Behavioral science activities at the Centers for Disease Control and Prevention. A selected overview of exemplary programs.

Behavioral research and surveillance activities are conducted across the Centers for Disease Control and Prevention (CDC). This article highlights activities in 4 program areas: violence against women, tuberculosis elimination, HIV prevention, and occupational health. The unique constraints and opportunities of each organization and program focus have shaped the way research has developed in each of these areas. Behavioral scientists also face many common challenges at CDC. Despite the difficulties of integrating behavioral research into an institution that historically has focused on biomedical and epidemiological research, behavioral scientists have made important contributions to public health. Many opportunities remain for psychologists to translate theory and operationalize constructs for use in solving important public health problems.

Improving the oral health of older people: the approach of the WHO Global Oral Health Programme.

The proportion of older people continues to grow worldwide, especially in developing countries. Non-communicable diseases are fast becoming the leading causes of disability and mortality, and in coming decades health and social policy-makers will face tremendous challenges posed by the rapidly changing burden of chronic diseases in old age. Chronic disease and most oral diseases share common risk factors. Globally, poor oral health amongst older people has been particularly evident in high levels of tooth loss, dental caries experience, and the prevalence rates of periodontal disease, xerostomia and oral precancer/cancer. The negative impact of poor oral conditions on the quality of life of older adults is an important public health issue, which must be addressed by policy-makers. The means for strengthening oral health programme implementation are available; the major challenge is therefore to translate knowledge into action programmes for the oral health of older people. The World Health Organization recommends that countries adopt certain strategies for improving the oral health of the elderly. National health authorities should develop policies and measurable goals and targets for oral health. National public health programmes should incorporate oral health promotion and disease prevention based on the common risk factors approach. Control of oral disease and illness in older adults should be strengthened through organization of affordable oral health services, which meet their needs. The needs for care are highest among disadvantaged, vulnerable groups in both developed and developing countries. In developing countries the challenges to provision of primary oral health care are particularly high because of a shortage of dental manpower. In developed countries reorientation of oral health services towards prevention should consider oral care needs of older people. Education and continuous training must ensure that oral health care providers have skills in and a profound understanding of the biomedical and psychosocial aspects of care for older people. Research for better oral health should not just focus on the biomedical and clinical aspects of oral health care; public health research needs to be strengthened particularly in developing countries. Operational research and efforts to translate science into practice are to be encouraged. WHO supports national capacity building in the oral health of older people through intercountry and interregional exchange of experiences.

Cloning and sequencing of cDNA encoding for a human sperm antigen involved in fertilization.

A cDNA encoding for a sperm antigen, designated NZ-2, was cloned and sequenced from human testis cDNA-lambda gt11 expression library by using antibodies to human sperm surface antigens belonging to 14-18 kD molecular regions. These sperm antigens are involved in binding to zona pellucida of the human oocyte. Computer generated translation analysis of 963-bp cDNA yielded an open reading frame (ORF) of 163 amino acids (aa) with first ATG, Met start codon at nucleotide (nt) 335 and the stop codon TAA at nt 824. The NZ-2 cDNA has 335-bp 5' and 139-bp 3' noncoding regions. The translated protein has a calculated molecular weight of approximately 19 kD, and has two casein kinase II (CK-2) sites at aa 94-97 and 149-152, respectively. Extensive computer search in the GenBank, National Biomedical Research Foundation (NBRF), and Swiss database indicates it to be a novel protein, having 99.5% nt sequence similarity, except for the first 40-bp, only with the human bacterial artificial chromosome (BAC) containing cloned human sperm DNA, at position 76935-76009. The in vitro translated product of T3 RNA polymerase by using NZ-2 cDNA digested with XhoI yielded a protein band of approximately 20 kD, indicating it to be sense strand. The in vitro translated product of T7 RNA polymerase by using NZ-2 cDNA digested with NotI did not yield any protein band, indicating it to be antisense strand. The approximately 20 kD protein was recognized specifically by the antisperm IgG, not by the control IgG in the Western blot procedure. Neither antisperm IgG nor control IgG recognized any protein band in the in vitro translation products of the antisense strand. The human genomic DNAs from three different cells/tissues namely, sperm, kidney, and testis when cut by HindIII, and then hybridized with the NZ-2 cDNA probe in the Southern blot procedure, showed restriction fragment length polymorphism (RFLP). The recombinant human sperm NZ-2 antigen may find applications in the development of a contraceptive vaccine, and diagnosis and treatment of infertility in humans.

Proteomic resources: integrating biomedical information in humans.

Recent improvements in high-throughput proteomic technologies have unleashed the potential for generating vast amounts of data. Managing and sharing proteomic data is not an easy task. In this article, we will discuss some of the high-throughput proteomic techniques that are commonly used today. We will also review the major issues in sharing and dissemination of proteomic data and the recent community initiatives to standardize data formats and ontologies. An overview of the web-based resources and databases for analysis of proteomic data is also provided. Integration of disparate proteomic data sources with genomic and transcriptomic data should make systems biology type of approaches feasible in the near future.

Translational research in childhood obesity prevention.

This article explores the state of translational research in childhood obesity prevention. Five phases of translational research and emerging findings from basic science that could be useful in the design of obesity prevention programs are described. Few intervention studies have been published, and these are dominated by Phase 3 trials (efficacy), conducted in school settings, with a limited number of studies finding significant effects on Body Mass Index or adiposity. Cost-benefit analyses are lacking. Research is needed to translate basic science findings into novel interventions (Phases 1 and 2) and to translate programs with known behavior change capability into dissemination trials (Phase 5). Translation can be facilitated by enhanced communication between basic science and prevention science researchers, the development of interventions for underused settings, using novel strategies, support by institutions and funding agencies for translation, and the design of interventions with translation in mind.

[Second Consensus of Granada on pharmacotherapy failure. Cross-cultural translation from Spanish to Portuguese (European)].

The cross-cultural translation from spanish to portuguese (european) of the Second Consensus of Granada on Pharmacotherapy failure has the objective to provide clinicians and researchers, working in drug therapy follow-up, with a working tool translated with the accuracy and the reliability that a biomedical document requires. The common origin of the spanish and portuguese languages emphasizes the need to do a cross-cultural translation. Errors of translation or wrong interpretations can be due to falses cognates. The cross-cultural translation followed three steps: translation, back-translation and review of the translation of the original text of the Second Consensus of Granada on Pharmacotherapy failure. The result was the portuguese version of the Second Consensus of Granada on Pharmacotherapy failure, presented in the annex I.

Protein analysis by mass spectrometry and sequence database searching: tools for cancer research in the post-genomic era.

The post-genomic era is characterized by the deposition of sequence information for entire genomes in databases. Currently, besides the protein sequences for known human proteins, there are partial sequences from thousands more human proteins for which no biological function has been assigned. A powerful new tool for the unambiguous identification and characterization of gel-separated proteins is accomplished by the combination of mass spectrometry and sequence database searching. This combination provides the cancer biologist with the ability to (i) identify the potential protein:protein associations and (ii) fully characterize function-critical post-translational modifications, both directly from silver-stained polyacrylamide gels. In this report we describe the application of tandem mass spectrometry and database searching to two problems which are prototypical for cancer research and indeed for biomedical research in general. The first is the identification of gel-separated, low abundance proteins based on amino acid sequence composition following coimmunoprecipitation with the human apoptosis inhibitor protein BclX(L). The second is the determination of the precise sites of phosphorylation of the human regulatory protein 4E-BP1, which controls mRNA translation.

Proteomics.

The genome sequences of important model systems are available and the focus is now shifting to large-scale experiments enabled by this data. Following in the footsteps of genomics, we have functional genomics, proteomics, and even metabolomics, roughly paralleling the biological hierarchy of the transcription, translation, and production of small molecules. Proteomics is initially concerned with determining the structure, expression, localization, biochemical activity, interactions, and cellular roles of as many proteins as possible. There has been great progress owing to novel instrumentation, experimental strategies, and bioinformatics methods. The area of protein-protein interactions has been especially fruitful. First pass interaction maps of some model organisms exist, and the proteins in many important organelles are about to be determined. Researchers are also beginning to integrate large-scale data sets from various "omics" disciplines in targeted investigations of specific biomedical areas and in pursuit of a general framework for systems biology.

Microarray profiling of antiviral antibodies for the development of diagnostics, vaccines, and therapeutics.

Multiplex analysis of antiviral antibody (Ab) responses provides a potentially powerful strategy for viral diagnosis, prognostication, and development of vaccines and prophylactic Abs. In the coming years, advancements in proteomic technologies will provide even more robust methods to characterize antiviral Ab responses. Biomedical researchers will be faced with the exciting challenge of identifying antiviral Ab specificities that correlate with improved outcomes and efficacious interventions, and translating the findings into more effective diagnostics, prophylactics, and therapeutics.

The xenotransplantation narratives of nine type 1 diabetic patients with renal failure.

Within the research project ''Treatment of Diabetes by Transplantation of Porcine Islets'' that was run by the Swedish Xenoislet Transplantation Network between 1998 and 2003, a partner project called ''Cultural Perspectives on Xenotransplantation'' investigated attitudes toward xenotransplantation development among the patients and their relatives as well as the medical personnel at a transplantation clinic in Sweden. In-depth interviews were done with 37 individuals: nurses, doctors, researchers, patients, and relatives. All interviews were taped and transcribed verbatim. In this presentation the interviews with the nine type 1 diabetic patients with renal failure that took part in the project are focused. The personal and embodied narratives of these nine patients illustrate the ambivalent situation of individuals who are both patients and (potential) experimental subjects simultaneously. Both as actual practice and as biomedical information xenotransplantation research triggers a certain kind of cultural identity of the chronically ill patients--an identity related to how the patients ''translate'' scientific information and, at the same time, counter risk and uncertainty as well as promises of remedy. A central dimension in this cultural identity is a positive but still reluctant embodied attitude toward what spearhead science can bring about.

Translating cell biology into therapeutic advances in Alzheimer's disease.

Studies of the molecular basis of Alzheimer's disease exemplify the increasingly blurred distinction between basic and applied biomedical research. The four genes so far implicated in familial Alzheimer's disease have each been shown to elevate brain levels of the self-aggregating amyloid-beta protein, leading gradually to profound neuronal and glial alteration, synaptic loss and dementia. Progress in understanding this cascade has helped to identify specific therapeutic targets and provides a model for elucidating other neurodegenerative disorders.
