Permanent and Selective Capital Account Management Regimes as an Alternative to Self-Insurance Strategies in Emerging-Market Economies

Currency market intervention-cum-reserve accumulation has emerged as the favored selfinsurance strategy in recipient countries of excessive private capital inflows. This paper argues that capital account management represents a less costly alternative line of defense deserving renewed consideration, especially in the absence of fundamental reform of the global monetary and financial order. Mainstream arguments in favor of financial globalization are found unconvincing; any indirect benefits allegedly obtainable through hot money inflows are equally obtainable without actually tolerating such inflows. The paper investigates the experiences of Brazil, Russia, India, and China (the BRICs) in the global crisis and subsequent recovery, focusing on their respective policies regarding capital flows

The recombinant beta subunit of C-phycocyanin inhibits cell proliferation and induces apoptosis

C-Phycocyanin (C-PC) from blue-green algae has been reported to have various pharmacological characteristics, including antiinflammatory and anti-tumor activities. In this study, we expressed the beta-subunit of C-PC (ref to as C-POP) in Escherichia coli. We found that the recombinant C-PC/beta has anti-cancer properties. Under the treatment of 5 mu M of the recombinant C-PC/beta, four different cancer cell lines accrued high proliferation inhibition and apoptotic induction. Substantially, a lower response occurred in non-cancer cells. We investigated the mechanism by which C-PC/beta inhibits cancer cell proliferation and induces apoptosis. We found that the C-PC/beta interacts with membrane-associated beta-tubulin and glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Under the treatment of the C-PC/beta, depolymerization of microtubules and actin-filaments were observed. The cells underwent apoptosis with an increase in caspase-3, and caspase-8 activities. The cell cycle was arrested at the G0/G1 phase under the treatment of C-PC/beta. In addition, the nuclear level of GAPDH decreased significantly. Decrease in the nuclear level of GAPDH prevents the cell cycle from entering into the S phase. Inhibition of cancer cell proliferation and induction of apoptosis may potentate the C-POP as a promising cancer prevention or therapy agent. (c) 2006 Elsevier Ireland Ltd.

First report of the cyanotoxins cylindrospermopsin and deoxycylindrospermopsin from Raphidiopsis curvata (Cyantobacteria)

A strain of Raphidiopsis (Cyanobacteria) isolated from a fish pond in Wuhan, P. R. China was examined for its taxonomy and production of the alkaloidal hepatotoxins cylindrospermopsin (CYN) and deoxy-cylindrospermopsin (deoxy-CYN). Strain HB1 was identified as R. curvata Fritsch et Rich based on morphological examination of the laboratory culture. HB1 produced mainly deoxy-CYN at a concentration of 1.3 mg(.)g(-1) (dry ut cells) by HPLC and HPLC-MS/MS. CYN was also detected in trace amounts (0.56 mug(.)g(-1)). A mouse bioassay did not show lethal toxicity when tested at doses up to 1500 mg dry weight cells(.)kg(-1) body weight within 96 h, demonstrating that production of primarily deoxy CYN does not lead to significant mouse toxicity by strain BB I. The presence of deoxy-CYN and CYN in R curvata suggests that Raphidiopsis belongs to the Nostocaceae, but this requires confirmation by molecular systematic studies. Production of these cyanotoxins by Raphidiopsis adds another genus, in addition to Cylindrospemopsis, Aphanizomenon, and Umezakia, now known to produce this group of hepatotoxic cyanotoxins. This is also the first report from China of a CYN and deoxy-CYN producing cyanobacterium

How to Sustain the Chinese Economic Miracle? The Risk of Unraveling the Global Rebalancing

This paper investigates China's role in creating global imbalances, and the related call for a massive renminbi revaluation as a (supposed) panacea to forestall their reemergence as the world economy recovers from severe crisis. We reject the prominence widely attributed to China as a cause of global imbalances and the exclusive focus on the renminbi-dollar exchange rate as misguided. And we emphasize that China's response to the global crisis has been exemplary. Apart from acting as a growth leader in the global recovery by boosting domestic demand to offset the slump in exports, China has in the process successfully completed the first stage in rebalancing its economy, which is in stark contrast to other leading trading nations that have simply resumed previous policy patterns. The second stage in China's rebalancing will consist of further strengthening private consumption. We argue that this will be best supported by continued reliance on renminbi stability and capital account management, so as to assure that macroeconomic policies can be framed in line with domestic development requirements
