BACKGROUND: Dengue is endemic throughout Cambodia, a country faced with significant health and economic challenges. We undertook a clinical study at the National Paediatric Hospital in Phnom Penh to evaluate clinical diagnostic parameters for dengue and predictors of disease...

Successful extracorporeal membrane oxygenation (ECMO) support in two pediatric heart transplant patients with extreme donor/recipient size mismatch.

Journal of thoracic disease

Li P, Dong N, Zhao Y, Gao S.
PMID: 27293854
J Thorac Dis. 2016 Jun;8(6):1329-32. doi: 10.21037/jtd.2016.04.62.

Here we report two cases of extracorporeal membrane oxygenation (ECMO) support in pediatric patients following orthotopic heart transplantation due to low cardiac output and inability to separate from cardiopulmonary bypass (CPB). Both patients had significant donor/recipient size mismatch: ratios...

Triazole-Based Anion-Binding Catalysis for the Enantioselective Dearomatization of N-Heteroarenes with Phosphorus Nucleophiles.

Chemistry (Weinheim an der Bergstrasse, Germany)

Fischer T, Duong QN, García Mancheño O.
PMID: 28111819
Chemistry. 2017 May 02;23(25):5983-5987. doi: 10.1002/chem.201605660. Epub 2017 Feb 16.

The first enantioselective synthesis of chiral heterocyclic α-amino phosphonates by nucleophilic dearomatization of quinolines and pyridines using an anion-binding organocatalysis approach is described. Chiral tetrakistriazoles were employed as efficient hydrogen-bond donor catalysts by forming a chiral close ion-pair with...

High-speed flow microscopy using compressed sensing with ultrafast laser pulses.

Optics express

Bosworth BT, Stroud JR, Tran DN, Tran TD, Chin S, Foster MA.
PMID: 25969092
Opt Express. 2015 Apr 20;23(8):10521-32. doi: 10.1364/OE.23.010521.

We demonstrate an imaging system employing continuous high-rate photonically-enabled compressed sensing (CHiRP-CS) to enable efficient microscopic imaging of rapidly moving objects with only a few percent of the samples traditionally required for Nyquist sampling. Ultrahigh-rate spectral shaping is achieved...
