2014

Spectral imaging system for money counterfeit detection

2019

A prototype with three different wavelength lasers (448nm, 532nm and 659nm) for money counterfeit illumination, analyzation and detection using RGB crosstalk correction and comparing spectral image ration for different banknote elements will be presented.

CeSOX: An experimental test of the sterile neutrino hypothesis with Borexino

2017

International audience; The third phase of the Borexino experiment that’s referred to as SOX is devoted to test the hypothesis of the existence of one (or more) sterile neutrinos at a short baseline (~5–10m). The experimental measurement will be made with artificial sources namely with a 144Ce–144Pr antineutrino source at the first stage (CeSOX) and possibly with a 51Cr neutrino source at the second one. The fixed 144Ce–144Pr sample will be placed beneath the detector in a special pit and the initial activity will be about 100 – 150 kCi. The start of data taking is scheduled for April 2018. The article gives a short description of the preparation for the first stage and shows the expected s…

Small-$x$ Physics in the Dipole Picture at NLO Accuracy

2018

International audience; We review recent progress in NLO calculations for dilute-dense processes in the CGC picture. In particular, we focus here on recent steps in understanding high energy renormalization group evolution (BK/JIMWLK), the total DIS cross section at small x and forward particle production in proton-nucleus collisions at next-to-leading order.

Molecular Mechanisms of the Crosstalk Between Mitochondria and NADPH Oxidase Through Reactive Oxygen Species—Studies in White Blood Cells and in Anim…

2014

Aims: Oxidative stress is involved in the development of cardiovascular disease. There is a growing body of evidence for a crosstalk between different enzymatic sources of oxidative stress. With the present study, we sought to determine the underlying crosstalk mechanisms, the role of the mitochondrial permeability transition pore (mPTP), and its link to endothelial dysfunction. Results: NADPH oxidase (Nox) activation (oxidative burst and translocation of cytosolic Nox subunits) was observed in response to mitochondrial reactive oxygen species (mtROS) formation in human leukocytes. In vitro, mtROS-induced Nox activation was prevented by inhibitors of the mPTP, protein kinase C, tyrosine kin…

Presynaptic regulation of the electrically evoked release of endogenous dopamine from the isolated neurointermediate lobe or isolated neural lobe of …

1988

Isolated neurointermediate lobes (NILs) or isolated neural lobes (NLs) of the rat pituitary gland were incubated in Krebs-HEPES solution which contained pargyline and the dopamine uptake inhibitor GBR 12921. The release of endogenous dopamine was determined by HPLC with electrochemical detection. Electrical stimulation of the pituitary stalk induced a frequency-dependent release of dopamine. The release of dopamine from the combined NIL evoked by stimulation at 15 Hz was increased by 130% in the presence of the dopamine D2 receptor antagonist, (-)-sulpiride; the (+)-enantiomer of sulpiride had virtually no effect. When the stimulation frequency was 3 Hz (-)-sulpiride caused an increase in d…

MR IMAGING AND HORMONAL FINDINGS IN PATIENTS WITH IDIOPATHIC GROWTH HORMONU DEFICIENCY

1993

Until the introduction of MR imaging in neuroradiological diagnostic, diagnosis of the ecotopic posterior pituitary lobe, first described by the pathologist Priesel in 1920, was rare. Recently it has increasingly been diagnosed by MR in patients whose anamnesis showed birth trauma. We performed MR of the hypothalamic-pituitary region in 17 patients with idiopathic growth hormone deficiency. 8 patients had additional deficiencies of the anterior pituitary lobe whereas the function of the posterior lobe of the hypophysis was normal in all patients. Indications of birth trauma were present in only 2 patients. The cause of anterior lobe insufficiency was determined by MR in 8 patients with panh…

The Role of Autophagy and Apoptosis During Embryo Development

2015

Programmed cell death (PCD) and cell survival are two sides of the same coin. Autopha‐ gy and apoptosis are crucial processes during embryo development of Invertebrates and Vertebrates organisms, as they are necessary for the formation of a new organism, start‐ ing from a fertilized egg. Fertilization triggers cell remodeling from each gamete to a toti‐ potent zygote. During embryogenesis, the cells undergo various processes, thus allowing the transformation of the embryo into an adult organism. In particular, cells require the appropriate tools to suddenly modify their morphology and protein content in order to respond to intrinsic and external stimuli. Autophagy and apoptosis are involved…

Stalking: definizione del costrutto, aspetti fenomenologici, comportamenti associati.

2011

Objectives: Scientific literature on stalking behaviors is not sufficiently uniform and shows no clear definition of the theorical construct of stalking. In order to respond to current scientific criteria for defining a psychological and behavioral construct, the definition of "stalking" should be exhaustive and specific at the same time. There must be also a positive consensus by scholars on a definition of a construct, for that definition becoming operationalized and therefore profitably appliable in theory and research. Methods: Exploring the theoretical definitions of stalking that are privileged in current literature, and reviewing the different behavioral markers suggested for identif…

Gadamer y el problema hermenéutico de la interpretación psicoanalítica

2020

Existe una posición privilegiada para analizar la relación posible entre la filosofía y el psicoanálisis, y esta es a través de la hermenéutica. No solo Ricoeur, multitud de autores, a uno y otro lado de la disputa, han expresado sus posturas acerca de qué comparten y qué distinguen al psicoanálisis y a la hermenéutica filosófica, que quiere servir de vehículo para comprender la esencia interpretante del ser humano. Debido a ello, autores como Heidegger y Gadamer se han visto llamados a expresar sus posiciones acerca del saber del inconsciente, para evaluar el modo de poner en contacto la esencia del psicoanálisis como talking cure y la referencia interna de la filosofía como diálogo. Con t…
