Percutaneous radiofrequency ablation of liver cancer in the hepatic dome using the intrapleural fluid infusion technique
TL;DR: Intrapleural fluid infusion improves ultrasonographic visualization of tumours in the hepatic dome with intrapleural infusion with the aim of assessing the safety and long‐term efficacy of ultrasonographically guided percutaneous radiofrequency ablation for tumour treatment with intraplesural infusion.
17beta-Estradiol inhibits the voltage-dependent L-type Ca2+ currents in aortic smooth muscle cells
TL;DR: The results suggest that 17β-estradiol may play a role in regulating vascular tone, selectively by inhibiting the voltage-dependent L-type Ca2+ current in vascular smooth muscle cells.
MO39-5 Analysis of perioperative chemotherapy-mediated genomic changes in gastric cancer
Kou Ikegame,Hayato Omori,Masao Hada,Hideki Watanabe,Atsushi Takano,Ayako Kimura,Masayuki Inoue,Kazusige Furuya,M. Yasutome,Yoshiaki Miyasaka,Yuji Imuro,H. Nakagomi,Kenji Amemiya,Yosuke Hirotsu,Masao Omata +14 more
TL;DR: This study investigates genomic changes in gastric cancer patients undergoing perioperative chemotherapy, aiming to clarify the molecular alterations and their impact on treatment resistance, using The Cancer Genome Atlas (TCGA) as a reference.
MO15-4 Challenges for lung cancer screening using blood samples – methylome analysis of plasma-derived cell-free DNA
Takahiro Nakagomi,Rumi Higuchi,Kenji Amemiya,Yosuke Hirotsu,Taichiro Goto,Hitoshi Mochizuki,Masao Omata +6 more
TL;DR: Researchers developed a lung cancer screening method using plasma-derived cell-free DNA methylome analysis, aiming to improve sensitivity and specificity, which are currently insufficient for clinical application, to detect tumor-specific methylation abnormalities.
