Road-killed toads as a non-invasive source to study age structure of spring migrating population

Krzysztof Kolenda, Mikołaj Kaczmarski, Anna Najbar, Beata Rozenblut-Kościsty, more

European Journal of Wildlife Research > 2019 > 65 > 1 > 1-9

Development of road system causes worldwide barriers to wildlife movement and leads to mass road mortality which is a serious threat to the biodiversity, especially globally endangered amphibians. Animal carcasses, however, constitute an important non-invasive material for further research including species life history traits, but there is little known whether the road-killed animals are a representative...

The role of endoscopic ultrasound in diagnosing pancreatic neuroendocrine tumours

Przemysław Dyrla, Magdalena Chmielewska, Marta Mazur, Przemysław Witek

OncoReview > 2018 > 8 > 1 > 19-23

Pancreatic tumour imaging poses one of the greatest challenges in gastroenteropancreatic tumour diagnostics. Though much less common than adenocarcinomas, tumours deriving from pancreatic islets are the second most common group of pancreatic tumours. The manifestations and growth rate of neuroendocrine tumours (NETs) differ from adenocarcinomas; thus, these tumour types require different diagnostic...

The frequency of degenerating germ cells in the ovaries of water frogs (Pelophylax esculentus complex)

Paweł Szydłowski, Magdalena Chmielewska, Beata Rozenblut-Kościsty, Maria Ogielska

Zoomorphology > 2017 > 136 > 1 > 75-83

Pelophylax esculentus is the fertile hybrid of P. ridibundus and P. lessonae. During gametogenesis, one of the parental genomes is removed from the germ line cells, whereas the other one is clonally transmitted to the gametes. In hybrids, development of gonads is delayed in comparison with parental species. This may result from complex processes of genome elimination in female tadpoles at Gosner stages...

Xenopus LAP2β protein knockdown affects location of lamin B and nucleoporins and has effect on assembly of cell nucleus and cell viability

Magda Dubińska-Magiera, Magdalena Chmielewska, Katarzyna Kozioł, Magdalena Machowska, more

Protoplasma > 2016 > 253 > 3 > 943-956

Xenopus LAP2β protein is the single isoform expressed in XTC cells. The protein localizes on heterochromatin clusters both at the nuclear envelope and inside a cell nucleus. The majority of XLAP2β fraction neither colocalizes with TPX2 protein during interphase nor can be immunoprecipitated with XLAP2β antibody. Knockdown of the XLAP2β protein expression in XTC cells by synthetic siRNA and plasmid...

Expression of metallothioneins I and II in kidney of doxorubicin-treated rats

Magdalena Chmielewska, Krzysztof Symonowicz, Bartosz Pula, Tomasz Owczarek, more

Experimental and Toxicologic Pathology > 2015 > 67 > 4 > 297-303

Metallothioneins I/II (MT) are commonly expressed in mammalian tissues and are highly inducible in the response to stress conditions. Doxorubicin (DOX) intoxication promotes oxidative stress and subsequent apoptosis leading to kidney damage. The present study investigates a correlation between endogenous MT expression and DOX-induced apoptosis in renal tubular cells. Experiments were conducted on...

Nogo‐B expression, in arterial intima, is impeded in the early stages of atherosclerosis in humans

Katarzyna Drożdż, Irmina Grzegorek, Magdalena Chmielewska, Agnieszka Gomułkiewicz, more

APMIS > 122 > 9 > 742 - 749

Nogo‐B (Reticulon 4B) is considered to be a novel vascular marker, which may have a protective role in injury‐induced neointima formation and atherosclerosis. Nogo A/B is found to be crucial for monocyte/macrophage recruitment in acute inflammation and it is expressed in CD68 + macrophages. We hypothesize that macrophage infiltration in atherosclerosis is not dependent on Nogo‐B expression in arterial...

Bioprocess Development in Single‐Use Systems for Heterotrophic Marine Microalgae

Friederike Hillig, Steffi Annemüller, Magdalena Chmielewska, Maciej Pilarek, more

Chemie Ingenieur Technik > 85 > 1‐2 > 153 - 161

The utilization of single‐use systems is more and more common in upstream cultivation in biotechnological processes. The advantages of single‐use bioreactors for the cultivation of the heterotrophic microalgae Crypthecodinium cohnii serves as an example for the feasibility of polymer based orbital shaken systems for shear‐sensitive microorganisms with a high oxygen demand. Experiments in the shake...

In vitro effect of quercetin on human gastric carcinoma: Targeting cancer cells death and MDR

Sylwia Borska, Magdalena Chmielewska, Teresa Wysocka, Malgorzata Drag-Zalesinska, more

Food and Chemical Toxicology > 2012 > 50 > 9 > 3375-3383

The benefits of plant polyphenols as chemotherapeutic agents are of great interest due to their possible anti-cancerogenic activities. Results available up to now suggest that flavonoid quercetin induces lethal effect in many types of tumours and may sensitize resistant cells to drugs. The aim of our study was to examine the effect of quercetin on human gastric carcinoma cells and to determine mode...

Embryonic and adult isoforms of XLAP2 form microdomains associated with chromatin and the nuclear envelope

Magdalena Chmielewska, Magda Dubińska-Magiera, Mirosław Sopel, Dorota Rzepecka, more

Cell and Tissue Research > 2011 > 344 > 1 > 97-110

Laminin-associated polypeptide 2 (LAP2) proteins are alternatively spliced products of a single gene; they belong to the LEM domain family and, in mammals, locate to the nuclear envelope (NE) and nuclear lamina. Isoforms lacking the transmembrane domain also locate to the nucleoplasm. We used new specific antibodies against the N-terminal domain of Xenopus LAP2 to perform immunoprecipitation, identification...
