Structure of muscle filaments from immunohistochemical and ultrastructural studies.

Ultrastructural Studies on the Lymphatic Anchoring Filaments

The fine structure of the lymphatic capillary and the surrounding tissue areas was investigated. Instead of a continuous basal lamina (basement membrane) surrounding the capillary wall, these observations revealed the occurrence of numerous fine filaments that insert on the outer leaflet of the trilaminar unit membrane of the lymphatic endothelium. These filaments appear as individual units, or...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Glycohistochemical, Immunohistochemical and Ultrastructural Studies of the Bovine Epididymis

Follicular dendritic cell sarcoma: ultrastructural and immunohistochemical studies.

A rare case of follicular dendritic cell (FDC) sarcoma is reported. A 71-year-old woman was admitted for evaluation of constipation. Computerized tomography showed cervical, supraclavicular, retroperitoneal, and paraaortic lymphadenopathies. Histological findings from a cervical lymph node revealed Hodgkin's disease at first. But tumors that arose both in the cervical and the left interscapular...

Biochemical, ultrastructural, and reversibility studies on huntingtin filaments isolated from mouse and human brain.

Huntington's disease (HD) and eight additional inherited neurological disorders are caused by CAG triplet-repeat expansions leading to expanded polyglutamine-sequences in their respective proteins. These triplet-CAG repeat disorders have in common the formation of aberrant intraneuronal proteinaceous inclusions containing the expanded polyglutamine sequences. These aggregates have been postulat...
