Enhanced electrochemical stability of polyaniline in ionic liquids
P. C. Innis,T. Nguyen,J. Mazurkiewicz,G. G. Wallace,D. MacFarlane 한국물리학회 2004 Current Applied Physics Vol.4 No.2-4
The electrochemical performance of polyaniline thin films on platinum electrode substrates has been investigated using cyclic voltammetry in two aprotic ionic liquid electrolyte systems, 1-butyl-3-methyl imidazolium hexafluorophosphate (BMI PF6 ) or 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfon)imide (EMI TFSI). Enhanced redox stability of the polyaniline was observed in both electrolyte systems. Initial redox cycles in both ILs exhibited increasing current responses, over the first 10–20 cycles, which was attributed to the electrochemically induced ion exchange processes occurring within polyaniline film. Extended cycling after the redoping process was observed to result in a stable and reversible electrochemistry.

Polymerisation and characterisation of conducting polyaniline nanoparticle dispersions
S. E. Moulton,P. C. Innis,Kane-Maguire,O. Ngamna,G. G. Wallace 한국물리학회 2004 Current Applied Physics Vol.4 No.2-4
Micellar emulsion chemical polymerisation of polyaniline (PANI) using dodecylbenzenesulfonic acid (DBSA) as the micelle anddopant was performed at 20.C. It was necessary to use a ratio of 1:1:1 for aniline, oxidant (ammonium persulfate APS) and DBSAto produce the PANIÆDBSA in the emeraldine salt (ES) form in large quantities (40 g). The resulting polymer was a nanodispersionwith spherical particles 10±2 nm in diameter and an electrical conductivity of 15±3 Scm. 1 as determined by transmission electronmicroscopy (TEM) and the four-point probe method, respectively. UVvis spectral characterisation showed the nanodispersion tobe highly doped. Complete deprotonation of the polymer to the emeraldine base form using 0.5 M NaOH was only possible upondilution to approximately 0.05% w/v polymer. Reduction of the polymer to leucoemeraldine using phenylhydrazine was relativelyslow; however, oxidation to pernigraniline in 0.25 M APS occurred instantaneously.

Putting Function into Fashion: Organic Conducting Polymer Fibres and Textiles
Wallace, G.G.,Campbell, T.E.,Innis, P.C. The Korean Fiber Society 2007 Fibers and polymers Vol.8 No.2
Textiles have traditionally been employed over the centuries with great utility in areas as diverse as fashion through to technical textiles. In all these instances the textile itself has been a structural element that once fabricated has limited utility beyond the intended structural and aesthetic application. In recent years there has been a shift towards the incorporation of electronic systems into textile structures. The new paradigm for textiles is the development of systems that not only provide the more traditional aspects of textiles but expands upon this to provide a unique capability to transmit and store information and energy. More importantly these next generation materials will be capable of responding to external stimuli, modifying features of the textile in a direct response to its working environment. A potential route to truly functional electronic textiles is through the application of conducting polymers.

Propofol decreases in vivo binding of 11C-PBR28 to translocator protein (18 kDa) in the human brain.
Hines, Christina S,Fujita, Masahiro,Zoghbi, Sami S,Kim, Jin Su,Quezado, Zenaide,Herscovitch, Peter,Miao, Ning,Ferraris Araneta, Maria D,Morse, Cheryl,Pike, Victor W,Labovsky, Julia,Innis, Robert B Society of Nuclear Medicine 2013 The Journal of nuclear medicine Vol.54 No.1
<P>The PET radioligand (11)C-PBR28 targets translocator protein (18 kDa) (TSPO) and is a potential marker of neuroimmune activation in vivo. Although several patient populations have been studied using (11)C-PBR28, no investigators have studied cognitively impaired patients who would require anesthesia for the PET procedure, nor have any reports investigated the effects that anesthesia may have on radioligand uptake. The purpose of this study was to determine whether the anesthetic propofol alters brain uptake of (11)C-PBR28 in healthy subjects.</P>

In Brazil, the trajectories of institutionalization of environmental education policies were marked by efforts of fostering social mobilization around environmental issues. This paper aims to discuss the challenges of constructing participatory democracy in Brazil by trajectories of institutionalization of environmental education policies. The text presents the environmental education main legislation and its national system focusing on the public structure for environmental education in the State of Rio de Janeiro (in southeast Brazil), from 2007 to 2013. The work also overviews the policies developed by the State Secretary of the Environment in non-formal and formal education and present the methodology of the Elos da Cidadania (Links of Citizenship) Program, which was developed in public schools with the purpose of promoting teacher and student's participation in environment councils and commissions. Finally, it discusses the challenges of institutionalizing critical environmental education pari passu with the challenges of constructing democracy in Brazil.

Nanomaterial for Skeletal Muscle Regeneration
Jeong Gun-Jae,Castels Hannah,Kang Innie,Aliya Berna,Jang Young Charles 한국조직공학과 재생의학회 2022 조직공학과 재생의학 Vol.19 No.2
Skeletal muscle has an innate regenerative capacity to restore their structure and function following acute damages and injuries. However, in congenital muscular dystrophies, large volumetric muscle loss, cachexia, or aging, the declined regenerative capacity of skeletal muscle results in muscle wasting and functional impairment. Recent studies indicate that muscle mass and function are closely correlated with morbidity and mortality due to the large volume and location of skeletal muscle. However, the options for treating neuromuscular disorders are limited. Biomedical engineering strategies such as nanotechnologies have been implemented to address this issue. In this review, we focus on recent studies leveraging nano-sized materials for regeneration of skeletal muscle. We look at skeletal muscle pathologies and describe various proof-of-concept and pre-clinical studies that have used nanomaterials, with a focus on how nano-sized materials can be used for skeletal muscle regeneration depending on material dimensionality. Depending on the dimensionality of nano-sized materials, their application have been changed because of their different physical and biochemical properties. Nanomaterials have been spotlighted as a great candidate for addressing the unmet needs of regenerative medicine. Nanomaterials could be applied to several types of tissues and diseases along with the unique characteristics of nanomaterials. However, when confined to muscle tissue, the targets of nanomaterial applications are limited and can be extended in future research.

We present an unusual case of advanced ovarian carcinoma with postoperative complications of ischemia and perforation of therectum as a result of tumor embolism. The interval progression from ischemia to infarction of the rectum was captured in repeatedsigmoidoscopies. A brief discussion on tumor embolism and management of this case is also included.
