âI don't understand, but it makes me laugh.â Domestication in contemporary Polish dubbing
Despite being (in)famous for its use of voice-over in fiction films, Poland also has a long-standing dubbing tradition. Contemporary Polish dubbing is largely domesticated: culture-bound items from the original are often replaced with elements of Polish culture, which is supposed to increase viewersâ enjoyment of the film. In this study, we examined whether Polish viewers can identify references to Polish culture in the contemporary Polish dubbing of foreign animated films and whether they enjoy them. With this goal in mind, we conducted an online survey and tested 201 participants. Given that many references relate to items from the near or distant past, we predicted that viewers may not fully understand them. The results show that, paradoxically, although viewers do not fully recognise references to Polish culture in contemporary Polish dubbing, they welcome such allusions, declaring that they make films more accessible. The most difficult category of cultural references to identify in our study turned out to be allusions to the canon of Polish literature, whereas the best scores were achieved in the case of references to social campaigns and films. Younger participants had more difficulties in recognising cultural allusions dating from before the 1990s compared to older participants. The vast majority of participants declared they enjoy domestication in contemporary Polish dubbing
Fatty acid extract from CLA-enriched egg yolks can mediate transcriptome reprogramming of MCF-7 cancer cells to prevent their growth and proliferation
BACKGROUND: Our previous study showed that fatty acids extract obtained from CLA-enriched egg yolks (EFA-CLA) suppressed the viability of MCF-7 cancer cell line more effectively than extract from non-enriched egg yolks (EFA). In this study, we analysed the effect of EFA-CLA and EFA on transcriptome profile of MCF-7 cells by applying the whole Human Genome Microarray technology. RESULTS: We found that EFA-CLA and EFA treated cells differentially regulated genes involved in cancer development and progression. EFA-CLA, compared to EFA, positively increased the mRNA expression of TSC2 and PTEN tumor suppressors as well as decreased the expression of NOTCH1, AGPS, GNA12, STAT3, UCP2, HIGD2A, HIF1A, PPKAR1A oncogenes. CONCLUSIONS: We show for the first time that EFA-CLA can regulate genes engaged in AKT/mTOR pathway and inhibiting cell cycle progression. The observed results are most likely achieved by the combined effect of both: incorporated CLA isomers and other fatty acids in eggs organically modified through hensâ diet. Our results suggest that CLA-enriched eggs could be easily available food products with a potential of a cancer chemopreventive agent.

The effect of "Nutramil^{TM} Complex," food for special medical purpose, on breast and prostate carcinoma cells
NutramilTM Complex is a multicomponent food product that meets the requirements of a food for special medical purpose. As a complete, high-energy diet it consists of properly balanced nutrients, vitamins and minerals. The aim of this study was to assess the effect of NutramilTM Complex on breast and prostate carcinoma cells. Our results showed that NutramilTM Complex reduced the viability and proliferation of breast and prostate cancer cells and that this process was associated with the induction of apoptosis via activation of caspase signalling. Data showed elevated levels of p53 tumour suppressor, up-regulation of p38 MAPK and SAPK / JNK proteins and downregulation of anti-apoptotic ERK1/2, AKT1 and HSP27. Treatment with NutramilTM Complex also affected the expression of the BCL2 family genes. Results also showed down-regulation of anti-apoptotic BCL-2 and up-regulation of pro-apoptotic members such as BAX, BAD, BID. In addition, we also observed regulation of many other genes, including IÎșÎČα, Chk1 and Chk2, associated with apoptotic events. Taken together, our results suggest activation of the mitochondrial apoptotic pathway as most likely mechanism of anti-carcinogenic activity of NutramilTM Complex
Can Adipokine FAM19A5 Be a Biomarker of Metabolic Disorders?
Agnieszka Wesołek-Leszczyńska,1,2 Katarzyna Pastusiak,1 Paweł Bogdański,1,* Monika Szulińska1,* 1Department of Treatment of Obesity, Metabolic Disorders and Clinical Dietetics, Poznan University of Medical Sciences, Poznań, Poland; 2Doctoral School, Poznan University Of Medical Sciences, Poznań, Poland*These authors contributed equally to this workCorrespondence: Agnieszka Wesołek-Leszczyńska, Department of Treatment of Obesity, Metabolic Disorders and Clinical Dietetics, Poznan University of Medical Sciences, 82/84 Szamarzewskiego Street, Poznań, 60-569, Poland, Tel +48Â 721Â 947 738, Email [email protected]; [email protected]: One of the most critical functions of adipose tissue is the production of adipokines, ie, numerous active substances that regulate metabolism. One is the newly discovered FAM19A5, whose older name is TAFA-5.Purpose: The study aimed to review the literature on the FAM19A5 protein.Methods: The review was conducted in December 2023 using the PubMed (Medline) search engine. Sixty-four papers were included in the review.Results: This protein exhibits the characteristics of an adipokine with positive features for maintaining homeostasis. The results showed that FAM19A5 was highly expressed in adipose tissue, with mild to moderate expression in the brain and ovary. FAM19A5 may also inhibit vascular smooth muscle cell proliferation and migration through the perivascular adipose tissue paracrine pathway. Serum levels of FAM19A5 were decreased in obese children compared with healthy controls. There are negative correlations between FAM19A5, body mass index, and fasting insulin. Serum FAM19A5 level is correlated with type 2 diabetes, waist circumference, waist-to-hip ratio, glutamic pyruvic transferase, fasting plasma glucose, HbA1c, and mean shoulder pulse wave velocity. FAM19A5 expression was reduced in mice with obesity. However, the data available needs to be clarified or contradictory.Conclusion: Considering todayâs knowledge about FAM19A5, we cannot consider this protein as a biomarker of the metabolic syndrome. According to current knowledge, FAM19A5 cannot be considered a marker of metabolic disorders because the results of studies conducted in this area are unclear.Keywords: fat tissue, metabolic syndrome, adipokines, adipocytes, obesit
Equilibrium Formation of Stable AllâSilicon Versions of 1,3âCyclobutanediyl
Main group analogues of cyclobutaneâ1,3âdiyls are fascinating due to their unique reactivity and electronic properties. So far only heteronuclear examples have been isolated. Here we report the isolation and characterization of allâsilicon 1,3âcyclobutanediyls as stable closedâshell singlet species from the reversible reactions of cyclotrisilene c âSi3Tip4 (Tip=2,4,6âtriisopropylphenyl) with the Nâheterocyclic silylenes c â[(CR2CH2)(Nt Bu)2]Si: (R=H or methyl) with saturated backbones. At elevated temperatures, tetrasilacyclobutenes are obtained from these equilibrium mixtures. The corresponding reaction with the unsaturated Nâheterocyclic silylene c â(CH)2(Nt Bu)2Si: proceeds directly to the corresponding tetrasilacyclobutene without detection of the assumed 1,3âcyclobutanediyl intermediate
Bactericidal activities of the cationic steroid CSA-13 and the cathelicidin peptide LL-37 against Helicobacter pylori in simulated gastric juice
BACKGROUND: The worldwide appearance of drug-resistant strains of H. pylori motivates a search for new agents with therapeutic potential against this family of bacteria that colonizes the stomach, and is associated with adenocarcinoma development. This study was designed to assess in vitro the anti-H. pylori potential of cathelicidin LL-37 peptide, which is naturally present in gastric juice, its optimized synthetic analog WLBU2, and the non-peptide antibacterial agent ceragenin CSA-13. RESULTS: In agreement with previous studies, increased expression of hCAP-18/LL-37 was observed in gastric mucosa obtained from H. pylori infected subjects. MBC (minimum bactericidal concentration) values determined in nutrient-containing media range from 100-800 ÎŒg/ml for LL-37, 17.8-142 ÎŒg/ml for WLBU2 and 0.275-8.9 ÎŒg/ml for ceragenin CSA-13. These data indicate substantial, but widely differing antibacterial activities against clinical isolates of H. pylori. After incubation in simulated gastric juice (low pH with presence of pepsin) CSA-13, but not LL-37 or WLBU2, retained antibacterial activity. Compared to LL-37 and WLBU2 peptides, CSA-13 activity was also more resistant to inhibition by isolated host gastric mucins. CONCLUSION: These data indicate that cholic acid-based antimicrobial agents such as CSA-13 resist proteolytic degradation and inhibition by mucin and have potential for treatment of H. pylori infections, including those caused by the clarithromycin and/or metronidazole-resistant strains
One Solar Cycle of Heliosphere Observations with the Interstellar Boundary Explorer: Energetic Neutral Hydrogen Atoms Observed with IBEX-Lo from 10 eV to 2 keV
The Interstellar Boundary Explorer (IBEX) is a NASA satellite in Earth orbit, dedicated to observing both
interstellar neutral atoms entering the heliosphere and energetic neutral atoms (ENAs) from the interstellar
boundaries from roughly 10 eV to 6 keV. This work presents the averaged maps, energy spectra, and temporal
variability of heliospheric ENA intensities measured with the IBEX-Lo instrument at 1 au at energies between
10 eV and 2 keV, covering one entire solar cycle from 2009 through 2019. These results expand the range in time
and energy for studying the globally distributed ENA flux and the IBEX Ribbon. The observed ENA intensities
exceed model predictions, in particular below 500 eV. Moreover, the ENA intensities between 50â200 eV energy
show an unexpected rise and fall around the year 2015 in most sky regions
Bildung Stabiler AllâSilicium Varianten von 1,3âCyclobutandiyl im Gleichgewicht
Hauptgruppenanaloga von 1,3âCyclobutandiylen faszinieren mit ihrer einzigartigen ReaktivitĂ€t und ihren elektronischen Eigenschaften. Bisher sind allerdings nur heteronukleare Vertreter isoliert worden. Wir berichten hier ĂŒber die Isolierung und Charakterisierung von AllâSiliciumâ1,3âCyclobutandiylen als stabile Singulettspezies mit geschlossenschaliger Konfiguration aus den reversiblen Reaktionen von Cyclotrisilen c âSi3Tip4 (Tip=2,4,6âTriisopropylphenyl) mit den Nâheterocyclischen Silylenen c â[(CR2CH2)(Nt Bu)2]Si: (R=H oder Methyl) mit gesĂ€ttigten GrundgerĂŒsten. Bei erhöhten Temperaturen werden aus diesen Gleichgewichtsmischungen Tetrasilacyclobutene erhalten. Die analoge Reaktion mit dem ungesĂ€ttigten Nâheterocyclischen Silylen c â(CH)2(Nt Bu)2Si: verlĂ€uft direkt zum entsprechenden Tetrasilacyclobuten ohne Nachweis des angenommenen 1,3âCyclobutandiylâZwischenprodukts
