Emerging research in mammalian cells suggests that ionic (AgNO3) and nano silver (AgNP) can disrupt the metabolism of selenium which plays a vital role oxidative stress control. However, effect (Ag) on selenoprotein function fish is poorly understood. Here we evaluate effects AgNO3 citrate coated AgNP (cit-AgNP) using cell line derived from rainbow trout (Oncorhynchus mykiss) intestine (RTgutGC...

background & aim: lemon verbena (lippia citriodora h.b.k.) is a richly scented herb and has a long history as a sacred and medicinal plant. select an appropriate medium in tissue culture is a necessity for success experimental: to evaluate the effect of 10 medium of previous researches for lippia micropropagation (1- ms medium supplemented with bap (3 mgl-1) + iba (0.1 mgl-1) + activated ch...

A solution based laser direct write technique for patterning of glass substrates with silver nanoparticles is presented. Photoreduction of an AgNO3 solution, by nanosecond UV laser pulses, produces a source solution of silver particles. A glass substrate is then inserted into this solution and the laser is scanned over its surface. Laser-induced fragmentation of the silver particles in the solu...

The title compound, [Ag2(NO3)2(C14H38B10P2)2]·2CH2Cl2, was synthesized by the reaction of 1,2-bis-(diiso-propyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane with AgNO3. The resulting dinuclear molecule has crystallographically imposed inversion symmetry. The diiso-propyl-phosphanyl-closo-carborane ligand is coordin-ated in a bidentate manner to the Ag(I) atom through the two P atoms. The distor...

Marking excision margins of surgical specimens by silver impregnation has several advantages over commonly used Indian ink: during the slicing the tissue preserves its natural color, the staining is permanent, and the pigment does not smudge over cutting surfaces. The pigment is clearly visible in tissue sections. The tissue specimen is shortly dipped into a 10% water solution of argent nitrate...

Somatic embryogenesis could be achieved in Themeda quadrivalvis (Linn.) O. Ktze -fodder grass species on MS medium supplemented with 2,4-D. Incorporation of putrescine in the medium stimulated embryogenesis, however its lower concentration stimulated production of non-regenerative callus. Other polyamines such as spermine and spermidine could not evoke similar response. Ascorbic acid used as an...

Bugs (Insecta: Heteroptera) are frequently used as examples of unusual cytogenetic characters, and the family Cimicidae is one of most interest in this respect. We have performed a cytogenetic study of the common bed bug Cimex lectularius Linnaeus, 1758 using both classical (Schiff-Giemsa and AgNO3-staining) and molecular cytogenetic techniques (base-specifi c DAPI/CMA3 fl uorochromes and FISH ...
