Sci-Thur PM: YIS - 04: Forcing lateral electron disequilibrium to spare lung tissue: A novel technique for SBRT of small lung tumours.

Medical physics

Disher B, Hajdok G, Gaede S, Battista JJ.
PMID: 28516557
Med Phys. 2012 Jul;39(7):4622. doi: 10.1118/1.4740101.

Stereotactic body radiation therapy(SBRT), a technique that uses tightly conformed Megavoltage(MV) x-ray fields, improves local control of lung cancer. However, small MV x-ray fields can cause lateral electron disequilibrium(LED), which reduces the dose within lung. These effects are difficult...

Image-guided adaptive radiation therapy (IGART): Radiobiological and dose escalation considerations for localized carcinoma of the prostate.

Medical physics

Song W, Schaly B, Bauman G, Battista J, Van Dyk J.
PMID: 28493587
Med Phys. 2005 Jul;32(7):2193-2203. doi: 10.1118/1.1935775.

The goal of this work was to evaluate the efficacy of various image-guided adaptive radiation therapy (IGART) techniques to deliver and escalate dose to the prostate in the presence of geometric uncertainties. Five prostate patients with 15-16 treatment CT...

Cost-Consequence Analysis of Nitisinone for Treatment of Tyrosinemia Type I.

The Canadian journal of hospital pharmacy

Simoncelli M, Samson J, Bussières JF, Lacroix J, Dorais M, Battista R, Perreault S.
PMID: 26157182
Can J Hosp Pharm. 2015 May-Jun;68(3):210-7.

BACKGROUND: Tyrosinemia type I is a rare but severe genetic metabolic disorder. Nitisinone combined with a diet low in tyrosine and phenylalanine became first-line therapy in 1994.OBJECTIVES: To estimate the direct medical costs of health care services related to...

First-principles investigation of electrochemical properties of gold nanoparticles.

Nanotechnology

Batista RJ, Mazzoni MS, Chacham H.
PMID: 20057038
Nanotechnology. 2010 Feb 10;21(6):065705. doi: 10.1088/0957-4484/21/6/065705. Epub 2010 Jan 08.

A first-principles formalism is employed to investigate the effects of size and structure on the electronic and electrochemical properties of Au nanoparticles with diameters between 0.8 and 2.0 nm. We find that the behavior of the ionization potentials (IPs)...

A comparison between the 2010 and 2005 basic life support guidelines during simulated hypogravity and microgravity.

Extreme physiology & medicine

Russomano T, Baers JH, Velho R, Cardoso RB, Ashcroft A, Rehnberg L, Gehrke RD, Dias MK, Baptista RR.
PMID: 23849595
Extrem Physiol Med. 2013 Apr 01;2(1):11. doi: 10.1186/2046-7648-2-11.

BACKGROUND: Current 2010 terrestrial (1Gz) CPR guidelines have been advocated by space agencies for hypogravity and microgravity environments, but may not be feasible. The aims of this study were to (1) evaluate rescuer performance over 1.5 min of external...

Dynamic negative compressibility of few-layer graphene, h-BN, and MoS2.

Nano letters

Barboza AP, Chacham H, Oliveira CK, Fernandes TF, Ferreira EH, Archanjo BS, Batista RJ, de Oliveira AB, Neves BR.
PMID: 22468807
Nano Lett. 2012 May 09;12(5):2313-7. doi: 10.1021/nl300183e. Epub 2012 Apr 10.

We report a novel mechanical response of few-layer graphene, h-BN, and MoS(2) to the simultaneous compression and shear by an atomic force microscope (AFM) tip. The response is characterized by the vertical expansion of these two-dimensional (2D) layered materials...

Erratum: Medical physics staffing for radiation oncology: a decade of experience in Ontario, Canada.

Journal of applied clinical medical physics

Universal deformation pathways and flexural hardening of nanoscale 2D-material standing folds.

Nanotechnology

Chacham H, Barboza APM, de Oliveira AB, de Oliveira CK, Batista RJC, Neves BRA.
PMID: 29300171
Nanotechnology. 2018 Mar 02;29(9):095704. doi: 10.1088/1361-6528/aaa51e.

In the present work, we use atomic force microscopy nanomanipulation of 2D-material standing folds to investigate their mechanical deformation. Using graphene, h-BN and talc nanoscale wrinkles as testbeds, universal force-strain pathways are clearly uncovered and well-accounted for by an...
