Zeolites with isolated-framework and oligomeric-extraframework hafnium species characterized with pair distribution function analysis.

Zeolites containing framework heteroatoms (e.g., Ti, Sn, and Hf) with open coordination sites behave as solid-state Lewis acids and exhibit remarkable catalytic properties unachievable with bulk oxides. However, direct evidence confirming the incorporation of such heteroatom species into the zeolite framework is difficult to obtain because of the limited number of analytical methods capable of discerning framework incorporation from extraframework species. In this work, the structural environments of hafnium (Hf) framework and extraframework species added post-synthetically into *BEA zeolites were analyzed using coupled pair distribution function (PDF) and diffuse reflectance (DR) UV-vis measurements. PDF analysis enabled the visualization and identification of framework and extraframework HfOx species, both of which were undetectable by traditional X-ray and neutron diffraction methods. Reactivity data from the aldol condensation of benzaldehyde and acetone confirmed that framework Hf species are responsible for catalytic activity.

Concerted Bimetallic Nanocluster Synthesis and Encapsulation via Induced Zeolite Framework Demetallation for Shape and Substrate Selective Heterogeneous Catalysis.

Bimetallic nanoparticle encapsulation in microporous zeolite crystals is a promising route for producing catalysts with unprecedented reaction selectivities. Herein, a novel synthetic approach was developed to produce PtZnx nanoclusters encapsulated inside zeolite micropores by introducing Pt2+ cations into a zincosilicate framework via ion exchange, and subsequent controlled demetallation and alloying with framework Zn. The resulting zeolites featured nanoclusters with sizes of approximately 1 nm, having an interatomic structure corresponding to a PtZnx alloy as confirmed by pair distribution function (PDF) analysis. These materials featured simultaneous shape and substrate specificity demonstrated by the selective production of p-chloroaniline from the competitive hydrogenation of p-chloronitrobenzene and 1,3-dimethyl-5-nitrobenzene.

Adsorptive Depletion of Myeloid Lineage Leucocytes as Remission Induction Therapy in Patients with Ulcerative Colitis after Failure of First-Line Medications: Results from a Three-Year Real World, Clinical Practice.

BACKGROUND/AIMS: In patients with active ulcerative colitis (UC), pharmacologics, although initially effective in most patients, are associated with refractoriness, loss of response or unfavourable side effects as additional morbidity factors. Depletion of myeloid lineage leucocytes like the CD14(+)CD16(+) monocyte phenotype, which is a major source of tumour necrosis factor-α, by granulocyte/monocyte apheresis (GMA) if effective, is also known to be free from side effects. METHODS: In clinical practice setting, 77 consecutive patients with moderate to severe UC, who failed to respond to first-line medications received GMA with the Adacolumn as remission induction therapy. Patients who achieved remission were followed for 3 years. RESULTS: Among the 77 patients, 46.8% were corticosteroids-naïve, 26% corticosteroid-dependent and 27.3% corticosteroid-refractory. The overall clinical remission rate was 79.2%, and the overall mucosal healing (MH) rate according to the Mayo endoscopic subscore ≤1 was 58.5%. MH rates in corticosteroid-naïve, corticosteroid-dependent and corticosteroid-refractory subgroups were 70.8, 56.3, and 38.5%, respectively. The 3-year sustained clinical remission rates in corticosteroid-naïve, corticosteroid-dependent and corticosteroid-refractory subgroups were 83.3, 68.8, and 23.1%, respectively. CONCLUSION: Corticosteroid-naïve patients appeared to benefit the most from the Adacolumn GMA, and attain a favourable long-term clinical course. Accordingly, GMA should be a first-line therapy in this clinical setting.

An Increased Serum N-Terminal Telopeptide of Type I Collagen, a Biochemical Marker of Increased Bone Resorption, Is Associated with Infliximab Therapy in Patients with Crohn's Disease.

BACKGROUND: Osteopenia and osteoporosis are considered to be extra-intestinal manifestations of inflammatory bowel disease (IBD). Anti-tumor necrosis factor (TNF)-α biologics have been introduced as novel medications for an active IBD. However, it is still not well documented whether anti-TNF-α affects the frequency of bone loss or abnormality of bone mineral markers among patients with IBD. AIMS: This study was to investigate the biochemical basis of low bone mineral density (BMD) and increased turnover in IBD during infliximab (IFX) therapy. METHODS: Forty patients with Crohn's disease (CD), 80 patients with ulcerative colitis (UC), and 65 age- and gender-matched controls were included. BMD was measured with dual-energy X-ray absorptiometry, and vitamins K and D were measured as serum undercarboxylated osteocalcin (ucOC) and 1,25-(OH)2D, respectively. Bone formation and resorption were based on measuring bone-specific alkaline phosphatase (BAP) and serum N-terminal telopeptide of type I collagen (NTx), respectively. RESULTS: Significantly lower BMD was found in patients with UC and CD as compared to controls (P < 0.05). BAP, 1,25-(OH)2D, ucOC, and NTx were significantly higher in CD patients, but not in UC patients as compared to controls (P < 0.05). Further, serum NTx level was significantly higher in CD patients who were receiving IFX as compared to CD patients who were not receiving IFX (P < 0.01). CONCLUSIONS: A lower BMD and higher bone metabolism markers were found in CD patients as compared to controls or UC patients. A significant increased serum level of NTx, a biochemical marker of increased bone resorption, was observed in CD patients during IFX therapy.

Structure-Directing Behaviors of Tetraethylammonium Cations toward Zeolite Beta Revealed by the Evolution of Aluminosilicate Species Formed during the Crystallization Process.

Organic structure-directing agents (OSDAs) have been widely used for the synthesis of zeolites. In most cases, OSDAs are occluded in zeolites as an isolated cation or molecule geometrically fitted within the zeolite cavities. This is not the case for zeolite beta synthesized by using tetraethylammonium (TEA(+)) cation as an OSDA, in which a cluster/aggregate of ca. six TEA(+) cations is occluded intact in the cavity (i.e., the channel intersection) of zeolite beta. The structure direction of TEA(+) in such a nontypical, clustered mode has remained elusive. Here, zeolite beta was hydrothermally synthesized using TEA(+) in the absence of other alkali metal cations in order to focus on the structure-directing behaviors of TEA(+) alone. The solid products formed throughout the hydrothermal synthesis were analyzed by an array of characterization techniques including argon adsorption-desorption, high-energy X-ray total scattering, Raman and solid-state NMR spectroscopy, and high-resolution transmission electron microscopy. It was revealed that the formation of amorphous TEA(+)-aluminosilicate composites and their structural, chemical, and textural evolution toward the amorphous zeolite beta-like structure during the induction period is vital for the formation of zeolite beta. A comprehensive scheme of the formation of zeolite beta is proposed paying attention to the clustered behavior of TEA(+) as follows: (i) the formation of the TEA(+)-aluminosilicate composites after heating, (ii) the reorganization of aluminosilicates together with the conformational rearrangement of TEA(+), yielding the formation of the amorphous TEA(+)-aluminosilicate composites with the zeolite beta-like structure, (iii) the formation of zeolite beta nuclei by solid-state reorganization of such zeolite beta-like, TEA(+)-aluminosilicate composites, and (iv) the subsequent crystal growth. It is anticipated that these findings can provide a basis for broadening the utilization of OSDAs in the clustered mode of structure direction in more effective ways.

Symbiosis island shuffling with abundant insertion sequences in the genomes of extra-slow-growing strains of soybean bradyrhizobia.

Extra-slow-growing bradyrhizobia from root nodules of field-grown soybeans harbor abundant insertion sequences (ISs) and are termed highly reiterated sequence-possessing (HRS) strains. We analyzed the genome organization of HRS strains with the focus on IS distribution and symbiosis island structure. Using pulsed-field gel electrophoresis, we consistently detected several plasmids (0.07 to 0.4 Mb) in the HRS strains (NK5, NK6, USDA135, 2281, USDA123, and T2), whereas no plasmids were detected in the non-HRS strain USDA110. The chromosomes of the six HRS strains (9.7 to 10.7 Mb) were larger than that of USDA110 (9.1 Mb). Using MiSeq sequences of 6 HRS and 17 non-HRS strains mapped to the USDA110 genome, we found that the copy numbers of ISRj1, ISRj2, ISFK1, IS1632, ISB27, ISBj8, and IS1631 were markedly higher in HRS strains. Whole-genome sequencing showed that the HRS strain NK6 had four small plasmids (136 to 212 kb) and a large chromosome (9,780 kb). Strong colinearity was found between 7.4-Mb core regions of the NK6 and USDA110 chromosomes. USDA110 symbiosis islands corresponded mainly to five small regions (S1 to S5) within two variable regions, V1 (0.8 Mb) and V2 (1.6 Mb), of the NK6 chromosome. The USDA110 nif gene cluster (nifDKENXSBZHQW-fixBCX) was split into two regions, S2 and S3, where ISRj1-mediated rearrangement occurred between nifS and nifB. ISs were also scattered in NK6 core regions, and ISRj1 insertion often disrupted some genes important for survival and environmental responses. These results suggest that HRS strains of soybean bradyrhizobia were subjected to IS-mediated symbiosis island shuffling and core genome degradation.

Extensive preferential pathway ablation for the elimination of premature ventricular contractions arising from the right ventricular outflow tract.

A 76 y/o women presented with 2 different types of premature ventricular contractions (VPCs 1 and 2) arising from the right ventricular outflow tract (RVOT). Catheter ablation (CA) eliminated PVC1 at the earliest activation site (EAS), but thereafter another PVC morphology (PVC3) appeared. Small potentials preceding the local potential were broadly exhibited from the RVOT's supero-anterior region to the EAS during PVC3. Point CA targeting such pre-potentials failed. Transverse-linear CA with a line connecting sites with such pre-potentials eliminated both PVCs 3 and 2. In cases with broadly spreading preferential pathways, extensive CA might be needed to eliminate the PVCs.

[Coexistence of lymphoid follicular proctitis and ulcerative colitis].

We describe a rare case of ulcerative colitis (UC) with lymphoid follicular proctitis (LFP) extending discontinuously from the rectum to the ascending colon. The patient was a 42-year-old female presenting with a positive fecal occult blood test. Colonoscopy revealed erosions and disappearance of vascular patterns in the ascending colon and lower rectum, together with circumferential, uniform, granular lesions in the lower rectum. Histological examinations of the rectal biopsy specimens revealed lymphoid follicles, hyperplasia, and infiltration of chronic inflammatory cells. We suspected rectal and segmental UC with LFP. Initially, the patient was managed conservatively because of the lack of symptoms; however, on developing mucoid stools and haematochezia, mesalazine administration was started. Her symptoms and endoscopic findings resolved completely. LFP is closely associated with UC. Therefore, while diagnosing and managing LFP, it is necessary to ascertain or rule out potential complications.

Factors predicting bone mineral density (BMD) changes in young women over a one-year study:changes in body weight and bone metabolic markers during the menstrual cycle and their effects on BMD.

Currently, 26% of Japanese women in their twenties are under weight, and therefore at risk of developing various metabolic abnormalities due to an inadequate nutrient intake, which in turn affects the acquisition of a peak bone mineral density (BMD). In this study, we aimed to clarify the effects of menstrual cycle-related changes in body weight and bone metabolic marker levels on the BMD changes. The subjects were 42 women (19.6 ± 0.8 years). The levels of osteocalcin (OC), BAP, s-NTx, u-DPD, and E2 in the menstrual and ovulatory phases were measured. The associations between dependent variables (BMD changes/year in the lumbar spine, femur, femoral neck) and explanatory variables (body weight changes/year, the levels of OC, BAP, s-NTx, u-DPD) were evaluated using multiple regression analysis. Analysis of the correlations between the changes in bone metabolic markers and changes in BMD showed a correlation between the OC level in the menstrual phase and changes in the BMD of the entire femur, suggesting that a high OC level protects against BMD reduction, probably by promoting osteoblast activity, and that bone formation activity suppresses the decrease in BMD. These results suggest that, to predict BMD changes from bone metabolic markers in young women, it is necessary to measure OC levels in the menstrual phase.

Effect of ganglionated plexi ablation by high-density mapping on long-term suppression of paroxysmal atrial fibrillation - The first clinical survey on ablation of the dorsal right plexusus.

BACKGROUND: Long-term outcomes of suppressing paroxysmal atrial fibrillation (PAF) with additive ganglionated plexus (GP) ablation (GPA) remains unknown. OBJECTIVES: The aim of the study is to assess potential role of additional GPA for PAF suppression. METHODS: This study consisted of 225 patients; 68 (group A: 58 male, aged 60 ± 11 years) underwent pulmonary vein isolation (PVI) alone and 157 (group B: 137 male, aged 61 ± 11 years) GPA followed by PVI. GPA was performed based on the high-density mapping with high-frequency stimulation (HFS) delivered to left atrial (LA) major GP. The latter 85 group B patients (54%) underwent ablation to a posteromedial area within superior vena cava as a part of dorsal right atrial GP (SVC-Ao GP). RESULTS: In group B, HFS was applied to 126 ± 32 sites, with a median of 47 GP sites (40.0%) being ablated. In patients undergoing an SVC-Ao GPA, HFS and the SVC-Ao GPA were applied at a median of 15 and 4 sites (29.4%), respectively. The PVI with a GPA provided higher PAF suppression than a PVI alone during more than 4 years of follow-up (56.7% vs 38.2%, odds ratio: 0.42, 95% confidence interval: 0.23-0.76, P < .05), but the SVC-Ao GPA did not provide further suppressive effects. Multivariate analyses revealed that tachycardia-bradycardia syndrome and non-PV foci were independent predictors of PAF recurrence after PVI with a GPA (P < .01). CONCLUSION: GPA to LA major GP by high-density mapping provides long-term benefits for PAF suppression over 4 years of follow-up, but the effect of an empiric SVC-Ao GPA could not be appreciated, suggesting little effect on suppressing non-PV foci.

Impact of bedrest on cardiovascular events and complications associated with temporary pacemakers in patients waiting for permanent pacemaker implantation.

BACKGROUND: Patients with a temporary pacemaker (TPM) for bradycardias are required to maintain bedrest until permanent pacemakers (PPMs) are implanted because of the development of Adams-Stokes syndrome, worsening heart failure, or complications associated with TPMs is anticipated. However, bedrest may be detrimental in patients because it leads to disuse syndrome. This study examined whether bedrest could decrease the incidence of cardiovascular events or complications associated with TPMs in patients waiting for PPM implantation. METHODS: We conducted a retrospective cohort study on 88 patients who had emergency hospitalization for the treatment of bradycardias, and a TPM was inserted during the waiting period before PPM implantation. We divided patients into two groups according to whether they underwent bedrest (Bedrest Group) or not (Ambulation Group) during the period that patients were supported with TPM. We evaluated whether bedrest was a predictor of adverse events using a logistic regression analysis. RESULTS: Adverse events occurred in 31 patients (35%). In the univariate analysis, there was no significant difference in the incidence of adverse events between the Bedrest and Ambulation Groups (39% vs. 29%). In the logistic regression analysis, bedrest was not a predictor of adverse events (odds ratio, 1.40; 95% confidence interval, 0.53-3.68, P = .497). CONCLUSIONS: In patients with TPMs for bradyarrhythmias during the waiting period for PPM implantations, bedrest might not prevent adverse events, such as cardiovascular events and complications associated with TPMs.

[A case of pneumatosis cystoides intestinalis associated with ulcerative colitis].

Pneumatosis cystoides intestinalis (PCI) is associated with various diseases, but rarely with inflammatory bowel disease. We describe a rare case of PCI associated with ulcerative colitis. The patient was a 30-year-old man with ulcerative colitis (UC), which was in remission under immunomodulator therapy. Colonoscopic examination around 2 years after a diagnosis of UC revealed multiple hemispherical submucosal tumors (SMT) in the ascending colon and hepatic flexure, with erosion and disappearance of vascular network patterns in the rectum. PCI was diagnosed from the result of colonoscopic examination and computed tomography, and had not changed on colonoscopic examination 2 months later, without any treatment.

Evaluation of the Pharmacokinetics, Safety, and Tolerability of a Single Oral Dose of Pyrimethamine in Healthy Male Subjects of Japanese and European Ancestry.

The pharmacokinetics of pyrimethamine have been evaluated in various populations but have not been reported in subjects of Japanese ancestry following administration as a single-agent tablet. Furthermore, although pyrimethamine pharmacokinetics after a single dose of the single-agent tablet studied in Western countries have been reported, these studies are old, and the ancestry of the subjects was not specified. Consequently, this study investigated the pharmacokinetics and safety of a single oral 50-mg dose of pyrimethamine in healthy male subjects of Japanese and European ancestry. Seven subjects of each ancestry group were administered pyrimethamine, along with calcium folinate. After absorption, pyrimethamine was eliminated, with a mean half-life of 122.8 hours in Japanese subjects and 99.5 hours in European subjects. The mean Cmax and AUC0-t were 433.8 ng/mL and 59.63 µg·h/mL in Japanese subjects and 372.7 ng/mL and 42.83 µg·h/mL in European subjects. No safety concerns were reported during the study. Although pyrimethamine exposure was slightly higher in subjects of Japanese than of European ancestry, a considerable overlap in the range of parameter values was observed. Considering the range of pyrimethamine exposure reported previously, difference in exposure observed in this study would not be considered of note.

Evaluation of the Safety, Tolerability, Pharmacokinetics, and Food Effect of Danirixin Hydrobromide Tablets in Japanese Healthy Elderly Participants.

Danirixin is a selective and reversible CXC chemokine receptor 2 antagonist that may be useful for the treatment of respiratory diseases such as chronic obstructive pulmonary disease. This study aimed to evaluate the safety, tolerability, and pharmacokinetics of danirixin after administration of single oral doses of 10, 50, and 100 mg danirixin hydrobromide (HBr) tablets in the fed state (high-fat meal) (part 1) and to evaluate the food effect (low-fat meal) on the pharmacokinetics of danirixin after administration of a single oral dose of 50 mg danirixin HBr tablets (part 2). A total of 34 Japanese healthy elderly male participants were enrolled; 18 participants were included in part 1, and 16 in part 2. The systemic exposure to danirixin (maximum blood concentration [Cmax ] and area under the concentration-time curve [AUC0-t ]) increased in an approximately dose-proportional manner. The exposure to danirixin was lower in the fed state (low-fat meal) than in the fasted state (a 56% and 35% decrease in Cmax and AUC0-t , respectively). This first study of danirixin in Japanese healthy elderly participants showed a favorable safety profile with no drug-related adverse events and no clinically significant concerns in clinical laboratory values, vital signs, ocular examination, or electrocardiograms.

Mesoporous Rh Emerging from Nanophase-separated Rh-Y Alloy.

Mesoporous precious metals with abundant active sites and high surface area have been widely recognized as high-performance catalytic materials. However, the templated synthesis is complex and costly. Herein, we report a mesoporous rhodium (m-Rh) that can be readily synthesized from entangled nanofibres of Rh and Y2 O3 without templates. The entangled nanofibres, prepared from uniform Rh-Y alloys under redox atmosphere, were the key precursor in the synthesis processes. Moreover, the m-Rh efficiently catalyzed carbon dioxide reforming of methane (DRM) at a low reaction temperature of 683 K. Further, electrochemical methods of CO electro-oxidation were innovatively used to demonstrate the stability of CO and oxygen species for the DRM reaction.

Adsorptive depletion of elevated proinflammatory CD14+CD16+DR++ monocytes in patients with inflammatory bowel disease.

BACKGROUND: In human blood, two monocyte populations exist, CD14(++)CD16(-) classical monocytes and CD14(+)CD16(+) proinflammatory monocytes, which account for about 10% of total monocytes, but can expand to promote inflammatory conditions. CD14(+)CD16(+) monocytes produce large amounts of inflammatory cytokines including TNF-alpha and IL-1. Adacolumn adsorptive carriers adsorb from the blood in the column most of the monocytes/macrophages and granulocytes and this has been associated with clinical efficacy in patients with active inflammatory bowel disease (IBD). This study was to investigate the CD14(+)CD16(+) monocyte profile in patients with IBD and the impact of Adacolumn on this proinflammatory phenotype. METHODS: A total of 58 patients with ulcerative colitis (UC, N = 37) or Crohn's disease (CD, N = 21) together with 11 healthy controls were included in this study. Peripheral blood CD14(+)CD16(+) monocytes were determined by three-color immunofluorescence and flow cytometry. RESULTS: The percentage of CD14(+)CD16(+) monocytes in patients with active CD was significantly (P= 0.0089) higher than the level in the control group, in patients with quiescent CD (P= 0.0419) or quiescent UC (P= 0.0063). Further, the percentage of CD14(+)CD16(+) monocytes in patients with active UC who were on prednisolone (PSL) was less than the level in those not on PSL (P < 0.0001), thus PSL might have a suppressive effect on CD14(+)CD16(+) monocytes. Patients with active IBD were each given up to 10 Adacolumn granulocye/monocyte adsorption (GMA) sessions over an 8-wk period. The percentage of CD14(+)CD16(+) monocytes decreased dramatically (P= 0.0077 in UC and P= 0.0117 in CD) compared with entry levels. CONCLUSIONS: A significant reduction in peripheral CD14(+)CD16(+) monocytes by GMA should mitigate the inflammatory drive and contribute to the clinical efficacy of this procedure. Reduction of CD14(+)CD16(+) monocytes by corticosteroids was also seen. Hence, corticosteroids should enhance the efficacy of GMA. This is the first report on CD14(+)CD16(+) monocytes being decreased by Adacolumn GMA in patients with IBD.

Electrocardiographic characteristics associated with in-hospital outcome in patients with left main acute coronary syndrome: For contriving a new risk stratification score.

AIM: The aim of this study was to evaluate electrocardiographic characteristics associated with in-hospital prognosis in patients with left main acute coronary syndrome. METHODS AND RESULTS: A total of 89 left main acute coronary syndrome subjects were selected from 3357 consecutive acute coronary syndrome patients (2.7%). Patients of this study were divided into two groups; those who survived and those who died. Patients' characteristics and electrocardiogram on admission were then retrospectively analyzed between the two groups. In-hospital mortality was 28.1%. The prevalence and degree of ST-segment elevation at lead aVL were significantly higher in the deceased group than in the survival group ( p<0.001). However, those at lead aVR did not show significant differences between the two groups. Moreover, the width of the QRS-complex was significantly wider (lead V3; p<0.001), and the level of five minus the absolute value of five minus number of ST-segment elevation (5-|5-ST|; due to the highest in-hospital mortality (70%) in the five-lead ST-segment elevation group) was significantly larger in the deceased group than in the survival group ( p<0.001). The odds ratios that predicted in-hospital cardiac death were 1.03 for width of the QRS-complex at lead V3 (95% confidence interval (CI); 1.01-1.06; p=0.003), 1.74 for 5-|5-ST| (95% CI; 1.03-3.00; p=0.040), and 1.44 for ST-segment elevation at lead aVL (95% CI; 0.93-2.23; p=0.100). CONCLUSIONS: ST-segment elevation at lead aVL rather than aVR, width of the QRS-complex at lead V3 and number of ST-segment elevation were the prognostic predictors for in-hospital mortality in patients with left main acute coronary syndrome. Electrocardiographic characteristics should be assessed in addition to the established risk score in patients with left main acute coronary syndrome.

A multicenter retrospective study aiming to identify patients who respond well to adsorptive granulomonocytapheresis in moderately to severely active ulcerative colitis.

OBJECTIVES: Adsorptive granulomonocytapheresis (GMA) with the Adacolumn has been introduced as a non-pharmacologic treatment for ulcerative colitis (UC). However, a subset of patients who might respond well to GMA needs to be targeted. This study was conducted at three IBD centers to determine factors affecting the efficacy of GMA in patients with moderately-to-severely active UC. METHODS: From January 2008 to December 2017, a total of 894 active episodes (first attack or relapse) in 593 patients were treated with GMA. Clinical remission was defined as normal stool frequency and no rectal bleeding. Multiple clinical and laboratory parameters at entry were considered for efficacy assessment. RESULTS: Clinical remission was achieved during 422 (47%) of the 894 treatment cases. In the multivariate analysis, predictors for favorable response to GMA were age ≤60 years, UC duration <1 year, Mayo endoscopic subscore 2 (vs. 3), steroid naïve UC, and biologic naïve UC. Clinical remission rate was 70% in patients with four of the five factors, 52% in patients with three factors, 46% in patients with two factors, 39% in patients with one factor, and 18% in patients with none of these factors. Overall, the clinical remission rate was significantly higher in patients with a greater number of the five predictors (P < 0.0001). CONCLUSIONS: GMA appeared to be effective in steroid naïve and biologic naïve patients with short duration of UC. Elderly patients (>60 years) and those with severe endoscopic activity did not respond well to GMA. Additional, well designed, prospective, controlled trials should strengthen our findings.
