Influence of Loudness, Pitch, Vowel, and Voice Condition on Supraglottic Tissue Displacement in Female Participants.

Purpose: The present study aims at exploring the effect of pitch, loudness, vowel, and voice condition on supraglottic activity among female participants with voice disorders and among female participants with normal voices.

Methods: Forty-four volunteers were recruited. Inclusion criteria for the dysphonic group were: 1) age between 20 and 50 years, 2) reporting at least 1 year-long history of voice problems, 3) moderate or severe dysphonia.

Evaluation of a Non-Enzymatic Electrochemical Sensor Based on Co(OH)-Functionalized Carbon Nanotubes for Glucose Detection.

This work reports on the assessment of a non-hydrolytic electrochemical sensor for glucose sensing that is developed using functionalized carbon nanotubes (fCNTs)/Co(OH). The morphology of the nanocomposite was investigated by scanning electron microscopy, which revealed that the CNTs interacted with Co(OH). This content formed a nanocomposite that improved the electrochemical characterizations of the electrode, including the electrochemical active surface area and capacitance, thus improving sensitivity to glucose.

Enhancing intestinal absorption of a macromolecule through engineered probiotic yeast in the murine gastrointestinal tract.

Oral administration of therapeutic peptides is limited by poor intestinal absorption. Use of engineered microorganisms as drug delivery vehicles can overcome the challenges faced by conventional delivery methods. The potential of engineered microorganisms to act synergistically with the therapeutics they deliver opens new horizons for noninvasive treatment modalities.

BMP signaling pathway member expression is enriched in enteric neural progenitors and required for zebrafish enteric nervous system development.

Background: The vertebrate enteric nervous system (ENS) consists of a series of interconnected ganglia within the gastrointestinal (GI) tract, formed during development following migration of enteric neural crest cells (ENCCs) into the primitive gut tube. Much work has been done to unravel the complex nature of extrinsic and intrinsic factors that regulate processes that direct migration, proliferation, and differentiation of ENCCs. However, ENS development is a complex process, and we still have much to learn regarding the signaling factors that regulate ENCC development.
