OBJECTIVE To investigate whether functional endoscopic sinus surgery (FESS) for the treatment of chronic rhinosinusitis will induce changes in intraocular pressure (IOP). DESIGN Prospective, nonrandomized, preoperative and postoperative study. SETTING University-affiliated medical center. PATIENTS Thirty patients who underwent FESS for chronic rhinosinusitis with or without polyps were pr...

The Micro-Grid (MG) stability is a significant issue that must be maintained in all operational modes. Usually, two control strategies can be applied to MG; V/f control and PQ control strategies. MGs with V/f control strategy should have some Distributed Generators (DGs) which have fast responses versus load changes. The Flywheel Energy Storage System (FESS) has this characteristic. The FESS, w...

BACKGROUND Using the reverse Trendelenburg position (RTP) during functional endoscopic sinus surgery (FESS) is a safe, simple, and cost-free method that has been found to reduce intraoperative blood loss. However, the critical angle of RTP that produces the least amount of bleeding without compromising surgical technique and safety remains unanswered. The objective of this study was to assess t...

BACKGROUND Nasal polyposis is a disease known to be associated with asthma. The management is anti-inflammatory, with topical and oral corticosteroids as the first-line treatment. The effect of surgical treatment on lower airway inflammation has not been sufficiently studied. AIM The aim of this study is to investigate the effects of functional endoscopic sinus surgery (FESS) as well as fluti...

OBJECTIVES/HYPOTHESIS To provide the final results from the REMODEL (randomized evaluation of maxillary antrostomy versus ostial dilation efficacy through long-term follow-up) full-study cohorts and perform meta-analyses of standalone balloon sinus dilation studies to explore long-term outcomes in a large patient sample. STUDY DESIGN Randomized controlled trial and meta-analysis. METHODS Fi...

Usage of flywheel energy storage system (FESS) is a common method for frequency regulation due to its high power injection capacity and long life time. FESS is equipped by two back-to-back inverters including grid-side inverter and machine-side inverter. In conventional method, the machine-side inverter sets the active power and machine flux while grid-side inverter sets the reactive power and ...

BACKGROUND Nasal and paranasal cavities are supposed to contribute substantially to the vocal tract resonator properties. However, their acoustical effects as well as the effects of sinus surgery on the voice remain unclear. In this work we investigate resonance phenomena of paranasal sinuses prior to and after various rhinosurgical procedures in cadaveric human sinonasal tracts and correspondi...

This paper forms a Virtual Energy Storage System (VESS) and validates that VESS is a cost-effective way to provide the function of energy storage through the utilization of the present network assets represented by flexible demand. As a solution to convert to low carbon cities, a VESS is firstly modelled to store and release energy in response to regulation signals by coordinating the demand re...

The increase in steady-state force after active lengthening in skeletal muscle, termed force enhancement (FE), has been observed for nearly one century. Although demonstrated experimentally at various structural levels, the underlying mechanism(s) remain unknown. We recently showed that the Drosophila jump muscle is an ideal model for investigating mechanisms behind muscle physiological propert...

We conducted a retrospective study to determine the prevalence of Samter's triad (nasal polyps, asthma, and aspirin sensitivity) in 208 consecutively presenting patients who had undergone functional endoscopic sinus surgery (FESS) for chronic rhinosinusitis from September 2001 through August 2003. Overall, Samter's triad was found in 10 patients (4.8%); subgroup analyses showed that the prevale...
