HPLC Determination of Polyphenols from Calendula officinalis L. Flowers
2017
Abstract Romanian spontaneous flora provides a lot of resources for the determination of different chemical compounds. This study uses flower samples from Calendula officinalis L. extracted through maceration. The chemical compounds determined were: (+)-catechin, caffeic acid, chlorogenic acid, cinnamic acid, ferulic acid, gallic acid, rutin, resveratrol and quercetin. They were analyzed by using an optimized HPLC method. (+)-Catechin, caffeic acid, chlorogenic acid and quercetin could not be identified in the analyzed samples. The greatest amount of phenolic compound found was rutin and the smallest quantity was determined for ferulic acid. The quantified compounds have proven to have bene…
Structural and Electrochemical Analysis of CIGS: Cr Crystalline Nanopowders and Thin Films Deposited onto ITO Substrates
2021
A new approach for the synthesis of nanopowders and thin films of CuInGaSe2 (CIGS) chalcopyrite material doped with different amounts of Cr is presented. The chalcopyrite material CuInxGa1 − xSe2 was doped using Cr to form a new doped chalcopyrite with the structure CuInxCryGa1 − x − ySe2, where x = 0.4 and y = 0.0, 0.1, 0.2, or 0.3. The electrical properties of CuInx CryGa1 − x − ySe2 are highly dependent on the Cr content and results show these materials as promising dopants for the fabrication thin film solar cells. The CIGS nano-precursor powder was initially synthesized via an autoclave method, and then converted into thin films over transparent substrates. Both crystalline precursor p…

References vielu izvēle polifenolu daudzuma aprēķināšanā ekvivalentos
2020
Polifenoliem ir labvēlīga ietekme uz cilvēka organismu. Tiem ir tādas funkcijas kā asinsrites uzlabošana, asinsvadu elastības uzturēšana, hronisku iekaisumu reakcijas mazināšana, brīvo radikāļu neitralizēšana, šūnu novecošanās aizkavēšana un daudzas citas. Daudzi no polifenolu izraisītiem veselības ieguvumiem var būt saistīti ar to antioksidantu lomu. Lai varētu izmērīt kopējo polifenolu daudzumu augu preparātos ir ieviesta references ekvivalentu pieeja. Šajā darbā piecu Vaccinium spp. ogu izpiedņu ekstraktos kopējais polifenolu daudzums tika izmērīts ar Folin-Čikolto metodi un aprēķināts gallu skābes, kvercetīna un rutīna ekvivalentos uz mg ekstrakta. Vislielāko daudzumu iegūst, rēķinot ga…
El gallego en la familia: entre la producción y la reproducción
2012
En este artículo abordamos el análisis de la evolución reciente del gallego en el ámbito familiar. En concreto, nos interesan los procesos de producción, reproducción y no reproducción de la lengua y sus consecuencias en la actual situación de substitución lingüística. En el periodo que va desde 1992 a 2008, la distribución de la lengua inicial se ha visto sensiblemente modificada, sobre todo por la penetración del español en la mayor parte de las familias. Sin embargo, el artículo pone de manifiesto los errores que plantea tomar la lengua inicial como única variable de referencia para medir la transmisión lingüística intergeneracional. Cuando esto se corrige, el análisis apunta a un notabl…
Instant kit preparation of 68Ga-radiopharmaceuticals via the hybrid chelator DATA: clinical translation of [68Ga]Ga-DATA-TOC
2019
Purpose The widespread use of 68Ga for positron emission tomography (PET) relies on the development of radiopharmaceutical precursors that can be radiolabelled and dispensed in a simple, quick, and convenient manner. The DATA (6-amino-1,4-diazapine-triacetate) scaffold represents a novel hybrid chelator architecture possessing both cyclic and acyclic character that may allow for facile access to 68Ga-labelled tracers in the clinic. We report the first bifunctional DATA chelator conjugated to [Tyr3]octreotide (TOC), a somatostatin subtype 2 receptor (SST2)-targeting vector for imaging and functional characterisation of SSTR2 expressing tumours. Methods The radiopharmaceutical precursor, DATA…
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…
