GABAergic basal forebrain afferents innervate selectively GABAergic targets in the main olfactory bulb
2010
In this work we have analyzed the targets of the GABAergic afferents to the main olfactory bulb originating in the basal forebrain of the rat. We combined anterograde tracing of 10 kD biotinylated dextran amine (BDA) injected in the region of the horizontal limb of the diagonal band of Broca that projects to the main olfactory bulb, with immunocytochemical detection of GABA under electron microscopy or vesicular GABA transporter (vGABAt) under confocal fluorescent microscopy. GABAergic afferents were identified as double labeled BDA-GABA boutons. Their targets were identified by their ultrastructure and GABA content. We found that GABAergic afferents from the basal forebrain were distribute…
Ascending projections from the optic tectum in the lizard Podarcis hispanica.
1998
The ascending projections of the optic tectum, including their cells of origin, have been studied in the lizard Podarcis hispanica by means of a two-step experimental procedure. First, tracers were injected in the tectum to study the anterograde labeling in the forebrain. Second, the cells of origin of these projections have been identified by analyzing the retrograde labeling after tracer injections in the thalamus, hypothalamus, and pretectum. Three main tectal ascending pathways have been described: the dorsal tecto-thalamic tract (dtt), the medial tecto-thalamic tract (mtt), and the ventral tecto-thalamic tract (vtt). The dtt originates in radial cells of layers 5 and 7 and bipolar cell…
Reproducibility of pulse wave velocity and augmentation index derived from non-invasive occlusive oscillometric tonometry analysis in adolescents
2018
The aim of this study was to investigate the short-term reproducibility of aortic pulse wave velocity (PWVao) and augmentation index (AIx%) assessed by the non-invasive oscillometric device. Altogether of 55 (19 boys, 36 girls) adolescents 16-19-years-of-age participated in the study. PWVao and AIx% were measured during the same laboratory visit at 2 min intervals using the Arteriograph™ device. Peak oxygen uptake (VO2peak ) was assessed by the maximal exercise test on a cycle ergometer and body fat percentage by bioelectrical impedance analysis. We studied reproducibility using intraclass correlation coefficients (ICC), coefficient variation with the root-means-square method expressed as p…
Prediction of leukocyte counts during paediatric acute lymphoblastic leukaemia maintenance therapy
2019
Maintenance chemotherapy with oral 6-mercaptopurine and methotrexate remains a cornerstone of modern therapy for acute lymphoblastic leukaemia. The dosage and intensity of therapy are based on surrogate markers such as peripheral blood leukocyte and neutrophil counts. Dosage based leukocyte count predictions could provide support for dosage decisions clinicians face trying to find and maintain an appropriate dosage for the individual patient. We present two Bayesian nonlinear state space models for predicting patient leukocyte counts during the maintenance therapy. The models simplify some aspects of previously proposed models but allow for some extra flexibility. Our second model is an ext…
Early-onset tolerance in rat global cerebral ischemia induced by a mitochondrial inhibitor
2000
It was studied whether a subtoxic dose of the mitochondrial neurotoxin, 3-nitropropionic acid (3-NPA), can initiate early-onset tolerance induction for subsequent ischemic injury. Wistar rats were pretreated for 3 h by intraperitoneal 3-NPA (20 mg/kg body weight; n=13) or solvent (n=12). Fifteen minutes global cerebral ischemia was induced by bilateral carotid artery occlusion and hypobaric hypotension. rCBF and tissue hemoglobin oxygen saturation were measured by laser Doppler scanning and a microspectrophotometric method. Ischemic insult and brain temperature were identical in both groups. Body weight and neurological scores recovered in the pretreated group but further deteriorated in th…
Allometrically scaled explosive strength, but not static strength or maximal oxygen uptake is associated with better central processing time in young…
2020
BACKGROUND: We aimed to examine the associations of cardiorespiratory fitness (CRF), static strength and explosive strength with cognitive functions in young males. METHODS: Eighty-six young males (age 16-24 years) participated in the study and took part in a number of tests including: static strength (grip strength test), explosive strength (Sargent jump test), and CRF (via direct measure of maximal oxygen uptake (VO2max)). Static strength and explosive strength were scaled by allometrically modeled skeletal muscle mass (SMM) and height while VO2max was scaled by SMM and body mass (BM). Cognition was assessed by inhibitory control, simple and choice reaction time tasks using computerized C…
14q13.1-21.1 deletion encompassing the HPE8 locus in an adolescent with intellectual disability and bilateral microphthalmia, but without holoprosenc…
2011
Interstitial deletions involving 14q13.1q21.1 are rare. In the literature at least 10 cases involving this region have been described and all patients showed a phenotype within the holoprosencephaly (HPE) spectrum. Previous studies suggested the HPE8 region as a candidate locus for HPE at 14q13. We report an adolescent with a 14q13.1q21.1 deletion encompassing the HPE8 region associated with intellectual disability (ID), bilateral microphthalmia, and coloboma, without cerebral anomalies typical of HPE. Except for ocular defects (i.e., microphthalmia, coloboma) consistent with HPE-type anomalies, the minor facial dysmorphia was not suggestive for HPE and the absence of cerebral anomalies sho…
Réécriture et reformulation des topiques descriptifs du ġazal homoérotique dans le Nasīm al-ṣabā (La brise du vent d’est) d’Ibn Ḥabīb al-Ḥalabī (m. 1…
2023
In his work entitled Nasīm al-ṣabā (The Breeze of the East Wind), Ibn Ḥabīb al-Ḥalabī (d. 1377) dedicates a chapter to the description of a young man (ġulām). This chapter is characterized by the presence of two parts which differ from a stylistic point of view. This paper deals with the central part of the chapter, which is entirely descriptive. The description of the ephebe in this central part shows great detail both descriptively (regarding the physical features of the ephebe) and thematically (regarding the topics used). In this part, the descriptive topics of the ephebe present in the classical homoerotic ġazal are transposed and reformulated in saǧ‘ (rhymed prose). A salient feature …
¿Por qué la literatura?
2021
In poetry, as well as in a good part of prose works, the rhythm of words is the music that governs reason and emotion. Literature occupies an important place in my creation. In this article I describe the different procedures in which I configure its presence in my music and the main themes in four of my works: Envoi, Como el viento, Maya and Transmutación.
OnMLM: An Online Formulation for the Minimal Learning Machine
2019
Minimal Learning Machine (MLM) is a nonlinear learning algorithm designed to work on both classification and regression tasks. In its original formulation, MLM builds a linear mapping between distance matrices in the input and output spaces using the Ordinary Least Squares (OLS) algorithm. Although the OLS algorithm is a very efficient choice, when it comes to applications in big data and streams of data, online learning is more scalable and thus applicable. In that regard, our objective of this work is to propose an online version of the MLM. The Online Minimal Learning Machine (OnMLM), a new MLM-based formulation capable of online and incremental learning. The achievements of OnMLM in our…
