Growth curve of Nile tilapia from different families of the AquaAmérica variety

Selection can affect growth, changing performance and asymptotic values. However, there is little information about the growth of families in fish breeding programs. The aim of this study was to evaluate the performance and growth of families of Nile tilapia AquaAmérica. Twenty AquaAmérica families cultivated in a net cage (13.5 m3) for 181 days were evaluated. The nonlinear Gompertz regression model was fitted to the data by the weighted least squares method, taking the inverse of the variance of weight in different families and at different ages as the weighting variable. The model was adjusted to describe the growth in weight and morphometric characteristics. Two families showed highest (P<0.05) weights at both 133 days (family AA10: 743.2 g; family AA16: 741.2 g) and 181 days (family AA10: 1,422.1 g; family AA16: 1,393.4 g) of the experiment. In both experimental periods, the males showed a heavier weight, with the greatest contrast between the sexes occurring at 181 days. The analysis of the three most contrasting families (AA1, AA9 and AA14) showed that the asymptotic value for weight was higher (P<0.05) in family AA9 (3,926.3 g) than in family AA14 (3,251.6 g), but specific growth rate and age at the inflection point did not differ significantly between families. In conclusion, two of the 20 families were superior; males exhibited a greater growth, mainly in the period of 181 days; and the growth curve differed between the families, especially for asymptotic weight.

Understanding Pacemaker-Induced Cardiomyopathy Incidence and Predictors in Patients with Right Ventricular Pacing: A Systematic Review

This study aimed to figure out the incidence and predictors of pacemaker-induced cardiomyopathy (PICM) in patients with right ventricular (RV) pacing. We systematically searched in PubMed on March 18, 2020, for English language abstract and full-article journals, using the following criteria: pacemaker induced cardiomyopathy AND right ventricular AND pacemaker AND patients AND human NOT implantable cardioverter defibrillator NOT ICD NOT animal. Four studies were included in this review after filtering 35 studies through year of publication and abstract selection. The average PICM incidence from 1,365 patients included from the four studies was 10.7 to 13.7%. One study stated that preimplantation left ventricular ejection fraction (LVEF) was the predictor for the development of PICM. Three studies mentioned that RV pacing burden was the predictor for the development of PICM. However, the percentage differ in three studies: ≥20, >40, and 60%. In addition, one of the studies also included interventricular dyssynchrony as another predictor. The incidence of PICM in patients with RV pacing ranged from 10.7 to 13.7%. Preimplantation LVEF, interventricular dyssynchrony, and burden of RV pacing are reported as the predictors for the development of PICM in patients with RV pacing.

Direct selection for phenotypic traits in carrot genotypes

ABSTRACT Selection of more productive carrot genotypes is fundamental for crop breeding programs aiming to increase productivity and reduce cost production. Thus, the aim of this work was to evaluate gains from direct selection and to measure its effects on other agronomic traits of interest in carrots. Thirty six carrot genotypes were evaluated in two experiments: the first, sown in the second half of November 2016 and the second one in the first week of March 2017. The experimental plots covered a useful area of 1.5 m2, in transversal rows and 0.10-m double spacing between single rows x 0.20-m between double rows in a randomized block design with 3 replicates. At 90 days, the incidence of leaf blight was evaluated using a note scale and 100 days after sowing, roots were harvested measuring the number and mass of total, commercial and non-commercial roots of each plot. The direct selection of commercial root mass allowed to estimate indirect and expressive gains for most evaluated traits, allowing to select seven genotypes (populations 758, 751, 737, 736, 735, 744 and 742) which can be released as cultivar or for the formation of a broader genetic-based population.

ReCAP: Pattern of Duplicate Presentations at National Hematology-Oncology Meetings: Influence of the Pharmaceutical Industry

CONTEXT AND QUESTION ASKED: The American Society of Clinical Oncology (ASCO) and the American Society of Hematology (ASH) annual meetings are two of the largest conferences in the fields of hematology and oncology. These meetings are attended by physicians, researchers, pharmaceutical industry colleagues, and representatives from the media and business sectors. The intention of both societies, as stated in their submission guidelines, is to accept abstracts that have not previously been presented. These policies are presumably in place to minimize redundancy and, due to time and space constraints, allow the largest number of researchers to present their findings. Hence, we asked, are there duplicative presentations at these two large meetings, and if so, how often do they occur? METHODS—WHAT WE DID: To date, however, the success of the societies in eliminating duplication has not been carefully analyzed. In addition, the motivations behind re-presentation have not been evaluated objectively. Therefore, we conducted a review of 327 malignant hematology (non-transplantation) abstracts presented at ASCO 2010 and compared them with prior and subsequent ASCO and ASH meetings to evaluate the incidence of duplicate presentations and their relationship to funding sources over a 2 year time frame. RESULTS—WHAT WE FOUND: Our analysis indicated that 31% of accepted abstracts were duplicated during the 2-year time frame, with those indicating pharmaceutical support three times more likely to be duplicated ( Figure 1 ). IMPLICATIONS FOR PRACTICE & LIMITATIONS OF DATA: These findings suggest that a substantial number of duplicative abstracts are re-presented, with a disproportionate number having pharma sponsorship. The motivations for duplication are varied but may include an influence of pharma marketing strategies. Although these results are limited by our search strategy and to this 2-year time frame, the results were similar when we analyzed ASH and ASCO 2014 leukemia abstracts. These findings demonstrate the need for a more effective abstract selection system and that further study of the role of marketing in large meetings such as ASCO and ASH would be appropriate.
