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 measure the lifetime of the D_{s}^{+} meson using a data sample of 207 fb^{-1} collected by the Belle II experiment running at the SuperKEKB asymmetric-energy e^{+}e^{-} collider. The lifetime is determined by fitting the decay-time distribution of a sample of 116×10^{3} D_{s}^{+}→ϕπ^{+} decays. Our result is τ_{D_{s}^{+}}=(499.5±1.7±0.9) fs, where the first uncertainty is statistical and the second is systematic. This result is significantly more precise than previous measurements.

Abstract
We report the first search for a nonstandard-model resonance decaying into τ pairs in e^{+}e^{-}→μ^{+}μ^{-}τ^{+}τ^{-} events in the 3.6-10 GeV/c^{2} mass range. We use a 62.8 fb^{-1} sample of e^{+}e^{-} collisions collected at a center-of-mass energy of 10.58 GeV by the Belle II experiment at the SuperKEKB collider. The analysis probes three different models predicting a spin-1 particle coupling only to the heavier lepton families, a Higgs-like spin-0 particle that couples preferentially to charged leptons (leptophilic scalar), and an axionlike particle, respectively. We observe no evidence for a signal and set exclusion limits at 90% confidence level on the product of cross section and branching fraction into τ pairs, ranging from 0.7 to 24 fb, and on the couplings of these processes. We obtain world-leading constraints on the couplings for the leptophilic scalar model for masses above 6.5 GeV/c^{2} and for the axionlike particle model over the entire mass range.

Abstract
We report a measurement of the CP-violating parameters C and S in B^{0}→K_{S}^{0}π^{0} decays at Belle II using a sample of 387×10^{6} BB[over ¯] events recorded in e^{+}e^{-} collisions at a center-of-mass energy corresponding to the ϒ(4S) resonance. These parameters are determined by fitting the proper decay-time distribution of a sample of 415 signal events. We obtain C=-0.04_{-0.15}^{+0.14}±0.05 and S=0.75_{-0.23}^{+0.20}±0.04, where the first uncertainties are statistical and the second are systematic.

Abstract
We present the first measurement of the ratio of branching fractions of inclusive semileptonic B-meson decays, R(X_{e/μ})=B(B→Xeν)/B(B→Xμν), a precision test of electron-muon universality, using data corresponding to 189 fb^{-1} from electron-positron collisions collected with the Belle II detector. In events where the partner B meson is fully reconstructed, we use fits to the lepton momentum spectra above 1.3 GeV/c to obtain R(X_{e/μ})=1.007±0.009(stat)±0.019(syst), which is the most precise lepton-universality test of its kind and agrees with the standard-model expectation.

Abstract
BACKGROUND The colonization of skin with pathogenic, partially antibiotic resistant bacteria is frequently a severe problem in dermatological therapies. For instance, skin colonisation with Staphylococcus aureus is even a disease-promoting factor in atopic dermatitis. The photodynamic inactivation (PDI) of bacteria could be a new antibacterial procedure. Upon irradiation with visible light, a special photosensitizer exclusively generates singlet oxygen. This reactive oxygen species kills bacteria via oxidation independent of species or strain and their antibiotic resistance profile causing no bacterial resistance on its part. OBJECTIVE To investigate the antibacterial potential of a photosensitizer, formulated in a new hydrogel, on human skin ex vivo. METHODS The photochemical stability of the photosensitizer and its ability to generate singlet oxygen in the hydrogel was studied. Antimicrobial efficacy of this hydrogel was tested step by step, firstly on inanimate surfaces and then on human skin ex vivo against S. aureus and Pseudomonas aeruginosa using standard colony counting. NBTC staining and TUNEL assays were performed on skin biopsies to investigate potential necrosis and apoptosis effects in skin cells possibly caused by PDI. RESULTS None of the hydrogel components affected the photochemical stability and the life time of singlet oxygen. On inanimate surfaces as well as on the human skin, the number of viable bacteria was reduced with up to 4.8 log10 being more effective than most other antibacterial topical agents. Histology and assays showed that PDI against bacteria on the skin surface caused no harmful effects in the underlying skin cells. CONCLUSION PDI hydrogel proved to be effective for decolonization of human skin including the potential to act against superficial skin infections. Being a water-based formulation, the hydrogel should be also suitable on the mucosa. The results of the present ex vivo study form a good basis for conducting clinical studies in vivo.

Abstract
Solid tumors have an altered metabolism with a so-called inside-out pH gradient (decreased pHe < increased pHi). This also signals back to tumor cells via proton-sensitive ion channels or G protein-coupled receptors (pH-GPCRs) to alter migration and proliferation. Nothing, however, is known about the expression of pH-GPCRs in the rare form of peritoneal carcinomatosis. Paraffin-embedded tissue samples of a series of 10 patients with peritoneal carcinomatosis of colorectal (including appendix) origin were used for immunohistochemistry to study the expression of GPR4, GPR65, GPR68, GPR132, and GPR151. GPR4 was just expressed weakly in 30% of samples and expression was significantly reduced as compared to GPR56, GPR132, and GPR151. Furthermore, GPR68 was only expressed in 60% of tumors and showed significantly reduced expression as compared to GPR65 and GPR151. This is the first study on pH-GPCRs in peritoneal carcinomatosis, which shows lower expression of GPR4 and GPR68 as compared to other pH-GPCRs in this type of cancer. It may give rise to future therapies targeting either the TME or these GPCRs directly.

Abstract
TRPCs (transient receptor potential classical or cation channels) play a crucial role in tumor biology, especially in the Ca2+ homeostasis in cancer cells. TRPC4 is a pH-sensitive member of this family of proteins. As solid tumors exhibit an inversed pH-gradient with lowered extracellular and increased intracellular pH, both contributing to tumor progression, TRPC4 might be a signaling molecule in the altered tumor microenvironment. This is the first study to investigate the expression profiles of TRPC4 in common skin cancers such as basal cell carcinoma (BCC), squamous cell carcinoma (SCC), malignant melanoma (MM) and nevus cell nevi (NCN). We found that all SCCs, NCNs, and MMs show positive TRPC4-expression, while BCCs do only in about half of the analyzed samples. These data render TRPC4 an immunohistochemical marker to distinguish SCC and BCC, and this also gives rise to future studies investigating the role of TRPC4 in tumor progression, and especially metastasis as BCCs very rarely spread and are mostly negative for TRPC4.

Abstract
Due to its high metastatic potential, malignant melanoma is one of the deadliest skin cancers. In melanoma as well as in other cancers, acidification of the tumor microenvironment (=TME, inverse pH-gradient) is a well-known driver of tumor progression and metastasis. Membrane-bound receptors, such as the proton-sensitive GPCR (pH-GPCR) GPR4, are considered as potential initiators of the signalling cascades relevant to malignant transformation. In this study, we investigated the pH-dependent migration of GPR4 wildtype/overexpressing SK-Mel-28 cells using an impedance-based electrical wounding and migration assay and classical Boyden chamber experiments. Migration of GPR4 overexpressing SK-Mel-28 cells was enhanced in a range of pH 6.5-7.5 as compared to controls in the impedance-based electrical wounding and migration assay. In Boyden chamber experiments, GPR4 overexpression only increased migration at pH 7.5 in a Matrigel-free setup, but not at pH 6.5. Results indicate that GPR4 is involved in the migration of melanoma cells, especially in the tumor periphery, and that this process is affected by pH in the TME.

Abstract
COMPASS is a multi-purpose fixed-target experiment at CERN’s M2 beam line aimed at studying the structure and spectrum of hadrons. It has collected the so far world’s largest data set on diffractive production of the K−π−π+ final state, which in principle gives access to all strange mesons. Based on this data set, we performed an elaborate partial-wave analysis. It reveals signals in the mass region of well-known states, such as the K*2(1430). In addition, we found indications for a resonance-like signal in the mass region of the K(1630). This state would be a supernumerary state and hence could be a candidate for an exotic strange meson. The partial-wave analysis is limited in some areas by the limited kinematic coverage of the final-state particle identification of the COMPASS setup. To overcome this limitation, we propose a new high-precision strange-meson spectroscopy measurement at the AMBER experiment, which will be located at CERN’s M2 beam line.

Abstract
TWIK-related acid-sensitive potassium channels TASK1 and TASK3, as well as the G-protein-coupled receptors GPR31 and GPR151, are proton-sensitive membrane proteins. They can be activated or inhibited by low extracellular pH (pHe), which is a hallmark of the tumor microenvironment in solid tumors. However, the role of these channels in the development of skin tumors is still unclear. In this study, we investigated the expression profiles of TASK1, TASK3, GPR31 and GPR151 in squamous cell carcinomas (SCCs), basal cell carcinomas (BCCs), nevus cell nevi (NCN), and malignant melanomas (MMs). We performed immunohistochemistry using paraffin-embedded tissue samples from patients and found that most skin tumors express TASK1/3 and GPR31/151. The results show that BCCs are often negative for GPR31/151 as well as for TASK1/3, while nearly all SCCs express these markers. MMs and NCN show similar expression patterns. However, some tumors show a decreasing TASK1/3 expression in deeper dermal tumor tissue, while GPCRs were expressed more evenly. The lower frequency of GPR31/151 and TSAK1/3 expression in BCCs when compared to SCCs is a novel histological feature distinguishing these two entities. Moreover, BCCs also show lower expression of GPR31/151 and TASK1/3 as compared to NCN and MMs.

Abstract
The COMPASS Collaboration experiment recently discovered a new isovector resonancelike signal with axial-vector quantum numbers, the a_{1}(1420), decaying to f_{0}(980)π. With a mass too close to and a width smaller than the axial-vector ground state a_{1}(1260), it was immediately interpreted as a new light exotic meson, similar to the X, Y, Z states in the hidden-charm sector. We show that a resonancelike signal fully matching the experimental data is produced by the decay of the a_{1}(1260) resonance into K^{*}(→Kπ)K[over ¯] and subsequent rescattering through a triangle singularity into the coupled f_{0}(980)π channel. The amplitude for this process is calculated using a new approach based on dispersion relations. The triangle-singularity model is fitted to the partial-wave data of the COMPASS experiment. Despite having fewer parameters, this fit shows a slightly better quality than the one using a resonance hypothesis and thus eliminates the need for an additional resonance in order to describe the data. We thereby demonstrate for the first time in the light-meson sector that a resonancelike structure in the experimental data can be described by rescattering through a triangle singularity, providing evidence for a genuine three-body effect.

Abstract
Configural Frequency Analysis (CFA) is a useful statistical method for the analysis of multiway contingency tables and an appropriate tool for person-oriented or person-centered methods. In complex contingency tables, patterns or configurations are analyzed by comparing observed cell frequencies with expected frequencies. Significant differences between observed and expected frequencies lead to the emergence of Types and Antitypes. Types are patterns or configurations which are significantly more often observed than the expected frequencies; Antitypes represent configurations which are observed less frequently than expected. The R-package confreq is an easy-to-use software for conducting CFAs; another useful shareware to run CFAs was developed by Alexander von Eye. Here, CFA is presented based on the log-linear modeling approach. CFA may be used together with interval level variables which can be added as covariates into the design matrix. In this article, a real data example and the use of confreq are presented. In sum, the use of a covariate may bring the estimated cell frequencies closer to the observed cell frequencies. In those cases, the number of Types or Antitypes may decrease. However, in rare cases, the Type-Antitype pattern can change with new emerging Types or Antitypes.

Abstract
The proton-sensing GPCRs (pH-GPCRs) GPR4 (GPR19), TDAG8 (GPR65, T-cell death associated gene 8), OGR1 (GPR68, ovarian cancer GPCR1), and G2A (GPR132, G2 accumulation protein) are involved in sensing and transducing changes in extracellular pH (pHe). Extracellular acidification is a central hallmark of solid cancer. pH-GPCR function has been associated with cancer cell proliferation, adhesion, migration and metastasis, as well as with modulation of the immune system. Little is known about the expression levels and role of pH-GPCRs in skin cancer. To better understand the functions of pH-GPCRs in skin cancer in vivo, we examined the expression-profiles of GPR4, TDAG8, OGR1 and G2A in four common skin tumors, i.e. squamous cell carcinoma (SCC), malignant melanoma (MM), compound nevus cell nevi (NCN), basal cell carcinoma (BCC). We performed immunohistochemistry and immunofluorescence staining on paraffin-embedded tissue samples acquired from patients suffering from SCC, MM, NCN or BCC. We show the expression of pH-GPCRs in four common skin cancers. Different expression patterns in the investigated skin cancer types indicate that the different pH-GPCRs may have distinct functions in tumor progression and serve as novel therapeutic targets.

Abstract
Skeletal muscle is under inhibitory homeostatic regulation by multiple ligands of the transforming growth factor-β (TGFβ) superfamily. Follistatin is a secreted protein that promotes muscle growth and function by sequestering these ligands extracellularly. In the present study, we evaluated the potential of ACE-083 – a locally acting, follistatin-based fusion protein – as a novel therapeutic agent for focal or asymmetric myopathies. Characterization of ACE-083 in vitro revealed its high affinity for heparin and extracellular matrix while surface plasmon resonance and cell-based assays confirmed that ACE-083 binds and potently neutralizes myostatin, activin A, activin B and growth differentiation factor 11 (GDF11). Intramuscular administration of ACE-083 caused localized, dose-dependent hypertrophy of the injected muscle in wild-type mice and mouse models of Charcot-Marie-Tooth disease (CMT) and Duchenne muscular dystrophy, with no evidence of systemic muscle effects or endocrine perturbation. Importantly, ACE-083 also increased the force of isometric contraction in situ by the injected tibialis anterior muscle in wild-type mice and disease models and increased ankle dorsiflexion torque in CMT mice. Our results demonstrate the potential of ACE-083 as a therapeutic agent for patients with CMT, muscular dystrophy and other disorders with focal or asymmetric muscle atrophy or weakness.

Abstract
BACKGROUND In humans, there are four known proton-sensing G-Protein-coupled receptors (pH-GPCRs): GPR4 (GPR19), TDAG8 (GPR65, T-cell death-associated gene 8), OGR1 (GPR68, ovarian cancer GPCR1) and G2A (GPR132, G2 accumulation protein). They are known to be involved in sensing changes of extracellular proton concentrations in the acidic microenvironment of tumors, which leads to altered cell proliferation, migration, metastasis, immune cell function and inflammation. However, little is known about the expression of pH-GPCRs in the skin and especially skin cancers. AIM We studied the expression of pH-GPCRs in selected skin cancers, that is Merkel cell carcinoma (MCC), dermatofibrosarcoma protuberans (DFSP), atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS). METHODS We did immunohistochemistry and immunofluorescence to analyse the expression of GPR4, TDAG8, OGR1 and G2A using paraffin-embedded tissue samples (n = 4, exceptions: PDS GPR4/GPR65 n = 5, AFX GPR132 n = 3) from patients suffering from MCC, DFSP, AFX and PDS. RESULTS (a) GPR4 was expressed on all AFX and PDS specimens. All AFX and MCC showed a positive expression of G2A. All PDS exhibited a strong positive expression of G2A. (b) MCCs neither expressed GPR4 nor TDAG8. All DFSP showed no expression of TDAG8. (c) For any other combination of GPCR and skin disease, we found positive/negative mixed results. CONCLUSIONS These are the first results on pH-GPCRs in selected skin cancers. We provide evidence that these GPCRs are differentially expressed on the various types of skin cancers and that they can potentially be addressed as a therapeutic target in extensive disease.

Abstract
The first measurement of transverse-spin-dependent azimuthal asymmetries in the pion-induced Drell-Yan (DY) process is reported. We use the CERN SPS 190 GeV/c π^{-} beam and a transversely polarized ammonia target. Three azimuthal asymmetries giving access to different transverse-momentum-dependent (TMD) parton distribution functions (PDFs) are extracted using dimuon events with invariant mass between 4.3 GeV/c^{2} and 8.5 GeV/c^{2}. Within the experimental uncertainties, the observed sign of the Sivers asymmetry is found to be consistent with the fundamental prediction of quantum chromodynamics (QCD) that the Sivers TMD PDFs extracted from DY have a sign opposite to the one extracted from semi-inclusive deep-inelastic scattering (SIDIS) data. We present two other asymmetries originating from the pion Boer-Mulders TMD PDFs convoluted with either the nucleon transversity or pretzelosity TMD PDFs. A recent COMPASS SIDIS measurement was obtained at a hard scale comparable to that of these DY results. This opens the way for possible tests of fundamental QCD universality predictions.

Abstract
The COMPASS Collaboration at CERN has measured diffractive dissociation of 190 GeV/c pions into the π(-)π(-)π(+) final state using a stationary hydrogen target. A partial-wave analysis (PWA) was performed in bins of 3π mass and four-momentum transfer using the isobar model and the so far largest PWA model consisting of 88 waves. A narrow peak is observed in the f0(980)π channel with spin, parity and C-parity quantum numbers J(PC)=1(++). We present a resonance-model study of a subset of the spin-density matrix selecting 3π states with J(PC)=2(++) and 4(++) decaying into ρ(770)π and with J(PC)=1(++) decaying into f0(980)π. We identify a new a1 meson with mass (1414(-13)(+15)) MeV/c2 and width (153(-23)(+8)) MeV/c2. Within the final states investigated in our analysis, we observe the new a1(1420) decaying only into f0(980)π, suggesting its exotic nature.

Abstract
Several recent studies have shown evidence supporting the general knowledge that tumour cells exhibit changes in metabolism. It is becoming increasingly important to understand how these metabolic changes in tumour cells promote carcinogenesis and disease progression. We recently discovered a lack of methylthioadenosine phosphorylase (MTAP) expression in melanoma, which resulted in an accumulation of the metabolite 5'-methylthioadenosine (MTA) in melanoma cells and in the extracellular environment. MTA was shown to affect cell proliferation of surrounding stroma cells and cell invasiveness and the activation of the transcription factor activator protein-1 (AP-1) in melanoma cells. In this study, we addressed the regulation of cellular signalling by extracellular MTA accumulation. By focusing on putative receptors that could modulate MTA signalling, we identified the adenosine receptor ADORA2B as an important candidate. Knockdown experiments and the use of specific agonists and antagonists confirmed a link between MTA and AP-1 signalling through the ADORA2B receptor. Interestingly, stimulation of the cells with MTA did not result in activation of the classical cyclic adenosine monophosphate (cAMP) signalling cascades or in Ca(2+)-dependent signalling. We instead showed protein kinase C (PKC) signalling to be involved in MTA-mediated AP-1 activation. In summary, we identified ADORA2B to be the specific receptor and signalling pathway for the metabolite MTA. These findings may influence the use of MTA in a therapeutic manner.

Abstract
AIM At the interface of tissue and capillaries, pericytes (PC) may generate electrical signals to be conducted along the skeletal muscle vascular network, but they are functionally not well characterized. We aimed to isolate and cultivate muscle PC allowing to analyse functional properties considered important for signal generation and conduction. METHODS Pericytes were enzymatically isolated from hamster thigh muscles and further selected during a 16-30 days' cultivation period. PC markers were studied by fluorescence activated cell scanning (FACS) and immunocytochemistry. Electrical properties of the cultured PC were investigated by patch clamp technique as well as the membrane potential sensitive dye DiBAC(4) (3). RESULTS The cultured cells showed typical PC morphology and were positive for NG2, alpha smooth muscle actin, PDGFR-β and the gap junction protein Cx43. Expressions of at least one single or combinations of several markers were found in 80-90% of subpopulations. A subset of the patched cells expressed channel activities consistent with a Kv1.5 channel. In vivo presence of the channels was confirmed in sections of hamster thigh muscles. Interleukin-8, a myokine known to be released from exercising muscle, increased the expression but not the activity of this channel. Pharmacologic stimulation of the channel activity by flufenamic acid induced hyperpolarization of PC alone but not of endothelial cells [human umbilical vein endothelial cells (HUVEC)] alone. However, hyperpolarization was observed in HUVEC adjacent to PC when kept in co-culture. CONCLUSION We established a culture method for PC from skeletal muscle. A first functional characterization revealed properties which potentially enable these cells to generate hyperpolarizing signals and to communicate them to endothelial cells.

Abstract
Recent studies have shown that a loss of methylthioadenosine phosphorylase (MTAP) gene expression exerts a tumor-promoting effect, including induction of invasiveness, enhanced cell proliferation, and resistance against cytokines. To date, the molecular mechanisms underlying these effects remain unknown. Since the loss of MTAP expression resulted in induced secretion of 5'-deoxy-5'-(methylthio)adenosine (MTA), we hypothesized that MTA might modulate the observed effects. We first determined MTA levels produced by tumor cells in vitro and in situ by means of stable isotope dilution liquid chromatography tandem mass spectrometry. Subsequently, we revealed induction of matrix metalloproteinase (MMP) and growth factor gene expression in melanoma cells accompanied by enhanced invasion and vasculogenic mimicry. In addition, MTA induced the secretion of basis fibroblast growth factor (bFGF) and MMP3 from fibroblasts and the upregulation of activator protein-1 (AP-1) activity in melanoma cells and fibroblasts. In summary, we demonstrated a tumor-supporting role of MTA.

Abstract
Nephronectin (POEM) was originally identified as a factor involved in tissue morphogenesis. POEM has several characteristics of a matrix protein including an arg-gly-asp binding domain site that is recognized by integrins. Recently, deregulation of POEM was found in breast cancer. We therefore speculate that deregulation of POEM expression plays a role in the development or progression of malignant melanoma. Thus, we evaluated melanoma cell lines and tissue samples of malignant melanoma for POEM transcription. We found that POEM expression was reduced or lost in most cell lines and in all tumor samples analyzed. Reduced POEM expression occurred as early as in primary tumors detected by both immunohistochemical and reverse transcription-polymerase chain reaction analyses. Functional assays with stable POEM transfected cell lines revealed that POEM expression increased cell adhesion and decreased cell migration and invasion supporting a role of POEM in tumor progression. Interestingly, integrin alpha-8 expression, which was described as a receptor for POEM, is enhanced in malignant melanoma. Our studies thus indicate that loss of POEM expression may contribute to melanoma progression.

Abstract
The human gene Hugl-1 (Llgl/Lgl1) has significant homology to the Drosophila tumor suppressor gene lethal(2)giant larvae (lgl). The lgl gene codes for a cortical cytoskeleton protein, Lgl, that is involved in maintaining cell polarity and epithelial integrity. We speculate that Hugl-1 might play a role in epithelial-mesenchymal transition (EMT) and that loss of Hugl-1 expression plays a role in the development or progression of malignant melanoma. Thus, we evaluated melanoma cell lines and tissue samples of malignant melanoma for loss of Hugl-1 transcription. We found that Hugl-1 was downregulated or lost in all cell lines and in most of the tumor samples analysed, and that these losses were associated with advanced stage of the disease. Reduced Hugl-1 expression occurred as early as in primary tumors detected by both immunohistochemical and reverse transcription-polymerase chain reaction (RT-PCR) analysis. Functional assays with stable Hugl-1-transfected cell lines revealed that Hugl-1 expression increased cell adhesion and decreased cell migration. Further, downregulation of MMP2 and MMP14 (MT1-MMP) and re-expression of E-cadherin was found in the Hugl-1-expressing cell clones supporting a role of Hugl-1 in EMT. Our studies thus indicate that loss of Hugl-1 expression contributes to melanoma progression.

Abstract
The methylthioadenosine phosphorylase (MTAP) gene is localized in the chromosomal region 9p21. Here, frequently homozygous deletions occur in several kinds of cancer associated with the loss of tumour suppressor genes as p16 and p15. The aim of this study was to analyse MTAP expression in hepatocellular carcinoma (HCC) and to get an insight into the regulation and functional role of MTAP in hepatocancerogenesis. Compared with primary human hepatocytes MTAP expression was markedly downregulated in three different HCC cell lines as determined by real-time PCR and western blotting. This was not due to genomic losses or mutations but to promoter-hypermethylation. Reduced MTAP-expression was confirmed in vivo in HCC compared with non-cancerous liver tissue on both mRNA and protein levels. To study the functional relevance of the downregulated MTAP expression in HCC, MTAP expression was re-induced in HCC cell lines by stable transfection. In these MTAP re-expressing cell clones the invasive potential was strongly reduced, whereas no effects on cell proliferation were observed in comparison with mock transfected cell clones. Furthermore, in MTAP re-expressing cells interferon (IFN)-alpha and IFN-gamma induced a significantly stronger inhibition of cell proliferation than in mock transfected cells. In conclusion, our results suggest a functional role of MTAP inactivation in HCC development and invasiveness. Furthermore, in the light of a recent report revealing an association between MTAP activity and IFN sensitivity, our findings may have clinical significance for therapeutic strategies.

Abstract
Methylthioadenosine phosphorylase (MTAP) is known as a ubiquitously expressed house keeping gene important in biochemical salvage processes. The MTAP gene is localized on the human chromosomal region 9p21, a region often deleted in cancer. Recently, several groups including our own have shown that MTAP serves as a tumour suppressor gene. The aim of this study was to analyse the role of MTAP in colon carcinoma and normal colon epithelium and the regulation of gene expression. To examine MTAP RNA and protein expression, we screened six colon carcinoma cell lines and human primary colon epithelial cells by RT-PCR and immunoblotting. MTAP expression was confirmed in vivo by immunohistochemical staining of normal colon tissue compared to adenoma and colon carcinoma. Interestingly, we found strong MTAP mRNA and protein expression by colon carcinoma cell lines but no expression by colonic epithelial cells. To analyse the regulation of MTAP expression, promoter studies were performed and revealed control of MTAP expression by LEF/TCF/beta-catenin. Furthermore, we demonstrated a significant correlation between MTAP protein expression and tumour progression as the intensity of MTAP protein staining increased from normal tissue to carcinoma. In addition, the recently postulated association between MTAP activity and interferon (IFN) sensitivity was confirmed in colon epithelial cells showing only little response to IFN-gamma, in contrast to the carcinoma cell lines. In summary, these data indicate for the first time that MTAP is not expressed in normal human colonic epithelium but is strongly upregulated in colon carcinoma. This finding may be of clinical significance concerning the homeostasis of normal colon epithelium and potential treatment of colon carcinoma.

Abstract
Homozygous deletions of human chromosomal region 9p21 occur frequently in malignant melanoma and are associated with the loss of the tumor suppressor genes p16(INK4a) and p15(INK4b). In the same chromosomal region the methylthioadenosine phosphorylase (MTAP) gene is localized and therefore may also serve as a tumor suppressor gene. The aim of this study was to analyze MTAP mutations and expression patterns in malignant melanomas. To examine the MTAP gene and expression of MTAP protein we screened 9 human melanoma cell lines and primary human melanocytes by reverse transcriptase-polymerase chain reaction, sequencing, and immunoblotting. Analyzing the melanoma cell lines we found significant down-regulation of MTAP mRNA expression. In only one cell line, HTZ19d, this was due to homozygous deletion of exon 2 to 8 whereas in the other cell lines promoter hypermethylation was detected. MTAP expression was further analyzed in vivo by immunohistochemical staining of 38 tissue samples of benign melanocytic nevi, melanomas, and melanoma metastases. In summary, we demonstrate significant inverse correlation between MTAP protein expression and progression of melanocytic tumors as the amount of MTAP protein staining decreases from benign melanocytic nevi to metastatic melanomas. Our results suggest an important role of MTAP inactivation in the development of melanomas. This finding may be of great clinical significance because recently an association between MTAP activity and interferon sensitivity has been suggested.

Abstract
The acute effect of the anti-ischemic potassium channel opener nicorandil on glucose tolerance and post-challenge insulin levels was investigated in 11 subjects (6 males and 5 females, age 59 +/- 2 years) with borderline fasting blood glucose in a single blinded randomised study. All participants were submitted to two oral glucose tolerance tests in randomised order, once without any premedication and once 30 minutes after oral administration of 20 mg nicorandil. This single dose of nicorandil significantly increased blood glucose levels at 120 minutes (173 +/- 16 vs. 150 +/- 11 mg/dl, p < 0.05 by ANOVA) and 180 minutes (106 +/- 11 vs. 88 +/- 7 mg/dl, p < 0.05 by ANOVA) after ingestion of 75 mg of glucose. Serum insulin levels were not significantly altered. In conclusion we suggest that controlled studies in patients with coronary artery disease should be performed to investigate whether long term treatment with nicorandil increases progression rates from impaired glucose tolerance to type-II diabetes and/or from normal to impaired glucose tolerance with a possibly negative impact on the course of cardiovascular disease in comparison to conventional anti-anginal drugs.

Abstract
Antioxidant effects may constitute part of the possible antiatherogenic effects of the amino acid L-arginine. These antioxidant properties were further characterized in a model of lipoprotein oxidation. Oxidation of lipoproteins in unfractionated human serum was continuously monitored by a fluorescent probe. The antioxidant effects of L-arginine, N-alpha-acetyl-arginine and vitamin E in combination with L-arginine were measured after initiation of free radical generation with either copper or 2,2'-azobis(2-amidinopropane) hydrochloride (AAPH). The half-time of the fast propagation rate for copper-induced lipoprotein oxidation increased after incubation with L-arginine in a dose-dependent manner (P < 0.01). N-alpha-acetyl-arginine did not show such effects. Vitamin E and L-arginine show different effects on copper-induced oxidation, the former increasing only lag-time, the latter increasing only propagation rate, and do not have reciprocal effects. In contrast to copper-induced oxidation, L-arginine increased the lag-time of AAPH-induced lipoprotein oxidation (P < 0.01), with no effect on the propagation rate at physiological concentrations. Again, N-alpha-acetyl-arginine did not show any antioxidant effects. Our experiments provide further evidence that mechanisms other than serving as a substrate for the NO-synthase could be involved in the antiatherosclerotic effect of L-arginine. In addition, our experiments clearly show, that the antioxidant effect of L-arginine is due to a chemical moiety different from that serving as the substrate for NO biosynthesis.

Abstract
OBJECTIVE To investigate how extracorporal cholesterol lowering therapy affects circulating leptin levels in patients with ravenous hunger after treatment and permanent weight gain. DESIGN A case report. SUBJECT 51 y old caucasian male patient with moderate chronic renal failure. MEASUREMENTS Serum Leptin concentration (RIA, Linco Research Inc, St. Louis, MO, USA), total cholesterol, low density lipoprotein cholesterol, blood glucose levels, calorie intake by food records. RESULTS During treatment total cholesterol was reduced by 50%. Serum Leptin levels showed a 42% reduction at the end of treatment, that by far exceeds the physiological diurnal variation. Calorie intake was significantly increased on days of treatment. CONCLUSION We conclude that this artificial reduction in circulating leptin plays an important role in the pathogenesis of ravenous hunger and weight gain under extracorporal cholesterol lowering therapy in this case.

Abstract
OBJECTIVE To study the effect of a standardised training programme focusing on maintenance of fat free mass during weight reduction by energy reduction in obese children. DESIGN Randomised trial of physical training programme and dietary advice (group A) versus dietary advice alone (group B). SUBJECTS Thirty obese children and adolescents (14 group A, 16 group B) participated in the 12 week long programme; 20 children (10 group A, 10 group B) were also reassessed after one year. MEASUREMENTS Fat free mass was estimated from the resistance index, obtained by bioelectrical impedance analysis at baseline, after four, eight, and 12 weeks in all subjects, and after one year in 20 subjects. RESULTS The mean (SD) change in fat free mass was significantly different between the two groups after 12 weeks (group A, 2.68 (3.74) kg; group B, 0.43 (1.65) kg). The change in body weight after one year was inversely correlated with the change in fat free mass after 12 weeks (r = -0. 44), as assessed in the 20 subjects. CONCLUSIONS A standardised training programme as used in this study can prevent reduction in fat free mass during weight loss in obese children. Reduction in fat free mass during weight reduction might be a risk factor for regain of weight.

Abstract
BACKGROUND In patients with coronary artery disease (CAD), a rate of restenosis as high as 50% is observed after percutaneous transluminal coronary angioplasty (PTCA). Frequently, this results in further revascularization procedures. Lifestyle intervention has been shown to slow the progression of CAD and to reduce cardiovascular events after myocardial infarction. However, no information exists whether such treatment influences the rate of restenosis in patients with CAD. The present study was performed to investigate the effects of an intensified lifestyle intervention on the need for further revascularization procedures in patients with established CAD after successful PTCA. DESIGN A total of 60 patients were included and randomized to either conventional treatment by cardiologists and general practitioners or additional intensified lifestyle intervention in a diabetes and metabolism outpatient clinic for 12 months. The mean observation time after successful PTCA was 26 months. The primary outcome variable was the need for further revascularization procedures because of clinical restenosis. Secondary outcome variables were lifestyle-related measures. RESULTS Intervention resulted in a reduction in body weight and blood pressure, and in increased physical activity. Furthermore, nutritional habits were changed towards less fat intake, and body composition changed towards a higher proportion of fat-free mass. The need for further revascularization procedures was reduced from a total of 14 out of 32 in the conventionally treated group to 3 out of 28 in the intervention group. This resulted in an event-free survival probability of 0.89 in the intervention group and 0.57 in the control group (P = 0.0055, log rank) with a resulting relative risk of 0.26 (95% CI 0.09-0.74). CONCLUSION In conclusion, our data strongly suggest that intensified lifestyle modification is able to reduce the need for further revascularization procedures after PTCA in patients with CAD.

Abstract
BACKGROUND Post-ischaemic reactive hyperaemia in the forearm has been suggested as a marker of resistance vessel function. The contribution of forearm composition to the kinetics of reactive hyperaemia is largely unknown. The body composition of men and women differs in that women have a higher body fat content and less lean body mass. METHODS In the present study, we investigated whether the kinetics of reactive hyperaemia in the forearm in 14 healthy subjects (seven men and seven women) show gender-specific differences and whether forearm composition contributes to such differences. RESULTS Peak reactive hyperaemic flow as well as 1-min-flow debt repayment (measured by venous occlusion plethysmography) were significantly higher in male than in female study participants. This difference was explained to > 60% by gender-specific differences in forearm relative muscle mass (as determined by magnetic resonance imaging). The half-life of the reactive hyperaemic response, on the other hand, was not different between men and women and did not show an association with forearm muscle. CONCLUSION Our results demonstrate that forearm composition must be considered if peak reactive hyperaemic or flow debt repayment is used as a target, and that dynamic measurements of the reactive hyperaemic process are more suitable to describe the function of resistance arteries than single-point observations.

Abstract
BACKGROUND AND OBJECTIVES Immunosuppression associated with blood transfusion may influence postoperative infection rates. It may also affect the prognosis of patients treated surgically for colorectal cancer. To control this effect, study protocols have applied autologous blood donation programs, which are thought to be immunologically neutral. However, evidence has emerged that blood donation itself might have suppressive effects on natural killer (NK) cell activities. At present, there are no data available on the effects of autologous blood transfusion on NK or lymphokine-activated killer (LAK) cells. This might be of interest as LAK cells may be active in tumor control. MATERIALS AND METHODS 26 patients who underwent surgical resection for colorectal cancer, were assigned at random into two groups: (1) autologous blood donation and transfusion, or (2) allogeneic blood transfusion. NK and LAK activities were determined before blood donation, at surgery, and on the 3rd and 8th postoperative day. RESULTS Blood donation induced a small decrease in NK and LAK activities. The postoperative courses of the two groups differed. In the allogeneic group, NK activity (-50%, p = 0.018) and LAK activity decreased (-60.7%, p = 0.043), whereas in the autologous group the decline in LAK was less pronounced (-33.7%, p = 0.091), and their NK activity even increased (+17.4%, p = 0.315). NK activity was modulated differently in the two study groups (0.0036). Differences in LAK activities were found between the 3rd and 8th day postoperatively (p = 0.354). CONCLUSIONS In patients receiving autologous blood transfusion, postoperative suppressed NK and LAK activities were modulated. This implies that autologous blood transfusion is not immunologically neutral, but has an intrinsic immunomodulatory potential.

Abstract
Concentrations of 14 trace elements (Bi, Cd, Co, Cs, Cu, Hg, Mn, Pb, Rb, Sb, Sn, Sr, Tl, and Zn) were determined by inductively coupled plasma mass spectrometry (ICP-MS) in 120 whole-blood and 121 plasma samples of 56 patients with angiographically documented coronary heart disease (CHD). One serum and two whole-blood reference materials were analyzed for quality control. At baseline, patients had elevated Co plasma as well as diminished Cu blood concentrations compared to healthy adults. The Zn concentrations in whole blood were below or at the lower end of the normal range, but the concentrations in plasma were elevated. All other trace elements were within the normal concentration ranges for healthy adults. After initial investigations, patients were randomly assigned to an experimental group (N = 27) and to a usual care group (N = 29). Experimental group patients were prescribed a lifestyle program that included a low-fat diet and a weekly moderate exercise. Patients were examined at baseline, after 6 and 12 mo for clinical assessment and fasting venous blood samples. No significant time-course changes in concentrations of trace elements in blood and plasma during the clinical treatment in both groups of patients could be observed. The experimental group patients lost weight and had lower blood pressure after 12 mo compared to baseline. The interventional therapy reduced the need for further revascularization procedures.

Abstract
The present study was carried out to evaluate the effect of a low-dose intravenous supplementation of L-arginine on insulin-mediated vasodilatation and insulin sensitivity. The study was performed in healthy subjects (n = 7) and patients with obesity (n = 9) and non-insulin-dependent diabetes mellitus (NIDDM) (n = 9). Insulin-mediated vasodilatation was measured by venous occlusion plethysmography during the insulin suppression test, evaluating insulin sensitivity. Experiments were performed twice in each subject in the presence or absence of a concomitant infusion of L-arginine (0.52 mg kg-1 min-1). L-Arginine restored the imparied insulin-mediated vasodilatation observed in obesity (22.4 +/- 4.1%, P < 0.01 vs. without L-arginine) and NIDDM (20.3 +/- 3.2%, P < 0.01 vs. without L-arginine). In healthy subjects, no effect on insulin mediated-vasodilatation was observed (24.8 +/- 3.1% vs. 21.4 +/- 3.1%). Insulin sensitivity was improved significantly (P < 0.001) in all three groups by infusion of L-arginine. No effect of L-arginine was observed on insulin, insulin-like growth factor I (IGF-I), free fatty acids (FFAs) or C-peptide levels during the insulin suppression test. Our data indicate that defective insulin-mediated vasodilatation in obesity and NIDDM can be normalized by intravenous L-arginine. Furthermore, L-arginine improves insulin sensitivity in obese patients and NIDDM patients as well as in healthy subjects, indicating a possible mechanism that is different from the restoration of insulin-mediated vasodilatation.
