The rising global demand for palm oil and its associated products has led to increased numbers of palm oil refineries with its attendant effluent discharge. Many researches have confirmed the ecological disruptive potentiality of Palm Oil Mill Effluent (POME), still further attention has to be directed at POME’s potential genotoxicity. The present study has made physico-chemical and genotoxicit...

this study was conducted to determine the location of dna segment with homology to the rat conserved genomic dna in human chromosomes. the labeled rat genomic dna was hybridized with normal human (male) metaphases. the study of 74 metaphases after fluorescence in situ hybridization showed 371 twin-spot signals on human chromosomes. statistical analysis indicated that the specific accumulation o...

To date, our understanding of how DNA is packaged in the cell nucleus, condensed from chromatin into chromosomes, and organized throughout cycle remains sparse. Three dimensional (3D) ultrastructural imaging an important tool for unravelling organizational structure chromosomes. For large volume 3D biological samples, serial block-face scanning electron microscopy (SBFSEM) has been applied, whe...

objective: polymorphism of the size of heterochromatin region of chromosomes has been well documented in human genome and it consists of dna sequences that are not transcribed. the prime aim of the present study was to evaluate the heterochromatin polymorphism associated with chromosomes in leukemic patients. materials and methods: the study was conducted on 35 consecutive leukemic patients and...

because of limits in applicable karyological techniques and also the presence of a large number of small chromosomes in penaiedae family, the study on the number, structure, and the formula of the chromosomes in these shrimps is difficult. the present cytogenetic study was conducted on penaeus (fenneropenaeus) merguiensis native to persian gulf and oman sea by preparing spreads from various ear...

The Organic Bound Tritium (OBT) amount in the body may induce changes in the evaluation of the internal exposure to tritium, due to its different retention time relative to HTO. OBT measurements for urine are not performed routinely, mainly because of the lengthy work needed in preparation of the samples, when using the standard oxygen combustion method. A simpler and more rapid method based on...

Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...
