Heat-induced epitope retrieval (HIER) is widely used for immunohistochemistry on formalin fixed paraffin-embedded tissue and includes temperatures well above the melting point of paraffin. We therefore tested whether traditional xylene-based removal of paraffin is required on sections from paraffin-embedded tissue, when HIER is performed by vigorous boiling in 10 mM Tris/0.5 mM EGTA-buffer (pH=...

A new, simple, sensitive and selective method for the simultaneous determination of trace iron and aluminum by catalytic spectrophotometry was presented, based on the catalytic effects of iron and aluminum on the discoloring reaction of xylene cyanol FF proceeded by hydrogen peroxide and potassium periodate in weak nitric acid medium. No catalytic effect was obtained in the presence of hydrogen...

The objective of this paper was to study the anti-inflammatory and analgesic effects of Radix Angelicae Pubescentis (R.A.P) ethanol extracts. Three classic anti-inflammatory models and two analgesic models were used in this research. In anti-inflammatory tests, all the extracts have a certain inhibition on the acute inflammation induced by xylene, however, 60% ethanol extract significantly inhi...

High-efficiency production of xylene/trimethylbenzene from benzene/toluene with methanol is a potential way to promote the implementation on coupled cycle development strategy petrochemical and coal chemical industry optimize resource structure. At same time, relying innovation catalytic new materials, physical chemistry, intelligent capture technology, process engineering, other principles met...

Olfactory detection thresholds for 11 structurally diverse musk odorants and one non-musk odorant were obtained from 32 subjects. Hierarchical cluster analysis produced four groups of subjects. One group (n = 12) was uniformly sensitive to all musks; another (n = 16) was uniformly insensitive. Two groups of subjects contained otherwise insensitive individuals who were exceptionally sensitive to...

In a chemical plant, 40%–60% of energy and capital cost is tied to separation processes. As such, these processes must be selected carefully. Separation process can classified as thermal or non-thermal. Recent literature suggests that such distillation are inherently intensive relative their non-thermal counterparts membrane separation. The reasons for this claim traced back the success reverse...
