In this study, we systematically screened and assessed the antibacterial efficacy of five chitosan preparations of different viscosities and components. Additionally, we explored the synergistic antimicrobial potential of the most potent chitosan sample in combination with commonly employed antibiotics, including ampicillin, amoxicillin, oxacillin, and levofloxacin against four prevalent BM-causing pathogens: Staphylococcus epidermidis, Streptococcus agalactiae, Streptococcus uberis and Pseudomonas sp.

The incidence of hypervirulent epidemic Clostridium difficile has increased around the world and now in Australia. Assays that are capable of rapidly identifying these strains would enable earlier diagnosis and timely infection control response. The aims of the first part of the study were to validate and develop a molecular technique for the rapid diagnosis of toxigenic C.

The document will be structured as follows: In Chapter 2 outline the methodology, discussing the computational techniques used to evaluate the interaction energies and evaluating the construction of the TT and D3(BJ) correction terms. Chapter 3 attempts to establish a foundational understanding of how these methods model vdW interactions by evaluating the performance of the corrected and uncorrected HF and DFT methods in comparison with CCSD(T) energies for a selection of inert gas dimers, and simple molecule-molecule interactions.

Chapter 5 - Molecular tools for studying genes and gene activity. This chapter describe the most popular techniques that molecular biologists use to investigate the structure and function of genes. Most of these start with cloned genes. Many use gel electrophoresis. Many also use labeled tracers, and many rely on nucleic acid hybridization. We have already examined gene cloning techniques.

Cytochrome c is widely distributed in bacterial species, from mesophiles to thermophiles, and is one of the best-characterized redox proteins in terms of biogenesis, folding, structure, function, and evolution. Experimental molecular biology techniques (gene cloning and expression) have become applicable to cytochrome c, enabling its engineering and manipulation. Heterologous expression systems for cytochromes c in bacteria, for use in mutagenesis studies, have been established by extensive investigation of the biological process by which the functional structure is formed. ...

A comparative study of thermodynamic and kinetic aspects of Cu(II) and Ni(II) binding at the N-terminal binding site of human and bovine serum albumins (HSA and BSA, respectively) and short peptide analogues was performed using potentiometry and spectroscopic techniques. It was found that while qualitative aspects of interaction (spectra and structures of complexes, order of reactions) could be reproduced, the quantitative parameters (stability and rate constants) could not.

The novel sex-specific potassium channel inhibitor IsTX, a 41-residue peptide, was isolated from the venom of male Opisthacanthus madagascariensis.Two-dimensionalNMR techniques revealed that the structure of IsTX contains a cysteine-stabilizeda/b-fold. IsTX is classified, based on its sequential and structural similarity, in the scorpion short toxin familya-KTx6. Thea-KTx6 family contains a single a-helix and twob-strands connected by four disulfide brid-ges and binds to voltage-gated K + channels and apamin-sensitive Ca 2+ -activated K + channels. ...

In this study we investigate the active-site structure and the catalytic mechanism of clostripain by using a combination of three separate techniques: affinity labelling, site-directed mutagenesis and molecular modelling. A benzamidinyl-diazo dichlorotriazine dye (BDD) was shown to act as an efficient active site-directed affinity label for Clostridium histolyticumclostripain. The enzyme, upon incubation with BDD in 0.1MHepes/NaOHbuffer pH 7.6, exhibits a time-dependent loss of activity.

We have used footprinting techniques on a wide range of natural and synthetic footprinting substrates to examine the sequence-selective interaction of the bis-daunorubicin anti-biotic WP631 with DNA. The ligand produces clear DNase I footprints that are very different from those seen with other anthracycline antibiotics such as daunorubicin and nogalamycin. Footprints are found in a diverse range of sequences, many of which are rich inGT (AC) or GA (TC) residues.

Bermuda grass pollen (BGP) contains a very complex mixture of allergens, but only a few have been characterized. One of the allergens, with an apparent molecular mass of 21 kDa, has been shown to bind serum IgE from 29% of patients with BGP allergy. A combination of chromato-graphic techniques (ion exchange and reverse phase HPLC) was used to purify the 21 kDa allergen.
