Two-dimensional nature of the active Brownian motion of catalytic microswimmers at solid and liquid interfaces

New Journal of Physics, 2017
Colloidal particles equipped with platinum patches can establish chemical gradients in H _2 O _2 -enriched solutions and undergo self-propulsion due to local diffusiophoretic migration.

Retinal structure and function recovery over five years in Vogt-Koyanagi-Harada disease using adaptive optics and microperimetry

Scientific Reports
Vogt-Koyanagi-Harada (VKH) disease recovery patterns remain inadequately characterized over extended periods. This study evaluated retinal changes in VKH patients across 5 years using adaptive optics imaging and microperimetry.

Developmental divergence of sensory stimulus representation in cortical interneurons

Nature Communications, 2020
Sensory neuronal circuits adapt during maturation when animals start to actively interact with the external world. The authors reveal structural and functional rearrangements of the input cortical interneurons receive around the time the animals start ...

Evaluating staging laparoscopy indications for pancreatic cancer based on resectability classification and treatment strategies for patients with positive peritoneal washing cytology

Annals of Gastroenterological Surgery
Introduction The prognosis of pancreatic ductal adenocarcinoma (PDAC) in patients with positive peritoneal washing cytology (CY1) is poor. We aimed to evaluate the results of staging laparoscopy (SL) and treatment efficacy in CY1 patients based on a ...

Risk Evaluation of the NCD Risk Calculator for Open Pancreaticoduodenectomy in Elderly Patients: A Validation Study

Annals of Gastroenterological Surgery
Background There is no clear indication for surgery in pancreaticoduodenectomy (PD) for the elderly patients. The aim of this study was to use real‐world data to investigate the usefulness of preoperative risk assessment with the risk calculator ...

Effect of tumour necrotic factor‐α, interleukin‐17 and interleukin‐22 on the expression of filaggerin‐2 and hornerin: Analysis of a three‐dimensional psoriatic skin model

Skin Health and Disease
Background Filaggrin‐2 (FLG2) and hornerin (HRNR) are members of the S100 fused‐type protein family, which share many properties with filaggrin (FLG). A previous study demonstrated that the expression of FLG2 was significantly decreased in psoriatic skin

A Real-Time Path Planning Algorithm for AUV in Unknown Underwater Environment Based on Combining PSO and Waypoint Guidance

Sensors, 2018
It is a challengeable task to plan multi-objective optimization paths for autonomous underwater vehicles (AUVs) in an unknown environments, which involves reducing travel time, shortening path length, keeping navigation safety, and smoothing trajectory ...

Novel choledochojejunostomy technique “T‐shaped anastomosis” for preventing the development of postoperative cholangitis in pancreatoduodenectomy: A propensity score matching analysis

Annals of Gastroenterological Surgery
Background There have been few studies of countermeasures against postoperative cholangitis, a serious complication after pancreaticoduodenectomy (PD) that impairs quality of life.

A Real-Time Reaction Obstacle Avoidance Algorithm for Autonomous Underwater Vehicles in Unknown Environments

Sensors, 2018
A novel real-time reaction obstacle avoidance algorithm (RRA) is proposed for autonomous underwater vehicles (AUVs) that must adapt to unknown complex terrains, based on forward looking sonar (FLS).

Developmental Cajal-Retzius cell death contributes to the maturation of layer 1 cortical inhibition and somatosensory processing

Nature Communications
The role of developmental cell death in the formation of brain circuits is not well understood. Cajal-Retzius cells constitute a major transient neuronal population in the mammalian neocortex, which largely disappears at the time of postnatal ...
