7 mu M NAA and 1.1 mu M BAP. The period for dark and light culture was 20 days. Shoots were multiplied on MS medium, 30 g.L-1 sucrose supplemented with 1.1 mu M BAP. Shoots were elongated on MS medium free of plant growth regulators. Shoots were rooting on half-strength MS salts. Acclimatization was performed in a hydroponics floating system. Moreover, the shoot multiplication in liquid medium with different CaCl2 levels was carried out under agitation. Organogenesis selleck compound of cotyledonary nodes was characterized by simultaneous occurrence of shoot and callus. Shoots presented hyperhydricity under liquid medium, however, the CaCl2 reduces the hyperhydricity in
liquid medium; nevertheless, it SRT2104 had been not effective in eliminating hyperhydricity due to toxicity of
chlorine. The hydroponics acclimatization results in 90% plant survival. An efficient protocol for micropropagation of E. saligna was suitable established and can be used for clonal propagation or genetic transformation.”
“Addiction has been characterized as an attentional bias towards drug-related cues. In two experiments we investigate the effects of non-words that have been associatively trained to addiction-related images in a group of marijuana and cocaine users. These associated non-words were presented along with unstudied non-words in a subsequent addiction Stroop task. Results indicate a slowdown in responding to the colour of non-words that were paired with cocaine-related images compared with non-cocaine related images. The slowdown was also characterized as a carryover effect, with the largest effect occurring on trials following the addiction-associated non-word. No effects were found for marijuana images associated with non-words.”
“Animal models of ototoxicity represent an elementary tool in otolaryngologic research. Such models are usually created via the consecutive injection of ototoxic drugs
or the co-administration of ethacrynic acid and low-dose ototoxic drugs. Injection via the round window membrane (RWM) is one approach that allows for local drug delivery into the inner ear. In this study, 47 guinea pigs received an injection of varying GSI-IX nmr doses of cisplatin via the RWM, and data concerning the animals’ auditory brainstem responses, hair cells, and spiral ganglion neurons were analyzed. Our results indicate the high efficiency and generally small reaction of the subjects, suggesting that the application of cisplatin via the RWM is an effective animal model for ototoxicity research.”
“Background: Some reports have described the midst of the lumen of the bony eustachian tube to meet the lumen of the external ear canal more nearly straight in ears afflicted with otitis media.\n\nObjectives: To determine whether the “auditory tube angle” indeed is more nearly straight in ears with evidence of childhood otitis media.
