The influences of short chain branching (SCB) and molecular weight (Mw) of low density polyethylene (LDPE) on its melt miscibility with polypropylene (PP) were investigated by rheological techniques. Rheological measurement and different data-treatment techniques as well as rheological models suggest that blends of PP with LDPE of high SCB (22 CH3/1000 C) are miscible at all compositions. Howev...

Type IV collagenase matrix metalloproteinases (MMPs), especially MMP-2 and MMP-9, have been found to promote invasion and metastasis of malignant tumors. Extracellular matrix (ECM) degradation by MMPs and increased expression of MMPs in cancer cells and tumor microvascular endothelial cells make MMPs an attractive target for cancer. Focused on a common pathomechanism of cancer growth and invasi...

Endothelin-1 (ET-1) is one of the most potent vasoconstrictors known to date. While its plasma or serum concentrations are elevated in some forms of experimental and human hypertension, this is not a consistent finding in all forms of hypertension. Matrix metalloproteinases -2 and -9 (MMP-2 and MMP-9), which degrade collagen type IV of the vascular basement membrane, are responsible for vascula...

We studied 55 patients with stage-IIB osteosarcoma around the knee with respect to the expression of matrix metalloproteinase (MMP)-9 in the surviving tumour cells in surgical resection specimens. They were followed up for a minimum of 2.5 years. Factors significantly associated with poor overall survival were a high serum level of alkaline phosphatase at diagnosis and tumour cells expressing M...

Methane is widespread in the Universe, and its occurrence intimately connected with that of water, often as clathrate hydrate, likely priority form which methane stored icy moons, water-rich exoplanets but also depths Earth’s oceans. Arrangement stability range crystalline structures, decomposition conditions, miscibility resulting dense fluid mixtures are crucial for modeling static dynamic pr...

The theoretical and practical aspects of polymer-polymer miscibility in the solid amorphous state are reviewed. The polymers include homopolymers and both random and block copolymers. Although present theoretical treatments of polymer-polymer miscibility all contain the random mixing hypothesis and are thus not applicable to mixtures that involve specific interactions between the components, mo...

A promising method for transforming lignin derivatives into high-value chemicals and biofuels is hydrodeoxygenation (HDO), which anticipated to be a viable feasible protocol the biorefinery. Nonetheless, requirements of high temperature H2 pressure are two main hurdles in HDO process. Herein, we developed highly active Pd-decorated Bi2MoO6 nanoflakes complete selective vanillin (a typical ligni...

BACKGROUND Matrix metalloproteinase (MMP) and cardiac inhibitor of metalloproteinase (CIMP) are coexpressed in the heart. Although it is known that oxidative stress activates MMP and CIMP inhibits MMP, it is unclear whether CIMP administration attenuates oxidative stress and MMP-mediated cardiac dilatation. METHODS AND RESULTS Arteriovenous fistula (AVF) was created in C57BL/J6 mice, and CIMP...

I consider the effect of a small concentration of a molecule, such as a short-chain alcohol, on the miscibility transition temperature of a giant plasma membrane vesicle. For concentrations sufficiently small such that the system can be treated as a dilute solution, the change in transition temperature is known to depend upon the extent of the molecule's partition into the coexisting liquid-dis...
