Abstract
Critically ill patients are at risk for sepsis, and immunosuppressive mechanisms may prevail. Whether functional tests are helpful to detect immune alterations is largely unknown. Therefore, we tested the hypotheses that reactivity of peripheral blood mononuclear cells (PBMCs) to secrete interferon-γ (IFNγ) following stimulation in vitro is decreased in patients with early sepsis compared with postoperative patients. IFNγ secretion [enzyme-linked immunospot (ELISpot)] in response to stimulation with cytomegalovirus (CMV), pokeweed mitogen (PWM), muromonab-anti-CD3 (OKT3), and human leukocyte antigen (HLA)-DRA-mRNA expression and serum cytokine concentrations were repeatedly [days 1, 3, 5, and 7 after intensive care unit (ICU) admission] determined in patients with sepsis (n = 7) and patients undergoing major abdominal surgery (radical prostatectomy, cystectomy, n = 10). In a second cohort, HLA-DRA expression was assessed in 80 patients with sepsis, 30 postoperative patients, and 44 healthy volunteers (German clinical trials database no. 00007694). In patients with sepsis, IFNγ secretion (ELISpot) was decreased compared with controls after stimulation with CMV (P = 0.01), OKT3 (P = 0.02), and PWM (P = 0.02 on day 5), whereas unstimulated IFNγ secretion did not differ. HLA-DRA expression was also significantly decreased in patients with sepsis at all time points (P = 0.004) compared with postoperative surgical patients, a finding confirmed in the larger cohort. Reactivity of PBMCs to stimulation with CMV, PWM, and OKT3 as well as HLA-DRA expression was already decreased upon ICU admission in patients with sepsis when compared with postoperative controls, suggesting early depression of acquired immunity. ELISpot assays may help to clinically characterize the time course of immunocompetence in patients with sepsis.NEW & NOTEWORTHY We observed suppression of reactivity to stimulation with cytomegalovirus, muromonab-anti-CD3, and pokeweed mitogen in mononuclear blood cells of patients with early sepsis when compared with postoperative controls. Thus, there is early depression of acquired immunity in sepsis. Enzyme-linked immunospot assays may help to characterize immunocompetence in patients with sepsis.

Abstract
Atoms start behaving as waves rather than classical particles if confined in spaces commensurate with their de Broglie wavelength. At room temperature this length is only about one ångström even for the lightest atom, hydrogen. This restricts quantum-confinement phenomena for atomic species to the realm of very low temperatures1-5. Here, we show that van der Waals gaps between atomic planes of layered crystals provide ångström-size channels that make quantum confinement of protons apparent even at room temperature. Our transport measurements show that thermal protons experience a notably higher barrier than deuterons when entering van der Waals gaps in hexagonal boron nitride and molybdenum disulfide. This is attributed to the difference in the de Broglie wavelengths of the isotopes. Once inside the crystals, transport of both isotopes can be described by classical diffusion, albeit with unexpectedly fast rates comparable to that of protons in water. The demonstrated ångström-size channels can be exploited for further studies of atomistic quantum confinement and, if the technology can be scaled up, for sieving hydrogen isotopes.

Abstract
The production of pure deuterium and the removal of tritium from nuclear waste are the key challenges in separation of light isotopes. Presently, the technological methods are extremely energy- and cost-intensive. Here we report the capture of heavy hydrogen isotopes from hydrogen gas by selective adsorption at Cu(I) sites in a metal-organic framework. At the strongly binding Cu(I) sites (32 kJ mol-1) nuclear quantum effects result in higher adsorption enthalpies of heavier isotopes. The capture mechanism takes place most efficiently at temperatures above 80 K, when an isotope exchange allows the preferential adsorption of heavy isotopologues from the gas phase. Large difference in adsorption enthalpy of 2.5 kJ mol-1 between D2 and H2 results in D2-over-H2 selectivity of 11 at 100 K, to the best of our knowledge the largest value known to date. Combination of thermal desorption spectroscopy, Raman measurements, inelastic neutron scattering and first principles calculations for H2/D2 mixtures allows the prediction of selectivities for tritium-containing isotopologues.

Abstract
We present the effect of different stacking orders on carrier transport properties of multi-layer black phosphorous. We consider three different stacking orders AAA, ABA and ACA, with increasing number of layers (from 2 to 6 layers). We employ a hierarchical approach in density functional theory (DFT), with structural simulations performed with generalized gradient approximation (GGA) and the bandstructure, carrier effective masses and optical properties evaluated with the meta-generalized gradient approximation (MGGA). The carrier transmission in the various black phosphorous sheets was carried out with the non-equilibrium green's function (NEGF) approach. The results show that ACA stacking has the highest electron and hole transmission probabilities. The results show tunability for a wide range of band-gaps, carrier effective masses and transmission with a great promise for lattice engineering (stacking order and layers) in black phosphorous.

Abstract
OBJECTIVES The aim of this cross-sectional study was to examine the influence of age and sex on neuromuscular function of the lower limbs using mechanography. 704 adults aged 20-85 years from Germany participated in this study. METHODS Ground reaction force and power were assessed with countermovement jumps and the chair rising test on a ground reactions force plate. RESULTS While ground reaction force per unit body mass declined by about 20% from the third to the ninth decade, the decline of power per unit body mass was much greater, varying between 40-50%. Men and women are affected equally by the decline. Age and sex explained the variability of the power parameters to a much greater extent (R(2)=0.54 to R(2)=0.70) than the force parameters (R(2)=0.18 to R(2)=0.36). CONCLUSIONS Our reference values can help to identify those who might be affected by the development of sarcopenia. Preventive exercise programs should focus on preserving muscle power in addition to the training of muscle force.

Abstract
A 48-year-old man presented with recurrent bronchopulmonary infections of many years' standing. The diagnosis of tracheobronchomegaly (Mounier-Kuhn syndrome) was based on CT examination and subsequent bronchoscopy. Since lung transplantation was not considered advisable, a biluminal stent was inserted to prevent bronchial collapse.

Abstract
Micromolar concentrations of the biologically active oestrogen 17beta-oestradiol reduce agonist-induced force in vascular preparations through an unidentified mechanism. The aim of the present study was to investigate the importance of oestrogen receptor beta (ERbeta) for oestrogen-induced vascular relaxation. 17beta-oestradiol was added to aortic rings from ERbeta knock-out (-/-) and wild-type (+/+) mice precontracted with noradrenaline. 17beta-oestradiol caused a concentration-dependent (1-100 microM) relaxation of aortic rings from both -/- and +/+ animals of both sexes. Rings from male and female -/- mice were more sensitive to 17beta-oestradiol than those from +/+ mice. Medial thickness, determined by computerized image analysis, was similar in rings from -/- and +/+ animals. Endothelium, as determined by immuno-cytochemistry, was present in -/- and +/+ aorta. Maximal noradrenaline evoked force and sensitivity to noradrenaline were similar in both groups. In summary ERbeta modulates vascular relaxation to microM concentrations of oestrogen; lack of ERbeta renders the vascular wall supersensitive to 17beta-oestradiol. Lack of ERbeta caused no change in vascular wall morphology suggesting that this ER subtype is not involved in vascular structure development.

Abstract
PURPOSE To investigate the efficiency of preoperative autologous deposit and intra- and postoperative cell salvage (CS) to reduce homologous transfusion in hip arthroplasty and revision hip arthroplasty. METHODS In a retrospective study, the data of 1402 patients scheduled for hip arthroplasty and for revision hip arthroplasty were analysed. RESULTS 767 women and 635 men, age 62.9 +/- 9.8 years (x +/- s) were included in the study. 1270 were scheduled for hip arthroplasty, 132 for revision hip arthroplasty. Of the autologous donors, 51 patients predeposited four units, 1020 patients three, 204 patients two, 39 patients one unit. 88 patients who had not enrolled in the autologous donation program but received CS served as a control group. Blood loss in autologous donors amounted to 1620 (220-5620) ml in hip arthroplasty and 2830 (950-7910) ml in revision arthroplasty. CS was employed in part of the cases in arthroplasty and in all revision operations. 470 (0-2200) ml and 705 (0-2200) were retransfused. In hip arthroplasty 227 of 1182 patients (19.2%) received homologous blood. Homologous transfusion in patients with coxarthrosis due to acetabular protrusio, avascular necrosis of the femoral head and hip dysplasia showed a trend to higher values. Patients who had donated 3 units and received CS required homologous transfusion in 12.4% of the cases. CS reduced the homolgous transfusion rate significantly if the preoperative hemoglobin concentration was < or = 12 g/dl. A group of autologous donors receiving CS was matched with patients receiving CS only. 12 of 76 (15.8%) vs. 45 of 76 (59.2%) required homologous transfusion. In revision hip arthroplasty 58 of 132 patients (43.9%) required homologous blood. CONCLUSIONS Preoperative deposit reduces homologous transfusion requirements considerably in hip surgery. Under the conditions studied CS should be employed in hip arthroplasty in addition to preoperative deposit if the preoperative hemoglobin concentration falls below 12 g/dl. In revision arthroplasty, 4 or more autologous units should be predeposited and CS should be used regularly.

Abstract
Since there are now several ways to treat symptomatic gallstone disease, one is able to select treatment on the basis of the patient's comfort, the practicability, effectiveness, and side effects of the technique, and the relative costs. In order to assess the present status of contact dissolution with methyl tert-butyl ether with regard to these aspects, the present enquiry reports the data of 21 European hospitals. Eight hundred three patients were selected for contact litholysis of cholesterol gallbladder stones using methyl tert-butyl ether. Percutaneous transhepatic puncture of the gallbladder was performed under x-ray or ultrasound guidance. Dissolution rate, side effects, and treatment times of 268 patients from one single center were compared to those of 535 patients from the other 20 centers. Two hundred sixty-four patients were followed for five years to assess stone recurrence. Physicians were asked how they assessed the expenditure of the method, the discomfort to the patients, and the staffing situation. Patients were asked to indicate their acceptance on an analog scale. Puncture was successful in 761 (94.8%) patients. Prophylactic administration of antibiotics was not necessary. Stones were dissolved in 724 (95.1%) patients. In 315 (43.5%) sludge remained in the gallbladder. The most severe complication was bile leakage, which led 12 (1.6%) patients to have elective cholecystectomy. Toxic injuries due to the ether were not reported. Method-related lethality amounted to 0%, 30-day-lethality to 0.4%. Stone recurrence rate was about 40% in solitary stones and about 70% in multiple stones over five years. Patients with multiple stones developed recurrent stones almost twice as often as those with solitary stones. The probability of stone recurrence in patients with sludge in the gallbladder after catheter removal was not statistically significantly different from those without sludge. Seventy to 90% of the centers found the puncture to be simple and not distressing for patients and the relation between expenditure and therapeutic success to be acceptable. The acceptance of contact litholysis by the patients was excellent. Contact litholysis when applied by an experienced team provides real advantages in the treatment of gallstone disease. The method is technically simple, well accepted by the patients, and can be easily applied in community hospitals. Contact litholysis may be of particular value in patients who are not suitable for anesthesia or surgery.

Abstract
A clinico-experimental investigation was conducted to study subjects exposed to neurotoxic pollutants and contaminants by means of the Combitest 2 computer-aided psychometric method. To this end, sensopsychomotor, mnestic and intellectual performance as well as concentration power were evaluated. Single and multiple choice reaction tasks, termometer tracking and maximal tapping were found to be efficient screening methods. Pronounced relationships were seen to exist between psychometric test results and lead concentration levels in blood.
