rupture/tyrosine

BACKGROUND Subarachnoid hemorrhage caused by a ruptured intracranial aneurysm (RIA) is a devastating condition with significant morbidity and mortality. Despite the fact that RIAs can be prevented by microsurgical clipping or endovascular coiling, there are no reliable means of effectively

The photofragmentation pathways at 263 nm of several small peptides containing tyrosine as the UV chromophore have been characterized using a multi-coincidence technique. A detailed study of the fragmentation dynamics of protonated Glycine-Tyrosine (GYH(+)), Tyrosine-Glycine (YGH(+)),

Incorporation of tyrosine within synthetic macromolecules via the controlled radical polymerization technique is of particular interest due to the presence of a phenolic group in tyrosine imparting high inhibition potential. Tyrosine incorporation is also fascinating from a medicinal point of view

OBJECTIVE Neurotrophins prevent the death of neurons during embryonal development and have potential as therapeutic agents. During development, neuronal death occurs only by apoptosis and not by necrosis. Following injury, however, neurons can die by both processes. Data from prior studies have not

Vulnerable or high-risk atherosclerotic plaques often exhibit large lipid cores and thin fibrous caps that can lead to deadly vascular events when they rupture. In this study, polyethylene glycol (PEG)-micelles that incorporate a gadolinium diethylenetriamine pentaacetic acid (Gd-DTPA) amphiphile

OBJECTIVE To evaluate diagnostic accuracy studies for rupture of the fetal membranes (ROM). RESULTS Sample sizes of recent studies are small and studies used different 'silver standard' definitions for ROM. Therefore, reported results should be interpreted with caution. Over the review period the

Ovarian development and mature ovarian function are subjected to the regulatory influence of several growth factors exerting their biologic actions via membrane-anchored receptors endowed with intrinsic tyrosine kinase activity. The actions of these growth factors appear to be anatomically,

The balance between matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) regulates extracellular matrix turn-over in normal animal development, cancer cell metastasis, atherosclerotic plaque rupture and erosion of arthritic cartilage. Transforming growth factor beta

BACKGROUND There is increasing evidence suggesting that development of progressive canine cranial cruciate ligament (CCL) rupture involves a gradual degeneration of the CCL itself, initiated by a combination of factors, ranging from mechanical to biochemical. To date, knowledge is lacking to what

We present herein a short tripeptide sequence (Lys-Phe-Gly or KFG) that is situated in the juxtamembrane region of the tyrosine kinase nerve growth factor (Trk NGF) receptors. KFG self-assembles in water and shows a reversible and concentration-dependent switching of nanostructures from nanospheres

Tyrosine D (TyrD), a side path electron carrier of photosystem II (PS II), has been studied by light-induced Fourier transform infrared (FTIR) difference spectroscopy in PS II core complexes of Synechocystis sp. PCC 6803 using the experimental conditions previously optimized to generate the pure

Matrix metalloproteinase-2 (MMP-2, gelatinase A) and thrombin contribute to many long-term (patho)physiological processes requiring the proteolytic breakdown of the vascular extracellular matrix (e.g., normal tissue repair, remodeling, tumor invasion, atherosclerosis plaque rupture). Thrombin (10 to

Elastin is an abundant extracellular matrix protein in elastic tissues, including the lungs, skin and arteries, and comprises 30-57% of the aorta by dry mass. The monomeric precursor, tropoelastin (TE), undergoes complex processing during elastogenesis to form mature elastic fibres. Peroxynitrous
