Recent studies suggest that alkalinizing treatments improve the course of chronic kidney disease (CKD), even in patients without overt metabolic acidosis. Here, we tested whether a decreased ability in excreting urinary acid rather than overt metabolic acidosis may be deleterious

Vero cells were grown adherent to microcarriers (Cytodex 1; 3 g L(-1)) using animal component free media in stirred-tank type bioreactors. Different strategies for media refreshment, daily media replacement (semi-batch), continuous media replacement (perfusion) and recirculation of media, were compared

BackgroundThe purpose of this study was to characterize hepatitis C virus (HCV)-associated differences in the expression of 47 inflammatory factors and to evaluate the potential role of peripheral immune activation in HCV-associated neuropsychiatric symptoms-depression, anxiety, fatigue, and pain.

A novel multifunctional envelope-type mesoporous silica nanoparticle (MEMSN) system combining the merits of pH-responsiveness, non-toxicity and biological specificity, is demonstrated for drug delivery and magnetic resonance imaging (MRI). This system is constructed by immobilizing acetals on the surface of mesoporous

The impairment of hepatic metabolism due to liver injury has high systemic relevance. However, it is difficult to calculate the impairment of metabolic capacity from a specific pattern of liver damage with conventional techniques. We established an integrated metabolic spatial-temporal
