Comparison of meat quality, fatty acid composition and aroma volatiles of Chikso and Hanwoo beef.

Asian-Australas J Anim Sci 2018 Sep 25;31(9):1500-1506. Epub 2018 Apr 25.

Department of Applied Animal Science, College of Animal Life Sciences, Kangwon National University, Chuncheon 24341, Korea.

Objective: Although Hanwoo has been selected as the superior commercial beef cattle breed in Korea, Chikso (Korean brindle cattle) is still recognized as a valuable breed for beef production. The aim of this study was to compare the meat quality, fatty acid composition and aroma volatiles of beef from Chikso and Hanwoo steers maintained under identical feed management, as information regarding these characteristics is still limited.

Methods: A total of 19 carcasses with a quality grade of 1 were selected, and strip loin (longissimus lumborum) cuts were collected from 11 Hanwoo carcasses and 8 Chikso carcasses. Read More

Digital Magnifying Glasses for Low-Vision Learners: Bringing Assistive Technologies to the Developing World.

IEEE Pulse 2017 Sep-Oct;8(5):31-35

A student squinting to see the board or holding a textbook inches from his or her nose often provides the first indication of a visual impairment. For most, the cause is a refractive error, readily correctible with eyeglasses. However, for an estimated 40-65 million people globally with functional low vision, the fuzzy words pose a lifelong challenge. Read More

Rhinophyma: Our experience based on a series of 12 cases.

Eur Ann Otorhinolaryngol Head Neck Dis 2018 Feb 21;135(1):17-20. Epub 2017 Sep 21.

Clínica Clarós, C/Los Vergós, 31, CP 08017, Barcelona, Spain.

Introduction: Rhinophyma is a rare, benign and unsightly disease of the skin of the nose that was first described a very long time ago, as illustrated by portrait of an old man with a bulbous nose holding his grandson, by Ghirlandaio in 1490. It was described for the first time by Ferdinando Hebra Von (1816-1880), as the third stage of rosacea. The objective of this study is to report the author's experience and propose a new treatment option in the management of rhinophyma. Read More

Robot-assisted endoscope guidance versus manual endoscope guidance in functional endonasal sinus surgery (FESS).

Acta Otolaryngol 2017 Oct 9;137(10):1090-1095. Epub 2017 Jun 9.

a Department of Otorhinolaryngology, Head and Neck Surgery , University Hospital Bonn , Germany.

Background: Having one hand occupied with the endoscope is the major disadvantage for the surgeon when it comes to functional endoscopic sinus surgery (FESS). Only the other hand is free to use the surgical instruments. Tiredness or frequent instrument changes can thus lead to shaky endoscopic images. Read More

Therapeutic effect of hyaluronic acid in reducing nasal mucosa recovery time after septoplasty.

Ear Nose Throat J 2017 Apr-May;96(4-5):E16-E20

Department of Plastic Surgery, University of Milan, Reconstructive and Aesthetic Plastic Surgery School, MultiMedica Holding S.p.A., Sesto San Giovanni, Milan, Italy.

Mucociliary clearance represents a host defense mechanism of airways that can be compromised by various pathologic conditions, such as nasal septal deviation. Although septoplasty can resolve obstruction, it impairs mucociliary clearance in the immediate postoperative period. Clinical studies have demonstrated how hyaluronic acid can interfere with this function. Read More

[Anesthetic Management of a Patient with Rett Syndrome Presenting Severe Breath Holding and Massive Aerophagia].

Masui 2017 02;66(2):135-138

We anesthetized a patient with Rett syndrome pre- senting intense breath holdings and severe aerophagia for dental treatment The patient had shown an intense breath holding plunging into hypoxia during slow induction with sevoflurane in previous anesthesias. Therefore, we chose rapid sequence induction with intravenous propofol and rocuronium and intubated orally. The length of glottis to tracheal bifurcation was shorter than average patient After a gastric tube was inserted and the content was aspirated, the orotracheal tube was changed to nasotracheal one.

Nasal high flow reduces dead space.

J Appl Physiol (1985) 2017 01 17;122(1):191-197. Epub 2016 Nov 17.

HELIOS Klinik Hagen-Ambrock, Witten-Herdecke University, Hagen, Germany.

Recent studies show that nasal high flow (NHF) therapy can support ventilation in patients with acute or chronic respiratory disorders. Clearance of dead space has been suggested as being the key mechanism of respiratory support with NHF therapy. The hypothesis of this study was that NHF in a dose-dependent manner can clear dead space of the upper airways from expired air and decrease rebreathing. Read More

Eur Arch Otorhinolaryngol 2017 Mar 31;274(3):1455-1462. Epub 2016 Oct 31.

Department of Otorhinolaryngology, Regensburg University Hospital, Franz-Josef-Strauss-Allee 11, 93053, Regensburg, Germany.

The objective is to use anatomical determinations of nasal septum shape and surface area in adults as a design basis for silastic septal splints of universal size and fit and offering maximum possible surface coverage. The objective is also to devise a method of securing the septal splints, so that surface pressure on septal mucosa is distributed as evenly as possible while not interfering with capillary perfusion. Nasal septum area was determined in 21 Caucasian body donors, and nasal septum thickness was measured in 20 CT scans. Read More

Effect of maternal skin-to-skin contact on decolonization of Methicillin-Oxacillin-Resistant Staphylococcus in neonatal intensive care units: a randomized controlled trial.

BMC Pregnancy Childbirth 2015 Mar 19;15:63. Epub 2015 Mar 19.

Departamento de Puericultura e Pediatria (7° andar HCRP), Faculdade de Medicina de Ribeirão Preto - USP, Universidade de São Paulo, Av. Bandeirantes, 3900 - Campus USP, Ribeirão Preto, Brazil.

Background: Decolonization with topical antibiotics is necessary to control outbreaks of multidrug-resistant bacterial infection in the Neonatal Intensive Care Unit (NICU), but can trigger bacterial resistance. The objective of this study was to determine whether skin-to-skin contact of newborns colonized with Methicillin-Oxacillin Resistant Staphylococcus aureus or Methicillin-Oxacillin-Resistant Coagulase-Negative Staphylococcus aureus (MRSA/MRSE) with their mothers could be an effective alternative to promote bacterial decolonization of newborns' nostrils.

Methods: We performed a randomized clinical trial with 102 newborns admitted to the NICU in three hospitals in São Luís, Brazil. Read More

Expiratory flow rate, breath hold and anatomic dead space influence electronic nose ability to detect lung cancer.

BMC Pulm Med 2014 Dec 16;14:202. Epub 2014 Dec 16.

Department of Pulmonology, Semmelweis University, 1/C Dios arok, Budapest 1125, Hungary.

Background: Electronic noses are composites of nanosensor arrays. Numerous studies showed their potential to detect lung cancer from breath samples by analysing exhaled volatile compound pattern ("breathprint"). Expiratory flow rate, breath hold and inclusion of anatomic dead space may influence the exhaled levels of some volatile compounds; however it has not been fully addressed how these factors affect electronic nose data.

The role of the olfactory recess in olfactory airflow.

J Exp Biol 2014 May 27;217(Pt 10):1799-803. Epub 2014 Feb 27.

Graduate Program in Organismic and Evolutionary Biology, University of Massachusetts Amherst, Amherst, MA 01003, USA Department of Biology, University of Massachusetts Amherst, Amherst, MA 01003, USA.

The olfactory recess - a blind pocket at the back of the nasal airway - is thought to play an important role in mammalian olfaction by sequestering air outside of the main airstream, thus giving odorants time to re-circulate. Several studies have shown that species with large olfactory recesses tend to have a well-developed sense of smell. However, no study has investigated how the size of the olfactory recess relates to air circulation near the olfactory epithelium. Read More
