However, so far no study ... -
Evolutionary trade-of between innate and acquired immune defences in birds
(BMC Part of Springer Nature, 2023)Background The development, maintenance, and use of immune defences are costly. Therefore, animals face tradeofs in terms of resource allocation within their immune system and between their immune system and other ... -
Exogenous quercetin as a proliferation stimulator in tobacco BY-2 cells
(University of Warmia and Mazury in Olsztyn, 2017)Quercetin (Q) is a prominent flavonoid with a remarkable spectrum of biochemical activities. Its impact on human health as well as its endogenous role in the development of plants have been studied extensively. However, ... -

(EDP Sciences; Office National de l'Eau et des Milieux Aquatiques (ONEMA), 2020)This contribution presents first record of a blue colour morph of spiny-cheek crayfish, Faxonius limosus (Rafinesque, 1817). Two unusually coloured individuals were caught in Poland, in two different locations, separated ... -
First Record of Slime Molds in Biebrza National Park (NE Poland)
(Polish Botanical Society, 2021)This paper provides the first recorded data of slime molds in Biebrza National Park (NE Poland). In total, 16 species of myxomycetes belonging to nine genera were observed. -
First records of the Palaestes abruptus Sharp, 1899 and P. nicaraguae Sharp, 1899 (Coleoptera: Cucujidae) from South America, with a checklist of flat bark beetles from the continent
(Pensoft Publishers, 2021)Background: The flat bark beetles (Coleoptera: Cucujidae) is a small insect family with only about 70 species. Most of the species are distributed in Holarctic, Oriental and/or Australasian realms, while in South ... -
Functional consequences of piceatannol binding to glyceraldehyde-3-phosphate dehydrogenase
(Public Library of Science, 2018)Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is one of the key redox-sensitive proteins whose activity is largely affected by oxidative modifications at its highly reactive cysteine residue in the enzyme’s active site ... -
Gene and protein expression of glucose transporter 1 and glucose transporter 3 in human laryngeal cancer—the relationship with regulatory hypoxia-inducible factor-1α expression, tumor invasiveness, and patient prognosis
(Springer Netherlands, 2014-11-21)Increased glucose uptake mediated by glucose transporters and reliance on glycolysis are common features of malignant cells. Hypoxia-inducible factor-1α supports the adaptation of hypoxic cells by inducing genes related ... -
Gene and protein expression of O-GlcNAc-cycling enzymes in human laryngeal cancer
(Springer International Publishing, 2014)Aberrant protein O-GlcNAcylation may contribute to the development and malignant behavior of many cancers. This modification is controlled by O-linked β-N-acetylglucosamine transferase (OGT) and O-GlcNAcase (OGA). The aim ... -
Half a century of research on diatoms in athalassic habitats in central Poland
(De Gruyter, 2015-03)Part of the geology in the Łódź province was formed during the Upper Permian period when rich Zechstein salt was deposited. Groundwater drains the deposits and flows out in the village of Pełczyska, creating a unique ... -
