Challenges of Implementing a Human Multi-Tissue Bank in a Public Hospital in the Interior of São Paulo: Under the Light of the Quality Management System.

Background: Human multi-tissue banks (HMTB) are important health institutions specialized in the capture, processing, and distribution of human tissues for transplants and research, aiming for safety and quality in the supply of their products, intended for reconstructive surgeries and injury repair, in addition to contributing to the advancement of research developed in regenerative medicine. This study aims to report and share the experience of implementing an HMTB, as well as creating an institution's own quality management system.

Methods: This is a descriptive study, an experience report type, which identifies historical aspects of an HMTB's actions in the 5 years of implementing and operating the service.

The role of platelet-rich plasma in the mild and severe stages of atherosclerotic disease in mice.

Platelet-rich plasma (PRP) has a high concentration of growth factors (GFs), which present a therapeutic wound healing effect. Despite having been correlated with an immunomodulatory function, the administration of PRP has not yet been investigated in atherosclerosis models. Evaluate the effect of lyophilized PRP on atherosclerosis in mice models through serum analysis.

The sodium-glucose cotransporter-2 (SGLT2) inhibitors synergize with nitric oxide and prostacyclin to reduce human platelet activation.

Gliflozins (canagliflozin, dapagliflozin and empagliflozin) are the newest anti-hyperglycemic class and have offered cardiovascular and renal benefits. Because platelets are involved in the atherothrombosis process, this study is aimed to evaluate the direct effect of gliflozins on platelet reactivity. Platelet-rich plasma (PRP) or washed platelets (WP) were obtained from healthy volunteers.

Hyperbaric oxygen affects endothelial progenitor cells proliferation in vitro.

Hyperbaric oxygen is a clinical treatment that contributes to wound healing by increasing fibroblasts proliferation, collagen synthesis, and production of growth factors, inducing angiogenesis and inhibiting antimicrobial activity. It also has been shown that hyperbaric oxygen treatment (HBO), through the activation of nitric oxide synthase promotes an increase in the nitric oxide levels that may improve endothelial progenitor cells (EPC) mobilization from bone marrow to the peripheral blood and stimulates the vessel healing process. However, cellular mechanisms involved in cell proliferation and activation of EPC after HBO treatment remain unknown.
