Ultrastructure of the Infection of Sorghum bicolor by Colletotrichum sublineolum.

Phytopathology

Wharton PS, Julian AM, O'Connell RJ.
PMID: 18944388
Phytopathology. 2001 Feb;91(2):149-58. doi: 10.1094/PHYTO.2001.91.2.149.

ABSTRACT Ultrastructural studies of the infection of susceptible and resistant cultivars of Sorghum bicolor by Colletotrichum sublineolum were conducted. Initial penetration events were the same on both susceptible and resistant cultivars. Germ tubes originating from germinated conidia formed globose,...

Talanta. 1993 May;40(5):765-8. doi: 10.1016/0039-9140(93)80293-z.

A cellulose acetate based optode membrane containing 4-dimethylamino-4'-octylazobenzene as an acid-base indicator is described. Other essential components of the membrane for a fast-responding and durable sensor are diethyl phthalate, triethyleneglycol and potassium tetrakis(4-chlorophenyl)borate. Factors affecting the sensor behaviour are...

Ischemic stroke risk, smoking, and the genetics of inflammation in a biracial population: the stroke prevention in young women study.

Thrombosis journal

Cole JW, Brown DW, Giles WH, Stine OC, O'Connell JR, Mitchell BD, Sorkin JD, Wozniak MA, Stern BJ, Sparks MJ, Dobbins MT, Shoffner LT, Zappala NK, Reinhart LJ, Kittner SJ.
PMID: 18727828
Thromb J. 2008 Aug 26;6:11. doi: 10.1186/1477-9560-6-11.

BACKGROUND: Although cigarette smoking is a well-established risk factor for vascular disease, the genetic mechanisms that link cigarette smoking to an increased incidence of stroke are not well understood. Genetic variations within the genes of the inflammatory pathways are...

Impact of large-angle scattering on diffusively backscattered halos.

Optics letters

Campbell SD, O'Connell AK, Rutherford GH, Grobe R.
PMID: 17392921
Opt Lett. 2007 Mar 01;32(5):560-2. doi: 10.1364/ol.32.000560.

We discuss the impact of large-angle scattering events in highly forward-scattering media on the spatial distribution of the diffusively reflected light. We show that, even for highly forward-scattering media, the reflected light near the incident beam axis is strongly...

Potentiometric flow-injection determination of iodide and iodine.

Talanta

Davey DE, Mulcahy DE, O'Connell GR.
PMID: 18964943
Talanta. 1990 Mar;37(3):313-6. doi: 10.1016/0039-9140(90)80059-o.

A potentiometric flow-injection system is described, in which iodide in the concentration range 10(-6)-10(-1)M may be determined at rates of up to 360 samples/hr at a flow-rate of 17.8 ml/min. Iodine, after on-line reduction to iodide with 0.1M sodium...

Short-term mechanical management of cardiogenic shock.

Current treatment options in cardiovascular medicine

Brown JL, Bogaev RC, O'Connell J.
PMID: 21674171
Curr Treat Options Cardiovasc Med. 2011 Aug;13(4):343-53. doi: 10.1007/s11936-011-0133-x.

OPINION STATEMENT: Cardiogenic shock (CS), a state of cardiac dysfunction that results in systemic hypoperfusion and end-organ dysfunction, is associated with high in-hospital mortality. Various forms of mechanical circulatory support have been used to treat CS. First employed in...

Effect of preoperative shampoos with chlorhexidine or iodophor on emergence of resident scalp flora in neurosurgery.

Infection control and hospital epidemiology

Leclair JM, Winston KR, Sullivan BF, O'Connell JM, Harrington SM, Goldmann DA.
PMID: 19722931
Infect Control Hosp Epidemiol. 1988 Jan;9(1):8-12. doi: 10.1086/645726.

Wound contamination with endogenous bacterial scalp flora plays an important role in the pathogenesis of postoperative neurosurgical infections. To assess the effect of preoperative antiseptic shampoos on the emergence of resident scalp flora during surgery and subsequent wound contamination,...

Measurement of the decay of Fock states in a superconducting quantum circuit.

Physical review letters

Wang H, Hofheinz M, Ansmann M, Bialczak RC, Lucero E, Neeley M, O'Connell AD, Sank D, Wenner J, Cleland AN, Martinis JM.
PMID: 19113602
Phys Rev Lett. 2008 Dec 12;101(24):240401. doi: 10.1103/PhysRevLett.101.240401. Epub 2008 Dec 08.

We demonstrate the controlled generation of Fock states with up to 15 photons in a microwave coplanar waveguide resonator coupled to a superconducting phase qubit. The subsequent decay of the Fock states, due to dissipation, is then monitored by...

Black carbon (BC) from biomass and fossil fuel combustion alters chemical and physical properties of the atmosphere and snow albedo, yet little is known about its emission or deposition histories. Measurements of BC, vanillic acid, and non-sea-salt sulfur in...

Decoherence dynamics of complex photon states in a superconducting circuit.

Physical review letters

Wang H, Hofheinz M, Ansmann M, Bialczak RC, Lucero E, Neeley M, O'Connell AD, Sank D, Weides M, Wenner J, Cleland AN, Martinis JM.
PMID: 20365967

Quantum states inevitably decay with time into a probabilistic mixture of classical states due to their interaction with the environment and measurement instrumentation. We present the first measurement of the decoherence dynamics of complex photon states in a condensed-matter...
