Abstract Share this page

The Temporal bone is a valuable resource to study ear diseases and to teach anatomy to both undergraduate and postgraduate medical students. It is one of the most complicated bones of the skull. Methods of dissecting the middle ear have been described in the text books of Anatomy [1], Pathology and Forensic Medicine [2,3]. Those methods mainly involve the piece meal removal of the bone to expose the tympanic antrum and opening the middle ear cavity which requires a lot of time and expertise. The Present study was conducted on 200 Temporal Bones of 100 unidentified cadavers during Medico-legal Post-mortem Examination. We have devised a new and a very simple method to dissect the temporal bone. Dissection was carried out with the help of a single sharp edged chisel cut named as Cobbler’s Cut that quickly exposes the middle ear cavity and helps in the easily procurement of the ear ossicles (Malleus, Incus & Stapes). It was found to be successful in 86% of the cases for the easy procurement of the complete set of ear ossicles bilaterally. The cadaveric ear ossicles could be of great help for the research purposes in Forensic Medicine and ENT.

    Classically, the 3’untranslated region (3’UTR) is that region in eukaryotic protein-coding genes from the translation termination codon to the polyA signal. It is transcribed as an integral part of the mRNA encoded by the gene. However, there exists another kind of RNA, which consists of the 3’UTR alone, without all other elements in mRNA such as 5’UTR and coding region. The importance of independent 3’UTR RNA (referred as I3’UTR) was prompted by results of artificially introducing such RNA species into malignant mammalian cells. Since 1991, we found that the middle part of the 3’UTR of the human nuclear factor for interleukin-6 (NF-IL6) or C/EBP gene exerted tumor suppression effect in vivo. Our subsequent studies showed that transfection of C/EBP 3’UTR led to down-regulation of several genes favorable for malignancy and to up-regulation of some genes favorable for phenotypic reversion. Also, it was shown that the sequences near the termini of the C/EBP 3’UTR were important for its tumor suppression activity. Then, the C/EBP 3’UTR was found to directly inhibit the phosphorylation activity of protein kinase CPKC in SMMC-7721, a hepatocarcinoma cell line. Recently, an AU-rich region in the C/EBP 3’UTR was found also to be responsible for its tumor suppression. Recently we have also found evidence that the independent C/EBP 3’UTR RNA is actually exists in human tissues, such as fetal liver and heart, pregnant uterus, senescent fibroblasts etc. Through 1990’s to 2000’s, world scientists found several 3’UTR RNAs that functioned as artificial independent RNAs in cancer cells and resulted in tumor suppression. Interestingly, majority of genes for these RNAs have promoter-like structures in their 3’UTR regions, although the existence of their transcribed products as independent 3’UTR RNAs is still to be confirmed. Our studies indicate that the independent 3’UTR RNA is a novel non-coding RNA species whose function should be the regulation not of the expression of their original mRNA, but of some essential life activities of the cell as a whole.
