Abstract
AIMS To determine how patients with chronic wounds describe wound odour, identify what strategies they use to manage it and how effective these are. MATERIALS AND METHODS Using a qualitative descriptive approach, semi-structured interviews were conducted between July and August 2021 with seven patients living with an odorous chronic wound at home. Data were analysed using Braun and Clarke's thematic analysis framework. RESULTS The results were organised into two main themes: 1) becoming resigned to living with wound-related odour 2) strategies used to manage wound-related odour. Participants were sad, embarrassed and felt isolated but became resigned to living with this odour and accepting of it as a consequence of having a wound. Frequent dressing changes, household cleaning along with the use of sprays were the most frequently used tactics to manage odour none of which were deemed to be very effective. CONCLUSION This study highlights the problem of odour management in clinical practice and how individuals develop strategies to overcome odour. Sadly, patients were resigned to living with wound odour and were accepting of it as part of daily life. This highlights the importance for healthcare professionals to recognise, assess for and ensure a better understanding of how people experience wound odour, the impact it can have on them personally. Frequent dressing changes can help manage wound odour from the patient's perspective.

Abstract
Chronic wounds adversely affect the quality of life of individuals and odour is a well-recognised associated factor. Odour can affect sleep, well-being, social interactions, diet and potentially wound healing. This systematic review aims to examine the effectiveness of topical interventions in the management of odour associated with chronic and malignant fungating wounds. A systematic review guided by PRISMA recommendations of randomised controlled trials where odour intensity/odour is the primary outcome was undertaken. Inclusion criteria were adults (18 years and over) with chronic venous, arterial, diabetic or pressure ulcers or with malignant fungating wounds where odour has been managed through topical application of pharmacological/non-pharmacological agents. Searches were conducted in CENTRAL, CINAHL, EMBASE, MEDLINE, Scopus, and Web of Science. Eligibility screening, risk of bias assessment and data extraction was completed by authors working independently. Searches retrieved 171 titles and abstracts (157 post de-duplication). Thirteen studies were retained for full text review of which five (n = 137 individuals) examining the following treatments remained: metronidazole (n = 4), silver (n = 1). Meta-analysis was not possible but individual studies suggest improved outcomes (i.e., reduced odour) using metronidazole. Treatment options to manage wound odour are limited and hampered by lack of clinical trials, small sample sizes, and absence of standardised outcomes and consistent measurement. Whereas metronidazole and silver may have a role in controlling wound odour, robust and well-designed interventions with rigorous procedures and standardised odour outcomes are necessary to evaluate their contribution.

Abstract
BACKGROUND Ramucirumab and paclitaxel is the standard second-line therapy in patients with metastatic gastroesophageal adenocarcinoma. We report the efficacy and safety analyses of FOLFIRI and ramucirumab versus paclitaxel and ramucirumab after the failure of a platinum- and fluoropyrimidine-containing chemotherapy. METHODS This multicenter, investigator initiated, phase II trial randomised patients with gastroesophageal adenocarcinoma to either FOLFIRI plus ramucirumab (RAM) (arm A) or paclitaxel plus RAM (arm B). The primary end-point was 6-month overall survival (OS) rate, with a proportion of ≥65% in arm A considered a positive signal for further investigation. RESULTS 111 patients (65% of patients had prior docetaxel) were enrolled and 110 patients qualified for ITT population (arm A, 72; arm B, 38). The study did not meet the primary end-point for the comparison with historical control, as 6-month OS rate in the FOLFIRI plus RAM arm was 54% (95% CI 44-67). In between arm comparison, OS was similar (hazard ratio, HR 0.97 [95% CI 0.62-1.52]), while objective response rates (ORRs) and PFS were numerically better in arm A versus arm B (HR for PFS 0.73; ORR, 22% versus 11%). These differences were largely attributed to favourable efficacy results for arm A in docetaxel-pretreated patients (HR, 0.49; ORR, 25% versus 8%). In the safety population (n = 106), grade 3-5 adverse events were similar between arms (arm A, 75%; arm B, 68%). CONCLUSION The RAMIRIS trial demonstrated feasibility of FOLFIRI plus RAM. While the study was formally negative, it provided a signal to further investigate this combination for the group of patients with previous docetaxel therapy.

Abstract
INTRODUCTION Husbandry conditions for rabbits in Switzerland are at a high animal welfare level in international comparison. Wire mesh flooring is prohibited and group housing is mandatory up to the age of eight weeks. Despite these animal-friendly husbandry standards, animal losses seem to be a significant problem, although reliable data on professional Swiss meat rabbit production is lacking to date. A herd survey was carried out in 52 rabbit farms to address this situation. At the same time, each new litter and each fattening group was documented with a standardized form focusing on animal death and the use of medication by the farmer over a one year period. In the case of increased mortality or new health problems, dead rabbits were sent to the National Reference Center for Poultry and Rabbit Diseases (Zurich) for pathological examination including bacteriological and parasitological diagnostics. Data from 32 farms were evaluated. The average mortality of young animals (birth to weaning) was 14.9% (1.0-30.0%) and of fattening rabbits (weaning to slaughter) 17.3% (4.3-31.8%). Intestinal diseases, mainly dysentery, intestinal coccidiosis and mucoid enteropathies, were the primary cause of death (68.2%). Eimeria spp., Escherichia coli and Clostridium perfringens were identified as the most frequent pathogens. Respiratory diseases were found in 18.7% of the examined rabbits, with Pasteurella multocida identified as the most common pathogen. 60.0% of the farms used antibiotics during the study period and a third (34.7%) of all the fattening animals were medicated with at least one antibiotic. The present results confirm that despite high animal welfare standards infectious diseases and mortality rates represent a considerable problem in professional Swiss meat rabbit production. Risk factors of increased morbidity and mortality should be identified to improve rabbit health, to reduce the high mortality rate and the extensive use of antibiotics in professional Swiss meat rabbit production. Practicable management improvements with specific prevention strategies should be developed.

Abstract
BACKGROUND Venous leg ulcers (VLUs) are chronic wounds characterized by slow healing and high recurrence. Information on prevalence and incidence is essential for ascertaining the burden of VLU on the health care system and to inform epidemiological research, priority setting, and health care planning. The objective of this protocol is to present a transparent process for how we plan to review the existing international literature on the prevalence and incidence of VLU as well as the characteristics of the population reported within these studies. METHODS An exploratory search was performed using MEDLINE via PubMed and CINHAL via Ebsco to identify concepts, keywords, MeSH terms, and headings to identify study types looking at data of VLU prevalence and/or incidence and related patient characteristics. The findings of this exploratory search will determine the final search strategy. The titles and abstracts of the identified articles will be screened independently be two authors for relevance. Study which pass the quality assessment will be included. Data extraction will be performed independently by two authors and in accordance with a pre-designed data extraction form. If the data allows, a meta-analysis will be performed otherwise a descriptive summary of the findings will be conducted. DISCUSSION The results of this review will contribute to the evidence base on VLU occurrence and may inform the decision making of healthcare professionals, policy-makers, and consumers. It will also inform future research in this area of VLU care. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42020205855.

Type of funding sources: Foundation. Main funding source(s): Robert Bosch Stiftung; Deutsche Forschungsgemeinschaft
Background
Sudden cardiac death (SCD) is an appalling complication of hypertrophic cardiomyopathy (HCM). There is an ongoing discussion about the optimal SCD risk stratification strategy in HCM since established SCD risk models have suboptimal discriminative power.
Objective
To evaluate the prognostic value of late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) for SCD risk stratification compared to the ESC SCD risk score and traditional SCD risk factors in an >10-year follow-up study.
Methods
220 consecutive patients with HCM and LGE-CMR were enrolled. Follow-up data was available in 203 patients (median age 58 years, 61% male) after a median follow-up period of 10.4 years.
Results
LGE was present in 70% of patients with a median LGE amount of 1.6%, the median ESC 5-year SCD risk score was 1.84. In the overall cohort, SCD rates were 2.3% at 5 years, 4.8% at 10 years, and 15.7% at 15 years, independent from established risk models. A LGE amount of >5% (LV mass) portends the highest risk for SCD with SCD prevalences of 5.5% at 5 years, 13.0% at 10 years and 33.3% at 15 years. Conversely, patients with no or ≤5% LGE amount (of LV mass) have favorable prognosis.
Conclusions
LGE-CMR in HCM patients allows effective 10-year SCD risk stratification beyond established risk factors. LGE amount might be added to established risk models to improve its discriminatory power. Specifically, patients with >5% amount of LGE should be carefully monitored and might be adequate candidates for primary prevention ICD during the clinical long-term course.

Abstract
In agricultural settings, plant diversity is often associated with low biomass yield and forage quality, while biodiversity experiments typically find the opposite. We address this controversy by assessing, over 1 year, plant diversity effects on biomass yield, forage quality (i.e. nutritive values), quality-adjusted yield (biomass yield × forage quality), and revenues across different management intensities (extensive to intensive) on subplots of a large-scale grassland biodiversity experiment. Plant diversity substantially increased quality-adjusted yield and revenues. These findings hold for a wide range of management intensities, i.e., fertilization levels and cutting frequencies, in semi-natural grasslands. Plant diversity was an important production factor independent of management intensity, as it enhanced quality-adjusted yield and revenues similarly to increasing fertilization and cutting frequency. Consequently, maintaining and reestablishing plant diversity could be a way to sustainably manage temperate grasslands. Higher plant diversity in agricultural settings is often associated with lower biomass yield and with lower forage quality. Here, Schaub et al. show positive effects of plant diversity on biomass yield, quality-adjusted yield and revenues in semi-natural grassland across a range of management intensities.

Abstract
In EPR, spin relaxation is typically governed by interactions with the lattice or other spins. However, it has recently been shown that given a sufficiently strong spin-resonator coupling and high resonator quality factor, the spontaneous emission of microwave photons from the spins into the resonator can become the main relaxation mechanism, as predicted by Purcell. With increasing attention on the use of microresonators for EPR to achieve high spin-number sensitivity it is important to understand how this novel regime influences measured EPR signals, for example the amplitude and temporal shape of the spin-echo. We study this regime theoretically and experimentally, using donor spins in silicon, under different conditions of spin-linewidth and coupling homogeneity. When the spin-resonator coupling is distributed inhomogeneously, we find that the effective spin-echo relaxation time measured in a saturation recovery sequence strongly depends on the parameters for the detection echo. When the spin linewidth is larger than the resonator bandwidth, the different Fourier components of the spin echo relax with different characteristic times - due to the role of the resonator in driving relaxation - which results in the temporal shape of the echo becoming dependent on the repetition time of the experiment.

Abstract
Abstract
Background
Approximately 10% of patients with acute myocardial infarction do not have a culprit lesion. Such patients have been labelled as MINOCA (myocardial infarction with non-obstructive coronary arteries) and several pathophysiological etiologies have been described as potential explanations. This includes spontaneous coronary dissection, tako-tsubo-syndrome and coronary spasm. The latter can be diagnosed during invasive provocative testing. The aim of this study was to assess the frequency of coronary spasm and the safety of intracoronary provocation testing using acetylcholine in MINOCA patients compared to patients with stable angina and unobstructed coronary arteries.
Methods
Between 2007 and 2018 180 consecutive patients with either MINOCA or stable angina and unobstructed coronary arteries were enrolled. MINOCA was defined as acute onset of chest pain with either ST-segment elevation on the ECG or significant high sensitive troponin T elevation but no relevant epicardial stenosis (<50%) according to the current ESC guidelines. All patients underwent intracoronary acetylcholine provocation testing (ACH-test) in search of coronary spasm according to a standardized protocol immediately after diagnostic coronary angiography. Apart from systematic assessment of clinical, demographic and risk factor data, data regarding complications during the ACH-test were meticulously recorded.
Results
Eighty patients with MINOCA and 100 consecutive patients with stable angina were recruited (52% women, mean age 62±13 years). Overall, 59% had hypertension and 20% had diabetes. Comparison of clinical, demographic and risk factor data did not reveal any statistically significant differences except for a female preponderance in the stable patients (61% vs. 40%, p=0.007). The ACH-test revealed a coronary vasomotor disorder in 68% of cases. In 32% of cases the ACH-test was either inconclusive or negative. Epicardial spasm was found in 31% of patients with a higher prevalence among the MINOCA patients compared to the stable angina patients (41% vs. 23%, p=0.002). Microvascular spasm was found in 37% with a higher prevalence among the stable angina patients compared to the MINOCA cohort (49% vs. 23%, p=0.002). Assessment of complications during the ACH-test revealed that 13 MINOCA patients and 15 stable angina patients had minor complications such as intermittent atrioventricular block, sinusbradycardia, paroxysmal atrial fibrillation, ventricular ectopic beats or transient hypotension. Comparison of minor complications between the two groups did not reveal statistically significant differences (16% vs. 15%, p=0.839). None of the patients experienced any irreversible complications.
Conclusion
Coronary spasm is a frequent cause for MINOCA. Intracoronary spasm provocation testing using acetylcholine is feasible in such patients. The complication rate during ACH-testing in MINOCA patients is low and comparable to patients with stable angina.

Abstract
Background We have previously evidenced apical expression of the 24p3/NGAL/lipocalin-2 receptor (Lcn2-R; SLC22A17) in inner medullary collecting duct (IMCD) cells, which are present in vivo in a hyperosmotic/-tonic environment that activates canonical Wnt/β-catenin signaling. The localization of Lcn2-R in the inner medulla is intriguing considering local bacterial infections trigger toll-like receptor-4 (TLR-4)-mediated secretion of the bacteriostatic Fe3+-free (apo-)Lcn2. Aim To determine the effects of osmolarity/tonicity changes, Wnt/β-catenin and TLR-4 activation on Lcn2-R and Lcn2 expression and cell viability in rat primary IMCD and mouse (m)IMCD3 cells. Methods Normosmolarity/-tonicity was 300 mosmol/l whereas hyperosmolarity/-tonicity was induced by adding 100 mmol/l NaCl + 100 mmol/l urea (600 mosmol/l, 1-7 days). Lcn2-R and Lcn2 expression were determined by qPCR, immunoblotting, flow cytometry and immunofluorescence microscopy. β-catenin was silenced by RNAi. Cell viability/death was determined with MTT and LDH release assays. TLR-4 was activated by bacterial lipopolysaccharides (LPS). Results Hyperosmotic/-tonic media upregulated Lcn2-R by ~4-fold and decreased Lcn2 expression/secretion, along with Wnt/β-catenin activation, in IMCD cells. These effects of hyperosmotic/-tonic media on Lcn2-R/Lcn2 expression were reverted by normosmolarity/-tonicity, β-catenin silencing and/or LPS. Exposure of cells with endogenous or stably overexpressing Lcn2-R to apo-Lcn2 or LPS decreased cell viability. Conclusions Lcn2-R upregulation and Lcn2 downregulation via Wnt/β-catenin may promote adaptive osmotolerant survival of IMCD cells in response to hyperosmolarity/-tonicity whereas Lcn2 upregulation and Lcn2-R downregulation via TLR-4 and/or normosmolarity/-tonicity may protect IMCD cells against bacterial infections and prevent autocrine death induction by Lcn2.

Abstract
The renal proximal tubule (PT) is the major target of cadmium (Cd2+) toxicity where Cd2+ causes stress and apoptosis. Autophagy is induced by cell stress, e.g., endoplasmic reticulum (ER) stress, and may contribute to cell survival or death. The role of autophagy in Cd2+-induced nephrotoxicity remains unsettled due to contradictory results and lack of evidence for autophagic machinery damage by Cd2+. Cd2+-induced autophagy in rat kidney PT cell line NRK-52E and its role in cell death was investigated. Increased LC3-II and decreased p62 as autophagy markers indicate rapid induction of autophagic flux by Cd2+ (5-10 µM) after 1 h, accompanied by ER stress (increased p-PERK, p-eIF2α, CHOP). Cd2+ exposure exceeding 3 h results in p62/LC3-II accumulation, but diminished effect of lysosomal inhibitors (bafilomycin A1, pepstatin A +E-64d) on p62/LC3-II levels, indicating decreased autophagic flux and cargo degradation. At 24 h exposure, Cd2+ (5-25 µM) activates intrinsic apoptotic pathways (Bax/Bcl-2, PARP-1), which is not evident earlier (≤6 h) although cell viability by MTT assay is decreased. Autophagy inducer rapamycin (100 nM) does not overcome autophagy inhibition or Cd2+-induced cell viability loss. The autophagosome-lysosome fusion inhibitor liensinine (5 μM) increases CHOP and Bax/Bcl-2-dependent apoptosis by low Cd2+ stress, but not by high Cd2+. Lysosomal instability by Cd2+ (5 μM; 6 h) is indicated by increases in cellular sphingomyelin and membrane fluidity and decreases in cathepsins and LAMP1. The data suggest dual and temporal impact of Cd2+ on autophagy: Low Cd2+ stress rapidly activates autophagy counteracting damage but Cd2+ stress accrual disrupts autophagic flux and lysosomal stability, possibly resulting in lysosomal cell death.

Abstract
BACKGROUND AND AIMS With the debate over extent of lymphadenectomy in endometrial cancer, sentinel lymph node (SLN) mapping may provide a focused approach to evaluate the most relevant lymph nodes (LN) while minimizing the complications. We evaluated SLN mapping using filtered technetium(99), indocyanine green (ICG), and blue dye. METHODS Prospective evaluation of 100 patients who underwent SLN mapping by using submucosal and deep stromal cervical injections of technetium(99), ICG, and blue dye as part of the staging for endometrial cancer. RESULTS 286 SLNs were mapped (2.9 per patient) in 92% of patients. The bilateral detection rate was 76%. ICG had a significantly higher SLN detection rate than blue dye in both overall (87% vs 71%, respectively; p=0.005) and bilateral (65% vs 43%, respectively; p=0.002) detection, but similar SLN detection rates compared to technetium(99) in both overall (87% vs 88%, respectively; p=0.83) and bilateral (65% vs 71%, respectively; p=0.36) detection. In eight cases, the SLN was in the para-aortic area and in 14 cases in the pre-sacral, hypogastric vein, or parametrial area. In nine cases, the SLN was positive for metastasis, and in seven cases the SLN was the only positive node. One SLN was falsely negative. No complications or anaphylactic reactions occurred. CONCLUSION Intra-operative SLN mapping using cervical injection is feasible in patients with endometrial cancer and yields adequate detection rates. It allows mapping of SLNs in areas (pre-sacral, hypogastric vein, parametrial) not routinely sampled. Given the poorer performance of blue dye, surgeons may omit its use if a combination of ICG and technetium(99) is used.

Abstract
Superconducting microwave resonators are reliable circuits widely used for detection and as test devices for material research. A reliable determination of their external and internal quality factors is crucial for many modern applications, which either require fast measurements or operate in the single photon regime with small signal to noise ratios. Here, we use the circle fit technique with diameter correction and provide a step by step guide for implementing an algorithm for robust fitting and calibration of complex resonator scattering data in the presence of noise. The speedup and robustness of the analysis are achieved by employing an algebraic rather than an iterative fit technique for the resonance circle.

Abstract
Non-healing wounds are a significant problem for health-care systems worldwide. In the industrialised world, almost 1-1.5% of the population will have a problem wound at any one time. Furthermore, wound management is expensive; in Europe, the average cost per episode is 6650 euros for leg ulcers and 10 000 euros for foot ulcers, and wound management accounts for 2-4% of health-care budgets. These figures are expected to rise along with an increased elderly and diabetic population.1-4.

Abstract
Interfacing photonic and solid-state qubits within a hybrid quantum architecture offers a promising route towards large scale distributed quantum computing. Ideal candidates for coherent qubit interconversion are optically active spins, magnetically coupled to a superconducting resonator. We report on an on-chip cavity QED experiment with magnetically anisotropic Er(3+)∶Y2SiO5 crystals and demonstrate collective strong coupling of rare-earth spins to a lumped element resonator. Moreover, the electron spin resonance and relaxation dynamics of the erbium spins are detected via direct microwave absorption, without the aid of a cavity.

Abstract
4545 Background: The combination of docetaxel, cisplatin, and fluorouracil (DCF) is clearly superior to CF in the treatment of patients (pts) with advanced gastric cancer (AGC). DCF is, however, associated with significant toxicity, including neutropenia, febrile neutropenia, diarrhea and mucositis. This study evaluated a biweekly, oxaliplatin-based modification of DCF. Methods: Pts with measurable, locally advanced or metastatic adenocarcinoma of the stomach or GE-junction and no prior chemotherapy received mFOLFOX (oxaliplatin 85 mg/sqm, leucovorin 200 mg/sqm, and fluorouracil 2.6 g/sqm via 24hr infusion) in combination with docetaxel 50 mg/sqm on day 1 every 2 weeks (FLOT-regimen). Prophylactic G-CSF was not administered. Overall response rate (RR) was the primary endpoint (power 80% to detect a RR of >40%) and toxicity profile the main secondary endpoint. The study was externally monitored according to GCP and data were reviewed by an independent safety board. Results: 59 pts (male, 41; female, 18) were enrolled. At the time of analysis, 53 pts were evaluable for toxicity and 51 pts for response. Median age was 60 (range, 29–76), median ECOG PS was 1, and almost all (93%) pts had metastatic disease. Of 51 pts, 2 had a CR and 25 pts attained a PR, adding to an overall RR of 53% (ITT-analysis). Stable disease was observed in 12 (23.5%) and progressive disease in 6 (11.8%) pts. Six (11.8%) pts were not evaluable for response. NCI-CTC grade 3 or 4 hematologic toxicity included leukopenia in 12 (22.6%), neutropenia in 23 (43%), and anemia in 2 (3.8%) pts. Febrile neutropenia was observed in 1 (1.9%) pt only. Other grade 3 or 4 toxicities included peripheral neuropathy in 4 (7.5%), nausea in 3 (5.7%), vomiting in 2 (3.8%) as well as diarrhea and fatigue in 5 (9.4%) pts each. No treatment related deaths were observed. Conclusions: FLOT is active and has a favorable toxicity profile in the treatment of pts with AGC. It may show activity also in perioperative treatment settings and may be considered as a useful treatment option for elderly pts. Survival data will be presented at the meeting. [Table: see text]

Abstract
LBA4016 Background: Cisplatin-based chemotherapy is a standard option in advanced gastric cancer. However, treatment results have been unsatisfactory so far, with a time to progression (TTP) of 3 to 4 months and an overall survival (OS) of 6 to 9 months. In addition, treatment regimens are too intense and toxicity is considerable. The aim of this 2-arm randomized trial was to determine whether FLO prolongs TTP and reduces toxicity as compared to FLP. Methods: Patients (pts) were randomized to receive FLO: F 2600 mg/m2 24 h infusion, L 200 mg/m2, and oxaliplatin 85 mg/m2, every two weeks or FLP: F 2000 mg/m2 24 h infusion, L 200 mg/m2, weekly, and cisplatin 50 mg/m2, every two weeks. The primary end point was TTP. Main secondary endpoints included toxicity, time to treatment failure (TTF), and OS. Based on a planned sample size of 218 pts, the trial was designed to have an 80% power to detect an improvement in median TTP from 3.5 to 5.0 months (1-sided log-rank test; significance level 0.05). Results: 220 pts (FLO/FLP, 112/108) were randomized between Aug 2003 and Jan 2006. Median age was 64 yrs and median ECOG was 1. 162 pts (FLO, 80; FLP, 81) had disease progression and 25 pts (FLO, 18; FLP, 8) are still under treatment. Median TTP was 5.7 months for FLO and 3.8 months for FLP (log-rank p = 0.081, Wilcoxon p = 0.019). Median TTF was 5.3 months for FLO and 3.1 months for FLP (log-rank p = 0.028). Response to FLO (34%) was superior to FLP (27%), with 15% and 30% of pts having disease progression as best response to FLO and FLP, respectively (chi-square for trend p = 0.012). Median treatment duration was 4.3 months with FLO and 3 months with FLP. FLO was associated with significantly less NCI-CTC grade 1–4 leukopenia, nausea, alopecia, fatigue, and renal toxicity and FLP was associated with significantly less peripheral neuropathy (chi-square for trend p < 0.05). Severe adverse events related to treatment were less frequent with FLO (8.9%) as compared to FLP (18.6%; p = 0.046). Conclusions: FLO reduced toxicity and improved efficacy as compared to FLP. This leads us to consider FLO for future studies in combination with targeted drugs to further improve the outcome of pts with gastric cancer. No significant financial relationships to disclose.

Abstract
Differences in word processing between adult developmental dyslexic (n = 12) and normal readers (n = 12) were studied using event-related brain potentials recorded while subjects performed a recognition memory task. During the first part of the experiment, words were presented consecutively, and within this phase one third of the words were repeated. Subjects had to indicate whether a given word had previously been seen or not. After a delay of 1 hr, a second phase was administered. Here, another list containing 33% old words (presented in Phase 1) and 66% new words was shown and an old/new decision was required. In both categories, half of the words presented in either phase were of high normative frequency, and the other half were of low-frequency in the German language. Recognition performance was superior in normal readers for both high- and low-frequency words. In Phase 1, a fronto-centrally distributed N400 repetition effect discriminated between correctly identified old and new words (new words more negative). This effect was present for dyslexic as well as normal readers and for high- and low-frequency words. Between 450 and 800 ms, a 'P600 old/new effect' emerged (ERPs evoked by old words were more positive than those for new words). This effect was larger for low-frequency words. In Phase 2, an old/new effect was obtained for normal readers only. These findings are discussed in relation to current concepts of dyslexia and of semantic processing.

Abstract
We report on a patient who suffered a large subcapsular and perirenal haematoma after extracorporeal shockwave lithotripsy. Despite surgical intervention the bleeding did not stop for 6 days and 10 units of packed red blood cells were transfused. With the treatment of recombinant, activated factor VIII (NovoSeven((R))) an immediate haemostasis could be reached, so that impending nephrectomy could be avoided. This is the first case where FVIIa has been successfully used to stop a trauma-related bleeding in a patient without any obvious accompanying coagulation disorder.

Abstract
Despite almost forty years of widespread use, the mode of action of antidepressant drugs is still largely unknown. There is agreement that these drugs interact with central neurotransmission. Common findings are acute inhibitory actions on reuptake mechanisms for norepinephrine (NE) and for serotonin (5-HT) at presynaptic axons and chronic adaptive effects on neurotransmitter receptors on postsynaptic membranes. In particular, beta-adrenoceptor downregulation has been observed after chronic treatment with most antidepressants in vivo and in cell culture systems. We studied the effectiveness of Ze 117 (St. John's wort) extract (Hypericum perforatum) on NE- and 5-HT-uptake into rat brain slices. Potency and efficacy of the Ze 117 extract were compared with those of tricyclic (TCA) and selective serotonin reuptake inhibitor (SSRI)-type antidepressants. A dose-dependent inhibition was seen on NE and 5-HT uptake into brain slices. The Ze 117 extract was more selective for the uptake of NE than for that of 5-HT. The maximal extent of uptake inhibition by Ze 117 extract was comparable to that of imipramine (IMI), desipramine (DMI) or fluvoxamine for 5-HT, but lower for NE transport, than that of the synthetic antidepressants. Chronic exposure (8 days) of confluent C6-cell cultures to Ze 117 extract resulted in a dose-dependent beta-adrenoceptor downregulation equal to that induced by DMI, a potent TCA. None of these effects could be achieved with either hypericin or hyperforin alone in a relevant dose range. Our results indicate that the St. John's wort extract Ze 117 contains active, but as yet unknown antidepressant principles with effects comparable to those of TCAs.

Abstract
This study tests whether lead deposited to soil from automobiles during past years in a medium-sized US city (population 150,000) may present a current health risk. It examines the relationship between current soil lead concentrations at nine locations within the city of Springfield, Missouri, and airborne lead levels measured at the same locations during years (1975-1981) when lead emissions from automobiles were much greater than at present. A strong, significant correlation is found between soil and airborne lead levels at eight of the sites (r = 0.91, P < 0.005 for soil lead vs. 1979 airborne lead), in low-traffic areas as well as in areas adjacent to heavy traffic flow. Residual lead concentrations in these soils are relatively low, even for the high-traffic sites, as expected for a medium sized city.

Abstract
In asymptomatic infertility patients, no significant relationship was found between the presence of antisperm antibodies (ASA) in serum and in semen samples (IgG and/or IgA ASA), differentiated with the mixed antiglobulin reaction (MAR), and the microbial colonization of ejaculates covering a broad spectrum of microorganisms. Likewise, there was no significant association of ASA with microbial findings in patients' female partners, who also presented without symptoms of genital tract infection and were screened at the same time. Furthermore, ASA in semen (IgG and IgA) were not significantly related to several potential markers of subclinical male sexual gland infection or inflammation (leukocytes, PMN elastase, albumin, C3c) evaluated in aliquots of the same ejaculates used for immunological testing.
