Intra-species Genomic and Physiological Variability Impact Stress Resistance in Strains of Probiotic Potential.

Frontiers in microbiology

Arnold JW, Simpson JB, Roach J, Kwintkiewicz J, Azcarate-Peril MA.
PMID: 29515537
Front Microbiol. 2018 Feb 20;9:242. doi: 10.3389/fmicb.2018.00242. eCollection 2018.

Large-scale microbiome studies have established that most of the diversity contained in the gastrointestinal tract is represented at the strain level; however, exhaustive genomic and physiological characterization of human isolates is still lacking. With increased use of probiotics as...

Zookeys. 2013 Feb 18;(270):1-20. doi: 10.3897/zookeys.270.3736. Print 2013.

Two new species of Conopea (Say 1822) are described from the Gulf of Guinea: Conopea saotomensis sp. n.and Conopea fidelis sp. n. These two new species were collected from the historically isolated volcanic islands of São Tomé and Príncipe....

OS043. Identification and validation of novel markers for the predictionof pre-eclampsia.

Pregnancy hypertension

Myers J, Tuytten R, Thomas G, McCowan L, Dekker G, Baker P, Poston L, Kenny L, Simpson N, North R.
PMID: 26105257
Pregnancy Hypertens. 2012 Jul;2(3):200. doi: 10.1016/j.preghy.2012.04.044. Epub 2012 Jun 13.

INTRODUCTION: Currently no test accurately predicts pre-eclampsia (PE) in a healthy nulliparous population. Unbiased protein biomarker discovery has the potential to identify novel markers but multimarker panels are required to achieve clinically relevant prediction of PE. To this purpose,...

Ultrafast infrared spectroscopy reveals water-mediated coherent dynamics in an enzyme active site.

Chemical science

Adamczyk K, Simpson N, Greetham GM, Gumiero A, Walsh MA, Towrie M, Parker AW, Hunt NT.
PMID: 28936306
Chem Sci. 2015 Jan 01;6(1):505-516. doi: 10.1039/c4sc02752c. Epub 2014 Oct 22.

Understanding the impact of fast dynamics upon the chemical processes occurring within the active sites of proteins and enzymes is a key challenge that continues to attract significant interest, though direct experimental insight in the solution phase remains sparse....

An unusually compact retrotransposon in maize.

Plant molecular biology

Johns MA, Babcock MS, Fuerstenberg SM, Fuerstenberg SI, Freeling M, Simpson RB.
PMID: 24271196
Plant Mol Biol. 1989 Jun;12(6):633-42. doi: 10.1007/BF00044154.

Unlike any other known plant transposon, the maize transposable element Bs1 is similar to the retrotransposons previously described in yeast and Drosophila. Bs1 is bounded by 302 bp identical long terminal repeats (LTRs), and it contains open reading frames...

Clavicular Nonunion and Malunion: Evaluation and Surgical Management.

The Journal of the American Academy of Orthopaedic Surgeons

Simpson NS, Jupiter JB.
PMID: 10790675
J Am Acad Orthop Surg. 1996 Jan;4(1):1-8. doi: 10.5435/00124635-199601000-00001.

Nonunions and malunions of the clavicle are uncommon but can be disabling. Pain, limitation of shoulder mobility, or local compression of the brachial plexus can produce profound functional impairment. Nonunions usually are associated with more severe fractures, open injuries,...

The cost-effectiveness of neonatal screening for cystic fibrosis: an analysis of alternative scenarios using a decision model.

Cost effectiveness and resource allocation : C/E

Simpson N, Anderson R, Sassi F, Pitman A, Lewis P, Tu K, Lannin H.
PMID: 16091139
Cost Eff Resour Alloc. 2005 Aug 09;3:8. doi: 10.1186/1478-7547-3-8.

BACKGROUND: The use of neonatal screening for cystic fibrosis is widely debated in the United Kingdom and elsewhere, but the evidence available to inform policy is limited. This paper explores the cost-effectiveness of adding screening for cystic fibrosis to...

Transfer of orbital angular momentum from a stressed fiber-optic waveguide to a light beam.

Applied optics

McGloin D, Simpson NB, Padgett MJ.
PMID: 18268608
Appl Opt. 1998 Jan 20;37(3):469-72. doi: 10.1364/ao.37.000469.

A stressed fiber-optic waveguide is used to impart orbital angular momentum to a Hermite-Gaussian (HG(10)) laser mode. The transmitted beam has an annular intensity profile and a well-defined azimuthal phase dependence. We confirm the phase structure of the beam...

Mechanical equivalence of spin and orbital angular momentum of light: an optical spanner.

Optics letters

Simpson NB, Dholakia K, Allen L, Padgett MJ.
PMID: 18183100
Opt Lett. 1997 Jan 01;22(1):52-4. doi: 10.1364/ol.22.000052.

We use a Laguerre-Gaussian laser mode within an optical tweezers arrangement to demonstrate the transfer of the orbital angular momentum of a laser mode to a trapped particle. The particle is optically confined in three dimensions and can be...

Molecular genetic evidence for interspecific hybridization among endemic Hispaniolan Bursera (Burseraceae).

American journal of botany

Weeks A, Simpson BB.
PMID: 21653453
Am J Bot. 2004 Jun;91(6):976-84. doi: 10.3732/ajb.91.6.976.

Historically, genetic introgression among species as well as hybrid origins for species of the diploid tree genus Bursera (Burseraceae) have been proposed based on the supposition that individuals morphologically intermediate between sympatric "parent" species must be derived from hybridization....

Characterization of 14 microsatellite loci in a tropical palm, Attalea phalerata (Arecaceae).

American journal of botany

Choo J, Ishak H, Simpson B, Mueller U, Juenger T.
PMID: 21616808
