Antimicrobial Prescription Practices and Stewardship in Washington State Small and Mixed Animal Veterinary Medicine.

Introduction: Judicious antimicrobial use is essential for the continued treatment of infections in small and mixed animal veterinary medicine. To better support Washington (WA) State veterinarians in antimicrobial stewardship, we surveyed licensed small and mixed animal veterinarians and led group conversations regarding antimicrobial prescription practices.

Methods: Survey questions included demographic information, factors influencing prescription practices and clinical cases.

Protein-protein interactions in solutions of monoclonal antibodies probed by the dependence of the high-frequency viscosity on temperature and concentration.

Using a quartz crystal microbalance with dissipation monitoring (QCM-D), the complex high-frequency viscosity, = η' - η'', of concentrated solutions of a monoclonal antibody (mAb) was studied with respect to its dependence on temperature, , and concentration, . Lysozyme and bovine serum albumin (BSA) served as reference materials. Viscoelasticity was found for the mAb solution, while the reference materials behaved like Newtonian liquids.

Contrasting endolithic habitats for cyanobacteria in spring calcites of the European Alps.

It is often difficult to decide which cyanobacteria found in endolithic habitats of calcite spring-tufa deposits are present as ephemeral components of the biota or are persistent, structural elements. To answer this question, we repeatedly studied two microhabitats of contrasting calcareous tufa springs in the European Alps. Pigment extracts, fluorescence probe measurements of samples and traditional microscopy confirmed the dominance of cyanobacteria over eukaryotic algae and their viability in both microhabitats.

Recovery of Ammonium Sulfate Solution by Regeneration of Loaded Clinoptilolite.

The zeolite clinoptilolite (CLI) is known to be a very good ion exchanger, as it consists of a three-dimensional structure formed of AlO and SiO tetrahedral, which are connected by a common oxygen atom. The micropores formed by this structure (with free diameters in the range of 0.40 nm and 0.

Sorption of recalcitrant phosphonates in reverse osmosis concentrates and wastewater effluents - influence of metal ions.

Magnetic microparticles functionalized with tailored ZnFeZr oxyhydroxide adsorbent were used for the reversible sorption of orthophosphate and recalcitrant organo-phosphonates from wastewater. The loaded particles were harvested magnetically from water, regenerated in an alkaline solution and reused numerous times. The applicability of the technology to treat brackish water reverse osmosis concentrates was tested under controlled synthetic conditions by investigating the influence of typical metals (Ca, Pb, Cu) on the removal of common phosphonates (HEDP, NTMP, EDTMP), and vice versa.
