Microbial transglutaminase (mTG) was used as a crosslinking agent in the preparation of gelatin sponges. The physical properties of the materials were evaluated by measuring their material porosity, water absorption, and elastic modulus. The stability of the sponges were assessed via hydrolysis and enzymolysis. To study the material degradation in vivo, subcutaneous implantations of sponges wer...

Intracellular imaging of pathologically relevant proteases can provide essential information for the accurate evaluation of disease stage and progression. However, the risks of degradation by nonspecific enzymes during transportation and poor cellular uptake limit the use of peptide-based molecular probes (PMPs) for in situ protease imaging. To overcome these obstacles, a self-protected nanoveh...

Ruditapes philippinarum is a member of the Veneridae family of marine bivalve molluscs. RPOI‑1 (Ruditapes philippinarum oligopeptide) is a tetrapeptide that can be extracted from Ruditapes philippinarum by means of enzymolysis. This study showed that RPOI‑1 strongly inhibits proliferation and induces apoptosis in DU‑145 human prostate cancer cells. When cells were treated with varying concentra...

In this study, high performance liquid chromatography (HPLC), ultraviolet (UV), thermagravimetric analyzer (TGA), pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS), and scanning electron microscope (SEM) were used as measurement techniques, contents of chemical composition, pyrolytic products, thermal stability, morphological characterization of Ginkgo biloba leaves (GBL) acted as the i...

This study aimed to identify the proteins that are differentially expressed in sera of multiple sclerosis (MS) patients, neuromyelitis optica (NMO) patients, and normal controls by using a two-dimensional gel electrophoresis (2-DE) assay. Serum samples were collected from the 3 groups, and total proteins were isolated and quantified by using the Bradford assay. The 2-DE and silver staining were...

Structural characterizations of the anti-complementary acidic heteroglycans, AAF IIb-2 and IIb-3, obtained from the leaves of Artemisia princeps pamp have been studied. AAF IIb-2 consists of rhamnose, xylose, arabinose, galactose, glucose and uronic acids (glucuronic acid and galacturonic acid) in the molar ratio of 7.6:7.6:13.0:10.9:3.0:57.9, and AAF IIb-3 consists of the same sugars in the ra...

Recent work (Berg, Rose, and Marvel, 1929-30) has shown that the essential amino acid, tryptophane, may be rendered unfit for supporting growth, either by benzoylation or by condensation with formaldehyde. The formaldehyde condensation product has been employed also by Jackson (1929) with a similar result. On the other hand, neither esterification with ethyl alcohol nor acetylation caused any d...

Although wheat (Triticum aestivum L.) pericarp starch granule (PSG) has been well-studied, our knowledge of its features and mechanism of accumulation and degradation during pericarp growth is poor. In the present study, developing wheat caryopses were collected and starch granules were extracted from their pericarp to investigate the morphological and structural characteristics of PSGs using m...

This study aims to explore the influence of hyaluronic acid (HA) on wound healing during xenogeneic porcine acellular dermal matrix (PADM) composite skin grafting. The results will facilitate the development of methods for improving graft contracture and poor elasticity of composite transplantation. Exogenous HA was added to composite PADM grafts and to thin autologous skin grafts during rabbit...
