In the presence of your absence: The treatment of older families with a cancer patient.

Describes the psychotherapeutic strategies used in treating older couples in which one member has cancer. Structural family therapy was the primary treatment modality. The therapeutic issues reviewed are cancer as a special crisis in the developmental life cycle, styles of coping, aging, and countertransference around aging and death. Case illustrations are presented to exemplify the problems of illness in old age, inflexible response to stress, and mutual withdrawal.

Caveat lectorp.

A. G. Greenwald's (see record 1980-24373-001) analysis of the totalitarian ego presents an unrecognizable picture of men and women. Greenwald's world is one in which intrapsychic conflict has no place in normal people. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Adrenocortical response to hypertonic saline in rats with lateral hypothalamic lesions.

Used plasma corticosterone levels to assess the response to stress induced by ip injections of hypertonic saline in 27 male albino Harlan-Sprague rats with lateral hypothalamic (LH) or sham lesions. Ss with LH lesions displayed a corticosterone response equal to that of normal Ss under basal conditions, after control injections of isotonic saline, and 20 min after injection of hypertonic saline (1.5 M, 1.0 ml/100 g of body weight). The corticosterone response of Ss with LH lesions, however, was significantly less than that of normal Ss 90 min after injection of hypertonic saline when no water was available. With access to water, normal Ss displayed substantial drinking (14.5 ml/90 min), which resulted in a reduction in plasma corticosterone concentrations to a level observed after a control injection of isotonic saline, but the little water ingested by Ss with LH lesions (2.5 ml) had no effect on the pituitary-adrenal system. It is concluded that the failure of Ss with LH lesions to drink following a hydrational challenge is not the result of an exaggerated response to stress.

Elaboration d'un instrument de mesure des habiletés socio-cognitives chez l'enfant de cinq à dix ans.

To assess social cognitive skills in children, a special test was constructed with cognitive and linguistic demands adapted to young children. The test consisted of 4 tasks that were submitted to 200 children, aged 5–10 yrs. Three tasks were devised to measure cognitive role-taking and the 4th to measure referential communication. Results show a significant increase in performance with age for each task and a significant increasing order of difficulty in the tasks. Thus, each task corresponded to specific levels in the development of role-taking skills. (16 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-schemas and gender.

Examined the information processing consequences of self-schemas about gender in 2 studies (467 undergraduates). Systematic differences in cognitive performance were observed among Ss identified as masculine schematics, feminine schematics, low androgynous, and high androgynous (Bem Sex-Role Inventory). Feminine schematics remembered more feminine than masculine attributes, endorsed more feminine qualities, required shorter processing times for "me" judgments to these attributes, were more confident of their judgments, and were able to supply relatively more examples of past feminine than masculine behavior. A parallel pattern of results was found for masculine stimuli in masculine schematics. Androgynous Ss recalled as many masculine as feminine attributes and did not differentiate between masculine and feminine attributes with respect to latency or confidence. Comparison of the 2 groups of androgynous Ss shows that only low androgynous Ss should be considered aschematic with respect to gender.

Structure-activity relationships for chain-shortened analogs of (Z)-5-decenyl acetate,a pheromone component of the turnip moth,Agrotis segetum

Structure-activity relationships for chain-shortened analogs of (Z)-5-decenyl acetate, a pheromone component of the turnip moth,Agrotis segetum, have been studied by electrophysiological single-sensillum technique and interpreted in terms of a previously reported receptor-interaction model. The results indicate that the terminal methyl group, as well as the acetate group, interacts with highly complementary receptor sites. The terminal alkyl chain is suggested to interact with a hydrophobic pocket extending over the two methylene groups closest to the terminal methyl group. The amounts of stimulus actually released from the odor source have been studied. The results demonstrate the necessity to take differences of volatility into account in comparisons of electrophysiological data for compounds of different chain lengths. It is shown that relative vapor pressures may to a good approximation be employed to estimate correction factors.Schiff., Lepidoptera: Noctuidae.     

Triangulation mapping of oxidative bursts released by single fibroblasts by amperometry at microelectrodes

It has been previously established that a lesion created by a microcapillary in the membrane of a single aerobic cell (from skin or immune origin) was sufficient to induce a local membrane depolarization and the ensuing release of oxidative bursts. Their kinetic and quantitative features reveal the activity of cell constitutive enzymes, namely, NADPH oxidases and NO synthases, prone to produce rapidly reactive oxygen and reactive nitrogen species. Until now, the spatial resolution provided by microelectrodes has been exploited in this context to characterize the chemical composition of oxidative bursts at several cell types with high collection efficiency. In the present work, spatial features of the oxidative bursts from single human fibroblasts were investigated using a step-by-step geometrical mapping approach. The spatial locations of cell active zones and of the extent of the activated area, when a cell membrane was stressed by a microcapillary's tip of 1-microm radius, have been addressed. On cells of large dimensions such as fibroblasts, ROS and RNS emission originated from a disk surface of the membrane limited to approximately 15-microm radius around the approximately 1-microm hole created by the microcapillary. This experimental result was rationalized through a simple physicochemical model designed to portray the extent of the membrane activated area due to ion concentration variations resulting from the pinhole channel created across the cell membrane. This is consistent with the fact that the activation of constitutive enzymatic complexes (NOX and NOS) is hypothesized to be a consequence of local variations of ion concentrations such as K(+), Na(+) or possibly Ca(2+). Our results showed that the calculated area near the cell membrane where the ion concentration gradients are significant was equivalent to the area of species release measured experimentally.
