Horses Could Perceive Riding Differently Depending on the Way They Express Poor Welfare in the Stable

2020

International audience; This study investigated the relationships between four behavioral and postural indicators of a compromised welfare state in loose boxes (stereotypies, aggressive behaviors toward humans, withdrawn posture reflecting unresponsiveness to the environment, and alert posture indicating hypervigilance) and the way horses perceived riding. This perception was inferred using a survey completed by the usual riding instructor and during a standardized riding session (assessment of behaviors and postures, qualitative behavior assessment (QBA) and characterization of the horses' locomotion using an inertial measurement unit). In accordance with ear and tail positions and the QBA…

2021

COVID-19 epidemiological security measures – social service delivery disruption and restrictions on direct social contacts – stressed the need for transformations in social work practice. These res...

Design and synthesis of optical sensors for the detection of molecules with biological activity

2015

A la present tesi doctoral, titulada “Disseny i síntesi de sensors òptics per a la detecció de molècules amb activitat biològica”, s’han utilitzat diferents conceptes de la química supramolecular per a preparar compostos capaços de senyalitzar macroscópicament la presència de molècules tòxiques o actives biològicament. Així, s’han preparat quimio-sensors i quimiodosímetres per a la detecció d’anions, sals, zwitterions i agents de guerra química tal i com agents nerviosos i agents sanguinis. Addicionalment, es descriu el disseny i la construcció d’un aparell electrònic per a la monitorització automàtica d’aquests compostos. La tesi té un capítol introductori on s'expliquen els conceptes bàsi…

D vitamīna deficīts Latvijā salīdzinājumā ar citām valstīm un biežāk pielietotie principi tā novēršanai

2019

Vitamīna D nepietiekamība ir plaši izplatīta visā pasaulē. Veiktajā pētījumā tika analizētas „E.Gulbja laboratorijā” 02.01.2014.-31.12.2018. veikto vitamīna D asins analīžu rezultāti, un aptiekas klientu un ārstu anketēšanā iegūtā informācija. Pētījuma rezultāti liecina, ka 64% no visām veiktajām analīzēm tiek konstatēts vitamīna D trūkums. Novērošanas periodā konstatētais vidējais D vitamīna līmenis bija 27,5 ng/mL, kas, salīdzinājumā ar citām Eiropas valstīm, ir tuvu pietiekama līmeņa robežai. Vitamīna D līmeņa atjaunošanai iedzīvotāji 58,4% (n=59) veic pastaigas ārpus telpām, 55,4% (n=56) uzturā lieto ar vitamīnu D bagātu pārtiku, bet 36,6% (n=37) lieto vitamīnu D saturošus medikamentus …

SYNTHESIS AND ANTITUMOR ACTIVITY OF 2,5-BIS(3'-INDOLYL)-FURANS AND 3,5-BIS(3'-INDOLIY)-ISOXAZOLES, NORTOPSENTIN ANALOGUES

2010

Abstract A series of novel 2,5-bis(3′-indolyl)furans and 3,5-bis(3′-indolyl)isoxazoles were synthesized as antitumor agents. The antiproliferative activity was evaluated in vitro toward diverse human tumor cell lines. Initially 5 isoxazoles and 3 furan derivatives were tested against a panel of 10 human tumor cell lines and the most active derivatives 3c and 4a were selected to be evaluated in an extended panel of 29 cell lines. By exhibiting mean IC50 values of 17.4 μg/mL (3a) and 20.5 μg/mL (4c), in particular 4c showed a high level of tumor selectivity toward the 29 cell lines.

Pyrido[2’,3’:4,5]pyrrolo[2,1-d][1,2,3,5]tetrazine-4(3H)-ones, a new class of temozolomide heteroanalogues

2009

Twelve derivatives of new ring system pyrido[2’,3’:4,5]pyrrolo[2,1-d][1,2,3,5]tetrazine were prepared in good yields by reaction of 2-diazo-3-ethoxycarbonyl-pyrrolo[3,2-b]pyridine with alkyl- or aryl-isocyanates. Nine derivatives, screened by the National Cancer Institute (Bethesda, MD) for the in vitro one dose primary anticancer assay against a panel of about 60 human tumor cell lines, showed no significant activity.

SYNTHESIS OF 3-(2-PHENYL-1,3-THIAZOL-4-YL)-1H-INDOLES, NEW DERIVATIVES WITH POTENTIAL ANTINEOPLASTIC ACTIVITY

SYNTHESIS AND ANTIPROLIFERATIVE ACTIVITY OF 3-AMINO-N-PHENYL-1H-INDAZOLE-1-CARBOXAMIDES

2010

Recently our research group has reported the synthesis of some 3-amino-N-phenyl-1H-indazole-1-carboxamides able to inhibit at low micromolar concentrations the cell growth of many neoplastic cell lines. The above compounds are unsubstituted in the indazole nucleus and this gives the hope to obtain more active compounds if appropriate substituents are beared by the above nucleus. So, several new N-phenyl-1H-indazole-1-carboxamides 1c-h and 4l,m were prepared by reacting phenyl isocyanates 3a,b with 3-amino-1H-indazoles 2c,e,g, or 1H-indazole 2l respectively. Chemical trasformations of compounds 1a,b and 1g,h gave 3-acetamido-N-phenyl-1H-indazole-1-carboxamides 5a,b, and 3,5-diamino-N-phenyl-…

The chemical composition of the aerial parts essential oil of Lonas annua (L.) Vines & Druce (Asteraceae)

2022

Lonas annua (L.) Vines & Druce (Asteraceae), commonly known as African Daisy or Yellow Ageratum is a rare therophyte native to northwestern Africa (Algeria, Morocco, and Tunisia) and Italy (Sicily and Sardinia). In the present study, the chemical composition of the essential oil from aerial parts of Lonas annua was analyzed by GC-MS. No one report has been previously published on the essential oil of this species. The results showed the presence of large quantity of two unusual metabolites 2,3-dihydrofarnesol (41.64%), and acenaphthene (36.18%). Chemotaxonomic considerations were carried out in order to confirm the phylogenetic reconstructions of Anthemideae.
