Novel Co-MOF-doped gelatin/agar intelligent film for beef freshness visual tracking based on the structural change of ZIF-67 under ammonia etching effect.

It is an important task to construct intelligent packaging for meat freshness monitoring with good color stability and indication function. Herein, cobalt-based metal-organic framework nanomaterials (Co-MOF, ZIF-67) with antimicrobial and ammonia-sensitive properties were successfully synthesized and added into gelatin/agar (GA) matrix to develop highly stable intelligent films (GA/ZIF67). The incorporation of ZIF-67 nanoparticles enhanced the hydrophobicity (water contact angle >90°) and UV-blocking properties (close to 0.

[Progress in the study of the surgical management of Crohn disease based on the mesenteric concept].

In recent years, with the deepening of mesentery research, it is found that its blood vessels, nerves, lymphoid tissue, adipose tissue and other structures play an important role in the occurrence and development of Crohn disease, and the degree of lesion is related with the disease process, surgical difficulty, the occurrence of intraoperative complications and postoperative recurrence. The optimal surgical strategy of Crohn disease based on mesenteric involvement has received great attention. Multiple retrospective studies found that extended mesenteric resection and Kono-S anastomosis potentially could reduce the rate of postoperative recurrence.

USP25 stabilizes STAT6 to promote IL-4-induced macrophage M2 polarization and fibrosis.

As a leading cause of morbidity and mortality, fibrosis is the common pathway of various chronic inflammatory diseases in organs and causes death in a large number of patients. It can destroy the structure and function of organs and ultimately lead to organ failure, which is a major cause of disability and death in many diseases. However, the regulatory mechanism of organ fibrosis is not well clear and the lack of effective drugs and treatments, which seriously endangers human health and safety.

Nitrogen-Fixing and : Two Novel Species from Plant Rhizospheres.

Two strains, M1 and H32 with nitrogen-fixing ability, were isolated from the rhizospheres of different plants. Genome sequence analysis showed that a (trogen ixation) gene cluster composed of nine genes () was conserved in the two strains. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strains M1 and H32 are members of the genus .

Molecular and biological characterization of infectious full-length cDNA clones of two viruses in Paris yunnanensis, including a novel potyvirus.

Paris yunnanensis, also named as Rhizoma Paridis in the Chinese Pharmacopeia, is a perennial Chinese medicinal herb commonly grown in Southwest China. However, several viruses have been found infecting this plant in recent years. Using high-throughput sequencing (HTS) and Sanger sequencing, this study obtained the complete genome sequences of three capillovirus isolates and one potyvirus isolate.
