Continuous Indoor Positioning Fusing WiFi, Smartphone Sensors and Landmarks

To exploit the complementary strengths of WiFi positioning, pedestrian dead reckoning (PDR), and landmarks, we propose a novel fusion approach based on an extended Kalman filter (EKF). For WiFi positioning, unlike previous fusion approaches setting measurement noise parameters empirically, we deploy a kernel density estimation-based model to adaptively measure the related measurement noise statistics. Furthermore, a trusted area of WiFi positioning defined by fusion results of previous step and WiFi signal outlier detection are exploited to reduce computational cost and improve WiFi positioning accuracy. For PDR, we integrate a gyroscope, an accelerometer, and a magnetometer to determine the user heading based on another EKF model. To reduce accumulation error of PDR and enable continuous indoor positioning, not only the positioning results but also the heading estimations are recalibrated by indoor landmarks. Experimental results in a realistic indoor environment show that the proposed fusion approach achieves substantial positioning accuracy improvement than individual positioning approaches including PDR and WiFi positioning.
Museums and Social Inclusion, Exploring the Geography of School Visits to Museums

Recent government funding for museums in the UK has identified museums as vehicles for addressing socio-economic issues such as urban regeneration and social inclusion. This paper examines the role that geography can play in assessing whether museums are engaging with these issues. Between 20032006 three major evaluations were funded by government agencies to analyse the contribution that museum education events make to tackling social agendas. This paper builds on conclusions made in these previous studies by examining in closer detail the locations of the schools and museums and re-examining the geography of visits by considering alternative interpretations of it. The paper demonstrates that by considering the geography of school visits a greater understanding of the socio-economic contexts of museum audiences can be reached. The geography of school visits raises many questions about how museums address social inclusion and the specific contexts and impacts of each school visit, these issues are subjects for further qualitative analysis.
A Note on the Call-Put Parity and a Call-Put Duality

Along with the well-known “call-put parity” relation, that makes it possible to express the rational price of a put option in terms of the rational price of a call option, we introduce a “call-put duality” relation. This new concept offers a simple explanation of the relationship between the rational price of a put option and a call option, not only for options of the European type, but also for options of the American type.
Paired Serum and Urine Concentrations of Biomarkers of Diethyl Phthalate, Methyl Paraben, and Triclosan in Rats

Background Exposure to environmental chemicals, including phthalates and phenols such as parabens and triclosan, is ubiquitous within the U.S. general population. Objective This proof-of-concept rodent study examined the relationship between oral doses of three widely used personal care product ingredients [diethyl phthalate (DEP), methyl paraben (MPB), and triclosan] and urine and serum concentrations of their respective biomarkers. Methods Using female Sprague-Dawley rats, we carried out two rounds of experiments with oral gavage doses selected in accordance with no observed adverse effect levels (NOAELs) derived from previous studies: 1,735 (DEP), 1,050 (MPB), 50 (triclosan) mg/kg/day. Administered doses ranged from 0.005 to 173 mg/kg/day, 10–100,000 times below the NOAEL for each chemical. Controls for the MPB and triclosan experiments were animals treated with olive oil (vehicle) only; controls for the DEP serum experiments were animals treated with the lowest doses of MPB and triclosan. Doses were administered for 5 days with five rats in each treatment group. Urine and blood serum, collected on the last day of exposure, were analyzed for biomarkers. Relationships between oral dose and biomarker concentrations were assessed using linear regression. Results Biomarkers were detected in all control urine samples at parts-per-billion levels, suggesting a low endemic environmental exposure to the three chemicals that could not be controlled even with all of the precautionary measures undertaken. Among the exposed animals, urinary concentrations of all three biomarkers were orders of magnitude higher than those in serum. A consistently positive linear relationship between oral dose and urinary concentration was observed (R2 > 0.80); this relationship was inconsistent in serum. Conclusions Our study highlights the importance of carefully considering the oral dose used in animal experiments and provides useful information in selecting doses for future studies.

Cancer Therapy : Preclinical Silencing Survivin Splice Variant 2 B Leads to Antitumor Activity in Taxane-Resistant Ovarian Cancer

Purpose: To study the role of survivin and its splice variants in taxane-resistant ovarian cancer. Experimental Design: We assessed the mRNA levels of survivin splice variants in ovarian cancer cell lines and ovarian tumor samples. siRNAs targeting survivin were designed to silence all survivin splice variants (T-siRNA) or survivin 2B (2B-siRNA) in vitro and orthotopic murine models of ovarian cancer. The mechanism of cell death was studied in taxane-resistant ovarian cancer cells and in tumor sections obtained from different mouse tumors. Results: Taxane-resistant ovarian cancer cells express higher survivin mRNA levels than their taxanesensitive counterparts. Survivin 2B expression was significantly higher in taxane-resistant compared with -sensitive cells. Silencing survivin 2B induced growth inhibitory effects similar to silencing total survivin in vitro. In addition, survivin 2B-siRNA incorporated into DOPC (1,2-dioleoyl-sn-glycero-3-phosphocholine) nanoliposomes resulted in significant reduction in tumor growth (P < 0.05) in orthotopic murine models of ovarian cancer, and these effects were similar to T-siRNA-DOPC. The antitumor effects were further enhanced in combination with docetaxel chemotherapy (P < 0.01). Finally, we found a significant association between survivin 2B expression and progression-free survival in 117 epithelial ovarian cancers obtained at primary debulking surgery. Conclusions: These data identify survivin 2B as an important target in ovarian cancer and provide a translational path forward for developing new therapies against this target.

Recognition of emotional pictures: Behavioural and electrophysiological measures

The effects of emotional content of images on recognition memory were studied, bringing together electrophysiological (Event-Related brain Potentials, ERPs) and behavioural (accuracy and speed of recognition, and remember/know judgements) indices. In the study phase, participants assessed 120 images on the scales of valence and arousal. In the test phase, ERPs were recorded while participants viewed again the images, put together with 120 new, and were asked to make old/new decisions and remember/know judgements on them. A clear arousal bias was obtained for remember/know judgements, which revealed that correctly recognised arousing images (negative and positive) received more remember judgements than nonarousing images (neutral and relaxing). Moreover, a Late Positive Component (LPC) activation revealed an old/new effect enhanced by arousing images. The LPC activation was located in parietal areas (precuneus), which appears to be mostly related to successful retrieval based on recollection. The results obtained through different indices supported the emotional bias found in previous studies for arousing material, but do not clarify the effect of the emotional valence on recognition.
Hospitalizations for alcohol and drug overdoses in young adults ages 18-24 in the United States, 1999-2008: results from the Nationwide Inpatient Sample.

OBJECTIVE Recent reports indicate an increase in rates of hospitalizations for drug overdoses in the United States. The role of alcohol in hospitalizations for drug overdoses remains unclear. Excessive consumption of alcohol and drugs is prevalent in young adults ages 18-24. The present study explores rates and costs of inpatient hospital stays for alcohol overdoses, drug overdoses, and their co-occurrence in young adults ages 18-24 and changes in these rates between 1999 and 2008. METHOD Data from the Nationwide Inpatient Sample were used to estimate numbers, rates, and costs of inpatient hospital stays stemming from alcohol overdoses (and their subcategories, alcohol poisonings and excessive consumption of alcohol), drug overdoses (and their subcategories, drug poisonings and nondependent abuse of drugs), and their co-occurrence in 18- to 24-year-olds. RESULTS Hospitalization rates for alcohol overdoses alone increased 25% from 1999 to 2008, reaching 29,412 cases in 2008 at a cost of $266 million. Hospitalization rates for drug overdoses alone increased 55%, totaling 113,907 cases in 2008 at a cost of $737 million. Hospitalization rates for combined alcohol and drug overdoses increased 76%, with 29,202 cases in 2008 at a cost of $198 million. CONCLUSIONS Rates of hospitalizations for alcohol overdoses, drug overdoses, and their combination all increased from 1999 to 2008 among 18- to 24-year-olds. The cost of such hospitalizations now exceeds $1.2 billion annually. The steepest increase occurred among cases of combined alcohol and drug overdoses. Stronger efforts are needed to educate medical practitioners and the public about the risk of overdoses, particularly when alcohol is combined with other drugs.
Stem Cell Therapy: A New Therapeutic Option for Cardiovascular Diseases

Cardiovascular diseases are known as one of major causes of morbidity and mortality worldwide. Despite the many advancement in therapies are associated with cardiovascular diseases, it seems that finding of new therapeutic option is necessary. Cell therapy is one of attractive therapeutic platforms for treatment of a variety of diseases such as cardiovascular diseases. Among of various types of cell therapy, stem cell therapy has been emerged as an effective therapeutic approach in this area. Stem cells divided into multipotent stem cells and pluripotent stem cells. A large number studies indicated that utilization of each of them are associated with a variety of advantages and disadvantages. Multiple lines evidence indicated that stem cell therapy could be used as suitable therapeutic approach for treatment of cardiovascular diseases. Many clinical trials have been performed for assessing efficiency of stem cell therapies in human. However, stem cell therapy are associated with some challenges, but, it seems resolving of them could contribute to using of them as effective therapeutic approach for patients who suffering from cardiovascular diseases. In the current review, we summarized current therapeutic strategies based on stem cells for cardiovascular diseases. J. Cell. Biochem. 119: 95–104, 2018. © 2017 Wiley Periodicals, Inc.
Secondary prevention of coronary artery disease in contemporary clinical practice.

BACKGROUND The highest priority in preventive cardiology was given to patients with established coronary artery disease (CAD). The aim of the study was to assess the implementation of guidelines for secondary prevention in everyday clinical practice by evaluating control of the main risk factors and the cardioprotective medication prescription rates for patients, following their hospitalization for CAD. METHODS Five hospitals with cardiology departments serving the city and its surround-ing districts in southern part of Poland participated in the study. Consecutive patients aged ≤ 80 years, hospitalized from January 1 2010 to April 31 2012 due to an acute coronary syndrome or for a myocardial revascularization procedure were recruited and interviewed 6-18 months after hospitalization. RESULTS The medical records of 595 patients (mean age: 62.8 ± 9.0 years, 397 men and 198 women) were reviewed and included in the analyses. Proportions of medical records with available information on risk factors were high with the exception of total cholesterol levels as well as weight and height measurements, which were available in less than 80% of the hospital records. The prescription rate at discharge for antiplatelets was 99%, beta-blockers (BB)--85%, angiotensin converting enzyme inhibitors (ACEI) or sartans--85%, and lipid-lowering drugs--94%. Patients scheduled for coronary artery bypass grafting were significantly less often prescribed BB, ACEI or sartans, and lipid-lowering drugs. The proportion of patients with high blood pressure (≥ 140/90 mm Hg) 6-18 months after hospitalization was 47%, with high LDL cholesterol level (≥ 1.8 mmol/L) 73%, and with a high HbA1c level (≥ 7.0%) 14%, whereas 20% of participants were smokers and 80% were overweight. The proportion of patients taking an antiplatelet agent 6-18 months after hospitalization was 90%, BB--82%, ACEI--or sartan 78%, and lipid-lowering drug--82%. Overall, 33.9% of the study participants declared that they had been advised to participate in a rehabilitation/secondary prevention program following their hospitalization and 30.5% participated in a rehabilitation/secondary prevention program. However, only 28.2% took part in at least half of the planned sessions. Using a multivariate analysis we showed that, in general, risk factors control and the prescription rates of cardioprotective medications were related to the patients' age, education, and participation in a rehabilitation/secondary prevention program following their hospitalization due to CAD. CONCLUSIONS Our data provide evidence that there is a considerable potential for further reduction of cardiovascular risk in CAD patients. Our results suggest that increasing patient participation rates in rehabilitation/secondary prevention programs may improve the implementation of the secondary prevention.
Mutations in the Middle of the Transmembrane Domain Reverse the Polarity of Transport of the Influenza Virus Hemagglutinin in MDCK Epithelial Cells

The composition of the plasma membrane domains of epithelial cells is maintained by biosynthetic pathways that can sort both proteins and lipids into transport vesicles destined for either the apical or basolateral surface. In MDCK cells, the influenza virus hemagglutinin is sorted in the trans-Golgi network into detergent-insoluble, glycosphingolipid-enriched membrane domains that are proposed to be necessary for sorting hemagglutinin to the apical cell surface. Site- directed mutagenesis of the hemagglutinin transmembrane domain was used to test this proposal. The region of the transmembrane domain required for apical transport included the residues most conserved among hemagglutinin subtypes. Several mutants were found to enter detergent-insoluble membranes but were not properly sorted. Replacement of transmembrane residues 520 and 521 with alanines converted the 2A520 mutant hemagglutinin into a basolateral protein. Depleting cell cholesterol reduced the ability of wild-type hemagglutinin to partition into detergent-insoluble membranes but had no effect on apical or basolateral sorting. In contrast, cholesterol depletion allowed random transport of the 2A520 mutant. The mutant appeared to lack sorting information but was prevented from reaching the apical surface when detergent-insoluble membranes were present. Apical sorting of hemagglutinin may require binding of either protein or lipids at the middle of the transmembrane domain and this normally occurs in detergent-insoluble membrane domains. Entry into these domains appears necessary, but not sufficient, for apical sorting.
Seroprevalence of Transmisive Diseases in Healthy Blood Donors: a Five-year Experience in University Clinical Center Tuzla

Background: The safety of blood products is the most important task of transfusion medicine. Transfusion-transmitted diseases represent a serious public health problem throughout the world, although their percentage of transmission is minimal. Each blood donation is individually tested with serological and molecular tests for the presence of hepatitis B and C viruses, human immunodeficiency virus (HIV), and Treponema Pallidum, regardless of the number of blood donations. Objective: To determine the seroprevalence of blood-borne diseases in healthy blood donors at the University Clinical Center Tuzla, to analyze the possible causes of transmission of these diseases, and to compare with the results of research in countries in the region and beyond. Methods: The research was conducted retrospectively in the period January 1, 2018. until 31.12. 2022. years. Samples of blood donors were tested for hepatitis B surface antigen (HBsAg), antibodies to human immunodeficiency virus (HIV1/2), antibodies to hepatitis C and syphilis, using the fourth generation ELISA method. Results: The highest frequency of transmisive disease markers was reactivity to HBsAg with a total of 63.7% of cases and a prevalence of 0.13%, and the lowest for HIV with a total of 1.4% and a prevalence of 0.003%. Conclusion: Bosnia and Herzegovina has a very low seroprevalence but there is still a risk of disease transmission in the population.
Design of an Implantable Slot Dipole Conformal Flexible Antenna for Biomedical Applications

We present a flexible folded slot dipole implantable antenna operating in the Industrial, Scientific, and Medical (ISM) band (2.4-2.4835 GHz) for biomedical applications. To make the designed antenna suitable for implantation, it is embedded in biocompatible Polydimethylsiloxane (PDMS). The antenna was tested by immersing it in a phantom liquid, imitating the electrical properties of the human muscle tissue. A study of the sensitivity of the antenna performance as a function of the dielectric parameters of the environment in which it is immersed was performed. Simulations and measurements in planar and bent state demonstrate that the antenna covers the complete ISM band. In addition, Specific Absorption Rate (SAR) measurements indicate that the antenna meets the required safety regulations.
Validating the Psycho-social Challenges Associated with the Current RDP Houses: The Case of Golf Course 2011-2013 Study, Eastern Cape

Abstract This paper sought to validate the psycho-social challenges experienced by residents of Golf Course RDP housing project in Alice township. This study triangulated both qualitative and quantitative approaches with the qualitative approach being the dominant one, while the quantitative was less dominant. The study utilized an interview guide with unstructured questions as a data collection tool for one-on-one in-depth interviews, while a likert scale designed questionnaire was utilized for the questionnaire interviews. Findings from this study indicated the poor state of houses epitomized by cracking floors, walls emitting dust, weaker doors and windows, falling roofs; unreliability of water and other important social amenities. These researchers recommended to the government to consider renovating and escalating the provision of water to the houses to give them a dignified phase for human living. It is also essential for the social work role to be expanded in order to offer therapeutic interventions to the psychologically drained RDP dwellers.
Prehospital Airway Management in Emergency and Trauma Patients: A Cross-sectional Study of Ambulance Service Providers and Staff in a Low- and Middle-income Country

Abstract Background Prehospital airway management (AM) is the first priority in the care of emergency and trauma victims as it has shown to improve survival in these patients. Objective The aim of this study was to assess training and knowledge of ambulance staff and availability of AM equipment in ambulances of Karachi, Pakistan. Methods This cross-sectional study was conducted from June through September 2014. Interviews were conducted with management of six ambulance service providers and 165 ambulance staff. Data from the management included availability of AM equipment in the ambulances, number and designation of staff sent for emergency calls, and AM training of staff. Ambulance staff were assessed for their awareness, knowledge, and training pertaining to AM. Results All the ambulance services (A through F) had basic equipment for AM but lacked qualified and trained staff. All services had solo drivers (98.3%) for emergency calls; however, Ambulance Service A also had doctors and paramedics. Only 35.7% (59/165) of ambulance staff had awareness regarding AM, out of which 77.9% (46/59) belonged to Ambulance Service A. Of these 59 staff, 81.4% received some form of AM training. Staff with AM awareness, when assessed for knowledge pertaining to AM steps and AM equipment, had a mean score of 4.7/5 and 8.4/12, respectively. Conclusion Even though ambulances are equipped with basic equipment, due to lack of trained staff, these ambulances only serve the mere purpose of transportation. There is a need to train ambulance staff and increase ambulance to staff ratio to improve prehospital AM and patient survival. IsmailS, ZiaN, SamadK, NaeemR, AhmadH, RazaA, BaqirM, KhanUR.

Ramsar international wetlands of Alagol, Almagol and Ajigol in eastern parts of the Caspian Sea: a floristic and habitat survey

Ramsar international wetlands of Alagol, Almagol and Ajigol with a surface of 3027 ha are located in the vast Turkmen-Sahra plains (Golestan prov.) in east of Caspian Sea and in the vicinity of the Iran-Turkmenistan political border. Flora, vegetation and habitat diversity of the wetlands were surveyed during growing seasons of 2014 and 2015. A total of 159 plant taxa belonging to 123 genera and 42 families were determined in the studied wetlands. Asteraceae, Amaranthaceae (including Chenopodiaceae) and Poaceae were the most species rich families and Suaeda, Salsola, Atriplex, Plantago and Tamarix were the most species rich genera. A floristic analysis indicated that therophytes and pluriregional elements predominated life form and chorological spectra, respectively. Studied sites were physiognomically classified into aquatic, emergent, and dry upland habitats which represent 6, 68 and 26 percent of all plant taxa, respectively. Halophytic species constitute a large part of flora, among them Puccinellia poecilantha recently recorded in the area is considered as a rare plant. The results may be applied in designing conservation areas and developing conservation strategies for this unique wetland ecosystem.
