New ALICE detectors for Run 3 and 4 at the CERN LHC
2020
Abstract Run 3 at the CERN LHC is scheduled to start in March 2021. In preparation for this new data taking period the ALICE experiment is making major modifications to its subsystems and is introducing three new detectors: the new Inner Tracking System, the Muon Forward Tracker, and the Fast Interaction Trigger. The new detectors will enhance tracking, especially at low transverse momenta, improve vertexing, provide the required triggering, fast timing, luminosity, and forward multiplicity functionality. For instance, it will be possible to measure beauty from displaced J/ ψ vertices down to transverse momenta p T ∼ 0 and improve precision for the ψ (2S) measurements. The upgraded ALICE wi…
Análisis molecular de la valoración del intervalo de tiempo óptimo entre la administración de acetato de triptorelina y la punción folicular en los t…
2023
Los fármacos análogos de la GnRH y la hCG han demostrado ser igualmente eficaces en la activación de la cascada de intermediarios de la maduración final ovocitaria que ocurre tras el estímulo ovulatorio. Sin embargo, su mecanismo de acción y por tanto los perfiles hormonales hallados tras el estímulo de los dos fármacos son muy diferentes. El tiempo más adecuado para programar la recolección ovocitaria tras la administración de acetato de triptorelina podría no ser 36 horas como ampliamente se ha pautado en los tratamientos de FIV con hCG. Este intervalo de tiempo es sumamente importante para obtener la mayor proporción posible de ovocitos MII porque procesos como el inicio de la luteinizac…
The Performance of Belle II High Level Trigger in the First Physics Run
2020
The Belle II experiment is a new generation B-factory experiment at KEK in Japan aiming at the search for New Physics in a huge sample of B-meson decays. The commissioning of the accelerator and the detector for the first physics run has started from March this year. The Belle II High Level Trigger (HLT) is fully working in the beam run. The HLT is now operated with 1600 cores clusterized in 5 units, which is 1/4 of the full configuration. The software trigger is performed using the same offline reconstruction code, and events are classified into a set of physics categories. Only the events in the categories of interest are finally sent out to the storage. Live data quality monitoring is also…
Interleukin-22 and interleukin-22-producing NKp44+ natural killer cells in subclinical gut inflammation in ankylosing spondylitis
2012
Objective The intestinal inflammation observed in patients with ankylosing spondylitis (AS) is characterized by an overexpression of interleukin-23 (IL-23). IL-23 is known to regulate IL-22 production through lamina propria NKp44+ natural killer (NK) cells, which are thought to be involved in protective mucosal mechanisms. This study was undertaken to evaluate the frequency of NKp44+ NK cells and the expression of IL-22 in the ileum of AS patients. Methods Tissue NKp44+ NK cells, NKp46+ NK cells, and IL-22–producing cells were analyzed by flow cytometry. Quantitative gene expression analysis of IL-22, IL-23, IL-17, STAT-3, and mucin 1 (MUC-1) was performed by reverse transcriptase–polymeras…
Inducing efficient conditional cooperation patterns in public goods games, an experimental investigation
2010
This study analyses the behavior in a repeated public goods game when subjects know about the possibility of existence of strict conditional cooperators. We employed a baseline treatment and a threat treatment in which subjects are informed about the possibility of being in a group together with automata playing a grim trigger strategy. We conjecture the resulting game allows for almost fully efficient outcomes. Contributions in the threat treatment increase by 40% before a surprise restart, and by 50% after the surprise restart. In line with the grim trigger strategy subjects contribute either all or nothing in the threat treatment.
Types, triggers and treatment strategies of psoriasis
2013
Psoriasis is a common chronic, immune mediated, inflammatory disease,characterized by periods of exacerbation and remission. Patients with psoriasis have asignificantly impaired quality of life; the disease is associated with substantial burden interms of disability or psychosocial stigmatization. Moreover, in a percentage of patientsthat varies between 5% and 42%, depending on the population studied, psoriatic arthritismay occur.Psoriasis is found worldwide but the prevalence varies among different ethnicgroups. It has a strong genetic component but environmental factors such as ß-haemolyticstreptococcal infection, HIV, stress, and drugs, including ß blockers, antimalarials andlithium can …

Inhibition of the NKp30 activating receptor by pp65 of human cytomegalovirus.
2005
Human cytomegalovirus, a chief pathogen in immunocompromised people, can persist in a healthy immunocompetent host throughout life without being eliminated by the immune system. Here we show that pp65, the main tegument protein of human cytomegalovirus, inhibited natural killer cell cytotoxicity by an interaction with the activating receptor NKp30. This interaction was direct and specific, leading to dissociation of the linked CD3zeta from NKp30 and, consequently, to reduced killing. Thus, pp65 is a ligand for the NKp30 receptor and demonstrates a unique mechanism by which an intracellular viral protein causes general suppression of natural killer cell cytotoxicity by specific interaction w…

Localization of Muscle Edema and Changes on Muscle Contractility After Dry Needling of Latent Trigger Points in the Gastrocnemius Muscle.
2019
Background Myofascial trigger points (TrPs) are hyperirritable spots within taut bands of skeletal muscles that elicit local and referred pain when stimulated. Among the variety of techniques used for treating TrPs, dry needling (DN) is the most commonly applied intervention. The physiological mechanisms underlying the effects of DN remain to be elucidated. Objective To examine changes in skeletal muscle after DN in the area where the TrP is located. Methods We measured in vivo changes that occur in human skeletal muscle one hour after DN over a TrP with magnetic resonance imaging (MRI) and tensiomyography. The study included 18 asymptomatic subjects with a latent TrP in one medial gastrocn…
