Abstract This paper presents a proposal to source-filter theory of voice production, more precisely related voiced sounds. It is model generate signal using linear and time-invariant systems takes into account the phonation biophysics cyclostationary characteristics signal, vibrational behavior vocal cords. The suggests that oscillation frequency cords function its mass length, but controlled b...

Using a fibreoptic laryngoscope, we have recorded on video tape the movements of the vocal cords after induction of anaesthesia with either propofol or thiopentone. The angle formed by the vocal cords decreased after induction of anaesthesia in both groups. This reduction in angle was significantly greater in the thiopentone group. The vocal cords closed completely in four patients in the thiop...

The aggregation of mycobacterial cells in a definite order, forming microscopic structures that resemble cords, is known as cord formation, or cording, and is considered a virulence factor in the Mycobacterium tuberculosis complex and the species Mycobacterium marinum. In the 1950s, cording was related to a trehalose dimycolate lipid that, consequently, was named the cord factor. However, moder...

To the Editor: We would like to report the use of fibreoptic endoscopy as a method for evaluating vocal cord function following surgical procedures that could injure their innervation. A 45-yr-old woman underwent resection of the thyroid isthmus and right thyroid lobectomy. Anaesthesia and surgery were uneventful but the surgeon requested that vocal cord function be evaluated laryngoscopically ...

BACKGROUND AND OBJECTIVES The brachial plexus represents an important network of nerves, commonly approached in nerve blocks prior to surgical procedures. Therefore, the knowledge of its anatomy is indispensable so those procedures can be carried out accordingly. The objective of the present study was to analyze the morphology of brachial plexus cords with special emphasis to its topographic re...

Tissue vascularization and integration with host circulation remains a key barrier to the translation of engineered tissues into clinically relevant therapies. Here, we used a microtissue molding approach to demonstrate that constructs containing highly aligned "cords" of endothelial cells triggered the formation of new capillaries along the length of the patterned cords. These vessels became p...

Introduction: Reinke’s edema, also known as polypoid degeneration of vocal cords, is a bilateral, symmetrical swelling the whole membranous part cords. Surgery has been mainstay treatment for edema. Thus, patients are often left with practically no non-invasive option. Case Summary: This case 40-year-old male, teacher, who presented hoarseness voice 1 year and opted homeopathic when he was advi...
