Can apoptosis and necrosis coexist in ejaculated human spermatozoa during in vitro semen bacterial infection
Monika Fraczek,Magdalena Hryhorowicz,Dariusz Gaczarzewicz,Anna Szumala-Kakol,Tomasz Kolanowski,Lothar Beutin,Maciej Kurpisz +6 more
TL;DR: It is demonstrated for the first time that direct contact of conditionally pathogenic bacteria with ejaculated human sperm may play an even greater role in the promotion of apoptosis than in case of some pathogenic bacterial strains.
Protection from acetaminophen-induced liver damage by the synergistic action of low doses of the poly(ADP-ribose) polymerase-inhibitor nicotinamide and the antioxidant N-acetylcysteine or the amino acid l-methionine
TL;DR: The hepatoprotective effects of inhibitors of NAD-dependent adenoribosylation reactions and of antioxidants in analgesic-induced hepatic injury are investigated and a combination of both nicotinamide and N-acetylcysteine results in a complete protection from acetaminophen-induced release of GOT and GPT from injured liver cells.

Utility and Predictive Value of Human Standard Semen Parameters and Sperm DNA Dispersion for Fertility Potential.
Kamil Gill,Joanna Jakubik,Aleksandra Rosiak-Gill,Aleksandra Rosiak-Gill,Michal Kups,Mariusz Lukaszuk,Maciej Kurpisz,Monika Fraczek,Małgorzata Piasecka +8 more
TL;DR: There is a relationship between SDF and conventional sperm characteristics, and thus, SDF can be incorporated into male fertility assessment and shows that 18% SDF has a predictive value for distinguishing between men with normal and abnormal semen characteristics.

Global methylation status of sperm DNA in carriers of chromosome structural aberrations.
Marta Olszewska,Miroslawa Z. Barciszewska,Monika Fraczek,Nataliya Huleyuk,Vyacheslav B. Chernykh,Danuta Zastavna,Jan Barciszewski,Maciej Kurpisz +7 more
TL;DR: The low chromatin integrity might be associated with the high hypomethylation status of the sperm DNA observed in carriers of chromosome structural aberrations, and the potential relationship between sperm chromatin Integrity status and sperm DNA fragmentation was represented in a clearly opposite manner.

Analysis of mRNA for class I HLA on human gametogenic cells
Michal Janitz,Dorota Fiszer,Karolina Michalczak‐Janitz,Andrzej Lukaszyk,Nelson Fernandez,Witold Skorupski,Maciej Kurpisz +6 more
TL;DR: The minimal expression of classical HLA antigens may create a neutral cover for the male reproductive system, thereby preventing an immunological response during germ cell differentiation.
