By means of a Q-banding technique, virtually every chromosome in two heteroploid mouse cell lines, RAG and MSWBS, has been identified. The origin of 60 to 80% of the chromosomes has been established; the remaining chromo somes can be identified as markers characteristic of the cell line. The extent of chromosome heterogeneity has been ex amined and compared in these two mouse tumor cell lines. ...

Rheumatoid arthritis and periodontitis are widely prevalent diseases and are characterized by tissue destruction due to chronic inflammation. Recently, there is growing evidence that the two diseases share many pathological features. This article reviews their clinical and biological links. However, there are only a limited number of studies in this area, which prevent us from offering clear ev...

Local perforator flaps have evolved over the time to provide complete and stable coverage of soft tissue defects. Technical advances and experience with the perforator flaps have allowed the harvest of local perforator flaps in a free style manner by offering greater freedom in flap selection. We have proposed a technical modification in the harvest of a perforator flap by relo-cating the perfo...

Nowadays laser is extensively used in various industrial, communicative, medical, and other fields. Using laser in medicine has enabled physicians to perform the most accurate and finest operations within few minutes. Non-observance of safety points during laser performance could be seriously harmful for the medical staff and the patient. Therefore, in order to prevent the possible damage of th...
