Chińska aktywność na Bałkanach w XXI wieku i jej implikacje
2022
Celem artykułu jest szkicowe przedstawienie, na podstawie analiz i materiałów prasowych, wielosektorowej obecności Chin na Bałkanach i jej wpływu na sytuację ekonomiczną regionu. Bałkany są ważne dla mocarstw ze względu na położenie geopolityczne i geostrategiczne na skrzyżowaniu szlaków międzykontynentalnych. Chiny znacząco wpływają na ekonomikę poszczególnych państw region, wykorzystując dyplomację publiczną celem ograniczenia wpływów ze strony innych ważnych graczy: Unii Europejskiej, Rosji i USA. Autorka przedstawia hipotezę, że Chiny, tak jak USA pod koniec XX wieku, zmierzają do stworzenia sfery wpływów na Półwyspie Bałkańskim, w kontekście swoich interesów globalnych. Bałkany są post…
Transcriptional changes through menstrual cycle reveal a global transcriptional derepression underlying the molecular mechanism involved in the windo…
2021
The human endometrium is a dynamic tissue that only is receptive to host the embryo during a brief time in the middle secretory phase, called the window of implantation (WOI). Despite its importance, regulation of the menstrual cycle remains incompletely understood. The aim of this study was to characterize the gene cooperation and regulation of menstrual cycle progression, to dissect the molecular complexity underlying acquisition of endometrial receptivity for a successful pregnancy, and to provide the scientific community with detailed gene co-expression information throughout the menstrual cycle on a user-friendly web-tool database. A retrospective gene co-expression analysis was perfor…

Jan Karol Chodkiewicz (1686–1712) – szkic biograficzny młodego magnata
2021
Artykuł stanowi próbę zaprezentowania postaci Jana Karola Chodkiewicza z linii supraskiej (1686–1712), syna starosty błudeńskiego i oboźnego wielkiego litewskiego Jerzego Karola Chodkiewicza oraz Marianny Tekli z Naruszewiczów, który do tej pory nie doczekał się żadnego szerszego opracowania naukowego. Podstawę źródłową szkicu biograficznego Chodkiewicza stanowią materiały przechowywane w Archiwum Narodowym w Krakowie, w zespole Archiwum Młynowskie Chodkiewiczów. Różnorodność znajdujących się w nim dokumentów pozwoliła na możliwie jak najdokładniejsze odtworzenie jego życiorysu. Z niego wyłania się postać Jana Karola, który osierocony przez ojca w dzieciństwie zdany był na opiekę swojej mat…
Identification of New Genetic Clusters in Glioblastoma Multiforme: EGFR Status and ADD3 Losses Influence Prognosis
2020
Glioblastoma multiforme (GB) is one of the most aggressive tumors. Despite continuous efforts to improve its clinical management, there is still no strategy to avoid a rapid and fatal outcome. EGFR amplification is the most characteristic alteration of these tumors. Although effective therapy against it has not yet been found in GB, it may be central to classifying patients. We investigated somatic-copy number alterations (SCNA) by multiplex ligation-dependent probe amplification in a series of 137 GB, together with the detection of EGFRvIII and FISH analysis for EGFR amplification. Publicly available data from 604 patients were used as a validation cohort. We found statistical associations…
New Insights into Potocki-Shaffer Syndrome: Report of Two Novel Cases and Literature Review
2020
Potocki-Shaffer syndrome (PSS) is a rare non-recurrent contiguous gene deletion syndrome involving chromosome 11p11.2. Current literature implies a minimal region with haploinsufficiency of three genes, ALX4 (parietal foramina), EXT2 (multiple exostoses), and PHF21A (craniofacial anomalies, and intellectual disability). The rest of the PSS phenotype is still not associated with a specific gene. We report a systematic review of the literature and included two novel cases. Because deletions are highly variable in size, we defined three groups of patients considering the PSS-genes involved. We found 23 full PSS cases (ALX4, EXT2, and PHF21A), 14 cases with EXT2-ALX4, and three with PHF21A only…
Immunohistochemical expression and distribution of orexin, orphanin and leptin in the major salivary glands of some mammals
2012
Abstract: The aim of the study was to assess the involvement of apoptotic factors, cytokeratins and metalloproteinase- 9 in the histogenesis of both Epithelialized Gingival Lesions (EGL) and Periapical Lesions (PAL). 55 consecutive patients, 30 with PAL and 25 with EGL, were selected for the study after clinical and radiological examinations. The PAL patients had severe periapical lesions and tooth decay with exposure of the pulp chamber. All PAL and EGL biopsies were surgically extracted, fixed in 10% buffered formalin, and processed for routine light microscopy. Ten biopsies of each category were processed for immunohistochemistry (IHC). Serial paraffin sections were stained by IHC with a…
Impact of nanoparticles on the environmental sustainability of polymer nanocomposites based on bioplastics or recycled plastics – A review of life-cy…
2022
Adding nanoparticles to a host polymer can lead to performance improvements that can be twice as beneficial to the environment: first, sustainable nanocomposites based on bioplastics or recycled plastics could replace ubiquitous petroleum-based polymers; second, substantial plastic saving could be achieved by profiting from the superior specific properties of the nanocomposites. Nevertheless, the inherent environmental burden of nanoparticles can compromise the expected benefits. Here we address the controversial issue of the environmental sustainability of “green” polymer nanocomposites based on bioplastics and recycled plastics. A critical review of life-cycle assessment studies regarding…
Open-shell doublet character in a hexaazatrinaphthylene trianion complex
2015
Three-electron reduction of hexaazatrinaphthylene (HAN) with a magnesium(I) reagent leads to [(HAN){Mg(nacnac)}3] (1), containing a [HAN]3– ligand with a spin of S = ½. Ab initio calculations reveal that the [HAN]3– ligand in 1 has a groundstate wave function with multiconfigurational properties, and can be described as a triradicaloid species with a small amount of open-shell doublet character. peerReviewed
Imbalance between genomic gain and loss identifies high-risk neuroblastoma patients with worse outcomes
2021
Survival in high-risk neuroblastoma (HR-NB) patients remains poor despite multimodal treatment. We aimed to identify HR-NB patients with worse outcomes by analyzing the genomic instability derived from segmental chromosomal aberrations. We calculated 3 genomic instability indexes for primary tumor SNP array profiles from 127 HR-NB patients: (1) Copy number aberration burden (%gainslength+%losseslength), (2) copy number load (CNL) (%gainslength-%losseslength) and (3) net genomic load (NGL) (%gainsamount-%lossesamount). Tumors were classified according to positive or negative CNL and NGL genomic subtypes. The impact of the genomic instability indexes on overall survival (OS) was assessed with…
