damage to convoluted seminiferous tubules epithelium, reduction of spermatozoa formation and increase in prevalence of teratospermia, atrtic follicles congestion in stromal tissue, decrease in follicle and oocyte number, increased level of Cr(VI) in blood, increased duration of estrus cycle, disintegrated cell membranes of two layered follicular cells and altered
villiform mitochondria in thecal cells (Li et al.
Microscope observation of mycelium culture showed that the strain NS1-B started to be white and
villiform.
He also characterized and introduced a terminology for the shapes of the teeth (caniniform,
villiform, papilliform) and gill rakers (short and tuberous, short with a broad base, long and cylindrical).
Traditional serrated adenomas tend to be exophytic,
villiform, and are characterized by epithelium that has prominent pink cytoplasm with scattered goblet cells and remarkably uniform elongated hyperchromatic nuclei that stratify generally no more than half the thickness of the cells (Figure 4, A and B).
Diagnostic features: compressed and fusiform body, oblique or upper mouth, prominent lower jaw, very small teeth arranged in
villiform bands in the jaw, ventral gular plate between the two branches of the lower mandible, 32 to 36 gill rakers on the lower part of the first arch; 23 to 27 branchiostegals rays; simple and spineless dorsal fin with 13 to 16 rays, the last being a very long ray, anal fin with 21 to 25 soft rays, pectoral fins with 13 to 15 soft rays, pelvic fins with 10 or 11 soft rays; 37-42 large cycloid scales along the lateral line (Figure 1).
Lips fleshy and slightly fimbriated, the less developed rictal fold extending to the bases of maxillary barbel on both sides; oral teeth small and
villiform, premaxillary teeth in a single broad band, with a very shallow incision in the middle of the posterior edge, but no separation gap in the midline, dentary teeth in one narrow crescent band with a very narrow gap in the midline (Fig.
Male gonopods were elongated, sausage-shaped, and resided within a shallow trough just posterior to the anus and anterior to the anal fin origin, while the female cloaca possessed a circular, mound of
villiform tissue with a short, flattened tube for egg deposition.
Teeth in
villiform bands in the premaxilla and palatines and in a small patch on the vomer, premaxilla with an outer row of moderate conical teeth; outer teeth anteriorly with irregular inner series of smaller conical teeth and a wide inner band of much smaller teeth; small canine teeth in mandible and at premaxillary symphysis.
2) Only specialised columnar epithelium consisting of a
villiform growth pattern containing columnar, goblet, Paneth and endocrine cells (i.
The small intestine of tilapia is formed by a
villiform mucous layer consisting of a simple cylindrical epithelium which cells are known as enterocytes (SILVA et al.
Macrosculpture of metepisternum becoming
villiform ventrad.
Iris mammillations, which are tiny, numerous,
villiform, brown nodules occupying the iris stroma, are also common.
