SUMMARY: Neuropeptide calcitonin gene-related peptide (CGRP) is a neurotransmitter related to vasculogenesis during organ development. The vascular endothelial growth factor A (VEGF-A) is also required for vascular patterning during lung morphogenesis. CGRP is primarily found in organs and initially appe...
BACKGROUND: The distinct arterial and venous cell fates are dictated by a combination of various genetic factors which form diverse types of blood vessels such as arteries, veins, and capillaries. We report here that YULINK protein is involved in vasculogenesis, especially venous formation. METHODS: In t...
SUMMARY: Trophoblasts perform different functions depending on their location. This study aimed to obtain structural clues about the functions of villous and extravillous trophoblasts by using light and electron microscopy. Term placenta samples were obtained from 10 healthy pregnant women following cesa...
The vascular network expansion and functioning are important factors affecting normal intra-uterine fetal development. This study addressed the previously reported antiangiogenic potential of beta-2-glycoprotein I (β2GPI) in vivo in the chick embryo model of angiogenesis. The effects of two naturall...
Resumo Contexto Atualmente, recomenda-se como primeira opção cirúrgica de varizes a termoablação da veia safena; porém, esse procedimento não é realizado pelo Sistema Único de Saúde do Brasil. Como forma de incluir melhores resultados, técnicas cirúrgicas esforçam-se para mimetizar as novas...
The present study aimed to evaluate the effects of mesenchymal stem cells derived from canine adipose tissue in the healing process of full-thickness mesh skin grafts in rabbits. The stem cells were collected from young dogs; and, after characterization, remained in cryopreservation, in independent doses...
SUMMARY: The aim of this study was to perform an in situ endoscopic analysis of the vascularization of post-extraction sites immediately after a non-traumatic extraction in terms of the number of blood vessels per field (NBV), relative area of blood vessels (RABV) and relative area of unmineralized bone ...
RESUMEN: El tratamiento de dientes inmaduros necróticos es hoy un gran desafío clínico. La ausencia de cierre del ápice y el reducido grosor de las paredes de la dentina hacen que el tratamiento endodóntico del diente sea difícil e impredecible. Tradicionalmente, estos dientes han sido tratados con...
O objetivo deste trabalho foi avaliar macro e microscopicamente a atividade cicatrizante da Sphagneticola trilobata em feridas cutâneas induzidas em ratos, a partir da aplicação de creme contendo extrato hidroalcoólico bruto de folhas da planta. A análise fitoquímica apresentou terpenos e flavonoid...
La angiogénesis es el proceso por el cual se forman nuevos vasos sanguíneos a partir de otros ya existentes. Para que esto se lleve a cabo de forma correcta debe existir un balance entre los factores proangiogénicos y los factores antiangiogénicos dentro del microambiente tisular. Por otra parte, la ...
