Abstract
The present study examined the difference between young people who terminated treatment prematurely and who continued in treatment. One hundred and thirty-four young people (ages 12 to 24 years) who attended a community-based psychotherapy centre for psychoanalytic psychotherapy between 1 April 1993 and 31 March 1996 comprised the sample. It was predicted that drop-outs would consist of younger adolescents who were referred, who show a high score for externalizing problems such as aggression and delinquency and a low score for internalizing problems such as anxiety and depression. It was also predicted that continuers would be older, self-referred and show a high score for internalizing problems and a low score for externalizing problems. The results indicated significant differences between drop-outs and continuers: drop-outs were younger, had greater externalizing problems, school problems and presented with moderate to severe hyperkinetic or conduct disorder. Continuers were older, had fewer externalizing problems, were self-referred and were likely to be treated by supportive therapists. Since age was the most significant predictor of attendance, the sample was separated into younger adolescents and older adolescents and the same analyses repeated. In the younger group ethnic minority status, and being treated by a supportive therapist predicted continuing in treatment and a diagnosis of conduct disorder predicted premature termination. The clinical implications of the present findings for the delivery of psychotherapy services to young people are discussed.

Abstract
We have identified an RNA-specific adenosine deaminase (termed Tad1p/scADAT1) from Saccharomyces cerevisiae that selectively converts adenosine at position 37 of eukaryotic tRNAAla to inosine. The activity of purified recombinant Tad1p depends on the conformation of its tRNA substrate and the enzyme was found to be inactive on all other types of RNA tested. Mutant strains in which the TAD1 gene is disrupted are viable but lack Tad1p enzyme activity and their tRNAAla is not modified at position A37. Transformation of the mutant cells with the TAD1 gene restored enzyme activity. Tad1p has significant sequence similarity with the mammalian editing enzymes which act on specific precursor-mRNAs and on long double-stranded RNA. These findings suggest an evolutionary link between pre-mRNA editing and tRNA modification.

Abstract
ADAR1 and ADAR2 are members of a family of enzymes that catalyze the conversion of adenosine to inosine in double-stranded RNA. Unlike the other types of RNA editing that involve multiprotein editing complexes, the site-specific deamination of an adenosine to inosine is catalyzed by single enzymes. ADAR1 and ADAR2 have been purified and the genes cloned from various sources. Each gene encodes multiple splice variants. As it is crucial to have an adequate supply of pure protein to investigate this type of RNA editing, we describe in this article methods for both the purification and the overexpression of either full-length or partial ADAR1 and ADAR2 isoforms.

Abstract
OBJECTIVE Phagocyte-derived reactive oxygen species (ROS) are involved in microbicidal activities as well as in tissue damage at sites of inflammation. Carotenoids play an important function in protecting cells from oxidant damage. We investigated the in vitro and in vivo effect of 13-cis and 9-cis-beta-carotene on human neutrophils. METHODS Neutrophils from healthy donors in the presence of 0.25 mumol/L-1 mumol/l beta-carotene and from subjects under beta-carotene supplementation and UVA or UVA/B exposure were stimulated by opsonized zymosan and the generation of ROS was measured by electron spin resonance spectroscopy. RESULTS Our in vitro results show different effects of the two isomers on stimulated neutrophils. 9-cis-beta-carotene did not produce any change, whereas 13-cis-beta-carotene significantly and concentration-dependent inhibited the ROS generation by stimulated neutrophils. Further, in a controlled study, we were able to demonstrate an in vivo protective effect of beta-carotene on neutrophils against UVA damage by beta-carotene supplemented subjects.

Abstract
OBJECTIVE To study the potential efficacy of retinoids on granulocytes with regard to their role in inflammatory dermatoses. METHODS We investigated the in vitro effect of acitretin and isotretinoin on the generation of reactive oxygen species (ROS) by stimulated human neutrophils using EPR spin trapping techniques. RESULTS The effects of the two retinoids on ROS generation by neutrophils were different. Acitretin increased the generation of hydroxyl radicals, whereas isotretinoin showed an antioxidant activity against the superoxide anion. CONCLUSIONS Our study demonstrates retinoid type-dependent effects on ROS production by stimulated neutrophils.

Abstract
The double-stranded RNA-specific editase 1 (RED1/ADAR2) is implicated in the editing of precursor-mRNAs (pre-mRNA) encoding subunits of glutamate receptors (GluRs) in brain. Site-specific deamination of adenosine to inosine alters the codon at the Q/R site in GluR-B rendering the heteromeric receptor impermeable to Ca2+ ions. We cloned human RED1 (hRED1/hADAR2) cDNAs from a brain cDNA library. The human enzyme is 95% identical to the rat homologue. We characterized two alternatively spliced forms that differed by the presence of an Alu-J cassette in the deaminase domain. For the long form containing the Alu cassette, we isolated cDNA clones with an alternative C-terminus and 3'-UTR. An 8.8-kb transcript of hRED1 is most abundant in brain and heart, and lower levels are detected in other tissues. In vitro editing assays with purified recombinant hRED1 containing or lacking the Alu-J cassette revealed that both forms of the protein have the same substrate specificity, but differ in their catalytic activity.

Abstract
The relation of patterns of attachment and psychiatric status was studied in 82 nonpsychotic inpatients and 85 case-matched controls using the Adult Attachment Interview (AAI). AAI transcripts rated (masked to case vs. control status and treatment) were classified using M. Main and R. Goldwyn's (1991) system. Psychiatric patients, diagnosed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.) I and II structured interviews, were more likely to be classified as preoccupied and unresolved with respect to loss or abuse. On Axis I, anxiety was associated with unresolved status, and AAI scales were able to discriminate depression and eating disorder. On Axis II, borderline personality disorder (BPD) was linked to experience of severe trauma and lack of resolution with respect to it. BPD patients were also rated significantly lower on a scale measuring awareness of mental states. Preliminary outcome results suggest that individuals rated as dismissing on the AAI are more likely to show improvements in psychotherapy.

Abstract
RNAs encoding subunits of glutamate-gated ion channel receptors are posttranscriptionally modified by RNA editing and alternative splicing. The change in amino acid sequence caused by RNA editing can affect both the kinetics and the permeability of the ion channel receptors to cations. Here, we report the purification of a 90-kDa double-stranded RNA-specific adenosine deaminase from HeLa cell nuclear extract that specifically edits the glutamine codon at position 586 in the pre-mRNA of the glutamate receptor B subunit. Site-specific deamination of an adenosine to an inosine converts the glutamine codon to that of arginine. Recently, a gene encoding a double-stranded-specific editase (RED1) was cloned from a rat brain cDNA library. Antibodies generated against the deaminase domain of its human homolog specifically recognized and inhibited the activity of the 90-kDa enzyme, indicating that we have purified hRED1 the human homolog of rat RED1. This enzyme is distinct from double-stranded RNA-specific adenosine deaminase which we and others have previously purified and cloned.

Abstract
Infectious complications are the leading cause of death in acute pancreatitis. Individual factors of immune defence could be of significance, whether or not a patient develops a severe course with infectious complications. In a prospective 5-year trial including 72 patients, we investigated 29 cellular and humoral markers of the body's defence system for their potential to indicate the severity and course of acute pancreatitis. Complement factors C3 and C4 as well as immunoglobulins IgG, IgM and IgA were normal, in general. Measurable levels of IL-1 alpha, IL-1 beta, IL-2 and sIL-2R could be detected only occasionally. Values of alpha 1-AT, TNF-alpha, TNF alpha-Rp75, neopterin, sICAM-1, IL-8, IL-1RA and sIL-6R did not correlate with a severe course. Due to the high magnitude of increase, CRP, IL-6 and granulocyte elastase were the best indicators of the inflammatory process. Delayed-type hypersensitivity response was the only early predictor of a severe course. It was superior over other cellular markers such as monocyte count or CD4+/CD8+ ratio. In vitro function of polymorphonuclear granulocytes (PMN) was not adequate to the severity of the disease already during the first week of illness. During further course, PMN motility and capacities to produce reactive oxygen species even worsened. The compromized PMN function could explain the frequent development of infectious complications in patients suffering from severe pancreatitis. These results should encourage new concepts of infection prophylaxis using stimulants of cellular defence.

Abstract
Treponema pallidum, the etiological agent of syphilis, is characterized by a paucity of surface exposed outer membrane proteins and a high content of cytoplasma membrane associated lipoproteins. At all stages of infection intense antibody responses against lipoproteins are detectable. In order to provide antigens for syphilis diagnosis the highly immunogenic lipoproteins TpN17, TpN29-35 (TpD), TpN44.5 (TmpA), TpN47, and TpN35 (TmpC) and the membrane protein TpN39 (BMP) were cloned. Insertion of PCR amplified DNA into an E. coli expression vector resulted in high level expression of antigens. N-terminal hexahistidine sequence allowed efficient purification of fusion proteins by metal chelate affinity chromatography. The recombinant antigens were tested in enzyme-linked immunosorbent assays. TpN17, TpN47, and TpN44.5 antigens showed high antibody titers. Assays with the three antigens combined resulted in a further improvement of diagnostic sensitivity in comparison with single antigens. Antibodies were found in 17 of 18 patients in all stages of syphilis, whereas 42 normal human sera were nonreactive. No cross-reactivity was detected in 24 sera of patients with Lyme borreliosis.

Abstract
Bone mineral density (BMD) and bone mineral content (BMC) were measured using DXA at lumbar spine and tibial diaphyses at the beginning and at the end of a 15-week training period in 151 military recruits of the Swiss army belonging to 5 different troop categories (infantry grenadiers, tank drivers, tank gunners, signalmen, and privates) who each were exposed to physical training of various intensity. At baseline, height, body mass index, and degree of physical fitness independently correlated with vertebral and tibial BMD. Over the 15 weeks of physical training BMD at tibial diaphyses increased by 2.2 +/- 0.3% at the left leg (p = 0.0001) and by 1.1% at the right leg (p = 0.002) with differences between troop categories. At lumbar spine, BMD decreased significantly in tank drivers (-1.2 +/- 0.4%, p = 0.001) and particularly in infantry grenadiers (-2.1 +/- 0.4%) who had the most strenuous weight-bearing training, but not in other troop categories. This decrease was twice as large at the center of the vertebra than for the whole vertebra. These BMD changes were associated with increments in serum levels of osteocalcin and alkaline phosphatase activity. From the initial cohort, 48 subjects volunteered for a third investigation carried out 2 years after the end of the military training period. At this time, lumbar BMD and BMC had risen back to baseline, whereas at tibial diaphyses bone width and BMC but not BMD increased by 5.8 +/- 1.1% and 6.2 +/- 0.9%, respectively, vs. baseline (p = 0.0001 for both).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The need for an alternative mailbag to the conventional U.S. postal mailbag, which hangs at the side over one shoulder, was investigated. Based on the results of a pilot study, two types of alternative mailbags, both including waist support and one that splits the load into two parts, are recommended. The metabolic energy requirement and lateral trunk muscle fatigue resulting from the use of the alternative mailbags were compared with those resulting from the conventional U.S. postal mailbag. The alternative mailbags resulted in no significant change in metabolic load. Both alternative mailbags resulted in significantly less lateral trunk muscle fatigue. It is proposed that this reduction in fatigue would result in reduced musculoskeletal stress and reduced potential for back injury.

Abstract
The purpose of this project was to verify the value of perfused periosteum as a possibly ideal bed for autogenous cancellous bone graft. The model consisted of a 7 cm defect in the sheep tibia, stabilized with a locked intramedullary nail. The defect was filled with conventional cortico-cancellous bone graft covered either with a muscle or a perfused osteoperiosteal flap. The incorporation of the graft was analysed by a series of radiological and mechanical examinations. The graft embedded in perfused osteo-periosteum was rapidly remodelled to a strong, circular bone. Mechanical testing revealed even better values than for normal bone. The graft embedded in muscle showed an important resorptive phase before scanty, incomplete, reconstitution of bone appeared. Mechanical properties were poor. The study supports the hypothesis that perfused osteo-periosteum is an ideal bed for cancellous bone graft and that perfused muscle is not the ideal environment for incorporation of the graft.
