Mechanosensation is the ability to detect dynamic mechanical stimuli (e.g., pressure, stretch, and shear stress) and is essential for a wide variety of processes, including our sense of touch on the skin. How touch is detected and transduced at the molecular level has proved to be one of the great mysteries of sensory biology. A major breakthrough occurred in 2010 with the discovery of a family of mechanically gated ion channels that were coined PIEZOs. The last 10 years of investigation have provided a wealth of information about the functional roles and mechanisms of these molecules. Here we focus on PIEZO2, one of the two PIEZO proteins found in humans and other mammals. We review how work at the molecular, cellular, and systems levels over the past decade has transformed our understanding of touch and led to unexpected insights into other types of mechanosensation beyond the skin.In eukaryotes, transcription of protein-coding genes requires the assembly at core promoters of a large preinitiation machinery containing RNA polymerase II (RNAPII) and general transcription factors (GTFs). Transcription is potentiated by regulatory elements called enhancers, which are recognized by specific DNA-binding transcription factors that recruit cofactors and convey, following chromatin remodeling, the activating cues to the preinitiation complex. This review summarizes nearly five decades of work on transcription initiation by describing the sequential recruitment of diverse molecular players including the GTFs, the Mediator complex, and DNA repair factors that support RNAPII to enable RNA synthesis. The elucidation of the transcription initiation mechanism has greatly benefited from the study of altered transcription components associated with human diseases that could be considered transcription syndromes.
The aim was to investigate how leading dentists and their superiors view oral health care quality, as they are in key positions to pursue high-quality care.

We interviewed five leading dentists and three of their superiors from Southern Finland via semi-structured telephone interviews including themes based on the Institute of Medicine's six quality dimensions. The material was analysed using theory-driven content analysis.

Participants divided safety into occupational, instrumental and patient safety and considered timeliness as timing treatment clinically correctly. They also linked timeliness to patient-centeredness with wider opening-hours and quick access to care. Effective care was considered as a prerequisite for efficiency. MAPK inhibitor Participants saw effectiveness as treating the illness, not the number of treatment measures. Leading dentists took survival time of fillings and cost per operation as a measurement of efficiency, and the superiors measured efficiency by the number of treated patients or visits. The leading dentists considered the equal treatment of patients, whereas the superiors took the amount of care provided with public resources and co-workers into consideration.

The participants shared similar views of oral health care quality which should enable cooperation. Observed minor differences relate to professional background and leading positions.

In the current viewpoint, we first lay out the main issues that are central to the controversy surrounding APD, and then suggest a framework toward their resolution. Method The current viewpoint is informed by reviewing existing studies in the field of APD to better understand the issues contributing to the controversies in APD. Results We found that, within the current definition of APD, the two main issues that make the APD diagnosis controversial are (a) comorbidity with other disorders and (b) the lack of domain specificity. These issues remain unresolved, especially with the use of the existing behavioral APD test batteries. In this viewpoint, we shed light on how they can be mitigated by implementing the administration of an objective, physiological test battery. Conclusions By administering an objective test battery, as proposed in this viewpoint, we believe that it will be possible to achieve a higher degree of specificity to the auditory domain that will not only contribute towards clinical practice but also contribute towards strengthening APD as a theoretical construct.Purpose The COVID-19 pandemic has necessitated a quick shift to virtual speech-language services; however, only a small percentage of speech-language pathologists (SLPs) had previously engaged in telepractice. The purpose of this clinical tutorial is (a) to describe how the Early Language and Literacy Acquisition in Children with Hearing Loss study, a longitudinal study involving speech-language assessment with children with and without hearing loss, transitioned from in-person to virtual assessment and (b) to provide tips for optimizing virtual assessment procedures. Method We provide an overview of our decision making during the transition to virtual assessment. Additionally, we report on a pilot study that calculated test-retest reliability from in-person to virtual assessment for a subset of our preschool-age participants. Results Our pilot study revealed that most speech-language measures had high or adequate test-retest reliability when administered in a virtual environment. When low reliability occurred, generally the measures were timed. Conclusions Speech-language assessment can be conducted successfully in a virtual environment for preschool children with hearing loss. We provide suggestions for clinicians to consider when preparing for virtual assessment sessions. Supplemental Material https//doi.org/10.23641/asha.14787834.Purpose This study compares two electromagnetic articulographs manufactured by Northern Digital, Inc. the NDI Wave System (from 2008) and the NDI Vox-EMA System (from 2020). Method Four experiments were completed (a) comparison of statically positioned sensors, (b) tracking dynamic movements of sensors manipulated using a motor-driven LEGO apparatus, (c) tracking small and large movements of sensors mounted in a rigid bar manipulated by hand, and (d) tracking movements of sensors rotated on a circular disc. We assessed spatial variability for statically positioned sensors, variability in the transduced Euclidean distances between sensor pairs, and missing data rates. For sensors tracking circular movements, we compared the fit between fitted ideal circles and actual trajectories. Results The average sensor pair tracking error (i.e., the standard deviation of the Euclidean distances) was 1.37 mm for the WAVE and 0.12 mm for the VOX during automated trials at the fastest speed, and 0.35 mm for the WAVE and 0.14 mm for the VOX during the tracking of large manual movements.
