Feathers are useful to determine mercury (Hg) contamination. We evaluated the mercury concentration in feathers of Magellanic penguins (Spheniscus magellanicus) age 1.5years to 25years at Punta Tombo, Argentina before and during their molt. Mercury ranged between <1.4 and 367ng/gdryweight, with three extreme high values (8996ng/g, 3011ng/g and 1340ng/g) all in young adults. The median concentration...
Silymarin, an extract from milk thistle (Silybum marianum), and its purified flavonolignans have been recently shown to inhibit hepatitis C virus (HCV) infection, both in vitro and in vivo. In the current study, we further characterized silymarin's antiviral actions. Silymarin had antiviral effects against hepatitis C virus cell culture (HCVcc) infection that included inhibition of virus entry, RNA...
