Rpon-Dependent Adaptation Of Burkholderia Xenovorans Lb400 For Biodegradation And Bioremediation Of Dibenzofuran / Noor Faizul Hadry Nordin, Nordin Noor Faizul Hadry

Student Works (2010-2019)

Alternative sigma subunit-54 (RpoN) forms holoenzyme complex when associated with core RNA Polymerase (RNAP) to specifically recognise and initiate transcription of specific sets of genes in response to environmental stimuli. RpoN has important role in many major adaptive responses in bacteria and is involved in various physiological responses such as pathogenesis, quorum sensing and bioremediation. The main focus of this study is to gain insight into the role of alternative sigma factor-54 (RpoN) of Burkholderia xenovorans LB400 in degradation of dibenzofuran via biphenyl degradation pathway. Additionally, this study also investigated the ability of Burkholderia cenocepacia J2315 in utilisation of dibenzofuran. …

Dynamics And Trophic Role Of Zooplankton Community In The Matang Mangrove Estuaries And Adjacent Coastal Waters (Peninsular Malaysia), With Special Emphasis On Copepods / Chew Li Lee, Li Lee Chew

Student Works (2010-2019)

Dynamics and trophic role of zooplankton community were studied in the Matang mangrove estuaries and adjacent coastal waters, Malaysia. Monthly zooplankton samples collected from May 2002 to October 2003 at five stations located from the upper estuary (7 km upstream) to 16 km offshore showed highest biomass and abundance of zooplankton at nearshore waters. Both standing stocks decreased towards upstream and offshore waters. Copepods (62% of total zooplankton abundance) dominated the zooplankton, followed by larvae of cirripede (18%) and polychaete (4%). Copepod abundance was higher during the wetter northeast (NE) monsoon and inter-monsoon (IN) period as compared to the drier …

Malaysia is a hot and humid tropical country that has yearly mean temperature between 24°C and 33°C and relative humidity between 70% and 90% throughout the year. Thus, overheating is a paramount problem in residential buildings. Although air conditioning can solve this problem, it will consume a large amount of electricity and also causes environmental problems. Moreover, the concern of sick building syndrome has resulted in a resurgence of interest in naturally ventilated rooms. The action of opening a window is the most intuitive and simple response to controlling overheating in a room. Even so, if the window opening dimension …

An Empirical Assessment Of The Bootstrap Support As An Indicator Of Robustness In Phylogenetic Trees / So Wei Huo, Wei Huo So Jan 2012

An Empirical Assessment Of The Bootstrap Support As An Indicator Of Robustness In Phylogenetic Trees / So Wei Huo, Wei Huo So

Student Works (2010-2019)

Bootstrapping is a de-facto standard for displaying the validity of a phylogenetic tree. However this may not be the case as bootstrapping assume that the random sequence exist within the genome. In order to examine whether bootstrapping is a valid process, it must be done empirically. Across multiple taxa there are minimal fully curated genomes but there are mitochondrion genomes available to test this. A widely accepted evolutionary tree is chosen with 6 taxa - Pan paniscus (bonobo), Homo sapiens (human), Gorilla gorilla (gorilla), Pongo pygmaeus (orangutan), Hylobates lar (common gibbon) and Gallus gallus (red junglefowl) as the outgroup.

Transportation sector has a dominant role in global fuel consumption and greenhouse gas emissions. Due to the dramatic increase in greenhouse gas emission, sustainable development of this sector has raised the concern in many countries including Malaysia. Biodiesel is a renewable energy that has great potential to serve as an alternative fuel to fossil diesel in the compression ignition (CI) engine. Although Malaysia is one of the biggest biodiesel fuel producers, the commercialization of biodiesel has not been fully undertaken in a large scale. Besides the technical barriers, there are several nontechnical limiting factors, which impede the development of biodiesel. …

Synthesis And Self-Assembly Studies Of Glycoside Surfactants And Chromonics / Faramarz Aliasghari Sani, Faramarz Aliasghari Sani

Student Works (2010-2019)

This thesis focused on the synthesis and self assembly studies of compounds involving carbohydrates. Two different types of materials were studied, i.e. surfactants and chromonics. Physical investigations of the compounds were conducted by TGA, DSC, OPM, UV-Vis spectroscopy, 1H NMR and surface tension measurements. Sugar-based surfactants are interesting compounds for pharmaceutical and personal care products. Current commercially available surfactants such as alkyl poly glucoside surfactants (APGs) are prepared from low miscibility of sugars and fatty alcohols. In order to solve the miscibility problems of the starting materials, homogenizers are required. This, however, leads to impurities in products, which affects the …

Diagnosis of ovarian carcinoma is in urgent need for new complementary biomarkers for early stage detection. In order to find an alternative procedure to replace an uncomfortable conventional method in detecting cervical cancer, a proteomic approach in screening the urinary proteins were employed. Proteins that are aberrantly excreted in the urine of cancer patients are excellent biomarker candidates for development of new non-invasive protocol for early diagnosis and screening purposes. In the present study, urine samples from patients with ovarian carcinoma and cervical cancer were analysed by two-dimensional gel electrophoresis (2-DE) and the profiles generated were compared to those similarly …

Effects Of Brucea Javanica And Piper Betle Extracts On Oral Candida Spp / Mohd-Al-Faisal Nordin, Nordin Mohd Al-Faisal

Student Works (2010-2019)

Candida species is an opportunistic microorganism residing in the human oral cavity. There is increasing prevalence of candidal infections in the oral cavity largely because of the increasing size of the population at risk. The rise in diagnosed cases of oral candidiasis is also due to the immunosuppressive effect of prescribed antifungal agents on resistant hosts. The ability of Candida species to adhere on mucosal tissues and/or denture surfaces, and the production of hydrolytic enzymes along with defective host immunity are among the known key factors of invasions and pathogenesis of oral candida. Although Candida albicans remains as the most …

The Development Of Single-Chain Variable Fragment (Scfv) Antibodies Against Toxoplasma Gondii By Phage-Display / Sherene Lim Swee Yin, Sherene Swee Yin Lim

Student Works (2010-2019)

The obligate intracellular protozoan parasite, Toxoplasma gondii, is the etiologic agent of an opportunistic infection affecting mainly immunocompromised patients, infants and neonates with immature immune system. There is a need for alternative antiparasitic treatment for toxoplasmosis due to the associated toxicity and teratogenicity of the current drug treatment regime. To investigate a potential alternative strategy, we have used the phage-display system and developed a novel biopanning procedure to isolate single-chain Fv (scFv) antibodies probed against tachyzoites – the rapidly replicating form of T. gondii responsible for acute disease. The resulting scFv antibody library (complexity of 1.62 X 104 independent transformants) …

Student Works (2010-2019)

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the main bacterial pathogens responsible for a variety of nosocomial infections ranging from soft-tissue infections to bacteremia. Since most MRSA is often resistant to multiple antibiotics, this has raised a concern over the limited choice of antimicrobial-agents for treatment of life-threatening cases. The objectives of this study were to determine the antimicrobial resistance profiles, presence of resistance and virulence genes, to investigate the molecular epidemiology of MRSA and their evolution over a six-year period. The antibiograms of 188 MRSA strains isolated from UMMC were analyzed by disk-diffusion test and minimum inhibitory concentrations. The …
