Effects of Large Pressure Amplitude Low Frequency Noise in the Parotid Gland Pe...
Introduction: In tissues and organs exposed to large pressure amplitude low frequency noise fibrosis occurs in the absence of inflammatory signs, which is thought to be a protective response. In the parotid gland the perivasculo-ductal connective tissue surrounds arteries, veins and the ductal tree. Perivasculo-ductal connective tissue is believed to function as a mechanical stabilizer of the glandular tissue.M...
Effects of low-frequency noise on cardiac collagen and cardiomyocyte ultrastruc...
Antunes, Eduardo; Borrecho, Gonçalo; Oliveira, Pedro; Matos, António P. Alves de; Brito, José; Águas, Artur; Martins dos Santos, José"Introduction: Low-frequency noise (LFN) leads to the development of tissue fibrosis. We previously reported the development of myocardial and perivascular fibrosis and a reduction of cardiac connexin43 in rats, but data is lacking concerning the affected type of collagen as well as the ultrastructural myocardial modifications. Objectives: The aim of this study was to quantify cardiac collagens I and III and to...
Immunohistochemical evaluation of cardiac connexin43 in rats exposed to low-fre...
Antunes, Eduardo; Borrecho, Gonçalo; Oliveira, Pedro; Brito, José; Águas, Artur; Martins dos Santos, José"Introduction: Low-frequency noise (LFN) leads to an abnormal proliferation of collagen and development of tissue fibrosis. It has been shown that myocardial fibrosis in association with gap junction remodeling occurs in several cardiac diseases and can be implicated in the development of ventricular tachyarrhythmias. We previously reported a strong development of myocardial fibrosis induced by LFN in rats but ...
