Doubling the life of Cu/ZnO methanol synthesis catalysts via use of Si as a structural promoter to inhibit sintering.

Cu/ZnO/AlO catalysts used to synthesize methanol undergo extensive deactivation during use, mainly due to sintering. Here, we report on formulations wherein deactivation has been substantially reduced by the targeted use of a small quantity of a Si-based promoter, resulting in accrued activity benefits that can exceed a factor of 1.8 versus unpromoted catalysts.

Early outcomes of total hip arthroplasty using point-of-care manufactured patient-specific instruments: a single university hospital's initial experience.

Background: The use of 3D-printed Patient-Specific Instruments (PSI) has been investigated to enhance the postoperative functional results in total hip arthroplasty (THA) and has been recognized as an innovative approach for the optimal alignment of hip implant components. Point-of-care production is gradually becoming the norm for PSI manufacturing. The purpose of this article is to assess the accuracy and safety of PSI for total hip arthroplasty performed at the point-of-care in Vietnam.

Reflections on the concept of optimality of single decision point treatment regimes.

In many areas, applied researchers as well as practitioners have to choose between different solutions for a problem at hand; this calls for optimal decision rules to settle the choices involved. As a key example, one may think of the search for optimal treatment regimes (OTRs) in clinical research, that specify which treatment alternative should be administered to each patient under study. Motivated by the fact that the concept of optimality of decision rules in general and treatment regimes in particular has received so far relatively little attention and discussion, we will present a number of reflections on it, starting from the basics of any optimization problem.

Total humerus replacement with reverse shoulder design for non-oncologic indication: A case report.

Among them, the bone marrow is commonly used source and a research subject for methods using stem cells to promote wound healing process.

Novel technique for scapulothoracic arthroscopy: A case report of the application of intraoperative 3D imaging.

Introduction: Snapping shoulder syndrome could be effectively treated with scapulothoracic arthroscopy. The excision of the scapular superomedial corner is assumed to help lower the recurrence rate. However, the amount of resection is still controversial.

Production of Sucrolytic Enzyme by by the Bioconversion of Pomelo Albedo as a Carbon Source.

Recently, there has been increasing use of agro-byproducts in microbial fermentation to produce a variety of value-added products. In this study, among various kinds of agro-byproducts, pomelo albedo powder (PAP) was found to be the most effective carbon source for the production of sucrose hydrolyzing enzyme by TKU004. The optimal medium for sucrolytic enzyme production contained 2% PAP, 0.

Total femur replacement in a patient with chronic persistence osteomyelitis - A case report.

Introduction And Importance: Total femoral replacement (TFR) is a salvage surgical procedure that has been indicated mainly for oncologic indication to avoid lower limb amputation but has recently been indicated for non-oncological disorders.

Case Presentation: We report the case of a 63-year-old male with chronic osteomyelitis of the left femur, severe pain and bone deformation, the risk of amputation in this patient was very high. The patient underwent total femur replacement (TFR) with a modular mega-prosthesis.

Assessment of oral health in older adults by non-dental professional caregivers-development and validation of a photograph-supported oral health-related section for the interRAI suite of instruments.

Objectives: An optimized oral health-related section and a video training were developed and validated for the interRAI suite of instruments. The latter is completed by professional non-dental caregivers and used in more than 40 countries to assess care needs of older adults.

Methods: The optimized oral health-related section (ohr-interRAI) consists of nine items and a video training that were developed in consecutive phases.

Serial correlation structures in latent linear mixed models for analysis of multivariate longitudinal ordinal responses.

We propose a latent linear mixed model to analyze multivariate longitudinal data of multiple ordinal variables, which are manifestations of fewer continuous latent variables. We focus on the latent level where the effects of observed covariates on the latent variables are of interest. We incorporate serial correlation into the variance component rather than assuming independent residuals.

Assessment of oral health conditions presented in photographs - is there a difference between dentists and non-dental professional caregivers?

Background: Photographs can help non-dental professional caregivers to identify problems when inspecting the mouth of care-dependent older individuals. This study evaluated whether the assessment of oral health-related conditions presented in photographs differed between dentists and non-dental professional caregivers.

Materials And Methods: One-hundred-and-seventy-nine photographs were taken from long-term care facility residents and from patients at the Department of Dentistry of a University Hospital.

Bioprocessing of Squid Pens Waste into Chitosanase by sp. TKU047 and Its Application in Low-Molecular Weight Chitosan Oligosaccharides Production.

Chitosan oligosaccharide (COS) has become of great interest in recent years because of its worthy biological activities.

We propose a Bayesian latent Ornstein-Uhlenbeck (OU) model to analyze unbalanced longitudinal data of binary and ordinal variables, which are manifestations of fewer continuous latent variables. We focus on the evolution of such latent variables when they continuously change over time. Existing approaches are limited to data collected at regular time intervals.

Understanding the mechanochemical synthesis of the perovskite LaMnO and its catalytic behaviour.

Mechanochemistry offers a solventless, 'waste free' route to preparing metal oxide catalysts, however, there is limited information on the chemical steps involved. In this work, the perovskite LaMnO has been successfully synthesized via mechanochemistry from metal oxide powders, LaO and MnO, at room temperature, using a planetary ball mill. Separate ex situ'time slices' were taken during the milling procedure to provide insights into the underlying chemistry.
