Neuronal SNARE complex assembly guided by Munc18‐1 and Munc13‐1

open access: yesFEBS Open Bio, Volume 12, Issue 11, Page 1939-1957, November 2022., 2022
Munc18‐1 and Munc13‐1 regulate synaptic vesicle exocytosis via orchestrating neuronal SNARE complex (syntaxin‐1, SNAP‐25, and synaptobrevin‐2) assembly. In this review, we summarized recent advances towards the molecular mechanisms of Munc18‐1 and Munc13‐1 in guiding neuronal SNARE complex assembly and discussed the similarities and differences between

What helps distressed Australian adolescents impacted by cancer? Mechanisms of improvement of the PEER program

open access: yesHealth &Social Care in the Community, Volume 30, Issue 6, Page e4673-e4683, November 2022., 2022
Abstract PEER is a four‐day residential program for adolescents impacted by their own or a relative's cancer, with both psychosocial (acceptance and commitment therapy, self‐compassion) and recreational components. This study aimed to determine whether previously observed improvements in quality of life amongst highly distressed participants were ...

Quantifying the Impact of Synoptic Weather Systems on High PM2.5 Episodes in the Seoul Metropolitan Area, Korea

open access: yesJournal of Geophysical Research: Atmospheres, Volume 126, Issue 10, 27 May 2021., 2021
Abstract Variations in concentrations of PM2.5, particulate matters of diameters below 2.5 μm, vary following both meteorological conditions and emissions controls. Meteorological conditions particularly affect short‐term high PM2.5 episodes through accumulations, transports, and secondary formations. This study quantifies the meteorological impacts on

Bottom‐Up Approach Ship Emission Inventory in Port of Incheon Based on VTS Data

open access: yesJournal of Advanced Transportation, Volume 2021, Issue 1, 2021., 2021
As a result of the rapid growth of international trade, atmospheric pollution from transportation has been more topical than ever, especially in dense hub port‐cities. The shipping industry should pay more attention corresponding to its contribution to local atmospheric pollution.

Secretory Vesicle Priming by CAPS Is Independent of Its SNARE-Binding MUN Domain

open access: yesCell Reports, 2014
Priming of secretory vesicles is a prerequisite for their Ca2+-dependent fusion with the plasma membrane. The key vesicle priming proteins, Munc13s and CAPSs, are thought to mediate vesicle priming by regulating the conformation of the t-SNARE syntaxin ...

Unambiguous joint detection of spatially separated properties of a single photon in the two arms of an interferometer

open access: yesCommunications Physics, 2023
The quantum superposition principle implies that a particle entering an interferometer evolves by simultaneously taking both arms. If a non-destructive, minimally-disturbing interaction coupling a particle property to a pointer is implemented on each arm

Impact of Aviation Emissions and its Changes Due to the COVID-19 Pandemic on Air Quality in South Korea

open access: yesAtmosphere, 2022
This study analyzed the impact of aviation emissions based on the 2017 CAPSS (Clean Air Policy Support System) data. We focused on major airports in South Korea and examined the concentration of NO2 and PM2.5 by the WRF-SMOKE-CMAQ modeling system ...
