Bivalve molluscs feeding on toxigenic Pseudo-nitzschia spp. are the main vector of domoic acid (DA) to humans. Although different oyster species rarely exceed the internationally adopted regulatory level for shellfish harvesting closures (20 μg g–1), these are often applied to all bivalve species in an affected area. This study examines the influence of diet composition and Pseudo-nitzschia mul...

BACKGROUND Patients with Hodgkin's disease (HD) and intermediate or high-grade non-Hodgkin's lymphoma (NHL) who fail to achieve a complete remission (CR) with standard induction therapy have a poor prognosis with conventional-dose salvage therapy alone. We examined the role of subsequent intensive therapy and autologous bone marrow transplantation (ABMT) in patients who demonstrated a response ...

OBJECTIVES In Denmark, the local and regional health authorities share responsibility for cardiac rehabilitation (CR). The objective was to assess effectiveness of CR across sectors coordinated by a nurse case manager (NCM). DESIGN A one-year follow-up study. SETTING A CR programme (GoHeart) was evaluated in a cohort at Lillebaelt Hospital Vejle, DK from 2010 to 2011. PARTICIPANTS Consecu...

There is long research interest in electron-induced reactions of halogenated molecules. It has been two decades since the cosmic-ray (CR) driven reaction (CRE) mechanism for ozone hole formation was proposed. The derived CRE equation with stratospheric equivalent chlorine level and CR intensity as only variables well reproduced observed data O3 temperatures over past 40 years. predictions 11-ye...

Earlier we reported, in this journal, that the pits generated in CR-39 detectors during Pd/D co-deposition experiments are consistent with those observed for pits that are of a nuclear origin. Recently, that interpretation has been challenged. In this communication, additional experimental data and further analysis of our earlier results are provided that support our original conclusions. PACS....

Introduction: This study was conducted to measure the gamma emitters (e.g., uranium-238 [238U], thorium-232 [232Th], and potassium-40[40K]) and alpha emitters (e.g., radon-222 [222Rn] and radium), and also to evaluate the radiation hazard indices of radionuclides in parenteral nutrition samples utilized in the hospitals of Iraq. Material and Methods: The measurements were accomplished using ga...

We report on the synthesis of computationally predicted out-of-plane chemically ordered transition metal borides labeled o-MAB phases, Ta4M″SiB2 (M″ = V, Cr), and a structurally equivalent disordered solid solution MAB phase Ta4MoSiB2. The boride phases were prepared using solid-state reaction sintering constituting elements. High-resolution scanning transmission electron microscopy along with ...

background: a pot experiment was conducted to determine the toxic effects of some heavy metals on the plant growth and seed yield of maize (zea mays l.). materials and metheds: heavy metals mn, pb, cd, cr and co individually and in combinations were added as chloride salts in solutions to the pots before sowing. the test plants for were harvested after 80 days of germination and evaluated for n...
