Environmental biomonitoring has demonstrated that organisms such as crustaceans, fish and mushrooms are useful to evaluate and monitor both ecosystem contamination and quality. Particularly, some mushroom species have a high capacity to retain radionuclides and some toxic elements from the soil and the air. The potential of mushrooms to accumulate radionuclides in their fruit-bodies has been we...

The radioactive background of the eastern side Lesvos Island in Greece, an island rich natural radioactivity, was studied by means gamma ray spectroscopy. Dose rates and concentrations radionuclides (232Th series, 226Ra 40K) 137Cs were measured in-situ laboratory, respectively. A total twenty soil samples ten beach sand collected processed according to IAEA protocol. For measurement dose rate d...

The presence of heavy radioactive minerals in the studied granitoids from which Wadi sediments leads to study exposure emitted gamma rays terrestrial radionuclides, such as 238U, 232Th, and 40K. geological revealed that derived surrounding granitoids, syenogranite, alkali feldspar granite, quartz syenite. mineral analysis confirmed were enriched with minerals, uranothorite well monazite, zircon...

The general properties of the heat shock response in Pseudomonas aeruginosa were characterized. The transfer of cells from 30 to 45 degrees C repressed the synthesis of many cellular proteins and led to the enhanced production of 17 proteins. With antibodies raised against the Escherichia coli proteins, two polypeptides of P. aeruginosa with apparent molecular weights of 76,000 and 61,000 (76K ...

To quantify the solute permeability of rat cerebral microvessels, we measured the apparent permeability (P) of pial microvessels to various sized solutes. The pial microcirculation was observed by a high numerical aperture objective lens through a section of the frontoparietal bone thinned with a micro-grinder (a revised method from Easton and Fraser, 1994, J Physiol. 475:147-157, 1994). Sodium...

Specific activites of natural (40K, 226Ra and 40Th) anthropogenic (137Cs) radionuclides in 30 glutinous rice samples bought from some local retailers department stores Songkhla Province have been measured analyzed. Experiment results were carried out by using a high-purity germanium (HPGe) detector gamma spectrometry analysis system at Radiation Laboratory Thailand Institute Nuclear Technology ...
