Microstate probabilities as a function of pH generate titration curves that highlight the low energy, observable microstates, which can then be compared with experiment. A network description connecting microstates as nodes makes it straightforward to test thermodynamic consistency of microstate free energies. The utility of this analysis is illustrated by a description of one molecule from the SAMPL6 Blind pKa Prediction Challenge. Analysis of microstate ∆G°s also makes a more compact way to archive and compare the pH dependent behavior of compounds with multiple protonatable sites.Although there is accumulating evidence for the usefulness of imaging-guided percutaneous coronary intervention (PCI), there are few studies for acute coronary syndrome (ACS), and the impact of the frequency of use has not been well addressed. From the Kumamoto Intervention Conference Study; a Japanese registry comprising 17 institutions, consecutive patients undergoing successful PCI from April 2008 through March 2014 were enrolled. Subjects were divided into two groups imaging-guided PCI and angiography-guided PCI. Clinical outcome was a composite of cardiac death, non-fatal myocardial infarction, and stent thrombosis within 1 year. A total of 6025 ACS patients were enrolled 3613 and 2412 patients with imaging- and angiography-guided PCI, respectively. Adverse cardiac events were significantly lower in the imaging-guided PCI group (long-rank P  less then  0.001). Even after propensity-score matching, the event rates still showed significant differences between the two groups (log-rank P = 0.004). To assess the effects of frequency of imaging usage, we divided the 17 institutions into six low-, six moderate-, and five high-frequency groups. The event rates decreased depending on the frequency, seemingly driven by stepwise event suppression in angiography-guided PCI. In Japanese ACS patients, the incidence of adverse clinical events in patients treated with imaging-guided PCI were significantly lower than that in patients with angiography-guided PCI. Better clinical result was found in the institutions using intravascular imaging more frequently. University Hospital Medical Information Network (UMIN)-CTR (http//www.umin.ac.jp/ctr/). Identifier KICS (UMIN000015397).The technical outcome of poor distal vessel quality (PDV) on chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is yet to be clearly elucidated. PDV has not been evaluated in scoring systems. We examined 193 consecutive CTO-PCIs performed in January 2013-December 2017. The endpoint, including the technical outcomes in these patients between with and without PDV, was analyzed. Moreover, we re-evaluated the predictors for CTO-PCI difficulty according to Japan-CTO score. Out of 193 CTO-PCIs, 181 (93.8%) achieved technical success [including 101 (55.8%) with and 80 (44.2%) without PDV]. In patients with and without PDV, the success rates of guidewire crossing using only the antegrade technique were 46.5% vs. 83.8%, respectively (p  less then  0.0001) and using the retrograde approach were 53.5% vs. 16.3%, respectively (p  less then  0.0001). Afuresertib Moreover, there were 56 non-interventional collateral channels in 181 patients. The successful rate of primary antegrade approach was significantly lower and the rate of a rescue retrograde approach was significantly higher with PDV (37.2% vs. 62.8%, 76.9% vs. 23.1%, respectively; p  less then  0.0119). Significant predictors associated with successful guidewire crossings of ≤ 30 min included blunt stump, calcification, bending, occlusion length ≥ 20 mm, retry lesion following Japan-CTO score, and PDV (p  less then  0.05, all). Multivariate analyses demonstrated that blunt stump, calcification, bending, retry lesion, and PDV were independent predictors of unsuccessful guidewire crossing of ≤ 30 min (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.13-0.71, p = 0.0039; OR 0.34, 95% CI 0.16-0.71, p = 0.0035; OR 0.17, 95% CI 0.05-0.60, p = 0.0034; OR 0.18, 95% CI 0.06-0.54, p = 0.0008; and OR 0.19, 95% CI 0.09-0.41, p  less then  0.0001, respectively). PDV could affect the technical outcome of CTO-PCI.Toxicity to fish of multicomponent metal mixtures at maximum-permissible-concentrations (MPC Cd-0.005, Cr-0.01, Cu-0.01, Ni-0.01, Pb-0.005 and Zn-0.1 mg/L) set for EU inland waters was evaluated using the whole-mixture approach. An extended follow-up study on the biological effects of multicomponent metal mixtures on three ecologically different fish species, i.e. Perca fluviatilis, Rutilus rutilus, and Salmo salar is reported. The aim of this study was to assess response patterns of biomarkers (erythrocytic nuclear abnormalities (ENAs), metal accumulation and metallothioneins) in tissues of fish species after 14-day treatment with multicomponent metal mixtures at MPC and metal mixtures with one of its components at reduced MPC (↓). After treatments with Cu↓ and Cr↓, the lowest amount of Ni was found in all tissues (except the liver) of all fish species tested. After Zn↓ and Pb↓ treatments, the amount of Ni in muscle of all the tested fish species significantly decreased. The highest amounts of Cr in gills and Pb in muscle were detected in all fish species after treatments with Ni↓ and Cd↓ mixtures, respectively. R. rutilus accumulated significantly larger amounts of metals than P. fluviatilis and S. salar. The data obtained show that tissues of the omnivorous R. rutilus exposed to metal mixtures accumulated higher amounts of Cr, Cu, Ni and Zn, while tissues of carnivorous S. salar and P. fluviatilis higher amounts of Cd and Pb. The analysis of ENAs revealed concentration-dependent responses, indicating Cu↓ and Cr↓ treatments as causes of higher geno- and cytotoxicity levels.People's parallel-processing ability is limited, as demonstrated by the psychological refractory period (PRP) effect The reaction time to the second stimulus (RT2) increases as the stimulus onset asynchrony (SOA) between two stimuli decreases. Most theoretical models of PRP are independent of modalities. Previous research on PRP mainly focused on vision and audition as input modalities; tactile stimuli have not been fully explored. Research using other paradigms and involving tactile stimuli, however, found that dual-task performance depended on input modalities. This study explored PRP with all the combinations of input modalities. Thirty participants judged the magnitude (small or large) of two stimuli presented in different modalities with an SOA of 75-1,200 ms. PRP effect was observed, i.e., RT2 increased with a decreasing SOA, in all the modalities. Only in the auditory-tactile condition did the accuracy of Task 2 decrease with a decreasing SOA. In the auditory-tactile and tactile-visual conditions, RT to the first stimulus also increased with a decreasing SOA.
