Radiological incomplete thymus involution in systemic sclerosis.
OBJECTIVE Thymus plays a crucial role in immune system homeostasis, and thymic abnormalities have been previously reported in many autoimmune diseases, including SSc. The aim of this study is to evaluate the frequency of radiological thymus abnormalities in SSc patients and its relationship with various clinical and laboratory features. METHODS Sixty-three female SSc patients (diffuse/limited...
متن کاملThymus involution induced by 5-azacytidine.
Hypomethylation of DNA, which can be achieved by incorporation of 5-azacytidine, has been correlated with derepression of genes. In order to examine the in vivo effects of 5-azacytidine on organ development and differentiation, young rats were treated with the drug. There was an almost complete reduction of thymus and a marked reduction of spleen weight, while other organs, including testes wer...
متن کاملInvolution of the thymus: a possible diagnostic pitfall.
There were investigated 22 cases from which the thymic tissue was removed either during surgery for cardiovascular malformations (n = 14), or for myasthenia gravis (n = 8). Histological sections were stained with routine morphologic methods, and immunohistochemistry was performed for cytokeratin, CD20, CD3, and S100 protein. Aspects characteristic for thymus involution were found in 11 cases wi...
متن کاملInvolution Matrices of Real Quaternions
An involution or anti-involution is a self-inverse linear mapping. In this paper, we will present two real quaternion matrices, one corresponding to a real quaternion involution and one corresponding to a real quaternion anti-involution. Moreover, properties and geometrical meanings of these matrices will be given as reflections in R^3.
متن کاملThymus involution in alloxan diabetes: analysis of mast cells.
We previously reported that alloxan-induced diabetes results in reduction in the number and reactivity of mast cells at different body sites. In this study, the influence of diabetes on thymic mast cells was investigated. Thymuses from diabetic rats showed marked alterations including shrinkage, thymocyte depletion, and increase in the extracellular matrix network, as compared to those profiles...
