Abstract
Hintergrund Die Multiple Sklerose ist im longitudinalen Verlauf oft ein Krankheitskontinuum mit initial schubförmig-remittierender Phase (RRMS) und späterer sekundärer Progredienz (SPMS). Die meisten bisher zugelassenen Therapien sind bei SPMS nicht ausreichend wirksam. Die frühe Erkennung der SPMS-Konversion ist daher entscheidend für die Therapiewahl. Wichtige Entscheidungshilfen können dabei die Testung kognitiver Teilleistungen und die Magnetresonanztomographie (MRT) sein. Ziel der Arbeit Darstellung der Bedeutung kognitiver Testungen und von MRT-Untersuchungen für Prädiktion und Erfassung der SPMS-Konversion. Ausarbeitung von Strategien der Verlaufsbeobachtung und Therapiesteuerung in der Praxis, insbesondere in der ambulanten Versorgung. Material und Methoden Übersichtsarbeit auf Basis einer unsystematischen Literaturrecherche. Ergebnisse Standardisierte kognitive Testung kann für die frühe SPMS-Diagnose hilfreich sein und die Verlaufsbewertung erleichtern. Eine jährliche Anwendung sensitiver Screeningtests wie Symbol Digit Modalities Test (SDMT) und Brief Visual Memory Test-Revised (BVMT‑R) oder der Brief International Cognitive Assessment for MS (BICAMS)-Testbatterie ist empfehlenswert. Persistierende inflammatorische Aktivität im MRT in den ersten drei Jahren der Erkrankung sowie das Vorhandensein kortikaler Läsionen sind prädiktiv für eine SPMS-Konversion. Ein standardisiertes MRT-Monitoring auf Merkmale einer progressiven MS kann den klinisch und neurokognitiv begründeten SPMS-Verdacht stützen. Diskussion Die interdisziplinäre Versorgung von MS-Patienten durch klinisch versierte Neurologen, unterstützt durch neuropsychologische Testung und MRT, hat einen hohen Stellenwert für die SPMS-Prädiktion und Diagnose. Letztere erlaubt eine frühe Umstellung auf geeignete Therapien, da bei SPMS andere Interventionen als für die RRMS notwendig sind. Nach erfolgter medikamentöser Umstellung erlaubt die klinische, neuropsychologische und bildgebende Vigilanz ein stringentes Monitoring auf neuroinflammatorische und -degenerative Aktivität sowie Therapiekomplikationen.

Abstract
BACKGROUND Recent research has convincingly shown that the ability to work mainly depends on the cognitive status in multiple sclerosis (MS). An international committee of experts recommended a brief neuropsychological battery to evaluate cognitive performance in MS. BICAMS comprises three tests, the Symbol Digit Modalities Test (SDMT), the learning trials of the California Verbal Learning Test II (CVLT-II), and the Brief Visuospatial Memory Test-Revised (BVMT-R). OBJECTIVE To validate BICAMS on a sample of German MS patients and healthy controls (HCs). METHODS According to the international guidelines for validation, examiner's instructions were standardized and translated into German. Due to the availability of better normative data for future applications in routine clinical care and classification of individual performance degree, the Rey Auditory Verbal Learning Test (RAVLT) (German version: Verbaler Lern- und Merkfähigkeits-Test, VLMT) was chosen instead of CVLT-II. 172 MS patients and 100 HCs entered the study. BICAMS was administered at baseline and retest (after 3-4 weeks). RESULTS The groups did not differ in age, gender or education. Mean age of MS patients was 43.33 years (SD 11.64); 68% were female and 86.9% had relapsing-remitting MS. Patients performed significantly worse than HCs on the SDMT (p < 0.01) and on BVMT-R (p < 0.05) but not on VLMT. In addition, BICAMS was shown to be reliable over time: r = 0.71 for BVMT-R, r = 0.72 for VLMT and r = 0.85 for SDMT. SDMT z-score proved to be a good predictor for the ability to work in a full-time (p < 0.001) as well as in a part-time job (p < 0.001). VLMT z-score turned out to be a significant predictor only for the ability to work in a part-time job, while BVMT-R z-score showed no significant predictive value. CONCLUSION In this German validation study with the VLMT, the modified BICAMS (BICAMS-M) turned out to reliably detect cognitive problems in MS patients and to monitor cognitive performance over time. SDMT revealed the best predictive value for working ability. Moreover, only the SDMT was able to predict the ability to work in a part-time or full-time job. Following these results, application of the SDMT is recommended for medical statements on working ability of MS patients.

Abstract
OBJECTIVES Patients with multiple sclerosis (MS) require lifelong therapy. However, success of disease-modifying therapies is dependent on patients' persistence and adherence to treatment schedules. In the setting of a large multicenter observational study, we aimed at assessing multiple parameters for their predictive power with respect to discontinuation of therapy. MATERIALS AND METHODS We analyzed 13 parameters to predict discontinuation of interferon beta-1b treatment during a 2-year follow-up period based on data from 395 patients with MS who were treatment-naïve at study onset. Besides clinical characteristics, patient-related psychosocial outcomes were assessed as well. RESULTS Among patients without clinically relevant fatigue, males showed a higher persistence rate than females (80.3% vs 64.7%). Clinically relevant fatigue scores decreased the persistence rate in men and especially in women (71.4% and 51.2%). Besides gender and fatigue, univariable and multivariable analyses revealed further factors associated with interferon beta-1b therapy discontinuation, namely lower quality of life, depressiveness, and higher relapse rate before therapy initiation, while higher education, living without a partner, and higher age improved persistence. CONCLUSIONS Patients with higher grades of fatigue and depressiveness are at higher risk to prematurely discontinue MS treatment; especially, women suffering from fatigue have an increased discontinuation rate.

Abstract
OBJECTIVE The aim of the present observational study was to determine the effects of a delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) oromucosal spray (Sativex(®) spray), brand name Sativex(®), indicated for drug-resistant MS spasticity, on the driving ability of treated MS patients. METHODS The study was conducted over a period of 4-6 weeks. Thirty-three MS patients with moderate to severe treatment-resistant spasticity and planned to begin add-on treatment with Sativex(®) were enrolled at three specialized MS centres in Germany. A set of five driving test procedures from a validated computerized test battery was used to evaluate the driving ability of eligible patients. Tests were performed by patients at baseline and repeated after 4-6 weeks of treatment with Sativex(®) oromucosal spray. According to German normative data, the test thresholds achieved by the general population served as a reference to allow for a fitness/unfitness to drive classification. RESULTS Patients showed comparable driving test results at baseline and at final visits. Only two patients changed classification shifting from 'unfit' to drive to 'fit' and vice versa. The mean severity of spasticity, as self-reported by the patients, improved with statistical significance. Sativex(®) was generally well tolerated. CONCLUSIONS Treatment of MS patients with Sativex(®) does not negatively impact on driving ability and may improve moderate to severe treatment-resistant MS spasticity.

Abstract
Die photosensibilisierende Wirkung verschiedener cancerogener und nicht cancerogener polycyclischer Kohlenwasserstoffe (3.4-Benzpyren, 9.10-Dimethyl-1.2-benzanthracen, Pyren, Anthracen) auf die Hefezelle wird untersucht.
Es wird gezeigt, daß alle verwendeten Substanzen eine unterschiedliche quantitative photodynamische Wirkung aufweisen.
Die Versuchsergebnisse werden treffertheoretisch ausgewertet. Speziell für das 3.4-Benzpyren resultiert eine völlige Übereinstimmung zwischen der Überlebenskurve und der theoretischen Eintrefferkurve.
Eine Parallelität zwischen cancerogener und photodynamischer Wirksamkeit besteht nicht.

Abstract
The kinetics of the Ce4+-decay and the formation of CO2 are measured in sulfuric acid solutions of malonic acid. The reaction rate is slowed down by Ce3+ -ions due to a reaction of Ce3+ with malonic acid radicals. The primary source of CO2 is the decarboxylation of malonic acid radicals. Implications on the mechanism of the BZ reaction are discussed.

Abstract
The rate of formation of CO2 in the BZ system is measured and compared to the predictions of the Field-Körös-Noyes (FKN)-theory. The experimental rate is found to be larger than the theoretical rate by a factor of about 100. This discrepancy cannot be easily explained without severe changes in the FKN model. Moreover, improved rate constants of the most important organic reactions in the BZ system are given.

Abstract
Adoptive T cell therapies have shown significant promise in the treatment of cancer and viral diseases. One approach, that introduces antigen-specific T cell receptors (TCRs) into ex vivo activated T cells, is designed to overcome central tolerance mechanisms that prevent responses by endogenous T cell repertoires. Studies have suggested that use of higher affinity TCRs against class I MHC antigens could drive the activity of both CD4+ and CD8+ T cells, but the rules that govern the TCR binding optimal for in vivo activity are unknown. Here we describe a high-throughput platform of “reverse biochemistry” whereby a library of TCRs with a wide range of binding properties to the same antigen is introduced into T cells and adoptively transferred into mice with antigen-positive tumors. Extraction of RNA from tumor-infiltrating lymphocytes or lymphoid organs allowed high-throughput sequencing to determine which TCRs were selected in vivo. The results showed that CD8+ T cells expressing the highest affinity TCR variants were deleted in both the tumor infiltrating lymphocyte population and in peripheral lymphoid tissues. In contrast, these same high-affinity TCR variants were preferentially expressed within CD4+ T cells in the tumor, suggesting they played a role in antigen-specific tumor control. The findings thus revealed that the affinity of the transduced TCRs controlled the survival and tumor infiltration of the transferred T cells. Accordingly, the TCR library strategy enables rapid assessment of TCR binding properties that promote peripheral T cell survival and tumor elimination.

Abstract
Intracranial lipomas in an infratentorial and extra-axial location are extremely rare. The presented case of an extensive lipoma of the cerebellopontine angle (CPA) represents 0.05% of all CPA tumors operated on in our department from 1978 to 1996. The lipoma constitutes an important differential diagnosis because the clinical management differs significantly from other CPA lesions. The clinical presentation and management of the presented case are analyzed in comparison to all previously described cases of CPA lipomas. The etiology and the radiological features of CPA lipomas are reviewed and discussed. CPA lipomas are maldevelopmental lesions that may cause slowly progressive symptoms. Neuroradiology enables a reliable preoperative diagnosis. Attempts of complete lipoma resection usually result in severe neurological deficits. Therefore, we recommend a conservative approach in managing these patients. Limited surgery is indicated if the patient has an associated vascular compression syndrome or suffers from disabling vertigo.

Abstract
Abstract
Background
The aim of this randomized clinical trial was to determine whether spinal saddle block (SSB) is superior to total intravenous anaesthesia (TIVA) in perianal surgery.
Methods
Suitable patients aged 18–75 years (American Society of Anesthesiologists grade I or II) scheduled to undergo perianal surgery were randomized to SSB (1·0 ml 0·5 per cent hyperbaric bupivacaine) or TIVA with propofol and fentanyl by means of a laryngeal mask. Cumulative consumption of analgesics within 24 h after surgery was recorded, and postoperative recovery and patient satisfaction were evaluated.
Results
A total of 201 patients were randomized. Supplemental analgesia within 24 h after surgery was required by 31 of 101 patients having SSB and 58 of 100 who had TIVA (P < 0·001). Median monitoring time in the recovery room was 5 (range 1–45) min for SSB versus 44 (4–148) min for TIVA (P < 0·001). Patients in the SSB group were able to eat and drink more quickly, although times to mobilization and micturition were not significantly different. Patients having SSB were more likely to describe the anaesthesia as ‘better than expected’.
Conclusion
SSB is superior to TIVA in patients undergoing perianal surgery in terms of analgesic consumption within 24 h after surgery and aspects of postoperative recovery. Registration number: ISRCTN41981381 (http://www.controlled-trials.com).

Abstract
OBJECTIVE The aim of this study was to investigate the effectiveness and safety of the selective serotonin reuptake inhibitor fluvoxamine (Flevarin) in patients with a chronic pain syndrome due to hip and knee arthritis. METHODS We prospectively investigated 60 patients in a single-centre double-blind study. The group was divided into two groups (M1 fluvoxamine; M2 placebo) each containing 30 patients, age ranging from 30 to 80 years. During treatment results were evaluated using several scales once at the beginning (V1) followed by weekly evaluations (V1-V8) and one final investigation at the end of treatment (V9). The investigated medication consisted of 50-150 mg fluvoxamine. In addition other drugs such as NSAID were administered (diclofenac, piroxicam, ibuprofen). RESULTS Both groups (M1 and M2) showed a reduction of pain during treatment using the visual analogue scale (VAS). However, no statistical difference was found between both groups concerning pain reduction at any time. A significant pain relief was monitored in the patients of the M1 group towards the end of treatment. Concerning the daily impairment because of pain measured by the Griss scale an improvement was seen in 70 % of the patients receiving fluvoxamine versus 44 % in patients receiving placebo. Additionally, an improvement in the M1 group was seen in the WOMAC scale and in factors such as pain, stiffness and mobility compared to the M2 group. Using the CGI scale, 56.6 % of the M1 group compared to 37.9 % of the M2 group were stating that their overall status had improved "much" or "very much" at the end of the treatment (V9). A depression had been excluded in all patients. No statistical differences were seen in the Bf scale (von Zerssen) during all evaluations (V1 to V9). During the whole study 127 side effects were registered in 49 patients. None of the 5 severe events were related to the investigated drug. CONCLUSION Considering the good effects in combination with very few side effects, a positive cost-effectiveness relation for the usage of fluvoxamine can be stated in patients with chronic pain syndrome due to hip and knee arthritis.

Abstract
In this communication we discuss preliminary evidence suggesting a very strong synergism between tumour necrosis factor (TNF) and lipopolysaccharide (LPS) or between TNF and other bacteria in causing haemorrhagic necrosis and lethal shock. We found that TNF by itself does not cause haemorrhagic necrosis when injected into normal skin. TNF also had a rather low systemic toxicity when injected into disease-free, germfree-derived, defined-flora animals. On the other hand the addition of small amounts of LPS markedly raised the lethality of intravenous TNF treatments, and LPS injected into normal skin 'prepared' the site of injection for subsequent induction of haemorrhagic necrosis by locally injected TNF. Similar synergism was observed between TNF and mycoplasma. We suggest that the synergism between TNF and bacterial endotoxin (or other bacteria or bacterial products) may be part of an important defence mechanism against infections which is independent of specific immunity mediated by B and T cells. This synergism may be useful in increasing the therapeutic effects of TNF on tumours if the development of systemic toxicity in this treatment can be prevented.

Abstract
A 40-year-old diabetic woman was diagnosed with rhinocerebral mucormycosis. Cerebral mucormycosis is an acute life-threatening disease, which is caused by fungi of the class Phycomycetae. Clinical suspicion and detection of the fungal hyphae in cerebrospinal fluid (CSF) led to early diagnosis, subsequently confirmed by immunohistochemistry and molecular analysis of fungal RNA. Early infiltration of the infectious agent into the central nervous system resulted in septic thrombosis of the cavernous sinus, mycotic meningoencephalitis, brain infarctions as well as intracerebral and subarachnoidal hemorrhages. Despite immediate high-dose antimycotic treatment, surgical debridement of necrotic tissue, and control of diabetes as a predisposing factor, the woman died 2 weeks after admission. Although fungal organisms are rarely detectable in CSF specimens from patients with mycotic infections of the central nervous system, comprehensive CSF examination is beneficial in the diagnosis of rhinocerebral mucormycosis. Furthermore, a concerted team approach, systemic antifungal agents and early surgical intervention seem to be crucial for preventing rapid disease progression.

Abstract
BACKGROUND McArdle disease, a common metabolic myopathy with autosomal recessive inheritance, is caused by a frequent R50X mutation and many rare mutations in the myophosphorylase gene. OBJECTIVES To identify spectrum and frequencies of myophosphorylase gene mutations in a large cohort of patients with McArdle disease, to discuss diagnostic implications, and to analyse genotype-phenotype relationship. METHODS Molecular genetic analysis of 56 index patients with muscle biopsy-proven myophosphorylase deficiency from Germany (n = 35), UK (n = 13), and several other countries (n = 8) was performed using direct sequencing. RESULTS Allele frequency of the R50X mutation was 58%, and 71% of the patients carried this mutation at least on one allele. We detected 26 other less common mutations, 13 of which are novel: G157V, R161C, Q337R, E384K, S450L, G486D, R570W, K575E, IVS6-2A>T, IVS10+1G>A, R650X, c.1354insC, c.1155_1156delGG. There was no genotype-phenotype correlation with respect to age of onset and severity. R270X was the most frequent mutation among the less common mutations reaching an allele frequency of 5% followed by R94W and G686R representing a frequency of 4% each. CONCLUSIONS The study further extends the genetic heterogeneity of myophosphorylase gene mutations showing no mutational hotspot and no genotype-phenotype correlation. Most novel missense mutations were located in secondary structures or active sites of the enzyme. Some of the less common mutations are recurrent with different frequencies within Europe. Ethnic origin and frequency of less common mutations must be considered to establish efficient strategies in molecular genetic testing. Performing molecular testing can avoid muscle biopsy.

Abstract
We report the results of a longitudinal study involving MRI and clinical follow-up in nine siblings from four families with Miyoshi myopathy (MM). All individuals carried pathogenic dysferlin gene (DYSF) mutations with six of them suffering from symptomatic disease and three being presymptomatic. In presymptomatic subjects, MRI was sensitive to detect alterations in muscle tissue years before disease onset. The first MRI alteration to disclose was evidence for myoedema in dorsal compartment muscles of the legs followed by fatty degeneration. Moreover, MRI changes anticipated the topography of subsequent clinical muscle involvement and progressed from distal to proximal dorsal leg muscles. In symptomatic subjects, MRI changes reflected the pattern and severity of clinical muscle involvement. MRI evidence, however, suggests that muscle involvement is much more prominent in early disease stages than clinically seen. Clinical follow-up up to 8 years made evident that MM onset occurs at a mean age of 18.4 years. The most prominent initial deficit was impaired tiptoe gait due to muscle plantarflexor dysfunction followed by impaired dorsiflexor function. Dorsal compartments were predominantly affected not only in distal but also in proximal leg muscles, and a more rapid progression was noticed during the early phase of the disease. Our data suggest that MRI is a helpful diagnostic tool for an early diagnosis of MM and other distal myopathies since it provides sensitive and topographic information about initial and even preclinical muscle involvement. This is of particular relevance in Miyoshi myopathy because distinct CK elevation is present long before its clinical onset and often misdiagnosed as "idiopathic".

Abstract
Nutrient emissions by point and diffuse sources were estimated for 388 sub-catchments of the Danube river basin for the period 1998-2000 by means of the Model MONERIS. For nitrogen total emissions of 684 kt/a N were estimated for the Danube basin. 80% of these emissions were caused by diffuse sources (mainly groundwater, urban areas and tile drainage). For phosphorus the emission was 57 kt/a P, with a contribution of diffuse sources to this sum of 58%. The comparison of calculated and observed loads shows that the mean deviation for the investigated sub-catchments of the Danube river basin is 20% for dissolved inorganic nitrogen and 34% for phosphorus. The spatial resolution of the emission calculations allows the identification of regional hot spots and the derivation of specific regional measures to reduce the emissions into the Danube and consequently into the Western Black Sea.

Abstract
In the framework of the project daNUbs (Nutrient Management in the Danube Basin and its Impact on the Black Sea) the MONERIS emission model is used for the basin wide calculation of nutrient (nitrogen and phosphorus) emissions in the Danube Basin. The MONERIS model was developed and successfully applied for German river catchments. Based on investigations in selected test regions (case studies) the daNUbs approach is to check the applicability of the MONERIS emission model for the specific conditions of the Danube Basin in more detail than is possible with a basin wide application. Six case studies with areas of 400-3,500 km2 and several subcatchments have been selected in order to represent different conditions along the Danube Basin. In this study region intensive data collection and enhanced monitoring has been performed in order to raise the database significantly above the generally available data. Water balance as well as nutrient balance calculations have been performed with the MONERIS model as well as with other approaches. Results are compared to each other and to data from monitoring. Results up till now showed the applicability and sensitivity of the MONERIS approach in different conditions of the Danube Basin (e.g. emissions via groundwater). They indicated that the nitrogen retention in the catchments is well described with the MONERIS model.

Abstract
Cancers in mouse and man express multiple tumor-specific as well as tumor-associated antigens. Immunodominance in the host response to these antigens can result in successive selection of heritable antigen loss variants. Immunodominance may also prevent the development of responses to new tumor-specific antigens that may arise during tumor progression. Some tumor-specific antigens are retained during tumor progression possibly because they are essential for survival of the malignant phenotype. Immunodominance may allow cancer cells to escape even after loss of a single MHC Class I allele because cross-presentation of the retained antigen by this allele that must be expressed on the surrounding antigen presenting cells sustains the immunodominant response. This prevents effective responses to secondary antigens that may remain as potential targets. Immunization with in vitro selected cancer cell variants that lack the immunodominant antigen can break the immunodominance and prevent escape of cancers from host immunity.

Abstract
OBJECTIVE To compare CSF filtration (CSFF) and plasma exchange (PE) in the treatment of patients with Guillain-Barré syndrome (GBS). METHODS In a prospective controlled clinical trial, 37 patients with acute GBS were randomized to receive either CSFF or PE. Inclusion criteria were fulfillment of National Institute of Neurological and Communicative Disorders and Stroke criteria and disability to walk >5 m unassisted. RESULTS With similar baseline features in both groups (initial disability grades on the six-point grading scale of the GBS Study Group) the primary outcome variable (improvement within 28 days after randomization) was almost identical (test for equivalence p = 0.0014), the mean grade values being 0.82 in the CSFF group and 0.80 in the PE group. After 56 days, 56% (9 of 16 patients) of the CSFF group and 37% (7 of 19 patients) of the PE group had reached grade 2 (i.e., ability of unassisted walking >5 m). After 6 months, the probability to reach grade 2 was about 80% in both groups. In the CSFF group, transient pleocytosis occurred without apparent clinical complications. Clinically relevant complications were higher in the PE-treated group. CONCLUSIONS Although the number of patients was small, the authors found that the treatment of GBS with CSFF is at least as effective as with PE. CSFF might work by removing from the CSF inflammatory mediators, autoantibodies, or other factors.

Abstract
Vaccination with a peptide representing a CTL epitope from the human papillomavirus (HPV)16 E7 protein induces a specific CTL response that prevents the outgrowth of HPV16 E7-expressing tumors. In contrast, vaccination with a peptide encoding an adenovirus type 5 (Ad5) E1A CTL epitope results in CTL tolerance and enhanced growth of an Ad5 E1A-expressing tumor. It is unclear why these peptides induce such opposite effects. To determine whether a difference in pharmacokinetics can explain the functional contrasts, tritiated Ad5 E1A and HPV16 E7 peptides were injected into mice. Results show that the tolerizing peptide spread through the body 16 times faster than the activating peptide and was cleared at least 2 times faster. The HPV16 E7 peptide kinetics correlated with the kinetics of HPV16 E7-specific CTL induction. In contrast, Ad5 E1A peptide injection resulted in physical deletion of preexisting Ad5 E1A-specific CTLs within 24 h after injection. This tolerization occurred at the time when the peptide reached its maximum peptide concentration in the organs. These data suggest that ubiquitous expression of the tolerizing Ad5 E1A peptide within a short period of time causes activation-induced cell death of Ad5 E1A-specific CTLs. Therefore, information on the pharmacokinetics of peptides is vital for the safety and efficacy of peptide-based vaccines.

Abstract
In the months and years after first diagnosis, cancers often show an increase in their malignancy such as faster growth, resistance to chemo- and/or hormonal therapy, and loss of antigens targeted by immunotherapy. Our objective was to develop a model in which one can track the changes occurring as a result of in vivo immune selection, such as the loss of antigen, the emergence of previously hidden antigens, or the acquisition of new tumor-specific antigens. In this study, we used the primary UV-induced murine tumor 8101, which consists predominantly of regressor tumor cells that express the immunodominant mutant p68 antigen, but this tumor also contains progressor variants that have lost this antigen. To search for tumor-specific antigens on the immune escape progressors, we raised CD8+ T cells specific for these variants. We found that one of the escape variants expressed a previously unrecognized, unique tumor-specific antigen. However, this unique antigen was not readily detectable on any of the other 8101 lines we tested. To prove that these antigenically distinct cancer variants had indeed been derived from the same tumor and neither represented new tumors nor contaminations by other cell lines, we used unique tumor-specific p53 mutations as a lineage-specific marker to demonstrate that these antigenically distinct progressor variants were derived from the 8101 tumor. Because p53 mutations occur very early during UV carcinogenesis and vary from tumor to tumor, they provide convenient reliable markers for tracking the origin of cancers arising after immune selection or immunotherapy.

Abstract
One of the major obstacles in tumor-immunology is the outgrowth of malignant tumors despite their immunogenicity and recognition by the immune-system. Multiple mechanisms for this phenomenon have been proposed. We review the possible involvement of transforming growth factor beta (TGF-beta) in this context. TGF-beta is a cytokine with pleiotropic functions, involved in multiple physiologic processes including immunoregulation. Immune elimination of most cancers ultimately depends on cytolytic T cells (CTL). We propose a mechanism of specific suppression of cytolytic T cell (CTL)-responses mediated through immunoglobulin-bound TGF-beta (IgG-TGF-beta), secreted by activated B cells, and a cell of myeloid origin. This mononuclear "Veto" cell presumably binds IgG-TGF-beta through Fc-receptors and activates latent TGF-beta. The suggestion that B cell responses can inhibit tumor rejection is supported by observations in B cell-deficient mice. Ways for enhancing effective cancer immunity by interfering with the network of interactions involving IgG-TGF-beta are discussed.

Abstract
We present the first observation of self-amplified spontaneous emission (SASE) in a free-electron laser (FEL) in the vacuum ultraviolet regime at 109 nm wavelength (11 eV). The observed free-electron laser gain (approximately 3000) and the radiation characteristics, such as dependency on bunch charge, angular distribution, spectral width, and intensity fluctuations, are all consistent with the present models for SASE FELs.

Abstract
While it has been known for decades that the growth of tumor transplants can be enhanced immunologically, the potential significance of these previous findings to the development of primary tumors and the mechanisms of tumor enhancement has remained obscure. This review will summarize recent experiments indicating that primary tumor development can be enhanced by active immunization. The evidence suggests that antibodies, B cells and CD4+ T cells can play a critical role in enhancing the development of primary, tumors, whereas endogenous interferon-gamma (IFNgamma) can counteract enhancement. Thus, we envision two possible functions of IFNgamma: (i) preventing B cell and antibody enhancement and (ii) counteracting tumor promotion independent of T and B cells.

Abstract
Growth Regulated Oncogene-alpha (GRO-alpha) is an autocrine growth factor in melanoma and is a member of the C-X-C family of chemokines which promote chemotaxis of granulocytes and endothelia through binding to CXC Receptor 2. We found previously that variants of murine squamous cell carcinoma PAM 212 which grow and metastasize more rapidly in vivo constitutively express increased levels of murine GRO-alpha, designated mGRO-alpha, or KC. We have examined the possible role of mGRO-alpha expression in malignant progression of squamous cell carcinoma PAM 212 in homologous BALB/c and BALB CXC Receptor-2 deficient mice. Transfection of the PAM 212 cell line which exhibits low expression of GRO-alpha and malignant potential with a pActin-KC vector encoding mGRO-alpha enabled isolation of PAM-KC expressing cell lines. These PAM-KC transfectants displayed an increased rate of growth and metastasis in BALB/c mice, similar to the highly malignant phenotype observed in spontaneously occurring metastatic variants. Furthermore, the PAM-KC tumors showed an increase in infiltration of host leukocytes and CD31+ blood vessels, consistent with increased CXC chemokine activity. The increased growth of PAM-KC cells was attenuated in CXCR-2 deficient mice, indicating that the increased growth was dependent in part upon host cells responsive to the CXC chemokine. Together, these results show that a CXC chemokine such as GRO-alpha can promote malignant growth of murine squamous cell carcinoma by a host CXCR-2 dependent pathway. Oncogene (2000) 19, 3477 - 3486

Abstract
We present a case of an adult male patient showing clinical, neurophysiological and histological signs consistent with the phenotype of facioscapulohumeral muscular dystrophy. On molecular testing with a 4q35-DNA-probe p13E-11 (D4F104S1), the patient, his clinically unaffected mother and two sisters shared a 4q35-EcoRI-DNA-fragment of 35 kb on the transition between FSHD1A-associated and polymorphic fragments. Explanatory hypotheses, such as reduced penetrance in females or a phenotype unlinked to the 4q35-locus are considered. Alternatively, additional changes in the unidentified FSHD1A gene could have caused the phenotype. Thus, in such rare cases, the diagnostic evidence of 4q35-EcoRI-fragments is still limited.
