BACKGROUND
Boron nitride nanotubes (BNNTs) represent a new opportunity for drug delivery and clinical therapy. The present work has the objective to investigate pectin-coated BNNTs (P-BNNTs) for their biocompatibility on macrophage cultures, since these cells are among the first components of the
Flour made from Passiflora edulis fruit peel has been used in Brazil to treat diabetes. This study evaluated the effects of pectin from P. edulis on rats with alloxan-induced diabetes, on myeloperoxidase release from human neutrophils, and on carrageenan-induced paw edema. In the experiments on
Injectable hydrogels with conductivity are highly desirable as scaffolds for the engineering of various electrical stimuli-responsive tissues, including nerve, muscle, retina, and bone. However, oxygen deprivation within scaffolds can lead to failure by causing cell necrosis. Therefore, an oxygen
BACKGROUND
Novel pectin-honey hydrogels have been developed and characterized as medical device. Ideally, a wound dressing should maintain optimal fluid affinity, permit moisture evaporation, protect the wound from microbes, and have shape-conformability, biocompatibility, and antibacterial
In situ gellable hydrogels are more attractive in many biomedical and biopharmaceutical applications than pre-formed hydrogels because they can be implanted simply by injection and allow homogeneous incorporation of bioactive materials. In this study, the potential suitability of in situ gellable
BACKGROUND
Cardiovascular complications are among the leading causes of morbidity and mortality in diabetes mellitus. Despite the beneficial effects of subcutaneous insulin, reports suggest that the therapy itself precipitates cardiovascular risks due to the high insulin concentration administered.
Peripheral neuropathic condition is amongst the classical symptoms of progressed diabetes. An intensive glycemic control with insulin injections has been shown to delay the onset and the progression of this condition in diabetes. In this study, we investigated the effect of pectin-insulin patch
Riboflavin (Rf) is an endogenous photosensitizer, which can participate in Type I and Type II processes. We have recently shown that the yield of the triplet excited states of Rf is enhanced in the presence of pectin-coated silver nanoparticles (Pec@AgNP) due to formation of a complex between Rf and
The effect of a pectin-supplemented enteral diet on experimental colitis was compared with parenteral nutrition and with a pectin-free enteral diet. Forty-five rats had feeding catheters placed into either the stomach (IG, n = 31) or the superior vena cava (IV, n = 14) and then received acetic acid
Inflammation is a normal physiological process; however, dysregulation of this process may contribute to inflammatory-based chronic disorders and diseases in animals and humans. Therefore, the antioxidant and anti-inflammatory properties of natural products, often recognized in traditional medicine
Superficial scald is a physiological disorder of apple fruit characterized by sunken, necrotic lesions appearing after prolonged cold storage, although initial injury occurs much earlier in the storage period. To determine the degree to which the transition to cell death is an active process and
Number of various natural polymer-based drug delivery systems targeting the colon is reported for different applications. Most of the research is based on the class of natural polymers such as polysaccharides. This study compares the anti-inflammatory effect of different polysaccharide The effect of various antimicrobial agents, such as aureomycin, terramycin, streptomycin, chloromycetin, penicillin, polymyxin, and sulfaguanidine on the development of massive dietary necrosis of the liver in rats has been studied. Delay in the production of hepatic necrosis was obtained from
Dickeya dadantii is a broad host range phytopathogenic bacterium provoking soft rot disease on many plants including Arabidopsis. We showed that, after D. dadantii infection, the expression of the Arabidopsis BOS1 gene was specifically induced by the production of the bacterial PelB/C pectinases
CONCLUSIONS
Pectin is a structural polysaccharide that is integral for the stability of plant cell walls. During soft rot infection, secreted virulence factors from pectinolytic bacteria such as Erwinia spp. degrade pectin, resulting in characteristic plant cell necrosis and tissue maceration.
