Tricks and Tracks in the Identification and Quantification of Endocannabinoids
2013
Abstract The endocannabinoid system serves pivotal roles in a diverse range of physiological and pathophysiological states, including behavior, pain, schizophrenia, obesity, Alzheimer disease, multiple sclerosis and cardiovascular disease. A number of endocannabinoids (eCBs) and their receptors have been characterised and identified in a plethora of biological matrices. The eCBs include N-arachidonoyl ethanolamine (anandamide), 2-arachidonoyl glycerol, 2-arachidonoyl glyceryl ether (noladin ether), O-arachidonoyl ethanolamine (virodhamine) and N-arachidonoyl dopamine. Advanced targeted mass spectrometry methods, particularly the selected reaction monitoring, has facilitated sensitive quanti…
Resveratrol in Experimental Models and Humans
2018
Abstract The search for natural compounds with beneficial activity for health has been one of the great challenges since men are aware of their survival. Many elixirs and ointments have been tested as the possible treatment or remedy for diseases or even death. In traditional medicine, compounds with biological activities have been used in humans. Among them, resveratrol (RSV) is, currently, one of the most studied natural compounds by modern science. To study this polyphenol we have a series of very useful tools that allow us to investigate from molecular targets, to signaling pathways in which it is involved, as well as effects on pathologies and even health and longevity. In this chapter…
Functionalization of nanoparticles in specific targeting and mechanism release
2017
The development of various nanotechnologies have provided a new field of research, which allows the manipulation of molecular components of matter and covers a vast array of nanodevices. The “smart” multifunctional nanostructures should work as customizable, targeted drug-delivery vehicles capable of carrying large doses of therapeutic agents into malignant cells. Some nanomedical approaches are based on the use of functionalized nanoparticles (NPs), not only to reduce toxicity and side effects of drugs but, also in potential the biological barriers crossing on, such as: the blood–brain barrier, different cellular compartments, including the nucleus. Currently, many materials are used for n…
Measurement of the spin-dependent structure function g1(x) of the deuteron
1993
We report on the first measurement of the spin-dependent structure function g1d of the deuteron in the deep inelastic scattering of polarised muons off polarised deuterons, in the kinematical range 0.006<x<0.6, 1 GeV2<Q2<30 GeV2. The first moment, Γ1d=sh{phonetic}01 g1d dx=0.023±0.020 (stat.) ± 0.015 (syst.), is smaller than the prediction of the Ellis-Jaffe sum rules. Using earlier measurements of g1p, we infer the first moment of the spin-dependent neutron structure function g1n. The difference Γ1p-Γ1n=0.20 ±0.05 (stat.) ± 0.04 (syst.) agrees with the prediction of the Bjorken sum rule, Γ1p-Γ1n=0.191 ±0.002.
Management of metabolic adverse events of targeted therapies and immune checkpoint inhibitors in cancer patients: an Associazione Italiana Oncologia …
2020
The growing insights in the next-generation immunotherapy and the state-of-the-art advancement in targeted-agents significantly improved clinical outcome of cancer patients by pointing towards a unexplored Achilles' heel. Novel toxicity profiles have been uncovered, representing unmet medical needs. Thus, a panel of expert provide comprehensive pharmacological and clinical evidence, to provide a patient-tailored approach to metabolic adverse events associated with novel anti-cancer treatments. Prompted by the need of a multidisciplinary cooperation, a working group of Associazione Italiana Oncologia Medica (AIOM), Associazione Medici Diabetologi (AMD) and Societa Italiana Farmacologia (SIF)…
¿Podemos favorecer el proceso de aprendizaje y la inclusión social y académica en la universidad de los estudiantes con más dificultades? Propuesta d…
2018
Durante el primer curso universitario, los estudiantes deben hacer frente a nuevas exigencias académicas, (evaluación, metodologías docentes...), con el fin de superar ese primer curso, al tiempo de integrarse socialmente en un contexto, la universidad, nuevo para ellos. Para ello, deben adquirir o reforzar distintas habilidades. La literatura científica ha evidenciado la relación entre estas variables con el rendimiento académico y el ajuste al primer año de universidad: actitudes ante el aprendizaje (Gargallo et al, 2007-A-), estrategias de aprendizaje (Gargallo et al., 2009), estrés académico (Rayle y Chung, 2007; Robotham y Julian 2006), autoeficacia académica (Palacio et al., 2012; Sal…
A novel rationale for targeting FXI: Insights from the hemostatic miRNA targetome for emerging anticoagulant strategies
2018
Abstract The treatment and prevention of thrombosis is currently under a period of rapid change with the replacement of traditional anticoagulant vitamin K antagonists, which impair the biosynthesis of a wide range of blood coagulation factors, with direct oral anticoagulants (DOACs), which specifically target factors FXa or FIIa. Nevertheless therapeutic targeting of blood coagulation is an inherently difficult task as it interferes with the delicate balance of pro- and anticoagulant activities. Although anticoagulants are employed in millions of thrombophilic patients worldwide each year, for a growing population with comorbidities who exhibit an increased risk of bleeding with DOAC treat…
Measurement of the SMC muon beam polarisation using the asymmetry in the elastic scattering off polarised electrons
2000
A muon beam polarimeter was built for the SMC experiment at the CERN SPS, for beam energies of 100 and 190 GeV. The beam polarisation is determined from the asymmetry in the elastic scattering off the polarised electrons of a ferromagnetic target whose magnetisation is periodically reversed. At muon energies of 100 and 190 GeV the measured polarisation is P-mu = -0.80 +/- 0.03 (stat.) +/- 0.02 (syst.) and P-mu = - 0.797 +/- 0.011 (stat.) +/- 0.012 (syst.), respectively. These results agree with measurements of the beam polarisation using a shape analysis of the decay positron energy spectrum. (C) 2000 Elsevier Science B.V. All rights reserved.

Preservation of the soft protein corona in distinct flow allows identification of weakly bound proteins.
2018
Abstract Nanocarriers that are used for targeted drug delivery come in contact with biological liquids and subsequently proteins will adsorb to the nanocarriers’ surface to form the so called ‘protein corona’. The protein corona defines the biological identity and determines the biological response towards the nanocarriers in the body. To make nanomedicine safe and reliable it is required to get a better insight into this protein corona and, therefore, the adsorbed proteins have to be characterized. Currently, centrifugation is the common method to isolate the protein corona for further investigations. However, with this method it is only possible to investigate the strongly bound proteins,…
