Se realizó un estudio de la diversidad de especies del género Vibrio asociada a mortalidades larvarias masivas en la concha de abanico (Argopecten purpuratus) cultivadas en “hatchery”. Las muestras fueron tomadas en seis desoves de concha de abanico en un “hatchery”, tanto en individuos en el fondo del tanque de cultivo como suspendidos en la columna de agua, a 72 horas posteriores al desove a 19 °C. Se transportaron las muestras a una temperatura de 5 ± 2 °C, a los laboratorios de la Universidad Peruana Cayetano Heredia (UPCH), donde se incubaron a 20 °C en los medios de Agar Marino (AM) y Tiosulfato Citrato Bilis Sacarosa (TCBS). Posterior a la caracterización morfológica, se enfrentó los aislados al agente vibriostático O/129. Los aislados se caracterizaron bioquímicamente utilizando el sistema comercial miniaturizado API® 20E. Se identificó al Vibrio alginolyticu...

The goal of search indicators cognitive, affective and social good teaching practices, research motivate this descriptive and correlational in nature. The three selected variables have been studied with instruments that assess irrational beliefs, assertiveness and the judgment criterion was the school violence. The first two formats that validity and reliability enjoyed by the authors and countless investigations, and the third a specific construction for this research, the same that have been subjected to analysis of statistical consistency, and the content and conceptual extension theoretical systems that sustain.

The research is descriptive and comparative aims to disseminate the results of psychological research on mindsets of self-talk, positive and negative, and learning styles of students in San Marcos belonging to each of the five academic field organizing vocational training: Health Sciences, Basic Sciences, Engineering, Business and Humanities. For purposes of the study has used two instruments: (1) self-talk Inventory (Calvete, Esteve, Landin), comprising two subscales: positive and negative¸ both with the technical specifications in order to draw conclusions valid and reliable, so we the original statistics, alpha coefficients of 0.89 for negative self-talk scales and 0.86, 0.79 and 0.87 for the subscales of thoughts related to anxiety, depression and anger, respectively. On the other hand, the alpha coefficients were 0.82 for positive self-Scale and 0.72, 0.76 and 0.55 for the subscale...

Investigation takes as reference the contributions from Cognitiva Psychologist on mental models, in the proposals of Johnson-Laird (1996), Moreira (1997) and Vergnaud (1996), as well as construction cognitive of the concept of university quality in its different dimensions and proposals. The investigation is exploratory, descriptive and comparative. The objectives of investigation are the following ones: 1. Identify and to characterize the mental models developed by the university students, 2. Determine the characteristics and attributes and to compare them in the five academics areas who organize the studies in Universidad Nacional Mayor de San Marcos. We have developed the analysis method of content, based in connotative meanings of quality, by selecting concepts accepted in technical approaches and representations made by the students. It has identified eighteen parameters of quality ...

Purpose: Prognostic value of pathologic complete response (pCR) and extent of pathologic response attained with anthracycline-free platinum plus taxane neoadjuvant chemotherapy (NAC) in triple-negative breast cancer (TNBC) is unknown. We report recurrence-free survival (RFS) and overall survival (OS) according to degree of pathologic response in patients treated with carboplatin plus docetaxel NAC. Patients and methods: One-hundred and ninety patients with stage I-III TNBC were treated with neoadjuvant carboplatin (AUC6) plus docetaxel (75 mg/m2) every 21 days × 6 cycles. pCR (no evidence of invasive tumor in breast and axilla) and Residual cancer burden (RCB) were evaluated. Patients were followed for recurrence and survival. Extent of pathologic response was associated with RFS and OS using the Kaplan-Meier method. Results: Median age was 51 years, and 52% were node-positive. pCR and ...
