Front Endocrinol (Lausanne). 2016 Dec 19;7:153. doi: 10.3389/fendo.2016.00153. eCollection 2016.

α-Glucosidase (extinction coefficient 3.2.1.20) is a primary carbohydrate metabolizing enzyme that acts on the 1-4 associated α-glucose residues. The inhibition of α-glucosidase slows down the process of carbohydrate digestion and avoids postprandial hyperglycemia, which is a major cause of...

Epigallocatechin gallate inhibits the growth of MDA-MB-231 breast cancer cells via inactivation of the β-catenin signaling pathway.

Oncology letters

Hong OY, Noh EM, Jang HY, Lee YR, Lee BK, Jung SH, Kim JS, Youn HJ.
PMID: 28693189
Oncol Lett. 2017 Jul;14(1):441-446. doi: 10.3892/ol.2017.6108. Epub 2017 May 02.

Epigallocatechin gallate (EGCG), a major constituent of green tea, has potential as a treatment for a variety of diseases, including cancer. EGCG induces apoptosis and inhibits tumorigenesis through multiple signaling pathways in breast cancer cells. β-catenin signaling modulators could...

Science. 2018 Mar 30;359(6383):1489-1494. doi: 10.1126/science.aan5412.

The controllable incorporation of multiple immiscible elements into a single nanoparticle merits untold scientific and technological potential, yet remains a challenge using conventional synthetic techniques. We present a general route for alloying up to eight dissimilar elements into single-phase...

Electrocatalytic CO.

Chem Commun (Camb). 2018 Mar 29;54(27):3351-3354. doi: 10.1039/c8cc00266e.

A series of nickel complexes featuring redox-active macrocycles is reported for electrocatalytic CO2 reduction. A remarkable structure-activity relationship is elucidated from the series through electrochemical studies and DFT calculations, wherein a fine electronic balance between metal and ligand redox...

Thickness-Controlled Quasi-Two-Dimensional Colloidal PbSe Nanoplatelets.

Journal of the American Chemical Society

Koh WK, Dandu NK, Fidler AF, Klimov VI, Pietryga JM, Kilina SV.
PMID: 28099009
J Am Chem Soc. 2017 Feb 15;139(6):2152-2155. doi: 10.1021/jacs.6b11945. Epub 2017 Jan 31.

We demonstrate controlled synthesis of discrete two-dimensional (2D) PbSe nanoplatelets (NPLs), with measurable photoluminescence, via oriented attachment directed by quantum dot (QD) surface chemistry. Halide passivation is critical to the growth of these (100) face-dominated NPLs, as corroborated by...
