1. Synthesis and antimicrobial evaluation of two peptide LyeTx I derivatives modified with the chelating agent HYNIC for radiolabeling with technetium-99m
Abstract Background Current diagnostic methods and imaging techniques are not able to differentiate septic and aseptic inflammation. Thus, reliable methods are sought to provide this distinction and scintigraphic imaging is an interesting option, since it is based on physiological changes. In this context, radiolabeled antimicrobial peptides have been inve

2. Diagnostic work-up of gastroenteropancreatic neuroendocrine tumors
Neuroendocrine tumors are a heterogeneous group of malignancies that present a diagnostic challenge. The majority of patients (more than 60%) present with metastatic disease at diagnosis. The diagnosis is based on histopathology, imaging, and circulating biomarkers. The histopathology should contain specific neuroendocrine markers such as chromogranin A, syn

3. Alta eficiência diagnóstica do teste IgM-ELISA utilizando múltiplos antígenos peptídicos (MAPs) de T. gondii (ESA SAG-1, GRA-1 e GRA-7) na diferenciação de formas clínicas da toxoplasmose / High diagnostic efficiency of IgM-ELISA with the use of multiple antigen peptides (MAPS) from T. gondii ESA (SAG-1, GRA-1 AND GRA-7 in acute toxoplasmosis
Os principais marcadores sorológicos para o diagnóstico da toxoplasmose aguda ou recente são os anticorpos IgM específicos e anticorpos IgG de baixa avidez. Entretanto em alguns pacientes, anticorpos IgM e baixa avidez de anticorpos IgG podem persistir, ultrapassando o período da fase recente aguda contribuindo para erros de interpretação diagnóstica

4. Uso de espectrometria de massas e mobilidade iônica na caracterização de peptídeos provenientes de experimentos de ligação cruzada / Mass spectrometry and ion mobility in the characterization and of peptides from protein cross-linking experiments
There are several advantages associated with the use of mass spectrometry (MS) applied to structural studies of proteins, such as unlimited mass of target protein or protein complex, very low time and sample consumption, ease of manipulation and interpretation of the data obtained. In chemical cross-linking coupled to MS, bifunctional reagents (cross-linkers

5. Seleção e caracterização de peptídeos recombinantes ligantes a anticorpos monoclonais reativos a proteínas de Anaplasma marginale
Bovine anaplasmosis is caused by Anaplasma marginale and A. centrale. The most pathogenic and important species for cattle production is A. marginale, and is widely distributed in tropical, subtropical and temperate regions of the world. A. marginale is an intra-erythrocyte rickettsia of susceptible ruminants, biological and mechanically transmitted by ticks

6. Desenvolvimento de aplicações tecnológicas da metodologia de phage display no diagnóstico do câncer de próstata
Prostate cancer is the second cause of death in men by tumor, surpassed only by lung cancer. Its occurrence is estimated to be 51 to 100,000 cases per year. The increasing incidence levels observed may be partially explained by the evolution of diagnostic methods, quality of information systems and longer life expectancy. The identification of new cancer spe

7. Desenvolvimento de um método sorológico para o diagnóstico laboratorial da esquistossomose mansoni baseado em peptídeos sintéticos / Development of a serologic method for laboratory diagnosis of the schistosomiasis mansoni based on synthetic peptides
Based on algorithms of hidrophilicity and flexibility, obtained by the use of the ProtScale software, disposable at the site http://au.expasy.org/cgi-bin/protscale.pl, seven potentially antigenic peptides were selected from different Schistosoma mansoni proteins: cathepsin B (Sm31), heat shock protein (SmHSP-70), cathodic circulating antigen (CCA) and the po

9. Clinical uses of gut peptides.
OBJECTIVE: The authors review clinical applications of gut-derived peptides as diagnostic and therapeutic agents. SUMMARY BACKGROUND DATA: An increasing number of gut peptides have been evaluated for clinical use. Earlier uses as diagnostic agents have been complemented more recently by increasing application of gut peptides as therapeutic agents. METHOD: Th

10. Mapping of immunoreactive sites of pneumococcal pneumolysin by use of synthetic peptides.
In the search for better diagnostic tools and improved vaccines against pneumococcal diseases, continuous antigenic sites of the pneumococcal pneumolysin molecule were identified with partially overlapping synthetic peptides. Peptides were derived from the predicted amino acid sequence according to the known DNA sequence of pneumolysin. The immunoreactivitie

11. Use of a Synthetic Peptide Epitope of Asp f 1, a Major Allergen or Antigen of Aspergillus fumigatus, for Improved Immunodiagnosis of Allergic Bronchopulmonary Aspergillosis
Allergic bronchopulmonary aspergillosis (ABPA) is an immunologically complex allergic disorder caused by the fungal pathogen Aspergillus fumigatus. Elevated levels of total immunoglobulin E (IgE), specific IgE, and IgG antibodies in sera are important immunodiagnostic criteria for ABPA. International reference standards or standardized immunodiagnostic assay

12. Use of Synthetic Peptides Derived from the Antigens ESAT-6 and CFP-10 for Differential Diagnosis of Bovine Tuberculosis in Cattle
In Great Britain an independent scientific review for the government has concluded that the development of a cattle vaccine against Mycobacterium bovis infection holds the best long-term prospect for tuberculosis control in British herds. A precondition for vaccination is the development of a complementary diagnostic test to differentiate between vaccinated
