Fern-dominated Rock Plant Communities of Tajikistan (Middle Asia)

2015

The results of phytosociological research conducted on the fern vegetation of rock crevices and clefts of the Pamir-Alai Mountains in Tajikistan are presented. During field surveys done in 2010–2013, 78 phytosociological relevés were sampled. Plant species were recorded according to the Braun-Blanquet cover-abundance scale. A synopsis of the fern communities of the montane and high altitude zones in Tajikistan is proposed. In the examined vegetation plots, species of 9 ferns, 58 angiosperms and 13 mosses were recorded. The most frequent ferns were: Cystopteris fragilis, Cheilanthes persica, Asplenium ruta-muraria, Asplenium ceterach, Adiantum capillus-veneris and Cryptogramma stelleri. Six …

Isotope Fractionation of Selenium During Fungal Biomethylation by Alternaria alternata

2011

The natural abundance of stable Se isotopes may reflect sources and formation conditions of methylated Se. We aimed at (1) quantifying the degree of methylation of selenate [Se(VI)] and (hydro)selenite [Se(IV)] by the fungus Alternaria alternata at pH 4 and 7 and (2) determining the effects of these different Se sources and pH values on 82Se/76Se ratios (δ82/76Se) in methylselenides. Alternaria alternata was incubated with Se(VI) and Se(IV) in closed microcosms for 11-15 days and additionally with Se(IV) for 3-5 days at 30 °C. We determined Se concentrations and δ82/76Se values in source Se(VI) and Se(IV), media, fungi, and trapped methylselenides. In Se(VI) incubations, methylselenide vola…

Composition of the essential oil ofPallenis spinosa (L.) Cass. (Asteraceae)

2003

The essential oil of Pallenis spinosa (L.) Cass. was obtained by hydrodistillation. In total 38 components were identified by GC and GC–MS. Oxygenated sesquiterpenoids amounted to 60.2% of the oil. The main components were germacra-1(10),5-dien-3,4-diol (18.4%), α-cadinol (14.1%), 3-acetoxygermacra-1(10),5-dien-4-ol (13.0%), T-cadinol (8.2%) and δ-cadinene (5.8%). The oil does not show antimicrobial activity. Copyright © 2003 John Wiley & Sons, Ltd.

Professional burnout as a source of an early school education teacher’s career destabilization

2019

Nauczyciel, zawód czy misja? Dawniej nauczyciel często pełnił rolę kogoś w rodzaju mistrza lub wychowawcy, dyskutując z uczniem, obserwował go, uczył czytać, pisać, a także wprowadzał w arkana wiedzy filozoficznej i innych dziedzin nauk. Był zaliczany do grona elit intelektualnych. Obecnie również wizerunek nauczyciela koresponduje z wysokim poziomem prestiżu i zaufania społecznego, należy do grupy zawodów, które można opisać jako trudne, odpowiedzialne, stresujące, często prowadzące do destabilizacji zawodowej. W pracy podjęto próbę zobrazowania zjawiska wypalenia zawodowego jako asumptu destabilizacji kariery zawodowej nauczyciela edukacji wczesnoszkolnej, czynników wpływających na jego w…

Selenium: A Cure for Autoimmune Thyroiditis.

2021

Autoimmune thyroiditis (AT) is a disease whose incidence has increased dramatically over the past few decades. In iodine sufficient areas, this pathological condition affects up to 5% of the general population. The higher incidence of AT observed in areas of the world with low-selenium (Se) soils apperas to be the consequence of a reduced activity of the intracellular Sedependent glutathione peroxidase activity. Se is involved, through selenoproteins, in the regulation of intracellular antioxidant, redox and anti-inflammatory processes. As a component of selenoproteins, Se exerts various structural and enzymatic functions. A low Se/high fat diet can cause selenoprotein changes and promote t…

Vaccination Status and Attitudes towards Vaccines in a Cohort of Patients with Celiac Disease.

2022

(1) Background: The identification of vaccination status and attitudes towards vaccines among celiac disease (CD) patients is of great importance, but it has not yet been investigated. The aim of this study was to investigate coverage against vaccine-preventable diseases (VPDs), attitudes towards vaccinations, and its determinants among CD patients. (2) Methods: An anonymous web-based validated questionnaire was sent to a mailing list of CD adult patients. Patients were asked to self-report their previous vaccinations and attitudes towards vaccinations, which were defined as positive, negative, and partially positive/negative. The influencing factors towards vaccinations were investigated, …
