BACKGROUND Chronic hypertension may cause left ventricular (LV) remodeling, alterations in cardiac function, and the development of chronic heart failure (CHF). Changes in the composition of the extracellular matrix (ECM) known to occur in hypertension are believed to be causally related to these structural, functional, and clinical outcomes. However, whether the determinants of ECM composition...

Matrix metalloproteinases (MMPs) are known to degrade components of the extracellular matrix. More recently, in myocardial oxidative stress injury including ischemia-reperfusion, MMP-2 is activated and degrades troponin I and α-actinin. MMP activity is regulated at several levels. We recently showed that MMP-2 is localized in the caveolae of cardiomyocytes and is negatively regulated by caveoli...

The viscosity behavior of aqueous mixtures formed by a polyelectrolyte (A) and a neutral polymer (B), such as chitosan/poly(vinyl alcohol) (Ch/PVA) and microcrystalline chitosan/poly(vinyl alcohol) (MCCh/PVA), have been investigated at 25 °C. The intrinsic viscosity and the viscosity interaction parameter of each polymer in 0.1 mol·dm-3 CH3COOH/0.2 mol·dm-3 NaCl solution as well as the ternary ...

In this paper, we report the calculated phase diagrams of V-Nb, V-Ta, and Nb-Ta alloys computed by combining the total energies of 40–50 configurations for each system (obtained using density functional theory) with the cluster expansion and Monte Carlo techniques. For V-Nb alloys, the phase diagram computed with conventional cluster expansion shows a miscibility gap with consolute temperature ...

A series of carboxylate compounds were prepared from N(alpha)-substituted 2,3-diaminopropionic acid and were tested for efficacy as matrix metalloproteinase (MMP) inhibitors. During modeling of the initial compound 10a, we utilized three-dimensional structure modeling software (InsightII/Discover Ver. 2.98). Some of the prepared carboxylate derivatives, such as carbamate compounds (12c,d, 22) a...

PURPOSE Matrix metalloproteinase (MMP)-mediated turnover of extracellular matrix (ECM) affects outflow resistance in the uveoscleral pathway. The balance of MMPs and tissue inhibitors of metalloproteinases (TIMPs) governs the rate of ECM turnover in many tissues. The hypothesis was that a differential effect on MMPs and TIMPs in ciliary body smooth muscle (CBSM) cells would relate to the relati...
