Screening of five essential oils for identification of potential inhibitors
Neves, A; Rosa, S; Gonçalves, J; Rufino, A; Judas, F; Salgueiro, L; Lopes, MC; Cavaleiro, C; Mendes, AFNuclear factor-kappaB is a key transcription factor activated by pro-inflammatory signals, like interleukin-1beta (IL-1), being required for the expression of many inflammatory and catabolic mediators, such as nitric oxide (NO), that play an important role in arthritic diseases. This work aimed at screening and identifying natural inhibitors of IL-induced NF-kappaB activation and NO production in human articula...
Expression and function of the insulin receptor in normal and osteoarthritic hu...
Rosa, S. C.; Rufino, A. T.; Judas, F.; Tenreiro, C.; Lopes, M. C.; Mendes, A. F.Objective Chondrocytes respond to insulin, but the presence and role of the specific high affinity insulin receptor (InsR) has never been demonstrated. This study determined whether human chondrocytes express the InsR and compared its abundance and function in normal and osteoarthritis (OA) human chondrocytes. Design Cartilage sections were immunostained for detection of the InsR. Non-proliferating chondrocyt...
Impact of congenital calcitonin deficiency due to dysgenetic hypothyroidism on ...
Daripa,M.; Paula,F.J.A.; Rufino,A.C.B.; Foss,M.C.The objective of the present study was to determine the effect of chronic calcitonin deficiency on bone mass development. The results of 11 patients with thyroid dysgenesis (TD) were compared to those of 17 normal individuals (C) and of 9 patients with other forms of hypothyroidism (OH): 4 with hypothyroidism due to inborn errors of thyroid hormone synthesis and 5 with Hashimoto's thyroiditis.
