Physiology-Invariant Meal Detection for Type 1 Diabetes.

Diabetes technology & therapeutics

Weimer J, Chen S, Peleckis A, Rickels MR, Lee I.
PMID: 27704875
Diabetes Technol Ther. 2016 Oct;18(10):616-624. doi: 10.1089/dia.2015.0266. Epub 2016 Oct 05.

BACKGROUND: Fully automated artificial pancreas systems require meal detectors to supplement blood glucose level regulation, where false meal detections can cause unnecessary insulin delivery with potentially fatal consequences, and missed detections may cause the patient to experience extreme hyperglycemia....

Variable Temperature Infrared Spectroscopy Studies of Aromatic Acid Adsorbate Effects on Montmorillonite Dehydration.

Applied spectroscopy

Ingram AL, Nickels TM, Maraoulaite DK, White RL.
PMID: 27457265
Appl Spectrosc. 2017 Feb;71(2):238-249. doi: 10.1177/0003702816654155. Epub 2016 Jul 28.

Molecular interactions between benzoic, salicylic, and acetylsalicylic acids and water contained within montmorillonite clay interlayer spaces are characterized by using variable temperature diffuse reflection infrared Fourier transform spectroscopy (VT-DRIFTS). By using sample perturbation and difference spectroscopy, infrared (IR) spectral...

Somatic hybrid plants between Lycopersicon esculentum and Solanum lycopersicoides.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Handley LW, Nickels RL, Cameron MW, Moore PP, Sink KC.
PMID: 24247603
Theor Appl Genet. 1986 Feb;71(5):691-7. doi: 10.1007/BF00263265.

Leaf mesophyll protoplasts of Lycopersicon esculentum (2n=2x=24) were fused with suspension culture-derived protoplasts of Solanum lycopersicoides (2n=2x=24) and intergeneric somatic hybrid plants were regenerated following selective conditions. A two phase selection system was based on the inability of S....

Some predictions of the attached eddy model for a high Reynolds number boundary layer.

Philosophical transactions. Series A, Mathematical, physical, and engineering sciences

Nickels TB, Marusic I, Hafez S, Hutchins N, Chong MS.
PMID: 17244588
Philos Trans A Math Phys Eng Sci. 2007 Mar 15;365(1852):807-22. doi: 10.1098/rsta.2006.1950.

Many flows of practical interest occur at high Reynolds number, at which the flow in most of the boundary layer is turbulent, showing apparently random fluctuations in velocity across a wide range of scales. The range of scales over...

Explicit finite-difference simulation of optical integrated devices on massive parallel computers.

Applied optics

Sterkenburgh T, Michels RM, Dress P, Franke H.
PMID: 18250790
Appl Opt. 1997 Feb 20;36(6):1191-7. doi: 10.1364/ao.36.001191.

An explicit method for the numerical simulation of optical integrated circuits by means of the finite-difference time-domain (FDTD) method is presented. This method, based on an explicit solution of Maxwell's equations, is well established in microwave technology. Although the...

Poly-beta-Hydroxybutyrate Accumulation as a Measure of Unbalanced Growth of the Estuarine Detrital Microbiota.

Applied and environmental microbiology

Nickels JS, King JD, White DC.
PMID: 16345354
Appl Environ Microbiol. 1979 Mar;37(3):459-65. doi: 10.1128/aem.37.3.459-465.1979.

The procaryotic endogenous storage material poly-beta-hydroxybutyrate (PHB) can be induced to accumulate in the estuarine detrital microbiota under conditions which suggest unbalanced growth, such as limitation of a critical factor(s) in the presence of carbon and energy sources. Changes...

Effect of manual brush cleaning on biomass and community structure of microfouling film formed on aluminum and titanium surfaces exposed to rapidly flowing seawater.

Applied and environmental microbiology

Nickels JS, Bobbie RJ, Lott DF, Martz RF, Benson PH, White DC.
PMID: 16345798
Appl Environ Microbiol. 1981 Jun;41(6):1442-53. doi: 10.1128/aem.41.6.1442-1453.1981.

Metals exposed to rapidly flowing seawater are fouled by microbes that increase heat transfer resistance. In this study, results of biochemical test methods quantitatively relating the biomass and community structure of the microfouling film on aluminum and titanium to...

Influence of ions on water diffusion--a neutron scattering study.

The journal of physical chemistry. B

Ben Ishai P, Mamontov E, Nickels JD, Sokolov AP.
PMID: 23713450
J Phys Chem B. 2013 Jun 27;117(25):7724-8. doi: 10.1021/jp4030415. Epub 2013 Jun 12.

Using quasielastic neutron scattering spectroscopy, we measured the averaged translational diffusion of water in solutions of biologically relevant salts, NaCl, a kosmotrope, and KCl, a chaotrope. The analysis revealed the striking difference in the influence of these ions on...

A simple microfluidic platform for rapid and efficient production of the radiotracer [.

Herein, we report the development of a simple, high-throughput and efficient microfluidic system for synthesizing radioactive [18F]fallypride, a PET imaging radiotracer widely used in medical research. The microfluidic chip contains all essential modules required for the synthesis and purification...

Parkinson's disease (PD)-specific neurons, grown in standard 2D cultures, typically only display weak endophenotypes. The cultivation of PD patient-specific neurons, derived from induced pluripotent stem cells carrying the LRRK2-G2019S mutation, is optimized in 3D microfluidics. The automated image analysis...
