The green seaweed relies on associated bacteria for morphogenesis and is an important model to study algal-bacterial interactions. -associated bacteria exhibit high turnover across environmental gradients, leading to the hypothesis that bacteria contribute to the acclimation potential of the host. However, the functional variation of these bacteria in relation to environmental changes remains unclear.

Background: Oral microbiome homeostasis is important for children's health, and microbial community is affected by anesthetics. The application of anesthetics in children's oral therapy has become a relatively mature method. This study aims to investigate the effect of different anesthesia techniques on children's oral microbiota.

Background: Keloids are disfiguring, fibrotic scar-like lesions that are challenging to treat and commonly recur after therapy. A deeper understanding of the mechanisms driving keloid formation is necessary for the development of more effective therapies. Reduced vitamin D receptor (VDR) expression has been observed in keloids, implicating vitamin D signaling in keloid pathology.

The effects of vitamin D and vitamin A in immune cells are mediated through the vitamin D receptor (VDR) and retinoic acid receptor (RAR), respectively. These receptors share the retinoid X receptor (RXR) co-factor for transcriptional regulation. We investigated the effects of active vitamin D (1,25(OH)D) and 9-cis retinoic acid (9cRA) on T helper (T)1 and T2 cytokines and transcription factors in primary human blood-derived CD4 T cells.
