A 76-year-old man with a right lung adenocarcinoma and invasive Aspergillosis.

A 76-year-old male with adenocarcinoma on the right lung underwent five cycles of chemotherapy with pemetrexed disodium, cisplatin, and dexamethasone. Imaging studies of control showed a node in a cavitary lesion on the left lung, and the main hypothesis was Aspergillus infection. PCR was utilized and contributed to establish the early diagnosis in this patient with invasive aspergillosis.

In vitro antitumour activity of orsellinates.

Lichen phenolic compounds exhibit antioxidant, antimicrobial, antiproliferative, and cytotoxic activities. The purpose of this study was to evaluate the anticancer activity of lecanoric acid, a secondary metabolite of the lichen Parmotrema tinctorum, and its derivatives, orsellinates, obtained by structural modification. A cytotoxicity assay was carried out in vitro with sulforhodamine B (SRB) using HEp-2 larynx carcinoma, MCF7 breast carcinoma, 786-0 kidney carcinoma, and B16-F10 murine melanoma cell lines, in addition to a normal (Vero) cell line in order to calculate the selectivity index of the compounds.
