LittledidIrealise,whenIinitiatedtheHighImpactResearch(HIR)programme
for the university in February 2010, that it would grow into such a giant
programme. It is just like the proverbial mustard seed which grew into a
humongoustree!
InAugustthisyear,theMinistryofHigherEducationMalaysia(MoHE)injected
RM590millionintotheUMHIRprogrammefollowingtheCabinet’sdecision
thatUMshouldbegiventhechancetobreakintothetop100worldranked
universitiesin2015.Thatwehaveearnedthetrustofthegovernmentinsuch
ashorttimeisquiteamiracleinitself.However,ittookalotofpersuasion
onourparttojustifytheirfaith.FromAugusttoDecember2011,MoHEhas
promisedtoreleaseRM40milliontoUMontheundertakingthattheuniversity
topthiswithanotherRM40millionfrominternalfunds.
ThefollowingfacultiessucceededingettingfundingthroughMoHE:Medicine,
Dentistry,Science,EngineeringandComputerScience.Inaddition,8top-down
research projects and one special project to purchase high-end equipment
for central facilities were approved under the Chancellory HIR programme.
A dedicated HIR Building is being readied to provide a more conducive
environmentforsomeoftheflagshipprojectsfundedunderMoHE.

Title: Antimicrobial Peptides against Multidrug Resistant
Burkholderia pseudomallei and Mechanisms of Action
Principal Investigator : Professor Dr. Jamuna Vadivelu
Faculty : Department of Medical Microbiology, Faculty of Medicine
Burkholderia pseudomallei, the causative agent of melioidosis, are widely
foundinthesoilandsurfacewaterthroughoutthetropicsespeciallyinSouth
EastAsiaandNorthernAustralia.Currently,therearenovaccinesavailable
for the treatment of Melioidosis. Antibiotic therapy is also problematic
becauseB. pseudomalleiisintrinsicallyresistanttomanyantibiotics,resulting
in high mortality rates of 19% in Australia and even 50% in Thailand. The
spread of antibiotic-resistant bacterial infections has stimulated the need
for development of new antibiotics. Antimicrobial peptides (AMPs) possess
potentbroad-spectrumbactericidalactivitiesandareregardedaspromising
therapeutic alternatives in the fight against resistant microorganisms.
Moreover, these peptides may also affect inflammation, immune activation
andwoundhealing.
Objectives
Methodology Outcome
To identify and evaluate the
efficacy of suitable synthetic or
naturalantimicrobialpeptidesand
peptides that will be designed
based on the functional groups
of effective antibiotics against
B. pseudomallei as an alternate
therapeutic modality. Following
screening of suitable peptides
that are effective against B.
pseudomallei, the mechanism of
action of these peptides will also
bedetermined
B. pseudomallei isolates will be
obtained from Universiti Malaya
Medical Centre (UMMC) and
International Islamic University
(UIA), Pahang and the sensitivity
of these isolates towards
commonly used antibiotics will
be determined using the MIC
E-test, disk diffusion and micro
broth dilution methods. Resistant
strainswillbeidentifiedandtested
usingidentifiedsyntheticornatural
antimicrobialpeptides.Thetoxicity
of the selected peptides will
also be evaluated using time kill
studies and cytotoxicity studies.
The mechanism of membrane
damage caused by the selected
peptides will be determined using
membranepermeabilisationassay,
determination of phosphate and
potassium ion efflux followed by
electron microscopy analysis.
The antimicrobial action of these
peptides will also be analysed
using whole genome transcription
profilingtoenableidentificationof

Title: Is the Leading Edge of Neurulation an Asymmetrical
Lamellipodia-Like Structure Emanating From the Surface
Ectoderm and Whether This Mirrors the Human Spina
Bifida Condition?
Principal Investigator : Dr. Noraishah Mydin Abdul-Aziz
Faculty : Department of Parasitology, Faculty of Medicine
PreliminarystudiesconductedbyAbdul-Azizetal.showedthatperturbation
of Eph/ephrin signalling produced an enlarged posterior neuropore, multiple
apoptoticcells,andfilopodial-likeprotrusionsfromtheleftsidedneuralfold

observed emanating from the left non-neural ectoderm. The driving force
of adhesion and fusion distinctly expresses EphA2 as it branches into the

Found In Parenterally Infected HIV Patients
Principal Investigator : Dr. Tee Kok Keng
Faculty : Centre of Excellence for Research in AIDS (CERIA), Faculty of
Medicine
In Malaysia, a total of 78,784 human immunodeficiency virus type 1 (HIV1) cases have been reported while 9,586 people have died of AIDS-related
illnessesasofJune2007.Ofthese,morethan75%wereinfectedparenterally

hepatitisCvirus(HCV)andthenewlydiscoveredhumanparvovirus4(PARV4).
ChronicHCVinfectionhasbeenstronglyassociatedwithlivercancer.Asof
December 2008, it was reported in Malaysia that among 5,804 drug users
attending the Methadone Maintenance Treatment program in hospitals and
primaryhealthcaresettings,28%areinfectedwithHCV(unpublisheddata).
Among HIV-positive injecting drug users (IDUs) however the prevalence of
HCV is exceptionally high at 100%, underlining the severity of HIV/HCV
co-infection among this high-risk group. Biologically, HCV is classified into
seven genotypes that further diverged into over 80 distinct subtypes. Such

Title: Evaluation of Mesenchymal Stem Cells Isolated
From Various Sources As An In Vitro Models For Drug
Screening and Toxicity Testing
Principal Investigator : Dr. Mariam Abdullah
Faculty : Department of Conservative Dentistry, Faculty of Dentistry
Summary of Research Proposal
Despite spiraling R&D costs in discovering new drugs for therapeutic use,
90%ofleadcandidatesidentifiedbycurrentinvitrosystemsfailtobecome
drugs. The currently used in vivo tests are time consuming, expensive and
require a large number of animals (Hofer et al., 2004). Therefore, there is a
direneedtoestablishnewerinvitrodevelopmenttoxicityassaystoreduce
thenumberoftestanimalsandexpenseswithoutcompromisingthesafety

lastfewyearsthefieldofpluripotentstemcellshaswitnessedastrongshift
ofparadigmfromregenerativemedicinetowardsdrugscreening.Embryonic
stem cell (ESC) has emerged as an attractive model in the pharmaceutical
industry for in vitro screening due to their enormous potential in facilitating
drugscreeningprograms(Paletal.,2009).However,scarcityofthesource
andtheinvasiveproceduresrequiredtoisolateandculturethesecellshave
limited their use. In this scenario, mesenchymal stem cells are considered
to be an appealing source for stem cells as they are noncontroversial,
readilyaccessible,hasalargedonorpoolandnoriskofdiscomfortforthe
donor. Here we propose stem cells as a novel in vitro platform for toxicity
assessmentofvariouscompounds,teratogens,smallmolecules,biomaterials
and drugs. These novel in vitro models can predict the effect of toxins at
various phases of cell cycle as well as stages of growth, development and
differentiation. Moreover, these stem cell-based models would also permit

The ROI will be determined so as
it corresponds with SVS chosen
in MRS. The assessment of the
lesions in MR images will be
done by a radiologist. He/she
will be blinded to the eventual
histology grade of the tumor.
The assessment will also include
calculation of the percentage

fromvariouslocalitiesinMalaysia,
Indonesia and Japan based
on morphological features and
reproductive organs. Further
confirmation of the identity
of crustose brown algae and
examination of their taxonomic
positionatthefamilialandordinal
level can be accomplished by
exploiting the use of molecular
markers of chloroplast origin
(rbcL) and mitochondrial-based
marker (cox1). In addition to that,
we are keen to determine the
species number of Mesospora,
commonly found in warmer
waters, in this region and to
distinguish Mesospora schmidtii

Brown algal crusts will be
collected from several localities in
Malaysia, Indonesia and Japan.
These rocks are first air-dried
and later desiccated in silica
gel and maintained at ambient
temperature. For morphological
observations, light microscopical
examinations will be done on
squash preparations which are
then mounted in corn syrup on
glass slides. As for the molecular
studies, totalgenomicDNAwillbe
extractedbygrinding30-40mgof

encoded marker (cox1 and etc.).
The resulting PCR products will
then undergo purification, cycle
sequencing and finally DNA
sequencing. The DNA sequences
will then be analyzed and
phylogenetic trees will be inferred
using maximum parsimony (MP),

Title: Exploring the Cardiovascular Mechanism for the
Potential use of Quercetin as adjuvant to Metformin/

Principal Investigator : Dr. Dharmani Devi a/p Murugan
Faculty: Department of Pharmacology, Faculty of Medicine
Diabetesisaglobalhealthconcernthatrequiresseriouseffortbyallnations
towards arresting its scourge. Study by Wild et al., (2004) indicated that
the prevalence of diabetes amongst all age-groups worldwide is estimated
to increase from 2.8% in 2000 to 4.4% in 2030. Diabetes is characterized
by chronic hyperglycaemia, and over time, results in serious harm to many
body systems, including the blood vasculatures. Hyperglycaemia leads to
oxidative stress which is seen as increased production of reactive oxygen
spesies (ROS) and ultimately leads to development of endothelial Recent

Title: Circulating microRNAs as Novel Biomarkers for
Early Detection of Atherosclerosis
Principal Investigator : Professor Dr. Wan Azman Wan Ahmad
The importance of microRNA (miRNA) in diseases has been recognized
overtheyearswithmountingevidenceoftheirexistenceandcontributionto
diseases. miRNA expression profiles between normal and diseased tissues
have identified signatures that enable disease classification, progression,
diagnosis and prognosis. The presence of miRNAs, termed circulating
miRNAsinbodyfluidsincludingserum,plasma,urine,salivaandbreastmilk
haspromptedvariousinvestigationsintotheirusefordiagnosisandprognosis
of various cancers and cardiovascular diseases. While these miRNAs may
beusefulinthediagnosisoffullblowncardiovasculardiseases(CVD),there
arenoreportsoncirculatingmiRNAthatcanbeamarkertopredictpatients
who will develop accelerated or premature atherosclerotic diseases and
also to identify circulating miRNAs that can be used to detect vulnerable
atherosclerotic plaques which can predispose patient to acute coronary
syndrome.Identficationofprematureatherosclerotic-associatedmiRNAswill
be useful in early detection and treatment of atherosclerotic diseases and

Title: Analysis of Endocrine Disrupting Chemicals in Food
and Environment (SUCXeS)
Principal Investigator : Professor Dr. Mustafa Ali Mohd
Faculty : Department of Pharmacology, Faculty of Medicine
Evidence suggests that environmental exposure to some anthropogenic
chemicals may result in disruption of endocrine systems in human and
wildlifepopulations.Someofthewellknownexamplesarethefeminization
offishbynonylphenolorestradiol,andmuscalinizationofsnailbyorgano-tin
compounds.Endocrinedisruptersareexogenoushormone-likecompounds
which mimic natural hormones by occupying the binding site of hormone
receptor. The other type of disruption mechanism includes antagonism of
hormonesorinhibitionofthesynthesisandmetabolismofhormones.Many
ofknownendocrinedisruptersareenvironmentalestrogensanditisforthis
reason that feminization is often observed in the environment. In addition
to estrogen-like compounds, some other endocrine disrupter is known to
showanti-estrogenicactivity,orthyroidhormoneactivity. Disruptionofthe
endocrinesystemwillleadtothefailureofreproductionandsubsequentlyto
thelossofbiologicalspecies. Our research program on endocrine disruptors started several years ago
by the formation of the University of Malaya Endocrine Disrupters research
group. The aim is to explore the possible adverse effects suspected due
to environmental chemicals on the reproductive and other high-integrated
biologicalsystemsinhumansandanimals.
Nationwide monitoring has been done in 2000 and 2001 in Malaysia to
establish a baseline and a comprehensive database in Malaysia. The

Title: Targeted Delivery of Antineoplastic Photoactive
Compounds and Peptides
Principal Investigator : Professor Dr. Chung Lip Yong
Faculty : Department of Pharmacy, Faculty of Medicine
Cancer is the second major life threatening disease in the world and
the common cancer treatment modalities such as chemotherapy and
radiotherapy often inflict adverse effects to patients. New photosensitizer
basedphotodynamictherapy(PDT)andanticancerpeptidebasedtreatments
havebeenproposedtoprovidebettertreatmentoutcomewithlesseradverse

peptidesthataffectefficientdrugdeliveryoftenlimittheirdevelopmentand
useinclinicalsettings.
ToovercomethechallengesofdeliveryofPDTandpeptidedrugsinvivo,the
drugs may be modified by conjugating or entrapping them to water soluble
biocompatiblepolymers.Modificationofthephotosensitizer’spharmacokinetic
properties via polymer-drug conjugation approach may increase the water/
blood solubility, reduce in vivo random dissemination and non-specific
cytotoxicity, and promote the targeting of photosensitizer to the tumour via
enhanced-permeability-retentioneffect.Foranticancerpeptides,encapsulation
by biopolymers may improve their protection against degradation by low
gastric pH and enzymes, providing a controlled release of the entrapped
macromolecules and hence increase the bioavailability and pharmacological
efficacyoftheanticancerpeptideswhengivenviatheoralroute.

Objectives
Methodology The objective of the study is to
explore the possibility of applying
polymer-drug conjugation and
a polymer based intestinal
sustained drug delivery approach
to improve the antitumour
efficacy of photoactive drugs
and anticancer peptides. This
is based on the hypothesis that
conjugation of photoactive drugs
onto a suitable polymeric carrier
such as polyglutamic acid, and
inclusion of anticancer peptides
ontoasuitableintestinalsustained
drug delivery system may help to
improve the bioavailability, in vivo

in vivo antitumour efficacy of

Objectives
Aspertheresearchproblems,we
havesetourinitialobjectivetocarry
on an investigation on a suitable
characterization method to make
realisticextrapolations.Alongwith
this, we will explore mathematical
and statistical methods to have
an accurate measurement of the
defects which are subject as the
adverse outcome of negative

NBTI degradation. Finally we
will investigate the right stress
conditions in such a way that
the defect responsible for NBTI
degradation is only accelerated
and not to trigger other defect
generationmodes
Methodology In order to characterize NBTI
initially we are supposed to go
through a thorough literature

consist of theoretical modeling,
simulation, device and circuitlevel mismatch. Along with these
the physics of dynamic NBTI
will be investigated, in order to
have a transparent idea on AC

Title: Production of Hydrogen by Hydrolysis of Biomass
Principal Investigator : Dr. Jaya Narayan Sahu
Hydrolysis, gasification, pyrolysis, and catalytic pyrolysis of biomass are
identifiedasthepromisingandcompetitiveroutesforproducingrenewable
hydrogen, although other bioenergy technologies have been developed.
Biomasswastehydrolyzedintohighvalue-addedproductsisapracticaland
effectiveway.Currentindustrialhydrolysismethodsofbiomasswasteinclude
chemical (acid, alkali or catalytic) hydrolysis and enzymatic hydrolysis. But
the chemical hydrolysis needs violent reaction conditions and often brings
seriouspollutionoftheenvironment.Enzymatichydrolysisisexpensive,and
withlongproductioncycle.Therefore,theidentificationanddevelopmentof
a new environment-friendly method to overcome the shortcomings of the
chemicalandenzymatichydrolysisisparticularlyimportant.
Objectives
Most of biomass waste is easily
hydrolyzed in super- or subcritical water, which is structurally
different from normal liquid water,
and possesses some marvelous
properties: first, it behaves like
non-polar organic solvent (similar
withacetone)
Thus it can substitute for some
of organic solvents, and become
a clean medium for chemical
reactions; second, it has density
fluctuation,
low
dielectric
properties,andmolecularclusters,
thus it can become an effective
medium for energy and mass
transfer; third, its ionic product
(H+andOH-)isthousandsoftimes
24/05/2012 9:44:55
higher than normal water, thus it
can take on a powerful catalysis
based on acid and alkali at the
same time, and it also can be a

Title: Hybrid Solar Energy Research for Rural Electrification
Principal Investigator: Associate Professor Dr. Hew Wooi Ping.
About 93.1% of Malaysian households has access to electricity which is

access to electricity mostly due to inaccessible communication and the
access recorded in Sabah is 85% while in Sarawak it is recorded at 90%
(RegionalReport,UNDP2007).ThataccesstoelectricityisrelatedtosocioeconomicdevelopmentshasbeenindicatedbystudiesinMalaysia(Regional

Objectives
Methodology Outcome
Introducing a new hydrogen
refueling algorithm based on
renewable energy process by
considering
the
electrolysis
analysis and renewable energy as
afundamentalmodel.
WhensolarpowerfromthePVarray
is unavailable or insufficient (e.g.,
duetocloudcover,etc.),electricity
from the grid is used for the
electrolysis process. The system,
when running exclusively on solar
energy,couldproduceabout2,000
liters (approximately at 30 bar)
of gaseous hydrogen per year
which is enough to fuel hydrogen
or fuel cell vehicle. By using both
solar power and electricity from
the grid, the station’s production
capabilityisexpectedtobe24,000
liters per year, whilst cars could
befueledattherateof5litersper
minute. Hydrogen fuel (in the gas
form) would be dispensed to the
hydrogen vehicle (hybrid or fuel
cell) using a unique fast-fill and
multi-bankcascadesystem
A test rig of hydrogen refueling
station that can be used to study
hydrogenrefuelingandproduction
systemwhichcomprisesofseveral
componentssuchas:-
A data acquisition system and
mass flow sensor would record
the amount of fuel delivered.
Several new technologies would
be introduced to the test rig. An
innovativepurewaterrecirculation
system would keep the water
losses in the electrolyzer at a
minimum consumption rate. The
control system would maximize
thehydrogenproductionefficiency
by regulating fluctuations in
electric power production caused
by changes in sunlight intensity.
Consequently,
research
on
minimizing the energy losses
associated
with

Terahertz (THz) wave refers to electromagnetic waves propagating in
frequencyrangebetween300GHzand3THz,correspondingtowavelength
regionfrom0.1mmto1.0mm.Itischaracterizedbyitsnon-ionizingnature
and are transparent to most non-conducting materials while not able to
penetrate metals and water. These characteristics have raised the interest
in research for terahertz wave generation and detection for applications in
securities,spectroscopyandTHzsensing.CurrentmethodofTHzgeneration
relieson synchrotron and bulk femtosecond laser as excitation source. It
is therefore important to research methods of THz wave generation using

Faculty : Department of Chemistry, Faculty of Science
Thisresearchpivotsaroundtheexploitationoffunctionalizedthiolateligands,
for example by including hydrogen-bonding functionality and/or multiple
metal binding sites, and their complexation by multifunctional bipyridinetype bases will lead to the generation of novel materials with applications
as luminescent materials, MOF’s, and as synthetic precursors for metal
sulphide nanoparticle production. This proposal is designed to overcome
thegenerallackofcontroloversupramolecularaggregationbytailoringthe
functionality and denticity of the ligands employed to assemble the metal
1,1-dithiolate synthons in the solid-state. The principles developed in this
research will have general applicability and therefore will form a secure
foundationforrelatedstudiesundertakenbyotherresearchers.Thetailored
materials will exhibit solid-state luminescence and different supramolecular

Methodology
Using principles of chemistry and
a full range of physiochemical
characterisation techniques, the
aims of this project above will be
realized primarily by adding metal
coordinating functionality and/

Objectives
Methodology The project is to synthesis/
grow, investigate and optimize
properties of low-dimensional
organic and inorganic thin-films
and nanostructures. Additionally,
the project aims to fabricate and
optimize advanced electronic
and
optoelectronic
devices
incorporating material-engineered
low-dimensional structures. Metal
organicchemicalvapordeposition
(MOCVD)systemisverycriticalfor
thisprojectasitistheonlyproven
technique for epitaxial growth
of high-quality single-crystalline
materials. The major novelty for
MOCVD growth in this project is
thatthethin-filmswillbegrownon
low-cost silicon substrate instead
ofexpensivesapphiresubstratein
conventional techniques by most
other research groups elsewhere.
The novelty would allow for the
realization of next-generation
advanced optoelectronic and
electronic devices at significantly
lowcost
The research will be carriedout
in
four
sub-projects,
comprising, (i) synthesis and
growth of low dimensional
materials, (ii) characterizations
of low dimensional materials,
(iii) fabrication of advance
optoelectronic and electronic
devices
incorporating
low
dimensional
structures,
and
(iv) optimization of devices
performance
by
materials
engineering. In synthesis and
growth sub-project, various low
dimensional structures will be
synthesized/grown by optimizing
the MOCVD growth parameters,
such as gas/vapor type, gas/
vapor ratio, gas/vapor flow rate,
growthtemperature,andchamber
pressure.
Subsequently,
the
material characterization subproject will include investigation
ofstructural,opticalandelectrical
properties, surface morphology,
crystal quality, compositional
profiles, defect analysis, crosssectional thickness, etc, using
advanced
characterization
techniques such as scanning
electron
microscopy
(SEM),
photoluminescence (PL), atomic
force microscopy (AFM), Hall
measurement, x-ray diffraction
(XRD), and transmission electron
microscopy (TEM). In device
fabrication
sub-project,
the
synthesized/grown
thin-film
structure will be fabricated into
operational devices, such as,
organic and inorganic lightemitting diodes, solar cells,
laser diodes, photo diodes, and
transistors.Thefabricationprocess
will include photolithography,
etching, metallization and hightemperature annealing. Finally, in
device optimization sub-project,
the properties of each thin-film
layer in the device structure will
be further optimized to obtain
high-performance energy-effcient
devices.
Advanced
material
engineering techniques such as
modulation doping, strained-layer
superlattices, lateral epitaxial
overgrowth and pendeo epitaxial
overgrowth would be beneficial
to significantly improve device
performanceandefficiency
Outcome
The
materials
synthesis/
growth method in this project
would open up possibilities
for innovative development of
various novel low-dimensional
structures and nanostructures.
The MOCVD epitaxial growth
technique in this project enables
innovative exploration in thin-film
growth such as strained-layer
superlattices(SLS),multi-quantum
well (MQW), quantum-dot (QD),
distributed Bragg reflector (DBR),
multilayer(ML)thin-filmstructure,
andnano-structures.Theadvance

Title: An Empirical Kinetic Approach to Study the Occurence
of Ion Exchange at the Aqueous Cationic Micellar Surface
Principal Investigator : Professor Dr. Mohammad Niyaz Khan
Theoccurenceofionexchangebetweencounterionsationicmicellarsurface
wasprobablyfirstdetectedbykineticstudy.Nowitseemscertainthatthis
is an ubiquitous feature of such a colloidal system. But the fine-detailed
mechanism(s) of the occurence of ion exchange at ionic micellar surface
remained essentially a major problem in various areas of interest. The ion
exchangeconstant(alsoknownasionselectivityconstant)forionexchange

techniques.
Viscoelasticity in dilute surfactant solutions has been of great interest.
It is believed that these viscoelastic systems form abnormally long (of
several hundred angstroms) cylindrical micelles which are responsible for
viscoelasticity.Itisoftenstatedintheliteraturethattheexistenceofthreadlike

methods. Hemolytic activities of
the peptides are evaluated using
erythrocyte cells by determining
spectrophotometrically
the
amount of haemoglobin (Hb)
released from 8% suspension
of fresh rabbit red blood cells
(RBCs).The variation in effect of
the peptides on cell morphology
will be examined by scanning

Principal Investigator : Professor Dr. Rauzah Hashim.
Glycolipids can be found extensively in cell membranes of prokaryotes
and eukaryotes. Their detailed chemical structure is functional to stabilize
membrane structure and assist in molecular-recognition at the cell-surface.

The former is involved in electrostatic interactions, mainly through the

Relative to the lyotropic, study on glycolipid thermotropic phase behaviour

Mesenchymal stem cells are multipotent stromal cells that can differentiate
intovariouslineagesandareknowntobehypo-immunogenicinnature.These
uniquepropertieshaveattractedtheattentionofcellbiologists,immunologists
as well as clinicians leading to initiation of pilot clinical trials for various
indications. However, MSC transplantation in humans has its own benefits
and risks. The presence of MHC-I and up-regulation of MHC-II expression
in the presence of host interferon-gamma are important determinants of
their use as immunomodulators. Safety profiling in terms of cytogenetic
instability, support of tumor growth, ectopic differentiation, fetal calf serum

It is well-established that cancer occurs as a result of a sequential
accumulation of genetic alterations. The ability to identify the specific
changes between normalcy and malignancy enables us to understand the

Title: Periodontal Disease: The Development of Genomic
Biomarkers and the Impact of Disease on Quality of Life
Principal Investigator : Dr. Rathna Devi Vaithilingam

Faculty of Dentistry
Periodontal disease, a chronic inflammatory disease which results in
irreversible attachment loss, bone destruction and tooth loss, is a major
oralhealthproblemaffecting90.2%ofMalaysianpopulation.5.5%ofthese
subjects have advanced periodontal disease. Although periodontitis is a
multi-factorial disease and microbial and environmental factors initiate and
modify disease progression, findings from several studies suggest that the
severity and progression of periodontitis might be associated with genetic
polymorphisms.Geneticallytransmittedtraitssuchasgenepolymorphisms
may accentuate the host’s inflammatory response to a bacterial challenge

proposetoidentifycandidategenesandpolymorphismsthatareassociated

We will use this framework to create a machine learning method that is
similar to human learning i.e. Human babies learn by associating vision
(representation of low level operations) with speech (labels or high level
relations,whichinturnisthebasisoflanguage).
WewillusetheaboveframeworktocreateanExpertSystemarchitecturefor

Summaryofresearchproposal
Project1:Contingentgeneregulatorynetworksinchondrogenesis:
Chondrogenesis is a stringently regulated, multistep cellular differentiation
program culminating in acquisition of the chondrocytic phenotype. The
process of chondrogenesis occurs in stages beginning with mesenchymal
cell recruitment and migration, proliferation and condensation, which are
regulated by mesenchymal- epithelial cell interaction. Several regulatory
factors have been identified to play a role in chondrogenesis, including the
positive transacting factors of the SOX family such as SOX9, SOX5, and
SOX6,aswellasnegativetransactingfactorssuchasC/EBPanddeltaEF1.

Another aspect of our research concerns the interaction of high-intensity

and the study of dynamical quantum proceses in atomic, molecular and
opticalsystems.Wealsostudyultracoldmatter,suchaslaser-cooledatoms,

Objectives
Methodology To develop state-of-the art
researchinvolvingquantumoptics,
optical materials and advanced
laser science, particularly to
study quantum coherence and
correlation in light and matter at
theatomiclevel
We
develop
theory
and
computational capabilities to
study the physics in the a)
generation, b) propagation and c)
interactions of novel light sources
in photonic structures and
quantum systems. This research
involves mathematical modeling
and theoretical study. Hence,
the research involves the
mathematical development of
the proposed formulation and the
skill of mathematical analyzing in
order to implement and solve the
nonlinear equations. A substantial
amount of study is involved in
developing the key framework in
nonrelativisticquantummechanics
and quantum electrodynamics.
These formalisms enable the
calculations to be performed
rigorously for light matter
interaction, ultra-high intensity
laser
propagation,
nonlinear
effects in wave propagation and
ultra-intense laser generation.
Thesimulationofopticalmaterials
may involve developing manybody quantum theory, a topic
of crucial importance in fields
ranging from quantum chemistry
and biochemistry to the study
of advanced materials such as
graphene,
high-temperature
superconductors and carbon
To develop and apply a
combination of cutting-edge
techniques to model dynamical
properties of photons, molecules
and nanostructures interacting
withintenselaserfields
nanostructures. This research
must also include the use of
computingskillsandsimulationsin
MathematicaorMatlabtoproduce
analytical results and numerical
results
In the case of ultra-high intensity
laser a lot of amazing nonlinear
effects can be studied by
combining
nonlinear
optical
processes with quantum optics.
The production of the ultra-high
energy pulse through nonlinear
interactions and high harmonic
generation lead to an efficient
generation of coherent X-ray
pulses.Atextremelyhighintensity,
the electromagnetic waves in the
vacuumcannolongerbeexplained
by the ordinary electrodynamic
theory. The Maxwell’s equation
has to be modified to include
nonlinearity of quantum vacuum.
Besides, the ultra-high intensity
laserinthenonlinearvacuum,such
laser can interact between each
other when they overlap. Hence,
the process leads to the creation
of photon-photon scattering and
photon splitting can be studied in
detail. The whole process would
be very interesting since it has
not been fully explored until very
recently

Title: Fundamental Sciences of Self-Assembly
Principal Investigator : Professor Dr. Rauzah Hashim.
Molecularself-assembliesfromlowmolarmassliquidcrystals(thermotropic
and lyotropic) are widely used in nanotechnology and life sciences. Many
well-known thermotropic applications include flat panel display devices,
while lyotropic liquid crystals are found pervasively in living systems and
their commercial applications include surfactants and emulsifiers. We
have conducted a wide range of research on self-assembly phenomena
includingsynthesizingaspecialclassofnon-ionicandenvironmentalfriendly
surfactantsbasedonglycolipid.Glycolipidsbelongtoaclassofliquidcrystal
material termed amphitropic since they can show both thermotropic and
lyotropic liquid crystalline properties. Hence the potential applications of

The present program focuses on
the followings: novel materials
for self assembly and related
phenomena (synthesis approach
and design). The self-assembly
structures of these materials
are studied by diffraction and
scattering
techniques
(eg.
SWAXS, SANS and synchrotron).
Some basic dynamics of self-
assembly will be determined
by using deuterium NMR and
time-resolved

microscopic theories for selfassembly phenomena. Aspects
of modeling and simulation
will be included to get detailed

studied,andseveralpublicationshavebeenproduced.
WiththeawardoftheHIRgrantfortheBreastCancerProjectinAug2011,
research has been divided into 5 programmes ie the Clincial Epidemiology
programme (includes the Malaysian Breast Cancer Cohort study and the
Breast Health Initiatives Study), the Genetics Programme, the Pathology
programme,theInvestigatorInitiatedTrials(IIT)programme,andtheImmune
Therapeutics (ITL) Programme. Each of these programmes has their own
leaders,andProfessorCHYipistheoverallPrincipalInvestigator.
Objectives
The objectives of this project are
to answer the following research
questions:
1.
Clinical Epidemiology: Why
do Malay women have
poorer survival? Is it lifestyle
or is it genetics? What are
the prognostic models that
may work well in the Asian
population?
2.
Genetics: Are there other
highriskgeneticmutationsin
the multiethnic population in
Malaysia and how do these
interactinbreastcancerrisk?

Title: The In Vivo Target Specificity and Function of HOX
Proteins
Principal Investigator : Dr. Lawerence Choo Siew Woh
Faculty : Dental Research & Training Unit, Faculty of Dentistry
The Hox genes form a genetic code for generating morphological diversity
alongtheantero-posteriorbodyaxisduringanimaldevelopment.Inaddition
tothemorphogenesis,Hoxgeneshavealsobeenshowntolinktooncogenesis
andhumandiseases.AllHoxgenesencodehighlyconservedDNA-binding
homeodomainandhavebeenshowntobindtoverysimilar/samesequences
in vitro (poor specificity) despite having distinct functions in vivo (high
specificity). Although they have been shown to regulate a wide variety of
downstream processes, direct transcriptional targets have been difficult to
identifyandthishasbeenamajorobstacletoourunderstandingofHoxgene

groupisinterestedtostudyhowHoxgeneticcodeworks.
Objectives
Methodology Outcome
TodecodehowHoxgeneticcode
works, we will embark on several
aspects of fundamental research
inthisprogramme:(1)understand
thebasisoftheHOXspecificity,for
example, by mapping the binding
sites of different HOX proteins
in the Drosophila cell lines, as
a model system. (2) the roles/
functions of HOX transcription
factors in development and gene
control, (3) to identify their target
genes which will give us insights
into how HOX proteins execute
their functions, (4) the association
between chromatin states and
HOX target selection, and (5) the
influence of cofactors on HOX
targetspecificity
We map the binding profiles
of different HOX proteins in
the Drosophila genome across
different time-points using whole
genometilingarrays.Thegenomewide expression profiles are also
generated across different timepoints.Byintegratingthebinding
and expression profiles, we could
look for functional target genes
directlyregulatedbyHOXproteins
and study the transcriptional
outputs determined by different
HOXtranscriptionfactors
specificityandrolesofHoxproteins
Extensive bioinformatic anayses
will be performed to identify
HOX-bound
regions,
target
genes, and to be used for other
downstream
analyses.
The
enrichment profiles of different
histone modification marks will
be determined at a genome-wide
scale using established ChIP-onCHIP technology. By identifying
the genomic regions marked by
theserepressive/activationhistone
marksandassociatedtargetgenes
on genome-wide scale, we have
an opportunity to compare and
associatetheHOXbindingprofiles
withchromatinstatesreflectedby
thesehistonemodificationmarks
PLoSBiology
In addition to the HOX projects,
we are also working on various
bioinformatics-related
projects
covering the following major
areas: software, database and
pipelinedevelopment,bioimaging,
comparative
genomics,
and
Next Generation Sequencing
(NGS) projects such as exome
sequencing, RNA-seq, genome
assembly and annotation, and
metagenomics

GUIDELINES ON TECHNICAL EVALUATION
1. Doestheprojectmeettheexpectationsofthe
HIRGrantScheme?
TheHIRGrantSchemefromtheUniversityofMalaya
is to fund projects which will result in publications in
Tier 1/ISI WoS journals. As such, the emphasis is on
fundamentalresearchwhichwillleadtothegeneration
ofnewknowledgeratherthanonthedevelopmentof
newproductsorpatents.
2. DothePrincipalInvestigator(PI)andthe

Itisimportanttolookattheprofessionalqualifications
andpastperformanceofthePIandhisteam.Weshould
refer to the records of the researchers with regard to
the type of projects funded, whether completed or
on-going and the outcome of those funded projects.
TheCVsofthePIandhiscollaboratorswillbeagood
indicatoroftheirrecordsandpreviousexperiences.
The budget should reflect on this collaboration, with
exchangesofvisitsbetweenthecollaboratingcentres.
Prominent Malaysian scientists working overseas
should be invited to participate in HIR projects and
funds provided to encourage them to be actively
involved. There should be documentary evidence to
show that the collaboration is active and meaningful
andwillleadtoanoutcomeofmutualbenefit.
7. AppropriatenessofResearchMethodology
Theresearchmethodologyintheapplicationformmust
containsufficientinformationfortheHIRCommitteeto
determinethefeasibilityoftheproject.FlowandGrant
charts of research activities must be provided and
the respective milestones and dates of achievements
provided. These will serve for the monitoring of the
projectoutcomes.
8. ResearchBudget
Inordertoavoidduplication,wemustensurethatthe
HIR project has not been funded elsewhere. There
shouldbeasubstantialdifferencebetweenthisproject
andthosepreviouslyconductedbytheresearchers.
Thebudgetrequestshouldberealisticandreflectthe
targetandcost-benefitsoftheproject.Theguidelines
fortheutilizationofHIRbudgetshouldgenerallybein
linewiththeguidelinesassetupbyothergovernment
ministriessuchasMOSTIandMoHE.However,more
flexibility will be allowed here subject to the approval
oftheVice-ChancellorwhoistheChairmanoftheHIR
Committee(refertoScopeofFundingintheGuidelines
forHighImpactResearchGrants).
4. Creditabilityofresearchobjectives
9. Cost-effectivenessofHIRProjects
The research objectives must be clear, accurate and
consistent and the proposed methodology relevant
to meet the set goals. It is important to ensure the
objectives are not too ambitious and that the goals
are achievable within the time period set. Objectives
mustbesetinsuchawaythattheyareverifiableupon
completionoftheproject.
The cost-effectiveness of the HIR project should be
relatedtothebudgetrequestandthenumberofTier
1 publications. If the merits of two proposals are the
same,thenitisobviousthattheonewithbettercostbenefitswillbegivenpriority.Asaruleofthumb,under
