Proline dehydrogenase (PRODH) catalyzes the FAD-dependent oxidation of proline to Δ(1)-pyrroline-5-carboxylate, which is the first step of proline catabolism. Here, we report the structures of proline dehydrogenase from Deinococcus radiodurans in the oxidized state complexed with the proline

Despite the numerous advances made in the prevention and treatment of cardiovascular diseases, there is a need for new strategies to repair and/or regenerate the myocardium after ischemia and infarction in order to prevent maladaptive remodeling and cardiac dysfunction. This article compiles and

Premature rupture of membranes and preterm delivery are associated with Ureaplasma infection. We hypothesized that Ureaplasma induced extracellular collagen fragmentation results in production of the tripeptide PGP (proline-glycine-proline), a neutrophil chemoattractant. PGP release from collagen

Myocardial infarction (MI) in mice results in cardiac rupture at 4-7 days after MI, whereas cardiac fibrosis and dysfunction occur later. N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) has anti-inflammatory, anti-fibrotic, and pro-angiogenic properties. We hypothesized that Ac-SDKP reduces

Our objective was to facilitate ligament tissue reconstruction by characterizing the mechanism of expression of ligament tissue. To accomplish this, we searched for proteins specific to the tissue and introduced them into mesenchymal stem cells. In the two-dimensional phosphorescent gel

The positive ion electrospray ionization (ESI+) mass spectra of peptides usually display only protonated molecules provided that soft ionization conditions are applied (low cone voltage to prevent in-source dissociations). Such ions can be multiply charged depending on the molecular weight of the

The incorporation of proline, a precursor for collagen specific hydroxyproline, is regarded to reflect the metabolism of collagen. In vitro experiments were carried out to investigate the influence of sex steroids on the incorporation of [3H]proline into the human follicular wall. Tissue pieces from

Concentrations of four major solutes (Na(+), K(+), Cl(-), proline) were determined in isolated, intact chloroplasts from the halophyte Mesembryanthemum crystallinum L. following long-term exposure of plants to three levels of NaCl salinity in the rooting medium. Chloroplasts were obtained by gentle

The natural peptide N-Acetyl-Seryl-Aspartyl-Lysyl-Proline (Ac-SDKP) decreases inflammation in chronic diseases such as hypertension and heart failure. However, Ac-SDKP effects on acute inflammatory responses during myocardial infarction (MI) are unknown. During the first 72 hours post-MI,

We have investigated the physical mechanisms through which amino acids influence freeze-thaw damage to isolated spinach (Spinacia oleracea L.) thylakoid membranes. The cryoprotective amino acid proline reduced osmotic membrane rupture during thawing by reducing solute loading of thylakoids during

Glucocorticoid injection is widely used in tendon disorders. Despite previous studies on the histologic and biomechanical changes in tendons after glucocorticoid injections, the role of glucocorticoid in tendon rupture still is controversial. It was hypothesized that glucocorticoid has a direct

Plants frequently experience drought stress. It is well known that silicon (Si) facilitates recovery from drought stress by improving drought resistance in plants. However, the effects of Si on the roots associated with the drought resistance in plants remain elusive. In this study, tomato (cv.

The ovarian surface epithelium (OSE) is known to contribute to postovulatory repair of the ovarian cortex by proliferation and migration over the site of follicular rupture, and by deposition of a basement membrane. We examined the production of other extracellular matrix components in culture by

The purpose was to determine the effects of selected regimens of ultrasound therapy on the rates of repair of injured Achilles tendons of rats. Specific dependent variables examined were tendon breaking strength and rate of collagen formation. A puncture technique was used to induce injuries to both

Atherosclerosis, a progressive disease of medium- and large-sized arteries, constitutes the major cause of death in developed countries, and is becoming increasingly prevalent in developing countries as well. The main consequences of atherosclerosis are myocardial infarction, cerebral infarction and
