We analyzed by different cytochemical and immunocytochemical approaches the biochemical compositon of coiled bodies in three different cultured cell lines. Coiled bodies are stained by the AgNOR staining method and by the EDTA regressive staining method preferential for ribonucleoprotein (RNP). Using the in situ polyadenylate nucleotidyl transferase-immunogold technique or anti-RNA antibodies, we decisively demonstrated the presence of appreciable amounts of RNA in coiled bodies. Neither the in situ terminal deoxynucleotidyl transferase-immunogold technique nor anti-DNA antibodies revealed any DNA in coiled bodies. Coiled bodies thus appear as distinct regions of cell nuclei involved in some steps of RNA metabolism but not directly in RNA synthesis. Their relationships with the dense fibrillar component of the nucleolus and with interchromatin granule clusters are discussed. [less ▲]

The fine structure of the insect Sf9 cell nucleolus has been investigated by means of different cytochemical and immunocytochemical techniques at the electron microscope level. Apart from a few perinucleolar condensed chromatin clumps, the insect cell nucleolus comprises two compartments. The first of these consists of a roundish compact zone formed of fibrillar material. The other is composed of fibrillar and granular structures organized into a network separated by interstitial spaces. But, unlike mammalian cell nucleoli, any fibrillar center has been observed in the Sf9 cell nucleolus, even after actinomycin D treatment. We also show that the compact fibrillar zone of Sf9 cell nucleoli contains silver-stainable material and DNA. In actinomycin D-treated cells, a preferential contact of this compact fibrillar zone with condensed chromatin has been visualized. Finally, silver-stainable material has been found to persist throughout the whole mitosis. These results suggest that the compact fibrillar zone at the insect Sf9 cell nucleolus should, at least partly, correspond to the fibrillar center of mammalian cell nucleoli. [less ▲]

Introduction: There are numerous drug-drug interactions (DDIs) related to cardiovascular medications and many of these are mediated via the cytochrome P450 (CYP) system. Some of these may lead to serious adverse events and it is, therefore, essential that clinicians are aware of the important interactions that occur. Areas covered: An extensive literature search was performed to analyze the CYP-mediated cardiovascular DDIs that lead to a loss of efficacy or potential toxicity. Cardiovascular drugs may be victims or act as perpetrators of DDIs. The paper analyzes CYP-mediated drug interactions concerning anticoagulants, antiplatelet agents, antiarrhythmics, beta-blockers, calcium antagonists, antihypertensive medications, lipid-lowering drugs and oral antidiabetic agents. Expert opinion: Cardiovascular DDIs involving the CYP system are numerous. Additionally, the spectrum of drugs prescribed is constantly changing, particularly with cardiovascular diseases and it is not necessarily the case that drugs that had shown safety earlier will always show safety. Clinicians are encouraged to develop their knowledge of CYP-mediated DDIs so that they can choose safe drug combination regimens, adjust drug dosages appropriately and conduct therapeutic drug monitoring for drugs with narrow therapeutic indices.

After conjugation between Chlamydomonas gametes of opposite mating type, a transient dikaryon is formed. The two nuclei fuse within 4-6 hr after mating. The young diploid zygote differentiates into dormant zygospore competent to complete meiosis, or more rarely (2-10% of cases) it undergoes mitosis to produce a stable diploid progeny. We here bring genetical, biochemical, and cytological evidence that among the mitotic zygotes, a large proportion of them undergo cytokinesis without fusion of the nuclei - a process that has been termed "cytoduction." By using appropriate genetic markers, haploid cytoductants that possess the nuclear genotype of one parent and the chloroplast marker of the other parent can easily be isolated. Genetical analysis and hybridization experiments moreover show that many haploid cytoductants transmit the chloroplast DNA molecules of both parents and that, as in diploids, these DNA copies occasionally recombine. This process of cytoduction extends the life cycle of Chlamydomonas and provides new tools for its genetic analysis. [less ▲]

DNA histograms were oblained by flow cytometry for 39 human prostate carcinomas (27 total proslatectomy specimens, 5 biopsies and 7 transuretral resections). The study was performed on formalin-fixed and paraffin-embedded. material. In this report, ploidy index did not seem to be a good marker of prognosis as no significant variation in ploidy was found neither among the different stages nor among the different Gleason categories. Proliferative index of the tumors seemed to be a more sensitive parameter; a significant relation was observed between proliferative index and stage of the tumor. The authors discuss these results under the light of previously reported observations. [less ▲]

Cytogenetic analysis of rat hepatocarcinomas obtained after diethylnitrosamine (DEN) exposure showed a wide variety of numerical and structural chromosomal changes: 53 of 86 hepatocellular carcinomas showed at least one recurrent chromosomal aberration. Some of these recurrent changes occurred in several tumors. Chromosomes 1, 3, 11, and 12 were abnormal in more than 30% of the carcinomas; chromosomes 2, 4, 5, and 10 were abnormal in 10%. Moreover, chromosomes 1 and 10 were generally lost or deleted and chromosome 3, 4, and 11 were very often gained. The most frequent anomaly was loss of chromosome 1 which was observed in 35% of the tetraploid cell populations. The occurrence in several tumors of recurrent chromosomal rearrangements as well as various repeated aneuploidies strongly suggests that these anomalies are implicated in the process of rat hepatocarcinogenesis induced by DEN treatment.

A normal chromosome complement is essential for normal fertility. Chromosome aberrations – numerical or structural – may lead to a range of deformities and defects that can be physical and/or physiological. Irrespectively, aberrations result in complete loss of fertility or reduced fertility in stallions. They lead to the production of abnormal gametes that contribute to early embryonic deaths. Moreover, viable offspring from such gametes may carry the same chromosomal abnormality and have similar fertility problems. Economic losses incurred due to reduced stallion fertility or infertility is huge. Cytogenetic analysis is a simple and straightforward approach to ensure that the animals have a normal chromosome complement. To protect the economic interests of horse owners, breeders, prospective buyers, insurance companies, etc., the equine industry is strongly encouraged to mandate cytogenetic analysis of all breeding animals at an early age. The relatively inexpensive practice will also prevent the spread of chromosome aberrations as is expected from the progenies of the A P Valentine – a fairly successfully horse on the race track – and similar other carriers of abnormalities.

Described in the present paper is a cytogenetic study of bovine oocytes matured in vitro. The cumulus-oocyte complexes (COC), punctured from ovaries recovered in a local slaughterhouse, were classified into 3 groups according to follicular diameter 1 to 4mm, 5 to 8mm and 9 to 13 mm. Metaphases available for observation were classified as metaphase I, haploid and diploid metaphase II. High levels of haploid metaphases II (90.6, 86.9 and 94.4 %) among the 3 groups of follicular sizes indicated successful meiotic resumption during in vitro maturation and suggested that cytoplasmic maturation may be responsible for low developmental rate after IVM, IVF and in vitro development (IVD).
