The semantic system is a core component underlying many cognitive functions, and its deterioration can lead to various behavioral deficits. The Pyramids and Palm Trees Test (Howard & Patterson, 1992) and the Kissing and Dancing Test (Bak & Hodges, 2003) are among the most widely used semantic assessments, and they have been adapted into many languages and for many populations. We adapted these tests to the Mainland Chinese population by adopting culturally appropriate items and collecting normative data in healthy Chinese participants. In addition, accumulating research has shown that semantic representations have multidimensional structures that include various types of knowledge, and in the Pyramids and Palm Trees Test mainly evaluates associative relationships. Therefore, we developed additional tests to examine three other aspects of semantic knowledge: taxonomic, functional, and manipulative. We found significant correlations among all tests in healthy participants. Moreover, the level of education and age affected performance on the tests of associative relationships, taxonomic relationships, and manipulation similarity. [ABSTRACT FROM PUBLISHER]

Medical gases play an important role in the pathophysiology of human diseases and have received extensive attention for their role in neuroprotection. Common pathological mechanisms of spinal cord injury include excitotoxicity, inflammation, cell death, glial scarring, blood-spinal cord barrier disruption, and ischemia/reperfusion injury. Nitric oxide and hydrogen sulfide are important gaseous signaling molecules in living organisms; their pathological role in spinal cord injury models has received more attention in recent years. This study reviews the possible mechanisms of spinal cord injury and the role of nitric oxide and hydrogen sulfide in spinal cord injury., (Copyright © 2024 Copyright: © 2024 Medical Gas Research.)
