Chlorogenic acid prevents acetaminophen-induced liver injury: the involvement of CYP450 metabolic enzymes and some antioxidant signals     

Chun Pang  Yu-chen Sheng  Ping Jiang  Hai Wei  Li-li Ji 《Journal of Zhejiang University. Science. B》2015,16(7):602-610

Chlorogenic acid (CGA), a polyphenolic compound, is abundant in fruits, dietary vegetables, and some medicinal herbs. This study investigated the prevention of CGA against acetaminophen (AP)-induced hepatotoxicity and its engaged mechanisms. CGA reversed the decreased cell viability induced by AP in L-02 cells in vitro. In addition, CGA reduced the AP-induced increased serum levels of alanine/aspartate aminotransferase (ALT/AST) in vivo. The effect of CGA on cytochrome P450 (CYP) enzymatic (CYP2E1, CYP1A2, and CYP3A4) activities showed that CGA caused very little inhibition on CYP2E1 and CYP1A2 enzymatic activities, but not CYP3A4. The measurement of liver malondialdehyde (MDA), reactive oxygen species (ROS), and glutathione (GSH) levels showed that CGA prevented AP-induced liver oxidative stress injury. Further, CGA increased the AP-induced decreased mRNA expression of peroxiredoxin (Prx) 1, 2, 3, 5, 6, epoxide hydrolase (Ephx) 2, and polymerase (RNA) II (DNA directed) polypeptide K (Polr2k), and nuclear factor erythroid-2-related factor 2 (Nrf2). In summary, CGA ameliorates the AP-induced liver injury probably by slightly inhibiting CYP2E1 and CYP1A2 enzymatic properties. In addition, cellular important antioxidant signals such as Prx1, 2, 3, 5, 6, Ephx2, Polr2k, and Nrf2 also contributed to the protection of CGA against AP-induced oxidative stress injury.  相似文献

“Why Give Up Something That Works So Well?”: Retirement Expectations Among Academic Physicians     

Michelle Pannor Silver  N. Celeste Pang  Sarah A. Williams 《Educational gerontology》2015,41(5):333-347

For individuals with strong work identities, the decision to retire can be particularly challenging. For academic physicians, retirement is an important personal decision that also has far-reaching implications for the healthcare system. This is because academic physicians are responsible for producing the research from which key medical decisions are made, for training future healthcare providers, and for providing specialized care for patients. For this study, we conducted focus groups with academic physicians from a large research university in Canada and then performed inductive thematic analyses to examine perceptions and concerns about later life career transitions. This study highlights tensions between professional experiences for the next generation of physicians and individual struggles with personal identity. Findings suggest improvements to institutional programs that support flexible, agentive, and respectful retirement transitions will not only be beneficial but necessary as medical and university systems continue to grapple with issues of balanced recruitment and succession.  相似文献
