The biokinetics of Cs in four compartments in the green-lipped mussel Perna viridis, namely, gill, viscera, adductor muscle, and foot, were studied. First-order linear differential equations were set up for these four compartments, and their solutions were used to fit the experimental data. The parameters governing the biokinetics, which depend on the elimination rate from each compartment and ...

Plastic waste is a solid that difficult to decompose but can turn into environmental microplastics. Microplastics are sizes between 0.1 μm–5 mm, highly prolific anthropogenic pollutants affecting terrestrial, freshwater, and marine ecosystems. The purpose of this study was determine the ability Babylonia spirata accumulate eliminate polystyrene This experiment uses nuclear applications techniqu...

Radioiodine scintigraphy influences staging and treatment in patients with differentiated thyroid carcinoma. The limit of detection for fractional uptake in an iodine avid focus in a scintigraphic image was determined from the number of lesion net counts and the count density of the tissue background. The count statistics were used to calculate the diagnostic activity required to elevate the si...

UNLABELLED The biologic evaluation in living rats of (68)Ga-labeled oligonucleotides as imaging agents for PET is reported. METHODS (68)Ga, a positron-emitting radionuclide (half-life, 68 min), along with a macrocyclic chelating agent, 1,4,7,10-tetraazacyclododecane-N,N',N",N"'-tetraacetic acid (DOTA), was used for labeling of antisense oligonucleotides targeting activated human K-ras oncogen...

Biokinetics data of lung-administered PEI F25-LMW/siRNA polyplexes within different lung compartments are presented. Thereby, at three different timepoints (1 h, 3 h, 8 h), the data was determined by calculations to the 32P-radioactivity in the whole mouse body. Additionally, data was optimized to the available PEI F25-LMW/siRNA polyplexes in the target organ and therefore normalized to the sum...

In the foregoing pages the writer has attempted to point out first, the importance to physiologists of the discovery and application to their problems of a unit of physiological activity to serve as a universal measure of life processes. Second, a survey of the field of excitation and response points to the probability that electron transfers are involved in every case and, therefore, that such...

Strobilurins are one of the most important classes of agricultural fungicide. Their invention was inspired by a group of fungicidally active natural products. The outstanding benefits they deliver are currently being utilised in a wide range of crops throughout the world. First launched in 1996, the strobilurins now include the world's biggest selling fungicide, azoxystrobin. By 2002 there will...
