Background: Alpacas have reproductive traits such as induced ovulation and a higher gestation rate in the left uterine horn (LUH). Additionally, low fertility and high embryonic mortality are significant challenges in alpaca breeding. To address these issues, it is essential to study the histological changes occurring in the uterine wall during day 8 of the luteal phase (LP). Aim: This research aims to describe these changes in alpacas with induced ovulation using GnRH or copulation. Methods: The study was conducted on 8 sexually mature fertile alpacas with a preovulatory follicle of ≥ 7 mm. Ovulation was induced with GnRH (G1, n = 3) and natural mating' (G2, n = 5), confirmed by ultrasound showing the disappearance of the follicle and formation of the corpus luteum (CL). On day 8 of the LP, samples of the uterine wall from the right and LUHs were obtained through a midline laparotomy....

Background: Neotropiella is a genus of springtails which can be of medium size (2 mm) or relatively long (5 mm). These springtails live in leaf litter, under the bark of dead trees or in decomposing wood, mainly in the Neotropical Region and are often collected by litter samples on Berlese funnels or by pitfall traps. Most species have been described, based on relatively few specimens and chaetotaxy of several species is incomplete. New information: A new species within Neotropiella was discovered in recent pitfall trap collections from Peru. Neotropiella peruana sp. n. was taxonomically treated and studied under both phase contrast and scanning electron microscopy. It is similar to N. insularis from Brazil, but smaller with only 4 mandibular teeth (vs. 5) and with well-developed unguis lateral teeth. Intraspecific variation of the new species is provided. We also present the first DNA b...

Two methods of dehydration of strawberries (Fragaria chiloensis 1 .) ha ve been studied: spray-drying and freezedrying. It has been found that the optimum sequence for the drying operation is as follows: selection/classification , washing, steaming, pulp-extraction, conditioning and freeze-drying. The efficiency over the total solids obtained with this method is 86.48% compared to 66.02% when using spray-drying. The strawberry pulp was conditioned by water dilution of 1:1. For spray-drying, the pH was adjusted to 4.1 with NaHC03 , and for capsulating purposes were used: 1% CMC and 1.60% gum arabic by weight of pul p. For the dehydration by freeze-drying it was used: 1.2% CMC, 2.0% dextrine anda control sample without any additives. lt was found that for dehydration by spray-drying, 1.60% of gum arabic anda temperature of 1 802C for the hot air at the inlet should be u sed. For dehydratio...

Introduction: Despite the growing awareness of the importance of knowledge in biostatistics, many investigations worldwide have found that medical students have a poor understanding of it. Objective: To determine the percentage of Peruvian medical students with sufficient biostatistics knowledge and the associated factors. Methods: Cross-sectional analytical study. Application of a virtual survey to medical students from different faculties in Peru. Results: 56.46% of medical students have insufficient knowledge of biostatistics. A statistically significant association was found for those who were 25 years of age or older (aPR: 1.195; 95% CI 1.045 - 1.366; p=0.009); being between the 9th and 12th semester (aPR: 1.177; 95% CI 1.001 - 1.378; p=0.037) and medical internship (aPR: 1.373; 95% CI 1.104 - 1.707; p=0.004); take an external course in biostatistics, epidemiology or research (aPR: ...

Introducción: En crisis sanitarias mundiales los medios de comunicación son importantes para informar sobre los temas relevantes a la población. Objetivo: Caracterizar y encontrar asociaciones de la percepción de miedo o exageración que transmiten los medios de comunicación en la pandemia del COVID–19 en ciudades del Perú. Métodos: Estudio transversal analítico y multicéntrico. Se realizó una encuesta virtual a 4009 personas, en 17 ciudades del Perú, del 15-20 de marzo del 2020. El instrumento, previamente validado, evaluó tres factores: la exageración de los medios; el miedo generado y la comunicación que provenía del personal de salud, familiares y amigos. Los coeficientes de relación y los valores p fueron calculados a través del uso de modelos lineales generalizados, con familia Gaussian y función de enlace identity. Se consideraron a los valores de p <0,05 como ...
