Relación entre factores de regulación externa y motivación en alumnos de posgrado de Universidad Autónoma del Noreste campus Monclova durante emergencia sanitaria por SARS-CoV2

La contingencia sanitaria causada por covid-19  ha afectado sistemas gubernamentales, económicos, de salud y educativos a lo largo del mundo. En el sistema educativo ha obligado a las instituciones a migrar súbitamente de modelos presenciales a modelos de educación a distancia o virtuales. En menor escala durante esta pandemia las personas se han visto impactadas con problemas de salud, emocionales, económicos y laborales. Los alumnos de maestrías de salud ocupacional y terapia familiar de la Universidad Autónoma del Noreste campus Monclova no están ajenos a estos problemas que pueden llevarlos a desmotivación académica y en casos graves deserción del estudiante, por lo que esta investigación tiene por objetivo verificar estadísticamente la existencia de relación entre la motivación por adquirir nuevos conocimientos y los factores de regulación externa del alumno de maestrías en salud ocupacional y terapia familiar de la Universidad Autónoma del Noreste campus Monclova durante emergencia sanitaria por SARS-CoV2. La investigación se llevó durante febrero a marzo de 2021 en la Universidad Autónoma del Noreste campus Monclova teniendo como muestra 35 alumnos de posgrado de maestrías de Salud Ocupacional y Terapia Familiar. Para recabar información se aplicó el instrumento “Escala de Motivación Educativa”. Al realizar prueba de correlación de Spearman en variables se obtiene que “no existe relación significativa entre los factores de regulación externa y la motivación para adquirir conocimientos por parte de los alumnos de las maestrías de salud ocupacional y terapia familiar de la Universidad Autónoma del Noreste campus Monclova durante emergencia sanitaria por SARS-CoV2

Colorectal cancer after bariatric surgery (Cric-Abs 2020): Sicob (Italian society of obesity surgery) endorsed national survey

Background The published colorectal cancer (CRC) outcomes after bariatric surgery (BS) are conflicting, with some anecdotal studies reporting increased risks. The present nationwide survey CRIC-ABS 2020 (Colo-Rectal Cancer Incidence-After Bariatric Surgery-2020), endorsed by the Italian Society of Obesity Surgery (SICOB), aims to report its incidence in Italy after BS, comparing the two commonest laparoscopic procedures-Sleeve Gastrectomy (SG) and Roux-en-Y gastric bypass (GBP). Methods Two online questionnaires-first having 11 questions on SG/GBP frequency with a follow-up of 5-10 years, and the second containing 15 questions on CRC incidence and management, were administered to 53 referral bariatric, high volume centers. A standardized incidence ratio (SIR-a ratio of the observed number of cases to the expected number) with 95% confidence intervals (CI) was calculated along with CRC incidence risk computation for baseline characteristics. Results Data for 20,571 patients from 34 (63%) centers between 2010 and 2015 were collected, of which 14,431 had SG (70%) and 6140 GBP (30%). 22 patients (0.10%, mean age = 53 +/- 12 years, 13 males), SG: 12 and GBP: 10, developed CRC after 4.3 +/- 2.3 years. Overall incidence was higher among males for both groups (SG: 0.15% vs 0.05%; GBP: 0.35% vs 0.09%) and the GBP cohort having slightly older patients. The right colon was most affected (n = 13) and SIR categorized/sex had fewer values < 1, except for GBP males (SIR = 1.07). Conclusion Low CRC incidence after BS at 10 years (0.10%), and no difference between procedures was seen, suggesting that BS does not trigger the neoplasm development

Rendimiento de forraje y composición morfológica de maíces nativos en condiciones semiáridas

Environmental conditions in semi-arid areas limit the productivity of forage species used in animal feed; however, corn (Zea maysL.) has a wide adaptation to different environmental conditions of temperature, precipitation, altitude, soil, among others. The objective of the present study was to evaluate the yieldand morphological composition of ten native corn genotypes, a hybrid and a synthetic variety, during the cycle Spring-Summer 2017. A randomized complete block experimental design was used, and an analysis of variance was performed; the means of the treatments were compared with the Tukey test. The variables evaluated were: yield of total dry matter (TDM), and by morphological component: leaf (lDM), stem (sDM), ear(eDM), panicle (pDM) and dead matter (dmDM), plant height (PH), number of leaves (NL), leaf length (LL), leaf width (LW) and the leaf/stem ratio (L/S). The highestand lowest TDM yieldwas obtained by the Raton×Tuxpeño Norteño genotype and the A6-069-B hybrid, with 8 888 and 3 113 kg DM ha-1, respectively. The highest height (180 cm) was obtained by the genotypes Raton×Tuxpeño Norteño and Olotillo×Tuxpeño. The largest number of leaves number was presented by the genotype Tuxpeño Norteño×Olotillo with 11.6. The largest leaf:stem ratio (2.1) was in the synthetic variety Breve Padilla. More research is needed on the improvement by recurrent selection of the Raton×Tuxpeño Norteño genotype to obtain a higher yield and nutritional value in corn fodderLas condiciones ambientales en zonas semiáridas limitan la productividad de especies forrajeras empleadas en la alimentación animal; sin embargo, el maíz (Zea mays L.) presenta una amplia adaptación a diferentes condiciones ambientales de temperatura, precipitación, altitud, suelo entre otras. El objetivo del presente estudio fue evaluar el rendimiento y composición morfológica de diez genotipos de maíces nativos, un híbrido y una variedad sintética, durante el ciclo primavera-verano de 2017. Se utilizó un diseño experimental de bloques completos al azar y se realizó un análisis de varianza, las medias de los tratamientos se compararon con la prueba de Tukey. Las variables evaluadas fueron: rendimiento de materia seca total (MST) y por componente morfológico: hoja (MSh), tallo (MSt), mazorca (MSmz), panícula (MSp) y materia muerta (MSmm), altura de planta (AP), número de hojas (NH), longitud de hoja (LH), ancho de hoja (AH) y la relación hoja/tallo (H/T). El mayor y menor rendimiento de MST, lo obtuvo el genotipo Ratón×Tuxpeño Norteño y el híbrido A6-069-B, con 8 888 y 3 113 kg MS ha-1, respectivamente. La mayor altura (180 cm) la obtuvieron los genotipos Ratón×Tuxpeño Norteño y Olotillo×Tuxpeño. El mayor número de hojas lo presentó el genotipo Tuxpeño Norteño×Olotillo con 11.6. La mayor relación hoja/tallo (2.1) fue en la variedad sintética breve Padilla. Es necesario realizar más investigación en el mejoramiento por selección recurrente del genotipo Ratón×Tuxpeño Norteño para obtener un mayor rendimiento y valor nutritivo en el forraje de maíz

Seed Physiological Potential of Capsicum annuum var. glabriusculum Genotypes and Their Answers to Pre-Germination Treatments

Piquin pepper (Capsicum annuum var. glabriusculum) is an important species that supports the economy of rural households; it is part of Mexican gastronomy and it is a highly valuable phytogenetic resource. There has been recent interest in domesticating and exploiting piquin pepper commercially, which has been limited until now due to the low germination rate, and this work had the purpose of promoting germination and determining the physiological capacity of genotypes. Ten piquin pepper genotypes from different geographical origins in Mexico were submitted to 11 pre-germination treatments. A completely randomized experimental design was carried out with arrangement in split-plot. The large plot had the treatments and the small plot had the genotypes. The results showed differences (p < 0.01) among treatments, genotypes, and treatment–genotype interaction. On one hand, treatments gibberellic acid (GA) and mechanical scarification + gibberellic acid (MSGA) increased the physiological potential of genotypes, reaching the highest values of germination speed (GS), germination index (IG) and germination percentage (GP); as well as the lowest values of dead seeds (DS) and hard Seeds (HS). In turn, the genotypes that presented the same condition were G8, G7, and G10. Regarding the interaction, each variable had a different condition. In conclusion, we can increase the physiological potential and solve the dormancy of piquin pepper seed by applying gibberellic acid. Likewise, the best genotypes were G8 and G10

IMMUNOREACT 6: weak immune surveillance characterizes early-onset rectal cancer

Background: Colon cancer in young patients is often associated with hereditary syndromes; however, in early-onset rectal cancer, mutations of these genes are rarely observed. The aim of this study was to analyse the features of the local immune microenvironment and the mutational pattern in early-onset rectal cancer. Methods: Commonly mutated genes were analysed within a rectal cancer series from the University Hospital of Padova. Mutation frequency and immune gene expression in a cohort from The Cancer Genome Atlas ('TCGA') were compared and immune-cell infiltration levels in the healthy rectal mucosa adjacent to rectal cancers were evaluated in the IMMUNOlogical microenvironment in REctal AdenoCarcinoma Treatment 1 and 2 ('IMMUNOREACT') series. Results: In the authors' series, the mutation frequency of BRAF, KRAS, and NRAS, as well as microsatellite instability frequency, were not different between early- and late-onset rectal cancer. In The Cancer Genome Atlas series, among the genes with the most considerable difference in mutation frequency between young and older patients, seven genes are involved in the immune response and CD69, CD3, and CD8β expression was lower in early-onset rectal cancer. In the IMMUNOlogical microenvironment in REctal AdenoCarcinoma Treatment 1 and 2 series, young patients had a lower rate of CD4+ T cells, but higher T regulator infiltration in the rectal mucosa. Conclusion: Early-onset rectal cancer is rarely associated with common hereditary syndromes. The tumour microenvironment is characterized by a high frequency of mutations impairing the local immune surveillance mechanisms and low expression of immune editing-related genes. A constitutively low number of CD4 T cells associated with a high number of T regulators indicates an imbalance in the immune surveillance mechanisms
