Associative behaviour of κ-carrageenan in aqueous solutions and its modification by different monovalent salts as reflected by viscometric parameters
2019
Abstract The viscometric behaviour of κ-carrageenan in aqueous solutions and in the presence of monovalent salts was investigated at 25 °C. Coil, helix or double helix conformations were induced by cooling hot κ-carrageenan solutions under appropriate ionic conditions. A new viscometric approach was used for modeling the behaviour of κ-carrageenan solutions. The intrinsic viscosity, [η], is markedly changed by the presence of different monovalent salts (NaCl, NaI and CsI). In pure water, the intrinsic viscosity amounts to 48 dL·g−1. In 0.1 M NaCl solutions (single helix state) [η] is 6.2 dL·g−1, whereas in 0.1 M NaI (double helix conformation) it is approximately twice as large. In 0.1 M Cs…
Rosyjski korpus posiłkowy (auksyliarny) na służbie Augusta II w Rzeczypospolitej i Saksonii. Nowe spojrzenie na sasko-polsko-rosyjską współpracę poli…
2019
Polityczno-militarna współpraca sasko-polsko-rosyjska od początku wielkiej wojny północnej (1700–1721) nie układała się po myśli Augusta II, który ponosił klęski w starciach z wojskami Karola XII i po przegranej Piotra I pod Narwą w 1700 roku wziął na siebie główny ciężar wojny. Próbą wspomożenia armii saskiej Augusta II przez cara, który obawiał się zawarcia przez władcę sasko-polskiego separatystycznego pokoju z królem szwedzkim, i chciał także zaangażowania w konflikt Rzeczypospolitej, było zorganizowanie rosyjskiego korpusu posiłkowego (auksyliarnego), który z perspektywy czasu okazał się zabiegiem politycznym, a w mniejszym stopniu wojskowym. W zaprezentowanym artykule recenzyjnym prob…
Plasma cell-free DNA in diagnostic KRAS mutation testing
2015
Epidermaalisen kasvutekijän reseptorin (EGFR) monoklonaalisia vasta-aineita (mAb) käytetään apuna metastaattisen kolorektaalisyövän (mCRC) hoidossa. Aktivoivat mutaatiot KRAS- ja NRAS-onkogeeneissä tekevät syöpäsolut vastustuskykyisiksi anti-EGFR-vasta-aineille, ja tästä syystä tuumorit tulee genotyypittää ennen hoidon aloittamista. Kudosbiopsian ottaminen on kuitenkin invasiivinen toimenpide, eikä näyte välttämättä edusta kattavasti syövän kaikkien solupopulaatioiden geneettisiä muutoksia. Verenkierron solunulkoisen DNA:n (cfDNA) on havaittu sisältävän maligneista soluista lähtöisin olevia onkogeenisiä mutaatioita, ja se voi olla hyvä vaihtoehtoinen tuumoriperäisen DNA:n lähde. Kehitimme j…
Relation between structural and release properties in a polysaccharide gel system.
2007
Abstract The potential utility of κ-carrageenan gels for preparing drug release devices is here shown. Structural properties of κ-carrageenan gels prepared with different salt composition and containing Ketoprofen sodium salt, as model drug, have been evaluated with static light scattering and rheological measurements. These properties have been correlated with release profiles in vitro at pH 5.5. Release properties from gelled matrices have been compared with those obtained by two commercial products containing the same drug. Results show that: i) in this system it is possible to easily control the gel texture by using different cationic concentration; ii) the kinetics of drug release by κ…
Catacomba di Villagrazia di Carini. Il cubicolo X20. Ricerche 2008-2013
2014
Il X20 è uno dei cubicoli più rilevanti della galleria X. Consiste in una camera funeraria quadrangolare di m 8 (E-O) x 5 (N-S), preceduta da un dromos quadrato di m 1,80 x 1,80 e derivata da un preesistente arcosolio bisomo. La camera accoglie in tutto ventinove sepolture: dodici arcosoli sia per adulti che per bambini, una tomba a nicchia, due tombe a cassa e quattordici formae. I dati archeologici e gli esiti dell’analisi strutturale hanno permesso di accertare che l’attuale aspetto del cubicolo è il risultato di quattro fasi costruttive. Nella prima fase (IV.a) l’ambiente è a pianta quadrata (m 3,56 x 3,56), con arcosoli per bambini nel dromos e sulla parete nord; una decorazione ad aff…

Repeated exposure of fluazinam fungicides affects gene expression profiles yet carries no costs on a nontarget pest
2021
Fungicides are used to control pathogenic fungi of crop species, but they have also been shown to alter behavioral, life history and fitness related traits of non-target insects. Here, we tested the fungicide effects on feeding behavior, survival and physiology of the non-target pest insect, the Colorado potato beetle (Leptinotarsa decemlineata). Feeding behavior was studied by a choice test of adult beetles, which were allowed to choose between a control and a fungicide (fluazinam) treated potato leaf. Larval survival was recorded after 24-hour and 72-hour exposure to control and fungicide-treated leaves with two different concentrations. The adults did not show fungicide avoidance behavio…
Isolation of two triterpenoids and a biflavanone with anti-Inflammatory activity from Schinus molle fruits.
2003
Three compounds with anti-inflammatory activity were isolated from Schinus molle fruits. Two of the compounds were identified as 3- epi-isomasticadienolalic acid ( 1), isomasticadienonalic acid ( 2) and chamaejasmin ( 3). Triterpenes 1 and 2, and biflavanone 3 were tested on two models of mice paw inflammation: one of acute inflammation, induced by subcutaneous injection of either phospholipase A (2) (PLA (2)) or carrageenan in the paws of mice, and one of chronic inflammation in the form of eczema, provoked by repeated administration of TPA to the ears of mice. On the PLA (2)-induced mouse paw oedema, only 2 was active (30 mg/kg, 66 % inhibition at 60 min), whereas all compounds reduced th…
Carbon’s Three-Center-Four-Electron Tetrel Bond, Treated Experimentally
2018
Tetrel bonding is the noncovalent interaction of group IV elements with electron donors. It is a weak, directional interaction that resembles hydrogen and halogen bonding yet remains barely explored. Herein, we present an experimental investigation of the carbon-centered, three-center, four-electron tetrel bond, [N−C− N]+ , formed by capturing a carbenium ion with a bidentate Lewis base. NMRspectroscopic, titration-calorimetric, and reaction-kinetic evidence for the existence and structure of this species is reported. The studied interaction is by far the strongest tetrel bond reported so far and is discussed in comparison with the analogous halogen bond. The necessity of the involvement of…
Photosensitive Alternative Splicing of the Circadian Clock Gene timeless Is Population Specific in a Cold-Adapted Fly, Drosophila montana.
2018
To function properly, organisms must adjust their physiology, behavior and metabolism in response to a suite of varying environmental conditions. One of the central regulators of these changes is organisms' internal circadian clock, and recent evidence has suggested that the clock genes are also important in the regulation of seasonal adjustments. In particular, thermosensitive splicing of the core clock gene <i>timeless</i> in a cosmopolitan fly, <i>Drosophila melanogaster</i> , has implicated this gene to be involved in thermal adaptation. To further investigate this link we examined the splicing of <i>timeless</i> in a northern malt fly species, <i&…
