Antinociceptive Effects of Turkish Endemic Eryngium kotschyi Boiss. Roots by Bioactivity Guided Fractionation
2010
Eryngium species (Apiaceae) are well known plants in ethnobotanical culture throughout world and also in Turkey. They are used as antitussive, diuretic as well as for analgesic and antiinflammatory purposes in traditional medicine. This study aimed to evaluate the antinociceptive activity of endemic Eryngium kotschyi Boiss. root extracts by bioguided fractionation. The antinociceptive activity of the extracts/fractions/compound was studied in mice using acetic acid induced writhing test and and hot plate test. The methanolic extract was sequentially partitioned with hexane, dichloromethane and water saturated n-butanol. Among the fractions, the n-BuOH fraction showed the most significant re…
Chemical Composition of the Essential Oil of Teucrium flavum ssp. flavum from Zakynthos, Greece
2012
Essential oil extracted from dried aerial parts of Teucrium flavum ssp. flavum harvested in Zakynthos, Greece, was analysed by gas phase chomatography (GC) and gas chomatography mass spectrometry (GC-MS). The main constituents were caryophyllene (13.5%), caryophyllene oxide (8.5%), 4-vinyl guaiacol (6.0%) and α- humulene (5.0%).

Expériences croisées face à l’épreuve de la maladie d’Alzheimer. Quand personnes malades et proches dessinent des trajectoires d’accompagnement contr…
2018
Cadre de recherche : La littérature consacrée aux familles des personnes malades d’Alzheimer met en lumière la charge que peut représenter l’accompagnement d’une personne malade, mais aussi la diversité des expériences vécues par les proches. Malgré l’abondance de littérature, deux limites sont constatées : ces travaux se fondent strictement sur le discours des proches et ils appréhendent l’expérience de l’accompagnement sur la base d’une approche synchronique.Objectifs : Cet article a l’ambition de dépasser ces deux limites en mettant en dialogue, dans la durée, les témoignages des personnes malades d’Alzheimer et de leurs proches. Nous proposons d’analyser ce qui se joue dans les dynamiqu…

Evaluation of the inverse electron demand Diels-Alder reaction in rats using a scandium-44-labelled tetrazine for pretargeted PET imaging
2019
Background Pretargeted imaging allows the use of short-lived radionuclides when imaging the accumulation of slow clearing targeting agents such as antibodies. The biotin-(strept)avidin and the bispecific antibody-hapten interactions have been applied in clinical pretargeting studies; unfortunately, these systems led to immunogenic responses in patients. The inverse electron demand Diels-Alder (IEDDA) reaction between a radiolabelled tetrazine (Tz) and a trans-cyclooctene (TCO)-functionalized targeting vector is a promising alternative for clinical pretargeted imaging due to its fast reaction kinetics. This strategy was first applied in nuclear medicine using an 111In-labelled Tz to image TC…
Labeling of DOTA-conjugated HPMA-based polymers with trivalent metallic radionuclides for molecular imaging.
2017
Background In this work, the in vitro and in vivo stabilities and the pharmacology of HPMA-made homopolymers were studied by means of radiometal-labeled derivatives. Aiming to identify the fewer amount and the optimal DOTA-linker structure that provides quantitative labeling yields, diverse DOTA-linker systems were conjugated in different amounts to HPMA homopolymers to coordinate trivalent radiometals Me(III)* = gallium-68, scandium-44, and lutetium-177. Results Short linkers and as low as 1.6% DOTA were enough to obtain labeling yields > 90%. Alkoxy linkers generally exhibited lower labeling yields than alkane analogues despite of similar chain length and DOTA incorporation rate. High sta…
