14. Effect of norbixin-based poly(hydroxybutyrate) membranes on the tendon repair process after tenotomy in rats
Abstract Purpose: To determine the efficacy of norbixin-based poly(hydroxybutyrate) (PHB) membranes for Achilles tendon repair. Methods: Thirty rats were submitted to total tenotomy surgery of the right Achilles tendon and divided into two groups (control and membrane; n = 15 each), which were further subdivided into three subgroups (days 7, 14, and 21; n

15. Co-transfection of hepatocyte growth factor and truncated TGF-β type II receptor inhibit scar formation
Wound scarring remains a major challenge for plastic surgeons. Transforming growth factor (TGF)-β plays a key role in the process of scar formation. Previous studies have demonstrated that truncated TGF-β type II receptor (t-TGF-βRII) is unable to continue signal transduction but is still capable of binding to TGF-β, thereby blocking the TGF-β signaling

16. Antioxidant-mediated protective role of Hericium erinaceus (Bull.: Fr.) Pers. against oxidative damage in fibroblasts from Friedreich’s ataxia patient
Abstract Friedreich’s ataxia (FRDA) is a progressive neuromuscular disorder caused by substantial decrease of mitochondrial protein frataxin responsible for biogenesis of iron-sulphur clusters and protection from oxidative damage. In this study, we investigated the antioxidant activities of a standardized aqueous extract from fruiting bodies of Hericium er

17. The protective effects of β-sitosterol and vermicularin from Thamnolia vermicularis (Sw.) Ach. against skin aging in vitro
Abstract: Aged skin, featured with dryness and wrinkles, has received mounting attention due to its adverse influences on beauty. β-Sitosterol and vermicularin are two common active ingredients of Thamnolia vermicularis (Sw.) Ach., a traditional Chinese medicine, of which the anti-aging effect has been discovered. Their protective performance against skin a

18. New tools for cell reprogramming and conversion: Possible applications to livestock
Abstract Somatic cell nuclear transfer and iPS are both forms of radical cell reprogramming able to transform a fully differentiated cell type into a totipotent or pluripotent cell. Both processes, however, are hampered by low efficiency and, in the case of iPS, the application to livestock species is uncertain. Epigenetic manipulation has recently emerged a

19. Superficial Acral Fibromyxoma: Literature Review
Resumo O fibromixoma acral superficial é um tumor raro de tecidos moles. Geralmente se manifesta por meio de uma massa indolor de crescimento lento que acomete principalmente adultos do sexo masculino na quinta década de vida. Ele normalmente afeta a região distal, com aparência polipoide. A aparência histológica é de uma massa dérmica sem cápsula,

21. Antibacterial and Cytotoxic Potential of a Brazilian Red Propolis
Abstract Objective: To evaluate in vitro the effect of a red propolis ethanolic extract (RPE) in the prevention of growth of a cariogenic biofilm and its cytotoxic potential. Material and Methods: Minimum inhibitory and bactericidal concentrations (MIC and MBC) of RPE against Streptococcus mutans and Lactobacillus casei were determined. The cytotoxic poten

23. Linear Peptide Analogues from Jatropha’s Orbitides Promote Migration of Human Neonatal Foreskin Fibroblasts in vitro and Collagen Deposition
Orbitides are a class of small naturally occurring cyclic peptides with structural and functional diversities. Their chemical properties make this class feasible to be obtained by solid phase peptide synthesis (SPPS). Therefore, this synthetic accessibility enables useful application and facilitates the identification of analogues, bioactivity studies, and t
