INTRODUCTION: Treatment using abiraterone acetate, enzalutamide, cabazitaxel, and radium-223 (Ra-223) improve overall survival (OS) and quality of life for patients with metastatic castrate-resistant prostate cancer (mCRPC). Despite their proven benefits, access to these therapies is not equal across Canada. METHODS: We describe provincial differences in access to approved mCRPC therapies. Data sources include the pan-Canadian Oncology Drug Review database, provincial cancer care resources, and correspondence with pharmaceutical companies...

PURPOSE:  Dynamic graciloplasty (DGP) has been used to treat severe fecal incontinence since the 1980s. Previous studies have shown an inferior outcome in patients with anorectal malformations (ARMs). Our experience has been that DGP has been appreciated by ARM -patients. The objective of the study was to evaluate the long-term outcome of DGP in our patients with ARM compared with patients with other underlying conditions. MATERIALS AND METHODS:  Twenty-three patients operated with DGP at our institution from 1996 to 2010 were sent validated bowel function and quality of life questionnaires...

Fluorescence detection of various pharmaceuticals and the amino acid tryptophan (low molecular weight organic compounds) as well as the enzyme lactate dehydrogenase LDH (high molar mass compound) has been studied in aqueous solutions using alkyl ammonium formate ionic liquids as the primary solvent component. It was expected that the high viscosity of such ionic liquid-water mixtures would enhance fluorescence. Pharmaceuticals such as riboflavin and naproxen showed no such enhancement in the presence of ethylammonium formate (EAF) or isopropylammonium formate (IPAF) but the fluorescence of warfarin was substantially enhanced by a factor of 4 with 80% EAF and a factor of 7 with 70% IPAF...

Colorectal cancer (CRC) is one of the most prevalent cancers worldwide with rising mortality rates predicted in the coming decades. In light of this, there is a continued need for improvement in our understanding of CRC biology and the development of novel treatment options. Tumour-derived extracellular vesicles (tEVs) have emerged as both novel cancer biomarkers and functional mediators of carcinogenesis. tEVs are released by tumour cells in abundance and play an important role in mediating tumour cell - immune cell interactions in the tumour microenvironment...

Solvent-terminated dispersive liquid-liquid microextraction (ST-DLLME) is a special mode of DLLME in which a demulsifying solvent is injected into the cloudy mixture of sample/extractant to break the emulsion and induce phase separation. The demulsification process starts by flocculation of the dispersed microdroplets by Ostwald ripening or coalescence to form larger droplets. Then, the extractant either floats or sinks depending on its density as compared with that for the aqueous sample. The demulsifier should have high surface activity and low surface tension in order to be capable of inducing phase separation...

Thrips-infesting soybeans were considered of minor economic importance, but recent evidence of their ability to transmit a newly identified soybean virus, Soybean vein necrosis virus (SVNV), has raised their profile as pests. Season-long surveys were conducted using suction traps to determine the effects of temperature and precipitation on the spatiotemporal patterns of three vector species of SVNV, Neohydatothrips variabilis (Beach) (Thysanoptera: Thripidae) (soybean thrips), Frankliniella tritici (Fitch) (Thysanoptera: Thripidae) (eastern flower thrips), and Frankliniella fusca (Hinds) (Thysanoptera: Thripidae) (tobacco thrips) in soybean fields in Indiana in 2013 and 2014...

OBJECTIVE: Trauma exposure is common, with estimates of 28 to 90% of adults reporting at least one traumatic event over their lifetime. Those exposed to traumatic events are at risk for alcohol misuse (i.e., binge drinking), posttraumatic stress disorder (PTSD), or both. A potential underlying mechanism for this comorbidity is increased impulsivity-the tendency to act rashly. Little work to date has examined the impact of different impulsogenic traits on this comorbidity. METHODS: This study (n = 162) investigated trauma-exposed young adults (age 21-30) who had endorsed a lifetime interpersonal trauma...

Health system human resource departments are putting new requirements, paperwork, and processes in place to meet new Joint Commission standards for treating students like employees who onboard at the beginning of employment. These processes have significantly increased the workload of experiential education offices and present an additional burden to students. In an attempt to streamline these processes, health systems are contracting with third-party tracking and placement organizations. Converting this process to an electronic one (such as what third-party organizations offer) could present advantages; however, there are many concerns about going through a third-party organization that could control placement decisions...

Genetic modifications during development of paediatric groups 3 and 4 medulloblastoma are responsible for their highly metastatic properties and poor patient survival rates. PRUNE1 is highly expressed in metastatic medulloblastoma group 3, which is characterized by TGF-β signalling activation, c-MYC amplification, and OTX2 expression. We describe the process of activation of the PRUNE1 signalling pathway that includes its binding to NME1, TGF-β activation, OTX2 upregulation, SNAIL (SNAI1) upregulation, and PTEN inhibition...

Herein, we present the design and synthesis of 2(1H)-pyrazinone based HCV NS3 protease inhibitors and show that elongated R3 urea substituents were associated with increased inhibitory potencies over several NS3 protein variants. The inhibitors are believed to rely on β-sheet mimicking hydrogen bonds which are similar over different genotypes and current drug resistant variants and correspond to the β-sheet interactions of the natural peptide substrate. Inhibitor 36, for example, with a urea substituent including a cyclic imide showed balanced nanomolar inhibitory potencies against genotype 1a, both wild-type (Ki  = 30 nM) and R155K (Ki  = 2 nM), and genotype 3a (Ki  = 5 nM)...

Structure-kinetic relationship analyses and identification of dominating interactions for optimisation of lead compounds should ideally be based on intrinsic rate constants instead of the more easily accessible observed kinetic constants, which account also for binding-linked reactions. The intrinsic rate constants for sulfonamide inhibitors and pharmacologically relevant isoforms of carbonic anhydrase were determined by a novel surface plasmon resonance (SPR) biosensor-based approach, using chemodynamic analysis of binding-linked pH-dependent effects...

Changing the helical propensity of a polypeptide sequence might be expected to affect the conformational properties of the denatured state of a protein. To test this hypothesis, alanines at positions 83 and 87 near the center of helix 3 of cytochrome c' from Rhodopseudomonas palustris were mutated to serine to decrease the stability of this helix. A set of 13 single histidine variants in the A83S/A87S background were prepared to permit assessment of the conformational properties of the denatured state using histidine-loop formation in 3 M guanidine hydrochloride...
