25. TNF-alpha increases angiogenic potential in a co-culture system of dental pulp cells and endothelial cells
Abstract We recently demonstrated that a co-culture system of human umbilical vein endothelial cells (HUVECs) and human dental pulp stem cells (hDPSCs) could enhance angiogenesis ability in vitro. However, whether tumor necrosis factor α (TNF-α) could promote blood vessel formation during pulp regeneration remained unknown. The aim of this study was to inv

26. Protocols for preparation of platelet rich plasma (PRP) in Quarter Horses
RESUMO: Este estudo comparou dois protocolos de preparo de plasma rico em plaquetas (PRP) e avaliou a associação entre dois métodos de contagem plaquetária - um manual e o outro automático através de um estudo prospectivo. Sangue venoso de oito equinos da raça Quarto de Milha foi coletado e em seguida foi centrifugado duas vezes utilizando-se dois pro

27. The role of KDR in intrauterine adhesions may involve the TGF-β1/Smads signaling pathway
The aim of this study was to investigate the role of kinase-insert domain-containing receptor (KDR) in intrauterine adhesions (IUA) and its mechanism. The Case group consisted of 92 patients diagnosed with IUA, and the Control group included 86 patients with uterine septum who had normal endometrium verified with an uteroscope. In addition, 50 rats were rand

28. Clinical attachment loss and molecular profile of inflamed sites before treatment
Abstract Objective: To monitor early periodontal disease progression and to investigate clinical and molecular profile of inflamed sites by means of crevicular fluid and gingival biopsy analysis. Methodology: Eighty-one samples of twenty-seven periodontitis subjects and periodontally healthy individuals were collected for the study. Measurements of clinica

29. Endothelial progenitor cells and vascular endothelial growth factor in patients with Takayasu's arteritis
Abstract Background: Endothelial progenitor cells (EPCs) are responsible for endothelial damage repair. Takayasu's arteritis (TA) is a chronic inflammatory disease that affects large vessels. The aim of the study was to evaluate the number of EPCs and the levels of vascular endothelial growth factor (VEGF) and the relationship of these variables in patients

30. Relevance of serum angiogenic cytokines in adult patients with dermatomyositis
Abstract Background: Until now, there are few studies evaluating serum levels of angiogenic cytokines in dermatomyositis (DM). Therefore, the aims of the present study were: (a) to analyze systematically and simultaneously serum levels of angiogenin (ANG), angiopoietin (ANGPT)-1, vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF)- 1 a

31. Treatment of bisphosphonate-related osteonecrosis using platelet-rich plasma: microtomographic, microscopic, and immunohistochemical analyses
Abstract The present study aimed to investigate the use of platelet-rich plasma (PRP) on tooth extraction sites in rats treated with bisphosphonates. Thirty Albinus Wistar male rats were administered 0.035 mg/kg zoledronic acid intravenously for 8 weeks, divided into four administrations with a 2-week interval between each application, after which their uppe

32. Is the effect of melatonin on vascular endothelial growth factor receptor-2 associated with angiogenesis in the rat ovary?
OBJECTIVES Vascular endothelial growth factor (VEGF) and its receptors play important roles in angiogenesis. Melatonin plays an important role in gonadal development; thus, its effect on the reproductive system is evident. We investigated the influence of melatonin on the expression of VEGF, vascular endothelial growth factor receptor-1 (VEGFR1) and vascul
