Abstract:

A direct injection high efficiency nebulizer (DIHEN) and a large-bore DIHEN (LB-DIHEN) are investigated for the determination of difficult-to-analyze and memory-prone elements (mercury, iodine, and boron). The determination of such elements is problematic using conventional sample introduction systems incorporating spray chambers and/or desolvation devices owing to their large surface area and hence long wash-out characteristics. With the DIHEN or LB-DIHEN, the spray chamber is eliminated and the dead volume is reduced to <10 μL, thus reducing memory effects. In comparison with the crossflo

Abstract:

A novel method for the determination of chromium in suspensions of human lung fibroblast cells is described by using a large bore–direct injection high efficiency nebulizer (LB-DIHEN) with micro-scale flow injection analysis and inductively coupled plasma mass spectrometric detection. Chromium(VI)-treated cells were first counted and then suspended in a phosphate buffer saline solution. With the use of the method of standard additions, the relative concentration of Cr in ∼ 100 HLF cells/peak was determined at m/z = 50. Because the cells tend to clump and can yield inhomogeneities in the total

Abstract:

AbstractA microchip-based capillary electrophoresis (µCE) system was interfaced with a microwave induced plasma optical emission spectrometry (MIP-OES) to provide copper species separation capabilities. This system uses an extremely low flow demountable direct injection high efficiency nebulizer (D-DIHEN) sited directly at the liquid exit of the chip. A supplementary flow of buffer solution at the channel exit was used to improve nebulization efficiency. A small evaporation chamber has been incorporated into the interface in order to prevent the losses associated with traditional spray chamber

This was carried out via CID and ion–molecule reactions (IMR) of [Pt(dien)N]+ in the gas phase. Labelling studies (15N and 2H labelling of the dien ligand) were also employed. As a result, some of the previously proposed structures were ruled out and three other potential structures of [Pt(dien)N]+ are considered. Labelling studies a

In the current study, we first confirmed the anti-inflammatory effect of 7S,15R-dihydroxy-16S,17S-epoxy-docosapentaenoic acid (diHEP-DPA), a novel DHA dihydroxy derivative synthesized in our previous work.

Abstract:

Koordinazio-polimero luminiszenteak aurreko mendetik ezagutzen diren arren, izugarrizko hazkundea izan dute aurreko hamarkadatik gaur egun arte, erakusten duten argi-igorpen gaitasun paregabeei esker. Material horiekin, gailu argitsuen arloan belaunaldi berri bat garatzen hasi da, bereziki sentsore gisa edo faltsifikazio-sistemetan erabiltzeko. Material hauen aplikazio gehienek intentsitate handiko igorpenak edota igorpen iraunkorrak izatera behartzen dute. Zentzu horretan, koordinazio-polimeroak aukera egokiak dira, beren izaera metal-organikoa dela eta; haien egitura kristalinoa nahi diren p

Mikrotxipak, besteak beste, itu organismo, ehun edo zelulen artean ematen diren transkriptoma mailako ezberdintasunak ikertzeko diseinatu dira. Emaitza gisa, faktore estresatzaile ezberdinen jokatzeko modua edo jarraibidea itsas organismoetan modu zabalean ikertzea lortu da. Horrela, lan honen helburu nagusiak, batetik, teleosteotan ingurune urtarretan ohikoak diren sustantzia kimikoen ekiteko modua aztertzen duten mikrotxipak laburbiltzea da; eta bestetik, mikrotxipen inguruan dauden kritikak azaltzea.

Abstract:

Currently, the use of synthetic pesticides is the main method of plant protection applied in agri- and horticulture. However, its excessive use leads to the development of pesticide resistance, a contamination of the environment, toxicity to non-target organisms, and risks for human health. With the ultimate aim of contributing to the develop of a more sustainable pest management, we used the natural product germacrone (compound 1), reported to possess significant insecticidal activity, as starting material for the generation of molecular diversity (2–24).

Human biliary tree stem/progenitor cells (hBTSCs), reside in peribiliary glands, are mainly stimulated by primary sclerosing cholangitis (PSC) and cholangiocarcinoma. In these pathologies, hBTSCs displayed epithelial-to-mesenchymal transition (EMT), senescence characteristics, and impaired differentiation. Here, we investigated the effects of cholest-4,6-dien-3-one, an oxysterol involved in cholangiopathies, on hBTSCs biology. hBTSCs were isolated from donor organs, cultured in self-renewal control conditions, differentiated in mature cholangiocytes by specifically tailored medium, or exposed

Abstract:

This study analyzes the patterns of incorporation of English elements in New Mexican Spanish in the decades following the annexation of New Mexico by the United States as reflected in a corpus of private letters written between 1848 and 1936. The quantitative analysis shows that most types of contact features are infrequent during much of this period, but there is an increase in the presence of English elements in the last decades covered by the corpus. It also shows that semantic and lexical borrowing is much more frequent than structural interference or code-switching. These findings are the
