One of the major obstacles in process of lignocellulosic biorefinery is the utilization of pre-hydrolysate from pre-treatment. Although lignocellulosic pre-hydrolysate can serve as an economic starting material for xylonic acid production, the advancement of xylonic acid or xylonate is still limited by further commercial value or applications. In the present study, xylose in the high concentration wheat straw pre-hydrolysate was first in-situ biooxidized to xylonate by Gluconobacter oxydans. To meet the needs of commercialization, crude powdered calcium xylonate was prepared by drying process and calcium xylonate content in the prepared crude product was more than 70%...

In the present paper we report a low cost, single step preparation method for the synthesis of CuO-ZnO nanocomposite through simple co-precipitation technique using oxalic acid. To have a better idea about the deviations brought about by the inclusion of CuO in ZnO lattice, pure ZnO nanoparticles synthesized from 0.1M solutions were also investigated. X-ray diffraction studies showed that the composite contains only hexagonal wurtzite ZnO and monoclinic CuO structures. The magnetic studies of CuO-ZnO heterostructures were also conducted in order to elucidate the source of the ferromagnetism observed at room temperature...

PURPOSE OF REVIEW: Treatment of mineral metabolism is a mainstay of dialysis care including some of its most widely used and costly pharmaceuticals. Although many mineral metabolites are associated with increased risk of mortality, cardiovascular disease, and other morbidities, few clinical trials are available to guide therapy and most focus on single drug approaches. In practice, providers manage many aspects of mineral metabolism simultaneously in integrated treatment approaches that incorporate multiple agents and changes in the dialysis prescription...

Current guidelines recommend a 2-drug antiretroviral regimen as an alternative to triple antiretroviral therapy (ART) in selected patients to reduce long-term toxicity and costs. Areas covered: This review is intended to provide insight into the efficacy, safety and tolerability of 2-drug versus 3-drug ART in naïve and in treatment-experienced virologically-suppressed patients. Expert opinion: Dual therapy regimens are not feasible in HBV-coinfected individuals and should not be applied during pregnancy. Positive data on 2-drug ART in drug naïve patients are still limited, while, in virologically-suppressed individuals, several regimens have shown non-inferiority as compared to 3-drug regimens...

BACKGROUND AND AIMS: Tuberculosis (TB) patients who quit smoking have much better disease outcomes than those who continue to smoke. Behavioural support combined with pharmacotherapy is the most effective strategy in helping people to quit, in general populations. However, there is no evidence for the effectiveness of this strategy in TB patients who smoke. We will assess the safety, effectiveness and cost-effectiveness of cytisine - a low-cost plant-derived nicotine substitute - for smoking cessation in TB patients compared with placebo, over and above brief behavioural support...

Eutrophication of urban rivers has caused severe environmental problems due to the pollution from point and diffuse sources. Although eutrophication can be alleviated by reducing the input to the river system, fast-treating terminal control technologies, especially under emergent situations, should be developed to reduce risks induced by eutrophication. The present study developed an emergency purification device based on dissolved air flotation (DAF) technology. After equipment commissioning and parameter optimization for applications in the field of engineering, the device was found to effectively remove total phosphorus, chlorophyll a, chemical oxygen demand, and turbidity in water by controlling the coagulant dosage and adjusting the gas-liquid mixing pump parameters...

With healthcare costs on the rise, a global initiative was launched in 2007, called Exercise is Medicine, to prescribe and counsel patients on exercise to aid in the prevention and treatment of chronic diseases. Since community pharmacists are one of the most accessible healthcare providers, this is an opportunity for pharmacists to also engage in this initiative. This study aimed to assess pharmacy student perceptions and knowledge on exercise to determine whether they are adequately prepared to counsel patients on exercise prescription...

BACKGROUND: Systemic antibiotics are often used to treat rosacea and tetracyclines are the most common antibiotic prescribed; however, there is ambiguity among clinical guideline suggestions. Importantly, there is an increasing call to all clinicians to curtail antibiotic use. OBJECTIVE: Investigate the utilization and cost of long-term oral antibiotic use for the treatment of rosacea, including ocular rosacea. METHODS: This was a retrospective cohort study of MarketScan® Commercial Claims and Encounters database, from January 1, 2005 through December 31, 2014...

INTRODUCTION: Treatment guidelines recommend a stepwise approach to glycemia management in patients with type 2 diabetes (T2D), but this may result in uncontrolled glycated hemoglobin A1c (HbA1c) between steps. This retrospective analysis compared clinical and economic outcomes among patients with uncontrolled T2D initiating two oral antidiabetes drugs (OADs), glucagon-like peptide-1 receptor agonists (GLP-1 RAs), or basal insulin in a real-world setting. METHODS: Adults with T2D on OAD monotherapy were identified in the MarketScan claims database (2007-2014)...

Tuberculosis (TB) remains one of the most deadly infections with approximately a quarter of cases not being identified and/or treated mainly due to a lack of resources. Rapid detection of TB or drug-resistant TB enables timely adequate treatment and is a cornerstone of effective TB management. We evaluated the analytical performance of a single-tube assay for multidrug-resistant TB (MDR-TB) on an experimental platform utilising RT-PCR and melting curve analysis that could potentially be operated as a point-of-care (PoC) test in resource-constrained settings with a high burden of TB...

Physical inactivity represents the fourth leading risk factor for mortality, and it has been linked with a series of chronic disorders, the treatment of which absorbs ~ 85% of healthcare costs in developed countries. Conversely, physical activity promotes many health benefits; endurance exercise in particular represents a powerful stimulus to induce mitochondrial biogenesis, and it is routinely used to prevent and treat chronic metabolic disorders linked with sub-optimal mitochondrial characteristics. Given the importance of maintaining a healthy mitochondrial pool, it is vital to better characterize how manipulating the endurance exercise dose affects cellular mechanisms of exercise-induced mitochondrial biogenesis...

BACKGROUND: Antifungal treatment is common in critically ill patients, but only a small proportion of patients receiving antifungals have a proven fungal infection. However, antifungal treatment has side effects such as toxicity, emergence of resistance, and high cost. Moreover, empirical antifungal treatment is still a matter for debate in these patients. Our study aimed to determine the incidence, associated factors, and safety of de-escalation of antifungals in critically ill patients...

Large osteochondral allograft (OCA) transplant has become a valid alternative to restore articular surface in challenging articular lesions in young and active patients, either in primary or in revision procedures. Several studies support the effectiveness and safety of OCA, but costs and graft availability limit their use. The indications are the treatment of symptomatic full-thickness cartilage lesions greater than 3 cm 2 , deep lesions with subchondral damage, or revision procedures when a previous treatment has failed...
