Connective Tissue Activation
نویسنده
چکیده
A polypeptide which induces hypermetabolism in normal synovial fibroblasts in tissue culture is described. The metabolic changes induced included a marked increase in hyaluronate formation, lactate formation and glucose uptake; formation of soluble and fibrous collagen was depressed. An assay method is presented which permits quantitative comparisons of samples for connective tissue activating peptide (CTAP) activity. The CTAP appeared to be widely distributed in human tissues, the amount of activity being a function of cell density. A role for CTAP in rheumatoid inflammation is proposed.

Normal Pressure hydrocephalus (NPH) is characterized by gait apraxia, urinary incontinence, and dementia. Mixed connective tissue disease (MCTD) is an autoimmune connective tissue disease that has never been reported to cause NPH. Our patient was a 67-year man with a one-year history of gradual worsening gait and balance, urinary urgency with urge incontinence and decreased short-term memory. P...
متن کاملA Bilateral Pediculated Palatal Periosteal Connective Tissue Flap for Coverage of Large Bone Grafts in the Anterior Maxillary Region
Introduction: Coverage of bone grafts is very important in reconstructive surgery. In edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. Here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for up...

The B cell is a vital contributor to humoral immunity. The B cell-specific antigen CD20 is expressed during B cell development, starting at the pre-B cell level and persists through B cell differentiation, but is lost during terminal differentiation to plasma cells. Rituximab is a monoclonal antibody that destroys both normal and malignant B cells that have CD20 on their surfaces and is ther...

Background and Aim: Several surgical approaches have been used to achieve root coverage. The Subepithelial Connective Tissue Graft (SCTG) procedure has been shown to be a predictable means to treat gingival recession. Semilunar Coronally Positioned Flap (SCPF) is a simple mucogingival surgery to cover the exposed root surface without harvesting the palatal connective tissue. The purpose of this...
