The evolutionary pattern of mutations in glioblastoma reveals therapy-mediated selection.

Oncotarget

Muscat AM, Wong NC, Drummond KJ, Algar EM, Khasraw M, Verhaak R, Field K, Rosenthal MA, Ashley DM.
PMID: 29487696
Oncotarget. 2017 Dec 15;9(8):7844-7858. doi: 10.18632/oncotarget.23541. eCollection 2018 Jan 30.

Glioblastoma presents as a heterogeneous disease with poor prognosis despite the use of multimodal therapy. Analysis of genomic DNA changes between initial diagnosis and recurrence in response to standard treatment protocols would enhance understanding of disease progression and better...

Ammonia photodissociation promoted by Si(100).

The journal of physical chemistry. A

Finstad CC, Muscat AJ.
PMID: 24802663
J Phys Chem A. 2014 Jun 05;118(22):3880-90. doi: 10.1021/jp408543e. Epub 2014 May 20.

Using in situ X-ray photoelectron spectroscopy measurements after reaction, we show that hydrogen-terminated Si(100) perturbs the bonding of physisorbed NH3 enabling a photochemical decomposition pathway at wavelengths different from those characteristic of either the molecule in the gas phase...

Association Studies of HFE C282Y and H63D Variants with Oral Cancer Risk and Iron Homeostasis Among Whites and Blacks.

Cancers

Jones NR, Ashmore JH, Lee SY, Richie JP, Lazarus P, Muscat JE.
PMID: 26690219
Cancers (Basel). 2015 Dec 09;7(4):2386-96. doi: 10.3390/cancers7040898.

BACKGROUND: Polymorphisms in the hemochromatosis (HFE) gene are associated with excessive iron absorption from the diet, and pro-oxidant effects of iron accumulation are thought to be a risk factor for several types of cancer.METHODS: The C282Y (rs1800562) and H63D...

Dissociation of the effects of amphetamine and quinpirole on dopamine release in the nucleus accumbens following behavioural sensitization: an ex vivo voltammetric study.

Behavioural pharmacology

Muscat R, Patel J, Trout SJ, Wieczorek W, Kruk ZL.
PMID: 11224210
Behav Pharmacol. 1993;4(4):411-418.

Behavioural sensitization to the locomotor stimulant effect of (+)-amphetamine or quinpirole was induced in rats by intermittent drug administration. Once established, endogenous dopamine release (DA) was measured in slices containing nucleus accumbens using fast cyclic voltammetry. DA release induced...

Time-dependent and schedule-dependent effects of dopamine receptor blockade.

Behavioural pharmacology

Willner P, Phillips G, Sampson D, Muscat R.
PMID: 11175400
Behav Pharmacol. 1989;1(2):169-176.

Rats were trained on one of two multiple random-interval schedules of reinforcement, which contained both ascending and descending reinforcement density sequences. The design of the schedules made it possible to determine whether performance changes in a particular component depended...

The orphan Rev-erb nuclear receptors: a link between metabolism, circadian rhythm and inflammation?.

Nuclear receptor signaling

Ramakrishnan SN, Muscat GE.
PMID: 16741567
Nucl Recept Signal. 2006;4:e009. doi: 10.1621/nrs.04009. Epub 2006 Apr 28.

Nuclear hormone receptors (NRs) function as ligand dependent DNA binding proteins that translate physiological/nutritional signals into gene regulation. Dysfunctional NR signaling leads to many disorders in reproduction, inflammation, and metabolism. The opportunity to identify novel regulatory pathways in the...

Capillary affinity gel electrophoresis for combined size- and sequence-dependent separation of oligonucleotides.

Analytical chemistry

Muscate A, Natt F, Paulus A, Ehrat M.
PMID: 21644736
Anal Chem. 1998 Apr 01;70(7):1419-24. doi: 10.1021/ac971057f.

An interesting new approach to capillary affinity gel electrophoresis (CAGE) has been developed for the selective capture and separation of homopolymer and heteropolymer oligonucleotides. The combination of selectivity of bioaffinity recognition and high-resolution power of capillary gel electrophoresis allows...

[Prophylactic cranial irradiation in patients with extensive disease caused by small-cell lung cancer responsive to chemotherapy: fewer symptomatic brain metastases and improved survival].

Nederlands tijdschrift voor geneeskunde

Slotman BJ, Faivre-Finn C, Kramer GW, Rankin E, Snee M, Hatton M, Postmus PE, Collette L, Musat E, Senan S.
PMID: 18549175
Ned Tijdschr Geneeskd. 2008 Apr 26;152(17):1000-4.

OBJECTIVE: To determine the effect of prophylactic cranial irradiation (PCI) in patients with extensive-disease small-cell lung cancer (ED-SCLC) who responded to chemotherapy.DESIGN: Randomised, controlled clinical trial; phase III study (EORTC nr 08993-22993; www.clinicaltrials.gov, nr NCT00016211).METHOD: Patients aged 18-75 years...

Treatment planning study of the 3D dosimetric differences between Co-60 and Ir-192 sources in high dose rate (HDR) brachytherapy for cervix cancer.

Journal of contemporary brachytherapy

Palmer A, Hayman O, Muscat S.
PMID: 23346140
J Contemp Brachytherapy. 2012 Mar;4(1):52-9. doi: 10.5114/jcb.2012.27952. Epub 2012 Mar 30.

PURPOSE: To evaluate whether Co-60 is equivalent to Ir-192 for HDR cervical brachytherapy, through 3D-DVH dose comparisons in standard and optimised plans. Previous studies have only considered 2D dosimetry, point dose comparisons or identical loading. Typical treatment times and...

P53 protein overexpression in lung adenocarcinomas in non-smokers.

Oncology reports

Muscat J, Citron M, Wang C, White A, Lazarus P.
PMID: 21590150
Oncol Rep. 1997 Jul-Aug;4(4):825-7. doi: 10.3892/or.4.4.825.

Greater than 55% of all lung cancers contain mutations in the p53 tumor suppressor gene, and the frequency of p53 mutations has been directly correlated with the use of tobacco and the smoking of cigarettes. To determine if environmental...

Effects of amphetamine and pimozide on reinforcement and motor parameters in variable-interval performance.

Journal of psychopharmacology (Oxford, England)

Willner P, Towell A, Muscat R.

The effects of amphetamine and pimozide were studied in rats performing on variable-interval (VI) schedules of reinforcement. In experiment 1, a five-component multiple VI schedule was used; in experiments 2 and 3, two VI schedules were presented on alternate...
