Ultrasonic effects on molecular weight degradation, physicochemical and rheological properties of pectin extracted from Premna microphylla Turcz.

The high molecular weight and poor solubility of pectin extracted from Premna microphylla Turcz (PEP) limits its application. Therefore, in this paper, the degradation effects of PEP under ultrasound irradiation and the influences of ultrasonic on the PEP processing characteristics were investigated. The results indicated that the M of PEP decreased significantly with a narrow distribution after ultrasonic treatment.

[Genome-wide identification, phylogenetic analysis and expression profiling of the MKK gene family in ].

Mitogen-activated protein kinase kinase (MAPKK or MKK) is an important component of the MAPK cascade, which plays important roles in plant growth and development as well as in various stress responses. At present, the MKK gene family has been identified in a variety of plants, but there has been no systematic study in Cruciferous plant . To explore the evolution and function of the MKK gene family in , 16 genes were identified from the genome by genome-wide analysis, and they were distributed on 10 chromosomes of .

Diverse Lanthanide Coordination Polymers with 3,3'-Dimethylcyclopropane-1,2-dicarboxylate Ligand: Synthesis, Crystal Structure, and Properties.

In an attempt to investigate the influence of many variables on the synthesis of lanthanide coordination polymers (Ln-CPs) assembled from the ligand 3,3-dimethylcyclopropane-1,2-dicarboxylic acid, three different Ln-CPs with formulae [La(μ-dcd)(μ-O)(H)] (), [Gd(μ-dcd)(HO)] (), and [Gd(μ-OH)(μ-dcd)(μ-ac)(HO)] () (dcd = 3,3-dimethylcyclopropane-1,2-dicarboxylate, ac = acetate) have been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, thermal analysis, powder X-ray diffraction, and single X-ray diffraction techniques. represents the first report of the three-dimensional (3D) Ln-CPs based on nonanuclear lanthanide clusters, although it shows extremely low gas uptakes. exhibits one of the previously reported 3D lanthanide wheel cluster-like frameworks.

Effects of intermedin on dorsal root ganglia in the transmission of neuropathic pain in chronic constriction injury rats.

Neuropathic pain is a common and severely disabling state that affects millions of people worldwide. The P2X3 receptor plays a crucial role in facilitating pain transmission. Intermedin (IMD), which is also known as adrenomedullin 2 (AMD2) is a newly discovered hormone that is a member of the calcitonin/calcitonin gene-related peptide family.
