Autism and Intellectual Disability Associated with Mitochondrial Disease and Hyperlactacidemia
2015
Autism spectrum disorder (ASD) with intellectual disability (ID) is a life-long debilitating condition, which is characterized by cognitive function impairment and other neurological signs. Children with ASD-ID typically attain motor skills with a significant delay. A sub-group of ASD-IDs has been linked to hyperlactacidemia and alterations in mitochondrial respiratory chain activity. The objective of this report is to describe the clinical features of patients with these comorbidities in order to shed light on difficult diagnostic and therapeutic approaches in such patients. We reported the different clinical features of children with ID associated with hyperlactacidemia and deficiencies i…
Inhibition of mechanical activity by neurotensin in rat proximal colon: involvement of nitric oxide.
1997
The aim of the present study was to define the nature of inhibitory action of neurotensin in rat proximal colon. Mechanical activity was detected as changes of intraluminal pressure. Neurotensin (10(-10) to 10(-7) M), in the presence of atropine (10(-6) M), guanethidine (10(-6) M), and nifedipine (10(-8) M), induced a tetrodotoxin-insensitive inhibitory effect characterized by the complete disappearance of the spontaneous phasic contractions. The inhibitory effect of neurotensin (10(-7) M) was abolished by scorpion venom (Leiurus quinquestriatus hebraeus) (10(-6) g/ml) or high K+ (40 mM KCl), whereas it persisted in the presence of omega-conotoxin GVIA, (10(-7) M). N omega-nitro-L-arginine…
Early switch to oral anticoagulation in patients with acute intermediate-risk pulmonary embolism (PEITHO-2) : a multinational, multicentre, single-ar…
2021
BACKGROUND: Current guidelines recommend a risk-adjusted treatment strategy for the management of acute pulmonary embolism. This is a particular patient category for whom optimal treatment (anticoagulant treatment, reperfusion strategies, and duration of hospitalisation) is currently unknown. We investigated whether treatment of acute intermediate-risk pulmonary embolism with parenteral anticoagulation for a short period of 72 h, followed by a switch to a direct oral anticoagulant (dabigatran), is effective and safe. METHODS: We did a multinational, multicentre, single-arm, phase 4 trial at 42 hospitals in Austria, Belgium, France, Germany, Italy, Netherlands, Romania, Slovenia, and Spain. …
4-Aminopyridine and barium chloride attenuate the anti-epileptic effect of carbamazepine in hippocampal slices
1991
The exact mode of action of the anti-epileptic agent carbamazepine is unknown. In hippocampal slices in which epileptiform discharges were induced by addition of penicillin to the perfusion medium, the depressant effect of carbamazepine was attenuated by the potassium-channel blockers barium chloride (0.1 mM) and 4-aminopyridine (200 microM), which suggested that potassium fluxes might be involved in the mechanism of action of carbamazepine.
Detection of flap venous and arterial occlusion using interstitial glucose monitoring in a rodent model.
2010
Background: Free tissue transfer necessitates vigilant postoperative monitoring for vessel occlusion. Unfortunately, most monitoring methods require experienced personnel and are expensive to use. Furthermore, many tests have low sensitivity, low specificity, or significant delay between vessel occlusion and detection. The authors report on a novel method of tissue monitoring that avoids these limitations by tracking interstitial glucose concentration. Methods: Vertical rectus abdominis myocutaneous flaps were elevated in adult rats based on the superior epigastric vessels. Interstitial glucose within the flaps was monitored using a transcutaneous sensor. Interstitial glucose was recorded f…
Association between breastfeeding duration and cognitive development, autistic traits and ADHD symptoms: a multicenter study in Spain
2017
BACKGROUND: Several studies have related longer breastfeeding duration to better intellectual performance in children. By contrast, few studies have investigated the potential protective effects of breastfeeding against behavioral problems such as attention deficit hyperactivity disorder (ADHD) symptoms, and even fewer on autism spectrum disorders (ASD) traits. METHODS: We examined the association between breastfeeding duration and cognitive development, attention, ADHD symptoms, and autistic traits using data from the INMA Project, a Spanish multicenter birth-cohort study, and taking into account the intensity of breastfeeding. Duration of any, predominant, and exclusive breastfeeding was …
Mechanism of the cardiovascular activity of laudanosine: comparison with papaverine and other benzylisoquinolines.
1994
1. The activity of (+/-)-laudanosine, a benzyltetrahydroisoquinoline alkaloid, was investigated in pithed rats and rat isolated aorta. Its effects on [3H]-(+)-cis-diltiazem and [3H]-nitrendipine binding to rat cerebral cortical membranes, and on the different molecular forms of cyclic nucleotide phosphodiesterases (PDE) isolated from bovine aorta were investigated. 2. The dose-response curve to methoxamine (3-300 micrograms kg-1, i.v.) in normotensive pithed rats was shifted to the right by (+/-)-laudanosine, 3 and 6 mg kg-1. 3. (+/-)-Laudanosine inhibited in a concentration-dependent manner the contractile responses evoked by noradrenaline (NA 1 microM), depolarizing solution (KCl 80 mM) o…
Langerin+ DCs regulate innate IL-17 production in the oral mucosa during Candida albicans-mediated infection
2018
The opportunistic fungal pathogen Candida albicans frequently causes diseases such as oropharyngeal candidiasis (OPC) in immunocompromised individuals. Although it is well appreciated that the cytokine IL-17 is crucial for protective immunity against OPC, the cellular source and the regulation of this cytokine during infection are still a matter of debate. Here, we directly visualized IL-17 production in the tongue of experimentally infected mice, thereby demonstrating that this key cytokine is expressed by three complementary subsets of CD90+ leukocytes: RAG-dependent αβ and γδ T cells, as well as RAG-independent ILCs. To determine the regulation of IL-17 production at the onset of OPC, we…
Application of geomarketing to coastal tourism areas
2019
Geomarketing allows geographic units to be defined with a certain degree of homogeneity in terms of tourist preferences, behaviours, needs, expectations, buying and consumption patterns, and analogous attitudes. The result is a “territorial segmentation” of the demand in accordance with the geographic characteristics of tourism areas. The objective of this work is to analyse the strengths and weaknesses of applying geomarketing to the territorial segmentation of demand in coastal tourism areas. An empirical analysis of hotels specialising in family tourism in tourist accommodation establishments in Costa Adeje (Spain) is presented. The main conclusion is that the tourist accommodation varia…
Transition towards a tourist innovation model: The smart tourism destination
2020
Implantation of the smart city model in intermediate tourist towns on their transition to becoming smart destinations involves an inescapable commitment to their habitat and improving the quality of civic life and the economy of cities through more sustainable and technologically advanced elements. Based on this work, the aim is to achieve an overview of the current smart cities paradigm from the standpoint of territorial interest groups, by analysing a tourist town on the Mediterranean coast (Gandia, Valencia) to diagnose its current status. The ultimate aim is to answer the question of whether these intermediate tourist cities are in a position to align themselves with the necessary requi…
