Abstract
In clinical treatments of a class of tumors, e.g. skin tumors, the drug uptake of tumor tissue is helped by means of a pulsed electric field, which permeabilizes the cell membranes. This technique, which is called electroporation, exploits the conductivity of the tissues: however, the tumor tissue could be characterized by inhomogeneous areas, eventually causing a non-uniform distribution of current. In this paper, the authors propose a field model to predict the effect of tissue inhomogeneity, which can affect the current density distribution. In particular, finite-element simulations, considering non-linear conductivity against field relationship, are developed. Measurements on a set of samples subject to controlled inhomogeneity make it possible to assess the numerical model in view of identifying the equivalent resistance between pairs of electrodes.
Modelling of magnetostriction of transformer magnetic core for vibration analysis
Authors: Marks Janis , Vitolina Sandra 
Published: January 2018

Abstract
Magnetostriction is a phenomenon occurring in transformer core in normal operation mode. Yet in time, it can cause the delamination of magnetic core resulting in higher level of vibrations that are measured on the surface of transformer tank during diagnostic tests. The aim of this paper is to create a model for evaluating elastic deformations in magnetic core that can be used for power transformers with intensive vibrations in order to eliminate magnetostriction as a their cause. Description of the developed model in Matlab and COMSOL software is provided including restrictions concerning geometry and properties of materials, and the results of performed research on magnetic core anisotropy are provided. As a case study modelling of magnetostriction for 5-legged 200 MVA power transformer with the rated voltage of 13.8/137kV is conducted, based on which comparative analysis of vibration levels and elastic deformations is performed.
Field analysis & eddy current losses calculation in five-phase tubular actuator
Authors: Waindok Andrzej , Tomczuk Bronislaw 
Published: January 2018

Abstract
Field analysis including eddy currents in the magnetic core of five-phase permanent magnet tubular linear actuator (TLA) has been carried out. The eddy currents induced in the magnetic core cause the losses which have been calculated. The results from 2D finite element (FE) analysis have been compared with those from 3D calculations. The losses in the mover of the five-phase actuator are much lower than the losses in its stator. That is why the former ones can be neglected in the computer aided designing. The calculation results have been verified experimentally

Published: January 2018

Abstract
Aim. The aim of the study was to determine the relationship between the mode of delivery and the course of lactation in primiparas in early postpartum period. Material and methods. The research was conducted amongst 200 primiparas including 100 after vaginal delivery and 100 after cesarean section. The study was conducted with the method of diagnostic survey with the author’s original questionnaire as a research tool. Results. The women after vaginal delivery initiate breastfeeding earlier and more often find it successful (p < 0.001). Almost all the primiparas after cesarean delivery formula-fed their newborns (p < 0.001) and they started supplementary formula feeding earlier in comparison to women who had vaginal delivery (p < 0.001). Problem-free breastfeeding was declared by 15% of the respondents after vaginal delivery and 4% of those who had a cesarean section. Conclusions. The mode of delivery influences the lactation process. The primiparas after cesarean delivery had problems with breastfeeding more often than those after vaginal birth.
Independence and domination on shogiboard graphs
Authors: Chatham Doug 
Published: January 2018

AbstractGiven a (symmetrically-moving) piece from a chesslike game, such as shogi, and an n×n board, we can form a graph with a vertex for each square and an edge between two vertices if the piece can move from one vertex to the other. We consider two pieces from shogi: the dragon king, which moves like a rook and king from chess, and the dragon horse, which moves like a bishop and rook from chess. We show that the independence number for the dragon kings graph equals the independence number for the queens graph. We show that the (independent) domination number of the dragon kings graph is n − 2 for 4 ≤ n ≤ 6 and n − 3 for n ≥ 7. For the dragon horses graph, we show that the independence number is 2n − 3 for n ≥ 5, the domination number is at most n−1 for n ≥ 4, and the independent domination number is at most n for n ≥ 5.
An Attempt to Design a Naturally Ventilated Tower in Subtropical Climate of the Developing Country; Pakistan
Authors: Sohail Maha 
Published: January 2018

Abstract
A large proportion of the world’s population resides in developing countries where there is a lack of rigorous studies in designing energy efficient buildings. This study is a step in designing a naturally ventilated high rise residential building in a tropical climatic context of the developing country, Pakistan. Karachi, the largest city of Pakistan, lies in the subtropical hot desert region with constant high temperature of average 32 °C throughout the summer and no particular winter season. The Design Builder software package is used to design a 25 storey high rise residential building relying primarily on natural ventilation. A final conceptual design is proposed after optimization of massing, geometry, orientation, and improved building envelope design including extensive shading devices in the form of trees. It has been observed that a reduction of 8 °C in indoor ambient temperature is possible to achieve with passive measures and use of night time ventilation. A fully naturally ventilated building can reduce the energy consumption for cooling and heating by 96 % compared to a building using air conditioning systems.

Depression is associated with CRP SNPs in patients with family history
Authors: Yibulaiyin Hasiyeti- , Sun Haixia , Yang Yue 
Published: January 2018

AbstractObjectiveThe pathogenesis of depression is not fully understood, but studies have suggested that higher circulating levels of C reactive protein (CRP) might relate to depression occurrence. However, due to the highly variability of individual patients’ conditions, the results to date are inconsistent. Considering Single nucleotide polymorphisms (SNPs) of CRP gene have also been suggested to predict plasma CRP levels. In the present study, we hypothesize that inherited CRP allelic variations may co-vary with depressive symptomatology.MethodsWe recruited patients with a diagnosis of depression, with or without family depression history. We then detected serum CRP levels, as well as genome CRP SNPs from participants of this project.ResultsWe found a significantly higher circulating CRP levels in patients with a positive family history. Furthermore, we also identified certain inherited CRP SNPs (A allele in rs1417938 and C allele in rs1205) which could up-regulate serum CRP levels and thus be associated with depression occurrence.ConclusionOur findings raise new evidence for the relationship between circulating CRP level and depression occurrence.
Investigating the Relationship of the Functional Gait Assessment to Spatiotemporal Parameters of Gait and Quality of Life in Individuals With Stroke
Authors: Price Richard , Choy Nancy Low 
Published: January 2018

Background and Purpose:
Walking in the community is an important aspect of independence and quality of life (QOL) that poses challenges for individuals with stroke. This study investigated whether performance on the Functional Gait Assessment (FGA) differentiated spatiotemporal gait parameters, QOL, and fall history of community-ambulating individuals with stroke. We hypothesized that those scoring higher on the FGA would present with better gait speed and cadence, stride width and length, and improved load time on the paretic limb, report a higher QOL, and be less likely to have a fall history than those who scored lower on the FGA.

Methods:
Participants were screened for cognitive impairment and the ability to walk independently. Participant demographics and stroke characteristics were recorded. The Falls Risk for Older People in the Community (FROP-Com) screening tool determined whether the participant had incurred 1 or more falls within the preceding 12 months. The FGA provided a composite measure of gait with varied walking tasks challenging different aspects of walking. The total score was recorded. The GAITRite instrumented-walkway was used to acquire high-resolution footfall data during performance of the first 9 FGA walking tasks. The Assessment of Quality of Life-6D (AQoL-6D) was used to measure health-related QOL across the domains of independent living, mental health, coping, relationships, pain, and senses. Pearson and Spearman correlations were used to check for correlations between FGA score and the demographic characteristics, AQoL-6D scores, and 12-month fall history. Pearson correlations were used to check for correlations between FGA score and multiple spatiotemporal gait parameters for each FGA item.

Results and Discussion:
A sample of 29 volunteers who were community-ambulating individuals with stroke was recruited. Participants had a mean age of 62.31 (10.89) years, mean time since stroke of 3.78 (4.10) years, and included both males and females (52% male). Individuals presented with both left- and right-sided strokes. FGA score correlated positively with velocity, cadence, and step length, and negatively with stride width, double-support percent, and single-support variability (P = .001 to P = .031). FGA score correlated positively with the AQoL-6D dimension of independent living. FGA score correlated significantly with the FROP-Com screening tool predicted fall risk, but not with fall history.

Conclusions:
The FGA is a clinical measure of functional gait performance that reflected spatiotemporal gait parameters and ability of individuals with chronic stroke to live independently. The FGA could be used to target interventions to improve functional gait performance of individuals with chronic stroke.
Muscle Nicotinic Acetylcholine Receptors May Mediate Trans-Synaptic Signaling at the Mouse Neuromuscular Junction
Authors: Wang Xueyong , McIntosh J. Michael , Rich Mark M. 
Published: January 2018

Block of neurotransmitter receptors at the neuromuscular junction (NMJ) has been shown to trigger upregulation of the number of synaptic vesicles released (quantal content, QC), a response termed homeostatic synaptic plasticity. The mechanism underlying this plasticity is not known. Here, we used selective toxins to demonstrate that block of α1-containing nicotinic acetylcholine receptors (nAChRs) at the NMJ of male and female mice triggers the upregulation of QC. Reduction of current flow through nAChRs, induced by drugs with antagonist activity, demonstrated that reduction in synaptic currentper sedoes not trigger upregulation of QC. These data led to the remarkable conclusion that disruption of synaptic transmission is not sensed to trigger upregulation of QC. During studies of the effect of partial block of nAChRs on QC, we observed a small but reproducible increase in the decay kinetics of miniature synaptic currents. The change in kinetics was correlated with the increase in QC and raises the possibility that a change in postsynaptic nAChR conformation may be associated with the presynaptic increase in QC. We propose that, in addition to functioning in synaptic transmission, ionotropic muscle nicotonic nAChRs may serve as signaling molecules that participate in synaptic plasticity. Because nAChRs have been implicated in a number of disease states, the finding that nAChRs may be involved in triggering synaptic plasticity could have wide-reaching implications.SIGNIFICANCE STATEMENTThe signals that initiate synaptic plasticity of the nervous system are still incompletely understood. Using the mouse neuromuscular junction as a model synapse, we studied how block of neurotransmitter receptors is sensed to trigger synaptic plasticity. Our studies led to the surprising conclusion that neither changes in synaptic current nor spiking of the presynaptic or postsynaptic cell are sensed to initiate synaptic plasticity. Instead, postsynaptic nicotinic acetylcholine receptors (nAChRs), in addition to functioning in synaptic transmission, may serve as signaling molecules that trigger synaptic plasticity. Because nAChRs have been implicated in a number of disease states, the finding that they may mediate synaptic plasticity has broad implications.

Published: January 2018

CONTEXT:
The association between acid-suppressive drug exposure during pregnancy and childhood asthma has not been well established.

OBJECTIVE:
To conduct a systematic review and meta-analysis on this association to provide further justification for the current studies.

DATA SOURCES:
We searched PubMed, Medline, Embase, the Cochrane Database of Systematic Reviews, EBSCO Information Services, Web of Science, and Google Scholar from inception until June 2017.

STUDY SELECTION:
Observational studies in which researchers assessed acid-suppressive drug use during pregnancy and the risk of childhood asthma were included.

DATA EXTRACTION:
Of 556 screened articles, 8 population-based studies were included in the final analyses.

RESULTS:
When all the studies were pooled, acid-suppressive drug use in pregnancy was associated with an increased risk of asthma in childhood (relative risk [RR] = 1.45; 95% confidence interval [CI] 1.35–1.56; I2 = 0%; P &lt; .00001). The overall risk of asthma in childhood increased among proton pump inhibitor users (RR = 1.34; 95% CI 1.18–1.52; I2 = 46%; P &lt; .00001) and histamine-2 receptor antagonist users (RR = 1.57; 95% CI 1.46–1.69; I2 = 0%; P &lt; .00001).

LIMITATIONS:
None of the researchers in the studies in this meta-analysis adjusted for the full panel of known confounders in these associations.

CONCLUSIONS:
The evidence suggests that prenatal, maternal, acid-suppressive drug use is associated with an increased risk of childhood asthma. This information may help clinicians and parents to use caution when deciding whether to take acid-suppressing drugs during pregnancy because of the risk of asthma in offspring.
