chronic periodontitis (cp) and peri-implantitis (pi) are multifactorial diseases of tooth and implant supporting apparatus. bacterial invasion and consequent host immune response seem to play a role in relevant pathogenesis. the structural differences between tooth and implant pose preferential biofilm colonization. this study was aimed to compare the prevalence of bacteria in cp and pi. clinic...
Resolving the phylogeny of the hominoid primates is a test case for molecular systematic methods because, by most genetic measures, humans, chimpanzees, and gorillas are very closely related. Recently, Sibley and Ahlquist (1984) applied DNADNA hybridization techniques to infer the hominoid phylogenetic tree with humans and chimpanzees closest. Templeton (1983, 1985) argues rather that the chimp...
Among vertebrates, most of the fishes are unique for the lack of acrosome in their spermatozoa. The sperm enters the egg through micropyle of the egg. This has facilitated heterologous fertilization in many fishes and led to hybridization and polyploidization. Hybridization is performed both in the nature and domesticated fishes. Today, some of the hybrids have high growth rate than their paren...
The genomic in situ hybridization (GISH) has been used to identify euploidy and aneuploidy in segregation generations of various plants. In this study, the GISH with minor modifications including, slide preparation of putative secondary Tritipyrum (F2) root meristemic cells, labeled genomic DNA of Thinopyrum bessarabicum by fluorescein 12-dUTP nucleotide as probe, genomic DNA of Thinopyrum bess...

Background: Lymphocytes of Fanconi anemia (FA) show an increased sensitivity to the alkylating agents such as mitomycin C (MMC), but their responses to gamma-irradiation is controversial. The extent of DNA damage in leukocytes of FA patients following irradiation and MMC treatment was studied at cellular and single chromosome level. Methods: DNA damage induced by gamma-rays and MMC was measure...
