Paraneoplastic Limbic Encephalitis in a Male with Squamous Cell Carcinoma of the Lung
Tamara Sauri,Àngel Izquierdo,LLuis Ramió-Torrentà,Àngel Sanchez-Montañez,Joaquim Bosch-Barrera,Rut Porta 대한신경과학회 2015 Journal of Clinical Neurology Vol.11 No.1
Background Paraneoplastic limbic encephalitis (PLE) is a rare syndrome characterized bymemory impairment, symptoms of hypothalamic dysfunction, and seizures. It commonly precedes the diagnosis of cancer. Small-cell lung cancer is the neoplasm that is most frequently reported as the etiology underlying PLE. Case Report This report describes a male patient who presented with neurologic symptomsconsistent with anterograde amnesia, apathy, and disorientation. MRI revealed diffuse hyperintensities located predominantly in the medial bitemporal lobes, basal ganglia, frontal lobes, andleptomeninges on fluid attenuated inversion recovery images, suggesting PLE. Study of the primary tumor revealed squamous cell carcinoma of the lung. The patient was treated with neoadjuvant chemotherapy followed by surgery and adjuvant chemoradiotherapy, which resulted in hisneurologic symptoms gradually improving. Conclusions PLE might be a rare debut of squamous cell carcinoma of the lung. Treatment ofthe primary tumor may improve the neurologic symptoms.

Effects of Functional Oils on Coccidiosis and Apparent Metabolizable Energy in Broiler Chickens
Murakami, A.E.,Eyng, C.,Torrent, J. Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.7
The objective of the present study was to investigate the effects of a mixture of functional oils (Essential, Oligo Basics Agroind. Ltda) on performance response of chickens challenged with coccidiosis and the determination of apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), the coefficients of protein and ether extract digestibility and intestinal morphology of broilers fed with diets containing Essential. In Exp. 1, a completely randomized design (CRD) was used, with one control diet without Essential inclusion with coccidiosis (Eimeria acervulina, Eimeria maxima, and Eimeria tenella) challenged birds and two different inclusion rates of Essential (1.5 kg/ton and 2 kg/ton) with coccidiosis-challenged and non-challenged birds for each inclusion rate, using 10 replicates and 50 birds per experimental unit. After 7 d of coccidiosis challenge, the livability was approximately 10% lower (p<0.05) for the control group. Intestinal lesion scores were lower (p<0.05) in the anterior intestine and the cecum for the chickens supplemented. Feed efficiency and growth rate were improved in birds supplemented with Essential (p<0.05) before the coccidiosis challenge and during the first 7 d post infection. In Exp. 2, a CRD was used, with one control diet without Essential inclusion and one diet with inclusion of Essential (1.5 kg/ton), using nine replications and 33 chicks per pen. The diets with Essential yielded approximately 4% higher AME (p = 0.003) and $AME_n$ (p = 0.001). Essential supplementation increased villus height in the jejunum on d 14 (p<0.05). Villus height:crypt depth ratio for the supplemented birds was larger (p<0.05) in the jejunum on d 7, larger (p<0.05) in the jejunum and ileum on d 14. In conclusion, these functional oils improved the energy utilization and the livability and decreased lesions caused by coccidiosis in supplemented birds.

Leonardi, Francesca,Zhang, Qiaoming,Kim, Yun-Hi,Mas-Torrent, Marta Elsevier 2019 Materials science in semiconductor processing Vol.93 No.-
<P><B>Abstract</B></P> <P>Organic semiconductor (OSC):polymer blends are recently increasing their popularity due to the impressive performances they offer once employed as active layer in organic field-effect transistors (OFETs). Here a novel blend formulation composed by the donor-acceptor random copolymer PDPP-TT(1)-SVS(9) and polystyrene has been processed by a solution shearing technique and employed as active material in a thin film transistor. The molecular weight of the polymer binder has revealed to be fundamental for controlling the vertical phase separation and, in turn, for determining the morphological properties of the upper surface which is critical in terms of device stability. The bi-component active layer has been tested as OFET and by using a top gate as electrolyte-gated field-effect transistor (EGOFET). Our strategy based on an OSC:polymer blend processed through a solution shearing technique has demonstrated to be efficient for improving the final device performance in ambient conditions.</P>

Molybdenum release from high burnup spent nuclear fuel at alkaline and hyperalkaline pH
García-Gómez Sonia,Giménez Javier,Casas Ignasi,Llorca Jordi,De Pablo Joan,Martínez-Torrents Albert,Clarens Frederic,Kokinda Jakub,Iglesias Luis,Serrano-Purroy Daniel 한국원자력학회 2024 Nuclear Engineering and Technology Vol.56 No.1
This work presents experimental data and modelling of the release of Mo from high-burnup spent nuclear fuel (63 MWd/kgU) at two different pH values, 8.4 and 13.2 in air. The release of Mo from SF to the solution is around two orders of magnitude higher at pH = 13.2 than at pH = 8.4. The high Mo release at high pH would indicate that Mo would not be congruently released with uranium and would have an important contribution to the Instant Release Fraction, with a value of 5.3%. Parallel experiments with pure non irradiated Mo(s) and XPS determinations indicated that the faster dissolution at pH = 13.2 could be the consequence of the higher releases from metallic Mo in the fuel through a surface complexation mechanism promoted by the OH and the oxidation of the metal to Mo(VI) via the formation of intermediate Mo(IV) and Mo(V) species.

PRIMARY BLACK HOLE SPIN IN OJ 287 AS DETERMINED BY THE GENERAL RELATIVITY CENTENARY FLARE
Valtonen, M. J.,Zola, S.,Ciprini, S.,Gopakumar, A.,Matsumoto, K.,Sadakane, K.,Kidger, M.,Gazeas, K.,Nilsson, K.,Berdyugin, A.,Piirola, V.,Jermak, H.,Baliyan, K. S.,Alicavus, F.,Boyd, D.,Torrent, M. Ca American Astronomical Society 2016 ASTROPHYSICAL JOURNAL LETTERS - Vol.819 No.2
<P>OJ 287 is a quasi-periodic quasar with roughly 12 year optical cycles. It displays prominent outbursts that are predictable in a binary black hole model. The model predicted a major optical outburst in 2015 December. We found that the outburst did occur within the expected time range, peaking on 2015 December 5 at magnitude 12.9 in the optical R-band. Based on Swift/XRT satellite measurements and optical polarization data, we find that it included a major thermal component. Its timing provides an accurate estimate for the spin of the primary black hole, chi = 0.313 +/- 0.01. The present outburst also confirms the established general relativistic properties of the system such as the loss of orbital energy to gravitational radiation at the 2% accuracy level, and it opens up the possibility of testing the black hole no-hair theorem with 10% accuracy during the present decade.</P>
