Laparoscopy-assisted gastrectomy with D2 lymph node dissection for advanced gastric cancer without serosa invasion: a matched cohort study from South China

World Journal of Surgical Oncology, 2013
Background Gastric cancer is a common malignancy worldwide and a common cause of death from cancer. Despite recent advances in multimodality treatment and targeted therapy, complete resection remains the only treatment that can lead to cure.

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

Advanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...

Helicobacter pylori-negative Gastric Cancer

The Korean Journal of Helicobacter and Upper Gastrointestinal Research, 2017
Although Helicobacter pylori is considered the main etiological factor in gastric cancer, at least 5.4% of gastric cancer cases in South Korean patients are H. pylori-negative. However, false-negative H. pylori results should be considered.
