Article Synopsis
  • Early detection and treatment of melanoma can dramatically improve survival rates, increasing from 25% to 99%.
  • The study analyzed gene expression data from various types of nevi (common, congenital, and dysplastic) to identify molecular pathways involved in the early development of melanoma.
  • Findings indicate that dysplastic nevi may act as a transitional phase toward melanoma, showing similarities in gene expression to early-stage melanoma tissue, while adjacent nevi revealed changes influenced by melanoma.

Purpose: The purpose of this study was to evaluate surgical feasibility and long-term integration of the CorNeat Keratoprosthesis (KPro), a novel synthetic cornea, in rabbits.

Methods: The CorNeat KPro is a synthetic corneal implant designed to treat corneal blindness by using a polymeric scaffold for biointegration, consequently assimilating synthetic optics within ocular tissues. Eight New Zealand White rabbits were implanted unilaterally with the CorNeat KPro and observed for 6 months.

This clinical study describes the intralesional application of the plasmid DNA encoding two therapeutic species-specific growth factors: vascular endothelial growth factor (VEGF164) and fibroblast growth factor 2 (FGF2) in seven horses to restore naturally occurring injuries of the superficial digital flexor tendon (SDFT) (tendinitis) and in three horses with suspensory ligament branch desmitis. Following application all horses were able to commence a more rapid exercise program in comparison to standardized exercise programs. Clinical observation and ultrasonic imaging was used to evaluate the regeneration rate of the tendon and ligament injury recovery and to confirm the safety of this gene therapy in horses, throughout a 12 month period.

This study investigated the influence of the estrus cycle in mediating cat odor-induced unconditioned and conditioned defensive behaviors in female Long-Evans hooded rats. Unconditioned defensive behaviors were assessed during predatory cue exposure; conditioned defensive behaviors were examined 24 h after threat exposure. Estrus phases were determined by microscopic examination of vaginal smears within 10 min of completing the behavioral tests.

In this clinical study, for the first time we used the direct gene therapy to restore severe injuries of the suspensory ligament branch and superficial digital flexor tendon in horses (). We injected the plasmid DNA encoding two therapeutic species-specific growth factors: vascular endothelial growth factor 164 and fibroblast growth factor 2 at the site of injury in the suspensory ligament branch and tendon. Treatment effects were evaluated with the use of clinical observation and ultrasound imaging during a period of a few months.
