Authors: Vizeu Alfredo , Leite Flora
Published: June 2018

O telejornal é o grande meio de informação da maioria dos brasileiros e brasileiras. O noticiário televisivo contribui de forma relevante para apresentar o mundo que cerca homens e mulheres no seu dia a dia, tanto no que diz respeito aos aspectos sociais, culturais, políticos e econômicos, quanto, em particular, acerca dos fatos que ocorrem no cotidiano, como manifestações, greves, etc. É considerando isso que este trabalho busca revisitar a pesquisa que realizamos há 20 anos, sobre o processo de decisão dos jornalistas acerca do que é noticiável. A intenção é apresentar alguns aspectos presentes hoje no jornalismo e que inexistiam em 1997. Por fim, procuramos destacar como estas mudanças podem interferir no processo democrático.
AS NOTÍCIAS COMO PRÁTICA COLETIVA E CONVENCIONAL: a abordagem beckeriana aplicada aos estudos do jornalismo
Authors: Pereira Fábio Henrique
Published: June 2018

O artigo propõe a aplicação dos conceitos de mundo social e de convenções, originários da sociologia das formas de representação da sociedade de Howard Becker, aos estudos de jornalismo. Postula-se a ideia de que a noticiabilidade consistiria em um sistema de convenções que fornece as bases para um processo mais amplo de negociação entre jornalistas, fontes, públicos, e os demais colaboradores do jornalismo, prática considerada aqui como um ato social maior. Com isso, busca mapear as possíveis contribuições de uma abordagem interacionista para a compreensão da atividade jornalística como uma prática dinâmica e coletiva.

A ESCRITA: uma prática movida pela busca da melhor adequação da execução à intenção
Authors: Pinto Maria da Graça Lisboa Castro
Published: June 2018

Objetiva este texto desmontar o processo da escrita-composição evidenciando a importância de que se reveste o desdobramento do escritor/autor em diferentes papéis, que vão de leitor a editor, passando por investigador, descobridor, revisor e crítico. Observa-se, então, a diferença entre o exercício de todas essas funções pelo próprio autor e a sua assunção por diferentes agentes numa ótica da construção da obra pela divisão do trabalho, conforme propõe o narrador de S. Bernardo, de Graciliano Ramos, no início do romance. Para sustentar a argumentação necessária foi crucial o recurso a depoimentos de profissionais da escrita, porquanto atestam na primeira pessoa a dificuldade inerente a essa tarefa. A lição a retirar deste texto vai na direção de incentivar a prática desse processo verbal, com vista à melhor adequação da “execução” à “intenção” (Sommers, 1980), dado que a escrita só pode tornar-se menos distante e mais familiar, se for praticada com assiduidade e com informação acerca da sua dinâmica.

Published: June 2018

Logistics Engineering has transcended over the decades into an approach for competitive benefits in organisational performance and logistics efficiency. Most industries are recognising that significant savings are available to companies that are able to ordinate and improve within their logistics operations. Companies today face great challenges because the successful supply of many products and services needs to the effective integration of logistics activities across a prolongation supply chain and an increasing geographical separation. Moreover, logistics integration approach involves both internal integration for an ordinated, unified process as well as relationships to react flexibly, changeability, and responsibility to customer's demands. In this study, by using of Fuzzy Vikor (F-Vikor), the best combination of RIR was selected and RIR Locating was done. The main aim of this paper is survey and design of the integrated operational logistics network (IOLN) and also, a proposed IOLN to integration of the Iran Khodro Co Supply Network.

Published: June 2018

. Sealants and adhesives are used in the repair and preservation of damaged solid organs. This study examines the matrix metalloproteinases (MMP) activity in the healing of liver injuries treated with two biological adhesives (Tachosil® and GelitaSpon®) as well as that of a new elastic cyanoacrylate (Adhflex®). Methods. We induced in 90 male rats hepatic lesions using a Stiefel biopsy punch in the liver. Wound healing was assessed 2, 6, and 18 days after injury by quantifying MMP1, 2, 8, 9, and 13 tissue levels. The histopathological repair was evaluated by hematoxylin-eosin, Masson’s trichrome, and Periodic Acid Schiff (PAS) staining and CD31, CD68 immunohistochemical marker. The three sealants used contributed to the complete healing of hepatic lesions. Both histopathology and MMP findings point to the fact that degradation with Adhflex® is slower and causes a strong inflammatory reaction at the onset of healing. Results. All the MMPs measured showed higher values early in the healing process in animals treated with Adhflex® and Tachosil, expression for MMP2 and MMP9 being significantly higher in the Adhflex-treated group. Animals treated with Tachosil had significant greater values of MMP8 and MPP13 than the Adhflex group. Animals treated with Adhflex® showed a sustained overexpression in all MMPs even at the latest wound healing stages. Conclusion. Notably, the overexpression of the MMPs did not negatively influence the histological healing process of liver injuries. Since all hepatic trauma injuries should be treated as emergencies, any easy-to-use and rapid sealant, like Adhflex®, could be considered an adequate treatment option.
Olive Oil and Diabetes: From Molecules to Lifestyle Disease Prevention
Authors: Alkhatib Ahmad , Tsang Catherine , Tuomilehto Jaakko
Published: June 2018

Lifestyle is the primary prevention of diabetes, especially type-2 diabetes (T2D). Nutritional intake of olive oil (OO), the key Mediterranean diet component has been associated with the prevention and management of many chronic diseases including T2D. Several OO bioactive compounds such as monounsaturated fatty acids, and key polyphenols including hydroxytyrosol and oleuropein, have been associated with preventing inflammation and cytokine-induced oxidative damage, glucose lowering, reducing carbohydrate absorption and increasing insulin sensitivity and related gene expression. However, research into the interaction of OO nutraceuticals with lifestyle components, especially physical activity is lacking. Promising postprandial effects have been reported when OO or other similar monounsaturated fatty acids was the main dietary fat compared with other diets. Animal studies have shown a potential anabolic effect of oleuropein. Such effects could be further potentiated via exercise, especially strength training, which is an essential exercise prescription for individuals with T2D. There is also an evidence from in vitro, animal and limited human studies for a dual preventative role of OO polyphenols in diabetes and cancer, especially that they share similar risk factors. Putative anti-oxidative and anti-inflammatory mechanisms and associated gene expressions resulting from OO phenolics, have produced paradoxical results making suggested inferences from dual prevention T2D and cancer outcomes difficult. Well-designed human interventions and clinical trials are needed to decipher such a potential dual anti-cancer and anti-diabetic effects of OO nutraceuticals. Exercise combined with OO consumption, individually or as part of a healthy diet is likely to induce reciprocal action for T2D prevention outcomes.
Cosmological Constant Decaying with CMB Temperature
Authors: Sonoda Tomohide
Published: June 2018

Recent observations of the dark energy density demonstrates the fine-tuning problem and challenges in theoretical modelling. In this study, we apply the self-similar symmetry (SSS) model, describing the hierarchical structure of the universe based on the Dirac large numbers hypothesis, to Einstein's cosmological term. We introduce a new similarity dimension, DB, in the SSS model. Using the DB SSS model, the cosmological constant Λ is simply expressed as a function of the cosmic microwave background (CMB) temperature. The result gives a natural interpretation of the cosmological scenario and helps understanding the extreme smallness of the present value of Λ without fine-tuning.
Less Is More: Basing on Dynamic Mixed Game Analysis on the Real Estate Regulation Policy Between Central and Local Government in China
Authors: Ma Weimin , Zhang Ranran , Ke Hua
Published: June 2018

Over the past decade, the high and rising housing prices in China, which have brought serious problems in people's livelihood, have attracted worldwide attention. The central government has constantly put forward some tight real estate regulation policies, while house prices still have not cooled down and continued to rise. In order to study this phenomenon, we try to analyze using game models: First, considering the simple model without a penalty mechanism, we find that the central and local government both has dominant strategies, and the Nash equilibrium formed is not Pareto optimal of the prisoner's dilemma. Second, a penalty mechanism considering local governments' policy boycott is introduced into mixed game model, trying to analyze the impact of the mechanism on both sides of the game. Interestingly, because of the asymmetry of information, the local would actively implement with the high level of resistance. In the end, the central government's deterrent force is considered into a dynamic mixed game, where exists a bayesian equilibrium. The results show that the central government can achieve the goal of policy by means of improving the efficiency of supervision and reducing the frequency of supervision. Managerial and theoretical implications are discussed.
A Review of the Complex Roles of Glial Cells in Alzheimer’s Disease and Potential Glial-Oriented Therapeutic Targets
Authors: Nirzhor Saif Shahriar Rahman , Khan Rubayat Islam , Neelotpol Sharmind
Published: June 2018

The pathogenesis of Alzheimer’s disease (AD) is very complicated and not well-understood. As more and more studies are performed with regards to this disease, new insights are coming to light. Much of the research in AD so far has been very neuron-oriented however, recent studies suggest that certain glial cells i.e. microglia, astrocytes, oligodendrocytes, and NG2 glia are linked to the pathogenesis of AD and may offer several potential therapeutic targets in the long-standing battle against AD. Glial cells are responsible for maintaining homeostasis (i.e. concentration of ions and neurotransmitters) within the neuronal environment of the central nervous system (CNS) and are crucial to the integrity of neurons. This review explores the (1) role of glial cells in AD pathogenesis, (2) complex functionalities of the components involved and (3) potential therapeutic targets that it could eventuate leading to a better quality of life for AD patients.
Land Surface Albedo Derived on a Ten Daily Basis from Meteosat Second Generation Observations: the NRT and Climate Data Record Collections from the EUMETSAT LSA SAF

Published: June 2018

Land surface albedo determines the splitting of downwelling solar radiation into components which are either reflected back to the atmosphere or absorbed by the surface. Land surface albedo is an important variable for the climate community and therefore was defined by the Global Climate Observing System (GCOS) as an Essential Climate Variable (ECV). Within the scope of the Satellite Application Facility for Land Surface Analysis (LSA SAF) of EUMETSAT, a near-real time (NRT) daily albedo product was developed in the last decade from observations provided by the SEVIRI instrument on board the geostationary satellites of the Meteosat Second Generation (MSG) series. In this study we present a new collection of albedo satellite products based on the same satellite data. The MSG Ten-day ALbedo (MTAL) product incorporates MSG observations over 31 days with a frequency of NRT production of 10 days. The MTAL collection is more dedicated to climate analysis studies compared to the daily albedo that was initially designed for the weather prediction community. For this reason, a homogeneous reprocessing of MTAL was done in 2018 to generate a Climate Data Record (CDR). The resulting product is called MTAL-R and has been made available to the community in addition to the NRT version of the MTAL product which has been available for several years. The retrieval algorithm behind the MTAL products comprises three distinct modules: one for atmospheric correction, one for daily inversion of a semi-empirical model of the bidirectional reflectance distribution function, and one for monthly composition that also determines surface albedo values. In this study the MTAL-R CDR is compared to ground surface measurements and concomitant albedo products collected by sensors on-board polar-orbiting satellites (SPOT-VGT and MODIS). We show that MTAL-R meets the quality requirements if MODIS or SPOT-VGT are considered as reference. This work leads to 14 years of production of geostationary land surface albedo products with a guaranteed continuity in the LSA SAF for the future years with the forthcoming third generation of European geostationary satellites.
Benchmarking Current Capabilities for the Generation of Excitation and Photoionisation Atomic Data
Authors: Ramsbottom Catherine , Ballance Connor , Smyth Ryan , Conroy Andrew , Fernández-Menchero Luis , Turkington Michael , Keenan Francis
Published: June 2018

The spectra currently emerging from modern ground- and space-based astronomical instruments are of exceptionally high quality and resolution. To meaningfully analyse these spectra researchers utilise complex modelling codes to replicate the observations. The main inputs to these codes are atomic data such as excitation and photoionisation cross sections as well as radiative transition probabilities, energy levels and line strengths. In this publication the current capabilities of the numerical methods and computer packages used in the generation of these data are discussed. Particular emphasis is given to Fe-peak species and the heavy systems of tungsten and molybdenum. Some of the results presented to highlight certain issues and/or advances have already been published in the literature, while other sections present, for the first time, new recently evaluated atomic data.
Polyethylene Glycol (PEG) Exposure with Antihemophilic Factor (Recombinant), PEGylated (rurioctocog alfa pegol) and Other Parenteral Therapies Indicated for the Pediatric Population: History and Safety
Authors: Stidl Reinhard , Denne Michael , Goldstine Jimena , Kadish Bill , Korakas Katherine I. , Turecek Peter L.
Published: June 2018

Polyethylene glycol (PEG) is an inert, water soluble polymer, used for decades in pharmaceuticals. Although PEG is considered safe, concerns persist about the potential adverse effects of long-term exposure to PEG-containing therapies, specifically in children, following the introduction of PEGylated recombinant factor products used for the treatment of hemophilia. Given the absence of long-term surveillance data, and to evaluate the potential risk, we estimated PEG exposure in the pediatric population receiving US Food and Drug Administration-approved parenteral therapies with pediatric indications. We used a range of pediatric weights and doses based on prescribing information (PI) or treatment guidelines. PIs and reporting websites were searched for information about adverse events (AEs). For a child weighing 50 kg on the highest prophylactic dose of a FVIII product, the range of total PEG exposure was 40–21,840 mg/year; for FIX products, the range was 13–1342 mg/year; and for other products, the range was 383–26,743 mg/year, primarily as a derivative excipient. No AE patterns attributable to PEG were found for any of these products, including potential renal, neurological, or hepatic AEs. Our analyses suggest the pediatric population has had substantial exposure to PEG for several decades, with no evidence of adverse consequences.
Modeling Analytical Streams for Social Business Intelligence
Authors: Lanza-Cruz Indira , Berlanga Rafael , Aramburu María José
Published: June 2018

Social Business Intelligence (SBI) enables companies to capture strategic information from public social networks. Contrary to traditional Business Intelligence (BI), SBI has to face the high dynamicity of both the social network contents and the company analytical requests, as well as the enormous amount of noisy data. Effective exploitation of these continuous sources of data requires efficient processing of the streamed data to be semantically shaped into insightful facts. In this paper, we propose a multidimensional formalism to represent and evaluate social indicators directly from fact streams derived in turn from social network data. This formalism relies on two main aspects: the semantic representation of facts via Linked Open Data and the support of OLAP-like multidimensional analysis models. Contrary to traditional BI formalisms, we start the process by modeling the required social indicators according to the strategic goals of the company. From these specifications, all the required fact streams are modeled and deployed to trace the indicators. The main advantages of this approach are the easy definition of on-demand social indicators, and the treatment of changing dimensions and metrics through streamed facts. We demonstrate its usefulness by introducing a real scenario user case in the automotive sector.
CO2 Pipeline Design: A Review
Authors: Peletiri Suoton P. , Rahmanian Nejat , Mujtaba Iqbal M.
Published: June 2018

There is need to accurately design pipelines to transport the expected increase of CO2 captured from industrial processes after the signing of the Paris Climate Agreement in 2016. This paper reviews several aspects of CO2 pipeline design with emphasis on pressure drop and models for the calculation of pipeline diameter. Two categories of pipeline equations were identified. The first category is independent of pipeline length and has two different equations. This category is used to specify adequate pipeline diameter for the volume of fluid transported. The optimum economic pipe diameter equation (Eq. 17) with nearly uniform resultant velocity values at different flow rates performed better than the standard velocity flow equation (Eq. 20). The second category has four different equations and is used to calculate pipeline pressure drop or pipeline distance for the installation of booster stations after specifying minimum and maximum pipeline pressures. The hydraulic equation is preferred because it gave better resultant velocity values and the closest diameter value obtained using Aspen HYSYS (V.10) simulation. The effect of impurities on the pressure behaviour and optimal pipeline diameter and pressure loss due to acceleration were ignored in the development of the models. Further work is ongoing to incorporate these effects into the models.
A Scale-Invariant, Machian Theory of Gravitation and Electrodynamics Unified
Authors: Vishwakarma Ram Gopal
Published: June 2018

As gravitation and electromagnetism are closely analogous long-range interactions, and gravitation is formulated in terms of geometry in general relativity (GR), we expect the latter also to appear through the geometry. This unification has however remained an unfulfilled goal. The goal is achieved here in a new theory, which results from the principles of equivalence and Mach supplemented with a novel insight that the field tensors in a geometric theory of gravitation and electromagnetism must be traceless, since these long-range interactions are mediated by virtual exchange of massless particles whose mass is expected to be related to the trace of the field tensors. Hence the Riemann tensor, like the analogous electromagnetic field tensor, must be traceless. Thence emerges a scale- invariant, Machian theory of gravitation and electrodynamics unified, wherein the vanishing of the Ricci tensor appears as a boundary condition. While the field equations of the theory are given by the vanishing divergence of the respective field tensors and their duals, the matter and charge emerge from the spacetime. A quantitative formulation of the emergent fields embodied in ‘energymomentum super tensors’ follows from the respective Bianchi identities for the two fields. The resulting theory is valid at all scales and explains the observations without invoking the non-baryonic dark matter, dark energy or inflation. Moreover, it answers the questions that the GR-based standard paradigm could not address.
First Steps towards Data-driven Adversarial Deduplication
Authors: Paredes Jose , Simari Gerardo , Martinez Maria Vanina , Falappa Marcelo
Published: June 2018

In traditional databases, the entity resolution problem (which is also known as deduplication), refers to the task of mapping multiple manifestations of virtual objects to its corresponding real-world entity. When addressing this problem, in both theory and practice, it is widely assumed that such sets of virtual object appear as the result of clerical errors, transliterations, missing or updated attributes, abbreviations, and so forth. In this paper, we address this problem under the assumption that this situation is caused by malicious actors operating in domains in which they do not wish to be identified, such as hacker forums and markets in which the participants are motivated to remain semi-anonymous (though they wish to keep their true identities secret, they find it useful for customers to identify their products and services). We are therefore in the presence of a different, even more challenging problem that we refer to as adversarial deduplication. In this paper, we study this problem via examples that arise from real-world data on malicious hacker forums and markets arising from collaborations with a cyber threat intelligence company focusing on understanding this kind of behavior. We argue that it is very difficult---if not impossible---to find ground truth data on which to build solutions to this problem, and develop a set of preliminary experiments based on training machine learning classifiers that leverage text analysis to detect potential cases of duplicate entities. Our results are encouraging as a first step towards building tools that human analysts can use to enhance their capabilities towards fighting cyber threats.

Published: June 2018

This study aimed to evaluate the relationship between various asbestos exposure routes and asbestos-related disorders (ARDs). The study population comprised 11,186 residents of a metropolitan city who lived near asbestos factories, shipyards, or in slate roof-dense areas. ARDs were defined from chest X-rays indicating lower lung fibrosis (LFF), pleural disease (PD), and lung masses (LMs). Of the subjects, 11.2%, 10.4%, 67.2% and 8.3% were exposed to asbestos via occupational, household, neighborhood, and slate roof routes, respectively. Regarding adjusted confounders and other exposure routes, the odds ratio (OR) of PD from household exposure (i.e., living with asbestos-producing workers) was 1.9 (95% confidence interval: 0.9–4.2), and that of LLF and PD from neighborhood exposure, or residing near asbestos factories) for <19 or >20 years, or near a mine, were 4.1 (2.8–5.8) and 4.8 (3.4–6.7), 8.3 (5.5–12.3) and 8.0 (5.5–11.6), and 4.8 (2.7–8.5) and 9.0 (5.6–14.4), respectively. The ORs of LLF, PD, and LM among those residing in slate-dense areas were 5.5 (3.3–9.0), 8.8 (5.6–13.8), and 20.5 (10.4–40.4), respectively. Substantial proportions of citizens residing in industrialized city have potentially been exposed to asbestos, and various exposure routes are associated with the development of ARDs. Notably, this may be the first finding of the health effects of slate roof exposure. However, given the limitations of this study, including potential confounders such as socioeconomic status, further research is needed.

Markets from Maputo City have been reported to have poorly hygienic premises and sellers unaware of the safest food handling practices. This study aimed to analyze associations between some lettuce (Lactuca sativa) handling features and the levels of total, fecal coliforms and Escherichia coli. Cabbage was purchased in the 3 markets. Just before the acquisition, the researchers recorded the source of water used to wash it, if they were sold in booths or on the floor, if they were sold mixed with other products, and if the sellers were wearing gloves. The cabbage heads (42) were analyzed through the technique of multiple tubes to estimate the most probable number. Average levels were 14.43 MPN/g for total coliforms, 13.9 MPN/g for fecal coliforms and 12.02 MPN/g for E. coli. The highest levels of contamination seemed associated with the use of well water, the food sold on the floor, the lettuce sold together with other products and the lack of gloves. The mixture of products only showed a major impact on the level of E. coli (p < 0.001). Yet, all levels were within the satisfactory range, according to the guidelines from The International Commission on Microbiological Specifications for Foods (ICMSF).

External impact on the development of fluvial systems is generally exerted by changes in sea level, climate and tectonic movements. In this study it is shown that regional to local differentiation of fluvial response may be caused by semi-direct effects of climate change and tectonic movement, as for instance vegetation cover, frozen soil, snow cover and longitudinal gradient. Such semi-direct effects may be responsible for specific fluvial activity resulting in proper drainage patterns, sedimentation series and erosion-accumulation rates. These conclusions are exemplified by the study of the Tis(z)a catchment in the Pannonian Basin in Hungary and Serbia from the middle of the last glacial to the Pleistocene-Holocene transition. Previous investigations in that catchment are supplemented here by new geomorphological-sedimentological data and OSL-dating. Specific characteristics of this catchment in comparison with other regions are the preponderance of meandering systems during the last glacial and the presence of very large meanders in given time intervals.

Since the genomic era is a reality nowadays, we need deeper understanding and consideration upon the benefits and challenges it brings. Apart from all the enthusiasm, there are also concerns related to genomics, specifically to the use and storage of personal genetic information as well as concerns regarding, for instance, so-called incidental findings, and right not to know. It started with Mendel’s simple experiments, but led to high-throughput sequencing technologies, resulting complex genomic data is constantly poured into public and private databases, inevitably changing our current knowledge. With the advent of new techniques and methods, like CRISPR/Cas9 engineering, researchers are provided with improved and expanded repertoire of research tools to analyse an organism in health and disease. This paper is aimed at providing examples of the applications and challenges, both practical and theoretical, in exploring human genetic variation.

Whey proteins have excellent nutritional characteristics due to their levels of essential amino acids with high bioavailability. However, it has a high biochemical oxygen demand (BOD) and a considerable polluting potential, thus food manufacturers have opted to add whey to food formulations. The demand for beverages containing vitamins, probiotics, prebiotics, minerals, and bioactive compounds (antioxidants) with health benefits has increased and driven market growth. Therefore, this study aimed to develop a probiotic functional carbonated beverage from cheese whey and evaluate its microbiological, and physicochemical characteristics soon after the production and during storage. The viability and stability of probiotic, the microbiological characteristics, titratable acidity and sedimentation of the beverage were monitored during refrigerated storage for a month. The probiotic to be added to the formulation was established in a preliminary step. The production of this beverage proved to be a simple technology and the product was suitable for incorporation of the probiotic Bifidobacterium animalis subsp. lactis. The probiotic showed good viability and stability during storage. The microbiological quality of the beverage met the Brazilian legal standards. The pH and titratable acidity of the probiotic carbonated beverage remained stable during storage, and slight sedimentation was observed after one week of refrigerated storage.

Background: Chronic heart failure (CHF) is an inflammatory disorder in which cortisol plays an important role. Despite this, cortisol is not routinely quantitatively measured for a number of reasons. It is considered non-specific. Accuracy and validity remain in question. It is not considered convenient or cost effective. Finally, tissue level effects of cortisol do not correlate linearly to quantitative levels. If the functional, tissue level effectiveness of cortisol could be modeled, its evaluation in CHF patient may become relevant. Endobiogeny is a global systems theory that claims to be able to model complex physiology through biomarkers, offering context-rich interpretations of data for meaningful clinical applicability. Cortisol is known to alter circulating levels of elements from a complete blood count (CBC). By relating these biomarkers in a qualitative fashion, the theory of Endobiogeny posits that these elements can be contextualized to reflect the tissue level activity of cortisol, referred to as the cortisol index (CI). The algorithm derived from the theory is called the Biology of Functions (BoF). Aim: The aim of this study was to determine if the cortisol index is accurate in reflecting a greater expression of cortisol activity in ambulatory CHF patients versus controls subjects. Methods: A retrospective observational case control study was performed in 93 patients with New York Heart Association class II-III heart failure patients and 104 individuals with no cardiovascular pathology as a control group. Results from a CBC were entered into BOF modeling software, from which the cortisol index is derived. Results: The Cortisol index (3-7) was significantly elevated in CHF vs. control patients (12.8±0.91 vs. 8.48±0.74, p< 001), as were individual CBC elements used to form the index. Conclusions: The cortisol index, derived from the theory of Endobiogeny showed results consistent with CHF pathophysiology. The cortisol index was able to model the effective tissue level activity of cortisol in CHF patients using only a CBC, without measuring serum cortisol. Future studies should compare the cortisol index to standard inflammatory markers in CHF patients to further correlate the validity of the index to other known effects of cortisol.

Objectives: Acute coronary syndrome as an acute oxygenated blood deprivation to the heart muscle due to atherosclerotic plaque rupture in the coronary artery followed by thrombosis is possibly associated with changes in the Earth’s local time varying magnetic field as they strongly influence hormonal and other regulatory systems’ activity. This study analyses the correlation between prevalence of the acute coronary syndrome and the changes in the local time varying aspects of the magnetic field. Methods: Seven-hundred patients admitted to Cardiology Department of Hospital of Lithuanian University of Health Sciences Kaunas Clinics within 2016 due to acute coronary syndrome were retrospectively included into the study. The number of cases per week was compared with the weekly changes of the local Earth magnetic field. The one-year period was divided into two periods: the first-half of the year (weeks 1 to 26) and the second-half of the year (weeks 27 to 52) and more detailed analyses were performed accordingly to the significance of the left main artery lesion. Mean power of local magnetic field fluctuations in Lithuania, measured in pT2 in five different frequency ranges where overlaps between the Schumann resonance and EEG frequency ranges (named as SDelta (0-3.5 Hz), STheta (3.5-7 Hz), SAlpha (7-15 Hz), SBeta (15-32 Hz) and SGamma (32-66 Hz) to distinguish them from the EEG bands). Results: Statistically significant weak and moderate correlations between weekly prevalence of acute coronary syndrome admissions and the magnetic field intensities changes were found. Higher intensities in the SBeta and SGamma ranges were associated with a higher number of admissions throughout the year in females and the SGamma range was associated with higher number of admission only during the second-half of the year in males. A higher intensity magnetic field in SDelta, STheta, SAlpha and SBeta ranges was associated with a higher admissions number due to left main artery lesions in males, while a higher intensity in the SGamma range was associated with higher number of admissions due to left main artery lesions in females through the year. Conclusion: Significant correlation between acute coronary syndrome and changes in the local Earth time varying magnetic field intensities was found. Some frequency ranges are associated with an episode of an acute coronary syndrome. Left main artery lesions significantly correlated with magnetic field changes in most of the frequency ranges in males while only one of the frequency ranges in females.
