Antioxidant, Pro-Survival and Pro-Regenerative Effects of Conditioned Medium from Wharton's Jelly Mesenchymal Stem Cells on Developing Zebrafish Embryos.

Conditioned media harvested from stem cell culturing have the potential to be innovative therapeutic tools against various diseases, due to their high content of growth, trophic and protective factors. The evaluation in vivo of the effects and biosafety of these products is essential, and zebrafish provides an ideal platform for high-throughput toxicological analysis, concurrently allowing the minimization of the use of mammalian models without losing reliability. In this study, we assessed the biological effects elicited by the exposure of zebrafish embryos to a conditioned medium derived from Wharton's jelly mesenchymal stem cells.

Outcomes of keratolimbal allograft from ABO compatible donors for severe bilateral limbal stem cell deficiency.

Purpose: To report outcomes of keratolimbal allograft (KLAL) compatible for both human leukocyte (HLA) and/or blood type using oral prednisone, mycophenolate, and tacrolimus, with basiliximab if panel reactive antibodies (PRA) are present. Intravenous immunoglobulin (IVIG) was used post-operatively if donor-specific anti-HLA antibodies (DSA) were present.

Methods: Retrospective interventional series of consecutive patients with KLAL for limbal stem cell deficiency (LSCD) from HLA and/or blood type compatible deceased donors with a minimum follow-up time of 12 months.

Wheelchair hockey improves quality of life in people with neuromuscular disease.

Background: Participation in sports is known to have positive effects on people's health and psychosocial well-being. Recently, physical activity implications for people with disabilities have been explored, showing promising results on quality of life and self-concept. However, few studies have specifically investigated the effects of participation in adaptive sports on quality of life in patients with neuromuscular disease.

Thyroid hormones in male workers exposed to urban stressors.

Background: The occupational exposure to urban pollution may induce adverse effects on the human health.

Methods: Plasma levels of thyrotropin stimulating hormone (TSH), free thyroxine (FT4) and free triiodothyronine (FT3) of 50 outdoor workers and 50 indoor workers were compared.

Results: In the outdoor workers the TSH levels were significantly higher than in the control subjects (p =0.
