Abstract: Low trophic aquaculture (LTA), such as bivalve farming, offers promising avenues to supply sustainable seafood and aquafeed. While bivalve farming usually occurs in highly productive coastal areas which already support numerous human activities and suffer from environmental pressures, numerical tools offer a promising avenue to explore and assess biomass production potential and associated ecosystemic impacts for further development of the industry and prospection of new exploitation sites. In this study, we coupled an ecophysiological model, the dynamic energy budget theory (DEB), with an ecosystem model (NORWECOM.E2E) to simulate blue mussel Mytilus spp. farming production and effects based on the food web in the mesotrophic Hardangerfjord in western Norway. We tested several levels of fjord-scale farming intensity and assessed 2 production purposes: aquafeed and human consumption. Results suggested the Hardangerfjord could host large-scale mussel farming for both purposes. However, large exploitation schemes displayed detrimental effects on individual mussel growth (39% less wet mass after 2 yr) and especially on secondary production (decrease of 33% after 1 yr) due to acute trophic competition. Simulations showed short production cycles for aquafeed were more efficient to exploit primary production, since young and small mussels have lower maintenance and reproduction costs. Dissolved nutrient inputs from salmonid farms had marginal effects on primary production (

Subjects: Physiology (medical), Cardiology and Cardiovascular Medicine
Abstract: Funding Acknowledgements Type of funding sources: Private company. Main funding source(s): Medtronic. Background Left bundle branch block (LBBB) might be the first finding of cardiovascular diseases but it is also the target of cardiac resynchronization therapy (CRT) in heart failure (HF) with reduced ejection fraction (HFrEF). LBBB prognosis and the implication of CRT in an unselected real-world setting are of great potential clinical impact. Methods A central ECG database together with national registries has been screened to identify LBBB patients. Cox models were fitted to assess the hazard ratio (HR) of death, cardiovascular death (CVD) and HF hospitalization (HFH) according to gender and CRT use. A subdistribution of the hazard ratio (SHR) was used to account for non-cardiovascular death as a competing risk. Logistic regression was fitted to investigate characteristics associated with CRT use. Results Of 5359 patients with LBBB and QRS duration over 150ms, 36% were female. The median age was 76 years and males had a significantly higher risk of death after 5 years from the LBBB diagnosis. CRT, when indicated, has a large benefit on all-causes of death (HR: 0.53, 95% confidence intervals (CI): 0.42-0.67), CVD (HR: 0.53 CI: 0.39-0.71) and HFH (HR: 0.71 CI: 0.60-0.82), especially in the first 5 years after the indication. These results are consistent with the competing risk analysis. Conclusion In an unselected LBBB population, CRT is underused but extremely beneficial. Therefore it’s crucial to find ways of better implementing and understanding CRT utilization, focusing on characteristics that influence recommendations.

Abstract: Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): Supported by Swedish Heart and Lung foundation and Stockholm County Council. Background/Introduction Cardiac resynchronization therapy (CRT) is a valuable treatment in selected patients with heart failure (HF) but is still underutilized. Aim We compared three informative data sources, which enrolled patients with HF at different organization setting and identified clinical, organizational, and level of care factors linked to CRT implantation in these cohorts. Methods Data from three large cohorts of patients with HF were compared. Patients with HF with reduced ejection fraction (HFrEF) in an ESC HF-Long Term Registry (ESC-HF-LT, n=25,621), a National HF Registry - Swede HF (n=156,621) and in the ESC-CRT Survey II (n=11088, all receiving CRT across 42 ESC countries), contributed data to the analysis. The ESC Survey II recruited patients at implanting centers, ESC-HF-LT at HF centers, whereas SwedeHF enrolled HF patients at different levels of care. Firstly, we compared patient characteristics, socio-economic and organizational factors between cohorts as well as between overlapping countries participating both in CRT Survey II and ESC HF LT. Secondly, we identified independent predictors of CRT use in the two registries using multivariable logistic regressions. Results Of the 1031 patients in ESC-HF-LT and the 5008 patients in Swede-HF, CRT was not used in 53-75 % of guideline- indicated patients. Women constituted 22% and median age ranged between 68-72 years. Guideline Directed Medical Therapy (GDMT), atrial fibrillation, previous myocardial infarction (SwedeHF) and HF hospitalization (ESC-HF-LT) was associated with more CRT use as was enrollment at university hospital and follow-up at HF center/Hospital. In Swede-HF above median income and higher education level were also independently associated with use of CRT. In the ESC-CRT Survey II (n=11.088) all patients received CRT with differences in the clinical indications between countries. Conclusion(s) CRT is an important treatment option for eligible patients with HF, which is still largely underused. The findings reported demonstrate that awareness of CRT indications as well as demographics, organizational and economic factors play an important role in CRT utilization.

Author: A Azari, I Kristjansdottir, P Gatti, and F Gadler
Subjects: Physiology (medical), Cardiology and Cardiovascular Medicine
Abstract: Background Risk assessment of TLE patients may be challenging due to incomplete knowledge about possible risk factors for post-TLE outcomes. The aim of this study was to identify predictors of 30-days and 1-year all-cause mortality including the novel parameter frailty in a large retrospective series of patients undergoing TLE at a high-volume centre. Methods Medical journals of 893 consecutive patients undergoing TLE between January 1, 2010 and December 31, 2018 were retrogradely analysed. Univariate logistic regression and multivariate analyses were performed to identify risk factors. Results A total of 893 patients were identified. Local infection was the dominant indication (41.1%) and pacemaker was the most common device (49.4%). Mean age was 65±16 years and 73.0% were males. The median follow up was 3.9 years (IQR, 4.5 years). Within the systemic infection group, Staphylococcus aureus was the main microorganism in the positive blood cultures (44.4%) and 69.4% of the patients had vegetations. The 30-days and 1 year mortality rates were 2.5% and 9.7%, respectively. Per-procedural mortality occurred in 1 patient. Significant risk factors for 30-days all-cause mortality at univariate analysis were anaemia, systemic infection, clinical frailty scales (CFS) 5–7 and stage 5 chronic kidney disease (CKD). Age, CRT-P/D (vs ICD), reduced ejection fraction, anaemia, BMI Conclusions Patient-related characteristics, comorbidities and systemic infection independently predicted worse post-TLE prognosis. Several parameters need to be considered when assessing patients for TLE in order to risk stratify the patients and optimize the post-TLE care. Frailty is a novel parameter with significant influence on short and long-term outcome. Funding Acknowledgement Type of funding sources: Public Institution(s).

Abstract: The use of continuous-infusion in outpatient setting could be widely used in oncology and haematology care. Many times the lack of data stability about single drug or admixture of drugs, together with patient education and safety, make difficult the transition from inpatient to outpatient setting. Nowadays, this is a big challenge for hospital pharmacists, who must take into consideration the critical issues related to chemical and physical stability, besides microbiological one, in order to ensure high quality preparations and guarantee the safety and quality of care, to protect patients and their health. The aim of this article is to highlight the critical issues concerning the transition from inpatient to outpatient setting, with particular interest regarding chemotherapy protocols, which require preparation with long-term continuous-infusion.

Abstract: Introduction Heart failure is a clinical syndrome in which signs and symptoms are due to functional and/or structural abnormalities of the heart which prevent the necessary supply of oxygenated blood or do so at the expense of high filling pressures. It has a prevalence of 1–2% in the western world and increasing prevalence with increasing age. While the prognosis for coronary heart disease has improved significantly, the same does not apply for heart failure, perhaps because some effective treatment methods have not been sufficiently implemented in health care. One effective but underutilized heart failure treatment is the cardiac resynchronisation therapy (CRT), that coordinates the contraction of the left and right ventricles via a pacemaker (PM). CRT treatment is an evidence based treatment recommended by among other the ESC guidelines for heart failure. Clinical studies have suggested decreases in mortality, hospitalization, morbidity and improvements in quality of life for heart failure patients receiving a CRT. Purpose To find a new clinical pathway to improve CRT implementation and to evaluate if it might be optimized through ECG-based surveillance and thus improving prognosis. Methods In a population of approximately 2.5 million people in our region we investigated the University Hospital's ECG database between 2000 and 2018. During which time 432 108 adult patients with 1 482 489 ECG's presented to the hospital. We searched and found 5 511 unique patients with the following ECG criteria: QRS ≥150 ms at any time, LBBB and Non pace. According to the Pacemaker Registry we excluded 771 patients that had previously received a PM/CRT. We also identified patients with diagnosis of heart failure by using the ICD-10 codes (I42.0 and I50). Results Our final cohort consists of 4 740 patients. The median age was 75 (19–112) years, 34.5% were female and 14.9% were subsequently implanted with a CRT (60% with CRT-D). The median time to CRT implantation from the first ECG with LBBB was 244 (IQR 994) days. Of the 4 740 patients 20.6% had a previous hospitalistion for heart failure with a median delay from the hospitalisation to CRT implantation of 5 (IQR 5.4) years. Conclusions Our observational data from a large real-life regional ECG database show there is a considerable number of heart failure patients that could benefit from CRT treatment. Using an existing ECG database could be useful in finding patients with indication for CRT implantation. This could possibly influence morbidity and mortality in a regional heart failure population by minimizing the delay of CRT treatment.

Abstract: Introduction Complete atrioventricular block (CAVB), either congenital or post heart surgery, are the main indications for cardiac pacing in the pediatric population. Epicardial pacing is preferred in small infants or for specific cardiac anomalies and some studies highlight a superior contraction pattern when pacing epicardially from the left ventricular apex region [1–3]. Endocardial pacing is more frequently used in children with a weight >20 kg and is less invasive [4]. Paced QRS duration seems to be independently associated with ventricular dysfunction irrespective of location or age at device implantation [5]. Purpose Describe the echocardiographic and electrocardiographic changes after switch from epicardial to transvenous pacing in a pediatric population with CAVB. Methods Children (0–18 years), who underwent a switch from left- (LV) or right ventricle (RV) epicardial pacing to transvenous pacing at our center, were retrospectively studied. Clinical, ECG- and echocardiographic parameters before and after the switch of the PM-system were collected as well as the most recent FU data. Left ventricular end-diastolic diameter (LVDD) and fractional shortening (FS) values were transformed to a body surface-related and age-related z-score (z), respectively. Results Fifteen patients with CAVB who received an epicardial pacemaker (60% congenital, 40% post-cardiac surgery) were converted to a transvenous system at our center (2005–2021). The median age at the switch was 6.8 (2–13) years with a median weight of 21 (9–62) kg. The epicardial lead location was more frequently the RV wall (60%) than the LV wall (40%). The RV outflow tract and interventricular septum were the most common locations (73%) for the endocardial leads. The mean QRS duration during epicardial stimulation was 150 (IQR 26) ms vs. a median QRS duration with the transvenous system of 136 (IQR 19) ms and a median delta QRS duration of 13ms. A detailed comparison between RV and LV epicardial pacing are reported in Figure 1. Children with post-surgical AV block had a broader median QRS duration, both with epicardial and endocardial stimulation. Before the switch, there was only one abnormal observation of FS less than −2 z with normal LVDD. At the last available follow-up (mean time 7 years), all the children had normal LVDD and only one had FS less than −2 z. Conclusions Our report of pediatric patients after switch from epi to endo pacing, shows good results in terms of QRS duration with no significant echocardiographic or clinical evidence of deterioration of the cardiac function. Due to the small sample size the results could serve as a hypothesis generator, but larger prospective studies are needed to evaluate the electrocardiographic and echocardiographic impact of transvenous - compared to epicardial pacing.

Abstract: Anchovy Engraulis encrasicolus distribution in European waters spans from the Mediterranean Sea to the North Sea, and is expected to expand further north with global warming. Observations from the eastern Mediterranean (North Aegean Sea), the Bay of Biscay and the North Sea reveal latitudinal differences in growth, maximum size, fecundity and timing of reproduction. We set up a mechanistic framework combining a bioenergetics model with regional physical-biogeochemical models providing temperature and zooplankton biomass to investigate the underlying mechanisms of variation in these traits. The bioenergetics model, based on the Dynamic Energy Budget theory and initially calibrated in the Bay of Biscay, was used to simulate growth and reproduction patterns. Environment partly explained the increased growth rate and larger body size towards the north. However, regional calibration of the maximum assimilation rate was necessary to obtain the best model fit. This suggests a genetic adaptation, with a pattern of cogradient variation with increasing resource towards the north, in addition to a countergradient thermal adaptation. Overall, the seasonal energy dynamics supports the pattern of body-size scaling with latitude, i.e. food-limited growth but low maintenance costs in the warm Aegean Sea, and larger size in the North Sea allowing sufficient storage capacity for overwintering. Further, the model suggests a synchronisation of reproductive timing with environmental seasonality as a trade-off between thresholds of temperature and reserves for spawning and overwintering, respectively. Finally, low temperature, short productive and spawning seasons, and insufficient reserves for overwintering appear to be current limitations for an expansion of anchovy to the Norwegian Sea.

Abstract: BackgroundSevere acute respiratory syndrome coronavirus-2 is a formidable virus, responsible for coronavirus disease 2019 and endowed with marked neurotropism. The damage it causes to the nervous system is manifold. The main neurological manifestation is anosmia. Olfactory damage is often transient, but there are no data reflecting an observational period of several months.ObjectiveThis study evaluated the trend of anosmia in patients affected by coronavirus disease 2019 in the eight months following diagnosis.MethodsFifty-five subjects who presented with symptoms suggestive of coronavirus disease 2019 and who developed anosmia, between the end of February and the beginning of March 2020, were investigated. The patients were interviewed after eight months to determine functional recovery and assess the degree of recovery.ResultsNinety-one per cent of the population reported olfactory recovery and, of these, 53 per cent had total recovery after eight months. Females and younger age groups seem slightly advantaged in functional recovery. The elderly population appears to have excellent prospects for full functional recovery.ConclusionAnosmia represents a frequent neurological manifestation during coronavirus disease 2019. Fortunately, it is transient in most cases, and only a small percentage of patients affected by it report long-term functional deficits.

Abstract: The Xingu River, one of the most important of the Amazon Basin, is characterized by clear and transparent waters that drain a 509.685 km2 watershed with distinct hydrological and ecological conditions and anthropogenic pressures along its course. As in other basins of the Amazon system, studies in the Xingu are scarce. Furthermore, the eminent construction of the Belo Monte for hydropower production, which will alter the environmental conditions in the basin in its lower middle portion, denotes high importance of studies that generate relevant information that may subsidize a more balanced and equitable development in the Amazon region. Thus, the aim of this study was to analyze the water quality in the Xingu River and its tributaries focusing on spatial patterns by the use of multivariate statistical techniques, identifying which water quality parameters were more important for the environmental changes in the watershed. Data sampling were carried out during two complete hydrological cycles in twenty-five sampling stations. The data of twenty seven variables were analyzed by Spearman's correlation coefficients, cluster analysis (CA), and principal component analysis (PCA). The results showed a high auto-correlation between variables (> 0.7). These variables were removed from multivariate analyzes because they provided redundant information about the environment. The CA resulted in the formation of six clusters, which were clearly observed in the PCA and were characterized by different water quality. The statistical results allowed to identify a high spatial variation in the water quality, which were related to specific features of the environment, different uses, influences of anthropogenic activities and geochemical characteristics of the drained basins. It was also demonstrated that most of the sampling stations in the Xingu River basin showed good water quality, due to the absence of local impacts and high power of depuration of the river itself.

Abstract: We report a measurement of the strong coupling constant, ${\ensuremath{\alpha}}_{s}({M}_{Z})$, extracted from inclusive jet production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1800\mathrm{GeV}$. The QCD prediction for the evolution of ${\ensuremath{\alpha}}_{s}$ with jet transverse energy ${E}_{T}$ is tested over the range $40l{E}_{T}l450\mathrm{GeV}$ using ${E}_{T}$ for the renormalization scale. The data show good agreement with QCD in the region below 250 GeV. The value of ${\ensuremath{\alpha}}_{s}$ at the mass of the ${Z}^{0}$ boson averaged over the range $40l{E}_{T}l250\mathrm{GeV}$ is found to be ${\ensuremath{\alpha}}_{s}({M}_{Z})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.1178\ifmmode\pm\else\textpm\fi{}0.0001(\mathrm{stat}{)}_{\ensuremath{-}0.0095}^{+0.0081}(\mathrm{expt}.\mathrm{syst})$. The associated theoretical uncertainties are mainly due to the choice of renormalization scale $({+6%}{\ensuremath{-}4%})$ and input parton distribution functions $(5%)$.

Abstract: The wear resistance of Zn-Al alloys is determined in pin-on-ring wear tests, as a function of type of structure of the as-cast alloys. Three regions were observed; columnar, equiaxed and columnar-to-equiaxed grain transition. The results show that the equiaxed structure is the most resistant. In addition, the relation between wear rate and grain size depends on type of structure and it is more pronounced for the equiaxed structure. The effect is almost negligible for the columnar grain structure. Fil: Rosenberger, Mario Roberto. Universidad Nacional de Misiones; Argentina.

Abstract: Reconstruction after circumferential pharyngolaryngectomy is a challenging problem. Reconstruction methods should ensure an appropriate mucosa lining of the digestive tract, preferably already tubulized, and peristalsis. Despite the high reported success rates, the jejunum flap is still occasionally lost due to thrombosis of the pedicle and/or fistula formation. Five cases of circumferential pharyngolaryngectomy in which failure of the jejunum loop was managed with a second free or pedicle flap are presented. A second free jejunum was reliable in selected patients, depending on time of detection of flap necrosis, on bacterial control of the wound and on the vascular or general conditions. For this reason, careful monitoring of the flap and clinical signs of necrosis in the first 5 post-operative days is crucial to prevent the formation of fistulas and infection and to increase the possibility of using this kind of salvage surgery. Pedicle flaps should be used only in the event of severe complications because of their high risk of post-operative salivary fistulas.

Abstract: The ideal reconstruction after circumferential pharyngolaryngectomy is represented by the jejunum free flap, but when the resection extends to the oro- or nasopharynx, the discrepancy between the lumen of the flap and the pharyngeal defect represents a disadvantage. Two reconstructions to overcome this problem are presented: end-to-side anastomosis between the pharynx and the antimesenteric side of the jejunum; and a jejunal "reservoir." The type 1 technique is quicker to perform, but can result in dysphagia; the type 2 technique is more complex, but usually no dysphagia is observed. In our opinion, no ideal surgical technique exists to equal the jejunum loop. The choice must be tailored to the single patient, bearing in mind the degree of the defect, the stage of the tumor removed, the general conditions of the patient, and personal surgical experience. Whatever procedure is chosen, it should provide the best possible quality of life for the expected life span of the patient.

17. The design of the modern urban environment of Rovereto, Italy: the valorisation of modern architecture

Abstract: Modern society is increasingly demanding sustainability from its towns and cities, urban landscapes and building complexes. Developments now have to respect the environment, guarantee efficient and comfortable living conditions and adopt the best strategies, technologies and materials the market has to offer. Many groups of buildings from the past have these characteristics and their validity necessitates careful preservation and valorisation. After a period of apparent indifference, valorisation has also begun for early 20th century architecture, considered formally, functionally and technologically sustainable. Its continued ability to satisfy all needs has prevented it from being altered, while maintenance on the other hand has been constant, preventing the onset of functional and physical obsolescence. In particular, modern architecture from the early 1900s in general demonstrates that buildings correctly satisfying urban, architectural and technological parameters do not need specific preservation and valorisation policies. They are preserved thanks to their quality and the simple passage of time is enough to ensure their valorisation, transforming them into “designer architecture”, even when created by anonymous architects. An analysis was therefore carried out of buildings constructed between 1904 and 1915 by an unknown civic engineer, Ettore Gilberti, in the small provincial city of Rovereto, part of the AustroHungarian Empire. Ettore Gilberti was responsible for defining housing with innovative layout and technology, adopting planning and economic criteria still widely applicable to construct new parts of the city even today.

Abstract: The last century’s urban-development objective is no longer pertinent. Yet the cities must continue to grow, but, above all, the quality of life of its inhabitants must be improved by reducing the ecological footprint, which in many cases is unsustainable. In the on-going search for guidelines and strategic intervention, the need for the re-densification and the restoration/completion of a degraded urban fabric has emerged at various levels. The restoration of existing heritage and the building densification are fundamental actions for urban enhancement and requalification whose raison d’etre is the reduction in land consumption. An INA Casa residential district built in 1958 in Trento comprising a series of buildings, with a variety of floor areas, has been analysed from this standpoint. It has emerged that, notwithstanding design proposals that would have made the district fully functional, some indispensible infrastructures were never built. The analysis of the district has produced a qualitative cognitive map that addresses areas of intervention (from the technological and structural to environmental design).

Abstract: Food web dynamics consist of processes that affect ecosystem structure and functioning. EcoTroph (ET) is a recently developed approach and software for modeling aquatic ecosystems, articulated entirely around the trophic level concept. Here, we used ET to investigate impacts of 2 trophic controls (i.e. foraging arena and top-down controls) on marine ecosystem trophic flows and associated fishing effects. A new version of the ET model accounting for the foraging arena theory was developed. Cross impacts of the 2 trophic controls and different fishing scenarios were analyzed using a virtual ecosystem. Results showed that foraging arena controls decreased the resistance and production of an ecosystem facing increasing fishing mortality. In contrast, the inclusion of top-down controls resulted in a more resistant ecosystem, with a decrease in the kinetics of trophic flows at lower trophic levels (TLs) when the abundance of higher TLs is reduced by fishing. These 2 controls increased the interactions between TLs, and, in part, shaped fishing impacts at the ecosystem scale. Then, we applied ET to 3 real ecosystems which have been previously modeled using Ecopath with Ecosim (EwE). EcoTroph and Ecosim predictions related to changes in fishing effort were compared, and showed that accounting for trophic controls enabled EcoTroph to mimic Ecosim models, and better reflect associated changes in trophic flows. The 3 case studies exhibited different behaviors: while the pelagic ecosystem had strong foraging arena controls but no top-down controls, the other ecosystems were characterized by weaker foraging arena controls but effective top-down controls.

Abstract: Tourism is characterized by noteworthy changes regarding both the demand and the innovations in the services aimed to make the tourist experience more and more fulfilling and sustainable. Today, tourists are interested in living the journey also as an opportunity to catch the cultural and social aspects of a place. Summer pastures (“alpeggi”) and seasonal alpine farmsteads (“malghe”) are important spaces for tourism, but these are fundamental components of the economy, the society and the culture of the alpine landscape. In this context, leading new congruent principles to the re-use and refunctionalisation of summer farmsteads (“malghe”), alpine huts (“baita”) and all other seasonal production structures must be identified, in an attempt to valorise both traditional aspects and the innovative potentials of participated or nature tourism, able to guarantee the right environmental and economic sustainability.

Abstract: Recovery issues and typological and technological issues appear intrinsically connected on both conceptual and operational level and, as far as non-monumental “civilian” historic buildings are concerned, have been the subject of research for some time. However, publications on non-monumental “military” type historical buildings are less frequent. This undoubtedly derives from the understandable reserve surrounding the construction of groups of building and other structures for the armed forces. These nevertheless represent a vast heritage to be re-introduced onto a circuit of “civilian” use, given the reconfiguration of defence models and consequent abandonment of a large number of structures. The military complexes and single buildings constructed from the end of the 19th century are located in both natural settings and the urban fabric, where they now occupy central positions and therefore make an extremely attractive proposition for restoration and re-functionalization. What documentary historical value in terms of typology and construction technique can be attributed to this particular type of military building? What problems and strategies can be studied to re-introduce them correctly onto the circuit of use? We will try and answer these questions by analysing the military structures in the city of Trento, built by first the Hapsburgs, then the Italian governments and now largely abandoned.

Abstract: We present the results of a search for neutral Higgs bosons produced in association with b quarks in pp-->bb(phi)-->bbb final states with 91+/-7 pb(-1) of pp collisions at sqrt[s] = 1.8 TeV recorded by the Collider Detector at Fermilab. We find no evidence of such a signal and the data are interpreted in the context of the neutral Higgs sector of the minimal supersymmetric extension of the standard model. With basic parameter choices for the supersymmetric scale and the stop-quark mixing, we derive 95% C.L. lower mass limits for neutral Higgs bosons for tan(beta) values in excess of 35.

Abstract: We have measured the ratio of prompt production rates of the charmonium states {chi}{sub c1} and {chi}{sub c2} in 110 pb{sup -1} of p{ovr p} collisions at sqrt[s] = 1.8 TeV. The photon from their decay into J/{psi}{gamma} is reconstructed through conversion into e{sup +}e{sup -} pairs. The energy resolution this technique provides makes the resolution of the two states possible. We find the ratio of production cross sections {sigma}{sub {chi}{sub c2}}/{sigma}{sub {chi}{sub c1}} = 0.96{+-}0.27(stat){+-}0.11(syst) for events with p{sub {tau}}(J/{psi})>4.0 GeV/c, |{eta}(J/{psi})| 1.0 GeV/c.

Abstract: We present the first measurement of the ratio of branching fractions R equivalent to B(t --> Wb)/B(t --> Wq) from pa collisions at roots = 1.8 TeV. The data set corresponds to 109 pb(-1) of data recorded by the Collider Detector at Fermilab during the 1992-95 Tevatron run. We measure R = 0.94(-0.24)(+0.31)(stat + syst) or R > 0.61 (0.56) at 90% (95)% C.L., in agreement with the standard model predictions. This measurement yields a limit on the Cabibbo-Kobayashi-Maskawa quark mixing matrix element \V-tb\ under the assumption of three generations and unitarity.

Abstract: An angular analysis of B{sup 0}{yields}J/{psi}K*{sup 0} and B{sup 0}{sub s}{yields}J/{psi}{phi} has been used to determine the decay amplitudes with parity-even longitudinal (A{sub 0}) and transverse (A{sub {parallel}}) polarization and parity-odd transverse (A{sub {perpendicular}}) polarization. The measurements are based on 190 B{sup 0} and 40 B{sup 0}{sub s} candidates obtained from 89 pb{sup -1} of p{ovr p} collisions at the Fermilab Tevatron. The longitudinal decay amplitude dominates with |A{sub 0}|{sup 2} = 0.59{+-}0.06{+-}0.01 for B{sup 0} and |A{sub 0}|{sup 2} = 0.61{+-}0.14{+-}0.02 for B{sup 0}{sub s} decays. The parity-odd amplitude is found to be small with |A{sub {perpendicular}}|{sup 2} = 0.13{sub -0.09}{sup +0.12}{+-}0.06 for B{sup 0} and |A{sub {perpendicular}}|{sup 2} = 0.23{+-}0.19{+-}0.04 for B{sup 0}{sub s} decays.

Abstract: This Letter describes a direct measurement of the W boson total decay width, {Gamma}{sub W}, using the Collider Detector at Fermilab. The measurement uses an integrated luminosity of 90 pb{sup -1}, collected during the 1994-1995 run of the Fermilab Tevatron p{anti p} collider. The width is determined by normalizing predicted signal and background distributions to 49 844 W {yields}e{nu} candidates and 21 806 W{yields}{mu}{nu} candidates in the transverse-mass region M{sub T}

Abstract: We have measured the polarization of J/psi and psi(2S) mesons produced in pp collisions at sqrt[s] = 1.8 TeV, using data collected at the Collider Detector at Fermilab during 1992-1995. The polarization of promptly produced J/psi [psi(2S)] mesons is isolated from those produced in B-hadron decay, and measured over the kinematic range 4 [5.5]

Abstract: We report the results of a search for second and third generation leptoquarks using 88 pb{sup -1} of data recorded by the Collider Detector at Fermilab. Color triplet technipions, which play the role of scalar leptoquarks, are investigated due to their potential production in decays of strongly coupled color octet technirhos. Events with a signature of two heavy flavor jets and missing energy may indicate the decay of a second (third) generation leptoquark to a charm (bottom) quark and a neutrino. As the data are found to be consistent with standard model expectations, mass limits are determined.

Abstract: We use 106 pb{sup -1} of data collected with the Collider Detector at Fermilab to search for narrow-width, vector particles decaying to a top and an antitop quark. Model independent upper limits on the cross section for narrow, vector resonances decaying to t{ovr t} are presented. At the 95% confidence level, we exclude the existence of a leptophobic Z' boson in a model of top-color-assisted technicolor with mass M{sub Z'}

Abstract: Events collected by the Collider Detector at Fermilab (CDF) with an energetic jet plus large missing transverse energy can be used to search for physics beyond the standard model. We see no deviations from the expected backgrounds and set upper limits on the production of new processes. We consider in addition the production of light gravitinos and set a limit at 95% confidence level on the breaking scale root F greater than or equal to 217 GeV, which excludes gravitino masses smaller than 1.1 X 10(-5) eV/c(2).

Abstract: We have searched for direct pair production of scalar top and scalar bottom quarks in 88 pb-1 of pp collisions at sqrt[s]=1.8 TeV with the CDF detector. We looked for events with a pair of heavy flavor jets and missing energy, consistent with scalar top (bottom) quark decays to a charm (bottom) quark and a neutralino. The numbers of events that pass our selections show no significant deviation from standard model expectations. We compare our results to the next-to-leading order scalar quark production cross sections to exclude regions in scalar quark-neutralino mass parameter space.

Abstract: We have searched for direct production of scalar top quarks at the Collider Detector at Fermilab in 88 pb{sup -1} of pp collisions at {radical}(s)=1.8 TeV . We assume the scalar top quark decays into either a bottom quark and a chargino or a bottom quark, a lepton, and a scalar neutrino. The event signature for both decay scenarios is a lepton, missing transverse energy, and at least two b -quark jets. For a chargino mass of 90 GeV/c{sup 2} and scalar neutrino masses of at least 40 GeV/c{sup 2} , we find no evidence for scalar top production and present upper limits on the production cross section in both decay scenarios.

Abstract: We have reconstructed the radiative decays chi(b)(1P)-->Upsilon(1S)gamma and chi(b)(2P)-->Upsilon(1S)gamma in pp collisions at sqrt[s] = 1.8 TeV, and measured the fraction of Upsilon(1S) mesons that originate from these decays. For Upsilon(1S) mesons with p(Upsilon)(T)>8.0 GeV/c, the fractions that come from chi(b)(1P) and chi(b)(2P) decays are [27.1+/-6.9(stat)+/-4. 4(syst)]% and [10.5+/-4.4(stat)+/-1.4(syst)]%, respectively. We have derived the fraction of directly produced Upsilon(1S) mesons to be [50.9+/-8.2(stat)+/-9.0(syst)]%.

Abstract: We have studied the production of B hadrons in 1.8-TeV pp(bar sign) collisions. We present measurements of the fragmentation fractions, f{sub u} , f{sub d} , f{sub s} , and f{sub baryon} , of produced b quarks that yield B{sup +} , B{sup 0} , B{sup 0}{sub s} , and {lambda}{sup 0}{sub b} hadrons. Reconstruction of five electron-charm final states yields f{sub s}/( f{sub u}+f{sub d})=0.213{+-}0.068 and f{sub baryon}/( f{sub u}+f{sub d})=0.118{+-}0.042 , assuming f{sub u}=f{sub d} . If all B hadrons produced in pp(bar sign) collisions cascade to one of these four hadrons, we determine f{sub u}=f{sub d}=0.375{+-}0.023 , f{sub s}=0.160{+-}0.044 , and f{sub baryon}=0.090{+-}0.029 . If we do not assume f{sub u}=f{sub d} , we find f{sub d}/f{sub u}=0.84{+-}0.16 . (c) 2000 The American Physical Society.

Abstract: We search for color singlet technirho and technipion production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\phantom{\rule{0ex}{0ex}}\mathrm{TeV}$ recorded with the Collider Detector at Fermilab. These exotic technimesons are present in a model of walking technicolor. The signatures studied are lepton plus two jets plus ${E}_{T}$ and multijet final states. No excess of events is seen in either final state. We set an upper limit on the technirho production cross section and exclude a region in the technipion mass versus technirho mass plane.

Abstract: We present the results of a search for pair production of a fourth-generation charge -1 / 3 quark (b(')) in sqrt[s] = 1.8 TeV pp collisions using 88 pb(-1) of data obtained with the Collider Detector at Fermilab. We assume that both quarks decay via the flavor-changing neutral current process b(')-->bZ(0) and that the b(') mass is greater than m(Z)+m(b). We studied the decay mode b(')b(');-->Z(0)Z(0)bb where one Z0 decays into e(+)e(-) or m(+)m(-) and the other decays hadronically, giving a signature of two leptons plus jets. An upper limit on the sigma(pp-->b(')b(');)x[B(b(')-->bZ(0))](2) is established as a function of the b(') mass. We exclude at 95% confidence level a b(') quark with mass between 100 and 199 GeV/c(2) for B(b(')-->bZ(0)) = 100%.

Abstract: We update the measurement of the t (t) over bar production cross section using the CDF detector at the Fermilab Tevatron. This measurement uses t (t) over bar decays to the final states e + nu + jets and mu + nu + jets. We search for b quarks from t decays via secondary-vertex identification or the identification of semileptonic decays of the b and cascade c quarks. The background to the t (t) over bar production is determined primarily through a Monte Carlo simulation. However, we calibrate the simulation and evaluate its uncertainty using several independent data samples. For a top quark mass of 175 GeV/c(2), we measure sigma (t (t) over bar)-=5.1 +/- 1.5 pb and sigma (t (t) over bar)=9.2 +/- 4.3 pb using the secondary vertex and the lepton tagging algorithms, respectively. Finally, we combine these results with those from other t (t) over bar decay channels and obtain sigma (t (t) over bar)-= 6.5 (+1.7)(-1.4)pb.

Abstract: We present the results of a search for pair production of scalar top quarks ([Formula presented]) in an [Formula presented]-parity violating supersymmetry scenario in [Formula presented] of [Formula presented] collisions at [Formula presented] collected by the Collider Detector at Fermilab. In this mode each [Formula presented] decays into a [Formula presented] lepton and a [Formula presented] quark. We search for events with two [Formula presented]’s, one decaying leptonically ([Formula presented] or [Formula presented]) and one decaying hadronically, and two jets. No candidate events pass our final selection criteria. We set a 95% confidence level lower limit on the [Formula presented] mass at [Formula presented] for [Formula presented]

45. Palladium-catalysed enantiodivergent synthesis of cis- and trans-4-aminocyclohex-2-enols

Abstract: Enantiomerically pure cis- and trans-4-aminocyclohex-2-enols are prepared from cyclohexa-1,3-diene via (-)-cis-(1R,4S )-4-acetoxycyclohex-2-enol (-)-2a using palladium(0) chemistry. Benzylamine and diethylamine are tested in the Pd0-catalysed allylic amination reactions. Since acetate is too slow as a leaving group and gave considerable amounts of side products, a number of leaving groups have been investigated. Of these phosphinate and 2,4-dichlorobenzoate are excellent leaving groups and result in efficient and highly stereoselective reactions; chloride as allylic leaving group also gives good results. By variation of the leaving group and proper choice of the protecting group it is possible to synthesise all four stereoisomers of 4-aminocyclohex-2-enol in good yield and high enantiomeric excess.

Abstract: Chiral cis- and trans-4-aminocyclohex-2-enols and achiral 4-aminocyclohexanols, which all are analogues of ambroxol, are prepared via stereoselective allylic substitution of cyclohex-2-ene-1,4-diol derivatives or 1-acetoxy-4-chlorocyclohex-2-ene. The chiral target molecules are obtained in enantiomerically pure form by employing a previously described enantiodivergent synthesis of cis- and trans-4-aminocyclohex-2-enols. It has been found that bis(amine) nucleophiles 7a and 7b react only at the benzylic amino group under the conditions employed.

Abstract: Palladium-catalyzed 1,4-oxidation of conjugated dienes involving carbon-carbon bond formation has been realized. The reaction is performed with both acyclic and cyclic dienes with a carbon chain containing a terminal or internal triple bond. A vinylpalladium species formed by chloropalladation of the alkyne inserts one of the double bonds of the diene in a Heck-type reaction. The addition of palladium and chloride over the triple bond is non-stereoselective while the overall 1,4-addition by carbon and chloride over the diene is highly stereoselective and occurs anti. The stereoselectivity of the chloropalladation is dependent on the chloride concentration and varies with the substrate.

Abstract: Renal cell carcinoma (RCC) accounts for the 3% of all solid tumors. Despite continuous improvement in the therapy regimen, less has been achieved in terms of enabling an earlier diagnosis: the neoplasia usually reveals its presence at an advanced stage, obviously affecting prognosis. The most frequent sites of secondary disease are shown to be lungs (50–60%), bone (30–40%), liver (30–40%) and brain (5%); while the head and neck district seems to account for less than 1% of patients with primary kidney lesion. We report here the case of a 70-year old man who presented with acute renal failure due to abdominal recurrence of RCC 18 years post nephrectomy. After a few months of follow up without any systemic therapy due to the renal impairment, the patient presented a vascularized tongue lesion that was demonstrated to be a secondary localization of the RCC. This lesion has, therefore, been treated with microsphere embolization to stop the frequent bleeding and to lessen the unbearable concomitant symptoms it caused, such as dysphagia and pain. A tongue lesion that appears in a RCC patient should always be considered suspect and a multidisciplinary study should be conducted both to assess whether it is a metastasis or a primary new lesion and to understand which method should be selected, if necessary, to treat it (surgery, radiation or embolization). Lingual metastasis should be examined accurately not only because they seem to implicate a poor prognosis, but also because they carry a burden of symptoms that not only threatens patients’ lives but also has a strong impact on their quality of life.
