“BACKGROUND: Liquid emulsion membrane (LEM)-encapsulated live cells can be used to produce various products. This work reports on LEM-encapsulated cells for producing xylitol and models the production process.

RESULTS: Encapsulated cells of Candida mogii ATCC 18364 were used to produce xylitol from xylose. Soybean oil LEM consisting of 5% (w/v) lanolin and microwaxes was found most suitable for this process. The LEM-encapsulated cells were immobilized in a tubular biocatalytic loop. Xylitol was produced under oxygen-limited and aerobic conditions. Xylitol productivity Daporinad and yield were 0.005 g L-1 h(-1) and

0.52 g g(-1), respectively, for oxygen-limited operation. Under aerobic conditions, xylitol productivity increased greatly to 0.022 g L-1 h(-1), but yield on xylose declined to 0.49 g g(-1). Selleck A-1210477 A mathematical model successfully described substrate consumption

and product formation in the LEM-immobilized cell system.

CONCLUSION: Potentially, immobilized cell LEM systems are useful for certain fermentations and they can be successfully modeled, as shown by the example of xylitol from xylose process. (C) 2009 Society of Chemical Industry”
“The study assessed radiation exposure during EVAR. Two types of patient dose were estimated: effective dose (ED), which allows estimation of radiation risk to the EVAR patient population; and Peak Skin Dose (PSD), which allows us assess the potential for an individual

selleck products patient to receive a radiation skin injury. An ancillary aim was to examine dose optimization in EVAR procedures.

Based on 111 EVAR cases we estimated average ED as 12.4 mSv. Cumulative patient dose in our centre was lower than other studies because the follow up of EVAR patients is based on ultrasound rather than CT. PSD calculated using a published conversion formula closely matched measurements with calibrated gafchromic film. 99% of patients had an estimated PSD of < 2Gy. Results indicate that skin injuries are possible, but very unlikely in EVAR procedures at our centre.

EVAR is a high dose procedure and emphasis on dose optimisation is important. We broke the EVAR procedure into 15 steps and, in a phantom study, showed how skin dose changes as procedure steps are varied. The resulting dose matrix has the potential to be used as an educational tool to promote dose optimization. (C) 2012 European Society for Vascular Surgery. Published by Elsevier Ltd.

“Purpose of reviewTo provide information on the role of the essential trace element selenium, which enables appropriate thyroid hormone synthesis, secretion, and metabolism, and to discuss supplementation with various selenium compounds, which prevent thyroid diseases such as goiter and exert beneficial effects in thyroid autoimmune diseases.
