Photocatalytic degradation of microcystins from a field-collected cyanobacterial assemblage by 3D printed TiO structures using artificial versus solar irradiation.

Microcystins (MCs) from freshwater cyanobacteria cause adverse effects to humans and ecological receptors through multiple exposure routes requiring adaptable and diverse treatment technologies. Photocatalysis of MCs using TiO is a promising technology; however, TiO photocatalysts as unbound nanoparticles in suspension are impractical to deploy. 3D Printing (3DP) provides a means to immobilize TiO, producing deployable photocatalyst structures with extensive geometric freedom.

Clinical outcomes of dogs with transitional cell carcinoma receiving medical therapy, with and without partial cystectomy.

The objective of this retrospective study was to evaluate the effects of surgery on outcome for dogs with naturally occurring urinary bladder transitional cell carcinoma. Forty-seven dogs met the inclusion criteria. Thirty-one dogs (Group A) were treated with partial cystectomy and adjunctive medical therapy and 16 dogs (Group B) were treated with medical therapy alone.

Multi-species Aquatic Toxicity Assessment of 1-Methyl-3-Nitroguanidine (MeNQ).

The Army is replacing traditional munitions with insensitive munitions (IM) resistant to accidental detonation. The aquatic toxicity of 1-methyl-3-nitroguanidine (MeNQ), which is being assessed for potential use in IM formulations, remains largely untested. The present study fills a number of critical data gaps for MeNQ aquatic toxicity by evaluating effects across two vertebrate and five invertebrate species.

Sensitivity of the Marine Calanoid Copepod Pseudodiaptomus pelagicus to Copper, Phenanthrene, and Ammonia.

There are limited acute toxicity test methods for native North American marine species that are considered zooplankton for their entire life cycle. Examples of standardized marine zooplankton methods include mussel, bivalve, and echinoderm development tests that use a relatively short-lived planktonic larval stage, chronic life-cycle toxicity tests using epibenthic copepods, and a 24-h Acartia tonsa copepod test method. The objectives of the present study were to: 1) develop and evaluate a novel, 48-h acute toxicity test method using the marine North American copepod Pseudodiaptomus pelagicus that is planktonic for its entire life cycle, and 2) determine the sensitivity of P.

A prospective, randomized, double blind, placebo-controlled evaluation of the effects of eicosapentaenoic acid and docosahexaenoic acid on the clinical signs and erythrocyte membrane polyunsaturated fatty acid concentrations in dogs with osteoarthritis.

Background: Osteoarthritis (OA) in dogs is a prevalent and serious condition. The most common treatment for the clinical signs of OA in dogs is the administration of nonsteroidal antiiflammatory pharmaceuticals. Omega-3 (n-3) fatty acids have been shown to reduce the clinical signs of osteoarthritis in dogs.

Factors associated with long-term survival in dogs undergoing liver lobectomy as treatment for liver tumors.

The objectives of the study were to describe clinicopathologic findings in dogs that underwent surgical treatment of liver tumors and to define outcome-associated variables in this canine population. Medical records of 118 dogs that underwent liver lobectomy were reviewed. Variables were assessed via univariate and multivariate Cox regression analyses.

Complications of hepatic surgery in companion animals.

The most common hepatic procedures performed in companion animals are liver biopsies and partial or complete liver lobectomies. Although these procedures are relatively simple to perform in healthy animals, surgery in clinical patients with liver disease is often complicated by the presence of significant systemic illness or by the technical challenges associated with removing massive hepatic tumors. An in-depth understanding of the possible complications that can occur with hepatic surgery helps to provide the best possible outcome for the patient by allowing the surgeon to not only take precautions to try to prevent complications but allows one to monitor for them postoperatively and treat them early if noted.

Spontaneous hemoperitoneum in cats: 65 cases (1994-2006).

Objective: To describe the clinical signs, physical examination findings, clinical laboratory abnormalities, etiology, and outcome in cats with spontaneous hemoperitoneum.

Design: Retrospective case series.

Animals: 65 client-owned cats with spontaneous hemoperitoneum.

Ovarian remnant syndrome in dogs and cats: 21 cases (2000-2007).

Objective: To describe signalment, clinical findings, diagnostic tests, and results of treatment of dogs and cats with ovarian remnant syndrome (ORS).

Design: Retrospective case series.

Animals: 19 dogs and 2 cats with ORS.

Phimosis in cats: 10 cases (2000-2008).

Medical records of 10 cats diagnosed with phimosis were reviewed. The most common clinical signs exhibited were stranguria and pollakiuria, which occurred in eight out of 10 cats. The diagnosis of phimosis was made from physical examination alone in all cats.
