Scanning tunneling microscope (STM) is a renowned scientific tool for obtaining high-resolution atomic images of materials. Herein, we present an innovative design of the scanning unit with a compact yet powerful inertial piezoelectric motor inspired by the Spider Drive motor principle. The scanning unit mainly consists of a small 9 mm long piezoelectric tube scanner (PTS), one end of which is coaxially connected to the main sapphire body of the STM.

We present the design and performance of a novel scanning tunnelling microscope (STM) operating in a cryogen-free superconducting magnet. Our home-built STM head is compact (51.5 mm long and 20 mm in diameter) and has a single arm that provides complete openness in the scanning area between the tip and sample.

Objective: To reveal the efficacy and possible mechanism of electroacupuncture at Zusanli (ST36) on injured skeletal muscle induced by jumping load.

Methods: In the present study, female Sprague-Dawley rats were randomly divided into four groups with 6 of each, including normal control group (NC), jumping-induced muscle injury model group (JI), JI with electroacupuncture stimulation treatment group (EA), and JI with non-electroacupuncture stimulation group (NEA). Transmission electron microscopy, transcriptome sequencing and analysis, prediction of protein interaction networks, real-time polymerase chain reaction verification, and Western blotting were performed on the gastrocnemius muscle of ipsilateral lower limbs.

Background: Traumatic cervical spinal cord injury with subaxial fracture and dislocation not only indicates a highly unstable spine but can also induce life-threatening complications. This makes first aid critically important before any definitive operative procedure is undertaken. The present study analyzes the various first aid measures and operative procedures for such injury.

Article Synopsis
  • Retinoic acid (RA) promotes differentiation in human medulloblastoma cells (Med-3) but does not kill them, indicating a limited effect on these tumors.
  • A study tested the effects of RA and cisplatin (CP), both individually and in combination, on cell growth and death patterns in Med-3 cells, revealing that while RA and CP alone could inhibit growth, they rarely caused apoptosis.
  • Combining half doses of RA and CP led to significant apoptosis in the cancer cells, suggesting that RA enhances the sensitivity of Med-3 cells to chemotherapy, which could be a promising treatment strategy for medulloblastomas.
