Investigating the causal effect of cannabis use on cognitive function with a quasi-experimental co-twin design

quasi-experimental designs

Ross JM, Ellingson JM, Rhee SH, Hewitt JK.
GSID: wM37gJZClRYJ
JM Ross, JM Ellingson, SH Rhee, JK Hewitt… - Drug and alcohol …, 2020 - Elsevier

… We used a quasi-experimental co-twin control design to test the effect of cannabis on intelligence and EFs. While others have examined intelligence using this design, we are the first to examine multiple EF factors using an extensive and...

Ionic charge transport between blockages: Sodium cation conduction in freshly excised bulk brain tissue.

AIP advances

Emin D, Akhtari M, Ellingson BM, Mathern GW.
PMID: 26339528
AIP Adv. 2015 Aug 11;5(8):087133. doi: 10.1063/1.4928652. eCollection 2015 Aug.

We analyze the transient-dc and frequency-dependent electrical conductivities between blocking electrodes. We extend this analysis to measurements of ions' transport in freshly excised bulk samples of human brain tissue whose complex cellular structure produces blockages. The associated ionic charge-carrier...

Recent advances in synthetic biosafety.

Simon AJ, Ellington AD.
PMID: 27635235
F1000Res. 2016 Aug 31;5. doi: 10.12688/f1000research.8365.1. eCollection 2016.

Synthetically engineered organisms hold promise for a broad range of medical, environmental, and industrial applications. Organisms can potentially be designed, for example, for the inexpensive and environmentally benign synthesis of pharmaceuticals and industrial chemicals, for the cleanup of environmental...

One-step tumor detection from dynamic morphology tracking on aptamer-grafted surfaces.

Technology

Mahmood MA, Hasan MR, Khan UJ, Allen PB, Kim YT, Ellington AD, Iqbal SM.
PMID: 26753172
Technology (Singap World Sci). 2015 Dec;3(4):194-200. doi: 10.1142/S2339547815500089. Epub 2015 Nov 16.

In this paper, we report a one-step tumor cell detection approach based on the dynamic morphological behavior tracking of cancer cells on a ligand modified surface. Every cell on the surface was tracked in real time for several minutes...

Nonworksite Interventions to Reduce Sedentary Behavior among Adults: A Systematic Review.

Translational journal of the American College of Sports Medicine

Thraen-Borowski KM, Ellingson LD, Meyer JD, Cadmus-Bertram L.
PMID: 28993817
Transl J Am Coll Sports Med. 2017 Jun 15;2(12):68-78. doi: 10.1249/TJX.0000000000000036.

PURPOSE: Sedentary behavior has been identified as a major health risk. While interventions to reduce time spent sedentary have become increasingly prevalent, the vast majority of this work in adults has been focused on workplace sedentary behavior, and often...

Near infrared to ultraviolet optical properties of bulk single crystal and nanocrystal thin film iron pyrite.

Nanotechnology

Subedi I, Bhandari KP, Ellingson RJ, Podraza NJ.
PMID: 27285310
Nanotechnology. 2016 Jul 22;27(29):295702. doi: 10.1088/0957-4484/27/29/295702. Epub 2016 Jun 10.

We report optical properties of iron pyrite (FeS2) determined from ex situ spectroscopic ellipsometry measurements made on both a commercially available bulk single crystal and nanocrystalline thin film over a spectral range of 0.735-5.887 eV. The complex dielectric function,...

Speciation in Vanadium Bioinorganic Systems. 2. An NMR, ESR, and Potentiometric Study of the Aqueous H(+)-Vanadate-Maltol System.

Inorganic chemistry

Elvingson K, González Baró A, Pettersson L.
PMID: 11666543
Inorg Chem. 1996 May 22;35(11):3388-3393. doi: 10.1021/ic951195s.

A systematic study of the physiologically interesting vanadium-maltol (V-MaH) system has been performed in 0.150 M Na(Cl) at 25 degrees C, using NMR, ESR, and potentiometric techniques. Complexation occurs within a wide pH range, from around 1 up to...

Heart rate variability analysis of effect of nicotine using periodograms.

Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual Conference

Thong T, Yung IO, P Zajdel DP, Ellingson RM, McNames J, Aboy M, Oken BS.
PMID: 17271668
Conf Proc IEEE Eng Med Biol Soc. 2004;2006:294-7. doi: 10.1109/IEMBS.2004.1403150.

Heart rate variability (HRV) is frequently used to measure autonomic nervous system (ANS) activity. However, little is known about the mechanism underlying pharmacologically induced changes in HRV. Previous research has shown that nicotine exposure stimulates the ANS, mediating a...

Temperature dependence of carbon-13 kinetic isotope effects of importance to global climate change.

Journal of the American Chemical Society

Lin H, Zhao Y, Ellingson BA, Pu J, Truhlar DG.
PMID: 15740100
J Am Chem Soc. 2005 Mar 09;127(9):2830-1. doi: 10.1021/ja0434026.

We report here a theoretical study of the 13C kinetic isotope effect (KIE) and its temperature dependence for the reaction OH + CH4 --> H2O + CH3, the major sink of atmospheric methane in the troposphere. The KIE values...

Embodied knowledge: writing researchers' bodies into qualitative health research.

Qualitative health research

Ellingson LL.
PMID: 16394216
Qual Health Res. 2006 Feb;16(2):298-310. doi: 10.1177/1049732305281944.

After more than a decade of postpositivist health care research and an increase in narrative writing practices, social scientific, qualitative health research remains largely disembodied. The erasure of researchers' bodies from conventional accounts of research obscures the complexities of...
