Effects of Non-Focused Elf-Emf Treatment on Hrv: Preliminary Study

Background: The Autonomic Nervous System (ANS) is involved in the response to various emotional stimuli like anxiety, stress, and the sense of wellbeing. As a control system the ANS plays a variety of roles in humans, including regulation of the cardiac function, which can be studied by analyzing heart rate variability (HRV). HRV coherence has been associated with a sense of wellbeing, along with enhanced cognitive, social, and physical performance. Extremely low frequency electromagnetic fields (ELF-EMF) are used in a variety of clinical areas, however very little is known to date about the functional mechanisms involved in vivo . An interaction with the ANS is one of the possible ways in which the effects of ELF-EMF therapy are modulated in liv ing systems. ANS electromagnetic configurations meas uring the HRV using a HeartMath® EmWave® in age were recruited and divided into two groups (treatment group µ and control group λ). After measuring the baseline HRV coherence state (ω) the subjects in group µ were as sessed during administration of 5 different ELF-EMF configu rations from a SEQEX® device, all at the same intensity of 20 μT (the name attributed to the configuration is in brackets) for a duration of 3 min. each: 1-3 Hz (δ), 4-8 Hz (θ), 9-13 Hz (α), 15-29 Hz (β), and 31-56 Hz (γ). The subjects in group λ were measured in the same way and the same number of times. Results: The initial coherence values ω were comparable be tween the two groups (µ: 36%, λ: 36.39%). Under the 1-3 Hz (δ) and 15-29 Hz (β) treatment configurations, group µ had an average HRV coherence of 46.26% and 47.26% respec-tively, while group λ had 38.13% and 37.39% respectively, representing a significant increase in HRV coherence under treatment (p δ = 0.035 and p β = 0.046). Conclusions: The ANS appears to be sensitive in a frequency dependent manner to treatment with ELF-EMF. This is very important, if confirmed in further studies, not only for better understanding the mechanism of action of ELF-EMF on complex biological systems, but more impor tantly for therapeutic purposes under different levels of psy-chopathological discomfort like stress and anxiety, as well as for modulating perceived pain and organ dysregulation.
Superior outcomes in pediatric renal transplantation.

BACKGROUND Nationally, results of renal transplantation in children, particularly in small children, are inferior to those obtained in adults. OBJECTIVE To determine factors important for success in renal transplantation in children. DESIGN Results of 108 consecutive renal transplantations performed in patients aged 7 months to 18 years were reviewed and compared with those reported by the North American Pediatric Renal Transplant Cooperative Study (NAPRTCS), the national registry. RESULTS One-, 2-, and 3-year graft survival rates (+/-SE) were 99% +/- 1%, 95% +/- 3%, and 93% +/- 4%, respectively, for living donor grafts and 97% +/- 3%, 92% +/- 6%, and 92% +/- 6%, respectively, for cadaver grafts. Incidence of acute rejection was half that reported by NAPRTCS. There were no graft losses for technical reasons (19% in NAPRTCS). Twelve percent of patients were younger than 2 years (6% in NAPRTCS); 17% were 2 to 5 years old (16% in NAPRTCS). Most small children received an adult-sized kidney. Ninety-three percent of recipients weighing 15 kg or less received postoperative mechanical ventilation assistance to optimize fluid resuscitation and perfusion of adult-sized kidneys. Structural abnormalities of the urinary tract were present in 53.7% of the patients (48.5% in NAPRTCS; adults, 5.3%). Nephroureterectomy was required in 38 children; in 27 (71%) of them, it was performed at the time of transplant surgery. CONCLUSIONS Excellent results can be obtained in pediatric renal transplantation by strict adherence to surgical detail, tight immunosuppressive management, aggressive fluid management in the small child, and careful integration of urologic and transplant surgery.
Aerobic Bacterial Isolates and Their Antibiogram from Stool Samples of Infants and Young Children with Acute Gastroenteritis in Patients Attending a Tertiary Teaching Hospital in Central India

DOI: 10.21276/sjams.2019. 7.1. 2 Abstract: Introduction: There are multiple etiologies responsible for infectious gastroenteritis causing acute diarrhea which are often under diagnosed. Also acute diarrhea is one of the major causes of morbidity and mortality among children less than 5 years of age. Materials & Methods: The present study of bacteriology on aerobic bacteria causing diarrhea and their antibiogram from stool samples of infants and children less than 5 years of age was carried out in the Department of Microbiology, IIMSAR, and Indore from January 2018 to November 2018. Microscopic examination of stool sample was made by paring saline wet mount. Preliminary identification on culture media as required, biochemical tests and antibiotic sensitivity were done all the cases. Results: During the period of study the total numbers of 120 cases were included. In the present study the maximum number of cases of diarrhea occurred in 624 months of age group 83 (69.2%). Male child or boys had higher diarrhea cases 78 (65%) as compared to girls 42 (35%). Majority of the children 84 (70%) were breast fed combined with artificial feeds. Escherichia coli were found to be the predominant organism found in 42.5% of the cases. Salmonella was isolated from 7.5% of cases. Klebsiella 6.67% and Shigella 11.67% of the cases were isolated. Among Escherichia coli isolates majority of the strains were sensitive to chloramphenicol (94.12%) amikacin (92.16%) and gentamycin (84.31%). Conclusion: In the present study, E. coli was the commonest microorganism followed by Shigella. Thus, the importance of safe water and food hygiene would be most important intervention to prevent acute gastroenteritis in children.
E FFECTIVENESS OF DOMESTIC WASTEWATER TREATMENT IN THE “ G RMEČ ” TEACHING CENTER USING PILOT-SCALE CONSTRUCTED WETLAND AS UNCONVENTIONAL METHOD

Environmental care, higher requirements for quality of effluent, high cost of conventional wastewater treatment, and increased energy costs required for their work, have led scientists to more comprehensive research on a possibility of using a constructed wetland in wastewater treatment technology. Constructed wetlands are artificially shaped swamps with the aim of creating conditions conducive to the purification of wastewaters flowing through them. They are used for treatment of municipal wastewater from small settlements and a small industrial facility, as well as other types of wastewater. The educational pilot scale constructed wetland on which the research was conducted is located in the area of Bihać municipality, on a plot used by the Biotechnical Faculty in Bihać. The pilot scale constructed wetland for wastewater treatment covers an area of 20 m2 and is dimensioned for 10 equivalents of population. In this research we have examined the effectiveness of domestic wastewater treatment in the "Grmeč" Teaching Center using pilot scale constructed wetland. Plants planted in the constructed wetland were Typha latifolia and Phragmites australis, and the substrate was made of sand and pebbles of different granulations. The recipient of purified wastewater is the Drobnica stream, which is about 10 m away from the site. The research was conducted in May, with the flow varied depending on a weekly student workload. Efficiency of purification using constructed wetland depended on flow rate and organic wastewater load, ranging from 37.15% at a minimum flow of 9.89x10-6 m3/s and HPK values of 35 mgO2/L, up to 89.48% at the highest flow value of 2.51x10-5 m3/s, and HPK values of 189 mgO2/L. The highest concentration of ammonia in the influent was 145.62 mg N/L, and the lowest concentration of ammonia in the effluent was 6.31. mg N/L.
The Impact of Ownership Structure on Dividend Policy Evidence from Emerging Markets KSE-100 Index Pakistan

This study focus on one of important corporate decision that can have a great impact on the sentiments of the investor’s i.e. corporate dividend policy. This study investigates the determinants of the corporate dividend policy in the context of agency relation. The analysis of the study has based on the random sample of seventy firms from Karachi Stock Exchange KSE-100 index for the period of eight years ranging from 2003 to 2010. Stepwise multiple regression has used to investigate for the relationship of ownership variables with the dividend payouts. The empirical results suggested that there has a negative relationship between the dividend payouts and managerial share ownership and thus these are alternative tools that can be used to minimize the agency problem. Where there has positive relationship between the institutional and foreign share ownership suggested that the higher has their shareholdings the higher will be the firm dividend payouts that will leads to less availability of the cash flows with the opportunities managers to expropriate the shareholders wealth. Further more managerial share ownership has explanatory power of 18%. While the institutional ownership has explanatory power of 23.3% there for it can be concluded that the incremental effect of the institutional ownership in the model has about to 5% while that of the foreign ownership contribute about 1.9% with the total model explanatory power of 25.2%.

Possible Effect of 30 K Proteins in Embryonic Development of Silkworm Bombyx mori

The silkworm Bombyx mori possesses a 30K protein family of 3×104 Da, the biological functions of which have not been fully identified. The relationship between the 30K protein family and the embryonic development of temperature sensitive sex-linked mutant strain of silkworm was investigated by two dimensional polyacrylamide gel electrophoresis (2D-PAGE) and Matrix assisted laser desorption ionizationtime of flight mass spectrometry (MALDI-TOF MS). The results show that protein spots 1–5 of the 30K protein family, mainly existing in normal strain, are possibly related to embryonic development. The early consumption of a 30K protein named 6G1-30K-1 and the accumulation of 30K proteins named 6G1-30K-3 and 6G1-30K-4 are likely caused by the destruction of physiological balance in normal embryonic development, which may lead to lower hatchability of the temperature sensitive strain. The results suggest that reasonable metabolism of 30K proteins is a prerequisite for the embryo’s normal development.
Symptoms of PTSD in 124 survivors of the Holocaust.

OBJECTIVE Survivors of the Holocaust are expected to be at risk for posttraumatic stress disorder (PTSD), but few empirical data are available. This study investigated PTSD symptoms in Holocaust survivors with well-documented exposure to trauma. METHOD The German files of 124 Jewish Holocaust survivors who were judged to be free from bipolar affective disorder, obsessive-compulsive disorder, and organic brain syndrome were selected from those of 145 applicants to West German compensation boards. The psychiatric assessments were reexamined for explicit descriptions of current PTSD symptoms according to the DSM-III-R diagnostic criteria. A subgroup of 20 Auschwitz survivors with tattooed identification numbers were also compared with the 45 survivors who had not been in concentration camps. RESULTS Sixty-three percent of the total sample had been detained in concentration camps, and an average of 78% of their first-degree relatives were reported killed in the Holocaust. Forty-six percent of the total sample met the DSM-III-R criteria for PTSD. The most common symptoms were sleep disturbance, recurrent nightmares, and intense distress over reminders. The tattooed Auschwitz survivors had significantly more symptoms and were three times more likely to meet diagnostic criteria for PTSD than the survivors who had not been in concentration camps. CONCLUSIONS The results suggest a greater risk of chronic PTSD in survivors who were exposed to atrocities. Most survivors had not received adequate psychiatric care.
Response to : Assigning " frailty " SIR —

Sir—I read the paper by Perera et al. and the accompanying editorial with interest as there is a need for geriatricians to recognise the treatments and outcomes for frail adults. However, I have great difficulty in determining what cut score for the Edmonton Frail Scale (EFS) was used. It is not described in the article's Methods section. There are two relevant references. Wolfson et al. have measured the correlation of the EFS against a Geriatrician's Clinical Impression of Frailty questionnaire. Whilst they demonstrate a modest relationship (Pearson's r = 0.64), they do not identify a cut point in the EFS above, or below, which a classification of 'frailty' can reasonably be ruled in or out. Dasgupta et al. have found that EFS score ranges (≤3 or >7) have a reasonable relationship to the ability to predict which of an elderly cohort would not or would have post-operative surgical complications. But this is scarcely a reference against a 'gold-standard' for identifying frailty, and again the statistical power of the association is poor with receiver operator curve 'area under curve' data of 0.69 for all complications and 0.65 for cardiac complications. So, while there is an association for the EFS with other measures of frailty, I cannot apply these data to any other population of elderly because the key defining criterion is not given.
A route for reliable conductive scanning probe characterization of FIB machined ZnO nanopillars

Zinc oxide structures with size in the micro and nano-scale range represent key candidates for developing novel, cheap and efficient electronic devices, power generators and sensors based on the cooperative response of a large number of synced structures. The accurate electrical characterization of single ZnO micro/nanostructures is thus critical for assessing and optimizing the device performance and reliability, and requires the use of metallic scanning nano-probes for establishing electrical contact with the nano-structures. We report on the characterization of the contact resistance between AFM conductive tip and a selection of metallic layers to be used as top metallic coating allowing for nano-electrical characterization of FIB machined ZnO micro/nanopillars. Our findings show that the use of an Au film on top of Ti ohmic contact layer is crucial for reliable conductive AFM investigation of single isolated ZnO micro and nano-structures.
THE IMPACT OF SOCIAL CAPITAL ON MARKET EXPLORATION AND EXPLOITATION WITH MEDIATING ROLE OF INTERNAL COMMUNICATION

Purpose – Present study aims to test the mediating role of internal communication on the relationship between social capital and market exploration and exploitation, and to link the impact of market exploration and exploitation to the firm performance. Methodology - The hypotheses derived from the literature were tested on a sample of 173 information technology firms in Turkey. Survey data was gathered through questionnaires which were applied to the managers of the firms. Relationships among variables were analyzed through structural equation modeling using Amos 25.0 statistical tool. Findings- Internal communication's full mediating impact on the relationship between social capital and market exploitation and exploration was supported. In return, market exploration was found to have a significant impact on firm performance which was measured by quality, innovation, reputation and customer satisfaction. Conclusion- Social capital is an antecedent for an effective internal communication and should be well established in the firms. Internal communication has an impact on both market exploration and exploitation activities, thus it should be supported and encouraged within the firms. Market exploration activities should not be neglected since they may contribute to firms’ performance especially in the long run.

Machine Learning and the Stock Market

Abstract Practitioners allocate substantial resources to technical analysis whereas academic theories of market efficiency rule out technical trading profitability. We study this long-standing puzzle by applying a diverse set of machine learning algorithms. The results show that an investor can find profitable technical trading rules using past prices, and that this out-of-sample profitability decreases through time, showing that markets have become more efficient over time. In addition, we find that the evolutionary genetic algorithm’s attitude in not shying away from erroneous predictions gives it an edge in building profitable strategies compared to the strict loss-minimization-focused machine learning algorithms.
Glomerular endothelial cell differentiation.

BACKGROUND Glomerular endothelial cells differ from most other endothelial cells in that they are extraordinarily flattened and highly fenestrated. In this differentiated form, they allow formation of glomerular ultrafiltrate at a prodigious rate. METHODS Molecular processes that dictate the development and differentiation of glomerular endothelium are reviewed. RESULTS During glomerular development, angioblasts already present in the metanephric blastema well before any organized angiogenic sprouts invade the capillary cleft of developing nephrons at the comma and S-shape stages in response to chemotactic and guiding cues from primitive podocytes. The angioblasts then undergo homotypic aggregation into precapillary cords as yet devoid of a lumen. Lumen development then proceeds through the loss of superfluous endothelial cells by apoptosis as well as flattening of the remaining viable endothelial cells. The final step, fenestration, is critically dependent on appropriate stimuli, most notably vascular endothelial growth factor A (VEGF-A), from differentiated podocytes. Current evidence suggests that the fenestrae of fully differentiated glomerular endothelium can be lost within hours if the VEGF-A stimulus is removed, and that the glomerular endotheliosis, loss of glomerular filtration rate (GFR) and proteinuria observed in preeclampsia are due to the circulating inhibitor of VEGF-A, soluble VEGF receptor 1 (VEGFR-1). CONCLUSION Differentiation of the glomerular endothelium is highly dependent on podocyte-derived stimuli and their loss leads to the derangements of glomerular function in preeclampsia.
Proteases and metastasis: clinical relevance nowadays?

Purpose of review A great deal of breast cancer research has been devoted to the search for new prognostic and predictive markers which could, on the one hand, enable a more precise identification of patients at high risk of recurrence and, on the other hand, predict the response of each individual patient to the administered therapy. Proteases have been the center of interest because of their prominent involvement in cancer progression and metastasis. In particular, the matrix metalloproteinases, the serine protease urokinase plasminogen activator, the cathepsins, and corresponding inhibitors have been studied extensively. This article reviews the developments during the last year in this field. Recent findings The prognostic effect of urokinase plasminogen activator and plasminogen activator inhibitor 1 was confirmed in a meta-analysis and in a prospective randomized clinical study that provided level 1 evidence for the clinical value of these markers. Furthermore, encouraging data suggest that both urokinase plasminogen activator and plasminogen activator inhibitor 1 might be important predictive markers. To date, findings on the prognostic and predictive value of the matrix metalloproteinases, the cathepsins, and their inhibitors are still inconclusive. Summary On the basis of currently available data, tumor urokinase plasminogen activator and plasminogen activator inhibitor 1 levels could already be used in everyday clinical practice for selection of candidates for adjuvant systemic therapy. Further effort should be put into the standardization of the matrix metalloproteinases and cathepsins determination so that their clinical relevance in breast cancer can be defined.
A Meta-Analysis of Icodextrin versus Glucose Containing Peritoneal Dialysis in Metabolic Management of Peritoneal Dialysis Patients

Objectives: The objective of this article is to study the available works on comparison between icodextrin-based solutions (ICO) and glucose-based solutions (GLU) in peritoneal dialysis (PD) patients. The final aim was to get evidence for potential differences in metabolic management of PD patients by comparing the ICO with the GLU for the long dwell once a day. Methods: A meta-analysis of included reports, identified by MEDLINE and other sources, containing information on fasting plasma glucose, total cholesterol, triglycerides, and so on in PD patients, was performed. Results: Nine randomized controlled trials (RCTs) (553 patients) were included. The ICO did not differ from the GLU with respect to fasting plasma glucose (weighted mean difference (WMD) = −0.76; 95% confidence interval (CI) = −1.79 to 0.28; Z = 1.43; p = 0.15), triglycerides (WMD = −0.66; 95% CI = −1.40 to 0.09; Z = 1.73; p = 0.08), and body weight (WMD = −2.02; 95% CI = −5.06 to 1.03; Z = 1.30; p = 0.20). But peritoneal creatinine clearance (WMD = 0.49; 95% CI = 0.34–0.64; Z = 6.35; p < 0.00001), urea clearance (WMD = 0.40; 95% CI = 0.25–0.55; Z = 5.12; p < 0.00001), and plasma total cholesterol (WMD = −0.40; 95% CI = −0.70 to −0.10; Z = 2.64; p = 0.008) were higher for the ICO versus the GLU. Conclusions: The ICO had been shown to have significant advantages over the GLU in small solute clearance and plasma total cholesterol. Patients, no matter what kind of PD solution was used, had no significant difference of plasma triglycerides, fasting plasma glucose, and body weight.
Combined Power Control and Partially Overlapping Channel Assignment for Interference Mitigation in Dense WLAN

Multiple overlapping transmissions cause a serious performance degradation in dense wireless local area network (WLAN) due to increased level of interferences. The issue of interference management becomes extremely challenging particularly for IEEE 802.11 b and g standards where the number of non-overlapping channels (NOCs) is only 3. Power control at the access points (APs) plays a major role to interference management as it determines the transmission radii of the APs. But inappropriate determination of transmission power may put several users out of the coverage range. Efficient use of partially overlapping channels (POC) may lead to increased frequency reuse as it reduces the interference range. But excessive use of POCs may cause reduced quality of service (QoS) due to increased adjacent channel interferences. In this paper we propose an effective power control and POC assignment algorithm that jointly considers power tuning and POC assignment along with NOC to maximize the network performance. Through extensive simulation the performance of the algorithm is evaluated to establish the importance of considering these two factors jointly. Furthermore it has been shown that the proposed approach outperforms some existing approaches.
