Microflora associated with healthy and diseased turbot (Scophthalmus maximus) from three farms in northwest Spain

14 páginas, 4 tablas, 3 figurasA comparative analysis of the microbiological quality of three turbot (Scophthabnus maximus) farms (A, B, and C) located in Galicia (northwest Spain) is given. The microbial load and types of bacteria in the internal organs (liver and kidney) of apparently healthy fish was monitored over a year, and all the disease problems occurring during this survey were analyzed. The percentage of healthy turbot in which positive bacterial growth was obtained was relatively high in the three ongrowing facilities. Farm A exhibited the poorest conditions of fish health with an average of 42% fish infected, while farm B showed the best microbiological quality with 27% of turbot harbouring bacteria in the internal organs. In all three farms, a wide range of bacteria was found in healthy turbot with Vibrio ( V. splendidus-V pelagius, Vjisheri-V harveyi and Vibrio spp.) and Pseudomonas spp. being the predominant groups comprising at least 80% of the total bacterial isolates in each farm. The highest number of pathological problems (22 ) with the most diverse bacterial flora occurred in farm A. Vibrio spp. and Pseudomonas spp. were the most prevalent bacteria recovered from diseased turbot. Haemorrhages in palate and jaws, tail and fins, and ulcerative lesions were the most frequent external clinical signs of diseased fish recorded in the three farms. However, it was not possible to associate a particular bacterial species with a specific pathology. Routine use in farm A of oxolinic acid and nitrofurantoin may have led to the development in the Vibrio strains of resistances to both chemotherapeutants (up to 25%).This study was supported by Grants MAR 9 l- 1133~CO2-0 1 and MAR 89- 0270 from the Comision Interministerial de Ciencia y Tecnologia (CICYT), XUGA 8030389 from Xunta de Galicia (Spain), and EUREKA project No. EU-347, between Spain and Norway.Peer reviewe

Losing silence, gaining acceptance:A qualitative exploration of the role of thoughts in adult patients with subjective tinnitus

Objective: Tinnitus is one of the most common somatic symptoms to affect humanity. Prevalence rates in adult populations range from 8.2 to 20.1%. Our aim was to understand the beliefs and interpretations of tinnitus and the experience of living with it. Design: An in depth grounded theory interview study. Grounded theory is an inductive approach to developing theory. Sample: Thirteen contrasting people with tinnitus who had sought help from clinical services in England. Results: We identified that the thinking patterns that people held around their tinnitus impacted how they experienced it. A core category emerged from the data, “sense making”. Around “sense making” eight other themes operated. Results are discussed in relation to the literature on tinnitus acceptance and beliefs. Conclusions: The aim of interventions is to foster understanding and enhance perceptions of control, which may minimise the emotional impact of tinnitus and reduce the perceived severity of consequences

The effectiveness of a practical half-time re-warm-up strategy in youth female basketball players

Problem Statement: Passive rest during basketball games could reduce athletes’ performance and increase the risk of injury during the second half of the game due to loss of muscle temperature. Approach: The re-warm-up activities during half-time could help avoid this problem, but there is a lack of research on their efficacy, especially in basketball. Purpose: This study aimed to assess the influence of two half-time re-warm-up strategies (that do not demand additional equipment) on measures of performance and the physical, sports and perceptual response during a basketball simulated match. Methods: Ten female basketball players U16 completed a traditional intervention and alternative strategy based on bouncing, in which participants completed two 40-minute games (4 x 10-minute periods with a 10-minute half-time interspersing the third and fourth periods) separated by four days. The traditional trial comprised a passive 6-minute period followed by 3 minutes of shooting wheel, whilst the alternative trial comprised a passive 6-minute period, followed by 1 minute of bouncing and 2 minutes of shooting wheel. The re-warm-up protocols were completed 1 minute before the beginning of the second half. Results: The re-warm-up did not show significant effects on jump performance and rating of perceived exertion immediately after half-time and after the second half of the basketball simulated match. No significant changes were identified for heart rate and locomotory responses during the game, except for the distance covered at a very light speed which was significantly higher in the traditional group. Conclusions: These data support that adding a bouncing exercise to a classic re-warm-up during half-time does not lead to additional improvement in young female basketball players

Retinoblastoma incidence and sunlight exposure

To evaluate positive findings from an earlier report, we studied the relation between retinoblastoma incidence and ultraviolet (UV-B) radiation levels in the Surveillance, Epidemiology, and End Results (SEER) programme areas of the USA using weighted regression, as well as in international data after adjusting for race, economic development, and climate. The association was not statistically significant within the USA (P> 0.20). At an international level, the relation was significant overall and after adjusting for economic development, but it was not significant after adjusting for race and tropical climate, suggesting that environmental factors other than UV-B may be responsible for the geographic patterns of retinoblastoma. © 2000 Cancer Research Campaig

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector

A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13  TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139  fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV

Adipose tissue levels of organochlorine pesticides and polychlorinated biphenyls and risk of non-Hodgkin's lymphoma.

In this nested case-control study we examined the relationship between non-Hodgkin's lymphoma (NHL) and organochlorine pesticide exposure. We used a data set originally collected between 1969 and 1983 in the U.S. Environmental Protection Agency National Human Adipose Tissue Survey. Adipose samples were randomly collected from cadavers and surgical patients, and levels of organochlorine pesticide residues were determined. From the original study population, 175 NHL cases were identified and matched to 481 controls; 173 controls were selected from accident victims, and 308 from cases with a diagnosis of myocardial infarction. Cases and controls were mainly from cadavers (> 96%) and were matched on sex, age, region of residence within the United States, and race/ethnicity. Conditional logistic regression showed the organochlorine pesticide residue heptachlor epoxide to be significantly associated with NHL [compared with the lowest quartile: third quartile odds ratio (OR) = 1.82, 95% confidence interval (CI), 1.01-3.28; fourth quartile OR = 3.41, 95% CI, 1.89-6.16]. The highest quartile level of dieldrin was also associated with elevated NHL risk (OR = 2.70; 95% CI, 1.58-4.61), as were higher levels of oxychlordane, p,p'-DDE [p,p'-1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene], and ss-benzene hexachloride (ORs = 1.79, 1.99, and 2.47, respectively). The p-values for trends for these associations were significant. In models containing pairs of pesticides, only heptachlor epoxide and dieldrin remained significantly associated with risk of NHL. Limitations of this study include collection of samples after diagnosis and a lack of information on variables affecting organochlorine levels such as diet, occupation, and body mass index. Given the persistence of pesticides in the environment, these findings are still relevant today
