Edible materials have attracted increasing attention because of their excellent properties including availability, biocompatibility, biological activity, and biodegradability. Natural polysaccharides, phenolic compounds, and proteins are widely used in tissue regeneration. To better characterize their healing effect, this review article describes the applications of edible materials in tissue regeneration including wound healing and bone tissue regeneration. As an introduction to the topic, their sources and main bioactive properties are discussed. Then, the mechanism by which they facilitate wound healing based on their hemostasis, antibacterial, anti‐inflammatory, and antioxidant properties is systematically investigated. Moreover, a more comprehensive discussion is presented on the approaches by which edible materials can be used as scaffolds or agents for the provision of the components of natural bones for regulating the level of osteogenesis‐related cytokines to enhance bone repair. Finally, the prospects of edible materials for tissue regeneration are discussed.

Gymnocorymbus ternetzi belongs to the genus Gymnocorymbus in the family Characidae, and is mainly distributed in southern Brazil. Herein, we report the complete mitogenome of G. ternetzi using Illumina sequencing data. The mitogenome is 17,999 bp in length and contains 13 protein-coding genes, 22 transfer RNA genes, and 2 ribosomal RNA genes. Phylogenetic analysis of G. ternetzi and 18 related species within Characidae indicates that G. ternetzi clusters within the family Characidae. The data provide useful genetic information for future studies on the taxonomy, phylogeny, and evolution of Characidae species.

An optical method was developed to monitor solubility of the polymer by taking advantage of reflection spectrum change of the dissolution tunable inverse opal photonic crystal. The dissolution tunable photonic bands of the polymer inverse opal photonic crystal were traceable to the chain motion of macromolecules. By observing the reflection spectrum change of the polystyrene inverse opal tip during solvent treatment, solubility of polystyrene was gotten.

Background Selective intrauterine growth restriction (sIUGR) affects about 10–15% of monochorionic (MC) twin pregnancies. The lncRNA profiles of placenta complicated with sIUGR are unknown. In the present study, the sIUGR-associated placental lncRNA expression was investigated using sequencing and confirmatory reverse transcriptase-quantitative polymerase chain reaction studies. Methods Placenta samples around the insertion region of the umbilical cord were collected from monochorionic twins complicated with (n = 9) or without sIUGR (control, n = 9). lncRNA and mRNA profile analysis was performed using transcriptome sequencing and validated by RT-PCR. Results A total of 30 lncRNAs were differentially expressed (17 up-regulated and 13 down-regulated) in the placenta of sIUGR cases compared with control cases. The differentially expressed lncRNAs were mainly involved in the mitogen-activated protein kinase signaling pathway (MAPK signaling pathway), ubiquitin proteasome pathway and angiogenesis pathway, which might be associated with the pathogenesis of sIUGR. Conclusions To the best of our knowledge, the findings of the current study have provided the first lncRNA profiles and the possible lncRNA regulatory networks of placental tissues complicated with sIUGR.
