Geometric morphometric analyses were conducted on cultured populations of five Micrasterias species (M. crux-melitensis, M. papillifera, M. rotata, M. thomasiana, M. truncata). The patterns in the morphological variation measured using the morphospaces spanned by a PCA of morphometric data for individual populations were compared. In addition, the 18S rDNA sequences of these species are reporte...

We assessed the effects of various dietary conditions on the growth, phenotypic traits, and morphometric dimensions of rock bream, Oplegnathus fasciatus and on the morphometric dimensions of sectioned olive flounder, Paralichthys olivaceus. Rock bream in the fed group increased in body weight, standard length, and condition factor, but these parameters decreased significantly for fish in the st...

OBJECTIVE To report the morphometric characteristics of ultrastructure inside A549 cells. METHODS A549 cells were processed for inverted microscopy and transmission electron microscopy (TEM). Cell images were obtained randomly using inverted microscopy and TEM. The morphometric parameters of ultrastructure were tested using precise morphometric techniques by Image-Pro Plus analysis software. ...

 Mahisefid, Rutilus frisii kutum , is a cyprinid fish which is distributed from Turkmenistan to Azerbaijan along the Caspian Sea. It is one of the economically important fish in the region. As part of the Iranian Fisheries Company’s policy to improve the stocks of this species, every year, fingerling of Mahisefid are released into the southern basin of the Caspian Sea. The main objective of thi...

Numerical characterization of animal body forms using elliptical Fourier decomposition may be a useful analytic technique in a variety of marine mammal investigations. Using data collected from the Weddell seal (Leptonychotes weddellii), we describe the method of body form characterization using elliptical Fourier analysis and demonstrated usefulness of the technique in photogrammetric mass-est...

Actinomycetes are inexhaustible producers of commercially valuable metabolites, are continually screened for beneficial compounds. The taxonomic and phylogenetic study of novel actinomycetes strains are mostly based on conventional methods and primary DNA structure of 16s rRNA. Although 16s rRNA sequence is well accepted in phylogeny studies, its secondary structures have not been widely used. ...

UNLABELLED In a beautifully descriptive paper, authors from Rio de Janeiro and San Francisco report a quantitative and qualitative histological analysis of spongiosal tissue in patients with bulbar urethral strictures. They found that stricture formation was characterised by major alterations in extracellular matrix features. OBJECTIVE To report a quantitative and qualitative histological ana...

The field of quantitative morphology has long been important in biological investigations. Various elements of an organism’s morphology, such as size and shape, are easily quantified, and standard methods for the analysis of these components exist (i.e., geometric morphometrics). However, methods for reliably quantifying textures and patterns are currently lacking. In this paper we propose a te...

This study proposed to morphologically analyze the adult human occipital condyle, estimate the bilateral differences, sexual dimorphism and compare with the available data. We conducted this study on hundred occipital condyles in fifty dry human skulls. The measurement was performed by the means of the vernier’s caliper on both sides of the skull. The parameters measured are length, width, heig...
