Exploiting Benzophenone Photoreactivity To Probe the Phospholipid Environment and Insertion Depth of the Cell-Penetrating Peptide Penetratin in Model Membranes.

Angewandte Chemie (International ed. in English)

Jiao CY, Sachon E, Alves ID, Chassaing G, Bolbach G, Sagan S.
PMID: 28485523
Angew Chem Int Ed Engl. 2017 Jul 03;56(28):8226-8230. doi: 10.1002/anie.201703465. Epub 2017 Jun 06.

Penetratin (RQIKIWFQNRRMKWKK) enters cells by different mechanisms, including membrane translocation, thus implying that the peptide interacts with the lipid bilayer. Penetratin also crosses the membrane of artificial vesicles, depending on their phospholipid content. To evaluate the phospholipid preference of...

Accelerating the Translation of Nanomaterials in Biomedicine.

ACS Nano. 2015 Jul 28;9(7):6644-54. doi: 10.1021/acsnano.5b03569. Epub 2015 Jun 26.

Due to their size and tailorable physicochemical properties, nanomaterials are an emerging class of structures utilized in biomedical applications. There are now many prominent examples of nanomaterials being used to improve human health, in areas ranging from imaging and...

Experimental and theoretical investigation of the first-order hyperpolarizability of a class of triarylamine derivatives.

The Journal of chemical physics

Silva DL, Fonseca RD, Vivas MG, Ishow E, Canuto S, Mendonca CR, De Boni L.
PMID: 25681911
J Chem Phys. 2015 Feb 14;142(6):064312. doi: 10.1063/1.4906893.

This paper reports on the static and dynamic first-order hyperpolarizabilities of a class of push-pull octupolar triarylamine derivatives dissolved in toluene. We have combined hyper-Rayleigh scattering experiment and the coupled perturbed Hartree-Fock method implemented at the Density Functional Theory...

Forward bias operation of silicon photonic Mach Zehnder modulators for RF applications.

Optics express

Chao RL, Shi JW, Jain A, Hirokawa T, Khope ASP, Schow C, Bowers JE, Helkey R, Buckwalter JF.
PMID: 29041620
Opt Express. 2017 Sep 18;25(19):23181-23190. doi: 10.1364/OE.25.023181.

In this paper, we demonstrate that forward bias (+0.9V) of a high-speed silicon (Si) optical Mach-Zehnder modulator (MZM) increases the radio-frequency (RF) link gain by 30 dB when compared to reverse bias operation (-8V). RF applications require tunable, narrowband...

A Selected Review of the Mortality Rates of Neonatal Intensive Care Units.

Frontiers in public health

Chow S, Chow R, Popovic M, Lam M, Popovic M, Merrick J, Stashefsky Margalit RN, Lam H, Milakovic M, Chow E, Popovic J.
PMID: 26501049
Front Public Health. 2015 Oct 07;3:225. doi: 10.3389/fpubh.2015.00225. eCollection 2015.

INTRODUCTION: Newborn babies in need of critical medical attention are normally admitted to the neonatal intensive care unit (NICU). These infants tend to be preterm, have low birth weight, and/or have serious medical conditions. Neonatal survival varies, but progress...

Tunable Optical Nanoantennas Incorporating Bowtie Nanoantenna Arrays with Stimuli-Responsive Polymer.

Scientific reports

Wang Q, Liu L, Wang Y, Liu P, Jiang H, Xu Z, Ma Z, Oren S, Chow EK, Lu M, Dong L.
PMID: 26681478
Sci Rep. 2015 Dec 18;5:18567. doi: 10.1038/srep18567.

We report on a temperature-responsive tunable plasmonic device that incorporates coupled bowtie nanoantenna arrays (BNAs) with a submicron-thick, thermosensitive hydrogel coating. The coupled plasmonic nanoparticles provide an intrinsically higher field enhancement than conventional individual nanoparticles. The favorable scaling of...

Reconfigurable nanoantennas using electron-beam manipulation.

Nature communications

Roxworthy BJ, Bhuiya AM, Yu X, Chow EK, Toussaint KC.
PMID: 25020189
Nat Commun. 2014 Jul 14;5:4427. doi: 10.1038/ncomms5427.

Plasmonic nanoantennas have been of increasing interest due to their ability to confine and enhance electric fields in deep sub-wavelength volumes, leading to large near-field optical forces and high refractive index sensitivity. Recently, to enhance the response for sensor...

Clinical vignettes and global health considerations of infertility care in under-resourced patients.

Fertility research and practice

Chow ET, Mahalingaiah S.
PMID: 28620531
Fertil Res Pract. 2016 Mar 02;2:4. doi: 10.1186/s40738-016-0017-6. eCollection 2016.

The ability to receive standard of care for a diagnosis of infertility is a factor of one's financial state and educational level, which are often correlated. Providing infertility care in an under-resourced tertiary care environment provides challenges but also...

Parallel scalability of Hartree-Fock calculations.

The Journal of chemical physics

Chow E, Liu X, Smelyanskiy M, Hammond JR.
PMID: 25770524
J Chem Phys. 2015 Mar 14;142(10):104103. doi: 10.1063/1.4913961.

Quantum chemistry is increasingly performed using large cluster computers consisting of multiple interconnected nodes. For a fixed molecular problem, the efficiency of a calculation usually decreases as more nodes are used, due to the cost of communication between the...
