Resveratrol plays important role in protective mechanisms in renal disease - mini-review

Resveratrol (RESV) is a polyphenolic compound found in various plants, including grapes, berries and peanuts, and its processed foods as red wine. RESV possesses a variety of bioactivities, including antioxidant, anti-inflammatory, cardioprotective, antidiabetic, anticancer, chemopreventive, neuroprotective, renal lipotoxicity preventative, and renal protective effects. Numerous studies have demonstrated that polyphenols promote cardiovascular health. Furthermore, RESV can ameliorate several types of renal injury in animal models, including diabetic nephropathy, hyperuricemic, drug-induced injury, aldosterone-induced injury, ischemia-reperfusion injury, sepsis-related injury, and endothelial dysfunction. In addition, RESV can prevent the increase in vasoconstrictors, such as angiotensin II (AII) and endothelin-1 (ET-1), as well as intracellular calcium, in mesangial cells. Together, these findings suggest a potential role for RESV as a supplemental therapy for the prevention of renal injury.

The real mechanisms of the global economy

The paper presents the main arguments of Bresser Pereira's Globalization and Competition. Development strategies based on the 'conventional orthodoxy' are shown to carry serious drawbacks ("Dutch disease", pernicious effects of external saving, currency overvaluation), while a 'new developmentalism' is promoted, in spite of the widespread belief that the nation-states have been dispossessed of their room for manoeuvre because of the globalization process. The "new developmentalism" is based on domestic finance, balanced public budgets, moderate interest rates and competitiveness policies aimed at neutralizing the tendency to exchange rate overappreciation. The paper also points out a few theoretical questions the book raises.
