Caracterización de la geografía de las muertes por cáncer en Mexico

We identified municipalities in Mexico with cancer incidence above normal behavior to identify whether age, nutrition or endogamy are factors that increase the risk of cancer. The objective was to compare the incidence distribution with hospital capacities and to estimate the probability of preventing cancer incidence, the municipal distribution of cancer deaths, and weighted by the incidence of cancer deaths per 1,000 inhabitants, identifying municipalities with similar behavior through independent groupings. Five groups of Mexico municipalities varies from with very low incidence to very high incidence of cancer. Regions of Mexico with very high incidence of cancer are possibly due to a high family inbreeding and low food variety. There is an opportunity for active-ingredients from local plant genetic resources to delay the incidence of cancer

Proyectos de conservación y tolerancia de mamíferos silvestres en Oaxaca, Mexico

In order to implement strategies for conservation and tolerance of wild mammals in a region of mesophyll forest in Oaxaca, México, monitoring was carried out by using trap cameras to analyze the diversity, abundance and activity patterns of the species, also applying surveys to the inhabitants to analyze the social perspective in reference to the presence of wild fauna. Eleven species of medium and large mammals were registered, three with greater abundance, two with daytime activity and one with nighttime. The residents do not know all the species present; however, they consider that it is important to conserve them through conservation projects and strategies, particularly those identified in some category of risk

Evaluación de un dilutor elaborado con jugo de opuntia sp., en la crioconservación de semen de bovino

A dilutor was elaborated with prickly pear (Opuntia sp.) juice to dilute and cryopreserve bovine semen, and to evaluate it, was compared with two commercial dilutors: Triladyl® and BoviPRO®. Three Holstein adult bulls were used, from which semen was collected with an artificial vagina. The ejaculates were mixed to form a “pool”, where bulk mobility, sperm concentration, morphology and percentage of live spermatozoa were evaluated from fresh semen. Later, it was divided into three fractions, which were diluted with the different extensors for their freezing in nitrogen vapors. The variables evaluated were percentage of live spermatozoa and integrity of the membrane, which were analyzed through the GLM procedure. A difference was found (p0.05) in the variable of live spermatozoa for the treatment with prickly pear juice (19.61.18%), compared to the treatments with Triladyl® (46.41.08%) and BoviPRO® (46.61.18%). For the variable membrane integrity, a difference was obtained from the prickly pear juice (17.260.98%) with regards to BoviPRO® (46.681.15%) and Triladyl® (38.281.34%). It is concluded that the prickly pear juice extensor is a good option for the cryopreservation of bovine semen; however, it is necessary to continue studying its qualities to improve the characteristics of the cryopreserved semen

Potencial productivo y rentabilidad del cultivo de fresa (fragaria fragariaxananassa (weston) duchesne) en salinas, San Luis Potosí, Mexico

The strawberry crop is known by its quick investment, intensive use of labor, and high consumption demand; thus, the productive potential and profitability of the strawberry crop (Fragaria fragariaananassa (Weston) Duchesne) was evaluated, in Salinas, San Luis Potosí, with the objective of diversifying economic options. The study was performed in the alternative crops module of Ejido Diego Martín, with an experiment with 12,000 strawberry plants, Albión cultivar, established with naked roots on 20 ridges, 60 m long and 1.4 m wide; 10 were padded with silver/black plastic film and the rest with white/black. The strawberry production per furrow and harvest was recorded during the April-November period, in 2014. The extrapolated yields were equivalent to 32,672 kg ha1, with an investment of $325,290 ha1 and total income of$522,755. The profitability analysis indicated that the yields recorded were similar to the national mean, and the benefit/cost relationship was 1.6, with an internal return rate of 18%

Search for invisible Higgs boson decays in vector boson fusion at √s = 13 TeV with the ATLAS detector

We report a search for Higgs bosons that are produced via vector boson fusion and subsequently decay into invisible particles. The experimental signature is an energetic jet pair with invariant mass of O(1) TeV and O(100) GeV missing transverse momentum. The analysis uses 36.1 fb−1 of pp collision data at √s=13 TeV recorded by the ATLAS detector at the LHC. In the signal region the 2252 observed events are consistent with the background estimation. Assuming a 125 GeV scalar particle with Standard Model cross sections, the upper limit on the branching fraction of the Higgs boson decay into invisible particles is 0.37 at 95% confidence level where 0.28 was expected. This limit is interpreted in Higgs portal models to set bounds on the wimp–nucleon scattering cross section. We also consider invisible decays of additional scalar bosons with masses up to 3 TeV for which the upper limits on the cross section times branching fraction are in the range of 0.3–1.7 pb

Observation of photon-induced W⁺W⁻ production in pp collisions at √s=13 TeV using the ATLAS detector

This letter reports the observation of photon-induced production of W-boson pairs, γγ→ WW. The analysis uses 139 fb-1 of LHC proton-proton collision data taken at √s=13 TeV recorded by the ATLAS experiment during the years 2015-2018. The measurement is performed selecting one electron and one muon, corresponding to the decay of the diboson system as WW→e±νμ∓ν final state. The background-only hypothesis is rejected with a significance of well above 5 standard deviations consistent with the expectation from Monte Carlo simulation. A cross section for the γγ→ WW process of 3.13±0.31(stat.)±0.28(syst.) fb is measured in a fiducial volume close to the acceptance of the detector, by requiring an electron and a muon of opposite signs with large dilepton transverse momentum and exactly zero additional charged particles. This is found to be in agreement with the Standard Model prediction

Measurement of the total cross section and ρ -parameter from elastic scattering in pp collisions at √s=13 TeV with the ATLAS detector

In a special run of the LHC with β⋆=2.5 km, proton–proton elastic-scattering events were recorded at s√=13 TeV with an integrated luminosity of 340 μb−1 using the ALFA subdetector of ATLAS in 2016. The elastic cross section was measured differentially in the Mandelstam t variable in the range from −t=2.5⋅10−4 GeV2 to −t=0.46 GeV2 using 6.9 million elastic-scattering candidates. This paper presents measurements of the total cross section σtot, parameters of the nuclear slope, and the ρ-parameter defined as the ratio of the real part to the imaginary part of the elastic-scattering amplitude in the limit t→0. These parameters are determined from a fit to the differential elastic cross section using the optical theorem and different parameterizations of the t-dependence. The results for σtot and ρ are σtot(pp→X)=104.7±1.1 mb ,ρ=0.098±0.011. The uncertainty in σtot is dominated by the luminosity measurement, and in ρ by imperfect knowledge of the detector alignment and by modelling of the nuclear amplitude.publishedVersio

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.

Searches for lepton-flavour-violating decays of the Higgs boson in s=13\sqrt{s}=13 TeV pp\mathit{pp} collisions with the ATLAS detector

This Letter presents direct searches for lepton flavour violation in Higgs boson decays, H → eτ and H → μτ , performed with the ATLAS detector at the LHC. The searches are based on a data sample of proton–proton collisions at a centre-of-mass energy √s = 13 TeV, corresponding to an integrated luminosity of 36.1 fb−1. No significant excess is observed above the expected background from Standard Model processes. The observed (median expected) 95% confidence-level upper limits on the leptonflavour-violating branching ratios are 0.47% (0.34+0.13−0.10%) and 0.28% (0.37+0.14−0.10%) for H → eτ and H → μτ , respectively.publishedVersio
