Oxidation State of Manganese in Rock Varnish
Rock varnish is generally understood to be a 5-500 micrometer thick nanostratigraphic coating consisting of approximately 70% clay glued together by 30% iron and manganese oxides, which forms on the surfaces of rocks in most semi-arid to hyper-arid climates. Many investigators believe that manganese exists in rock varnish mainly as birnessite, and that varnish has at least a partial biological ...
متن کاملFrequency of false positive responses in patients with multiple positive reactions in patch test

Patch test is the standard test to recognize responsible allergen. The objective of this study was to evaluate the frequency of false positive patch test responses in patients with Exited Skin Syndrome (ESS).Materials...

متن کاملLong Lasting Allergic Patch Test Reactions: A Literature Review.
Long-lasting allergic patch test reactions (LLAPTR) are those in which the clinical features of palpable erythema are still present at the site of a positive allergic patch test reaction 14 or more days after application of the allergen. LLAPTR have been described for a wide range of contact allergens, many of these included in the baseline patch test series. LLAPTR are far from uncommon; they ...
متن کاملVariability in patch test reactions--first report from the Norwegian Patch Test Registry.
BACKGROUND A nation-wide Norwegian Patch Test Registry (NOLAR) was established in 2005 as a collaboration between six dermatology departments. International, multi-centre studies have documented great variability in the frequency of positive patch test reactions, considered as mainly due to heterogeneity of test populations. OBJECTIVES To analyse the variability of positive test reactions by ...
