Introduction: Oral Lichen Planus (OLP) is one of the most common mucocutaneous lesion, and its etiologic factors have not been elucidated yet. OLP has two different clinical forms including reticular and erosive. Mast cells function in non-specific immunology is an etiologic factor involved in the formation of lichen planus. This study aimed at determining the pattern of mast cells presence in ...

Connective tissue growth factor (CCN2), a member of the CCN family of proteins, is a cysteine-rich matricellular protein. Connective tissue growth factor is not normally expressed in dermal fibroblasts unless induced. The most potent inducer of connective tissue growth factor thus far identified is transforming growth factor beta. Connective tissue growth factor, however, is constitutively over...

Hypothesis / aims of study Collagen is ubiquitous in the human body and it is the main component of connective tissue. Several different types of collagen have been identified and is known that it is strongly represented in the vaginal wall and endopelvic fascia. Therefore collagen is the main component of the pelvic supporting structures and Pelvic Organ Prolapse (POP) is the clinical manifest...

We evaluated a polybutylene/polypropylene blend in a blown microfiber configuration in vitro for potential use as the peripheral area of a keratoprosthetic device. Material properties such as ultimate tensile strength and ultimate elongation were measured. Stromal fibroblasts were seeded onto the material in vitro, and cell proliferation between uncoated and Type I collagen coated discs did not...

It is established that cortisone and hydrocortisone may prevent inflammation but their precise mode of action remains unknown. Therefore, it is desirable to examine the histological modifications which these hormones elicit in connective tissue under varied experimental conditions. This investigation has two objectives, the first being to compare the changes which occur in connective tissue sur...

Cardiac hypertrophy was produced in rats by constricting the abdominal aorta subdiaphragmatically. The weight of the left ventricle was significantly elevated 2 days after aortic constriction and was 19% higher than in shamoperated animals at 11 days. The activity of protocollagen proline hydroxylase (PPH), an enzyme participating in collagen biosynthesis, and the hydroxyproline content of the ...

Duchenne’s muscular dystrophy is the most common hereditary neuromuscular disease, which affects all races. Its classical characteristic clinical features being progressive weakness, intellectual impairment and hypertrophy of calves with proliferation connective tissue fibrosis in muscles. As disease inherited as an X-linked recessive trait, thus females not manifesting acting carriers only, se...

In vivo cultivated connective tissue is rich in lipids. That obtained from man and chicken has larger concentrations of neutral fat and cholesterol than connective tissue of other species. Connective tissue synthesizes cholesterol and possesses a striking avidity for retention of either endogenous or exogenous cholesterol. The fibrous portion of sponge-connective tissue of the rabbit incorporat...

Abstract Sahlqvist theory is extended to the fragments of intuitionistic propositional calculus that include conjunction connective. This allows us introduce a character amenable arbitrary protoalgebraic deductive systems. As an application, we obtain theorem for implication connective and extensions linear logic.
