High-adhesion stretchable electrodes are fabricated by utilizing a novel nanopile interlocking strategy. Nanopiles significantly enhance adhesion and redistribute the strain in the film, achieving high stretchability. The nanopile electrodes enable simultaneous monitoring of electromyography signals and mechanical deformations. This study opens up a new perspective of achieving stretchability and high adhesion for stretchable electronics.

Metal-organic frameworks (MOFs) have drawn increasing attentions as promising candidates for functional devices. Herein, we present MOF films in constructing memory devices with alcohol mediated resistance switching property, where the resistance state is controlled by applying alcohol vapors to achieve multilevel information storage. The ordered packing mode and the hydrogen bonding system of the guest molecules adsorbed in MOF crystals are shown to be the reason for the alcohol mediated electrical switching. This chemically mediated memory device can be a candidate in achieving environment-responsive devices and exhibits potential applications in wearable information storage systems.

Several lncRNAs from tissue, blood, and gastric juice have shown potential values in gastric cancer diagnosis or prognosis evaluation.

Long noncoding RNAs (lncRNAs) play an important role in cancer occurrence and development. However, there is largely unknown about lncRNAs significance in the diagnosis and treatment of gastric cancer. In our study, we focused on AC130710, one of lncRNAs. Gastric cancer tissues and adjacent tissues were gathered from 78 patients with gastric cancer. The AC130710 levels were detected by reverse transcription polymerase chain reaction (RT-PCR). Then, we further analyzed the association between AC130710 level and the clinicopathological factors of patients with gastric cancer. Finally, the molecular mechanism underling AC130710 highly expressed in gastric cancer cells was explored. The results showed that AC130710 in cancer tissues from patients with gastric cancer was significantly higher than those in adjacent noncancerous tissues (P < 0.05). Its expression level was significantly associated with tumor size (P = 0.013), tumor-node-metastasis (TNM) stages (P = 0.030), and distal metastasis (P = 0.018). AC130710 expression in MGC-803 was significantly higher than that in normal gastric mucosa cell line GES-1 (P < 0.001). Moreover, miR-129-5p may play an important role in the downregulation of AC130710 in gastric cancer cells. These results indicated that lncRNA-AC130710 may be a potential tumor marker for gastric cancer prognosis.
