Immunolocalization of CD80 and CD86 in Non-Small Cell Lung Carcinoma: CD80 as a Potent Prognostic Factor.

It has been demonstrated that tumor cells express programed cell death protein 1 (PD-L1) to escape T lymphocytes that express programed cell protein 1 (PD-1), and PD-1/PD-L1 immune checkpoint inhibitors have been regarded in lung cancer patients. CD80 and CD86 are members of B7 superfamily which regulates T lymphocyte activation and tolerance. However, immunolocalization of CD80 and CD86 has not been examined in the lung carcinoma tissues and their clinical significance remains unknown.

Detection of hydroquinone in a poisoning case.

A fatality due to the ingestion of photographic developer solution containing hydroquinone is described. Hydroquinone was extracted from autopsy materials and identified using gas chromatography-mass spectrometry (GC-MS). The concentration of hydroquinone in the urine, liver, and kidney were 3.
