Forecasting SARS-CoV-2 epidemic dynamic in Poland with the pDyn agent-based model.

We employ pDyn (derived from "pandemics dynamics"), an agent-based epidemiological model, to forecast the fourth wave of the SARS-CoV-2 epidemic, primarily driven by the Delta variant, in Polish society. The model captures spatiotemporal dynamics of the epidemic spread, predicting disease-related states based on pathogen properties and behavioral factors. We assess pDyn's validity, encompassing pathogen variant succession, immunization level, and the proportion of vaccinated among confirmed cases.

Activity reconstruction of Rangifer tarandus feet in Fennoscandian -archaeology: Methodological considerations and application to archaeological material from two Sámi habitation sites.

Objective: This study explores the presence and prevalence of working Rangifer tarandus tarandus (domestic reindeer) through entheseal changes present in Rangifer tarandus phalanges at the Sámi habitation sites of Juikenttä and Nukkumajoki, located in Finland and dating from the 14th to the 18th centuries.

Materials: Modern samples (n = 23 phalanges, Rangifer tarandus fennicus; n = 60 phalanges, Rangifer tarandus tarandus non-working; n = 72 phalanges, Rangifer tarandus tarandus working) with known life histories. Archaeological samples (n = 22 phalanges, Juikenttä; n = 118 phalanges, Nukkumajoki).

Predictive performance of multi-model ensemble forecasts of COVID-19 across European nations.

Background: Short-term forecasts of infectious disease burden can contribute to situational awareness and aid capacity planning. Based on best practice in other fields and recent insights in infectious disease epidemiology, one can maximise the predictive performance of such forecasts if multiple models are combined into an ensemble. Here, we report on the performance of ensembles in predicting COVID-19 cases and deaths across Europe between 08 March 2021 and 07 March 2022.

Fast and reliable Sanger POLE sequencing protocol in FFPE tissues of endometrial cancer.

Background: The new classification of endometrial carcinoma (EC) requires molecular interpretation of somatic polymerase epsilon (POLE) exonuclease domain mutations. The identification of pathogenic mutations within the POLE gene defines the important subtype of ultramutated tumours ("POLE-ultramutated") with specified prognostic and predictive utility. POLE somatic mutations are present in 7-12% of ECs, usually high-grade tumours with aggressive appearance.

Detection of BRCA1/2 pathogenic variants in patients with breast and/or ovarian cancer and their families. Analysis of 3,458 cases from Lower Silesia (Poland) according to the diagnostic algorithm of the National Cancer Control Programme.

Breast and ovarian cancers are among the most common malignancies in the female population, with approximately 5-10% of cases being hereditary. and with other homologous recombination genes are the most tested genes in hereditary breast and ovarian cancer (HBOC) patients. As next-generation sequencing (NGS) has become a standard and popular technique, such as for HBOC, it has greatly simplified and accelerated molecular diagnosis of cancer.

Tendons and ligaments of the metapodial and hoof.

, the northern species including both reindeer and caribou, is a pillar of northern ecosystems and the lives of northern peoples. As the only domestic cervid, reindeer are important not only to the herders and hunters who presently interact with them, but also to zooarchaeologists and palaeontologists tracing their histories. Unfortunately, limited anatomical information on muscles is available beyond descriptions of the large muscle groups.

Induction of P-glycoprotein expression and activity by prolactin in female rat liver.

Aim: P-glycoprotein (P-gp) plays a critical role in the excretion of xenobiotics into bile. Previous studies have demonstrated that prolactin (PRL) regulates biotransformation and bile salt transport. Here we investigate whether the capability of the liver to transport xenobiotics into bile is altered in hyperprolactinemic states studying the modulation of hepatic P-gp by PRL.

Protective effect of genistein pre-treatment on paraquat hepatotoxicity in rats.

Paraquat (PQ), an herbicide widely used in agriculture, is considered a highly toxic compound. In hepatocytes, P-glycoprotein (P-gp/Abcb1) is a canalicular transporter involved in PQ extrusion from the cell. Previously, we demonstrated that genistein (GNT) induces P-gp in rat liver.

Regulation of hepatic P-gp expression and activity by genistein in rats.

P-glycoprotein (P-gp) is an ABC transporter exhibiting high pharmacotoxicological relevance by extruding a wide range of cytotoxic compounds out of the cells. Previously, we demonstrated that the phytoestrogen genistein (GNT) modulates P-gp expression in hepatocellular carcinoma in vitro. Although several beneficial effects (e.

Future Perspectives and Review on Organic Carbon Dots in Electronic Applications.

Over the span of the past decade, carbon dots (CDs) synthesized from renewable organic resources (organic CDs) have gathered a considerable amount of attention for their photoluminescent properties. This review will focus on organic CDs synthesized using clean chemistry and conventional synthetic chemistry from organic sources and their fluorescence mechanisms, such as quantum confinement effect and surface/edge defects, before outlining their performance in electronic applications, including organic photovoltaic devices, organic light-emitting devices, biosensors, supercapacitors, and batteries. The various organic resources and methods of organic CDs synthesis are briefly covered.

ABC Transporters: Regulation and Association with Multidrug Resistance in Hepatocellular Carcinoma and Colorectal Carcinoma.

For most cancers, the treatment of choice is still chemotherapy despite its severe adverse effects, systemic toxicity and limited efficacy due to the development of multidrug resistance (MDR). MDR leads to chemotherapy failure generally associated with a decrease in drug concentration inside cancer cells, frequently due to the overexpression of ABC transporters such as P-glycoprotein (P-gp/MDR1/ABCB1), multidrug resistance-associated proteins (MRPs/ABCCs), and breast cancer resistance protein (BCRP/ABCG2), which limits the efficacy of chemotherapeutic drugs. The aim of this review is to compile information about transcriptional and post-transcriptional regulation of ABC transporters and discuss their role in mediating MDR in cancer cells.
