Serum and follicular fluid levels of soluble receptor for advanced glycation end-products in women with and without polycystic ovary syndrome
No full textAbstract Background Advanced glycation end products (AGEs) are known to associate with the pathogenesis of several chronic diseases via interaction with their corresponding receptor (RAGE). The soluble forms of RAGE (sRAGE) are considered as anti-inflammatory agents by inhibiting the consequent adverse effects of AGE. We aimed at comparing sRAGE levels in the follicular fluid (FF) and serum of women with or without Polycystic Ovary Syndrome (PCOS) who underwent controlled ovarian stimulation for in vitro fertilisation (IVF). Methods A total of forty-five eligible women (26 non-PCOS (control) and 19 patients with PCOS (case)) were included the study. sRAGEs in FF and blood serum were measured using ELISA kit. Results No statistically significant differences were found in FF and serum sRAGE between case and control groups. Correlation analysis showed a significant and positive relationship between serum levels of sRAGE and FF sRAGE in PCOS (r = 0.639; p = 0.004), in control participants (r = 0.481; p = 0.017), and in total participants (r = 0.552; p = 0.000). Data revealed a statistically significant difference in FF sRAGE concentration among all participants by body mass index (BMI) categories (p = 0.01) and in controls (p = 0.022). Significant differences were found for all the nutrients and AGEs consumption according to Food Frequency Questionnaire in both groups (p = 0.0001). A significant reverse relationship was found between FF levels of sRAGE and AGE in PCOS (r = -0.513; p = 0.025). The concentration of sRAGE in serum and FF is the same in PCOS and control. Conclusion The present study revealed for the first time that there are no statistically significant differences between the concentration of serum sRAGE and FF sRAGE among Iranian women with and without PCOS. However, BMI and dietary intake of AGEs have more significant effects on sRAGE concentration in Iranian women. Future studies in developed and developing countries with larger sample sizes are required to determine the long-term consequences of chronic AGE over consumption and the optimal strategies for minimizing AGE-related pathology, specifically in low income and developing countries
Competing in the RoboCup Rescue Robot League
No full textRoboCup Rescue is an international competition in which robots compete to find disaster victims in a simulated earthquake environment. It features both a Rescue Simulation League (RSL) which is entirely computer simulated, and a Rescue Robot League (RRL) with real robots and a test arena. This paper will describe the experience gained sending an undergraduate team to compete in the Rescue Robot League at the RoboCup German Open in 2008 and 2009. The design of the test arena and the rules of the competition will be outlined; as will the approaches taken by different teams; and the competition results
Low-energy standby-sparing for hard real-time systems
No full textTime-redundancy techniques are commonly used in real-time systems to achieve fault tolerance without incurring high energy overhead. However, reliability requirements of hard real-time systems that are used in safety-critical applications are so stringent that time-redundancy techniques are sometimes unable to achieve them. Standby sparing as a hardware redundancy technique can be used to meet high reliability requirements of safety-critical applications. However, conventional standby-sparing techniques are not suitable for low-energy hard real-time systems as they either impose considerable energy overheads or are not proper for hard timing constraints. In this paper we provide a technique to use standby sparing for hard real-time systems with limited energy budgets. The principal contribution of this work is an online energy management technique which is specifically developed for standby-sparing systems that are used in hard real-time applications. This technique operates at runtime and exploits dynamic slacks to reduce the energy consumption while guaranteeing hard deadlines. We compared the low-energy standby-sparing (LESS) system with a low-energy time redundancy system (from a previous work). The results show that for relaxed time constraints, the LESS system is more reliable and provides about 26% energy saving as compared to the time-redundancy system. For tight deadlines when the time redundancy system is not sufficiently reliable (for safety-critical application), the LESS system preserves its reliability but with about 49% more energy consumptio
Identifying and Optimizing Electric Vehicle Corridor Charging Infrastructure for Medium and Heavy-Duty Trucks
No full textThis project studies the benefits and barriers of increased adoption of medium-duty and heavy-duty electric trucks, referred to as e-trucks, and presents a methodology for optimizing the location of e-truck charging stations in Minnesota. In general, e-trucks provide zero tailpipe emissions and lower operating and maintenance costs. However, some barriers to adopting e-trucks include higher initial purchase costs, lack of charging and maintenance infrastructure, limited range, and charging time. The methods presented in this study aim to address the charging infrastructure planning, which provides information about e-truck charging activities, changes in vehicle miles traveled (VMT), and potential operating cost savings.Khani, Alireza; Emami, Behnam Davazdah; Garcia, Fernando; Popenhagen, Brandi.

Suicide as a Passage Through Silent Issues: A Case Study of Suicide Attempt Survivors in Tehran Zeinab Kouchakian Alireza Kaldi Alireza Mohsenitabrizi
No full textSuicide as a Passage Through Silent Issues: A Case Study of Suicide Attempt Survivors in Tehran Zeinab Kouchakian[1] , Alireza Kaldi[2] , Alireza Mohsenitabrizi[3] Received: 06/4/2018 Accepted: 22/12/2018 Abstract Suicide, as a conscious action in hurting oneself causing death, is among the social issues of human society that is increasing day by day. Suicide epidemiological studies inIran have shown that attempting suicide and committing an act of suicide is increasing. Using a qualitative approach, and based on the grounded theory of the social and cultural reasons behind suicide attempt, the current study aims to investigate the interaction between the person who commits suicide and his/her family, group and society as well as its relationship with suicide attempt. Through this, the present study seeks to find a more vivid image of the relationship between [1]. Ph.D. student of Cultural Sociology, Islamic Azad University, Science and Research Branch of Tehran.

Einfluss von Probiotika auf gesundes und erkranktes Parodont
No full textDie Gründe für die Entstehung einer Parodontitis sind nicht nur auf mangelhafte Mundhygiene, Ernährung, chronisch proinflammatorische Fehlregulation des mukosalen Immunsystems und genetische Disposition zurückzuführen, sondern auch auf eine unphysiologische Veränderung des Keimspektrums (Dysbiose) des humanen Mikrobioms der Mundhöhle. Die Modifikation des Mikrobioms durch den gezielten Konsum von Lebensmitteln mit gesundheitsfördernden Mikroorganismen bildet die Basis des Konzepts der probiotischen Therapie. Das Ziel dieser systematischen Überprüfung ist es zu bestimmen, ob die Verwendung von Probiotika klinische vorteilhafte Wirkungen bei der Prävention und Behandlung von Parodontalerkrankungen hat. In der systematischen Literaturübersicht in PubMed, Medline, Embase, Scopus und CENTRAL wird mit deskriptiven statistischen Mitteln die klinische Effektivität der Probiotika mit normaler parodontaler Basistherapie (Scaling and Root Planing), Chlorhexidin (oder andere Medikamente) oder Placebo verglichen. Dabei werden unterschiedliche klinische Parameter wie Plaque Index (PI), Gingival Index (GI), Bleeding on Probing (BOP), Sondierungstiefe (PD) und Clinical Attachement Level (CAL) betrachtet. Es lagen im Zeitraum der Literaturrecherche 29 randomisierte, veröffentlichte klinische Studien (RCTs) zum Thema "Einfluss von Probiotika auf gesundes und erkranktes Parodont" vor.
Zehn Studien wurden nach der Analyse der vollständigen Texte aus 29 klinischen Studien eingeschlossen.
Zur Einschätzung der praktischen Bedeutung die Effektstärke nach Cohen (Cohens d) berechnet. Zum besseren Vergleich der Daten werden grafische Darstellungen eingesetzt. Als Fehlerindikatoren werden die Standardabweichungen in die Balken eingezeichnet. Der Mittelwert über alle Stichproben wird nach den Fallzahlen gewichtet.
Die vorhandenen Studien zeigen mehrheitlich eine signifikante Verbesserung der objektiven Ergebnisse der Parameter PI und PPD bei Testgruppe (Probiotika) im Vor- und Nachbehandlungen Vergleich mit Placebogruppe, jedoch zeigen der Parameter GI, BOP und CAL keine eindeutigen Ergebnisse. Diese Hinweise sollten durch große und qualitativ hochwertige, randomisierte kontrollierte Studien (RCTs) überprüft werden.The reasons for development of periodontitis are not only attributable to inadequate oral hygiene, nutrition, chronic pro-inflammatory dysregulation of the mucosal immune system and genetic disposition, but also to an un-physiological change of the bacterial spectrum (dysbiosis) of the human microbiome in the oral cavity. The development of key germs through specific consumption of foodstuffs with health-promoting microorganisms forms the basis of the probiotic therapy concept.
The goal of this systematic review is to determine whether the use of probiotics has clinically advantageous effects with regard to the prevention and treatment of periodontal diseases. The clinical effectiveness of probiotics with normal basic periodontal therapy (scaling and root planing), chlorhexidine (or other medications) or placebo is compared with descriptive statistical means in the systematic literature survey available in PubMed, Medline, Embase, Scopus and CENTRAL. Various clinical parameters such as plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD) and clinical attachment level (CAL) are considered in this regard.
Twenty nine randomised, controlled trials (RCTs) published on the topic "influence of probiotics on healthy and diseased periodontium" were available in the period of literature research.
Ten studies were included after the analysis of complete texts from 29 clinical trials.
The practical significance of effect size according to Cohen (Cohen's d) was calculated for assessment. Graphic representations were used for better comparison of data. Standard deviations were mapped in the bars as error indicators. The mean value of all samples is weighted according to the case numbers.
The majority of existing studies show a significant improvement in the objective results of the parameters PI and PPD (pocket probing depth) among the test group (probiotics) during pre-treatment and follow-up treatment compared to the placebo group, however show the parameters GI, BOP and CAL inconclusive results. These indications should be reviewed by means of large, randomised controlled trials (RCTs) of high quality.eingereicht von Alireza Emami NouriAbweichender Titel laut Übersetzung der Verfasserin/des VerfassersZusammenfassung in engl.
