Immunohistochemical comparative study of the odontogenic keratocysts and other odontogenic lesions
2009
Objectives: The present study was undertaken to compare the pattern of expression of EGFR, cyclin D1, Ki-67, p-53 and carcinoembryonic antigen (CEA) in the epithelial lining of odontogenic keratocysts, dentigerous cysts, radicular cysts and ameloblastomas. Methods: four micrometers, formalin-fixed, paraffin-embedded tissue sections from 11 odontogenic keratocysts, 10 dentigerous cysts, 10 radicular cysts and 10 ameloblastomas were immunohistochemically studied. Results: There were statistically significant differences between cyclin D1 expression in odontogenic keratocysts and radicular cysts (p= 0.001) and ameloblastomas (p= 0.04). The differences in CEA expression between the four studied…
Cuerpos moldeables y vidas modulables: La invención del estado holísticamente saludable como bienestar (integral)
2020
The article argues ?from the Deleuzian concepts of society of control, moulding and modulation and the Rosean theory on the economization and medicalization of life? that the expansion of the concept of health in terms of integral and subjective well-being is the effect of a socio-historical shift in the way we relate to this signifier, and therefore to our bodies and ourselves. We use this interpretative network to analyze the effects that the biopsychosocial health paradigm has had in the context of aesthetic surgery and fitness practice. As a result, we see that the expansion of the concept of health has extended the domain of medicine into the spheres of personal care and physical appea…
IL-6 trans-Signaling
2004
The molecular consequence of the fever response has been illuminated by a recent study showing that a temperature shift to 40 degrees C resulted in increased leukocyte adhesion to tissue sections, which was mediated by L-selectin activation in lymphocytes. This L-selectin activation during heat responses was dependent on IL-6 trans-signaling via the soluble IL-6R.

Constraining the spin-dependent WIMP-nucleon cross sections with XENON1T
2019
We report the first experimental results on spin-dependent elastic weakly interacting massive particle (WIMP) nucleon scattering from the XENON1T dark matter search experiment. The analysis uses the full ton year exposure of XENON1T to constrain the spin-dependent proton-only and neutron-only cases. No significant signal excess is observed, and a profile likelihood ratio analysis is used to set exclusion limits on the WIMP-nucleon interactions. This includes the most stringent constraint to date on the WIMP-neutron cross section, with a minimum of 6.3 × 10−42 cm2 at 30 GeV/c2 and 90% confidence level. The results are compared with those from collider searches and used to exclude new paramet…
Thermal neutron capture cross sections of tellurium isotopes
2003
New values for thermal neutron capture cross sections of the tellurium isotopes 122Te, 124Te, 125Te, 126Te, 128Te, and 130Te are reported. These values are based on a combination of newly determined partial g-ray cross sections obtained from experiments on targets contained natural Te and gamma intensities per capture of individual Te isotopes. Isomeric ratios for the thermal neutron capture on the even tellurium isotopes are also given.
Las secciones de crédito en el ordenamiento jurídico español
1999
A credit section is an economic and functional demarcation within a co-operative that, without having an independent juridical personality out of the co-operative it belongs, operates as a financial entity, limiting its active and passive operations to the co-operative and its members. The credit sections are recognized by all the autonomical co-operative laws and they have been especially regulated in Catalonia and the Valencian Community. The regulation contained in the Ley de Cooperativas 27/1999 (Law of Co-operatives 27/1999) clearly restricts the subjective and objective field of activity of the credit sections, but it does not limit the action sphere of co-operatives governed by the a…
Neutron capture cross section measurements for nuclear astrophyisics at CERN n_TOF
2005
A series of neutron capture cross section measurements of interest to nuclear astrophysics have been recently performed at n_TOF, the neutron spallation source operating at CERN. The low repetition frequency of the proton beam driver, the extremely high instantaneous neutron flux, and the low background conditions in the experimental area are optimal for capture cross section measurements on low-mass or radioactive samples. An overview of the measurements performed during the two experimental campaigns in 2002 and 2003 is presented with special emphasis on the measurement of the capture cross sections of the Os isotopes relevant for the cosmochronology based on the Re/Os clock. http://www.s…
Measurement of the muon neutrino inclusive charged-current cross section in the energy range of 1–3 GeV with the T2K INGRID detector
2016
International audience; We report a measurement of the $\nu_{\mu}$-nucleus inclusive charged current cross section (=$\sigma^{cc}$) on iron using data from exposed to the J-PARC neutrino beam. The detector consists of 14 modules in total, which are spread over a range of off-axis angles from 0$^\circ$ to 1.1$^\circ$. The variation in the neutrino energy spectrum as a function of the off-axis angle, combined with event topology information, is used to calculate this cross section as a function of neutrino energy. The cross section is measured to be $\sigma^{cc}(1.1\text{ GeV}) = 1.10 \pm 0.15$ $(10^{-38}\text{cm}^2/\text{nucleon})$, $\sigma^{cc}(2.0\text{ GeV}) = 2.07 \pm 0.27$ $(10^{-38}\te…
Prognostic Impact of Frozen Section Investigation and Extent of Proximal Safety Margin in Gastric Cancer Resection
2020
Background and aims Guidelines propose different extents of macroscopic proximal margin for gastric cancer and frozen margin investigation in selected cases, but data is lacking. This study was to evaluate the necessary extent of macroscopic proximal margin, accuracy of frozen margin investigation, and prognostic impact of tumor-free proximal margin length in pT2-pT4 gastric cancer. Study design Proximal and distal frozen margins were routinely investigated intraoperatively in all pT2-pT4 gastric cancers resected between 2011 and 2017. Macroscopic and microscopic proximal margin lengths were correlated. For R0-resections, survival analysis was performed for distal gastrectomy (DG) with micr…
