    Description: We report the genetic encoding of a noncanonical, spin-labeled amino acid in Escherichia coli. This enables the intracellular biosynthesis of spin-labeled proteins and obviates the need for any chemical labeling step usually required for protein electron paramagnetic resonance (EPR) studies. The amino acid can be introduced at multiple, user-defined sites of a protein and is stable in E. coli even for prolonged expression times. It can report intramolecular distance distributions in proteins by double-electron electron resonance measurements. Moreover, the signal of spin-labeled protein can be selectively detected in cells. This provides elegant new perspectives for in-cell EPR studies of endogenous proteins.

    Description: To link to full-text access for this article, visit this link: http://dx.doi.org/10.1016/j.applthermaleng.2011.10.035 Byline: Steffen Stunkel (a), Daniel Illmer (a), Andreas Drescher (a), Reinhard Schomacker (b), Gunter Wozny (a) Abstract: The catalytic oxidative coupling of methane to higher hydrocarbons (OCM) as an alternative route to ethylene or liquid fuels obtained much attention. Besides the intensive research and novel developments in the catalyst field are a number of investigations conducted with reaction and separation engineering aspects at the TU Berlin. The aim of this research is the demonstration of the technical feasibility of the OCM process, including product recovery in a miniplant scale. In this article the gas treatment of the reaction product gas is discussed as a key part of the production chain from raw material to the product. In the OCM process the CO.sub.2 is treated as an unwanted by-product or waste. Nevertheless, the energy and the costs requirements for the whole OCM process are crucial for industrial applicability and must be kept as low as possible to operate economically. Therefore different separation methods are examined and several process alternatives are investigated. In this article the energy saving of a hybrid separation process based on a membrane-absorption process for the CO.sub.2 capture of the OCM process is presented and proved experimentally in miniplant scale. In a case study of the oxidative coupling of methane (OCM) process the development of an integrated gas treatment process for CO.sub.2 capture in the miniplant scale is presented and experimental results are discussed.

    Description: The efficacy of Heller myotomy in patients 〉40 years-a significant predictor suggesting a favorable response to pneumatic dilation-has been questioned. The aim of our study was to evaluate the results obtained in patients aged 40 years undergoing minimally invasive surgery (MIS) for achalasia. In January 2008, we established the MIS technique for achalasia in our clinic. In the following period from January 2008 to March 2011, 74 patients underwent primary laparoscopic myotomy for achalasia. The procedure was accomplished with an anterior 180° semifundoplication according to Dor in all patients. The Eckardt score and the Gastrointestinal Quality of Life Index (GQLI) served as outcome measures. The median age of patients was 45.5 years (range, 18-85 years) with a median duration of preoperative achalasia symptoms of 57 months (range, 2-468 months). There were no conversions to open surgery and-except for one patient with a sterile pleural effusion-no postoperative complications. At a median follow-up of 12 months, the preoperative Eckardt score of 7.0 (range, 3-12) was found to be significantly decreased to a median of 2 (range, 0-6; P 40 years, the postoperative Eckardt score obtained in the older patient population was not significantly lower (P = 0.074). There was no statistically significant difference between the two groups with respect to the postoperative GQLI (P = 0.860). Neither gender nor preoperative Botox injection or pneumatic dilation inserted a significant influence on the postoperative clinical outcome (P 〉 0.05). Laparoscopic Heller myotomy for achalasia is associated with a high success rate as the primary therapeutic option and after failure of endoscopic therapy. It can be performed safely and with favorable outcomes also in patients 〉40 years. However, the long-term durability of the procedure remains to be established.

    Description: Saturated branched fatty derivatives are of great interest for the lubricants and cosmetics industry due to their improved temperature and viscosity behavior compared to the corresponding linear homologues. One way to produce saturated branched derivatives is the homogeneous rhodium‐catalyzed conjugation and co‐oligomerization of linoleic compounds based on renewable resources, e.g., sunflower oil, with ethene. The catalyst extraction behavior of the homogeneous rhodium catalyst RhCl·3HO from saturated branched fatty derivatives for catalyst recycling was studied. Investigation of the extraction parameters was performed using the model substance isostearic acid. Additionally, extraction of rhodium from co‐oligomer mixtures with different grade of saturation was carried out successfully. Also, the influence of solvent residues from prior reaction steps was evaluated. Branched fatty derivatives possess huge potential for the cosmetics or lubricants industry. An example for a commercially available product is isostearic acid. Co‐oligomers of linoleic compounds and ethene represent higher branched products produced by homogeneous rhodium catalysis. Rhodium extraction from such branched derivatives is proposed as a possible catalyst recycling method.
