fragments antibody (scFv) against CART(55-102), and observed the effect of CART scFv on the expression of cocaine-induced behavior sensitization in mice. Results showed that the titer of CART scFv was 1.6 mu g/ml. Single administration of CART scFv (intraperitoneal 0.04, 0.2, and 1 mg/kg) reduced the increasing locomotor activity induced by chronic cocaine intake in mice (P < 0.05-0.01), but failed to affect the locomotor activity of naive mice. These results suggested that CART scFv may be a potential therapeutic tool to treat drug abuse. NeuroReport 22:433-436 (C) 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins.”
“Background: Failure to achieve

isonatric haemodialysis (HD) drives an expansion of extracellular volume leading to increased interdialytic weight KU55933 in vivo gain (IDWG). This may be a causative factor in the development ��-Nicotinamide datasheet of HD-induced cardiac injury. We examined total and diffusive sodium mass balance during HD. Methods: 24 chronic HD patients using a fixed 140 mmol/l sodium concentration were studied over 4 weeks. Dialysate and plasma conductivity and ionic mass balance (IMB) were recorded. IMB estimates total ionic transfer across the HD membrane. Results: Mean total IMB was 338 mmol indicating net sodium removal. Intrapatient variability was less than interpatient variability (coefficient of variation = 42 vs. 26%, respectively). The diffusive component of ionic mass balance (IMB(diff)) was 97 +/- 18 mmol approximating 29% (+/- 22-36) of total sodium removal. IMB(diff) also correlated with both plasma conductivity and predialysis plasma sodium (r(2) = 0.82 and 0.6, respectively; p < 0.0001) as well as the reduction in plasma conductivity and plasma sodium during HD (r(2) = 0.7 and 0.5, respectively; p < 0.0001). Conclusion: HD against a fixed dialysate sodium concentration of 140 mmol/l results in a wide range of sodium removal with a mean of 29% removed by diffusion. Online conductivity monitoring can be

utilized as part of a variety of strategies Vorinostat molecular weight to enable the delivery of individualised and isonatric HD. Further study is required to explore the utility of such strategies which may be crucial in reducing IDWG and HD-induced cardiac injury. Copyright (C) 2011 S. Karger AG, Basel”
“Event-related potentials were used to investigate the neural correlates of two-digit exact and approximate addition calculations. The results showed that the dissociation between exact and approximate calculations began at approximately 150ms after stimulus. In the left hemisphere, N170 amplitude elicited by exact calculation was larger than that elicited by approximate calculation; however, in the right hemisphere, N170 amplitudes elicited by the two calculation strategies were not significantly different. Moreover, a larger P3 amplitude was elicited by exact calculation than by approximate calculation.
