Photonic nanojet array for fast detection of single nanoparticles in a flow.

Nano letters

Yang H, Cornaglia M, Gijs MA.
PMID: 25664916
Nano Lett. 2015 Mar 11;15(3):1730-5. doi: 10.1021/nl5044067. Epub 2015 Feb 18.

We detect by optical microscopy Au and fluorescent nanoparticles (NPs) during their motion in water-based medium, using an array of dielectric microspheres that are patterned in a microwell array template. The microspheres act as lenses focusing the light originating...

Skin hyperpigmentation is one of the most common skin disorders caused by abnormal melanogenesis. The mechanism and key factors at play are not fully understood. Previous reports have indicated that cystamine (CTM) inhibits melanin synthesis, though its molecular mechanism...

Amelioration of Cognitive Dysfunction in APP/PS1 Double Transgenic Mice by Long-Term Treatment of 4-O-Methylhonokiol.

Biomolecules & therapeutics

Jung YY, Lee YJ, Choi DY, Hong JT.
PMID: 25009704

Alzheimer's disease (AD) is the most common neurodegenerative disease without known ways to cure. A key neuropathologic manifestation of the disease is extracellular deposition of beta-amyloid peptide (Aβ). Specific mechanisms underlying the development of the disease have not yet...

Ion aggregation in high salt solutions. V. Graph entropy analyses of ion aggregate structure and water hydrogen bonding network.

The Journal of chemical physics

Choi JH, Cho M.
PMID: 27250298
J Chem Phys. 2016 May 28;144(20):204126. doi: 10.1063/1.4952648.

Dissolved ions in water tend to form polydisperse ion aggregates such as ion pairs, relatively compact ion clusters, and even spatially extended ion networks with increasing salt concentration. Combining molecular dynamics simulation and graph theoretical analysis methods, we recently...

Insulin as a Potent Stimulator of Akt, ERK and Inhibin-βE Signaling in Osteoblast-Like UMR-106 Cells.

Biomolecules & therapeutics

Ramalingam M, Kwon YD, Kim SJ.
PMID: 27302964
Biomol Ther (Seoul). 2016 Nov 01;24(6):589-594. doi: 10.4062/biomolther.2016.030.

Insulin is a peptide hormone of the endocrine pancreas and exerts a wide variety of physiological actions in insulin sensitive tissues, such as regulation of glucose homeostasis, cell growth, differentiation, learning and memory. However, the role of insulin in...

Apigenin Regulates Interleukin-1β-Induced Production of Matrix Metalloproteinase Both in the Knee Joint of Rat and in Primary Cultured Articular Chondrocytes.

Biomolecules & therapeutics

Park JS, Kim DK, Shin HD, Lee HJ, Jo HS, Jeong JH, Choi YL, Lee CJ, Hwang SC.
PMID: 26902085
Biomol Ther (Seoul). 2016 Mar 01;24(2):163-70. doi: 10.4062/biomolther.2015.217.

We examined whether apigenin affects the gene expression, secretion and activity of matrix metalloproteinase-3 (MMP-3) in primary cultured rabbit articular chondrocytes, as well as in vivo production of MMP-3 in the knee joint of rat to evaluate the potential...

Accuracy of the detection of binding events using 3D single particle tracking.

BMC biophysics

Carozza S, Culkin J, van Noort J.
PMID: 28344779
BMC Biophys. 2017 Mar 23;10:3. doi: 10.1186/s13628-017-0035-8. eCollection 2017.

BACKGROUND: Nanoparticles can be used as markers to track the position of biomolecules, such as single proteins, inside living cells. The activity of a protein can sometimes be inferred from changes in the mobility of the attached particle. Mean...

Bioorthogonal Chemical Activation of Kinases in Living Systems.

ACS central science

Zhang G, Li J, Xie R, Fan X, Liu Y, Zheng S, Ge Y, Chen PR.
PMID: 27280167
ACS Cent Sci. 2016 May 25;2(5):325-31. doi: 10.1021/acscentsci.6b00024. Epub 2016 Apr 27.

Selective manipulation of protein kinases under living conditions is highly desirable yet extremely challenging, particularly in a gain-of-function fashion. Here we employ our recently developed bioorthogonal cleavage reaction as a general strategy for intracellular activation of individual kinases. Site-specific...

Neuroprotective Effect of Chebulagic Acid via Autophagy Induction in SH-SY5Y Cells.
