Its overall lipid productivity was 113 mg/Lid when grown under non-optimal conditions using batch cultivation. A two-step response surface methodology was adopted to optimize its cultivation conditions. The overall lipid productivity was increased to 263 mg/L/d when the cells were grown under the optimized conditions of 6.6 mM initial nitrogen level and 6 days AZD9291 mouse nitrogen depletion treatment in 700 mu mol/m(2)/s

light intensity at 35 degrees C using batch cultivation. Fed-batch and semi-continuous cultivations were employed to further increase its lipid productivity to 213 and 302 mg/L/d, respectively. The 302 mg/L/d is the highest overall lipid productivity of microalgae ever reported in the literature. This study provides the information required for the design and operation of photobioreactors for large scale outdoor cultivation of this species. (C) 2014 Elsevier Ltd. All rights reserved.”
“BackgroundTreatment of acne scars with ablative fractional CO2 laser appears to be an effective and well-tolerated treatment. However, so far the influence of treatment interval has not been evaluated. ObjectiveTo evaluate whether treatment of acne scars with fractional CO2 laser resurfacing at 1-month interval achieves better results with no difference in the occurrence of adverse effects, than treatment given at 3-months interval. MethodsPatients

(n=13) with symmetrical atrophic acne scars on right and left sides of the mid-face and lower-face were randomized to two fractional CO2 laser treatments at 1-month versus 3-month intervals. Blinded on-site evaluations

were performed 1 and 6 months after the last treatment GNS-1480 on 10-point scales. Endpoints were scar atrophy, patient satisfaction, and adverse NVP-BSK805 chemical structure effects. ResultsPre-operatively, acne scars were moderately atrophic (5.861.87). After treatment acne scars appeared with less atrophy on both treated sides 1 month postoperatively (1-month interval 1.96 +/- 1.23, P smaller than 0.0001; 3-months interval 1.82 +/- 1.08, P=0.0006) and 6 months postoperatively (1-month interval 1.56 +/- 1.24, P=0.0021; 3-months interval 1.33 +/- 1.66, P=0.0002). The treatment interval did not influence the improvement of scar atrophy at any time postoperatively (P=0.81). Patients were moderately and equally satisfied with the treatment result on facial sides (P=0.93). Postoperative adverse effects were minor and not influenced by the treatment interval. ConclusionsFractional CO2 laser resurfacing improves atrophic acne scars and a treatment interval of either 1-month or 3-months does not seem to influence the improvement of scar atrophy nor the occurrence of postoperative adverse effects.
