Risk of thyroid cancer in Ukrainian cleanup workers following the Chornobyl accident.

European journal of epidemiology

Gudzenko N, Mabuchi K, Brenner AV, Little MP, Hatch M, Drozdovitch V, Vij V, Chumak V, Bakhanova E, Trotsyuk N, Kryuchkov V, Golovanov I, Bazyka D, Cahoon EK.
PMID: 34897585
Eur J Epidemiol. 2021 Dec 12; doi: 10.1007/s10654-021-00822-9. Epub 2021 Dec 12.

Although much is known about the radiation-related risk of thyroid cancer in those exposed at young ages, less is known about the risk due to adult exposure, particularly in men. We aimed to examine the association between thyroid radiation...

Encoding abrupt and uniform dopant profiles in vapor-liquid-solid nanowires by suppressing the reservoir effect of the liquid catalyst.

ACS nano

Christesen JD, Pinion CW, Zhang X, McBride JR, Cahoon JF.
PMID: 25363730
ACS Nano. 2014 Nov 25;8(11):11790-8. doi: 10.1021/nn505404y. Epub 2014 Nov 05.

Semiconductor nanowires (NWs) are often synthesized by the vapor-liquid-solid (VLS) mechanism, a process in which a liquid droplet-supplied with precursors in the vapor phase-catalyzes the growth of a solid, crystalline NW. By changing the supply of precursors, the NW...

Metabolic Evidence for the Involvement of a [delta]4-Palmitoyl-Acyl Carrier Protein Desaturase in Petroselinic Acid Synthesis in Coriander Endosperm and Transgenic Tobacco Cells.

Plant physiology

Cahoon EB, Ohlrogge JB.
PMID: 12232129
Plant Physiol. 1994 Mar;104(3):827-837. doi: 10.1104/pp.104.3.827.

We have previously demonstrated that the double bond of petroselinic acid (18:1[delta]6cis) in coriander (Coriandrum sativum L.) seed results from the activity of a 36-kD desaturase that is structurally related to the [delta]9-stearoyl-acyl carrier protein (ACP) desaturase (E.B. Cahoon,...

DESATURATION AND RELATED MODIFICATIONS OF FATTY ACIDS1.

Annual review of plant physiology and plant molecular biology

Shanklin J, Cahoon EB.
PMID: 15012248
Annu Rev Plant Physiol Plant Mol Biol. 1998 Jun;49:611-641. doi: 10.1146/annurev.arplant.49.1.611.

Desaturation of a fatty acid first involves the enzymatic removal of a hydrogen from a methylene group in an acyl chain, a highly energy-demanding step that requires an activated oxygen intermediate. Two types of desaturases have been identified, one...

Ratcheting quasi-ballistic electrons in silicon geometric diodes at room temperature.

Science (New York, N.Y.)

Custer JP, Low JD, Hill DJ, Teitsworth TS, Christesen JD, McKinney CJ, McBride JR, Brooke MA, Warren SC, Cahoon JF.
PMID: 32273466
Science. 2020 Apr 10;368(6487):177-180. doi: 10.1126/science.aay8663.

Ratcheting effects play an important role in systems ranging from mechanical socket wrenches to biological motor proteins. The underlying principle is to convert a fluctuating, unbiased force into unidirectional motion. Here, we report the ratcheting of electrons at room...

The combination of Moore's law and Dennard's scaling rules have constituted the fundamental guidelines for the silicon-based semiconductor industry for decades. Furthermore, the enormous growth of global data volume has pushed the demand for complex and densely packed devices....

Culturally-adapted Family Intervention (CaFI) for African-Caribbeans diagnosed with schizophrenia and their families: a feasibility study protocol of implementation and acceptability.

Pilot and feasibility studies

Edge D, Degnan A, Cotterill S, Berry K, Drake R, Baker J, Barrowclough C, Hughes-Morley A, Grey P, Bhugra D, Cahoon P, Tarrier N, Lewis S, Abel K.
PMID: 27965857
Pilot Feasibility Stud. 2016 Aug 03;2:39. doi: 10.1186/s40814-016-0070-2. eCollection 2016.

BACKGROUND: African-Caribbeans in the UK have the highest schizophrenia incidence and greatest inequity in access to mental health services of all ethnic groups. The National Institute for Health and Care Excellence (NICE) highlights this crisis in care and urgent...

Interplay of Surface Recombination and Diode Geometry for the Performance of Axial p-i-n Nanowire Solar Cells.

ACS nano

Hill DJ, Teitsworth TS, Ritchie ET, Atkin JM, Cahoon JF.
PMID: 30235417
ACS Nano. 2018 Oct 23;12(10):10554-10563. doi: 10.1021/acsnano.8b06577. Epub 2018 Sep 25.

Nanowires (NWs) with axial p-i-n junctions have been widely explored as microscopic diodes for optoelectronic and solar energy applications, and their performance is strongly influenced by charge recombination at the surface. We delineate how the photovoltaic performance of these...

Barrierless Switching between a Liquid and Superheated Solid Catalyst during Nanowire Growth.

The journal of physical chemistry letters

Pinion CW, Hill DJ, Christesen JD, McBride JR, Cahoon JF.
PMID: 27717285
J Phys Chem Lett. 2016 Oct 20;7(20):4236-4242. doi: 10.1021/acs.jpclett.6b01918. Epub 2016 Oct 12.

Knowledge of nucleation and growth mechanisms is essential for the synthesis of nanomaterials, such as semiconductor nanowires, with shapes and compositions precisely engineered for technological applications. Nanowires are conventionally grown by the seemingly well-understood vapor-liquid-solid mechanism, which uses a...

3D Plant cell architecture of Arabidopsis thaliana (Brassicaceae) using focused ion beam-scanning electron microscopy.
