Histochemical procedures for the demonstration of RNA have shown the presence of intensely basophilic bodies in the cytoplasm of spermatocytes of the crayfish, Cambarus virilis. The staining of thick sections, cut alternately with thin sections for electron microscopy, has permitted identification of the basophilic bodies with two types of lamellar systems. One of these, a set of straight annul...

Monoclonal antibody (MAb) 3C9, an antibody generated to the lamellar body of rat lung type II pneumocytes, specifically labels the luminal face of the lamellar body membrane. To follow the retrieval of lamellar body membrane from the cell surface in these cells, MAb 3C9 was instilled into rat lungs. In vivo, it was endocytosed by type II cells but not by other lung cells. In type II cells that ...

Chlorosomes are the main light harvesting complexes of green photosynthetic bacteria. Recently, a lamellar model was proposed for the arrangement of pigment aggregates in Chlorobium tepidum chlorosomes, which contain bacteriochlorophyll (BChl) c as the main pigment. Here we demonstrate that the lamellar organization is also found in chlorosomes from two brown-colored species (Chl. phaeovibrioid...

The adult instar of the oribatid mite, Galumna obvia (Berlese, 1914), is redescribed in detail, on the basis of specimens from Finland. The morphology of juvenile instars of G. obvia is described and illustrated for the first time, and compared to that of other species of the family Galumnidae. The position of the insertion of the lamellar seta in adults proved variable in studied European popu...

purpose: to report a case of candida glabrata endophthalmitis after deep anterior lamellar keratoplasty methods: interventional case report results: a young male patient presented with asymptomatic white to cream-colored interface deposits two months after deep anterior lamellar keratoplasty. after a while, severe anterior chamber reaction together with decreased visual acuity developed. becaus...

The regulation of cellular traction forces on the extracellular matrix is critical to cell adhesion, migration, proliferation, and differentiation. Diverse lamellar actin organizations ranging from contractile lamellar networks to stress fibers are observed in adherent cells. Although lamellar organization is thought to reflect the extent of cellular force generation, understanding of the physi...

lamellar keratoplasty (lk) has been a well established technique of corneal transplantation. recent improvements in surgical instruments have revolutionized the procedure introducing a new technique employing deeper corneal dissection. this review article describes the indications, techniques, outcomes and complications of deep anterior lk.

purpose: to determine the dissection level during deep lamellar keratoplasty (dalk) using the big-bubble technique by light microscopy (lm) and transmission electron microscopy (tem). methods: descemet’s membrane (dm) and stromal tissue of 4 keratoconic eyes were removed because of inadvertent intraoperative dm perforation during dalk which was converted to penetrating keratoplasty. these speci...

A method for culturing explants of lamellar hoof was developed to investigate the process of lamellar separation that occurs in laminitis. Explants, consisting of hoof wall, dermal and epidermal lamellae and the adjacent sub-lamellar connective tissue remained intact when cultured in tissue culture medium for 2 days. However, when cultured in the presence of the matrix metalloproteinase (MMP) a...
