Sequence variants of p21 gene of the MRL/MpJ mouse: a possible association with the deficit of p21 protein and regenerative phenotype.
PublikacjaThe MRL/MpJ mouse is known for its enhanced regeneration abilities that manifested themselves by scarless ear-hole wound closure. The deficit of p21 found in the MRL is associated with the regenerative capacity as the p21 gene knockout in a mouse strain unrelated to the MRL mouse results in an ear-hole closure effect, similar to that observed in the MRL mouse. Cdkn1a gene encodes p21 protein, a cyclin-dependent kinase inhibitor,...

Study on Microstructural Characterization, Mechanical Properties and Residual Stress of GTAW Dissimilar Joints of P91 and P22 Steels
PublikacjaThis article deals with the dissimilar joining of two different grade Cr-Mo steel (2.25Cr-1Mo: P22 and modified 9Cr-1Mo: P91) for power plant application. The dissimilar butt-welded joint was produced for conventional V groove design by using the gas tungsten arc welding (GTAW) process with the application of an ERNiCrMo-3 Ni-based super alloy filler. A microstructure characterization was performed to measure the inhomogeneity...

Insight into heart regeneration
PublikacjaThe mammalian heart is thought to be incapable of regeneration because of the limited ability of cardiomyocytes. to proliferate. However, it has been recently shown that the neonatal murine heart is able to restore its normal function after coronary artery ligation or even partial resection. Unfortunately, this feature is lost in a few days after birth, although lower vertebrates as zebrafish or newt, retain this ability until adulthood. Therefore,...

The role of epigenetics in regeneration
PublikacjaComplex changes in chromatin structure and at the transcriptional level occur from the creation of a single parental gamete throughout fertilization, embryo development and the life of an adult organism. Epigenetic changes, such as methylation and hydroxymethylation of DNA or histone methylation and acetylation, are an important part of these processes. Epigenetic regulation has an essential influence on gene expression level. DNA...

Discovery of small-molecule regenerative drugs using a model of complex tissue injury in mice. Transcriptomic responses of neurodevelopmental genes during pharmacologically induced regeneration
PublikacjaDespite significant development in regenerative medicine, there is a deficit of effective therapies for wound healing and tissue regeneration. Research performed using animal wound models allows for a better understanding of this complex process, searching for compounds with pro-regenerative properties, and assessing their efficacy and safety. Unfortunately, the lack of adequate preclinical models proves to be an issue as no animal...

Places of worship, spiritual healing and urban regeneration
PublikacjaMany researchers demonstrated that it is possible to help people achieve mental and physical regeneration with proper architecture, urban and landscape planning. The term therapeutic landscapes could also be applied to places of worship, where people gather for spiritual healing and renewal. Public space that they offer is inclusively open to all. Addition- ally, they serve to reinvigorate the places where they are located. Shrines...
