Abstract:
Using a telemetry system with implantable transmitters, we recorded heart rate, electrocardiogram (ECG), body temperature, and locomotor activity continuously in awake, freely moving mice deficient in the thyroid hormone receptor-α1 (TRα1). We have previously reported that the TRα1-deficient mice have a 20% lower mean heart rate and a 0.5°C lower body temperature compared with wild-type control animals. In this study we found that when 3,5,3′-triiodothyronine (T3) was given once a day, there was a parallel increase in heart rate (occurring 1 day later in the TRα1-deficient mice than in control

Abstract:
Background Nerve stimulation with a low-intensity electrical current has become a vital part of the performance of peripheral nerve blockade. The purpose of this study was to compare the accuracy and characteristics of peripheral nerve stimulators used in clinical practice in the United States. Methods Fifteen peripheral nerve stimulators were fitted with fresh batteries and set to deliver currents ranging from 0.1 to 4.0 mA into a series of high-tolerance resistance loads ranging from 1 to 100 komega. The current output, stimulus duration, morphology, frequency, and maximum voltage output wer

Abstract Aims :We report about a 35 year old male patient with severe and frequent epistaxis and hematoma since infancy. He presented with mild thrombocytopenia and increased mean platelet volume. Von Willebrand's disease and subhemophilia had been excluded. Previously, he was diagnosed with immune thrombocytopenic purpura. He never underwent elective surgery. His parents were asymptomatic. However, his young daughter also suffers from severe bleeding symptoms and was referred to our coagulation outpatient clinic to investigate the bleeding disorder.

Abstract:
In cartilage tissue engineering, biphasic scaffolds (BSs) have been designed not only to influence the recapitulation of the osteochondral architecture but also to take advantage of the healing ability of bone, promoting the implant’s integration with the surrounding tissue and then bone restoration and cartilage regeneration. This study reports the development and characterization of a BS based on the assembly of a cartilage phase constituted by fibroin biofunctionalyzed with a bovine cartilage matrix, cellularized with differentiated autologous pre-chondrocytes and well attached to a bone ph

Purpose Advances in the design and manufacturing of novel synthetic bioactive scaffolds as bone substitute in bone reconstruction are at the forefront of orthopedic study due to their excellent biological performances. However, fabricating bioactive scaffolds with similar osteogenic and mechanical properties of a natural bone still remains a challenge. Our aim was to produce functional bioactive scaffolds with biologically interactive ions, microstructure for cell proliferation and a suitable biodegradation rate in critical-size bone defect.

Abstract:
La proportion de cables moyenne tension se developpe. Edf envisage de generaliser l'emploi de bobine de compensation dans les reseaux moyenne tension mixte. Ainsi la plupart des defauts monophases sont autoextincteurs et la plupart des defauts permanents sont des defauts a arc intermittent. Il est donc necessaire que les protections employees pour selectionner le depart en defaut exploitent le regime transitoire qui se produit a l'apparition du defaut. Pour etudier ces regimes transitoires, un circuit electrique equivalent simple, utilisant les composantes naturelles du reseau est realise. Sa

Abstract:
La mise à la terre du point neutre des réseaux de distribution par une bobine de compensation réduit le courant de défaut lors d'un défaut monophasé, ce qui est le type de défaut le plus souvent rencontré dans l'exploitation. Cette mesure améliore la qualité de service, mats rend la détection et la localisation de défauts plus difficiles. Cette thèse traite de la localisation de défauts à faible résistance, auto-extincteurs ou permanents dans les réseaux compensés arborescents. Les phénomènes transitoires lors d'un défaut sont étudiés et une nouvelle approche pour la localisation est développé

Abstract:
Dans un réseau d'énergie électrique, les génératrices synchrones sont soumises à des régimes transitoires qui conditionnent leur stabilité et leur tenue mécanique. Nous considérons le cas d'une centrale hydroélectrique, équipée de machines synchrones à pôles saillants pouvant fonctionner en générateur (turbine) et en moteur (pompe). Une telle centrale est généralement reliée au réseau général par une ligne à haute tension qui peut être affectée par des défauts fugitifs. Nous étudions le comportement d'une machine synchrone, lorsque la liaison, affectée d'un court-circuit monophasé, est tempora

Bien identifier les defauts, pour mieux alimenter les clients, devrait permettre, a terme, d'optimiser la maintenance des reseaux et d'augmenter la duree de vie des ouvrages. Actuellement, dans les postes htb/hta qui sont instrumentes, l'acquisition des signaux se fait au mieux avec une frequence d'echantillonnage de 10 khz. Elle est plus couramment egale a 3 khz, ce qui semble insuffisant pour la reconnaissance des defauts. De plus, pour la plupart des signaux qui sont disponibles,
