Leg adema

El lupus eritematoso generalizado (LEG) es una enfermedad autoinmune crónica caracterizada por la pérdida de la tolerancia a los antígenos propios y la síntesis de diferentes autoanticuerpos con la formación y depósito de complejos inmunes y el daño de múltiples órganos. Las células T reguladoras (Treg) desempeñan un papel esencial en el mantenimiento de la tolerancia periférica, controlan el estado de activación del sistema inmune y limitan las respuestas autoinmunes...

Objective: We investigated the proportion of Vβ T cell receptor (TCR) gene expression in peripheral CD3+ lymphocytes in familial and non-familial systemic lupus erythematosus (SLE) patients. Method: The Vβ TCR repertoire was studied in 14 families in which several members had SLE. The Vβ TCR usage in SLE patients (n = 27) was compared with that in healthy members of these multiplex families (n = 47), in 37 sporadic SLE patients who had no relatives with SLE, and in 15 healthy unrelated controls...

The thermal effect of high intensity focused ultrasound (HIFU) has been clinically exploited over a decade, while the mechanical HIFU is still largely confined to laboratory investigations. This is in part due to the lack of adequate imaging techniques to better understand the in-vivo pathological and immunological effects caused by the mechanical treatment. In this work, we explore the use of high frequency ultrasound (US) and photoacoustics (PA) as a potential tool to evaluate the effect of mechanical ablation in-vivo , e...

BACKGROUND: Thermal and mechanical high intensity focused ultrasound (HIFU) ablation techniques are in development for non-invasive treatment of cancer. However, knowledge of in vivo histopathologic and immunologic reactions after HIFU ablation is still limited. This study aims to create a setup for evaluation of different HIFU ablation methods in mouse tumors using high-field magnetic resonance (MR) guidance. An optimized MR-guided-HIFU setup could be used to increase knowledge of the different pathologic and immunologic reactions to different HIFU ablation methods...

Interference currents used in early treatment of patients with crural fractures accelarated recovery of the limb functions as a result of stimulation of involuntary muscular activity, reduced tissue adema and increased mobility of the ankle joint.
