A Vertically‐Stacked Optoelectronic Sensor for Localized Hemodynamics Monitoring

Advanced Functional Materials, EarlyView.
This work introduces a hemodynamics monitoring sensor that features vertically stacked microLEDs and a heterogeneously integrated photodetector. The vertically stacked microLEDs enable localized measurements, and by designing the interoptode distance according to the depth of the target region, this vertically stacked optoelectronic sensor is ...

Simultaneous two-layer harvesting of scalp split-thickness skin and dermal grafts for acute burns and postburn scar deformities

Archives of Plastic Surgery, 2019
Background The scalp, an excellent donor site for thin skin grafts, presents a limited surface but is rich in stem cells. The purpose of this study was to test a double harvesting procedure from the scalp and to evaluate the capacity of the dermal layer.

Comparison of Healthy and Dandruff Scalp Microbiome Reveals the Role of Commensals in Scalp Health

Frontiers in Cellular and Infection Microbiology, 2018
Several scalp microbiome studies from different populations have revealed the association of dandruff with bacterial and fungal dysbiosis. However, the functional role of scalp microbiota in scalp disorders and health remains scarcely explored.

Error-related scalp potentials elicited by hand and foot movements : evidence for an output-independent error-processing system in humans

, 1998
The error-related negativity (ERN) is a fronto-centrally distributed component of the event-related brain potential (ERP) that occurs when human subjects make errors in a variety of experimental tasks.

Transducer Materials Mediated Deep Brain Stimulation in Neurological Disorders

Advanced Functional Materials, EarlyView.
This review discusses advanced transducer materials for improving deep brain stimulation (DBS) in neurological disorders. These materials respond to light, ultrasound, or magnetic fields, enabling precise, less invasive neuromodulation. Their stimulus‐responsive properties enhance neural control and adaptive therapy, paving the way for next‐generation ...

Functional Hydrogel for Modulating Lipid Droplets and Neuroinflammation in Head Injury

Advanced Functional Materials, EarlyView.
After TBI, elevated cholesterol levels in activated microglia lead to the accumulation of cholesterol esters in lipid droplets, exacerbating neuroinflammation. A β‐cyclodextrin‐conjugated GelMA (βCD‐GelMA) hydrogel is developed to promotes cholesterol efflux and reduces LDL influx, thereby alleviating intracellular cholesterol and lipid droplet buildup.

A computer-based simulation of vacuum extraction during childbirth [PDF]

, 2014
Vacuum extraction is an instrumental method used in obstetrics when childbirth labour fails to progress. The instrument used during vacuum extraction is the ventouse. It comprises of a suction cup attached to the fetal scalp through a vacuum, and a chord

The resting microstate networks (RMN): cortical distributions, dynamics, and frequency specific information flow [PDF]

, 2014
A brain microstate is characterized by a unique, fixed spatial distribution of electrically active neurons with time varying amplitude. It is hypothesized that a microstate implements a functional/physiological state of the brain during which specific ...

Polymer‐Incorporated Mechanically Compliant Carbon Nanotube Microelectrode Arrays for Multichannel Neural Signal Recording

Advanced Functional Materials, EarlyView.
This work presents a soft microelectrode array based on vertically aligned carbon nanotube (CNT) forests, combining high conductivity with mechanical softness. A densification process and air‐pressure‐assisted flexibilization improve structural integrity, ensuring stable insertion and reduced inflammation.
