Comparison of conventional PCR, quantitative PCR, bacteriological culture and the Warthin Starry technique to detect Leptospira spp. in kidney and liver samples from naturally infected sheep from Brazil
(Elsevier B.V., 2012-09-01)
Leptospirosis is an infectious disease of worldwide importance. The development of diagnostic techniques allows sick animals to be identified, reservoirs to be eliminated and the disease prevented and controlled. The present ...
Total Reflection X-ray Fluorescence: a valuable analytic tool for environmental and biological studies
(Vibgyor, 2017-08)
This review collects the research of the recent years on biological or environmental studies in which Total Reflection X-Ray Fluorescence Spectrometry (TXRF) was used as a chemical analytical technique for quantification ...
Study on the use of oxidant scrubbers for elimination of interferences due to nitrogen dioxide in analysis of atmospheric dimethylsulfide
(Soc Brasileira Quimica, 2000-01-01)
In this work, oxidant scrubbers were evaluated for their ability to prevent sampling losses of dimethylsulfide caused by reactions with nitrogen dioxide. Various compounds and mixtures were used in the preparation of the ...
Techniques for the detection of pathogenic Cryptococcus species in wood decay substrata and the evaluation of viability in stored samples
(Instituto Oswaldo Cruz, Ministério da Saúde, 2019)
Evaluation of urine and vaginal self-sampling versus clinician-based sampling for cervical cancer screening: a field comparison of the acceptability of three sampling tests in a rural community of Cuenca, Ecuador
(2022)
Self-sampling methods for HPV testing have been demonstrated to be highly sensitive and specific. The implementation of these methods in settings with a lack of infrastructure or medical attention has been shown to increase ...
Nested sampling: an improved visual-census technique for studying reef fish assemblages
(2008)
Our aim was to devise visual sampling protocols to estimate densities in a morphologically and behaviorally diverse assemblage of reef fishes. The focus was on a design that is cost-effective and produces relatively accurate ...
Loss of samples in the tissue microarray technique: comparison between slides using adhesive tape and silanized slides
(Maney Publishing, 2011-06-01)
The tissue microarray (TMA) technique allows multiple tissue samples in a single block. Commercial adhesive tape is used to avoid the loss of tissue samples during the immunostaining process. Few reports exist in the ...

Spectroscopic and thermal characterization in poly(p-phenylene vinylene)/sol-gel silica sample
(Elsevier B.V., 2003-12-01)
The absorption and luminescence spectra for the poly(p-phenylene vinylene)/sol-gel silica with different thermal treatments were measured. A considerable increase in the luminescence was observed for the polymer introduced ...
