Multisite survey of bacterial contamination in ready-to-eat meat products throughout the cooking and selling processes in urban supermarket, Nanjing, China.

Objective: Ready-to-eat (RTE) meat is a kind of popular instant food easily contaminated by microbes, which is one of the causes of foodborne diseases. This study analyzes the possible sources of RTE food bacterial contamination during processing and subsequent selling.

Method: Samples of eight kinds of RTE meat were collected from four supermarkets in Nanjing, China.

Attenuation of Pseudomonas aeruginosa biofilm by hordenine: a combinatorial study with aminoglycoside antibiotics.

Pseudomonas aeruginosa is a ubiquitous pathogen that is the leading cause of chronic infections. Bacterial biofilm formation facilitates CF development and restricts the anti-bacterial potential of many current antibiotics. The capacity of P.

Stimulation of the proliferation of human normal esophageal epithelial cells by fumonisin B and its mechanism.

Previous epidemiological studies have demonstrated a correlation between fumonisin B (FB) and human esophageal cancer in China, Iran and South Africa. The purpose of this study was to investigate the effects of FB on the proliferation, cell-cycle and apoptosis of normal human esophageal epithelial cells (HEECs) and to explore the molecular mechanisms of these effects. The proliferation of HEECs treated with FB was assessed using a colorimetric assay, while analyses of the cell cycle and apoptosis were performed using flow cytometry and the measurement of the protein expressions of genes associated with the cell cycle was conducted using western blotting.

Effect of fumonisin B₁ on the cell cycle of normal human liver cells.

Fumonisin B1 (FB1) is a well-known liver and kidney carcinogen in rodents and humans. The aim of the present study was to investigate the effect of FB1 on the proliferation and cell cycle of the normal human liver cell line HL-7702 and to explore the underlying molecular mechanisms of action. The cells were treated with FB1 (0.
