Insecticidal Activity and Synergistic Combinations of Ten Different Bt Toxins against Mythimna separata (Walker)
2018
The oriental armyworm (OAW), Mythimna separata (Walker), is a destructive pest of agricultural crops in Asia and Australia. Commercialized Bt crops have performed very well against their target pests
Redox regulation of genome stability by effects on gene expression, epigenetic pathways and DNA damage/repair
2015
Reactive oxygen and nitrogen species (e.g. H2O2, nitric oxide) confer redox regulation of essential cellular signaling pathways such as cell differentiation, proliferation, migration and apoptosis. In addition, classical regulation of gene expression or activity, including gene transcription to RNA followed by translation to the protein level, by transcription factors (e.g. NF-κB, HIF-1α) and mRNA binding proteins (e.g. GAPDH, HuR) is subject to redox regulation. This review will give an update of recent discoveries in this field, and specifically highlight the impact of reactive oxygen and nitrogen species on DNA repair systems that contribute to genomic stability. Emphasis will be placed …
Antimicrobial peptides from echinoderms as antibiofilm agents: a natural strategy to combat bacterial infections
2014
AbstractIncreased attention has been focused on marine invertebrates as a source of bioactive molecules for biomedical applications. Many bioactive molecules are part of the innate immune system. Some more recently isolated compounds, mainly from the sea urchin and the sea cucumber, are antimicrobial peptides (AMPs) active against Gram-positive and Gram-negative bacteria, and fungi. In this review we described the most recent studies on AMPs isolated from echinoderms. AMPs are small peptides (< 10 kDa) with cationic charge and amphipathic structure. Recently, it was demonstrated that in the coelomocyte lysates of Paracentrotus lividus and Holothuria tubulosa, AMPs possess activity against s…
Ks. Franz Urban (1832-1908) – ojciec cecylianizmu na ziemi kłodzkiej
2012
Wiek XIX, a zwłaszcza jego druga połowa, zaznaczył się w dziejach katolickiej muzyki kościelnej intensywnym ruchem odnowy (reforma cecyliańska). Ojcem tego ruchu na ziemi kłodzkiej był ks. Franz Urban, który już w 1869 roku założył w Lądku-Zdroju pierwsze koło cecyliańskie. W 1873 roku przekształciło się ono w Stowarzyszenie Cecyliańskie Hrabstwa Kłodzkiego i działało na rzecz poprawy stanu muzyki kościelnej aż do 1945 roku. W latach 1884–1902 funkcję prezesa tego związku pełnił ks. Franz Urban. Urodził się 6 stycznia 1832 roku w Wambierzycach. Po ukończeniu Gimnazjum Katolickiego w Kłodzku rozpoczął we Wrocławiu studia teologiczne. Święcenia kapłańskie przyjął 30 czerwca 1857 roku. Następn…

Naturally occurring hemolysins in the coelomic fluid of Holothuria polii delle chiaie (Echinodermata).
1979
Abstract The coelomic fluid of Holothuria polii D.Ch contains hemolytic activity against erythrocytes of several vertebrate species. The hemolytic potency depends upon calcium ion concentration and varies according to erythrocyte source and cell number in the reaction mixture. Absorption experiments with formalinized rabbit erythrocytes suggest that hemolytic activity is not specific. Its heat lability, water insolubility at low pH values, and sensitivity to proteolytic enzymes suggest that hemolytic activity resides in protein molecules. The activity, maximal in alkaline media, appears to depend up time and temperature.
Oltre la ricerca del Graal, il divenire del mito
2014
A mythologist's study of the Graal cultural tradition. Using Francesco Zambon's recent Metamorfosi del Graal as his starting point, the author undertakes an analysis on the importance of the Graal in Western mystical, philosophical and literary traditions throughout time, from the impact of the medieval Graal stories on the matière de Bretagne and beyond (Troyes, Boron), to the appeal of this myth in modern times, including its occurrence on Richard Wagner, Martin Heidegger, Simone Weil, Italo Calvino and Umberto Eco.
Functional significance of membrane associated proteolysis in the toxicity of Bacillus thuringiensis Cry3Aa toxin against Colorado potato beetle.
2012
Abstract Bacillus thuringiensis Cry toxins are widely used as biocontrol agents in bioinsecticides and transgenic plants. In the three domain-Cry toxins, domain II has been identified as an important determinant of their highly specific activity against insects. In this work, we assessed the role in membrane associated proteolysis and toxicity in Colorado potato beetle (CPB) of a previously reported ADAM recognition motif present in Cry3Aa toxin domain II. We used site-directed mutagenesis to modify the Bacillus thuringiensis cry3A gene in amino acid residues 344, 346, 347, 351 and 353 of the ADAM recognition motif in Cry3Aa toxin. Cry3Aa toxin mutants displayed decreased toxicity when comp…
Wkład ks. prof. Alojzego Kleina (1934–2002) w recepcję uzgodnień katolicko-reformowanych
2017
Artykuł przedstawia postać ks. prof. Alojzego Kleina (1934–2002), wieloletniego dyrektora Instytutu Ekumenicznego im. J.A. Möhlera w Paderborn, mającego wielkie zasługi w rozwoju ruchu ekumenicznego ze strony Kościoła katolickiego. W opracowaniu ukazano jedynie mały wycinek jego dorobku naukowego – wkład w recepcję uzgodnień katolicko reformowanych. Skoncentrowano się na dwóch fazach tegoż dialogu: fazie dialogu chrystologicznego i fazie dialogu eklezjologicznego. Końcowa część syntetycznie zbiera wyniki badań i formułuje wnioski.
Evolutionary relationships, biogeography and morphological characters of Glinus (Molluginaceae), with special emphasis on the genus composition in Su…
2021
Glinus is a small genus of Molluginaceae with 8–10 species mostly distributed in the tropics of the World. Its composition and evolutionary relationships were poorly studied. A new molecular phylogeny constructed here using nuclear (ITS) and chloroplast (rbcL, trnK-matK) markers confirmed the monophyly of the genus. Based on ITS analysis, the following well-supported lineages are present within Glinus: the G. bainesii lineage is recovered as sister to the remainder of the genus followed by G. oppositifolius. Three other clades are: G. hirtus with G. orygioides; G. radiatus and G. lotoides; the latter is represented by a sample from North America, and G. zambesiacus as sister to G. setifloru…
