Brand-new Strategy of Lowering Biofilm Building Bacterias inside Oral Cavity by Bismuth Nanoparticles.
Moreover, the hydrodynamic diameter of the modified Cu did not exceed 240 nm even after 60 days of preparation. The excellent dispersion behavior can be ascribed to the domination of the electrostatic repulsion forces over the inter-nanomaterials van der Waals interactions, which is related to the formation of the electrical adsorption layer on the Cu surface. The obtained colloidal dispersions have the potential to be utilized as green nanolubricants for lubricating tribological systems.As the efficient approaches for obtaining clean H2 energy, methanol oxidation (MOR) and water over slitting reactions have been increasingly essential. A series of novel semiconductive CoNi bimetal-organic framework (CoxNi3-x(HAB)2 MOF) have been prepared using hexaaminobenzene (HAB) as an organic linker. The obtained series of CoxNi3-x(HAB)2 MOFs were then explored as efficient multifunctional electrocatalysts for the non-Pt MOR and overall water splitting in alkaline medium. The basic characterizations of CoxNi3-x(HAB)2 MOFs revealed that they comprised multiple metal valence states (Co0/Co2+/Co3+ and Ni2+/Ni3+) and graphene-like nanostructures embedded with abundant CoNi alloy nanoparticles. Compared with the sole-metal MOFs (Co3(HAB)2 MOF and Ni3(HAB)2 MOF), the CoxNi3-x(HAB)2 MOF with a mass ratio of CoNi = 13 (CoxNi3-x(HAB)2 MOF-2) exhibited superior electrocatalytic performance for MOR. It gave a high current density of 92.8 mA cm-2 at 1.6 V vs. reversible hydrogen electrode (RHE) for MOR, along with the low overpotentials at the current density of 10 mV cm-2 (η10) and Tafel slopes toward hydrogen evolution reaction (η10 = 119 mV, Tafel slope = 46 mV dec-1) and oxygen evolution reaction (η10 = 1.35 V, Tafel slope = 26 mV dec-1). The analysis on the catalysis mechanism of MOR and water splitting in alkaline medium was also proposed. The voltages applied to the three- and two-electrode systems based on the bifunctional CoxNi3-x(HAB)2 MOF-2 catalyst for overall water splitting are 1.52 V vs. RHE and 1.45 V vs. silver/silver chloride (Ag/AgCl), respectively. This work provides a novel strategy for investigating the applications of promising two-dimensional semiconductive MOF as multifunctional electrocatalysts with boosted electrocatalytic activities in energy fields.Conventionally, His bundle pacing (HBP) is achieved using specially designed pacing leads and delivery sheaths. This paper describes the feasibility of permanent HBP with a pre-shaped simple stylet and a standard active-fixation electrode, through axillary vein access, without using dedicated delivery tools. This method may be a feasible and safe alternative to the only commercially available system.Left cardiac sympathetic denervation is reported to reduce the rate of events in young patients with channelopathy.•Horner syndrome and recurrence can be seen after left cardiac sympatetic denervation.•Bilateral cardiac sympathetic denervation in pediatric patient, is reported as a case report.•Bilateral cardiac sympathetic denervation is a safe procedure which reduces recurrence in channelopathies.Background Electrocardiographic left ventricular hypertrophy (LVH) has been used to predict adverse prognosis in hypertensive patients. This meta-analysis aimed to investigate the association between LVH using the different electrocardiographic criteria in patients with hypertension. ALK cancer Methods A comprehensive literature search was performed PubMed and Embase databases up to September 1, 2019. Observational studies evaluating the association between electrocardiographic LVH (Cornell voltage, Cornell product or Sokolow-Lyon voltage) at baseline and risk of stroke among hypertensive patients were selected. The risk ratio (RR) with 95% confidence interval (CI) was pooled for patients with electrocardiographic LVH versus without LVH. Results Seven studies enrolling 58,098 hypertensive patients were included. When compared those with or without LVH patients showed that the pooled RR of stroke was 1.63 (95% CI 1.38-1.93) for Cornell voltage criteria, 1.41 (95% CI 1.07-1.86) for Cornell product criteria, and 1.42 (95% CI 1.20-1.69) for Sokolow-Lyon voltage criteria, respectively. However, the predictive significance of Cornell product criteria was not reliable in the sensitivity analysis. Conclusions Baseline electrocardiographic LVH detecting by Sokolow-Lyon or Cornell voltage criteria can predict the development of stroke in hypertensive patients. Use of electrocardiographic LVH can improve stroke risk stratification in hypertensive patients.Purpose Rural Vietnam has been subject to continuous hygienic latrine interventions since the mid-1990s. However, most have concentrated on improving coverage rather than use. It is thus important to examine rural hygienic latrine use rates and the predictors impacting them. Accordingly, this can inform subsequent sanitation policy and enrich pertinent, rural health scholarship. Methods For this study, 792 adult household heads were surveyed in Giong Trom district, Ben Tre, Mekong Delta region, Vietnam. A logistic regression analysis was performed on household heads owning a hygienic and unhygienic latrine simultaneously (N = 140). Included use predictors were individual-contextual and RANAS. This permit assessments of behavioural or normative predictors that, in many instances, are absent from comparable studies. Predictors' statistical significance was set at p less then 0.03. Findings Unsatisfactory hygienic latrine use in Ben Tre, among hygienic latrine owners, exceeds 20%. Many owners (26.8%) choose to retain their unhygienic latrine when acquiring a hygienic one, resulting in a 46.4% unhygienic latrine use rate within this sub-group. Meanwhile, the only hygienic latrine use predictors with statistical significance are neighbours' behaviour, user preference and health-benefit beliefs. Conclusion The Ben Tre case underscores that hygienic latrine ownership or access does not ensure comprehensive use. This even applies to latrines that are clean, working and adequate privacy-providing. Sanitation interventions thus ought to consider a targeted, community-coverage approach with expansive health messaging and emphasis on behavioural change. Demographic or socioeconomic-particular targeting, however, is not always necessary no individual-contextual predictors proved statistically significant.
