This study investigates the feasibility of using nano-thermal rod for deicing tunnel pavements in cold region. The heating performance of the nano-thermal rod was compared with that of carbon fiber heating wire under low voltage conditions. Experimental studies were conducted in a controlled environmental chamber to evaluate the effects of arrangement parameters (spacing, buried depth, input power) and environmental factors (ambient temperature and moisture) on heating rate and effectiveness.

Ceftriaxone upregulates GLT1 glutamate transporter in the brain and may have anti-CFC and anti-OCD effects. Twenty WZ-5HT rats were used to investigate the effects of ceftriaxone on obsessive-compulsive (OCD)-like behaviour in the marble-burying (MB) test, freezing behaviour in contextual fear conditioning (CFC) and expression of GLT1 protein in the hippocampus or amygdala using immunoblots. Fifteen DBA/2J mice were used in the MB test.

Article Synopsis
- Intramedullary straight nail fixation for proximal humeral fractures has several benefits over plating, including reduced soft-tissue damage, enhanced stability for complex fractures, and shorter surgery time for easier cases.
- The procedure involves positioning the patient in a beach-chair position, reducing the fracture using closed methods or percutaneously, and making a small incision near the acromioclavicular joint to insert a guide-pin for nail placement.
- After confirming the proper alignment via fluoroscopy, proximal and distal locking screws are inserted through a targeting jig, followed by irrigation and closure of the incision for postoperative care.

Background: The recommendation on whether to bury or expose the Kirschner wire (K-wire) for the management of fractures has still been controversial with inconsistent results in the published studies due to the potential issue associated with exposed K-wire is the heightened risk of infection, as it comes into direct contact with the external environment and air. This study aims to summarize the specific outcomes between buried and exposed K-wire for the management of hand and forearm fractures.
Methods: We conducted relevant literature searches on Europe PMC, Medline, Scopus, and Cochrane Library databases using specific keywords.
