Tissue Level Compartmentation of (R)-Amygdalin and Amygdalin Hydrolase Prevents Large-Scale Cyanogenesis in Undamaged Prunus Seeds.

Plant physiology

Poulton JE, Li CP.
PMID: 12232058
Plant Physiol. 1994 Jan;104(1):29-35. doi: 10.1104/pp.104.1.29.

Plum (Prunus domestica) seeds, which contain the cyanogenic diglucoside (R)-amygdalin and lesser amounts of the corresponding monoglucoside (R)-prunasin, release the respiratory toxin HCN upon tissue disruption. Amygdalin hydrolase (AH) and prunasin hydrolase (PH), two specific [beta]-glucosidases responsible for hydrolysis...

Structural and functional aspects of the diabetic foot.

Clinical biomechanics (Bristol, Avon)

Morag E, Pammer S, Boulton A, Young M, Deffner K, Cavanagh P.
PMID: 11415708
Clin Biomech (Bristol, Avon). 1997 Apr;12(3):S9-S10. doi: 10.1016/s0268-0033(97)88319-2.

INTRODUCTION:: It has been well documented that, on average, patients with diabetes mellitus (DM) have higher plantar pressures than persons without DM, and there are several hypotheses why this may be -- many focused on the role of peripheral...

Catabolism of Cyanogenic Glycosides by Purified Vicianin Hydrolase from Squirrel's Foot Fern (Davallia Trichomanoides Blume).

Plant physiology

Lizotte PA, Poulton JE.
PMID: 16665903
Plant Physiol. 1988 Feb;86(2):322-4. doi: 10.1104/pp.86.2.322.

Vicianin hydrolase, which catalyzes the hydrolysis of vicianin (K(m), 4.9 millimolar) to (R)-mandelonitrile and vicianose at an optimum pH of 5.5, was extensively purified from the young fronds and fiddleheads of the squirrel's foot fern (Davallia trichomanoides Blume) using...

Cyanogenesis in plants.

Plant physiology

Poulton JE.
PMID: 16667728
Plant Physiol. 1990 Oct;94(2):401-5. doi: 10.1104/pp.94.2.401.

Several thousand plant species, including many economically important food plants, synthesize cyanogenic glycosides and cyanolipids. Upon tissue disruption, these natural products are hydrolyzed liberating the respiratory poison hydrogen cyanide. This phenomenon of cyanogenesis accounts for numerous cases of acute...

Tissue and Subcellular Localization of Enzymes Catabolizing (R)-Amygdalin in Mature Prunus serotina Seeds.

Plant physiology

Swain E, Li CP, Poulton JE.
PMID: 16652960
Plant Physiol. 1992 Sep;100(1):291-300. doi: 10.1104/pp.100.1.291.

In black cherry (Prunus serotina Ehrh.) homogenates, (R)-amygdalin is catabolized to HCN, benzaldehyde, and d-glucose by the sequential action of amygdalin hydrolase, prunasin hydrolase, and mandelonitrile lyase. The tissue and subcellular localizations of these enzymes were determined within intact...

Design and operation of a very large ring laser gyroscope.

Applied optics

Rowe CH, Schreiber UK, Cooper SJ, King BT, Poulton M, Stedman GE.
PMID: 18319821
Appl Opt. 1999 Apr 20;38(12):2516-23. doi: 10.1364/ao.38.002516.

The design and initial operation of a vertical square He-Ne ring laser G0 with a perimeter of 14 m is discussed. This builds on earlier demonstrations of the feasibility of large ring lasers (perimeter approximately 4 m) for single-mode...

A survey of contact lens wear among diabetic patients in the United Kingdom.

Contact lens & anterior eye : the journal of the British Contact Lens Association

Veys J, Efron N, Boulton A.
PMID: 16303365
Cont Lens Anterior Eye. 1997;20:S27-33. doi: 10.1016/s1367-0484(97)80026-4.

A survey of attitudes to the fitting of contact lenses to diabetic patients was sent to 1122 optometric, ophthalmological and dispensing members of the British Contact Lens Association; 418 completed questionnaires were analysed. Sixty-two per cent of practitioners considered...

Assessing the capacity of the health services research community in Australia and New Zealand.

Australia and New Zealand health policy

Pirkis J, Goldfeld S, Peacock S, Dodson S, Haas M, Cumming J, Hall J, Boulton A.
PMID: 15755322
Aust New Zealand Health Policy. 2005 Mar 08;2(1):4. doi: 10.1186/1743-8462-2-4.

BACKGROUND: In order to profile the health services research community in Australia and New Zealand and describe its capacity, a web-based survey was administered to members of the Health Services Research Association of Australia and New Zealand (HSRAANZ) and...

Non-reciprocal transmission and Schmitt trigger operation in strongly modulated asymmetric WBGs.

Optics express

Fujii M, Maitra A, Poulton C, Leuthold J, Freude W.
PMID: 19532169
Opt Express. 2006 Dec 25;14(26):12782-93. doi: 10.1364/oe.14.012782.

We investigate numerically a non-reciprocal switching behavior in strongly modulated waveguide Bragg gratings (WBGs) having a longitudinally asymmetric stopband configuration. The minimum power predicted for a stable switching operation is found to be approximately 77 mW for a realistic...

Desensitization of superfused isolated ovine anterior pituitary cells to human corticotropin-releasing factor.

Journal of neuroendocrinology

Thomson M, Chan EC, Falconer J, Madsen G, Geraghty S, Curryert N, Boulton J, Smith R.
PMID: 19210381
J Neuroendocrinol. 1990 Apr 01;2(2):181-7. doi: 10.1111/j.1365-2826.1990.tb00848.x.

Abstract We have employed an in vitro system to study the time-course of beta-endorphin (beta-EP) immunoreactivity release from anterior pituitary cells stimulated with corticotropin-releasing factor (CRF) and whether exposure to CRF desensitizes the cells to subsequent stimulation. Ovine anterior...
