Jitterbug/Filamin and Myosin-II form a complex in tendon cells required to maintain epithelial shape and polarity during musculoskeletal system development
(Elsevier Ireland Ltd, 2018)
© 2018 Elsevier B.V. During musculoskeletal system development, mechanical tension is generated between muscles and tendon-cells. This tension is required for muscle differentiation and is counterbalanced by tendon-cells ...
Automatic system for counting cells with elliptical shape
(Sociedade Brasileira de Redes Neurais - SBRNRio de Janeiro, 2011)
This paper presents a new method for automatic quantification of ellipse-like cells in images, an important and challenging problem that has been studied by the computer vision community. The proposed method can be described ...
Structural characterization of nuclear phenotypes during Scinax fuscovarius spermatogenesis (Anura, Hylidae)
(2003-01-01)
In anuran amphibian Scinax fuscovarius, the spermatogenesis occurs in structures called seminiferous loculi, in which germ epithelium is organized in spermatocysts. Each cyst contains cells in the same stage of ...
Amitosis, including nucleolar behaviour during fragmentation, in both axial and cortical cells of Chara contraria (Charales, Charophyta)
(Int Phycological Soc, 2007-03)
The results from the present study indicate that in Chara contraria the morphology of amitotic resting nuclei and amitosis depend essentially on the cell type as well to on some extent on the age and development of the ...
Ultrastructural study of the coagulating gland of Wistar rats submitted to experimental chronic alcohol ingestion
(1996-07-02)
Morphological changes of coagulating gland of Wistar rats submitted to the experimental chronic alcoholism were noted. Ultrastructurally, it was observed reduction of the granular endoplasmic reticulum cisternae and nuclei ...
The ultrastructure of the guinea pig rete testis
(2003-04-01)
The chambers of the rete testis (RT) of guinea pig are lined by a simple epithelium, whose cells are squamous, cubical and columnar in shape. The epithelial cells with distinct shapes were counted and the quantitative ...
PolyHEMA and polyHEMA-poly(MMA-co-AA) as substrates for culturing Vero cells
(Kluwer Academic PublDordrechtHolanda, 2000)
Degenerative process and cell death in salivary glands of Rhipicephalus sanguineus (Latreille, 1806) (Acari: Ixodidae) semi-engorged female exposed to the acaricide permethrin
(Wiley-Blackwell, 2012-08-01)
Ticks are ectoparasites of great medical and veterinary importance around the world and synthetic chemicals such as permethrin have been used for their control. This study provides a cytochemistry analysis of both degenerative ...
Morpho-functional study of human luteal cell subpopulations
(Oxford University Press, 1994)
It has been reported that the mammalian corpus luteum is composed mainly of two subpopulations of luteal cells (large and small) of different morphology and function. The aims of this study were first to characterize ...
