Hidradenitis Süpürativada Cerrahi Tedavinin Başarısı: Geniş Ve Derin Cerrahi Eksizyon
Authors: Bilgen Fatma , Ural Alper , Bekerecioğlu Mehmet
Published: March 2018

Amaç:
 Hidradenitis süpürativa apokrin ter
bezlerinde yerleşen ağrılı, akıntılı apse oluşumları, sinüs, fistül ve skarlar
ile çevre dokulara yayılan tekrarlayıcı bir hastalıktır. Etyolojisi kesin olarak bilinmemekle birlikte
genetik yatkınlık, hormonal faktörler, obezite ve sigara kullanımı suçlanan
faktörlerdir. Erken dönem lezyonlara medikal tedavi uygulanırken, kronik,
komplike olgularda tedavi cerrahidir. Bununla birlikte nüksler görülebilir ve
reeksizyon gerekebilir. Bu çalışmada farklı anatomik bölgelerde bulunan ve
klinik olarak farklı güvenlik sınırıyla eksizyon uygulanmış hidradenitis süpürativa
olgularındaki nüks ve diğer komplikasyon oranlarının araştırılması
amaçlanmıştır.

Gereç
Ve Yöntemler: Bu çalışmada Ocak 2000- Mart 2017 tarihleri arasında plastik
cerrahi polikliniğine müracat eden, medikal tedaviye dirençli, kronik,
rekürrens gösteren ve cerrahi tedavi uygulanan 45 hasta lezyonların yerleşim
yeri, uygulanan cerrahi yöntemler ve komplikasyonlar açısından retrospesifik
olarak değerlendirildi. Hastaların 25’i erkek, 20’si kadın ve yaş ortalaması 36,7
idi (15–78).  

Bulgular
: Hidradenitis süpürativalı hastaları tedaviye yönlendiren temel sebep yaşam
kalitesinin bozulması ve psikolojik sorunlara kadar uzanan sağlık problemlerine
sebep olmasıdır. Hidradenitis süpürativa’da tedavi hastalığın bulguları ve
derecesine göre belirlenir. Erken evre hastalara genellikle medikal tedaviler
uygulanırken ilerlemiş vakalarda geniş cerrahi eksizyon gerekmektedir.

Sonuç:
İntermammarial bölgede lezyonu olan 2 hastada ve perianal yerleşimli lezyonu
olan 3 hastada lezyon sınırında  yapılan
eksizyonlar sonrası nüks görüldü. Toplamda hastalarda nüks oranı %11,1 olarak
tespit edildi ve bu hastalara daha geniş cerrahi sınırla reeksizyon yapıldı. Bu
çalışmanın amacı hidradenitis süpürativa tedavisinde geniş ve derin cerrahi
eksizyonu önemini vurgulamaktır.
Sociolinguística, teoria social e padronização linguística
Authors: Santos Marcos Bispo
Published: March 2018

Resumo: Neste artigo, questiona-se a pertinência e a relevância da sociolinguística variacionista como ciência aplicada na abordagem de questões relativas à padronização linguística no Brasil. Para isso, fez-se uma pesquisa bibliográfica dividida em dois eixos, o linguístico e o sociológico, com o intuito de compreender as bases teóricas da sociolinguística brasileira. No primeiro eixo, buscou-se compreender a natureza da sociolinguística com base nas pesquisas de Labov. No segundo, situou-se o componente propriamente sociológico da sociolinguística no contexto das teorias sociais. A análise evidenciou que a metodologia da pesquisa, no contexto da sociolinguística variacionista, é marcadamente positivista e não se coaduna com os princípios da pesquisa social contemporânea. Verificou-se ainda que a tese da ideologia dominante, elemento central da teoria social da sociolinguística brasileira, além de não exercer influência significativa na metodologia da pesquisa, já foi amplamente questionada e não exerce influência na pesquisa social contemporânea.Palavras-chave: padronização linguística; sociolinguística variacionista; teoria social.Abstract: In this article, we discuss the pertinence and relevance of Brazilian variationist sociolinguistics as applied science in the approach of issues related to linguistic standardization. In order to do so, we conducted a bibliographical research divided into two axes, the linguistic one and the sociological one, aiming at understanding the theoretical bases of Brazilian sociolinguistics. In the first axis, we discussed the nature of sociolinguistics taking Labov’s research as a starting point. Then, we situated the sociological component of sociolinguistics in the context of Social Theories. The analysis showed that in the context of variationist sociolinguistics, the research methodology is markedly positivist and does not conform to the principles of contemporary social research. We also observed that the Dominant Ideology Theory, a central element in the social theory of Brazilian sociolinguistics, not only did not exert significant influence in the methodology of the research works carried out in the area, but also had already been widely questioned in the context of social research and does not present satisfactory answers to the problems it is supposed to explain.Keywords: linguistic standardization; variacionist sociolinguistics; social theory.
Aprender colocaciones en español: utilización de tres repertorios en estudiantes de español
Authors: Alba Quiñones Virginia
Published: March 2018

El estudio trata de analizar la influencia que dos Diccionarios monolingües de aprendizaje y un diccionario combinatorio pueden presentar en el desarrollo de la competencia colocacional léxica en un grupo de 97 aprendices universitarios de español como lengua extranjera con diferentes niveles de domino lingüístico. Para ello, se diseñó una prueba, así se presentaron diez enunciados con colocaciones del tipo verbo + sustantivo (OD) donde se había elidido el colocativo y los estudiantes en dos fases tuvieron que rellenar el hueco: en la primera sin la ayuda de los repertorios lexicográficos y en la segunda haciendo uso de ellos. Los resultados del presente estudio no dejan lugar a dudas, ya que el dominio colocacional de los estudiantes aumentó de manera considerable en todos los niveles.
Los sentidos humanos ¿«conservados u olvidados»?
Authors: Beltran Vicenç
Published: March 2018

Un pasaje de las Coplas de Jorge Manrique a la muerte de su padre alterna las lecturas equipolentes «sentidos conservados» y «sentidos olvidados», de las que en mi edición crítica elegí la segunda por contener «sentidos» la acepción ‘apetitos’ según el Diccionario de Autoridades. Tras un artículo de J. C. Conde donde se ponía en duda su existencia y, por ende, mi elección en el texto crítico, una exploración de la filosofía y la teología medieval de los sentidos en latín y romance y de las formulaciones léxicas que recibió en la tratadística castellana induce a aceptar la existencia de dicha acepción y, por ende, de la variante entonces elegida.

Risk management and prevention methodologies: a comparison
Authors: Acevedo Nancy , Satizábal Cristina
Published: March 2018

In this paper we analyze nine risk management and prevention methodologies, carrying out a comparison of the stages that they include and determining if they take into account the human factor in the risk analysis and treatment. We observe that only 42.85% of the studied management risk methodologies include this factor and conclude that the NIST [National Institute of Standards and Technology] Risk Management methodology is the most complete, although it would be desirable for it to focus more on the human factor like the IDB [Inter-American Development Bank] Corruption Diagnosis, Prevention and Control in Programs of Civic Security methodology.

The results recorded at the end of the practices with this group of students, especially when assessing the progressive use of abstraction mechanisms in the Scratch environment, are presented, using the Dr. Scratch platform.
Framework for malware analysis in Android
Authors: Urcuqui-López Christian , Navarro Cadavid Andrés
Published: March 2018

Android is a open source operating system with more than a billion of users, including all kind of devices (cell phones, TV, smart watch, etc). The amount of sensitive data “using” this technologies has increased the cyber criminals interest to develop tools and techniques to acquire that information or to disrupt the device's smooth operation. Despite several solutions are able to guarantee an adequate level of security, day by day the hackers skills grows up (because of their growing experience), what means a permanent challenge for security tools developers. As a response, several members of the research community are using artificial intelligence tools for Android security, particularly machine learning techniques to classify between healthy and malicious apps; from an analytic review of those works, this paper propose a static analysis framework and machine learning to do that classification.
Architectural approach for automatic follow up of learning activities in massive open online courses
Authors: Jaramillo Morillo Daniel Alberto , Solarte Sarasty Mario Fernando
Published: March 2018

Currently it has been generated great interest in the massive open online courses, because they are consider as an “educational revolution”, since they are presented as a solution to the growing demand for higher education both in Colombia and in the world. Their main objective is to achieve a high volume of participants, allowing a global reach and a more participative learning. However, as advantages arise due to their massiveness, a number of problems or challenges are also generated. One of the main difficulties that characterize this type of courses is the lack of a suitable relationship between tutor and students, since it is impossible that tutors have a personal relationship with each of the thousands of participants. Therefore certain types of activities such as assessment and monitoring get more difficult impacting the quality of learning. In this article, it is proposed an architectural approach for tracking learning activities, which is intended to improve tutor-student relationship in an environment of massiveness to maximize the quality of learning in massive open online courses.

Published: March 2018

Aim: The objective was to evaluate oral health-related quality of life (OHRQOL) in patients aging 18 - 60 years, considering oral health, dental aesthetic impact and self-esteem. Methods: The sample comprised 81 patients, regardless gender/ethnicity, seeking for dental aesthetic treatment at University São Francisco, Bragança Paulista-SP. The instruments used to assess the OHRQOL were the questionnaires: 1. Rosenberg Self-Esteem Scale (RSS); 2. Oral Health Impact Profile-14 Brazil (OHIP) and 3. Psychosocial Impact and Aesthetic Dental Questionnaire-Brazil (PIADQ). Data were analyzed by Spearman correlation (α=5%) and descriptive statistics. Results: The older the patient the worse the oral and general health conditions found (p<0.05). Moreover, the age showed significant correlation with OIHP and PIADQ questionnaires scores (p=0.000). The three questionnaires showed moderate positive correlations (p<0.05 r=0.461 – 0.685) among them. In addition, OHIP and QIPED questionnaires correlated with general health and oral health (p<0.05 r=0.230–0.558). Conclusion: It could be concluded that aesthetic dental needs interfere, in fact, in the oral health-related quality of life and in the self-steem of patients seeking for treatment University São Francisco Dental School.

Published: March 2018

Aim: To determine the current trends in technological armamentarium and endodontic treatment among Brazilian endodontists. Methods: A total of 279 endodontists answered a web-based survey questionnaire about their region of activity in Brazil and years as a specialist, average number of endodontic cases treated per month, number of visits to complete the treatment, use of rubber dam for isolation, type of irrigant, obturation technique and device used for this purpose, temporary filling materials, and greater difficulty encountered during treatment and technological armamentarium. A descriptive analysis, expressed in terms of frequency and percentage, was performed and the data were correlated using the chi-square test (p0.05). Results: Most of the respondents had up to 10 years as specialists. More than 50% of endodontists preferred to complete the endodontic treatment in a single visit. Ninety-nine percent of endodontists used rubber dam for isolation. NaOCl was the most widely used irrigant. Most of the respondents associated different techniques for root canal filling. Lateral condensation and Continuous wave of condensation were the isolated technique most reported. Filling devices (thermocompactors) were used by 53% of endodontists. Glass ionomer was the preferred temporary filling material. The answers for the use of technological armamentarium revealing that 94% of endodontists used an apex locator; 67.38% utilized magnification (loupe: 23.66%; microscope: 35.48%; microscope and loupe: 8.24%); 58% reported to digital radiography; and 47.31% used computed tomography as a complementary tool. About mechanized instrumentation, 44.44% endodontists employed rotary and reciprocating files. The difficulties encountered during endodontic treatment were classified as preparation > access > obturation > anesthesia > isolation. Conclusions: Most endodontists have implemented new technologies, such as mechanical instrumentation, apex locators, magnification, digital radiography, computed tomography, ultrasound, and obturation tools, in their clinical practice.

Published: March 2018

Aim: The propagation of S. aureus in hospital and dental environments is considered an important public health problem since resistant strains can cause serious infections in humans. The genetic variability of 99 oxacillin-resistant S. aureus isolates (ORSA) from the dental patients (oral cavity) and environments (air) was studied by isoenzyme genotyping. Methods: S. aureus isolates were studied using isoenzyme markers (alcohol dehydrogenase, sorbitol dehydrogenase, mannitol-1-phosphate dehydrogenase, malate dehydrogenase, glucose dehydrogenase, D-galactose dehydrogenase, glucose-6-phosphate dehydrogenase, catalase and /-esterase) and genetic (Nei’s statistics) and cluster analysis (UPGMA algorithm). Results: A highly frequent polyclonal pattern was observed in this population of ORSA isolates, suggesting various sources of contamination or microbial dispersion. Genetic relationship analysis showed a high degree of polymorphism between the strains, and it revealed three taxa (A, B and C) distantly genetically related (0.653dij1.432) and fifteen clusters (I to XV) moderately related (0.282dij0.653). These clusters harbored two or more highly related strains (0dij0.282), and the existence of microevolutionary processes in the population of ORSA. Conclusion: This research reinforces the hypothesis of the existence of several sources of contamination and/or dispersal of ORSA of clinical and epidemiologically importance, which could be associated with carriers (patients) and dental environmental (air).
Saliva Leptin Levels in Tooth Movement during Initial Stage of Orthodontic Alignment: A Pilot Study
Authors: Bakar Noraini Abu , Kamil Wisam , Al Bayati Lina , Mustafa Basma Ezzat
Published: March 2018

Introduction: During orthodontic tooth movement, the early response of periodontal tissues to mechanical stress is an acute inflammatory reaction. Mechanical stress from orthodontic appliances is believed to induce cells in the periodontal ligament (PDL) to form biologically active substances, such as enzymes and cytokines, responsible for connective tissue remodeling (Nishijima Y et al 2006). Leptin, a polypeptide hormone has been classified as a cytokine (Zhang et al 1994). Earlier findings concluded that leptin at high local concentrations protects the host from inflammation and infection as well as maintaining bone levels. It has been also suggested that leptin plays a significant role in bone formation by its direct effect on osteoblasts (Alparslan et al 2010). This pilot study aimed to study leptin in saliva and its association with tooth movement during initial orthodontic alignment. Objectives: To determine if there are any differences in saliva leptin level before and after orthodontic alignment. Material and methods: Ten orthodontic patients (7 girls and 3 boys; mean age, 16.76 ± 1.1 years) with crowding (up to 5mm) that required orthodontic fixed appliances, on a non-extraction basis as part of the treatment plan, were recruited in this longitudinal study. Orthodontic study models were constructed at baseline and at 6- weeks after orthodontic treatment commenced. Full fixed orthodontic appliances with initial 0.014” Nickel Titanium archwire placed. The amount of crowding was measured, before and after initial alignment with an electronic digital caliper (Max-Cal, Japan Micrometer Ltd, Tokyo, Japan) with an accuracy of up to 0.01mm. Unstimulated morning saliva sample were collected at all visits, after at least an 8-hour period of fasting and no-toothbrushing. After centrifugation (4000x g;10min), the samples were stored at -25C and tested using Leptin Abnova LEP Human ELISA kit (KA3080) which was subsequently analyzed. Subjects’ periodontal health status was also monitored throughout the study. Ethical approval (ID IREC 262) was received on 7th April 2014 from International Islamic University Malaysia Research Ethics Committee (IREC). Results: Leptin concentration in saliva was significantly decreased in a time-dependant manner (t(9)=8.60, p<0.001), from before orthodontic treatment (7016.45± 425.15 pg/mL) and 6 weeks after bond-up (4901.92±  238.64 pg/mL). Conclusion: Leptin concentration in saliva is decreased during orthodontic tooth movement in initial alignment stage.

Published: March 2018

O presente estudo buscou descrever a situação de segurança alimentar vivenciada por famílias residentes na comunidade rural de Galheiros do município de Diamantina, situada no Alto Vale do Jequitinhonha, no Estado de Minas Gerais, Brasil. Foi utilizada a Escala Brasileira de Insegurança Alimentar - EBIA - com 15 questões que refletem a insegurança alimentar em diferentes níveis de intensidade. Foram investigadas 28 famílias, e obtidas informações sobre renda familiar, renda per capita, condição sócio econômica, de moradia, de saneamento básico e consumo alimentar. A prevalência de insegurança alimentar encontrada na comunidade foi de 46,4%, sendo 32,14% leve, 3,6% moderada e 10,7% grave. Mais da metade das famílias (57,2%) viviam com o equivalente a ½ do salário mínimo por mês. A maioria das famílias (75,0%) relatou gastar com alimentação valores inferiores a R$ 350,00, e 53,6% relataram receber da união e/ou Estado algum tipo de benefício. Estes resultados demonstram que apesar de existir no Brasil políticas públicas de combate à fome, grande parte das famílias residentes em Galheiros, vive em vulnerabilidade social, assim sendo, são necessárias ações estruturantes para reverter tal quadro, tanto no que se refere à produção de alimentos, quanto ao acesso a alimentos em qualidade e quantidade suficiente.
The Development of Hadith Study Controversy in Indonesia: A Study of Miṣbāḥ al-Ẓulām by Muhajirin Amsar al-Dari
Authors: Fatihunnada Fatihunnada
Published: March 2018

There has been a wide presumption that hadith literature authored by Indonesian Muslim scholars is simple and static. This article challenges this view. It examines Miṣbāḥ al-Ẓulām, a commentary of Bulūg al-Marām, by Muhajirin Amsar al-Dari to show the dynamic development of the study on ikhtilāf al-ḥadīth (disputes over hadith). Grounded in the hermeneutic approach, this article argues that the development of hadith studies in Indonesia from time to time is not as simple as the general presupposition entails. This article shows that the development of hadith studies is raised following the provision of studies on ikhtilāf al-ḥadīth. The tradition of writing hadith in Indonesia began in the 17th century and, as a result, a number of hadith literatures have been produced by Indonesian Muslim scholars. This development challenges some scholars’ perception that the studies of hadith in Indonesia remain simple and the science of hadith in the country is hardly available.
Broadening of the Neutral Helium 492 nm Line in a Corona Discharge: Code Comparisons and Data Fitting
Authors: Sheeba Roshin Raj , Koubiti Mohammed , Bonifaci Nelly , Gilleron Franck , Pain Jean-Christophe , Stambulchik Evgeny
Published: March 2018

Passive plasma spectroscopy is a well-established non-intrusive diagnostic technique. Depending on the emitter and its environment which determine the dominant interactions and effects governing emission line shapes, passive spectroscopy allows the determination of electron densities, emitter and perturber temperatures as well as other quantities like abundances. However, using spectroscopy needs appropriate line shape codes retaining all the physical effects governing the emission line profiles. This requires for line shape code developers to continuously correct or improve them to increase their accuracy when applied for diagnostics. This is exactly the aim expected from code-code and code-data comparisons. In this context, the He I 492 nm emitted in a helium corona discharge at room temperature represents an ideal case since its profile results from several broadening mechanisms: Stark, Doppler, resonance and van der Waals. The importance of each broadening mechanism depends on the plasma parameters. Here the profiles of the He I 492 nm in a helium plasma computed by various codes are compared for a selected set of plasma parameters. In addition, preliminary results related to plasma parameter determination using experimental spectra from a helium corona discharge at low pressure 1- 2 bars, are presented.
Tumbling-Snake Model for Polymeric Liquids Subjected to Biaxial Elongational Flows with a Focus on Planar Elongation
Authors: Stephanou Pavlos S. , Kröger Martin
Published: March 2018

We have recently solved the tumbling-snake model for concentrated polymer solutions and entangled melts in the presence of both steady-state and transient shear and uniaxial elongational flows, supplemented by a variable link tension coefficient. Here, we provide the transient and stationary solutions of the tumbling-snake model under biaxial elongation both analytically, for small and large elongation rates, and via Brownian dynamics simulations, for the case of planar elongational flow over a wide range of rates, times, and the model parameters. We show that both the steady-state and transient first planar viscosity predictions are similar to their uniaxial counterparts, in accord with recent experimental data. The second planar viscosity seems to behave in all aspects similarly to the shear viscosity, if shear rate is replaced by elongation rate.

Published: March 2018

Glutamine is the main amino acid which is substrate for gluconeogenesis in postoperative period. It is suggested that this leads to a substantial and a long-term decline in glutamine concentration. Glutamine is a source of energy for the synthesis of nucleotides, lymphocytes and cells of gastrointestinal tract. In this study, 79 patients were qualified to a coronary artery bypass surgery (Group I) or a surgery in the large intestine area (Group II). The objectives of this study were: evaluation of the impact of surgical procedures on the serum concentration of glutamine of the operated patients, assessment of gender, weight and BMI impact on glutamine concentration and analysis of the correlation between glutaminę serum concentration and laboratory parameters. The mean concentration of glutamine before surgery, the 3rd and 5th day after surgery was higher in Group I. CRP level in the 3rd and 5th postoperative day was higher in Group II. There were no significant differences betweengroups when it comes to BMI and the concentration of CRP (p <0.05). Glutamine concentration depends on the severity of inflammation, the operated body cavity and the intensified catabolism which results from different pathophysiology of digestive system diseases and coronary arterial disease.

Published: March 2018

Environmental deterioration factors are constantly increasing, causing unwanted aesthetic changes to stone artworks due to exposure to various physical and chemical deterioration factors. Inorganic nanoparticle-filled polymer composites have extended their multiple functionalities to various applications, including cultural heritage conservation. Therefore, this study has examined the effects of clay, SiO2, Ca(OH)2 and CaCO3 nanomaterials in the enhancement of the physicomechanical properties of limestone monuments, the aim of the present work being to evaluate comparatively the effectiveness of nanoparticles as consolidation and protection material for limestone artworks. The nanoparticles were added to an acrylic-based copolymer (polyethylmethacrylate (EMA)/methylacrylate (MA) (70/30), in order to improve its physiochemical and mechanical properties, and produced a significant improvement in the ability of the polymers to consolidate and protect the stone. The synthesis process of nanoparticles/polymer nanocomposite has been prepared by an in situ emulsion polymerization system. The nanocomposites contained poly (EMA/MA) with a solid content of 3% [poly (EMA/MA)] in the absence and presence of 5% nanoparticles (0.15 g nanoparticles). Samples were subjected to artificial aging by relative humidity/temperature and acid/salt crystallization weathering to show the optimum conditions of durability and the effectiveness of the nano-mixture in improving the physical and mechanical properties of the stone material. To ensure that the treatment had no negative effects on the physical characteristics of the limestone, the properties of the treated limestone samples were evaluated comparatively before and after artificial aging by the conduct of microstructural (phase morphology studied by means of scanning electron microscopy) and aesthetic (colour and lightness measured by spectrophotometry) analyses. Also used were measurement of static contact angle of water droplets on the surface of the samples, total immersion water absorption, compressive strength, and abrasion resistance test. Results demonstrated that the addition of nanoparticles to an acrylic-based polymer enhanced its capability to consolidate and protect the limestone samples.
Fault-Tolerant Control for ROVs Using Control Reallocation and Power Isolation
Authors: Capocci Romano , Omerdic Edin , Dooly Gerard , Toal Daniel
Published: March 2018

This paper describes a novel thruster fault-tolerant control system (FTC) for open-frame remotely operated vehicles (ROVs). The proposed FTC consists of two subsystems: a model-free thruster fault detection and isolation subsystem (FDI) and a fault accommodation subsystem (FA). The FDI subsystem employs fault detection units (FDUs), associated with each thruster, to monitor their state. The robust, reliable and adaptive FDUs use a model-free pattern recognition neural network (PRNN) to detect internal and external faulty states of the thrusters in real time. The FA subsystem combines information provided by the FDI subsystem with predefined, user-configurable actions to accommodate partial and total faults and to perform an appropriate control reallocation. Software-level actions include penalisation of faulty thrusters in solution of control allocation problem and reallocation of control energy among the operable thrusters. Hardware-level actions include power isolation of faulty thrusters (total faults only) such that the entire ROV power system is not compromised. The proposed FTC system is implemented as a LabVIEW virtual instrument (VI) and evaluated in virtual (simulated) and real-world environments. The proposed FTC module can be used for open frame ROVs with up to 12 thrusters: eight horizontal thrusters configured in two horizontal layers of four thrusters each, and four vertical thrusters configured in one vertical layer. Results from both environments show that the ROV control system, enhanced with the FDI and FA subsystems, is capable of maintaining full 6 DOF control of ROV in the presence of up to 6 simultaneous total faults in the thrusters. With the FDI and FA subsystems in place the control energy distribution of the healthy thrusters is optimised so that the ROV can still operate in difficult conditions under fault scenarios.
Transcriptomic Analysis of Gonadal Adipose Tissue in Male Mice Exposed Perinatally to 2,2′,4,4′-Tetrabromodiphenyl Ether (BDE-47)
Authors: Abrha Aser , Suvorov Alexander
Published: March 2018

For the majority of lipophilic compounds adipose tissue is traditionally considered as storage depot and only rarely as a target organ. Meanwhile, abnormalities in adipose tissue physiology induced by chemical exposures may contribute to the current epidemic of obesity and metabolic diseases. Polybrominated diphenyl ethers (PBDEs) is a group of lipophilic flame retardants found in majority of human samples in North America. Their ability to alter physiology of adipose tissue is unknown. We exposed pregnant mice to 0.2 mg/kg body weight/day of BDE-47 perinatally. Transcriptomic changes in gonadal adipose tissue were analyzed in male offspring using RNA-seq approach with subsequent bioinformatic analysis. Genes of coagulation and complement cascade, de novo lipogenesis, and xenobiotic metabolism were altered in expression in response to BDE-47 exposure. The affected molecular network included the following hubs: PPARα, HNF1A and HNF4. These findings suggest that adipose tissue should be considered a target tissue for BDE-47, in addition to its role as a storage depot. This study also builds a background for a targeted search of sensitive phenotypic endpoints of BDE-47 exposure, including lipid profile parameters and coagulation factors in circulation. Additional studies are needed to investigate the role of PBDEs as an obesogen.

Published: March 2018

1) Background: we have evaluated the antihypertensive effect of several flavonoid extracts in a rat model of arterial hypertension caused by chronic administration (6 weeks) of the nitric oxide synthesis inhibitor, L-NAME. 2) Methods: Sprague Dawley rats received L-NAME alone or L-NAME plus flavonoid-rich vegetal extracts (Lemon, Grapefruit + Bitter Orange, and Cocoa) or purified flavonoids (Apigenin and Diosmin) for 6 weeks. 3) Results: L-NAME treatment resulted in a marked elevation of blood pressure, and treatment with Apigenin, Lemon Extract, and Grapefruit + Bitter Orange extracts significantly reduced the elevated blood pressure of these animals. Apigenin and some of these flavonoids also ameliorated nitric oxide-dependent and independent aortic vasodilation and elevated nitrite urinary excretion. End-organ abnormalities such as cardiac infarcts, hyaline arteriopathy and fibrinoid necrosis in coronary arteries and aorta were improved by these treatments, reducing the end-organ vascular damage. 4) Conclusions: the flavonoids included in this study, specially apigenin, may be used as functional food ingredients with potential therapeutic benefit in arterial hypertension.

Introduction: Lyme disease is a tickborne illness that generates controversy among medical providers and researchers. One of the key topics of debate is the existence of persistent infection with the Lyme spirochete, Borrelia burgdorferi, in patients who have been treated with recommended doses of antibiotics yet remain symptomatic. Persistent spirochetal infection despite antibiotic therapy has recently been demonstrated in non-human primates. We present evidence of persistent Borrelia infection despite antibiotic therapy in patients with ongoing Lyme disease symptoms. Materials & Methods: In this pilot study, culture of body fluids and tissues was performed in a randomly selected group of 12 patients with persistent Lyme disease symptoms who had been treated or who were being treated with antibiotics. Cultures were also performed on a group of 10 control subjects without Lyme disease. The cultures were subjected to corroborative microscopic, histopathological and molecular testing for Borrelia organisms in four independent laboratories in a blinded manner. Results: Motile spirochetes identified histopathologically as Borrelia were detected in culture specimens, and these spirochetes were genetically identified as Borrelia burgdorferi by three distinct polymerase chain reaction (PCR) methods. Spirochetes identified as Borrelia burgdorferi were cultured from the blood of seven subjects, from the genital secretions of ten subjects, and from a skin lesion of one subject. Cultures from control subjects without Lyme disease were negative for Borrelia using these methods. Conclusions: Using multiple corroborative detection methods, we showed that patients with persistent Lyme disease symptoms may have ongoing spirochetal infection despite antibiotic treatment, similar to findings in non-human primates. The optimal treatment for persistent Borrelia infection remains to be determined.

Ultra-thin Fe–6.5wt.%Si ribbons with 35 μm in thickness were prepared by melt-spinning. The magnetic properties were investigated before and after annealing 1000 ºC. DC properties and low-frequency (400 Hz ~ 10 kHz) iron losses have significantly improved after heat treatment. A simplified formula based on Steinmetz law which can be used to predict the AC iron loss is presented. According to the results of some iron losses data, a simplified formula has been determined, and the extent of AC iron losses can be predicted. The results obtained from the formula predict AC iron loss to a good degree. The method developed in this work could be extended to other magnetic materials for predicting AC iron loss with greater ease.
