In this work, we developed a general Perturbation Theory and Machine Learning (PTML) method for data mining of proteomes, in order to discover new B-cell epitopes useful for vaccine design. The method predicts the epitope activity εq(cqj) of one query peptide (q-peptide) in a set of experimental query conditions (cqj). The method uses as input the sequence of the q-peptide. The method also uses as input information about the sequence and epitope activity εr(crj) of a peptide of reference (r-peptide) assayed on similar experimental conditions (crj)...

We present a new method of characterizing damage arising from α-recoil cascades in amorphous materials including glasses. The approach taken is topological, yielding information of atom connectivity and utilizing complete sets of orthogonal functions (spherical harmonics and Hermite functions) to compute order parameters. The utility of our new approach is demonstrated by first applying it to models of radiation damaged crystalline zircon, enabling validation against the standard defect counting method (Wigner-Seitz)...

The innate immune response to pathogenic challenge is a complex, multi-staged process involving thousands of genes. While numerous transcription factors that act as master regulators of this response have been identified, the temporal complexity of gene expression changes in response to pathogen-associated molecular pattern receptor stimulation strongly suggest that additional layers of regulation remain to be uncovered. The evolved pathogen response program in mammalian innate immune cells is understood to reflect a compromise between the probability of clearing the infection and the extent of tissue damage and inflammatory sequelae it causes...

Idiopathic epilepsy is characterized by generalized seizures with no apparent cause. One of its main problems is the lack of biomarkers to monitor the evolution of patients. The only tools they can use are limited to inspecting the amount of seizures during previous periods of time and assessing the existence of interictal discharges. As a result, there is a need for improving the tools to assist the diagnosis and follow up of these patients. The goal of the present study is to compare and find a way to differentiate between two groups of patients suffering from idiopathic epilepsy, one group that could be followed-up by means of specific electroencephalographic (EEG) signatures (intercritical activity present), and another one that could not due to the absence of these markers...

BACKGROUND: Quality anesthetic care is lacking in low- and middle-income countries (LMICs). Global health leaders call for perioperative capacity reports in limited-resource settings to guide improved health care initiatives. We describe a teaching hospital's resources and the national workforce and education in this LMIC capacity report. METHODS: A prospective observational study was conducted at Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana, during 4 weeks in August 2016...

To prepare new graduates with the knowledge, skills, and attitudes to engage in effective interprofessional collaboration (IPC) in practice, healthcare professional programmes need to ensure their curriculum provides opportunities for interprofessional education (IPE) and IPC. To strengthen IPE within an undergraduate curriculum and meet the professional requirements set out by regulatory bodies to prepare new graduate nurses to achieve IPC competencies, a curriculum initiative was developed to expand IPE across the four years of the Baccalaureate of Science in Nursing (BSN) programme...

Alexei A Kananenka, Dominika Zgid
We present a rigorous framework which combines single-particle Green's function theory with density functional theory based on a separation of electron-electron interactions into short- and long-range components. Short-range contribution to the total energy and exchange-correlation potential is provided by a density functional approximation, while the long-range contribution is calculated using an explicit many-body Green's function method. Such a hybrid results in a nonlocal, dynamic, and orbital-dependent exchange-correlation functional of a single-particle Green's function...

Wave functions restricted to electron-pair states are promising models to describe static/nondynamic electron correlation effects encountered, for instance, in bond-dissociation processes and transition-metal and actinide chemistry. To reach spectroscopic accuracy, however, the missing dynamic electron correlation effects that cannot be described by electron-pair states need to be included a posteriori. In this article, we extend the previously presented perturbation theory models with an Antisymmetric Product of 1-reference orbital Geminal (AP1roG) reference function that allow us to describe both static/nondynamic and dynamic electron correlation effects...

This study aimed at quantifying the residual amount of azoxystrobin in Swiss chard samples grown under greenhouse conditions at 2 different locations (Gwangju and Naju, Republic of Korea). Samples were extracted with acetonitrile, separated by salting out, and subjected to purification by using solid-phase extraction (SPE). The analyte was identified using liquid chromatography (LC)-ultraviolet detector (UVD). The linearity of the calibration range was excellent with coefficient of determination (R(2) ) =1...

We investigate online nonlinear regression and introduce novel regression structures based on the long short term memory (LSTM) networks. For the introduced structures, we also provide highly efficient and effective online training methods. To train these novel LSTM-based structures, we put the underlying architecture in a state space form and introduce highly efficient and effective particle filtering (PF)-based updates. We also provide stochastic gradient descent and extended Kalman filter-based updates. Our PF-based training method guarantees convergence to the optimal parameter estimation in the mean square error sense provided that we have a sufficient number of particles and satisfy certain technical conditions...

BACKGROUND AND PURPOSE: There is a paucity of data on persistence of secondary prevention medications among stroke survivors in resource-limited settings where stroke is on a rapid upward trajectory and its management severely challenged. To avert new cardiovascular events after stroke, preventive medications should be promptly instituted and used continuously. We report 1-year rates and determinants of persistent utilization of secondary prevention therapies after stroke in Ghana. METHODS: A retrospective observational study involving 418 stroke survivors enrolled into a Neurology clinic in a tertiary institution in central Ghana between January 2011 and December 2013...

Longjing Medial College, established in Longjing, Yanbian, China on September 12, 1945, existed for about 1 year and 6 months until it was renamed as the Medical Department of Dongbei Junzheng Daxue Jilin Fenxiao in April 1947. However, there are only few records and studies on Longjing Medical College in Yanbian as well as in Korea. In order to fill the gap, this study attempted to restore the history of Longjing Medical College built in Yanbian, China immediately after the liberation. In particular, it analyzed how and why the Longjing Medical College was founded and operated, and which relations the college had with the post-war medical educational institutions, focusing on the 'disconnection' and 'continuity' in the historical sense...

In vertebrates and invertebrates, oxytocin/vasopressin-like peptides modulate a variety of behaviors. The recent discovery of the gene and receptor sequences of inotocin, the insect ortholog of oxytocin/vasopressin, opens new opportunities for understanding the role of this peptide family in regulating behaviors in the most populated class of living animals. Ants live in highly organized colonies. Once a year, they produce future queens that soon leave the nest to mate and found new colonies. During the first months of their lives, ant queens display a sequence of behaviors ranging from copulation and social interactions to violent fighting...

The convergence of medical treatment that can extend life with written medical orders that make it possible to refuse such treatment brings the differential dynamics of contemporary end-of-life decision-making into sharp focus. Communication between families and clinicians can be confusing, uncertain and pressured when death is imminent. These situations create distress that ultimately influences the end-of-life experience for people who are dying and those who care for them. This paper presents the analysis of the decisional dynamics that emerge from the intersection of the patient-family-provider awareness that death is near with the presence or absence of documentation of expressed wishes for end-of-life care...

Αn approximate solution is presented for the prediction of air entrapment during tableting. Assuming weak coupling of the deformation of the solid phase, the flow of interstitial air and a set of reasonable additional geometric assumptions, the general problem is reduced to one dimension. Experimental values of air permeability through tablet specimens of commonly used pharmaceutical excipients were obtained using a 3D printed test cell outfitted to a powder rheometer. Using these values, combined with a numerical solution of the governing partial differential equation, parametric studies are presented that demonstrate the importance of permeability, compaction speed, tablet size, and punch-die tolerance on air entrapment...

Magnetic resonance elastography holds promise as a non-invasive, easy-to-use, in vivo biomarker for neurodegenerative diseases. Throughout the past decade, pigs have gained increased popularity as large animal models for human neurodegeneration. However, the volume of a pig brain is an order of magnitude smaller than the human brain, its skull is 40% thicker, and its head is about twice as big. This raises the question to which extent established vibration devices, actuation frequencies, and analysis tools for humans translate to large animal studies in pigs...

Rebecca A Waters, Angus Buchanan
Being 'person-centred' in the delivery of health and human services has become synonymous with quality care, and it is a core feature of policy reform in Australia and other Western countries. This research aimed to identify the uses, definitions and characteristics of the term 'person-centred' in the ageing, mental health and disability literature. A thematic analysis identified seven common core themes of person-centredness: honouring the person, being in relationship, facilitating participation and engagement, social inclusion/citizenship, experiencing compassionate love, being strengths/capacity focussed, and organisational characteristics...

The aim of the publication was to develop a practical guide for people, carers and health and social care professionals on how the research and evidence base on pressure ulcer prevention and management can be applied to those who remain seated for extended periods of time. This publication was developed at the request of the Tissue Viability Society in order to revise the original seating guidelines from 2008 as evidence and subsequent care has moved forward in relation to this area. Since 2008, the costs for the prevention and management of pressure ulcers have increased significantly and there is limited published advice from health and social care organisations on seating and preventing pressure ulcers...

INTRODUCTION: Code status discussions form an important part of advance care planning (ACP) as it enables physicians to respect the patient's wishes for end-of-life care. However, in some cases, code status discussions can be challenging causing the physician to go against the patient's wishes and the code of medical ethics. This is especially true in an emergency setting. In this paper, we will discuss three cases of advanced cancer patients, where code status discussions posed challenges to healthcare providers...

INTRODUCTION: Macrophage activation syndrome (MAS) is a life-threatening hyperinflammatory state mediated by uncontrolled cytokine storm and haemophagocytosis. Although rarely reported, MAS might occur in systemic lupus erythematosus (SLE), notably as an inaugural manifestation. Glucocorticoids (GCs) are the cornerstone of SLE therapy. However, in some cases high doses of GCs are required to achieve remission (i.e. glucocorticoid-resistance), leading to significant side effects. CASE REPORT: A 28-year-old Romani male was admitted to our hospital for polyarthralgia, polyserositis and fatigability...
