Abstract
Volume changes of human T-lymphocytes (Jurkat line) exposed to hypotonic carbohydrate-substituted solutions of different composition and osmolality were studied by videomicroscopy. In 200 mOsm media the cells first swelled within 1-2 min and then underwent regulatory volume decrease (RVD) to their original isotonic volume within 10-15 min. RVD also occurred in strongly hypotonic 100 mOsm solutions of di- and trisaccharides (trehalose, sucrose, raffinose). In contrast to oligosaccharide media, 100 mOsm solutions of monomeric carbohydrates (glucose, galactose, inositol and sorbitol) inhibited RVD. The complex volumetric data were analyzed with a membrane transport model that allowed the estimation of the hydraulic conductivity and volume-dependent solute permeabilities. We found that under slightly hypotonic stress (200 mOsm) the cell membrane was impermeable to all carbohydrates studied here. Upon osmolality decrease to 100 mOsm, the membrane permeability to monomeric carbohydrates increased dramatically (apparently due to channel activation caused by extensive cell swelling), whereas oligosaccharide permeability remained very poor. The size-selectivity of the swelling-activated sugar permeation was confirmed by direct chromatographic measurements of intracellular sugars. The results of this study are of interest for biotechnology, where sugars and related compounds are increasingly being used as potential cryo- and lyoprotective agents for preservation of rare and valuable mammalian cells and tissues.

Abstract
Alloarthroplasty has largely replaced traditional procedures in arthrosis of hip and knee joints. In contrast the role of alloarthroplasty in comparison to traditional procedures in hand surgery has been uncertain. To evaluate this question every registered hand surgery department (n=307) in Germany received a questionnaire requesting information on number and type of implanted prostheses and traditional procedures concerning the wrist joint, distal radioulnar joint (DRUJ), first carpometacarpal joint (CMC), metacarpal phalangeal joint (MP), interphalangeal joint (PIP), and preferred characteristics of the prostheses. Of the 307 hand surgery departments, 150 (57% of the hospitals and 42% of the visiting surgeons) participated in the inquiry. Per year, only 98 wrist prostheses were implanted (distributed among five different models) but 1534 traditional procedures were performed. The Sauve-Kapandji procedure was the most popular for the DRUJ and was performed 264 times per year. In comparison 24 hemiarthroplasties were implanted at the DRUJ. Trapezectomy remains the standard procedure for arthrosis of the first CMC joint (n=1399). The future importance of alloarthroplasty of the CMC joint is doubted by the majority of participating hand surgeons (90.3%). In contrast the majority (85.3/71.8%) is convinced that alloarthroplasty will be of importance for the MCP and PIP joints, respectively. Currently, the number of implanted prostheses is close to the number of traditional procedures performed at the MP joint. Irrespective of the joint involved, cementless anchorage is preferred as is the surface replacement anatomical design. The results confirm that alloarthroplasty in hand surgery is of minor importance. Thus, the role of alloarthroplasty differs depending on the joint involved. Traditional procedures except for the MP joint continue to be of major importance in hand surgery.

Abstract
18F-labeled non-sulfonylurea hypoglycemic agent (S)-2-(2-[(18)F]fluoroethoxy)-4-((3-methyl-1-(2-piperidin-1-yl-phenyl)-butylcarbamoyl)-methyl)-benzoic acid ([(18)F]repaglinide), a derivative of the sulfonylurea-receptor (SUR) ligand repaglinide, was synthesized as a potential tracer for the non-invasive investigation of the sulfonylurea 1 receptor status of pancreatic beta-cells by positron emission tomography (PET) in the context of type 1 and type 2 diabetes. [(18)F]Repaglinide could be obtained in an overall radiochemical yield (RCY) of 20% after 135 min with a radiochemical purity higher than 98% applying the secondary labeling precursor 2-[(18)F]fluoroethyltosylate. Specific activity was in the range of 50-60 GBq/micromol. Labeling was conducted by exchanging the ethoxy-moiety into a 2-[(18)F]fluoroethoxy group. To characterize the properties of fluorinated repaglinide, the affinity of the analogous non-radioactive (19)F-compound for binding to the human SUR1 isoform was assessed. [(19)F]Repaglinide induced a complete monophasic inhibition curve with a Hill coefficient close to 1 (1.03) yielding a dissociation constant (K(D)) of 134 nM. Biological activity was proven via insulin secretion experiments on isolated rat islets and was comparable to that of repaglinide. Finally, biodistribution of [(18)F]repaglinide was investigated in rats by measuring the concentration of the compound in different organs after i.v. injection. Pancreatic tissue displayed a stable accumulation of approximately 0.12% of the injected dose from 10 min to 30 min p.i. 50% of the radioactive tracer could be displaced by additional injection of unlabeled repaglinide, indicating that [(18)F]repaglinide might be suitable for in vivo investigation with PET.

Abstract
In very rare cases, salmonella infection may be associated with extra-intestinal manifestations. Of these, a mycotic aneurysm represents a life-threatening complication that is characterised by a high mortality rate. Prompt treatment with a combination of antibiotic therapy and surgical intervention is urgently required. We report on the case of a 60-year-old woman who presented with salmonella bacteraemia and the rare complication of an infected aneurysm of the ascending aorta and aortic arch.

Abstract
We present the results of a retrospective study on 56 patients who underwent the Sauve-Kapandji procedure for chronic disorders of the distal radioulnar joint (DRUJ). Outcome was assessed with special regard to the diagnosis. The average follow-up was 5.9 years (1-12 years). Patients were assessed for pain, range of motion of wrist and forearm, and radiological features. The DASH score and Mayo wrist score were used. The diagnosis had an influence on the outcome. Patients with primary arthrosis of the DRUJ demonstrated better results than patients with traumatic disorders. Patients with growth deficiency-related complaint of the DRUJ showed slightly inferior results after the Sauve-Kapandji procedure compared to all patients. Patients were free of pain or had pain only during heavy labor in 81% of cases; 95% of the patients rated the outcome as excellent or improved, but only 50% were free of symptoms on the operated side during heavy manual labor. Symptoms of ulnar impingement were found in 11%. Improvement in range of motion of wrist and forearm was significant. The postoperative DASH score was 24.2+/-22.5 and the Mayo wrist score was 76.1+/-17.6. Our results confirm the Sauve-Kapandji procedure to be a reliable salvage procedure resulting in high patient satisfaction and reliable improvement in range of motion. However, decreased grip strength on the affected side must be accepted to some extent. The diagnosis of a DRUJ disorder influences the outcome.

Abstract
AIMS The TOSCA project was set up to establish a tele-ophthalmology service to screen for diabetic retinopathy (DR) in Europe. The aim of this study was to determine the feasibility of establishing telemedicine-based digital screening for detecting DR and to evaluate the satisfaction of both patients and healthcare professionals with the screening procedures used within the TOSCA project. METHODS The study was a non-randomized, multicentre study carried out in four different countries over a period of 3 months. Patients (n = 390) with diabetes aged > 12 years were included. Two digital retinal images per eye (macular and nasal) were taken and exported to a central server. Patients were asked to complete a questionnaire to assess satisfaction. Accredited graders carried out grading remotely and the results were reported back to the referring centre. Previously graded patient data chosen randomly to represent examples of both DR and no DR were also sent anonymously to the grading centre at a frequency of approximately every 10 patients. RESULTS Most (99%) of the images were assessable enabling a retinopathy grade to be assigned to the patient. Patients found the retinal photography procedures acceptable; only 6% in one centre would not recommend the procedure. Healthcare professionals (photographers and graders) were also satisfied with the overall procedures. The average time taken to grade each patient was approximately 5 min. CONCLUSIONS This study demonstrated that it is feasible to electronically transmit and grade retinal images remotely using the TOSCA process. Built-in quality assurance procedures proved acceptable.

Abstract
In the quest for low-molecular-weight metal sulfur complexes that bind nitrogenase-relevant small molecules and can serve as model complexes for nitrogenase, compounds with the [Ru(PiPr(3))('N(2)Me(2)S(2)')] fragment were found ('N(2)Me(2)S(2)'(2-)=1,2-ethanediamine-N,N'-dimethyl-N,N'-bis(2-benzenethiolate)(2-)). This fragment enabled the synthesis of a first series of chiral metal sulfur complexes, [Ru(L)(PiPr(3))('N(2)Me(2)S(2)')] with L=N(2), N(2)H(2), N(2)H(4), and NH(3), that meet the biological constraint of forming under mild conditions. The reaction of [Ru(NCCH(3))(PiPr(3))('N(2)Me(2)S(2)')] (1) with NH(3) gave the ammonia complex [Ru(NH(3))(PiPr(3))('N(2)Me(2)S(2)')] (4), which readily exchanged NH(3) for N(2) to yield the mononuclear dinitrogen complex [Ru(N(2))(PiPr(3))('N(2)Me(2)S(2)')] (2) in almost quantitative yield. Complex 2, obtained by this new efficient synthesis, was the starting material for the synthesis of dinuclear (R,R)- and (S,S)-[micro-N(2)[Ru(PiPr(3))('N(2)Me(2)S(2)')](2)] ((R,R)-/(S,S)-3). (Both 2 and 3 have been reported previously.) The as-yet inexplicable behavior of complex 3 to form also the R,S isomer in solution has been revealed by DFT calculations and (2)D NMR spectroscopy studies. The reaction of 1 or 2 with anhydrous hydrazine yielded the hydrazine complex [Ru(N(2)H(4))(PiPr(3))('N(2)Me(2)S(2)')] (6), which is a highly reactive intermediate. Disproportionation of 6 resulted in the formation of mononuclear diazene complexes, the ammonia complex 4, and finally the dinuclear diazene complex [micro-N(2)H(2)[Ru(PiPr(3))('N(2)Me(2)S(2)')](2)] (5). Dinuclear complex 5 could also be obtained directly in an independent synthesis from 1 and N(2)H(2), which was generated in situ by acidolysis of K(2)N(2)(CO(2))(2). Treatment of 6 with CH(2)Cl(2), however, formed a chloromethylated diazene species [[Ru(PiPr(3))('N(2)Me(2)S(2)')]-micro-N(2)H(2)[Ru(Cl)('N(2)Me(2)S(2)CH(2)Cl')]] (9) ('N(2)Me(2)S(2)CH(2)Cl'(2-) =1,2-ethanediamine-N,N'-dimethyl-N-(2-benzenethiolate)(1-)-N'-(2-benzenechloromethylthioether)(1-)]. The molecular structures of 4, 5, and 9 were determined by X-ray crystal structure analysis, and the labile N(2)H(4) complex 6 was characterized by NMR spectroscopy.

Abstract
The aim of this experimental study was to measure the exact influence of torsional deformities at the middle third of the radial shaft before and after osteotomy of the ulnar shaft on the rotation of the forearm. Intact and fresh cadaver specimens were fixed in a newly developed apparatus that allowed free pronation and supination. A ring fixator was applied to the radial shaft with K wires that allowed torsional deformities to be stabilized in steps of 10 degrees. The middle of the radial shaft was osteotomized via a small soft tissue window leaving the other soft tissues including the interosseous membrane intact. Supination and pronation were measured using a goniometer in a standardized fashion. The mean supination value before osteotomy of the radius was 71.6 degrees [standard deviation (SD)15.2 degrees], the mean pronation value was 64.5 degrees (SD 12.4 degrees). Radial osteotomy caused no significant difference in the range of motion prior to creation of torsional deformities. Supination torsional deformities greater than 30 degrees showed a significant loss of pronation and pronation torsional deformities greater than 30 degrees resulted in a significant loss of supination in 14 fresh cadavers, respectively. The amount of mean rotational loss was approximately the same in the respective pronation and supination torsional deformities. In the next step the influence of an ulna osteotomy on the range of motion was evaluated in different torsional deformities. In the four cadavers measured, there was an increase of the range of motion in the direction of the torsional deformity. These values were not significant when compared to values before ulna osteotomy, but there were significant changes to the non deformity (p=0.004 for pronation, p=0.003 for supination). Impairment of range of motion in the opposite direction of the deformity showed a similar appearance as values before ulna osteotomy. Again, there were significant changes to the non deformity (p=0.003 for pronation, p=0.005 for supination).

Abstract
BACKGROUND Drugeluting stents (DES) are currently judged to be a "break-through" technology for the prevention of restenosis after percutaneous coronary interventions (PCI). However, experience is limited to randomised controlled clinical trials (RCT) in selected lesions and the currently available DES are more expensive compared to conventional "bare" stents. Therefore, actual clinical practice may be very different to RCT. METHODS We analysed the data of the German Cypher trade mark Registry, a nationwide registry which was initiated in parallel to the launch of the first DES, the Cypher trade mark sirolimus-eluting coronary stent, in April 2002. RESULTS From April 2002 until March 2003, 1638 procedures at 88 hospitals were included in the German Cypher trade mark Registry. The mean inclusion rate per centre and month remained low (<3 procedures/month and participating hospital) during the whole inclusion period. Most patients presented with stable angina pectoris (45.8%); however, 6.4% of patients were treated for a non-ST elevation myocardial infarction, 10.3% of patients for ST elevation myocardial infarction and 1.7% in cardiogenic shock. In patients without ST elevation myocardial infarction, a de novo stenosis was treated in 68.4% of cases, a restenosis in 4.1%, and an in-stent restenosis in 25.5% of cases. Chronic total occlusions were treated in 6.1% of patients. Predilatation was performed in 68.3% of patients and 1.05 +/- 0.35 Cypher trade mark stents were implanted per patient with a median (quartiles) stent length of 18 (13-21) mm. PCI-related death occurred in 0.1% of patients and a Q-wave myocardial infarction in 1.1%. Urgent re-PCI before hospital discharge was performed in 1.3% and urgent bypass surgery in 0.1% of cases. CONCLUSIONS The use of the sirolimus-eluting coronary stents in this "real life" registry was found to be safe concerning acute complications. In about one half of the registry patients, the DES was implanted in lesions that were excluded from RCTs.
