Gossypin induces G2/M arrest in human malignant glioma U251 cells by the activation of Chk1/Cdc25C pathway.

Gossypin is a flavone that was originally isolated from Hibiscus vitifolius and has traditionally been used for the treatment of diabetes, jaundice, and inflammation. Recently, gossypin was found to have potent anticancer properties; however, its effect on human gliomas still remain unknown. To investigate the potential anticancer effects of gossypin on malignant gliomas and analyze the associated molecular mechanisms, we treated human glioma U251 cells with gossypin.

In vitro antimicrobial effect of cefazolin and cefotaxime combined with minocycline against Vibrio cholerae non-O1 non-O139.

The most common clinical manifestation of Vibrio cholerae non-O1 non-O139 is gastroenteritis. This vibrion may also cause bacteremia, soft tissue infection, and other extraintestinal invasive disease, especially in immunocompromised patients. This study evaluated the current status of antimicrobial resistance in clinical isolates of V.

Bactericidal effects of toluidine blue-mediated photodynamic action on Vibrio vulnificus.

Vibrio vulnificus is a gram-negative, highly invasive bacterium responsible for human opportunistic infections. We studied the antibacterial effects of toluidine blue O (TBO)-mediated photodynamic therapy (PDT) for V. vulnificus wound infections in mice.

In vitro and in vivo activities of fluoroquinolones against Aeromonas hydrophila.

Aeromonas hydrophila, an uncommon human pathogen, can cause invasive infections in immunocompromised individuals. As the fluoroquinolones have been shown to be active in vitro against mesophilic aeromonads and clinical experience with the use of fluoroquinolones to treat aeromonads infections is limited, the antimicrobial activities of five selected drugs (ciprofloxacin, gatifloxacin, levofloxacin, lomefloxacin, and moxifloxacin) against A. hydrophila were studied in vitro and in mice.
