Treatment of Post-Stroke Dysphagia with Repetitive Transcranial Magnetic Stimulation Based on the Bimodal Balance Recovery Model: A Pilot Study.

Background: Brain plasticity and functional reorganization are the main mechanisms of stroke rehabilitation and the theoretical basis for transcranial magnetic therapy. Bimodal balance recovery model suggests that the structural integrity of neural pathways affects the functional reorganization mode of brain recovery after stroke. The principal neural pathway that innervates swallowing is the corticobulbar tract (CBT).

ASPM promotes ATR-CHK1 activation and stabilizes stalled replication forks in response to replication stress.

ASPM is a protein encoded by () and is responsible for ensuring spindle position during mitosis and the symmetrical division of neural stem cells. We recently reported that ASPM promotes homologous recombination (HR) repair of DNA double strand breaks. However, its potential role in DNA replication and replication stress response remains elusive.

Study on AgInZnS-Graphene Oxide Non-toxic Quantum Dots for Biomedical Sensing.

In recent years, non-toxic quantum dot has caught the attention of biomedical fields. However, the inherent cytotoxicity of QDs makes its biomedical application painful, and is a major drawback of this method. In this paper, a non-toxic and water-soluble quantum dot AgInZnS-GO using graphene oxide was synthesized.

A nanoplatform with tumor-targeted aggregation and drug-specific release characteristics for photodynamic/photothermal combined antitumor therapy under near-infrared laser irradiation.

Due to their high biocompatibility, high spatial resolution, chromatographic capability, and adjustable size and morphology, magnetic nanoparticles have become the most promising nanomaterials for clinical application in noninvasive imaging and drug delivery for the treatment of malignant tumors. Herein, a novel magnetic nanoparticle coated with calcium carbonate was prepared and loaded with near-infrared drugs to be used as a multifunctional theranostic nanoplatform for the diagnosis and treatment of malignant tumors. Then, these drug-loaded nanoparticles were used for combined photodynamic/photothermal therapy by intravenous administration that was simultaneously guided by fluorescence/MR imaging.

A Fast and Highly Selective Nitrite Sensor Based on Interdigital Electrodes Modified With Nanogold Film and Chrome-Black T.

Nitrite is a toxic substance, when excessive nitrite enters the human body, it will be seriously harmful to human. At present, the detection methods of nitrite are complicated to operate and require expensive detection instruments. Therefore, an effective, fast and highly selective nanogold film interdigital electrode sensors that can detect nitrite easily and quickly is developed in the work.

Comparison of short-term outcomes following minimally invasive versus open Sweet esophagectomy for Siewert type II adenocarcinoma of the esophagogastric junction.

Background: Surgical resection is still the main treatment option for patients with resectable Siewert type II adenocarcinoma of the esophagogastric junction (AEG). This retrospective study evaluated the significance of minimally invasive Sweet esophagectomy (MISE) for the treatment of Siewert type II AEG.

Methods: We retrospectively evaluated 174 patients with Siewert type II AEG who received a Sweet esophagectomy in our center between October 2013 and September 2017.
