Grant success

30 January 2017:

CNBP researchers at Macquarie University – Research Fellow Lindsay Parker (pictured left) and A/Prof Andrei Zvyagin have been successful as Chief Investigators on a $100,000 Macquarie University Research Infrastructure Block Grant.

The grant will support a research assistant (Anna Guller, CNBP PhD candidate) to help build capacity in and use Macquarie University’s bioreactor equipment towards the production and maintenance of live bioartificial tissues for sustainable scientific use.

The CNBP researchers will be collaborating with the University’s Faculty of Medicine to use these artificial biotissues in order to assess nanoparticle detection capabilities/depths in complex tissue structures.

Lead CI on the grant is Professor Qian Yi in the Faculty of Medicine.

CNBP takes centre stage at Biofocus Conference

15 December 2016:

CNBP researchers were at the forefront of this year’s Biofocus Conference held at Macquarie University, 15 December 2016.

Early career Centre researchers Annemarie Nadort, Lindsay Parker and Nima Sayyadi sat on the conference organising committee, Centre Deputy Director Ewa Goldys (pictured) opened proceedings while CNBP Chief Investigator Prof Andrew Abell (from the University of Adelaide) delivered an extremely well received plenary talk titled, “Defining biomolecular structure and function in solution and on surfaces: new therapeutics and biological probes.”

The annual conference provides a platform for the multidisciplinary community at Macquarie University to present and communicate research, discuss research outcomes and facilitate interdisciplinary collaborations spanning the fields of of biomedical sciences, biomedical engineering, physics, chemistry and medicine.

Feedback from attendees at this year’s event was extremely positive with plenty of formal and informal scientific discussion taking place between sessions.

Relevance of methamphetamine’s to psychosis

lindsay_parker-low-rez-web128 August 2016:

CNBP researcher Lindsay Parker (pictured left) and CNBP Associate Investigator Jennifer Cornish have coauthored the following paper, examining the relevance of methamphetamine’s to psychosis.

Journal: Neuropharmacology

Publication title: GABAergic mRNA Expression is Differentially Expressed Across the Prelimbic and Orbitofrontal Cortices of Rats Sensitized to Methamphetamine: Relevance to Psychosis.

Authors: Travis A. Wearne, Lindsay M. Parker, Jane L. Franklin, Ann K. Goodchild, Jennifer L. Cornish.

Abstract: Psychotic disorders, such as schizophrenia, are characterized by prevalent and persistent executive deficits that are believed to be the result of dysfunctional inhibitory gamma-aminobutyric acid (GABA) processing of the prefrontal cortex (PFC). Methamphetamine (METH) is a commonly used psychostimulant that can induce psychotic and cognitive symptoms that are indistinguishable to schizophrenia, suggesting that METH-induced psychosis may have a similar GABAergic profile of the PFC. As the PFC consists of multiple subregions, the aim of the current study was to investigate changes to GABAergic mRNA expression in the prelimbic (PRL) and orbitofrontal (OFC) cortices of the PFC in rats sensitized to repeated METH administration. Male Sprague Dawley rats underwent daily METH or saline injections for 7 days. Following 14 days of withdrawal, rats were challenged with acute METH administration, RNA was isolated from the PRL and OFC and quantitative PCR was used to compare the relative expression of GABA enzymes, transporters, metabolites and receptor subunits. GAD67, GAD65, GAT1, GAT3, VGAT and GABAT mRNA expression were upregulated in the PRL. Ionotropic GABAA receptor subunits α1, α3, α5 and β2 were specifically upregulated in the OFC. These findings suggest that alterations to GABAergic mRNA expression following sensitization to METH are biologically dissociated between the OFC and PRL, suggesting that GABAergic gene expression is significantly altered following chronic METH exposure in a brain-region and GABA-specific manner. These changes may lead to profound consequences on central inhibitory mechanisms of localized regions of the PFC and may underpin common behavioral phenotypes seen across psychotic disorders.

The paper is available online.

 

International Conference on New Diamond and Nano Carbons

28 May-1 June 2017:

CNBP Research Fellows at Macquarie University, Dr Lindsay Parker (pictured) and Dr Nicole Cordina will attend the 11th International Conference on New Diamond and Nano Carbons 2017 to be held in Cairns, Australia May 28 – June 1.

The conference spans wide research topics from fundamental physical and chemical concepts to applied technologically driven applications with carbon based materials. Those include, but not limited to single crystal diamond, nanodiamonds, carbon nanotubes, graphene and other carbon nanostructures.

Dr Parker has been selected for an oral presentation for her work titled: “Applications of fluorescent nanodiamonds in cellular molecular tracing”.

Dr Cordina has been selected for a poster presentation for her work titled: “Targeting fluorescent nanodiamonds to E-selectin for the detection of inflammation”.

CNBP at US-Australia Technical Exchange meeting

Visit to McMeen Elementary School in Denver

lindsay_parker-low-rez-web112 February 2016:

Fitting in a half day of outreach at McMeen Elementary School in Denver, Colorado, was a highlight for CNBP Research Fellow Lindsay Parker.

Spending time with a class of Year 5 students and their teacher, Lindsay led discussion about what scientists do, how research is conducted and answered a large number of science related queries.

Students were provided with the CNBP educational activity resource sheet and also given an overview of light based research currently being undertaken at the nanoscale.

“Spending time with kids and encouraging their interest in science and technology is a real buzz,” says Lindsay. “These kids were extremely inquisitive which is great.”

Summer scholarship students at Macquarie

lindsay_parker-low-rez-web110 February 2016:

Lindsay Parker, CNBP Research Fellow, supervised undergraduate student Tereza Lois-Palumbo and Masters student Ashish Shrestha during their 5 week summer scholarship program at Macquarie University.

Tereza and Ashish researched gene changes in multiple cell lines after exposure to LPS inflammation. They learned skills in cell culture, sample staining, microscopy, data analysis and data presentations during their short program.

Ashish will continue to be mentored by Lindsay throughout the year on CNBP related research projects related to ISH gene testing.
