Synthetic Polyclonal-Derived CDR Peptides as an Innovative Strategy in Glaucoma Therapy
2019
The pathogenesis of glaucoma is strongly associated with the occurrence of autoimmune-mediated loss of retinal ganglion cells (RGCs) and additionally, recent evidence shows that specific antibody-derived signature peptides are significantly differentially expressed in sera of primary-open angle glaucoma patients (POAG) compared to healthy controls. Synthetically antibody-derived peptides can modulate various effector functions of the immune system and act as antimicrobial or antiviral molecules. In an ex vivo adolescent glaucoma model, this study, for the first time, demonstrates that polyclonal-derived complementarity-determining regions (CDRs) can significantly increase the survival rate …
Synthesis and characterization of chalcogenide glasses from the system Ga-Ge-Sb-S and preparation of a single-mode fiber at 1.55 μm
2008
International audience; The aim of this work is to study different compositions in the Ga-Ge-Sb-S system for the definition of two compositions compatible with the elaboration of a single-mode fiber at the 1.55 μm telecom wavelength. The variations of the glass transition temperature (Tg), the dilatation coefficient (α) and the refractive index (n) have been studied for two glasses series: GaxGe25−xSb10S65 (series 1), Ga5Ge25−xSb10S60+x (series 2). This study has lead to the choice of the Ga4Ge21Sb10S65 composition as clad glass for the preparation of the single-mode fiber and Ga5Ge20Sb10S65 composition as the core. The discrepancies for the studied parameters between the core and clad comp…
Mitä oppilaat pitävät varhaisesta A1-kielen opetuksesta ja millainen käsitys heillä on omasta osaamisestaan?
2022
Vuoden 2020 alusta kieltenopiskelu on aloitettu Suomessa vuosiluokalla 1. Opetussuunnitelman perusteissa korostetaan, että opetuksen tulee olla ikätasolle sopivaa ja herättää myönteinen asenne kielenoppimiseen sekä vahvistaa oppilaan pystyvyyttä. Artikkelissa tarkastellaan suomen- ja ruotsinkielisten koulujen oppilaiden asennoitumista ja osaamiskäsityksiä. Tutkimuksen kohteen on englannin kielen (suomenkieliset koulut, n=106) ja suomi toisena kotimaisena kielenä -oppiaineen (ruotsinkieliset koulut, n=86) opiskelu. Tutkimus osoitti, että oppilaat pitivät pääosin niin opiskelemastaan kielestä kuin sen opiskelusta. He kokivat osaavansa tervehtimiseen, numeroihin ja väreihin liittyviä ilmaisuja…
Approche nutritionnelle de la thérapie du syndrome de l'œil sec : prévention par les acides gras polyinsaturés
2008
Dry eye disease affects 15% of the population over the age of 65. It is characterized mainly by inflammation of the ocular surface (tear film, conjunctiva and cornea) which represents a relevant target for therapeutic strategies. The side effects and long-term intolerance of anti-inflammatory drugs give rise to an increasing interest for dietary components exhibiting anti-inflammatory properties, such as polyunsaturated fatty acids (PUFAs). In these studies, we developed a scopolamine-induced dry eye model in the rat that mimics changes occurring in Humans suffering from moderate dry eye. We described the time course of clinical signs, inflammation and mucin production loss. We investigated…
Abundance of narG , nirS , nirK , and nosZ Genes of Denitrifying Bacteria during Primary Successions of a Glacier Foreland
2006
ABSTRACT Quantitative PCR of denitrification genes encoding the nitrate, nitrite, and nitrous oxide reductases was used to study denitrifiers across a glacier foreland. Environmental samples collected at different distances from a receding glacier contained amounts of 16S rRNA target molecules ranging from 4.9 × 10 5 to 8.9 × 10 5 copies per nanogram of DNA but smaller amounts of narG , nirK , and nosZ target molecules. Thus, numbers of narG , nirK , nirS , and nosZ copies per nanogram of DNA ranged from 2.1 × 10 3 to 2.6 × 10 4 , 7.4 × 10 2 to 1.4 × 10 3 , 2.5 × 10 2 to 6.4 × 10 3 , and 1.2 × 10 3 to 5.5 × 10 3 , respectively. The densities of 16S rRNA genes per gram of soil increased with…
Petrography and carbonate isotope stratigraphy from MIS AND-1B core, Antarctica: Evidence of the early Pliocene warming event
2011
Abstract A large portion of ANDRILL (ANtarctic geological DRILLing) core AND-1B recovered in the Western Ross Sea and spanning the early Pliocene has been investigated in order to obtain a detailed carbonate isotope record from Antarctic margin sediments through the early Pliocene warming event. Petrographic observations and mineralogical analyses reveal the authigenic nature of the carbonate and small proportions of Fe and Mg incorporated within the calcite lattice. High productivity conditions testified by ~ 80 m-thick diatomite interval (383 to 460 mbsf) well fit with the composite nature of the authigenic carbonate generally characterizing organic matter-rich sediments. As is known, sed…
