“Objective: The goal of the present study was to extend our previous findings on long-term methamphetamine (MA) use and drug abstinence on brain metabolite levels in an expanded group of MA-dependent individuals.

Methods: Seventeen MA abusers with sustained drug abstinence (1-5 years), 30 MA abusers with short-term drug abstinence (1-6 months) and 24 non-substance using

controls were studied using MR spectroscopy (MRS). MRS measures of NAA/Cr, Cho/Cr and Cho/NAA were obtained in the anterior cingulate cortex (ACC) and in the primary visual cortex (PVC).

Results: ACC-Cho/NAA values were abnormally high in the short-term abstinent group compared to controls [F(1,52)=18.76, p < 0.0001]. No differences were observed

between controls and the long-term abstinent group [F(1,39) = 0.97, p = 0.97]. New evidence of lower ACC-NAA/Cr levels were observed in the short-term abstinent MA abusers compared to controls [F(1,52)= 23.05, p < 0.0001] and long-term abstinent MA abusers [F(1,45) = 7.06, p = 0.01]. No differences were observed between long-term abstinent MA abusers and controls [F(1,39) = 0.48, p = 0.49].

Conclusions: The new findings of relative H 89 in vitro NAA/Cr normalization across periods of abstinence suggest that adaptive changes following cessation of MA abuse may be broader than initially thought. These changes may contribute to some

degree of normalization of neuronal function in the ACC. (C) 2010 Elsevier Ireland Ltd. All rights reserved.”
“Lipase-catalyzed methanolysis of vegetable oils has attracted considerable interests for the production of biodiesel (BD). However, the activity of lipase such as Novozym 435 (immobilized Candida antarctica AC220 Angiogenesis inhibitor lipase B) is negatively affected by methanol. To minimize this problem, two-step lipase catalysis was investigated. Crude palm oil (CPO), which is relatively cheaper because of avoiding refining cost, was used as the source of BD. CPO was first hydrolysed to fatty acids (FA), which was then esterified to BD. Candida rugosa and Novozym 435 lipases were used as biocatalysts for the hydrolysis of CPO and the esterification of FA, respectively. The complete conversion of CPO to FA was achieved under an optimal condition of buffer to CPO ratio 1:1 (v/v), buffer pH 7.0, lipase 0.1 wt.% of CPO, isooctane to CPO ratio 1:1 (v/v), temperature 30 degrees C, shaking speed 250 rpm and time 4 h. The methyl esterification of FA with 1.2-fold stoichiometric excess of methanol reached the equilibrium after 2 h at which BD yield was 98%. C. rugosa and Novozym 435 lipases were repeatedly used for 10 and 50 cycles, respectively without significant loss of their activities.
