Abstract

Linear nevus sebaceous syndrome (LNSS) is a neurocutaneous disorder caused by somatic gain-of-function mutations in KRAS or HRAS. LNSS brains have neurodevelopmental defects, including cerebral defects and epilepsy; however, its pathological mechanism and potentials for treatment are largely unclear. We show that introduction of KRAS G12V in the developing mouse cortex results in subcortical nodular heterotopia and enhanced excitability, recapitulating major pathological manifestations of LNSS. Moreover, we show that decreased firing frequency of inhibitory neurons without KRASG12V expression leads to disrupted excitation and inhibition balance. Transcriptional profiling after destabilization domain-mediated clearance of KRASG12V in human neural progenitors and differentiating neurons identifies reversible functional networks underlying LNSS. Neurons expressing KRASG12V show molecular changes associated with delayed neuronal maturation, most of which are restored by KRASG12V clearance. These findings provide insights into the molecular networks underlying the reversibility of some of the neuropathologies observed in LNSS caused by dysregulation of the RAS pathway. [Display omitted] • Introduction of KRASG12V in developing cortex recapitulates LNSS neuropathologies • Clearance of KRASG12V defines reversible and persistent molecular networks • Findings provide insights into pathomechanisms and potential for treatment Kim et al. establish an animal and human neural progenitor cell-based model of linear nevus sebaceous syndrome caused by mutations activating the RAS pathway. Clearance of the disease-causing protein identifies reversible functional networks. Their results provide insights into reversible networks and potential for treatment. [ABSTRACT FROM AUTHOR]

Abstract

The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ‘risk’ and ‘safety margin’ respectively. Rear-end collision had a stronger focus in the present study. As a result of accident analysis, heavy truck showed a higher susceptibility of the fatal rear-end accidents than car and light truck. Also, dry road surface compared to wet or snow, dark condition compared to daylight condition, straight road compared to curved road, level road compared to grade, crest or sag, roadway having more than 5 travel lanes compared to roadway having 2, 3 or 4 travel lanes showed a higher susceptibility of the fatal rear-end accidents. Relative rear-end accidents involvement proportion compared to the other types of collision was used as a measure of susceptibility. As a result of quantitative analysis, a significant difference in terms of Required Minimum Warning Distance (RMWD) was made among a different vehicle type and braking system group. However, relatively small difference was made among a different age, gender group in terms of RMWD. Based on the result, breaking performance of vehicle should be regarded as an input variable in the design of CWS, specifically warning timing criteria, was concluded.

Abstract

Invited for this month's cover is a combined work of the Korea Research Institute of Chemical Technology together with the Chungnam National University, the University of California, Irvine, and Chung‐Ang University. The cover shows the effective thermal management of a vehicle interior through the wrapping of stretchable passive radiative cooling film. Thermoplastic polyurethane (TPU) cooler film with a hierarchical porous structure shows a dramatic cooling effect compared to commercial paint in sunny, hot weather. The Research Article itself is available at 10.1002/cssc.202201842. [ABSTRACT FROM AUTHOR]
