Abstract
This paper details the design and implementation of a photovoltaic current - voltage (I-V) tracer. The I-V tracer employs a capacitive load controlled by a raspberry pi model 4B. The complete measurement system includes protections, capacitor charging/discharging power electronics and current, voltage, irradiance and temperature sensors. Results, which include maximum power point, open circuit voltage, short circuit current and module efficiency, are displayed on an LCD touch display. Detailed description of the required software and the graphical user interface is also presented. This measurement system is very useful for testing photovoltaic installations, allowing an immediate verification whether the panels fulfill with the specifications and detection of possible failures.

Abstract
OBJECTIVE Immune-mediated inflammatory diseases (IMID) are chronic and highly disabling diseases that share inflammatory sequences and immunological dysregulations. Considered as a disease in itself, the prevalence of IMID is virtually unknown. The aim of this study was to assess the prevalence of 10 selected UDI, including rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis, ulcerative colitis, Crohn's disease, systemic lupus erythematosus, hidradenitis suppurativa, sarcoidosis and uveitis in Spain. METHODS cross-sectional epidemiological study of point prevalence was made. This study was carried out through a series of computerized interviews in households chosen at random in 17 autonomous communities in Spain. A structured questionnaire was used to determine the frequency of diagnosis and the concurrence of 10 IMID in the respondents and other individuals belonging to the same family nucleus. The point prevalence estimates were used and compared with the objective of determining the frequency of IMID by age, sex and communities. The data were processed using Excel 2016 (Microsoft, Redmond, WA, USA) and the SPSS V.019 system (IBM Corp. Armonk, NY, USA) for statistical analysis using the usual statistical tests in this type of studies. RESULTS Of the 7,980 respondents, 510 were diagnosed with an IMID, representing a cross-sectional study of 6.39% (95% CI: 6.02-6.76). One, two, three or more members of the family were affected in 87.2%, 7.8% and 5% of positive relatives in IMID, respectively. The most recurrent diseases were psoriasis (2.69% [95% CI: 2.32-3.06]) and rheumatic arthritis (1.07% [95% CI: 0.70-1.44]). There were differences in prevalence due to sex (p = 0.004) and age (p = 0.000). No significant differences were identified related to geographic location (p = 0.819). Attendance of at least 2 IMID was reported in 8.9% of respondents. CONCLUSIONS The overall prevalence was of the IMID studied was 6.39%, psoriasis being the most frequent with 2.69%. This study constitutes an initial step to consider IMID as an independent disease within the health system..

Abstract
Compounds targeting phosphatidylinositol-3-kinase/mammalian target of rapamycin (PI3K/mTOR) signaling are being investigated in multiple clinical settings, but drug resistance may reduce their benefit. Compound rechallenge after drug holidays can overcome such resistance, yet little is known about the impact of drug holidays on cell biochemistry. We found that PI3K inhibitor (PI3Ki)-resistant cells cultured in the absence of PI3Ki developed a proliferative defect, increased oxygen consumption and accumulated reactive oxygen species (ROS), leading to lactate production through hypoxia-inducible factor-1α. This metabolic imbalance was reversed by mammalian target of rapamycin complex 1 (mTORC1) inhibitors. Interestingly, neither AKT nor c-MYC was involved in mediating the metabolic phenotype, despite the latter contributing to resistant cells' proliferation. These data suggest that an AKT-independent PI3K/mTORC1 axis operates in these cells. The excessive ROS hampered cell division, and the metabolic phenotype made resistant cells more sensitive to hydrogen peroxide and nutrient starvation. Thus, the proliferative defect of PI3Ki-resistant cells during drug holidays is caused by defective metabolic adaptation to chronic PI3K/mTOR pathway inhibition. This metabolic imbalance may open the therapeutic window for challenge with metabolic drugs during drug holidays.

Abstract
BACKGROUND Brain activity is less organized in patients with schizophrenia than in healthy controls (HC). Noise power (scalp-recorded electroencephalographic activity unlocked to stimuli) may be of use for studying this disorganization. Method Fifty-four patients with schizophrenia (29 minimally treated and 25 stable treated), 23 first-degree relatives and 27 HC underwent clinical and cognitive assessments and an electroencephalographic recording during an oddball P300 paradigm to calculate noise power magnitude in the gamma band. We used a principal component analysis (PCA) to determine the factor structure of gamma noise power values across electrodes and the clinical and cognitive correlates of the resulting factors. RESULTS The PCA revealed three noise power factors, roughly corresponding to the default mode network (DMN), frontal and occipital regions respectively. Patients showed higher gamma noise power loadings in the first factor when compared to HC and first-degree relatives. In the patients, frontal gamma noise factor scores related significantly and inversely to working memory and problem-solving performance. There were no associations with symptoms. CONCLUSIONS There is an elevated gamma activity unrelated to task processing over regions coherent with the DMN topography in patients with schizophrenia. The same type of gamma activity over frontal regions is inversely related to performance in tasks with high involvement in these frontal areas. The idea of gamma noise as a possible biological marker for schizophrenia seems promising. Gamma noise might be of use in the study of underlying neurophysiological mechanisms involved in this disease.

Abstract
INTRODUCTION For the most part, what makes us different from other animal species is comprised within our brain. However, there is no single factor, no singular reason accounting for the difference between our brain and others; rather, differences appear multiple. DEVELOPMENT AND CONCLUSIONS Here we perform an up-to-date review of the main divergences between ours and other species' brains, which might be explaining the singularities of our behavior. When brain volume is on focus, it can be appreciated that our brain is certainly large both in relative and absolute terms, being also the case that some subdivisions of the prefrontal regions, as much as the parietal or temporal lobes appear notably increased in size relative to other brain areas. Also at variance with other species, our brain is consistently more asymmetric. But differences also involve the cellular level. In this regard, they have been reported different and peculiar proportions of neurons both within and between cortical columns, as much as certain types of neurons (like fusiform and mirror neurons) that, even if they are not exclusively human, they display in our species peculiar quantitative and functional features. Finally, neuronal receptor systems seem to exhibit exclusively human traits that might be crucial to understanding some of the singularities of the evolution of our brain.

Abstract
Event-related potentials (ERPs) provide information about the temporal course of cognitive processes in the brain. They have proved to be a valuable tool in order to explore semantic aspects of word processing. However, to date, research in this field has been mostly concerned with the study of post-lexical features by means of the N400-paradigm. We introduce here the rapid stream stimulation paradigm, in which stimuli reflecting different levels of linguistic information are presented to subjects at a high rate of stimulation. The present protocol shows in detail how this paradigm can be applied. The application of the rapid stream stimulation paradigm evokes the recognition potential (RP), an ERP component that peaks at around 260 ms after stimuli onset and seems to be reflecting lexical selection processes. Results of studies that revealed the sensibility of the RP to visual-semantic aspects and the location of its neural generators within basal extrastriate areas are reported. Although some research has been conducted with the rapid stream stimulation paradigm much remains still to be done. Some of the possibilities that this paradigm offers are further discussed.

Abstract
Some theoretical perspectives propose a semantic system in which categories are represented in different brain regions. Others assume that distinctions are based rather on differences in the demands placed by different categories on shared processing systems. In this study semantic categorization processes were investigated using the recognition potential (RP), an event-related brain response that reflects semantic processing, peaks at around 250 ms after stimulus onset and originates in areas subserving perceptual-semantic analyses. Results indicate that the RP shows some degree of sensitivity to categorization processes, but that categories assumed to differ markedly in their processing demands share, to a large extent, a common neural generator. This provides support for the non-categorical view on the organization of the semantic system, though introducing subtle variations, and suggesting the existence of a semantic subsystem specializing in the processing of perceptual-semantic features regardless of the semantic category involved.

Abstract
Previous research on open- and closed-class words has revealed the existence of several differences in the processing of these types of vocabulary. In this paper the processing of open- and closed-class words was compared by means of an early electrical brain response, recognition potential (RP), which indexes semantic processing and originates from basal extrastriate areas. The effects of word frequency on closed-class words were also investigated. For these purposes, open- and closed-class words, among other stimuli, were presented by means of the rapid stream stimulation procedure. Results showed that there were no significant differences when comparing the RP evoked by open- and closed-class words in the left hemisphere. However, in the right hemisphere this situation changed: the RP evoked by open- and closed-class words did differ. Moreover, there were no differences between the RP evoked by closed-class words and pseudowords. These patterns of results suggest that the semantic processing of closed-class words shares some aspects with the processing of open-class words, despite the existence of some differences. Thus, whereas the semantic processing of open-class words recruits brain areas of both hemispheres, the semantic processing of closed-class words is left-lateralized. A second purpose of this work is to study word-frequency effects on closed-class words. Our results show the insensitivity of closed-class words to word-frequency effects.

Abstract
An 18-year-old woman in her first pregnancy with hyperemesis gravidarum, presented dehydration, without hyponatremia. She was confused with profound disorientation, apathy, and drowsiness. She presented upbeating nistagmus on upward gaze and gate ataxia recognised as Wernicke's encephalopathy. Laboratory tests demonstrated hypokalemia, hypernatremia and aminotransferase elevation. The serum osmolality was 319 mOsm/kg and the water deficiency 2.73 l. The patient developed weakness in the four limbs, with hypotonicity, absence of tendon reflexes and showed bilateral Babinski signs. A T2 weighted sagittal cranial-magnetic resonance imaging revealed a high signal within mid-pons suggesting central pontine myelinolysis. In this case we highlight the absence of hyponatremia. Furthermore, the central pontine myelinolysis was probably secondary to hypokalemia, hypernatremia and hyperosmolality.

Abstract
The results from a cohort of frequent consulters with chronic diseases that were followed up for 20 years were evaluated according to morbidity and use of health services; these indicators were compared in two subgroups, not randomly selected, defined on whether any type of health intervention was carried out or not. Although the intervention group consulted more times, this difference disappeared when the comparison was stratified for the number of chronic diseases; in addition, there were no differences in the mean number of prescriptions between both groups. It is concluded that the effects of social factors should receive a greater attention; effort should be focused in approaches not exclusively based on health care, as these only partially explain the morbidity and use of health services by frequent consulters.
