The addition lines derived from oat ( Avena sativa L.) × maize ( Zea mays L.) crosses constitute a unique tool for studying gene expression and the structure of chromatin, as well as a source of agronomically desirable traits in the context of new intergeneric hybrid cultivars. Therefore, for a better understanding of the introgression of maize chromatin into the oat genome, a comprehensive analysis of oat × maize lines was co...

Purpose The aim of this study was to analyze treatment outcomes and their predictors in children hospitalized due to varicella complicated by bacterial superinfections after pandemic of COVID-19. Methods This retrospective study analyzed data collected in a multicenter, nationwide, observational database dedicated for children aged 0–17 years hospitalized due to bacterial complications of varicella in 9 Polish tertiary healthc...

The endogenous level of cytokinins (CKs) and auxins (Auxs) was analyzed in isolated microspores and ovaries of two doubled haploid (DH) lines of triticale (× Triticosecale Wittm.) to better understand the mechanism of microspore embryogenesis (ME)—the most efficient and widely applied method of producing DHs. The responsiveness of the studied lines to ME significantly varied. ME was induced by pre-treating tillers with low tem...

Background Bone marrow stromal cells (BMSCs) form a perivascular cell population in the bone marrow. These cells do not present naïve myogenic potential. However, their myogenic identity could be induced experimentally in vitro or in vivo . In vivo , after transplantation into injured muscle, BMSCs rarely fused with myofibers. However, BMSC participation in myofiber reconstruction increased if they were modified by NICD or PAX...

The effectiveness of microspore embryogenesis (ME) is determined by a complex network of internal and environmental factors. In the present study on triticale and barley, strong positive correlation (r = 0.85) between the generation of hydrogen peroxide (H 2 O 2 ) and ME effectiveness confirmed the important role of reactive oxygen species in microspore reprogramming. However, for high effectiveness of ME induction, intensive...

The influence of ultrasonic pretreatment with specific energy input ranging from 25 to 550 kJ/kg volatile solids on the mixture of Sida hermaphrodita (L.) Rusby mixed with cattle manure disintegration and subsequent anaerobic digestion was assessed. The pretreatment process led to significant increase in the biomass solubility by 21.9% as chemical oxygen demand and enhanced biogas yield by 157% (567.1 L biogas/kg volatile soli...

Androgenic responsiveness in anther (AC) and isolated microspore cultures (MC) was analysed using 15 lines of Polish winter rye ( Secale cereale L.). The effect of low temperature (LT) alone or in combination with osmotic stress induced by mannitol treatment (MAN) and/or with reduced glutathione (GSH) on the effectiveness of the process was studied. Interestingly, each treatment had a different effect on microspore (mcs) vital...
