Synergistic Effects of Photo-Irradiation and Curcumin-Chitosan/Alginate Nanoparticles on Tumor Necrosis Factor-Alpha-Induced Psoriasis-Like Proliferation of Keratinocytes.

Only registered users can translate articles

Psoriasis is a chronic inflammatory skin disease characterized by hyperproliferation of the epidermal cells and is clinically presented as thick, bright red to pink plaques with a silvery scale. Photodynamic therapy (PDT) using visible light has become of increasing interest in the treatment of

Extracorporeal shockwave therapy combined with alginate dressing for treatment of sacroiliac decubital necrosis in older adults: A case report.

Only registered users can translate articles

Pressure sores are major clinical problems with limited treatment options.A 62-year-old man, admitted with unresponsive, indifferent mood, and malnutrition. A noval-shaped skin lesion deeping into the fascia was found in the sacrococcygeal

Oral DNA vaccines based on CS-TPP nanoparticles and alginate microparticles confer high protection against infectious pancreatic necrosis virus (IPNV) infection in trout.

Only registered users can translate articles

Infectious pancreatic necrosis virus (IPNV) is the etiological agent of a contagious viral disease causing remarkable mortalities in different fish species. Despite the availability of commercial vaccines against IPN, the disease still constitutes one of the main threats to the aquaculture industry

An oral DNA vaccine against infectious haematopoietic necrosis virus (IHNV) encapsulated in alginate microspheres induces dose-dependent immune responses and significant protection in rainbow trout (Oncorrhynchus mykiss).

Only registered users can translate articles

Administered by intramuscular injection, a DNA vaccine (pIRF1A-G) containing the promoter regions upstream of the rainbow trout interferon regulatory factor 1A gene (IRF1A) driven the expression of the infectious hematopoietic necrosis virus (IHNV) glycoprotein (G) elicited protective immune

Effectiveness of synovial fluid mesenchymal stem cells embedded in alginate beads for treatment of steroid-induced avascular necrosis of the femoral head.

Only registered users can translate articles

OBJECTIVE Treatment of early stage avascular necrosis of the femoral head (AVNFH) is still challenging for clinicians today. Core decompression with the implantation of mesenchymal stem cells (MSCs) has become popular and been proven to be an effective therapy for ANNFH. Synovial fluid MSCs, which

Alginates from wound dressings activate human macrophages to secrete tumour necrosis factor-alpha.

Only registered users can translate articles

Alginates are used to manufacture a number of wound dressings. Clinical observations indicate that they may initiate or accelerate healing of chronic wounds after treatment of underlying pathology. Wound granulation tissue contains large numbers of macrophages and they are thought to regulate the

[A new approach to the pathogenesis of acute tubular necrosis: with special reference to tubular damages caused by coincidental administration of aminoglucoside antibiotics and sodium alginate].

Tumour necrosis factor, but not interferon-gamma, is essential for acquired resistance to Listeria monocytogenes during a secondary infection in mice.

Only registered users can translate articles

Mice with a secondary Listeria monocytogenes infection eliminate the bacteria much faster and more efficiently from their organs than mice with a primary infection. During the course of a secondary infection, serum concentrations of interferon-gamma (IFN-gamma) and tumour necrosis factor-alpha (TNF)

Local, Controlled Release In Vivo of Vascular Endothelial Growth Factor Within a Subcutaneous Scaffolded Islet Implant Reduces Early Islet Necrosis and Improves Performance of the Graft.

Only registered users can translate articles

Islet transplantation remains the only alternative to daily insulin therapy for control of type 1 diabetes (T1D) in humans. To avoid the drawbacks of intrahepatic islet transplantation, we are developing a scaffolded islet implant to transplant islets into nonhepatic sites. The implant test bed,

Biological activities of alginate.

Only registered users can translate articles

To gain insight into the structure-activity relationship of alginate, we examined the effect of alginates with varying molecular weights and M/G ratio on murine macrophage cell line, RAW264.7 cells in terms of induction of tumor necrosis factor-α (TNF-α) secretion. Among the alginates tested,

Biodegradable intramedullary nails reinforced with carbon and alginate fibers: in vitro and in vivo biocompatibility.

Only registered users can translate articles

BACKGROUND Commonly, intramedullary nails are made of nondegradable materials, and hence they need to be removed once the bone fracture is healed. We propose a novel composite material consisting of poly-L-lactide matrix modified with carbon and alginate fibers to be used for biodegradable

Hematoma-inspired alginate/platelet releasate/CaPO4 composite: initiation of the inflammatory-mediated response associated with fracture repair in vitro and ex vivo injection delivery.

Only registered users can translate articles

A clinical need continues for consistent bone remodeling within problematic sites such as those of fracture nonunion, avascular necrosis, or irregular bone formations. In attempt to address such needs, a biomaterial system is proposed to induce early inflammatory responses after implantation and to

Effect of alginate-chitosan sustained release microcapsules for transhepatic arterial embolization in VX2 rabbit liver cancer model.

Only registered users can translate articles

Two lipid-solid dispersion loading Norcantharidin sustained-released microspheres of alginate-chitosan (NCTD/LSD-ACMs) were prepared via the emulsification-gelation method. The effects of microspheres for transarterial hepatic chemoembolization were evaluated in VX2 rabbit liver cancer model. The

Three-dimensional plotted alginate fibers embedded with diclofenac and bone cells coated with chitosan for bone regeneration during inflammation.

Only registered users can translate articles

Alginate hydrogel fibers embedded with bone cells and diclofenac were coated with a layer of chitosan hydrogel and made into a porous scaffold by three-dimensional (3D) printing for drug release and bone regeneration. It was hypothesized that the chitosan coating could improve the scaffold's drug

Xenotransplantation of parathyroids in rats using barium-alginate and polyacrylic acid multilayer microcapsules.

Only registered users can translate articles

The integrity and function of encapsulated parathyroid tissue following xenotransplantation is limited by oxygen and nutrition supply and capsule fibrosis. Since some of these factors depend on stability and biocompatibility of the coating material, multilayer microcapsules have been developed.
