Chromosome number and karyotype of Astragalus stereocalyx Bornm. (Milk-vetch) in the section Stereocalyx Bornm. distributing naturally in Turkey were analyzed in detail. This species is endemic to Turkey and growing in Eskişehir and Konya provinces. Squash preparation method was used for chromosome study in this species. The somatic chromosome number was determined as 2n = 16 in A. stereocalyx....

The chromosome number and karyotype analysis of male trees of Pistacia vera L. was investigated to determine the sex chromosomes. For karyological determination, root tips were obtained from in vitro derived shoots. Afterwards fifty plates of mitosis were used for the karyotyping, the five best metaphase plates were measured for karyotype analysis, karyogram and idiogram. The conclusions obtain...

Motion analysis plays an important role in studing activities or behaviors of live objects in medicine, biotechnology, chemistry, physics, spectroscopy, nanotechnology, enzymology, and biological engineering. This paper briefly reviews the developments in this area mostly in the recent three years, especially for cellular analysis in fluorescence microscopy. The topic has received much attentio...

Aneuploidies cause gene-dosage imbalances that presumably result in a generalized decreased developmental homeostasis, which is expected to be detectable through an increase in fluctuating asymmetry (FA) of bilateral symmetric traits. However, support for the link between aneuploidy and FA is currently limited and no comparisons among different aneuploidies have been made. Here, we study FA in ...

BACKGROUND Thousands of infants are born each year with chromosomal abnormalities that severely impact physical and mental development. Among common genetic disorders are Down syndrome (trisomy 21) and sex chromosomal disorders. OBJECTIVES Evaluation of guidelines used for prenatal diagnosis of Down syndrome (DS) as well as sex chromosomal disorders including interphase Fluorescent In Situ Hy...

Given article considers the problem of automation chromosome pathology recognition. Overview existing publications in adjacent topics has shown need for further research due to scientific relevance and lack groundwork. The application domain been considered - both theoretical aspects recognition diagnostics process itself. Classification main abnormalities performed. A formal algorithm derived ...

The karyotypic characteristics of   chub, Squalius cephalus have been investigated by examining metaphase chromosomes spreads obtained from gill and kidney tissues. The fish used in the study were caught with fishing nets from Dumlu Stream, one of the main tributaries of the Karasu River. The live fish were transported to the laboratory,  kept in a well aerated aquarium before analysis and then...
