    Full Text Available The aim of this study was to introduce a new morphometric index named Relief Index (RI. RI is the ratio of the total length of the contour lines and the surface area at which they occur. This easily calculated index provides an objective quantitative measure of relief variability as an important feature in geomorphological studies. To achieve this goal, a highly detailed morphometric analysis was carried out using a high-resolution (1m×1m DEM. Twenty one sample areas in southern Poland were examined. These analyses showed RI, as a good tool for rapidly evaluating topography heterogeneity in division into relief classes. I distinguished 4 classes of the Relief Index that classify earth surface considering the variability of the relief. Results of the calculations demonstrated that there is a significant correlation between RI and the local relief and slopes, but there is no correlation between RI and planar curvatures and TWI. The relief of the sample areas were analysed using geomorphometric parameters (slopes, local relief, planar curvatures. Moreover the influence of the DEM resolution on Relief Index values was examined.

    The aim of this study was to evaluate Doppler renal resistance index (RI) and RI ratio (RIR) in differentiating between obstructive and nonobstructive hydronephrosis in children and adolescents. The RI and RIR were measured in 32 healthy examinees (control group) and 29 patients with unilateral hydronephrosis. Ten patients had acute obstruction caused by a ureteric stone. Seven had obstructive hydronephrosis due to uretero-pelvic junction (UPJ) obstruction. Twelve patients had nonobstructive hydronephrosis. In controls the mean RI±S.D. was 0.615±0.04, and RIR 1.045±0.033. In children with acute obstruction RI was 0.692±0.035 and RIR 1.148±0.037. In UPJ obstruction RI was 0.631±0.054 and RIR 1.059±0.047. In nonobstructive dilatation RI was 0.61±0.038 and RIR 1.043±0.042. The RI and RIR differences were statistically significant between controls and patients with acute colic (p<0.01), and between patients with acute obstruction and with nonobstructive hydronephrosis (p<0.01). In detecting acute obstruction RI≥0.70 was found to have a 70% sensitivity and a 92% specificity. The RIR≥1.10 was found optimal to distinguish obstructive from nonobstructive dilatation (sensitivity 90%, specificity 83%). Both RI and RIR are significantly elevated in patients with acute obstruction. Renal Doppler seems to be useful in children and adolescents for the detection of acute renal obstruction, although it cannot differentiate chronic obstruction due to the UPJ obstruction and nonobstructive renal collecting system dilatation.

    This study was aimed to review findings of gray-scale ultrasonography and to assess the diagnostic value of the resistive index (RI) in patients with acute epididymitis by comparing with that in normal volunteers. Gray-scale ultrasonogram was reviewed in nine patients with acute epididymitis for echogenicity, size and reactive hydrocele. Normal values of resistive index (RI) were obtained in 20 epididymides from 10 volunteers (aged 20-28, mean 23.7). Nine patients of epididymitis (aged 18-67, mean 37.2) were examinated with color Doppler sonography and RI was measured at 11 sites on epididymal arteries. For the prediction of acute epididymitis, accuracy, sensitivity and specificity were calculated at the cut-off value of RI in 0.65 and 0.70. Gray-scale ultrasonography showed echogenicity that was variable among the 9 cases (hyperechoic 2 cases, isoechoic 2, hypoechoic 5), enlargement of epididymis in 8, and reactive hydrocele in 8 cases. Normal volunteers displayed color Doppler signals in 14 out of 20. The range of RI in normal volunteers were between 0.64 and 1.00 (mean, 0.79 ± SD 0.10). In patients with acute epididymitis, color Doppler signals were detected in all patients. The range of RI in epididymitis were 0.40-0.68 (mean, 0.56 ± SD 0.10). At cut-off RI value of 0.65, accuracy was 88%, sensitivity 81.1%, and specificity 92.7%. At cut-off value of 0.70 accuracy was 92%, sensitivity 100%, and specificity 85.7%. In addition to the findings of gray-scale ultrasonography, resistive index and color flow changes are valuable in diagnosing acute epididymitis

    The objectives were to determine the resistive index (RI) in normal cats and in cats with various renal diseases, and to evaluate the effect of age on RI. The subjects were cats that had ultrasonography (US) of the urinary tract and RI measurement at our centre between January 2003 and April 2014. Based on clinical evaluation, biochemical and haematological tests, urinalysis and US, the cats were classified as healthy or diseased. RI measurements were made from the interlobar or arcuate arteries. Data were analysed for differences between the right and the left kidney, the two sexes, different age groups in healthy cats, and between healthy and diseased cats. A total of 116 cats (68 males, 48 females) were included: 24 healthy and 92 diseased. In the healthy cats, RI (mean ± SD) differed significantly (P = 0.02) between the right kidney (0.54 ± 0.07) and the left kidney (0.59 ± 0.08). For the left kidney, RI was significantly higher in cats with chronic kidney disease (0.73 ± 0.12) and acute kidney injury (0.72 ± 0.08) (P = 0.0008). For the right kidney, RI was significantly higher in cats with chronic kidney disease (0.72 ± 0.11), acute kidney injury (0.74 ± 0.08), polycystic kidney disease (0.77 ± 0.11) and renal tumour (0.74 ± 0.001) (P cats, useful in the differential diagnosis of diffuse renal diseases. While it does not change with the age of the cat, ultrasonographers should be aware that RI may differ between the two kidneys. © ISFM and AAFP 2015.

    We evaluated the relationship between prostatic resistive index (RI) and cardiovascular system (CVS) risk factors in patients with benign prostatic hyperplasia. The study included 120 patients who were attending our outpatient clinic with lower urinary tract symptoms related to benign prostatic hyperplasia. The clinical, laboratory, anthropometric data, and CVS risk factors (hypertension, diabetes mellitus, metabolic syndrome, history of CVS events, and smoking) of the patients were evaluated regarding the association between prostate RI level by regression analyses. The prostatic RI levels of the patients were measured using power Doppler imaging. In univariate regression analysis, there were statistically significant relationships between prostatic RI levels and the patients' age, International Prostate Symptom Score, hip circumference, fasting blood glucose, prostate specific antigen, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total prostate volume, uroflowmetric maximal flow rate, and all investigated CVS risk factors (p prostatic RI levels were found to be associated with fasting blood glucose and total prostate volume, and also with CVS risk factors including only metabolic syndrome and cigarette smoking in the multivariate regression analysis. Our results showed that prostatic RI level is significantly related to metabolic syndrome and smoking among the investigated CVS risk factors. Copyright © 2015. Published by Elsevier Taiwan.

    To determine whether the value of the intrarenal resistive index(RI) can be used to identify early kidney vasoconstriciton in patients with nonazotemic liver cirrhosis The intrarneal resistive index (RI), kidney and liver function and plasma renin activity were measured in 12 healthy control subjects, 13 cirrhotic patients without ascites and 29 cirrhotic patients with ascites. To evaluate the development of hepatorenal syndrome, patients were followed up for six months. RI was significantly higher in patients with cirrhosis (0.68{+-}0.06) than in healthy subjects (0.59{+-}0.04). In 42 cirrhotic patients, it was significantly higher in those with ascites (0.69{+-}0.05) than in those without ascites (0.64{+-}0.05) and correlated with creatinine clearance. Plasma renin activity was significantly highter in cirrhotic patients with ascites than in those without ascites and healthy subjects (p<0.05). During the six-month follow-up period, kidney dysfunction developed in 16%(7/42) of cirrhotic patiens, and in 37%(6/16) of those with an elevated RI. In contrast, only 4%(1/26) of patients with a normal RI has kidney dysfunction. The measurement of intrarenal resitive index(RI) using duplex Doppler ultrasound is a simple, noninvasive method of detecting even subtle derangements of renal hemodynamics in liver cirrhosis patients;the procedure can be used to identify those who are at higher risk of overt renal failure and to help decide whether a therapeutic approach involving paracentesis, diuretics, or nephrotoxic agents is most appropriate.

    Postoperative acute kidney injury (AKI) is linked to an increase in morbidity and mortality, particularly in elderly populations. This study's aim was to assess the accuracy of the Doppler renal resistive index (RI) in detecting AKI at an early stage after hip fracture surgery. This prospective single-centre study included 48 patients suffering hip fractures requiring surgery and who presented risk factors for the development of AKI. The RI was calculated preoperatively and postoperatively in patients without pain and with haemodynamic and respiratory stability. The occurrence of AKI was determined by measurements of serum creatinine according to AKIN criteria. Twenty-nine patients (60%) developed AKI during the first five postoperative days, without need for dialysis. The RI was increased in patients who developed postoperative AKI 0.68 (0.67-0.71) vs. 0.72 (0.7-0.73); P=0.014 for the preoperative index; and 0.6 (0.58-0.68) vs. 0.74 (0.71-0.76); Pcalculation of the RI during the perioperative periods of hip fracture surgery predicts early and effectively the postoperative occurrence of AKI, thus allowing treatment to be anticipated so as to improve patient prognosis.

    Renal ischemia and direct toxic effect of contrast media are the main confounding causes of contrast-induced nephropathy (CIN). The effect of different contrast mediums on the resistance of renal artery is quite unclear. The aim of the present study was to assess the resistive index (RI) changes of renal segmental artery in color Doppler duplex sonography after injection of two different contrast mediums: iodixanol and iohexol. The RI of the renal segmental artery of 62 randomly chosen patients, with a normal baseline renal function, was calculated using color-coded Doppler sonography before and five minutes after bolus injection of two different contrast mediums. Thirty-one patients were administered 50 mL of iodixanol (Visipaque) and 31 patients were administered 50 mL of iohexol (Omnipaque) during intravenous urogram procedures. The RI results were analyzed and compared in two groups using two-tailed t-test. The mean RI of renal segmental artery increased significantly after administration of contrast media (mean + - SD 0.61 + - 0.046 vs 0.58 +- 0.042; p< 0.001). The mean change of RI was 0.0387 +- .00552 (mean + - SE) in the setting of iohexol injection and 0.0216 + - .00423 (mean + - SE) five minutes after administration of iodixanol (p0.017). Both non-ionic iso-osmolar dimeric iodixanol and low-osmolar iohexol increase the renal artery resistance, but the changes are more dramatic with iohexol, suggesting better tolerance with iodixanol.

    From growing data from the literature emerges that so-called ecoDoppler "Renal" Resistive Indexes (RRI) are not only specific markers of kidney damage and indicators of renal functional prognosis but they always express more clearly a strong link with the systemic circulation. In fact, some cardiovascular parameters such as aortic pulse pressure, aortic stiffness, abdominal aortic calcifications and clinical settings for instance heart failure progression have shown a great association with RRI. Relationships between renal and inflammatory indexes in hypertensive patients have been found and data from the literature on kidney transplants underline the capability of the graft RRI to change according to host hemodynamic features. The purpose of this article is to explain the emerging pathophysiological aspects of this relationship between renal microcirculation and cardiovascular system by emphasizing the importance for the ultrasonographer and for the nephrologist of not overlooking a global vision of the patient before interpreting the RRI.

    Prostate cancer (PCa) remains the second leading cause of cancer diagnosis worldwide. Early diagnosis and treatment of PCa is critical since the long-term prognosis is excellent in patients with tumors confined to the prostate gland. The current meta-analysis investigates the diagnostic value of resistive index (RI) measurement using color Doppler ultrasound in patients with PCa. Electronic literature databases were exhaustively searched for relevant studies published prior to May 31, 2014. Nine studies met our predetermined inclusion criteria for the present meta-analysis. The methodologic quality of the selected studies was independently assessed by 2 reviewers based on Quality Assessment of Diagnostic Accuracy Studies tool. Our meta-analysis results showed that RI values were significantly higher in malignant prostate tissues compared to normal prostate tissues (standardized mean difference [SMD] 0.42, 95% confidence interval [CI] 0.12~0.73, p = 0.007) and benign prostate tissues (SMD 0.41, 95% CI 0.26~0.56, pbased on the diagnostic instruments used revealed that RI values were accurate in diagnosis of PCa when compared between malignant tissue vs normal tissue and malignant tissue vs benign tissue (all pvalues in diagnosis of PCa.

    Environmental safety in multi-district boundary regions has been one of the focuses in China and is mentioned many times in the Environmental Protection Act of 2014. Five types were categorized concerning the risk sources for surface water pollution in the multi-provincial boundary region of the Taihu basin: production enterprises, waste disposal sites, chemical storage sites, agricultural non-point sources and waterway transportations. Considering the hazard of risk sources, the purification property of environmental medium and the vulnerability of risk receptors, 52 specific attributes on the risk levels of each type of risk source were screened out. Continuous piecewise linear function model, expert consultation method and fuzzy integral model were used to calculate the integrated risk indexes (RI) to characterize the risk levels of pollution sources. In the studied area, 2716 pollution sources were characterized by RI values. There were 56 high-risk sources screened out as major risk sources, accounting for about 2% of the total. The numbers of sources with high-moderate, moderate, moderate-low and low pollution risk were 376, 1059, 101 and 1124, respectively, accounting for 14%, 38%, 5% and 41% of the total. The procedure proposed could be included in the integrated risk management systems of the multi-district boundary region of the Taihu basin. It could help decision makers to identify major risk sources in the risk prevention and reduction of surface water pollution.

    ABSTRACT

    Karst voids were encountered during road construction in Yongweol-ri, South Korea. Attempts to determine the extent of the karst voids through drilling was expensive, time-consuming and too dangerous. An electrical resistivity survey was thus carried out to investigate current subsurface geology beneath the proposed road network. This investigation was aimed at imaging karstic voids and detecting areas prone to ground subsidence through the collapse of cavities beneath a road segment overlying such features. A numerical modelling study preceded the field survey to determine whether the electrical resistivity method could identify such features. The field data set consisted of eleven electric profiles acquired using dipoledipole array; electrical resistivity profiles (100 m and 300 m length were measured using a dipole-dipole electrode configuration and electrode spacing was kept at 5 m to ensure good coverage of the study area. The resistivity data was inverted using 2D and 3D algorithms based on the least squares smoothness constraint technique. The inverted resistivity images provide a clear view of weathered soils, the distribution of weak areas or karst voids and bed rock. Several low resistivity areas were identified and the subsequent drilling of such anomalous areas led to the discovery of several weak zones or clayfilled underground cavities; the drilling results had excellent correlation with the resistivity images. The electrical resistivity imaging result proved precise and extremely efficient in delineating the karstic void investigation and should be taken into account when choosing an investigation technique to be used at complex geological sites. A remedial action plan involving consolidation grouting work has been suggested prior to road construction.

    To develop reference cutoff values for mean fetal lung volume (FLV) and pulmonary artery resistance index (PA-RI) for prediction of neonatal respiratory distress syndrome (RDS) in low-risk term pregnancies. As part of a cross-sectional study, women aged 20-35 years were enrolled and admitted to a tertiary hospital in Cairo, Egypt, for elective repeat cesarean at 37-40 weeks of pregnancy between January 1, 2012, and July 31, 2013. FLV was calculated by virtual organ computer-aided analysis, and PA-RI was measured by Doppler ultrasonography before delivery. A total of 80 women were enrolled. Neonatal RDS developed in 11 (13.8%) of the 80 newborns. Compared with neonates with RDS, healthy neonates had significantly higher FLVs (P<0.001) and lower PA-RIs (P<0.001). Neonatal RDS is less likely with FLV of at least 32 cm(3) or PA-RI less than or equal to 0.74. Combining these two measures improved the accuracy of prediction. The use of either FLV or PA-RI predicted neonatal RDS. The predictive value increased when these two measures were combined. Copyright © 2014 International Federation of Gynecology and Obstetrics.

    To evaluate the usefulness of renal resistive index(RI) in patients with liver cirrhosis as an indicator for predicting hepatorenal syndrome. Renal RIs of thirty cirrhotic patients were analyzed using the gray-scale and Doppler ultrasonograms. As a control group, eight normal subjects were included. Renal RIs were measured at three sites of interlobar or arcuate arteries of both kidneys. The patients were divided into three groups (A, B, or C) according to the Child-Turcotte-Pugh classification and their serum BUN and creatinine levels were compared. We determined whether RIs of normal controls differed from those of cirrhotic patients or whether RIs of cirrhotic patients correlated with the Child-Turcotte-Pugh classification or BUN and creatinine levels. Mean RIs(0.63 {+-}0.33) of normal subjects were statistically different from those(0.67 {+-} 0.05) of cirrhotic patients(P=0.009). RIs of group A(n=6), B(n=9) and C(n=15) were 0.65 {+-} 0.03, 0.65 {+-} 0.04 and 0.70 {+-} 0.04, respectively. The ANOVA test revealed statistically significant differences between the three groups(F ratio=4.472, P=0.021). RIs did not correlate with BUN or creatinine levels. RI could be used as an index for predicting hepatorenal syndrome before the renal function becomes impaired.

Materials and Methods In this retrospective study, Doppler waveforms were obtained from intramural appendiceal arteries identified with color Doppler imaging in 60% (93 of 155) of consecutive patients whose appendices were visualized at graded compression ultrasonography (US) performed for suspected appendicitis (53 male and 40 female; age, 1-56 years; mean, 14.5 years) over the 5-month period from November 2015 through March 2016. Point, non-angle-corrected peak systolic velocity (PSV) and resistive index (RI) values were compared between patients with and patients without appendicitis by utilizing histopathologically proven appendicitis and 6-week clinical follow-up as diagnostic reference standards. Data were assessed by using the Student t test, exact binomial distribution, two-sample test of proportions, and receiver operating characteristic analysis. Results Among the 93 patients, 36 (38.7%) had proven appendicitis (mean PSV, 19.7 cm/sec; mean RI, 0.69) and 57 patients (61.2%) did not (mean PSV, 7.1 cm/sec, P appendicitis was 0.97 (95% confidence interval [CI]: 0.95, 1.00) for PSV and 0.86 (95% CI: 0.78, 0.95; P = .011) for RI. Chosen discriminatory criteria of PSV greater than 10 cm/sec and RI greater than 0.65 yielded specificity for appendicitis of 94.7% and 96.5% with sensitivity of 88.9% and 63.9% (P = .013) and negative predictive value of 93.1% and 80.9% (P = .045), respectively. Original clinical graded compression US interpretations based on established US findings demonstrated specificity of 96.2% and sensitivity of 100.0%. Considering the subset of 20 patients whose maximum outer diameter measured 6-8 mm, the discriminatory criteria of PSV greater than 10 cm/sec and RI greater than 0.65 yielded specificity for appendicitis of 88.9% each, with sensitivity of 100.0% and 63.6% and negative predictive value of 100

    This study focused on the molecular characterization of a small cryptic, mobilizable plasmid (6038 bp) sequenced from an E. faecium 9631160-1 of poultry origin. Sequence analysis of pRI1 revealed seven open reading frames. pRI1 contained an IS 100% identical to ISEfa4. This insertion element...... almost identical to the repA from the pEFNP1 and pKQ10 plasmids from E. faecium was also identified. Presence of the pRI1 replication initiation gene (rep) was analyzed in a panel of 159 E. faecium isolates of human and animal origin from different European countries, of which 60 tested positive...... for the presence of pRI1-rep. Conjugation experiments verified transfer of the pRI1 together with conjugative plasmids harboring resistance to vancomycin and streptogramin. The presence of pRI1 in enterococcal isolates geographically separated and from different origin demonstrates the ability of enterococci...

    Insulin resistance assessment requires sophisticated methodology of difficult application. Therefore, different estimators for this condition have been suggested. The aim of this study was to evaluate the triglycerides and glucose (TyG) index as a marker of insulin resistance and to compare it to the triglycerides/HDL cholesterol ratio (TG/HDL-C), in subjects with and without metabolic syndrome (MS). An observational, cross-sectional study was conducted on 525 adults of a population from Bahia Blanca, Argentina, who were divided into two groups: with MS (n=89) and without MS (n=436). The discriminating capacities for MS of the TyG index, calculated as Ln (TG [mg/dL] x glucose [mg/dL]/2), and the TG/HDL-C ratio were evaluated. Pre-test probability for MS was 30%. The mean value of the TyG index was higher in the group with MS as compared to the group without MS and its correlation with the TG/HDL-C ratio was good. The cut-off values for MS in the overall population were 8.8 for the TyG index (sensitivity=79%, specificity=86%), and 2.4 for the TG/HDL-C ratio (sensitivity=88%, specificity=72%). The positive likelihood ratios and post-test probabilities for these parameters were 5.8 vs 3.1 and 72% vs 58% respectively. The cut-off point for the TyG index was 8.8 in men and 8.7 in women; the respective values for TG/C-HDL were 3.1 in men and 2.2 in women. The TyG index was a good discriminant of MS. Its simple calculation warrants its further study as an alternative marker of insulin resistance. Copyright © 2014 SEEN. Published by Elsevier Espana. All rights reserved.

    Full Text Available Erythropoietin resistance index calculation has been used as a tool to evaluate anemia response to erythropoietin therapy. Very little has been reported in its use when using darbepoetin and factors influencing in Arab patients. Darbepoetin resistance index (DRI was calculated in all our patients using darbepoetin. This was correlated to demographic, clinical, and laboratory parameters. Of the 250 patients, 40.4% were diabetic, 71.1% on hemodialysis, and 28.6% on hemodiafiltration, 23.9% with PermCaths (PC, and 76.1 % with arteriovenous fistula (AVF. The mean DRI was 10.96 ± 12.9 I. Females had 45% higher DRI than males (P = 0.005, and patients with PC had a 66% higher DRI than those with AVF (P = 0.029. Patients with Vitamin D level below the 50th percentile had 55.9% higher DRI than those above it (P = 0.05. DRI was negatively correlated with age (P = 0.018, dialysis vintage (P = 0.039, interdialytic weight gain P = 0.007, Vitamin D level, and serum albumin (P = 0.005 and positively correlate with parathyroid hormone (PTH level (P = 0.000. No impact was seen by the mode of dialysis, being diabetic, using anti-hypertensive therapy, body mass index, Kt/V, serum iron, total iron binding capacity, transferrin saturation, ferritin, C-reactive protein, Ca, or P. DRI in our Arab patients was comparable to erythropoietin resistance indices reported in other communities. Higher DRI was observed in females, PC users, lower serum albumin, lower Vitamin D, and shorter dialysis vintage. A negative correlation existed between DRI and age, dialysis vintage, interdialytic weight, and serum albumin and a positive correlation with PTH level.

    Primary hyperparathyroidism (PHPT) has been considered a cause of insulin resistance (IR) and impaired glucose metabolism. However, there are conflicting results related with the recovery of insulin resistance in patients with PHPT following curative parathyroidectomy. Our aim is to evaluate the effects of curative parathyroidectomy on IR in patients with PHPT. This is a prospective interventional study. Twenty-one consecutive patients with symptomatic PHPT were included into the study. All patients underwent parathyroidectomy. Fasting serum glucose, calcium, phosphorous, parathormone, plasma insulin, and vitamin D levels were measured both at baseline and 2 months after parathyroidectomy. Insulin resistance was calculated by homeostasis of model assessment-insulin resistance (HOMA-IR). Two months after curative parathyroidectomy, serum levels of calcium ( p  = 0.001), PTH ( p  HOMA-IR ( p  = 0.003) decreased, while phosphorous levels increased ( p  = 0.001). During this period, no changes were observed at vitamin D and glucose levels. We concluded that curative parathyroidectomy decreases HOMA-IR index in patients with PHPT. Studies with larger population and longer follow-up period are required to confirm our results.

    The relationship between nutrition and atherosclerosis is known, even dissociated from protein malnutrition. Cardiovascular impact of several nutrients is known; among them the action of coffee is still debated and cardiovascular effect of caffeine has been investigated without definite results. The aim of this study is to investigate whether coffee habits, and/or quantity of coffee consumption, have any relationship with renal resistive index (RRI), a hallmark of arterial stiffness (AS). The relationship of AS with nutritional status assessed by body composition and serum albumin, insulin resistance (assessed by HOMA), and renal function assessed by glomerular filtration rate (GFR) is concurrently investigated. This study was done with 221 consecutive patients, without diabetes, cancer, liver, renal, and heart disease, referred for clinical noninvasive assessment and nutritional counseling: 124 essential hypertensive and 97 nonhypertensive patients were eligible. Personalized Mediterranean diet, physical activity increase, and smoking withdrawal counseling were provided. By multiple linear regression, fat-free mass (FFM), HOMA (positive relationship), and number of cups of coffee/day (negative relationship) account for 17.2% of the variance to RRI. By odds ratios lower risk to increased RRI is associated with higher serum albumin, higher hemoglobin, and FFM; greater risk is associated with hypertension, insulin resistance (HOMA ≥ 3.0), and renal insufficiency (GFR ≤ 90); coffee, assessed by number of cups/day, reduces risk. Coffee use is inversely associated with RRI. Habitual coffee users have risk protection to higher RRI; lower serum albumin, insulin resistance, and renal insufficiency are associated with greater RRI.

    Purpose: the goal of this study was to evaluate effects of extracorporeal shock wave lithotripsy (ESWL) on the renal perfusion using the resistive index (RI), perfusion scintigraphy, magnetic resonance (MR) perfusion imaging and plasma big-endothelin (big-ET-1) values. Method/materials: In 21 patients divided in 3 age-groups the RI was measured before and 1,3,6 and 24 hours after ESWL. Big-ET-1, a potent vasoconstrictor peptid was correlated with the RI values. The RI and Big-ET-1 results was compared to the results of the MR perfusion imaging and the scintigraphy, the gold-standard method. Results: The RI of the treated kidneys increased significantly from 0,64±0,05 to 0,72±0,08 after the ESWL (p<0,001) and in the untreated kidneys from 0,63±0,05 to 0,68±0,09 (p=0,003). The hightest age group shows the most significant increase. The Big-ET-values also increased only in this age group significantly from 0,78±0,24 fmol/l to 1,58±0,52 fmol/l. In the scintigraphy the decrease of the renal plasma flow (RPF) in this age group was most significant. The MR perfusion Imaging shows in all age groups significant decrease (p<0,001). Conclusion: we conclude that the ESWL causes considerable renal parenchymal damage only in the elderly patients. The following changes in renal perfusion were measured very sensitively with the RI which had a good correlation to the results of the perfusion scintigraphy and the MR perfusion imaging. Further studies with larger series have to evaluate these results. (author)

    The aim of our study was to identify variables of prognostic relevance for disability pensions (DP) in the register data of the German Pension Fund (GPF) and to use the identified variables to construct a risk index. The study was designed as a case-control study of insurants of the GPF Bund using disability pensioners from 2004-2008 as cases and active insurants as controls. Independent variables were selected from the accumulated register data from 2001-2003. Data of 8,500 men and 8,405 women were analyzed. The strongest predictor of future DP were days of sickness benefits. Men with short-term benefits had 6.1 times higher odds of receiving a DP, while men receiving long-term benefits had even 66.3 times higher odds of receiving a DP. For women, the odds were increased 3.8 and 38.4 times, respectively. The risk index score was calculated by transforming the linear combination of parameter estimators and personal characteristics to values ranging from 0-100. ROC analyses and survival analyses confirmed the prognostic relevance of the index score. Independent samples were used to validate our models. Our results show that the GPF has information which could enable an active strategy to enhance the provision of medical rehabilitation.

    Renal resistive index (RRI) measured by Doppler ultrasonography is associated with cardiovascular events and mortality in hypertensive, diabetic, and elderly patients. We studied the factors associated with high RRI (≥0.70) and its associations with mortality in chronic kidney disease patients without renal artery stenosis. We included 1962 patients with an estimated glomerular filtration rate of 15 to 59 mL/min per 1.73 m(2) who also had RRI measured (January 1, 2005, to October 2011) from an existing chronic kidney disease registry. Participants with renal artery stenosis (60%-99% or renal artery occlusion) were excluded. Multivariable logistic regression model was used to study factors associated with high RRI (≥0.70), and its association with mortality was studied using Kaplan-Meier plots and Cox proportional hazards model. Hypertension was prevalent in >90% of the patients. In the multivariable logistic regression, older age, female sex, diabetes mellitus, coronary artery disease, peripheral vascular disease, higher systolic blood pressure, and the use of β blockers were associated with higher odds of having RRI≥0.70. During a median follow-up of 2.2 years, 428 patients died. After adjusting for covariates, RRI≥0.70 was associated with increased mortality (adjusted hazard ratio, 1.29; 95% confidence interval, 1.02-1.65; Pchronic kidney disease. Noncardiovascular/non-malignancy-related deaths were higher in those with RRI≥0.70. RRI≥0.70 is associated with higher mortality in hypertensive chronic kidney disease patients without clinically significant renal artery stenosis after accounting for other significant risk factors. Its evaluation may allow early identification of those who are at risk thereby potentially preventing or delaying adverse outcomes. © 2015 American Heart Association, Inc.

    Full Text Available Abstract Background: Adipose tissue's phenotypic alteration due to exercise training is a new theory. However, the cellular–molecular mechanisms for these phenotypic alterations are not yet clearly understood. The aim of this study was to investigate the effects of six weeks resistance training on Meteorin-like hormone level and insulin resistance index in overweight adolescent boys. Materials and Methods: Twenty overweight adolescent boys (average age 18.5±1 years old, average weight 81.1±4.5 kg, and BMI 27.7±0.7 kg/m2 participated in this study. The subjects were randomly assigned into two groups: control (N=10 and resistance training (N=10. Subjects in training group performed six-week resistance training program 3 days/week. Anthropometrics parameters and fasting serum of Meteorin-like hormone levels, insulin and glucose were measured at the baseline and at the end of study. Results: The level of Meteorin-like hormone was significantly decreased in control group (p=0.008, but that of Meteorin-like hormone in resistance training was increased insignificantly (p=0.311. The variations of Meteorin-like hormone levels between two groups were significant (p=0.004. The changes of insulin resistance were increased in both groups which were statistically significant (p=0.032 and insignificant (p=0.632 for control and training groups respectively. We found a negative and insignificant correlation between changes in Meteorin-like hormone levels and changes in insulin resistance index (p=0.273. Conclusion: The results showed that six weeks’ resistance training has no effect on increasing Meteorin-like hormone serum level and improving insulin resistance index and body composition in overweight adolescent boys.

    [Purpose] This study aimed to examine the correlation of visfatin level to pancreatic endocrine hormone level, homeostasis model assessment of insulin resistance (HOMA-IR) index, and HOMA β-cell index in hydraulic resistance exercise. Furthermore, it investigated the relationship between visfatin level and other variables affected by exercise in overweight women. [Subjects and Methods] The exercise group trained for 12 weeks, 70 minutes/day, 5 days/week. Visfatin level, pancreatic endocrine hormone level, HOMA-IR index, and HOMA β-cell index were measured before and after the intervention. Based on the blood insulin and glucose concentrations, HOMA-IR index, the indicator of insulin resistance, and HOMA β-cell index, the indicator of insulin secretion level, were assessed. [Results] Interaction effects on visfatin level, insulin level, HOMA-IR index, and HOMA β-cell index were observed. Interaction effects on glucagon and glucose levels were not observed between the intervention groups. The correlations of visfatin level to insulin, glucagon, and glucose levels, and HOMA-IR and HOMA β-cell indexes were not significant for any of the subjects. [Conclusion] Therefore, the 12-week resistance exercise affected body composition, visfatin level, insulin level, HOMA-IR index, and HOMA β-cell index. Finally, visfatin was not related to insulin, glucagon, and glucose levels, and HOMA-IR and HOMA β-cell indexes.

    The RARF proposes `RIKEN RI Beam Factory` as a next facility-expanding project. The factory makes it the primary aim to provide RI (Radioactive Isotope) beams covering over the whole atomic-mass range with the world-highest intensity in a wide energy range up to several hundreds MeV/nucleon. These RI beams are generated by the fragmentation of high-intensity heavy-ion beams. For the efficient production heavy-ion energies will be boosted up to over 100 MeV/nucleon even for very heavy ions by a K2500-MeV superconducting ring cyclotron serving as a post accelerator of the existing K540-MeV ring cyclotron. A new type of experimental installation called `MUSES` (Multi-USe Experimental Storage rings) will be constructed as well. With MUSES, various types of unique colliding experiments will become possible. (author)

    Bacteriological analysis of the water samples collected from upstream, midstream and downstream points along the bank of the river revealed high populations of Escherichia coli, Citrobacter freundii, Citrobacter diversus, Enterobacter aerogens and Klebsiella species. All these isolates were screened against eight antibiotics to determine the prevalence of multiple antibiotic resistance among isolates at different sites of the river. The study revealed that multiple antibiotic resistance was prominently seen in coliforms at downstream sites (Average multiple antibiotic resistance index, MAR Index = 0.43) while it was low in coliforms at upstream sites (MAR Index = 0.15). These differences in MAR indices provide a method for distinguishing high risk contamination sites in aquatic environment.

  5. Noise Resistant Generalized Parametric Validity Index of Clustering for Gene Expression Data.

    Validity indices have been investigated for decades. However, since there is no study of noise-resistance performance of these indices in the literature, there is no guideline for determining the best clustering in noisy data sets, especially microarray data sets. In this paper, we propose a generalized parametric validity (GPV) index which employs two tunable parameters α and β to control the proportions of objects being considered to calculate the dissimilarities. The greatest advantage of the proposed GPV index is its noise-resistance ability, which results from the flexibility of tuning the parameters. Several rules are set to guide the selection of parameter values. To illustrate the noise-resistance performance of the proposed index, we evaluate the GPV index for assessing five clustering algorithms in two gene expression data simulation models with different noise levels and compare the ability of determining the number of clusters with eight existing indices. We also test the GPV in three groups of real gene expression data sets. The experimental results suggest that the proposed GPV index has superior noise-resistance ability and provides fairly accurate judgements.

    Recently, Li and Pan defined the metric of the K-dimensional structure entropy of a structured noisy dataset G to be the information that controls the formation of the K-dimensional structure of G that is evolved by the rules, order and laws of G, excluding the random variations that occur in G. Here, we propose the notion of resistance of networks based on the one- and two-dimensional structural information of graphs. Given a graph G, we define the resistance of G, written , as the greatest overall number of bits required to determine the code of the module that is accessible via random walks with stationary distribution in G, from which the random walks cannot escape. We show that the resistance of networks follows the resistance law of networks, that is, for a network G, the resistance of G is , where and are the one- and two-dimensional structure entropies of G, respectively. Based on the resistance law, we define the security index of a network G to be the normalised resistance of G, that is, . We show that the resistance and security index are both well-defined measures for the security of the networks. PMID:27255783

Based on the resistance law, we define the security index of a network G to be the normalised resistance of G, that is, . We show that the resistance and security index are both well-defined measures for the security of the networks.

    The RARF has a heavy-ion accelerator complex consisting of a K540-MeV ring cyclotron as a booster accelerator and two different types of injectors. The facility provides not only nuclear physicists but also researchers of atomic physics, nuclear chemistry, material science, radiobiology and others with various kinds of heavy-ion beams of an energy range of 10 MeV/nucleon to 100 MeV/nucleon. One of remarkable features of this facility is capability of supplying RI (radioactive isotope) beams with the world-highest level of intensities. In these several years the RI beam has opened up a quite new and fascinating heavy-ion science. In order to further promote this new science, we propose open-quote open-quote RIKEN RI Beam Factory close-quote close-quote as a future project of the RARF: The existing facility will be expanded into the open-quote open-quote Factory close-quote close-quote where high-intensity RI beams of the whole mass range will become available in a wide energy range up to several hundred MeV/nucleon. The concept of this new proposal as well as currently-running upgrade programs relevant to the project will be presented. copyright 1996 American Institute of Physics

    Manufacturers have inserted a prosthetic index, an internal hexagon to guide prosthetic components inside Morse taper implants. However, it is still unclear if this mechanism could decrease the mechanical strength of Morse taper implants. The aim of this study was to evaluate the influence of the prosthetic index inside Morse taper implants on fracture resistance compared with nonindexed implants. Fifty-seven Morse taper implants, with 11.5-degree angulation of the internal conical portion, were divided into three groups: implants without the prosthetic index and solid Morse taper universal post (group 1), implants with the prosthetic index and solid Morse taper universal post (group 2), and implants and abutments with the prosthetic index (group 3). All groups were modeled for finite element stress analysis (FEA), simulating force application of a perpendicular load to the abutments. Fracture resistance (n = 10) was determined under the same condition. Dynamic loading (n = 9) was also performed. The statistical analysis was performed using one-way analysis of variance (ANOVA), and the Tukey test was applied (α = .05). The metallographic analysis was used to identify the fracture distribution and the microstructure of the titanium alloy. There was no statistically significant difference between the values of all tested groups. According to the FEA, the prosthetic index region was out of stress. The mean fracture resistances and loading test were 353.7 N and 200 N for group 1, 397.3 N and 170 N for group 2, and 372.0 N and 160 N for group 3, respectively. Metallographic analysis showed a macroscopic failure pattern just as demonstrated by FEA. The presence of the prosthetic index on Morse taper implants did not decrease its resistance to fracture for the tested implants.

    Abstract Objective: To identify cutoff points of the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) index established for adolescents and discuss their applicability for the diagnosis of insulin resistance in Brazilian adolescents. Data source: A systematic review was performed in the PubMed, Lilacs and SciELO databases, using the following descriptors: "adolescents", "insulin resistance" and "Receiver Operating Characteristics Curve". Original articles carried out with adolescents published between 2005 and 2015 in Portuguese, English or Spanish languages, which included the statistical analysis using Receiver Operating Characteristics Curve to determine the index cutoff (HOMA-IR) were included. Data synthesis: A total of 184 articles were identified and after the study phases were applied, seven articles were selected for the review. All selected studies established their cutoffs using a Receiver Operating Characteristics Curve, with the lowest observed cutoff of 1.65 for girls and 1.95 for boys and the highest of 3.82 for girls and 5.22 for boys. Of the studies analyzed, one proposed external validity, recommending the use of the HOMA-IR cutoff>2.5 for both genders. Conclusions: The HOMA-IR index constitutes a reliable method for the detection of insulin resistance in adolescents, as long as it uses cutoffs that are more adequate for the reality of the study population, allowing early diagnosis of insulin resistance and enabling multidisciplinary interventions aiming at health promotion of this population.

    Full Text Available Interpretation of resistivity cross sections may be in many cases unreliable due to the presence of artifacts left by the inversion process. One way to avoid erroneous conclusions about geological structure is creation of Depth of Investigation (DOI index maps, which describe durability of prepared model with respect to variable parameters of inversion. To assess the usefulness of this interpretation methodology in resistivity imaging method over quaternary sediments, it has been used to one synthetic data set and three investigation sites. Two of the study areas were placed in the Upper Silesian Industrial District region: Bytom - Karb, Chorzów - Chorzow Stary; and one in the Southern Pomeranian Lake District across Piława River Valley. Basing on the available geological information the results show high utility of DOI index in analysis of received resistivity models, on which areas poorly constrained by data has been designated.

    2018-03-01

    Rice is a staple food and regarded as a useful carbohydrate source. In general rice is high in glycaemic index (GI) and low colonic fermentation. People are aware of the alterations in blood glucose levels or glycaemic index after consuming rice. Resistant starch (RS) and amylose content play an important role in controlling GI. GI and RS content have been established as important indicators of starch digestibility. The aim of this study was to determine the precooked process with hydrothermal (boiling at 80°C, 10 minutes) and cooling process with low temperature (4°C, 1 h) to increase potential content of RS and decrease of glycaemic index of white rice. There were two stages of this research, 1) preparation of white rice with precooked process; 2) analysis of precooked white rice characteristics (resistant starch, amylose content, and estimated glycaemic index). The result of analysis on precooked white rice showed an increased RS content (1.11%) and white rice (0.99%), but the difference was not statistically significant. The amylose content increased significantly after precooked process in white rice (24.70%) compared with white rice (20.89%). Estimated glycaemic index (EGI) decreased after precooked proses (65.63%) but not significant as compared to white rice (66.47%). From the present study it was concluded that precooked process had no significant impact on increasing RS and decreasing EGI of white rice. This may be due to the relatively short cooling time (1hour) in 4°C.

    Conventional ultrasound (US) is reliable to reveal the presence of non-alcoholic fatty liver disease (NAFLD), but it is neither sensitive nor specific to reveal fibrosis clues, except in advanced stages where signs of cirrhosis are evident. NALFD fibrosis score is a non-invasive parameter that predicts well the presence of significant fibrosis, but correlations with US parameters are lacking. The aim of this study was, therefore, to compare resistive index of hepatic artery (HARI) of NAFLD patients with different severity degrees of diffuse fatty liver disease vs HARI of controls, and to compare HARI of NAFLD patients with different NAFLD fibrosis scores vs HARI of controls. This was a spontaneous, no-profit observational study conducted in our US department between December 2013 and July 2014. Patients with NAFLD with different severity of disease and healthy controls were included. Echogenicity and size of liver and spleen, maximum portal vein velocity, RI, peak systolic velocity (PSV), and end diastolic velocity (EDV) of splenic artery, PSV, EDV, and RI of hepatic artery, and NAFLD fibrosis score were acquired and compared between groups. HARI was significantly lower in NAFLD patients than controls (p steatosis, might suggest the execution of biopsy to predict the risk of progression to steatohepatitis and fibrous tissue accumulation. Low values of HARI may be expression of lower risk, which does not necessitate any biopsy.

    The aim of this study is to evaluate the changes in Doppler resistive index (RI) and plasma creatinine and magnesium concentrations after unilateral ureteral obstruction in a rabbit model. Fourteen adult female rabbits were used in this study. In seven rabbits, the left ureter was ligated with silk suture, and the control group was sham operated. Before surgery and on the second and seventh days after surgery, blood samples were obtained to measure plasma creatinine and magnesium concentrations. Doppler RIs of both kidneys were also measured before surgery and on the second and seventh days after the surgical procedure. With regard to magnesium levels, there was a significant within-subjects sessions difference [F(2, 20) = 15.21, P= 0.001] indicating a decrease through sessions. Magnesium concentrations decreased significantly at the postoperative second and seventh days compared to preoperative baseline levels (P= 0.003 and P= 0.001, respectively). Multifactorial analysis of variance was applied for each session separately with laterality, and groups as factors. The Doppler RI and the creatinine level did not show any significant differences or interactions for all sessions (P > 0.05). The decreasing plasma magnesium concentration after surgery may indicate ureteral injury; however, Doppler studies and creatinine levels may not be useful as well.

    Full Text Available Background: Doppler ultrasonography (DU and measurement of its indexes, resistive index (RI and pulsatility index (PI, is used to investigate transplanted kidney hemodynamic status and function. The aim of this study was to determine the correlation between Doppler indexes in the early phase after transplantation with long-term transplanted kidney function. Materials and Methods : In this cross-sectional study on 38 newly kidney transplant patients, we performed DU with assessment of its indexes within 48 hours, 1 week, and 6 months after kidney transplantation. Serum creatinine after stability and 6 months after kidney transplantation were assessed. Cyclosporine level was measured 1 week after kidney transplantation and compared with DU indexes. Results: About 71% of kidney transplanted patients reached their normal initial creatinine level(cr<1.5 mg/ dl and 28% of all patients were involved in kidney dysfunction after 6 months (increase in basic creatinine level more than 25%.There was no significant difference between mean RI and PI in patients with normal and disturbed kidney function based on creatinine level in early posttransplantation period but there was linear correlation between mean RI and PI within 48 hours and 1 week with kidney function after 6 months. Also no association between cyclosporine level and RI and PI was shown. There was a direct association between age and the levels of RI and PI 6 months after transplantation. Conclusion: This study suggests assessment of RI and PI in early period after transplantation and can be used as predictive parameters for long-term function of transplanted kidney and RI more than 0.80 in early phase after transplantation has an acceptable sensitivity and specificity to predict long-term kidney dysfunction.

  3. Increased renal resistive index in type 2 diabetes: Clinical relevance, mechanisms and future directions.

    Science.gov (United States)

    Afsar, Baris; Elsurer, Rengin

    Type 2 diabetes is a global health challenge. In type 2 diabetes both microvascular (nephropathy, retinopathy, neuropathy) and macrovascular complications arise. In kidney, renal pathological changes leading to diabetic nephropathy are mainly secondary to atherosclerosis of the intra and extra renal arteries together with microangiopathy of the glomerular capillaries, afferent arterioles and efferent arterioles. Renal resistive index (RRI) is defined as a ratio of the difference between maximum and minimum (end-diastolic) flow velocity to maximum flow velocity derived from the Doppler measurements of main renal and intrarenal (segmental/interlobar) arteries. Renal resistive index is tightly related to renal arteriolosclerosis, and represents an integrated index of arterial compliance, pulsatility and downstream microvascular impedance. In meantime, growing suggest that RRI has also been closely related with atherosclerosis. Most studies performed in type 2 diabetes showed RRI is increased in type 2 diabetes. In this review, we summarize the data regarding RRI with regard to performed studies, pathogenesis and prognosis, especially focusing on type 2 diabetes (T2D). We also review the data regarding the development of metabolic syndrome (MetS) and RRI. Copyright © 2016 Diabetes India. Published by Elsevier Ltd. All rights reserved.

    Summary: We present a review of microvascular dysfunction in hypertrophic cardiomyopathy (HCM) and an interesting case of a symptomatic familial HCM patient with inducible ischemia by single photon emission computed tomography. Coronary angiography revealed normal epicardial arteries. Pressure wire measurements of fractional flow reserve (FFR), coronary flow reserve (CFR) and index of microvascular resistance (IMR) demonstrated a significant microcirculatory dysfunction. This is the first such case that documents this abnormality invasively using the IMR. The measurement of IMR, a novel marker of microcirculatory dysfunction, provides novel insights into the pathophysiology of this condition. - Highlights: • Microvascular dysfunction is a common feature in hypertrophic cardiomyopathy (HCM) and represents a strong predictor of unfavorable outcome and cardiovascular mortality. • The index of microvascular resistance (IMR) is a new method for invasively assessing the state of the coronary microcirculation using a single pressure-temperature sensor-tipped coronary wire. • However assessment of IMR in HCM has not been previously reported. We report a case in which microvascular dysfunction is assessed by IMR. This index may be useful in future researches of HCM.

    To investigate expression difference of several drug resistance related genes between sensitive and resistant ovarian carcinoma cells. Cell lines resistant to cisplatin, carboplatin and taxol were established from ovarian carcinoma cell lines of SKOV3 and A2780, and their biological features were detected. The expressions of several genes related to drug resistance were measured by RT-PCR method. (1) The values of resistance index (RI) of resistant cells to relevant drugs were elevated 3 times or more, with different degrees of cross-resistance to several other drugs (RI 2 approximately 20). They grew more slowly than primary cells (Td elongated 1.4 approximately 2.4 times, P 0.05). Intracellular concentrations of relevant drugs were reduced 2.0 approximately 8.5 times in resistant cells (P p53, lung resistance protein-1 (LRP-1), multiple drug resistance related protein-1 (MRP-1) genes were expressed at lower levels in resistant cells than in sensitive cells; while protein kinase C (PKC), topoisomerase (topo) I, and topo II beta were expressed higher, no obvious alterations were found concerning glutathione S transferase-pi (GST-pi), and topo II alpha. Expression of multiple drug resistance-1 (MDR-1) gene was either elevated or reduced in different cells. The expressions of resistance related genes were widely different in different kinds of resistant cells, suggesting more than one pathway leading to resistance transformation. This adds more difficulties for clinical management.

  14. Generation of a predictive melphalan resistance index by drug screen of B-cell cancer cell lines.

    Directory of Open Access Journals (Sweden)

    Martin Boegsted

    Full Text Available BACKGROUND: Recent reports indicate that in vitro drug screens combined with gene expression profiles (GEP of cancer cell lines may generate informative signatures predicting the clinical outcome of chemotherapy. In multiple myeloma (MM a range of new drugs have been introduced and now challenge conventional therapy including high dose melphalan. Consequently, the generation of predictive signatures for response to melphalan may have a clinical impact. The hypothesis is that melphalan screens and GEPs of B-cell cancer cell lines combined with multivariate statistics may provide predictive clinical information. MATERIALS AND METHODS: Microarray based GEPs and a melphalan growth inhibition screen of 59 cancer cell lines were downloaded from the National Cancer Institute database. Equivalent data were generated for 18 B-cell cancer cell lines. Linear discriminant analyses (LDA, sparse partial least squares (SPLS and pairwise comparisons of cell line data were used to build resistance signatures from both cell line panels. A melphalan resistance index was defined and estimated for each MM patient in a publicly available clinical data set and evaluated retrospectively by Cox proportional hazards and Kaplan-Meier survival analysis. PRINCIPAL FINDINGS: Both cell line panels performed well with respect to internal validation of the SPLS approach but only the B-cell panel was able to predict a significantly higher risk of relapse and death with increasing resistance index in the clinical data sets. The most sensitive and resistant cell lines, MOLP-2 and RPMI-8226 LR5, respectively, had high leverage, which suggests their differentially expressed genes to possess important predictive value. CONCLUSION: The present study presents a melphalan resistance index generated by analysis of a B-cell panel of cancer cell lines. However, the resistance index needs to be functionally validated and correlated to known MM biomarkers in independent data sets in order to

    The Europlanet 2020 Research Infrastructure (RI) has received 9.945 million Euros from the European Commission to integrate planetary science across Europe, provide access to facilities, develop tools and build community cohesion. To help these processes and to increase engagement between our policy makers and the planetary science community, part of Europlanet 2020 RI's efforts are dedicated to building connections and organising activities for and within the European Parliament. Since September 2015, Europlanet 2020 RI has contacted all 134 Members of the European Parliament (MEPs) on the ITRE Committee. More than 20 individual briefings have been held to date with MEPS and/or their representatives. In November 2016, Europlanet 2020 RI organized a very successful exhibition in the European Parliament as part of the 8th European Innovation Summit and the STOA Annual Lecture, and a dinner debates was held in the on the 'Impact of the EU on planetary science' in April 2016. These events enable members of the Europlanet community, politicians and interested parties to come together and discuss views on topics of interest or concern to the space and planetary sectors. Efforts in recent years have led to important opportunities for our community to feed into reporting and consultative processes. In this talk we will discuss the results achieved in the last two years of activities and the next steps foreseen by Europlanet 2020 RI.

    Full Text Available Background: Biliary cast syndrome (BCS was a postoperative complication of orthotopic liver transplantation (OLT, and the reason for BSC was considered to relate with ischemic type biliary lesions. This study aimed to evaluate the relationship between BCS following OLT and the hepatic artery resistance index (HARI, and to observe pathological changes and morphology of biliary casts. Methods: Totally, 18 patients were diagnosed with BCS by cholangiography following OLT using choledochoscope or endoscopic retrograde cholangiopancreatography. In addition, 36 patients who did not present with BCS in the corresponding period had detectable postoperative HARI on weeks 1, 2, 3 shown by color Doppler flow imaging. The compositions of biliary casts were analyzed by pathological examination and scanning electron microscopy. Results: HARI values of the BCS group were significantly decreased as compared with the non-BCS group on postoperative weeks 2 and 3 (P 1 (OR = 1.300; 1.223; and 1.889, respectively. The OR of HARI 3 was statistically significant (OR = 1.889; 95% confidence interval = 1.166-7.490; P = 0.024. The compositions of biliary casts were different when bile duct stones were present. Furthermore, vascular epithelial cells were found by pathological examination in biliary casts. Conclusions: HARI may possibly serve as an independent risk factor and early predictive factor of BCS. Components and formation of biliary casts and bile duct stones are different.

    Obesity predicts vascular stiffness, which is prevalent among kidney transplant patients. However, the influence of obesity has not been established on parameters of renal vascular resistance variation. The aim of this study was to analyze the influence of nutritional status on intrarenal resistive parameters as measured in the early period after successful kidney transplantation by Doppler ultrasound. Both pulsatility index (PI) and resistance index (RI) in the kidney graft were measured by Doppler sonography twice: at 2 to 4 days and before hospital discharge (mean 22 days; 95% confidence interval 21-23) after transplantation. Nutritional status was scored according to World Health Organization criteria. Among 513 patients, 29 were underweight; 280, normal; 166, overweight; and 38, obese. Both PI and RI values were significantly increased consistent with recipient nutritional status (analysis of variance: P underweight or normal weight groups. Multivariate analysis revealed an influence of body mass index on PI and RI measurements before hospital discharge to be independent of other variables, including recipient age, prior delayed graft function and cold ischemia time. Excessive nutritional status was associated with increased renal vascular resistance among kidney transplant patients. Nutritional status should be considered for the proper interpretation of intrarenal Doppler measurements. Copyright © 2013 Elsevier Inc. All rights reserved.

    Many kinds of radioisotopes (RIs) produced by the high energy (100 200 MeV) proton accelerators are developed by the foreign R&D institutes and the worldwide demands are being increased continuously. The RI production using high energy proton beam higher than 50 MeV was not considerable because of the limit of the proton beam energy from existing proton accelerator facilities in Korea before 2013. The available maximum proton energy was 50 MeV from MC-50 cyclotron of Korea Institute of Radiological and Medical Sciences (KIRAMS) at that time. After the construction of a 100 MeV high-current and high-energy proton accelerator and a new irradiation facility for the RI production in 2013 and 2016 by the Korea Multi-purpose Accelerator Complex (KOMAC) at Korea Atomic Energy Research Institute (KAERI), we can make a plan for the new RI production of Cu-67, Sr-82 and so on. In the medical application fields, the worldwide demand of Sr-82 is being increased rapidly during last several years and the domestic demand of Cu-67 is also expected to be increased in near future. And alpha-emitters, such as Ac-225 and Ra-223, are becoming attractive to the users in the medical science fields in the future. The RI development plan of KOMAC was specified recently reflecting the recent environment changes and requirements from the users. In this paper, the results and present status of RI production and R&D facilities, calculation results related to the RI production yields, and future plans is presented.

    We evaluated the association of the resistive index of the prostate capsular arteries and bladder outlet obstruction severity in men with benign prostatic hyperplasia. A total of 74 patients histologically diagnosed with benign prostatic hyperplasia were ultimately enrolled in this prospective study. Urodynamics were performed by a urologist to determine bladder outlet obstruction. Baseline parameters measured in patients with benign prostatic hyperplasia were the prostate capsular artery resistive index, International Prostate Symptom Score, quality of life score, total prostate and transition zone volume, and the transition zone index. ROC curves were produced to calculate the ROC AUC and evaluate the diagnostic performance of the prostate capsular artery resistive index, International Prostate Symptom Score, obstructive symptoms, total prostate and transition zone volume, and the transition zone index for bladder outlet obstruction. Significant difference between patients with and without bladder outlet obstruction was observed in the resistive index, which showed the highest coefficient with the degree of obstruction (r = 0.712, p prostate capsular artery resistive index had the maximum AUC of 0.823. The prostate capsular artery resistive index is significantly higher in patients with benign prostatic hyperplasia related bladder outlet obstruction than in those without such obstruction. The resistive index might serve as a novel indicator to diagnose and assess bladder outlet obstruction in patients with benign prostatic hyperplasia.

    An increase in plasma branched-chain amino acids is associated with a higher risk of developing type 2 diabetes and cardiovascular diseases. However, little is known about the basal plasma amino acid concentrations in young adults. Our aim was to determine the plasma amino acid profiles of young adults and to evaluate how these profiles were modified by sex, body mass index (BMI) and insulin resistance (IR). We performed a transversal study with 608 Mexican young adults aged 19.9 ± 2.4 years who were applicants to the Universidad Autónoma de San Luis Potosí. The subjects underwent a physical examination and provided a clinical history and a blood sample for biochemical, hormonal and amino acid analyses. The women had higher levels of arginine, aspartate and serine and lower levels of α-aminoadipic acid, cysteine, isoleucine, leucine, methionine, proline, tryptophan, tyrosine, urea and valine than the men. The obese subjects had higher levels of alanine, aspartate, cysteine, ornithine, phenylalanine, proline and tyrosine and lower levels of glycine, ornithine and serine than the normal weight subjects. Subjects with IR (defined as HOMA > 2.5) had higher levels of arginine, alanine, aspartate, isoleucine, leucine, phenylalanine, proline, tyrosine, taurine and valine than the subjects without IR. Furthermore, we identified two main groups in the subjects with obesity and/or IR; one group was composed of amino acids that positively correlated with the clinical, biochemical and hormonal parameters, whereas the second group exhibited negative correlations. This study demonstrates that young adults with obesity or IR have altered amino acid profiles characterized by an increase in alanine, aspartate, proline and tyrosine and a decrease in glycine.

    Kt/V urea was established as an index of hemodialysis (HD) adequacy. The use of V urea (as derived by the Watson et al formulae) as a normalizing factor has been questioned, and alternative parameters such as body weight 0.67 (W 0.67), body surface area (BSA), resting energy expenditure (REE), high metabolic rate organ (HMRO) mass and liver size (LV) have been proposed (respective HD adequacy indices: Kt/W 0.67, Kt/BSA, Kt/REE, Kt/HMRO and Kt/LV). The present study aimed to calculate the 6 previously described normalizing factors (all obtained utilizing anthropometric variables) and to measure bioelectrical resistance (R), an independent and directly achievable biological parameter, in 481 white, disease-free individuals and 270 white prevalent HD patients, pair-matched by age, body weight and height, after stratification by sex. Further, we aimed to evaluate the effect of substituting BSA, W 0.67, REE, HMRO, LV and R for V urea as denominator in Kt/V urea on the distribution of target dialysis dose in a cohort of 1,058 white prevalent HD patients. All individuals underwent 1 single-frequency bioelectrical impedance measurement, on the nondominant side of the body, injecting 800 μA at 50 kHz alternating sinusoidal current with a standard tetrapolar technique. When comparing pair-matched disease-free men and women with HD men and women, respectively, only R was statistically significantly different (pcalculations which utilize anthropometric variables. In contrast, R is a biological parameter which can be directly measured in the clinical setting by means of a simple, low-cost, fast and repeatable procedure. Even though Kt/R is probably the most appropriate method for scaling dialysis dose among those evaluated in the present study, further work is required to develop these concepts and translate them into rigorous outcome-based adequacy targets suitable for clinical usage.

    The predictive role of Doppler Renal Resistive Index (RRI) for mortality was shown in chronic kidney disease. In selected populations of intensive care unit (ICU), RRI predicts acute kidney injury (AKI) occurrence and anticipates persistent AKI. No data are available about mortality. We investigated whether RRI assay at AKI diagnosis could predict AKI mortality in a 10-bed-mixed medical-surgical and trauma ICU of a tertiary referral teaching hospital. The association between RRI and persistent AKI at discharge was investigated. One hundred and twenty-five of 1512 patients admitted from January 2010 to March 2013 who developed AKI during ICU stay were enrolled. Kidney function was evaluated daily according to risk, injury, failure, loss and end-stage criteria. At AKI diagnosis, we measured RRI. The association between RRI at AKI diagnosis and ICU death or persistent AKI at ICU discharge was analysed by multivariable logistic regression analysis. At AKI diagnosis, RRI was 0·77 (0·70-0·88) in survivors and 0·85 in nonsurvivors (0·79-0·94) (P = 0·002). RRI values were significantly associated with ICU death (OR = 1·63-95% CI 1·06-2·49, P = 0·025). A RRI cut-off value of 0·77 was identified by receiver operating characteristic curve. Multivariate analysis selected RRI and abdominal hypertension as strongest predictors of AKI mortality. At AKI diagnosis, RRI was 0·78 (0·70-0·85) or 0·85 (0·73-0·92) (P = 0·026) in patients with or without persistent AKI at discharge. Multivariate analysis selected RRI at AKI diagnosis as the strongest predictor of persistent AKI. High RRI values at AKI diagnosis are strictly and independently associated with in-ICU mortality and persistent AKI at ICU discharge. © 2016 Stichting European Society for Clinical Investigation Journal Foundation.

    To investigate the index of homeostasis model of insulin resistance (HOMA-IR) in IgA nephropathy (IgAN) patients, and to explore the possible correlated factors contributing to insulin resistance (IR) within these patients. There were 255 IgAN patients and 45 membranous nephropathy (MN) patients in our database. We identified 89 IgAN subjects and 21 MN subjects without diabetes and undergoing glucocorticoid therapy for at least 6 months. Data regarding physical examination, blood chemistry and renal pathology were collected from 89 IgAN subjects and 21 MN subjects. Then 62 IgAN patients and 19 MN patients with chronic kidney disease (CKD) Stage 1 - 2 were selected for the comparison of HOMA-IR index, 89 IgAN patients were selected for multiple regression analysis to test for correlated factors of HOMA-IR index with IgAN patients. Comparison between IgAN and MN show that HOMA-IR index was significantly higher in IgAN patients with CKD Stage 1 - 2. After logarithmic transformation with urine protein (UPr), Ln(UPr) (b = 0.186, p = 0.008), eGFR (b = -0.005, p = 0.014), > 50% of glomeruli with mesangial hypercellularity (b = 0.285, p = 0.027) and body mass index (BMI) (b = 0.039, p = 0.008) were correlated factors of HOMA-IR index in the multiple regression analysis. IgAN patients had higher HOMA-IR index compared with MN in the stages of CKD 1 - 2. For IgAN patients, more UPr, lower eGFR, > 50% of glomeruli with mesangial hypercellularity and higher BMI were correlated with IR.

    In dogs, diabetes mellitus and hyperadrenocorticism are causes of hypertension associated with increases in vascular peripheral resistance. In human patients, the renal resistive index (ri) and pulsatility index (pi) are related to hypertension and diabetes and are used as indicators of disease severity. In this study the renal vascular resistance was measured in 12 dogs with hyperadrenocorticism, three with diabetes mellitus and four with both conditions, and the possible relationships between the two indices, blood pressure and biochemical parameters were investigated. Hypertension, defined as a systolic blood pressure more than 150 mmHg, was recorded in two of the dogs with hyperadrenocorticism and three of the dogs with hyperadrenocorticism and diabetes. The overall mean values for ri, pi and systolic blood pressure were higher in the diseased group of dogs than in 27 healthy dogs, and both indices were correlated with blood glucose concentration.

    Full Text Available Diabetic retinopathy is the most common eye complication in diabetic patients that early detection of this complication is essential. The aim of this study was to evaluate ophthalmic artery index in diabetic retinopathy by Doppler ultrasound. . In this cross-sectional study, 64 patients were studied in 4 groups (healthy, diabetic without retinopathy, background retinopathy and proliferative retinopathy. Resistance index (RI and Pulsatile Index (PI were assessed by color Doppler ultrasound. The obtained data were analyzed by ANOVA and chi-square test and ROC curve. RI in diabetic patients with proliferative retinopathy has the highest mean (0.83 and the lowest mean was observed in healthy subjects (0.54 (P <0.001 as well as in PI, the highest rate was in diabetic patients with proliferative retinopathy (1.41 and the lowest was in healthy subjects (0.92 (P <0.001. The results of our study showed that the sensitivity, specificity, positive and negative predictive values and overall accuracy of RI and PI in diabetic patients with proliferative retinopathy in the best cut-off points (0.645 and 1.0175 respectively were 100%.Ophthalmic artery index RI and PI was significantly increased in patients with diabetic retinopathy and the sensitivity and specificity for detection retinopathy was 100%. Color Doppler ultrasound method is more efficient for screening diabetic patients with retinopathy.

    The homeostatic model assessment of insulin resistance (HOMA-IR) and triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL-C) are insulin resistance indexes routinely used in clinical and population-based studies, but their short-term repeatability are not well characterized. To quantify the short-term repeatability of insulin resistances indexes and their analytes, consisting of fasting glucose and insulin for HOMA-IR, and triglyceride and high-density lipoprotein cholesterol (HDL-C) for TG/HDL-C. Prospective cohort study. A total of 102 adults 68 to 88 years old without diabetes attended an initial exam and repeat exam (mean 46 days; range 28 to 102 days). Blood samples were collected, processed, shipped, and assayed following a standardized protocol. Repeatability was quantified using the intraclass correlation coefficient (ICC) and within-person coefficient of variation (CV). Minimum detectable change (MDC95) and minimum detectable difference (MDD95) were quantified. For HOMA-IR, insulin, and fasting glucose, the ICCs were 0.70, 0.68, and 0.70; their respective within-person CVs were 30.4%, 28.8%, and 5.6%. For TG/HDL-C, triglyceride, and HDL-C, the ICCs were 0.80, 0.68, and 0.91; their respective within-person CVs were 23.0%, 20.6%, and 8.2%. The MDC95 for HOMA-IR was 2.3 and for TG/HDL-C was 1.4. The MDD95 for a sample of n=100 for HOMA-IR was 0.8 and for TG/HDL-C was 0.6. Short-term repeatability was fair to good for HOMA-IR and excellent for TG/HDL-C according to suggested benchmarks, reflecting the short-term variability of their analytes. These measurement properties can inform the use of these indexes in clinical and population-based studies.

    We sought to determine the ranges of Doppler ultrasound findings immediately after pediatric liver transplantation that are associated with successful outcomes or postoperative complications. This study included consecutive children who underwent Doppler ultrasound less than 48 hours after liver transplantation from 2001 to 2011. Operative reports and clinical outcome data were recorded. We had 110 patients (54% girls) with mean age at transplantation of 2.9 years (median, 1.3 years; range, 0-14 years) and a median follow-up interval of 3.5 years. Two pediatric radiologists reviewed ultrasound images in consensus. We computed descriptive statistics, interindex correlations, and analysis of variance. Twenty-four of 110 patients had a vascular complication, most commonly hepatic arterial thrombosis (seven patients). Compared with published adult normal values, normal pediatric Doppler parameters at postoperative day 1 trended toward higher normal velocities and resistive indexes (up to 0.95). Absent or low-velocity common hepatic artery flow less than 50 cm/s or a common hepatic artery resistive index less than 0.50 were significantly associated with hepatic artery thrombosis, whereas absent or low-velocity portal venous flow less than 30 cm/s or low-velocity hepatic venous flow less than 25 cm/s were significantly associated with vascular complications and a monotonic hepatic venous waveform was significantly associated with venous complications. Flow in a pediatric liver on the first day after transplantation is normally hyperdynamic, especially in the youngest transplant recipients, and, as a result, low velocities or resistive indexes are particularly concerning for complications. The pediatric-specific ranges of expected posttransplantation Doppler ultrasound findings presented in this article should assist in identifying normal variation and potentially life-threatening complications.

  14. Influence of the column rectangularity index and of the boundary conditions in the punching resistance of slab-column connections

    Directory of Open Access Journals (Sweden)

    O. S. PAIVA

    Full Text Available Experimental evidence indicates that both the column rectangularity index and the boundary conditions of the connection may affect the ultimate punching resistance. This paper presents general aspects of these topics and, through the analysis of experimental results of tests on 131 slabs, evaluates the accuracy and suitability of recommendations presented by ABNT NBR 6118, Eurocode 2, ACI 318 and fib Model Code 2010. Experimental results showed that the security level of normative estimates trend to reduce as the column rectangularity increases, and in some cases, the punching resistance was overestimated. Finally, adjustments are suggested in equations presented by NBR 6118 and MC2010 in order to eliminate this trend of unsafe results.

    RiTSE, the Reactor Trip Simulation Environment, is a frame and rule-base artificial intelligence (AI) application which aids nuclear power plant operators in determining if a proposed change in a state of a component or process causes safety systems to automatically shut the plant down. This paper stresses the software techniques used to implement the system. The authors demonstrate that prototypes and industrial strength systems can be built quickly and economically without expert system shells, and that integration of AI and database techniques create a novel programming paradigm

    The introduction of highly active antiretroviral therapy (HAART) has dramatically changed the prognosis of human immunodeficiency virus (HIV) infection, with a significant decline in morbidity and mortality.Changes in body fat distribution are a common finding in individuals with HIV infection being treated with antiretrovirals, and this condition (collectively termed lipodystrophy syndrome) is associated with depletion of subcutaneous fat, increased triglycerides and insulin resistance. Obesity, particularly visceral obesity, is associated with increased risk of cardiovascular disease. Therefore, estimating visceral fat distribution is important in identifying subjects at high risk for cardiovascular disease.The aim of our study was to evaluate whether perirenal fat thickness (PRFT), a parameter of central obesity, is related to ophthalmic artery resistance index (OARI), an index of occlusive carotid artery disease in HIV-1 infected patients. We enrolled 88 consecutive HIV-1-infected patients receiving highly active antiretroviral therapy for more than 12 months, in a prospective cohort study. Echographically measured PRFT and OARI, as well as serum metabolic parameters, were evaluated. PRFT and OARI were measured by 3.75 MHz convex and 7.5 MHz linear probe, respectively. The means of PRFT and OARI in HIV-1-infected patients with visceral obesity was considerably higher than in patients without it (p 0.74 (sensitivity 78.9%, specificity 82.8%). Our data indicate that ultrasound assessment of PRFT may have potential as a marker of increased endothelial damage with specific involvement of the ocular vascular region in HIV-1-infected patients.

  1. Earthquake forecast models for Italy based on the RI algorithm

    Full Text Available This study provides an overview of relative-intensity (RI-based earthquake forecast models that have been submitted for the 5-year and 10-year testing classes and the 3-month class of the Italian experiment within the Collaboratory for the Study of Earthquake Predictability (CSEP. The RI algorithm starts as a binary forecast system based on the working assumption that future large earthquakes are considered likely to occur at sites of higher seismic activity in the past. The measure of RI is the simply counting of the number of past earthquakes, which is known as the RI of seismicity. To improve the RI forecast performance, we first expand the RI algorithm to become part of a general class of smoothed seismicity models. We then convert the RI representation from a binary system into a testable CSEP model that forecasts the numbers of earthquakes for the predefined magnitudes. Our parameter tuning for the CSEP models is based on the past seismicity. The final submission is a set of two numerical data files that were created by tuned 5-year and 10-year models and an executable computer code of a tuned 3-month model, to examine which testing class is more meaningful in terms of the RI hypothesis. The main purpose of our participation is to better understand the importance (or lack of importance of RI of seismicity for earthquake forecastability.

    To investigate cut-off values for HOMA1-IR and HOMA2-IR to identify insulin resistance (IR) and metabolic syndrome (MS), and to assess the association of the indexes with components of the MS. Nondiabetic subjects from the Brazilian Metabolic Syndrome Study were studied (n = 1,203, 18 to 78 years). The cut-off values for IR were determined from the 90th percentile in the healthy group (n = 297) and, for MS, a ROC curve was generated for the total sample. In the healthy group, HOMA-IR indexes were associated with central obesity, triglycerides and total cholesterol (p 2.7 and HOMA2-IR > 1.8; and, for MS were: HOMA1-IR > 2.3 (sensitivity: 76.8%; specificity: 66.7%) and HOMA2-IR > 1.4 (sensitivity: 79.2%; specificity: 61.2%). The cut-off values identified for HOMA1-IR and HOMA2-IR indexes have a clinical and epidemiological application for identifying IR and MS in Westernized admixtured multi-ethnic populations.

    To compare an objective (VCH-1) with a manual subjective Abbé refractometer (MSAR) and evaluate the refractive index (RI)-hydration (H) relationship for the corneal stroma. Epithelial and endothelial layers were removed from a fresh postmortem ovine corneal buttons. RI was measured at both surfaces using (i) MSAR then (ii) VCH-1. The sample was weighed, slowly dehydrated under controlled conditions (2 h), and RI measures were repeated. Sample was oven dried (90°C) for 3 d to obtain dry weight and hydration at each episode of RI measurement. Average difference between individual pairs of measurements obtained using the two refractometers (ΔRI) was 0.00071 (standard deviation ± 0.0029, 95% confidence interval ± 0.0058). Root mean square difference between measurements obtained by the refractometers was 0.0024. There was no relationship between ΔRI and the mean of each measurement pair (r = 0.201, n = 40, p = 0.214). Linear regression revealed a significant relationship between RI and reciprocal of H at both surfaces as follows: anterior (i) RI = 1.355 + 0.111/H (r = -0.852, n = 20, p = <0.001), (ii) RI = 1.357 + 0.105/H (r = -0.849, n = 20, p = <0.001) and posterior (i) RI = 1.353 + 0.085/H (r = -0.882, n = 20, p = <0.001), (ii) RI = 1.350 + 0.088/H (r = -0.813, n = 20, p = <0.001). VCH-1 measurements are in good agreement with MSAR. RI at the anterior stroma was consistently higher suggesting hydration is lower by 1.10 units (6%) compared with the posterior stroma. Dehydration increased RI at both surfaces by similar rates. Current hypothetical models are useful for predicting RI from H for the posterior, but not the anterior, stroma.

    Could surrogate indexes identify insulin resistant individuals among women with polycystic ovary syndrome (PCOS)? Surrogate indexes may be able to rule in, but not rule out, insulin resistance in women with PCOS. Insulin resistance is a typical finding of women with PCOS and most clinical information on this issue is based upon surrogate indexes of insulin resistance. However, data on the performance of these indexes in PCOS women are very limited. A retrospective analysis of 406 women referred to our outpatient clinic for hyperandrogenism and/or menstrual dysfunction and submitted to hyperinsulinemic euglycaemic clamp between 1998 and 2015. In total, 375 of these women had PCOS by the Rotterdam criteria and were included in the study. Six surrogate indexes of insulin sensitivity were calculated from glucose and insulin levels, either at fasting (homeostasis model assessment (HOMA), glucose/insulin (G/I) ratio and quantitative insulin sensitivity check index (QUICKI)) or after oral glucose load (Gutt, Stumvoll0-120 and Matsuda). Overall, insulin resistance, as identified by the M-clamp value, was found in 74.9% of these women. The percentage was 59.3% in normal-weight vs 77.5% in overweight and 93.9% in obese subjects. All surrogate indexes were highly correlated with the M-clamp values. However, their ability to identify insulin resistant individuals was limited, in terms of sensitivity and especially in normal-weight subjects. ROC analysis showed similar performances of these indexes (AUC values 0.782-0.817). Potential referral bias of PCOS patients may have caused overestimation of the prevalence of insulin resistance in these women. By using surrogate indexes many subjects with PCOS may be erroneously diagnosed as insulin sensitive, especially among normal-weight women. These indexes can be used to rule in, but not rule out, insulin resistance in PCOS. Academic grants to P. Moghetti from the University of Verona. All authors declare no conflict of interest. N

  5. Pulmonary blood volume measured by RI angiocardiography

    1982-01-01

    RI angiocardiography (RACG) was performed in 81 patients with heart disease without congestive heart failure at the time, and the results were compared between the groups with mitral valve disease and other diseases. Cardiac output (CO) and pulmonary mean transit time (PMTT) were compared with the results from the dye dilution method in the same patients. PMTT directly measured by RACG was also compared with the peak to peak time (P-PT). P-PT was expressed as the distance from the right to the left peak time in radiocardiography (RCG). There were good correlations between the CO and PMTT obtained from the RI method and those of the dye dilution method (r = 0.90, r = 0.84). The ralationship between PMTT and P-PT in mitral valve disease was different from that of other diseases. The average value of PMTT was 5.2 +- 1.0 seconds, and pulmonary blood volume (PBV) was 315 +- 57 ml/m 2 in the control group. The PBV values were markedly increased in patients with mitral stenosis (558 +- 132 ml/m 2 ) and mitral regurgitation (444 +- 119 ml/m 2 ), and were slightly increased in aortic valve disease, congenital shunt disease and cardiomyopathy. The patients with ischemic heart disease had normal PBV. In mitral valve disease, the direct method using PMTT of RACG is more accurate than the presumption method using P-PT of RCG. The determination of PBV by this method is very important to observe hemodynamic states in mitral valve disease. (J.P.N.)

    Full Text Available Background Diabetic nephropathy is a progressive disease that leads to renal failure and end stage renal disease. A frequent and early manifestation of diabetic nephropathy is hyaline arteriolosclerosis. The noninvasive method for estimating the severity of arteriolosclerosis is measurement of the renal resistive index (RI. In this study, we determined whether or not normal blood glucose control, classified as an HbA1c < 5.8%, was a sufficiently low level to prevent arteriolosclerosis in patients with essential hypertension. Methods The study subjects were 93 patients with essential hypertension with HbA1c levels <5.8%. Patients with a history of medication for diabetes mellitus were excluded. Blood flow velocity of the renal interlobar arteries was assessed by a Doppler ultrasonography and the RI calculated. Results RI correlated positively with age, body mass index, pulse pressure, pulse rate and HbA1c, and negatively with diastolic blood pressure. A multivariate analysis identified age, pulse pressure and HbA1c as significant independent determinants of RI. Our data show that RI correlates with HbA1c independent of other variables, even in normoglycemic patients with HbA1c levels <5.8%. Conclusions The results of this cross-sectional study suggest that blood glucose levels should be kept as low as possible in order to prevent arteriolosclerosis in the kidney in hypertensive patients.

    We assessed the correlation between the visceral adiposity index (VAI; a useful indicator of adipose distribution and function) and homeostatic model assessment of insulin resistance (HOMA-IR) in participants with normal waist circumference. A cross-sectional study was conducted, which included 1834 Chinese adults. The blood pressure, anthropometric measurements, fasting and postprandial blood glucose, fasting insulin, and lipid profiles were measured. The VAI and HOMA-IR were calculated. Participants were divided into 4 groups according to the HOMA-IR level, and the correlation between the VAI and HOMA-IR was analyzed. The VAI gradually increased across the HOMA-IR quartiles ( P HOMA-IR ( P HOMA-IR. A logistic regression analysis indicated that VAI elevation was the main risk factor for the increased HOMA-IR in both genders. Overall, the VAI was closely correlated with the HOMA-IR in a population without central obesity.

    The article presents the result of laboratory tests for mining waste with grain size of 0 to 2 mm stabilized with cement. Used for stabilization of cement CEM I 42.5 R and blast furnace cement CEM III / A 42.5N - LH / HSR / NA and a plasticizer sealant. Cement was added to the mining waste test in the proportions of 5 - 8% in relation to the skeleton's weight. For the cemented samples, the freeze resistance test, swelling index, coefficient of permeability and pH of water leachate were tested. The addition of a cement binder resulted in diminishing the water permeability of mining waste and limiting the leaching of fine particles from the material.

    Full Text Available Background. Patients who undergo high-risk surgery represent a large amount of post-operative ICU-admissions. These patients are at high risk of experiencing postoperative complications. Renal Resistive Index was found to be related with renal dysfunction, hypertension, and posttraumatic hemorrhagic shock, probably due to vasoconstriction. We explored whether Renal Resistive Index (RRI, measured after awakening from general anesthesia, could have any relationship with postoperative complications. Methods. In our observational, stratified dual-center trial, we enrolled patients who underwent general anesthesia for high-risk major surgery. After awakening in recovery room (or during awakening period in subjects submitted to cardiac surgery we measured RRI by echo-color-Doppler method. Primary endpoint was the association of altered RRI (>0.70 and outcome during the first postoperative week. Results. 205 patients were enrolled: 60 (29.3% showed RRI > 0.70. The total rate of adverse event was 27 (18.6% in RRI ≤ 0.7 group and 19 (31.7% in RRI > 0.7 group (P=0.042. Significant correlation between RRI > 0.70 and complications resulted in pneumonia (P=0.016, septic shock (P=0.003, and acute renal failure (P=0.001 subgroups. Patients with RRI > 0.7 showed longer ICU stay (P=0.001 and lasting of mechanical ventilation (P=0.004. These results were confirmed in cardiothoracic surgery subgroup. RRI > 0.7 duplicates triplicates the risk of complications, both in general (OR 2.03 93 95% CI 1.02–4.02, P=0.044 and in cardiothoracic (OR 2.62 95% CI 1.11–6.16, P=0.027 population. Furthermore, we found RRI > 0.70 was associated with a triplicate risk of postoperative septic shock (OR 3.04, CI 95% 1.5–7.01; P=0.002.

    An increase of glomerular filtration rate after protein load represents renal functional reserve (RFR) and is due to afferent arteriolar vasodilation. Lack of RFR may be a risk factor for acute kidney injury (AKI), but is cumbersome to measure. We sought to develop a non-invasive, bedside method that would indirectly measure RFR. Mechanical abdominal pressure, through compression of renal vessels, decreases blood flow and activates the auto-regulatory mechanism which can be measured by a fall in renal resistive index (RRI). The study aims at elucidating the relationship between intra-parenchymal renal resistive index variation (IRRIV) during abdominal pressure and RFR. In healthy volunteers, pressure was applied by a weight on the abdomen (fluid-bag 10% of subject's body weight) while RFR was measured through a protein loading test. We recorded RRI in an interlobular artery after application of pressure using ultrasound. The maximum percentage reduction of RRI from baseline was compared in the same subject to RFR. We enrolled 14 male and 16 female subjects (mean age 38 ± 14 years). Mean creatinine clearance was 106.2 ± 16.4 ml/min/1.73 m(2). RFR ranged between -1.9 and 59.7 with a mean value of 28.9 ± 13.1 ml/min/1.73 m(2). Mean baseline RRI was 0.61 ± 0.05, compared to 0.49 ± 0.06 during abdominal pressure; IRRIV was 19.6 ± 6.7%, ranging between 3.1% and 29.2%. Pearson's coefficient between RFR and IRRIV was 74.16% (p RFR. Our results can lead to the development of a "stress test" for a rapid screen of RFR to establish renal susceptibility to different exposures and the consequent risk for AKI.

    Although the right ventricular stroke work index (RVSWI) is a good index for RV function, a low RVSWI is not necessarily an indicator for the need for a right ventricular assist device at the time of left VAD implantation. We here aimed to determine a more precise indicator for the need for a biventricular assist device (BiVAD). In total, 116 patients (mean age, 38 ± 14 years), who underwent hemodynamic assessments preoperatively including 12 BiVAD patients, and had been followed at our institute from 2003 to 2015, were included. Multivariate logistic regression analysis indicated that RVSWI and pulmonary vascular resistance (PVR) were independent predictors of BiVAD requirement (P 5 g/m, PVR 5, PVR > 3.7), (3) RV failure (RVSWI 3.7), and examined. Most of the patients in Group 4 (75 %), with acutely depressed hemodynamics and inflammatory responses in the myocardium, required BiVAD. Overall, patients with BiVAD had a worse survival rate as compared with those with LVAD alone. In conclusion, high PVR in addition to low RVSWI effectively predicts BiVAD requirement.

    To examine which parameters obtained from transrectal ultrasonography are accurate predictors of urodynamically-confirmed bladder outlet obstruction in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia. The records of 350 patients with complaints of lower urinary tract symptoms suggestive of benign prostatic hyperplasia were reviewed. Baseline parameters were international prostate symptom score, quality of life score, postvoid residual urine volume, prostate-specific antigen, and data obtained from uroflowmetry and transrectal ultrasonography. Urodynamic studies were carried out to determine bladder outlet obstruction. Receiver operator characteristic curves were generated to compare the accuracy of the different parameters, and the area under the curve of each parameter was calculated. Bladder outlet obstruction index positively correlated with intravesical prostatic protrusion, total prostate volume, transition zone volume, transition zone index, resistive index and prostate-specific antigen. Further, resistive index was only a significant independent variable with intravesical prostatic protrusion. Intravesical prostatic protrusion had the highest area under the curve of 0.790 among all variables, and its cut-off value was 10 mm. The positive predictive value of intravesical prostatic protrusion was 76.2%. In addition, the positive predictive value of the combined parameters intravesical prostatic protrusion and resistive index increased to 83.8%. Intravesical prostatic protrusion and resistive index are useful parameters for predicting bladder outlet obstruction in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia. In clinical practice, the combination of intravesical prostatic protrusion and resistive index on ultrasound can be diagnostic of bladder outlet obstruction. © 2016 The Japanese Urological Association.

    Glutaredoxins (GRXs) are small ubiquitous oxidoreductases involved in the regulation of the redox state in living cells. In an attempt to identify the full complement of GRXs in the arbuscular mycorrhizal (AM) fungus Rhizophagus irregularis, three additional GRX homologs, besides the formerly characterized GintGRX1 (renamed here as RiGRX1), were identified. The three new GRXs (RiGRX4, RiGRX5 and RiGRX6) contain the CXXS domain of monothiol GRXs, but whereas RiGRX4 and RiGRX5 belong to class II GRXs, RiGRX6 belongs to class I together with RiGRX1. By using a yeast expression system, we observed that the newly identified homologs partially reverted sensitivity of the GRX deletion yeast strains to external oxidants. Furthermore, our results indicated that RiGRX4 and RiGRX5 play a role in iron homeostasis in yeast. Gene expression analyses revealed that RiGRX1 and RiGRX6 were more highly expressed in the intraradical (IRM) than in the extraradical mycelium (ERM). Exposure of the ERM to hydrogen peroxide induced up-regulation of RiGRX1, RiGRX4 and RiGRX5 gene expression. RiGRX4 expression was also up-regulated in the ERM when the fungus was grown in media supplemented with a high iron concentration. These data indicate the two monothiol class II GRXs, RiGRX4 and RiGRX5, might be involved in oxidative stress protection and in the regulation of fungal iron homeostasis. Increased expression of RiGRX1 and RiGRX6 in the IRM suggests that these GRXs should play a key role in oxidative stress protection of R. irregularis during its in planta phase. PMID:26900849

    Epidemiologic studies examining circulating levels of inflammatory markers in relation to obesity and physical inactivity may aid in our understanding of the role of inflammation in obesity-related cancers. However, previous studies on this topic have focused on a limited set of markers. We evaluated associations between body mass index (BMI) and vigorous physical activity level, based on self-report, and serum levels of 78 inflammation-related markers. Markers were measured using a bead-based multiplex method among 1,703 men and women, ages 55-74 years, and with no prior history of cancer at blood draw, and selected for case-control studies nested within the Prostate, Lung, Ovarian, and Colorectal Cancer Screening Trial. Analyses were adjusted for age, sex, smoking, case-control study, physical activity, and BMI. Twelve markers were positively associated with BMI after FDR correction. ORs and 95% confidence interval (CI) for highest versus lowest levels of CCL2/MCP-1, CXCL5/ENA-78, sTNFRII, CXCL10/IP-10, CXCL6/GCP2, CCL13/MCP-4, amylin, CRP, C-peptide, CCL19/MIP-3b, insulin, and leptin were: 1.50 (1.14-1.98), 1.52 (1.12-2.05), 1.61 (1.17-2.20), 1.69 (1.25-2.28), 1.74 (1.24-2.44), 1.75 (1.22-2.50), 1.91 (1.31-2.78), 2.41 (1.36-4.25), 2.78 (1.83-4.24), 3.30 (2.28-4.78), 4.05 (2.51-6.55), and 50.03 (19.87-125.99) per 5 kg/m(2), respectively. Only CXCL12/SDF-1a was associated with physical activity (≥3 vs. <1 h/wk; OR, 3.28; 95% CI, 1.55-6.94) after FDR correction. BMI was associated with a wide range of circulating markers involved in the inflammatory response. This cross-sectional analysis identified serum markers could be considered in future studies aimed at understanding the underlying mechanisms linking inflammation with obesity and obesity-related cancers. ©2014 American Association for Cancer Research.

    The purpose of this study was to determine whether hydrocele has any effect on the volume and shape of the ipsilateral testis and can be implicated as a cause of testicular ischemia. Group 1 consisted of 23 patients with unilateral idiopathic hydrocele, whereas 30 healthy men constituted group 2. All patients underwent scrotal ultrasonography by which testicular dimensions in craniocaudal (D(cc)), anteroposterior (D(ap)), and mediolateral axes were measured, followed by calculation of the D(cc)/D(ap) ratio and testicular volume. By color Doppler analysis, the resistivity index of the subcapsular artery (RI(sc)) and the resistivity index of the intratesticular artery were determined. The mean D(cc)/D(ap) ratio +/- SD for group 1 was 1.7 +/- 0.3 (range, 1.1-2.3), significantly lower than that of group 2, which was 1.9 +/- 0.3 (range, 1.3-2.2) (P = .028). Mean testicular volume values of subjects having hydrocele for more than and less than 6 months were 13.4 +/- 7.3 and 22.5 +/- 5.1 cm3, respectively; the difference between the subgroups was significant (P = .003). For the ipsilateral testis, mean RI(sc) values were 0.70 +/- 0.06 (range, 0.60-0.80) in group 1 and 0.65 +/- 0.06 (range, 0.59-0.83) in group 2. The mean RI(sc) was significantly higher in group 1 (P = .006). Unilateral idiopathic hydrocele has a tendency for rounding rather than flattening the ipsilateral testis as well as elevating the RI(sc) on the affected side. To the best of our knowledge, no strict spectral Doppler analysis criteria have been proposed for testicular ischemia yet. Therefore, the impact of the difference of the RI(sc) should raise the suspicion for ischemia, and further research is needed to elucidate any effect on spermatogenesis.

    Insulin resistance is the pathophysiological key to explain metabolic syndrome. Although clearly useful, the Homeostasis Model Assessment index (an insulin resistance measurement) has not been systematically applied in clinical practice. One of the main reasons is the discrepancy in cut-off values reported in different populations. We sought to evaluate in a Portuguese population the ideal cut-off for Homeostasis Model Assessment index and assess its relationship with metabolic syndrome. We selected a cohort of individuals admitted electively in a Cardiology ward with a BMI validation cohort of 300 individuals (no exclusion criteria applied). From 7 000 individuals, and after the exclusion criteria, there were left 1 784 individuals. The 90th percentile for Homeostasis Model Assessment index was 2.33. In the validation cohort, applying that cut-off, we have 49.3% of individuals with insulin resistance. However, only 69.9% of the metabolic syndrome patients had insulin resistance according to that cut-off. By ROC curve analysis, the ideal cut-off for metabolic syndrome is 2.41. Homeostasis Model Assessment index correlated with BMI (r = 0.371, p < 0.001) and is an independent predictor of the presence of metabolic syndrome (OR 19.4, 95% CI 6.6 - 57.2, p < 0.001). Our study showed that in a Portuguese population of patients admitted electively in a Cardiology ward, 2.33 is the Homeostasis Model Assessment index cut-off for insulin resistance and 2.41 for metabolic syndrome. Homeostasis Model Assessment index is directly correlated with BMI and is an independent predictor of metabolic syndrome.

    The metabolic syndrome (MetSyn) is a significant risk factor for cardiovascular events, but scarce information exists about its frequency in Venezuela. In this cross-sectional study, we quantified the prevalence of the MetSyn in a probabilistic, stratified sample of 274 subjects aged > or =18 years from the Libertador district in Merida, Venezuela. Secondary outcomes were the measurement of thyroid hormones (free T4 and TSH), leptin levels, and insulin resistance index (HOMA2-IR). The frequency of MetSyn (percentage +/- 95% confidence interval) according to several diagnostic criteria was as follows: National Cholesterol Education Panel (NCEP, original): 27.4% (22.1-32.7); modified NCEP: 31.8% (26.3-37.3); International Diabetes Federation: 40.9% (35.1-46.7); Latin American Diabetes Association: 27% (21.7-32.3), and Venezuelan criteria: 31.8% (26.3-37.3). The MetSyn was more frequent in males than in females with most diagnostic criteria. The estimated prevalence of type 2 diabetes mellitus was 2.9% either according to the patients' self reports or to fasting glucose level found to be above 126 mg/dL. Abnormal HOMA2-IR index, free T4 and TSH (above the 95th percentile) were detected in 4.5%, 4.4% and 5.1% of the sample, respectively. Free T4 and TSH levels below the 5th percentile were detected in 4.4% and 4.7% of subjects respectively. These values are presented for comparisons with forthcoming studies in specific clinical populations. While studies are being conducted about the different definitions of the MetSyn in Venezuela, we recommend analyzing and publishing local research data with all the available criteria so as to allow comparisons with the results already reported in the literature.

    Gonadotropin-releasing hormone agonist (GnRHa) is used as a therapeutic agent for central precocious puberty (CPP); however, increased obesity may subsequently occur. This study compared body mass index (BMI) and insulin resistance during the first year of GnRHa treatment for CPP. Patient group included 83 girls (aged 7.0-8.9 years) with developed breasts and a peak luteinizing hormone level of ≥5 IU/L after GnRH stimulation. Control group included 48 prepubertal girls. BMI and insulin resistance-related indices (homeostasis model assessment of insulin resistance [HOMA-IR] and quantitative insulin sensitivity check index [QUICKI]) were used to compare the groups before treatment, and among the patient group before and after GnRHa treatment. No statistical difference in BMI z -score was detected between the 2 groups before treatment. Fasting insulin and HOMA-IR were increased in the patient group; fasting glucose-to-insulin ratio and QUICKI were increased in the control group (all P resistance compared to the control group. During GnRHa treatment, normal-weight individuals showed increased BMI z -scores without increased insulin resistance; the overweight group demonstrated increased insulin resistance without significantly altered BMI z -scores. Long-term follow-up of BMI and insulin resistance changes in patients with CPP is required.

    Full Text Available Objective To investigate the effect of Qianggan capsules on liver fibrosis score and insulin resistance index in patients with nonalcoholic fatty liver disease (NAFLD. Methods A total of 85 NAFLD patients who were treated in the Eighth People′s Hospital of Shanghai from August 2014 to July 2015 were enrolled and randomly divided into treatment group (45 patients and control group (40 patients. The patients in the treatment group were given Qianggan capsules, and those in the control group were given polyene phosphatidylcholine capsules. The course of treatment was 24 weeks for both groups. The changes in serum aminotransferases [aspartate aminotransferase (AST and alanine aminotransferase (ALT], homeostasis model assessment of insulin resistance (HOMA-IR, and NAFLD fibrosis score (NAFLDFS after treatment were observed in both groups. The t-test was used for comparison of continuous data between groups, before-after comparison within each group was made by paired t-test; and the chi-square test was used for comparison of categorical data between groups. Results Both groups showed significant improvements in ALT and AST levels after treatment (all P<0.01. After treatment the treatment group showed significant reductions in HOMA-IR and NAFLDFS (3.58±0.85 vs 2.48±078,t=6.40,P<0.01; -1.78±1.24 vs -2.35±0.98,t=2.40,P<0.01 and the treatment group had significantly lower HOMA-IR and NAFLDFS than the control group(12.48±0.78 vs 3.09±0.89, t=3.36, P<0.01; -2.35±0.98 vs -1.48±1.08, t=3.80, P<0.01. No serious adverse events were observed during the course of treatment. Conclusion Qianggan capsules not only reduce the levels of serum aminotransferases, but also improve insulin resistance and reduce fibrosis degree in NAFLD patients.

    2014-01-01

    Full Text Available Carol Pop de Szathmári was born in Cluj, Transylvania, on 11 January 1812. His talent for painting shone out from an early age. Being a passionate traveller, Szathmári journeyed through Europe and often crossed the Carpathian Mountains to visit Wallachia and its capital, Bucharest, where he eventually settled in 1843. An accomplished landscape and portrait painter, at ease with both watercolours and oil paints, Szathmári obtained commissions from the wealthy Wallachian boyars. Szathmári kept up constant, good relations with the successive ruling princes of Wallachia for whom he painted portraits and various other compositions. By 1848, Szathmári began to experiment with photography. The outbreak of the Russian-Ottoman War in late June 1853 saw the Romanian principalities occupied by the Russian army. In April 1854, Szathmári filled a van with his cameras and glass plates and went to the Danube to document the fighting between the Russian and Turkish armies.The result of Szathmári's bravery and hard work was a photographic album. His album, containing some two hundred images, became famous due to its presentation at the 1855 Paris World's Fair and Szathmári was awarded the Second Class Medal for his work.From that time on, photography, painting and lithography were always closely connected in Szathmári's career. In 1864 he became a member of the Société Française de Photographie in Paris and in 1870 of the one in Vienna. In 1863, he was appointed Court Painter and Photographer, a position he held for the rest of his life. In that capacity, he followed his patron, Prince Carol I, on the battlefield during the Russian-Romanian-Ottoman War of 1877, which was waged south of the Danube. Alongside martial compositions and albums, Szathmári had long been attracted by folk types and produced a large series of pictures of peasants, gypsies, postillions, merchants and artisans. He toured the fairs and the crowded streets of the town in search

    The resistance levels to glyphosate and target-site based resistance mechanisms in susceptible (S) and resistant (R) Conyza canadensis (L.) populations, which were collected from apple orchards around areas of Bohai seas and Loess Plateau in China, were investigated. Among forty C. canadensis populations, eighteen populations (45%) were still susceptible; fourteen populations (35%) evolved low resistance levels resistance to glyphosate with resistance index (RI) of 2.02 to 3.90. In contrast, eight populations (20%) evolved medium resistance levels with RI of 4.35 to 8.38. The shikimic acid concentrations in R populations were highly negative relative with the glyphosate resistance levels in C. canadensis, the Pearson correlation coefficient was -0.82 treated by glyphosate at 1.8mg/L. Three 5-enoylpyruvylshikimate 3'-phosphate synthase genes (EPSPS1, EPSPS2 and EPSPS3) were cloned in all S and glyphosate-resistant C. canadensis populations. No amino acid substitution was identified at site of 102 and 106 in three EPSPS genes, which were reported to confer glyphosate resistance in other weed species. The relative expression level of EPSPS mRNA in R populations (SD07, LN05, SHX06 and SD09) was 4.5 to 13.2 times higher than in S biotype. The Pearson correlation coefficient between EPSPS expression levels and RI was 0.79, which indicated the over expression of EPSPS mRNA may cause these R populations evolve higher resistance level to glyphosate.

    Objectives: To assess the correlation between 99 Tc m -MIBI uptake and the expression level of multidrug resistant proteins of breast cancer. Methods: Thirty patients with infiltrating ductal carcinoma were enrolled in this study. 99Tcm-MIBI scintigraphy were performed at 15 min and 90 min after injecting the tracer. The uptake of 99Tcm-MIBI were evaluated as tumor over background ratio with region of interest technique. Such indexes as early uptake ratio (EUR), delay uptake ratio (DUR) and retention index (RI) were calculated respectively. P-gp (P-glycoprotein) and MRP (multidrug resistant-associated protein) expression in surgically resected tumors were investigated by immunohistochemistry. Immunohistochemistry HPIAS-1000 image analysis system was used to determined the level of P-gp and MRP expression. The difference of P-gp and MRP level in the group with RI ≥ 0 and the group with RI 99 Tc m -MIBI on delayed scans in breast cancer. The uptake of 99 Tc m -MIBI may be not related to the levels of MRP expression. Thus 99 Tc m -MIBI scintigraphy may predict the MDR development which associated with P-gp expression in breast carcinoma. (authors)

    This prospective study was designed to investigate the utility of resistive indices(RIs) of intratesticular and epididymal arteries in inflammatory scrotal disease. Gray-scale and color Doppler ultrasonographic images were obtained in 19 consecutive patients of scrotal inflammatory disease from Nov.1993 to Oct. 1994. Eleven cases of epididymitis and 11 of epididymoorchitis(EO) were included. RIs of epididymal and centripetal arteries were calculated in 19 patients and 30 cases of control. All EO and epididymitis cases showed increased color signal at color Doppler ultrasonogram at representative sites. Mean RI of centripetal artery was 0.46±0.06 in EO and 0.66±0.07 in normal control, hence RI in EO was significantly lower than that of normal control(P<0.001). The diagnostic sensitivity was 91% when the value of 0.5 or less is estimated abnormal.Mean RI of centripetal artery was 0.67±0.07 in epididymitis, and was not significantly different from that of normal control(P=0.687). Mean RI of epididymal artery in epididymitis and EO was 0.48±0.12 and resistive index of all patients were below 0.7. Color Doppler can demonstrate the hyperemic response to scrotal inflammatory disease that it can supplement the gray scale finding leading to increased diagnostic confidence. RI of centripetal artery may be confirmative in the diagnosis of inflammatory scrotal inflammatory scrotal diseases when increased color flow on color flow imaging is present

    End-stage renal failure is still a leading cause of mortality among type 1 diabetes patients. Insulin resistance plays a larger role in type 1 diabetes disease process than is commonly recognized. Detection of diabetic nephropathy as early as possible currently offers the best chance of delaying or possibly preventing progression to end-stage disease. Renal resistive index (RI) and pulsatility index (PI), measured using renal Doppler ultrasonography, reflect intrarenal vascular resistance. The present work aimed at examining renal Doppler indices (RI and PI) in type 1 diabetic children and their relation to features of insulin resistance and other established parameters of early diabetic nephropathy as microalbuminuria. One hundred diabetic children with a mean age of 13.4 ± 2.9 yr and an average diabetes duration of (7.2 ± 2.5 yr) were included. Thirty healthy children served as controls. All renal Doppler indices were significantly higher in children with type 1 diabetes mellitus (p ≤ 0.01). The worst parameters were observed in children diagnosed with insulin resistance syndrome (IRS) (38%), hypertensive (12%), and obese (4%) children. Resistive index showed a significant correlation to blood pressure (r = 0.2, p = 0.04), waist-hip ratio (r = 0.5, p = 0.02), insulin dose (r = 0.2, p = 0.02) and estimated glucose disposal rate (r = -0.5, p = 0.01). No correlation was noted to microalbuminuria, HbA1c, or duration of diabetes. The present work concluded that renal Doppler indices are worse in diabetic children and particularly those with IRS. These children appear to be at graver risk for diabetic nephropathy. In these patients adding renal Doppler assessment to their work up, might diagnose diabetic nephropathy at a prealbuminuric stage. © 2010 John Wiley & Sons A/S.

    Full Text Available The aim of designing of the structural members is withstanding the members or structures against the different loading conditions such that the safety of the system could be preserved. The conventional method for designing of reinforced concrete members in Iranian concrete code is based on load and resistance factor. Although, load and resistance parameters are random variables, and in the mentioned Code the constant values have been designated for them during the designing procedure. Accounting these factors as the constants parameters will ultimately be led to the unsafe and uneconomical designs. The main purpose of this paper is probability-based designing of reinforcement concrete beams under simultaneous effects of bending, shear and torsion actions. For this purpose, analytical relations of the limit states for combination of bending, shear and torsion have been developed. Using the method, the structural designers could be fulfilled the designing of the RC beams based on the importance of structures and the required safety indexes of the owners.  The next goal of this investigation is evaluation and calibration of load and resistance factors for desired safety index. The economic and fully probabilistic designing of concrete beams for simultaneous effects of bending, shear and torsion are available by implementing the proposed design procedures. In order to calculate the safety indexes a computer program has been written in the MATLAB environment, and the Monte Carlo simulation technique has been utilized.

    A Schedule Optimization Study (SOS) of the US Department of Energy (DOE) Hanford Site Remedial Investigation/Feasibility Study (RI/FS) Program was conducted by an independent team of professionals from other federal agencies and the private sector experienced in environmental restoration. This team spent two weeks at Hanford in September 1992 examining the reasons for the lengthy RI/FS process at Hanford and developing recommendations to expedite the process. The need for the study arose out of a schedule dispute regarding the submission of the 1100-EM-1 Operable Unit RI/FS Work Plan. This report documents the study called for in the August 29, 1991, Dispute Resolution Committee Decision Statement. Battelle's Environmental Management Operations (EMO) coordinated the effort for DOE's Richland Field Office (RL).

    The RARF (RIKEN Accelerator Research Facility) houses an intermediate-energy heavy-ion accelerator complex consisting of a K540-MeV ring cyclotron (RRC) and a couple of different types of the injectors: a variable-frequency heavy-ion linac and a K70-MeV AVF cyclotron. One of remarkable features of this facility is capability of supplying light-atomic-mass RI (radioactive isotope) beams with the world-highest level of intensities by the projectile-fragment separator, RIPS. In these several years nuclear physicists have opened up a quite new and fascinating heavy-ion science exploiting such RI beams. In order to further promote this new science, the RARF proposes 'RIKEN RI Beam Factory' as a next facility-expanding project. The factory takes the aim at providing RI beams covering over the whole atomic-mass range with the world-highest intensities in a wide energy range up to several hundreds MeV/nucleon. To realize the 'Factory' a K2500-MeV superconducting ring cyclotron will be built which boosts output energies of the RRC beams up to 400 MeV/nucleon for light ions and up to 100 MeV/nucleon for very heavy ions, preserving their beam intensities (typically 1 pμA). RI beams will be generated by the projectile fragmentation. A new type of experimental installation called 'MUSES' (Multi-USe Experimental Storage rings) will also be constructed. It consists of an accumulator-cooler ring, booster synchrotron ring and double storage rings. With MUSES, various types of unique colliding experiments will become possible: ion-ion merging or head-on collisions; collisions of either electrons or X-rays with ion (stable isotope or RI) beams; internal target experiments; and atomic and molecular physics with cooler electron beams.

    Background: Epilepsy resistant to pharmacological treatment still remains one of the main problems in contemporary epileptology. The problem most frequently concerns patients with focal epilepsy, with the seizure focus possible to localize. In case of drug-resistant epilepsy, both morphological imaging methods (MR) and manual measurements or volumetry are used. Also functional studies, such as MRS (magnetic resonance spectroscopy), fMRI (functional magnetic resonance), SPECT (single photon emission tomography) and PET (positron emission tomography) are performed. Material/Methods: The study presents application of own computer program based on the method of segmentation of the cerebrospinal fluid (CSF) and the brain tissue. The program calculates automatically the brain-fluin index in the hippocampal region. The material comprises the brain-fluin index results calculated with the presented program in comparison with the method of manual delineation in a group of 50 patients with drug-resistant temporal lobe epilepsy. The program is easy to use, it reads the MR data recorded in DICOM installed on a PC. Results: The brain-fluin index result (expressed as a decimal fraction) is calculated on the basis of 4 consecutive layers examined by MR (evaluating hippocampal structures) performed using SE sequence, and T2-weighted imaging in the frontal plane perpendicular to the long axis of the temporal lobes. The results obtained in epilepsy patients were compared with 24 control subjects. Conclusions: Detailed analysis of the obtained data allowed to conclude that precise hippocampal volume assessment can be obtained by combination of both methods, i.e. manual delineation and automatic calculation of brain-fluin index taking into consideration the total volume of cerebral structures.

    The incidence of diabetes in Indonesia has been increasing year by year. Diets with a low glycemic index and high resistant starch foods can assist diabetics in controlling their blood glucose levels. Diabetics are known to have micro-nutrient deficiencies of chromium, magnesium and vitamin D that can be overcome by consuming parboiled rice fortified by use of a coating method. The fortification of parboiled rice (premix rice) can be achieved by coating with HPMC (hydroxypropyl methyl cellulose), MC (methyl cellulose), CMC (carboxyl methyl cellulose), gum arabic and rice starch. This research aimed to evaluate the levels of resistant starch, glycemic index and fortificants of premix rice coated with different concentrations and types of edible coating materials. This research used completely randomized design, with treatments to the concentrations and the types of edible coating (HPMC, CMC, MC, gum arabic and rice starch). The concentrations of edible coating were 0.15%, 0.2% and 0.25% for cellulose derivative coatings; 25%, 30%, 35% for gum arabic and 2%, 3.5% and 5% for rice starch. This research shows that fortified premix rice coated with various concentrations and types of edible coating materials is high in resistant starch and has a low glycemic index. The coating treatment affects the levels of magnesium and vitamin D, but does not affect the levels of chromium in parboiled rice. The premix rice with a low glycemic index and high nutrient content (chromium, magnesium and vitamin D) was premix rice coated by CMC 0.25% and HPMC 0.25% with glycemic indeces of 39.34 and 38.50, respectively.

    Common alimentary obesity frequently occurs on a polygenic basis as a typical lifestyle disorder in the developed countries. It is associated with characteristic complex metabolic changes, which are the cornerstones for future metabolic syndrome development. The aims of our study were 1) to determine the incidence of metabolic syndrome (based on the diagnostic criteria defined by the International Diabetes Federation for children and adolescents) in Czech obese children, 2) to evaluate the incidence of insulin resistance according to HOMA-IR and QUICKI homeostatic indexes in obese children with and without metabolic syndrome, and 3) to consider the diagnostic value of these indexes for the early detection of metabolic syndrome in obese children. We therefore performed anthropometric and laboratory examinations to determine the incidence of metabolic syndrome and insulin resistance in the group of 274 children with obesity (128 boys and 146 girls) aged 9-17 years. Metabolic syndrome was found in 102 subjects (37 %). On the other hand, the presence of insulin resistance according to QUICKI HOMA-IR >3.16 in 53 % of obese subjects. This HOMA-IR limit was exceeded by 70 % children in the MS(+) group, but only by 43 % children in the MS(-) group (p<0.0001). However, a relatively high incidence of insulin resistance in obese children without metabolic syndrome raises a question whether the existing diagnostic criteria do not falsely exclude some cases of metabolic syndrome. On the basis of our results we suggest to pay a preventive attention also to obese children with insulin resistance even if they do not fulfill the actual diagnostic criteria for metabolic syndrome.

    We investigate the temperature dependence of a refractive index (RI) sensor based on a macrobending micro-plastic optical fiber (m-POF) both theoretically and experimentally. The performance of the RI sensor at different temperatures (10°C-70°C) is measured and simulated over an RI range from 1.33 to 1.45. It is found that the temperature dependent bending loss and RI measurement deviation monotonically change with temperature, and the RI deviation has a higher gradient with temperature variation for a higher measured RI. Because of the linear trend of temperature dependence of the sensor, it is feasible to correct for changes in ambient temperature.

    In this paper, a novel refractive index (RI) sensor is proposed based on the fused tapered special multi-mode fiber (SMMF). Firstly, a section of SMMF is spliced between two single-mode fibers (SMFs). Then, the SMMF is processed by a fused tapering machine, and a tapered fiber structure is fabricated. Finally, a fused tapered SMMF sensor is obtained for measuring external RI. The RI sensing mechanism of tapered SMMF sensor is analyzed in detail. For different fused tapering lengths, the experimental results show that the RI sensitivity can be up to 444.517 81 nm/RIU in the RI range of 1.334 9—1.347 0. The RI sensitivity is increased with the increase of fused tapering length. Moreover, it has many advantages, including high sensitivity, compact structure, fast response and wide application range. So it can be used to measure the solution concentration in the fields of biochemistry, health care and food processing.

    The term facial acanthosis nigricans (FAN) lacks definition of precise clinical and histopathological features. We present a descriptive study of patients with FAN to define pigmentary patterns and estimate the prevalence of obesity and insulin resistance in these cases. It is a prospective study that included all patients with classical AN of the neck and/or other areas with facial acanthosis nigricans described as brown-to-black macular pigmentation with blurred ill-defined margins, found on the zygomatic and malar areas. The body mass index (BMI) and waist circumference (WC) of the included patients were used as parameters of obesity. Homeostatic Model of Assessment of Insulin Resistance (HOMA2 IR) was used as a parameter to evaluate insulin resistance. Histopathological features of the 6 skin biopsies that were possible were reviewed. Among the 102 included individuals, the patterns of facial pigmentation seen in addition to the classic pattern involving zygomatic and malar areas were a hyperpigmented band on the forehead in 59.80%, periorbital darkening in 17.64%, perioral darkening in 12.74%, and generalized darkening in 9.8% of cases. 85.29% of the males and 100% of the females were found to be obese. Varying degrees of insulin resistance was noted in 82.34% of the individuals. Six biopsies available for evaluation showed changes such as mild epidermal hyperplasia with prominent basal melanin, however, without the typical papillomatosis seen in AN of the flexures. We document an increased prevalence of obesity and insulin resistance in patients presenting with FAN and its presentations in addition to the classical description. We propose that FAN can be considered a cutaneous marker of insulin resistance and that HOMA2 IR can serve as a parameter of insulin resistance in such cases.

    The employment of gamma-ray scintillation camera with the use of short-lived radioisotopic pharmaceuticals, such as 99m Tc sodium pertechnetate, have enabled us to perform RI (radioisotopic) angiocardiography. Although conventional cardiac catheterization or angiocardiography using contrast media have been an important diagnostic tool, they may carry some risks or serious complications. The author investigated on RI angiocardiography in twelve normal and twenty five patients with cardiovascular diseases in an effort to evaluate its diagnostic value. The results obtained with this study are as follows; l. In normal subjects, the scintillation camera transit time of arm-to-right heart was found to be 2.1±0.67 seconds, right heart-to-lung 1.5±0.40 seconds and lung-to-left heart 3.5±0.86 seconds. 2. Transformation or displacement of the heart and the great vessel are easily discriminated by RI angiocardiography. Both in the cases with tricuspid atresia and tetralogy of Fallot, ventricular septal defects are well recognized by sequential RI angiocardiography. 3. It is also helpful in determining the site and extent of obstruction, and estimating the postoperative course both in the cases with superior vena cava syndrome and pulmonary stenosis. 4. Pericarditis with effusion is readily diagnosed by RI angiocardiogram showing characteristic 'dead space' between intracardiac and intrapulmonary radioactivity. 5. It was found that the diagnostic accuracy of this study was 78.4%. It is concluded that above results obtained are useful and accurate enough for the diagnostic screening method for clinical practice.

    This paper describes a successful strategy that facilitates regulatory approval of CERCLA documents required by compliance agreement and CERCLA, based on the experience of Operable Unit 1, Waste Storage Area, of the Fernald Environmental Management Project (FEMP). This strategy, which has become the site standard at the FEMP, was instrumental in obtaining regulator approval of the OU1 RI and FS, and early approval of the Record of Decision during a very tight compliance agreement-driven schedule. This strategy can be applied at any DOE Superfund site, especially where there is need to recover lost schedule, an incentive to meet milestones early, a need to improve the relationship between the DOE and the regulators, or where the regulatory agencies have historically provided a large volume of comments on CERCLA documents. The strategy focuses on early identification and resolution of issues relating to draft RI/FS documents, as raised in regulatory agency review comments. This pro-active strategy has the potential for schedule and cost savings, as well as for improved communication between DOE and the regulators. The strategy includes preparation of a separate comment response document, integration of comment responses with RI/FS documents, development of a database of agency comments and their resolution, and sharing lessons learned with preparers of subsequent RI/FS documents. The paper provides background on the FEMP and describes the FEMP comment response strategy; DOE and regulator interface; the Sitewide Comment Database; networked electronic file management; the process for classifying, analyzing, and responding to comments; integration with base RI/FS documents; and a conclusion

    The X-ray crystal structure (at 2.1 Å resolution) of an immunogen under development as part of a ricin vaccine for humans is presented and structure-based analysis of the results was conducted with respect to related proteins and the known determinants for inducing or suppressing the protective immune response. RiVax is a recombinant protein that is currently under clinical development as part of a human vaccine to protect against ricin poisoning. RiVax includes ricin A-chain (RTA) residues 1–267 with two intentional amino-acid substitutions, V76M and Y80A, aimed at reducing toxicity. Here, the crystal structure of RiVax was solved to 2.1 Å resolution and it was shown that it is superposable with that of the ricin toxin A-chain from Ricinus communis with a root-mean-square deviation of 0.6 Å over 258 C α atoms. The RiVax structure is also compared with the recently determined structure of another potential ricin-vaccine immunogen, RTA 1–33/44–198 R48C/T77C. Finally, the locations and solvent-exposure of two toxin-neutralizing B-cell epitopes were examined and it was found that these epitopes are within or near regions predicted to be involved in catalysis. The results demonstrate the composition of the RiVax clinical material and will guide ongoing protein-engineering strategies to develop improved immunogens

    Objective: To investigate the retationship between expressions of adiponectin and hepatic fibrosis markers as well as insulin resistance index in patients with non-alcoholic fatty liver disease. Methods: Serum adiponectin, type III pro-collagen (PCIII), hyaluronic acid (HA), type IV collagen (CIV), laminin levels (with ELISA) and insulin resistance index (IRI) (calculated from homeostasis model assessment) were determined in 46 patients with non-alcoholic fatty liver disease (NAFLD) and 46 controls. Results The serum adiponectin levels in patients with NAFLD were significantly lower than those in controls while the serum hepatic fibrosis markers (PCIII, HA, CIV, LN) levels and IRI were significantly higher than those in controls (P<0.05). IRI was significantly positively correlated with the hepatic fibrosis markers levels (P<0.05). Serum adiponectin levels were significantly negatively correlated with WHR, RMI, HOMA-IRI and levels of FRG, TG, FINS hepatic fibrosis markers (P<0.05 or P<0.01). Conclusion: Serum adiponectin levels were greatly reduced in patients with NAFLD, which might play important role in the increase of insulin resistance and development of hepatic fibrosis. (authors)

    We demonstrate a novel optofluidic refractive index (RI) sensor with high sensitivity and wide dynamic range based on partial reflection. Benefited from the divergent incident light and the output fibers with different tilting angles, we have achieved highly sensitive RI sensing in a wide range from 1.33 to 1.37. To investigate the effectiveness of this sensor, we perform a measurement of RI with a resolution of ca. 5.0×10-5 refractive index unit (RIU) for ethylene glycol solutions. Also, we have measured a series of liquid solutions by using different output fibers, achieving a resolution of ca. 0.52 mg/mL for cane surge. The optofluidic RI sensor takes advantage of the high sensitivity, wide dynamic range, small footprint, and low sample consumption, as well as the efficient fluidic sample delivery, making it useful for applications in the food industry.

    Women with preeclampsia, independent of obesity and glucose intolerance, exhibit insulin resistance during pregnancy. The purpose of the present study is to determine whether early diagnosis of insulin resistance during pregnancy can predict preeclampsia. Through a case-control study, 675 pregnant women were selected and their first trimester blood was taken. Their fasting blood glucose and insulin were also measured after diagnosis of preeclampsia by 20 weeks of pregnancy. Based on the experiments conducted on 675 women who were 20 weeks past their pregnancy, 375 cases with preeclampsia were selected and assigned to the case group. 35 other pregnant women were put in the control group. Diagnosis criteria for the participants included blood pressure above 140/90 and proteinuria above 300 mg or above +1. Both groups were matched according to age, parity, gestational age, and BMI. Homa-Irand rate of insulin resistance was calculated by HOMA-IR and patients were followed up. Homeostatic model assessments (HOMA-IR) revealed that the average insulin resistance increased during pregnancy among both the case and control groups. There was a significant difference between insulin resistance of these two groups in both first trimester and third trimester and after developing preeclampsia (P < 0.001, P = 0.021). Insulin-resistance of the group with preeclampsia was higher in first trimester prior to diagnosis as well as the third trimester after diagnosis compared to natural pregnancy under similar conditions. Measurement of insulin resistance in first trimester may be useful in predicting the risk of preeclampsia.

    Full Text Available Women with preeclampsia, independent of obesity and glucose intolerance, exhibit insulin resistance during pregnancy. The purpose of the present study is to determine whether early diagnosis of insulin resistance during pregnancy can predict preeclampsia. Through a case-control study, 675 pregnant women were selected and their first trimester blood was taken. Their fasting blood glucose and insulin were also measured after diagnosis of preeclampsia by 20 weeks of pregnancy. Based on the experiments conducted on 675 women who were 20 weeks past their pregnancy, 375 cases with preeclampsia were selected and assigned to the case group. 35 other pregnant women were put in the control group. Diagnosis criteria for the participants included blood pressure above 140/90 and proteinuria above 300 mg or above +1. Both groups were matched according to age, parity, gestational age, and BMI. Homa-Irand rate of insulin resistance was calculated by HOMA-IR and patients were followed up.

    other regions. The methodology for rice crop monitoring is different from that for other crops, and these characteristics make rice crop monitoring by Earth observation data more difficult and complicated. Now, Asian-RiCE team has selected four technical demonstration sites, Indonesia, Thailand, Vietnam (North and South) for Phase1A implementation (June 2013 to November 2014) to verify methodologies that estimate multi-season crop calendar, rice planted area, yield and production by the blending of Earth observation data including satellite data from SAR or optical sensor and in-situ data. We already developed some prototype systems for rice planed area mapping by SAR and agro-weather monitoring including soil moisture or drought index by microwave and optical data. These technologies would be contribute to the development of rice crop monitoring framework for Asia-RiCE. In this presentation, we introduce the framework and ongoing activities of Asia-RiCE component for GEOGLAM and developed systems for rice crop and agro-weather monitoring.

    The major adverse consequences of obesity are associated with the development of insulin resistance (IR) and adiposopathy. The Homeostasis Model Assessment-Adiponectin (HOMA-AD) was proposed as a modified version of the HOMA1-IR, which incorporates adiponectin in the denominator of the index. To evaluate the performance of the HOMA-AD index compared with the HOMA1-IR index as a surrogate marker of IR in women, and to establish the cutoff value of the HOMA-AD. The Brazilian Metabolic Syndrome Study (BRAMS) is a cross-sectional multicenter survey. The data from 1,061 subjects met the desired criteria: 18-65 years old, BMI: 18.5-49.9 Kg/m² and without diabetes. The IR was assessed by the indexes HOMA1-IR and HOMA-AD (total sample) and by the hyperglycemic clamp (n = 49). Metabolic syndrome was defined using the IDF criteria. For the IR assessed by the clamp, the HOMA-AD demonstrated a stronger coefficient of correlation (r = -0.64) compared with the HOMA1-IR (r = -0.56); p HOMA1-IR, the HOMA-AD showed higher values of the AUC for the identification of IR based on the clamp test (AUC: 0.844 vs. AUC: 0.804) and on the metabolic syndrome (AUC: 0.703 vs. AUC: 0.689), respectively; p HOMA-AD in comparison with the HOMA1-IR in the diagnosis of IR and metabolic syndrome (p > 0.05). The optimal cutoff identified for the HOMA-AD for the diagnosis of IR was 0.95. The HOMA-AD index was demonstrated to be a useful surrogate marker for detecting IR among adult women and presented a similar performance compared with the HOMA1-IR index. These results may assist physicians and researchers in determining which method to use to evaluate IR in light of the available facilities.

    Full Text Available Bran extracts (70% aqueous acetone of specialty sorghum varieties (tannin, black, and black with tannin were used to investigate the effects of sorghum phenolic compounds on starch digestibility, Estimated Glycemic Index (EGI, and Resistant Starch (RS of porridges made with normal corn starch, enzyme resistant high amylose corn starch, and ground whole sorghum flours. Porridges were cooked with bran extracts in a Rapid Visco-analyser (RVA. The cooking trials indicated that bran extracts of phenolic-rich sorghum varieties significantly reduced EGI, and increased RS contents of porridges. Thus, there could be potential health benefits associated with the incorporation of phenolic-rich sorghum bran extracts into foods to slow starch digestion and increase RS content.

    The changes on the molecular weight distribution (MWD) and particle size distribution (PSD) during hydrolysis of barley malt in isothermal mashing procedures were determined using asymmetrical flow field flow fractionation coupled to multiangle laser light scattering and refractive index (AF4/MALS/RI). Mash/trials were focused on amylolytic starch degradation. Therefore, temperatures (65, 70, and 75 °C) were selected according to α- and β-amylases range of activity. Samples were produced by triplicate, tracking amylolytic processes over time periods from 10 to 90 min in each mash/trial. AF4/MALS/RI analysis demonstrated significant differences on the values of the MWD and PSD according to the temperature/time profile used. At mashing times over 30 min at a temperature of 65 °C, when α- and β-amylase are both active, the decrease over time of the MWD and PSD was significantly higher (P < 0.005) than at 70 °C when mainly α-amylase is active. At 75 °C, also the activity of α-amylase decreased and the MWD and PSD were significantly lower (P < 0.005) than at 70 or 65 °C at any time of the procedure. The MWD and PSD of beer components influence beer palate fullness, thus AF4/ MALS/RI would be a powerful tool for breweries to adapt their technological processes to obtain beers with particular sensorial attributes. © 2017 Institute of Food Technologists®.

    Three time since 1992, we have held the symposia entitled `Joint Spectroscopy Experiments Utilizing JAERI Tandem-Booster Accelerator` at the Tokai Research Establishment. In the symposia, we have mainly discussed the plans of experiments to be done in this joint program. The joint program started in 1994. Several experiments have been made since and some new results have already come up. This symposium `Gamma-ray Spectroscopy utilizing heavy-ion, Photon and RI beams` was held at Tokai Research Establishment of JAERI. Because this symposium is the first occasion after the program started, the first purpose of the symposium is to present and discuss the experimental results so far obtained using the JAERI Tandem-Booster. The second purpose of the symposium is to discuss new possibilities of gamma-ray spectroscopy using new resources such as RI-beam and Photon-beam. The participants from RIKEN, Tohoku University and JAERI Neutron Science Research Center presented the future plans of experiments with RI-beam at each facility. Compared with these nuclear beams, photon beam provides a completely new tool for the {gamma}-ray spectroscopy, which is achieved by inverse Compton scattering between high-energy electron and laser beams. The 23 of the presented papers are indexed individually. (J.P.N.)

    The mitochondrial DNA (mtDNA) molecules of some rats obtained from the SASCO colony contain six EcoRI-sensitive sites while the mtDNA molecules of other rats obtained from the same source contain only four EcoRI sites. By mapping the positions of the EcoRI sites on the molecules relative to the D-loop it was determined that mtDNA molecules from all rats have four EcoRI sites in common, but all the mtDNA molecules of some rats have two extra EcoRI sites. EcoRI sensitivity of mtDNA molecules was shown to be maternally inherited. Construction of heteroduplex molecules failed to reveal evidence of gross nucleotide sequence changes associated with differences in EcoRI sensitivity. Images PMID:273252

    In this study, we aimed to investigate the association of dietary phytochemical index (DPI) with insulin resistance, β-cell dysfunction, and insulin sensitivity. This longitudinal study was conducted on 1141 participants of the Tehran Lipid and Glucose Study. Dietary data were collected using a validated semi-quantitative FFQ with 168 food items at baseline and DPI was calculated. Fasting serum insulin and glucose were measured at baseline and again after a 3-year of follow-up. After 3-years of follow-up, the risk of hyperinsulinemia significantly decreased by 65 (OR = 0.35, 95% CI = 0.21-0.60) and 86% (OR = 0.14, 0.07-0.29), in the third and fourth quartile categories of DPI, respectively. The occurrence of insulin resistance and insulin insensitivity in participants with higher DPI was significantly lower than the others (OR = 0.48, 95% CI = 0.25-0.93 and OR = 0.11, 95% CI = 0.05-0.24, respectively). Higher consumption of phytochemical-rich foods may have protective effects against development of insulin resistance.

    To measure the refractive index (RI) of the human corneal stroma in vivo using an objective Abbé refractometer (VCH-1) and to determine if RI of the stroma is related to age. VCH-1 was used to measure RI at the central anterior stroma immediately after lifting the flap in neophyte patients preselected for laser in situ keratomileusis. Surgical procedures continued as preplanned after measuring the RI, and in binocular cases, measurements were taken from the right eye only. Corneal flaps were created using a femtosecond laser system. Mean RI (±SD, range) and age (±SD, range) values were 1.373 (±0.006, 1.358-1.385) and 36.55 (±12.26, 18-74). A significant linear correlation was found between age and RI. Least squares regression lines equating RI with age (x, years) were of the form: RI = 1.36911 + 0.000096x (r = +0.195; n = 115; P = 0.037). Mean RI (± SD) in the 2 age groups separated by the median age (≤34 and ≥35) were 1.371 (±0.007; n = 57) and 1.374 (±0.005; n = 58). The difference was statistically significant (P = 0.018). RI of the anterior stroma in vivo tends to be increased in older patients when the corneal flap is created using a femtosecond laser device.

    exitosa, ni todos los pacientes (pt expresan mejora clínica y algunos pueden empeorar. OBJETIVO: El presente estudio está destinado a evaluar el valor del índice de resistividad renal (IR como predictor de los efectos de la revascularización renal. MÉTODOS: Entre enero de 1998 y febrero de 2001, 2933 pacientes se sometieron al ultrasonido Doppler dúplex renal. Un total de 106 de estos pacientes expresaron EAR significativa y fueron sometidos a angiografía y revascularización renal. Se midió la presión arterial (PA antes y después de la intervención, en intervalos de hasta 2 años y las medicaciones prescriptas fueron registradas. Antes de la revascularización, el IR se midió en 3 locales del riñón, con la obtención de un promedio de estas mediciones. RESULTADOS: De los 106 pacientes, 81 tuvieron IR 80. La EAR se corrigió solamente por angioplastia (PTA en 25 pts, PTA + stent en 56 pts y quirúrgicamente en 25 pts. De los pacientes que se beneficiaron de la revascularización renal; 57 de los 81 pacientes con IR 80.

    Full Text Available Abstract Background In comparison to the well established changes in compliance that occur at the large vessel level in diabetes, much less is known about the changes in compliance of the cardiovascular system at the end-organ level. The aim of this study was therefore to examine whether there was a correlation between resistance of the intrarenal arteries of the kidney and compliance of the left ventricle, as estimated by measurements of diastolic function, in subjects with type 2 diabetes. Methods We studied 167 unselected clinic patients with type 2 diabetes with a kidney duplex scan to estimate intrarenal vascular resistance, i.e. the resistance index (RI = peak systolic velocity-minimum diastolic velocity/peak systolic velocity and a transthoracic echocardiogram (TTE employing tissue doppler studies to document diastolic and systolic ventricular function. Results Renal RI was significantly higher in subjects with diastolic dysfunction (0.72 ± 0.05 when compared with those who had a normal TTE examination (0.66 ± 0.06, p Conclusion Increasing vascular resistance of the intrarenal arteries was associated with markers of diastolic dysfunction in subjects with type 2 diabetes. These findings are consistent with the hypothesis that vascular and cardiac stiffening in diabetes are manifestations of common pathophysiological mechanisms.

    The study aimed to evaluate the clinical utility of ultrasonographic intra-renal blood flow parameters, together with the wide range of different risk factors, for the prediction of contrast-induced acute kidney injury (CI-AKI) in patients with preserved renal function, referred for coronary angiography or percutaneous coronary interventions (CA/PCI). This prospective study covered 95 consecutive patients (69.5% men; median age 65 years) subject to elective or urgent CA/PCI. Data regarding 128 peri-procedural variables were collected. Ultrasonographic intra-renal blood flow parameters, including renal resistive index (RRI) and pulsatility index (RPI), were acquired directly before the procedure. CI-AKI was defined as ≥50% relative or ≥0.3 mg/dL absolute increase of serum creatinine 48 h after procedure. CI-AKI was confirmed in nine patients (9.5%). Patients with CI-AKI had higher SYNTAX score (p = 0.0002), higher rate of left main disease (p  0.69 had 78% sensitivity and 81% specificity in CI-AKI prediction. High pre-procedural RRI seems to be a useful novel risk factor for CI-AKI in patients with preserved renal function. Coronary, peripheral and renal vascular pathology contribute to the development of CI-AKI following CA/PCI.

    The purpose of the present study was to investigate the effects of a 12-week training program on serum CXC ligand 5, tumor necrosis factor α (TNF-α) and insulin resistance index in obese sedentary women. To this end, twenty-four obese sedentary women were evaluated before and after a 12-week exercise program including a brief warm-up, followed by ~45 min per session of aerobic exercise at an intensity of 60-75% of age-predicted maximum heart rate (~300 kcal/day), followed by a brief cool down, five times per week. After the exercise program, body weight, waist circumference, waist to hip ratio, percentage body fat mass, fasting glucose and insulin of participants were decreased. Furthermore, serum CXCL5 levels were significantly decreased from 2693.2 ±375.8 to 2290.2 ±345.9 pg/ml (p HOMA-IR (p < 0.001) and TNF-α (p < 0.001). Exercise training induced weight loss resulted in a significant reduction in serum CXCL5 concentrations and caused an improvement in insulin resistance in obese sedentary women.

    Full Text Available Abstract Background: Recently a myokine named irisin has been discovered that effects on obesity, metabolism and glucose homeostasis through browning white adipose tissue and thermogenesis. However, the effects of type and intensity of exercises on it have remained unclear. The purpose of this study was to evaluate the effects of two acute eccentric and concentric exercises on serum irisin level and insulin resistance in obese sedentary women. Materials and Methods: The study was quasi-experimental. 15 female students with a body mass index above 30 kg/m2 and mean age 24.86±2.87 years participated in the study. After measuring the maximal uptake oxygen of participants, they did two acute eccentric and concentric exercises using treadmill in a cross-over design within 10 days. After at least 8 hours- fasting, blood samples were collected before and immediately after each activity, to measure the levels of irisin, glucose and insulin. Data were analyzed using paired t-test and repeated measures ANOVA. In addition, Pearson correlation was used to examine the relationship between variables. Results: the irisin levels increased significantly after both types of exercises (p<0.05, that this increase in concentric activity was more than eccentric activity. Insulin resistance increased immediately after both exercises as well, that this increase in concentric exercise was statistically significant (p<0.05. Conclusion: However, both eccentric and concentric exercises had no effect on improving insulin resistance in obese women, but they can be considered as a good stimulus for the secretion of Irisin.

    To describe the development of the Systemic Lupus Erythematosus Disease Activity Index 2000 Responder Index-50 (S2K RI-50) Website (www.s2k-ri-50.com) and to assess satisfaction with its training and examination modules among rheumatologists and rheumatology fellows. The development of the Website occurred in 3 phases. The first was a deployment phase that consisted of preparing the site map along with its content. The content included the S2K RI-50 training manual, the tests and corresponding question bank, and the online adaptive training module, along with the extensive site testing. The second phase included the participation of rheumatologists and trainees who completed the Website modules. The third was a quality assurance phase in which an online survey was developed to determine the satisfaction level of its users. Further modifications were implemented per participants' recommendations. The site has been online since it was registered in September 2010. Fourteen rheumatologists and rheumatology trainees from different centers reviewed and completed the material contained in the Website. The survey revealed acceptance among rheumatologists for the Website's content, design, and presentation. The Website was rated as user-friendly and useful in familiarizing investigators with the S2K RI-50. After completion of the training and examination modules, participants reported a suitable level of preparation to implement the S2K RI-50 in clinical trials and research settings in a timely manner. The Website includes training and examination modules that familiarize rheumatologists with the S2K RI-50 and assesses their competence to use the index. This prepares them for the use of the S2K RI-50 in clinical trials and research settings.

    Ethanol has multiple effects on biochemical events in a variety of cell types, including the high-affinity immunoglobulin E receptor (FcεRI) signaling in antigen-activated mast cells. However, the underlying molecular mechanism remains unknown. To get better understanding of the effect of ethanol on FcεRI-mediated signaling we examined the effect of short-term treatment with non-toxic concentrations of ethanol on FcεRI signaling events in mouse bone marrow-derived mast cells. We found that 15 min exposure to ethanol inhibited antigen-induced degranulation, calcium mobilization, expression of proinflammatory cytokine genes (tumor necrosis factor-α, interleukin-6, and interleukin-13), and formation of reactive oxygen species in a dose-dependent manner. Removal of cellular cholesterol with methyl-β-cyclodextrin had a similar effect and potentiated some of the inhibitory effects of ethanol. In contrast, exposure of the cells to cholesterol-saturated methyl-β-cyclodextrin abolished in part the inhibitory effect of ethanol on calcium response and production of reactive oxygen species, supporting lipid-centric theories of ethanol action on the earliest stages of mast cell signaling. Further studies showed that exposure to ethanol and/or removal of cholesterol inhibited early FcεRI activation events, including tyrosine phosphorylation of the FcεRI β and γ subunits, SYK kinases, LAT adaptor protein, phospholipase Cγ, STAT5, and AKT and internalization of aggregated FcεRI. Interestingly, ethanol alone, and particularly in combination with methyl-β-cyclodextrin, enhanced phosphorylation of negative regulatory tyrosine 507 of LYN kinase. Finally, we found that ethanol reduced passive cutaneous anaphylactic reaction in mice, suggesting that ethanol also inhibits FcεRI signaling under in vivo conditions. The combined data indicate that ethanol interferes with early antigen-induced signaling events in mast cells by suppressing the function of FcεRI

    Due to its good correlation to glycemic clamp, HOMA-IR has been widely utilized as insulin resistance index in clinical and epidemiological studies involving non-alcoholic fatty liver disease carriers. However, values used for this parameter have shown large variability. To identify the HOMA-IR cut value that best distinguishes non-diabetic non-alcoholic fatty liver disease patients from a control group. One hundred sixteen non-alcoholic fatty liver disease patients were studied, diagnosed by clinical, biochemical, and liver image or biopsy criteria, and 88 healthy individuals, without any liver disease and testing for oral glucose tolerance within normality. These groups did not differ in age and gender. All were submitted to oral glucose tolerance test and blood samples were collected for glucose and insulin measurements by immunofluorometric method. HOMA-IR was calculated according to the formula: fasting insulin (microU/L) x fasting glucose (nmol/L)/22.5. NAFLD patients showed higher insulin, glycemia, and HOMA-IR values than control group, even when excluding glucose intolerant and diabetes mellitus patients by their glycemic curves. HOMA-IR 75th percentile for control group was 1.78 and the best area under the curve index was obtained for HOMA-IR values of 2.0 [AUC= 0.840 (0.781-0.899 CI 95%), sensitivity (Se): 85%, specificity (Sp): 83%] while value 2.5 showed best specificity without important loss in sensitivity [AUC=0,831 (0.773-0.888) Se = 72%, Sp = 94%]. HOMA-IR values above or equal to 2.0 or 2.5 show enhanced diagnostic value in distinguishing non-alcoholic fatty liver disease carriers from control group individuals.

    Objective Curcumin protects the liver against injury and fibrosis through suppressing hepatic inflammation, attenuating hepatic oxidative stress (OS), and inhibiting hepatic stellate cells (HSCs) activation. Non-alcoholic fatty liver disease (NAFLD) and polycystic ovary syndrome (PCOS) are considered as common metabolic disorders. Low-grade chronic inflammation with different markers, such as elevated C-reactive protein (CRP) and interleukin-6 (IL-6) levels, play a crucial role in PCOS. This study aimed to evaluate the therapeutic effects of curcumin on IL-6 and CRP levels as well as insulin resistance (IR) index on liver function in PCOS rats. Materials and Methods In this experimental study, 90 adult Wistar rats were divided into control (n=18), sham (n=18), PCOS (n=18) and curcumin-treated PCOS groups (n=36). PCOS group was injected subcutaneously with 2 mg estradio-valerate (E2V). After 60 days, PCOS group was treated with curcumin [100 and 300 mg/kg body weight (BW)] for 14 days and anesthetized by chloroform. Blood and liver samples were collected for histological and serological analyses. Data were analyzed using In-Stat 3 via one-way analysis of variance (ANOVA). Results Histological and serological analyses showed a reduction in number of necrotic cells, IR index, as well as IL-6 and CRP levels in PCOS rats that were treated with various concentrations of curcumin. Conclusion In this study, curcumin decreased liver inflammation by induction of insulin sensitivity and reduction of hepatic necrosis. Therefore, curcumin may be considered as protective factor against inflammatory state of PCOS. PMID:28836404

    We have developed the RI plethysmography, and have applied it to ordinary clinic diagnosis and the evaluation of treatment. The subjects were 58 cases (39 cases of the obstruction of the peripheral blood circulation: ASO 24 cases, TAO 4 cases and arterial sclerotic change 11 cases; the non-abnormal control was 19 cases). The clinical benefit of this method was evaluated. In the cases with 1 and 2 degrees of Fontaine`s classification and ASO and TAO, the blood flow of legs measured by our method significantly decreased in association with symptoms and angiographic findings. This method is suitable to the determination of angiography and evaluation of the effect of treatment. (author)

    This report presents the pressure drop, vibration and endurance test results for IR rig for RI production which were desigened and fabricated by KAERI. From the pressure drop test results, it is noted that the flow rate through the IR rig corresponding to the pressure drop of 200 kPa is measured to be about 3.12 kg/sec. Vibration frequency for the IR rig ranges from 13 to 17 Hz. RMS(Root Mean Square) displacement for the IR rig is less than 30 μm, and the maximum displacement is less than 110μm. These experimental results show that the design criteria of IR rig meet the HANARO limit conditions. Endurance test results show that the appreciable fretting wear for the IR rig does not occur, however tiny trace of wear between contact points is observed

    Of RI image data processing machines, the exchangeability of data between the VIP-450 system (Ohio-Nuclear Inc.) and the DAP-5000N system (Toshiba Co.) was examined. The exchangeability requires uniformity of arrangement of bits and the data sequence between the machines. Otherwise, the form of memory of either machine should be changed. The exchangeability of data between the machines would have the following advantages: characteristic programs of each machine can be used for the same data, producing more valuable information. Data collection can be performed by any machine, increasing the efficiency of examination. It is not necessary to provide all machines with special attachments. It permits data input into large machines or minicomputers in the development of programs. (Chiba, N.)

    In order to avoid the integral bottleneck of conventional SCF calculations, the Resolution of the Identity (RI) method is used to obtain an approximate solution to the Hartree-Fock equations. In this approximation only three-center integrals are needed to build the Fock matrix. It has been implemented as part of the NWChem package of portable and scalable ab initio programs for parallel computers. Utilizing the V-approximation, both the Coulomb and exchange contribution to the Fock matrix can be calculated from a transformed set of three-center integrals which have to be precalculated and stored. A distributed in-core method as well as a disk based implementation have been programmed. Details of the implementation as well as the parallel programming tools used are described. We also give results and timings from benchmark calculations

    The pneumonia severity index (PSI) both contains some risk factors of drug-resistant pathogens (DRPs) and represents the severity of health care-associated pneumonia. The aim of this study was to investigate whether the PSI could be used to predict DRPs and whether there were risk factors beyond the PSI. A retrospective observational study enrolled 530 patients with health care-associated pneumonia who were admitted from January 2005 to December 2010 in a tertiary care hospital. A total of 206 patients (38.9%) had DRPs, of which the most common was Pseudomonas aeruginosa (24.3%). The incidence of DRPs increased with increasing PSI classes (6.7%, 25.5%, 36.9%, and 44.6% in PSI II, III, IV, and V, respectively). An analysis of the risk factors for DRPs by PSI classes revealed that wound care was associated with methicillin-resistant Staphylococcus aureus (MRSA) infection in PSI V (p = 0.045). Nasogastric tube feeding (odds ratio, 3.88; 95% confidence interval, 1.75-8.60; p = 0.006), and bronchiectasis (odds ratio, 3.12; 95% confidence interval, 0.66-14.69; p = 0.007) were risk factors for DRPs in PSI III and IV. The area under the receiver operating characteristic curve progressed from 0.578 to 0.651 while integrating these risk factors with PSI classes. The findings suggested that PSI plus risk factors predicted the risk of DRPs. PSI II had a low risk of DRPs and could be treated as community-acquired pneumonia. Antibiotics of PSI III and IV with risk factors could be targeted DRPs. PSI V with wound care had a higher risk of MRSA, and empirical anti-MRSA antibiotics could be added. Copyright © 2015.

    Full Text Available Located in Turkey's southeastern tip, her name being remembered when the subject of news is on security or garbage-fed people, Hakkâri, being at the bottom in terms of socio-economic indicators, can be appropriately qualified as other. The city has been abstracted from the country‟s other areas because of spatial problems caused by lack of transportation facilities as well as of historical political reasons arising from socio-economic structure. Being already poor in 1990s, the city‟s problems increased since people have been forced to migrate to city. With social problems experienced in the southeast of the country and in the key areas where forced migration and poverty issues are important, the city of Hakkâri is one of the most typical settlements that should be investigated on migration and poverty issues. In this context, we have conducted extensive observations and interviews in neighborhoods that have got the most migration, added to these were that detailed survey for 160 households was made and frequencies and cross-analysis for survey questions were conducted. Conducted analysis shows that migration after 1990s is the result of obligatory reasons. It is also identified that already poor in the rural areas with limited agricultural base, people moving to city has entered into absolute poverty. Briefly stated, the aim of this study is to determine whether there exist the relationship between the fact of migration and poverty and to put urban poverty‟s social, economic and spatial dimensions in place

  11. Optimal cutoff for the evaluation of insulin resistance through triglyceride-glucose index: A cross-sectional study in a Venezuelan population [version 3; referees: 2 approved

    Directory of Open Access Journals (Sweden)

    Juan Salazar

    2018-01-01

    Full Text Available Background: Insulin resistance (IR evaluation is a fundamental goal in clinical and epidemiological research. However, the most widely used methods are difficult to apply to populations with low incomes. The triglyceride-glucose index (TGI emerges as an alternative to use in daily clinical practice. Therefore the objective of this study was to determine an optimal cutoff point for the TGI in an adult population from Maracaibo, Venezuela. Methods: This is a sub-study of Maracaibo City Metabolic Syndrome Prevalence Study, a descriptive, cross-sectional study with random and multi-stage sampling. For this analysis, 2004 individuals of both genders ≥18 years old with basal insulin determination and triglycerides < 500 mg/dl were evaluated.. A reference population was selected according to clinical and metabolic criteria to plot ROC Curves specific for gender and age groups to determine the optimal cutoff point according to sensitivity and specificity.The TGI was calculated according to the equation: ln [Fasting triglyceride (mg / dl x Fasting glucose (mg / dl] / 2. Results: The TGI in the general population was 4.6±0.3 (male: 4.66±0.34 vs. female: 4.56±0.33, p=8.93x10-10. The optimal cutoff point was 4.49, with a sensitivity of 82.6% and specificity of 82.1% (AUC=0.889, 95% CI: 0.854-0.924. There were no significant differences in the predictive capacity of the index when evaluated according to gender and age groups. Those individuals with TGI≥4.5 had higher HOMA2-IR averages than those with TGI <4.5 (2.48 vs 1.74, respectively, p<0.001. Conclusions: The TGI is a measure of interest to identify IR in the general population. We propose a single cutoff point of 4.5 to classify individuals with IR. Future studies should evaluate the predictive capacity of this index to determine atypical metabolic phenotypes, type 2 diabetes mellitus and even cardiovascular risk in our population.

    Contribute evidence towards the complex interrelationships of body composition, insulin sensitivity and protein intake independently from adiposity in an older population. This is a cross-sectional analysis of an existing dataset in which a literature-supported model linking together the variables of interest is tested using path analysis. The loss of muscle mass has been implicated in the development of insulin resistance. We propose to test associations of muscle mass with insulin sensitivity and their respective associations with animal and vegetable sources of protein intake, independently from adiposity. Non-diabetic participants aged 68-82 years from the NuAge study with all available measures (n=441) were included. A model considering age, sex, chronic diseases, physical activity; smoking and sources of protein intake influencing body composition components and insulin sensitivity was created and tested with Path Analysis for their independent associations. Muscle mass index (MMI; kg/height in m2) and % body fat were derived from DXA and BIA. Insulin resistance was estimated by the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) score and physical activity by the Physical Activity Scale for the Elderly (PASE) questionnaire. Protein intakes were obtained from three non-consecutive 24h-diet recalls. In the final model, direct positive associations were observed between HOMA-IR score and MMI (ß=0.42; 95%CI: 0.24; 0.6) and % body fat (ß=0.094; 95%CI: 0.07; 0.11). There were no direct associations between animal protein intake and MMI or with HOMA-IR. There was a significant direct negative association between plant protein intake and MMI (ß= -0.068; 95%CI: -0.13; -0.003) and significant indirect associations mediated through MMI and % body fat between HOMA-IR and animal protein intake (ß=0.0321; 95%CI: 0.01; 0.05), as well as plant protein intake (ß= -0.07; 95%CI: -0.1; 0.0). Our final model indicated that MMI and HOMA score were significantly

    A compact, cost-effective and high sensitivity fiber interferometer refractive index (RI) sensor based on symmetrical offset coreless silica fiber (CSF) configuration is proposed, optimized and demonstrated. The sensor is formed by splicing a section of CSF between two CSF sections in an offset manner. Thus, two distinct optical paths are created with large index difference, the first path through the connecting CSF sections and the second path is outside the CSF through the surrounding media. RI sensing is established from direct interaction of light with surrounding media, hence high sensitivity can be achieved with a relatively compact sensor length. In the experimental work, a 1.5 mm sensor demonstrates RI sensitivity of 750 nm/RIU for RI range between 1.33 and 1.345. With the main attributes of high sensitivity and compact size, the proposed sensor can be further developed for related applications including blood diagnosis, water quality control and food industries.

    Understanding the relationship between acid detergent lignin (ADL) and lodging resistance index (LRI) is essential for breeding new varieties of brown midrib (bmr) sudangrass (Sorghum sudanense (Piper) Stapf.). In this study, bmr-12 near isogenic lines and their wild-types obtained by back cross breeding were used to compare relevant forage yield and quality traits, and to analyze expression of the caffeic acid O-methyltransferase (COMT) gene using quantitative real time-PCR. The research showed that the mean ADL content of bmr-12 mutants (20.94 g kg(-1)) was significantly (P bmr-12 mutants (0.29) was significantly (P bmr-12 materials (r = -0.44, P > 0.05). Sequence comparison of the COMT gene revealed two point mutations present in bmr-12 but not in the wild-type, the second mutation changed amino acid 129 of the protein from Gln (CAG) to a stop codon (UAG). The relative expression level of COMT gene was significantly reduced, which likely led to the decreased ADL content observed in the bmr-12 mutant.

    The aim of this study is to investigate the association between fractional flow reserve (FFR) values and change in coronary physiological indices after elective percutaneous coronary intervention (PCI). Decision making for revascularization when FFR is 0.75-0.80 is controversial. A retrospective analysis was performed of 296 patients with stable angina pectoris who underwent physiological examinations before and after PCI. To investigate the differences of coronary flow improvement between territories with low-FFR (zone FFR (0.75-0.80), serial changes in physiological indices including mean transit time (Tmn), coronary flow reserve (CFR), and index of microcirculatory resistance (IMR) were compared between these two groups. Compared to low-FFR territories, grey-zone FFR territories showed significantly lower prevalence of Tmn shortening, CFR improvement, and decrease in IMR (Tmn shorting, 63.9% vs. 87.0%, P 51.3% vs. 63.3%, P = .040) and lower extent of their absolute changes (Tmn shorting, 0.06 (-0.03 to 0.16) vs. 0.22 (0.07-0.45), P zone FFR. Physiological assessment combining FFR and IMR may help identify patients who may benefit by PCI, particularly those in the grey zone. © 2018 Wiley Periodicals, Inc.

    Many interfering factors may reduce the reliability of waist circumference (WC) measurement in estimating the risk for chronic kidney disease (CKD) associated with obesity. Therefore, we determined the independent associations of para- and perirenal ultrasonographic fat thickness with the main markers of kidney function. A cross-sectional study was performed in 151 type-2 diabetic subjects. Para- and perirenal fat thickness was measured from the inner side of the abdominal musculature to the surface of the kidneys. CKD was defined as eGFR perirenal fat thickness even when BMI and waist circumference were further added in the statistical model (r(2): 0.366, P = 0.001; r(2): 0.529, P = 0.005; r(2): 0.310, P = 0.026, respectively), whereas waist circumference and BMI did not contribute independently of para- and perirenal fat thickness. Albuminuria was predicted by waist circumference but not by para- and perirenal fat thickness. In subjects with waist circumference above the diagnostic values of metabolic syndrome (48M/59F), eGFR significantly and progressively declined across tertiles of para- and perirenal fat thickness (87.0 ± 27.9 vs 83.5 ± 26.0 vs 62.3 ± 30.6 mL min(-1) 1.73 m(-2), adjusted P perirenal fat thickness is an independent predictor of kidney dysfunction in type-2 diabetes explaining an important proportion of the variance of eGFR, renal resistance index and uricaemia.

    This manual provides detailed guidance on Remedial Investigation/Feasibility Studies (RI/FSs) conducted pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) at Department of Energy (DOE) facilities. The purpose of the RI/FS, to assess the risk posed by a hazardous waste site and to determine the best way to reduce that risk, and its structure (site characterization, risk assessment, screening and detailed analysis of alternatives, etc.) is defined in the National Oil and Hazardous Substances Pollution Contingency Plan (NCP) and further explained in the Environmental Protection Agency`s (EPA`s) Guidance for Conducting Remedial Investigations and Feasibility Studies Under CERCLA (Interim Final) 540/G-89/004, OSWER Directive 9355.3-01, October 1988. Though issued in 1988, the EPA guidance remains an excellent source of information on the conduct and structure of an RI/FS. This document makes use of supplemental RI/FS-related guidance that EPA has developed since its initial document was issued in 1988, incorporates practical lessons learned in more than 12 years of experience in CERCLA hazardous site remediation, and drawing on those lessons, introduces the Streamlined Approach For Environmental Restoration (SAFER), developed by DOE as a way to proceed quickly and efficiently through the RI/FS process at DOE facilities. Thus as its title implies, this guidance is intended to describe in detail the process and component elements of an RI/FS, as well as techniques to manage the RI/FS effectively.

    Full Text Available Objective: This longitudinal prospective observational type study was conceived with the aim to examine the impact on renal resistive index (RRI of the variables that we can manipulate with therapeutic and or dietetic interventions in a chronic kidney disease population in order to known which of these variables was statistically related to changes in RRI and therefore could become the object of the greatest therapeutic effort. Material and methods: This study was undertaken between May 2016 to May 2017 in the outpatient nephrology and urology clinic of San Donato Hospital in Arezzo. The study population (84 patients: 47 males and 37 females was randomly selected among the chronic kidney patients (with various degrees of renal impairment affected by hypertension and or diabetes mellitus. After a comprehensive medical examination these patients were submitted to determination of serum creatinine, glycated hemoglobin, 24-hour urinary albumin excretion and finally renal Doppler ultrasonography. Then the patients were submitted to a full therapeutic and dietetic intervention to ameliorate the renal impairment by a wide range of actions and after on average a one-year interval were submitted again to a new medical examination and a second determination of serum creatinine, glycated hemoglobin, 24-hour urinary albumin excretion and a new renal Doppler ultrasonography too. Results: The comparison between basal and final data revealed a slight reduction in the mean of bilateral renal resistance indices (Delta RRI: -0.0182 ± 0.08, associated to a slight increase in the mean glomerular filtration rate (Delta GFR: 0.8738 ± 10.95 ml/min/1.73 m2, a reduction in mean body weight (Delta weight: -1.9548 ± 5.26 Kg and mean BMI (Delta BMI: -0.7643 ± 2.10 Kg/m2 as well as a reduction in the mean systolic blood pressure (Delta systolic blood pressure: -8.8333 ± 25.19 mmHg.

    Acute kidney injury (AKI) following major heart surgery (MHS) is associated with early decrease in renal blood flow and worsened prognosis. Doppler-derived renal resistive index (RRI), which reflects renal vascular resistance, may predict the development of AKI in patients undergoing MHS. We studied 60 consecutive patients (mean age 69.5 years, range 30-88, 41 males) undergoing MHS. We measured RRI, both at the renal sinus and intraparenchymally, by transesophageal echo-Doppler ultrasound (TE-ED us ) at anesthesia induction and at the end of surgery in all patients. Additionally, we measured RRI by external transparietal echo-Doppler ultrasound (TP-ED us ) at the following time points: anesthesia induction, end of surgery, 4 and 24 h from cardiopulmonary bypass (CPB) start. We also measured serum neutrophil gelatinase associated lipocalin (NGAL) at the same time points. AKI [serum creatinine (sCr) increase ≥0.3 mg/dl vs. baseline within 72 h] developed in 23/60 (38.3 %) patients, with two requiring dialysis. Systemic hemodynamic parameters were similar in the patients who developed AKI (AKI+) and in those who did not (AKI-). Intraparenchymal RRI at end-surgery was significantly higher in AKI+ compared to AKI- patients, both at TE-ED us and TP-ED us (TE-ED us mean difference, p = 0.004; TP-ED us mean difference, p = 0.013; difference between TE-ED us and TP-ED us results, p = 0.066), although the predictive performance was limited with both methods (area under the curve [AUC] of the receiver-operator characteristics: 0.71 and 0.70 for TE-ED us and TP-ED us , respectively). Serum NGAL values were higher in AKI + than in AKI- patients (anesthesia induction, p = 0.037; end-surgery, p = 0.007; 4 h from CPB start, p = 0.093; 24 h from CPB start, p = 0.024. However, combining RRI with serum NGAL at end-surgery did not provide a clear-cut advantage in predicting AKI. In patients undergoing MHS, increased echo-Doppler ultrasound-derived RRI at end

    Agrobacterium strains containing a Ti plasmid can transfer T-DNA not only to plants but also to fungi, including the yeast Saccharomyces cerevisiae. However, no Agrobacterium strain harboring an Ri plasmid has been evaluated in fungal transformation. Some Ri plasmids have GALLS , instead of virE1 and virE2. GALLS protein can functionally substitute in plant transformation for a structurally different protein VirE2. In this study, we compared the yeast transformation ability among Agrobacterium donors: a strain containing a Ti plasmid, strains harboring either an agropine-type or a mikimopine-type Ri plasmid, and a strain having a modified Ri plasmid supplemented with a Ti plasmid type virE operon. Agrobacterium strains possessing GALLS transformed yeast cells far less efficiently than the strain containing virE operon. Production of GALLS in recipient yeast cells improved the yeast transformation mediated by an Agrobacterium strain lacking neither GALLS nor virE operon. A reporter assay to detect mobilization of the proteins fused with Cre recombinase revealed that VirE2 protein is much more abundant in yeast cells than GALLS. Based on these results, we concluded that the low yeast transformability mediated by Agrobacterium strains having the Ri plasmid is because of low amount of mobilized GALLS in yeast cells. © 2012 The Authors Journal compilation © 2012 by the Molecular Biology Society of Japan/Blackwell Publishing Ltd.

  8. High-molecular-weight adiponectin is selectively reduced in women with polycystic ovary syndrome independent of body mass index and severity of insulin resistance.

    LENUS (Irish Health Repository)

    O'Connor, A

    2010-03-01

    Context: High-molecular-weight (HMW) adiponectin contributes to insulin resistance (IR), which is closely associated with the pathophysiology of polycystic ovary syndrome (PCOS). Abnormalities in adipocyte function have been identified in PCOS and potentially contribute to lower adiponectin concentrations. Objective: Our objective was to determine which variables in plasma and adipose tissue influence HMW adiponectin in a well characterized cohort of women with PCOS. Design: This was a cross-sectional study. Settings and Participants: A teaching hospital. Women with PCOS (n = 98) and body mass index (BMI)-matched controls (n = 103) (including 68 age-, BMI-, and IR-matched pairs). Interventions: A standard 75-g oral glucose tolerance test was performed for each participant. Subcutaneous adipose tissue samples were taken by needle biopsy for a subset of PCOS women (n = 9) and controls (n = 8). Main Outcome Measures: Serum levels of HMW adiponectin and their relation to indices of insulin sensitivity, body composition, and circulating androgens as well as adipose tissue expression levels of ADIPOQ, TNFalpha, PPARgamma, and AR were assessed. Results: HMW adiponectin was significantly lower in women with PCOS compared with both BMI- and BMI- and IR-matched controls (P = 0.009 and P = 0.027, respectively). Although BMI and IR were the main predictors of HMW adiponectin, an interaction between waist to hip ratio and plasma testosterone contributed to its variance (P = 0.026). Adipose tissue gene expression analysis demonstrated that AR and TNFalpha (P = 0.008 and P = 0.035, respectively) but not ADIPOQ mRNA levels were increased in PCOS compared with controls. Conclusions: HMW adiponectin is selectively reduced in women with PCOS, independent of BMI and IR. Gene expression analysis suggests that posttranscriptional\\/translational modification contributes to reduced HMW adiponectin in PCOS.

    Formaldehyde is an intermediate in the atmospheric oxidation of nearly every volatile organic compound (VOC) and is important to odd-hydrogen radicals and ozone chemistry. It is directly observed from space and its distributions are used to constrain biogenic emissions of VOCs, specifically isoprene. The relative contribution of fossil VOCs and biogenic VOCs to formaldehyde, to isoprene emission estimates and subsequently to ozone and oxidant chemistry is expected to vary seasonally and spatially due to VOC speciation, emission patterns, and reactivity. The radiocarbon, 14C, content of formaldehyde is useful in assessing the relative contributions of fossil and biogenic VOC groups to formaldehyde. We report a compound specific radiocarbon analysis (CSRA) method for formaldehyde based upon gaseous formaldehyde collection, derivatization to thiazolidine, preparative capillary gas chromatography separation, and AMS analysis. Ambient measurements from Narragansett, RI, made in winter and summer 2007 are presented. On 11 of 13 samples, we find 80 to >95% of the collected formaldehyde is of fossil origin and, contrary to our initial hypothesis, we see no seasonal shift in proportion. The remaining 2 samples, one each from winter and summer, are 30-40% biogenic carbon. The measurements are interpreted considering fossil-biogenic source attribution and local transport conditions and contrasted with prior measurements from Nova Scotia. Further, CSRA measurement of acetaldehyde is feasible with the method.

    It has long been recognized in the nuclear industries and the regulatory body that exemption from the regulatory control for a given practice or source of radioactive materials, which is very low radiation exposure situation where the level of risk to any of the public would be considered as trivial, may be beneficial and practical. Therefore, it is necessary to establish the exempt levels of radioactive wastes for unconditional disposal, incineration, recycle and reuse of slightly contaminated materials. In Korea, from its announcement of the Enforcement Regulation of Atomic Energy Act, the Article 97 (Exemption from Permanent Disposal) for very low-level waste disposal in January 1990, the KINS (Korea Institute of Nuclear Safety) have made their efforts to establish a de minimis level (a level of radioactivity in waste that is sufficiently low that the waste can be disposed of as ordinary, non-radioactive trash) for short-lived radioisotopes commonly used in medical, research institutes and industrial applications and to study the possibility for unrestricted deregulation of those radioisotopes. As one of preliminary works to predict environmental radiological impacts from uncontrolled and unrestricted release of RI waste, an average effective dose to any ordinary individual and a collective dose for total population in Korea was estimated, based on conservative assumptions and Korean specific environment data, by an equilibrium biosphere models with a generic probabilistic risk approach

    We have been developing a new laser spectroscopic technique 'OROCHI,' which is based on the combination of superfluid helium as a stopper of radioactive isotope (RI) beam and in-situ laser spectroscopy of RI atoms, for determining spins and moments of exotic RIs. By using this unique technique, it is feasible to measure nuclear spins and electromagnetic moments of extremely low yield RI (estimated as less than 1 pps). Recently, we have demonstrated that nuclear spins and moments are obtained from Zeeman and hyperfine splittings of stable Rb isotopes measured using this OROCHI technique. Details of this laser spectroscopy method in He II 'OROCHI' and the summary of our development are presented.

    Experimental studies have shown that nanoparticles play an important role on the rotator phase transitions of n-alkanes. A phenomenological model for predicting the RII -RI -RV phase transitions in mixtures of alkanes and nanoparticles has been proposed by combining Flory-Huggins free energy of isotropic mixing and Landau free energy. The impact of nanoparticles on the RII -RI -RV phase transitions and their transition temperatures is discussed by means of phenomenological theory. The possibility of the tricritical behavior of the RI -RV phase transition in the mixtures of alkanes and nanoparticles is discussed. The theoretical predictions are in good qualitative agreement with available experimental results.

    Optical Diffraction Tomography (ODT), as a novel 3D imaging technique, can obtain a 3D refractive index (RI) distribution to reveal the important optical properties of transparent samples. According to the theory of ODT, an optical diffraction tomography setup is built based on the Mach-Zehnder interferometer. The propagation direction of object beam is controlled by a 2D translation stage, and 121 holograms based on different illumination angles are recorded by a Charge-coupled Device (CCD). In order to prove the validity and accuracy of the ODT, the 3D RI profile of microsphere with a known RI is firstly measured. An iterative constraint algorithm is employed to improve the imaging accuracy effectively. The 3D morphology and average RI of the microsphere are consistent with that of the actual situation, and the RI error is less than 0.0033. Then, an optical element fabricated by laser with a non-uniform RI is taken as the sample. Its 3D RI profile is obtained by the optical diffraction tomography system.

    The age-thrombus burden-index of microcirculatory resistance (ATI) score is a diagnostic tool able to predict suboptimal myocardial reperfusion before stenting, in patients with ST-elevation myocardial infarction (STEMI). We aimed to validate the ATI score against cardiac magnetic resonance imaging (cMRI). The ATI score was calculated prospectively in 80 STEMI patients. cMRI was performed within 48 hours in all patients and in 50 patients at six-month follow-up to assess the extent of infarct size (IS%) and microvascular obstruction (MVO%). The ATI score was calculated using age (>50=1 point), pre-stenting index of microcirculatory resistance (IMR) (>40 and <100=1 point; ≥100=2 points) and angiographic thrombus score (4=1 point; 5=3 points). ATI score was closely related to final IS% (ATI.

    The cleavage of DNA by restriction endonuclease EcoRI is catalyzed by metal ions such as Mg^2+. However, Cu^2+ does not catalyze the cleavage of DNA by EcoRI. In order to understand the functional difference between Cu^2+ and Mg^2+, coordination of Cu^2+ in the EcoRI--DNA complex was clarified by ESR and MD simulation. There are two Cu^2+ components in the specific EcoRI-DNA complex. Each component has one N atom from histidine imidazole and one oxygen atom from the phosphate backbone of DNA coordinate to Cu^2+ based on the ESR experimental results. MD simulation further confirmed that the Nδ atom of His114 imidazole and one oxygen atom from the phosphate backbone of DNA coordinate to Cu^2+. Difference in the coordination of Cu^2+ and Mg^2+ explains their different functional behaviors.

    This study evaluated the economic value addition of nuclear power generation technology and radio-isotope(RI) technology quantitatively by using modified Input-Output table. For the nuclear power generation technology, the economic effect of both power plant construction and operation was evaluated. On the other hand, the economic effect of the RI utilization on the national economy was evaluated for RI technology. Firstly, the total economic value addition from nuclear power generation(both construction and operation) was estimated as 1.4% of Gross Domestic Product(GDP) in 2000. Among them, 1.2% was from nuclear power plant operation and the rest was from construction. On the other hand, the economic value addition from RI technology has continuously increased. Its share of GDP increased from 0.30% in 1980 to 0.58 in 2000

    At present, measurement of wet density and water content by radio isotope (RI method) is used for filling management. It is supposed for filling in road construction that putting-out thickness of banking material reaches nearly 1m in the future rapid construction, however, use of RI method is difficult because of inserting and installing of a radiation source rod, large measuring apparatus, and the legal regulation on radioactivity intensity. Application of resistivity measurement was thus considered. Since resistivity has the same parameter as compaction curve, and monotonously decreases with an increase in water content by volume, it is applicable as construction management index. The management reference of resistivity (Rm) is set by plotting of a compaction curve and corresponding resistivity curve, determination of the reference resistivity (Ro) corresponding to a maximum dry density and optimum water content ratio, and setting of the allowance to Ro according to soil or application. It was clarified that Rm is applicable as set for every filling material. 1 ref., 10 figs., 2 tabs.

    Maintenance and other personnel related errors are a major cause of reactor trips in some U.S. plants. Software called RiTSE and KCGE, that can operate on a mini-computer work station, has been developed to dramatically reduce trips caused by clearance coordination problems. Such problems arise because of the enormous number of components that interrelate in ways that cannot always be anticipated during plant operation. Concurrent maintenance, test, surveillance and other operations activities contribute to the unanticipated interactions. RiTSE allows the appropriate plant personnel (i.e., those responsible for authorizing work during start-up and operation) to predict if their next authorizations would cause a reactor trip. With KCGE, RiTSE can warn these personnel of a condition of significantly reduced margin to trip. RiTSE also aids post-trip cause analysis by pointing out those components that could have contributed to the trip. It is believable that use of RiTSE is a quicker and more reliable way to authorize work during operation than reliance on memory and drawings. The software provides maximum benefit when used in conjunction with a configuration management program that assures accurate plant presentation and accurate updating of component status during operation. Application of RiTSE and KCGE to a client's PWR demonstrated part of their potential benefits. (Nogami, K.)

  3. Method and apparatus for observing the RI distribution image of a scintillation camera

    1970-01-01

    The present invention relates to a method and apparatus for identifying the positions of the RI distribution image in a human body by superimposing the roentgenogram of the body over the RI distribution image developed on a cathode ray tube. The apparatus comprises a display cathode ray tube, a plate, and a roentgenogram transparency. The RI distribution image is developed on a circular area of about 13 cm in diameter at the center of the display surface of the tube. The RI distribution image and the roentgenogram transparency have two markers to allow superposition of the corresponding positions on the human body. However, observation of the roentgenogram transparency is difficult in areas other than the circular area where the background is comparatively bright. For this reason, a white plate or an illuminated plate is provided between the cathode ray tube surface and the transparency to brighten the background in these areas. The plate has a circular opening of a diameter corresponding to that of the RI image. Thus the present apparatus makes it possible to easily observe the superposed image of the roentgenogram and the RI distribution image. (R. Masui)

    This paper investigates a refractive index (RI) sensor based on a macrobending micro-plastic optical fiber (m-POF), which is used as a sensitive probe. The m-POFs are fabricated from commercial POFs using a heating and pulling method. The m-POFs have diameters of approximately 20-40 μm and act as multimode fibers at visible wavelengths. The macrobending structure of the m-POFs is simulated and optimized using the ray tracing method. The RI sensitivity and the range of RI measurements are affected by the structure parameter R/ρ, which is the ratio of the radius of curvature of the macrobending fiber to the radius of the fiber itself. A linear RI sensing response is obtained when R/ρ=20 and the sensitivity reaches 500%/RIU. The experimental results coincide well with the simulation results.

    To determine whether the refractive index (RI) of a soft contact lens can be evaluated using refractometry while the lens remains on the eye and to compare this with more traditional ex vivo RI measurements. A slitlamp apparatus was modified to incorporate a customized Atago hand refractometer. With a double-masked study design, nine adapted symptomatic soft contact lens wearers wore a contact lens in each eye (lotrafilcon B and etafilcon A) in a randomized order. In vivo RI was determined from the relative Brix scale measurements immediately after lens insertion and after 1 and 10 hr of lens wear. Ex vivo refractometry was performed after 10 hr of lens wear for comparison. Means +/- standard errors of the means are reported. In vivo RI values at baseline were 1.422 +/- 0.0004 (lotrafilcon B) and 1.405 +/- 0.0021 (etafilcon A); after 1 hr of lens wear, values were 1.423 +/- 0.0006 and 1.408 +/- 0.0007, respectively; and after 10 hr of lens wear, values were 1.424 +/- 0.0004 and 1.411 +/- 0.0010, respectively. Ex vivo RI values at the end of the 10 hr wearing period were 1.424 +/- 0.0003 (lotrafilcon B) and 1.412 +/- 0.0017 (etafilcon A). The change in in vivo RI across the day was statistically significant for the etafilcon A lens (repeated-measures analysis of variance, P0.05). This novel adaptation of refractometry was able to measure the RI of soft contact lenses during wear (without lens removal). End of day RI measurements using in vivo and ex vivo refractometry were comparable with each other. Future work is required to determine whether this in vivo method can improve our understanding of the relationships between soft contact lens RI, hydration, on-eye lens performance, and symptomology.

    The specific pathogenesis of increased vulnerability to cocaine-induced paranoia/psychosis is unknown. Weight loss has been long observed in patients abusing stimulants (including cocaine and the amphetamines). In the current study, we compared Body Mass Index (calculated as weight in kilograms divided by the square of height in meters) in Cocaine-Induced Psychosis cases, referred to as "Cocaine-Induced Psychosis-prone" (n=40) and non-Cocaine-Induced Psychosis cases, referred to as "Cocaine-Induced Psychosis-resistant" (n=29) consecutively admitted to a research substance abuse unit to determine whether Body Mass Index is associated with Cocaine-Induced Psychosis. Height and weight were measured and Body Mass Index calculated by a licensed nutritionist using a standardized protocol. Cocaine-induced psychosis and cocaine use patterns were assessed using the Cocaine Experience Questionnaire. Body Mass Index in the Cocaine-Induced Psychosis-prone patients was significantly lower than in the Cocaine-Induced Psychosis-resistant patients (i.e., 23.1 kg/m2 +/-2.5 vs. 25.4 kg/m2 +/-3.5 (P=.003), respectively). Percentage of Ideal Body Weight also differed significantly between the two groups. The data suggest that lower Body Mass Index may be associated with increasing proneness to developing psychotic symptoms in the context of crack cocaine use or that higher Body Mass Index might be associated with some protection against Cocaine-Induced Psychosis in the context of similar use patterns. In the Discussion the authors speculate as to why Cocaine-Induced Psychosis is more commonly observed in the patient population with lower Body Mass Index and lower percentage of Ideal Body Weight. They evoke possible involvement of cocaine's influence on the anorexigenic cytokine Tumor Necrosis Factor, Cocaine-and-Amphetamine-Regulated Transcript, or suppression of the appetite stimulating Neuropeptide Y, or cocaine-induced deficits in nicotinic cholinergic neural-transmission, all of

    IgG4-related disease (IgG4-RD) can cause fibro-inflammatory lesions in nearly any organ, leading to organ dysfunction and failure. The IgG4-RD Responder Index (RI) was developed to help investigators assess the efficacy of treatment in a structured manner. We sought to validate the RI in a multi-national investigation. The RI guides investigators through assessments of disease activity and damage in 25 domains, incorporating higher weights for disease manifestations that require treatment urgently or that worsen despite treatment. After a training exercise, investigators reviewed 12 written IgG4-RD vignettes (mean length: 279 words, range: 76-511 words) based upon real patients. Investigators calculated both an RI score as well as a physician global assessment (PGA) for each vignette. Three investigators used the RI on fifteen patients followed over serial visits after treatment. We assessed inter- and intra-rater reliability, precision, validity, and responsiveness. Twenty-six physician-investigators included representatives from 6 specialties and 9 countries. The inter-rater and intra-rater reliabilities of the RI were strong (0.88 and 0.69, respectively) and superior to those of the PGA. Correlations (construct validity) between the RI and PGA were high (Spearman's r=0.9, P<0.0001). The RI was sensitive to change (discriminant validity). Following treatment, there was significant improvement in the RI (mean change 10.5 (95% CI 5.4-12), P<0.001) which correlated with the change in the PGA. Urgent disease and damage were captured effectively. In this international, multi-specialty study, we found that the RI is a valid, and reliable disease activity assessment tool that can be used to measure response to therapy.

    To measure the refractive index (RI) of the human corneal stroma in vivo using an objective Abbé refractometer (VCH-1) and to determine if RI of the stroma is related to age. The VCH-1 was calibrated against a standard subjective Abbé refractometer using 7 randomly selected turbid semiliquid media. VCH-1 was used to measure RI at the central midstroma immediately after lifting the flap in neophyte patients preselected for laser-assisted in situ keratomileusis. Surgical procedures continued as preplanned after measuring the RI; in binocular cases, measurements were taken from the right eye only. Flaps were created using a mechanical microkeratome. The VCH-1 was capable of measuring the RIs of all 7 turbid semiliquid media. The average RMS difference between RI estimates according to the VCH-1 and standard subjective Abbé refractometer was 0.003. The mean RI (± SD) of the stroma was 1.369 (± 0.008; range, 1.356-1.390), and the mean age (± SD) of the subjects was 33.7 years (± 8.86; range, 18-56 years). A significant linear correlation was found between age and RI. Least squares regression lines equating RI with age (x, years) was of the form: RI = 1.35711 + 0.00034x (r = +0.383, n = 36, P = 0.011). RI of the stroma in vivo has a tendency to be increased in older patients when the stroma is resected using a mechanical microkeratome.

    The aims of the present study were: (a) to investigate the prevalence and the enumeration of Listeria monocytogenes in 200 samples of ready to eat (RTE) foods of animal and vegetal origin collected from different outlets and processing plants in Sardinia; (b) to characterize the isolates by phenotypical and molecular methods; (c) to analyze a subset of 42 L. monocytogenes by automated EcoRI ribotyping in order to predict the strain's potential virulence for humans. The strains were isolated from: smoked fish products, cooked marinated products, meat products and pre-packaged mixed vegetable salads. Of the samples tested, 22% were positive for Listeria spp. The prevalence of L. monocytogenes was 9.5%, while the level of L. monocytogenes in the positive samples was 93%), belonging to 17 different DuPont Identification Library Codes (DUP-IDs) clones. The Simpson's numerical index of discrimination was 0.911. Cluster analysis pointed out a high similarity among strains isolated from meat, fish, and vegetables of different origin. These results confirmed the existence of a widespread population of L. monocytogenes, characterized by highly related strains existing in different geographical areas. 65% of these strains belonged to lineage II (serotypes 1/2a and 1/2c), subtypes known to be associated with sporadic human listeriosis outbreaks. The remaining 35% of the isolates (serotypes 1/2b, 3b and 4b) were allocated to lineage I and belong to distinct clonal groups (DUP-ID 1038 and 1042), which again have been associated with several outbreaks of human listeriosis. Neither atypical profiles nor lineage III strains were found. EcoRI ribotyping was confirmed as a rapid and reliable method for L. monocytogenes typing, providing useful data for epidemiologic and clonality surveys of L. monocytogenes strains isolated from RTE foods.

    Faecal incontinence is a physically, psychologically and socially disabling condition. NICE guidance (2007) recommends surgical intervention, including sacral nerve stimulation (SNS), after failed conservative therapies. The FENIX magnetic sphincter augmentation (MSA) device is a novel continence device consisting of a flexible band of interlinked titanium beads with magnetic cores that is placed around the anal canal to augment anal sphincter tone through passive attraction of the beads. Preliminary studies suggest the FENIX MSA is safe, but efficacy data is limited. Rigorous evaluation is required prior to widespread adoption. The SaFaRI trial is a National Institute of Health Research (NIHR) Health Technology Assessment (HTA)-funded UK multi-site, parallel group, randomised controlled, unblinded trial that will investigate the use of the FENIX MSA, as compared to SNS, for adult faecal incontinence resistant to conservative management. Twenty sites across the UK, experienced in the treatment of faecal incontinence, will recruit 350 patients randomised equally to receive either SNS or FENIX MSA. Participants will be followed-up at 2 weeks post-surgery and at 6, 12 and 18 months post-randomisation. The primary endpoint is success, as defined by device in use and ≥50 % improvement in the Cleveland Clinic Incontinence Score (CCIS) at 18 months post-randomisation. Secondary endpoints include complications, quality of life and cost effectiveness. SaFaRI will rigorously evaluate a new technology for faecal incontinence, the FENIX™ MSA, allowing its safe and controlled introduction into current clinical practice. These results will inform the future surgical management of adult faecal incontinence.

  14. Endogenous IL-1 in cognitive function and anxiety: a study in IL-1RI-/- mice.

    Carol L Murray

    Full Text Available Interleukin-1 (IL-1 is a key pro-inflammatory cytokine, produced predominantly by peripheral immune cells but also by glia and some neuronal populations within the brain. Its signalling is mediated via the binding of IL-1α or IL-1β to the interleukin-1 type one receptor (IL-1RI. IL-1 plays a key role in inflammation-induced sickness behaviour, resulting in depressed locomotor activity, decreased exploration, reduced food and water intake and acute cognitive deficits. Conversely, IL-1 has also been suggested to facilitate hippocampal-dependent learning and memory: IL-1RI(-/- mice have been reported to show deficits on tasks of visuospatial learning and memory. We sought to investigate whether there is a generalised hippocampal deficit in IL-1RI(-/- animals. Therefore, in the current study we compared wildtype (WT mice to IL-1RI(-/- mice using a variety of hippocampal-dependent learning and memory tasks, as well as tests of anxiety and locomotor activity. We found no difference in performance of the IL-1RI(-/- mice compared to WT mice in a T-maze working memory task. In addition, the IL-1RI(-/- mice showed normal learning in various spatial reference memory tasks including the Y-maze and Morris mater maze, although there was a subtle deficit in choice behaviour in a spatial discrimination, beacon watermaze task. IL-1RI(-/- mice also showed normal memory for visuospatial context in the contextual fear conditioning paradigm. In the open field, IL-1RI(-/- mice showed a significant increase in distance travelled and rearing behaviour compared to the WT mice and in the elevated plus-maze spent more time in the open arms than did the WT animals. The data suggest that, contrary to prior studies, IL-1RI(-/- mice are not robustly impaired on hippocampal-dependent memory and learning but do display open field hyperactivity and decreased anxiety compared to WT mice. The results argue for a careful evaluation of the roles of endogenous IL-1 in hippocampal

    Besides its crucial role in type I hypersensitivity reactions, IgE is involved in anti-parasite immunity. This role has been clearly demonstrated in both human and rat schistosomiasis, but remains controversial in the mouse. Since the cellular distribution of the high affinity IgE receptor, Fc epsilon RI, differs in humans and mice, it might explain the differences in effector function of IgE between the two species. In humans, eosinophils and macrophages induce IgE-dependent cytotoxicity toward Schistosoma mansoni larvae, which involves Fc epsilon RI in the case of eosinophils. In the present study, we have investigated the expression and function of Fc epsilon RI in rat eosinophils and macrophages. We demonstrate, by flow cytometry, fluorescence microscopy, and western blot analysis, that in rats, as in humans, a functional alpha gamma 2 trimeric Fc epsilon RI is expressed on eosinophils and macrophages. We also show that these two cell types can induce IgE-mediated, Fc epsilon RI-dependent cellular cytotoxicity toward schistosomula. These results thus provide a molecular basis for the differences observed between rat and mouse regarding IgE-mediated anti-parasite immunity.

  16. Emdogain-regulated gene expression in palatal fibroblasts requires TGF-βRI kinase signaling.

    Directory of Open Access Journals (Sweden)

    Alexandra Stähli

    Full Text Available Genome-wide microarrays have suggested that Emdogain regulates TGF-β target genes in gingival and palatal fibroblasts. However, definitive support for this contention and the extent to which TGF-β signaling contributes to the effects of Emdogain has remained elusive. We therefore studied the role of the TGF-β receptor I (TGF-βRI kinase to mediate the effect of Emdogain on palatal fibroblasts. Palatal fibroblasts were exposed to Emdogain with and without the inhibitor for TGF-βRI kinase, SB431542. Emdogain caused 39 coding genes to be differentially expressed in palatal fibroblasts by microarray analysis (p10-fold. Importantly, in the presence of the TGF-βRI kinase inhibitor SB431542, Emdogain failed to cause any significant changes in gene expression. Consistent with this mechanism, three independent TGF-βRI kinase inhibitors and a TGF-β neutralizing antibody abrogated the increased expression of IL-11, a selected Emdogain target gene. The MAPK inhibitors SB203580 and U0126 lowered the impact of Emdogain on IL-11 expression. The data support that TGF-βRI kinase activity is necessary to mediate the effects of Emdogain on gene expression in vitro.

    2009-03-01

    Pulsed electron spin resonance (ESR) was used to probe the binding specificity of EcoRI, a restriction endonuclease. Using site-directed spin labeling, a nitroxide side chain was incorporated into the protein, enabling the use of ESR to study structural details of EcoRI. Distance measurements were performed on EcoRI mutants when bound to varying sequences of DNA using the Double Electron-Electron Resonance experiment. These distances demonstrated that the average structure in the arm regions of EcoRI, thought to play a major role in binding specificity, is the same when the protein binds to different sequences of DNA. Also, it was determined that the arms exhibit higher flexibility when bound to sequences other than the specific sequence due to the larger distance distributions acquired from these spin labeled complexes. Molecular dynamics (MD) simulations were performed on the spin-label-modified specific EcoRI-DNA crystal structure to model the average nitroxide orientation. The distance distributions from MD were found to be narrower than experiment, indicating the need for a more rigorous sampling of the nitroxide conformers in silico.

    The GGCC-specific restriction endonuclease BspRI is one of the few Type IIP restriction endonucleases, which were suggested to be a monomer. Amino acid sequence information obtained by Edman sequencing and mass spectrometry analysis was used to clone the gene encoding BspRI. The bspRIR gene is located adjacently to the gene of the cognate modification methyltransferase and encodes a 304 aa protein. Expression of the bspRIR gene in Escherichia coli was dependent on the replacement of the native TTG initiation codon with an ATG codon, explaining previous failures in cloning the gene using functional selection. A plasmid containing a single BspRI recognition site was used to analyze kinetically nicking and second-strand cleavage under steady-state conditions. Cleavage of the supercoiled plasmid went through a relaxed intermediate indicating sequential hydrolysis of the two strands. Results of the kinetic analysis of the first- and second-strand cleavage are consistent with cutting the double-stranded substrate site in two independent binding events. A database search identified eight putative restriction-modification systems in which the predicted endonucleases as well as the methyltransferases share high sequence similarity with the corresponding protein of the BspRI system. BspRI and the related putative restriction endonucleases belong to the PD-(D/E)XK nuclease superfamily.

    Full Text Available Recently, data privacy in wireless sensor networks (WSNs has been paid increased attention. The characteristics of WSNs determine that users’ queries are mainly aggregation queries. In this paper, the problem of processing aggregation queries in WSNs with data privacy preservation is investigated. A Ring-based Privacy-Preserving Aggregation Scheme (RiPPAS is proposed. RiPPAS adopts ring structure to perform aggregation. It uses pseudonym mechanism for anonymous communication and uses homomorphic encryption technique to add noise to the data easily to be disclosed. RiPPAS can handle both s u m ( queries and m i n ( / m a x ( queries, while the existing privacy-preserving aggregation methods can only deal with s u m ( queries.

    The aim of this study was to ascertain the utility of echo-Doppler in the analysis of the low resistance thyroid vascularization in diffuse toxic goiter (DTG), and the effectiveness of Lugol's solution (iodine-iodide solution) in patients undergoing thyroidectomy. Twenty-five patients with diffuse toxic goiter were evaluated and compared with 19 normal subjects. Patients were treated with increasing doses of Lugol's solution 2% for 7 days until a total dose of 75 mg of iodine was given. Echo-Doppler was performed on the last day of treatment, 12 hours before operation. Mean basal Doppler Resistance Index (RI) of intrathyroid arterial flow was significantly lower in patients with DTG compared with normal controls (0.4718 +/- 0.0625 versus 0.55 +/- 0.05, range: 0.472 to 0.643; p = 0.008). Moreover, the RI was significantly increased in patients with DTG after Lugol's solution (+16.46 +/- 10.22%, range: -2.59 to +39.97; pLugol's solution therapy induces normalization of those changes for safer thyroidectomy.

Its focus lies on a collection of Liiv’s poetry Snow Drifts, I Sing: Selected Poems (Lumi tuiskab, mina laulan: Valik luulet, 2013 compiled by Talvet. I shall compare this book with the most extensive volume of Liiv’s poetry of the previous century With and Without You (Sinuga ja sinuta, 1989 edited by Aarne Vinkel, which has had a major role in the shaping of the norms that serve as a basis for understanding Liiv’s work in recent times. The article observes how these volumes mediate Liiv’s poetry and the way Talvet transposes its earlier publishing standards. More particularly, I will analyse the poetry collection edited by Talvet from five perspectives: I will map the new texts and text fragments included in the work, discuss Talvet’s corrections and highlight the omitted fragments and full texts. Such specific treatment can be narrowed down to three broader topics: what new additions Talvet makes to the known textual body of Liiv’s poems (new texts; what changes he makes to previously published poems (textual additions, corrections and omissions; what he has left out (omitted texts.

His numerous translations of poetry and poetical fiction from the Romance languages and, to a lesser extent, from English, reflect his views on world poetry. Those views are also expressed in his theoretical writings from the years of 1977 to 2015. Having studied English literature as the main subject at the University of Tartu, he early developed an interest in Spanish, in other Iberian languages, and in the Iberoamerican literatures. His translations from that area include works from medieval and early modern literature as well as notable literary achievements from the 20th century and the contemporary era. Talvet’s interpretations of Federico García Lorca and the “Latin American boom” authors are supported by profound insights into the philosophy, aesthetics, and poetics of the 17th century Spanish Baroque literature, known as the literary Golden Age of Spain. The influence which Talvet’s activities have exerted has widened the horizons of Estonia’s literary culture: while in the early 20th century, the previous German, Russian and Finnish leanings were supplemented by orientations to, and translations from, French and Italian literatures, Talvet has helped to enrich the Estonian literary landscape

    This paper analyses the historical and epistemological work of the French psychiatrist Georges Lantéri-Laura (1930-2004) within the context of the French 'tradition' of history and philosophy of sciences, with special reference to Georges Canguilhem and Michel Foucault. After an introduction devoted to a critical survey of the most recent works on the history and historiography of psychiatry in French, the paper outlines Lantéri-Laura's approach by focusing especially on the role played by the methodological concept of 'semiology' as regards the relation between medicine and psychiatry. The last part of the paper draws attention to the relation between the history and philosophy of psychiatry in light of Lantéri-Laura's 'critical epistemology'.

    Apoptosis, or the programmed cell death, is the generally normal death of a cell in living organisms. Inappropriate apoptosis (either too little or too much) is a factor in many human disease including neurodegenerative diseases, autoimmune disorders and many types of cancer. Therefore, it is one of the most challenging and widely studied topics currently. Development of RI-based real-time display technology of apoptosis can be provided invaluable analysis data for diagnosis and treatment of various diseases. In this study, bifunctional chelator (BFC) for Tc-99m tricarbonyl was synthesized for ML-10 derivative radiolabeling. The formation of complexation of apoptotic cells was developed by combining the ML-10 moiety with the BFC for {sup 99m}Tc-tricarbonyl precursor. The results of this project will be utilized for the development of RI-Biomics Center-based Total Analysis System (TAS) through the optimization of equipment in the RI-Biomics Center.

    2011-06-01

    Mast cells express the high-affinity receptor for IgE (FcεRI) and are key players in type I hypersensitivity reactions. They are critically involved in the development of allergic rhinitis, allergic asthma and systemic anaphylaxis, however, they also regulate normal physiological processes that link innate and adaptive immune responses. Thus, their activation has to be tightly controlled. One group of signaling molecules that are activated upon FcεRI stimulation is formed by Tec family kinases, and three members of this kinase family (Btk, Itk and Tec) are expressed in mast cells. Many studies have revealed important functions of Tec kinases in signaling pathways downstream of the antigen receptors in lymphocytes. This review summarizes the current knowledge about the function of Tec family kinases in FcεRI-mediated signaling pathways in mast cell. © 2011 The Authors Journal compilation © 2011 FEBS.

    1992-12-01

    A Schedule Optimization Study (SOS) of the US Department of Energy (DOE) Hanford Site Remedial Investigation/Feasibility Study (RI/FS) Program was conducted by an independent team of professionals from other federal agencies and the private sector experienced in environmental restoration. This team spent two weeks at Hanford in September 1992 examining the reasons for the lengthy RI/FS process at Hanford and developing recommendations to expedite the process. The need for the study arose out of a schedule dispute regarding the submission of the 1100-EM-1 Operable Unit RI/FS Work Plan. This report documents the study called for in the August 29, 1991, Dispute Resolution Committee Decision Statement. Battelle`s Environmental Management Operations (EMO) coordinated the effort for DOE`s Richland Field Office (RL).

    Our aim was to determine whether 12 weeks' aerobic Nordic walking (NW) or resistance exercise training (RT) without diet-induced weight loss could decrease oxidative stress and atherogenic index of plasma (AIP), prevalence of metabolic syndrome (MetS) and MetS score in middle-aged men with impaired glucose regulation (IGR) (n=144. 54.5 ± 6.5 years). In addition, we compared effects of intervention between overweight and obese subgroups. Prevalence of MetS and AIP index decreased only in NW group and MetS score in both NW and RT groups but not in control group. The changes in AIP index correlated inversely with changes in plasma antioxidant capacity. The change in AIP index remained a significant independent predictor of the changes in MetS score after the model was adjusted for age, BMI and volume of exercise (MET h/week) in NW group. There were no changes in the other measured markers of oxidative stress and related cytokines (e.g. osteopontin and osteoprotegerin) in any of the groups. Nordic walking decreased prevalence of MetS and MetS score. Improved lipid profile remained a predictor of decreased MetS score only in NW group and it seems that Nordic walking has more beneficial effects on cardiovascular disease risks than RT training.

In this study, the objective was to discuss the measures and anthropometric indices that have been associated with IR. A bibliographic review was done, based on Scielo, Science Direct and Pubmed. Among these studies, waist and sagittal abdominal diameter presented better predictive capacity for IR, with more consistent results. The waist-to-thigh, waist-to-size, neck-to-thigh ratios, the conicity and the sagittal index have showed positive results; nevertheless, more studies are necessary to consolidate them as predictors to IR. The obtained results, with the use of body mass index and of the waist-to-hip ratio, were inconsistent. In the Brazilian population, the realization of studies evaluating the performance of these indicators in predicting IR is suggested, since the results of the studies conducted in other populations are not always applicable to ours, due to ethnical differences resulting from the great miscegenation in the country.

    Full Text Available OBJECTIVE: Increments in red blood cell count (RBC, hemoglobin (Hb and hematocrit (Ht levels are reportedly associated with higher insulin resistance (IR. Obesity may cause IR, but underlying factors remain incompletely defined, and interactions between obesity, hematological parameters and IR are incompletely understood. We therefore determined whether: 1 BMI and obesity per se are independently associated with higher RBC, hemoglobin and hematocrit; 2 hematological parameters independently predict insulin resistance in obese individuals. DESIGN AND METHODS: We investigated the associations between BMI, hematological parameters and insulin resistance as reflected by homeostasis model assessment (HOMA in a general population cohort from the North-East Italy MoMa epidemiological study (M/F = 865/971, age = 49 ± 1. RESULTS: In all subjects, age-, sex- and smoking-adjusted hematological parameters were positively associated with BMI in linear regression (P<0.05, but not after adjustment for HOMA or waist circumference (WC and potential metabolic confounders. No associations were found between hematological parameters and BMI in lean, overweight or obese subgroups. Associations between hematological parameters and HOMA were conversely independent of BMI in all subjects and in lean and overweight subgroups (P<0.01, but not in obese subjects alone. CONCLUSIONS: In a North-East Italy general population cohort, obesity per se is not independently associated with altered RBC, Hb and Ht, and the association between BMI and hematological parameters is mediated by their associations with abdominal fat and insulin resistance markers. High hematological parameters could contribute to identify insulin resistance in non-obese individual, but they do not appear to be reliable insulin resistance biomarkers in obese subjects.

    A bidirectional relationship exists between diabetes and periodontitis. In the present clinical trial, we evaluated the effects of non-surgical periodontal therapy (NSPT) on insulin resistance in patients with type II diabetes mellitus (DM) and chronic periodontitis. Forty chronic periodontitis patients with type II DM were selected and equally allocated to case and control groups. All patients were assessed for periodontal parameters and systemic parameters. The case group received NSPT, and both groups were re-evaluated after 3 months. All periodontal parameters were found to be significantly improved in the case group compared to the control group 3 months after NSPT. The mean differences in systemic parameters, such as fasting serum C-peptide, Homeostasis Assessment (HOMA) Index-insulin resistance, and HOMA-insulin sensitivity, from baseline to 3 months for the case group were 0.544 ± 0.73, 0.54 ± 0.63, and -25.44 ± 36.81, respectively; for the control group, they were significant at -1.66 ± 1.89, -1.48 ± 1.86, and 31.42 ± 38.82 respectively (P periodontal inflammation could affect glycemic control and insulin resistance. Effective periodontal therapy reduced insulin resistance and improved periodontal health status and insulin sensitivity in patients with type II DM and chronic periodontitis. © 2016 John Wiley & Sons Australia, Ltd.

    The present study was designed to assess the impact of intensive and repetitive nutrition education and lifestyle interventions on insulin resistance, β-cell function, disposition index (DI), and subclinical inflammation in Asian Indian adolescents (15-17 years) residing in North India. In this prospective study, two matched schools were randomly allocated to the intervention (n = 56; 31 boys and 25 girls) or control group (n = 50; 30 boys and 20 girls). The intervention consisted of seven components: (1) Dissemination of health-related information through lectures and focused group discussions, (2) planning of activities such as quizzes, (3) individual counseling of students, (4) promotion of physical activity, (5) change in the canteen menu to healthier alternatives, (6) conducting health camps involving parents and teachers, and (7) training of student volunteers for sustainability of the program in school. Impact of intervention was studied on surrogate markers of insulin resistance, β-cell function, disposition index, and subclinical inflammation. At 6 months follow-up, significantly higher (P = 0.037) mean value of homeostasis model assessment denoting β-cell function (HOMA-βCF) was seen in the intervention group compared to the control group, whereas high sensitivity C-reactive protein (hs-CRP) was significantly lowered (P < 0.001). The increase (30.3 ± 73.4; P < 0.037) observed in the DI in adolescents in the intervention group was significantly higher compared to the control group. The Pearson's coefficient of correlation in the intervention group showed that the Δ-decrease in mean waist circumference was significantly correlated (r = 0.267, P < 0.05) with Δ-decrease in homeostasis model assessment of insulin resistance (HOMA-IR). The intervention model developed by us could be used for amelioration of insulin resistance with potential of preventing type 2 diabetes mellitus in Asian Indian adolescents.

    Genome-wide microarrays have suggested that Emdogain regulates TGF-β target genes in gingival and palatal fibroblasts. However, definitive support for this contention and the extent to which TGF-β signaling contributes to the effects of Emdogain has remained elusive. We therefore studied the role of the TGF-β receptor I (TGF-βRI) kinase to mediate the effect of Emdogain on palatal fibroblasts. Palatal fibroblasts were exposed to Emdogain with and without the inhibitor for TGF-βRI kinase, SB43...

    The expression of almost all genes in animals is subject to post-transcriptional regulation by RNA binding proteins (RBPs) and microRNAs (miRNAs). The interactions between both RBPs and miRNAs with mRNA can be mapped on a whole-transcriptome level using experimental and computational techniques established in the past years. The combined action of RBPs and miRNAs is thought to form a post-transcriptional regulatory code. Here we present doRiNA 2.0, available at http://dorina.mdc-berlin.de. In this highly improved new version, we have completely reworked the user interface and expanded the database to improve the usability of the website. Taking into account user feedback over the past years, the input forms for both the simple and the combinatorial search function have been streamlined and combined into a single web page that will also display the search results. Especially, custom uploads is one of the key new features in doRiNA 2.0. To enable the inclusion of doRiNA into third-party analysis pipelines, all operations are accessible via a REST API. Alternatively, local installations can be queried using a Python API. Both the web application and the APIs are available under an OSI-approved Open Source license that allows research and commercial access and re-use. © The Author(s) 2014.

  9. Measurement of refractive index by nanoparticle tracking analysis reveals heterogeneity in extracellular vesicles

    Directory of Open Access Journals (Sweden)

    Chris Gardiner

    2014-11-01

    Full Text Available Introduction: Optical techniques are routinely used to size and count extracellular vesicles (EV. For comparison of data from different methods and laboratories, suitable calibrators are essential. A suitable calibrator must have a refractive index (RI as close to that of EV as possible but the RI of EV is currently unknown. To measure EV, RI requires accurate knowledge of size and light scattering. These are difficult to measure as most EVs cannot be resolved by light microscopy and their diameter is smaller than the wavelength of visible light. However, nanoparticle tracking analysis (NTA provides both size and relative light scattering intensity (rLSI values. We therefore sought to determine whether it was possible to use NTA to measure the RI of individual EVs. Methods: NTA was used to measure the rLSI and size of polystyrene and silica microspheres of known size and RI (1.470 and 1.633, respectively and of EV isolated from a wide range of cells. We developed software, based on Mie scattering code, to calculate particle RI from the rLSI data. This modelled theoretical scattering intensities for polystyrene and silica microspheres of known size (100 and 200 nm and RI. The model was verified using data from the polystyrene and silica microspheres. Size and rLSI data for each vesicle were processed by the software to generate RI values. Results: The following modal RI measurements were obtained: fresh urinary EV 1.374, lyophilised urinary EV 1.367, neuroblastoma EV 1.393, blood EV 1.398, EV from activated platelets 1.390, small placental EV 1.364–1.375 and 1.398–1.414 for large placental EV (>200 nm. Large placental EV had a significantly higher RI than small placental EV (p1.40 were observed for some large (>200 nm microvesicles. Conclusion: This method for measuring EV RI will be useful for developing appropriate calibrators for EV measurement.

  10. The validity of the risk index for comparing the accident risk associated with different work schedules.

    2013-01-01

    Although it is known that there is an association between working hours and occupational accidents, there are only few tools which allow for an assessment of the risk associated with different working time arrangements, none of them validated yet by independent samples. Promising tools like the risk index (RI), assessed via the fatigue and risk index calculator, thus need to be validated. Since analyses on the validity of the RI based on individual data found only moderate associations between the RI and the actual accident risk, the question arises, whether a validation based on grouped data yields more promising results. Thus, the validity of the RI was re-examined, using aggregated data, i.e. pooling several individuals into groups of respondents according to their RI-score and performing calculations on the group level in order to control for individual and random variation. The study sample (n=337) was derived from an Internet survey on working hours and health, which contained information on working hours over four weeks and on the occurrence of an occupational accident during the last 12 months. Two models of aggregation were used: a distribution based and a criterion based classification, resulting in four RI groups each. Accident rates for each group were calculated and compared via χ(2)-analyses and fitting trends to the data. Results show, for both models of aggregation, that the accident rate increased exponentially with an increasing RI. Risk was 3.7 times (distribution based aggregation) and 6.5 times (criterion based aggregation) higher in the highest compared to the lowest RI-groups. The exponential trend explained 92% (distribution based aggregation) and 98% (criterion based aggregation) of the variance, respectively. Analyses for homogeneous subgroups (e.g., service sector, and workers with high workload) showed similar trends. Thus the analyses based on aggregated data indicated a considerable and consistently higher validity of the RI than the

    2011-05-01

    This work presents an application of radio-frequency plasma-assisted chemical-vapor-deposited (RF PACVD) diamondlike carbon (DLC) nano-coatings for effective tuning of the refractive-index (RI) sensitivity of long-period gratings (LPGs) over a wide range (nD from 1 to 1.47). The technique allows for an efficient deposition of good quality nanofilms as required for optical sensors. The thin overlay effectively changes the distribution of the cladding modes and thus tunes the device's RI sensitivity. We correlated the optical properties of the DLC films with the RI sensitivity of the LPGs. For the developed deposition process parameters, the tuning can be realized simply by varying the length of time taken to deposit the high-refractive-index (n>2 @ λ=1460 nm) DLC film. The advantage of this approach is its speed (the deposition process takes at most 7 minutes) and precision in determining the RI sensitivity of the LPGs.

    In the first portion of this work, 1,2,3,3,4,4-hexafluoro-1,2-bis[4-(dimethylhydroxysilyl)phenoxy]cyclobutane and 1,2,3,3,4,4-hexafluoro-1,2-bis[3-(dimethylhydroxysilyl)phenoxy]cyclobutane were prepared and homopolymerized to afford polymers with excellent thermal stability and Tgs of 27 C and -12 C, respectively. Despite the moderately high wt% of fluorin in the polymer structure (23.8%), these polymers had poor fuel resistance. In fact, swelling measurements indicate that these polymers had apparent solubility parameters of about 18.2 J (exp 1/2) m (exp -3/2) (toluene). Copolymerization of the disilanol monomers with fluorosilicone monomers afforded copolymers containing 20-30 wt% of the perfluorocyclobutane-containing structure displayed adequate fuel resistance, enhanced thermal stability, and a Tg low enough to meet the requirements of a High Speed Civil Transport (HSCT) fuel tank sealant. In the second part of this work, trifluorovinylether-terminated oligomers were prepared and polymerized via cyclodimerization. Initially, an alpha, omega-silanol-terminated fluorosilicone was endcapped with trifluorovinylether end groups via a two-step synthetic sequence. The oligomer was thermally cyclodimerized to a polymer that displayed thermal stability similar to that of a fluorosilicone homopolymer. Second, 1,3-bis[4-trifluorovinyl(oxy)phenyl]-1,3-(3,3,3-trifluoropropyl)dimethyldisiloxane and 1,3-bis{3-trifluorovinyl(oxy)phenyl]-1,3-(3,3,3-trifluoropropyl)dimethyldisiloxane were prepared and cyclodimerized to afford polymers that contained pendant trifluoropropyl groups. The pendant trifluoropropyl groups did enhance solvent resistance in aliphatic hydrocarbon solvents, however, no improvement was observed in aromatic hydrocarbon solvents. These polymers also displayed excellent thermal stability. In the last part of this work, a series of monomers was prepared by the DCC-promoted esterification of 4-[trifluorovinyl(oxy)benzoic acid with alpha, omega

    The presence of circulating antineuronal antibodies has been associated with paraneoplastic neurological syndromes (PNS). Ri antibodies are often associated with lung or breast cancer, but the prevalence of such antibodies in large cancer materials is largely unknown. We used a highly sensitive immunoprecipitation assay to study the level of Ri antibodies in blood samples from 200 patients with small cell lung cancer (SCLC), 253 patients with breast cancer and 557 patients with ovarian cancer. Two hundred blood donors and six Ri positive PNS patients served as controls. The recombinant antigen used in the immunoprecipitation assay was radiolabeled by a coupled in vitro transcription and translation (ITT) technique, enabling low levels of antibodies to be detected. None of the blood donors contained Ri antibodies, whereas all of the sera from the PNS patients were positive. Ri antibodies were present in 4.5% of the patients with SCLC, 0.8% of the patients with breast cancer and in 0.2% of the patients with ovarian cancer. Retesting of the Ri positive samples with immunofluorescense and immune blot showed that the immunoprecipitation technique was more sensitive than the other immune assays. Ri antibodies were not associated with PNS in the patients with breast or ovarian cancer. Neurological data were not available for the SCLC patients, but in these, Ri antibodies were not associated with survival.

  1. The study of resistant mechanisms and reversal in an imatinib resistant Ph+ acute lymphoblastic leukemia cell line.

    In this study, we established an imatinib resistant Ph+ acute lymphoblastic leukemia (ALL) cell line SUP-B15/RI in vitro and studied the mechanism of imatinib resistance. Our results showed that the BCR-ABL1 fusion gene and the mdr1 gene were 6.1 times and 1.7 times, respectively, as high as that of parental SUP-B15 cell line. We found no mutation in the Abl kinase domain of SUP-B15/RI. Furthermore, the detection of cell signaling pathway of PI3K/AKT/mTOR, RAS/RAF, NF-κB, JNK and STAT showed the up-regulation of phosphorylation of AKT, mTOR, P70S6K, and RAF, ERK, and MEK, down-regulation of PTEN and 4EBP-1, and no change in other cell signaling pathways in SUP-B15/RI. However, dasatinib and nilotinib showed partial resistance. Interestingly, bortezomib had no resistance. Imatinib combination with rapamycin had synergistic effect on overcoming the resistance. Altogether, over-expression of BCR-ABL1 and mdr1 gene were involved in the resistance mechanisms, and up-regulation of the cell signaling pathways of PI3K/AKT/mTOR, RAS/RAF in SUP-B15/RI cell line may be correlated with them. The SUP-B15/RI cell line was also resistant to the second generation tyrosine kinase, dasatinib, and nilotinib, not bortezomib. The combination of imatinib with rapamycin can partially overcome the resistance and blockade of the ubiquitin-proteasome can be also a promising pathway to overcome imatinib resistance.

    2007-01-01

    No prospective studies have evaluated the effects of correction of iron deficiency anemia on insulin resistance in non-diabetic premenopausal women with iron deficiency anemia. All patients were treated with oral iron preparations. Insulin resistance was calculated with the Homeostasis Model Assessment formula. All patients were dichotomized by the median for age and BMI to assess how the relationship between iron deficiency anemia and insulin resistance was affected by the age and BMI. Although the fasting glucose levels did not change meaningfully, statistically significant decreases were found in fasting insulin levels following anemia treatment both in the younger age ( = 40 years) and the high BMI (>-27Kg/m) subgroups. Post-treatment fasting insulin levels were positively correlated both with BMI (r=0.386, P=0.004) and post-treatment hemoglobin levels. (r=0.285, P=0.036). Regression analysis revealed that the factors affecting post-treatment insulin levels were BMI (P=0.001) and post-treatment hemoglobin levels (p=0.030). Our results show that following he correction of iron deficiency anemia, insulin levels and HOMA scores decrease in younger and lean non-diabetic premenopausal women. (author)

    2017-12-01

    Public schools and youth voices are largely absent from climate resilience planning and projects in New York City. Additionally, research shows that U.S. science teachers' understanding of climate science is lacking, hence there is not only an urgent need to train and support teachers on both the science and pedagogy of climate change, but to link climate literacy, resilience thinking and service learning in K-12 education. However, research on participation of students and teachers in authentic, civic-oriented experiences points to increased engagement and learning outcomes in science. The Resilient Schools Consortium (RiSC) Project will address all these needs through an afterschool program in six coastal Brooklyn schools that engages teachers and urban youth (grades 6-12), in school and community climate resilience assessment and project design. The RiSC climate curriculum, co-designed by New York City school teachers with Brooklyn College, the National Wildlife Federation, New York Sea Grant and the Science and Resilience Institute at Jamaica Bay, will begin by helping students to understand the difference between climate and weather. The curriculum makes extensive use of existing resources such as NOAA's Digital Coast and the Coastal Resilience Mapping Portal. Through a series of four modules over two school years, the six RiSC teams will; 1. explore and understand the human-induced drivers of climate change and, particularly, the significant climate and extreme weather related risks to their schools and surrounding communities; 2. complete a climate vulnerability assessment within the school and the community that is aligned to OneNYC - the city's resilience planning document; 3. design and execute a school-based resilience project; and 4. propose resilience guidelines for NYC Department of Education schools. At the end of each school year, the six RiSC teams will convene a RiSC summit with city officials and resilience practitioners to share ideas and

  3. The Ri chicken breed and livelihoods in North Vietnam: characterization and prospects

    Directory of Open Access Journals (Sweden)

    Pascal Leroy

    2011-06-01

    Full Text Available For the last twenty years, the consumption of poultry meat has boomed in Vietnam as in the rest of the developing world. Capital-intensive production has grown rapidly to satisfy this demand. Based on a few numbers of genetically uniform strains, these systems threaten biodiversity. In Vietnam, both rural and urban households still keep indigenous chickens as part of a diversified livelihood portfolio. In line with the national in situ conservation strategy, this study approached the context of local poultry keeping in two rural and one suburban districts of Northern Vietnam. It aimed at understanding households’ willingness, constraints and opportunities for practice improvement, including breeds’ management. As the Ri chicken constitutes the large majority of backyard flocks, two particular objectives of this study are the morpho-biometric characterisation of phenotypic diversity among individuals classified as Ri by farmers and an assessment of their productive potential. Chicken was found to hold a different place in livelihoods of the three districts with consequences on the management of genetic resources. The most favourable conditions for improvement of the Ri breed was found in the rural district of Luong-Son, due to market integration. In the more remote district of Ky-Son, living standards were lower and much would be gained from Ri conservation. Ri breed was the most threatened in the suburban Gia-Lam district, where poultry was a minor side-activity, lacking incentive for genetic management. From motives and constraints, tracks about breeding goals are suggested. Further considerations about conservation, improvement, market integration and livelihoods are proposed.

    Studies assessing the effects of protein supplementation on changes in body composition (BC) and health rarely consider the impact of total protein intake (TPro) or the change in TPro (CTPro) from participants' usual diets. This secondary data analysis assessed the impact of TPro and CTPro on changes in BC and metabolic syndrome (MetS) indexes in overweight and obese middle-aged adults who participated in an exercise training program. Men and women [n = 117; age: 50 ± 0.7 y, body mass index (BMI; in kg/m(2)): 30.1 ± 0.3; means ± SEs] performed resistance exercise 2 d/wk and aerobic exercise 1 d/wk and consumed an unrestricted diet along with 200-kcal supplements (0, 10, 20, or 30 g whey protein) twice daily for 36 wk. Protein intake was assessed via 4-d food records. Multiple linear regression model and stratified analysis were applied for data analyses. Among all subjects, TPro and CTPro were inversely associated (P changes in body mass, fat mass (FM), and BMI. Changes in BC were different (P changes in FM, %FM, and %LM. The gain in LM was not different among groups. In addition, MetS indexes were not influenced by TPro and CTPro. In conjunction with exercise training, higher TPro promoted positive changes in BC but not in MetS indexes in overweight and obese middle-aged adults. Changes in TPro from before to during the intervention also influenced BC responses and should be considered in future research when different TPro is achieved via diet or supplements.

    Arbuscular mycorrhizal (AM) fungi are associated with about 80% of land plants. AM fungi provide inorganic nutrients to plants and in return up to 20% of the plant-fixed CO2 is transferred to the fungal symbionts. Since AM fungi are obligate biotrophs, unraveling how sugars are provided to the fungus partner is a key for understanding the functioning of the symbiosis. In this study, we identified two new monosaccharide transporters from Rhizophagus irregularis (RiMST5 and RiMST6) that we characterized as functional high affinity monosaccharide transporters. RiMST6 was characterized as a glucose specific, high affinity H(+) co-transporter. We provide experimental support for a primary role of both RiMST5 and RiMST6 in sugar uptake directly from the soil. The expression patterns of RiMSTs in response to partial light deprivation and to interaction with different host plants were investigated. Expression of genes coding for RiMSTs was transiently enhanced after 48 h of shading and was unambiguously dependent on the host plant species. These results cast doubt on the 'fair trade' principle under carbon-limiting conditions. Therefore, in light of these findings, the possible mechanisms involved in the modulation between mutualism and parasitism in plant-AM fungus interactions are discussed.

    Full Text Available Proteus spp. are opportunistic multidrug resistant enterobacteria associated with diverse clinical diseases in domestic animals. However, Proteus infections in domestic animals are often misdiagnosed or considered contaminants in microbiological cultures rather than a primary agent of disease. Descriptions of Proteus infections in domestic animals are typically restricted to case reports, retrospective studies, or surveillance of other microorganisms. The present study investigated multiple antibiotic resistance indices, minimum inhibitory concentrations (MICs, and ESBL production in 73 strains of Proteus mirabilis (n = 69 and Proteus vulgaris (n = 4 isolated from domestic animals with various clinical manifestations. In dogs, the pathogen was most commonly associated with cystitis (48.21, enteritis (21.42%, otitis (14.29%, and conjunctivitis (3.57%. In bovines, the microorganism was predominant in cases of enteritis (22.22%, abscess (11.11%, otitis (11.11%, omphalitis (11.11%, and peritonitis (11.11%, and in organ fragments (11.11%. In equines (50.0% and cats (100.0%, diarrhea was the main clinical sign. In vitro standard disk diffusion assay showed that the most effective antimicrobials against the isolates were imipenem (98.63, norfloxacin (95.89, amikacin (95.89, levofloxacin (90.41, ceftriaxone (87.64, and florfenicol (87.67. In contrast, the isolates commonly showed resistance to novobiocin (95.89, azithromycin (57.53, and trimethropim/sulfamethoxazole (39.73. Among the 73 isolates, the efficacy of amoxicillin/clavulanic acid, gentamicin, ceftriaxone, and ciprofloxacin according to MICs was 87.67%, 86.30%, 84.93%, and 82.19%, respectively. The MIC50 values of amoxicillin/clavulanic acid, ceftriaxone, ciprofloxacin, and gentamicin were, respectively, 1.0, 0.004, 0.03, and 1.0 µg/mL. Thirty-three strains (45.21% showed a antimicrobial multiple resistance index of ? 0.3. Multidrug resistance profiles of isolates were observed most frequently

    The diagnostic rate of each methods were discussed in thirty six cases and the following conclusions were made. (1.) The diagnostic rate of US, RI, AG and VS was 64.7%, 50%, 57.9%, 60.7% respectively. (2.) Ultrasonography and subtruction-scintigraphy were useful for screening examination for localization of parathyroid tumor. (3.) The reasonable diagnostic procedures were as follows: (1) In the cases of palpable, reno-uretrolithiasic type, and biochemical type: US ..-->.. RI ..-->.. VS. (2) In the cases of nonpalpable osteolytic type, and previous neck surgery: US ..-->.. RI ..-->.. AG ..-->.. VS. These results indicate that the systemic diagnoses are useful to predict localization of parathyroid tumors.

    It is stated that the indexing mechanism described can be used in a nuclear reactor fuel element inspection rig. It comprises a tubular body adapted to house a canister containing a number of fuel elements located longtitudinally, and has two chucks spaced apart for displacing the fuel elements longitudinally in a stepwise manner, together with a plunger mechanism for displacing them successively into the chucks. A measuring unit is located between the chucks for measuring the diameter of the fuel elements at intervals about their circumferences, and a secondary indexing mechanism is provided for rotating the measuring unit in a stepwise manner.

    A fiber Bragg grating written in a photosensitive microfiber using KrF excimer laser via a uniform phase mask is demonstrated. We have successfully fabricated two Bragg gratings in microfibers having different diameters. In the reflection spectrum of a microfiber Bragg grating (MFBG), we observed two reflection peaks,which agrees with our numerical simulation results. Compared with the fundamental mode reflection, the higher-order reflection mode is more sensitive to the refractive index (RI) variation of the surrounding fluid due to its larger evanescent field. The measured maximum sensitivity is ~102 nm/RIU (RI unit) at an RI value of 1.378 in an MFBG with a diameter of 6 μm.

    Three-dimensional (3D) refractive-index (RI) microscopy is an emerging technique suitable for live-cell imaging due to its label-free and fast 3D imaging capabilities. We have developed a common-path system to acquire 3D RI microscopic images of cells with excellent speed and stability. After obtaining 3D RI distributions of individual leukocytes, we used a 3D finite-difference time-domain tool to study light scattering properties. Backscattering spectra of lymphocytes, monocytes and neutrophils are different from each other. Backscattering spectra of lymphocytes matched well with those of homogeneous spheres as predicted by Mie theory while backscattering spectra of neutrophils are significantly more intense than those of the other two types. This suggests the possibility of classifying the three types of leukocytes based on backscattering.

    To describe the distribution of HOMA-IR levels in a general nondiabetic population and its relationships with metabolic and lifestyles characteristics. Cross-sectional study. Data from 2246 nondiabetic adults in a random Spanish population sample, stratified by age and gender, were analyzed. Assessments included a structured interview, physical examination, and blood sampling. Generalized additive models (GAMs) were used to assess the effect of lifestyle habits and clinical and demographic measurements on HOMA-IR. Multivariate GAMs and quantile regression analyses of HOMA-IR were carried out separately in men and women. This study shows refined estimations of HOMA-IR levels by age, body mass index, and waist circumference in men and women. HOMA-IR levels were higher in men (2.06) than women (1.95) (P=0.047). In women, but not men, HOMA-IR and age showed a significant nonlinear association (P=0.006), with increased levels above fifty years of age. We estimated HOMA-IR curves percentile in men and women. Age- and gender-adjusted HOMA-IR levels are reported in a representative Spanish adult non-diabetic population. There are gender-specific differences, with increased levels in women over fifty years of age that may be related with changes in body fat distribution after menopause.

    Recent clinical trials with chimeric antigen receptor (CAR) redirected T cells targeting CD19 revealed particular efficacy in the treatment of leukemia/lymphoma, however, were accompanied by a lasting depletion of healthy B cells. We here explored CD30 as an alternative target, which is validated in lymphoma therapy and expressed by a broad variety of Hodgkin's and non-Hodgkin's lymphomas. As a safty concern, however, CD30 is also expressed by lymphocytes and hematopoietic stem and progenitor cells (HSPCs) during activation. We revealed that HRS3scFv-derived CAR T cells are superior since they were not blocked by soluble CD30 and did not attack CD30(+) HSPCs while eliminating CD30(+) lymphoma cells. Consequently, normal hemato- and lymphopoiesis was not affected in the long-term in the humanized mouse; the number of blood B and T cells remained unchanged. We provide evidence that the CD30(+) HSPCs are protected against a CAR T-cell attack by substantially lower CD30 levels than lymphoma cells and higher levels of the granzyme B inactivating SP6/PI9 serine protease, which furthermore increased upon activation. Taken together, adoptive cell therapy with anti-CD30 CAR T cells displays a superior therapeutic index in the treatment of CD30(+) malignancies leaving healthy activated lymphocytes and HSPCs unaffected.

A number of policies controlling the bulk movement of data based on user requirements for persistency......Data warehouses (DWs) have traditionally been loaded with data at regular time intervals, e.g., monthly, weekly, or daily, using fast bulk loading techniques. Recently, the trend is to insert all (or only some) new source data very quickly into DWs, called near-realtime DWs (right-time DWs......). This is done using regular INSERT statements, resulting in too low insert speeds.

  7. An iterative correction approach used to retrieve the refractive index of squid pigment aerosols

    Science.gov (United States)

    2018-03-01

    Pigments localized within cephalopod chromatophores are important for dermal coloration. When isolated and used as materials outside of the animal, the pigments can be processed as aerosols, illustrating a potential application for spray-on-coatings. The optical features of the pigment aerosols are difficult to analyze and require a method to correct for the particle charging and solvent effects accumulated during the aerosolizing process. We describe a method to account for these effects using an innovative iterative approach tied to retrieved refractive index (RI) values. RI retrievals were obtained via the best fit between the corrected, experimentally observed extinction efficiencies compared to those calculated by Mie theory for a specific RI at selected sizes. In addition to these retrievals, the impact of solvent on the particles’ optical properties was also examined via the Maxwell-Garnett mixing rule. Ultimately, we obtained a pigment RI with a real portion (n) of 1.66 (±0.05) representing a lower limit and an imaginary portion (k) of 0.13 (±0.08)i representing an upper limit for the generated aerosols. Combined, this approach advances techniques used to retrieve RI values that benefits both atmospheric chemistry and bio-inspired materials.

  8. Structured illumination for 3D subdiffraction reconstruction of refractive-index and fluorescence (Conference Presentation)

    Science.gov (United States)

    Chowdhury, Shwetadwip; Izatt, Joseph A.

    2017-02-01

    Refractive-index (RI) is an inherent optical property of materials that can provide important biochemical and biophysical information about a biological sample. Optical-diffraction-tomography (ODT) is a current standard to obtain quantitative three-dimensional RI distributions, by measuring optical fields diffracted from the sample by rotated illumination beams. This method for ODT also synthetically enlarges the microscope's lateral spatial-frequency support, and thus images the RI distribution with lateral resolution beyond the microscope's coherent diffraction limit. Fluorescence microscopy offers a complementary set of biological insights by offering imaging capabilities with molecular specificity. Analogous to ODT, super-resolution fluorescence techniques can offer these insights at spatial resolutions beyond the microscope's incoherent diffraction limit. Unfortunately, such super-resolution techniques are generally incompatible with ODT and a generalized sub-diffraction technique has been difficult to find, which hinders a cohesive, high-resolution, multimodal analysis of biological samples. We experimentally introduce, for the first time to our knowledge, a novel, high resolution, optical system that uses structured illumination (SI) to enable 3D sub-diffraction resolution imaging for both fluorescence and RI. We demonstrate sub-diffraction resolution, multimodal SI imaging of HT29 and MCF7 cells fluorescently stained for F-actin, such that the 3D RI and fluorescent distributions may offer unique, but complementary, insights into the biological samples.

    The remains of an ancient wooden boat were unearthed at the Bibong-ri shell mound site. The site was located at Bibong-ri, Bugog-myeon, Changnyeong-gun, Gyeongsangnam-do in South Korea. A substantial fragment of the vessel was discovered in the lowest layer of the site. We collected 17 samples of charcoal and wood from pebble, sand, and shell layers. Sample preparation extracted the carbon from each sample material and converted it into graphite for AMS radiocarbon dating. Radiocarbon dates of the samples indicate that they belong to the Neolithic period and that the boat dates from ca. 5700 BC. To this point, the oldest known boat in the world has been a wooden boat dating from ca. 5500 BC in China. Other ancient boats from around the world include a logboat dating from ca. 3600 BC in Japan and a fleet of wooden boats dating from ca. 3000 BC in Egypt. The Bibong-ri boat is the first boat from the Neolithic period ever found in South Korea and must represent one of the world's oldest known boats.

    Emdogain, containing an extract of fetal porcine enamel matrix proteins, is a potent stimulator of in vitro osteoclastogenesis. The underlying molecular mechanisms are, however, unclear. Here, we have addressed the role of transforming growth factor-beta receptor type 1 (TGF-βRI) kinase activity on osteoclastogenesis in murine bone marrow cultures. Inhibition of TGF-βRI kinase activity with SB431542 abolished the effect of Emdogain on osteoclastogenesis induced by receptor activator of nuclear factor kappa-B ligand or tumor necrosis factor-alpha. SB431542 also suppressed the Emdogain-mediated increase of OSCAR, a co-stimulatory protein, and dendritic cell-specific transmembrane protein and Atp6v0d2, the latter two being involved in cell fusion. Similar to transforming growth factor-beta1 (TGF-β), Emdogain could not compensate for the inhibition of IL-4 and IFNγ on osteoclast formation. When using the murine macrophage cell line RAW246.7, SB431542 and the smad-3 inhibitor SIS3 blocked Emdogain-stimulated expression of the transcription factor NFATc1. Taken together, the data suggest that TGF-βRI kinase activity is necessary to mediate in vitro effects of Emdogain on osteoclastogenesis. Based on these in vitro data, we can speculate that at least part of the clinical effects of Emdogain on osteoclastogenesis is mediated via TGF-β signaling.

    Full Text Available Abstract Background There is increasing evidence that the existence of systemic inflammation response is correlated with poor prognosis in several solid tumors. The aim of this retrospective study was to investigate the association between systemic immune-inflammation index (SII and therapy response and overall survival in patients with stage III non-small cell lung cancer (NSCLC. The prognostic values of neutrophil to lymphocyte ratio (NLR, platelet to lymphocyte ratio (PLR, and prognostic nutritional index (PNI were also evaluated. Methods In total, 332 patients with new diagnosis of stage III NSCLC were included in this retrospective analysis. SII was defined as platelet counts × neutrophil counts/lymphocyte counts. Receiver operating characteristic (ROC curve was used to evaluate the optimal cut-off value for SII, NLR, PLR and PNI. Univariate and multivariate survival analysis were performed to identify the factors correlated with overall survival. Results Applying cut-offs of ≥ 660 (SII, ≥ 3.57 (NLR, ≥ 147 (PLR, ≤ 52.95 (PNI, SII ≥ 660 was significantly correlated with worse ECOG PS (< 0.001, higher T stage (< 0.001, advanced clinical stage (p = 0.019, and lower response rate (p = 0.018.

    Calderón-Garcidueñas, Lilian; de la Monte, Suzanne M

    2017-01-01

    Given the epidemiological trends of increasing Alzheimer's disease (AD) and growing evidence that exposure and lifestyle factors contribute to AD risk and pathogenesis, attention should be paid to variables such as air pollution, in order to reduce rates of cognitive decline and dementia. Exposure to fine particulate matter (PM2.5) and ozone (O3) above the US EPA standards is associated with AD risk. Mexico City children experienced pre- and postnatal high exposures to PM2.5, O3, combustion-derived iron-rich nanoparticles, metals, polycyclic aromatic hydrocarbons, and endotoxins. Exposures are associated with early brain gene imbalance in oxidative stress, inflammation, innate and adaptive immune responses, along with epigenetic changes, accumulation of misfolded proteins, cognitive deficits, and brain structural and metabolic changes. The Apolipoprotein E (APOE) 4 allele, the most prevalent genetic risk for AD, plays a key role in the response to air pollution in young girls. APOE 4 heterozygous females with >75% to <94% BMI percentiles are at the highest risk of severe cognitive deficits (1.5-2 SD from average IQ). This review focused on the relationships between gender, BMI, systemic and neural inflammation, insulin resistance, hyperleptinemia, dyslipidemia, vascular risk factors, and central nervous system involvement in APOE4 urbanites exposed to PM2.5 and magnetite combustion-derived iron-rich nanoparticles that can reach the brain. APOE4 young female heterozygous carriers constitute a high-risk group for a fatal disease: AD. Multidisciplinary intervention strategies could be critical for prevention or amelioration of cognitive deficits and long-term AD progression in young individuals at high risk.

  4. Influence of LAR and VAR on Para-Aminopyridine Antimalarials Targetting Haematin in Chloroquine-Resistance.

    Warhurst, David C; Craig, John C; Raheem, K Saki

    2016-01-01

    Antimalarial chloroquine (CQ) prevents haematin detoxication when CQ-base concentrates in the acidic digestive vacuole through protonation of its p-aminopyridine (pAP) basic aromatic nitrogen and sidechain diethyl-N. CQ export through the variant vacuolar membrane export channel, PFCRT, causes CQ-resistance in Plasmodium falciparum but 3-methyl CQ (sontochin SC), des-ethyl amodiaquine (DAQ) and bis 4-aminoquinoline piperaquine (PQ) are still active. This is determined by changes in drug accumulation ratios in parasite lipid (LAR) and in vacuolar water (VAR). Higher LAR may facilitate drug binding to and blocking PFCRT and also aid haematin in lipid to bind drug. LAR for CQ is only 8.3; VAR is 143,482. More hydrophobic SC has LAR 143; VAR remains 68,523. Similarly DAQ with a phenol substituent has LAR of 40.8, with VAR 89,366. In PQ, basicity of each pAP is reduced by distal piperazine N, allowing very high LAR of 973,492, retaining VAR of 104,378. In another bis quinoline, dichlorquinazine (DCQ), also active but clinically unsatisfactory, each pAP retains basicity, being insulated by a 2-carbon chain from a proximal nitrogen of the single linking piperazine. While LAR of 15,488 is still high, the lowest estimate of VAR approaches 4.9 million. DCQ may be expected to be very highly lysosomotropic and therefore potentially hepatotoxic. In 11 pAP antimalarials a quadratic relationship between logLAR and logResistance Index (RI) was confirmed, while log (LAR/VAR) vs logRI for 12 was linear. Both might be used to predict the utility of structural modifications.

  6. Ptolemaic indexing

    Magnus Lie Hetland

    2015-07-01

    Full Text Available This paper discusses a new family of bounds for use in similarity search, related to those used in metric indexing, but based on Ptolemy's inequality, rather than the metric axioms. Ptolemy's inequality holds for the well-known Euclidean distance, but is also shown here to hold for quadratic form metrics in general, with Mahalanobis distance as an important special case. The inequality is examined empirically on both synthetic and real-world data sets and is also found to hold approximately, with a very low degree of error, for important distances such as the angular pseudometric and several Lp norms. Indexing experiments are performed on several data sets, demonstrating a highly increased filtering power when using certain forms of Ptolemaic filtering, compared to existing, triangular methods. It is also shown that combining the Ptolemaic and triangular filtering can lead to better results than using either approach on its own.

    Male drivers in the 16- to 19-year age group have a nine-fold increase in their crash risk compared with 25- to 34-year-olds who have a relative risk of 2.3. Crash risk in young drivers has been directly linked to risk-taking behaviour. This paper reports the development of a video risk assessment tool for use with drivers. This paper reports on the process of validating and investigating the reliability of the Occupational Therapy Risk Propensity Test (OT-RiPT) to measure risk-taking propensity. 20 healthy male participants were recruited. OT-RiPT scores were correlated with driving experience. Internal consistency was investigated using Cronbach's alpha. Face validity was established. The OT-RiPT and a validated driver behaviour questionnaire were administered and the results correlated to establish discriminant validity. There was no significant correlation between driving experience and OT-RiPT scores. Good internal consistency was established. OT-RiPT has high face validity. Discriminant validity was demonstrated. Pending further testing, OT-RiPT shows promise as a reliable and valid measure of risk-taking propensity in young drivers.

    Evaluation has been performed for Inventory Change Report (ICR) in 2008/2009 - 2012/2013 in MBA.RI-B (MBA = Material Balance Area) (RI-B = Center for Accelerator and Material Process Technology). The evaluation performed on the inventory change report of nuclear material document. Changes in inventories occur when there is acceptance or shipment of nuclear materials outside nuclear facilities.

    This paper presents a long-period fiber-grating (LPG) based Michelson interferometric refractometry to monitor the change in refractive index of porcine muscle during laser-induced interstitial thermotherapy (LITT). As the wavelength of RI interferometer alters with the change in refractive index around the probe, the LPG based refractometry is combined with LITT system to measure the change in refractive index of porcine muscle when irradiated by laser. The experimental results show the denaturation of tissue alters the refractive index significantly and the LPG sensor can be applied to monitor the tissue state during the LITT.

    Sugar profiles of different almond and chestnut cultivars were obtained by high-performance liquid chromatography (HPLC), by means of a refractive index (RI) detector. A solid-liquid extraction procedure was used in defatted and dried samples. The chromatographic separation was achieved using a Eurospher 100-5 NH(2) column using an isocratic elution with acetonitrile/water (70:30, v/v) at a flow rate of 1.0 ml/min. All the compounds were separated in 16 min. The method was optimized and proved to be reproducible and accurate. Generally, more than 95% of sugars were identified for both matrixes. Sugars profiles were quite homogeneous for almond cultivars; sucrose was the main sugar (11.46 +/- 0.14 in Marcona to 22.23 +/- 0.59 in Ferragnes g/100 g of dried weight), followed by raffinose (0.71 +/- 0.05 in Ferraduel to 2.11 +/- 0.29 in Duro Italiano), glucose (0.42 +/- 0.12 in Pegarinhos two seeded to 1.47 +/- 0.19 in Ferragnes) and fructose (0.11 +/- 0.02 in Pegarinhos two seeded to 0.59 +/- 0.05 in Gloriette). Commercial cultivars proved to have higher sucrose contents, except in the case of Marcona. Nevertheless, chestnut cultivars revealed a high heterogeneity. Sucrose was the main sugar in Aveleira (22.05 +/- 1.48), Judia (23.30 +/- 0.83) and Longal (9.56 +/- 0.91), while glucose was slightly prevalent in Boa Ventura (6.63 +/- 0.49). The observed variance could serve for inter-cultivar discrimination.

  19. Improving the efficiency of copper indium gallium (Di-selenide (CIGS solar cells through integration of a moth-eye textured resist with a refractive index similar to aluminum doped zinc oxide

    Full Text Available Textured transparent conductors are widely used in thin-film silicon solar cells. They lower the reflectivity at interfaces between different layers in the cell and/or cause an increase in the path length of photons in the Si absorber layer, which both result in an increase in the number of absorbed photons and, consequently, an increase in short-circuit current density (Jsc and cell efficiency. Through optical simulations, we recently obtained strong indications that texturing of the transparent conductor in copper indium gallium (di-selenide (CIGS solar cells is also optically advantageous. Here, we experimentally demonstrate that the Jsc and efficiency of CIGS solar cells with an absorber layer thickness (dCIGS of 0.85 μm, 1.00 μm and 2.00 μm increase through application of a moth-eye textured resist with a refractive index that is sufficiently similar to AZO (nresist = 1.792 vs. nAZO = 1.913 at 633 nm to avoid large optical losses at the resist-AZO interface. On average, Jsc increases by 7.2%, which matches the average reduction in reflection of 7.0%. The average relative increase in efficiency is slightly lower (6.0%. No trend towards a larger relative increase in Jsc with decreasing dCIGS was observed. Ergo, the increase in Jsc can be fully explained by the reduction in reflection, and we did not observe any increase in Jsc based on an increased photon path length.

    IgE-antigen-dependent crosslinking of the high affinity IgE receptor (Fc{epsilon}RI) on mast cells leads to degranulation, leukotriene synthesis and cytokine production. Calcium (Ca{sup 2+}) mobilization is a sine qua non requisite for degranulation, allowing the rapid secretion of stored pro-inflammatory mediators responsible for allergy symptoms. Fyn is a Src-family kinase that positively controls Fc{epsilon}RI-induced mast cell degranulation. However, our understanding of the mechanism connecting Fyn activation to secretion of pre-synthesized mediators is very limited. We analyzed Fc{epsilon}RI-dependent Ca{sup 2+} mobilization in bone marrow-derived mast cells (BMMCs) differentiated from WT and Fyn -/- knock out mice. Fyn -/- BMMCs showed a marked defect in extracellular Ca{sup 2+} influx after Fc{epsilon}RI crosslinking but not after thapsigargin addition. High concentrations of Gadolinium (Gd{sup 3+}) partially blocked Fc{epsilon}RI-induced Ca{sup 2+} influx in WT cells but, in contrast, completely inhibited Ca{sup 2+} mobilization in Fyn -/- cells. Low concentrations of an inhibitor of the canonical transient receptor potential (TRPC) Ca{sup 2+} channels (2-aminoethoxyphenyl-borane, 2-APB) blocked Fc{epsilon}RI-induced maximal Ca{sup 2+} rise in WT but not in Fyn -/- cells. Ca{sup 2+} entry through Fyn-controlled, 2-APB sensitive channels was found to be important for full degranulation and IL-2 mRNA accumulation in WT cells. Immunoprecipitation assays showed that Fyn kinase interacts with TRPC 3/6/7 channels after IgE-antigen stimulation, but its association is not related to protein tyrosine phosphorylation. Results indicate Fyn kinase mediates the receptor-dependent activation of TRPC channels that contribute to degranulation in Fc{epsilon}RI-stimulated mast cells.

    RI plethysmography with Tc-99m human serum albumin was performed to determine the effectiveness of preoperative chemotherapy performed in 14 patients with malignant bone tumor. It failed to detect blood changes before and after chemotherapy in 2 patients with bone tumor of telangiectatic type. In the other 12 patients, changes in blood flow during the process of treatment were depicted on plethysmograms. It preceded the other techniques for chemotherapeutic evaluation in 2 patients. It was considered useful in the early evaluation of chemotherapy, if combined with other imaging examinations to detect morphological changes. (N.K.).

    Careful palpation, plain X-rays and angiography are useful in the diagnosis of lateral cervical masses, but accurate preoperative evaluation sometimes needs further examinations. Recently several new auxiliary procedures have become available such as RI-scintigraphy, Ultrasound, and CT-scanning but even these may not be sufficient when used singly. When all these procedures were combined preoperatively in the case of lateral cervical masses and the results were compared with the findings at time of surgery and the pathology of the extirpated masses, acurate preoperative diagnose were possible.

Contrast-enhanced MRA was performed in 321 PAD patients using a 1.5T MR scanner with moving bed technique. The ROR and resting ABI were determined in each patient's leg and correlation analysis was performed using the Pearson test. A significant negative correlation (r = -.513; pROR (mean 11.03±5.42) and resting ABI (mean .81±.26) was identified. An even more pronounced correlation was found in patients younger than median age who had higher ABI values (r = -.608; pROR scoring system evaluated in this series correlates better with the ABI than previously published scoring systems and could be suggested as reporting system for routine MRA evaluation.

    Full Text Available The recently proposed "Respiration Index" (RI = log PO2/PCO2 suggests that aerobic metabolism is limited by the ratio of reactants (oxygen to products (carbon dioxide according to the thermodynamics of cellular respiration. Here, we demonstrate further that, because of the large standard free energy change for organic carbon oxidation (ΔG° = −686 kcal mol−1, carbon dioxide can never reach concentrations that would limit the thermodynamics of this reaction. A PCO2 to PO2 ratio of 10503 would be required to reach equilibrium (equilibrium constant, Keq = 10503, where ΔG = 0. Thus, a Respiration Index of −503 would be the real thermodynamic limit to aerobic life. Such a Respiration Index is never reached, either in the cell or in the environment. Moreover, cellular respiration and oxygen provision are kinetically controlled such that, within limits, environmental oxygen and CO2 concentrations have little to do with intracellular concentrations. The RI is fundamentally different from the aragonite saturation state, a thermodynamic index used to quantify the potential effect of CO2 on calcification rates, because of its failure to incorporate the equilibrium constant of the reaction. Not only is the RI invalid, but its use leads to incorrect and misleading predictions of the threat of changing oxygen and carbon dioxide to marine life. We provide a physiological framework that identifies oxygen thresholds and allows for synergistic effects of ocean acidification and global warming.

    To evaluate the clinical significance of RI images of hepatic blood flow using Tc-99m-PMT, analysis of the RI images and estimation of hepatic blood flow were carried out in patients with various liver diseases (37 cases). After intravenous injection of Tc-99m-PMT, hepatic accumulation curve of ROI positioned at whole liver area and time activity curve of ROI positioned at celiac artery were obtained through scintillation camera images with the computer-analysed system. Hepatic blood flow coefficient (K) was calculated from the hepatic accumulation curve. Based on the differential curve calculated from the time activity curve, chronological images of arterial, portal, parenchymal and saturated parenchymal phases were obtained. Results ; 1) K was 0.50 + 0.04, 0.35 + 0.02 and 0.26 + 0.04/min in normal type, CH type and LC type respectively. These coefficients well correlated with clinical severity of hepatic diseases. 2) Perfusional phase images of the liver became poorer in accordance with progression of liver disease, while images of spleen, portal venous system and collateral channels were more clearly obtained in liver cirrhosis. This method was shown to have a potential to understanding of severity of liver disease and hepatic blood flow dynamics.

  15. Strongyloides ratti: implication of mast cell-mediated expulsion through FcεRI-independent mechanisms

    2009-09-01

    Full Text Available In order to examine whether FcεRI-dependent degranulation of intestinal mast cells is required for expulsion of intestinal nematode Strongyloides ratti, CD45 exon6-deficient (CD45-/- mice were inoculated with S. ratti. In CD45-/- mice, egg excretion in feces persisted for more than 30 days following S. ratti larvae inoculation, whereas in wild-type (CD45+/+ mice, the eggs completely disappeared by day 20 post-infection. The number of intestinal mucosal mast cells, which are known effector cells for the expulsion of S. ratti, was 75% lower in CD45-/- mice compared with that in CD45+/+ mice. Adoptive transfer of wild-type T cells from CD45+/+ mice into CD45-/- mice reduced the duration of S. ratti infection to comparable levels observed in CD45+/+ mice, with concomitant increases in intestinal mucosal mast cells. These results showed that CD45 is not involved in the effector function of intestinal mucosal mast cells against S. ratti infection. Since FcεRI-dependent degranulation of mast cells is completely impaired in these CD45 knockout mice, we conclude that FcεRIdependent degranulation is not required in the protective function of intestinal mucosal mast cells against primary infection of S. ratti.

    The EcoRI restriction endonuclease requires one divalent metal ion in each of two symmetrical and identical catalytic sites to catalyse double-strand DNA cleavage. Recently, we showed that Cu2+ binds outside the catalytic sites to a pair of new sites at H114 in each sub-unit, and inhibits Mg2+-catalysed DNA cleavage. In order to provide more detailed structural information on this new metal ion binding site, we performed W-band (∼94 GHz) and X-band (∼9.5 GHz) electron spin resonance spectroscopic measurements on the EcoRI-DNA-(Cu2+)2 complex. Cu2+ binding results in two distinct components with different gzz and Azz values. X-band electron spin echo envelope modulation results indicate that both components arise from a Cu2+ coordinated to histidine. This observation is further confirmed by the hyperfine sub-level correlation results. W-band electron nuclear double resonance spectra provide evidence for equatorial coordination of water molecules to the Cu2+ ions.

    In animals, RNA binding proteins (RBPs) and microRNAs (miRNAs) post-transcriptionally regulate the expression of virtually all genes by binding to RNA. Recent advances in experimental and computational methods facilitate transcriptome-wide mapping of these interactions. It is thought that the combinatorial action of RBPs and miRNAs on target mRNAs form a post-transcriptional regulatory code. We provide a database that supports the quest for deciphering this regulatory code. Within doRiNA, we are systematically curating, storing and integrating binding site data for RBPs and miRNAs. Users are free to take a target (mRNA) or regulator (RBP and/or miRNA) centric view on the data. We have implemented a database framework with short query response times for complex searches (e.g. asking for all targets of a particular combination of regulators). All search results can be browsed, inspected and analyzed in conjunction with a huge selection of other genome-wide data, because our database is directly linked to a local copy of the UCSC genome browser. At the time of writing, doRiNA encompasses RBP data for the human, mouse and worm genomes. For computational miRNA target site predictions, we provide an update of PicTar predictions.

    A novel refractive index (RI) sensor head is proposed and experimentally demonstrated in this paper. The proposed sensor head is composed of a segment of bared single-mode fiber and a fiber holder that is fabricated by a 3D printer. The mechanism of the sensor head is based on dual polarized Mach-Zehnder interference. According to the aforementioned mechanism, we derived that the RI responses of the resonance dips possess an exponential functional manner when the E field is along the fast or slow axes. In addition, based on the finite element method, we found that the resonance dips wavelength responses are more sensitive when the input E field is along the fast axis. A confirmation experiment was performed, and the results confirmed our hypothesis. The maximum arithmetic mean value of RI response is about 657.895  nm/RIU for the proposed sensor head when the ambient RI changes from 1.3350 to 1.4110. Moreover, in the case of the proposed liquid RI sensor head, aligning the E field along the fast axis is the potentially needed condition for polarization.

    We adapted the critical angle method for measuring rough surfaces under partial contact to acquire an in vivo skin refractive index (RI). Assuming that the total reflection is the simple sum of reflection from areas that are in contact and reflection from those that are not in contact, the RI can be estimated even for partial contact with a rough surface. We found that cheek skin is sufficiently soft that a sufficiently large area can be in contact and that the critical angle was detectable. The RIs of the cheeks of adult females were measured. The RI range was about 1.51 to 1.53, at a wavelength of 550 nm, without considering systematic errors. The RIs of cheeks are significantly correlated with their conductance, which corresponds to their water content. We determined the relationship between the RI and conductance within the variation of skin under normal conditions; this relationship was theoretically obtained in previous studies. In the present study, a direct in vivo measurement method was developed that enabled us to measure the RI in daily life, although this method contains errors for several reasons, including disregarding absorption.

  1. Reviewer index: a new proposal of rewarding the reviewer.

    Science is strengthened not by research alone, but by publication of original research articles in international scientific journals that gets read by a global scientific community. Research publication is the 'heart' of a journal and the 'soul' of science - the outcome of collective efforts of authors, editors and reviewers. The publication process involves author-editor interaction for which both of them get credit once the article gets published - the author directly, the editor indirectly. However, the remote reviewer who also plays a key role in the process remains anonymous and largely unrecognised. Many potential reviewers therefore, stay away from this 'highly honorary' task. Appropriate peer review controls quality of an article and thereby ensures quality and integrity of the journal. Recognising and rewarding the role of the reviewer is therefore vital. In this article, we propose a novel idea of Reviewer Index (RI), Reviewer Index Directory (RID) and Global Reviewer Index Directory (GRID), which will strengthen science by focussing on the reviewer, as well as the author. By adopting this innovative Reviewer Centric Approach, a new breed of well-trained reviewers of high quality and sufficient quantity will be available for eternity. Moreover, RI, RID and GRID would also enable grading and ethical rewarding of reviewers.

    Full Text Available Background. Women with a history of both parental type 2 diabetes (pt2DM and previous gestational diabetes (pGDM represent a group at high risk of cardiovascular events. We hypothesized that pGDM changes cardiometabolic risk markers levels as well as theirs associations with glucose indices in nondiabetic pt2DM women. Methods. Anthropometric parameters, glucose regulation (OGTT, insulin resistance (HOMA-IR, beta-cell function, lipid levels, parameters of endothelial dysfunction, and inflammation were evaluated in 55 women with pt2DM, 40 with both pt2DM and pGDM 2–24 months postpartum, and 35 controls. Results. Prediabetes was diagnosed more frequently in women with both pt2DM and pGDM in comparison with women with only pt2DM (10 versus 8, P=0.04. The pGDM group had higher LDL-cholesterol, sICAM-1, tPa Ag, fibrinogen, and lower beta-cell function after adjustment for HOMA-IR, in comparison with pt2DM group. In pt2DM group postchallenge glucose correlated independently with hsCRP and in pGDM group fasting glucose with HOMA-IR. Conclusions. pGDM exerts a combined effect on cardiometabolic risk markers in women with pt2DM. In these women higher LDL-cholesterol, fibrinogen, sICAM-1, tPa Ag levels and decreased beta cell function are associated with pGDM independently of HOMA-IR index value. Fasting glucose is an important cardiometabolic risk marker and is independently associated with HOMA-IR.

    2014-05-01

    This paper reports a temperature-compensated fiber-optic refractive index (RI) sensor for high sensitivity measurement. The sensor includes a piece of fused-silica capillary (FSC) and a fiber Bragg grating (FBG), both of which are sandwiched by single-mode fibers (SMFs). When light from the lead-in SMF enters into the wall of the FSC that acts as a RI sensing element, multiple modes are excited and interfere to form fringes collected by the lead-out SMF. The FBG is fabricated adjunct to the FSC to compensate its temperature sensitivity. The FSC based sensor prototype is fabricated and sealed in a flow cell to test its performance. Experimental results show that the sensor is highly sensitive to RI, and the sensitivity in the tested RI range from 1.33 to 1.35 is 698.52 nm/RIU and from 1.35 to 1.37 is 1061.78 nm/RIU. The temperature sensitivity of the FSC is -0.173 nm/°C, which is compensated by the FBG. This capillary wall based sensor can be further developed as a miniaturized fiber optic biosensor for biochemical application.

    We present a pilot demonstration of an optical fiber based refractive index (RI) sensor involving the deposition of graphene onto the surface of a segment of a photonic crystal fiber (PCF) in a fiber-based Mach-Zehnder Interferometer (MZI). The fabrication process is relatively simple and only involves the fusion splicing of a PCF between two single mode fibers. The deposition process relies only on the cold transfer of graphene onto the PCF segment, without the need for further physical or chemical treatment. The graphene overlay modified the sensing scheme of the MZI RI sensor, allowing the sensor to overcome limitations to its detectable RI range due to free spectral range issues. This modification also allows for continuous measurements to be obtained without the need for reference values for the range of RIs studied and brings to light the potential for simultaneous dual parameter sensing. The sensor was able to achieve a RI sensitivity of 9.4 dB/RIU for the RIs of 1.33-1.38 and a sensitivity of 17.5 dB/RIU for the RIs of 1.38-1.43. It also displayed good repeatability and the results obtained were consistent with the modeling.

  8. Refractive index measurements of multiple layers using numerical refocusing in FF-OCT.

    We propose and demonstrate the novel method of refractive index (RI) measurement for each layer of multilayered samples, which is based on numerical refocusing in full field optical coherence tomography (FF-OCT). The en-face FF-OCT image on an inner layer boundary of a multilayered sample is unintentionally blurred or defocused due to the RI of the sample itself, but can be numerically refocused. The refocusing is performed by numerically shifting the image sensor plane of the system, in general. However, by calculating the corresponding sample shift and then compared it with the actual sample shifting distance, we could extract the average RI of the layer between any two layer boundaries within the multilayered sample. In addition, the thickness of that particular layer could be derived at the same time. For the idea proof, several samples were prepared by stacking, for each sample, two transparent plates with a gap in between. While changing the material of the plate and filling the gap with oil, the RIs of the plate and the oil were measured. For oils of various RIs, from 1.2977 to 1.3857, the measured RIs were well matched with the reported ones within 0.205%. Moreover, even with a stack of various and multiple plates in front of the same oil layer, the oil RI and the physical thickness of the oil layer were extracted with average errors of only 0.065% and 0.990%, respectively.

    We report optimized auxiliary basis sets for use with the Karlsruhe segmented contracted basis sets including moderately diffuse basis functions (Rappoport and Furche, J. Chem. Phys., 2010, 133, 134105) in resolution-of-the-identity (RI) post-self-consistent field (post-SCF) computations for the elements H-Rn (except lanthanides). The errors of the RI approximation using optimized auxiliary basis sets are analyzed on a comprehensive test set of molecules containing the most common oxidation states of each element and do not exceed those of the corresponding unaugmented basis sets. During these studies an unsatisfying performance of the def2-SVP and def2-QZVPP auxiliary basis sets for Barium was found and improved sets are provided. We establish the versatility of the def2-SVPD, def2-TZVPPD, and def2-QZVPPD basis sets for RI-MP2 and RI-CC (coupled-cluster) energy and property calculations. The influence of diffuse basis functions on correlation energy, basis set superposition error, atomic electron affinity, dipole moments, and computational timings is evaluated at different levels of theory using benchmark sets and showcase examples.

    Despite of stiffening change of conduit arteries, how total peripheral resistance (TPR) is adapted to chronic spinal cord injury (SCI) remains unclear. To investigate how chronic cervical SCI influences hemodynamic characteristics Cross-sectional, case-control study. Rehabilitation department in the tertiary medical center. Twenty-one male patients with traumatic SCI resulting from cervical spine fracture were recruited. The injury occurred three to 289 months (46 months in average) previously. Twenty-one healthy male participants with matched age and body mass index were enrolled as control group. The subjects were asked to maintain supine rest (SR) and then head-up tilt (HUT) at 60 degree for five minutes, respectively. A novel noninvasive bio-reactance device was employed to measure cardiac hemodynamics, whereas heart rate variability was used to determine cardiac autonomic activity. Additionally, the digital volume pulse analysis was applied to calculate arterial stiffness index (SI) and arteriolar reflection index (RI). SCI patients revealed less stroke volume and cardiac output (CO), as well as, greater total peripheral resistance (TPR) and SI during SR than normal subjects did. Moreover, the positive correlation between TPR and SI was observed in SCI patients rather than normal subjects. In SCI patients, HUT (1) markedly decreased TPR while CO and cardio-acceleration responses remained intact and (2) decreased HF power value but failed to change LF/HF ratio. Furthermore, the degree of orthostatic hypotension was correlated with the TPRHUT/TPRSR ratio but not the COHUT/COSR ratio. Chronic cervical SCI leads to a progressively accelerated increase in vascular stiffness, which is associated with increase in systemic vascular resistance. Furthermore, the cervical SCI-related orthostatic hypotension lies in the impairment of vasoconstriction without cardiac dysfunction. Clinical Rehabilitation Impact. SI, rather than blood pressure, reflects not only

    A new injector linac "RILAC2", has recently been constructed at the RIKEN RI Beam Factory. The main part of the RILAC2 is a drift tube linac that consists of three newly designed cavities. These cavities operate in continuous wave (CW) mode at a fixed frequency of 36.5 MHz. Their structure is based on a quarter-wavelength resonator because this is the smallest resonator available in this frequency range among the available structures. We adopted the direct coupling method in the construction of these cavities. A power amplifier was directly coupled to the cavity without a long transmission line to reduce the installation area and simultaneously reduce construction cost. A detailed cavity and coupler design was carried out via simulation. Our work also describes the design process using three-dimensional electromagnetic simulation software. Construction and operation tests are also shown.

    New BV(RI) C measurements of Praesepe made at the South African Astronomical Observatory (SAAO) are presented. When those measurements are combined with those reported in previous papers in this series, it is found that they support previously determined V zero points for Praesepe, M67, and the Hyades. Support is also found for joint (V – R) C and (R – I) C zero points established previously for Praesepe and NGC 752. For the SAAO system of standard stars, a B – V correction to the Johnson system of about –9 mmag appears to be reasonably well established. The preferred (though not definitive) V correction is about +7 mmag. For the Landolt V system, zero-point identity with the Johnson system at a 2σ level of 4.8 mmag is found, and no color term as large as 4 mmag (mag) –1 is detected. Updated CDS data files for Praesepe are briefly described.

    ENEA and the Egadi Islands Marine Protected Area (MPA) have completed some experiments in order to recover and use seagrass wrack for the restoration of emerged and submerged coastal areas in Favignana Island (Western Sicily, Italy). A multipurpose facility built with beached biomass, comprising a casing made of biocompatible fibre and filled with wrack harvested from the beaches, has been implemented. The canvas has a mesh greater than a specific dimension, and biocompatible fibres have undergone transverse and longitudinal tensile strength. It is a structure made of natural materials and eligible for multi-purpose applications, that is used for the realization of “mats” stuffed with seagrass wrack, collected from emerged beaches. The results of such realisation under the GE.RI.N project were the increased carrying capacity of the beaches as the removal of beached biomass and the disposal of the structures on rocky shores enhance the available area for tourist recreation and bathing. The structures are also suitable as a substrate for the re-establishment of seagrass shoots on the sea bottom, which is essential for maintaining the presence of the meadow to reduce coastal erosion. As part of the GE.RI.N project, the patent number RM2014A000151, registered on March 24, 2014, has been deposited and is now available for licensing. A design implementation of the structure is under development in collaboration with the University of Rome “Sapienza” – Architecture Science in Product Design, as part of a degree thesis project, titled Medonia [it

    Novel immune globulin (IG) products (RI-002, RI-001) have been designed to provide protection against respiratory syncytial virus (RSV) mediated respiratory illness while at the same time meeting the manufacturing requirements established by FDA for antibody supplementation in immunocompromised subjects. Areas covered: This review covers the manufacture and development of both RI-001 and RI-002, including the selection of plasma donors for IG preparation with high-titers of anti-RSV antibody, in vitro, and preclinical data in the cotton rat model S. hispidus, and clinical trials including Phase II and compassionate use studies of RI-001 and a multi-center, pivotal Phase III study of RI-002 in PIDD patients. Expert commentary: The data demonstrate that RI-002 is efficacious in the prevention and treatment of RSV in preclinical normal and immune suppressed animal models and is safe and efficacious in the treatment of patients with various forms of primary immunodeficiency disease (PIDD). This product offers potential advantages over other available IG's for prophylaxis in immunocompromised patients requiring polyclonal immunoglobulin supplementation because of its unique antibody composition. In addition to its enhanced neutralizing anti-RSV activity and its polyclonal IG composition, there is preclinical data to support the use of RI-002 for humoral protection against other respiratory pathogens.

    We developed a novel miniaturized and multiplexed, on-capillary, refractive index (RI) detector using liquid core optical ring resonators (LCORRs) for future development of capillary electrophoresis (CE) devices. The LCORR employs a glass capillary with a diameter of approximately 100 mum and a wall thickness of a few micrometers. The circular cross section of the capillary forms a ring resonator along which the light circulates in the form of the whispering gallery modes (WGMs). The WGM has an evanescent field extending into the capillary core and responds to the RI change due to the analyte conducted in the capillary, thus permitting label-free measurement. The resonating nature of the WGM enables repetitive light-analyte interaction, significantly enhancing the LCORR sensitivity. This LCORR architecture achieves dual use of the capillary as a sensor head and a CE fluidic channel, allowing for integrated, multiplexed, and noninvasive on-capillary detection at any location along the capillary. In this work, we used electro-osmotic flow and glycerol as a model system to demonstrate the fluid transport capability of the LCORRs. In addition, we performed flow speed measurement on the LCORR to demonstrate its flow analysis capability. Finally, using the LCORR's label-free sensing mechanism, we accurately deduced the analyte concentration in real time at a given point on the capillary. A sensitivity of 20 nm/RIU (refractive index units) was observed, leading to an RI detection limit of 10-6 RIU. The LCORR marries photonic technology with microfluidics and enables rapid on-capillary sample analysis and flow profile monitoring. The investigation in this regard will open a door to novel high-throughput CE devices and lab-on-a-chip sensors in the future.

    RI-Biomics is a fusion technology in radiation felds for evaluating in-vivo dynamics such as absorption, distribution, metabolism and excretion (RI-ADME) of new drugs and materials using radioisotopes and quantitative evaluation of their effcacy. RI-Biomics information is being provided by RIBio-Info developed as information system for distributing its information and three requirements for improving RIBio-Info system have been derived through reviewing recent big data trends in this study. Three requirements are defined as resource, technology and manpower, and some reviews for applying big data in RIBio-In system are suggested. Fist, applicable external big data have to be obtained, second, some infrastructures for realizing applying big data to be expanded, and finally, data scientists able to analyze large scale of information to be trained. Therefore, an original technology driven to analyze for atypical and large scale of data can be created and this stated technology can contribute to obtain a basis to create a new value in RI-Biomics feld

    Full Text Available Although the efficacy of omalizumab has been clearly demonstrated in the treatment of chronic spontaneous urticaria (CSU, its mechanism of action, which results in improvement in CSU symptoms, is not entirely understood. This study investigated the effect of omalizumab on expression of the high-affinity IgE receptor (FcεRI on blood basophils from patients with active CSU, and its association with the clinical response. Patients exhibiting significant clinical improvement showed a sharp reduction in the levels of basophil FcεRI after 4 weeks, which was maintained throughout the total duration of the treatment. Such evolution was not observed in non-responder patients. Furthermore, non-responders showed significantly lower baseline levels of FcεRI than responders. Baseline basophil FcεRI expression was found to be a potential immunological predictor of response to omalizumab (100% sensitivity and 73.2% specificity. The results of this study contribute to our knowledge of the therapeutic benefit and mechanism of action of anti-IgE therapy in CSU.

    Full Text Available Background: TheRI-48 cued recall test was devised to discriminate between healthy elderly and patients with mild cognitive impairment who are at risk of developing Alzheimer’s disease (AD. However, no long-term follow-up studies have been conducted using this test. Methods: We analyzed the predictive power of the RI-48 test for determining the patients who will convert to AD dementia within the decade after testing. During 10 years, we followed up 40 non-demented patients who attended our Memory Clinic and underwent complete neuropsychological evaluation including the RI-48. Results: Of the 40 patients, 21 developed dementia (converters, CO and 19 remained stable patients (SP. Of the tests performed at inclusion, only the RI-48 (p Conclusion: The RI-48 had the best overall diagnostic accuracy at 5- and at 10-year follow-ups.

  19. Utilidad del índice HOMA-IR con una sola determinación de insulinemia para diagnosticar resistencia insulínica Usefulness of HOMA-IR index with an only insulinemia determination to diagnose an insulin resistance

    . Conclusiones: una sola determinación de insulinemia para estudiar el HOMA-IR es de utilidad en la práctica diaria, aunque resulta de mucha mayor precisión aplicar la fórmula original para una mejor reproducibilidad.Introduction: HOMA-IR index is a simple and not much invasive procedure allowing by a validated and well established formula to specify exactly a value expression of insulin resistance. To estimate the HOMA-IR index with an only numerical value of insulinemia could to present a greater variability, something that could be solved with at least the mean of three insulinemias, according to original formula. En some studies it is habitual to perform it with a single insulinemia determination. Thus, we conducted a study in patients presenting type 2 diabetes and to compare the results as regards the sensitivity and specificity with a single blood determination for insulinemia and glycemia. Objectives: to assess the sensitivity and specificity of each of insulinemia determinations performed each 5 min versus the mean of these determinations during the application of formula for HOMA-IR index. Methods: sixty patients diagnosed with type 2 diabetes attended in the Center for Diabetic Care of La Habana were studied. They had a diabetes course time lower than 5 years as average with predominance of body excess weight recruited during 6 months in a consecutive way and the carrying out of fasting insulinemias and glycemias determinations by trocar and venous blood extraction at 0,5 and 10 min for a calculation of Mathews's hemostatic model known as HOMA-IR. Results: a 88,3 % had a HOMA-IR greater than 3,2. The sensitivity of a single sample of insulinemia, although high to confirm the insulin resistance diagnosis, it is variable and specificity of one of samples was low with a 14%. There is an appropriate concordance among the positive predictor values with sensitivity and the negative predictive values with the test specificity. Conclusions: a single insulinemia

    Full Text Available The purpose of this article is to analyze the connections of spatial relations and settings with narrative, and the presentation of these relations in Jüri Ehlvest’s texts. Distinctions are made between textual space (as designation, description, or rhetorical presentation and fictional space (the space in which narrative action takes place and the site of the denouement of events. Fictional space can be expressed as textual space in one of the four following ways: (a perceived space (b experienced space (c logical space (d alogical space. The multilayeredness of Ehlvest’s texts, their fragmentariness and dislocated reality, entail a complicated reception. In contrast, however, the geographical space represented in the texts is generally quite clear and accessible, with the effect of seeming real and humanly possible. Indeed, specific spatial elements are one of the sources of the verisimilitude and plausibility of Ehlvest’s texts. For the most part, the place where ehlvestian narrative plays itself out is a clear topographical environment, usually an interior; the textual representation of spaces is minimalist, avoiding descriptions, and with practically no impression of movement. In addition to representation of places, rooms, houses, and open space using ordinary, direct, (yet very minimalist means, several more indirect strategies of creating space can be found in Ehlvest’s texts. This article calls attention to some characteristic devices from this indirect repertoire, grouping them as follows: things; window and picture; repetition, fragment, and mirror; body and emptiness. Of the four types of textual space mentioned above, the one most characteristic of Ehlvest’s stories is experienced space, which could also be described as haptic space of experience. However, due to the fragmentariness and bricolage typical of Ehlvest, there are certainly also plenty of examples of the other types, particularly perceived and alogical space
