graças à gentileza do Dr. Hildebrand, foi examinada uma coleção extensa do Museu Nacional dos Estados Unidos. De inestimável valor foi a manipulação de exemplares constantes da coleção do Dr. W. C. Schroeder, do Museu de Zoologia Comparada, especialmente rica em exemplares do Brasil. O autor muito deve ao Dr. Hildebrand pelo trabalho enorme desenvolvido nesse sentido. No texto, obedeceu-se a seqüência sempre uniforme quanto aos caractéres peculiares a cada espécie, de modo a facilitar o estudo, por parte de outras pessoas interessadas no grupo. A distribuição geográfica dos espécimes aqui considerados figura no Mapa n.º 1.

Engraulídeos brasileiros, do gênero Anchoa

Neste trabalho, o autor estuda os Engraulídeos do gênero Anchoa ocorrentes no Brasil. Depois de se referir a questões de ordem nomenclatural, chama a atenção para o fato de existirem divergências quanto à caracterização de espécies pertencentes a diversos gêneros, como, por exemplo, Anchoa e Anchoviella. Tendo examinado grande número de exemplares encaminhados, para estudo, ao Instituto Paulista de Oceanografia, o autor, baseado em estudos feitos, em 1948, sob a direção do falecido Dr. SAMUEL F. HILDEBRAND, ictiologista do U. S. Fish & Wildlife Service, de Washington, organizou uma chave para identificação das espécies de Anchoa ocorrentes em águas brasileiras. Após ter discutido a significação do termo "manjuba", demonstra o autor a importância econômica desses peixes, sobretudo no E. de S. Paulo onde grandes quantidades de Anchoa nasuta Hildebrand & Carvalho, de Engtaulis anchoita Hubbs & Marini e de Anchoa januaria (Steindachner) são utilizadas na indústria. Condena, aliás, o autor a maneira pouco lógica pela qual vem o produto sendo trabalhado, acrescentando que a mesma está longe de corresponder ao que dela se espera. Apresentando alguns dados biológicos sobre Anchoa januaria A. hepsetus hepsetus e A. tricolor, o autor dá os caracteres de 10 espécimes frequentadores do litoral brasileiro, com os desenhos correspondentes a cada uma delas, figurando em duas estampas.

Anchoviella hildebrandi n. sp. Engraulídeo do rio Paraguaçú: Bahia

Trata o presente trabalho da descrição de Anchoviella hildebrandi n. sp., Engraulídeo da região de Caxoeira, rio Paraguaçú, na Bahia. A espécie é muito próxima de Anchoviella brasiliensis HILDEBRAND, do rio Ribeira de Iguapé (E. de S. Paulo) e de Anchoviella jamesi (JORDAN & SEALE) , do rio Jutai e lago Aleixo (E. do Amazonas). O autor apresenta a diagnose da nova especie, confrontando os caracteres que Ihe sao peculiares com os das duas especies ácima citadas. A denominacáo dada á nova especie constitue modesta homenagem á memoria do Dr. SAMUE L F. HILDEBRAND, ictiólogo do U. S. Fish & Wildlife Service, de Washington.

Clinical and epidemiological study of 27 poisonings caused by ingesting puffer fish (Tetrodontidae) in the states of Santa Catarina and Bahia, Brazil

Puffer fish can be poisonous due to the presence of the potent neurotoxins such as Tetrodotoxin (TTX) and Saxitoxin (STX) found in its tissues. The authors report 27 human poisonings from ingestion of puffer fish in patients treated at Toxicology Centers in the states of Santa Catarina and Bahia, Brazil, between 1984 and January 2009. Poisonings were classified as moderate (52%) and severe (33%), two deaths were observed. Early diagnosis is very important to ensure respiratory support.

Parasite-host relationship between the tambaqui (Colossoma macropomum Cuvier 1818) and ectoparasites, collected from fish farms in the city of Rolim de Moura, State of Rondônia, Western Amazon, Brazil

In this study we investigated the relationship between tambaqui fish (Colossoma macropomumi Cuvier 1818) and parasites in two fish farms (L204S and L180N) in the state of Rondônia, Brazil, during a 1-year period. The objective of the study was to describe the relationships between parasites, hosts and the environment. From the 80 fish specimens collected, 100% were parasitized by at least one parasite species. Seven ectoparasites species were recorded, six of the class Monogenea: Anacanthorus spathulatusi, Mymarothecium spp. (Mymarothecium sp. 1, Mymarothecium sp. 2 and M. viatorum), Notozothecium sp. and Linguadactyloides brinkimanni, classified as dominants, and the copepod Perulernaea gamitanae, classified as subordinate. Despite their high prevalence, the parasites were not abundant. A. spathulatus presented positive and significant correlations between the abundance of parasitism and the standard length of the hosts in the two fish farms; Mymarothecium spp. showed significant correlations, negative in L180N, and positive in L204S; significant positive correlations were observed for Notozothecium sp. in L204S, and for L.brinkimanni in L180N. Young monogeneans were found; these parasites presented a negative correlation in L180N and a significant negative correlation in L204S. The results of the correlation between the relative condition factor (Kn) and the abundance of parasites were not significant for the recorded parasite species. Regarding the hepatosomatic relation (HSR) of fish and the abundance of parasites, Anacanthorus spathulatusi showed a significant negative correlation with the HSR in L180N, and a positive correlation in L204S. Mymarothecium spp. and Notozothecium sp. presented significant positive correlations in L204S. Considering the correlation of the fish splenosomatic relation (SSR) and the abundance of parasites, L. brinkimanni presented significant correlations, positive in L180N and negative in L204S. Despite 100% prevalence, the high water quality contributes to infracommunities with low parasite abundance and good levels of Kn, HSR and SSR, allowing good tambaqui development.

Rhipidocotyle gibsoni n. sp. from a Brazilian Freshwater Fish and Rhipidocotyle froesi n.sp. for r. baculum (linton, 1905) of Eckmann (1932) (Bucephalidae; Digenea)

Rhipidocotyle gibsoni n.sp. is described from Acestrorhynchus lacustris from Paraná River, brazil. It is most closely related to r. froesi n. sp. and to R. eckmanni in the shape of the cephalic hood, differing in the extent of the uterus, in the position of the vitelline follicles and in that the host is a freshwater fish. Rhipidocotyle froesi n. sp. is proposed for the marine specimens described by Eckmann (1932) as R. baculum (Linton, 1905).

Teaching-service integration: implications and roles in experiences of Undergraduate Courses in Nursing

The study aimed at understanding the implications of the teaching-service integration to nursing education from the perspective of teachers, students and professionals in Primary Healthcare as well as identifying the roles of teachers and professionals who follow practical experiences in education. This is a case study of qualitative approach carried out in five undergraduate courses in Nursing in the state of Santa Catarina. A total of 22 teachers and 14 professionals were interviewed and five focus groups were conducted with students. Results are presented in two categories: Implications of the teaching-service integration to education in Nursing: contributing factors and intervening factors and Relationships established in the experiences: a unison speech and a dissonant practice. The contributions of the teaching-service integration are undeniable. Despite this belief, there are intervening factors that need to be on the agenda for discussion. The role of facilitator in education emerged strongly despite conflicting perceptions remain.

Comparison of I-FISH and G-banding for the detection of chromosomal abnormalities during the evolution of myelodysplastic syndrome

Myelodysplastic syndrome (MDS) patients with a normal karyotype constitute a heterogeneous group from a biological standpoint and their outcome is often unpredictable. Interphase fluorescence in situ hybridization (I-FISH) studies could increase the rate of detection of abnormalities, but previous reports in the literature have been contradictory. We performed I-FISH and conventional karyotyping (G-banding) on 50 MDS patients at diagnosis, after 6 and 12 months or at any time if a transformation to acute myeloid leukemia (AML) was detected. Applying a probe-panel targeting the centromere of chromosomes 7 and 8, 5q31, 5p15.2 and 7q31, we observed one case with 5q deletion not identified by G-banding. I-FISH at 6 and 12 months confirmed the karyotype results. Eight cases transformed to AML during follow-up, but no hidden clone was detected by I-FISH in any of them. The inclusion of I-FISH during follow-up of MDS resulted in a small improvement in abnormality detection when compared with conventional G-banding.

Evaluation of chromosomal abnormalities by cIg-FISH and association with proliferative and apoptotic indexes in multiple myeloma

Eighty-six newly diagnosed multiple myeloma (MM) patients from a public hospital of São Paulo (Brazil) were evaluated by cIg-FISH for the presence of del(13)(q14), t(4;14)(p16.3;q32) and del(17)(p13). These abnormalities were observed in 46.5, 9.3, and 7.0% of the patients, respectively. In order to identify the possible role of del(13)(q14) in the physiopathology of MM, we investigated the association between this abnormality and the proliferative and apoptotic indexes of plasma cells. When cases demonstrating t(4;14)(p16.3;q32) and del(17)(p13) were excluded from the analysis, we observed a trend towards a positive correlation between the proportion of cells carrying del(13)(q14) and plasma cell proliferation, determined by Ki-67 expression (r = 0.23, P = 0.06). On the other hand, no correlation between the proportion of cells carrying del(13)(q14) and apoptosis, determined by annexin-V staining, was detected (r = 0.05, P = 0.69). In general, patients carrying del(13)(q14) did not have lower survival than patients without del(13)(q14) (P = 0.15), but patients with more than 80% of cells carrying del(13)(q14) showed a lower overall survival (P = 0.033). These results suggest that, when del(13)(q14) is observed in a high proportion of malignant cells, it may have a role in determining MM prognosis. Another finding was a statistically significant lower overall survival of patients with t(4;14)(p16.3;q32) (P = 0.026). In the present study, almost half the patients with t(4;14)(p16.3;q32) died just after diagnosis, before starting treatment. This fact suggests that, in São Paulo, there may be even more patients with this chromosomal abnormality, but they probably die before being diagnosed due to unfavorable socioeconomic conditions. This could explain the low prevalence of this chromosomal abnormality observed in the present study.

Relationship between the price of fish and its quality attributes: a study within a community at the University of São Paulo, Brazil

The aim of this study was to evaluate the associations between the products' market price and attributes related to fish purchase and consumption within a university community in Brazil. A structured questionnaire consisting of a five-point Likert scale was used. It was previously tested and made available to the university community via the Internet. The sample comprised 1966 voluntaries including university students and faculty and staff members. A descriptive analysis of data was performed using Spearman's correlation analysis. The results showed that the majority of the respondents (56%) consume fish at home; some consume fish at restaurants (39%), and 5% at family or friends' houses, reinforcing the idea that variables such as culture and reference groups are fundamental determinants of purchase and consumption behavior. It was identified a significant (p < 0.001) and very strong correlation between the attributes price and nutritional value (r = 0.92); price and availability at the usual places of purchase (r = 0.92); price and packaging (r = 0.92); price and brand name (r = 0.91); and price and of the Federal Inspection stamp (r = 0.91) and a low positive correlation (p < 0.001) between the price variable and the initiative for fish traceability (r = 0.16). This study demonstrated that the price of fish is associated with the quality of the product and the attributes related to it such as packaging, nutritional value, and availability of the product in the market.

Sensory acceptability and fatty acid profile of fish crackers made from Carassius gibelio

Abstract In this study, our aim was to consider the production of fish crackers using Carassius gibelio and to investigate the fatty acid profile and sensory quality of the fish crackers. Fish cracker mixture with a ratio 3.5:1.5 (minced fish/wheat starch) was obtained. Based on the total minced fish and starch level, 1.75% salt, 0.25% black pepper, 2% sunflower oil, 1% baking powder and 10% cold water (4 °C) were added and stirred until a homogenous mixture was obtained. The mixture was compressed in an extractor and baked. The moisture content of minced fish (CMF), cracker dough (CD) and crackers (CCr) was 77.73 ± 0.14%, 63.10 ± 2.18% and 7.95 ± 0.67% respectively. The n6/n3 ratio of crackers was 2.61 ± 0.20, PUFA/SFA ratio 2.28 ± 0.06 and DHA/EPA ratio 1.81 ± 0.01. The overall acceptability score obtained by the sensory evaluation of panelists was very high (8.09 ± 0.25).
