#1
Paul Murphy, Jeremy P Coe, Martin J Paterson
To perform spin-orbit coupling calculations on atoms and molecules, good zeroth-order wavefunctions are necessary. Here, we present the software development of the Monte Carlo Configuration Interaction (MCCI) method, to enable calculation of such properties, where MCCI iteratively constructs a multireference wavefunction using a stochastic procedure. In this initial work, we aim to establish the efficacy of this technique in predicting the splitting of otherwise degenerate energy levels on a range of atoms and small diatomic molecules...

REVIEW
Nicola Pirozzi, Antonella Stoppacciaro, Paolo Menè
Recently, a number of reports have described dominant C3 deposits in renal biopsies of patients with infection-related glomerulonephritis (GN). While acute post-infectious GN and membranoproliferative GN are commonly characterized by immune deposits containing C3 and/or C4, the absence of immunoglobulin (Ig) and/or immune complexes at light or electron microscopy is a rather unusual observation. Dominant C3 deposition is believed to result from the alternative pathway of complement activation via the C3bBb "tickover" convertase...

Perturbations delivered to the upper limbs elicit reflexive responses in stretched muscle at short- (M1: 25-50 ms) and long- (M2: 50-100 ms) latencies. When presented in a simple reaction time (RT) task, the perturbation can also elicit a preprogrammed voluntary response at a latency (< 100 ms) that overlaps the M2 response. This early appearance of the voluntary response following a proprioceptive stimulus causing muscle stretch is called a triggered reaction. Recent work has demonstrated that a perturbation also elicits activity in sternocleidomastoid (SCM) over a time-course consistent with the startle response and it was, therefore, proposed that the StartReact effect underlies triggered reactions (Ravichandran et al...

Expansin act by loosening hydrogen bonds in densely packed polysaccharides. This work characterizes the biological functions of expansin in the gelling and degradation of algal polysaccharides. In this study, the bacterial expansin BpEX from Bacillus pumilus was fused with the dockerin module of a cellulosome system for assembly with agarolytic complexes. The assembly of chimeric expansin caused an indicative enhancement in agarase activity. The enzymatic activities on agar substrate and natural biomass were 3...

Alain Barrelle, J-P Luauté
The delusional misidentification syndromes (DMS) are a group of disorders, characterized by patients mistaking the identity of people they know, although they recognize them physically. The term DMS is an umbrella term which may cover disorders whose definition extends to objects other than people, such as animals, places, or familiar material objects. The most common and best known DMS is Capgras syndrome. In this disorder, the misidentification leads to the delusional conviction that a close friend or relative has been replaced by an identical - or almost identical - "double," whose original has disappeared...

Brook A L Perry, Stephanie A Mercer, Sophie C Barnett, Jungah Lee, John C Dalrymple-Alford
The anterior thalamic nuclei (ATN), mammillary bodies and their interconnecting fiber tract, the mammillothalamic tract (MTT), are important components of an extended hippocampal circuit for episodic memory. In humans, damage to the MTT or ATN in many disorders is associated with severe anterograde amnesia and it is assumed that their influence on memory is functionally equivalent. The relative influence of these two structures on memory has not, however, been assessed explicitly. Here, a direct comparison found that only ATN lesions impaired spatial reference memory in rats...

People with serious mental illness (service users) have needs related to sexual health and sexuality, yet these have been poorly addressed in mental health services. In the present study, we report the current practice of mental health professionals in relation to sexual health. Focus groups conducted in two mental health trusts explored routine practice in relation to discussing, assessing, and planning care in relation to sexual health. A thematic analysis identified seven themes: (i) sexual health provision is a complex issue; (ii) mental health staff are aware of sexual health needs; (iii) current provision regarding sexual health is 'neglected'; (iv) barriers to sexual health provision; (v) enabling a discussion around sexual health; (vi) sexual health provision is a role for mental health professionals; and (vii) training needs...

Fecal contamination of water sources is an important water quality issue for agricultural irrigation ponds. Escherichia coli concentrations are commonly used to evaluate recreational and irrigation water quality. We hypothesized that there may exist temporally stable spatial patterns of E. coli concentrations across ponds meaning that some areas mostly have higher and other have mostly lower than average concentrations of E. coli To test this hypothesis, we sampled two irrigation ponds in Maryland in nodes of spatial grids biweekly during the summer of 2016...

Mercury (Hg), one of the most toxic and widely distributed heavy metals, has a high affinity for thiol groups. Thiol groups reduce and sequester Hg. Therefore, low molecular weight and protein thiols may be important cell components used in Hg resistance. To date, the role of low molecular weight thiols in Hg-detoxification remains understudied. The mercury resistance (mer) operon of Thermus thermophilus suggests an evolutionary link between Hg(II) resistance and low molecular weight thiol metabolism. This mer operon encodes for an enzyme involved in methionine biosynthesis, Oah...

In this commentary, I respond to the special section in Health&Place (vol. 46) on "Exercise and environment: new qualitative work to link popular practice and public health" edited by Hitchings and Latham. I argue that if qualitative research is to effectively inform public health policy and practice it cannot ignore the fact that physical activity participation is inequitable. Without building in a critical equity lens, geographers risk perpetuating the "inequality paradox"-that is, the potential for population health interventions to inadvertently exacerbate health inequalities...

Contributory risk factors to premature coronary artery disease (CAD) in premenopausal women are poorly understood and data on this subset of women is lacking. There is growing evidence that the process of inflammation is a part of the atherosclerotic process. Mechanistic insights from animal work suggest that the profile of circulating cytokines reflects both endothelial integrity and the presence of immune and progenitor cells. Significant differences in pro- and anti-inflammatory cytokine concentrations between patients with and without CAD exist...

OBJECTIVES: Although there is substantial evidence that psychological factors play an important role in the onset and course of cardiovascular disease (CVD), less is known about their combined effect and the pathways by which they affect cardiovascular health. The present work aimed to prospectively explore the effects of depression and anxiety on the 10-year CVD incidence, in relation to other lifestyle determinants, as linking factors in the context of the ATTICA study. Study design/Main outcome measures: The ATTICA study is a population-based, health and nutrition prospective cohort study (2002-2012), during which 853 middle-aged participants without a history of CVD [453 men (aged 45±13years) and 400 women (aged 44±18years)], underwent psychological evaluations at enrollment...

The analysis of flotation and adsorption of mixed collectors on oxide and silicate minerals is of great importance for both industrial applications and theoretical research. Over the past years, significant progress has been achieved in understanding the adsorption of single collectors in micelles as well as at interfaces. By contrast, the self-assembly of mixed collectors at liquid/air and solid/liquid interfaces remains a developing area as a result of the complexity of the mixed systems involved and the limited availability of suitable analytical techniques...

BACKGROUND: Acute rheumatic fever (ARF) rates have declined to near zero in nearly all developed countries. However, in New Zealand rates have not declined since the 1980s. Further, ARF diagnoses in New Zealand are inequitably distributed--occurring almost exclusively in Māori (the indigenous population) and Pacific children--with very low rates in the majority New Zealand European population. With ARF diagnosis, secondary prophylaxis is key to prevent recurrence. The purpose of this study was to identify the perceived enablers and barriers to secondary recurrence prophylaxis following ARF for Māori patients aged 14-21...
