The Effect of Nanoconfined Liquid Properties on the Water-Responsive Behavior of Bacterial Cell Walls
… powerful, for example <em>Bacillus subtilis</em> cell walls display record-high actuation energy and power densities of 72 MJ m<sup>-3</sup> and 9.1 MW m<sup>-3</sup>, surpassing those of all existing muscles and actuator materials. They hold great potential to be used as high-performance …

Molecular modelling assisted design and synthesis of cyclothialidine derivatives as DNA gyrase inhibitors
… is attributable to its inability to penetrate bacterial cell walls and membranes. We applied the TSAR programme to generate a QSAR equation to the gram-negative organisms. In that equation, LogP is profoundly indicated as the key factor influencing the cyclothialidine activity against bacteria. …

Utility of Ion Mobility – Mass Spectrometry in Peptidoglycan Structural Determination
The peptidoglycan (PG) found within bacterial cell walls is a complex megastructure with components that are difficult to identify without significant time commitment. Potential isomers, modifications, and cross-linking patterns within whole cell digests lead to complex samples that typically …

Role Of Crebh In Endotoxin Mediated Modulation Of Hepatic Metabolism
<p>Bacterial endotoxins can induce a variety of physiological changes in the host. This effect is not only restricted to inflammatory changes but also comprises metabolic changes in the host body. Lipopolysaccharide (LPS), one of the key components of the bacterial cell walls, is capable of …

Molecular characterization and in vitro functional analysis of putative immunoprotective molecules in the soft tick, Ornithodoros savignyi
… glucosamine of the peptidoglycan layer of bacterial cell walls affording the molecule antibacterial activity. In argasid ticks, lysozyme was observed to be induced by feeding. In chapter 3, an attempt was made to elucidate the O. savignyi homolog of the O. moubata lysozyme molecule. The …

Sequestration of metal and metalloid ions by thermophilic bacteria
… groups (potential ligands) within and onto the bacterial cell walls. Data obtained from electrophoretic mobility, potentiometric titration and cadmium ion adsorption experiments were used to quantify the number and concentrations of ligands and to determine the thermodynamic stability constants …

Liposome-loaded biosynthetic bacterial cellulose hydrogels for wound management applications
… process. In the present study, biosynthetic bacterial cellulose hydrogels were synthesised by Gluconacetobacter xylinus (ATCC 23770) and loaded with antimicrobial agents. Characterisation studies were carried out on these biosynthetic hydrogels for their wound healing properties. Due to the …

The role of elastase as an inflammatory stimulus in chronic obstructive pulmonary disease
… smoke and lipopolysaccharide (LPS) from bacterial cell walls, have been associated with disease development and progression. Consequently, there are associated increases in inflammatory cytokines such as TNF? in the COPD patient. Although inflammation plays a major role in the …

The effect of age on the structure and compostition of the cell walls of Choanephora cucurbitarum
… and composition of isolated and purified cell walls from cultures of Choanephora cucurbitarum was investigated by microchemical analyses, visible and infrared spectrophotometry, x-ray diffractometry and electron microscopy. Qualitative evaluation revealed the presence of lipids, proteins, …

INSIGHTS INTO THE METAL HANDLING MECHANISMS OF TITANIUM DIOXIDE-BINDING BACTERIA RHODOCOCCUS RUBER
… Titanium has a wide range of uses due to its excellent properties such as high strength-to-weight ratio, corrosion resistance, and biocompatibility. Despite its abundance and being readily absorbed by certain organisms, no essential biological function for titanium has been identified. …

Development of methods for the microbiome analysis of formalin fixed paraffin embedded tissue specimens
… understanding of FFPE-induced changes to the bacterial cellular structure and its DNA content, that a reliable method can be developed It is hypothesised here that with a sample-prep workflow considering the effects of FFPE on bacterial cells, their DNA content and the overall contamination …
