MOLECULAR SIGNALLING RESPONSE TO SHORT DURATION HIGH INTENSITY/LOW VOLUME RESISTANCE TRAINING IN HUMAN SKELETAL MUSCLE.

2014

Introduction Resistance training (RT) is one of the most important stimuli for muscle hypertrophy, but it may play also an important role on weight loss and fat acid (FA) oxidation increase. It has been largely demonstrated that RT affects anabolic signalling molecule phosphorylation but, considering the numerous variables of RT, the differences between training modalities has been till now poorly investigated. The aim of this study was to assess Akt, 4EBP1, S6 and AMPK, ACC signalling after a single bout of high-intensity resistance training (HIRT) and of traditional resistance training (TRT). Methods 12 healthy subjects performed in two different moments and with different legs HIRT and T…

Solvent impact on the planarity and aromaticity of free and monohydrated zinc phthalocyanine: a theoretical study

2017

A theoretical investigation on the planarity of molecular structure of zinc phthalocyanine (ZnPc) and its aromaticity has been performed using B3LYP and M06-2X density functionals combined with selected Pople-type basis sets. The effect of the applied calculation method on the optimized structure of ZnPc and ZnPc∙∙∙H2O, both in the gas phase and in the polar solvent, was analyzed. To quantify the aromaticity of the ZnPc and ZnPc∙∙∙H2O complexes, both the geometric and magnetic criteria, i.e., Harmonic Oscillator Model of Aromaticity (HOMA) index and the nucleus-independent chemical shift (NICS) values at the centers or 1 A above the centers of structural subunits, were calculated. The energ…

Toward Mechanistic Design of Surrogate Buffers for Dissolution Testing of pH-Dependent Drug Delivery Systems

2020

The in vivo dissolution of enteric-coated (EC) products is often overestimated by compendial in vitro dissolution experiments. It is of great interest to mimic the in vivo conditions as closely as possible in vitro in order to predict the in vivo behavior of EC dosage forms. The reason behind this is the overly high buffering capacity of the common compendial buffers compared to the intestinal bicarbonate buffer. However, a bicarbonate-based buffer is technically difficult to handle due to the need for continuous sparging of the media with CO2 to maintain the desired buffer pH. Therefore, bicarbonate buffers are not commonly used in routine practice and a non-volatile alternative is of inte…

Contact Sensitizers Specifically Increase MHC Class II Expression on Murine Immature Dendritic Cells

2000

Contact sensitivity is a T-cell-mediated immune disease that can occur when low-molecular-weight chemicals penetrate the skin. In vivo topical application of chemical sensitizers results in morphological modification of Langerhans cells (LC). Moreover, within 18 h, LC increase their major histocompatibility complex (MHC) class II antigens expression and migrate to lymph nodes where they present the sensitizer to T lymphocytes. We wanted to determine if such an effect could also be observed in vitro. However, because of the high genetic diversity encountered in humans, assays were performed with dendritic cells (DC) obtained from a Balb/c mouse strain. The capacity of a strong sensitizer, DN…

Screening of the USH1G gene among Spanish patients with Usher syndrome. Lack of mutations and evidence of a minor role in the pathogenesis of the syn…

2007

The Usher syndrome (USH) is an autosomal recessive hereditary disorder characterized by the association of sensorineural hearing loss, retinitis pigmentosa (RP) and, in some cases, vestibular dysfunction. The USH1G gene, encoding SANS, has been found to cause both Usher syndrome type I and atypical Usher syndrome. 109 Spanish unrelated patients suffering from Usher syndrome type I, type II, type III and unclassified Usher syndrome were screened for mutations in this gene, but only eight different changes without a clear pathogenic effect have been detected. Based on these results as well as previous studies in other populations where mutational analysis of this gene has been carried out, on…

De novo 13q deletions in two patients with mild anorectal malformations as part of VATER/VACTERL and VATER/VACTERL-like association and analysis of E…

2013

Item does not contain fulltext Anorectal malformations (ARMs) comprise a broad spectrum of conditions ranging from mild anal anomalies to complex cloacal malformations. In 40-50% of cases, ARM occurs within the context of defined genetic syndromes or complex multiple congenital anomalies, such as VATER/VACTERL (vertebral defects [V], ARMs [A], cardiac defects [C], tracheoesophageal fistula with or without esophageal atresia [TE], renal malformations [R], and limb defects [L]) association. Here, we report the identification of deletions at chromosome 13q using single nucleotide polymorphism-based array analysis in two patients with mild ARM as part of VATER/VACTERL and VATER/VACTERL-like ass…

Genetic syndrome suspicion: examples of clinical approach in the neonatal unit.

2010

Overgrowth syndromes: the practical clinical approach. Excessive growth can be present in a variety of medical conditions as result of abnormal fetal metabolism (i.e., maternal gestational diabetes) or of an overgrowth syndrome. Within this latter group of diseases, a LGA newborn requires a complex differential diagnosis encompassing several syndromes, such as Beckwith-Wiedemman, Sotos, Weaver, Simpson-Golabi-Behmel, Perlman, and Bannayan-Riley-Ruvalcaba. Partial or global overgrowth, other dysmorphisms, abdominal organs anomalies, as well as benign and malignant tumors are the common issues to examine for the diagnosis and the monitoring of all these disorders. The molecular bases of these…

Fabrication of elastomeric scaffolds with curvilinear fibrous structures for heart valve leaflet engineering

2014

Native semi-lunar heart valves are composed of a dense fibrous network that generally follows a curvilinear path along the width of the leaflet. Recent models of engineered valve leaflets have predicted that such curvilinear fiber orientations would homogenize the strain field and reduce stress concentrations at the commissure. In the present work, a method was developed to reproduce this curvilinear fiber alignment in electrospun scaffolds by varying the geometry of the collecting mandrel. Elastomeric poly(ester urethane)urea was electrospun onto rotating conical mandrels of varying angles to produce fibrous scaffolds where the angle of fiber alignment varied linearly over scaffold length.…
