OBJECTIVES: To determine the effect of iterative refinement of standard ordering protocols on test utilization and results for bone marrow biopsy specimens. METHODS: Eighteen months of test utilization and result data were used to revise the protocols that determine cytogenetic and molecular test selection on bone marrow specimens and then compared with data obtained following protocol revision. RESULTS: Revision of protocols resulted in reduction in total tests and associated charges, due to a decrease in tests both concordant and discordant with the protocols...

A series of new Lycopodium alkaloids, namely 1-epi-malycorin A (1), 1-epi-17S-hydroxymalycorin A (2), 6α-hydroxyphlegmariurine A (3), 2S,4R-dihydroxyfawcettimine (4), and 16-hydroxylycodine (5), together with 24 known ones, have been isolated from the club moss Phlegmariurus henryi. The structures of the new compounds were determined by extensive spectroscopic analysis, including 1D and 2D NMR, as well as X-ray crystallographic analysis. Among them, the absolute configurations of 1, 2, and 4 and the structure of 3 were confirmed on the basis of the single-crystal X-ray crystallographic analysis...

Considerable scope exists to vary the physical and chemical properties of nanoparticles, with subsequent impact on biological interactions; however, no accelerated process to access large nanoparticle material space is currently available, hampering the development of new nanomedicines. In particular, no clinically available nanotherapies exist for HIV populations and conventional paediatric HIV medicines are poorly available; one current paediatric formulation utilizes high ethanol concentrations to solubilize lopinavir, a poorly soluble antiretroviral...

Oil extraction and development activities in the Athabasca Oil Sands Region of northern Alberta, Canada release NOx, SOx, and NHx to the atmosphere, ultimately resulting in increasing N and S inputs to surrounding ecosystems through atmospheric deposition. Peatlands are a major feature of the northern Alberta landscape, with bogs covering 6-10% of the land area, and fens covering 21-53%. Bulk deposition of NH4+-N, NO3--N, total inorganic N (TIN), and SO42--S, was quantified using ion exchange resin collectors deployed at 23 locations, over 1-6 years, reveal maximum N and S deposition of 9...

Here we present, to the best of our knowledge, the first case of a paraneoplastic Cushing's syndrome (hypercortisolism) resulting from treatment-related neuroendocrine prostate cancer - a highly aggressive and difficult disease to treat. A 51-year-old man was started on androgen deprivation therapy after presenting with metastatic prostate cancer, characterized by diffuse osseous metastasis. Shortly thereafter, he developed progressive disease with biopsy proven neuroendocrine prostate cancer as well as symptoms of increased skin pigmentation, hypokalemia, hypertension, hyperglycemia and profound weakness, consistent with ectopic Cushing's syndrome...

PREMISE OF THE STUDY: Resource allocation is difficult to characterize in plants because of the challenges of quantifying gametes and propagules. We surveyed six sympatric, unisexual species in the family Calymperaceae (Bryophyta) to test for trade-offs in prezygotic sexual and asexual expression and density-dependent survivorship of female gametangia. METHODS: We tallied gametangial and asexual propagule output for 1820 shoots from 17 populations of six species at monthly intervals during one year (2010-2011) in a central Amazonian forest...

Scopelophila ligulata is known to be a Fe-hyperaccumulator moss; however, its mechanism of accumulation and the effects of Fe on pigments remain unclear. To clarify the effects, we measured its metal and pigment concentrations. The Fe concentration in S. ligulata was 10-61 times higher than that in normal mosses, confirming that the moss is a Fe-hyperaccumulator. The black samples of S. ligulata had the highest Fe concentration (2.9 wt%) and the second in the order of decreasing Fe concentration (2.2 wt%), which explains their color and indicates that the excess amount of Fe is distributed through the plant body...

In tundra ecosystems, bryophytes influence soil processes directly and indirectly through interactions with overstory shrub species. We experimentally manipulated moss cover and measured seasonal soil properties and processes under two species of deciduous shrubs with contrasting canopy structures, Salix planifolia pulchra and Betula glandulosa-nana complex. Soil properties (seasonal temperature, moisture and C:N ratios) and processes (seasonal litter decomposition and soil respiration) were measured over twelve months...

The chloroplast (cp) genome is organized as nucleoids that are dispersed throughout the cp stroma. Previously, a cp homolog of bacterial recombinase RecA (cpRECA) was shown to be involved in maintenance of cp genome integrity by repairing damaged cpDNA and by suppressing aberrant recombination between short dispersed repeats (SDRs) in the moss Physcomitrella patens. Here, overexpression and knockdown analysis of cpRECA in the green alga Chlamydomonas reinhardtii revealed that cpRECA was involved in cp nucleoid dynamics as well as having a role in maintaining cp genome integrity...

Monoclonal antibodies are a potent therapeutic approach for relapsing-remitting multiple sclerosis. This group of medications comprises diverse mechanisms of action resulting in both shared and unique adverse effects. Areas covered: The major trials and safety profiles of natalizumab, alemtuzumab, daclizumab, rituximab, and ocrelizumab are discussed. While each drug has a unique safety profile, one of the potential safety concerns for all of these drugs is infection, including for some progressive multifocal leukoencephalopathy...

Renal denervation (RDN) was reported as a novel exciting treatment for resistant hypertension in 2009. An initial randomized trial supported its efficacy and the technique gained rapid acceptance across the globe. However, a subsequent large blinded, sham arm randomized trial conducted in the USA (to gain Food and Drug Administration approval) failed to achieve its primary efficacy end point in reducing office blood pressure at 6 months. Published in 2014 this trial received both widespread praise and criticism...

Clostridium difficile (CD) is an anaerobic, spore-forming bacillus that is responsible for a spectrum of gastrointestinal illness ranging from asymptomatic carriage to toxic megacolon and death. The prevalence of CD infection is increasing in both hospitalized and community-based inflammatory bowel disease populations. Standard antibiotic therapy fails to cure or prevent recurrence in more than 50% of patients, thus increasing the need for alternative therapies. Recently, fecal microbiota transplantation has received renewed attention as a therapy for refractory or recurrent CD infection...

BACKGROUND: In addition to reducing Haemophilus influenzae type b (Hib) disease in vaccinated individuals, the Hib conjugate vaccine (HibCV) has indirect effects; it reduces Hib disease in unvaccinated individuals by decreasing carriage. Human immunodeficiency virus (HIV)-infected children are at increased risk for Hib disease and live in families where multiple members may have HIV. The aim of this study is to look at the impact of 2 doses of the HibCV on nasopharyngeal carriage of Hib in HIV-infected Indian children (2-15 years) and the indirect impact on carriage in their parents...

BACKGROUND AND AIMS: Lecturers often present entertaining videos, or organize a variety of amusing demonstrations, to foster student engagement or to encourage critical analysis. Magic tricks, in particular, have been shown to activate neural circuits that underpin motivation or problem-solving and, therefore, could be beneficial during lectures. Nevertheless, we hypothesize that, unless the method that underpins these tricks is revealed, students may ruminate over possible explanations, distracting attention from the lecture material...

The neuroactive steroid (NAS) tetrahydrodeoxycorticosterone (THDOC) increases protein kinase C (PKC) mediated phosphorylation of extrasynaptic GABAA receptor (GABAAR) subunits leading to increased surface expression of α4/β3 subunit-containing extrasynaptic GABAARs, leading to a sustained increase in GABAAR tonic current density. Whether other naturally occurring and synthetic NASs share both an allosteric and metabotropic action on GABAARs is unknown. Here, we examine the allosteric and metabotropic properties of allopregnanolone (ALLO), and synthetic NASs SGE-516 and ganaxolone...

A 72-year-old woman with ulcerative colitis was referred to our hospital because of refractory diarrhea. Although she had been treated with prednisolone 12.5 mg/day and mesalazine suppositories 1 g/day, her watery diarrhea persisted. Colonoscopy was undergone 30 days after she started administration of mesalazine suppositories, and showed granularity of the mucosa with little erythematous appearance in the entire colon with endoscopic Mayo score 1. Double-contrast small-bowel radiography showed a rough mucosal surface in the terminal ileum...

INTRODUCTION: Epilepsy is a common neurological condition. Seizure diary reports and patient- or caregiver-reported seizure counts are often inaccurate and underestimated. Many caregivers express stress and anxiety about the patient with epilepsy having seizures when they are not present. Therefore, a need exists for the ability to recognize and/or detect a seizure in the home setting. However, few studies have inquired on detection device features that are important to patients and their caregivers...
