Spontaneous configuring in conditioned flavor aversion.

Four experiments with 202 rats investigated spontaneous configuring, using the conditioned flavor-aversion paradigm. In Exp I, extended training of a 2-flavor compound stimulus did not produce spontaneous differentiation of conditioned responding to that compound and its elements. In Exp II, it was found that extended nonreinforced exposure to a compound stimulus generated spontaneous element–compound differentiation when the elements were later conditioned. Ss that received extended preexposure to the compound showed less conditioned responding to the compound than to either of its elements. However, Ss that had not received preexposure to the compound showed greater conditioned responding to the compound than to either of its elements (summation). In Exp III, nonreinforced preexposure to a compound stimulus prior to minimal reinforced compound training produced spontaneous compound–element differentiation, but extended reinforced compound training eliminated that differentiation. In Exp IV, extended partial reinforcement training with a compound produced differentiation of the compound from its elements. Implications of these data for the mechanisms responsible for spontaneous configuring, and for the summation assumptions common to most learning theories, are discussed.

铝钛渣对镁质复合材料烧结性能的影响简

 为了探索铝钛渣对镁质复合材料烧结性能的影响,提高镁质复合材料的使用性能,试验用电熔镁砂、高纯镁砂、氧化铝微粉和氧化铬微粉为主要原料制备镁质复合材料。用热膨胀仪对比烧前和烧后镁质复合材料的线膨胀率和线膨胀系数,结果表明,烧前镁质复合材料的线膨胀率和线膨胀系数为1100~1300℃,会出现较明显的增大趋势,烧后镁质复合材料的线膨胀率未出现显著增大的趋势,而线膨胀系数随着铝钛渣加入量的增大而逐渐减小。铝钛渣对镁质复合材料有促烧结作用,经1100和1500℃烧后的镁质复合材料体积密度和常温抗折强度随铝钛渣加入量增大而逐渐增大。     

Studies on the conversion of oestradiol linked to a cytostatic agent (Estracyt) in various rat tissues

Estracyt, a compound of nitrogen-mustard linked to oestradiol phosphate, is used in the treatment of human prostatic cancer. The metabolism of this compound has been studied in different tissues of the rat both in vivo and in vitro. The phosphate group in position 17 of the oestradiol moiety is rapidly split off from the compound. An oestrone-cytostatic compound was extractable from the liver half an hour after the injection of Estracyt. In addition the in vitro results showed that only the liver was able to convert the oestradiol-cytostatic compound to an oestrone-cytostatic one. When animals were killed 24 h after a 3-day period of Estracyt treatment, the dominating metabolite in the ventral prostate was an oestronecytostatic compound, but traces of free oestrone could also be demonstrated. No such compound, however, was found in liver, diaphragm or blood at this time. It is concluded that in vivo an oestrone-cytostatic compound seems to be preferentially retained in the ventral prostate after Estracyt injection whilst the metabolic conversion of the oestradiol-cytostatic compound into an oestrone-cytostatic one possibly occurs in the liver.

Dissociation of stimulus compounds by pigeons.

Used a matching-to-sample (MTS) procedure to investigate short-term memory for compound visual stimuli in 10 mixed-breed pigeons. In Exp I, a symbolic MTS procedure was used. Three Ss were trained to match element samples, and 3 were trained to match compound samples. Findings indicate that the compound-trained group did not learn to match the compound samples in terms of element matching rules but rather processed them as unitary events. In Exp II, Ss were trained to match either element or compound samples in a true MTS task. Both groups were able to match elements and compounds in the transfer test. Findings show that at least some compound stimuli were represented in a unitary, nonanalytic fashion until the S was exposed to the elements of the compound in isolation from the compound.

Summation and configuration in conditioning of the rabbit's nictitating membrane response to compound stimuli.

Two experiments, with 64 female albino rabbits, examined the acquisition of the nictitating membrane response to a tone plus light compound and its components in (a) compound conditioning (CC), which entailed reinforced presentations of the compound; and (b) stimulus compounding (SCP), which entailed reinforced presentations of the separate components. In CC, responding to the compound reached high levels, but the level of responding on component test trials declined to low levels as the conditioned stimulus (CS)–unconditioned stimulus (UCS) interval was increased. In SCP, there was substantial responding to both components, but all groups showed even higher levels to the compound. In Exp II, Ss received reinforced presentations of the compound and its components in proportions intermediate to those of CC and SCP. Differentiation between the compound and its components increased as the proportion of reinforced compound trials increased. Results are discussed with respect to atomistic summation and to perceptual, distributive, and unique stimulus hypotheses. (42 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Assessment of metabolites in bioequivalence studies: should bioequivalence criteria be applied on the sum of parent compound and metabolite?

OBJECTIVES: The objective of this study was to demonstrate the impact of the sum of parent compound and metabolite in bioequivalence assessment. METHODS: Four drugs with active metabolite were selected to assess bioequivalence. Bioequivalence criteria of 80 - 125% were applied to the parent compound, the metabolite, and the sum of parent compound and metabolite. RESULTS: The results indicated that the application of 80 - 125% bioequivalence criteria to the sum of parent compound and metabolite might be misleading. CONCLUSION: The 90% confidence interval should be applied separately to the parent compound and each metabolite.
