Mechanotransduction of vocal fold fibroblasts and mesenchymal stromal cells in the context of the vocal fold mechanome.

J Biomech 2018 Dec 7. Epub 2018 Dec 7.

Department of Surgery, Division of Otolaryngology-Head and Neck Surgery, University of Wisconsin-Madison, Madison, WI, United States. Electronic address:

The design of cell-based therapies for vocal fold tissue engineering requires an understanding of how cells adapt to the dynamic mechanical forces found in the larynx. Our objective was to compare mechanotransductive processes in therapeutic cell candidates (mesenchymal stromal cells from adipose tissue and bone marrow, AT-MSC and BM-MSC) to native cells (vocal fold fibroblasts-VFF) in the context of vibratory strain. A bioreactor was used to expose VFF, AT-MSC, and BM-MSC to axial tensile strain and vibration at human physiological levels. Read More

Andrea Ravignani

J Comp Psychol 2018 Dec 13. Epub 2018 Dec 13.

Research Department, Sealcentre Pieterburen.

Alternative mathematical models predict differences in how animals adjust the timing of their calls. Differences can be measured as the effect of the timing of a conspecific call on the rate and period of calling of a focal animal, and the lag between the two. Here, I test these alternative hypotheses by tapping into harbor seals' (Phoca vitulina) mechanisms for spontaneous timing. Read More

Real-Time Light-Guided Vocal Fold Injection: Ex Vivo Feasibility Study in a Canine Model.

Laryngoscope 2018 Dec 12. Epub 2018 Dec 12.

Department of Otorhinolaryngology-Head and Neck Surgery and Biomedical Research Institute, Republic of Korea.

Objective: The transcricothyroid (CT) membrane approach is a good option for office-based vocal fold injection (VFI). However, because the needle tip is invisible during injection using the CT approach, precise localization requires a high level of experience, and mastering this approach involves a steep learning curve. To overcome current limitations, we conceptualized a novel technique: real-time light-guided VFI (RL-VFI), which enables simultaneous VFI under direct visualization of the lighted needle tip.

Program in Neuroscience, Florida State University, Tallahassee, Florida 32306-4301

Song learning in zebra finches () requires exposure to the song of a tutor, resulting in an auditory memory. This memory is the foundation for later sensorimotor learning, resulting in the production of a copy of the tutor's song. The cortical premotor nucleus HVC (proper name) is necessary for auditory and sensorimotor learning as well as the eventual production of adult song. Read More

Ability to process musical pitch is unrelated to the memory advantage for vocal music.

Brain Cogn 2018 Dec 3. Epub 2018 Dec 3.

International Laboratory for Brain, Music, and Sound Research, Canada; Department of Psychology, Université de Montréal, Montréal, Canada.

Listeners remember vocal melodies better than instrumental melodies, but the origins of the effect are unclear. One explanation for the 'voice advantage' is that general perceptual mechanisms enhance processing of conspecific signals. An alternative possibility is that the voice, by virtue of its expressiveness in pitch, simply provides more musical information to the listener. Read More

Differential developmental changes in cortical representations of auditory-vocal stimuli in songbirds.

J Neurophysiol 2018 Dec 12. Epub 2018 Dec 12.

University of Southern California, United States.

Procedural skill learning requires iterative comparisons between feedback of self-generated motor output and a goal sensorimotor pattern. In juvenile songbirds, neural representations of both self-generated behaviors (each bird's own immature song) and the goal motor pattern (each bird's adult tutor song) are essential for vocal learning, yet little is known about how these behaviorally relevant stimuli are encoded. We made extracellular recordings during song playback in anesthetized juvenile and adult zebra finches ( Taeniopygia guttata) in adjacent cortical regions RA (robust nucleus of the arcopallium), AId (dorsal intermediate arcopallium), and RA-cup, each of which is well-situated to integrate auditory-vocal information: RA is a motor cortical region that drives vocal output, AId is an adjoining cortical region whose projections converge with basal ganglia loops for song learning in the dorsal thalamus, and RA-cup surrounds RA and receives inputs from primary and secondary auditory cortex.

Sclerosis of the arytenoid cartilage and glottic carcinoma: A clinical-pathological study.

Head Neck 2018 Dec 7. Epub 2018 Dec 7.

Otolaryngology Unit, Vittorio Veneto Hospital, Treviso, Italy.

Background: Given the relevance of any tumor invasion of the arytenoid cartilage or crico-arytenoid unit to the planning open partial horizontal laryngectomy (OPHL) for laryngeal squamous cell carcinoma (LSCC), it is important to have a reliable radiological test to assess impairments of these structures.

Methods: We retrospectively compared the endoscopic, radiological, and pathological findings in patients with glottic LSCC who underwent OPHL.

Results: The endoscopic finding of a reduced (impaired or absent) vocal cord motility proved more sensitive, with better positive and negative predictive values, but less specific than the radiological finding of complete arytenoid sclerosis in detecting histologically assessable infiltration of the arytenoid cartilage.

An extended Levinson-Durbin algorithm and its application in mixed excitation linear prediction.

Heliyon 2018 Nov 24;4(11):e00948. Epub 2018 Nov 24.

Key Laboratory of Underwater Acoustic Environment, Institute of Acoustics, Chinese Academy of Sciences, China.

Ten order all-pole model is used in the 2400 bit/second mixed excitation linear prediction to describe human vocal tract. Traditional Levinson-Durbin algorithm is one of the methods to solve the Yule-Walker equations conducted by the ten order linear prediction model. Taking the iteration step of traditional Levinson-Durbin algorithm as 1, an extended algorithm with any positive integer iteration step which is no larger than the order of Teoplitz matrix is proposed.

Carbon Dioxide Laser Microsurgery versus Low-Temperature Plasma Radiofrequency Ablation for T1a Glottic Cancer: A Single-Blind Randomized Clinical Trial.

Biomed Res Int 2018 1;2018:4295960. Epub 2018 Nov 1.

Department of Otolaryngology, The Third Hospital of Wuhan City, Wuhan, Hubei Province, China.

Background: Very few studies have been conducted to compare carbon dioxide laser microsurgery (CO2-LS) with low-temperature plasma radiofrequency ablation (LTP-RFA) in treating T1a glottic cancer. Therefore, we conducted this study to compare the efficacy of CO2-LS and LTP-RFA to define a superior therapeutic modality for T1a glottic cancer.

Methods: Patients (n=131) with T1a glottic cancer were recruited between January 2010 and September 2014. Read More

Open-neck organ preservation surgery for hypopharyngeal cancer: indications, techniques, limits, and outcomes.

Curr Opin Otolaryngol Head Neck Surg 2018 Nov 16. Epub 2018 Nov 16.

Department of Otolaryngology, Head and Neck Surgery, Beijing Friendship Hospital, Capital Medical University, Beijing, China.

Purpose Of Review: To appraise the practice and role of open-neck organ preserving surgery for hypopharyngeal squamous cell carcinoma and to update the current indications, techniques, limits, and outcomes.

Recent Findings: The role of primary surgery for hypopharyngeal carcinoma has shifted over the past two decades to primary nonsurgical management with the use of induction or concurrent chemoradiotherapy. The preferred and most suitable tumours for open-neck surgery are the small-volume T stage diseases, with small to medium-volume neck metastases, however such patients are exceedingly rare.

Impact of completion thyroidectomy timing on post-operative complications: a systematic review and meta-analysis.

Gland Surg 2018 Oct;7(5):458-465

Department of Surgery, King Khalid University Hospital, Riyadh, Saudi Arabia.

Background: Despite a number of studies, the optimal timing of completion thyroidectomy is still controversial. This systematic review and meta-analysis aims to compare the outcomes of early versus delayed completion thyroidectomy regarding post-operative complications.

Methods: We performed a systematic review in electronic databases including: bumped, Scopus, Medline and Google Scholar to identify relevant studies. Read More
