<p>Clove oil is an essential from the clove plant (<em>Syzygium aromaticum</em>) containing eugenol compounds. One of properties as anti-inflammatory with a mechanism inhibition prostaglandin synthesis and neutrophil chemotaxis. Several derivatives have active compounds that been developed into new drug such acetyl (4-allyl-2-methoxyphenyl acetate). This study aims to determin...

OBJECTIVE The objective of this study was to evaluate the effect of the labeling of umbilical cord vein derived mesenchymal stem cells with superparamagnetic iron oxide nanoparticles coated with dextran and complexed to a non-viral transfector agent transfector poly-L-lysine. METHODS The labeling of mesenchymal stem cells was performed using the superparamagnetic iron oxide nanoparticles/dext...

Ap Applicati tions ons in in Pl Plant t Scien Sciences ces Tetratheca erubescens J. P. Bull (Elaeocarpaceae) is a recently described species (Bull, 2007) endemic to the Koolyanobbing Range (a banded ironstone formation) within the Coolgardie Biogeographic Region of the South West Australian Floristic Region (SWAFR). Tetratheca erubescens inhabits rock crevices containing red sandy loam soils am...

The work presented in this thesis describes a rational design approach to the rapid detection of Bacillus anthracis spores. A range of assay formats are available for detection of B. anthracis, however none fulfil the criteria of speed, sensitivity or specificity. Optical biosensors have shown promise for the near real time detection of low molecular weight analytes, although exploitation of th...

The aim of this study was to formulate and evaluate zidovudine loaded chitosan microspheres for controlled drug release. Microspheres were prepared by emulsification method using gluteraldehyde as crosslinking agent. The prepared microspheres were characterized for their yield and drug loading, as well by Fourier transform infrared spectroscopy (FTIR), X-ray powder diffractometry and Scanning e...

Photoreactivation of ultraviolet (UV) radiation damage to organisms has been demonstrated in many plant and animal phyla.1 In a few cases, this repair process has been shown to involve a light-dependent photoreactivating enzyme which monomerizes U1-induced pyrimidine dimers in DNA.2 3 However, the biological phenomenon of photoreactivation does not necessarily indicate the involvement of a phot...

The chromatin immunoprecipitation (ChIP) assay is a valuable technique that allows researchers to establish what proteins (e.g., transcription factors) bind in vivo to a specific region of DNA, usually a gene promoter (1). In vitro proteinDNA binding assays, such as the electrophoretic mobility shift assay, are useful in identifying potential transcription factors that bind to a specific DNA se...

The heat shock response is a ubiquitous process described in prokaryotic as well as eukaryotic cells (Feige U., Mollenhauer J. 1992: Experientia 48: 621-622). This response is characterized by an induction, due to transcriptional activation, of a specific set of genes (Sorger P.K., Pelham H.R.B. 1987: EMBO J. 6: 993-998); the final products of this activation are the so called heat shock protei...

Promising applications of stem cell based therapy include the replacement of defective tissue in patients with diseases such as diabetes or Parkinson’s (1). To evaluate the success of engraftment, it is important to...
