What is driving the decision to perform filtering surgery in glaucoma patients?
2015
Purpose: To assess what is driving the decision to perform a filtering procedure in glaucoma patients. Methods: Retrospective study in one single University center. All the indications for filtering glaucoma surgeries (alone or combined with cataract extraction) performed in 2013 by the same surgeon were reviewed. The indications were as follows: clinical evaluation of the optic disc, visual field progression, progression on imaging (OCT), poor tolerance to medical treatment, poor control of intraocular pressure (IOP) and cataract. Results: The filtering surgeries (n = 159) were as follows: 78 trabeculectomies, 45 combined cataract and deep sclerectomy, 24 combined cataract and trabeculecto…

Time course of IOP elevation, electroretinographic changes and retinal ganglion cell loss in a rat model of glaucoma induced by laser
2007
International audience; Purpose: To evaluate the time course of intraocular pressure (IOP) elevation, electroretinographic changes and retinal ganglion cell (RGC) loss in a rat model of glaucoma induced by photocoagulation of the trabeculum and the episcleral and limbal veins. Methods: Male Sprague Dawley rats were used at 6 weeks of age. At least 3 of the episcleral veins, the trabeculum and the limbal veins were photocoagulated with a laser at 532nm (Quantel Medical, Vitra) in one eye of the animals. IOP and electroretinogram (ERG) were monitored every 2 weeks during 11 weeks after photocoagulation. Three months after laser photocoagulation, the RGC population was identified with a 5% Flu…
Plasmalogens in the pathogenesis of glaucomatous optic neuropathy
2011
Neuronal tissues such as the retina contain high amounts of plasmalogens. One of their particularities is to concentrate polyunsaturated fatty acids (PUFA) before releasing them specifically. Several data from our laboratory suggest that plasmalogens are involved in the pathophysiology of primary open angle glaucoma (POAG), the second leading cause of blindness worldwide. The different experiments were carried out on human patients with POAG as well as on rodent models of glaucoma. They concerned either the identification of specific alterations of plasmalogen metabolism, or the efficacy of PUFAs to prevent retinal damage. The results have shown a loss of several circulating plasmalogens in…
Etude du rôle de STING dans la biologie des lymphocytes T CD4 : application en immunothérapie anticancéreuse
2021
Recognition of danger signals by intracellular or extracellular receptors expressed by innate immune cells is crucial for the establishment of an effective adaptive immune response. STING (Stimulator of Interferon Genes) is a protein located in the endoplasmic reticulum discovered in 2008 as being essential for the detection of cytosolic DNAs and the establishment of antiviral immune response mediated by type I interferons (IFNs). The STING protein also plays a key role in spontaneous anti-tumor immune responses and the administration of STING ligands in tumor-bearing mice favors tumor growth control. These observations have been verified in clinical trials in patients with melanoma, illust…
Typology of exogenous organic matters based on chemical and biochemical composition to predict potential nitrogen mineralization
2010
Our aim was to develop a typology predicting potential N availability of exogenous organic matters (EOMs) in soil based on their chemical characteristics. A database of 273 EOMs was constructed including analytical data of biochemical fractionation, organic C and N, and results of N mineralization during incubation of soil–EOM mixtures in controlled conditions. Multiple factor analysis and hierarchical classification were performed to gather EOMs with similar composition and N mineralization behavior. A typology was then defined using composition criteria to predict potential N mineralization. Six classes of EOM potential N mineralization in soil were defined, from high potential N minerali…
