Synthesis and biological evaluation of novel peptidomimetics as rhodesain inhibitors
2016
Novel rhodesain inhibitors were developed by combining an enantiomerically pure 3-bromoisoxazoline warhead with a 1,4-benzodiazepine scaffold as specific recognition moiety. All compounds were proven to inhibit rhodesain with Ki values in the low-micromolar range. Their activity towards rhodesain was found to be coupled to an in vitro antitrypanosomal activity, with IC50 values ranging from the mid-micromolar to a low-micromolar value for the most active rhodesain inhibitor (R,S,S)-3. All compounds showed a good selectivity against the target enzyme since all of them were proven to be poor inhibitors of human cathepsin L. Novel rhodesain inhibitors were developed by combining an enantiomeri…
Cryopreservation of Hazelnut (Corylus avellana L.) Axillary Buds from In Vitro Shoots Using the Droplet Vitrification Method
2021
Cryopreservation by droplet vitrification was applied to hazelnut (Corylus avellana L.). axillary buds of the Italian cultivated variety Tonda Gentile Romana, which were collected from in vitro growing shoots, immersed in ice cooled PVS2 or PVS3 for 60 or 90 min, then transferred to a droplet of vitrification solution, placed on a strip of aluminium foil, and plunged into liquid nitrogen (LN). Additionally, the effect on the recovery of the mother plant after cryopreservation was evaluated, following a cold pre-treatment at 4 °C for 3 months. The highest regrowth percentage (56.7%) was obtained after applying PVS3 for 60 min, while the application of PVS2 for the same amount of time reduced…

Efectos de un programa de intervención psicoeducativa en la calidad de vida de los/las pacientes durante sus tratamientos de Reproducción Asistida
2021
El término Infertilidad Humana se refiere a la no consecución del embarazo después de 12 meses de mantener relaciones sexuales sin el uso de métodos anticonceptivos. Ha sido reconocido por la Organización Mundial de la Salud (OMS) como un problema de salud pública a nivel global, y aunque existe un alto número de personas con infertilidad, aproximadamente tan sólo la mitad de estas personas buscan tratamientos médicos para lograr concebir. Las personas que se someten a Tratamientos de Reproducción Asistida (TRA) pasan por una serie de etapas en las que sufren distintos tipos de cambios, tanto en su estado físico como emocional. La literatura muestra que durante los tratamientos las mujeres …

Optical quality of hyperopic and myopic phakic intraocular lenses
2013
Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…
Drought Stress Study on Nicotiana tabacum L., “Baladi”, an In Vitro Experimental Model
2021
Crops drought tolerance is a trait of outmost importance for agriculture especially today when climate change is affecting more the production for food and feed. The scope of this article is to evaluate in vitro drought stress response of Nicotiana tabacum L., “Baladi”. The experiment was set up for four successive stages starting with in vitro seedling development, hypocotyl cultivation, three generations of micropropagation, pre-acclimatization and acclimatization. The effect of abscisic acid (ABA) and/or polyethylene-glycol 6000 (PEG) on tobacco hypocotyl caulogenesis and micropropagation were investigated. Superoxide-dismutases (SODs) and peroxidases (POXs) are more active and different…
Water-Soluble Cuprizone Derivative: Synthesis, Characterization, and in Vitro Studies
2019
The cuprizone mouse model is one of the most accepted model systems for the investigation of oligodendrocyte degeneration, a process critically involved in the pathogenesis of diseases such as multiple sclerosis or schizophrenia. In order to substitute the in vivo experiments by in vitro approaches, the amine derivative BiMPi is introduced as a water-soluble alternative to cuprizone. Regarding superoxide dismutase activity, toxicity for oligodendrocytes, and disturbance of mitochondrial membrane potential, BiMPi shows similar in vitro effects as is observed in vivo for cuprizone. peerReviewed
No Dracocephalum ruyschiana L. iegūtu bioloģiski aktīvo vielu ādu balinošo īpašību novērtējums in vitro
2016
Darba mērķis bija novērtēt no Ruiša pūķgalves savvaļas augiem un in vitro dzinumu kultūrām iegūtu bioloģiski aktīvos savienojumus saturošu ekstraktu ādu balinošās īpašības, izmantojot in vitro testēšanas metodes. Ruiša pūķgalves in vitro ekstrakta drošība tā pielietojumam kosmētikas preparātos tika noteikta, pārbaudot tā ietekmi uz dažādu ādas tipu šūnu proliferāciju un morfoloģiju. Ādu balinošā potenciāla novērtēšanai tika izmantots sēņu tirozināzes inhibīcijas tests un cilvēka ādas melanomas šūnu in vitro modelis. No Ruiša pūķgalves in vitro dzinumu kultūras tika iegūts savvaļas augam līdzvērtīgs un lietošanai drošs ekstrakts, kas inhibēja sēņu un šūnu tirozināzes aktivitāti, bet būtisiki…
