Andrzej Bobkowski - życie, twórczość, recepcja

Andrzej Bobkowski był autorem kilku esejów i opowiadań drukowanych na łamach prasy krajowej i emigracyjnej, w tym fragmentów dziennika z czasów okupacji przeżytej we Francji i notatnika z podróży do Gwatemali, gdy w 1957 roku Instytut Literacki w Paryżu wydał jego „Szkice piórkiem” – dziennik z czasu wojny. Tym dziełem zapisał się na trwałe w historii polskiej literatury. Potem były jeszcze tylko pojedyncze teksty opublikowane w czasopismach emigracyjnych i zebrane w pośmiertnych zbiorach, m.in. „Coco de Oro” oraz listy, które ukazywały się stopniowo periodykach, a z czasem w wydaniach książkowych (m.in. z Jerzym Giedroyciem, Jarosławem Iwaszkiewiczem, Tymonem Terleckim). Jednak mimo skromnej spuścizny literackiej Bobkowski uważany jest za jednego z najciekawszych autorów polskiej emigracji powojennej. Choć od kilkunastu lat nie ustaje zainteresowanie jego twórczością (ukazują się kolejne tomy listów, opracowania i rozprawy) dotąd nie powstała biografia pisarza. Rozprawa doktorska „Andrzej Bobkowski – życie, twórczość, recepcja”, jest próbą uzupełnienia tej luki. Autorka analizując teksty literackie, listy, dokumenty, sięgając po różnorodne informacje archiwalne i relacje, stara się pokazać środowisko, w jakim pisarz się wychowywał i dorastał, a także wydarzenia historyczne, które miały bezpośredni wpływ na jego pisarstwo. Praca jest efektem wieloletnich poszukiwań w Polsce, Francji, Stanach Zjednoczonych, w Gwatemali, przedstawia różnorodne aspekty życia i twórczości Andrzeja Bobkowskiego

Bioactive Compounds in Different Buckwheat Species

The accumulation of valuable nutrients in cereal grains depends on a number of factors, including species, cultivars, and environment conditions. The aim of this study was to compare protein, some polyphenols and rutin content, as well as mineral composition in Fagopyrum tataricum and Fagopyrum esculentum genotypes growing in Polish conditions. A field experiment was conducted on pseudopodsolic soil in 2017–2018 at the Experimental Station in Osiny (51°35′, 21°55′), following randomized complete block method with three replications. Two cultivars of Fagophyrum esculentum (Kora and Panda), two cultivars of Fagopyrum tataricum (LIT1 and 63181) and two forms of Fagopyrum esculentum (Red Corolla and Green Corolla) were used in this experiment. We found differences in the tested compounds (protein, phenolic acids, rutin, and mineral composition) between cultivars and genotypes. Total phenolic acid and rutin contents were higher in the Fagopyrum tataricum compared to Fagopyrum esculentum. Ferulic and coumaric acids were prominent in the Kora and Panda cultivars, however vanillic and syringic acids accumulated more in Green Corolla and Red Corolla. The common buckwheat seeds contained more Cu, Mn, and Mg and less Ca than tartary buckwheat. Moreover Fagopytum esculentum genotype contains more protein compared to Fagopyrum tataricum

Updated Review of the Toxicity of Selected <i>Fusarium</i> Toxins and Their Modified Forms

Mycotoxins are one of the most dangerous food and feed contaminants, hence they have significant influence on human and animal health. This study reviews the information reported over the last few years on the toxic effects of the most relevant and studied Fusarium toxins and their modified forms. Deoxynivalenol (DON) and its metabolites can induce intracellular oxidative stress, resulting in DNA damage. Recent studies have also revealed the capability of DON and its metabolites to disturb the cell cycle and alter amino acid expression. Several studies have attempted to explore the mechanism of action of T-2 and HT-2 toxins in anorexia induction. Among other findings, two neurotransmitters associated with this process have been identified, namely substance P and serotonin (5-hydroxytryptamine). For zearalenone (ZEN) and its metabolites, the literature points out that, in addition to their generally acknowledged estrogenic and oxidative potentials, they can also modify DNA by altering methylation patterns and histone acetylation. The ability of the compounds to induce alterations in the expression of major metabolic genes suggests that these compounds can contribute to the development of numerous metabolic diseases, including type 2 diabetes
