Effect of extraction pH on heat-induced aggregation, gelation and microstructure of protein isolate from quinoa (Chenopodium quinoa Willd).

The aim of this study was to determine the influence of extraction pH on heat-induced aggregation, gelation and microstructure of suspensions of protein isolates extracted from quinoa (Chenopodium quinoa Willd). Quinoa seed protein was extracted by alkaline treatment at various pH values (pH 8 (E8), 9 (E9), 10 (E10) and 11 (E11)), followed by acid precipitation. The obtained protein isolates were freeze dried.

Choosing Words Wisely in Communication With Patients With Heart Failure and Families.

The complex and often unpredictable course of heart failure (HF) provides many opportunities for communication between clinicians and patients about important subjects as advance care planning, disease state education, therapeutic options and limitations, and end-of-life care. Studies of patients with HF demonstrate that, when engaging in such complex communication, specific language matters in patient experience and in shared decision-making with providers. To date, clinical reports have outlined useful frameworks for communication with patients with HF but have not yet broached specific language crucial to furthering whole person care, particularly in the complex and emotional realm of advancing disease and transitions to end-of-life care.

Investigating the widespread introduction of a tropical marine fouling species.

Little is known about the number and rate of introductions into terrestrial and marine tropical regions, and if introduction patterns and processes differ from temperate latitudes. Botryllid ascidians (marine invertebrate chordates) are an interesting group to study such introduction differences because several congeners have established populations across latitudes. While temperate botryllid invasions have been repeatedly highlighted, the global spread of tropical Botrylloides nigrum (Herdman, 1886) has been largely ignored.

Mini-review: Assessing the drivers of ship biofouling management--aligning industry and biosecurity goals.

Biofouling exerts a frictional and cost penalty on ships and is a direct cause of invasion by marine species. These negative consequences provide a unifying purpose for the maritime industry and biosecurity managers to prevent biofouling accumulation and transfer, but important gaps exist between these sectors. This mini-review examines the approach to assessments of ship biofouling among sectors (industry, biosecurity and marine science) and the implications for existing and emerging management of biofouling.

The new Andean jumping spider genus Urupuyu and its placement within a revised classification of the Amycoida (Araneae: Salticidae).

Urupuyu gen. nov. is described for three new species of small black jumping spiders from the cloud forests of Ecuador: Urupuyu antisana sp.

The jumping spider genus Thiodina Simon, 1900 reinterpreted, and revalidation of Colonus F.O.P-Cambridge, 1901 and Nilakantha Peckham & Peckham, 1901 (Araneae: Salticidae: Amycoida).

In this paper we call attention to the identity of the type species of Thiodina Simon, 1900, T. nicoleti Roewer, 1951. When Simon proposed the genus, he characterized it based on morphological features found in species he described, but not found in the type species he designated, and whose type specimens, apparently, he had not examined.

Finding an apprenticeship: hidden curriculum and social consequences.

In Switzerland, the majority of students are oriented toward professional training after compulsory schooling. At this stage, one of the biggest challenges for them is to find an apprenticeship position. Matching supply and demand is a complex process that not only excludes some students from having direct access to professional training but also forces them to make early choices regarding their future sector of employment.

Amplicon-Based Pyrosequencing Reveals High Diversity of Protistan Parasites in Ships' Ballast Water: Implications for Biogeography and Infectious Diseases.

Ships' ballast water (BW) commonly moves macroorganisms and microorganisms across the world's oceans and along coasts; however, the majority of these microbial transfers have gone undetected. We applied high-throughput sequencing methods to identify microbial eukaryotes, specifically emphasizing the protistan parasites, in ships' BW collected from vessels calling to the Chesapeake Bay (Virginia and Maryland, USA) from European and Eastern Canadian ports. We utilized tagged-amplicon 454 pyrosequencing with two general primer sets, amplifying either the V4 or V9 domain of the small subunit (SSU) of the ribosomal RNA (rRNA) gene complex, from total DNA extracted from water samples collected from the ballast tanks of bulk cargo vessels.

Norharmane rhenium(I) polypyridyl complexes: synthesis, structural and spectroscopic characterization.

Two novel Re(i) complexes with the general formula fac-[Re(CO)3(L)(nHo)]CF3SO3, where L = 2,2'-bipyridine (bpy) or 1,10 phenanthroline (phen) and nHo (9H-pyrido[3,4-b]indole; norharmane) have been synthesized. The Re(i)-nHo complexes were characterized by structural X-ray diffraction, (1)H and (13)C NMR, UV-vis absorption and FT-IR spectroscopy, and by a combination of two mass spectrometry techniques, namely ESI-MS and UV-MALDI-MS. All characterizations showed that nHo is coordinated to the metal atom by the pyridine nitrogen of the molecule.

The Inhibitory Activity of Plants from Central Argentina on p-Hydroxyphenylpyruvate Dioxygenase. Isolation and Mechanism of Inhibition of a Flavanone from Flourensia oolepis.

The enzyme 4-hydroxyphenylpyruvate dioxygenase catalyzes the second step in the tyrosine degradation pathway. In mammals, this enzyme is the molecular target of drugs used for the treatment of metabolic disorders associated with defects in the tyrosine catabolism, mainly the fatal hereditary disease tyrosinemia type 1. This study evaluated the inhibitory effect of 91 extracts on 4-hydroxyphenylpyruvate dioxygenase from mostly native plants from central Argentina.

Description of four new species of Hypaeus Simon and redescription of H. taczanowskii Mello-Leitão (Araneae: Salticidae: Amycinae).

Four new species of Hypaeus Simon are described from the Brazilian Amazon, all based on both sexes: H. tridactylus sp. nov.

Invasion Expansion: Time since introduction best predicts global ranges of marine invaders.

Strategies for managing biological invasions are often based on the premise that characteristics of invading species and the invaded environment are key predictors of the invader's distribution. Yet, for either biological traits or environmental characteristics to explain distribution, adequate time must have elapsed for species to spread to all potential habitats. We compiled and analyzed a database of natural history and ecological traits of 138 coastal marine invertebrate species, the environmental conditions at sites to which they have been introduced, and their date of first introduction.

Combination therapy in pulmonary arterial hypertension: is this the new standard of care?

Pulmonary arterial hypertension (PAH) is a rare, progressive, and potentially fatal cardiopulmonary syndrome that imposes a significant burden on patients in terms of morbidity and mortality, and on managed care organizations in terms of resource utilization. The majority of PAH-approved therapies are high-touch, high-management, high-cost treatments dispensed through specialty pharmacies. Current treatment guidelines recommend combination therapy for patients who show inadequate clinical response or who deteriorate on monotherapy.

Associations among Depression Symptoms with Alcohol and Smoking Tobacco Use in Adult Patients with Congenital Heart Disease.

Background: Adult congenital heart disease (ACHD) patients have high rates of untreated depression and anxiety disorders. We evaluated associations among self-reported depression symptoms and alcohol/smoking tobacco use.

Methods: From 2009 to 2013, 202 ACHD patients (45% male) completed questionnaires on depressive symptoms, anxiety symptoms, and substance use as part of routine clinical care.

Regional Variation in Parasite Species Richness and Abundance in the Introduced Range of the Invasive Lionfish, Pterois volitans.

Parasites can play an important role in biological invasions. While introduced species often lose parasites from their native range, they can also accumulate novel parasites in their new range. The accumulation of parasites by introduced species likely varies spatially, and more parasites may shift to new hosts where parasite diversity is high.

Secondary abdominal compartment syndrome after complicated traumatic lower extremity vascular injuries.

Introduction: Secondary abdominal compartment syndrome (ACS) can occur in trauma patients without abdominal injuries. Surgical management of patients presenting with secondary ACS after isolated traumatic lower extremity vascular injury (LEVI) continues to evolve, and associated outcomes remain unknown.

Methods: From January 2006 to September 2011, 191 adult trauma patients presented to the Ryder Trauma Center, an urban level I trauma center in Miami, Florida with traumatic LEVIs.

Classification of non-indigenous species based on their impacts: considerations for application in marine management.

Assessment of the ecological and economic/societal impacts of the introduction of non-indigenous species (NIS) is one of the primary focus areas of bioinvasion science in terrestrial and aquatic environments, and is considered essential to management. A classification system of NIS, based on the magnitude of their environmental impacts, was recently proposed to assist management. Here, we consider the potential application of this classification scheme to the marine environment, and offer a complementary framework focussing on value sets in order to explicitly address marine management concerns.

Taraxacum officinale and related species-An ethnopharmacological review and its potential as a commercial medicinal plant.

Ethnopharmacological Relevance: Dandelion (Taraxacum spec) is a wild plant that has been used for centuries as a traditional medicine in the relief and treatment of several diseases. This use is due to the presence of sesquiterpenes, saponins, phenolic compounds, flavonoids, and sugars, among others, found in the organs of the plant.

Aim Of The Study: The aim of this work is to provide a current review of developments and trends in research on the Taraxacum genus, with a focus on traditional uses and pharmacological properties.

Metal release from contaminated estuarine sediment under pH changes in the marine environment.

The contaminant release from estuarine sediment due to pH changes was investigated using a modified CEN/TS 14429 pH-dependence leaching test. The test is performed in the range of pH values of 0-14 using deionised water and seawater as leaching solutions. The experimental conditions mimic different circumstances of the marine environment due to the global acidification, carbon dioxide (CO2) leakages from carbon capture and sequestration technologies, and accidental chemical spills in seawater.

Impaired exercise capacity following atrial septal defect closure: an invasive study of the right heart and pulmonary circulation.

Patients with early repair of an isolated atrial septal defect (ASD) are expected to have unremarkable right ventricular (RV) and pulmonary circulation physiology. Some studies, however, suggest persistent functional impairment. We aimed to examine the role of abnormal RV and pulmonary vascular response to exercise in patients who had undergone ASD closure.
