    JEOL ultrathin sectioning
    Immunoelectron microscopic analysis showing GDNF-positive signals along the basal surface of Sertoli cells in hamsters. Electron micrographs showing transverse <t>ultrathin</t> sections of whole seminiferous tubules immunostained with anti-GDNF antibodies (DAB-osmium black). GDNF-positive signals are observed in the basal surface of Sertoli cells (S) adjacent to the spermatogonia (arrows) and the basal lamina (open arrowheads). Some signals are detected in the pinocytotic vesicles of peritubular myoid cells (double arrowhead in F). No signals are detected in the basal compartment of seminiferous tubules at stage XI (H, I). Panels B and C are higher magnified images of the basal surface of Sertoli cells in panel A. Asterisks, peritubular myoid cells; bl, basal lamina; G, spermatogenic cells; S, Sertoli cells. Scale bars represent 1 µm.

Inside them, some microgranules can be recognized due to their high electron density. Inset high magnification of a microspherule showing compacted microgranules ( dark ).

Semi-thin and ultrathin sections of liver were stained with methylene blue/azure II solution and uranyl acetate/lead citrate, respectively. Quantitative studies of histological damages were made individually in dengue (cases 1–4) and non-dengue patients (cont. 1–4), and statistical analysis were performed comparing the mean values of each group (dengue patients vs non-dengue patients). Damages were quantified by the percentage of affected area for (k) hemorrhage and (l) edema or (m) by steatosis degree using a scale ranging from 0 to 4. (n–o) Steatosis was also evaluated in each hepatic acini area (periportal, midzonal and central vein) by plotting different damage degrees (ten fields for each case).

    The nuclear membrane vesiculates after activation. <t>Ultrathin</t> cryosections of neutrophils stimulated with 20 nM PMA for 60 (a) and 180 (d) min and labeled with an antibody against the nuclear envelope–specific lamin B receptor. Bound antibody was detected with a gold-conjugated secondary antibody. In 60-min–stimulated neutrophils, the lamin B receptor was found on the inner nuclear membrane, as expected (a, arrows). 180 min after stimulation, the lamin B receptor was found in vesicles (d, arrows) in the cytoplasm. Nuclear material (d, arrowheads) is decondensed and not enclosed by a membrane. (b) 60 min after activation, neutrophils have flattened out and exhibit a lobulated nucleus and numerous granules. (c) Immunofluorescence staining for the nuclear membrane delineates the nuclear lobules (green) and is in continuity with the endoplasmic reticulum (red). (e and f) After 180 min of stimulation, neutrophil nuclei are inflated and fill nearly the entire cell. Some remaining granules are found in the periphery of the cell, while remnants of the nuclear membrane and the endoplasmic reticulum are restricted to a small central area surrounded by nuclear material (arrows). Bars: (a and d) 500 nm; (b, c, e, and d) 10 μm.

Bound antibody was detected with a gold-conjugated secondary antibody. In 60-min–stimulated neutrophils, the lamin B receptor was found on the inner nuclear membrane, as expected (a, arrows). 180 min after stimulation, the lamin B receptor was found in vesicles (d, arrows) in the cytoplasm. Nuclear material (d, arrowheads) is decondensed and not enclosed by a membrane. (b) 60 min after activation, neutrophils have flattened out and exhibit a lobulated nucleus and numerous granules. (c) Immunofluorescence staining for the nuclear membrane delineates the nuclear lobules (green) and is in continuity with the endoplasmic reticulum (red). (e and f) After 180 min of stimulation, neutrophil nuclei are inflated and fill nearly the entire cell. Some remaining granules are found in the periphery of the cell, while remnants of the nuclear membrane and the endoplasmic reticulum are restricted to a small central area surrounded by nuclear material (arrows). Bars: (a and d) 500 nm; (b, c, e, and d) 10 μm.

    Immunoelectron microscopic analysis showing GDNF-positive signals along the basal surface of Sertoli cells in hamsters. Electron micrographs showing transverse ultrathin sections of whole seminiferous tubules immunostained with anti-GDNF antibodies (DAB-osmium black). GDNF-positive signals are observed in the basal surface of Sertoli cells (S) adjacent to the spermatogonia (arrows) and the basal lamina (open arrowheads). Some signals are detected in the pinocytotic vesicles of peritubular myoid cells (double arrowhead in F). No signals are detected in the basal compartment of seminiferous tubules at stage XI (H, I). Panels B and C are higher magnified images of the basal surface of Sertoli cells in panel A. Asterisks, peritubular myoid cells; bl, basal lamina; G, spermatogenic cells; S, Sertoli cells. Scale bars represent 1 µm.

    The nuclear membrane vesiculates after activation. Ultrathin cryosections of neutrophils stimulated with 20 nM PMA for 60 (a) and 180 (d) min and labeled with an antibody against the nuclear envelope–specific lamin B receptor. Bound antibody was detected with a gold-conjugated secondary antibody. In 60-min–stimulated neutrophils, the lamin B receptor was found on the inner nuclear membrane, as expected (a, arrows). 180 min after stimulation, the lamin B receptor was found in vesicles (d, arrows) in the cytoplasm. Nuclear material (d, arrowheads) is decondensed and not enclosed by a membrane. (b) 60 min after activation, neutrophils have flattened out and exhibit a lobulated nucleus and numerous granules. (c) Immunofluorescence staining for the nuclear membrane delineates the nuclear lobules (green) and is in continuity with the endoplasmic reticulum (red). (e and f) After 180 min of stimulation, neutrophil nuclei are inflated and fill nearly the entire cell. Some remaining granules are found in the periphery of the cell, while remnants of the nuclear membrane and the endoplasmic reticulum are restricted to a small central area surrounded by nuclear material (arrows). Bars: (a and d) 500 nm; (b, c, e, and d) 10 μm.
