The use of biomass for sorption of rare earth elements (REEs) has been the subject of many recent investigations. However, REE adsorption by bioengineered systems has been scarcely documented, and rarely tested with complex natural feedstocks. Herein, we engineered E. coli cells for enhanced cell surface-mediated extraction of REEs by functionalizing the OmpA protein with 16 copies of lanthanide binding tag (LBT). Through biosorption experiments conducted with leachates from metal-mine tailings and rare earth deposits, we show that functionalization of the cell surface with LBT yielded several notable advantages over the non-engineered control...

Septic arthritis of the temporomandibular joint as a complication of acute otitis media is rare in the Western world. This report describes the case of a 7-year-old boy who had pain in his right ear and limited mouth opening, following the onset of acute otitis media. A contrast-enhanced computed tomography scan revealed right-sided mastoiditis and hydrops of the right temporomandibular joint, suggesting septic arthritis. Real-time PCR and microbiologic analysis identified Streptococcus pyogenes and Staphylococcus epidermidis in the joint aspirate...

Metabolic stress diminishes smooth muscle contractile strength by a poorly defined mechanism. To test the hypothesis that metabolic stress activates a compensatory cell signaling program to reversibly downregulate contraction, arterial rings and bladder muscle strips in vitro were deprived of O2 and glucose for 30 and 60 min ("starvation") to induce metabolic stress, and the phosphorylation status of proteins involved in regulation of contraction and metabolic stress were assessed in tissues under basal and stimulated conditions...

Proof-of-pharmacology models to study compounds in healthy subjects offer multiple advantages. Simvastatin is known to induce mitochondrial dysfunction at least partly by depletion of co-enzyme Q10. The goal of this study was to evaluate a model of simvastatin-induced mitochondrial dysfunction in healthy subjects and to determine whether mitochondrial dysfunction could be pharmacologically reversed by treatment with co-enzyme Q10 (ubiquinol). Subjects received simvastatin 40mg/day for 8 weeks. After 4 weeks, subjects were randomized to receive ubiquinol 300mg/day or placebo in a double-blinded fashion...

BACKGROUND: Enhanced recovery pathways (ERPs) are bundled best-practice process measures associated with reduction of preventable harm, decreased length of stay (LOS), and increased overall value of care. An auditing procedure was developed to assess compliance with 18 ERP process measures and establish a system for identifying and addressing defects in measure implementation. METHODS: For a one-year period, the electronic health records of 413 consecutive patients treated on a multidisciplinary ERP for colorectal surgery at an academic medical center were evaluated with the audit procedure...

The aim of the present study was to explore the effect of exogenous application of castasterone (CS) on physiologic and biochemical responses in Brassica juncea seedlings under copper (Cu) stress. Seeds were pre-soaked in different concentrations of CS and grown for 7 days under various levels of Cu. The exposure of B. juncea to higher levels of Cu led to decrease of morphologic parameters, with partial recovery of length and fresh weight in the CS pre-treated seedlings. Metal content was high in both roots and shoots under Cu exposure while the CS pre-treatment reduced the metal uptake...

Biologics are the most rapidly growing class of therapeutics, but commonly suffer from low stability. Peroral administration of these therapeutics is an attractive delivery route; however, this route introduces unique physiological challenges that increase the susceptibility of proteins to lose function. Formulation of proteins into biomaterials, such as electrospun fibers, is one strategy to overcome these barriers, but such platforms need to be optimized to ensure protein stability and maintenance of bioactivity during the formulation process...

Sex differences in patterns of methamphetamine (MA) abuse have been reported with females (humans and rodents) showing an elevated addiction phenotype. Previous findings indicate MA-induced hypothalamic-pituitary-adrenal (HPA) axis activation is also sexually dimorphic with females exhibiting an elevated glucocorticoid release and differential neural activation patterns within HPA axis-associated brain regions. These effects may contribute to sex differences in abuse. To determine the role of gonadal hormones in mediating sex differences in MA-induced glucocorticoids, male and female C57BL/6J mice were gonadectomized or sham-operated, and following recovery, injected with MA (5 mg/kg) and sacrificed 60 minutes or 120 minutes later...

Single-walled carbon nanotubes (SWCNTs) exhibit intrinsic near-infrared fluorescence that benefits from indefinite photostability and tissue transparency, offering a promising basis for in vivo biosensing. Existing SWCNT optical sensors that rely on charge transfer for signal transduction often require exogenous mediators that compromise the stability and biocompatibility of the sensors. This study presents a reversible, mediatorless, near-infrared glucose sensor based on glucose oxidase-wrapped SWCNTs (GOx-SWCNTs)...

Goal-directed fluid therapy (GDFT) seeks to improve outcomes through individualized optimization of oxygen delivery using IV fluid and vasoactive infusions. Trials of GDFT show clinical benefits over traditional liberal fluid administration, but fail to demonstrate benefits when compared to a restrictive strategy within an optimized enhanced recovery protocol. The ideal monitors, hemodynamic goals, and fluid administration strategy are not well established but may be less important than rational application of thoughtful fluid management strategies...

Coordinated multidisciplinary perioperative care through enhanced recovery protocols has improved outcomes within urologic surgery. Continued development and refinement of enhanced recovery after surgery (ERAS) pathways will further augment the care of patients undergoing all urologic procedures. Among the challenges, moving forward is identification of barriers to ERAS adoption by providers, maximizing adherence among patients, standardization of ERAS pathways through establishment of evidence-based principles, and application in additional complex urologic procedures beyond radical cystectomy...

The cultivation of genetically modified crops (GMCs) has greatly increased worldwide. Given the fact that over 10 Bacillus thuringiensis Cry toxins have been applied in GMCs, there is a need to develop an efficient and economically affordable detection method that simultaneously screen such compounds with similar structures in crops and foodstuff. Here we described an approach using a site-directed mutagenesis that enhances the generic specificity of single chain variable fragment (scFv). After three rounds of panning against mixed antigen (Cry1Ab, Cry1Ac, Cry1B, Cry1C and Cry1F) from the constructed mutagenesis library, one mutant showed greater ability to bind to a range of Cry toxins...

In this study, the polysaccharide from Polygonatum sibiricum (PSP) was evaluated for the immunomodulatory activity by the cyclophosphamide (Cy)-induced immunosuppressed-model in vivo. The PSP has been analyzed in order to identify a variety of chemical properties such as monosaccharide compositions and structural confirmation. The results show that the main components of PSP were galactose and rhamnose. The PSP could significantly stimulate neutral red phagocytosis of RAW264.7 macrophages. Compared with the cyclophosphamide group, PSP accelerated recovery of spleen and thymus indexes, and enhanced T cell and B cell proliferation responses as well as peritoneal macrophage phagocytosis...

Herein, a facile solvent mediated silver nanoparticle (AgNP) mirror was introduced as a reproducible and sensitive surface-enhanced Raman scattering (SERS) substrate. The AgNP mirror was fabricated based on commercially available citrate coated AgNPs via a facile and unique water-solvent interface assembly method without using any electrical equipment. By adding 0.2 mg ml(-1) citrate coated AgNPs dropwise into a mediating solvent, self-assembled AgNP mirrors were formed instantly and gradually settled down at the bottom...

Procollagen C-proteinase enhancer 1 (PCPE-1) has been characterized as a protein capable of enhancing the activity of bone morphogenetic protein 1/tolloid-like proteinases in the biosynthetic processing of C-propeptides from procollagens I-III. This processing step is thought necessary to the formation of collagen I-III monomers capable of forming fibrils. Thus, PCPE-1 is predicted to play an important role in scarring, as scar tissue is predominantly composed of fibrillar collagen. Corneal scarring is of great clinical importance, as it leads to loss of visual acuity and, in severe cases, blindness...

Healthcare in general, and surgery/interventional care in particular, is evolving through rapid advances in technology and increasing complexity of care with the goal of maximizing quality and value of care. While innovations in diagnostic and therapeutic technologies have driven past improvements in quality of surgical care, future transformation in care will be enabled by data. Conventional methodologies, such as registry studies, are limited in their scope for discovery and research, extent and complexity of data, breadth of analytic techniques, and translation or integration of research findings into patient care...

BACKGROUND: Enhanced recovery protocols are widely used in many areas of general surgery but had a limited penetration in perioperative management of patients undergoing liver resection. Recently, multiple publications described application of enhanced recovery after surgery (ERAS) program to hepatectomy patients but their definitive role is not established or accepted by hepatobiliary surgeons. METHODS: A comprehensive literature review of published series in English language medical sources detailing ERAS program application for hepatectomy for the period of 2006-2016 is performed...

Axonal regeneration in the adult mammalian central nervous system is limited in part by the non-permissive environment, including axonal growth inhibitors such as the Nogo-A protein. How the functions of these inhibitors can be blocked remains unclear. Here, we examined the role of LOTUS, an endogenous Nogo receptor antagonist, in promoting functional recovery and neural repair after spinal cord injury (SCI), as well as axonal regeneration after optic nerve crush. Wild-type untreated mice show incomplete but substantial intrinsic motor recovery after SCI...
