Wild-type alternatively spliced p53: binding to DNA and interaction with the major p53 protein in vitro and in cells

A p53 variant protein (p53as) generated from alternatively spliced p53 RNA is expressed in normal and malignant mouse cells and tissues, and p53as antigen activity is preferentially associated with the G2 phase of the cell cycle, suggesting that p53as and p53 protein may have distinct properties. Using p53as and p53 proteins translated in vitro, we now provide evidence that p53as protein has efficient sequence-specific DNA-binding ability. DNA binding by p53 protein is inefficient in comparison and requires activation. Furthermore, p53as and p53 proteins formed hetero-oligomers when co-translated in vitro, resulting in inactivation of p53as DNA-binding activity. Gel filtration indicated that p53as translated in vitro, like p53, formed tetramers. In support of a functional role of p53as in cells, p53as/p53 hetero-oligomers were coimmunoprecipitated from mouse cells, and both protein forms were detectable in nuclear extracts by electrophoretic mobility shift assays. These results suggest that the biochemical functions of p53 are mediated by interaction between two endogenous protein products of the wild-type p53 gene.     

Renal ATPases twenty-four hours after uninephrectomy: the role of IGF-1

The purpose of this article is to discuss the concept and phenomenon of intuition in nursing. With an overview of theories of intuition in philosophy and empirical research as the starting point, the authors discuss the conceptualization of intuition in nursing. Concept analyses, intuition as phenomenological nursing knowledge, intuition as clinical knowledge and intuition as spiritual connection are discussed. The authors conclude that the conceptions of intuition in nursing differ with respect to their philosophical underpinnings and that it can be questioned whether 'intuition' is always a proper term for the kind of knowledge investigated. Intuition is seen as an important concept in nursing, but there are still philosophical as well as empirical and practical problems to investigate.     

Methods to assess iron status in various NHANES surveys

This paper summarizes iron status measurements included in the three cross-sectional National Health and Nutrition Examination Surveys (NHANES) completed to date, as well as a special study of Hispanics, known as the Hispanic Health and Nutrition Examination Survey (HHANES). Approaches for defining iron status in the population based on these measurements are also described as well as issues in comparing iron status data between surveys, using NHANES II and III data as an example.     

Sparing of patterned alternation but not partial reinforcement effect after infant and adult hippocampal lesions in the rat.

Assessed the effect of hippocampal lesions in patterned (single) alternation (PSA) and the partial reinforcement extinction effect (PREE), the 2 reward-schedule effects that appear earliest in ontogeny. 147 Sprague-Dawley rats received hippocampal or sham lesions or served as unoperated controls. Three groups were tested for each effect: lesion as infant/test as infant; lesion as infant/test as adult; and lesion as adult/test as adult. Hippocampal lesions had no effect on PSA in any of the 3 conditions except for a suggestion that the effect was mildly attenuated in Ss given lesions as infants and tested as adults—Ss were able to discriminate rewarded from nonrewarded trials and to inhibit responding on nonrewarded trials. On the other hand, the PREE was eliminated under all conditions of testing, in each case because of an increase in persistence following continuously reinforced acquisition. Results are discussed in terms of the functional maturation of the hippocampus and a possible dissociation of mechanisms that mediate response suppression in PSA and in the PREE in infant rats.

Disease assessment and management of the vasculitides

The improvement in survival with chemotherapy has resulted in a change of the natural history of the systemic vasculitic syndromes. The vasculitides are now viewed as chronic disease rather than fatal conditions. Their course is frequently characterized by relapse as well as the scars of irreversible organ damage from disease and drug toxicity. Assessment tools are available which can serve as outcome measures in clinical trials as well as a guide to better management of individual patients. Improvements in therapy in future are dependent on a better understanding of the pathogenesis of these conditions and the ability to assess disease accurately.     

The role of the psychologist in the disability evaluation of emotional and intellectual impairments under the social security act.

"Psychological examinations are frequently required for the evaluation of emotional and intellectual impairments in order to establish the degree of loss of function in workers who apply for disability benefits as well as in adults who are disabled in childhood… . The presence of severe and persistent illness should be associated with objective evidences of regression substantial enough to preclude vocational activity… . Psychological evaluations serve to pinpoint the specific functional capacities of the applicant so as to serve as a basis for the evaluation as well as for rehabilitation."

New species of Aeromonas isolated in Cuba

One hundred and fifty-five strains of Aeromonas isolated in the stools of children under 5 years presenting with acute diarrheal disease were studied. Using the Aerokey II system for the identification of species, 47 strains were identified as Aeromonas caviae, 58 as Aeromonas hydrophila, 23 as Aeromonas veronii biovar sobria, 14 as Aeromonas trota, 9 as Aeromonas veronii biovar veronii, 2 as Aeromonas jandaei and 2 as Aeromonas shubertii, Emphasis is placed on the advantages of this method which allowed for the classification of new species not identified previously in our country.     

Decreased oral colonization of Streptococcus mutans during aging of Sprague-Dawley rats

The colonization by streptomycin-resistant Streptococcus mutans strains of the teeth of conventional and ex-germfree Sprague-Dawley rats of various ages fed either a high-sucrose or a high-glucose diet was studied. Bacterial colonization occurred with increasingly greater difficulty as the rats became older. This was observed in studies of the implantation of the test organism after oral inoculation with different cell numbers as well as its transmission between infected and uninfected rats. With rat fed sucrose diet, the effect of age could not be demonstrated until they were age 3 months or older; the results from rats fed a glucose diet suggest that changes may already have occurred early after weaning. Changes in susceptibility to colonization during aging manifested themselves as a decrease in the proportions of rats which became infected as well as lower population levels in infected rats. The possible mechanism(s) involved as well as the possible significance of the findings was discussed.     

Molt induction in lobsters (Homarus americanus) by intramuscular injection of ecdysterone triacetate

The principal component of the successful, molt-inducing ecdysterone acetate mixture was established as ecdysterone triacetate and shown to have the same activity as the acetate mixture. The triacetate induced ecdysis in male lobsters collected in winter and summer and in female lobsters collected in winter. Intramuscular injections of triacetate in ethanol were as effective as those with oil emulsions.
