Abstract
BACKGROUND AND OBJECTIVE The internet provides numerous sources of information about prostate cancer (PCa). The present study investigated internet use among long-term PCa survivors, trust in online PCa-related information, and associated factors. MATERIALS AND METHODS Based on the German national research project Familial Prostate Cancer long-term PCa survivors were asked about their internet use in 2017. Associations with sociodemographic (age at survey, children, intimate relationship, education) and disease-related parameters (time since diagnosis, PCa family history, progress) were analyzed using multivariable logistic regression. RESULTS In all, 4636 long-term PCa survivors were included in the analysis (mean age 76.9 years; standard deviation 6.6 years). Mean follow-up was 14.0 years. Of long-term PCa survivors, 62.1% were using the internet. Among non-users 23.5% expressed strong concerns, among users only 2.8%. Furthermore, 47.2% of internet users sought information about PCa, 18.0% of them indicated difficulties while searching for information. More than half of the users found the online information inappropriate. Lower age, shorter time since diagnosis, progress, and a more frequent internet use were associated with search for information. Only one-third fully trusted online information. Trust in online information was associated with high age, higher educational level, and frequent search for online information. Many survivors stressed that they were primarily trusting their treating urologist. CONCLUSIONS Two-thirds of long-term PCa survivors are using the internet. A significant proportion expressed difficulties finding proper and reliable information. Urologists should be familiar with online resources on PCa in order to offer advice to patients and to recommend adequate information on the internet.

Abstract
BACKGROUND Self-concept consists of self-perceptions and is influenced by the life course of the person. OBJECTIVES This study investigated associations between self-concept and erectile dysfunction (ED) in 45-year-old German men. MATERIALS AND METHODS Forty-five-year-old, heterosexual men who had participated in the PROBASE-study were included. Erectile Function was evaluated using the International Index of Erectile Function (IIEF-6). The presence of ED was defined by IIEF-6 score ≤ 25. Self-concept was assessed using the facets "body image" (three items from the Dresden Body Image Inventory, DKB-35), "perception of masculinity" (three items from the Male Role Norms Scale, MRNS), "perceived social pressure with regard to sexual performance" (four newly constructed items), and "sexual self-esteem" (three newly constructed items). Scores for these facets of self-concept can range from 1 to 5. Higher scores indicate a more positive body image, higher sexual self-esteem, a more modern understanding of masculinity, and greater perceived social pressure. Differences in self-concept between men with ED and without ED were analyzed using the Mann-Whitney-U-test. Furthermore, Cohen's d effect sizes (ES d) were calculated. RESULTS The responses of 3143 men were analyzed. Men with ED (16.2 %) have significantly lower scores regarding body image (mean 3.6 ± 0.6 vs 3.8 ± 0.5; p < 0.001; ES d = -0.5), perception of masculinity (mean 3.4 ± 0.7 vs 3.7 ± 0.6; p < 0.001; ES d = -0.4), and sexual self-esteem (mean 3.6 ± 0.6 vs 3.9 ± 0.5; p < 0.001, ES d = -0.4) than men without ED. Furthermore, they had significantly higher scores for perceived social pressure (mean 2.1 ± 0.7 vs 1.5 ± 0.5; p < 0.001; ES d = 1.2). CONCLUSIONS Self-concept and ED are associated in 45-year-old men. Men with ED have a more negative body image, a more traditional understanding of masculinity, more negative sexual self-esteem, and greater perceived social pressure with regard to sexual performance than men without ED.

Abstract
BACKGROUND Good communication is a core competency for all physicians. Thus, medical students require adequate preparation in communication skills. For research purposes, as well as for evaluation in teaching, there is a clear need for reliable assessment tools. We analyzed the shortcomings of existing instruments and saw a need for a new rating scale. The aim of this publication is to describe the development process for, and evaluation of, a new rating scale. METHODS First, we developed the rating scale in 10 steps. Then, two raters evaluated the newly developed rating scale by rating 135 videotaped consultations of medical students with standardized patients. Additionally, standardized patients evaluated students' performance, which was used as an outside criterion to validate ratings. RESULTS Our rating scale comprises six domains with 13 specific items evaluated on a five-point Likert scale: initiating conversation, patient's perception, structure of conversation, patient's emotions, end of conversation, and general communication skills. Item-total correlation coefficients between the checklist items ranged from 0.15 to 0.78. Subscale consistency was calculated for domains comprised of more than one item and Cronbach's α ≥ 0.77, indicating acceptable consistency. Standardized patients' global evaluation correlated moderately with overall expert ratings (Spearman's ρ = .40, p < .001). CONCLUSION Our rating scale is a reliable and applicable assessment tool. The rating scale focuses on the evaluation of general communication skills and can be applied in research as well as in evaluations, such as objective structured clinical examinations (OSCE). ABBREVIATIONS CST: Communication skills training; ICC: Intra-class correlation coefficient; OSCE: Objective structured clinical examination; SP: Standardized patients; SD: Standard deviation; M: Mean.

Abstract
BACKGROUND Anorexia nervosa (AN) is a serious illness leading to substantial morbidity and mortality. The treatment of AN very often is protracted; repeated hospitalizations and lost productivity generate substantial economic costs in the health care system. Therefore, this study aimed to determine the differential cost-effectiveness of out-patient focal psychodynamic psychotherapy (FPT), enhanced cognitive-behavioural therapy (CBT-E), and optimized treatment as usual (TAU-O) in the treatment of adult women with AN. METHOD The analysis was conducted alongside the randomized controlled Anorexia Nervosa Treatment of OutPatients (ANTOP) study. Cost-effectiveness was determined using direct costs per recovery at 22 months post-randomization (n = 156). Unadjusted incremental cost-effectiveness ratios (ICERs) were calculated. To derive cost-effectiveness acceptability curves (CEACs) adjusted net-benefit regressions were applied assuming different values for the maximum willingness to pay (WTP) per additional recovery. Cost-utility and assumptions underlying the base case were investigated in exploratory analyses. RESULTS Costs of in-patient treatment and the percentage of patients who required in-patient treatment were considerably lower in both intervention groups. The unadjusted ICERs indicated FPT and CBT-E to be dominant compared with TAU-O. Moreover, FPT was dominant compared with CBT-E. CEACs showed that the probability for cost-effectiveness of FTP compared with TAU-O and CBT-E was ⩾95% if the WTP per recovery was ⩾€9825 and ⩾€24 550, respectively. Comparing CBT-E with TAU-O, the probability of being cost-effective remained <90% for all WTPs. The exploratory analyses showed similar but less pronounced trends. CONCLUSIONS Depending on the WTP, FPT proved cost-effective in the treatment of adult AN.

Abstract
OBJECTIVE Patients' processing of psychotherapy between sessions ("inter-session process" (ISP)) has been repeatedly shown to be related to outcome. The aim of this study was to compare ISP characteristics of cognitive-behavioral vs. psychodynamic psychotherapy in the treatment of anorexia nervosa (AN) and their relation to outcome. METHODS Data of 106 patients participating in a randomized-controlled trial who received either 40 sessions of enhanced cognitive-behavioral therapy (CBT-E) or focal psychodynamic therapy (FPT) were analyzed. The ISP was measured with the Inter-session Experience Questionnaire (IEQ). Three outcome classes were distinguished: full recovery, partial recovery, and still fulfilling all AN criteria. RESULTS Patients receiving CBT-E reported more on "applying therapy" in the initial and the final treatment phase compared to FPT patients. In terms of process-outcome relations, higher levels of "recreating the therapeutic dialogue between sessions," "recreating the therapeutic dialogue with negative emotions" as well as "applying therapy with negative emotions" in the final phase of treatment predicted negative outcome in FPT, whereas overall higher levels of negative emotions predicted negative outcome in CBT-E. CONCLUSIONS In outpatient treatment in AN, the processing of therapy as measured by the IEQ showed surprisingly few differences between CBT-E and FPT. However, different ISP patterns were predictive of outcome, pointing to different mechanisms of change.

Abstract
BACKGROUND Patient counseling by using the IIEF to assess erectile function (EF) before and after radical prostatectomy (RPX) is only possible under limited circumstances. The aim of this study was to evaluate if the Erection Hardness Score (EHS) could be used in addition to the IIEF for the assessment of EF and patient preference regarding counseling for their sex life. MATERIAL AND METHODS EF was evaluated in 307 patients 3-60 months after RPX using the IIEF-EF and EHS. Questionnaires assessed sexual activity/intercourse as well as satisfaction with sex life irrespective of EF (10-point Likert scale). Patients were further asked concerning development of new sexual methods independent of erection firm enough for penetration and further wishes regarding counseling for their sex life. RESULTS Of 272 patients, 82.0% underwent bilateral nerve-sparing prostatectomy, 30.5% (n=83; mean age: 68.1 years) had sexual intercourse and 41.9% (n=114) were sexually active. EH Scores 1-2 and 4 coincided with compatible IIEF-EF Scores 1-21, and ≥ 26, respectively. Of the patients with an EHS of 3, 55.9% had an IIEF-EF score that was notably lower. Of patients with sexual intercourse, 65.8% were satisfied with their sex life; 53.2% of sexually active patients were satisfied without sexual intercourse. Alternative methods were manual/oral stimulation, cuddling, and the use of vibrators. Patients request individually tailored, realistic counseling. CONCLUSION The advantage of the EHS compared to the IIEF is that the erectile function can be assessed irrespective of sexual intercourse and sexual partner. Counseling should assist patients towards the attainment of a satisfying sex life-even without an erection.

Abstract
PURPOSE To report on chronic adverse events (CAE) and quality of life (QOL) after radiochemotherapy (RCT) in patients with anal cancer (AC). PATIENTS AND METHODS Of 83 patients who had received RCT at our department between 1988 and 2011, 51 accepted the invitation to participate in this QOL study. CAE were evaluated using the Common Terminology Criteria for Adverse Events (CTCAE) v. 4.0 and QOL was assessed with the Functional Assessment of Cancer Therapy-Colorectal (FACT-C) questionnaire. RESULTS CAE could be evaluated in 49 patients. There was a tendency toward a higher rate of grade 3 CAE in female patients, i.e. 18 out of 37 (49 %) vs. 2 out of 12 (17 %) male patients (p = 0.089). The most common grade 3 CAE were dyspareunia and vaginal symptoms (itching, burning and dryness) in 35 and 22 % of female patients, respectively, followed by stool incontinence in 13 % of all patients (6 out of 49). Both FACT-C and CAE information were available for 42 patients, allowing evaluation of the impact of CAE on QOL. The median total FACT-C score was 110 (40-132) out of a possible maximum of 136. The absence of grade 3 CAE (115 vs. 94, p = 0.001); an interval of ≥ 67 months after the end of the treatment (111 vs. 107, p = 0.010), no stool incontinence vs. grade 3 stool incontinence (111 vs. 74, p = 0.009), higher education (114 vs. 107, p = 0.013) and no dyspareunia vs. grade 3 dyspareunia (116 vs. 93, p = 0.012) were significantly associated with a higher median FACT-C score. CONCLUSION The majority of AC patients treated with RCT have acceptable overall QOL scores, which are comparable to those of the normal population. Patients with grade 3 CAE-particularly dyspareunia and fecal incontinence-have a poorer QOL compared to patients without CAE. In order to improve long-term QOL, future strategies might aim at a reduction in dose to the genitalia and more intensive patient support measures.

Abstract
BACKGROUND To implement distress screening in routine radiotherapy practice and to compare computerised and paper-and-pencil screening in terms of acceptability and utility. METHODS We used the Stress Index RadioOncology (SIRO) for screening. In phase 1, 177 patients answered both a computerised and a paper version, and in phase 2, 273 patients filled out either the computerised or the paper assessment. Physicians received immediate feedback of the psycho-oncological results. Patients, nurses/radiographers (n=27) and physicians (n=15) evaluated the screening procedure. RESULTS The agreement between the computerised and the paper assessment was high (intra-class correlation=0.92). Patients' satisfaction did not differ between the two administration modes. Nurses/radiographers rated the computerised assessment less time consuming (3.7 vs 18.5%), although the objective data did not reveal a difference in time demand. Physicians valued the psycho-oncological results as interesting and informative (46.7%). Patients and staff agreed that the distress screening did not lead to an increase in the discussion of psychosocial issues in clinician-patient encounters. CONCLUSION The implementation of a distress screening was feasible and highly accepted, regardless of the administration mode. Communication trainings should be offered in order to increase the discussion of psychosocial topics in clinician-patient encounters.

Abstract
Our aim was to develop a method for species diagnosis and to obtain data on the prevalence of Sarcocystis infections in cattle and water buffalo in the Son La Province of Northern Vietnam. Meat samples of naturally infected animals were examined by light and electron microscopy as well as by molecular methods. A PCR of part of the 18S rDNA gene followed by RFLP analysis was modified to detect infections with different Sarcocystis spp. in cattle and water buffaloes slaughtered in the Son La Province. It showed to be an economical method to detect multiple infections with Sarcocystis spp. Sequence analysis of the PCR amplicons was performed with selected samples and the results were compared with published sequences. With these methods the following Sarcocystis spp. were identified in cattle: Sarcocystis hirsuta, Sarcocystis cruzi and Sarcocystis hominis. Water buffaloes were infected with Sarcocystis fusiformis, S. cruzi, S. hominis and S. hirsuta. The results indicate that Sarcocystis spp. infecting cattle are also able to infect water buffaloes. So the validity of certain Sarcocystis spp. of water buffalo is discussed. Bovine lifestock in Northern Vietnam were commonly infected with Sarcocystis spp.

Abstract
Alveolar echinococcosis, caused by the metacestode Echinococcus multilocularis, is a zoonosis of public health significance. Apart from red foxes, other carnivore species can also serve as definitive hosts of this parasite. This study aimed to determine the occurrence of E. multilocularis in dogs in the Slovak Republic and identify risk factors for acquiring the infection. Out of 289 dogs examined, E. multilocularis was detected in eight samples (2.8%). Positive results were observed in shepherd dogs (12.5%), guard dogs (7.1%), hunting dogs (2.4%) and in one dog with unknown usage (2.5%). Catching rodents and feeding with raw viscera were confirmed to be the most important risk factors for E. multilocularis infection. On the contrary, the way of dog use, frequency of going to the rural areas, the age and gender of animals seem not to be risk factors for infection. No significant association was observed between the positivity of dogs coming from high endemic or non-endemic regions. This is the first report of E. multilocularis in dogs in the Slovak Republic that confirms substantial contribution of dogs to the transmission of the tapeworm in this territory and urges the necessity of prophylactic measures for dog owners.

Abstract
Alveolar echinococcosis, caused by the metacestode of Echinococcus multilocularis, is a zoonosis with a wider distribution area than described in the past. Fox populations living in the Alpine regions of Italy had been considered free from this parasite until 2002, when two infected foxes (Vulpes vulpes) were detected in the Bolzano province (Trentino Alto Adige region) near the Austrian border. The aim of this work was to evaluate the prevalence of infection in red fox populations from five Italian regions. A modified nested PCR analysis was used to detect E. multilocularis DNA in faecal samples. Amplicons were confirmed by sequencing. Of 500 faecal samples from foxes shot in Valle d'Aosta (n=57), Liguria (n=44), Lombardy (n=102), Veneto (n=56), and Trentino Alto Adige (n=241) regions, 24 animals, all from the Trentino Alto Adige region, were found positive. Twenty-two positive animals originated from the Bolzano province and two positive animals from the Trento province. Several localities of the Bolzano province, in which positive foxes were detected, are the same as those where alveolar echinococcosis had been described in humans in the second half of the 19th century, suggesting an old endemicity for the investigated area, which is adjacent to endemic areas of Austria. Therefore, the question arises if we are observing an increase and expansion of foci, or if the new records are due to the more sensitive and specific methods used to detect the worm DNA.

Abstract
Two novel approaches for diagnosis of intestinalEchinococcus multilocularisinfection, the detection ofE. multilocularis-specific coproantigens in ELISA and of copro-DNA by PCR, have been successfully implemented. These methods have proven their value for thepost mortemand theintra vitamdiagnosis ofE. multilocularisin definitive hosts. They have also made novel approaches possible to study the transmission biology of the parasite as they allow detection of the infection in faecal samples collected in the environment. Coproantigen detection is the diagnostic method of choice as it is sensitive, fast and cheap. Studies on faecal samples collected in the field revealed that coproantigen detection did reflect the different prevalences in fox populations as assessed from foxes at necropsy and also the effect of deworming efforts in foxes as achieved by long-term distribution of praziquantel-containing baits. The use of PCR for routine diagnostic or large-scale purposes is hampered by the fact that DNA extraction from faecal material is a very laborious task. Therefore, PCR is rationally used for confirmatory purposes of copro-antigen-positive samples. As taeniid eggs cannot further be differentiated morphologically, PCR is the method of choice to identifyE. multilocularisinfections in faecal or environmental samples containing taeniid eggs. In intermediate rodent hosts, PCR is routinely used in epidemiological studies for identifyingE. multilocularisfrom liver lesions which are often very small, atypical or calcified.

Abstract
A national necropsy survey of red foxes was carried out across Great Britain to record Echinococcus, Trichinella and Toxoplasma. The survey did not record directly, or indirectly using coproantigen/PCR tests, evidence for the presence of Echinococcus multilocularis in 588 animals, although E. granulosus was suspected in six animals. Parasitological evidence for Trichinella spp. could not be found in 587 fox muscle digests, and a specific PCR test also failed to detect Toxoplasma in a sub-set of 61 random fox tongue biopsies. The upper 95% confidence interval for the above parasites was 0.60% (E. multilocularis), 0.60% (Trichinella spp.) and 5.6% (Toxoplasma). The commonest gut parasites were the hookworm Uncinaria stenocephala (41.3%) and the ascarid Toxocara canis (61.6%). This study also reports the second occurrence of Trichuris vulpis in Great Britain.

Abstract
Several cases of hydatid echinococcosis were diagnosed in a laboratory colony of 19 pig-tailed macaques (Macaca nemestrina) at the Paul Ehrlich Institute, Germany. Three hydatid cysts were found in the liver of an euthanized animal. The diagnosis of an Echinococcus granulosus infection was confirmed by histopathology and the results of a specific polymerase chain reaction. The serum of five of 14 other monkeys tested for Echinococcus antibodies using a genus-specific enzyme-linked immunosorbent assay (ELISA) was positive or weakly positive; none of the animals, however, showed specific reactions in a E. multilocularis-specific ELISA. On ultrasonographic examination, alterations in the liver were found in four of the serologically positive monkeys, and two animals showed clinical signs such as progressive anorexia, apathy and icterus. The monkeys had most probably acquired the E. granulosus infection in their breeding colony in Slovenia.

Abstract
BACKGROUND In clinical organ transplantation monoclonal antibodies (mAb) to different surface molecules of immunocompetent cells become integral parts of the immunosuppressive therapy. In this study, a mAb against the rat leukocyte common antigen CD45 (RT7) was tested for its immunosuppressive potency after a single perioperative injection. METHODS Binding and depleting properties of the anti-RT7 mAb were investigated by flow cytometry. In the fully major histocompatibility complex-disparate heart and skin transplantation models (LEW [RT1l]--> LEW.1W [RT1u]), a single dose of anti-RT7 mAb (10 mg/kg) was administered intravenously (day -1). To characterize the long-term acceptance of heart allografts second set skin transplantation (day 100), mixed lymphocyte reaction studies (day 100) and reverse transcriptase-polymerase chain reaction analysis for intragraft cytokine expression (day 200) were performed. RESULTS The anti-RT7 mAb bound to nearly all hematopoietic lineage cells, but particularly T and NK cells, and profoundly depleted these cells in circulation and lymphoid tissues. Anti-RT7 mAb-treated rats showed long-term acceptance of heart allografts (>200 days; n=12), whereas untreated recipients rejected allografts by day 8 (n=6). In contrast to hearts, primary skin allograft survival was only moderately prolonged. Animals with stable heart allograft acceptance showed normal in vitro lymphocyte proliferation responses to donor and third party antigen. These recipients also acutely rejected second set donor-strain skin grafts without inducing rejection of persisting heart allografts. Reverse transcriptase-polymerase chain reaction analysis of intragraft cytokines showed up-regulation of Fas-ligand and IL-4 mRNA in long-surviving heart allografts. CONCLUSIONS The findings demonstrate that a single injection of an anti-RT7 mAb in the rat can induce stable long-term acceptance of heart allografts by transient but profound T-cell depletion. Local immunoregulatory mechanisms seem to play a role for maintenance of long-term graft acceptance.

Abstract
OBJECTIVE Organ allografts contain passenger leukocytes that are transferred to the recipient with the transplantation, but their functional relevance to the recipient's immune system is still controversial. MATERIALS AND METHODS To clarify the functional capacity of passenger leukocytes, we attempted to enhance their effect in rat heart allograft recipients by selective depletion of recipient leukocytes using a monoclonal antibody (mAb) against a recipient-specific allotype of CD45 (RT7(a)). RESULTS Although antibody treatment of the recipient alone led to profound lymphopenia and reversible myelosuppression, additional transplantation of an major histocompatibility complex-incompatible heart graft from an RT7(b) donor led to lethal aplastic anemia in the recipients. This lethal effect was completely abrogated by postoperative anti-CD3 treatment of the recipient and was partially abrogated or delayed by depletion of passenger leukocytes through additional anti-RT7(b) antibody treatment of the recipient or gamma-irradiation of the graft. CONCLUSIONS The results suggest a role for both donor and recipient-type T cells for the induction of aplastic anemia in this model. The study shows that, under defined conditions, allogeneic passenger leukocytes in a heart graft can have a profound effect on the recipient's immune system and bone marrow.

Abstract
With an organ transplant, hematopoietic donor cells are transferred to the recipient. To study the relevance of the resulting microchimerism for allograft acceptance, we analyzed a rat model of cyclosporine-induced tolerance for strongly incompatible heart allografts. Using a monoclonal antibody that detects a donor-specific CD45 allotype (RT7a), we selectively depleted donor leukocytes at different times after transplantation (days 0 or 18). Depletion was similarly effective at both times. However, only depletion on day 0 prevented tolerance induction and was associated with severe acute or chronic graft rejection. This indicates that passenger leukocytes have an essential immunomodulatory effect on the induction phase of allograft acceptance.

Abstract
BALB/c is one of the most widely used and best characterized mouse strains in immunology. For various applications, it is necessary to generate BALB/c transgenic mice. However, using the conventional microinjection technique it is extremely inefficient to produce transgenic BALB/c mice since the one-cell stage BALB/c embryos are highly vulnerable to pronuclear DNA microinjection. To overcome this problem, we have investigated the generation of Egr-1 (early growth response gene) transgenic mice via the transfection of BALB/c embryonic stem cells. Transfectants carrying Egr-1 constructs comprising either the immunoglobulin heavy chain or the MHC class II promoter/enhancer system were injected into C57BL/6 host blastocysts resulting in chimeric mice. For both type of expression vectors, transgenic offspring of the germline chimeras expressed recombinant Egr-1 in lymphoid tissues containing B cells. This demonstrates the successful generation of Egr-1 transgenic BALB/c mice using transfected ES cell.

Abstract
Analyzing the induction kinetics and promoter elements regulating the expression of the transcription factor Egr-1, we found elevated levels of Egr-1-encoding mRNA in synovial fibroblasts of rheumatoid arthritis (RA) patients when compared to controls. By contrast, synovial lymphocytes and macrophages do not show an elevated Egr-1 transcription. Therefore, the overexpression of Egr-1 may serve as a diagnostic marker to characterize synovial fibroblasts of RA patients. To study the regulatory mechanisms controlling Egr-1 expression we analyzed the function of transcription factor binding sites located in the Egr-1 promoter. Individual transcription factor binding sites within the Egr-1 promoter were specifically mutated and Egr-1 promoter activity was tested using reporter gene constructs. Our experiments demonstrate that serum response elements are the main positive regulators and binding to a cAMP responsive element represents the major negative regulator for Egr-1 expression in synovial fibroblasts. In addition, we functionally defined a new element, which was not yet described in the human Egr-1 promoter and which serves as a second negative regulatory element for Egr-1 expression. Therefore increased serum response factor activity or failure of Egr-1 repressing signals may account for Egr-1 overexpression in RA synovial fibroblasts.

Abstract
In mature B lymphocytes, the zinc finger transcription factor early growth response 1 (Egr-1) is one of the many immediate-early genes induced upon B cell antigen receptor engagement. However, its role during earlier stages of lymphopoiesis has remained unclear. By examining bone marrow B cell subsets, we found Egr-1 transcripts in pro/pre-B and immature B lymphocytes, and Egr-1 protein in pro/pre-B-I cells cultivated on stroma cells in the presence of interleukin (IL)-7. In recombinase-activating gene (RAG)-2-deficient mice overexpressing an Egr-1 transgene in the B lymphocyte lineage, pro/pre-B-I cells could differentiate past a developmental block at the B220(low) BP-1(-) stage to the stage of B220(low) BP-1(+) pre-B-I cells, but not further to the B220(low) BP-1(+) CD25(+) stage of pre-B-II cells. Therefore, during early B lymphopoiesis progression from the B220(low) BP-1(-) IL-2R- pro/pre-B-I stage to the B220(low) BP-1(+) IL-2R+ pre-B-II stage seems to occur in at least two distinct steps, and the first step to the stage of B220(low) BP-1(+) pre-B-I cells can be promoted by the overexpression of Egr-1 alone. Wild-type mice expressing an Egr-1 transgene had increased proportions of mature immunoglobulin (Ig)M+ B220(high) and decreased proportions of immature IgM+ B220(low) bone marrow B cells. Since transgenic and control precursor B cells show comparable proliferation patterns, overexpression of Egr-1 seems also to promote entry into the mature B cell stage. Analysis of changes in the expression pattern of potential Egr-1 target genes revealed that Egr-1 enhances the expression of the aminopeptidase BP-1/6C3 in pre-B and immature B cells and upregulates expression of the orphan nuclear receptor nur77 in IgM+ B cells.

Abstract
Recently, extensions of the range of Echinococcus multilocularis in Europe and North America and drastic increases in fox populations in Europe put an increasing proportion of the human population at risk of alveolar echinococcosis. To obtain data on the local infection pressure, studies of the prevalence of the parasite in the animals that transmit the parasite, foxes, dogs, and cats, are urgently required. Such investigations, however, have been hampered by the need for necropsy of the host animal to specifically diagnose infection with the parasite. In this study, a nested PCR and an improved method for DNA extraction were developed to allow the sensitive and specific diagnosis of E. multilocularis infections directly from diluted fecal samples from foxes. The target sequence for amplification is part of the E. multilocularis mitochondrial 12S rRNA gene. The specificity of the method was 100% when it was tested against 18 isolates (metacestodes and adult worms) of 11 cestode species, including E. granulosus. The sensitivity of the method was evaluated by adding egg suspensions and individual eggs to samples of diluted feces from uninfected foxes. The presence of one egg was sufficient to give a specific signal. To confirm the PCR results, an internal probe which hybridized only with E. multilocularis amplification products but not with the DNA of other cestodes was constructed. In order to investigate the applicability of this method for epidemiological studies, 250 wild foxes from a area in southern Germany where echinococcosis is highly endemic were examined by both necropsy and PCR of rectal contents. The sensitivity correlated with the parasites' number and stage of maturity. It ranged from 100% (>1,000 gravid worms) to 70% (<10 nongravid worms). On the basis of positive PCR results for 165 foxes, the sensitivity of the traditional and widely used necropsy method was found to be not higher than 76%. We therefore present this PCR system as an alternative method for the routine diagnosis of E. multilocularis in carnivores.

Abstract
Activation of mature B cells via Ag receptor cross-linking induces transient expression of the transcription factor Egr-1. Although the activating signals leading to Egr-1 induction have been studied extensively, little is known about the genes that are placed further downstream within this activation cascade and that are transcriptionally regulated by Egr-1. To identify such target genes, we established Egr-1-overexpressing transfectants from the murine B cell line K46 and from human Ramos B cells. All clones derived from K46 B cells showed increased expression of CD44. Most interestingly, expression of CD95 (Fas/Apo-1) and of CD23 was down-regulated in all K46 transfectants. As a consequence, they became resistant to apoptosis induced by anti-CD95 Ab treatment. Similarly, the Egr-1-expressing Ramos cells showed reduced levels of CD95 expression. Thus, Egr-1 seems to control the expression of downstream target genes not only as a transcriptional activator, but also as a repressor molecule. In B cells, Egr-1 therefore plays a critical role in integrating the short-lived signal delivered by triggering of the Ag receptor into phenotypic changes, including repression of CD95 and CD23 transcription.

Abstract
In rheumatoid arthritis (RA) synovial fibroblasts are activated by growth factors and cytokines to proliferate and to express matrix-degrading proteases and pro-inflammatory cytokines. This contributes to cartilage degradation and joint destruction. To analyse the parameters that lead to activation of synovial fibroblasts, we established a stable human synoviocyte line (K4IM) from a healthy donor by immortalization with SV40 T antigen (TAg). Characterizing the phenotype of the immortalized K4IM cells, we found that they maintained CD44, CD54 (intercellular adhesion molecule; ICAM-1) and CD95 (Fas) expression, but lost the expression of CD106 (vascular cell adhesion molecule 1; VCAM-1) and the receptors for interleukin 1 (IL-1) and platelet-derived growth factor (PDGF). We also monitored normal expression kinetics of transcription factor Egr-1 upon activation with tumor necrosis factor alpha (TNF-alpha) or synovial fluid from RA patients. In addition, we showed that HLA-DR expression could still be upregulated by recombinant interferon gamma (rINF-gamma). The immortalized K4IM cell line therefore represents a valuable and unique tool to study mechanisms that induce or maintain synoviocyte activation.
