R A Crane, D J Sapsford
Nanoscale zerovalent iron (nZVI) has been investigated for the selective formation of Cu nanoparticles from acid mine drainage (AMD) taken from a legacy mine site in the UK. Batch experiments were conducted containing unbuffered (pH 2.67 at t = 0) and pH buffered (pH < 3.1) AMD which were exposed to nZVI at 0.1-2.0 g/L. Results demonstrate that nZVI is selective for Cu, Cd and Al removal (>99.9% removal of all metals within 1 h when nZVI ≥ 1.0 g/L) from unbuffered AMD despite the coexistent of numerous other metals in the AMD, namely: Na, Ca, Mg, K, Mn and Zn...

Advance directives such as living wills and health care powers of attorney are important documents that offer patients ways to avoid unwanted care when they are unable to express their wishes. Although health care professionals have increased focus on advance care planning in recent years, approximately two thirds of American adults do not have advance medical directives. In addition, 90% of individuals believe that talking to loved ones about end-of-life wishes is important, but only 27% have done so. It is important for nurses to understand the complex factors that influence how individuals make health care decisions and identify ways to encourage conversations with family, friends, and health care providers to help clarify patients' wishes for endof-life care...

Climate change projections anticipate increased frequency and intensity of drought stress but grassland responses to severe droughts and their potential to recover are poorly understood. In many grasslands, high land-use intensity has enhanced productivity and promoted resource-acquisitive species at the expense of resource-conservative ones. Such changes in plant functional composition could affect the resistance to drought and the recovery after drought of grassland ecosystems with consequences for feed productivity resilience and environmental stewardship...

After abandonment of agricultural fields, some grassland plant species colonize these sites with a frequency equivalent to dry grasslands (generalists) while others are missing or underrepresented in abandoned fields (specialists). We aimed to understand the inability of specialists to spread on abandoned fields by exploring whether performance of generalists and specialists depended on soil abiotic and/or biotic legacy. We performed a greenhouse experiment with 12 species, six specialists and six generalists...

Nathalie Pilard
Intuition is central in the work, practice, and philosophical legacy of C. G. Jung. In this paper, I will first discuss the importance of intuition for Jung in the paradigm usually designated the 'paranormal'. Jung was attracted to intuition as an extra-ordinary gift or function in the traditional sense, and this is considered here in relation to his 1896-1899 Zofingia Lectures and 1902 On the Psychology and Pathology of So-called Occult Phenomena: A Psychiatric Study. A significant development then occurred in 1913, when esotericist intuitions were turned toward psychological use with Jung's Red Book...

BACKGROUND: In a highly technical civilization like ours, in which the interest in human communication transcends academic barriers and clinical practice, it seems necessary to look back to Ruesch's work in psychiatry. The main reason of it rests upon the idea that he was one of the few truly outstanding clinicians, researchers, and theoretical in the field of normal and abnormal communication. In fact, he did not only present a wealth of observational and clinical data; more importantly, he used these data to formulate creative hypotheses about the conflict between man and other human beings...

Currently one small, native population of the culturally and ecologically important Lahontan cutthroat trout (Oncorhynchus clarkii henshawi, LCT, Federally listed) remains in the Truckee River watershed of northwestern Nevada and northeastern California. The majority of populations in this watershed were extirpated in the 1940s due to invasive species, overharvest, anthropogenic water consumption and changing precipitation regimes. In 1977, a population of cutthroat trout discovered in the Pilot Peak Mountains in the Bonneville basin of Utah, was putatively identified as the extirpated LCT lacustrine lineage native to Pyramid Lake in the Truckee River basin based on morphological and meristic characters...

After the creation of the Academy of Medical Sciences of Ukraine in 1993 the Research Center for Radiation Medicine was among the first institutions to join the Academy (fig. 1). Estab lishing the Academy was among the first steps of the independent Ukrainian government and aimed to provide a high level health care for population. It was extremely needed for the minimization of Chornobyl medical consequences. This choice was related to a growing recognition of the scientific research in fulfilling the Сenter's mission - study of the effects of low dose radiation on human body and radiation protection of the exposed population...

BACKGROUND: Patients who have pacemakers or defibrillators are often denied the opportunity to undergo magnetic resonance imaging (MRI) because of safety concerns, unless the devices meet certain criteria specified by the Food and Drug Administration (termed "MRI-conditional" devices). METHODS: We performed a prospective, nonrandomized study to assess the safety of MRI at a magnetic field strength of 1.5 Tesla in 1509 patients who had a pacemaker (58%) or an implantable cardioverter-defibrillator (42%) that was not considered to be MRI-conditional (termed a "legacy" device)...

University level of Pathophysiology research and teaching in Croatia had started with the third year of Medical School of Zagreb in academic year 1919./20. Ever since, despite historical changes of the main university stake holder, the state of Croatia, Department of Pathophysiology development progressed and has made visible academic achievements, with a broader effect in medical community. The first 95 years of academic tradition and major achievements are shortly described in this paper. Professor Miroslav Mikuličić envisioned Pathophysiology in close relations with Pharmacology and made the pioneering steps of establishing the "double" department at Šalata...

In the 1920s and 1930s, doctors stationed in the Middle East and North Africa debated whether bejel, a form of endemic syphilis, was an Arab version of syphilis, or a separate disease altogether. Using their clinical experience in the region, they tried to weave this unfamiliar phenomenon into a civilizational narrative, which placed European civilization at the top of a hierarchy. The assumption was that there was something inherent to Islamic societies and their hygienic habits that accounted for this difference...

BACKGROUND: Knowledge of catalytic residues can play an essential role in elucidating mechanistic details of an enzyme. However, experimental identification of catalytic residues is a tedious and time-consuming task, which can be expedited by computational predictions. Despite significant development in active-site prediction methods, one of the remaining issues is ranked positions of putative catalytic residues among all ranked residues. In order to improve ranking of catalytic residues and their prediction accuracy, we have developed a meta-approach based method CSmetaPred...

December 2015 and March 2016 issues of the American Journal of Psychiatry contain a debate focusing on the legacy of Emil Kraepelin, widely considered one of the founders if not the iconic founder of modern scientific psychiatry. The authors, Eric J. Engstrom and Kenneth S. Kendler, challenge the so-called neo-Kraepelinian view of Kraepelin and argue that the true, historical Kraepelin was far more inclined towards scientific psychology, less reductionist and brain-centric, and more skeptical nosologically than his later followers apparently believe...

Lead battery recycling is a growing hazardous industry throughout Africa. We investigated potential soil contamination inside and outside formal sector recycling plants in seven countries. We collected 118 soil samples at 15 recycling plants and one battery manufacturing site and analyzed them for total lead. Lead levels in soils ranged from < 40-140,000mg/kg. Overall mean lead concentrations were ~23,200mg/kg but, average lead levels were 22-fold greater for soil samples from inside plant sites than from those collected outside these facilities...

OBJECTIVE: Adult patients with psoriatic arthritis are at increased risk for obesity and metabolic syndrome, but data regarding adiposity in children with juvenile psoriatic arthritis (JPsA) are limited. Our study assessed adiposity in children with JPsA in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) registry. METHODS: Patients with JPsA in the CARRA registry were divided into nonoverweight and overweight groups using recommendations from the US Centers for Disease Control, and differences in demographic and clinical characteristics between groups at baseline and after 1-year followup were assessed using chi-square test, Fisher's exact test, T test, or Mann-Whitney U test, as appropriate...

Tundra regions are projected to warm rapidly during the coming decades. The tundra biome holds the largest terrestrial carbon pool, largely contained in frozen permafrost soils. With warming, these permafrost soils may thaw and become available for microbial decomposition, potentially providing a positive feedback to global warming. Warming may directly stimulate microbial metabolism but may also indirectly stimulate organic matter turnover through increased plant productivity by soil priming from root exudates and accelerated litter turnover rates...

In the United States, breast cancer is the second leading cause of cancer death in women. Over the past 20 years, breast cancer incidence and mortality rates increased rapidly in developing regions. We aimed to identify the gene mutation patterns that associated with the clinical patterns, including survival status, histo-pathological classes and so forth, of breast cancer. We retrieved 1098 cases of the clinical information, and level-3 legacy data of mRNA expression level, protein expression data and mutation files from GDC data portal...

Background: This study aims to characterize the role of county-specific legacy of slavery in patterning temporal (i.e., 1968-2014), and geographic (i.e., Southern counties) declines in heart disease mortality. In this context, the U.S. has witnessed dramatic declines in heart disease mortality since the 1960's, which have benefitted place and race groups unevenly, with slower declines in the South, especially for the Black population. Methods: Age-adjusted race- and county-specific mortality rates from 1968-2014 for all diseases of the heart were calculated for all Southern U...

The World Health Organisation guidance recommends breastfeeding peer support (BFPS) as part of a strategy to improve breastfeeding rates. In the UK, BFPS is supported by National Institute for Health and Care Excellence guidance and a variety of models are in use. The experimental evidence for BFPS in developed countries is mixed and traditional methods of systematic review are ill-equipped to explore heterogeneity, complexity, and context influences on effectiveness. This review aimed to enhance learning from the experimental evidence base for one-to-one BFPS intervention...

The branches of medicine responsible for the care of victims of different types of injuries were born as a result of the urgent need to save lives during the wars. In Mexico, one of the first hospitals developed for the care of injured patients was the Central Hospital of the Mexican Red Cross. The aim of this article is to pay tribute to the first service for the care of patients with chest trauma, founded in 1954, its founders and those who have continued with their work: Dr. Pedro Garza Alegría, Dr. Octavio Rivas Solís Dr...
