Selección masal por peso y coloración en tilapia roja

Para evaluar la efectividad de la selección masal por color y peso se analizaron dos generaciones (G1 y G2) de alevinos de tilapia roja Oreochromis sp. De 40.000 larvas a la sexta semana se eliminaron los alevinos manchados y blancos y a las 14 semanas se separaron por sexos. Se midió el peso (g), la longitud total (cm), la altura (cm) y el ancho (cm) de 150 individuos a las 6, 14 y 24 semanas de edad. En la semana 24 se escogieron 150 machos y 450 hembras con las coloraciones deseables y mayor peso. La selección resultó efectiva para coloración en G2, puesto que la proporción de individuos rojos se incrementó en 15% con respecto a los testigos. Entre generaciones (G1 y G2) el efecto de la selección fue positivo, debido a que la proporción de rojos se incrementó de 64% a 84% y se redujo la de manchados de 31% a 13%. En ambas generaciones los machos fueron significativamente más pesados que las hembras. Se encontraron notables diferencias entre generaciones para peso y talla, puesto que los selectos superaron al control en 27% y 8% (G1) y en 22% y 11% (G2) para el peso y la talla, respectivamente

Investigación pedagógica en Bogotá : horizontes desde el programa Maestros y Maestras que Inspiran 2021

251 páginasPublicación resultado de la sistematización de experiencias de docentes participantes en el programa Maestros y Maestras que Inspiran, 2021. «Si quisiéramos mejorar la educación deberíamos mejorar la calidad de sus docentes […] Esto implica cultivar la curiosidad, la mirada crítica y buscarle significado al mundo que nos rodea, apreciando dónde está lo importante y siendo capaces de entender y describir por qué es importante. Los textos —de este compilado— dan cuenta de esas búsquedas y aquellos encuentros […] los autores nos dicen, de diferentes maneras, que la educación es la gran oportunidad, que una nueva escuela es necesaria y posible» Agustín Porre

Experiencias docentes en tiempo de pandemia

El texto Experiencias docentes en tiempo de pandemia está estructurado en dos partes: 1. Discusiones necesarias sobre la educación superior en tiempo de pandemia. 2. Prácticas docentes en época de pandemia expresadas a través del relato. En la primera parte, se presenta un conjunto de nueve artículos que buscan fundamentar teóricamente la situación actual de la educación conforme a las circunstancias que estamos viviendo, de manera que: Robert Fernando Bolaños Vivas, en su artículo La filosofía de la Educación ante la crisis sanitaria COVID-19, una oportunidad de humanización, considera que la crisis sanitaria de la COVID-19 ha puesto de manifesto la profunda crisis humana que pone a prueba la calidad de los seres humanos, razón por la cual el autor intenta demostrar la deficiente respuesta antropológica a las complejas exigencias y complejidades de la crisis sanitaria provocada por la COVID- 19, en este sentido, en el artículo reflexiona sobre la dimensión de la alteridad, la historicidad y la temporalidad humana

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Etude de la biochimie de la digestion des phaséolines du haricot (Phaseolus vulgaris) in vitro et in vivo : ( effets du type de phaséoline et du traitement thermique, et impact sur la muqueuse intestinale du rat )

L objectif de cette thèse était d étudier les effets de la phaséoline purifiée sur la digestion des protéines, la morphologie etles activités enzymatiques intestinales chez le rat, et la susceptibilité à la protéolyse in vitro d un grand nombre (n=43) de variétés de phaséolines purifiées. Les phaséolines crues présentaient une faible digestibilité fécale (19-20 %) indépendamment du type de phaséoline étudié. Le type (S, T ou I) de phaséoline a influencé la concentration idéale des phaséolines et de certains de leurs peptides lorsqu elle a été consommée crue. Une incorporation de phaséoline supérieure à 50 % des protéines alimentaires a affecté la morphologie et les activités enzymatiques intestinales et les pertes iléales de protéines endogènes (amylase pancréatique et trypsine). Le traitement thermique a fait disparaître ces effets tout en améliorant notablement la digestion intestinale et la digestibilité fécale (77-80 %) des phaséolines. La susceptibilité des 43 variétés de phaséolines à la protéolyse in vitro a fortement varié tant avant (11-27 %) qu après 57-96 %) traitement thermique. Nous avons confirmé à partir des compositions en acides aminés et de la protéolyse in vitro que les acides aminés soufrés des phaséolines sont les principaux acides aminés limitant pour la croissance. En conclusion, ce travail de thèse précise les effets spécifiques des phaséolines sur le tube digestif in vivo et leur susceptibilité à la protéolyse in vitro. Il ouvre des perspectives d amélioration de la qualité nutritionnelle des haricots destinés à l homme, à travers la sélection de variétés à teneur en acides aminés limitant et/ou à susceptibilité de la phaséoline à la protéolyse in vitro, plus élevées.The aim of this PhD thesis was to investigate the effects of purified phaseolin on protein digestin and intestinalmorphlogy and enzyme activites in the rat, and the susceptiblity of large numbers (43) of purified phaseolin varieties to proteolysis in vitro. Unheated phaseolin displayed low faecal digestibility (19-20 %), irrespective of the type of phaseolin studied. The type (S, T or I) of phaseolin, when unheated influenced the ileal concentration of phaseolin and of some of its digestion products. An incorporation level of phaseolin superior to 50 % of dietary protein affected intestinal morphology and enzymes activities and increased ileal losses of endogenous protein (pancreatic amylase and typsin). Thermal treatment obrogated these effects while improving drastically intestinal digestion and faecal digestibility (77-80 %) of phaseolin. The susceptibility of the 43 purified phaseolin varieties varied widely both without (11-27 %) and after (57-96 %) thermal treatment. We have confirmed from amino acid composition and in vitro proteolysis that sulphur amino acids are the main limiting amino acids in phaseolins. In conclusion, this work highlights the specific effects of phaseolin on the gut in vivo and their susceptibility to proteolysis in vitro. This work opens news perspectives for improving the nutritional quality of common bean for humans, based on selecting varieties with higher contents of limiting amino acids and/or higher susceptibility of phaseolin to proteolysis in vitro.RENNES-Agrocampus-CRD (352382323) / SudocSudocFranceF

Selección masal por peso y coloración en tilapia roja Mass selection by weight and coloration in red tilapia

Para evaluar la efectividad de la selección masal por color y peso se analizaron dos generaciones (G1 y G2) de alevinos de tilapia roja Oreochromis sp. De 40.000 larvas a la sexta semana se eliminaron los alevinos manchados y blancos y a las 14 semanas se separaron por sexos. Se midió el peso (g), la longitud total (cm), la altura (cm) y el ancho (cm) de 150 individuos a las 6, 14 y 24 semanas de edad. En la semana 24 se escogieron 150 machos y 450 hembras con las coloraciones deseables y mayor peso. La selección resultó efectiva para coloración en G2, puesto que la proporción de individuos rojos se incrementó en 15% con respecto a los testigos. Entre generaciones (G1 y G2) el efecto de la selección fue positivo, debido a que la proporción de rojos se incrementó de 64% a 84% y se redujo la de manchados de 31% a 13%. En ambas generaciones los machos fueron significativamente más pesados que las hembras. Se encontraron notables diferencias entre generaciones para peso y talla, puesto que los selectos superaron al control en 27% y 8% (G1) y en 22% y 11% (G2) para el peso y la talla, respectivamente.In order to evaluate the effectiveness of mass selection by color and weight, two generations (G1 y G2) of red tilapia Oreochromis sp. were analyzed. 40000 larvae were used, at the sixth week fries with black spots and white were eliminated, and at week 14, the fishes were separated by sex. The weight (g), length, height and width (cm) were measured in a sample of 150 individuals at 6, 14 and 24 weeks. At week 24, the best 150 males and 450 females with desirable colorations and higher weight were chosen. The selection was effective for coloration in G2, because proportion of red individuals increased in 15% compared to the control. The effect of the selection between generations (G1 y G2) was positive because proportion of red fries increased from 64% to 84%, and the spotted ones were reduced from 31% to 13%. In both generations males were significantly weighted than the females. For weight and size, significant differences between generations were found due to the fact that the selected ones were over the control on 27% and 8% (G1) and 22% and 11% (G2) for weight and size respectively
