Low amounts of human pharmaceuticals in the aquatic environment can affect bacteria, animals and ultimately humans. Here, the environmental consequences of a shift in prescription behavior from prednisolone to berberine was modeled using an environmental decision support system based on four consecutive steps: emission, fate, exposure and effect. This model estimates the relative aquatic and human health impacts of alternative pharmaceutical prescriptions throughout Europe. Since a Defined Daily Dose (DDD) of berberine has yet to be formulated, the environmental impacts of berberine and prednisolone were compared under the assumption of equal DDDs...

Age-related macular degeneration (AMD) is the leading cause of central vision loss in the elderly with less effective treatment, especially for dry AMD (90% of AMD). Although the etiology of this disease is not well elucidated, increasing evidences indicate that excessive reactive oxygen species (ROS) impairing the physiological functions of retinal pigment epithelium (RPE) cells may be one of the main causes. Therefore, it could be a great strategy to find some drugs that can effectively protect RPE cells from oxidative damage which is desired to treat and slow the process of AMD...

The gonococcal NorM efflux pump exports substrates with a cationic moiety including quaternary ammonium compounds such as berberine (BE) and ethidium bromide (EB) as well as antibiotics such as ciprofloxacin and solithromycin. The norM gene is part of a four gene operon that is transcribed from a promoter containing a polynucleotide tract of 6 or 7 thymidines (Ts) between the -10 and -35 hexamers; the majority of gonococcal strains analyzed herein contained a T-6 sequence. Primer extension analysis showed that regardless of the length of the poly-T tract, the same transcriptional start site (TSS) was used for expression of norM Interestingly, the T-6 tract correlated with a higher level of both norM expression and gonococcal resistance to NorM substrates BE and EB...
