On the efficacy of psychoanalysis.

In this study we critically review the formal research literature pertinent to the outcomes of psychoanalysis and the factors influencing these outcomes. Our inquiry was conducted from a psychoanalytic perspective. We found the research yield consistent with the accumulated body of clinically derived psychoanalytic knowledge, e.

Foot-and-mouth disease and its antigens.

Many factors combine to make foot-and-mouth disease (FMD) one of the most damaging and intractable disease of animals. These include its extreme contagion, wide geographic distribution, great multiplicity of both susceptible animal hosts and viral serotypes, a relatively short duration of immunity to a given serotype and a post-recovery carrier state of the virus in many animal species (e.g.

On the concept of analyzability.

Much of our understanding of analyzability is based upon a model of inquiry that assumes a relative comparability among analysts as observing and influencing instruments. This paper suggests that the individuality in understanding and application of the psychoanalytic procedure inherent in the psychoanalytic enterprise raises questions about the comparability of clinical observation and data and must be taken into account in a realistic understanding of the factors that govern analyzability.

Recombinant DNA technology for the preparation of subunit vaccines.

Recombinant DNA technology appears to be on the verge of producing safe and effective protein vaccines for animal and human diseases. The procedure is applicable to most viruses because their isolated surface proteins generally possess immunogenic activity. Strategies used for the preparation and cloning of the appropriate genes depend on the characteristics of the viral genomes: whether DNA or RNA; their size, strandedness, and segmentation; and whether messenger RNA are monocistronic or polycistronic.

Foot-and-mouth disease virus: immunogenicity and structure of fragments derived from capsid protein VP and of virus containing cleaved VP.

Peptide fragments were obtained from the immunogenic capsid protein VP3, ca. 24 kilodaltons (kd), of foot-and-mouth disease virus type A12 119ab by three procedures: (1) spontaneous proteolysis of in virion VP3 in tissue cultures to produce a 15 kd peptide, designated S fragment; (2) trypsin treatment of purified virus to produce a 16 kg peptide, designated T fragment; and (3) cyanogen bromide cleavage of purified VP3 to produce a 13 kd fragment. Following isolation and purification by gel electrophoresis, VP3 and each of the three fragments were immunogenic for livestock.

Cloned viral protein vaccine for foot-and-mouth disease: responses in cattle and swine.

A DNA sequence coding for the immunogenic capsid protein VP3 of foot-and-mouth disease virus A12, prepared from the virion RNA, was ligated to a plasmid designed to express a chimeric protein from the Escherichia coli tryptophan promoter-operator system. When Escherichia coli transformed with this plasmid was grown in tryptophan-depleted media, approximately 17 percent of the total cellular protein was found to be an insoluble and stable chimeric protein. The purified chimeric protein competed equally on a molar basis with VP3 for specific antibodies to foot-and-mouth disease virus.

Identification of a protein kinase activity in purified foot- and-mouth disease virus.

Purified preparations of foot-and-mouth disease virus types A, O, and C contain a protein kinase activity which can transfer the gamma phosphate of [32P]ATP to virion structural proteins VP2 and VP3 and exogenous acceptor proteins. Utilizing protamine sulfate as an acceptor, the kinase activity can be demonstrated in disrupted virus but not in intact virus. The enzyme is heat labile with optimal activity at pH 7 or greater.

Units of observation and perspectives on the psychoanalytic process.

Over the past quarter century, brief segments of tape-recorded psychotherapy have become the most widely employed unit for the empirical investigation of the psychotherapeutic process. Our aim was to see how judgements based upon brief segments of tape-recorded psychoanalysis corresponded with judgements based upon the hours from which they were taken. Seven experienced psychoanalysts independently made clinical and quantitative judgements about 29 treatment-related variables on 24 five-minute segments excerpted from psychoanalytic sessions and on the 12 whole sessions from which they were taken.

The structural polypeptides of aphthovirus are phosphoproteins.

Analysis of aphthovirus A12, strain 119ab, grown in the presence of inorganic 32P revealed that two of the major viral polypeptides, VP4 and trypsin-sensitive protein VP3, were highly phosphorylated. The other major polypeptides, VP1 and VP2, were also phosphorylated but to a much lesser extent. Polypeptides VP0 and P56, of which there are approximately one of two copies per aphthovirion, were also labeled with 32P.

Predicting the outcome of psychotherapy. findings of the Penn Psychotherapy Project.

Our study of predictability of outcomes of psychotherapy used predictions of two kinds: (1) direct predictions by patients, therapists, and clinical observers; and (2) predictive measures derived from the same sources. Seventy-three nonpsychotic patients were treated in psychoanalytically oriented psychotherapy (mean, 44 sessions). Two thirds of the therapists were residents in psychiatry; one third were more experienced.

Caliciviridae.

The caliciviruses, as a proposed family Caliciviridae, have a distinct virion morphology with cup-shaped depressions on a spherical capsid surface. The viruses have single-stranded RNA, which has a molecular weight about 2.6 x 10(6) and is infectious.

Preconditions and consequences of transference interpretations. A clinical-quantitative investigation.

Our aim was to study the preconditions and consequences of transference interpretations by both quantitative and clinical methods. We selected the three specimen psychoanalytic treatments which had been studied most by clinical-quantitative research. For each patient the main data consisted of 16 interpretation contexts.

Foot-and-mouth disease virus immunogenic capsid protein VPT: N-terminal sequences and immunogenic peptides obtained by CNBr and tryptic cleavages.

The immunogenic capsid protein (VPT), circa 30 kiladaltons (kd), of foot-and-mouth disease virus was examined for (i) its ability to induce neutralizing antibody in guinea pigs after chemical modifications and CNBr or tryptic cleavages and (ii) N-terminal amino sequence homology across three virus types. The immunogenicity of VPT was inactivated by glutaraldehyde treatment, carboxymethylation and maleylation or citraconylation. However, de-citraconylation restored part of the lost activity.

Effect of zinc and other chemical agents on foot-and-mouth-disease virus replication.

Chemical agents reported to inhibit the growth of various ribonucleic acid and deoxyribonucleic acid viruses were tested against foot-and-mouth disease virus in cell culture. These included Zn(2+), aurintricarboxylic acid, polyribocytidylic acid, polyriboinosinic acid, phosphonoacetic acid, and the viral contact inactivator N-methyl isatin beta-thiosemicarbazone alone and with CuSO(4). The most effective agent, Zn(2+), inhibited foot-and-mouth disease virus production in primary calf kidney cells by 1 log unit at 0.
