In order to gain insight into the biological significance of a collagenase inhibitor secreted by human skin fibroblasts, we examined various human connective tissues and body fluids for such a protein. The inhibitors found in these tissues were compared immunologically to skin fibroblast inhibitor by Ouchterlony analysis and by the development of a highly specific enzyme-linked immunosorbent as...

Background: Camellia sinensis and Zataria multiflora as the potent antioxidants and anti-inflammations are crucial in the management of wound therapy. Lipopolysaccharide (LPS) was used for the proliferative potential on fibroblast cells and induction of inflammatory mediators. Objective: We examined the effects of LPS and herbal extracts combination in order to identify their mechanisms of a...

Monoclonal antibodies were generated to antigens on human foreskin keratinocytes to identify epithelial-specific molecules. Spleen cells from BALB/c mice, immunized with membrane preparations from primary explants of foreskin epithelial cells, were fused with the NS-1 mouse myeloma line. Hybridoma supernatants were screened for the desired immunological reactivity using enzyme-linked immunosorb...

In this study, an attempt has been made to synthesize nanoemulsions using Trachyspermum ammi tincture. The nanoemulsion specifications are characterized by TEM, DLS, and zeta potential. anti-tumour cell toxicity effects of the biosynthesized evaluated chorioallantoic membrane (CAM) MTT assays, respectively. For CAM test, length number blood vessels around gelatine sponge. According DLS analysis...

Acute lung injury involving extremely immature lungs often heals without excessive fibrosis unlike later in gestation and in adults. Several factors may be involved, but fibroblast contraction of collagen has been linked to the level of wound fibrosis. To assess whether human lung fibroblasts of fetal versus adult origin differ in ability to contract collagen and define the molecular underpinni...

The plant alkaloids vinblastine and colchicine are known to arrest cells in mitosis by virtue of their binding to spindle protein. These drugs are also capable of binding to microtubule protein and causing these structures to disaggregate into nonfunctional subunits (1, 2). Microtubular structures are thought to be involved in the secretory process of a number of proteins including insulin (7),...

introduction: this study aimed to compare the cytotoxicity of mta fillapex, ah-26 and apatite root canal sealers at different times after mixing. methods and materials: in this in vitro study, mta fillapex, ah-26 and apatite root canal sealer were spilled uniformly by 40 µm mesh in a 96-well plate. then, human fetal foreskin fibroblast cell line (hfff2) were added to each sealer cell culture me...

The current study examined the genotoxic effect of biosynthetic zinc oxide nanoparticles ZnONPs using Vitex agnus-castus plant, which contains effective compounds that inhibit growth pure cancer cells. phenotypic and structural characteristics biosynthesized were detected scanning electron microscopy (SEM). Most dense spherical with sizes ranging from (20-61) nanometers, on cervical cell line H...
