Engineering Pluripotent Stem Cells‐Derived Inner Ear Organoids With Enhanced Maturation and Reproducibility by Micro‐Topographical Cues

open access: yesAdvanced Materials, EarlyView.
Micro‐topographical cues applied through temporally controlled microscale confinement improve the reproducibility, spatial organization, and neurosensory‐associated features of pluripotent stem cell‐derived inner ear organoids. Integration with a vascularized organoid platform further enables controlled investigation of vascular‐epithelial interactions

Irritability and CATCH [PDF]

open access: yesCanadian Medical Association Journal, 2010
RE: “CATCH: a clinical decision rule for the use of computed tomography in children with minor head injury.” [1][1] This team has done a great job in giving us rural physicians a guiding hand in a clinically difficult situation. However, one thing caught my eye. It was the concept of “

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

open access: yesAdvanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

A Case-Control Study of the Role of Cold Symptoms and other Historical Triggering Factors in Asthma Exacerbations

open access: yesCanadian Respiratory Journal, 2000
BACKGROUND: Asthma exacerbations can be provoked by many triggers such as allergens, respiratory irritants and viral infections. The relative importance of these has not been prospectively documented in a case-control study.

Conformal Thermoreversible Gelatin‐Based Gel for High‐Fidelity Electrophysiological Recording and Acute Peripheral Nerve Interfacing

open access: yesAdvanced Materials, EarlyView.
A thermoreversible gelatin‐based gel forms a soft, conformal bioelectronic interface on complex biological surfaces. The flowable precursor penetrates hair‐dense regions, solidifies in situ, and maintains low impedance through adaptive contact and hydration retention.

Bioengineered Interfaces for Peripheral Nerve Sensory Restoration

open access: yesAdvanced Materials, EarlyView.
Half of amputees abandon their prosthetics for lack of feeling. This review charts the full path from peripheral nerve injury to restored sensation, through surgical, regenerative, noninvasive, and implanted approaches, and shows how injury type and interface material properties determine which strategy can deliver naturalistic feedback, and why ...

Impact of wet work on epidermal barrier (TEWL and stratum corneum hydration) and skin viscoelasticity in nurses

open access: yesMedycyna Pracy, 2014
Background: Nurses are prone to develop hand eczema due to occupational exposure to irritants, including wet work. The aim of the study was to evaluate the impact of wet work on selected skin properties, reflecting epidermal barrier function ...

Irritants and allergens

open access: yes, 2014
Irritants – in this article to be understood as being chemical irritants – are substances that may cause injuries to the skin, the eyes or the airways after a single exposure.

Analysis of differential gene expression in auricular lymph nodes draining skin exposed to sensitizers and irritants

open access: yes, 2007
There has been some concern that certain non-sensitizing irritants may yield false positive results in the murine local lymph node assay (LLNA). This study compared gene expression profiles in lymph nodes draining skin following exposure to sensitizers ...

In Utero Exposure To Second-Hand Smoke Aggravates Adult Responses To Inhaled Irritants [PDF]

open access: yes, 2014
In utero exposure to second-hand smoke (SHS) has modulatory effects on adult lung responses to various irritants. To further elucidate diverse responses with different inhaled irritants and to understand how long the effects persist, we have focused on ...
