Development of Selective Plane Illumination Surface Enhanced Raman Scattering Spectral Microscopy for Improved Cellular Imaging

Journal of Raman Spectroscopy, EarlyView.
Selective plane illumination (SPI) is combined with SERS spectral imaging to reduce background, improve image contrast, and enable improved spectroscopy from molecules on the surface of nanoparticles. This approach provides improved imaging and spectroscopy from nanoparticles in complex environments, such as biological cells.

Magnetically shielded high-resolution visual stimulation for OPM-MEG applications

Biomedical Physics & Engineering Express
Abstract Many magnetoencephalography (MEG) experiments require visual stimulation (VS) inside a magnetically shielded room (MSR). For conventional MEG utilizing superconducting quantum interference devices (SQUIDs), the participant’s head must stay within the semi-spherical surface of a cryogenic storage Dewar. This design allows to have

Measuring the neurodevelopmental trajectory of excitatory-inhibitory balance via visual gamma oscillations [PDF]

Disruption of the balance between excitatory and inhibitory neurotransmission (E-I balance) is thought to underlie many neurodevelopmental disorders; however, its study is typically restricted to adults, animal models and the lab-bench ...

LRRK2 as a Potential Disease‐Modifying Target in Sporadic Parkinson's Disease

Movement Disorders, EarlyView.
Abstract A growing understanding of the role that leucine‐rich repeat kinase 2 (LRRK2) plays in Parkinson's disease (PD) supports continued focus on this enzyme as a therapeutic target for PD. Accumulating evidence suggests that there are phenotypic, neuropathologic, and biological similarities between sporadic PD (sPD) and familial forms in which ...

Detection of the 40 Hz auditory steady-state response with optically pumped magnetometers

Scientific Reports, 2022
Magnetoencephalography (MEG) is a functional neuroimaging technique that noninvasively detects the brain magnetic field from neuronal activations. Conventional MEG measures brain signals using superconducting quantum interference devices (SQUIDs).

Anatomically Veridical On‐Scalp Sensor Topographies [PDF]

When working with sensor‐level data recorded using on‐scalp neuroimaging methods such as electroencephalography (EEG), it is common practice to use two‐dimensional (2D) representations of sensor positions to aid interpretation.

Comparative Efficacy of Metabolic/Bariatric Surgery Versus GLP‐1 Receptor Agonists: A Network Meta‐Analysis of Randomized Controlled Trials

Obesity, EarlyView.
ABSTRACT Objective This study compared the efficacy of metabolic/bariatric surgery (MBS) and GLP‐1 receptor agonists (GLP‐1 RAs), including dual GLP‐1/GIP analogues, for weight and metabolic outcomes in adults with obesity. Methods A network meta‐analysis of randomized controlled trials compared MBS or GLP‐1 RAs versus lifestyle intervention in adults ...

System Design Considerations for Magneto‐Electrocatalysis of the Oxygen Evolution Reaction

Small, EarlyView.
Electrocatalytic water‐splitting can be controlled using a magnetic field. The commercial prospects are exciting, but the progress is stuck in the fundamental stage of research. Progress is stagnated by publications with conflicting results, incomplete analysis, and inconsistent experimental setups.

A Bibliometric Review of the INCOSE's Model‐Based Systems Engineering Roadmap

Systems Engineering, EarlyView.
ABSTRACT Over the past decade, model‐based systems engineering (MBSE) has gained attention as an approach for managing system complexity, offering a shift from a document‐based to a model‐based approach. The International Council on Systems Engineering (INCOSE) sparked increasing interest when it introduced MBSE and its roadmap as part of its systems ...
