Photoprotective effects of sphingomyelin-containing milk phospholipids in ultraviolet B–irradiated hairless mice by suppressing nuclear factor-κB expression

Autor: Yejin Ahn, Min G. Kim, Yong J. Choi, Sang J. Lee, Hyung J. Suh, Kyungae Jo

Publikováno v: Journal of Dairy Science, Vol 105, Iss 3, Pp 1929-1939 (2022)

ABSTRACT: Ceramide-containing phospholipids improve skin hydration and barrier function and are ideal for use in skin care products. In this study, we evaluated the photoprotective effect of milk phospholipids on the skin condition of UVB-irradiated

Esculetin induces cell cycle arrest and apoptosis in human colon cancer LoVo cells

Autor: Yong J. Choi, Chang M. Lee, Myeong Jin Nam, See-Hyoung Park

Publikováno v: Environmental Toxicology. 34:1129-1136

We investigated the anti-cancer effects of ESC in human colon cancer LoVo cells. Cell counting assay results showed that ESC inhibited the proliferation of LoVo cells. Cell cycle arrest results showed that cell cycle was arrested during the G0/G1 pha

Cinnamaldehyde suppresses toll-like receptor 4 activation mediated through the inhibition of receptor oligomerization

Autor: Kensuke Miyake, Joo Y. Lee, Daniel H. Hwang, Jun K. Lee, Hyung S. Youn, Yong J. Choi, Shin I. Saitoh

Publikováno v: Biochemical Pharmacology. 75:494-502

Toll-like receptors (TLRs) play a critical role in induction of innate immune and inflammatory responses by recognizing invading pathogens or non-microbial endogenous molecules. TLRs have two major downstream signaling pathways, MyD88- and TRIF-depen

Geometrical design method of multi-degree-of-freedom dynamic vibration absorbers

Autor: Yong J. Choi, Seon Jung Jang

Publikováno v: Journal of Sound and Vibration. 303:343-356

This paper presents a new geometrical design method of multi-degree-of-freedom (mdof) dynamic vibration absorbers that reduce multiple modes of vibration. The design of an mdof vibration absorber involves, in general, the complexity of the equations

The kinematic error bound analysis of the Stewart platform

Autor: Han S. Kim, Yong J. Choi

Publikováno v: Journal of Robotic Systems. 17:63-73

In recent robotics research, the Stewart platform has been increasingly studied for possible use as a machine tool in view of the advantages of high stiffness and accuracy over serial-type manipulators. In designing and controlling a machine tool, ac

The Geometry of Interference With Application to Obstacle Avoidance

Autor: Gary K. Matthew, Joseph Duffy, Carl D. Crane, Yong J. Choi

Publikováno v: Journal of Mechanical Design. 115:300-305

A mapping which transforms the relative displacements of one object with respect to a reference object into image points has been developed by interpreting the relative displacement in terms of affine coordinates. The mapping provides a novel mathema

Obstacle avoidance via articulation

Autor: Yong J. Choi, Gary K. Matthew, Carl D. Crane

Publikováno v: Journal of Robotic Systems. 8:465-484

This article presents a practical implementation of the theory for articulation of spatial robots such as the PUMA and TRS type robots. The “Blueprint Algorithm” is introduced as a simple rule-based planning algorithm in which the geometry of int

Suppression of MyD88- and TRIF-dependent signaling pathways of Toll-like receptor by (-)-epigallocatechin-3-gallate, a polyphenol component of green tea

Autor: Hyung S. Youn, Joo Y. Lee, Daniel H. Hwang, Shin I. Saitoh, Kensuke Miyake, Keon Wook Kang, Yong J. Choi

Publikováno v: Biochemical pharmacology. 72(7)

Toll-like receptors (TLRs) play an important role in recognition of microbial components and induction of innate immunity. The microbial components trigger the activation of two downstream signaling pathways of TLRs; MyD88- and/or TRIF-dependent path
