Classification of lung cancer subtypes based on autofluorescence bronchoscopic pattern recognition: A preliminary study.

Background And Objectives: Lung cancer is the leading cause of cancer deaths worldwide. With current use of autofluorescent bronchoscopic imaging to detect early lung cancer and limitations of pathologic examinations, a computer-aided diagnosis (CAD) system based on autofluorescent bronchoscopy was proposed to distinguish different pathological cancer types to achieve objective and consistent diagnoses.

Methods: The collected database consisted of 12 adenocarcinomas and 11 squamous cell carcinomas.

Phytochemicals and Estrogen-Receptor Agonists from the Aerial Parts of Liriope platyphylla.

One new benzofuran, (2R)-(2',4'-dihydroxybenzyl)-6,7-methylenedioxy-2,3-dihydrobenzofuran (1), one new phenylisocoumarin, 3-(2'-hydroxyphenyl)-6,8-dihydroxy-7-methoxy-isocoumarin (2), and one new benzofuroisocoumarin, platyphyllarin C (3), were isolated from the ethanolic extract of Liriope platyphylla aerial parts, along with seventeen known compounds. The structures of the isolates were established by spectroscopic analysis and comparison with the literature data. The results indicated that structures 1-3 are uncommon in Nature.

Anti-viral effect of a compound isolated from Liriope platyphylla against hepatitis B virus in vitro.

The compound LPRP-Et-97543 was isolated from Liriope platyphylla roots and was observed to have potential anti-viral effects in HepG2.2.15 cells against hepatitis B virus (HBV).

Active Constituents from Liriope platyphylla Root against Cancer Growth In Vitro.

Liriope spicata is a well-known herb in traditional Chinese medicine, and its root has been clinically demonstrated to be effective in the treatment of metabolic and neural disorders. The constituents isolated from Liriope have also recently been shown to possess anticancer activity, although the mechanism of which remains largely unknown. Here, we illustrate the anticancer activity of LPRP-9, one of the active fractions we fractionated from the Liriope platyphylla root part (LPRP) extract.

The oestrogenic and anti-platelet activities of dihydrobenzofuroisocoumarins and homoisoflavonoids from Liriope platyphylla roots.

The ethanolic extract of Liriope platyphylla (Liliaceae) roots showed potential oestrogenic and anti-platelet activities. Twenty-six compounds were isolated and classified as 10 skeletons, including two unusual new dihydrobenzofuroisocoumarins, (+)-platyphyllarin A (1) and B (2), one new butanoate, ethyltributanoate (3), and two new homoisoflavanones, (-)-liriopein A (4) and B (5), along with 21 known compounds, including six homoisoflavonoids, one chalcone, six amides, one lignan, one fatty acid derivative, one alkaloid, three benzenoids, and two steroids. The biosynthetic pathway of compounds 1 and 2 was proposed in the current investigation.
