The analysis of the balance elastase (MMP-2, MMP-9) and TIMP-4 was performed in order to determine their involvement pathogenesis NEC. A progressive duration NEC with sepsis is accompanied by increased serum concentrations MMP-9, MMP-2 TIMP-4. Increases MMP-2>503 ng/ml, MMP-9>812 ng/ml TIMP-4>1404 can be regarded as statistically significant predictors fatal outcome proposed method for...

Background Around 8–10% of individuals over 50 years age present interstitial lung abnormalities (ILAs), but their risk factors are uncertain. Methods From 817 recruited in our ageing programme at the Mexican National Institute Respiratory Diseases, 80 (9.7%) showed ILAs and were compared with 564 same cohort normal high-resolution computed tomography to evaluate demographic functional differen...

background: current treatments for joint diseases are moderately successful, but unfortunately are associated with significant side effects. this study was undertaken to investigate the combination effects of il-4 and prednisolone on tissue characteristics and production of matrix metalloproteinase-1(mmp-1) in il-lα-treated bovine nasal cartilage (bnc) explants. methods: bnc explants were cultu...

An alginate (named P1) prepared from Sargassum fusiforme has been proven to have significant anti-photoaging activity in our previous study. In this study, lyase was used obtain P1 hydrolysates with different molecular weights, and their structural characteristics were compared. Results showed that lyases could rapidly degrade the weight of slightly changed its chemical composition. Fourier tra...

In situ hydrogelation of injectable precursors upon biological stimulus is relevant to generate hydrogels under mild conditions and, potentially, at a side interest. Here, it shown that hydrolytic enzymes can be used initiate the formation covalent hydrogel networks, realizing cleavage-leading-to-gelation strategy. For this purpose, two-component system used, consisting 4-arm polyethylene glyco...

background: previous studies have shown that some cytokines have protective effects on cartilage in joint diseases. in the current study, effects of il-4 against morphological changes and tissue degradation induced by il-1α on bovine nasal cartilage (bnc) explants were investigated. methods: fresh bnc samples were prepared from a slaughterhouse under sterile conditions. bnc explants culture was...

Matrix metalloproteinase-9 (MMP-9) plays a central role in the progression of the cancer. While a large number of studies have contributed to our understanding of the molecular mechanisms responsible for upregulating MMP-9 gene expression in normal and cancer cells, our knowledge on the signals that suppress MMP-9 expression is much more limited. Here, we report that EGF and BMP-4 cooperate to ...
