Multispecific antigen-binding fragments (Fab) from rabbit antisera against rat very low density lipoproteins (VLDL) and Fab against rat low density lipoproteins that were monospecific for the B apoprotein were conjugated to horseradish peroxidase. Conjugates were incubated with 6-mum frozen sections from fresh and perfusion-fixed livers and with tissue chopper sections (40 mum thick) from perfu...

In previous work we have examined the nature of converting enzymes for proinsulin, proglucagon, and prosomatostatin-I (PSS-I) in secretory granules isolated from anglerfish islets. The purpose of the present study was to extend the examination of precursor conversion to islet microsomes and to compare prohormone processing, including that of PSS-I and prosomatostatin-II (PSS-II), in islet secre...

conclusions the current study indicated that the immunoreactivity of secretory iga might have no direct correlation with the colonization of indigenous flora and rejection of exogenous strains in adults. the relationship of microbes, host and dental caries should be in the light of coevolved microecosystem as a whole, but not caused by one factor alone. results the results showed that naturally...

The fine structure of the bat thyroid parafollicular cell has been examined at monthly intervals throughout the hibernating period. During November and December parafollicular cells appear either partly or totally degranulated and intact dense secretory granules are relatively sparse. The degranulated cells exhibit an inconspicuous Golgi complex and relatively few lysosome-type bodies. Few degr...

Mammary analogue secretory carcinoma (MASC) is an unusual and rare salivary gland malignancy that recapitulates the genetic microscopic features of breast (SCB) which equally entity. MASC SCB express S-100 protein, vimentin, mammaglobin, harbor a t (12; 15) (p13; q25) translocation leads to ETV6-NTRK3 fusion product. The morphology not specific can overlap with many tumors. S100 mammaglobin’s s...
