Se recolectaron 89 larvas de Harrisina sp en una huerta de vid en el Valle de San Vicente, Baja California, mismas que fueron trasladadas al laboratorio de Parasitología de la Facultad de Ingeniería y Negocios San Quintín (FINSQ), donde se mantuvieron a una temperatura ambiente que oscilaba entre los 28±2º C y una Humedad Relativa de 60-70 % dentro de una jaula entomológica donde se estuvieron alimentando con follaje del mismo cultivo hasta completar su ciclo de vida y detectar la muerte a causa de enemigos naturales. Se determinó una duración de 80 días desde la ovipostura hasta el estado adulto de la palomilla; así mismo, se obtuvieron 7 adultos de la mosca parasitoide Ametadoria misella (Diptera: Tachinidae), lo que representa un 7.86 % de parasitoidismo natural por parte del taquínido.

To determine the location and grade of prostate cancer diagnosed by transperineal template-guided mapping (TTMB) after negative transrectal ultrasound-guided (TRUS) biopsy. This analysis consisted of 1118 consecutive patients who underwent TTMB from January 2005 to August 2015. Eight hundred thirty-five underwent TTMB after at least 1 negative TRUS biopsy and 283 underwent TTMB as the first biopsy procedure. The study population was divided into cohorts based on the number of prior TRUS biopsy sessions (0, 1, 2, and ≥3). No patient underwent multiparametric magnetic resonance imaging. Differences in location and cancer grade detected on TTMB were evaluated as a function of the number of prior TRUS biopsies. Of the 1118 patients, 679 were diagnosed with prostate cancer. This included 208, 325, 104, and 42 patients who underwent 0, 1, 2, and ≥3 prior TRUS biopsies. The incidence of cancer detection on TTMB decreased as the number of prior TRUS biopsies increased (73.5% vs. 62.4% vs. 51.7% vs. 37.2%, P<0.001); however, it became increasingly likely that TTMB would detect anterior prostate only as the number of prior TRUS biopsies increased (P=0.007). Moreover, the incidence of high grade cancer (Gleason score ≥7) in the anterior gland increased with the number of previous TRUS biopsies. TTMB detected prostate cancer in over half of the patients with one or more negative TRUS biopsies. The majority of TTMB detected cancers were Gleason score ≥7. As the number of prior TRUS biopsies increased, there was a commensurate increase in the proportion of high-grade, anterior only disease.

Total body irradiation (TBI) is a specialized radiotherapy technique. It is frequently used as a component of treatment plans involving hematopoietic stem cell transplant for a variety of disorders, most commonly hematologic malignancies. A variety of treatment delivery techniques, doses, and fractionation schemes can be utilized. A collaborative effort of the American College of Radiology and American Society for Radiation Oncology has produced a practice guideline for delivery of TBI. The guideline defines the qualifications and responsibilities of the involved personnel, including the radiation oncologist, physicist, dosimetrist, and radiation therapist. Review of the typical indications for TBI is presented, and the importance of integrating TBI into the multimodality treatment plan is discussed. Procedures and special considerations related to the simulation, treatment planning, treatment delivery, and quality assurance for patients treated with TBI are reviewed. This practice guideline can be part of ensuring quality and safety in a successful TBI program.
