Effects of Adipose-derived Stem Cells in the Treatment of Knee Osteoarthritis: A Case Report in Brazil's Unified Health System.

Osteoarthritis (OA) can incapacitate the individual to perform their activities of daily living due to pain. This is an important public health issue that worsens worldwide and in Brazil, since the population goes through an aging process, and has caused increased public spending on the monitoring and maintenance of treatments that can last for years and still not be resolutive. Thus, the search for innovative and effective therapies that can reduce costs becomes necessary.

The enzymatic disaggregation by trypsin does not alter cell quality and genomic stability of adipose-derived stem cells cultivated for human cell therapy.

There is no consensus between the protocols used for the isolation, maintenance and cultivation of Adipose-derived stem cells (ADSCs) for therapeutic purposes. Thus, was evaluated the maintenance method of ADSCs submitted to enzymatic disaggregation by trypsin. Was made (1st until 10th passage) immunophenotyping, cell differentiation assays, comet assay, differential cell death, apoptosis, cell viability and membrane integrity by flow cytometry.

Pyriproxyfen does not cause microcephaly or malformations in a preclinical mammalian model.

Pyriproxyfen is used in Brazil to combat epidemics of Dengue Fever, Chikungunya Fever, and Zika virus. This study assessed the effects of pyriproxyfen on reproductive performance, embryo-fetal development, head measurements, and DNA integrity in a preclinical model. Thirty pregnant mice were divided into three groups (n = 10): control (drinking water-0.
