PURPOSE To further improve the advantages of minimally invasive surgery, single port laparoscopic techniques continue to be developed. We report our initial experience with single port laparoscopic appendectomy (SPLA) in children and compare its outcomes to those of conventional laparoscopic appendectomy (CLA). METHODS Clinical data were prospectively(More)
Expression of hTERT has been recognized an important factor in cellular aging and immortalization. Therefore, to analyze regulatory mechanism of hTERT expression, we investigated the CpG methylation pattern of the hTERT promoter as an epigenetic mechanism and its implication in transcriptional regulation of hTERT using tissues of colorectal carcinoma. As a(More)
Tumor recurrence is a leading cause of cancer mortality. Therapies for recurrent disease may fail, at least in part, because the genomic alterations driving the growth of recurrences are distinct from those in the initial tumor. To explore this hypothesis, we sequenced the exomes of 23 initial low-grade gliomas and recurrent tumors resected from the same(More)
