Intranuclear and Cytoplasmic Annulate Lamellae in Plant Cells

Annulate lamellae (AL) have hitherto been described for ammal cells (m particular, for germ cells), for embryomc systems, and for rapidly growing cells hke tumor and cancer ceils (for review, see references I0, 16) Such cisternae, which are either single or arranged m stacks of parallel lamellae, are characterized by the presence of pore complexes, i.e., pores of a relatively unitbrm srze distr...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Annulate Lamellae in Sarcoma I Cells

Annulate lamellae have been observed in eggs of marine invertebrates (1, 6, 12, 13, 18), rat spermatids (11, 17), crayfish spermatocytes (15), the amphibian pancreas (17), the adrenal cortex of the fetal rat (14), Sarcoma 37 cells (4), HeLa cells (5), Ehrlich and Yoshida ascites tumor cells (20), m ammary carcinoma cells of the rat (16), and cells of a chicken fibrosarcoma (3). Neither the orig...

Annulate lamellae in phloem cells of virus-infected Sonchus plants

The occurrence of annulate lamellae (AL) in differentiating phloem of Sonchus oleraceus (Compositae) singly infected with sowthistle yellow vein virus (SYVV) and doubly infected with a combination of SYVV and beet yellow stunt virus is documented by electron microscopy. Cell types in which AL were found were immature sieve elements and phloem parenchyma cells. AL were found only in cells that a...

Intranuclear Annulate Lamellae in Ascidian Embryos

Adult Boltenia villosa (phylum, Chordata; subphylum, Urochorda [Tunicata]; class, Ascidiacea) were collected intertidally. Gametes and embryos were handled according to standard procedures (Fernald, 1959; Costello et al., 1957). Living embryos in gastrula or neurula stages were pipetted into the fixative accompanied by a small amount of seawater. The fixative was either (a) 2.7% Os04 in approxi...
