ECOLOGICAL NICHE OF SEMIDOMESTICATED POPULATIONS OF Capsicum pubescens RUIZ & PAV. BASED ON ACCESSIONS FROM VERACRUZ, MEXICO

Para cultivar una especie silvestre es necesario modificar el esquema genético resultante de los procesos de selección natural a uno adaptado a las condiciones manejadas por el hombre, e implica detectar áreas geográficas similares a aquellas donde se originó la especie. En este estudio se analiza un modelo de áreas geográficas potenciales para la adaptación de Capsicum pubescens Ruiz & Pav. con el objetivo de detectar las condiciones de nicho ecológico apropiado, determinar zonas potenciales en México y describir las relaciones entre el medio ambiente y las características morfológicas del fruto. Se utilizó el algoritmo reciente de máxima entropía (MaxEnt) para modelar el nicho de C. pubescens dentro de una región de importancia en el centro de Veracruz, México. Se utilizó un total de 44 sitios de presencia y cuatro variables bioclimáticas para detectar nichos adecuados para la especie; así mismo, se realizó un análisis de regresión por mínimos cuadrados parciales (PLS) combinando los sitios de presencia, variables bioclimáticas y características morfológicas del fruto. Se construyó un mapa final de idoneidad identificando las áreas adecuadas para el crecimiento de C. pubescens. Las contribuciones de las variables predictoras al modelo fueron preipitación anual (Bio12) 43.9 %, capa de potasio (K) 23 %, altitud (DEM) 22.3 % y temperatura media anual (Bio1) 10.7 %, con valor del área bajo la curva de 99.7 %. Los mínimos cuadrados parciales corroboraron la importancia de las covariables, que intervienen en la expresión de características morfológicas del fruto, ayudando a entender mejor las relaciones entre especies y el medio ambiente. Áreas aún no exploradas arrojaron probabilidades de ocurrencia mayores a 90 %, principalmente en las zonas montañosas de Chihuahua, Tamaulipas, Nuevo León y la Sierra de Santa Martha al sur del estado de Veracruz. Se identificó un grupo de accesiones sobresalientes que podrían servir como base para iniciar un programa de mejoramiento genético en esta especie

Consumo de inflorescencia de maguey Agave sp. (Aspargales: Aspargaceae) por la ardilla de Peters Parasciurus oculatus (Rodentia: Sciuridae) en la Reserva de la Biosfera Sierra Gorda de Guanajuato, México

Approximately 87.5% of flowering plant species are pollinated by animals, however, the magnitude of the impact on plant pollination by rodents, a group to which squirrels belong, has been underestimated due to the lack of information. For the first time, we documented the consumption of inflorescences, nectar or pollen of maguey (Agave sp.) By the Peters squirrel (Parasciurus oculatus). It is necessary to continue monitoring the pollinators of the magueys, in order to determine the role that squirrels play in the pollination or predation processes of these plants.Aproximadamente el 87,5 % de las especies de plantas con flores son polinizadas por animales, sin embargo, la magnitud del impacto en la polinización de plantas por parte de los roedores, grupo al que pertenecen las ardillas, ha sido subestimada por la falta de información. Documentamos por primera ocasión consumo de las inflorescencias, néctar o polen de maguey (Agave sp.) por la ardilla de Peters (Parasciurus oculatus). Es necesario continuar el monitoreo de los polinizadores de los magueyes, para determinar el papel que juegan las ardillas en los procesos de polinización o depredación de estas plantas

Identificación genética de bacterias ácido lácticas nativas en leche cruda de vaca y queso Poro artesanal

El sabor y aroma de los quesos se debe a la diversidad de compuestos producidos por los microorganismos, que actúan durante el cuajado de la leche y maduración de los quesos. El objetivo aquí fue, identificar bacterias ácido lácticas en leche cruda de vaca y el queso Poro artesanal que se elabora en Tabasco, México. El aislamiento de las bacterias lácticas (BAL) se realizó sobre agar MRS, LBS y M17. Las cepas aisladas fueron caracterizadas por morfología, tinción de Gram, pruebas bioquímicas y crecimiento a diferentes concentraciones de cloruro de sodio (NaCl) y pH. La identificación genética inició con la extracción del ADN, amplificación del gen ARN ribosomal 16S con cebadores universales para bacterias. Las amplificaciones resultantes fueron secuenciadas en un laboratorio externo. Se identificaron 31 BAL, donde se observó Lactobacillus rhamnosus (38,71%), Lactobacillus fermentum (29,03%), Lactobacillus plantarum (6,45%) en muestras de leche y queso. También se identificó Enterococcus durans (6,45%) en leche y Lactobacillus farciminis (3,23%) en queso Poro. Todas reportadas por sus características biotecnológicas, tal como cultivos iniciadores. Estos resultados serán la base para formular y estabilizar un cultivo iniciador, que pueda ser utilizado en la elaboración del queso Poro con leche pasteurizada

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Measurements of the Higgs boson production cross section and couplings in the W boson pair decay channel in proton-proton collisions at s\sqrt{s} = 13 TeV

A preprint version of the article is available at arXiv:2206.09466v2 [hep-ex], https://arxiv.org/abs/2206.09466v2 . Comments: Replaced with the published version. Added the journal reference and the DOI. All the figures and tables can be found at httpS://cms-results.web.cern.ch/cms-results/public-results/publications/HIG-20-013 (CMS Public Pages). Report number: CMS-HIG-20-013, CERN-EP-2022-120.Production cross sections of the standard model Higgs boson decaying to a pair of W bosons are measured in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis targets Higgs bosons produced via gluon fusion, vector boson fusion, and in association with a W or Z boson. Candidate events are required to have at least two charged leptons and moderate missing transverse momentum, targeting events with at least one leptonically decaying W boson originating from the Higgs boson. Results are presented in the form of inclusive and differential cross sections in the simplified template cross section framework, as well as couplings of the Higgs boson to vector bosons and fermions. The data set collected by the CMS detector during 2016-2018 is used, corresponding to an integrated luminosity of 138 fb^−1. The signal strength modifier μ, defined as the ratio of the observed production rate in a given decay channel to the standard model expectation, is measured to be μ = 0.95 +0.10−0.09. All results are found to be compatible with the standard model within the uncertainties.SCOAP3

Search for new Higgs bosons via same-sign top quark pair production in association with a jet in proton-proton collisions at √s = 13 TeV

Data availability: Release and preservation of data used by the CMS Collaboration as the basis for publications is guided by the CMS policy as stated in “CMS data preservation, re-use and open access policy” available online at: https://cms-docdb.cern.ch/cgi-bin/PublicDocDB/RetrieveFile?docid=6032&filename=CMSDataPolicyV1.2.pdf&version=2 .A preprint of this article is available online at arXiv:2311.03261v2 [hep-ex] https://arxiv.org/abs/2311.03261v2 . Comments: Replaced with the published version. Added the journal reference and the DOI. All the figures and tables can be found at https://cms-results.web.cern.ch/cms-results/public-results/publications/TOP-22-010 (CMS Public Pages)A search is presented for new Higgs bosons in proton-proton (pp) collision events in which a same-sign top quark pair is produced in association with a jet, via the pp → tH/A → tt¯c and pp → tH/A → tt¯u processes. Here, H and A represent the extra scalar and pseudoscalar boson, respectively, of the second Higgs doublet in the generalized two-Higgs-doublet model (g2HDM). The search is based on pp collision data collected at a center-of-mass energy of 13 TeV with the CMS detector at the LHC, corresponding to an integrated luminosity of 138 fb−1. Final states with a same-sign lepton pair in association with jets and missing transverse momentum are considered. New Higgs bosons in the 200-1000 GeV mass range and new Yukawa couplings between 0.1 and 1.0 are targeted in the search, for scenarios in which either H or A appear alone, or in which they coexist and interfere. No significant excess above the standard model prediction is observed. Exclusion limits are derived in the context of the g2HDM.SCOAP3

Search for direct production of GeV-scale resonances decaying to a pair of muons in proton-proton collisions at s\sqrt{s} = 13 TeV

A preprint version of the article is available at arXiv:2309.16003v2 [hep-ex], https://arxiv.org/abs/2309.16003v2 . Comments: Replaced with the published version. Added the journal reference and the DOI. All the figures and tables, including additional supplementary figures, can be found at https://cms-results.web.cern.ch/cms-results/public-results/publications/EXO-21-005 (CMS Public Pages). Report number: CMS-EXO-21-005, CERN-EP-2023-165.A search for direct production of low-mass dimuon resonances is performed using s√ = 13 TeV proton-proton collision data collected by the CMS experiment during the 2017-2018 operation of the CERN LHC with an integrated luminosity of 96.6 fb−1. The search exploits a dedicated high-rate trigger stream that records events with two muons with transverse momenta as low as 3 GeV but does not include the full event information. The search is performed by looking for narrow peaks in the dimuon mass spectrum in the ranges of 1.1-2.6 GeV and 4.2-7.9 GeV. No significant excess of events above the expectation from the standard model background is observed. Model-independent limits on production rates of dimuon resonances within the experimental fiducial acceptance are set. Competitive or world's best limits are set at 90% confidence level for a minimal dark photon model and for a scenario with two Higgs doublets and an extra complex scalar singlet (2HDM+S). Values of the squared kinetic mixing coefficient ε2 in the dark photon model above 10−6 are excluded over most of the mass range of the search. In the 2HDM+S, values of the mixing angle sin(θH) above 0.08 are excluded over most of the mass range of the search with a fixed ratio of the Higgs doublets vacuum expectation tanβ = 0.5.SCOAP3
