BACKGROUND AND PURPOSE Although the thymus is centered in the mediastinum, often a cervical component can be seen in children and young adults. The frequency of radiologically evident residual cervical thymus in older adults is not known. The purpose of our study was to determine the proportion of adults who have residual cervical thymus visible on contrast-enhanced neck CT. MATERIALS AND MET...

Antibodies to chromatographically purified rat thymus Fl histone subfractions were induced in rabbits by immunization with histone-RNA complexes. The immunological relatedness between each of the rat thymus Fl subfractions and subfractions derived chromatographically from calf thymus and rat liver Fl was determined by quantitative microcomplement fixation. The various rat thymus peaks elicited ...

Estimation of the success ecosystem restoration through different methods is essential planning projects, especially nowadays when world community has declared target for an effective 25% degraded ecosystems in next years. In present study, we intro­duce results application two land preparation – soil ripping and terracing - on twenty years after actions. The study concerns reforested areas wit...

The taxonomy of the genus Stylophoronychus (Acari: Tetranychidae) is reviewed. The synonymy of Stylophoronychus Prasad, 1975 and Sinotetranychus Ma & Yuan, 1980 is accepted and the former has priority. As a result, the following new combinations are noted: Stylophoronychus guangzhouensis (Ma & Yuan) and Stylophoronychus insularis (Flechtmann). S. baghensis (Prasad) is newly recorded from the mo...

Thymus is a bilobed organ usually situated in the superior mediastinum. Thymus is normally active until puberty and as age advances it undergoes considerable fibrofatty degeneration and is replaced by fatty tissue. We found a persistent thymus in an adult male cadaver aged 70 years approximately. It apparently looked healthy. Hence the objective of this study was to know the morpho-histology of...
