current research in order to identify neo tectonic activity of the ziyarat basin has been made on the northern slopes of the eastern alborz in south-gorgan and using the index of morpho tectonic and tectonic evidence in the area. in this regard, the 6 morphological parameters were calculated and the results are analyzed. the overall results of these features, as indicators of the relative activ...

The special property of stem cells is that their development is asymmetric. They give rise both to cells that are identical to themselves and to cells that are different. The mechanism that provides this asymmetry may be intrinsic or extrinsic. Such mechanisms are considered within the context of other systems where asymmetric development occurs. The specification of mating types in yeast provi...

In the study of interphase chromosome organization, genome-wide chromosome conformation capture (Hi-C) maps are often generated using 2-dimensional (2D) monolayer cultures. These 2D cells have morphological deviations from cells that exist in 3-dimensional (3D) tissues in vivo, and may not maintain the same chromosome conformation. We used Hi-C maps to test the extent of differences in chromoso...

Food preservatives are unswervingly being used for prolonging the shelf life of food, often to increase aroma, taste and quality by food packaging industry. These pivotal in protecting from degradation deterioration micro-organisms. Two most commonly preservatives, viz. sodium nitrite (NaNO2) Monosodium glutamate (MSG) have been evaluated using root tips Allium cepa. Cytological studies plants ...

Fluctuating asymmetry (FA) can be defined as an organism's deviation from perfect bilateral symmetry. FA has been of interest to evolutionary biologists as it may be indicative of the ability of an individual to express its genotype in a stable manner. Asymmetry has been shown to correlate with success in both intra- and inter-sexual selection in various species, including humans. A growing bod...

Centromere-near gain of copy number can be induced by intra- or inter-chromosomal rearrangements or by the presence of a small supernumerary marker chromosome (sSMC). Interestingly, partial trisomy to hexasomy of euchromatic material may be present in clinically healthy or affected individuals, depending on origin and size of chromosomal material involved. Here we report the known minimal sizes...

INTRODUCTION Lateral cephalometric radiographs are traditionally required for orthodontic treatment, yet rarely used to assess asymmetries. OBJECTIVE The objective of the present study was to use lateral cephalometric radiographs to identify existing skeletal and dentoalveolar morphological alterations in Class II subdivision and to compare them with the existing morphology in Class I and II ...

We present a structural and photometric analysis of 42 elliptical/lenticular galaxies in (E/S0 + S) pairs observed in the BV RI color bands. The aim of the analysis is to empirically determine the effects of interactions on their morphology, structure and stellar populations as seen from the light concentration (C), asymmetry (A), and clumpiness (S) parameters. We further compare these values t...

The primary objective of the present study was to evaluate the agreement between the dominant leg (DL) (determined subjectively) and the stronger leg (SL) (determined via a functional test) in a group of basketball and volleyball players. The secondary objective was to calculate lower limb neuromuscular asymmetry when comparing the DL vs the non-dominant leg (NDL) and the SL vs the weaker (WL) ...

BACKGROUND Lameness is a common problem in modern swine husbandry. It causes welfare problems in affected pigs as well as financial problems for farmers. To minimize these negative consequences of lameness, new treatment and prevention strategies need to be developed and validated using objective and quantitative measurement techniques. An example of such a putative diagnostic tool is the use o...
