INTRODUCTION The role of natural bioactive substances in treating infections has been rediscovered as bacterial resistance become common to most of the antibiotics. Curcumin is a bioactive substance from turmeric. Owing to antimicrobial properties, its prospect as an antibacterial agent is currently under focus. MATERIALS AND METHODS We have evaluated the in vitro synergy of curcumin with ant...

In Yersinia pestis, Y. pseudotuberculosis, and Y. enterocolitica, phenotypic expression of virulence plasmid (pYV: 70-kb)-associated genetic determinants may include low-calcium response (Lcr, pinpoint colony, size = 0.36 mm), colony morphology (size = 1.13 mm), crystal violet (CV) binding (dark-violet colony), Congo Red (CR) uptake (red pinpoint colony, size = 0.36 mm), autoagglutination (AA =...

In this work, we present the stabilization of polar step edges along the [010] direction of calcite (10.4) by the presence of a water-soluble organic molecule, namely Congo Red. While characteristic etch pits are observed on the surface in the absence of the additive, no etch pits can be found in the presence of the additive. Using atomic force microscopy, we can directly follow the restructuri...

OBJECTIVE To describe a new, quantitative, and reproducible method for detecting deposits of amyloid A protein in aspirated fat tissue and to compare it with smears stained with Congo red. METHODS After extraction of at least 30 mg of abdominal fat tissue in guanidine, the amyloid A protein concentration was measured by a monoclonal antibody-based sandwich ELISA. RESULTS The concentrations ...

This study reports decolorization of Rhodamine B and Congo red by a partially purified laccase from Lentinus polychrous Lév. in the presence or absence of 2,2-azinobis (3-ethylbenzothiazoline-6sulfonate) diammonium salt (ABTS) as a redox mediator. The decolorization study showed that about 90% of Rhodamine B could be decolorized within 52 h, whereas Congo red could be decolorized more than 75% ...

A large number of microorganisms are capable of degrading cellulose, only a few of these microorganisms produce significant quantities of enzymes capable of completely hydrolyzing cellulose. Fungi are the main cellulase producing microorganisms. In this purposed study, four fungal species belonging to two genera i.e. Trichoderma and Aspergillus were isolated from different sources, screened and...

A punch biopsy of the axillary region was performed for histopathological study, staining with hematoxylin-eosin (Figure 2), periodic acid-Schiff (PAS), and Congo red. The histological findings included papillomatosis, orthokeratotic hyperkeratosis and epidermal acanthosis, focal atrophy of the granular layer, and mild hyperpigmentation of the basal layer of the epidermis. There was a moderate ...

We present a new laser system and nonlinear microscope, designed for differential nonlinear microscopy. The microscope features time-correlated single photon counting of multiphoton fluorescence generated by an alternating pulse-train of orthogonally polarized pulses. The generated nonlinear signal is separated using home-built electronics. Results are presented on fluorescence-detected nonline...

This research focused on the preparation and characterization of Cu@N-TiO2/Ti (N-TiO2/Ti decorated with Cu) thin film electrode and its activities test in photoelectrocatalytic system. This study investigated the time effect of Copper (Cu) electrodeposition and the concentration of nitrogen (N) in the photocatalytic characteristics of TiO2. The catalyst has been prepared for activities test on ...

beta2-Microglobulin accumulation with resultant tumor formation is a known albeit rare complication of long-term hemodialysis. Although these tumors may occur in various locations, subcutaneous shoulder nodules are very infrequent. We report a patient with end-stage kidney failure who had been on hemodialysis for 16 years and noted left shoulder nodules after initiation of hemodialysis; these n...
