Article Synopsis
- Primary liver cancers, like HCC, ICC, and cHCC-CCA, are major causes of cancer-related deaths, and distinguishing between these types can be challenging due to their similar features.
- This study analyzed 140 patients who had liver tumor resections, reclassifying tumors and comparing the clinicopathological characteristics and survival rates of HCC, ICC, and cHCC-CCA.
- The results showed that most patients had HCC, with worse overall survival and disease-free survival for ICC and cHCC-CCA, highlighting the need for careful evaluation to identify cholangiolar components, which signal a poorer prognosis.

This study optimizes two factors, pH and initial [H2O2], in the ultraviolet (UV)/H2O2/microwave (MW) process through experimental design and assesses the effect of MWs on the colour removal of an azo-dye (tartrazine) solution that was favoured by an acidic pH. The estimated optimal conditions were: initial [H2O2] = 2.0 mmol L(-1) and pH = 2.

Thyroid Laboratory, Hospital das Climcas, University of SĀao Paulo Medical School, SĀao Paulo, Brazil.
Samples from 2 different locations within the same euthyroid multinodular goiters (SMG) and normal (N) human thyroids were assayed for their content of DNA, thyroglobulin (Tg), and stable iodine (1), and determined the response of adenosine 3',5'-cyclic monophosphate (cAMP) to TSH and NaF. Quantitative morphological estimation of histological components in the thyroid was performed and correlated with functional parameters. Regardless the zonal evaluation, in SMG the mean (± SD) DNA content (⧎g/mg tissue) (1.
