abstract aim and background: studying the role of background causes and biomarkers on early onset cardiovascular diseases' incidence as one important issue is need for prevention of these diseases. the purpose of this study was to identify the role of background factors and biomarkers for early onset cardiovascular diseases' incidence. methods and materials: in a descriptive study with cross-se...

The esterases of rabbit lung have been investigated from two viewpoints, the cytochemical and the biochemical. To accomplish this objective, we designed and synthesized a series of ester substrates which provide both a cytochemical indicator of the location of the enzyme and a means of following the enzymatic activity in tissue homogenates and subfractions. The substrates are p-nitrophenylthiol...

BACKGROUND The diabetes (db/db) mutation in C57BL/KsJ mice promotes a progressive cytolipidemia within the endometrial epithelial (EE) layer of the female reproductive tract which results in premature cellular and organ atrophy. The current studies focus on the ultrastructural and cytochemical changes which promote nuclear apoptosis and cytostructural disruption following the expression of endo...

While some workers have studied cytochemical localizations during oogenesis in molluscs (e.g. Arvy, 1949, 1950; Bretschneider & Raven, 1951; Collier, 1960; Cowden, 1961; Pasteels & de Harven, 1963), others have examined the ultrastructure of the developing oocyte using the electron microscope (e.g. Rebhun, 1956a, b, 1961; Worley & Hershenov, 1960; Pasteels & de Harven, 1963). This work has been...
