Comparison of clinical outcomes using a Piezosurgery device vs. a conventional osteotome for lateral osteotomy in rhinoplasty.

Our aim for this study was to evaluate and compare the clinical outcomes in patients who underwent lateral osteotomy with a Piezosurgery device or a conventional osteotome in open-technique rhinoplasty. This cohort trial involved 65 patients (36 women and 29 men; average age: 23.6 ± 5.

Comparison of Acoustic and Stroboscopic Findings and Voice Handicap Index between Allergic Rhinitis Patients and Controls.

Background: In our experience Allergic Rhinitis (AR) patients suffer from voice problems more than health subjects.

Aims: To investigate the acoustic analysis of voice, stroscopic findings of larynx and Voice Handicap Index scores in allergic rhinitis patients compared with healthy controls.

Study Design: Case-control study.

Skin problems following septorhinoplasty.

Objectives/hypothesis: Septorhinoplasty is one of the most commonly performed plastic surgery procedures in the world. Studies on septorhinoplasty in the literature mainly focus on the surgical procedures and their outcomes, but the general appearance of the nose and nasal skin following surgery is also very important.

Study Design: Case-control study examining 30 septorhinoplasty patients and 20 septoplasty patients for postoperative skin conditions.

Benign paroxysmal positional vertigo following septorhinoplasty.

We present 2 cases of benign paroxysmal positional vertigo (BPPV) following septorhinoplasty. Benign paroxysmal positional vertigo following septorhinoplasty is an unusual entity. Two young women who had difficulty in breathing and nasal deformity underwent septorhinoplasty.

Ultrasonic monitoring of glycerol settling during transesterification of soybean oil.

A low-intensity ultrasonic measurement system was used to monitor the products of transesterification of soybean oil in methanol to FAME (biodiesel). The byproducts of the transesterification reaction are methyl esters, glycerol and other products. During the transesterification reaction, the glycerol, having a higher density than the methyl ester, settles at the bottom of the reaction vessel.

The early response gene IEX-1 attenuates NF-kappaB activation in 293 cells, a possible counter-regulatory process leading to enhanced cell death.

The early response gene IEX-1 is involved in the regulation of cellular growth and survival, and its expression is related to stress-, growth- and death-inducing signals. Addressing the role of IEX-1 in the promotion of apoptosis, we investigated the effect of IEX-1 on nuclear factor-kappaB (NF-kappaB) activation. Stably transfected HEK-293 cells conditionally overexpressing IEX-1 exhibit decreased levels of NF-kappaB activity, either basal or TNFalpha induced, as shown by gel-shift and luciferase reporter gene assay.
