Applying cationic waterborne polyurethane (CWPU) in the leather color-fixing process can improve the dyeing rate and enhance color fastness. However, under prolonged exposure to sunlight, CWPU will age and degrade and the leather will fade in color, become stiff and crack easily. In this study, an Ultraviolet absorber was introduced into cationic waterborne polyurethane (UVCWPU) and quaternary ammonium Lignosulfonate (QLS) was prepared by quaternization.

Low mechanical strength is still the key question for collagen hydrogel consisting of nanofibrils as hard tissue repair scaffolds with no loss of biological function. In this work, novel collagen nanofibrous hydrogels with high mechanical strength were fabricated based on the pre-protection of trisodium citrate masked Zr(SO) solution for collagen self-assembling nanofibrils and then further coordination with Zr(SO) solution. The mature collagen nanofibrils with d-period were observed in Zr(IV) mediated collagen hydrogels by AFM when the Zr(IV) concentration was ≥ 10 mmol/L, and the distribution of zirconium element was uniform.

Recently, increasing numbers of non-coding RNA have been uncovered in research. As a new class of non-coding RNA, circular RNA has been identified to be involved in various diseases including many cancers. The circular RNA ciRS-7 is reported to play critical roles in tumorigenesis.
View Article and Find Full Text PDFCircular RNA has been reported to be a new noncoding RNA which plays important roles in tumor progression. One of the most common functions of circular RNA is to regulate microRNA expression by acting as a microRNA sponge. However, the circular RNA expression profile and function remain mostly unclear in gastric cancer.

We aimed to investigate whether NLR was an independent predictor of cardiovascular or all-cause mortality in CKD patients with or without hemodialysis by performing a meta-analysis.
Methods: Pubmed, Embase, and Cochrane Library databases are systematically searched for relevant literature that investigated NLR and subsequent cardiovascular or all-cause mortality risk in CKD with or without dialysis.
