Identification of HPV DNA in patients with juvenile-onset recurrent respiratory papillomatosis using SYBR Green real-time PCR.

Objective: Recurrent respiratory papillomatosis (RRP) is the most common benign neoplasm affecting the larynx and upper respiratory tract in children. Human papillomavirus (HPV) has been implicated as the cause of RRP, most commonly types 6 and 11. The present study was undertaken to evaluate the occurrence of HPV types in a group of patients with juvenile-onset RRP (JORRP).

Significance of M-cells in the panautoprotection of the body.

Life consists of continuous acceptance, adequate processing and appropriate use of energy-carriers present in and around the body, along with effective elimination of those of them which invade the organism from outside, or appear inside, thus threatening its existence. It is clear that all cells making up the organism are naturally involved in its protection. Since no "extracorporal bodyguards" have been detected so far, recently I introduced the concept of panautoprotection in the human organism, which was subsequently expanded to comprise perhaps the broadest and most sufficiently exhausting paradigm on the essence of life and other known events in the Universe.

Surfactant-producing epithelium in the dorsal part of the cartilaginous eustachian tube of mice. Light, transmission, and scanning electron microscopic observations.

The nonciliated area in cartilaginous roof tubothelium of 14 conventional mice was examined histologically and classified as a modified transitional respiratory epithelium. On the free cell surface numerous short microvilli were found. On the lower roof surface in the midcartilaginous portion and especially near the pharyngeal orifice, a convoluted pattern of ridges and pits was observed.
