T1 - Binding and degradation of juvenile hormone III by haemolymph proteins of the Colorado potato beetle: a re-examination N2 - The haemolymph of the adult Colorado potato beetle, Lepinotarsa decemlineata Say, contains a high molecular weight (MW > 200,000) JH-III specific binding protein. The Kd value of the protein for racemic JH-III is 1.3 ± 0.2 × 10−7 M. It has a lower affinity for racemic JH-I and it does not bind JH-III-diol or JH-III-acid. The binding protein does discriminate between the enantiomers of synthetic, racemic JH-III as was determined by stereochemical anaysis of the bound and the free JH-III. Incubation of racemic JH-III with crude haemolymph results in preferential formation of (10S)-JH-III-acid, the unnatural configuration. The JH-esterase present in L. decemlineata haemolymph is not enantioselective. It is concluded that the most important function of the binding protein is that of a specific carrier, protecting the natural hormone against degradation by esterases. The carrier does not protect JH-I as efficiently as the lower homologue.

An attempt is made to account for the conflicting points of view in this disagreement in terms of certain issues that have engaged philosophers of science in the 20th century. It is hoped that, in passing, something useful is learned about research of many types on psychotherapy.

T1 - Dyslexic and normal readers' eye movements N2 - Dyslexic and normal readers' eye movements were compared while tracking a moving fixation point and in reading. Contrary to previous reports, the dyslexic and normal readers did not differ in their number of saccades, percentage of regressions, or stability of fixations in the tracking task. Thus, defective oculomotor control was not associated with or a causal factor in dyslexia, and the dyslexics' abnormal eye movements in reading must be related to differences in higher cognitive processes. However, individual differences in oculmotor efficiency, independent of reading ability, were found within both the dyslexic and normal groups, and these differences were correlated in reading and tracking tasks.

Among various cell fractions, microsomes have the highest specific activity. A homogeneous enzyme preparation is obtained in a six-step purification procedure. The final preparation appears homogeneous upon dodecyl sulfate electrophoresis, but analytical isoelectric focussing reveals various active bands with isoelectric points in the range of pH 3 - 4. The enzyme is a glycoprotein containing about 30% carbohydrate. Treatment with neuraminidase lowers the isoelectric points but does not reduce the heterogeneity of the band pattern. The subunit molecular weight is 120000 as estimated by dodecyl sulfate electrophoresis, whereas Mr of the native enzyme is > 200000, as can be concluded from gel filtration experiments. The purified dipeptidyl peptidase cleaves various synthetic and natural peptides, including substance P, kentsin, casomorphin and a synthetic renin inhibitor. In general, the specificity of the placenta peptidase is similar to that of post-proline dipeptidyl peptidase from other sources. Phenylalanylprolyl-P-naphthylamide (Km = 0.02 mM, I/ = 92 Ujmg) is the best substrate among various synthetic peptide derivatives. Only peptides with a free N-terminal amino group and proline, hydroxyproline, or alanine in position 2 of the N-terminal sequence are cieaved. However, X-Pro-Pro- . . . structures, e. g. as in bradykinin, are not attacked. 1 mM bis-(6nitrophenyI)phosphate or 1 mM diisopropylfluorophosphate completely inactivate the peptidase within 30 min at 30°C (pH 8). The peptidase is also completely inhibited by 1 mM Zn²⁺ and by other heavy metals.

T1 - Regression analyses as a tool for studying reading processes : comment on Just and Carpenter's eye fixation theory N2 - Just and Carpenter (1980) presented a theory of reading based on eye fixations wherein their "psycholinguistic" variables accounted for 72% of the variance in word gaze durations. This comment raises some statistical and theoretical problems with their use of simultaneous regression analysis of gaze duration measures and with the resulting theory of reading. A major problem was the confounding of perceptual with psycholinguistic factors. New eye fixation data are presented to support these criticisms. Analysis of fixations within words revealed that most gaze duration variance was contributed by number of fixations rather than by fixation duration.

The package requires the data to be in a fixation format and to be rescaled to screen dimensions. OLDEYE identifies six types of fixations and calculates descriptive statistics on each of them, on their associated saccades, and on their average pupil diameter. CONVRT represents the text as a string of words that can be coded according to experimentally relevant variables. PLTFIX prints fixation durations by letter position and sequence of occurrence. MODDAT is an interactive program for marking parts of the text in which the data quality is below acceptable standards. It also allows the correction of systematic errors due to calibration or drift. MATCH combines the outputs from OLDEYE, CONVRT, and MODDAT and calculates 11 dependent measures for every word. The output of MATCH is suitable for input to conventional multivariate statistical programs.

T1 - Reduction and calibration of eye monitor data N2 - The present paper presents FORTRAN programs for reducing eye monitor output to fixations and for mapping these fixations to locations in the stimulus space. Flexible parameters of the fixations program allow for determination of the beginning and end of fixations under different resolution criteria and for indicating loss of accurate measurement. The calibration program is based on a rectangular 9-point fixation grid. Each fixation is rescaled within this grid by solving for a quadratic equation. The rescaled values are output in a flexibly determined rectangular coordinate system that is related to the stimulus space, such as character position on the screen. The programs were developed for the 60-Hz Applied Sciences corneal reflection eye monitor, but they may be used with a number of other systems.

T1 - Products of in vitro oxidation of N-acetyldopamine as possible components in the sclerotization of insect cuticle N2 - [1-14C]-N-Acetyldopamine (NADA) was oxidized in the presence of methyl [3-3H]-β-alanate with mushroom tyrosinase. The complex mixture of reaction products was partly resolved by chromatographic procedures and analyzed by spectroscopic methods. Methyl-β-alanate is incorporated to only a small extent into oxidation products of NADA which inter alia are presumed to be oligomeric hydroxyquinones. After oxidation of [1-14C, 2-3H]-NADA with preparations from tanning Manduca sexta pupal cuticle, N-acetylnoradrenalin was identified as one of the products. Binding of radioactivity to melanin-like material was also observed. These results suggest that oxidation products different from those formulated usually for the crosslinkages between protein amino groups and N-acetyldopaquinone are deposited in darkly brown coloured insect cuticles during sclerotization.

T1 - Guillermo del Toro’s Hellboy: A Kinder, Gentler, More Modern Heracles JF - thersites 17 N2 - In Hellboy (2004, Sony Pictures), Guillermo del Toro presents a mythic hero (half human/half demon) seemingly made from the same mold as the classical hero Heracles (Hercules). Hellboy’s modern world is shaped by a cosmology not unlike that of Greek mythology, and as is true for Heracles, his unique pedigree and superior physicality empower him to mediate between the forces of supernaturality and humanity. Hellboy’s experiences evoke comparison with most characters and exploits in the Heraclean mythological corpus; his good character precludes comparison with others. Hellboy must contend with his own versions of Hera, Eurystheus, and a Nemean Lion/Hydra-like monster. He, too, relies on his own superhuman strength, innate cunning and an Athena-like protector to be successful at his job. Both heroes navigate a difficult path to their very different destinies. But in the end, Hellboy’s compassion, humility, unerring moral compass, and genuinely altruistic motivations make him both a better man and a better mythic hero, one worthy even of being loved.

Thus, cognitive psychological models assume an enhanced food attention bias underlying overeating behavior. Nevertheless, this question has only been sparsely investigated so far in younger children and it remains open whether restrained eating behavior plays a correlative role. Methods: The present study investigated this specific information processing bias for food relevant stimuli in 34 overweight children between 6 and 10 years and 34 normal weight children matched for age, sex and socioeconomic status. Children completed a computerized Food Picture Interference task that assessed reaction time interference effects towards high and low calorie food pictures. Level of hunger and restrained eating were assessed via self-report. Results: Results indicated that while finding no group difference in general processing speed or hunger level before the task, overweight children showed a higher attentional bias to food pictures than normal weight children. No effect of caloric density was found. However, surprisingly, the interference effect was negatively related to restrained eating in the overweight group only. Conclusion: The found hypersensitivity for food cues independent of calorie content in overweight children appears to be related to dysfunctional eating, so that future research should consider strategies for attentional retraining.
