SU-E-T-583: Feasibility of Constraining Dose to the Nausea Center (area Postrema and Dorsal Vagal Complex) in IMRT Treatment Planning of the Head and Neck.

Medical physics

Fontenla S, Wang T, Lee N, McCann P, Young R, Mechalakos J.
PMID: 28517096
Med Phys. 2012 Jun;39(6):3840. doi: 10.1118/1.4735672.

PURPOSE: Nausea and vomiting have been known to occur in patients undergoing external beam radiation treatments for head&neck cancers. We sought to determine the feasibility of limiting the dose delivered to the nausea center, area postrema (AP) and dorsal...

The influence of rotator cuff pathology on functional outcome in total shoulder replacement.

International journal of shoulder surgery

Ahearn N, McCann PA, Tasker A, Sarangi PP.
PMID: 24403759
Int J Shoulder Surg. 2013 Oct;7(4):127-31. doi: 10.4103/0973-6042.123509.

INTRODUCTION: Total shoulder replacement (TSR) is a reliable treatment for glenohumeral osteoarthritis. In addition to proper component orientation, successful arthroplasty requires accurate restoration of soft tissues forces around the joint to maximize function. We hypothesized that pathological changes within...

Copper-Catalyzed Aerobic Oxidations of Organic Molecules: Pathways for Two-Electron Oxidation with a Four-Electron Oxidant and a One-Electron Redox-Active Catalyst.

Accounts of chemical research

McCann SD, Stahl SS.
PMID: 26020118
Acc Chem Res. 2015 Jun 16;48(6):1756-66. doi: 10.1021/acs.accounts.5b00060. Epub 2015 May 28.

Selective oxidation reactions have extraordinary value in organic chemistry, ranging from the conversion of petrochemical feedstocks into industrial chemicals and polymer precursors to the introduction of heteroatom functional groups into pharmaceutical and agrochemical intermediates. Molecular oxygen (O2) would be...

Second-Order Biomimicry: In Situ Oxidative Self-Processing Converts Copper(I)/Diamine Precursor into a Highly Active Aerobic Oxidation Catalyst.

ACS central science

Real-time diode laser measurements of vapor-phase benzene.

Analytical chemistry

Jeffers JD, Roller CB, Namjou K, Evans MA, McSpadden L, Grego J, McCann PJ.
PMID: 14719893
Anal Chem. 2004 Jan 15;76(2):424-32. doi: 10.1021/ac0345392.

An absorption spectrometer equipped with a IV-VI semiconductor tunable mid-IR diode laser was used to make sensitive measurements of benzene (C(6)H(6)) gas in the 5.1-microm spectral range. Wavelength modulation coupled with second-harmonic detection achieved accurate real-time quantification of benzene...

Dissociation of the ground state vinoxy radical and its photolytic precursor chloroacetaldehyde: electronic nonadiabaticity and the suppression of the H+ketene channel.

The Journal of chemical physics

Miller JL, McCunn LR, Krisch MJ, Butler LJ, Shu J.
PMID: 15260734
J Chem Phys. 2004 Jul 22;121(4):1830-8. doi: 10.1063/1.1765653.

This work is a study of the competition between the two unimolecular reaction channels available to the vinoxy radical (CH(2)CHO), C-H fission to form H+ketene, and isomerization to the acetyl radical (CH(3)CO) followed by C-C fission to form CH(3)...

Ornithine decarboxylase, polyamines, and pyrrolizidine alkaloids in senecio and crotalaria.

Plant physiology

Birecka H, Birecki M, Cohen EJ, Bitonti AJ, McCann PP.
PMID: 16665870
Plant Physiol. 1988 Jan;86(1):224-30. doi: 10.1104/pp.86.1.224.

When tested for ornithine and arginine decarboxylases, pyrrolizidine alkaloid-bearing Senecio riddellii, S. longilobus (Compositae), and Crotalaria retusa (Leguminosae) plants exhibited only ornithine decarboxylase activity. This contrasts with previous studies of four species of pyrrolizidine alkaloid-bearing Heliotropium (Boraginaceae) in which...

Assaying ornithine and arginine decarboxylases in some plant species.

Plant physiology

Birecka H, Bitonti AJ, McCann PP.
PMID: 16664441
Plant Physiol. 1985 Oct;79(2):509-14. doi: 10.1104/pp.79.2.509.

A release of (14)CO(2) not related to ornithine decarboxylase activity was found in crude leaf extracts from Lycopersicon esculentum, Avena sativa, and especially from the pyrrolizidine alkaloid-bearing Heliotropium angiospermum when incubated with [1-(14)C]- or [U-(14)C]ornithine. The total (14)CO(2) produced...

Response of photosynthesis and cellular antioxidants to ozone in populus leaves.

Plant physiology

Gupta AS, Alscher RG, McCune D.
PMID: 16668235
Plant Physiol. 1991 Jun;96(2):650-5. doi: 10.1104/pp.96.2.650.

Atmospheric ozone causes formation of various highly reactive intermediates (e.g. peroxyl and superoxide radicals, H(2)O(2), etc.) in plant tissues. A plant's productivity in environments with ozone may be related to its ability to scavenge the free radicals formed. The...

A study of the unimolecular dissociation of the 2-buten-2-yl radical via the 193 nm photodissociation of 2-chloro-2-butene.

The journal of physical chemistry. A

McCunn LR, Krisch MJ, Liu Y, Butler LJ, Shu J.

J Phys Chem A. 2005 Jul 28;109(29):6430-9. doi: 10.1021/jp050970e.

This work investigates the unimolecular dissociation of the 2-buten-2-yl radical. This radical has three potentially competing reaction pathways: C-C fission to form CH3 + propyne, C-H fission to form H + 1,2-butadiene, and C-H fission to produce H +...

Rapid gel-like latex film formation through controlled ionic coacervation of latex polymer particles containing strong cationic and protonated weak acid functionalities.
