Inhibitory effects of food additives derived from polyphenols on staphylococcal enterotoxin A production and biofilm formation by Staphylococcus aureus.

In this study, we examined the inhibitory effects of 14 food additives derived from polyphenol samples on staphylococcal enterotoxin A (SEA) production and biofilm formation by Staphylococcus aureus. Tannic acid AL (TA), Purephenon 50 W (PP) and Polyphenon 70A (POP) at 0.25 mg/mL and Gravinol®-N (GN), Blackcurrant polyphenol AC10 (BP), and Resveratrol-P5 (RT) at 1.

Introduction and utility of liquid-based cytology on aspiration biopsy of peripheral nodular lesions of the lung.

In the present study, aspiration biopsy cytology (ABC) was used for the diagnosis of peripheral nodular lesions in the lung (PNLL), and liquid-based cytology (LBC) was carried out on the material collected to evaluate it in comparison with the conventional method (CM). The subjects comprised 130 cases that underwent computed tomography (CT)-guided ABC for PNLL. A total of 73 cases received a tumor resection, with a diagnosis based on the pathology, while 57 cases were followed up, as the tumor showed no change on the radiological examinations.

Possibility of molecular targeting therapy for the treatment of cancer of unknown primary origin by analysis of intracellular signaling molecules.

Recently, antibody-mediated epidermal growth factor receptor (EGFR) blockade has become a major research focus, and a number of clinical studies on this new treatment have been started in the field of clinical oncology. This retrospective study investigated the role of KRAS gene mutations and clinical features for possibilities for new therapies in patients with cancer of unknown primary (CUP). We investigated the role of KRAS, PIK3CA and BRAF gene mutations and clinical features for possibilities for new therapies in patients with CUP.
