Temperament and character in italian men with anorexia nervosa: a controlled study with the temperament and character inventory.

This study compares personality traits of men and women with anorexia nervosa and matched controls. The Temperament and Character Inventory was used to assess personality traits of 15 male and 50 female anorectics and 28 male and 58 female controls matched for age and education. Male anorectic patients displayed overall lower reward dependence and cooperativeness. Male and female anorectics displayed higher persistence and lower self-directedness than controls. Anorectic men had lower harm avoidance than anorectic women. Discriminating analysis revealed the anorectic male group as the most clearly defined. Anorectic men shared more traits with anorectic women than with male controls. Temperament and character of anorectic men reflect features partly similar to those of women with anorexia. Personal history and discriminating analysis led to interesting inferences about the gender identity of anorectic men. These results should be helpful in directing pharmacologic and psychotherapeutic approaches that consider the specific personality traits of these patients.

Facial pain. II. A prospective survey of 1052 patients with a view of: character of the attacks, onset, course, and character of pain.

The material, definition, delimitation, and classification of facial pain, general data, hereditary conditions, and previous diseases have been discussed in a preceding study. According to the character of the attacks the material has been classified into TTN = Typical Trigeminal Neuralgia (1/4), ATN = Atypical Trigeminal Neuralgia (1/4), and NNFP = Non-neuralgiform Facial Pain (1/2). The typical Trigeminal Neuralgia is a transitory, shooting pain, well defined. The other two groups are less well defined. The patients come to be treated by specialists 1-5 years after the onset of pain. The oral cavity is often perceived as the origin of the pain. A systematic examination shows that demonstrable pathological diseases in the masticatory organs are rarely connected with the pain condition. Dental treatment has provided poor results. Facial pain is a very constant phenomenon which does not- or only to a negligible degree--change over an agelong course. In the present material 8 characters of pain are used: Shooting-cutting, boring, squeezing-pressing, throbbing-hammering, dull, burning-smarting, prickling-sticking, paraesthetic. With the exception of a few cases of apoplexy and herpes zoster there is no pain reaction which can be referred to on an aethilogical basis.

Hydrophobic character of surface regions and total hydrophobicity of four variants of chromosomal class C beta-lactamase from Pseudomonas aeruginosa are identical. Chromatographic comparison of the hydrophobic character of the variants and the effect of focusing buffer composition on the separation of the variants by chromatofocusing with internal and external pH gradients.

The hydrophobic character of class C beta-lactamase molecular variants from Pseudomonas aeruginosa was compared by hydrophobic interaction chromatography and reversed-phase liquid chromatography, respectively. Separation of the variants by hydrophobic interaction chromatography was not achieved by modifying salt and pH of mobile phases. Reversed-phase liquid chromatography of the variants resulted in almost identical retention times. The results showed that the hydrophobic character of surface regions as well as total hydrophobicity of the variants are identical. The resolving power of external, internal and gradient chromatofocusing of the variants on strong and weak anion exchangers using low-molecular-mass buffers was compared to that of commercial ampholytes and showed no difference in separation pattern of the variants. Comparisons of variant isoelectric point (pI) values determined by chromatofocusing and isoelectric focusing showed that pI values determined by gradient chromatofocusing were most similar to the pI values determined by isoelectric focusing.

The echinoderm immune system. Characters shared with vertebrate immune systems and characters arising later in deuterostome phylogeny.

In summary, the characters of the echinoderm immune system that we review here can be considered to illuminate the baseline nonadaptive immune systems that were our original deuterostome heritage. We still retain--and greatly rely upon--similarly functioning, nonadaptive cellular defense systems. It is worth stressing that sea urchins are long lived, normally healthy animals that display remarkable abilities to heal wounds and combat major infections. From an external point of view, their immune systems obviously work very well. Thus, their cellular defense systems are extremely sensitive, and they respond rapidly to minor perturbations, all without any specific adaptive capabilities. These systems probably function through the transduction of signals conveying information on injury and infection, just as do the equivalent systems that underlie and back up our own adaptive immune systems, and that provide the initial series of defenses against pathogenic invasions. Many extremely interesting questions remain regarding the evolution of the deuterostome immune response. Are the echinoderm and tunicate systems the same, or have the protochordates augmented the basic phagocyte system with an as yet unidentified chordate-like character? Do the jawless fishes produce Igs that would make them similar to the sharks, or are they vertebrates without an Ig system that essentially rely on an invertebrate-like, nonspecific, activated phagocyte type of immune system? How do sharks regulate their immune system without T cells and MHC class I? How do they avoid producing autoantibodies? Future research will not only answer these questions, but those answers will also be enlightening with regard to the origins of the mammalian immune system in which ancient functions and subsystems remain.

Establishing character correspondence for sensory organ traits in flies: sensory organ development provides insight for reconstructing character evolution.

In Diptera and in other insects sensory organ patterns play an important role in the construction of phylogenies based on morphological characters. In this paper I explore the developmental basis for sensory organ pattern transformations between and within species. Knowledge of the properties of sensory organ development provides a foundation to judge the correspondence relationships between sensory organs. This is used to explore what components of notum bristle patterns are equivalent across the Schizophora. By investigating patterning processes in leg development, and their conservation across holometabolous insects, I show ways of relating specialised leg vestiture between species. Sensory organ patterns on the legs are diversified under homeotic gene control, potentially adding patterns of homeotic variation between legs to the list of informative traits for phylogenetic analysis. Correspondence relationships between wing and haltere sensory organ fields are resolved by exploring homeotic gene action in detail.

[Contribution towards the study of the average visual-evoked response; non-gaussian character of spontaneous electroencephalographic activity; non-independence of noise and signal; possible non-stationary character of evoked response (author's transl)].

The succession of amplitudes constituting spontaneous electroencephalographic activity cannot be regarded as a strictly normal distribution. Spontaneous activity and the evoked response are not independent. The signal (evoked response)is, in some cases, non-stationary. The average visual-evoked response comprises several successive temporal fragments of which the stationary character varies. This variability of the average visual-evoked response argues in favour of the complexity of its genesis.

[Directed character of genetic variation during long-term selection of Drosophila melanogaster strains for adaptively important characters].

Related fly strains that were selected for differences in reproductive function for about 700 generations were studied. The low-active (LA) strain differs from other related and highly active strains of interest at a set of characters. Qualitative differences in the spectrum of viability mutations are retained in strains selected in opposite directions. Low-active strains carry a great number of deleterious mutations. Such mutations are rare in the related highly active strains. Moreover, about 50% of chromosomes in the highly active strains carry supervital mutations, which increase viability. Recombination analysis showed the presence of at least several viability mutations in each chromosome of the strains studied. Unlike highly active strains, the low-active ones are characterized by an extremely high spontaneous mutation rate. The conservation of genetic heterogeneity observed in long-term selected strains, as well as the high mutation rate, must be connected with regular changes in the spectrum of retrotransposons (MDG1, MDG3) and hobo elements characteristic of the strains studied. A special crossing system that induces a sharp increase in LA induction potential in the H-E system of hybrid dysgenesis was developed.

A character in search of character: Narcissistic Personality Disorder and Ego State Therapy.

The individual diagnosed with Narcissistic Personality Disorder presents with grandiosity, extreme self-involvement, and lack of interest in and empathy for others. This paper reviews current theories concerning the development and treatment of Narcissistic Personality Disorder, and introduces the use of Ego State Therapy for its treatment. The ego state model of treatment will be described and demonstrated with case material. Initially ego states that reveal the grandiosity will be accessed. As therapy progresses, ego states that hold the underlying feelings of emptiness, rage, and depression are able to emerge. With further treatment, transformation and maturation of the ego states occur, reflecting the changes in internal structure and dynamics as well as improvement in external interpersonal relationships. Issues concerning Ego State Therapy as utilized with personality disorders will be discussed and contrasted with more traditional methods of treatment.
