Formalin-fixed tissue has been a mainstay of clinical pathology laboratories, but formalin alters many biomolecules, including nucleic acids and proteins. Meanwhile, frozen tissues contain better-preserved biomolecules, but tissue morphology is affected, limiting their diagnostic utility. Molecular fixatives promise to bridge this gap by simultaneously preserving morphology and biomolecules, en...
In the past conventional bacteriological techniques have misidentified Gram negative organisms such as Stenotrophomonas maltophilia as Burkholderia cepacia due to colonial and phenotypic similarities. Identification is extremely important as B. cepacia has severe consequences for CF patients which ultimately lead to death. Categorisation with B. cepacia has implications for infection control, p...
The rate at which the transmitter release machinery is fixed by 2% glutaraldehyde at hippocampal synapses and the amount of release evoked by the fixative have been investigated. We recorded from hippocampal cells while fixative was applied with a rapid flow system. Release is blocked in less than a second and fixative-produced exocytosis is at most a few percent of what would be caused by a hy...
Purpose: The purpose of this study was to investigate the immediate effects of low power laser radiation (Ga-Al-As; 830nm) on the seminiferous epithelium of Sprague-Dawley rats. Materials and Methods: Male Sprague-Dawley rats were randomly divided into three groups (two experimental groups and the sham). The left testes of the animals were shaved, washed and marked at inferior pole. Then, they...
Raman spectroscopy is a non-invasive and non-destructive tool that has been widely applied in Agricultural and Bio-system Engineering field. It provides a unique “fingerprint” to different chemical, and structural, information at molecular level. Acquisition of Raman spectrum requires a relatively short collecting time and minimum sample preparation, which makes Raman spectroscopy an attractive...
