Apolar versus polar solvents: a comparison of the strength of some organic acids against different bases in toluene and in water

2010

The constants of ion-pair formation with 3-nitroaniline (3NO(2)A) for eight halogenoacetic acids (HAAs, 3a-h: TFA, TCA, TBA, DFA, DCA, DBA, MCA, and MBA), and five 2,2-dichloroalkanoic acids containing 3-8 carbon atoms (HAs, 5a-e: DCPA, DCBA, DCMBA, DCVA, and DCOA) have been determined in TOL at 298.1 K. The results obtained brought to evidence for HAAs the formation of ion-pairs with two different stoichiometries (base-acid, 1:1 or 1:2), while in contrast the HAs furnish only the 1:1 pairs. The different steric and electronic requirements of HAAs and HAs seem to be responsible for such an unlikely behavior. At the same time, the acid-catalyzed MRH of the (Z)-phenylhydrazone of 5-amino-3-be…

Nitrofurāna atvasinājuma medikamentu aprite SIA "Latvijas aptieka - 1" 2014. un 2015. gadā

2016

Urīnceļu infekcijas kontrolei izmanto galvenokārt nitrofurānu grupas preparātus, kuru indikācijas ir ne tikai urīnizvadceļu infekciju terapija, bet ir pierādīts arī šo preparātu efekts, pielietojot tos profilakses nolūkā. Darba mērķis ir noskaidrot nitrofurāna atvasinājuma grupas medikamentu lietošanas tendences pacientu pieredzi, lietojot šos medikamentus un farmaceitu pieredzi attiecībā par šo medikamentu izsniegšanas procesā gūtajiem novērojumiem. Lai sasniegtu izvirzīto mērķi, tika veikta aptiekā atprečoto recepšu datu apstrāde un analīze par 2014. un 2015. gadu. Autore objektīvākam rezultātu izvērtējumam veikusi arī aptiekas klientu un aptiekā strādājošo farmaceitu aptauju. Aptauju rez…

Crystal structure of trans-di­chloridobis­[N-(5,5-di­methyl-4,5-di­hydro-3H-pyrrol-2-yl-κN)acetamide]palladium(II) dihydrate

2017

The title complex, [PdCl2(C8H14N2O)2]2H2O, was obtained by N–O bond cleavage of the oxadiazoline rings of the trans-[dichlorido-bis(2,5,5-trimethyl- 5,6,7,7a-tetrahydropyrrolo[1,2-b][1,2,4]oxadiazole-N1 )]palladium(II) complex. The palladium(II) atom exhibits an almost square-planar coordination provided by two trans-arranged chloride anions and a nitrogen atom from each of the two neutral organic ligands. In the crystal, N—HO, O—HO and O—HCl hydrogen bonds link complex molecules into double layers parallel to the bc plane. peerReviewed

Diels–Alder reaction of β-fluoro-β-nitrostyrenes with cyclic dienes

2021

The Diels–Alder reaction of β-fluoro-β-nitrostyrenes with cyclic 1,3-dienes was investigated. A series of novel monofluorinated norbornenes was prepared in up to 97% yield. The reaction with 1,3-cyclohexadiene permits the preparation of monofluorinated bicyclo[2.2.2]oct-2-enes. The kinetic data of the reactions with 1,3-cyclopentadiene and 1,3-cyclohexadiene were used to calculate activation parameters. Furthermore, the synthetic utility of the cycloadducts obtained was demonstrated.

Role of the NF-kB pathway and nitric oxide in mammary gland involution after weaning. Implications in breast cancer

2013

INTRODUCCIÓN La glándula mamaria es un órgano dinámico que alcanza su máximo desarrollo funcional con la lactancia, momento en el cual, a través de la producción de leche, aporta nutrientes y protección inmunológica a las crías de los mamíferos. Cuando la lactancia finaliza con el destete, el exceso de tejido glandular debe desaparecer y la glándula sufre una extensa remodelación hasta alcanzar nuevamente un estado pre-gestacional, preparada para un nuevo ciclo. La involución del tejido mamario es un proceso complejo durante el cual se suceden de forma coordinada una serie de eventos como la muerte de las células epiteliales secretoras, la proliferación de tejido adiposo circundante y la re…

The interactive effects of various nitrogen fertiliser formulations applied to urine patches on nitrous oxide emissions in grassland

2017

AbstractPasture-based livestock agriculture is a major source of greenhouse gas (GHG) nitrous oxide (N2O). Although a body of research is available on the effect of urine patch N or fertiliser N on N2O emissions, limited data is available on the effect of fertiliser N applied to patches of urinary N, which can cover up to a fifth of the yearly grazed area. This study investigated whether the sum of N2O emissions from urine and a range of N fertilisers, calcium ammonium nitrate (CAN) or urea ± urease inhibitor ± nitrification inhibitor, applied alone (disaggregated and re-aggregated) approximated the N2O emission of urine and fertiliser N applied together (aggregated). Application of fertili…

Prenatal air pollution exposure and growth and cardio-metabolic risk in preschoolers

2020

Objectives: We investigated the association between outdoor air pollutants exposure in the first trimester of pregnancy, and growth and cardio-metabolic risk at four years of age, and evaluated the mediating role of birth weight. Methods: We included mother-child pairs (N = 1,724) from the Spanish INMA birth cohort established in 2003-2008. First trimester of pregnancy nitrogen dioxide (NO2) and fine particles (PM2.5) exposure levels were estimated. Height, weight, waist circumference, blood pressure, and lipids were measured at four years of age. Body mass index (BMI) trajectories from birth to four years were identified. Results: Increased PM2.5 exposure in the first trimester of pregnanc…
