Screening of random oligonucleotide libraries with SELEX [systematic evolution of ligands by exponential enrichment; Tuerk, C., & Gold, L. (1990) Science 249, 505-510] has emerged as a powerful method for identifying high-affinity nucleic acid ligands for a wide range of molecular targets. Nuclease sensitivity of unmodified RNA and DNA, however, imposes(More)
The tentacle withdrawal reflex in the terrestrial snail Helix aspersa involves bending and retraction of the tentacles. When elicited by mechanical stimulation of the tentacle, the reflex is mediated by the conjoint action of the central and peripheral nervous systems. The neural circuit underlying the stimulus-response pathways was studied in vitro using a(More)
Hydroperoxides are the primary oxygenated products of polyunsaturated fatty acids and are key intermediates in the octadecanoid signalling pathway in plants. Lipid hydroperoxides (LHPO) were determined spectrophotometrically based on their reaction with an excess of Fe(2+)at low pH in the presence of the dye xylenol orange. Triphenylphosphine-mediated(More)
Menthol and related compounds were investigated for modulation of recombinant human gamma-aminobutyric acid type A (GABA(A), alpha(1)beta(2)gamma(2s)) receptor currents expressed in Xenopus oocytes. Sub-maximal (EC(20)) GABA currents were typically enhanced by co-applications of 3-300 microM (+)-menthol (e.g. by approximately 2-fold at 50 microM) >(More)
Male Sprague-Dawley rats were assigned to one of three dietary groups [standard diet (Cont; n = 8), standard diet plus bovine colostrum powder (BColost 1.7 g/kg; n = 8), or goat milk powder (GMilk 1.7 g/kg; n = 8)] to determine the ability of these supplements to reduce gastrointestinal hyperpermeability induced by heat. Raising core body temperature of(More)
GABA(A) receptors meet all the pharmacological criteria required to be considered important general anaesthetic targets. In the following study, the modulatory effects of various commercially available and novel cyclohexanols were investigated on recombinant human γ-aminobutyric acid (GABA(A), α(1)β(2)γ(2s)) receptors expressed in Xenopus oocytes, and(More)
The effect of tenotomy on Extensor Digitorum Longus (EDL) muscle, brought about by removal of anterior tibialis muscle was studied in the rat. Hypertrophy as well as hyperplasia of the muscle fibres were observed following tenotomy of intact muscle. The transplanted muscle regenerated after tenotomy in the form of a flat strap. The weight, length, breadth(More)
Hydroperoxides are the primary oxygenated products of polyunsaturated fatty acids and were determined spectrophotometrically based on their reaction with an excess of Fe2+ at low pH in the presence of the dye Xylenol Orange. Triphenylphosphine-mediated hydroxide formation was used to authenticate the signal generated by the hydroperoxides. The method(More)
Effect of exercise has been studied on intact and transplanted extensor digitorum longus (EDL) muscle in rats. Majority of muscle fibres hypertrophied and a few showed hyperplasia in intact and transplanted EDL muscle after exercise. The weight, dimensions and diameter of muscle fibres increased, while total muscle area, number of muscle fibres and the(More)
