Short‑term cell death in tissues of Pulsatilla vernalis seeds from natural and ex situ conserved populations
(Springer Nature, 2021)Pulsatilla vernalis is a IUCN listed species that occurs in mountain and lowland habitats. The seeds collected from different populations are remarkably diverse in their viability depending on locality or year of collection. ... -
Dissecting the RecA-(In)dependent Response to Mitomycin C in Mycobacterium tuberculosis Using Transcriptional Profiling and Proteomics Analyses
(MDPI, 2021)Mycobacteria exploit at least two independent global systems in response to DNA damage: the LexA/RecA-dependent SOS response and the PafBC-regulated pathway. Intracellular pathogens, such as Mycobacterium tuberculosis, are ... -
Air temperature and water level inferences from northeastern Lapland (69°N) since the Little Ice Age
(Polish Academy of Sciences; Committee on Polar Research, 2020)Independent Arctic records of temperature and precipitation from the same proxy archives are rare. Nevertheless, they are important for providing detailed information on long-term climate changes and temperature-precipitation ... -
Serotonin in the Pathogenesis of Lymphocytic Colitis
; Popławski, Tomasz; ; ; (MDPI, 2021)
Lymphocytic colitis (LC) is a chronic inflammatory disease associated with watery diarrhea, abdominal pain, and colonic intraepithelial lymphocytosis. Serotonin (5-hydroxytryptamine, 5-HT) is reported to increase in certain ... -
Long-term changes in fish community structure revealed by gillnet monitoring in a shallow, lowland reservoir
(Zachodniopomorski Uniwersytet Technologiczny w Szczecinie, 2017)Background. Fish communities can support or hinder water quality management. Sulejów Reservoir, which is situated on the Pilica River in Central Poland, serves as a strategic reserve of drinking water for the Łódź ... -
CBP/p300 Bromodomain Inhibitor–I–CBP112 Declines Transcription of the Key ABC Transporters and Sensitizes Cancer Cells to Chemotherapy Drugs
(MDPI, 2021)The high expression of some ATP-binding cassette (ABC) transporters is linked to multidrug resistance in cancer cells. We aimed to determine if I-CBP112, which is a CBP/p300 bromodomain inhibitor, altered the vulnerability ... -
Ruthenium Dendrimers against Human Lymphoblastic Leukemia 1301 Cells
; ; ; ; ; Sanz del Olmo, Natalia; ; ; ; ; (MDPI, 2020)
Ruthenium atoms located in the surfaces of carbosilane dendrimers markedly increase their anti-tumor properties. Carbosilane dendrimers have been widely studied as carriers of drugs and genes owing to such characteristic ... -
Composites Based on Hydroxyapatite and Whey Protein Isolate for Applications in Bone Regeneration
(MDPI, 2021)Hydroxyapatite (HAp) is a bioactive ceramic with great potential for the regeneration of the skeletal system. However, its mechanical properties, especially its brittleness, limit its application. Therefore, in order to ... -
Cellulose biosynthesis in plants – the concerted action of CESA and non-CESA proteins
(Institute of Experimental Botany of the Czech Academy of Sciences, 2020)Cellulose is the most abundant polysaccharide produced by plants. In the form of rigid microfibrils surrounding the cells, cellulose constitutes the load-bearing cell wall element that controls cell growth and shape. ... -
