Degenerative alterations of two different glutaraldehyde (GA)-fixed bioprosthetic heart valve materials were investigated in subcutaneous rat implants: Bovine pericardium, prepared according to clinically used bioprosthetic heart valve material (BHV) was compared to alternatively preserved
L-Glutamic acid was shown to increase the stability of cells of the HL-60 line of human promyelocyte leukemia to the cytotoxic action of tumor necrosis factor alpha (TNF-alpha) due to the inhibition of apoptotic and NF-kappaB-activating cascades induced by this cytokine. At the same time, L-glutamic
Gelation and tissue adhesion of mixtures of gelatin and poly (L-glutamic acid) (PLGA) aqueous solution were investigated in the presence of additives following the addition of a water-soluble carbodiimide (WSC) that induced chemical cross linking between gelatin and PLGA. To prevent spontaneous
Alpha-melanocyte stimulating hormone (α-MSH) is involved in normal skin wound healing and also has anti-inflammatory properties. The association of α-MSH to polyelectrolyte layers with various supports has been shown to improve these anti-inflammatory properties. This study aimed to evaluate the
A novel hyaluronan (HA) derivative, poly(L-glutamic acid)-grafted hyaluronan (PGA-g-HA), was synthesized to improve the durability of conventional HA products for intra-articular injection. The purpose of this study was to investigate the characteristics of the novel HA derivative in terms of
Environmentally responsive hydrogels show enormous potential in various applications, such as tissue engineering and drug delivery. The site-specific controlled drug delivery of hydrogels can improve the therapeutic outcome and minimize the negative side effects. In this work, enzymatically
Polyelectrolyte multilayer films made of poly (L-lysine) (PLL) and poly (L-glutamic acid) (PGA) have been functionalized by covalent binding of a synthetic analogue of the anti-inflammatory peptide, alpha-melanocyte-stimulating hormone (alpha-MSH) to PGA to create biologically active coatings for
Basic and clinical studies have reported rapid and long-lasting antidepressant effects of ketamine. Although previous studies have proposed several mechanisms underlying the antidepressant effects of ketamine, these mechanisms have not been completely In this study, target compounds 5-12 were synthesized via acid amine coupling of ibuprofen and naproxen with methyl ester derivatives of amino acids, namely, l-proline, sarcosine, l-tyrosine, and l-glutamic acid. When tested for anti-inflammatory activity using the acute carrageenan-induced hind paw
This study describes the potentiality of hydrogels composed of gelatin and poly(L-glutamic acid) (PLGA) as a biological glue for soft tissues and compares its effectiveness with that of a conventional fibrin glue. Water-soluble carbodiimides (WSC) were used to crosslink the aqueous mixture of
Possible central modulation of acute peripheral inflammation by putative amino acid neurotransmitters was investigated in rats by adopting formalin induced pedal inflammation as an experimental model. Out of five amino acids (GABA, glycine, DL-alanine, L-glutamic acid and L-aspartic acid) tested,
The analogous β-carboline alkaloids, harmaline (HAL) and harmine (HAR), possess a variety of biological properties, including acetylcholinesterase (AChE) inhibitory activity, antioxidant, anti-inflammatory, and many others, and have great potential for treating Alzheimer's disease (AD). However,
Two rare N-β-D-glucopyranosyl-1H-indole-3-acetic acid conjugates, N-[2-(1-β-D-glucopyranosyl)-1H-indol-3-yl)acetyl]-L-glutamic acid (1) and N-[2-(1-β-D-glucopyranosyl)-1H-indol-3-yl)acetyl]-L-aspartic acid (2) were isolated from Ginkgo biloba. The structures were elucidated by analyses of HRMS and
L-Glutamic acid acts as the major excitatory neurotransmitter and, at the same time, represents a potential neurotoxin for the mammalian central nervous system (CNS). The termination of excitatory transmission and the maintenance of physiologic levels of extracellular glutamate, which is necessary
Lower levels of tryptophan (TRP) have been identified in people with inflammatory bowel disease and in dogs with protein-losing enteropathy (PLE). No data on serum amino acids (AAs) but some on plasma in canine immunosuppressant-responsive enteropathy (IRE) are available. The aim of
