1. Device for Streptavidin Detection Using LSPR and Electrochemical Transductions on the same Platform
Research in biosensing currently occupies an important role among biomolecular detection techniques, especially with respect to medical diagnoses. Is this sense, the development of biosensors based on the localized surface plasmon resonance (an optical transducer) or electrochemical transductions have been highlighted. However, optical and electrochemical de

2. New Strategy for Streptavidin Detection Using AuNRs/PAAm Hydrogel Composites
Localized surface plasmon resonance (LSPR) is a collective oscillation of free electrons induced by the incident light in nanometric surfaces of conductive materials. Gold nanorods (AuNRs) have been studied for plasmonic devices due to their anisotropic properties. Herein, we report the construction of a specific biosensor using polyacrylamide (PAAm) as the

4. Immunohistochemical expression of biglycan and decorin in the pulp tissue of human primary teeth during resorption
Primary teeth are interesting models that can be used to study physiological and pathological processes involving cells and extracellular matrices in hard and soft tissues. This study investigated the expression and distribution of biglycan and decorin-the non-collagenous components of the extracellular matrix-in primary teeth tissue, during physiological ro

5. Marcadores tumorais bioquímicos e imunocitoquímicos em efusões neoplásicas caninas / Biochemical and immunocytochemical tumor markers in canine neoplastic effusions
The cavity effusions frequently occur in the clinical routine of dogs. In most cases the effusions are benign caused by circulatory system disorders. Neoplasms are common causes of effusions in dogs, however not always the tumor cells are found in cytopathologycal analysis. The dosage of tumor markers is an alternative to make the neoplastic effusion diagnos

6. Expressao da ciclooxigenase-2 (COX-2) e do fator de necrose tumoral (TNF-) na viabilidade de retalho cutaneo randomico em ratos apos a irradiacao laser de baixa intensidade / Expressao da ciclooxigenase-2 (COX-2) e do fator de necrose tumoral (TNF-) na viabilidade de retalho cutaneo randomico em ratos apos a irradiacao laser de baixa intensidade / Expression of cyclooxygenase-2 (COX-2) and tumor necrosis factor-alpha (TNF-á) on viability of random skin flaps in rats after low level laser therapy / Expression of cyclooxygenase-2 (COX-2) and tumor necrosis factor-alpha (TNF-á) on viability of random skin flaps in rats after low level laser therapy
Objective: To investigate the effect of low intensity laser irradiation on viability of random skin flap in rats and to evaluate the concentration levels of COX-2 and TNF- á. Method: The sample consisted of 24 rats Wistar EPM-1 randomly divided into three groups. All animals were subjected to a surgically induced cranial base dorsal skin flap, measuring 10X

7. Rapid identification of Mycobacterium tuberculosis complex by a novel hybridization signal amplification method based on self-assembly of DNA-streptavidin nanoparticles
Rapid detection of Mycobacterium tuberculosis complex (MTBC) is a critical step in controlling tuberculosis (TB). In this study, we used IS6110 as the specific identification target to develop a novel hybridization signal amplification method (HSAM) for the rapid and direct detection of MTBC from clinical sputum specimens. This system consists of magnetic be

8. Immunohistochemical staining of Langerhans cells in HPV-positive and HPV-negative cases of oral squamous cells carcinoma
The Human Papillomavirus (HPV) has been strongly implicated in development of some cases of oral squamous cell carcinoma (OSCC). However, the immunological system somehow reacts against the presence of this virus. Among the cells involved in such mechanism of defense Langerhans cells (LC) stand out, which are responsible for processing and presenting antigen

9. Radiolabeled nano-peptides show specificity for an animal model of human PC3 prostate cancer cells
OBJECTIVES: Cancer has been investigated using various pre-targeting techniques or models focusing on radiobombesin analogues; however, both are not offered together. In this study, nano-bombesin labeling by a pre-targeting system was undertaken to develop an alternative approach for prostate tumor treatment. METHODS: A two-step pre-targeting system utilizin

10. Characterization of 13 microsatellite loci developed from Meconopsis horridula
Meconopsis horridula is one of the eight most famous flowers in Chinese province of Yunnan. In this study, a modified biotin-streptavidin capture method was used to detect 13 microsatellite markers in the genome of M. horridula. The polymorphism of each locus was assessed in 24 samples collected from four populations. The number of alleles per locus ranged f

11. p53 and MDM2 protein expression in actinic cheilitis
Actinic cheilitis is a potentially malignant lip lesion caused by excessive and prolonged exposure to ultraviolet radiation, which can lead to histomorphological alterations indicative of abnormal cell differentiation. In this pathology, varying degrees of epithelial dysplasia may be found. There are few published studies regarding the p53 and MDM2 proteins

12. Obtaining of recombinant strains of the yeast Kluyveromyces lactis producers of streptavidin / Obtenção de linhagens de Kluyveromyces lactis recombinantes produtoras de estreptavidina
The high affinity interaction streptavidin-biotin provides an excellent system for industrial enzyme separation or immobilization involving a fused streptavidin-enzyme and a biotinylated support. In order to produce proteins with affinity to biotin, we have modified the commercial K. lactis system, pKLAC1 (New England Biolabs), a LAC4 promoter-driven integra
