background: boron and gadolinium are among the nuclides that hold a unique property of being a neutron capture therapy agent. neutron beams have often a considerable portion of gamma rays with fast neutrons. gamma rays, as beam contaminants, can cause considerable damage to normal tissues even if such tissues do contain high boron concentrations. materials and methods: the modification of radio...
Low-Density Lipoprotein (LDL) extracted from egg yolk has recently known can eliminate the adverse effect associated in use of fresh yolk. The role LDL liquid preservation at 4°C ram sperm not been explored. This research evaluates effects substituting with 4 °C on 5 days. objective this was to assess for as an extender 4°C, well spermatozoa motility, viability, morphology, plasma membrane, and...
The infestation status of head louse among children attending primary schools and kindergartens in Chinju-shi, Kyongsangnam-do, Korea, was investigated between June and July 1999. Out of 2,288 children examined, 3.9% of boys (48/1,242) and 23.5% of girls (246/1,046) were infested with nits or adult/nymphs of lice. The effectiveness of lindane shampoo (1% gamma benzene hexachloride solution) was...
Macrocyclic tris-malonates incorporating cleavable di-tert-butylsilylene protecting groups have been prepared by a stepwise approach and used for the regioselective tris-functionalization of C60. Fullerene tris-adducts with an e,e,e addition pattern thus obtained. The bridging cleaved to liberate terminal alcohol functions fullerene tris-adduct. This key building block has further functionalize...
A tris-oxovanadium pyrogallate complex: synthesis, structure, and magnetic and electronic properties
A robust tris-oxovanadium tris-anion showing interesting electrochemical and magnetic properties due to the combination of V( iv ) with a non-innocent pyrogallate ligand.
A novel pH sensitive, colorimetric ionic liquid nanosensor based on phosphonium salts of fluorescein is reported. Herein, fluorescein salts of various stoichiometries were synthesized by use of a trihexyltetradecylphosphonium cation [TTP]+ in combination with dianionic [FL]2- and monoanionic [FL]- fluorescein. Nanomaterials derived from these two compounds yielded contrasting colorimetric respo...
