Therapeutic efficacy of intra-articular injection of human adipose-derived mesenchymal stem cells in a sheep model of knee osteoarthritis.

Background: Mesenchymal stem cells have great potential for repairing articular cartilage and treating knee osteoarthritis (KOA). Nonetheless, little is known about the efficacy of human adipose-derived mesenchymal stem cells (haMSCs) for KOA in large animal models.

Methods: This study evaluated the therapeutic efficacy of haMSCs in knee articular cartilage repair in a sheep model of KOA.

Thermal gradient ring for analysis of temperature-dependent behaviors involving TRP channels in mice.

There are a lot of temperature-sensitive proteins including transient receptor potential (TRP) channels. Some TRP channels are temperature receptors having specific activation temperatures in vitro that are within the physiological temperature range. Mice deficient in specific TRP channels show abnormal thermal behaviors, but the role of TRP channels in these behaviors is not fully understood.

TRPV3 in skin thermosensation and temperature responses.

Human skin, as a sophisticated sensory organ, is able to detect subtle changes in ambient temperature. This thermosensory capability is primarily mediated by temperature-sensitive TRP channels expressed in both sensory neurons and keratinocytes. Among these, TRPV3, which responds to warm temperatures and plays a crucial role in various skin functions, is particularly notable.

Speechreading Ability Affects Mandarin Tone Perception in Young Adults With Prelingual Hearing Impairment in China.

Purpose: This cross-sectional study explored how the speechreading ability of adults with hearing impairment (HI) in China would affect their perception of the four Mandarin Chinese lexical tones: high (Tone 1), rising (Tone 2), falling-rising (Tone 3), and falling (Tone 4). We predicted that higher speechreading ability would result in better tone performance and that accuracy would vary among individual tones.

Method: A total of 136 young adults with HI (ages 18-25 years) in China participated in the study and completed Chinese speechreading and tone awareness tests.
