The forced oscillation technique (FOT) is a useful tool to assess respiratory resistance and reactance during tidal breathing in patients with respiratory diseases, specifically asthma and chronic obstructive pulmonary disease. Although the FOT has been clinically used, results of respiratory impedance can be affected by various factors such as upper airway artifact. We investigated the effects...

There can be several factors that are likely to have played a role in the evolution of hand preference in humans and non-human primates, which the existing theories do not consider. There exists a possibility that hand preference in non-human primates evolved from the pre-existing lateralities in more elementary brain functions and behavior, or alternatively, the two coevolved. A basic example ...

BACKGROUND The tear trough and the lid/cheek junction become more visible with age. These landmarks are adjacent, forming in some patients a continuous indentation or groove below the infraorbital rim. Numerous, often conflicting procedures have been described to improve the appearance of the region. The purpose of this study was to evaluate the anatomy underlying the tear trough and the lid/ch...

Meningoencephalitis caused by Cryptococcus neoformans (Cn) has become one of the leading causes of mortality in AIDS patients. Understanding the interactions between Cn and phagocytes is fundamental in exploring the pathogenicity of cryptococcal meningoencephalitis. Cn may be extracellular or contained in the monocytes, macrophages, neutrophils, dendritic cells and even endothelial cells. The i...

BACKGROUND The cheek rotation flap has sufficient blood flow and large flap size and it is also flexible and easy to manipulate. It has been used for reconstruction of defects on cheek, lower eyelid, or medial and lateral canthus. For the large defects on central nose, paramedian forehead flap has been used, but patients were reluctant despite the remaining same skin tone on damaged area becaus...

Cheek-marking in yellow-bellied marmots (Marmota flaviventris) was studied by observations of cheek-marking in two colonies from 10 June to 6 August, 1996 and by experimental studies of responses to olfactory secretions from the perioral gland. The rate of cheek-marking declined significantly as the season progressed. Most cheek-marking occurred within 3 m of the main burrow system and was prim...

OBJECTIVES Oral submucous fibrosis (OSMF) is a potentially malignant disorder of oral cavity, pharynx and upper digestive tract, characterized by progressive inability to open the mouth. Based on clinical and/or histopathological features, various classifications and grading systems have been put forth till date. The aim of the present study was to study the variance in cheek flexibility in OSM...

This study presents the results of T. mentagrophytes inoculation in the cheek pouch of the hamster, an immunologically privileged site. Forty two animals were used: 21 inoculated with 10(6) fungi in the cheek pouch (group 1) and 21 inoculated initially with 10(6) fungi in the foot pad and 15 days later in the cheek pouch, with the same amount of fungi (group 2). Animals were sacrificed at 20 ho...

Dear Sir, Cheek rotation flaps1-3 are used to reconstruct lower eyelids. After rotating the flap, the suture line on the cheek is not aligned with a relaxed skin tension line, and postoperative scars that intersect the margin of the lower eyelid at angles close to 90 ̊ may cause downward contractures of the lower eyelid. We describe herein 2 cases in which we avoided this problem by using w-plas...
