Correlation among pAKT, pERK1/2 and DNA fragmentation index in human cumulus cells to determine oocyte competence
2018
The aim was to correlate specific biological aspects of cumulus cells isolated from individual cumulus-oocyte complexes (COCs) with the clinical outcome of the related embryos.
Elektroutlenianie przepracowanego oleju 15W-40
2017
W pracy przedstawiono badania nad możliwością wykorzystania odpadowego oleju silnikowego 15W-40 do bezpośredniego pozyskiwania energii elektrycznej. Pomiary obejmowały elektroutlenianie emulsji odpadowego (zużytego) oleju silnikowego 15W-40 na gładkiej elektrodzie platynowej w kwasowym elektrolicie (H2SO4). Do wytworzenia emulsji wykorzystano detergent Syntanol DS-10. Pomiary przeprowadzono w temperaturze 293-333K. Maksymalna uzyskana gęstość prądu wyniosła 19 mA/cm2 (dla temp. 333K). Badania wykazały możliwość bezpośredniego wytwarzania prądu elektrycznego z odpadowego oleju silnikowego 15W40, a więc możliwość zasilania nim ogniw paliwowych.
Bezpośrednie wytwarzanie energii elektrycznej z oleju napędowego
2016
Ze względu na stale wzrastające zapotrzebowanie na energię elektryczną poszukiwane są coraz to nowsze rozwiązania, pozwalające na sprostanie temu wyzwaniu. W ostatnich latach oprócz tradycyjnych metod wytwarzania energii coraz dynamiczniej rozwija się energetyka niekonwencjonalna. Przykładem takiego rozwiązania jest stosowanie ogniw paliwowych, głównie ze względu na ich wysoką sprawność. Ogniwa te przetwarzają energię chemiczną bezpośrednio na energię elektryczną, z pominięciem procesu spalania paliwa. Najczęściej zasilane są wodorem, jednak problemy z jego przechowywaniem wymuszają poszukiwanie innych paliw. Ponadto ogniwa paliwowe mogą stanowić dodatkowe/zapasowe źródło energii elektryczn…

Leczniczy charakter sakramentu pokuty
2016
In the twentieth century, in the understanding and practice of the penance sac rament and reconciliation in the Catholic Church, it was reminded clearly that apart from the judgement dimension, it also has an important healing aspect. Firstly, the paper discussed the healing dimension of the penitent’s acts (confession and satisfaction) and the healing role of forgiveness and reconciliation. Then, con fession and psychotherapy were briefl compared. Reflcting on the healing dimension of confession of sins and the conversation with a confessor, it can be noticed that while confessing something, the human identifis with what he or she confesses more consciously, and often he or she clearly rea…
Testing for Lynch Syndrome in Endometrial Carcinoma: From Universal to Age-Selective MLH1 Methylation Analysis
2022
Simple Summary International guidelines recommend universal screening of endometrial carcinoma patients for Lynch syndrome, a hereditary cancer predisposition syndrome. Screening is based on mismatch repair protein immunohistochemistry and reflex MLH1 methylation analysis to exclude the likely sporadic cases of MMR deficiency. As sporadic MLH1 protein loss is common in endometrial carcinoma, the ability to target methylation testing would save efforts and costs. We discovered that limiting methylation testing to patients under 65 years would have significantly reduced the testing effort while maintaining a low false negative rate for MLH1-LS detection (0% and 3% in our clinic and registry-b…
Intergenerational Effect of Early Life Exposure to Permethrin: Changes in Global DNA Methylation and in Nurr1 Gene Expression
2015
Environmental exposure to pesticides during the early stages of development represents an important risk factor for the onset of neurodegenerative diseases in adult age. Neonatal exposure to Permethrin (PERM), a member of the family of synthetic pyrethroids, can induce a Parkinson-like disease and cause some alterations in striatum of rats, involving both genetic and epigenetic pathways. Through gene expression analysis and global DNA methylation assessment in both PERM-treated parents and their untreated offspring, we investigated on the prospective intergenerational effect of this pesticide. Thirty-three percent of progeny presents the same Nurr1 alteration as rats exposed to permethrin i…
