Intranasal Insulin Prevents Anesthesia-Induced Cognitive Impairment and Chronic Neurobehavioral Changes.

Frontiers in aging neuroscience

Chen Y, Dai CL, Wu Z, Iqbal K, Liu F, Zhang B, Gong CX.
PMID: 28539885
Front Aging Neurosci. 2017 May 10;9:136. doi: 10.3389/fnagi.2017.00136. eCollection 2017.

General anesthesia increases the risk for cognitive impairment post operation, especially in the elderly and vulnerable individuals. Recent animal studies on the impact of anesthesia on postoperative cognitive impairment have provided some valuable insights, but much remains to be...

Unusually Stable Helical Coil Allotrope of Phosphorus.

Nano letters

Liu D, Guan J, Jiang J, Tománek D.
PMID: 27960488
Nano Lett. 2016 Dec 14;16(12):7865-7869. doi: 10.1021/acs.nanolett.6b04128. Epub 2016 Dec 05.

We have identified an unusually stable helical coil allotrope of phosphorus. Our ab initio density functional theory calculations indicate that the uncoiled, isolated straight one-dimensional chain is equally stable as a monolayer of black phosphorus dubbed phosphorene. The coiling...

Accessing the Inaccessible: Redefining Play as a Spectrum.

Frontiers in psychology

Zosh JM, Hirsh-Pasek K, Hopkins EJ, Jensen H, Liu C, Neale D, Solis SL, Whitebread D.
PMID: 30116208
Front Psychol. 2018 Aug 02;9:1124. doi: 10.3389/fpsyg.2018.01124. eCollection 2018.

Defining play has plagued researchers and philosophers for years. From describing play as an inaccessible concept due to its complexity, to providing checklists of features, the field has struggled with how to conceptualize and operationalize "play." This theoretical piece...

Baicalin attenuates liver hypoxia/reoxygenation injury by inducing autophagy.

Experimental and therapeutic medicine

Liu F, Zhang J, Qian J, Wu G, Ma Z.
PMID: 30116320
Exp Ther Med. 2018 Aug;16(2):657-664. doi: 10.3892/etm.2018.6284. Epub 2018 Jun 08.

The aim of the present study was to explore the effect of baicalin on liver hypoxia/reoxygenation (H/R) injury and the possible mechanism involved. A cellular H/R model was established and cells were treated with 50, 100 and 200 µmol/l...

High-Strength Nanocomposite Aerogels of Ternary Composition: Poly(vinyl alcohol), Clay, and Cellulose Nanofibrils.

ACS applied materials & interfaces

Liu A, Medina L, Berglund LA.
PMID: 28155270
ACS Appl Mater Interfaces. 2017 Feb 22;9(7):6453-6461. doi: 10.1021/acsami.6b15561. Epub 2017 Feb 10.

Clay aerogels are foam-like materials with potential to combine high mechanical performance with fire retardancy. However, the compression strength of these aerogels is much lower than theoretically predicted values. High-strength aerogels with more than 95% porosity were prepared from...

Nonnegative Matrix Factorization with Rank Regularization and Hard Constraint.

Neural computation

Shang R, Liu C, Meng Y, Jiao L, Stolkin R.
PMID: 28777717
Neural Comput. 2017 Sep;29(9):2553-2579. doi: 10.1162/neco_a_00995. Epub 2017 Aug 04.

Nonnegative matrix factorization (NMF) is well known to be an effective tool for dimensionality reduction in problems involving big data. For this reason, it frequently appears in many areas of scientific and engineering literature. This letter proposes a novel...

The Chemistry of 1-Acylphosphirane Complexes: A Phosphorus Analogue of the Cloke-Wilson Rearrangement.

Chemistry (Weinheim an der Bergstrasse, Germany)

Tian R, Zhang C, Xu Y, Liu C, Duan Z, Mathey F.
PMID: 28691200
Chemistry. 2017 Sep 21;23(53):13006-13009. doi: 10.1002/chem.201702722. Epub 2017 Aug 23.

The stabilization of a phosphirane ring by complexation to tungsten pentacarbonyl allows the emergence of the Cloke-Wilson rearrangement in 1-acylphosphirane complexes around 130 °C. Contrary to the cyclopropane case, this transformation of the 1-acylphosphirane to the 1,3-oxaphosphol-3-ene complexes is...

Electrostatic Polysulfides Confinement to Inhibit Redox Shuttle Process in the Lithium Sulfur Batteries.

ACS applied materials & interfaces
