Abstract
We present the first comprehensive tests of the universality of the light leptons in the angular distributions of semileptonic B^{0}-meson decays to charged spin-1 charmed mesons. We measure five angular-asymmetry observables as functions of the decay recoil that are sensitive to lepton-universality-violating contributions. We use events where one neutral B is fully reconstructed in ϒ(4S)→BB[over ¯] decays in data corresponding to 189 fb^{-1} integrated luminosity from electron-positron collisions collected with the Belle II detector. We find no significant deviation from the standard model expectations.

Abstract
We present a study on the optical losses of Fabry-Pérot cavities subject to realistic transverse mirror misalignment. We consider mirrors of the two most prevalent surface forms: idealised spherical depressions, and Gaussian profiles generated by laser ablation. We first describe the mode mixing phenomena seen in the spherical mirror case and compare to the frequently-used clipping model, observing close agreement in the predicted diffraction loss, but with the addition of protective mode mixing at transverse degeneracies. We then discuss the Gaussian mirror case, detailing how the varying surface curvature across the mirror leads to complex variations in round trip loss and mode profile. In light of the severe mode distortion and strongly elevated loss predicted for many cavity lengths and transverse alignments when using Gaussian mirrors, we suggest that the consequences of mirror surface profile are carefully considered when designing cavity experiments.

Abstract
BACKGROUND Approvals of cancer therapeutics are primarily disease entity specific. Current molecular diagnostic approaches frequently identify actionable alterations in rare cancers or rare subtypes of common cancers for which the corresponding treatments are not approved and unavailable within clinical trials due to entity-related eligibility criteria. Access may be negotiated with health insurances. However, approval rates vary, and critical information required for a scientific evaluation of treatment-associated risks and benefits is not systematically collected. Thus clinical trials with optimized patient selection and comprehensive molecular characterization are essential for translating experimental treatments into standard care. PATIENTS AND METHODS Continuous ReAssessment with Flexible ExTension in Rare Malignancies (CRAFT) is an open-label phase II trial for adults with pretreated, locally advanced, or metastatic solid tumors. Based on the evaluation by a molecular tumor board, patients are assigned to combinations of six molecularly targeted agents and a programmed death-ligand 1 (PD-L1) antagonist within seven study arms focusing on (i) BRAF V600 mutations; (ii) ERBB2 amplification and/or overexpression, activating ERBB2 mutations; (iii) ALK rearrangements, activating ALK mutations; (iv and v) activating PIK3CA and AKT mutations, other aberrations predicting increased PI3K-AKT pathway activity; (vi) aberrations predicting increased RAF-MEK-ERK pathway activity; (vii) high tumor mutational burden and other alterations predicting sensitivity to PD-L1 inhibition. The primary endpoint is the disease control rate (DCR) at week 16; secondary and exploratory endpoints include the progression-free survival ratio, overall survival, and patient-reported outcomes. Using Simon's optimal two-stage design, 14 patients are accrued for each study arm. If three or fewer patients achieve disease control, the study arm is stopped. Otherwise, 11 additional patients are accrued. If the DCR exceeds 7 of 25 patients, the null hypothesis is rejected for the respective study arm. CONCLUSIONS CRAFT was activated in October 2021 and will recruit at 10 centers in Germany. TRIAL REGISTRATION NUMBERS EudraCT: 2019-003192-18; ClinicalTrials.gov: NCT04551521.

BACKGROUND Eccrine porocarcinoma (EPC) is a rare skin cancer arising from the eccrine sweat glands. Due to the lack of effective therapies, metastasis is associated with a high mortality rate. OBJECTIVES To investigate the drivers of EPC progression. METHODS We carried out genomic and transcriptomic profiling of metastatic EPC (mEPC), validation of the observed alterations in an EPC patient-derived cell line, confirmation of relevant observations in a large patient cohort of 30 tumour tissues, and successful treatment of a patient with mEPC under the identified treatment regimens. RESULTS mEPC was characterized by a high tumour mutational burden (TMB) with an ultraviolet signature, widespread copy number alterations and gene expression changes that affected cancer-relevant cellular processes such as cell cycle regulation and proliferation, including a pathogenic TP53 (tumour protein 53) mutation, a copy number deletion in the CDKN2A (cyclin dependent kinase inhibitor 2A) region and a CTNND1/PAK1 [catenin delta 1/p21 (RAC1) activated kinase 1] gene fusion. The overexpression of EGFR (epidermal growth factor receptor), PAK1 and MAP2K1 (mitogen-activated protein kinase kinase 1; also known as MEK1) genes translated into strong protein expression and respective pathway activation in the tumour tissue. Furthermore, a patient-derived cell line was sensitive to EGFR and MEK inhibition, confirming the functional relevance of the pathway activation. Immunohistochemistry analyses in a large patient cohort showed the relevance of the observed changes to the pathogenesis of EPC. Our results indicate that mEPC should respond to immune or kinase inhibitor therapy. Indeed, the advanced disease of our index patient was controlled by EGFR-directed therapy and immune checkpoint inhibition for more than 2 years. CONCLUSIONS Molecular profiling demonstrated high TMB and EGFR/MAPK pathway activation to be novel therapeutic targets in mEPC.

Abstract
Background:The ATTRA registry captures more than 95% of patients with RA, AxSpA, or PSA treated with biologics in the Czech Republic (CZ). In CZ, anti-TNF therapy is reimbursed for RA if DAS28>5.1 despite therapy with csDMARDs, for PSA if disease is not “adequately controlled” with csDMARDs and for AS if BASDAI>4 and CRP/ESR elevated above normal.Objectives:We aimed to investigate gender-related differences in baseline characteristics and treatment effectiveness among patients with RA, AxSpa, and PsA starting first targeted therapy (TT) in CZ.Methods:In this observational cohort study, the ATTRA register provided prospectively collected data on RA, AxSpA and PsA patients who initiated their first TT (mostly by TNFi) in 2012–6/2018. Treatment effectiveness and adherence was assessed at 12 months by a change in patient-reported outcomes (PROs), CRP and % drug survival. Differences in categorical and continuous data btw males and females were assessed using the Pearson X2test (of Fisher exact test, as appropriate), or Mann-Whitney test resp. This study was largely descriptive, and no statistical adjustments have been made.Results:A total of 1602 RA, 1306 AxSpa, and 493 PsA patients were included. The difference in baseline characteristics btw women and men starting TT are shown in table 1. Their response and adherence to TT after one year is shown in table 2.Conclusion:When starting their first TT, males tended to have higher levels of CRP, while females were more often (ex)smokers and reported worse parameters of quality of life across the diagnostic groups. The improvement of PROs was similar in males and females, while males with axSpA and PsA showed larger improvements in CRP. Survival on drug at one year was similar, save for AxSpA, where males showed better survival.References:Acknowledgments:Supported by project 00023728 of Ministry of Health, CZDisclosure of Interests:Jakub Zavada Speakers bureau: Abbvie, UCB, Sanofi, Elli-Lilly, Novartis, Zentiva, Accord, Lucie Nekvindova: None declared, Karel Pavelka Consultant of: Abbvie, MSD, BMS, Egis, Roche, UCB, Medac, Pfizer, Biogen, Speakers bureau: Abbvie, MSD, BMS, Egis, Roche, UCB, Medac, Pfizer, Biogen, Pavel Horak Speakers bureau: Pfizer, Abbvie, Eli lilly.

Abstract
Background:Cardiovascular disease (CVD) is one of the most common causes of death in Rheumatoid arthritis patients. Increased arterial stiffness is considered as an independent risk factor of development CVD and a predictor of all-cause morbidity and mortality. Increased arterial stiffness, due to premature vascular ageing, can be observed in patients with chronic inflammatory diseases as well as in RA patients.Objectives:To evaluate arterial stiffness determined as carotid – femoral pulse wave velocity in rheumatoid arthritis patients. The comparison of traditional and nontraditional risk factor of CVD, disease activity and laboratory findings connected with subclinical atherosclerotic changes.Methods:We evaluated data of 50 patients with rheumatoid arthritis (39 females, 11male, mean age 57, mean duration of disease of 13years). The arterial stiffness, measured as carotid – femoral pulse wave velocity (PWV), was established with the SphygmoCor system. This non-invasive technique uses the principle of applanation tonometry. Our control group counted 25 heathy male and females with no history of CVD or autoimmune disease. We evaluated the influence of traditional risk factors for CVD as age, smoking, BMI, lipid profile, diabetes mellitus, history of CV and cerebrovascular morbidity to PWV in RA patients. Non-traditional risk factors contained Adiponectin, Fetuin A, Endothelin-1 and Asymmetric dimethylarginine. To measure disease activity was used DAS 28 and inflammatory parameters as a marker of current disease activity. For chronic changes was used X-ray of small joints. Results were correlated with PWV and statistically evaluated.Results:Mean PWV in Rheumatoid arthritis patients was significantly higher (9.7 m/s) than that in healthy control group (6.7m/s). 49% of RA patients (n= 24) had increased arterial stiffness according to their age. 32% patients (n=16) with PWV over 10m/s that indicates aortal function alteration. We didn´t find correlation between arterial stiffness and traditional and non-traditional CVD risk factors. Increased PWV was not associated with high disease activity. Patients with higher arterial stiffness according to their age had longer RA history, higher level of rheumatoid factor, were more frequently anti-citrullinated protein antibodies (ACPA) negative and were more frequently treated with biological therapy.Conclusion:Rheumatoid arthritis patients are in increased risk of CV disease. PWV is considered as an independent risk factor of CVD. We proved increased arterial stiffness and vascular ageing in comparison to healthy controls. We did not find correlation between increased arterial stiffness and disease activity. All CVD risk factor intervention is necessary to improve the prognosis of patients. Further investigation is needed to establish the role of increased PWV in RA patients.References:[1]Reference Values for Arterial Stiffness’ Collaboration.

Abstract
CLINICAL ISSUE Innovative next generation sequencing (NGS) technologies and comprehensive sequencing investigations in large patient cohorts have paved the way for very promising personalized treatment strategies based on the molecular characteristics of individual tumors. STANDARD TREATMENT Targeted therapies, such as tyrosine kinase inhibitors, antibodies and modern immunotherapeutic approaches are well established as monotherapy and combination therapy for many hematological and oncological malignancies. TREATMENT INNOVATIONS A plethora of innovative therapies targeting various components of intracellular signaling cascades and effective mechanisms against oncogenes as well as the availability of NGS technologies enable personalized cancer treatment based on the molecular profiles of individual tumors and genetic stratification, within clinical trials. DIAGNOSTIC WORK-UP Comprehensive genetic approaches including cancer gene panel sequencing, whole exome, whole genome and transcriptome sequencing are carried out to a varying extent and particularly in the academic setting. PERFORMANCE Principally, a comprehensive characterization of tumors in addition to DNA and RNA sequencing that also incorporates epigenetic, metabolomic, and proteomic alterations would be desirable. A comprehensive clinical implementation of integrative, multidimensional genetic typing is, however, currently not possible. ACHIEVEMENTS It remains to be demonstrated whether these approaches will translate into significantly better outcomes for patients and whether they can be increasingly implemented in the routine diagnostic work-up. PRACTICAL RECOMMENDATIONS The selection of diagnostic tools in individual cases and the extent of genomic analyses in the clinical context, need to take the availability of methods as well as the present clinical situation into account.

Abstract
We demonstrate efficient four-wave mixing among different spatial modes in a 1-km long two-mode fiber at telecommunication wavelengths. Two pumps excite the LP01 and LP11 modes, respectively, while the probe signal excites the LP01 mode, and the phase conjugation (PC) and Bragg scattering (BS) idlers are generated in the LP11 mode. For these processes we experimentally characterize their phase matching efficiency and bandwidth and find that they depend critically on the wavelength separation of the two pumps, in good agreement with the numerical study we carried out. We also confirm experimentally that BS has a larger bandwidth than PC for the optimum choice of the pump wavelength separation.

Abstract
The interpretation of planar retarding potential analyzers (RPA) during ionospheric sounding rocket missions requires modeling the thick 3D plasma sheath. This paper overviews the theory of RPAs with an emphasis placed on the impact of the sheath on current-voltage (I-V) curves. It then describes the Petite Ion Probe (PIP) which has been designed to function in this difficult regime. The data analysis procedure for this instrument is discussed in detail. Data analysis begins by modeling the sheath with the Spacecraft Plasma Interaction System (SPIS), a particle-in-cell code. Test particles are traced through the sheath and detector to determine the detector's response. A training set is constructed from these simulated curves for a support vector regression analysis which relates the properties of the I-V curve to the properties of the plasma. The first in situ use of the PIPs occurred during the MICA sounding rocket mission which launched from Poker Flat, Alaska in February of 2012. These data are presented as a case study, providing valuable cross-instrument comparisons. A heritage top-hat thermal ion electrostatic analyzer, called the HT, and a multi-needle Langmuir probe have been used to validate both the PIPs and the data analysis method. Compared to the HT, the PIP ion temperature measurements agree with a root-mean-square error of 0.023 eV. These two instruments agree on the parallel-to-B plasma flow velocity with a root-mean-square error of 130 m/s. The PIP with its field of view aligned perpendicular-to-B provided a density measurement with an 11% error compared to the multi-needle Langmuir Probe. Higher error in the other PIP's density measurement is likely due to simplifications in the SPIS model geometry.

Abstract
We report the fabrication of a tellurite optical fiber with a suspended core design, formed on a 220-nm-wide filament of glass. The fiber was pumped at two different wavelengths (1500 and 2400 nm) using femtosecond pulses generated from an optical parametric oscillator (OPO) in order to produce mid-infrared supercontinuum (SC). We observed that SC spectra extending to 3 μm were readily generated. To further optimize the design, detailed numerical study was performed, which revealed how the fiber structural characteristics dramatically influence the spectral broadening because of the changes in the dispersion profile and in turn, the interplay of nonlinear effects that give rise to SC generation. We found that an accurate control of the core shape can be employed to contain the generated SC spectra within well-defined spectral regions or to provide a broad extension of the continuum to beyond 4 μm.

Abstract
We experimentally study the spectral broadening of intense, ∼ 100 femtosecond laser pulses at 785 nm coupled into different kinds of hollow core capillary fibers, all filled with air at ambient pressure. Differently from observations in other gases, the spectra are broadened with a strong red-shift due to highly efficient intrapulse Raman scattering. Numerical simulations show that such spectra can be explained only by increasing the Raman fraction of the third order nonlinearity close to 100%. Experimentally, these broadened and red-shifted pulses do not generally allow for straightforward compression using, for example, standard chirped mirrors. However, using special hollow fibers that are internally coated with silver and polymer we obtain pulse durations in the sub-20 fs regime with energies up to 300 μJ.

Abstract
Titanium (Ti)-in-diffused lithium niobate waveguide mode filters fabricated using laser-induced forward transfer followed by thermal diffusion are presented. The mode control was achieved by adjusting the separation between adjacent Ti segments thus varying the average value of the refractive index along the length of the in-diffused channel waveguides. The fabrication details, loss measurements and near-field optical characterization of the mode filters are presented. Modeling results regarding the device performance are also discussed.

Abstract
Evanescent coupling of light from glass channel waveguides into the whispering gallery modes of glass microspheres of radius 15?m and 100?m is studied experimentally at wavelengths near 1550 nm. Fitting the positions, widths and heights of resonances in the experimental spectra to the characteristic equation for microsphere modes and to universal coupled microresonator theory, we establish sphere radius and index, identify mode numbers, and determine losses. The results provide detailed information for the design of optical devices incorporating microsphere resonators in planar lightwave circuits.

Abstract
We hypothesized that nucleic acids, free and/or complexed, filtered and/or locally released, might be entrapped in the kidneys because of the specific nucleic acid binding microbial pattern recognizing Toll-like receptors (TLRs). This hypothesis of nucleic acid binding potential was tested using paraffin sections from healthy control, SLE and transplant kidneys, which were labelled using TLR-specific rabbit or goat anti–human antibodies in immunoperoxidase staining. Normal and transplant kidneys contain some double- (TLR-3) and single-stranded RNA binding (TLR-8) receptors, but in particular double-stranded RNA binding receptor TLR-7, mostly in tubuli, whereas no DNA binding TLR-9 was found. SLE kidneys contain more TLR-3 and TLR-8 and express de novo also TLR-9, in particular in glomeruli. On the contrary, TLR-7 was relatively weak in SLE. It is concluded that kidneys have a capacity to bind nucleic acids. TLR stimulation leads to the production of tumour necrosis factor-α and other pro-inflammatory cytokines and to up-regulation of co-stimulatory molecules necessary for the adaptive immune response. This makes renal tissues a potential target for inflammatory and immune responses in autoimmune disease and in the reaction for the foreign tissue.

Abstract
Multimode nonlinear pulse propagation within a Ta(2)O(5) rectangular rib waveguide has been numerically simulated. The study provides information relating to both the localized spectral evolution along the waveguide and the transverse spectral variation across the guide. The results explain measurements from our previous near-field scanning microscopy experiments that were designed to map continuum generation along and across such waveguides, and that deviated significantly from simple theory. The simulations predict an increased nonlinear phase modulation compared to that occurring in nonlinear single-mode waveguides, due to intermodal nonlinear effects such as cross-phase modulation, leading to an enhanced spectral broadening.

Abstract
We report the generation of white light from a picosecond pump by efficient four-wave mixing processes. A 530 nm green source based on a frequency-doubled Yb-doped fiber laser generates strong red and blue sidebands in the secondary cores of a holey fiber with large air-filling factor. Phase matching is attributed to birefringence within the submicrometer-sized secondary cores induced by non-symmetric deformation during the fiber drawing.

Abstract
HER2/neu overexpression is a driving force in the carcinogenesis of several human cancers. In breast cancer the prognostic influence of HER2/neu was shown to be at least partly based on increased metastatic potential mediated by the chemokine–chemokine receptor pair SDF-1(CXCL12)/CXCR4. We wanted to evaluate the influence of HER2/neu on ovarian cancer prognosis and to investigate whether compromised survival would correlate with CXCR4 expression and/or SDF-1 abundance. Therefore, we analysed HER2/neu, CXCR4, and SDF-1 in 148 ovarian tumour samples by means of immunohistochemistry on tissue microarrays. Overexpression of HER2/neu was found in 27.6% of ovarian cancer tissues and in 15% of ovarian borderline tumours. In ovarian cancer patients, overexpression of HER2/neu correlated closely with overall survival (univariate hazard ratio (HR) 2.59, P=0.005; multiple corrected HR 1.92, P=0.074). In contrast, CXCR4 expression and SDF-1 abundance had no impact on overall survival, and both parameters were not correlated with HER2/neu expression. As expected, cytoplasmic CXCR4 expression and SDF-1 abundance correlated closely (P<0.0001). Our results confirm a univariate influence of HER2/neu expression on overall survival, which was completely independent of the expression of CXCR4 and the abundance of SDF-1, implying significant differences between the HER2/neu downstream pathways in ovarian cancer compared with breast cancer.

Abstract
18583 Background: Anemia is a common complication in patients who receive anticancer therapy. We evaluated the efficacy of darbepoetin alfa in early vs. late treatment in patients with genitourinary tumors undergoing chemotherapy. We wanted to investigate whether an early onset of treatment with darbepoetin alfa reduces frequency of red blood cell transfusion and increases patients’ QoL. Methods: Patients on chemotherapeutic treatment for a urogenital neoplasia and a hemoglobin between 10–12 g/dl were randomized between an immediate start of treatment with darbepoetin alfa 150 μg sc weekly (group A) and a Hb below 10 g/dl or clinical symptoms (group B). Results: 52 patients out of 68 (76.5%) completed the trial, 7/40 patients (17%) in group A and 9/28 patients (32%) in group B withdraw from the study. An intent to treat analysis was performed and showed a significant superiority (p = 0.023, log-rank test) for the early treatment. In group A, only 12.5% of patients (5/40) received at least one red blood cell transfusion compared to group B, where 39% of the patients (11/28) received a transfusion. In group A the mean Hb level increased steadily, starting with a baseline value of 11.0 g/dl. In week 21 a mean Hb level of 12.8 g/dl was reached, resulting in an overall increase in Hb of 1.8 g/dl. In group B, which had a comparable baseline Hb level of 10.9 g/dl, the mean Hb value decreased initially during the first 4 weeks to 10.0 g/dl. In week 21 a level of 11.4 g/dl was reached, resulting in a total Hb-increase of 0.5 g/dl. When anemia treatment was initiated early, the mean Hb level always remained in the range of 11 to 13 g/dl from the beginning of the study, in the B group the mean level of 11 g/dl was first achieved after 12 weeks. 35% in group A compared to 54% in group B (p = 0.13) experienced a dose doubling. The mean values (EORTC-QLQ-C30) of all symptom scales in group A were markedly below those in group B with the highest difference for dyspnea, 29.1 points (p < 0.001). Conclusions: Early treatment with darbepoetin alfa in patients with urogenital cancer results in optimal hemoglobin levels according to EORTC guidelines and consequently in a reduction of red blood cells transfusion. Furthermore, in patients with earlier initiation of treatment a clinically significant improvement of dyspnea can be observed. [Table: see text]

Abstract
Five human soft tissue sarcoma (STS) cell lines (HTB-82 rhabdomyosarcoma, HTB-91 fibrosarcoma, HTB-92 liposarcoma, HTB-93 synovial sarcoma and HTB-94 chondrosarcoma) were analysed for their sensitivity to tumour necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) and the function of the TRAIL apoptotic pathway in these cells. TRAIL induced significant apoptosis (>90%) in HTB-92 and HTB-93 cells, whereas no effect was observed in HTB-82, HTB-91 and HTB-94 cells. TRAIL-Receptor 1 (TRAIL-R1) was expressed in TRAIL-sensitive HTB-92 and HTB-93 cell lines, but not in TRAIL-resistant HTB-91 and HTB-94 cells. HTB-82 cells, which expressed the long (c-FLIP(L)) and short (c-FLIP(S)) splice variants of the FLICE-like inhibitory protein (FLIP), were resistant to TRAIL in spite of the presence of TRAIL-R1. TRAIL-R2,-R3,-R4 and osteoprotegerin (OPG) expression did not correlate with TRAIL sensitivity. Coincubation of TRAIL and doxorubicin led to the overexpression of TRAIL-R2 resulting in a synergistic effect of doxorubicin and TRAIL in TRAIL-sensitive cell lines and in the overcoming of TRAIL-resistance in all of the TRAIL-resistant cell lines, except HTB-91, which lacked caspase 8 expression. These data suggest that TRAIL, either as a single agent or in combination with cytotoxic agents, might represent a new treatment option for advanced STS, which constitutes a largely chemotherapy-resistant disease.

Abstract
Schistosomes are digenean flukes, parasitic of birds, mammals and crocodiles. The family Schistosomatidae contains species of considerable medical and veterinary importance, which cause the disease schistosomiasis. Previous studies, both morphological and molecular, which have provided a good deal of information on the phylogenetics of this group, have been limited in the number of species investigated or the type or extent of molecular data used. This paper presents the most comprehensive phylogeny to date, based on the sequences of 3 genes, complete ribosomal small subunit rRNA and large ribosomal subunit rRNA, and mitochondrial cytochrome oxidase 1, sequenced from 30 taxa including at least 1 representative from 10 of the 13 known genera of the Schistosomatidae and 17 of the 20 recognized Schistosoma species. The phylogeny is examined using morphological characters, intermediate and definitive host associations and biogeography. Theories as to the origins and spread of Schistosoma are also explored. The principal findings are that Ornithobilharzia and Austrobilharzia form a sister group to the Schistosoma; mammalian schistosomes appear paraphyletic and 2 Trichobilharzia species, T. ocellata and T. szidati, seem to be synonymous. The position of Orientobilharzia within the Schistosoma is confirmed, as is an Asian origin for the Schistosoma, followed by subsequent dispersal through India and Africa.

Abstract
The aim of this study was a contemporaneous measurement and a mutual comparison of plasma cells proliferative activity and grade of apoptosis in patients with monoclonal gammopathy of undetermined significance (MGUS) and various phases of MM i.e. smoldering (SMM), stable/plateau and active (progression/relapse) forms of this disease. The analyzed group of 197 patients consisted of 30 MGUS, 21 SMM, 82 patients examined at the time of MM diagnosis and 64 patients analyzed during various phases of the disease after previous chemotherapy. Plasma cell proliferative activity was measured by means of a propidium iodide index (PC-PI) examined by flow cytometry using a DNA/CD138 double staining technique. For detection of plasma cells entering apoptosis (PC-AI) flow cytometry method with annexin V FITC and MoAb CD138 was used. The individuals with MGUS, SMM and stable/plateau form of MM had overall low levels of PC-PI (M-1.8, 1.7% and 2.1%) and relatively high levels of PC-AI (M-9.1, 10.8 and 9.0%). The correlation between PC-PI and PC-AI was in all the groups mutually highly statistically significant (p=0.000). Analysis of plasma cells proliferative activity (PC-PI) was statistically significant in comparison of MGUS or SMM and versus: patients examined at the time of MM diagnosis (p=0.018 or 0.016); patients evaluated during various phases of MM after previous chemotherapy (p=0.021 or 0.019); stable/plateau MM phase in the cohort of all patients (p=0.017 or 0.040); in the plateau phase after chemotherapy (p=0.008 or 0.024) but insignificant in comparison of MGUS and SMM and with the stable group examined at the time of MM diagnosis. Analysis of the apoptotic process revealed significant differences when comparing PC-AI of SMM but not MGUS group versus all cohort of stable/plateau MM patients (p=0.045); there were also insignificant differences in comparison of MGUS and SMM groupsand versus the stable form of MM measured at the time of MM diagnosis or plateau phase after chemotherapy. There was observed a statistically significant difference in the PC-AI in comparison of SMM group versus group of all patients examined at the time of MM diagnosis (p=0.001) or in various phases of this disease (p=0.015) and the group of MGUS patients compared with patients evaluated at the time of MM diagnosis (p=0.03). Very significant statistical differences of plasma cell proliferative (PC-PI) and apoptotic (PC-AI) activity were found when comparing the levels of both the indices of MGUS, SMM and stable/plateau MM group versus the active (progression/relapse) form of MM marked by a higher level of PC-PI (3.2%, p=0.000) and PC-AI (4.8%, p=0.000) in the whole cohort of MM patients, but also in comparison with both the active forms at the time of MM diagnosis or active forms evaluated during various phases of the disease after chemotherapy. Highly significant inverse relationship between PC-PI versus PC-AI was also revealed in the group of patients in the active (progression/relapse) phase of MM (p=0.000). These results revealed importance of measurement not only of proliferative but also of apoptotic plasma cells indices for a complex evaluation of the cells kinetics of plasma cells compartments in patients with MGUS or MM. This study confirmed the initial hypothesis of a common 'inverse relationship between the proliferative (PC-PI) and the apoptosis activity (PC-AI) in plasma cells compartments in patients with MGUS, smoldering, stable/plateau and active (progression/ relapse) forms of MM'.

Abstract
A new method to track the motion of a single particle in the field of a high-finesse optical resonator is analyzed. It exploits sets of near-degenerate higher-order Gaussian cavity modes, whose symmetry is broken by the position dependent phase shifts induced by the particle. Observation of the spatial intensity distribution outside the cavity allows direct determination of the particle's position. This is demonstrated by numerically generating a realistic atomic trajectory using a semiclassical simulation and comparing it to the reconstructed path. The path reconstruction itself requires no knowledge about the forces on the particle. Experimental realization strategies are discussed.

Abstract
Freshwater snails of the family Lymnaeidae are of a great parasitological importance because of the very numerous helminth species they transmit, mainly trematodiases of large medical and veterinary impact. The present knowledge on the genetics of lymnaeids and on their parasite-host inter-relationships is far from being sufficient. The family is immersed in a systematic-taxonomic confusion. The necessity for a tool which enables species distinction and population characterization is evident. This paper aims to review the European Lymnaeidae basing on the second internal transcribed spacer ITS-2 of the nuclear ribosomal DNA. The ITS-2 sequences of 66 populations of 13 European and 1 North American lymnaeid species, including the five generic (or subgeneric) taxa Lymnaea sensu stricto, Stagnicola, Omphiscola, Radix and Galba, have been obtained. The ITS-2 proves to be a useful marker for resolving supraspecific, specific and population relationships in Lymnaeidae. Three different groupings according to their ITS-2 length could be distinguished: Radix and Galba may be considered the oldest taxa (370-406 bp lengths), and Lymnaea s. str., European Stagnicola and Omphiscola (468-491 bp lengths) the most recent, American Stagnicola and Hinkleyia being intermediate (434-450 bp lengths). This hypothesis agrees with the phylogeny of lymnaeids based on palaeontological data, chromosome numbers and radular dentition. ITS-2 sequences present a conserved central region flanked by two variable lateral regions corresponding to the 5' and 3' ends. The number of repeats of two microsatellites found in this conserved central region allows to differentiate Radix from all other lymnaeids. Phylogenetic trees showed four clades: (A) Lymnaea s. str., European Stagnicola and Omphiscola; (B) Radix species; (C) Galba truncatula; and (D) North American stagnicolines. ITS-2 results suggest that retaining Stagnicola as a subgenus of Lymnaea may be the most appropriate and that genus status for Omphiscola is justified. Radix shows a complexity suggesting different evolutionary lines, whereas G. truncatula appears to be very homogeneous. North American and European stagnicolines do not belong to the same supraspecific taxon; the genus Hinkleyia may be used for the American stagnicolines. Genetic distances and sequence differences allowed us to distinguish the upper limit to be expected within a single species and to how different sister species may be. S. palustris, S. fuscus and S. corvus proved to be valid species, but S. turricula may not be considered a species independent from S. palustris. Marked nucleotide divergences and genetic distances detected between different S. fuscus populations may be interpreted as a process of geographic differentiation developping in the present. Among Radix, six valid species could be distinguished: R. auricularia, R. ampla, R. peregra (=R. ovata;=R. balthica), R. labiata, R. lagotis and Radix sp. The information which the ITS-2 marker furnishes is of applied interest concerning the molluscan host specificity of the different trematode species. The phylogenetic trees inferred from the ITS-2 sequences are able to differentiate between lymnaeids transmitting and those non-transmitting fasciolids, as well as between those transmitting F. hepatica and those transmitting F. gigantica. The Fasciola specificity is linked to the two oldest genera which moreover cluster together in the phylogenetic trees, suggesting an origin of the Fasciola ancestors related to the origin of this branch. European Trichobilharzia species causing human dermatitis are transmitted only by lymnaeids of the Radix and Lymnaea s. str.-Stagnicola groups. Results suggest the convenience of reinvestigating compatibility differences after accurate lymnaeid species classification by ITS-2 sequencing. Similarly, ITS-2 sequencing would allow a step forward in the appropriate rearrangement of the actual systematic confusion among echinostomatids.

Abstract
The effect of Bacillus thuringiensis israelensis eluate containing water-soluble exotoxin (M-exotoxin) was observed by its use on cercariae of seven trematode species. To the most sensitive species to the toxic effect of the mentioned toxin belonged schistosome furcocercariae (human species Schistosoma mansoni and avian parasite Trichobilharzia szidati). Under the influence of the toxin, surface syncytial structure (tegument) was separated from underlying tissues, with subsequent disintegration of internal organs connected with disruption of acetabular glands and release of their proteolytic content.

Abstract
Codeine and morphine are endogenous substances. Following administration of exogenous codeine the biotransformation to morphine is catalyzed by CYP2D6, which exhibits a genetic so-called debrisoquine/sparteine polymorphism which is expressed in two phenotypes, the extensive and poor metaboliser phenotypes. Poor metabolisers form only trace amounts of morphine. If endogenous morphine is biosynthesised in humans via similar routes as in the poppy plant, two of the steps involved are mediated by CYP2D6, namely thebaine O-demethylation to oripavine and codeine O-demethylation to morphine. Poor metabolisers should therefore have a much lower endogenous morphine formation than extensive metabolisers. The urinary excretion of endogenous codeine and morphine were investigated in 20 extensive and 20 poor metabolisers of CYP2D6. Substantial interindividual variation in codeine (7-6851 pmol/24 hr) and morphine (32-35471 pmol/24 hr) excretion was observed. However, there were no phenotype-related differences in endogenous codeine and morphine excretion. Administration of the competitive CYP2D6 inhibitor quinidine had no significant effect on endogenous codeine and morphine excretion in extensive metabolisers. In conclusion, in contrast to exogenous codeine O-demethylation to morphine CYP2D6 appears not to be involved in the biosynthesis of morphine in humans.
