Non-tumor necrosis factor-based biologic therapies for rheumatoid arthritis: pr...

Therapeutic options for patients suffering from the more severe forms of spondyloarthritis have been rather limited in the last decades. There is now accumulating evidence that antitumor necrosis factor therapy is highly effective in spondyloarthritis, especially in ankylosing spondylitis and psoriatic arthritis. Based on the data recently published on more than 500 patients with ankylosing spondylitis and psor...

Green propolis phenolic compounds act as vaccine adjuvants, improving humoral a...

Adjuvants play an important role in vaccine formulations by increasing their immunogenicity. In this study, the phenolic compound-rich J fraction (JFR) of a Brazilian green propolis methanolic extract stimulated cellular and humoral immune responses when co-administered with an inactivated vaccine against swine herpesvirus type 1 (SuHV-1). When compared to control vaccines that used aluminium hydroxide as an ad...

Longitudinal evaluation of hepatic osteodystrophy in children and adolescents w...

Bone mass loss is a major complication of chronic cholestatic liver disease (CCD). However, the long-term impact of CCD on bone mass acquisition is unknown. We longitudinally assessed bone mineral density (BMD) and factors involved in bone remodeling in 9 children and adolescents with CCD Child-Pugh A (5 boys/4 girls) and in 13 controls (6 boys/7 girls). The groups were evaluated twice, at baseline (T0) and aft...

Perfil nutricional e cardiovascular de ratos normotensos e hipertensos sob diet...

FUNDAMENTO: Embora dietas hiperlipídicas (DH) promovam distúrbios nutricionais e cardíacos, poucos estudos avaliaram sua influência em ratos normotensos Wistar-Kyoto (WKY) e espontaneamente hipertensos (SHR). OBJETIVO: Avaliar e comparar o perfil nutricional e cardiovascular de WKY e SHR tratados com DH. MÉTODOS: 20 WKY e 20 SHR foram distribuídos em quatro grupos: WKY-controle (WKY-C), WKY-DH, SHR-controle (SH...

Gluteus maximus and semitendinosus activation during active prone hip extension...

BACKGROUND: Gluteus maximus strengthening exercises are employed in clinical practice as options for the treatment of low back and sacroiliac disorders. However, no studies were found that investigated which were the best exercises to activate this muscle and justify its employment in physical therapy practice. OBJECTIVE: To quantify the electromyographic (EMG) activity of the gluteus maximus and semitendinosus...

X-DLVO Interactions between nanocolloidal magnetic particles: the quantitative ...

The phase behavior of acidic samples of EDL-MF based on cobalt ferrite nanoparticles with controlled mean sizes was investigated at constant temperature and in absence of magnetic field. By monitoring the nanoparticle charge by pH adjustments, we constructed an experimental pH-dependent phase diagram for all samples that revealed sol, gel thixotropic or coagulated phases in different pH regions. Then, by using ...

Gravitational and magnetic separation in self-assembled clay-ferrofluid nanocom...

We report on experimental observations of self-assemblies in colloidal dispersions of clay nanoplatelets and magnetic nanoparticles. Visual observations have been combined with small angle X-ray scattering (SAXS) in the study of several composites at a fixed clay concentration in the dilute regime, and varying ferrofluid concentrations. Our visual observations which encompass macroscopic separation in gravitati...
