Personalized Medication Response Prediction for Attention-Deficit Hyperactivity Disorder: Learning in the Model Space vs. Learning in the Data Space.

Frontiers in physiology

Wong HK, Tiffin PA, Chappell MJ, Nichols TE, Welsh PR, Doyle OM, Lopez-Kolkovska BC, Inglis SK, Coghill D, Shen Y, Tiño P.
PMID: 28443027
Front Physiol. 2017 Apr 11;8:199. doi: 10.3389/fphys.2017.00199. eCollection 2017.

Attention-Deficit Hyperactive Disorder (ADHD) is one of the most common mental health disorders amongst school-aged children with an estimated prevalence of 5% in the global population (American Psychiatric Association, 2013). Stimulants, particularly methylphenidate (MPH), are the first-line option in...

Is tool-making knowledge robust over time and across problems?.

Frontiers in psychology

Beck SR, Cutting N, Apperly IA, Demery Z, Iliffe L, Rishi S, Chappell J.
PMID: 25538650
Front Psychol. 2014 Dec 04;5:1395. doi: 10.3389/fpsyg.2014.01395. eCollection 2014.

In three studies, we explored the retention and transfer of tool-making knowledge, learnt from an adult demonstration, to other temporal and task contexts. All studies used a variation of a task in which children had to make a hook...

A matched observational study of canine survival with primary intraocular melanocytic neoplasia.

Veterinary ophthalmology

Giuliano EA, Chappell R, Fischer B, Dubielzig RR.
PMID: 11397263
Vet Ophthalmol. 1999;2(3):185-190. doi: 10.1046/j.1463-5224.1999.00080.x.

A retrospective histopathologic study was performed to evaluate the effect of primary intraocular melanocytic neoplasia on canine survival. Tumor size, location within the globe, extent of infiltration, and mitotic index were analyzed for their potential to predict survival. A...

The roles of the sun and the landscape in pigeon homing.

The Journal of experimental biology

Wallraff HG, Chappell J, Guilford T.
PMID: 10409483
J Exp Biol. 1999;202:2121-2126.

It seems reasonable to assume that pigeons use visual features in the landscape for orientation when they are homing over familiar terrain. Experimental evidence to prove or disprove this possibility is, however, difficult to obtain. Here, we link the...

Quadrupole ion traps and trap arrays: geometry, material, scale, performance.

European journal of mass spectrometry (Chichester, England)

Ouyang Z, Gao L, Fico M, Chappell WJ, Noll RJ, Cooks RG.
PMID: 17878533
Eur J Mass Spectrom (Chichester). 2007;13(1):13-8. doi: 10.1255/ejms.832.

Quadrupole ion traps are reviewed, emphasizing recent developments, especially the investigation of new geometries, guided by multiple particle simulations such as the ITSIM program. These geometries include linear ion traps (LITs) and the simplified rectilinear ion trap (RIT). Various...

Reprint of "Pharmacokinetic modelling of the anti-malarial drug artesunate and its active metabolite dihydroartemisinin".

Computer methods and programs in biomedicine

Hall AJ, Chappell MJ, Aston JA, Ward SA.
PMID: 24457047
Comput Methods Programs Biomed. 2014 May;114(3):e14-28. doi: 10.1016/j.cmpb.2013.12.001. Epub 2014 Jan 20.

A four compartment mechanistic mathematical model is developed for the pharmacokinetics of the commonly used anti-malarial drug artesunate and its principle metabolite dihydroartemisinin following oral administration of artesunate. The model is structurally unidentifiable unless additional constraints are imposed. Combinations...

Recent Advances in Understanding the Reversal of Gene Silencing During X Chromosome Reactivation.

Frontiers in cell and developmental biology

Talon I, Janiszewski A, Chappell J, Vanheer L, Pasque V.
PMID: 31552244
Front Cell Dev Biol. 2019 Sep 03;7:169. doi: 10.3389/fcell.2019.00169. eCollection 2019.

Dosage compensation between XX female and XY male cells is achieved by a process known as X chromosome inactivation (XCI) in mammals. XCI is initiated early during development in female cells and is subsequently stably maintained in most somatic...
