Trans-to-cis isomerization of a platinum(II) complex with two triphosphine ligands via coordination with gold(I) ions

The version of record of this article, first published in Journal of Inclusion Phenomena and Macrocyclic Chemistry, is available online at Publisher’s website: https://doi.org/10.1007/s10847-024-01228-2.The reaction of a square-planar platinum(II) complex containing two bis(2-diphenylphosphinoethyl)phenylphosphine (triphos), [Pt(triphos)2](NO3)2, with [Au(tu)2]Cl (tu = thiourea) gave a new trinuclear AuI2PtII complex, [Pt(triphos)2{Au(tu)}2]Cl2(NO3)2, through Au-P coordination. While the [Pt(triphos)2]2+ unit in [Pt(triphos)2](NO3)2 adopted the trans-meso configuration, only the cis-racemic isomer was observed for [Pt(triphos)2{Au(tu)}2]Cl2(NO3)2. 31P NMR spectroscopy indicated rapid equilibrium among the possible isomers of [Pt(triphos)2]2+, which facilitated the trans-to-cis transformation at the PtII center in this system. Additionally, we observed that this structural transformation led to an increase in the emission intensity

Sarcopenia, intramuscular fat deposition, and visceral adiposity independently predict the outcomes of hepatocellular carcinoma

Background & AimsObesity defined by body mass index (BMI) significantly increases the risk of hepatocellular carcinoma (HCC). In contrast, not only obesity but also underweight is associated with poor prognosis in patients with HCC. Differences in body composition rather than BMI were suggested to be true determinants of prognosis. However, this hypothesis has not been demonstrated conclusively.MethodsWe measured skeletal muscle index (SMI), mean muscle attenuation (MA), visceral adipose tissue index, subcutaneous adipose tissue index, and visceral to subcutaneous adipose tissue area ratios (VSR) via computed tomography in a large-scale retrospective cohort of 1257 patients with different stages of HCC, and comprehensively analyzed the impact of body composition on the prognoses.ResultsAmong five body composition components, low SMI (called sarcopenia), low MA (called intramuscular fat [IMF] deposition), and high VSR (called visceral adiposity) were significantly associated with mortality, independently of cancer stage or Child-Pugh class. A multivariate analysis revealed that sarcopenia (hazard ratio [HR], 1.52; 95% confidence interval [CI], 1.18–1.96; p=0.001), IMF deposition (HR, 1.34; 95% CI, 1.05–1.71; p=0.020), and visceral adiposity (HR, 1.35; 95% CI, 1.09–1.66; p=0.005) but not BMI were significant predictors of survival. The prevalence of poor prognostic body composition components was significantly higher in underweight and obese patients than in normal weight patients.ConclusionsSarcopenia, IMF deposition, and visceral adiposity independently predict mortality in patients with HCC. Body composition rather than BMI is a major determinant of prognosis in patients with HCC

Research and Development for Near Detector Systems Towards Long Term Evolution of Ultra-precise Long-baseline Neutrino Experiments

With the discovery of non-zero value of $\theta_{13}$ mixing angle, the next generation of long-baseline neutrino (LBN) experiments offers the possibility of obtaining statistically significant samples of muon and electron neutrinos and anti-neutrinos with large oscillation effects. In this document we intend to highlight the importance of Near Detector facilities in LBN experiments to both constrain the systematic uncertainties affecting oscillation analyses but also to perform, thanks to their close location, measurements of broad benefit for LBN physics goals. A strong European contribution to these efforts is possible

Status of the Super-Kamiokande and the K2K experiment

In this paper, the recent results of atmospheric neutrino oscillation analysis and the current status of the Super-Kamiokande are presented. This time, entire SK-I data, which correspond to the 1489 days live days, were analyzed and the preliminary results of the oscillation analysis are reported. Also, the recent results and current status of the KEK to Kamioka long-baseline neutrino oscillation (K2K) experiment are presented. PACS: 14.60.pq Neutrino oscillation

Atmospheric Neutrino Results from Super-Kamiokande

<p>The Super-Kamiokande experiment started its operation in 1996 and accumulated atmospheric neutrino events over the last 20 years. We have performed the determinations of neutrino oscillation mixing parameters, a study on mass hierarchy and leptonic CP violation together with the study of tau neutrinos using the data. In this talk, we will report the new results using the atmospheric neutrino sammples and future prospects.</p
