Carcinoma bronquiolo-alveolar en perro : un caso clínico. Diagnóstico y tratamiento quirúrgico
Se describe un caso clínico de un perro Staffordshire Bull Terrier macho de 2 años de edad que presentaba un historial de insuficiencia respiratoria. Tras la exploración física, se aprecia la existencia de un derrame pleural procediéndo-se a realizar diferentes pruebas diagnósticas para establecer su causa incluyendo la toracocentesis y cultivo bacteriológico, radiología y ecografía torácica. Se describe la vía de abordaje quirúrgico uti- lizada en este caso (esternotomía mediana); así como, la intervención de lobectomía a la que fue sometido el paciente. La pieza de extirpación quirúrgica fue remitida para su análisis histopatolóqico, confirmando el diagnóstico de carcinoma bronquiolo-alveolar primario de pulmón.A clinical case is described of a two year oid male Staffordshire Bull Terrier who was sent with a history of respiratory insufficiency. After a physical examination a pleural effusion was found preceeding various diagnostics such as thoracocentesis, bacteriological culture, thoracic radiographs and an ultrasound were issued to establish the cause. The surgical approach (medium esternotomy) and the lobectomy the patient suffered from are described. The surgical sample was sent to be analised histopatholoqícally, confirming the pulmonary primary bronchiolar-alvcolar carcinoma diagnostic
Enhancing MRI Reconstruction Efficiency Through Multi-GPU Parallelization
Dynamic cardiac MRI (cMRI) is essential for diagnosing
cardiovascular diseases, demanding high resolution and image
quality. However, achieving superior quality increases data
volume and reconstruction time. To tackle this, we propose
a solution using parallel imaging and Compressed Sensing
(CS) with high-capacity computing devices (e.g., GPUs) for
accelerated reconstruction of undersampled data. GPU mem-
ory limitations, especially in 3D cMRI, present challenges.
Our scalable approach splits the reconstruction problem and
employs multiple GPUs (or multiple multi-core CPUs) to per-
form multiple optimizations in parallel using the well-known
NESTA algorithm, while preserving smoothness between ad-
jacent frames in the temporal dimension. Preliminary results
on 5D cMRI reconstruction show that our parallel proposal
achieves equivalent reconstruction quality in less time, en-
abling larger data processing and cost reduction with smaller,
more affordable GPUs, as opposed to a single, highly expensive
GPU. Moreover, the adoption of the OpenCLIPER frame-
work eliminates proprietary GPU technologies. Exploration of
adaptability to other sampling schemes opens new possibilities
in this field.This work is partially supported by MINECO under

The paradoxical relationship between emotion regulation and gambling-related cognitive biases
The funding agency is public and played no role in planning or executing this work, nor interfered with the collection and interpretation of data.Background
Gambling behavior presents substantial individual variability regarding its severity, manifestations,
and psychological correlates. Specifically, differences in emotion regulation, impulsivity,
and cognitive distortions have been identified as crucial to describe individual profiles
with implications for the prevention, prognosis, and treatment of gambling disorder (GD).
Aims and method
The aim of the present study was to investigate the associations of gambling-related cognitions
(measured according to the GRCS model) with impulsivity (UPPS-P model) and emotion
regulation (CERQ model), in a sample of 246 gamblers with different levels of gambling
involvement, using mixed-effects modelling to isolate theoretically relevant associations
while controlling for the potentially confounding effects of sociodemographic and clinical
covariates.
Results
Affective/motivational dimensions of UPPS-P impulsivity positive urgency and sensation
seeking, on the one hand, and CERQ emotion regulation strategies reappraisal, rumination
and blaming others, on the other, independently and significantly predicted distorted gambling-
related cognitions.
Conclusions
These results (a) reinforce the ones of previous studies stressing the relevance of emotional
and motivational processes in the emergence of gambling-related cognitive distortions; and
(b) replicate the seemingly paradoxical finding that gamblers use emotion regulation strategies
customarily considered as adaptive (i.e. reappraisal) to strengthen and justify their
biased beliefs about gambling outcomes and controllability.Supported by a grant from the Spanish Government (Ministerio de Economía y Competitividad, Secretaría de Estado de Investigación, Desarrollo e Innovación; Convocatoria 2017 de Proyectos I+D de Excelencia, Spain; co-funded by the Fondo Europeo de Desarrollo Regional, FEDER, European Union), with reference number PSI2017-85488-
The role of impulsivity in dropout from treatment for cigarette smoking
AbstractImpulsivity is a variable that has been associated with drug use. This study analyzes impulsivity from two different paradigms, one considering it as a trait and the other based on its behavioral correlates, such as disinhibition and impulsive decision-making in the treatment prognosis (maintain abstinence, relapse and dropout) of smokers after outpatient treatment. The participants in the study were 113 smokers who requested treatment for nicotine addiction. They were assigned to three groups according to whether or not they remained abstinent one month after beginning treatment; thus, group 1 was abstinent, group 2 had relapsed, and group 3 had dropped out of treatment. The participants filled out the Semi-structured Interview for Smokers, the Fargerström Test for Nicotine Dependence, the Temperament and Character Inventory-Revised (TCI-R) and the Delay Discounting Task (DDT). The Delay Discounting variable presents lower scores in the dropout group than in the relapse and abstinent groups, with the highest scores in the relapse group. Differences were also found on the Harm Avoidance (HA) variable, with lower scores in the dropout group compared to the relapse group. The importance of these results lies in the consideration of the smoker’s personality profile in order to prevent both dropout and relapse
Dynamics of magnetic assembly of binary colloidal structures

the bottom-up manufacturing of smart materials whose properties can be precisely modulated by
non-contact forces. Here, we study the MF-directed assembly in binary colloids made up of strong
ferromagnetic and diamagnetic microparticles dispersed in ferrofluids. We present observations
of the aggregation of pairs and small groups of particles to build equilibrium assemblies. We
also develop a theoretical model capable of solving the aggregation dynamics and predicting the
particle trajectories, a key factor to understand the physics governing the MF-directed assembly.The project MINECO FIS2013-41821-R (Spain) is acknowledged for financial support
Reconsidering the roots, structure, and implications of gambling motives: An integrative approach
The present study identified Social, Financial, and Fun/thrill-related gambling motives factors,
but also a fourth factor in which some positive and negative reinforcement-based
motives were grouped into a single and broader Affect regulation factor. This Affect regulation
factor shared variance both with BIS and BAS-related measures, and was the only
direct predictor of disordered gambling symptoms. The Fun/thrill factor was directly related
to frequency of participation in high-arousal, skill-based games, and all factors were related
to participation in lower-arousal, chance games (with Social motives negatively predicting
both participation in the latter and total severity). In the SEM model, measures of BIS/BAS
sensitivity were connected to gambling behavior only through gambling motives. Based on
measures of items’ specificity, a shortened Spanish scale (the brief Gambling Motives
Inventory, bGMI) is proposed to assess gambling motives in accordance with the observed
4-factor structure.This work is supported by a grant from

Caffeinated Energy Drinks Boost Physical Performance In Several Sport Modalities: Should They Be Considered By Antidoping Authorities?
Caffeine has been consumed by man for centuries although the
manner of consumption has varied among different geographical
zones, according to the source of caffeine present in natural foods
(e.g., coffee, tea, mate, guaraná, kola, etc.). By the end of XIX century,
John S. Pemberton created the first non-natural caffeinated-beverage
that contained caffeine form the kola nut. The use of this beverage –
universally known as Coca-Cola- increased exponentially worldwide
and favored the apparition of hundreds of commercial caffeinated
drinks with similar characteristics. Although first energy drinks were
marketed in Thailand in the 1970s, these drinks became widely popular
when they were introduced in the European in the 1990s. Despite the
commercial availability of numerous caffeinated beverages and foods,
energy drinks have gained popularity in the last years, likely because
they provide a higher dose of caffeine per serv
HBPEI-grafted carbon nanotubes for the effective retention of Pd2+ and Pt2+ through complexation
Hyperbranched poly(ethyleneimine) (HBPEI) molecules in solution present high capacity to form stable
complexes with transition metal ions due to the large number of amino groups ready to form chelates.
We grafted HBPEI molecules to a multi-walled carbon nanotube (MWCNT) surface through covalent
bonding, preparing solid hybrids which retain the chemical properties of the free poly-alkylamine molecules. In this way, we are able to transfer the complexation capacity of such molecules to a solid material
adequate to act as a high-capacity sorbent for metal transition ions. We tested the HBPEI/MWCNT
hybrids for the retention of Pd2+ and Pt2+ and the retention values obtained are much larger than those
previously reported with fast retention kinetics. The kinetics and the XPS analysis of the metal ion/HBPEI/
MWCNT ensemble indicate that the retention takes place through the formation of chelates with two or
three nitrogen atoms and with Cl− anions as co-ligands. Moreover, the results allow us to tune the metal
loading on the hybrids by controlling the solution conditions. This is important because the XPS valence
band analysis demonstrates that metal complexation directly modifies the electronic behaviour of the
carbon nanotubes, which supports the stable covalent bond between HBPEI molecules and MWCNT and
opens the possibility for tuning the electronic properties of the tubes.The financial support of the MINECO (projects MAT2014-
