Modeling of Zymomonas mobilis central metabolism for novel metabolic engineering strategies.

Frontiers in microbiology

Kalnenieks U, Pentjuss A, Rutkis R, Stalidzans E, Fell DA.
PMID: 24550906
Front Microbiol. 2014 Feb 05;5:42. doi: 10.3389/fmicb.2014.00042. eCollection 2014.

Mathematical modeling of metabolism is essential for rational metabolic engineering. The present work focuses on several types of modeling approach to quantitative understanding of central metabolic network and energetics in the bioethanol-producing bacterium Zymomonas mobilis. Combined use of Flux...

Manifold sensitivity improvement of swelling-based sensors.

Physical chemistry chemical physics : PCCP

AlQahtani H, Alduraibi M, Richardson T, Grell M.
PMID: 22422298
Phys Chem Chem Phys. 2012 Apr 28;14(16):5558-60. doi: 10.1039/c2cp00003b. Epub 2012 Mar 16.

The sensitivity of swelling-based gold core-organic shell nanoparticle vapor sensors is improved manifold by cooling sensors below ambient temperature. This is due to the reduced volatility of the analyte. Sensitivity to a particular analyte scales with temperature like that...

Bell MA, Lee CE.
PMID: 10370267
Trends Ecol Evol. 1999 Jul;14(7):284-8. doi: 10.1016/S0169-5347(99)01596-7.

Transitions from marine to freshwater habitats constitute dramatic shifts between 'adaptive zones' that have initiated the radiation and speciation of many taxa. As recently as 10?000 years ago, deglaciation resulted in marine fauna being trapped in freshwater lakes. In...

Increasing the flux in metabolic pathways: A metabolic control analysis perspective .

Biotechnology and bioengineering

Fell DA.
PMID: 10191380
Biotechnol Bioeng. 1998 Apr 05;58(2):121-4. doi: 10.1002/(sici)1097-0290(19980420)58:2/3<121::aid-bit2>3.0.co;2-n.

The problems of engineering increased flux in metabolic pathways are analyzed in terms of the understanding provided by metabolic control analysis. Over-expression of a single enzyme is unlikely to be effective unless it is known to have a high...

Interpersonal disturbance in OCD and its place in the professional consultation.

Irish journal of psychological medicine

O'Connor J, Fuller R, Fell M.

Ir J Psychol Med. 2004 Sep;21(3):104-109. doi: 10.1017/S079096670000848X.

People with obsessive-compulsive disorder (OCD) typically experience their relationships with others with a high level of trepidation and bring their anxieties into their work with professionals. We have written this paper to describe experiences of working with people with...
