Evaluación del efecto de un suplemento mineral sobre la calidad seminal de cerdos reproductores

It was evaluated the addition effect of different concentrations of a mineral supplement, on the seminal characteristics of boars. The essay was developed in Sincelejo municipality. The experiment consisted in three cycles of mineral supplementation, where was supplied 10, 20 and 30 g/day daily in every pig, per cycle. Every cycle had a duration of 55 days, obtaining 1 ejaculate/pig/week (10 ejaculates/cycle). The seminal collects where taken making use of the hand gloved method. After the collect where made, the semen was transported to the laboratory, where it was processed and realized its respective evaluation of seminal quality (macroscopic and microscopic variables). The results evidenced that seminal volume, spermatic motility (individual, progressive), spermatic morphology (tails) and spermatic vitality, showed probability values associated to a lineal effect (P<0,05), related to an increase in the supplementation level. The spermatic motility (gross), spermatic morphology (normal) and spermatic concentration, showed probability values associated to a quadratic effect (P<0,05) of supplementation level. On the other hand, spermatic morphology (heads, cytoplasmic droplets) weren’t affected by the treatments (P>0,05). Finally, it was evidenced an effect of the supplementation levels on seminal aspect, but neither pH nor seminal color (P>0,05). It can be concluded that dietary micromineral supplementation favors some seminal variables such as volume and concentration, maintaining the others characteristics, within normal parameters.Se evaluó el efecto de la adición de diferentes concentraciones de un suplemento mineral, sobre la calidad seminal en cerdos machos adultos usados para la reproducción. El ensayo se realizó en el municipio de Sincelejo. El experimento constó de tres ciclos de suplementación mineral, en donde se suministraron 10, 20 y 30 g/día en cada cerdo por ciclo. Cada ciclo duró 55 días, y se obtuvo 1 eyaculado/cerdo/semana (10 eyaculados/ciclo). Las colectas seminales fueron realizadas con el método de mano enguantada. Posterior a cada colecta, el semen fue transportado al laboratorio en donde se procesó y se realizó su respectiva evaluación de calidad espermática (variables macroscópicas y microscópicas). Los resultados evidenciaron que el volumen seminal, la motilidad espermática (individual, progresiva), la morfología espermática (colas) y la vitalidad espermática, mostraron valores de probabilidad asociados a un efecto lineal (P<0,05) relacionado a un incremento en el nivel de suplementación. La motilidad espermática (masal), la morfología espermática (normales) y la concentración espermática, presentaron valores de probabilidad asociados a un efecto cuadrático (P<0,05), del nivel de suplementación. Por otro lado, la morfología espermática (cabezas, colas citoplasmáticas) no fueron afectadas por los tratamientos evaluados (P>0,05). Finalmente, se evidenció un efecto de los niveles de suplementación sobre el aspecto seminal (P<0,05), pero no sobre el pH y color seminal (P>0,05). Se puede concluir que la suplementación dietaria micromineral favorece algunas variables seminales tales como el volumen y la concentración, manteniendo las demás características, dentro de los parámetros normales

Healthcare workers hospitalized due to COVID-19 have no higher risk of death than general population. Data from the Spanish SEMI-COVID-19 Registry

Aim To determine whether healthcare workers (HCW) hospitalized in Spain due to COVID-19 have a worse prognosis than non-healthcare workers (NHCW). Methods Observational cohort study based on the SEMI-COVID-19 Registry, a nationwide registry that collects sociodemographic, clinical, laboratory, and treatment data on patients hospitalised with COVID-19 in Spain. Patients aged 20-65 years were selected. A multivariate logistic regression model was performed to identify factors associated with mortality. Results As of 22 May 2020, 4393 patients were included, of whom 419 (9.5%) were HCW. Median (interquartile range) age of HCW was 52 (15) years and 62.4% were women. Prevalence of comorbidities and severe radiological findings upon admission were less frequent in HCW. There were no difference in need of respiratory support and admission to intensive care unit, but occurrence of sepsis and in-hospital mortality was lower in HCW (1.7% vs. 3.9%; p = 0.024 and 0.7% vs. 4.8%; p<0.001 respectively). Age, male sex and comorbidity, were independently associated with higher in-hospital mortality and healthcare working with lower mortality (OR 0.211, 95%CI 0.067-0.667, p = 0.008). 30-days survival was higher in HCW (0.968 vs. 0.851 p<0.001). Conclusions Hospitalized COVID-19 HCW had fewer comorbidities and a better prognosis than NHCW. Our results suggest that professional exposure to COVID-19 in HCW does not carry more clinical severity nor mortality

Kwapa: Gente del río. Estrategias transmedia de impacto social

El PAP Alter Código, período Primavera 2023, trabajó con los dos proyectos que se han venido trabajando en semestres anteriores: el videojuego A Orillas del río y el documental Déjennos pescar. Ambos proyectos parten de la metodología interdisciplinaria y colaborativa con miembros de la comunidad Cucapá para crear representaciones audiovisuales no estigmatizantes, que detonen el sentido de comunidad y refuercen su acervo cultural. El videojuego A Orillas del río es del género point and click, de vista isométrica, el cual está inspirado en el cuento oral tradicional El zorro y el coyote, que busca ser una herramienta lúdica de aprendizaje para reforzar el aprendizaje de la lengua Cucapá en los niños. Los resultados obtenidos fueron el demo del nivel uno (escenas uno y dos); colorimetría, arcos de personajes principales; programación de minijuegos. Dentro del documental ‘Déjennos pescar’ los resultados fueron un montaje, una clasificación del material grabado con transcripciones de audio, mientras que en la parte de estrategia de impacto se creó un manual de uso de redes sociales con colorimetría, tipografía, estilo de voz, tipo de contenido según la red social, para los futuros integrantes del equipo.ITESO, A.C

Repositioning of the global epicentre of non-optimal cholesterol

High blood cholesterol is typically considered a feature of wealthy western countries(1,2). However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world(3) and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health(4,5). However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol-which is a marker of cardiovascular riskchanged from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million-4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world.Peer reviewe

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe

MUSiC : a model-unspecific search for new physics in proton-proton collisions at root s=13TeV

Results of the Model Unspecific Search in CMS (MUSiC), using proton-proton collision data recorded at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), are presented. The MUSiC analysis searches for anomalies that could be signatures of physics beyond the standard model. The analysis is based on the comparison of observed data with the standard model prediction, as determined from simulation, in several hundred final states and multiple kinematic distributions. Events containing at least one electron or muon are classified based on their final state topology, and an automated search algorithm surveys the observed data for deviations from the prediction. The sensitivity of the search is validated using multiple methods. No significant deviations from the predictions have been observed. For a wide range of final state topologies, agreement is found between the data and the standard model simulation. This analysis complements dedicated search analyses by significantly expanding the range of final states covered using a model independent approach with the largest data set to date to probe phase space regions beyond the reach of previous general searches.Peer reviewe

Measurement of prompt open-charm production cross sections in proton-proton collisions at root s=13 TeV

The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe
