      Ochyra had to devise the name Grimmia subanodon since the transfer of obtusifolium was blocked by the name Grimmia obtusifolia Gao & Cao from China. The species, as described by Ireland and Crum (), has muticous, concave, entire, obtuse leaves as the name applies but Greven's description and illustrations of Grimmia anodon do not describe. • Background and Aims The discovery of a new species, Haplophyllum bastetanum F.B. Navarro, V.N. Suárez-Santiago & Blanca sp. nov., in the south-east of Spain has prompted the comparative study of species of the Iberian Peninsula, and others related, through morphological, cytogenetic, molecular, distributional and ecological characterization.

Learn vocabulary, terms, and more with flashcards, games, and other study tools.   The study of cells is called Cytology which deals with the chemistry, function and structure of the examined cells. Both disciplines became an inherent part of the in-vitro diagnostics (IVD) and in-vivo diagnostics market and have evolved to a standard discipline in life science research since the early 19 th century. Many modern staining methods like in-situ hybridization (ISH) and.

    Zoology (/ z oʊ ˈ ɒ l ə dʒ i /) is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their term is derived from Ancient Greek ζῷον, zōion, i.e. "animal" and λόγος, logos, i.e. "knowledge, study". The genus GRIMMIA Hedw. is described and, as circumscribed in this monograph, includes 51 accepted species. Species descriptions are based on the study of specimens, including types. plates with drawings of morphological characters, series of anatomical characters found in the transverse sections of leaves and longitudinal sections.

Two New Species of Grimmia from Montana is an article from Bulletin of the Torrey Botanical Club, Volume View more articles from Bulletin of the Torrey.

Grimmia, with the exception of G. pulvinata, are nested within Grimmia in plastid phylogenies, but are sister to the remaining Grimmia groups and closer to Dryptodon based on nuclear DNA sequences. Introduction. With approximately 13 species, the Bryophyta compose the second most diverse phylum of land plants.

Mosses share with the Marchantiophyta and Anthocerotophyta a haplodiplobiontic life cycle that marks the shift from the haploid-dominated life cycle of the algal ancestors of embryophytes to the sporophyte-dominated life cycle of vascular by: cytology (M.B.P.

and B.A.C.) classified the cell groups as either LG morphology, which included NL cells, LGD, andIGD,orHGmorphology,whichincludedHGDand ACa. If there was not complete agreement regarding the exact classification of the cell groups but agreement that the cells were LG, the cell group was classified as LG atypia (LGA).Cited by: The role of cytology in endobronchial ultrasound‐guided transbronchial needle aspiration: A study of cases focusing on diagnostic yield, an analysis of misdiagnosed cases and diagnostic accordance rate of cytological subtyping.

The genus Grimmia Hedw. is described and, as circumscribed herein, includes 51 accepted species. Species descriptions are based on the study of specimens, including types.

Cytology is a simple, rapid, and inexpensive method used for pre-operative diagnosis of canine mammary tumors (CMTs) in veterinary practice. Studies related to human breast cancer showed the Robinson’s grading system—established for invasive ductal carcinoma, not otherwise specified (IDC, NOS) and used on cytological material—to not only closely correspond to the histopathological.

Gynecologic cytopathology is a subset of cytopathology. Gynecologic usually refers to Pap test specimens, i.e. uterine cervix, vaginal vault; other gynecologic specimens are considered non-gynecologic.

This article deals only with cervical cytopathology. An introduction to cytopathology is in the cytopathology article. Cervical cytology redirects to this article. Summarized are results of field studies of small, cushion-forming species of Grimmia in high altitude mountain areas of New York State, Vermont, New Hampshire, and Maine, and of associated research with herbarium specimens from these regions.

We here report eight species. Grimmia anodon is added to the flora of the Northeast, and new records and clarifications are presented for G. The progress in genetics and cytogenetics of the Gramineae during the past 14 years appears to be fairly comparable in quantity and quality with that made prior to this period.

Chromosome numbers are known for more than twice as many species of grasses as were known 14 years ago. Nevertheless, such reports are still unavailable for thousands of the grass species of the world.

Studies on Morphology and Cytochemistry in Blood Cells of Ayu Plecoglossus altivelis altivelis. The main cells in peripheral blood were divided into three groups; A, B and C.

Group A was subdivided into A1 and A2 (Fig. 1a and 1b), while Aa and Ab cells were obtained from a peripheral blood smear prepared using the wedge technique. Cytopathology, often called cytology, is the study of pathologic changes in cells.

Specimen types include exfoliated cervical cytology (Pap tests), urine, body cavity fluids (pleural, pericardial, and peritoneal), cerebrospinal fluid, and fine needle aspirations from any body site, among others (see detail articles section).These are often collected by minimally invasive means.
