An innovative ear transplantation for vascularized composite allotransplantation research in porcine model.

Vascularized composite allotransplantation (VCA) represents a clinical challenge for transplant therapy, as it involves different tissues with unique immunogenicity. Even when receiving immunosuppressive therapy, they are more vulnerable to severe hypoxia, microvascular damage, and ultimately the rejection or chronic graft dysfunction after transplantation. This study aimed to develop a surgical protocol for VCA of the ear in a porcine biomodel in the absence of immunosuppression, maintaining the in vitro co-culture of the allograft and assessing their relationship with allograft survival.

Exploring developmental changes in femoral midneck cross-sectional properties.

This research delves deeper into previous works on femoral cross-sectional properties during ontogeny by focusing for the first time on the human femoral midneck. The ontogenetic pattern of cross-sectional properties at femoral midneck is established and compared with those at three different femoral locations: the proximal femur, the midshaft, and the distal femur. The study sample includes 99 femora (70 non-adults and 29 adults) belonging to archaeological specimens.

Complete Genome Sequences of Phages EarickHC, Figueroism, FinalFrontier, SBlackberry, Skylord, and Slay isolated using .

Phages EarickHC, Figueroism, FinalFrontier, SBlackberry, Skylord, and Slay were isolated from soil samples collected around Southern California using the host All six phages are lytic and have a siphoviral morphology. Genomes are 39,843 to 52,992 bp in length and contain 58 to 91 protein coding genes.

Myoblast-derived ADAMTS-like 2 promotes skeletal muscle regeneration after injury.

Skeletal muscle regeneration and functional recovery after minor injuries requires the activation of muscle-resident myogenic muscle stem cells (i.e. satellite cells) and their subsequent differentiation into myoblasts, myocytes, and ultimately myofibers.
