Dynamic evolution of mitochondrial genomes in Trebouxiophyceae, including the first completely assembled mtDNA from a lichen-symbiont microalga (Treb…
2019
AbstractTrebouxiophyceae (Chlorophyta) is a species-rich class of green algae with a remarkable morphological and ecological diversity. Currently, there are a few completely sequenced mitochondrial genomes (mtDNA) from diverse Trebouxiophyceae but none from lichen symbionts. Here, we report the mitochondrial genome sequence of Trebouxia sp. TR9 as the first complete mtDNA sequence available for a lichen-symbiont microalga. A comparative study of the mitochondrial genome of Trebouxia sp. TR9 with other chlorophytes showed important organizational changes, even between closely related taxa. The most remarkable change is the enlargement of the genome in certain Trebouxiophyceae, which is princ…
Progressive Characterization of Visual Phenotype in Bardet-Biedl Syndrome Mutant Mice
2019
Purpose Bardet-Biedl syndrome (BBS) is an archetypical ciliopathy caused by defective ciliary trafficking and consequent function. Insights gained from BBS mouse models are applicable to other syndromic and nonsyndromic retinal diseases. This progressive characterization of the visual phenotype in three BBS mouse models sets a baseline for testing therapeutic interventions. Methods Longitudinal acquisition of electroretinograms, optical coherence tomography scans, and visual acuity using the optomotor reflex in Bbs6/Mkks, Bbs8/Ttc8, and Bbs5 knockout mice. Gene and protein expression analysis in vivo and in vitro. Results Complete loss of BBS5, BBS6, or BBS8 leads to different rates of reti…
The Fontan-Operation: From Intra- to Extracardiac Procedure
2003
Purpose For treatment of univentricular heart, the Fontan operation has been established as the definitive palliation. The current controversy is mainly based on the high incidence of arrhythmias after an intra-atrial lateral tunnel Fontan operation. Methods From January 1995 until April 2002. 46 children underwent a Fontan-type operation with or without a small fenestration. In 33 patients (group I) an Intracardiac tunnel and in 13 patients (group II) an extracardiac conduit procedure was performed. Principal findings There was no perioperative mortality. All patients showed postoperative a significant increase of arterial oxygen saturation, from 76 to 86% after surgery with fenestration, …
Evaluation of the plasmatic level of mepivacaine in different anatomical regions
2018
Background To evaluate the serum level of the local anesthetic mepivacaine 3% without vasoconstrictor in patients who underwent procedures performed in the anterior and posterior maxilla, through a method of possible extraction to quantify it in human plasma by high performance liquid chromatography (HPLC). Material and Methods This was a hybrid study consisting of 18 patients (7 females and 11 males) classified as ASA I, adults and with normal body mass index, submitted to procedures in the anterior region (group I) and posterior region of the maxilla (group II). For 40 minutes, five 6 ml blood samples were collected every 10 minutes after infiltrative injection in each region of the maxil…
Bacteremia after diagnostic conventional laparoscopy and minilaparoscopy: a prospective study in 100 patients.
2006
Background/Goals: Diagnostic laparoscopy under sedoanalgesia is a valuable tool in the work-up of liver diseases and is helpful as a staging procedure. The rate of bacteremia caused by this procedure is unknown, in particular when performed as minilaparoscopy. Study: A 100 consecutive patients having undergone diagnostic laparoscopy carried out either conventionally (group I, n = 50) or as minilaparoscopy (group II, n - 50) were prospectively enrolled in this study. Blood cultures were drawn before and within 5 minutes after the procedure. Risk factors for bacteremia were evaluated. Results: Bacterial growth occurred in 4 blood cultures drawn immediately after laparoscopy. No patient develo…
Repetitive low-energy shock wave application without local anesthesia is more efficient than repetitive low-energy shock wave application with local …
2005
Background: It remains unclear whether application of local anesthesia (LA) interferes with clinical e!cacy of extracorporeal shock wave therapy (ESWT) for chronic plantar fasciitis. Aims: To evaluate the e"ect of local anesthesia on the clinical outcome after repetitive low-energy ESWT for chronic plantar fasciitis. Methods: Eighty-six patients with chronic plantar fasciitis were randomly assigned to receive either low-energy ESWT without LA, given weekly for three weeks (Group I, n = 45; 3 · 2000 pulses, total energy flux density per shock 0.09 mJ/mm 2 ) or identical ESWT with LA (Group II, n = 41). Primary outcome measure was: Reduction of pain from baseline to month 3 post-treatment in …
Standardized T2* map of normal human heart in vivo to correct T2* segmental artefacts.
2007
A segmental, multislice, multi-echo T2* MRI approach could be useful in heart iron-overloaded patients to account for heterogeneous iron distribution, demonstrated by histological studies. However, segmental T2* assessment in heart can be affected by the presence of geometrical and susceptibility artefacts, which can act on different segments in different ways. The aim of this study was to assess T2* value distribution in the left ventricle and to develop a correction procedure to compensate for artefactual variations in segmental analysis. MRI was performed in four groups of 22 subjects each: healthy subjects (I), controls (II) (thalassemia intermedia patients without iron overload), thala…
Type-IIA secreted phospholipase A2 is an endogenous antibiotic-like protein of the host.
2010
International audience; Type-IIA secreted phospholipase A(2) (sPLA(2)-IIA) has been proposed to play a role in the development of inflammatory diseases. It has been shown to release arachidonic acid, the precursor of proinflammatory eicosanoids, to hydrolyze phospholipids of pulmonary surfactant, and to bind to specific receptors located on cell surface membranes. However, the most established biological role of sPLA(2)-IIA is related to its potent bactericidal property in particular toward Gram-positive bacteria. This enzyme is present in animal and human biological fluids at concentrations sufficient to kill bacteria. Human recombinant sPLA(2)-IIA is able to kill Gram-positive bacteria at…
Évaluation des risques relatifs aux mesures de décontamination et de gestion des sous-produits animaux lors des cas de botulisme bovin et aviaire
2022
Le botulisme est une maladie neurologique humaine et animale, le plus souvent d’origine alimentaire, provoquée par l’action de neurotoxines bactériennes (toxines botuliques) produites par la bactérie Clostridium botulinum et qui se manifeste par une paralysie flasque pouvant aller jusqu’à la paralysie respiratoire et l’arrêt cardiaque. Neuf types toxiniques, répartis en une quarantaine de sous-types, sont actuellement connus.En France, le botulisme animal affecte essentiellement les oiseaux (sauvages et domestiques) et les bovins. Chez les volailles, on recense annuellement vingt à trente foyers, majoritairement dus aux types mosaïque C/D (élevages de poulets de chair et de dindes) suivi de…
Plasma concentration following oral and intramuscular atropine in children and their clinical effects.
1997
In a paediatric population, we compared i.m. v oral atropine premedication to a control group without atropine and determined atropine plasma concentrations (APC). Forty-five children were randomly assigned to one of three groups. Group I received atropine, 20 micrograms.kg-1 i.m., 15 min prior to induction. Group II received atropine, 30 micrograms.kg-1 orally, group III received no atropine. APC (expressed as percent of muscarine-2 receptor subtype occupancy), heart rate, rectal temperature, and salivation were determined before atropine, and 15, 25, 45, 60, 90, 120 (no APC), and 150 min following atropine. Only 10-20% of the M2-cholinoceptors were occupied after oral atropine with a peak…
