Stability and disassembly properties of human naïve Hsp60 and bacterial GroEL chaperonins.
2015
Human Hsp60 chaperonin and its bacterial homolog GroEL, in association with the corresponding co-chaperonins Hsp10 and GroES, constitute important chaperone systems promoting the proper folding of several mitochondrial proteins. Hsp60 is also currently described as a ubiquitous molecule with multiple roles both in health conditions and in several diseases. Naïve Hsp60 bearing the mitochondrial import signal has been recently demonstrated to present different oligomeric organizations with respect to GroEL, suggesting new possible physiological functions. Here we present a combined investigation with circular dichroism and small-angle X-ray scattering of structure, self-organization, and sta…

Five insights from the Global Burden of Disease Study 2019
2020
The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 provides a rules-based synthesis of the available evidence on levels and trends in health outcomes, a diverse set of risk factors, and health system responses. GBD 2019 covered 204 countries and territories, as well as first administrative level disaggregations for 22 countries, from 1990 to 2019. Because GBD is highly standardised and comprehensive, spanning both fatal and non-fatal outcomes, and uses a mutually exclusive and collectively exhaustive list of hierarchical disease and injury causes, the study provides a powerful basis for detailed and broad insights on global health trends and emerging challenges. GBD …

Event-by-event picture for the medium-induced jet evolution
2016
We discuss the evolution of an energetic jet which propagates through a dense quark-gluon plasma and radiates gluons due to its interactions with the medium. Within perturbative QCD, this evolution can be described as a stochastic branching process, that we have managed to solve exactly. We present exact, analytic, results for the gluon spectrum (the average gluon distribution) and for the higher n-point functions, which describe correlations and fluctuations. Using these results, we construct the event-by-event picture of the gluon distribution produced via medium-induced gluon branching. In contrast to what happens in a usual QCD cascade in vacuum, the medium-induced branchings are quasi-…
Centrality dependence of inclusive J/ψ production in p-Pb collisions at √sNN = 5.02 TeV
2015
We present a measurement of inclusive J/ψ production in p-Pb collisions at √ sNN = 5.02 TeV as a function of the centrality of the collision, as estimated from the energy deposited in the Zero Degree Calorimeters. The measurement is performed with the ALICE detector down to zero transverse momentum, pT, in the backward (−4.46 < ycms < −2.96) and forward (2.03 < ycms < 3.53) rapidity intervals in the dimuon decay channel and in the mid-rapidity region (−1.37 < ycms < 0.43) in the dielectron decay channel. The backward and forward rapidity intervals correspond to the Pb-going and p-going direction, respectively. The pT-differential J/ψ production cross section at backward and forward rapidity…
Higgs-pair production via gluon fusion at NLO QCD in the Standard Model and Beyond
2021
La fı́sica de las partı́culas elementales está bien descrita por el Modelo Estándar (SM, por sus siglas en inglés.). La presencia de la interacción electrodébil prohı́be los términos cuadráticos con respecto a los campos, i.e. términos de masa, en el Lagrangiano del SM. La presencia de tales términos de masa requieren de la llamada ruptura espontánea de la simetrı́a, introduciendo un doblete electrodébil con un valor esperado de vacı́o no nulo. Como recordatorio, la ruptura espontánea de la simetrı́a genera un bosón escalar neutro, el renombrado bosón de Higgs. Aunque fue predicho en los años 60 por argumentos teóricos, en el 2012 los experimentos del Large Hadron Collider (LHC), ATLAS y CM…
Chronic Endometritis in Infertile Women: Impact of Untreated Disease, Plasma Cell Count and Antibiotic Therapy on IVF Outcome—A Systematic Review and…
2022
This systematic review and meta-analysis aims to evaluate the impact of chronic endometritis (CE) and its therapy on in vitro fertilization (IVF) outcome. Additionally, we aim to investigate whether various degrees of CE severity may exert a different effect on IVF outcome. Ongoing-pregnancy rate/live-birth-rate (OPR/LBR), clinical-pregnancy rate (CPR), and miscarriage rate (MR) were calculated. A total number of 4145 patients (from ten studies) were included. Women with CE had lower OPR/LBR (OR 1.97, p = 0.02) and CPR (OR 2.28, p = 0.002) compared to those without CE. CE cure increased OPR/LBR (OR 5.33, p < 0.0001) and CPR (OR 3.64, p = 0.0001). IVF outcome was comparable between women …
Le cadre de sante entre logiques d'utilité économique et logiques de soins hospitaliers
2010
The public hospital first line manager has to organize the activity of his care unit on the basis of arbitrations between two systems of logic that come more and more frequently in conflict: - The market logic / the public hospital logic - The care process logic / the patient's path logic - The function logic / the professional logic - The managerial logic / the logic "bureaucratic"
O projeto Mujeres Maestras del Perú. Estudo de caso sobre identidades de ensino
2018
El proyecto «Mujeres Maestras de Perú» nos acerca a las opiniones de veintiun maestras peruanas. Las que trabajan en entornos menos favorecidos e insisten en su precocidad vocacional. Las maestras nos hablan de dicho factor vocacional como de algo que ya aparece en su infancia en tanto que deseo explícito de dedicarse a la docencia. Nuestra investigación parte de un enfoque cualitativo, mediante un estudio de caso al que incorporamos elementos de rango artístico (Investigación basada en las artes). Utilizamos grabaciones audiovisuales como instrumento de recogida de datos. Desde la educación artística, visibilizamos las identidades del colectivo docente como homenaje y reivindicación profes…
