    Two kinds of lead-free solders, Sn-8Zn-3Bi and Sn-9Zn-lAl, were used to mount passive components onto printed circuit boards via a re-flow soldering process. The samples were stored at 150 deg. C for 200, 400, 600, 800, and 1100 h. The microstructures of the samples after aged at 150 deg. C for various times were characterized using optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS) and the analyzed of solder joint shear strengths. The joint strength between Sn-8Zn-3Bi and Cu pad was about 4.0 ± 0.3 kg, while the strength between Sn-9Zn-lAl and Cu pad had values of 2.6 ± 0.1 kg. Both kinds of solder joints exhibited reduced strengths with increasing aging times. After aging at 150 deg. C for 1100 h, the joints strengths of Sn-8Zn-3Bi and Sn-9Zn-lAl were 1.8 ± 0.3 and 1.7 ± 0.3 kg, respectively. Both the Sn-8Zn-3Bi and Sn-9Zn-lAl joints showed brittle fracture behaviors. A flat layer of Cu 5 Zn 8 intermetallic compound (IMC) was formed between Sn-8Zn-3Bi solder and Cu pad after reflow. When the aging time was increased to 400 h, Zn-depletion and formation of Cu 6 Sn 5 IMC were observed in the solders due to the interaction between the tin and zinc compounds. The interaction between Sn-9Zn-lAl solder and Cu pad had similar behavior, however, Cu 6 Sn 5 IMC formed in Sn-9Zn-lAl solder when after aging at 150 deg. C for 600 h. As the aging time increased, both types of solders generated clear IMC spalling layers with large and continuous voids. Those voids substantially decreased the joint strength

    Full Text Available Complement is one of the most important parts of the innate immune system. Some bacteria can gain resistance against the bactericidal action of complement by decorating their outer cell surface with lipopolysaccharides (LPSs containing a very long O-antigen or with specific outer membrane proteins. Additionally, the presence of sialic acid in the LPS molecules can provide a level of protection for bacteria, likening them to human cells, a phenomenon known as molecular mimicry. Salmonella O48, which contains sialic acid in the O-antigen, is the major cause of reptile-associated salmonellosis, a worldwide public health problem. In this study, we tested the effect of prolonged exposure to human serum on strains from Salmonella serogroup O48, specifically on the O-antigen length. After multiple passages in serum, three out of four tested strains became resistant to serum action. The gas-liquid chromatography/tandem mass spectrometry analysis showed that, for most of the strains, the average length of the LPS O-antigen increased. Thus, we have discovered a link between the resistance of bacterial cells to serum and the elongation of the LPS O-antigen.

    Urine is a clinical specimen often used in medical diagnostics for monitoring of elements concentrations and kidneys function. We determined the contents of magnesium (Mg), calcium (Ca), zinc (Zn), copper (Cu), iron (Fe), lead (Pb), and cadmium (Cd) in 74 samples of 24-h urine (from 46 women and 28 men). The measurements were realized by the atomic absorption spectrometry (AAS) with atomization in the flame (FAAS) and in the graphite furnace (GFAAS). The received results were the subject of statistical analysis including the sex and age of volunteers. Moreover, correlations between the elements and the relationships between age and amounts of excreted elements with urine were tested. We found the statistically significant higher content of Zn in men's urine than in women(')s one. Moreover, both adult women and men (>18 years) excreted much more Ca in urine in comparison to young subjects. Only in case of Pb the significant positive correlation between its amount in 24-h urine of all donors and age was stated. The correlation analysis has shown the significant positive relationships between Ca-Mg, Ca-Fe, Mg-Fe, Cu-Fe, Cu-Cd, Fe-Cd, and Pb-Cd in total samples of urine. Basing on our results, we concluded that the gender and age of donors may impact on the elemental status of 24-h urine.

    POEMS (Polyneuropathy, Organomegaly, Endocrinopathy, M protein, and Skin changes) syndrome is a complicated and rare disease. Systematic research on computed tomography (CT) imaging characteristics in POEMS syndrome is scanty. The role of CT in diagnosis needs to be assessed. To retrospectively analyze the CT imaging features in 24 patients with POEMS syndrome and evaluate the role of CT in diagnosis of this disease. Twenty-four patients with confirmed POEMS syndrome were included in the study. Chest and abdominal CT images were analyzed. The three minor diagnostic criteria for POEMS syndrome (extravascular volume overload, organomegaly, and bone lesions) can be detected effectively by CT. Extravascular volume overload involved multiple serous cavities: hydrothorax, hydropericardium, and ascites, which were found in 79.2%, 41.7%, and 54.2% patients, respectively. The volume of effusion was small to moderate. Organomegaly involved multiorgans: hepatomegaly was found in 45.8% patients, splenomegaly in 54.2%, and lymphadenopathy in 75% patients. Hepatospleen exhibited moderate homogeneous enlargement without local enhanced signal after injection of contrast material. Bone lesions were classified into three groups: osteosclerotic, osteolytic, and mixed lesions. Osteosclerotic lesions, taking multiple, scattered, and variably sized high-density plaque-like appearance, were found in 20.8% patients. Osteolytic lesions, exhibiting punched-out low-density image, were found in 4.2% patients. Mixed ones, holding both common characteristics of them, were detected in 8.3% patients. These CT abnormalities disappeared after effective treatment. CT plays vital role in the confirmation of the three minor diagnostic criteria for POEMS syndrome: extravascular volume overload, organomegaly, and bone lesions. © The Foundation Acta Radiologica 2015.

    Full Text Available Patterns of the maximum rainfall amounts registered in 24 hours within the Oltenia Plain. The present study aims at rendering the main features of the maximum rainfall amounts registered in 24 h within the Oltenia Plain. We used 30-year time series (1980-2009 for seven meteorological stations. Generally, the maximum amounts in 24 h display the same pattern as the monthly mean amounts, namely higher values in the interval May-October. In terms of mean values, the highest amounts are registered in the western and northern extremity of the plain. The maximum values generally exceed 70 mm at all meteorological stations: D.T. Severin, 224 mm, July 1999; Slatina, 104.8 mm, August 2002; Caracal, 92.2 m, July 1991; Bechet, 80.8 mm, July 2006; Craiova, 77.6 mm, April 2003. During the cold season, there was noticed a greater uniformity all over the plain, due to the cyclonic origin of rainfalls compared to the warm season, when thermal convection is quite active and it triggers local showers. In order to better emphasize the peculiarities of this parameter, we have calculated the frequency on different value classes (eight classes, as well as the probability of appearance of different amounts. Thus, it resulted that the highest frequency (25-35% is held by the first two classes of values (0-10 mm; 10.1-20 mm. The lowest frequency is registered in case of the amounts of more than 100 mm, which generally display a probability of occurrence of less than 1% and only in the western and eastern extremities of the plain.

    Reference intervals for many laboratory parameters determined in 24-h urine collections are either not publicly available or based on small numbers, not sex specific or not from a representative sample. Osmolality and concentrations or enzymatic activities of sodium, potassium, chloride, glucose, creatinine, citrate, cortisol, pancreatic α-amylase, total protein, albumin, transferrin, immunoglobulin G, α1-microglobulin, α2-macroglobulin, as well as porphyrins and their precursors (δ-aminolevulinic acid and porphobilinogen) were determined in 241 24-h urine samples of a population-based cohort of asymptomatic adults (121 men and 120 women). For 16 of these 24 parameters creatinine-normalized ratios were calculated based on 24-h urine creatinine. The reference intervals for these parameters were calculated according to the CLSI C28-A3 statistical guidelines. By contrast to most published reference intervals, which do not stratify for sex, reference intervals of 12 of 24 laboratory parameters in 24-h urine collections and of eight of 16 parameters as creatinine-normalized ratios differed significantly between men and women. For six parameters calculated as 24-h urine excretion and four parameters calculated as creatinine-normalized ratios no reference intervals had been published before. For some parameters we found significant and relevant deviations from previously reported reference intervals, most notably for 24-h urine cortisol in women. Ten 24-h urine parameters showed weak or moderate sex-specific correlations with age. By applying up-to-date analytical methods and clinical chemistry analyzers to 24-h urine collections from a large population-based cohort we provide as yet the most comprehensive set of sex-specific reference intervals calculated according to CLSI guidelines for parameters determined in 24-h urine collections.

  14. The art of staying tuned in real-time. Remediation in 24.

    Full Text Available This article examines and discusses current media strategies in 24 Hours. Elements from interface design, computer games, canonized TV-series, reality-TV, on-line multiplayer games, fandom on the web, etc. are all part of the implicit as well as explicit familiarity and subject matter of 24. Thus, 24 becomes a unique case in point of present day remediation and transmediation. While the former plots the actualisation of historic media into contemporary hybrid genres and expressions, the latter paws the way for media forms that continuously and rapidly communicate with each other. Hereby, the study of 24 calls for new and flexible analytical tools and readings of cultural consumption. In addition, the article investigates how such apparently abstract concepts like contingency, conspiracy, and temporality are dramatized in Fox Network's 24.

    The giant-resonance region of 24 Mg, 27 Al, and 28 Si was studied by inelastic scattering of 126-MeV α particles. In contrast to results at 96 MeV, considerable clustering of E2 strength was observed for 27 Al at E/sub x/ approx. 20.1 MeV with GAMMA approx. 7.6 MeV exhausting about 35% of the E2 energy weighted sum rule. E2 strength was also located in 24 Mg in two clusters of states at E-bar/sub x/ approx. 18.2, 24.4 MeV; however, contributions from other multipoles cannot be neglected. In 28 Si a multipeaked group was observed at E/sub x/ approx. 19.4 MeV with GAMMA approx. 4 MeV but no L assignment was made. The energy dependence of the cross section for the giant quadrupole resonance was found to be consistent with distorted-wave Born approximation predictions

    The JPL Airborne Snow Observatory (ASO) must process 100s of GB of raw data to 100s of Terabytes of derived data in 24 hour Near Real Time (NRT) latency in a geographically distributed mobile compute and data-intensive processing setting. ASO provides meaningful information to water resource managers in the Western US letting them know how much water to maintain; or release, and what the prospectus of the current snow season is in the Sierra Nevadas. Providing decision support products processed from airborne data in a 24 hour timeframe is an emergent field and required the team to develop a novel solution as this process is typically done over months. We've constructed a system that combines Apache OODT; with Apache Tika; with the Interactive Data Analysis (IDL)/ENVI programming environment to rapidly and unobtrusively generate, distribute and archive ASO data as soon as the plane lands near Mammoth Lakes, CA. Our system is flexible, underwent several redeployments and reconfigurations, and delivered this critical information to stakeholders during the recent "Snow On" campaign March 2013 - June 2013. This talk will take you through a day in the life of the compute team from data acquisition, delivery, processing, and dissemination. Within this context, we will discuss the architecture of ASO; the open source software we used; the data we stored; and how it was delivered to its users. Moreover we will discuss the logistics, system engineering, and staffing that went into the developing, deployment, and operation of the mobile compute system.

    Grab water samples, sediment samples, and 2,2,4-trimethylpentane passive samplers (TRIMPS) were used to determine the exposure to 97 pesticides in 24 southeast Australian stream sites over 5 months. Macroinvertebrate communities and selected microorganisms (bacteria, flagellates, ciliates, amoebas, nematodes, and gastrotrichs) were sampled to detect relationships with pesticide toxicity. Sediment samples had the highest estimated toxicities in terms of toxic units (TU) for Daphnia magna (TUDM) and for Selenastrum capricornutum (TUSC). The pesticide-selective SPEARpesticides and the general SIGNAL index for macroinvertebrates exhibited negative linear relationships (r(2) = 0.67 and 0.36, respectively) with pesticide contamination in terms of log maximum TUDM (log mTUDM), suggesting macroinvertebrate community change due to pesticide exposure. Pesticide contamination was the only measured variable explaining variation in ecological quality. Variation in the densities of several microbial groups was best explained by environmental variables other than log TUs. The log mTUDM values derived from sediment concentrations were most important to establish a link with effects on macroinvertebrates, whereas log mTUDM of grab water samples had only minor contribution. Current-use insecticides and fungicides can affect macroinvertebrate communities and monitoring of sediment and continuous water sampling is needed to detect these effects.

    Blood pressure variability (BPV) has been associated with increased morbidity and mortality. There are a few studies that reported worse outcomes of chronic kidney disease (CKD) with greater visit-to-visit BPV (VVV), but data with ambulatory blood pressure monitoring (ABPM) is scarce. Ambulatory hypertensive CKD (stage 2 - 4) patients (> 18 years old) with complete 24 hours of ABPM study (SpaceLabs), who were followed up between January 2012 and December 2016, were retrospectively analyzed for the baseline characteristics and outcomes of CKD. Coefficient of variation (CV) in diastolic blood pressure (DBP) was used as an index of BPV. Data of 191 patients (mean age 59.7 ± 12.4 years, 54.9% males, 42.1% diabetic, mean eGFR-EPI (Chronic Kidney Disease Epidemiology Collaboration) 51.7 ± 22.0 mL/min/1.73m2, mean follow-up 26.2 ± 10.4 months) were available for the analysis. On multivariate linear regression analysis, greater DBP-CV was associated with slower decline in eGFR-EPI per year (B -0.648, p = 0.000). Likewise, the hazard ratio (HR) for dialysis inception (occurred in 9.4%) was found significantly lower with increasing DBP-CV in unadjusted and fully adjusted Cox models (HR 0.730, 95% CI 0.618 - 0.861, p = 0.000, and HR 0.678, 95% CI 0.526 - 0.874, p = 0.003, respectively). These findings suggest that DBP variability in 24-hour ABPM may be a good prognostic factor for the outcomes of CKD. Further studies are needed to determine the impact of 24-hour ABPM BPV on CKD progression and its differences from VVV.

    To compare the pharmacokinetics after po different doses of beta-carboxyethylgermanium sesquioxide (Ge-132). An atomic absorption spectrophotometric system was used to measure germanium concentrations in plasma and urine samples after po Ge-132 1 (low dose, LD), 2.5 (medium dose, MD), and 4 (high dose, HD) g.m-2 in 24 healthy volunteers (one dose per 8 subjects). T1/2 alpha (LD, 1.2 +/- 0.7 h; MD, 1.1 +/- 0.6 h; HD, 1.2 +/- 0.5 h), T1/2 beta (LD, 5.2 +/- 1.2 h; MD, 5.8 +/- 2.5 h; HD, 5.5 +/- 1.4 h) and Cl/F (LD, 33 +/- 12 L.h-1; MD, 35 +/- 10 L.h-1; HD, 33 +/- 11 L.h-1) were not dose-related. Tmax was between 0.75 h and 2 h. Cmax (LD, 5.3 +/- 2.2 mg.L-1; MD, 13 +/- 5 mg.L-1; HD 18 +/- 8 mg.L-1, HD) and AUC (LD, 31 +/- 13 mg.h.L-1; MD, 60 +/- 16 mg.h.L-1; HD, 79 +/- 42 mg.h.L-1) were positive correlation to the dose of Ge-132. Urine-eliminated germanium within 24 h accounted for 11 +/- 3% of LD, 9 +/- 3% of MD, and 6 +/- 5% of HD (calculated from Ge/F) and showed a negative correlation to the dose. 1) Intracorporal process of Ge after po Ge-132 coincided with the first-order absorption and elimination with two-compartment kinetic model; 2) The amount of germanium eliminated in urine was below 11%.

  20. Difference in 24-Hour Urine Composition between Diabetic and Non-Diabetic Adults without Nephrolithiasis.

    Full Text Available Diabetic patients are more likely to develop kidney stones than the general population. The underlying mechanisms for this disparity remain to be elucidated. Little is known about the relationship between urine composition and diabetes mellitus in non-stone-forming individuals. We sought to examine the differences in the 24-hour (24-h urine composition between diabetic and non-diabetic adults who were not stone formers.A convenience sample of 538 individuals without a history of nephrolithiasis, gout, hyperparathyroidism, or gastroenteric diseases participated in this study. The 24-h urine profiles of 115 diabetic adults were compared with those of 423 non-diabetic adults. Diabetes was defined by self-reported physician diagnosis or medication use. All participants were non-stone formers confirmed by urinary tract ultrasonography. Participants provided a fasting blood sample and a single 24-h urine collection for stone risk analysis. Student's t-test was used to compare mean urinary values. Linear regression models were adjusted for age, gender, body mass index, hypertension, fasting serum glucose, serum total cholesterol, estimated creatinine clearance rate and urinary factors.Univariable analysis showed that the diabetic participants had significantly higher 24-h urine volumes and lower urine calcium and magnesium excretions than non-diabetic participants (all P 0.05. The main limitation of this study is that the convenience samples and self-reported data may have been sources of bias.Our data showed that there were no differences in 24-h urine composition between diabetic and non-diabetic adults who are not stone formers. The reason for it might be the improved glycemic control in diabetic individuals in our study. Therefore, a tighter glycemic control might reduce stone formation in diabetic adults.

    Retrospective study. To determine whether pediatric patients undergo additional airport security screening after posterior spinal fusion. Airport security has expanded to include body scanners as well as traditional metal detectors. Families frequently ask whether spinal implants will trigger airport security, but there is limited information on modern implants and screening methods. The researchers conducted a survey of 50 pediatric patients after posterior spinal fusion from 2004 to 2013. Inclusion criteria were posterior instrumentation, pedicle screws for at least 80% of anchors, and at least 1 trip through an American airport after surgery. Charts and radiographs were reviewed for metal type, number of levels fused, number of anchors, and rod diameter. A total of 16% of patients (8 of 50) were detected by body scan or metal detector and all had cobalt chrome (CoCr) rods. No patients with stainless-steel (SS) rods were detected. The CoCr rods triggered additional screening in 24% of children (8 of 33), compared with none of 17 with SS rods (p = .03). For patients with CoCr rods, the detection rate was 18% (5 of 28) by metal detector and 17% (3 of 18) by body scanner. For patients with CoCr rods, there was no significant difference between detection rates and levels fused (p = .30), number of anchors (p = .15), or rod diameter (p = .17). In this series, CoCr constructs were more likely to incur additional airport security compared with more traditional SS constructs. Copyright © 2015 Scoliosis Research Society.

    Parabens are widely used as antimicrobial preservatives in personal care and consumer products, food and pharmaceuticals. Due to their ubiquity, humans are constantly exposed to these chemicals. We assessed exposure to nine parabens (methyl-, ethyl-, n- and iso-propyl-, n- and iso-butyl-, benzyl-, pentyl- and heptyl paraben) in the German population from 1995 to 2012 based on 660 24h urine samples from the German Environmental Specimen Bank (ESB) using on-line HPLC coupled to isotope dilution tandem mass spectrometry. The limit of quantification (LOQ) was 0.5 μg/L for all parabens. We detected methyl-, ethyl- and n-propyl paraben in 79-99% of samples, followed by n-butyl paraben in 40% of samples. We infrequently detected iso-butyl-, iso-propyl- and benzyl paraben in 24%, 4% and 1.4% of samples, respectively. Urinary concentrations were highest for methyl paraben (median 39.8 μg/L; 95th percentile 319 μg/L) followed by n-propyl paraben (4.8 μg/L; 95th percentile 74.0 μg/L) and ethyl paraben (2.1 μg/L; 95th percentile 39.1 μg/L). Women had significantly higher urinary levels for all parabens than men, except for benzyl paraben. Samples from the ESB revealed that over the investigation period of nearly 20 years urinary paraben levels remained surprisingly constant; only methyl paraben had a significant increase, for both men and women. We found strong correlations between methyl- and n-propyl paraben and between n- and iso-butyl paraben. These results indicate that parabens are used in combination and arise from common sources of exposure. Urinary excretion factors are needed to extrapolate from individual urinary concentrations to actual doses. Copyright © 2015 Elsevier GmbH. All rights reserved.

    There is growing interest in designing cities that support not only walking, but also cycling. Bike Score® is a metric capturing environmental characteristics associated with cycling that is now available for over 160 US and Canadian cities. Our aim was to determine if Bike Score was associated with between and within-city variability in cycling behavior. We used linear regression to model associations between Bike Score and journey to work cycling mode share (US: American Community Survey, 2013 or 2012 5-year estimates; Canada: 2011 National Household Survey) for 5664 census tracts in 24 US and Canadian cities. At the city level, the correlation between mean Bike Score and mean journey to work cycling mode share was moderate (r = 0.52). At the census tract level, the correlation was 0.35; a ten-unit increase in Bike Score was associated with a 0.5% (95% CI: 0.5 to 0.6) increase in the proportion of population cycling to work, a meaningful difference given the low modal shares (mean = 1.9%) in many North American cities. Census tracts with the highest Bike Scores (>90 to 100) had mode shares 4.0 higher (β = 4.0, 95% CI: 2.9 to 5.0) than the lowest Bike Score areas (0-25). City specific analyses indicated between-city variability in associations, with regression estimates between Bike Score and mode share ranging from 0.2 to 3.5%. The Bike Score metric was associated bicycle mode share between and within cities, suggesting its utility for planning bicycle infrastructure.

    Aim: To evaluate the efficacy and safety of renal artery embolisation (RAE) for renal arteriovenous malformation (AVM) as well as its outcomes. Materials and methods: The technical and clinical success rates, radiological and laboratory findings, and complications of RAE for 31 renal AVMs in 24 patients (M:F=9:15, mean age 46 years) at two separate medical institutions were retrospectively evaluated. Technical success was defined as complete occlusion of feeding arteries with no residual nidus seen on post-treatment angiography. Clinical failure was defined as recurrence of haematuria, presence of AVM on follow-up ultrasound or computed tomography, repeated RAE or surgery for the control of haematuria. Overall clinical success was defined as resolution haematuria or disappearance of AVM on follow-up imaging after single or multiple sessions of RAE. Results: Types of renal AVM were AVM, arterio-venous fistula (AVF) with intranidal aneurysm, and acquired AVF in 19, 1, and 4 patients, respectively. 18 patients (75%) underwent a single session of RAE, while 6 patients (25%) had two or more sessions of RAE. The level of embolisation was feeder, segmental artery, and main renal artery in 28 (90%), 2 (6%), and 1 (4%) procedures, respectively. Coil, n-butyl 2-cyanoacrylate, and polyvinyl alcohol were the most frequently chosen embolic materials and were used in 19, 14, and 8 procedures, respectively. The clinical success rate after initial RAE was 67% (16/24). Overall clinical success rate, including multisession RAE, was 88% (21/24). The technical success rate of 31 procedures was 65% (20/31). Among 11 technical failures in 10 patients, 4 achieved clinical success without additional RAE, 3 underwent second session RAE to achieve clinical success, and 3 patients underwent nephrectomy due to recurrence. Conclusion: RAE is a safe and effective treatment for renal AVM. Technical failure of RAE does not always lead to clinical failure and multiple embolisation sessions may be

    Today’s high performance green homes are reaching previously unheard of levels of airtightness and are using new materials, technologies and strategies, whose impacts on Indoor Air Quality (IAQ) cannot be fully anticipated from prior studies. This research study used pollutant measurements, home inspections, diagnostic testing and occupant surveys to assess IAQ in 24 new or deeply retrofitted homes designed to be high performance green buildings in California. Although the mechanically vented homes were six times as airtight as non-mechanically ventilated homes (medians of 1.1 and 6.1 ACH50, n=11 and n=8, respectively), their use of mechanical ventilation systems and possibly window operation meant their median air exchange rates were almost the same (0.30 versus 0.32 hr-1, n=8 and n=8, respectively). Pollutant levels were also similar in vented and unvented homes. In addition, these similarities were achieved despite numerous observed faults in complex mechanical ventilation systems. More rigorous commissioning is still recommended. Cooking exhaust systems were used inconsistently and several suffered from design flaws. Failure to follow best practices led to IAQ problems in some cases. Ambient nitrogen dioxide standards were exceeded or nearly so in four homes that either used gas ranges with standing pilots, or in Passive House-style homes that used gas cooking burners without venting range hoods. Homes without active particle filtration had particle count concentrations approximately double those in homes with enhanced filtration. The majority of homes reported using low-emitting materials; consistent with this, formaldehyde levels were approximately half those in conventional, new CA homes built before 2008. Emissions of ultrafine particles (with diameters <100 nm) were dramatically lower on induction electric cooktops, compared with either gas or resistance electric models. These results indicate that high performance homes can achieve

    To examine possible gender-specific differences in 24-hr outcome following resuscitation from 9 mins of controlled cardiac arrest. Preclinical, prospective study comparing two similarly prepared, independent control groups (one female group, one male group) included in a larger series of studies. Physiology research laboratory at a major medical center. Male and female mongrel dogs (Canis familiaris), weighing 16 to 22 kg. Cardiopulmonary-cerebral resuscitation following 9 mins of normothermic cardiac arrest in male vs. female dogs. Mean arterial blood pressure, heart rate, urine output, arterial blood oxygen, and PCO2 values, arterial pH, temperature, plasma glucose concentrations, and hematocrit were measured and recorded at the precardiac arrest and postcardiac arrest period, and at 30 mins, and 1, 4, 6, 12, and 24 hrs following resuscitation. Neurologic dysfunction was assessed using a well-standardized neurologic deficit score assigned at 6, 12, and 24 hrs after arrest. Plasma concentrations of malonaldehyde, 4-hydroxynonenal, and erythrocyte-reduced glutathione were measured at the precardiac arrest period, and 6, 12, and 24 hrs following resuscitation. Additionally, serum concentrations of alanine aminotransferase, aspartate aminotransferase, total bilirubin, alkaline phosphatase, gamma-glutamyl transferase, creatinine kinase, creatinine, albumin, and total protein were measured before arrest, and at 6, 12, and 24 hrs after resuscitation. Plasma concentrations of inorganic phosphorus, blood urea nitrogen, and electrolytes (sodium, chloride, calcium, and potassium) were measured. The estrous cycle phase in the female dogs enrolled in the study was determined by physical examination and vaginal cytology. No prearrest differences were detectable between males and females in basic physiologic variables. No differences in neurologic deficit were detectable between males and females across the 24-hr recovery period following resuscitation. No detectable

    Extreme fire seasons have become common in western North America, and the extent of young postfire forests has grown as fire frequency and annual area burned have increased. These young forests will set the stage for future fires, but an assessment of fuel loads in young forests is lacking. The rate of fuel re-accumulation and fuels variability in postfire forest landscapes is needed to anticipate future fire occurrence and behavior in the American West. We studied fuel characteristics in young lodgepole pine forests that regenerated after the 1988 fires in Yellowstone National Park to address two questions: (1) How do surface fuel characteristics change with time-since-fire? (2) How do canopy and surface fuels vary across the Yellowstone landscape 24 years postfire? During summer 2012, we re-measured surface fuels in 11 plots that were established in 1996 (8 yrs post fire), and we measured surface and canopy fuels in 82 stands (each 0.25 ha) distributed across the Yellowstone post-1988 fire landscape. In the remeasured plots, surface fuel loads generally increased over the last 16 years. One-hr fuels did not change between sample dates, but all other fuel classes (i.e., 10-hr, 100-hr, and 1000-hr) increased by a factor of two or three. Within the sample timeframe, variability of fuel loads within stands decreased significantly. The coefficients of variation decreased for all fuel classes by 23% to 67%. Data from the 82 plots revealed that canopy and surface fuels in 24-year-old stands varied tremendously across the Yellowstone landscape. Live tree densities spanned 0 to 344,067 trees ha-1, producing a mean available canopy fuel load of 7.7 Mg ha-1 and a wide range from 0 to 47 Mg ha-1. Total surface fuel loads averaged 130 Mg ha-1 and ranged from 49 to 229 Mg ha-1, of which 90% was in the 1000-hr fuel class. The mass of fine surface fuels (i.e., litter/duff, 1-hr, 10-hr, and herbaceous fuels) and canopy fuels (i.e., foliage and 1-hr branches) were strongly and

    Full Text Available OBJECTIVES: This study examined the changes in running performance and the sex differences between women and men in 24-hour ultra-marathons held worldwide from 1977 to 2012. METHOD: Changes in running speed and ages of the fastest 24-hour ultra-marathoners were determined using single- and multi-level regression analyses. RESULTS: From 1977 to 2012, the sex differences in 24-hour ultra-marathon performance were 4.6±0.5% for all women and men, 13.3% for the annual fastest finishers, 12.9±0.8% for the top 10 and 12.2±0.4% for the top 100 finishers. Over time, the sex differences decreased for the annual fastest finishers to 17%, for the annual 10 fastest finishers to 11.3±2.2% and for the annual 100 fastest finishers to 14.2±1.8%. For the annual fastest men, the age of peak running speed increased from 23 years (1977 to 53 years (2012. For the annual 10 and 100 fastest men, the ages of peak running speed were unchanged at 40.9±2.5 and 44.4±1.1 years, respectively. For women, the ages of the annual fastest, the annual 10 fastest and the annual 100 fastest remained unchanged at 43.0±6.1, 43.2±2.6 and 43.8±0.8 years, respectively. CONCLUSION: The gap between the annual top, annual top 10 and annual top 100 female and male 24-hour ultra-marathoners decreased over the last 35 years; however, it seems unlikely that women will outrun men in 24-hour ultra-marathons in the near future. The fastest 24-hour ultra-marathoners worldwide achieved their peak performance at the age of master athletes (>35 years.

    The 24-h urine sample is considered as the most reliable material for testing many but not necessarily all constituents in urine. However, its collection is tedious for both patients and research participants. The aim of this study was to compare concentrations of essential elements calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), and zinc (Zn) in 24-h and spot urine samples. Urine samples were collected from 143 generally healthy women, aged 30-79 years. Fasting spot urine was collected immediately after the end of the 24-h collection, therefore being of the same content as the first morning urine which ended the 24-h collection. Elements were analyzed by flame atomic absorption/emission spectrometry and expressed as mg/g and/or mmol/mol of creatinine (Cr). Spearman rank order correlations between 24-h and spot urine were carried out for each element. Ratios of elements in 24-h to spot urine samples were calculated to estimate the element-proportion of spot in the 24-h sample. All coefficients of correlation between 24-h and spot urine of measured elements and Cr were significant (purine samples for each element (except K) were similar and close to 2, indicating uniform proportion of elements from spot urine sample in the 24-h sample. In addition, a high correlation between various pairs of elements was obtained in both 24-h and spot urine; the highest being between Na/Ca (0.435) and (0.578), respectively. This is in accordance with theoretical presumptions and previous findings regarding those relationships. Although replacing burdensome 24-h urine collection with spot urine sampling might not provide the solution in all cases, our results show that for the elements analyzed, spot urine could be a reliable alternative.

    This study complements existing literature by examining the nexus between energy consumption (EC), CO2 emissions (CE), and economic growth (GDP; gross domestic product) in 24 African countries using a panel autoregressive distributed lag (ARDL) approach. The following findings are established. First, there is a long-run relationship between EC, CE, and GDP. Second, a long-term effect from CE to GDP and EC is apparent, with reciprocal paths. Third, the error correction mechanisms are consistently stable. However, in cases of disequilibrium, only EC can be significantly adjusted to its long-run relationship. Fourth, there is a long-run causality running from GDP and CE to EC. Fifth, we find causality running from either CE or both CE and EC to GDP, and inverse causal paths are observable. Causality from EC to GDP is not strong, which supports the conservative hypothesis. Sixth, the causal direction from EC to GDP remains unobservable in the short term. By contrast, the opposite path is observable. There are also no short-run causalities from GDP, or EC, or EC, and GDP to EC. Policy implications are discussed.

    Full Text Available Koichi Nisijima, Katutoshi ShiodaDepartment of Psychiatry, Jichi Medical University, Tochigi, JapanAbstract: Neuroleptic malignant syndrome (NMS is a dangerous adverse response to antipsychotic drugs. It is characterized by the four major clinical symptoms of hyperthermia, severe muscle rigidity, autonomic dysfunction, and altered mental state. Serum creatine kinase (CK elevation occurs in over 90% of NMS cases. In the present study, the detailed temporal changes in serum CK and degree of muscle rigidity, and the relationship between CK concentration and degree of muscle rigidity over the time course from fever onset, were evaluated in 24 affected patients. The results showed that serum CK peaked on day 2 after onset of fever and returned to within normal limits at day 12. Mild muscle rigidity was observed before the onset of fever in 17 of 24 cases (71%. Muscle rigidity was gradually exacerbated and worsened until day 4 after onset of fever. These findings confirm physicians' empirical understanding of serum CK concentrations and muscle rigidity in NMS based on data accumulated from numerous patients with the syndrome, and they indicate that serum CK may contribute to the early detection of NMS.Keywords: neuroleptic malignant syndrome, creatine kinase, muscle rigidity

    Full Text Available One-neutron knockout from 24O leading to the first excited state in 23O has been measured for a proton target at a beam energy of 62 MeV/nucleon. The decay energy spectrum of the neutron unbound state of 23O was reconstructed from the measured four momenta of the 22O fragment and emitted neutron. A sharp peak was found at Edecay=50±3 keV, corresponding to an excited state in 23O at 2.78±0.11 MeV, as observed in previous measurements. The longitudinal momentum distribution for this state was consistent with d-wave neutron knockout, providing support for a Jπ assignment of 5/2+. The associated spectroscopic factor was deduced to be C2S(0d5/2=4.1±0.4 by comparing the measured cross section (σ−1nexp=61±6 mb with a distorted wave impulse approximation calculation. Such a large occupancy for the neutron 0d5/2 orbital is in line with the N=16 shell closure in 24O.

    Several genetic causes of ectopia lentis (EL), with or without systemic features, are known. The differentiation between syndromic and isolated EL is crucial for further treatment, surveillance and counseling of patients and their relatives. Next generation sequencing (NGS) is a powerful tool enabling the simultaneous, highly-sensitive analysis of multiple target genes. The aim of this study was to evaluate the diagnostic yield of our NGS panel in EL patients. Furthermore, we provide an overview of currently described mutations in ADAMTSL4, the main gene involved in isolated EL. A NGS gene panel was analysed in 24 patients with EL. A genetic diagnosis was confirmed in 16 patients (67%). Of these, four (25%) had a heterozygous FBN1 mutation, 12 (75%) were homozygous or compound heterozygous for ADAMTSL4 mutations. The known European ADAMTSL4 founder mutation c.767_786del was most frequently detected. The diagnostic yield of our NGS panel was high. Causative mutations were exclusively identified in ADAMTSL4 and FBN1. With this approach the risk of misdiagnosis or delayed diagnosis can be reduced. The value and clinical implications of establishing a genetic diagnosis in patients with EL is corroborated by the description of two patients with an unexpected underlying genetic condition.

    Reference methods for the quantification of the glomerular filtration rate (GFR) are difficult to use in clinical practice; formulas for evaluating GFR based on serum creatinine (SCr) and/or creatinine clearance are used. The aim of this study was to quantify the correlation and concordance of GFR with creatinine clearance in 24-hour urine (GFR24) and Schwartz and Schwartz updated formulas. Cross-sectional study involving healthy pediatric patients and with chronic kidney disease (CKD) from 5 to 16.9 years. Linear correlation between GFR 24 and two formulas was evaluated with the Pearson correlation coefficient (r) and intraclass correlation coefficient (ICC). We studied 134 patients, of which 59.7% were male. Mean age was 10.8 years. The average GFR24 was 140.34ml/min/1.73m 2 ; 34.3% (n=46) had GFR Schwartz (r= 0.63) and Schwartz updated (r= 0.65) formulas was observed. There was good concordance between the GFR24 and Schwartz (ICC= 0.77) and updated Schwartz (ICC= 0.77) formulas. Schwartz classical formula in patients with GFR24 ≥ 90ml/min/1.73m 2 estimated higher values, while Schwartz updated underestimated values. There is moderate correlation and good concordance between the GFR24 and Schwartz and Schwartz updated formulas. The concordance was better in patients with obesity and lower in women, patients with hyperfiltration and normal weight. Copyright © 2016 Hospital Infantil de México Federico Gómez.

    Sodium, potassium, calcium, magnesium, zinc, copper and iron are associated with the sequela of hypertension. The most reliable method for testing those elements is by collecting 24-h urine samples. However, this is cumbersome and collection of spot urine is more convenient in some circumstance. The aim of this study was to compare the concentrations of different elements in 24-h urine and spot urine. Data was collected from a sub-study of China Salt Substitute and Stroke Study. 240 participants were recruited randomly from 12 villages in two counties in Ningxia, China. Both spot and 24-h urine specimens were collected from each patient. Routine urine test was conducted, and concentration of elements was measured using microwave digestion and Inductively Coupled Plasma-Optical Emission Spectrometry. Partial correlation analysis and Spearman correlation analysis were used to investigate the concentration of different elements and the relationship between 24- h urine and spot urine. A partial correlation in sodium, potassium, calcium, magnesium and iron was found between paired 24-h urine and spot urine samples except copper and zinc: 0.430, 0.426, 0.550, 0.221 and 0.191 respectively. Spot urine can replace 24-h urine for estimating some of the elements in hypertensive patients with normal renal function. Copyright © 2017 Elsevier GmbH. All rights reserved.

    This study aims to (1) estimate the prevalence of acute respiratory infection (ARI) symptoms, diarrhoea and fever in the previous two weeks among 3-4 year old children who are/are not at-risk of intellectual disability in 24 low- and middle-income countries and (2) to investigate possible inequities in access to treatment among affected children. Cross-sectional survey. Secondary analysis of Rounds 4 and 5 UNICEF Multiple Indicator Cluster Surveys (MICS) from 24 low- and middle-income countries (n = 99,934 children). Pooled estimates indicated that young children at-risk of intellectual disability in low-income countries were significantly more likely than their peers to have reported symptoms of ARI and diarrhoea in the previous 2 weeks, and significantly less likely to have received appropriate treatment. Pooled estimates indicated that in middle-income countries children at-risk of intellectual disability were significantly more likely than their peers to have reported symptoms of ARI, diarrhoea and fever during the previous 2 weeks. Symptomatic children at-risk of intellectual disability were significantly less likely than their peers to have received antibiotics/antimotility medication for diarrhoea or antibiotics for ARI symptoms, but significantly more likely to be prescribed anti-malarials for fever. These results indicate the existence of significant inequalities and possible inequities in the exposure to and the treatment of three major infectious diseases among children who are/are not considered at-risk of intellectual disabilities in low- and middle-income countries.

    Escalating wildfire in subalpine forests with stand-replacing fire regimes is increasing the extent of early-seral forests throughout the western USA. Post-fire succession generates the fuel for future fires, but little is known about fuel loads and their variability in young post-fire stands. We sampled fuel profiles in 24-year-old post-fire lodgepole pine (Pinus contorta var. latifolia) stands (n = 82) that regenerated from the 1988 Yellowstone Fires to answer three questions. (1) How do canopy and surface fuel loads vary within and among young lodgepole pine stands? (2) How do canopy and surface fuels vary with pre- and post-fire lodgepole pine stand structure and environmental conditions? (3) How have surface fuels changed between eight and 24 years post-fire? Fuel complexes varied tremendously across the landscape despite having regenerated from the same fires. Available canopy fuel loads and canopy bulk density averaged 8.5 Mg/ha (range 0.0-46.6) and 0.24 kg/m 3 (range: 0.0-2.3), respectively, meeting or exceeding levels in mature lodgepole pine forests. Total surface-fuel loads averaged 123 Mg/ha (range: 43-207), and 88% was in the 1,000-h fuel class. Litter, 1-h, and 10-h surface fuel loads were lower than reported for mature lodgepole pine forests, and 1,000-h fuel loads were similar or greater. Among-plot variation was greater in canopy fuels than surface fuels, and within-plot variation was greater than among-plot variation for nearly all fuels. Post-fire lodgepole pine density was the strongest positive predictor of canopy and fine surface fuel loads. Pre-fire successional stage was the best predictor of 100-h and 1,000-h fuel loads in the post-fire stands and strongly influenced the size and proportion of sound logs (greater when late successional stands had burned) and rotten logs (greater when early successional stands had burned). Our data suggest that 76% of the young post-fire lodgepole pine forests have 1,000-h fuel loads that exceed levels

    The KL2,3 and L3M4,5 radiative resonant Raman scattering (RRS) cross sections have been measured for the quasimonochromatic Mn Kα1,2 X-rays (5.895 keV) in 24Cr (K-shell level width (ΓK) =1.08 eV) and 59 Pr (L3-subshell level width (ΓL3) =3.60 eV), respectively, using targets in metallic and various chemical forms. The incident Mn Kα1,2 X-ray energy is lower than the K-shell binding energy of 24Cr and L3-subshell binding energy of 59Pr by 94 ΓK (Cr) and 94 ΓL3 (Pr), respectively. The experimental measurements were performed with a low energy Ge detector (LEGe) and a radioactive 55Fe annular source in conjunction with 24Cr absorber. The measured cross section values for the 24Cr and 59 Pr elements in their various oxidation states are found to be same within experimental errors. The measurements were further extended to investigate alignment of the intermediate L3-subshell (J =3/2) virtual vacancy states in 59Pr through angular distribution measurements for RRS photon emission, which is found to be isotropic within experimental errors.

    Background: Acute exercise reduces postprandial oxidative stress and glycemia; however, the effects of exercise intensity are unclear. We investigated the effect of acute low-volume high-intensity interval-exercise (LV-HIIE) and continuous moderate-intensity exercise (CMIE) on glycemic control and oxidative stress in overweight and obese, inactive adults. Methods: Twenty-seven adults were randomly allocated to perform a single session of LV-HIIE (9 females, 5 males; age: 30 ± 1 years; BMI: 29 ± 1 kg·m -2 ; mean ± SEM) or CMIE (8 females, 5 males; age: 30 ± 2.0; BMI: 30 ± 2.0) 1 h after consumption of a standard breakfast. Plasma redox status, glucose and insulin were measured. Continuous glucose monitoring (CGM) was conducted during the 24-h period before (rest day) and after exercise (exercise day). Results: Plasma thiobarbituric acid reactive substances (TBARS; 29 ±13%, p improvement in 24-h average glucose levels (-5 ± 2%, p improving 24-h glycemic control in overweight and obese adults.

    Validation-study data were analyzed to investigate retention interval (RI) and prompt effects on accuracy of fourth-grade children’s reports of school-breakfast and school-lunch (in 24-hour recalls), and accuracy of school-breakfast reports by breakfast location (classroom; cafeteria). Randomly-selected fourth-grade children at 10 schools in four districts were observed eating school-provided breakfast and lunch, and interviewed under one of eight conditions (two RIs [short (prior-24-hour recall obtained in afternoon); long (previous-day recall obtained in morning)] crossed with four prompts [forward (distant-to-recent), meal-name (breakfast, etc.), open (no instructions), reverse (recent-to-distant)]). Each condition had 60 children (half girls). Of 480 children, 355 and 409 reported meals satisfying criteria for reports of school-breakfast and school-lunch, respectively. For breakfast and lunch separately, a conventional measure—report rate—and reporting-error-sensitive measures—correspondence rate and inflation ratio—were calculated for energy per meal-reporting child. Correspondence rate and inflation ratio—but not report rate—showed better accuracy for school-breakfast and school-lunch reports with the short than long RI; this pattern was not found for some prompts for each sex. Correspondence rate and inflation ratio showed better school-breakfast report accuracy for the classroom than cafeteria location for each prompt, but report rate showed the opposite. For each RI, correspondence rate and inflation ratio showed better accuracy for lunch than breakfast, but report rate showed the opposite. When choosing RI and prompts for recalls, researchers and practitioners should select short RIs to maximize accuracy. Recommendations for prompt selections are less clear. As report rates distort validation-study accuracy conclusions, reporting-error-sensitive measures are recommended. PMID:26865356

    The aim of the study is to assess the compliance rate of treatment of postpartum hemorrhage (PPH) according to guidelines developed by the CNGOF within our network by a first audit, and evaluate the impact of this first audit by conducting a second audit. An initial audit of resources and management of postpartum hemorrhage (PPH) was conducted in 2006-2008 in 24 maternity hospitals of the Pays-de-la-Loire. The audit had identified six areas for improvement. A second audit was implemented in 2009-2010 to evaluate the actions of prevention and measure changes in the management of PPH. Two interns have distributed the 24 maternity homes and moved in each hospital to see 10 cases of vaginal delivery (VD) (section "Prevention"), and the last cases of PPH following a VD. The results are in compliance rate compared to the repository of the HAS in 2004. The first audit was conducted on 101 PPH in total. It has allowed us to propose corrective actions to the 24 maternity hospitals: leaf specific monitoring, reporting amounts of blood loss, transfusion on these clinical criteria without waiting for the blood cell counts, indicating more frequent and rapid sulprostone, set for maternity hospitals without surgical skill an agreement with a visceral surgery department, and avoid maternal transfers for PPH. For the second audit, the compliance rate of the preventive aspect was 73% (95: 71-75%) of 239 cases of BA with variations according to maternity from 48 to 93%. Compliance rates according to the criteria were: 99% obstetric consultations, 98% for anesthesia, 92% for hemoglobin, 77% for the group card available in the record, 89% agglutinins, 35% for the notification of the installation of bag, 36% for the notification of the amount of blood lost, 69% for the supervisor within two hours, and 64% for the directed delivery. For component "Support", the overall compliance rate was 81% (95: 79-83%) of 118 PPH AVB, and 85% in the 71 uterine atonies in 21 pregnancies (3 had no HPP

    The objectives of the investigation were to describe changes in mandibular bone structure with aging and to compare the usefulness of cortical and trabecular bone for fracture prediction. From 1968 to 1993, 1,003 women were examined. With the help of panoramic radiographs, cortex thickness was measured and cortex was categorized as: normal, moderately, or severely eroded. The trabeculation was assessed as sparse, mixed, or dense. Visually, the mandibular compact and trabecular bone transformed gradually during the 24 years. The compact bone became more porous, the intertrabecular spaces increased, and the radiographic image of the trabeculae seemed less mineralized. Cortex thickness increased up to the age of 50 and decreased significantly thereafter. At all examinations, the sparse trabeculation group had more fractures (71-78 %) than the non-sparse group (27-31 %), whereas the severely eroded compact group showed more fractures than the less eroded groups only in 1992/1993, 24 years later. Sparse trabecular pattern was associated with future fractures both in perimenopausal and older women (relative risk (RR), 1.47-4.37) and cortical erosion in older women (RR, 1.35-1.55). RR for future fracture associated with a severely eroded cortex increased to 4.98 for cohort 1930 in 1992/1993. RR for future fracture associated with sparse trabeculation increased to 11.43 for cohort 1922 in 1992/1993. Dental radiographs contain enough information to identify women most at risk of future fracture. When observing sparse mandibular trabeculation, dentists can identify 40-69 % of women at risk for future fractures, depending on participant age at examination.

    The aim of this study was to describe the imaging features of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma. The chest radiographs (n = 18) and CT scans (n = 17) of 24 patients (18 men and 6 women) aged 27-78 years (mean = 56 years), with a known diagnosis of pulmonary MALT lymphoma, were retrospectively reviewed by two radiologists and the imaging findings are described. Six of the 24 patients had a history of an autoimmune disorder and 1 patient had acquired immune deficiency syndrome. Multiple pulmonary lesions were identified in 19 of 24 patients (79 %) and solitary lesions in 4 of 24 patients (17 %). Diffuse pulmonary infiltration was present in 1 patient. Lesions included masses or mass-like areas of consolidation (n = 21) and pulmonary nodules (n = 18). Associated findings were air bronchograms, airway dilatation, a positive angiogram sign and a halo of ground-glass shadowing at lesion margins. Peribronchovascular thickening was also observed, as were hilar or mediastinal lymph node enlargement and pleural effusions or thickening. Although rare, the diagnosis of pulmonary MALT lymphoma should be considered in patients with the imaging features described, particularly when in association with an indolent clinical course or a history of autoimmune disease.

Seventeen cats had historical, clinical, and pathological findings of systemic disease. Twelve cats had focal signs of central nervous system dysfunction. Twelve cats had multifocal signs including seizures, nystagmus, head tilt, vestibular or cerebellar ataxia, paresis, and proprioceptive loss with a preponderance of caudal fossa signs. Computed tomography of the brain revealed hydrocephalus in two cats. Examination of cerebrospinal fluid revealed pyogranulomatous pleocytosis in fivecats; the tap was nonproductive in five cats. Findings on histopathological examination of appropriate tissues included nephritis, hepatitis, and pleuritis. Neuropathological findings included ependymitis, choroid plexitis, meningitis, encephalitis, and myelitis. Hydrocephalus was seen in 18 cats on necropsy

    The back-angle yields of the oxygen and carbon particles from the 24 Mg+ 16 O reaction have been measured at E/sub Lab/( 24 Mg) = 79.5 MeV by using reverse kinematics. Comparison with data for the 28 Si+ 12 C reaction forming the same compound nucleus at the same excitation energy and with very similar spin distribution, demonstrates a strong entrance channel effect which is favoring the break-up into the entrance channel with large excitation energy. This result qualitatively supports the picture of the formation of a long-lived orbiting complex whose structure and decay are dependent on the entrance channel. The compound nucleus contribution has been inferred to be less than 15% of the measured oxygen cross-section. 9 references

    When designing pipelines for cold environments, it is important to know how to predict potential problems due to wax deposition on the pipeline's inner surface. The goal of this work was to determine the rate of wax buildup and the maximum, equlibrium wax thickness for a North Sea field loading line. The experimental techniques and results used to evaluate the waxing potential of the crude oil (B) are described. Also, the theoretic model which was used for predicting the maximum wax deposit thickness in the crude oil (B) loading pipeline at controlled temperatures of 40 F (4.4 C) and 100 F (38 C), is illustrated. Included is a recommendation of a procedure for using hot oil at the end of a tanker loading period in order to dewax the crude oil (B) line. This technique would give maximum heating of the pipeline and should be followed by shutting the hot oil into the pipeline at the end of the loading cycle which will provide a hot oil soaking to help soften existing wax. 14 references.

    Full Text Available ObjectiveTo observe the therapeutic effect of terlipressin combined with albumin in management of patients with hepatorenal syndrome. MethodsA retrospective study enrolling 46 patients with hepatorenal syndrome from May 2011 to August 2013 was conducted, in which 22 patients were allocated to control group, and 24 patients to treatment group. In addition to conventional treatment, albumin was used in control group, and the patients in treatment group were treated with terlipressin plus albumin. Clinical symptoms, urine volume, serum creatinine, urea nitrogen, ascites, and prognosis were observed in the study. The Student′s t test was used for comparison between the two groups, and the chi-square test was used for comparison of rates. ResultsThe treatment group showed significant improvements in clinical symptoms, while the control group did not. In treatment group, urine volume (ml/24 h increased from (758.5±284.9 to (2277.1±704.8 (P<0.01; serum creatinine level (μmol/L dropped from (234.2±87.2 to (126.8±62.2 (P<0.01; urea nitrogen level (mmol/L dropped from (18.1±6.4 to (10.3±4.5 (P<0.01; body weight (kg dropped from (68.1±3.9 to (646±3.9 (P<0.01; abdominal circumference (cm dropped from (95.0±5.1 to (90.8±4.9 (P<0.01. However, the control group showed no significant changes in urine volume, serum creatinine, urea nitrogen, body weight, and abdominal circumference after treatment (P>0.05. There were significant differences in these indices between the two groups after treatment (P<0.05. Significant differences in remission rate and survival rate were observed between the control group and treatment group (P<0.05. ConclusionA combination of terlipressin and albumin has favorable therapeutic effect on hepatorenal syndrome and improves the prognosis of patients with hepatorenal syndrome.

  20. Disruption of transitional stages in 24-h blood pressure in renal transplant recipients

    Full Text Available Patients with kidney replacement exhibit disrupted circadian rhythms. Most studies measuring blood pressure use the dipper/non-dipper classification, which does not consider analysis of transitional stages between low and high blood pressure, confidence intervals nor shifts in the time of peak, while assuming subjective onsets of night and day phases. In order to better understand the nature of daily variation of blood pressure in these patients, we analyzed 24h recordings from 41 renal transplant recipients using the non-symmetrical double-logistic fitting assessment which does not assume abruptness nor symmetry in ascending and descending stages of the blood pressure profile, and a cosine best-fitting regression method (Cosinor. Compared with matched controls, double-logistic fitting showed that the times for most of transitional stages (ascending systolic and descending systolic, diastolic and mean arterial pressure had a wider distribution along the 24 h. The proportion of individuals without daily blood pressure rhythm in the transplanted group was larger only for systolic arterial pressure, and the amplitude showed no significant difference. Furthermore, the transplant recipient group had a less pronounced slope in descending systolic and ascending mean blood pressure. Cosinor analysis confirmed the phase related changes, showing a wider distribution of times of peak (acrophases. We conclude that daily disruptions in renal transplant recipients can be explained not only by absence in diurnal variation, but also in changes in waveform-related parameters of the rhythm, and that distortions in the phase of the rhythm are the most consistent finding for the patients.

    Concentrations of 17 neuro-active pharmaceuticals and their major metabolites (bupropion, hydroxy-bupropion, erythro-hydrobupropion, threo-hydrobupropion, carbamazepine, 10,11,-dihydro-10,11,-dihydroxycarbamazepine, 10-hydroxy-carbamazepine, citalopram, N-desmethyl-citalopram, fluoxetine, norfluoxetine, gabapentin, lamotrigine, 2-N-glucuronide-lamotrigine, oxcarbazepine, venlafaxine and O-desmethyl-venlafaxine), were measured in treated wastewater and receiving surface waters from 24 locations across Minnesota, USA. The analysis of upstream and downstream sampling sites indicated that the wastewater treatment plants were the major source of the neuro-active pharmaceuticals and associated metabolites in surface waters of Minnesota. Concentrations of parent compound and the associated metabolite varied substantially between treatment plants (concentrations ± standard deviation of the parent compound relative to its major metabolite) as illustrated by the following examples; bupropion and hydrobupropion 700 ± 1000 ng L−1, 2100 ± 1700 ng L−1, carbamazepine and 10-hydroxy-carbamazepine 480 ± 380 ng L−1, 360 ± 400 ng L−1, venlafaxine and O-desmethyl-venlafaxine 1400 ± 1300 ng L−1, 1800 ± 2300 ng L−1. Metabolites of the neuro-active compounds were commonly found at higher or comparable concentrations to the parent compounds in wastewater effluent and the receiving surface water. Neuro-active pharmaceuticals and associated metabolites were detected only sporadically in samples upstream from the effluent outfall. Metabolite to parent ratios were used to evaluate transformation, and we determined that ratios in wastewater were much lower than those reported in urine, indicating that the metabolites are relatively more labile than the parent compounds in the treatment plants and in receiving waters. The widespread occurrence of neuro-active pharmaceuticals and metabolites in Minnesota effluents and surface waters indicate that this is likely a global environmental issue, and further understanding of the environmental fate and impacts of these compounds is warranted.

    In this study, we performed a comparative analysis of the physiological and biochemical parameters of wheat cultivars with contrasting drought resistance, drought-resistant Omskaya 35 (O-35) and less drought-resistant Salavat Yulaev (SYu), during 7-day germination under drought stress simulated by 5% mannitol. In addition, we evaluated the effectiveness of pre-sowing seed treatment with 0.4 μM 24-epibrassinolide (EBR) used to increase the resistance of plants of both cultivars to drought stress. It was revealed that mannitol has caused significant changes in the hormonal balance of the plants of both cultivars, associated with abscisic acid (ABA) accumulation and decrease in the contents of indoleacetic acid (IAA) and cytokinins (CKs). It should be noted that more dramatic changes in the content of phytohormones were characteristic for seedlings of SYu cultivar, which was reflected in a stronger growth inhibition of these plants. Pretreatment with EBR mitigated the negative effect of drought on the hormonal status and growth of seedlings during their germination. Furthermore, we found that drought caused accumulation of dehydrin (DHN) proteins, especially of low molecular weight DHNs, whose abundance was 2.5 times greater in O-35 cultivar than in SYu plants. EBR-pretreated plants of both cultivars were characterized by the additional accumulation of DHNs, indicating their involvement in the development of the EBR-induced wheat drought resistance. The use of fluridone allowed us to demonstrate ABA-dependent and ABA-independent pathways of regulation of low molecular mass dehydrins accumulation by EBR in wheat plants of both cultivars under drought conditions.

    This article aims to investigate the relationship among renewable energy consumption, carbon dioxide (CO 2 ) emissions, and GDP using panel data for 24 Asian countries between 1990 and 2012. Panel cross-sectional dependence tests and unit root test, which considers cross-sectional dependence across countries, are used to ensure that the empirical results are correct. Using the panel cointegration model, the vector error correction model, and the Granger causality test, this paper finds that a long-run equilibrium exists among renewable energy consumption, carbon emission, and GDP. CO 2 emissions have a positive effect on renewable energy consumption in the Philippines, Pakistan, China, Iraq, Yemen, and Saudi Arabia. A 1% increase in GDP will increase renewable energy by 0.64%. Renewable energy is significantly determined by GDP in India, Sri Lanka, the Philippines, Thailand, Turkey, Malaysia, Jordan, United Arab Emirates, Saudi Arabia, and Mongolia. A unidirectional causality runs from GDP to CO 2 emissions, and two bidirectional causal relationships were found between CO 2 emissions and renewable energy consumption and between renewable energy consumption and GDP. The findings can assist governments in curbing pollution from air pollutants, execute energy conservation policy, and reduce unnecessary wastage of energy.

    In this study we evaluated the pituitary-hypothalamic abnormalities of ''idiopathic growth hormone (GH) deficiency'' as demonstrated by MR imaging. Twenty-four patients were examined with a 1.5-T unit using spin echo T-1 weighted images. The patients were divided into two groups according to MR findings: those with ectopic posterior pituitary glands (12 patients), and those with normal posterior pituitary glands (12 patients). Ten patients in the former group and four in the latter group had small anterior pituitary glands. All patients in the former group but only four in the latter group had severe GH deficiencies. Multiple hormone deficiencies were found in eight patients in the former group, but in only two in the latter group. It is speculated that perinatal abnormalities can cause posterior pituitary ectopia and that there is a close correlation between breech delivery and the male disadvantage of posterior pituitary ectopia. Half of our patients with ''idiopathic GH deficiency'' had ectopic posterior pituitaries. GH deficiency with posterior pituitary ectopia should no longer be considered idiopathic because organic lesions can now be identified during life. (orig./GD)

    In the present work, we development a new protocol for liver decellularization in which the hole decellularization was reached over 24 h. Introduction: the availability of transplantable livers is not sufficient to fulfill the current demand for grafts, with the search for therapeutic alternatives having generated different lines of research, one of which is the use of decellularized three-dimensional biological matrices and subsequent cell seeding to obtain a functional organ. Objective: to produce a decellularization protocol from rabbit liver to generate a three-dimensional matrixin which the time period involved didn't pass 24 h. Methods: The decellularization is obtained through the use of water and SDS (0,1-0,3 %), after freezing at -80 degrees, is the best alternative of different physical and/or chemical mechanisms to break down organ cells and leave only the extracellular matriz. After 24 h of retrograde perfusion, a decellularized translucent matrix was generated. To evaluate if the decellularization protocol was successful, with the extracellular matrix being preserved, we carried out histological (light microscopy) and biochemical (DNA quantification) studies. Results: the decellularization process was verified by macroscopic observation of the organ using microscopic observation corroborated the macroscopic results, with the hematoxylin-eosin and Masson staining showing no cells or nuclear material. In addition, the DNA quantification was less than 10% in the decellularized liver compared to control. Finally,the time taken to develop the decellularization protocol was less than 24 hours.

    Full Text Available The partial one-neutron removal cross section of 24O leading to the first excited state in 23O has been measured to be 65.7 ± 5.3 mb with a proton target in inverse kinematics at the beam energy of 62 MeV/nucleon. The decay energy spectrum of the neutron unbound state of 23O was reconstructed from the measured four momenta of 22O and the emitted neutron. A sharp peak was observed at Edecay = 48 ± 3 keV, confirming the previous measurements. The measured partial longitudinal momentum distribution of 23O* showed the d-wave knockout character, providing a support for the Jπ assignment of 5/2+ for this state. The spectroscopic factor for the neutrons in 0d5/2 orbital was deduced, for the first time, to be C2S(0d5/2 = 3.7 ± 0.3 (preliminary by comparing with the result of Glauber model. The relatively large spectroscopic factor supports the N = 16 shell closure in the neutron drip-line nucleus 24O.

    Full Text Available Reliable yield performance is important in cucumber because seed companies prefer to market cultivars adapted to multiple rather than single regions of the U.S. Also, growers benefit by using a cultivar that performs well in many environments. Future performance of cultivars is also important. The objectives of the study were to (i evaluate the yield of cucumber genotypes over successive years and in different locations, and (ii identify cucumber genotypes with high stability for yield. A diverse set of 22 pickling genotypes was evaluated over 3 years (1986, 1987 and 1988 and in 7 locations across the United States. Yield traits were evaluated using once-over harvest and counting the number of fruit that were marketable, culled or oversize. Total yield, marketable yield (total minus culled fruit, early yield (number of oversize fruit, percent culls and fruit per plant were calculated. Data were analyzed with SASGxE and RGxE programs using SAS and R programming languages, respectively. There were strong effects of environment(E as well as genotype(G xE interaction for all traits. Genotypes ‘Regal F1’, ‘Calypso F1’, ‘Carolina F1’, ‘Gy 3’, ‘Gy 14’ and ‘Fremont F1’ had high marketable yield and medium to high stability for all traits. There was an advantage of hybrids over inbreds for trait performance. Hybrids fell into a single cluster with large prediction intervals. Based on the stability statistics and divisive clusters, it appears possible to breed stable cucumber genotypes with high yield. The genotype with highest performance for marketable yield, greatest stability for yield, lowest 1-R2 ratio value (diverse and representative were ‘Marbel F1’ and Gy 14.

    Testicular cancer survivors have impaired gonadal function and increased risk of metabolic syndrome when compared to healthy controls. However, because of the fetal etiology of testicular cancer, familial unrelated healthy men might not be an optimal control group. The objective of this study was to clarify if testicular cancer survivors have impaired gonadal function and increased risk of metabolic syndrome when compared to their biological brothers. A cross-sectional study of testicular cancer survivors (ClinicalTrials.gov number, NCT02240966) was conducted between 2014 and 2016. Of 158 testicular cancer survivors included, 24 had a biological brother who accepted to participate in the study. Serum levels of reproductive hormones and prevalence of metabolic syndrome according to International Diabetes Federation Criteria and National Cholesterol Education Program (Adult Treatment Panel III) criteria comprised the main outcome measures of the study. Median age was similar in testicular cancer survivors and their biological brothers [44 years (IQR 39-50) vs. 46 (40-53) years respectively (p = 0.1)]. In testicular cancer survivors, follow-up since treatment was 12 years (7-19). Serum levels of luteinizing hormone and follicle-stimulating hormone were elevated (p ≤ 0.001), while total testosterone, free testosterone, inhibin B and anti-Müllerian hormone were lower (p ≤ 0.001) in testicular cancer survivors than in their biological brothers. The prevalence of metabolic syndrome was similar and apart from HDL-cholesterol, which was lower in testicular cancer survivors (p = 0.01); there were no differences in the individual components of the metabolic syndrome between testicular cancer survivors and their brothers. In conclusion, gonadal function was impaired in testicular cancer survivors, while we did not detect any difference in the prevalence of metabolic syndrome between testicular cancer survivors and their biological brothers. © 2017 American Society of Andrology and European Academy of Andrology.

    Surveillance of Neisseria gonorrhoeae antimicrobial susceptibility in Europe is performed through the European Gonococcal Antimicrobial Surveillance Programme (Euro-GASP), which additionally provides data to inform the European gonorrhoea treatment guideline; currently recommending ceftriaxone 500 mg plus azithromycin 2 g as first-line therapy. We present antimicrobial susceptibility data from 24 European countries in 2015, linked to epidemiological data of patients, and compare the results to Euro-GASP data from previous years. Antimicrobial susceptibility testing by MIC gradient strips or agar dilution methodology was performed on 2134 N. gonorrhoeae isolates and interpreted using EUCAST breakpoints. Patient variables associated with resistance were established using logistic regression to estimate odds ratios (ORs). In 2015, 1.7% of isolates were cefixime resistant compared to 2.0% in 2014. Ceftriaxone resistance was detected in only one (0.05%) isolate in 2015, compared with five (0.2%) in 2014. Azithromycin resistance was detected in 7.1% of isolates in 2015 (7.9% in 2014), and five (0.2%) isolates displayed high-level azithromycin resistance (MIC ≥ 256 mg/L) compared with one (0.05%) in 2014. Ciprofloxacin resistance remained high (49.4%, vs. 50.7% in 2014). Cefixime resistance significantly increased among heterosexual males (4.1% vs. 1.7% in 2014), which was mainly attributable to data from two countries with high cefixime resistance (~11%), however rates among men-who-have-sex-with-men (MSM) and females continued to decline to 0.5% and 1%, respectively. Azithromycin resistance in MSM and heterosexual males was higher (both 8.1%) than in females (4.9% vs. 2.2% in 2014). The association between azithromycin resistance and previous gonorrhoea infection, observed in 2014, continued in 2015 (OR 2.1, CI 1.2-3.5, p resistance and low overall resistance to ceftriaxone and cefixime. The low cephalosporin resistance may be attributable to the effectiveness of the currently recommended first-line dual antimicrobial therapy; however the high azithromycin resistance threatens the effectiveness of this therapeutic regimen. Whether the global use of azithromycin in mono- or dual antimicrobial therapy of gonorrhoea is contributing to the global increases in azithromycin resistance remains to be elucidated. The increasing cefixime resistance in heterosexual males also needs close monitoring.

    Mineralisation of atrazine in soil has been shown to depend on previous exposure of the herbicide. In this study, 24 Danish soils were collected and screened for potential to mineralise atrazine. Six soils were chosen, because they had never been exposed to atrazine, whereas 18 soils were chosen because of their history of application of atrazine or the related compound terbuthylazine. None of the 24 soils revealed a mineralisation potential of more than 4% of the added atrazine within a 60 day timeframe. In an atrazine adapted French soil, we found 60% mineralisation of atrazine in 30 days. Cattle manure was applied in order to boost the microbial activity, and a 2-3% increase in the atrazine mineralisation was found in some of the temperate soils, while in the highly adapted French soil it caused a 5% reduction. - The study highlights that pre-exposure of soils to triazine herbicides do not result in rapid mineralization in temperate soils.

    The death rate due to suicide in elderly people is particularly high. As part of suicide selective prevention measures for at-risk populations, the WHO recommends training "gatekeepers". In order to assess the impact of gatekeeper training for members of staff, we carried out a controlled quasi-experimental study over the course of one year, comparing 12 nursing homes where at least 30% of the staff had undergone gatekeeper training with 12 nursing homes without trained staff. We collected data about the residents considered to be suicidal, their management further to being identified, as well as measures taken at nursing home level to prevent suicide. The two nursing home groups did not present significantly different characteristics. In the nursing homes with trained staff, the staff were deemed to be better prepared to approach suicidal individuals. The detection of suicidal residents relied more on the whole staff and less on the psychologist alone when compared to nursing homes without trained staff. A significantly larger number of measures were taken to manage suicidal residents in the trained nursing homes. Suicidal residents were more frequently referred to the psychologist. Trained nursing homes put in place significantly more suicide prevention measures at an institutional level. Having trained gatekeepers has an impact not only for the trained individuals but also for the whole institution where they work, both in terms of managing suicidal residents and routine suicide prevention measures.

    Conflicting evidence has been reported on smoking behavior among adults during times of economic downturn. No study has yet investigated young people's smoking and inequalities in smoking during economic recessions. This study examines the association between country-level youth unemployment due to the economic recession and adolescent smoking and smoking inequalities in Europe. The WHO collaborative "Health Behaviour in School-aged Children" study in 2009/2010 included 15-year-old adolescents from 24 European countries (N = 43 093). Socioeconomic position (SEP) was measured by the Family Affluence Scale. Logistic multilevel models were conducted. The absolute rate of youth unemployment in 2010 (during the recession) and the relative change rate in youth unemployment (2005/2006-2009/2010) were regressed on smoking and SEP inequalities in smoking in 2010, respectively. Youth unemployment rates were not significantly associated with overall smoking in adolescents. A higher absolute youth unemployment rate in 2010 related to lower likelihoods of smoking among middle (OR: 0.99; 95% CI: 0.98-0.99) and low affluent adolescents (OR: 0.99; 95% CI: 0.98-0.99) compared to high affluent adolescents. In contrast, an increase in youth unemployment (2005/2006-2009/2010) was not associated with overall likelihoods of smoking and inequalities in smoking. Our findings indicate that an increase in youth unemployment was not related to smoking and smoking inequalities. However, higher absolute levels of youth unemployment are related to lower likelihoods of smoking in lower SEP adolescents. Thus, smoking among vulnerable groups is more linked to the overall insecure circumstances and the affordability of cigarettes rather than to the economic recession itself. Economic recessions have often led to increases in adult and youth unemployment rates. Conflicting evidence has been reported on smoking behavior among adults during times of economic downturn. This study examines for the first time the impact of the economic recession on young people's smoking and socioeconomic inequalities in smoking. Findings highlight that rather than an increase in youth unemployment, the overall country-level youth unemployment rate is related to young people's tobacco use and particularly to lower odds in smoking among less affluent adolescents across Europe, a finding which is likely to be linked to the affordability of tobacco use. © The Author 2016.

    We determined the demographic and HIV test characteristics of tests conducted in CDC-funded sexually transmitted disease (STD) clinics with provision of test results and posttest counseling. We used CDC's HIV Counseling and Testing System data from 2007 for the 24 U.S. health departments that reported test-level data from STD clinics. We calculated and analyzed newly identified HIV positivity and the percentage of tests with provision of test results and posttest counseling (provision of posttest counseling), by demographic and HIV-related characteristics. Of 372,757 tests conducted among people without a previous HIV diagnosis by self-report, provision of posttest counseling was documented for 191,582 (51.4%) HIV tests overall and 1,922 (71.2%) newly identified HIV-positive test results. At these STD clinics, provision of posttest counseling varied by HIV serostatus, age, race/ethnicity, test type, and risk category; however, documentation of posttest counseling was missing for more than 20% of tests. The newly identified HIV positivity among all testers was 0.7%. One of the main goals of HIV counseling and testing is to inform people of their HIV status, because knowledge of one's HIV-positive serostatus can result in a reduction in risk behaviors and allow the person to access HIV medical care and treatment. STD clinics offering HIV testing may need to further their emphasis on increasing the proportion of clients who are provided posttest counseling and on improving documentation of this information.

    The aim of the study was to establish reference intervals for 24-h urinary stone risk factors in the healthy Chinese Han population. From May 2013 to July 2014, we collected and analyzed 24-h urine samples from healthy adult Han population during a cross-sectional study across China. The protocol for analysis of 24-h urine included volume, pH, oxalate, citrate, sodium, potassium, chloride, calcium, phosphorous, creatinine, urate, magnesium, the ion activity products of calcium oxalate (AP(CaOx) indexs) and calcium phosphate (AP(CaP) indexs). We calculated the reference intervals according to the Clinical and Laboratory Standards Institute (CLSI) 2008 guidelines and compared them with those recorded in other studies. A total of 132 male and 123 female healthy subjects with a mean (SD, range) age of 52.4 (15.2, 19-89) years were eligible in the final analysis. Men had higher 24-h excretion of creatinine, calcium, urate and phosphorus and lower levels of citrate, magnesium, chloride, sodium and potassium than women. AP(CaOx) indexs and AP(CaP) indexs were significantly higher among men than women. When urinary findings were compared with the reference intervals, most of our data showed a high abnormality rate, especially for creatinine, calcium, citrate, magnesium, chloride, sodium and potassium. The present study revealed the normal metabolic status for stone risk factors of the Chinese Han population. It is therefore necessary for each country or region to define their own reference intervals for comparison of stone risk factors between patients and healthy subjects.

    Institutional mentoring may be a useful capacity-building model to support local health departments facing public health challenges. The New York City Department of Health and Mental Hygiene conducted a qualitative evaluation of an institutional mentoring program designed to increase capacity of health departments seeking to address chronic disease prevention. The mentoring program included 2 program models, a one-to-one model and a collaborative model, developed and implemented for 24 Communities Putting Prevention to Work grantee communities nationwide. We conducted semi-structured telephone interviews to assess grantees' perspectives on the effectiveness of the mentoring program in supporting their work. Two interviews were conducted with key informants from each participating community. Three evaluators coded and analyzed data using ATLAS.ti software and using grounded theory to identify emerging themes. We completed 90 interviews with 44 mentees. We identified 7 key program strengths: learning from the New York City health department's experience, adapting resources to local needs, incorporating new approaches and sharing strategies, developing the mentor-mentee relationship, creating momentum for action, establishing regular communication, and encouraging peer interaction. Participants overwhelmingly indicated that the mentoring program's key strengths improved their capacity to address chronic disease prevention in their communities. We recommend dissemination of the results achieved, emphasizing the need to adapt the institutional mentoring model to local needs to achieve successful outcomes. We also recommend future research to consider whether a hybrid programmatic model that includes regular one-on-one communication and in-person conferences could be used as a standard framework for institutional mentoring.

  7. No consistent effects of prenatal or neonatal exposure to Spanish flu on late-life mortality in 24 developed countries

    Full Text Available We test the effects of early life exposure to disease on later health by looking for differences in late-life mortality in cohorts born around the 1918-1919 flu pandemic using data from the Human Mortality Database for 24 countries. After controlling for age, period, and sex effects, residual mortality rates did not differ systematically for flu cohorts relative to surrounding cohorts. We calculate at most a 20-day reduction in life expectancy for flu cohorts; likely values are much smaller. Estimates of influenza incidence during the pandemic suggest that exposure was high enough for this to be a robust negative result.

    Bochdalek hernia (BH) is the most common type of congenital diaphragm hernia and is rarely seen in adults. In adult patients, BH often remains asymptomatic or presents with nondiagnostic symptoms and may lead to complications, though rarely. The necrosis and perforations occurring in the hernia may lead to mortality. In this report, we present a 34-year-old pregnant woman at 24 gestational weeks who presented with Bochdalek hernia causing gastric volvulus associated with perforation and intra-abdominal hemorrhage associated with splenic rupture.

    Developmental exposure of mice to the environmental contaminant and AhR agonist, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), causes persistent postnatal suppression of T cell-mediated immune responses. The extent to which prenatal TCDD may induce or exacerbate postnatal autoimmune disease remains unknown. In the present study, time-pregnant high affinity AhR C57BL/6 mice received a single oral administration of 0, 2.5, or 5 μg/kg TCDD on gestation day (gd) 12. Offspring of these mice (n = 5/gender/treatment) were evaluated at 24 weeks-of-age and showed considerable immune dysregulation that was often gender-specific. Decreased thymic weight and percentages of CD4 + CD8 + thymocytes, and increased CD4 + CD8 - thymocytes, were present in the female but not male offspring. Males but not females showed decreased CD4 - CD8 + T cells, and increased Vβ3 + and Vβ17a + T cells, in the spleen. Males but not females also showed increased percentages of bone marrow CD24 - B220 + B cell progenitors. Antibody titers to dsDNA, ssDNA and cardiolipin displayed increasing trends in both male and female mice, reaching significance for anti-dsDNA in both genders and for ssDNA in males at 5 μg/kg TCDD. Immunofluorescent staining of IgG and C3 deposition in kidney glomeruli increased in both genders of prenatal TCDD-exposed mice, suggestive of early stages of autoimmune glomerulonephritis. Collectively, these results show that exposure to TCDD during immune system development causes persistent humoral immune dysregulation as well as altered cell-mediated responses, and induces an adult profile of changes suggestive of increased risk for autoimmune disease

    Nuclear reaction mechanisms for system characterized by very different asymmetries (U+C, Si, Ni, Au) have been investigated at 24.3 MeV/nucleon, using as observables both the fission products and the neutron multiplicity. It is clearly observed that the fusion process-whatever its completeness- can only occur with rather light target nuclei, indicating the persistence of potential energy effects much above the interaction barrier.

    Age is the single greatest risk factor for most causes of morbidity and mortality in humans and their companion animals. As opposed to other model organisms used to study aging, dogs share the human environment, are subject to similar risk factors, receive comparable medical care, and develop many of the same age-related diseases humans do. In this study, 24 middle-aged healthy dogs received either placebo or a non-immunosuppressive dose of rapamycin for 10 weeks. All dogs received clinical and hematological exams before, during, and after the trial and echocardiography before and after the trial. Our results showed no clinical side effects in the rapamycin-treated group compared to dogs receiving the placebo. Echocardiography suggested improvement in both diastolic and systolic age-related measures of heart function (E/A ratio, fractional shortening, and ejection fraction) in the rapamycin-treated dogs. Hematological values remained within the normal range for all parameters studied; however, the mean corpuscular volume (MCV) was decreased in rapamycin-treated dogs. Based on these results, we will test rapamycin on a larger dog cohort for a longer period of time in order to validate its effects on cardiac function and to determine whether it can significantly improve healthspan and reduce mortality in companion dogs.

    The pseudorapidity distribution of shower particles produced in the 24 Mg-emulsion collisions at 4.5 A GeV/c is reported in this paper. The dependences of the distribution width and the peak position on the target size are observed. The pseudorapidity distribution of shower particles for the events with low target multiplicity (light target) is narrower than that with high target multiplicity (heavy target). The maximum probability pseudorapidity for light target is greater than that for heavy target. The experimental data is analyzed by using the cylinder model suggested by Liu et al. The Monte Carlo results based on Liu's cylinder model are approximately in agreement with the experimental tendency and fluctuation. (author)

    Histamine intolerance is thought to trigger manifold clinical symptoms after ingesting histamine-rich food due to reduced activity of diamine oxidase (DAO). No study has hitherto systematically assessed daily fluctuations of histamine levels and DAO activities in symptomatic patients. The aim of the study was to investigate the presence of histamine intolerance, to therefore establish day profiles of histamine levels and DAO activities, and to compare the results between patients with suspected histamine intolerance, food allergy and healthy controls. We determined day profiles of histamine plasma levels and DAO serum activities in 33 patients with suspected histamine intolerance, in 21 patients with proven food allergy and in 10 healthy control patients. Clinical symptoms, food intolerances and further clinical and laboratory chemical parameters were evaluated. Twenty-four percent (8 of 33) suspected histamine-intolerant patients showed elevated histamine levels during the day. That might be caused by constantly and significantly reduced DAO activities in these patients compared to food-allergic and control patients. The remaining 25 patients presented normal histamine levels and DAO activities, but an increased prevalence of multiple food intolerances compared to the other subgroup of suspected histamine-intolerants. There was no correlation between subjective complaints and serological histamine parameters in patients with suspected histamine intolerance. We determined by daily profiling that decreased DAO activities correlated with elevated histamine levels in a subgroup of suspected histamine-intolerants. This finding discriminates these patients from food intolerant individuals with similar clinical symptoms and strongly suggests the presence of histamine intolerance. © 2017 EAACI and John Wiley and Sons A/S.

    The risks and benefits of fish from markets in Chinese cities have not previously been fully evaluated. In the present study, 24 common fish species with more than 400 individual samples were collected from markets from five big Chinese cities in 2007. The main nutrients and contaminants were measured and the risk-benefit was evaluated based on recommended nutrient intakes and risk level criteria set by relevant authorities. The comprehensive effects of nutrients and contaminants in marine oily fish were also evaluated using the data of two related human dietary intervention trials performed in dyslipidemic Chinese men and women in 2008 and 2010, respectively. The results showed that concentrations of contaminants analyzed including DDT, PCB{sub 7}, arsenic and cadmium were much lower than their corresponding maximum limits with the exception of the mercury concentration in common carp. Concentrations of POPs and n-3 LCPUFA, mainly EPA and DHA, were positively associated with the lipid content of the fish. With a daily intake of 80-100 g marine oily fish, the persistent organic pollutants in fish would not counteract the beneficial effects of n-3 LCPUFA in reducing cardiovascular disease (CVD) risk markers. Marine oily fish provided more effective protection against CVD than lean fish, particularly for the dyslipidemic populations. The risk-benefit assessment based on the present daily aquatic product intake in Chinese urban residents (44.9 and 62.3 g for the average values for all cities and big cities, respectively) indicated that fish, particularly marine oily fish, can be regularly consumed to achieve optimal nutritional benefits from n-3 LCPUFA, without causing significant contaminant-related health risks. However, the potential health threat from contaminants in fish should still be emphasized for the populations consuming large quantities of fish, particularly wild fish. - Highlights: Black-Right-Pointing-Pointer We collected 24 fish species with more than 400 individual samples from five big Chinese cities. Black-Right-Pointing-Pointer The health risk-benefit was evaluated based on the nutrients and contaminants content in fish. Black-Right-Pointing-Pointer Two human trials were performed to evaluate the effects of contaminated fish on CVD prevalence. Black-Right-Pointing-Pointer Contaminants in these fish couldn't alleviate the benefits of fish n-3 LCPUFA in CVD prevention. Black-Right-Pointing-Pointer These fish in China can be regularly consumed without causing contaminant-related health risks.

    Objectives The aim of this study was to determine in-house reference intervals (RIs) for venous blood analysis with the RAPIDPoint 500 blood gas analyser using blood gas syringes (BGSs) and to determine whether immediate analysis of venous blood collected into lithium heparin (LH) tubes can replace anaerobic blood sampling into BGSs. Methods Venous blood was collected from 24 healthy cats and directly transferred into a BGS and an LH tube. The BGS was immediately analysed on the RAPIDPoint 500 followed by the LH tube. The BGSs and LH tubes were compared using paired t-test or Wilcoxon matched-pairs signed-rank test, Bland-Altman and Passing-Bablok analysis. To assess clinical relevance, bias or percentage bias between BGSs and LH tubes was compared with the allowable total error (TEa) recommended for the respective parameter. Results Based on the values obtained from the BGSs, RIs were calculated for the evaluated parameters, including blood gases, electrolytes, glucose and lactate. Values derived from LH tubes showed no significant difference for standard bicarbonate, whole blood base excess, haematocrit, total haemoglobin, sodium, potassium, chloride, glucose and lactate, while pH, partial pressure of carbon dioxide and oxygen, actual bicarbonate, extracellular base excess, ionised calcium and anion gap were significantly different to the samples collected in BGSs ( P glucose and lactate can be made based on blood collected in LH tubes and analysed within 5 mins. For pH, partial pressure of carbon dioxide and oxygen, extracellular base excess, anion gap and ionised calcium the clinically relevant alterations have to be considered if analysed in LH tubes.

    One limitation of several recent 24 week Alzheimer's disease (AD) clinical trials was the lack of cognitive decline detected by the AD Assessment Scale-cognitive subscale (ADAS-cog) in the placebo groups, possibly obscuring true medication effects. Data from 733 individuals in the placebo arms of six AD clinical trials performed 1996-1997 were pooled to examine the relationship of clinical, demographic, and genetic characteristics with the 24 week change in ADAS-cog. Baseline cognitive and functional status and the screening-to-baseline change in ADAS-cog were the strongest independent predictors of the 24 week change in ADAS-cog. The ADAS-cog did not detect progression in patients with mild dementia (screening Mini-Mental State Exam, MMSE, >or=20). The change in ADAS-cog from screening to baseline was inversely correlated with the 24 week change score; it was more difficult to detect cognitive decline at 24 weeks if individuals markedly worsened from screening to baseline. The effects of baseline MMSE and screening-to-baseline change in ADAS-cog generalized to the placebo group (N=106) of another AD study performed in 2004-2005. Overcoming lack of placebo decline in AD clinical trials will require scales more sensitive to cognitive decline in mild AD and strategies to reduce within-person variability in outcome measures.

    Fission is a powerful tool for studying the primary reaction mechanisms in nucleus-nucleus collisions involving at least one fissionable nucleus. This is well shown when an additional information on the violence of the collision is provided by a totally independent observable such as the neutron multiplicity. The mass asymmetry in the entrance channel and the impact parameter are shown to have a decisive influence on the fate of the collision leading to either fusion or a two-body deeply inelastic reaction, analogous to what is known at lower bombarding energies. The experimental approach allows also to single out electromagnetic fission of U after interaction with Au and to provide some characteristics of such a process. (author)

    The present survey aims at determining the prevalence of extreme obesity (defined as a body mass index (BMI) ≥ 99.5th percentile) for the first time in Austria and at investigating the relationship between weight status and mother tongue in a representative Viennese sample of 24,989 children and adolescents (2-16 years) with a percentage of approximately 46 % of migration background.Directly measured anthropometric data on body weight and height were collected and BMI was calculated. Prevalence of overweight, obesity and extreme obesity was determined for every subgroup according to mother tongue using the German national reference criteria by Kromeyer-Hauschild et al.In this sample, 2.1 % of all children and adolescents had to be classified as being extremely obese. More boys (2.3 %) than girls (1.9 %) suffered from extreme obesity (p = 0.048). Total 1.7 % of children and adolescents with German as their native language, 2.5 % of Turkish native speakers and 2.9 % of children and adolescents with another mother tongue were extremely obese (p ≤ 0.001). The highest prevalence of overweight or obesity was found in Turkish-native-speaking children and adolescents (p ≤ 0.001), whereas the lowest one was found in German-native-speaking children and adolescents (p ≤ 0.001).This large study clearly shows that extreme obesity is a common disease and largely neglected. Apparently, another native language than German, as an indicator for a migration background, may be associated with a substantially higher probability for the development of extreme obesity in Vienna, Austria. Thus, effective preventive measures to overcome obesity are urgently needed.

    Serum, plasma and dietary magnesium (Mg) have been reported to be inversely associated with cardiovascular disease risk factors. We examined the associations between the 24-h urinary Mg/creatinine (Cre) ratio and cardiovascular disease risk factors, such as body mass index (BMI), blood pressure (BP), serum total cholesterol (TC) and prevalence of obesity, hypertension and hypercholesterolemia. A cross-sectional analysis was conducted among 4211 participants (49.7% women) aged 48-56 years in 50 population samples from 22 countries in the World Health Organization-coordinated Cardiovascular Diseases and Alimentary Comparison (CARDIAC) Study (1985-1994). In linear regression analyses, Mg/Cre ratio was inversely associated with BMI, systolic BP (SBP), diastolic BP (DBP) and TC (P for linear trend <0.001 for each). These associations were not markedly altered by adjustment for traditional risk factors, urinary markers or cohort effects. Multivariate-adjusted mean values for the subjects in the highest Mg/Cre ratio quintile were 6.3, 3.4, 5.3 and 4.6% lower than those for the subjects in the lowest quintile for BMI, SBP, DBP and TC (P < 0.001, respectively). The prevalence of obesity, hypertension and hypercholesterolemia was 2.10 (95% confidence interval: 1.50, 2.95), 1.55 (1.25, 1.92) and 2.06 (1.63, 2.62) times higher (P < 0.001, respectively) among the subjects in the lowest Mg/Cre ratio quintile than in the subjects in the highest quintile. These associations were not appreciably altered by adjustment for potential confounding variables. In conclusion, higher 24-h urinary Mg/Cre ratio was associated with lower cardiovascular disease risk factors, including BMI, BP, TC, obesity, hypertension and hypercholesterolemia.

    The risks and benefits of fish from markets in Chinese cities have not previously been fully evaluated. In the present study, 24 common fish species with more than 400 individual samples were collected from markets from five big Chinese cities in 2007. The main nutrients and contaminants were measured and the risk–benefit was evaluated based on recommended nutrient intakes and risk level criteria set by relevant authorities. The comprehensive effects of nutrients and contaminants in marine oily fish were also evaluated using the data of two related human dietary intervention trials performed in dyslipidemic Chinese men and women in 2008 and 2010, respectively. The results showed that concentrations of contaminants analyzed including DDT, PCB 7 , arsenic and cadmium were much lower than their corresponding maximum limits with the exception of the mercury concentration in common carp. Concentrations of POPs and n-3 LCPUFA, mainly EPA and DHA, were positively associated with the lipid content of the fish. With a daily intake of 80–100 g marine oily fish, the persistent organic pollutants in fish would not counteract the beneficial effects of n-3 LCPUFA in reducing cardiovascular disease (CVD) risk markers. Marine oily fish provided more effective protection against CVD than lean fish, particularly for the dyslipidemic populations. The risk–benefit assessment based on the present daily aquatic product intake in Chinese urban residents (44.9 and 62.3 g for the average values for all cities and big cities, respectively) indicated that fish, particularly marine oily fish, can be regularly consumed to achieve optimal nutritional benefits from n-3 LCPUFA, without causing significant contaminant-related health risks. However, the potential health threat from contaminants in fish should still be emphasized for the populations consuming large quantities of fish, particularly wild fish. - Highlights: ► We collected 24 fish species with more than 400 individual samples from five big Chinese cities. ► The health risk–benefit was evaluated based on the nutrients and contaminants content in fish. ► Two human trials were performed to evaluate the effects of contaminated fish on CVD prevalence. ► Contaminants in these fish couldn't alleviate the benefits of fish n-3 LCPUFA in CVD prevention. ► These fish in China can be regularly consumed without causing contaminant-related health risks.

    We recently reported on the deficiency of carbohydrate sulfotransferase 3 (CHST3; chondroitin-6-sulfotransferase) in six subjects diagnosed with recessive Larsen syndrome or humero-spinal dysostosis [Hermanns et al. (2008); Am J Hum Genet 82:1368-1374]. Since then, we have identified 17 additional families with CHST3 mutations and we report here on a series of 24 patients in 23 families. The diagnostic hypothesis prior to molecular analysis had been: Larsen syndrome (15 families), humero-spinal dysostosis (four cases), chondrodysplasia with multiple dislocations (CDMD "Megarbane type"; two cases), Desbuquois syndrome (one case), and spondylo-epiphyseal dysplasia (one case). In spite of the different diagnostic labels, the clinical features in these patients were similar and included dislocation of the knees and/or hips at birth, clubfoot, elbow joint dysplasia with subluxation and limited extension, short stature, and progressive kyphosis developing in late childhood. The most useful radiographic clues were the changes of the lumbar vertebrae. Twenty-four different CHST3 mutations were identified; 16 patients had homozygous mutations. We conclude that CHST3 deficiency presents at birth with congenital dislocations of knees, hips, and elbows, and is often diagnosed initially as Larsen syndrome, humero-spinal dysostosis, or chondrodysplasia with dislocations. The incidence of CHST3 deficiency seems to be higher than assumed so far. The clinical and radiographic pattern (joint dislocations, vertebral changes, normal carpal age, lack of facial flattening, and recessive inheritance) is characteristic and distinguishes CHST3 deficiency from other disorders with congenital dislocations such as filamin B-associated dominant Larsen syndrome and Desbuquois syndrome.

    Full Text Available Lead and lead-containing compounds are considered as toxic substances due to their detrimental effect on the environment. Sn-based soldering systems, like Sn-Cu and Sn-Zn are considered as the most promising candidates to replace the eutectic Sn-Pb solder compared to other solders because of their low melting temperature and favorable properties. Eutectic Sn-0.7 wt.% Cu and near eutectic composition Sn-8 wt.% Zn solders have been considered here for study. For the Sn-Cu system, besides the eutectic Sn-0.7 wt.% Cu composition, Sn-1Cu and Sn-2Cu were studied. Three compositions containing Ag: Sn-2Ag-0.7Cu, Sn-2.5Ag-0.7Cu and Sn-4.5Ag-0.7Cu were also developed. Ag was added to the eutectic Sn-0.7 wt.% Cu composition in order to reduce the melting temperature of the eutectic alloy and to enhance the mechanical properties. For the Sn-Zn system, besides the Sn-8 wt.% Zn near eutectic composition, Sn-8Zn-0.05Ag, Sn-8Zn-0.1Ag and Sn-8Zn-0.2Ag solder alloys were developed. The structure and morphology of the solder alloys were analyzed using a scanning electron microscope (SEM, filed emission scanning electron microscope (FESEM, electron diffraction X-ray spectroscopy (EDX and X-ray diffraction (XRD. Thermal analysis of the alloys was also done using a differential scanning calorimeter (DSC. Trace additions of Ag have been found to significantly reduce the melting temperature of the Sn-0.7 wt.% Cu and Sn-8 wt.% Zn alloys.

    Report contains detailed results of a number of fatigue tests on spot-welded joints in aluminum alloys. The tests described include: (1) fatigue tests on spot-welded lap joints in sheets of unequal thickness of alclad 24s-t. These tests indicate that the fatigue strength of a spot-welded joint in sheets of two different gages is slightly higher than that of a similar joint in two sheets of the thinner gage but definitely lower than that of a similar joint in two sheets of the thicker gage. (2) Fatigue tests on spot-welded alclad 75s-t spot-welded lap-joint specimens of alclad 75s-t were not any stronger in fatigue than similar specimens of alclad 24s-t. (3) Fatigue tests on lap-joint specimens spot -welded after various surface preparations--these included ac welding wire-brushed surfaces, dc welding wire-brushed surfaces, and dc welding chemically cleaned surfaces. While the ac welds were strongest statically, the dc welds on wire-brushed surfaces were strongest in fatigue. Specimens prepared in this way were very nearly as strong as the best riveted specimens tested for comparison. (4) Fatigue tests on specimens spot-welded with varying voltage so as to include a wide range of static spot-weld strengths. The fatigue strengths were in the same order as the static strengths but showed less range. (author)

    The aim of this study is the evaluation of radiation effects in detectors based on p-type magnetic czochralski (MCZ) Si that was converted to n-type by thermal donor (TD) introduction. As-processed p + -p-n + detectors were annealed at 430 deg. C resulting in p + -n(TD)-n + structures. The space charge sign and the electric field distribution E(x) in MCz Si p + -n(TD)-n + detectors irradiated by 24 GeV/c protons were analyzed using the data on the current pulse response and the Double Peak (DP) electric field distribution model for heavily irradiated detectors. The approach considers an irradiated detector as a structure with three regions in which the electric field depends on the coordinate, and the induced current pulse response arises from the drift process of free carriers in the detector with variable electric field. Reconstruction of the E(x) profile from the pulse response shapes is performed employing a new method for DP electric field reconstruction. This method includes: (a) a direct extraction of charge loss due to trapping and (b) the fitting of a simulated pulse response to the 'corrected' pulse by adjusting the electric field profiles in the three regions. Reconstruction of E(x) distribution showed that in the diodes irradiated by a proton fluence of (2-4)x10 14 p/cm 2 space charge sign inversion has occurred. This is the evidence that the influence of 24 GeV/c proton radiation on MCz Si p + -n(TD)-n + detectors is similar to that on p + -n-n + detectors based on FZ or diffusion oxygenated n-type Si.

  18. Effects of Diclofenac, L-NAME, L-Arginine, and Pentadecapeptide BPC 157 on Gastrointestinal, Liver, and Brain Lesions, Failed Anastomosis, and Intestinal Adaptation Deterioration in 24 Hour-Short-Bowel Rats.

    Stable gastric pentadecapeptide BPC 157 was previously used to ameliorate wound healing following major surgery and counteract diclofenac toxicity. To resolve the increasing early risks following major massive small bowel resectioning surgery, diclofenac combined with nitric oxide (NO) system blockade was used, suggesting therapy with BPC 157 and the nitric oxide synthase (NOS substrate) L-arginine, is efficacious. Immediately after anastomosis creation, short-bowel rats were untreated or administered intraperitoneal diclofenac (12 mg/kg), BPC 157 (10 μg/kg or 10 ng/kg), L-NG-nitroarginine methyl ester (L-NAME, 5 mg/kg), L-arginine (100 mg/kg) alone or combined, and assessed 24 h later. Short-bowel rats exhibited poor anastomosis healing, failed intestine adaptation, and gastrointestinal, liver, and brain lesions, which worsened with diclofenac. This was gradually ameliorated by immediate therapy with BPC 157 and L-arginine. Contrastingly, NOS-blocker L-NAME induced further aggravation and lesions gradually worsened. Specifically, rats with surgery alone exhibited mild stomach/duodenum lesions, considerable liver lesions, and severe cerebral/hippocampal lesions while those also administered diclofenac showed widespread severe lesions in the gastrointestinal tract, liver, cerebellar nuclear/Purkinje cells, and cerebrum/hippocampus. Rats subjected to surgery, diclofenac, and L-NAME exhibited the mentioned lesions, worsening anastomosis, and macro/microscopical necrosis. Thus, rats subjected to surgery alone showed evidence of deterioration. Furtheremore, rats subjected to surgery and administered diclofenac showed worse symptoms, than the rats subjected to surgery alone did. Rats subjected to surgery combined with diclofenac and L-NAME showed the worst deterioration. Rats subjected to surgery exhibited habitual adaptation of the remaining small intestine, which was markedly reversed in rats subjected to surgery and diclofenac, and those with surgery, diclofenac, and L-NAME. BPC 157 completely ameliorated symptoms in massive intestinal resection-, massive intestinal resection plus diclofenac-, and massive intestinal resection plus diclofenac plus L-NAME-treated short bowel rats that presented with cyclooxygenase (COX)-NO-system inhibition. L-arginine ameliorated only L-NAME-induced aggravation of symptoms in rats subjected to massive intestinal resection and administered diclofenac plus L-NAME.

    Full Text Available Abstract Background So far very limited knowledge exists on L-arginine catabolism in cyanobacteria, although six major L-arginine-degrading pathways have been described for prokaryotes. Thus, we have performed a bioinformatic analysis of possible L-arginine-degrading pathways in cyanobacteria. Further, we chose Synechocystis sp. PCC 6803 for a more detailed bioinformatic analysis and for validation of the bioinformatic predictions on L-arginine catabolism with a transcript analysis. Results We have evaluated 24 cyanobacterial genomes of freshwater or marine strains for the presence of putative L-arginine-degrading enzymes. We identified an L-arginine decarboxylase pathway in all 24 strains. In addition, cyanobacteria have one or two further pathways representing either an arginase pathway or L-arginine deiminase pathway or an L-arginine oxidase/dehydrogenase pathway. An L-arginine amidinotransferase pathway as a major L-arginine-degrading pathway is not likely but can not be entirely excluded. A rather unusual finding was that the cyanobacterial L-arginine deiminases are substantially larger than the enzymes in non-photosynthetic bacteria and that they are membrane-bound. A more detailed bioinformatic analysis of Synechocystis sp. PCC 6803 revealed that three different L-arginine-degrading pathways may in principle be functional in this cyanobacterium. These are (i an L-arginine decarboxylase pathway, (ii an L-arginine deiminase pathway, and (iii an L-arginine oxidase/dehydrogenase pathway. A transcript analysis of cells grown either with nitrate or L-arginine as sole N-source and with an illumination of 50 μmol photons m-2 s-1 showed that the transcripts for the first enzyme(s of all three pathways were present, but that the transcript levels for the L-arginine deiminase and the L-arginine oxidase/dehydrogenase were substantially higher than that of the three isoenzymes of L-arginine decarboxylase. Conclusion The evaluation of 24 cyanobacterial genomes revealed that five different L-arginine-degrading pathways are present in the investigated cyanobacterial species. In Synechocystis sp. PCC 6803 an L-arginine deiminase pathway and an L-arginine oxidase/dehydrogenase pathway represent the major pathways, while the L-arginine decarboxylase pathway most likely only functions in polyamine biosynthesis. The transcripts encoding the enzymes of the two major pathways were constitutively expressed with the exception of the transcript for the carbamate kinase, which was substantially up-regulated in cells grown with L-arginine.

    Full Text Available Approximately 85% of the water consumed in Chile is destined to agricultural irrigation and is managed by the users themselves. This study analyzed the price that irrigation water users pay to their Water User Associations (WUAs to which they belong and the relationship of this price to the professional level and performance of the WUAs. The study included 24 WUAs: 10 River Administration Boards (JV and 14 Irrigation Canal Associations (AC. The annual operational budget of each WUA, the price paid by users and the management capacities of the board of directors of each WUA were compared. The study also determined the relative value of user payments to WUAs as a proportion of total production costs of the main crops in each zone. The variability of user fees per irrigated hectare decreases when the irrigation area of the WUA is more than 10 000 ha, though this was not observed in JVs. The presence of technical-professional staff directly affects the development and growth of the WUAs. As well, the WUAs with a greater level of capacity development (NDC have more board members with a higher education level and have lower rates of unpaid user fees. The price that users pay to the WUA by irrigated hectare represents less than 4.0% of the average total production cost of the main crops in the study area. Finally, no correlation was found between the prices that users pay and the average profitability of the main crops, or between price and the geographical location of the WUAs.Aproximadamente, el 85% del agua consumida en Chile es destinada al riego agrícola, siendo administrada por los propios usuarios. En este estudio, se analizó el costo que cancelan los usuarios del agua de riego a sus Organizaciones de Usuarios de Agua (WUAs y el nivel de profesionalización y desempeño de éstas. Se estudiaron 24 WUAs: 10 Juntas de Vigilancia (JV y 14 Asociaciones de Canalistas (AC. Se comparó el presupuesto anual de operaciones de cada WUA, el valor que cancelan los usuarios y las capacidades de gestión de la directiva con el desempeño de la respectiva WUA. Además, se analizó la significancia del pago de los usuarios en los costos de producción de los principales cultivos en cada zona. En las AC, la variabilidad de precios por hectárea regada que cancelan los usuarios, disminuye cuando el territorio de la WUA es mayor a 10 000 ha, situación no detectada en las JV. El personal técnico-profesional de apoyo incide directamente sobre el desarrollo y crecimiento de las WUAs. Asimismo, las WUAs con nivel de desarrollo de capacidades (NDC más elevado poseen directivas con mayor escolaridad promedio y los usuarios presentan menor morosidad en el pago. El precio que cancelan los usuarios a las WUAs por hectárea regada representa menos del 4,0% de los costos promedio totales de producción de los principales cultivos de cada zona. Finalmente, no se evidenció correlación entre el precio que cancelan los usuarios y la rentabilidad promedio de los cultivos, ni por ubicación geográfica de las WUAs.

    Full Text Available Abstract Background Prader-Willi syndrome (PWS is a complex neurodevelopmental genetic disorder with hypothalamic dysfunction, early morbid obesity with hyperphagia, and specific psychiatric phenotypes including cognitive and behavioural problems, particularly disruptive behaviours and frequent temper outbursts that preclude socialization. A deficit in oxytocin (OT-producing neurons of the hypothalamic paraventricular nucleus has been reported in these patients. Methods In a double-blind, randomised, placebo-controlled study, 24 adult patients with PWS received a single intranasal administration of 24 IU of OT or placebo and were tested 45 min later on social skills. Behaviours were carefully monitored and scored using an in-house grid as follows: over the two days before drug administration, on the half-day following administration, and over the subsequent two days. All patients were in a dedicated PWS centre with more than ten years of experience. Patients are regularly admitted to this controlled environment. Results Patients with PWS who received a single intranasal administration of OT displayed significantly increased trust in others (P = 0.02 and decreased sadness tendencies (P = 0.02 with less disruptive behaviour (P = 0.03 in the two days following administration than did patients who received placebo. In the half-day following administration, we observed a trend towards less conflict with others (p = 0.07 in the OT group compared with the placebo group. Scores in tests assessing social skills were not significantly different between the two groups. Conclusions This study needs to be reproduced and adapted. It nevertheless opens new perspectives for patients with PWS and perhaps other syndromes with behavioural disturbances and obesity. Trial registration number ClinicalTrials.gov: NCT01038570

    In this article, we report on the preparation of the pitaya-like Sn@C nanocomposite with an aerosol spray pyrolysis and its application as a high-rate and long-life anode material for lithium-ion batteries. The structure and morphology analysis of the as-prepared Sn@C nanocomposite shows that Sn nanoparticles with a size of about 8 nm are homogeneously dispersed in the spherical carbon matrix (denoted as Sn8@C). The Sn8@C nanocomposite exhibits an initial discharge capacity of 1007.1 mA h g-1 and maintains a reversible capacity of 910 mA h g-1 after 180 cycles at 200 mA g-1 (0.305 C). A capacity of 410 mA h g-1 was obtained after 1000 cycles at 4000 mA g-1 (6.1 C). Furthermore, the Sn8@C nanocomposite displays a charge-discharge capacity of 205.3 mA h g-1 at 16 000 mA g-1 (24.4 C). This high-rate performance is owing to the fact that the ultrasmall tin nanoparticles can effectively alleviate the absolute stress/strain during the lithiation/delithiation process and that the uniformly embedded nanoparticles in the stable carbon framework can accommodate the large volume change with a buffering effect to prevent Sn nanoparticles from aggregating.In this article, we report on the preparation of the pitaya-like Sn@C nanocomposite with an aerosol spray pyrolysis and its application as a high-rate and long-life anode material for lithium-ion batteries.

    Full Text Available The role of sexual or intrafamilial transmission of hepatitis C is controversial. A phylogenetic analysis was performed on the non-structural region 5B of the hepatitis C virus (NS5B-HCV. High percentages of homology (mean of 98.3% were shown between the couples. Twenty (83.3% of the 24 men but only two of the women (8.3% reported having had sexually transmitted diseases during their lives. The risk factors for HCV acquisition were blood transfusion (10 couples, use of illegal injected drugs (17, use of inhalants (15, acupuncture (5 and tattoos (5. The shared use of personal hygiene items included toothbrushes between six couples (25%, razor blades between 16 (66.7%, nail clippers between 21 (87.5% and manicure pliers between 14 (58.3%. The high degree of similarity of the hepatitis C virus genome supports the hypothesis of hepatitis C virus transmission between these couples.

    We present the results of spectroscopic measurements in the extreme ultraviolet regime (7-17 nm) of molten tin microdroplets illuminated by a high-intensity 3 J, 60 ns Nd:YAG laser pulse. The strong 13.5 nm emission from this laser-produced plasma (LPP) is of relevance for next-generation nanolithography machines. Here, we focus on the shorter wavelength features between 7 and 12 nm which have so far remained poorly investigated despite their diagnostic relevance. Using flexible atomic code calculations and local thermodynamic equilibrium arguments, we show that the line features in this region of the spectrum can be explained by transitions from high-lying configurations within the Sn{}8+-Sn{}15+ ions. The dominant transitions for all ions but Sn{}8+ are found to be electric-dipole transitions towards the n = 4 ground state from the core-excited configuration in which a 4p electron is promoted to the 5s subshell. Our results resolve some long-standing spectroscopic issues and provide reliable charge state identification for Sn LPP, which could be employed as a useful tool for diagnostic purposes.

    Cu-30% Nb in weighting were prepared by the method of Copper sintering liquid phase the method was improved by substitution of Nb power by Nb-H powder, obtaining a high density material with good mechanical properties, which was reduced to fine. Wire, Without heat treatment. The Cu-Nb 3 Sn wires were obtained by external diffusion process depositing tin in the Cu-30%Nb wires, and by internal diffusion process using the Sn-8.5% Cu in weighting, which was reduced to rods of 3.5 mm. These Cu-30%Nb rods were enclosed in copper tubes and deformed mechanically by rotary swaging and drawing. During the drawing step some wires were fractured, that were analysed and correlated with the microstructure of the Sn-8.5 Wt% Cu alloy. External and internal diffusion samples; after a fast thermal treatment for Sn diffusion, were submited to the temperature of 700 0 C to provide the reaction between Sn and Nb, leading to the Nb 3 Sn phase. Samples with several reaction times, and its influence on T c and J c critical parameters and normal resistivity were prepared and analysed. (author) [pt

    2013-02-01

    We report the label-free detection and sizing of the smallest individual RNA virus, MS2 by a spherical microcavity. Mass of this virus is ~6 ag and produces a theoretical resonance shift ~0.25 fm upon adsorbing an individual virus at the equator of the bare microcavity, which is well below the r.m.s background noise of 2 fm. However, detection was accomplished with ease (S/N = 8, Q = 4x105) using a single dipole stimulated plasmonic-nanoshell as a microcavity wavelength shift enhancer. Analytical expressions based on the "reactive sensing principle" are developed to extract the radius of the virus from the measured signals. Estimated limit of detection for these experiments was ~0.4 ag or 240 kDa below the size of all known viruses, largest globular and elongated proteins [Phosphofructokinase (345 kDa) and Fibrinogen (390 kDa), respectively].

    Describes the ash disposal technology of the Gacko lignite fired power plant in Yugoslavia. The ash has a high content of chemically active CaO (48.9%), a pH value of 12 and shows high exothermal reactions on contact with water. Ash lime slaking before disposal at the dumping site is therefore required. The ash slaking technology consists of ash transport from the power plant by container trucks to an ash conditioning installation (ash agitation with water) and hydraulic pipe transport of the ash slurry to the Drazljevo dumping site. 7 refs.

    1986-10-01

    It is known that macrophages play an important role in the removal of foreign particulate matter from tissue. When powdered dental amalgam is introduced into the soft tissues an amalgam tattoo is formed due to the intracellular degradation of amalgam by macrophages and their polykaryons. It was therefore feasible to study the effects of particulate amalgams as well as their individual phases on macrophages in vitro. The parameters compared were rate of the phagocytosis, changes of cellular morphology, and release of lactate dehydrogenase (LDH) to demonstrate plasma membrane permeability. It was shown that all the alloys except the Sn8Hg particles (gamma 2-phase) and gamma 2-containing Revalloy were effectively phagocytized by macrophages, and the alterations in cellular morphology were slight during the first day. Prominent cellular damage was seen in cultures treated with particulate Ag2Hg3 (gamma 1-phase) and Revalloy for 1 week. A slight increase in LDH activity in the medium was seen one hour after the alloy treatment. The LDH activities due to the amalgam treatment increased in the order Dispersalloy less than Revalloy less than Sybraloy. Intraperitoneal phagocytosis did not cause any morphological changes in macrophages, but the per cent of phagocytosis was diminished.

    Full Text Available The study presents the possibility of TDGA method based on multipoint measurement of temperature during crystallization of two test castings poured from different temperature. Sample castings have conical shape. Temperature measurement is carried out in six cone cross-sections between the heat axis and the surface of the mould cavity. The multichannel recording device allows describing the thermal derivative after time and direction. Presented examples of the assessment of kinetics of crystallization for alloys: AlSi11, CuSn8 and GJL 200 cast iron. Based on quantitative analysis of the microstructure (DAS, fig. 1 and tab.1 examples of relations were prepared, describing the mechanical and structural properties in function of crystallization kinetics parameters - DAS = f(vchł DAS = f(Δ(dT/dt/dt HV = f(Gy Rm = f(Δ(dT/dt/dt as shown in fig. 2 and 4. The evaluation of crystallization process was also conducted for AlSi11 skeleton castings. Pointed out was the universality of the method with respect to the mathematical interpretation of the results and its limitations due to data registration extracted from multiple thermocouples. Based on the conducted studies, the method can be applied in the industry as well as in the experimental practice.

    Full Text Available Investigations of Ni-Bi-Sn system were performed in order to inquire the phase diagram and to assess some diffusion kinetic parameters. For this purpose diffusion couples consisting of solid nickel (preliminary electroplated with tin and liquid Bi-Sn phase were annealed at 370 °C. Three compositions (0.8, 0.6 and 0.4 mole fractions Sn of the Bi-Sn melts were chosen. Annealing times from 24 to 216 h were applied. The phase and chemical compositions of the contact zone were determined by means of electron scanning microscope. It was confirmed that the diffusion layers consist mainly of Ni3Sn4 but other intermetallic phases grow as well. For the first time metastable Ni-Sn phases as NiSn and NiSn8 (NiSn9 were observed in metallurgical alloys (i.e. not in electroplated samples. The existence of a ternary compound previously reported in the literature was confirmed. More than one ternary Ni-Bi-Sn compounds might possibly be admitted. A growth coefficient of (2.29 ± 0.02 x 10-15 m2 s-1 was obtained. It was found that the apparent activation energy for diffusion layers growth (18 ± 8 kJ mol-1 is inferior to that one assessed at growth from solid state Bi-Sn mixtures (88 ± 12 kJ mol-1.

    We employ a combination of ion mobility measurements and an unbiased systematic structure search with density functional theory methods to study structure and energetics of gas phase tin cluster cations, Sn(n)(+), in the range of n = 3-15. For Sn(13)(+) we also carry out trapped ion electron diffraction measurements to ascertain the results obtained by the other procedures. The structures for the smaller systems are most easily described by idealized point group symmetries, although they are all Jahn-Teller distorted: D(3h) (trigonal bipyramid), D(4h) (octahedron), D(5h) (pentagonal bipyramid) for n = 5, 6, and 7. For the larger systems we find capped D(5h) for Sn(8)(+) and Sn(9)(+), D(3h) (tricapped trigonal prism) and D(4d) (bicapped squared antiprism) plus adatoms for n = 10, 11, 14, and 15. A centered icosahedron with a peripheral atom removed is the dominant motif in Sn(12)(+). For Sn(13)(+) the calculations predict a family of virtually isoenergetic isomers, an icosahedron and slightly distorted icosahedra, which are about 0.25 eV below two C(1) structures. The experiments indicate the presence of two structures, one from the I(h) family and a prolate C(1) isomer based on fused deltahedral moieties.

  20. New Cu-Free Ti-Based Composites with Residual Amorphous Matrix

    Full Text Available Titanium-based bulk metallic glasses (BMGs are considered to have potential for biomedical applications because they combine favorable mechanical properties and good biocompatibility. Copper represents the most common alloying element, which provides high amorphization capacity, but reports emphasizing cytotoxic effects of this element have risen concerns about possible effects on human health. A new copper-free alloy with atomic composition Ti42Zr10Pd14Ag26Sn8, in which Cu is completely replaced by Ag, was formulated based on Morinaga’s d-electron alloy design theory. Following this theory, the actual amount of alloying elements, which defines the values of covalent bond strength Bo and d-orbital energy Md, situates the newly designed alloy inside the BMG domain. By mean of centrifugal casting, cylindrical rods with diameters between 2 and 5 mm were fabricated from this new alloy. Differential scanning calorimetry (DSC and X-rays diffraction (XRD, as well as microstructural analyses using optical and scanning electron microscopy (OM/SEM revealed an interesting structure characterized by liquid phase-separated formation of crystalline Ag, as well as metastable intermetallic phases embedded in residual amorphous phases.

    The chemopreventive actions of vitamin D were examined in the N-nitroso-tris-chloroethylurea (NTCU) mouse model, a progressive model of lung squamous cell carcinoma (SCC). SWR/J mice were fed a deficient diet (D) containing no vitamin D3, a sufficient diet (S) containing 2000 IU/kg vitamin D3, or the same diets in combination with the active metabolite of vitamin D, calcitriol (C) (80 μg/kg, weekly). The percentage (%) of the mucosal surface of large airways occupied by dysplastic lesions was determined in mice after treatment with a total dose of 15 or 25 μmol NTCU (N). After treatment with 15 μmol NTCU, the % of the surface of large airways containing high-grade dysplastic (HGD) lesions were vitamin D-deficient +NTCU (DN), 22.7 % (p<0.05 compared to vitamin D-sufficient +NTCU (SN)); DN + C, 12.3%; SN, 8.7%; and SN + C, 6.6%. The extent of HGD increased with NTCU dose in the DN group. Proliferation, assessed by Ki-67 labeling, increased upon NTCU treatment. The highest Ki-67 labeling index was seen in the DN group. As compared to SN mice, DN mice exhibited a 3-fold increase (p <0.005) in circulating white blood cells (WBC), a 20% (p <0.05) increase in IL-6 levels, and a 4 -fold (p <0.005) increase in WBC in bronchial lavages. Thus, vitamin D repletion reduces the progression of premalignant lesions, proliferation, and inflammation, and may thereby suppress development of lung SCC. Further investigations of the chemopreventive effects of vitamin D in lung SCC are warranted. PMID:26276745

    2009-01-01

    The ribosomal protein L10 (RP L10) is a strong candidate to be included in the class of tumor suppressor proteins. This protein, also denominated as QM, is known to participate in the binding of ribosomal subunits 60S and 40S and the translation of mRNAs. It has a molecular weight that varies between 24 and 26 kDa and an isoelectric point of (pI) 10.5. The sequence of the protein QM is highly conserved in mammals, plants, invertebrates, insects and yeast which indicates its critical functions in a cell. As a tumor suppressor, RP L10 has been studied in strains of Wilm's tumor (WT-1) and tumor cells in the stomach, where was observed a decrease in the amount of its mRNA. More recently, the RP L10 was found in low amounts in the early stages of prostate adenoma and showed some mutation in ovarian cancer, what indicates its role as a suppressor protein in the development of these diseases. It has also been described that this protein interacts with c-Jun and c-Yes inhibiting growth factors and consequently, cell division. This work has an important role on the establishment of soluble expression of QM to give base information for further studies on expression that aim to evaluate the specific regions where it acts binding the 60S and 40S ribosomal subunits and translation, as well as its binding to proto-oncogenes. The cDNA for QM protein was amplified by PCR and cloned into periplasmic expression vector p3SN8. The QM protein was expressed in E. coli BL21 (DE3) in the region of cytoplasm and periplasm, the best condition was obtained from the expression of the recombinant plasmid QM p1813 Q M at 25 degree C or 30 degree C, the soluble protein was obtained with small amounts of contaminants. The assays of secondary structure showed that the QM protein is predominantly alpha-helix, but when it loses the folding, this condition changes and the protein is replaced by β- sheet feature.

    Pulsed-beam measurements have been recently performed at the XTU-tandem of the National Laboratory of Legnaro with the aim to investigate short-lived isomeric states in neutron-deficient nuclei of the A∼130 region. Isotopically enriched tin targets were irradiated with a 70 MeV 16 O beam (pulse width of 3 ns at a repetition rate of 800 ns) and the γ-ray angular distributions perturbed in magnetic or electric interaction were observed time-differentially. Static electromagnetic moments were thus determined for several known short-lived isomers in 129,130,131 Ce and 129 Ba. In these experiments a new isomeric decay has been also identified and its properties are reported in the present work. The isomer has been observed on a target containing 116 Sn (87%), 117 Sn (8%) and 118 Sn (5%). The tin target of 0.6 mg/cm 2 thickness evaporated on a Pb foil was placed in an external magnetic field of 32 kG whose orientation was periodically reversed. Two planar HPGe detectors positioned at ±135 deg. with respect to the beam direction were used for the γ-ray detection. In the delayed spectra a γ-ray of 105.2 keV has been observed and a half-life of 32(5)ns has been determined for it. The experimental and calculated R(t) modulation ratios of the 105.2 keV γ-ray in the external magnetic field are given. From the derived Larmor frequency a value g = + 0.48(3) has been determined for the isomeric state g-factor. A dipole character has been established for the delayed 105.2 keV γ-transition based on the determined negative A 2 coefficient. The new isomer was tentatively assigned to the odd-odd 130 La populated in the 116,117,118 Sn ( 16 O,pxn) reaction. In this nucleus a state at (150.3 + x) keV de-excited by a 105.2 keV transition is known and it was identified with the isomer. Further experiments are in progress for the definite assignment and the elucidation of the isomer configuration. (authors)

    In this work we evaluate the composition of a bronze alloy using X-ray fluorescence spectrometry (XRF) and Monte Carlo (MC) simulations. For this purpose, a 7th Century BC archeological vase from the SW Iberian Peninsula, displaying a well formed corrosion patina was analyzed by means of a portable X-ray fluorescence spectrometer. Realistic MC simulations of the experimental setup were performed with the XRMC code package which is based on an intensive use of variance-reduction techniques and uses XRAYLIB a constantly updated X-ray library of atomic data. A single layer model was applied for simulating XRF of polished/pristine bronze whereas a two-or-three-layer model was developed for bronze covered respectively by a corrosion patina alone or coupled with a superficial soil derived crust. These simulations took into account corrosion (cerussite (PbCO{sub 3}), cuprite (Cu{sub 2}O), malachite (Cu{sub 2}CO{sub 3}(OH){sub 2}), litharge (PbO)) and soil derived products (goethite (FeO(OH)) and quartz (SiO{sub 2})) identified by means of X-ray diffraction and Raman micro analytical techniques. Results confirm previous research indicating that the XRF/Monte Carlo protocol is well suited when a two-layered model is considered, whereas in areas where the patina + soil derived products' crust is too thick, X-rays from the alloy substrate are not able to exit the sample. Quantitative results based on MC simulations indicate that the vase is made of a lead–bronze alloy: Mn (0.2%), Fe (1.0%), Cu (81.8%), As (0.5%), Ag (0.6%), Sn (8.0%) and Pb (8.0%). - Highlights: • We study an archeological bronze vase with patina corrosion using XRF spectrometry. • The experimental setup is modeled using Monte Carlo (MC) simulations. • Combining MC simulations with XRF it is possible to derive concentrations. • We demonstrated that this is possible without removing the patina.

    This article reports an experimental and theoretical investigation of mercury dissolution from dental amalgams immersed in neutral (noncorrosive) and acidic (corrosive) flows. Atomic absorption spectrophotometric measurements of Hg loss indicate that in neutral flow, surface oxide films formed in air prior to immersion persist and effectively suppress significant mercury release. In acidic (pH 1) flows, by contrast, oxide films are unstable and dissolve; depending on the amalgam’s material composition, particularly its copper content, two distinct mercury release mechanisms are initiated. In low copper amalgam, high initial mercury release rates are observed and appear to reflect preferential mercury dissolution from unstable Sn8Hg ( γ 2) grains within the amalgam matrix. In high copper amalgam, mercury release rates are initially low, but increase with time. Microscopic examination suggests that this feature reflects corrosion of copper from grains of Cu6Sn5 ( η') and consequent exposure of Ag2Hg3 ( γ 1) grains; the latter serve as internal mercury release sites and become more numerous as corrosion proceeds. Three theoretical models are proposed in order to explain observed dissolution characteristics. Model I, applicable to high and low copper amalgams in neutral flow, assumes that mercury dissolution is mediated by solid diffusion within the amalgam, and that a thin oxide film persists on the amalgam’s surface and lumps diffusive in-film transport into an effective convective boundary condition. Model II, applicable to low copper amalgam in acidic flow, assumes that the amalgam’s external oxide film dissolves on a short time scale relative to the experimental observation period; it neglects corrosive suppression of mercury transport. Model III, applicable to high copper amalgam in acidic flow, assumes that internal mercury release sites are created by corrosion of copper in η' grains and that corrosion proceeds via an oxidation-reduction reaction

    Full Text Available Introduction: Hyperechogenicity of the substantia nigra (SN+ is a risk marker for Parkinson’s disease (PD which can be detected before the diagnosis. In healthy individuals, SN+ has been associated with slight deficits in specific cognitive functions, suggesting cognitive impairment as a possible pre-diagnostic marker for PD. However, the pattern of cognitive deficits associated with SN+ has not yet been compared with those present in PD.Methods: Data of 262 healthy individuals with normal echogenicity (SN- and 48 healthy individuals with SN+ were compared with 82 early stage PD patients using the Consortium to Establish a Registry for Alzheimer’s disease test battery. First, the test clusters (factors were identified using a principal component analysis (PCA. Mean group performance of cognitive tests belonging to distinct factors, according to the PCA, and single subtest performances were compared using analyses of variance. Second, the number of individuals with abnormal cognitive performances (z-score <-1.0 were compared between groups. Results: Verbal memory, semantic and executive function, and praxis were identified as components of cognitive performances. The SN+ group performed significantly worse than the SN- group in tests assessing semantic and executive function, with a non-significant decrease in verbal memory. On the subtest level, individuals of the SN+ group scored significantly lower than the SN- group on the Boston Naming Test (BNT (p=0.008. In all subtests, the percentages of PD patients with values below the cut-off for abnormal performance were higher than in the SN- group. Moreover, more individuals from the SN+ group scored below the cut-off in the BNT (SN-=8.4%, SN+=20.8%, p=0.01 and TMT-B (SN-=6.9%, SN+=16.7%, p=0.02, compared to the SN- group. Conclusion: This study confirms poorer performance of healthy individuals with SN+ compared to SN- in specific cognitive domains. However, against the SN- group, the cognitive

    The ribosomal protein L10 (RP L10) is a strong candidate to be included in the class of tumor suppressor proteins. This protein, also denominated as QM, is known to participate in the binding of ribosomal subunits 60S and 40S and the translation of mRNAs. It has a molecular weight that varies between 24 and 26 kDa and an isoelectric point of (pI) 10.5. The sequence of the protein QM is highly conserved in mammals, plants, invertebrates, insects and yeast which indicates its critical functions in a cell. As a tumor suppressor, RP L10 has been studied in strains of Wilm's tumor (WT-1) and tumor cells in the stomach, where was observed a decrease in the amount of its mRNA. More recently, the RP L10 was found in low amounts in the early stages of prostate adenoma and showed some mutation in ovarian cancer, what indicates its role as a suppressor protein in the development of these diseases. It has also been described that this protein interacts with c-Jun and c-Yes inhibiting growth factors and consequently, cell division. This work has an important role on the establishment of soluble expression of QM to give base information for further studies on expression that aim to evaluate the specific regions where it acts binding the 60S and 40S ribosomal subunits and translation, as well as its binding to proto-oncogenes. The cDNA for QM protein was amplified by PCR and cloned into periplasmic expression vector p3SN8. The QM protein was expressed in E. coli BL21 (DE3) in the region of cytoplasm and periplasm, the best condition was obtained from the expression of the recombinant plasmid QM p1813{sub Q}M at 25 degree C or 30 degree C, the soluble protein was obtained with small amounts of contaminants. The assays of secondary structure showed that the QM protein is predominantly alpha-helix, but when it loses the folding, this condition changes and the protein is replaced by {beta}- sheet feature.

  13. From Stable ZnO and GaN Clusters to Novel Double Bubbles and Frameworks

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available A bottom up approach is employed in the design of novel materials: first, gas-phase “double bubble” clusters are constructed from high symmetry, Th, 24 and 96 atom, single bubbles of ZnO and GaN. These are used to construct bulk frameworks. Upon geometry optimization—minimisation of energies and forces computed using density functional theory—the symmetry of the double bubble clusters is reduced to either C1 or C2, and the average bond lengths for the outer bubbles are 1.9 Å, whereas the average bonds for the inner bubble are larger for ZnO than for GaN; 2.0 Å and 1.9 Å, respectively. A careful analysis of the bond distributions reveals that the inter-bubble bonds are bi-modal, and that there is a greater distortion for ZnO. Similar bond distributions are found for the corresponding frameworks. The distortion of the ZnO double bubble is found to be related to the increased flexibility of the outer bubble when composed of ZnO rather than GaN, which is reflected in their bulk moduli. The energetics suggest that (ZnO12@(GaN48 is more stable both in gas phase and bulk frameworks than (ZnO12@(ZnO48 and (GaN12@(GaN48. Formation enthalpies are similar to those found for carbon fullerenes.

    This work studied the potential use of the waste from Eucalyptus globulus and Eucalyptus nitens as energy crops, evaluating young and adult stages of both in all four seasons of the year with different moisture contents. The study was carried out made in Cantabria (North coast of Spain), located at latitude 43{sup o}28'N, and longitude 3{sup o}48'W. In this region, 29,513ha are dedicated to the growth of Eucalyptus, with about 80% E. globulus, and 20% E. nitens. Six different plantations have been analyzed and their bioclimatic diagrams determined. After the collection of samples the potential energy of every sample was obtained, they were weighed, analyzed and burned, giving a mean net calorific value of 17,384 and 17,927kJ/kg in the adult stage of E. globulus and E. nitens, respectively. The results for the young stage of both species were 17,708 and 18,670kJ/kg. Moisture content in the samples has a great influence on power production.

The general formulas: [Cu4 DAPsc2(tpmc2]ClO48·5CH3COCH3·H2O and [Cu2 DAPtsc2(tpmc](ClO44·7C2H5OH were proposed on the basis of elemental analyses and conductometric measurements. The complexes were characterized by magnetic measurement, electronic absorption and IR spectroscopy. For the dinuclear complex, an exo coordination of Cu(II with four nitrogens from tpmc and m-bonded DAPtsc2 through sulfurs and possibly terminal hydrazinic (azomethine nitrogens is assumed. For the tetranuclear complex, it is supposed that one DAPsc2 bridges two [Cu2 tpmc]4+ units using oxygens and terminal hydrazinic nitrogens as ligators. Finally, some antibacterial activity of the complexes was found.

    We have investigated various magnetic quantities of a system consisting of conduction electrons coupled to localized spins. In obtaining the magnetic state equations (which relate the ionic and electronic magnetisations to temperature and the model parameters) we have adopted the molecular field approximation. This simple model is of interest to the magnetism of the heavy rare earth intermettallics. For these systems the localized spin is that of the 4f shell; it is described by the parameters g (the Lande's factor) and J (the total angular momentum of the 4f electrons in the ground state). We derive an analytical linear relation between the critical temperature and The Gennes Factors J(J+1)(g-1) which is experimentally observed for RAl 2 . A fitting between the experimental points and the theoretical prediction gives for the exchange parameter the value J o = 48.6 meV. We have also performed a parametric study of the model, using a rectangular energy density of states. The results are shown on tables and diagrams. (author) [pt

    Observations of D/H in the local interstellar medium (Moos et al. 2002) reveal a constant D/H ratio of (1.52 +/- 0.08) x 10-5, however there is a large scatter in the D/H ratio for stars located outside the local bubble (d >= 200pc; Moos et al. 2002; Hoopes et al. 2003). We report on our Far Ultraviolet Spectroscopic Explorer observations of the subdwarfs LB 3241 [(l, b) = (273.o7, -62.o48); d = 610 pc] and PG 0952+519 [(l, b) = (164.o07, +49.o01); d = 530 pc]. Numerous interstellar lines of D 1, O 1, N 1, Fe 2, and P 2 are detected. We present the results of our combined curve-of-growth and profile fitting methods for all species are presented. At distances of 500-600pc these subdwarfs are located well outside the local bubble. Although values of H 1 are unavailable, we present D/N and D/O which enable further constraints to be placed on the variability of D 1 outside the local bubble. This work is based on data obtained for the Guaranteed Time Team by the NASA-CNES-CSA FUSE mission. Financial support has been provided by NASA contract NAS5-32985.

    Exposure to particles of high energy and charge (HZE particles) can produce decrements in cognitive performance. A series of experiments exposing rats to different HZE particles was run to evaluate whether the performance decrement was dependent on the age of the subject at the time of irradiation. Fischer 344 rats that were 2-, 11- and 15/16-months of age were exposed to 16 O, 48 Ti, or 4 He particles at the NASA Space Radiation Laboratory at Brookhaven National Laboratory. As previously observed following exposure to 56 Fe particles, exposure to the higher LET 48 Ti particles produced a disruption of cognitive performance at a lower dose in the older subjects compared to the dose needed to disrupt performance in the younger subjects. There were no age related changes in the dose needed to produce a disruption of cognitive performance following exposure to lower LET 16 O or 4 He particles. The threshold for the rats exposed to either 16 O or 4 He particles was similar at all ages. Because the 11- and 15-month old rats are more representative of the age of astronauts (45-55 years old) the present results indicate that particle LET may be a critical factor in estimating the risk of developing a cognitive deficit following exposure to space radiation on exploratory class missions.

  2. Ferromagnetism in Gd doped ZnO nanowires: A first principles study

    2014-12-19

    In several experimental studies, room temperature ferromagnetism in Gd-doped ZnO nanostructures has been achieved. However, the mechanism and the origin of the ferromagnetism remain controversial. We investigate the structural, magnetic, and electronic properties of Zn 48O48 nanowires doped with Gd, using density functional theory. Our findings indicate that substitutionally incorporated Gd atoms prefer occupying the surface Zn sites. Moreover, the formation energy increases with the distance between Gd atoms, signifying that no Gd-Gd segregation occurs in the nanowires within the concentration limit of ≤2%. Gd induces ferromagnetism in ZnO nanowires with magnetic coupling energy up to 21 meV in the neutral state, which increases with additional electron and O vacancy, revealing the role of carriers in magnetic exchange. The potential for achieving room temperature ferromagnetism and high TC in ZnO:Gd nanowires is evident from the large ferromagnetic coupling energy (200 meV) obtained with the O vacancy. Density of states shows that Fermi level overlaps with Gd f states with the introduction of O vacancy, indicating the possibility of s-f coupling. These results will assist in understanding experimental findings in Gd-doped ZnO nanowires.

The beach and coastal area is influenced by wave energy from the West and North directions The purpose of this study is to analyze the relationship between the zone of sediment accumulation of empirical approaches on oceanography parameter containing rare earth elements. The approach used is to predict the shore wave energy using wave prediction curve deep waters to obtain the energy flux of the wave at each point of reference. Sediments containing rare earth elements tend to lead to the south as a result of the movement of longshore currents. Regional coastal area of the western part of the island of Belitung, especially in the southern part of the estuary of the river Tanjung Pandan is estimated to be a zone of sediment accumulation. The movement of sediment caused by wave energy from the north led to sedimentation evolved significantly in the south which is thought to contain rare earths minerals derived from land. This sedimentation process takes place on a seasonal basis, which allegedly took place in the west. The movement of sediment to the south of the mouth of the Cerucuk River it is predicted that rare earth elements were supplied from these rivers tend to settle in the southern part of the estuary Cerucuk throughout the year.

    Trilithium aluminium trimolybdate(VI), Li(3)Al(MoO(4))(3), has been grown as single crystals from α-Al(2)O(3) and MoO(3) in an Li(2)MoO(4) flux at 998 K. This compound is an example of the well known lyonsite structure type, the general formula of which can be written as A(16)B(12)O(48). Because this structure can accomodate cationic mixing as well as cationic vacancies, a wide range of chemical compositions can adopt this structure type. This has led to instances in the literature where membership in the lyonsite family has been overlooked when assigning the structure type to novel compounds. In the title compound, there are two octahedral sites with substitutional disorder between Li(+) and Al(3+), as well as a trigonal prismatic site fully occupied by Li(+). The (Li,Al)O(6) octahedra and LiO(6) trigonal prisms are linked to form hexagonal tunnels along the [100] axis. These polyhedra are connected by isolated MoO(4) tetrahedra. Infinite chains of face-sharing (Li,Al)O(6) octahedra extend through the centers of the tunnels. A mixed Li/Al site, an Li, an Mo, and two O atoms are located on mirror planes.

    Pyrolysis of AMP/SiO2 adsorbed Cs (AMP-Cs/SiO2) occurred at > 400 °C sintering temperature, and Cs immobilisation decreased from 100% to 40% after sintering at 1200 °C. To safely dispose radioactive Cs, allophane was immobilized with AMP-Cs/SiO2 to prepare a stable form by using a pressing/sintering method. The structure of AMP-Cs/SiO2 collapsed, and cesium aluminosilicate formed more easily under conditions of higher sintering temperature (>800 °C) or increasing mixing ratio of allophane (mass ratio = 1:3 AMP-Cs/SiO2-allophane). The decomposition products of AMP-Cs/SiO2 were Cs2O, MoO3 and P2O5 at 1200 °C. Cs2O volatilisation was depressed by allophane addition, and a stable immobilisation phase of Cs4Al4Si20O48 formed. An immobilisation ratio of Cs of approximately 100% was maintained. The leachability of Cs for AMP-Cs/SiO2-allophane (1:3, 1200 °C) in distilled water at 25 °C and 90 °C for 15 days was estimated as 0.174% and 1.55%, respectively.

    A new moving group comprising at least four Blue Horizontal Branch (BHB) stars is identified at (l; b) = (65{sup o}; 48{sup o}). The horizontal branch at g{sub 0} = 18.9 magnitude implies a distance of 50 kpc from the Sun. The heliocentric radial velocity is = -157 {+-} 4 km s{sup -1}, corresponding to V{sub gsr} = -10 km s{sup -1}; the dispersion in line-of-sight velocity is consistent with the instrumental errors for these stars. The mean metallicity of the moving group is [Fe/H] {approx} -2.4, which is significantly more metal poor than the stellar spheroid. We estimate that the BHB stars in the outer halo have a mean metallicity of [Fe/H]=-2.0, with a wide scatter and a distribution that does not change much as a function of distance from the Sun. We explore the systematics of SDSS DR7 surface gravity metallicity determinations for faint BHB stars, and present a technique for estimating the significance of clumps discovered in multidimensional data. This moving group cannot be distinguished in density, and highlights the need to collect many more spectra of Galactic stars to unravel the merger history of the Galaxy.

    Exposure to particles of high energy and charge (HZE particles) can produce decrements in cognitive performance. A series of experiments exposing rats to different HZE particles was run to evaluate whether the performance decrement was dependent on the age of the subject at the time of irradiation. Fischer 344 rats that were 2-, 11- and 15/16-months of age were exposed to 16O, 48Ti, or 4He particles at the NASA Space Radiation Laboratory at Brookhaven National Laboratory. As previously observed following exposure to 56Fe particles, exposure to the higher LET 48Ti particles produced a disruption of cognitive performance at a lower dose in the older subjects compared to the dose needed to disrupt performance in the younger subjects. There were no age related changes in the dose needed to produce a disruption of cognitive performance following exposure to lower LET 16O or 4He particles. The threshold for the rats exposed to either 16O or 4He particles was similar at all ages. Because the 11- and 15-month old rats are more representative of the age of astronauts (45-55 years old) the present results indicate that particle LET may be a critical factor in estimating the risk of developing a cognitive deficit following exposure to space radiation on exploratory class missions.

    To evaluate the clinical application of protein-to-creatinine ratio (P/Cr) in spot urine samples so as to check whether it can replace urine protein excretion in 24 h collections for the diagnosis and screening of preeclampsia. The investigators selected 100 cases of pregnant women with preeclampsia and 36 cases of normal pregnant women examined at Sir Run Run Shaw Hospital over the last two years. The correlations between P/Cr in first morning urine samples and urinary protein excretion in 24 h collections were analyzed. The cutoff values of P/Cr in first morning urine samples for screening preeclampsia of 0.3 g and 5 g in urinary protein excretion in 24 h collections were determined by a receiver operating characteristics (ROC) curve. A highly significant correlation existed between P/Cr in first morning urine samples and urinary protein excretion in 24 h collections. By the ROC curve analysis, the P/Cr of 0.34 g/g and 2.08 g/g in first morning urine samples represented the most appropriate threshold for detecting the urinary protein excretion of 0.3 g and 5 g in 24 h collections. The P/Cr in spot urine samples can replace urinary protein excretion in 24 h collections. It is a simple and reliable tool of diagnosis and follow-up for preeclampsia.

    Unmet family planning is one of the common causes for low contraceptive prevalence rate in developing countries including Ethiopia. Thus, this study designed to assess the prevalence and associated factors of unmet need in Shire Endaslassie town, Northern west of Tigray, Ethiopia. A community based cross sectional study design was employed. Multistage sampling technique was employed and data were collected using a semi-structured questionnaire by interviewer administered technique. Questionnaires were reviewed and checked for completeness, accuracy and consistency. Reviewed data were entered to Epi info 7 and analyzed by SPSS version 20 statistical software. Variables with P-value of less than 0.2 in bivariate analyses were entered for multivariate analysis and AOR at 95% CI with p-value of less than 0.05 were considered as significant variables. The overall unmet need for family planning in the study area was 109(21.4%). 74(14.5%) for spacing and 35(6.9%) for limiting. Age group of 35-39 and >=40 (AOR= 2.7,95%CI:1.1,6.5), (AOR = 2.65, 95%CI:1.10, 6.40) respectively, decided numbers of desired children more than five (AOR = O.48, 95%CI: 0.28, 0.80), discussions of client with heath care providers (AOR = 6.32, 95%CI: 2.56, 15.58), previous use of modern family planning (AOR = 2.29, 95%CI, 1.20, 4.34) were significantly associated with unmet need for family planning. Unmet need for family planning in the study area was high, so continuous discussion on modern family planning with community health workers and encouraging of women to decide desired numbers of children of less than five in general are better to be strengthened.

    106 patients, 114 W, 27 M, were thyroidectomized for differentiated thyroid cancer (follicular 29.3% - papillary 54.3%) with different stages of gravity (N O: 48.2% - N 1: 32.8% - N 2: 19%). Neck dissection was used in cases of involved nodes. One or several doses of 131 I were given to 126 subjects, 106 patients were treated with L thyroxine (LT4) (mean daily dose: 2.5 {mu}g/kg BW). 23 patients presenting intolerance to LT4 with non suppressed TSH for 13 of them were treated by an association of tiratricol (TRIAC) + LT4. The follow up included a yearly check up involving clinical examination, plasma thyroglobulin (Tg) and thyroid stimulating hormone (TSH) assessment, neck ultrasonography and X ray of the chest. Therapy was stopped for 4 weeks in cases with Tg above its detectable value and a total body scan performed with Tg and TSH controls. The mean duration of follow up was 94.5 {+-} 67.7 months and extended to more than 5 years for 61% of the patients. We observed 22 relapses of the tumor with 4 deaths. Age less then 45 years, appears as the best factor of prognosis. 2 groups of patients were compared to evaluate the incidence of TSH suppression on the relapse free survival (group 1 n = 30 with a TSH {<=} 0.10 mU/1 and group 2 n = 15 with a TSH always > 1 mU/1 during the follow up). The relapse free survival was shorter in group 2 (p 0.01). Association of TRIAC with LT4 leads to a reduction of the daily dose of LT4 (m 25{mu}g/day) with a significant improvement of TSH suppression and clinical tolerance. In conclusion, TSH suppression improves the prognosis in thyroidectomized patients for differentiated carcinoma. Association of TRIAC with LT4 seems able to approve TSH suppression and therapeutic tolerance. (authors). 40 refs., 5 tabs.

    The present thesis deals with the spectroscopy of the gamma radiation from the reaction fragments after binary reactions in the systems 16 O + 27 Al, 48 Ti, and 58 Ni at incident energies from 90 to 100 MeV, i.e. far above the Coulomb threshold. ΔE-E telescopes, which were located at 35 0 to the beam direction, detected the projectile-like fragments and defined the reaction channel and the scattering plane. In coincidence to this the gamma quanta in a 120-cm 3 -Ge(Li)-diode and a 27 x 33-cm-NaI-spectrometer were observed. The gamma spectra are equal to those observed hitherto in fusion reactions except for the high energetic gamma lines from the ejectiles, which are raised from the gamma continuum of the heavy fragments. From the spectroscoped gamma radiation for the light as for the heavy fragments the excitation energy, the value of the fragment angular momentum, as well as the occupation of the magnetic sublevels could be determined. The hard projectile 16 O transfers the dissipated energy and the angular momentum transferred by the spin of the fragments nearly completely into the residue nucleus. The probability for the observation of a ground state transition in one of the heavy fragments extends to (0.85 +- 0.10) per carbon ejectile in the system 16 O + 48 Ti. The residue nucleus distribution corresponds to that expected by the statistical model from the decay of the compound-nucleus 52 Cr belonging to the ejectile 12 C, the excitation energy of which corresponds to the reaction Q-value.

    Beginning in the lower Triassic, intracratonic, basins are formed in the Westem Pampean Ranges region, San Juan province, Argentina. One of these basins, the Marayes-El Carrizal basin, extends in an approximate NNW-SSE direction along the entire western edge of the La Huerta range, between latitudes 31 o 15' - 31 o 48' South and longitudes 67 o 12'-67 o 3O' West. According to Ramos (1993), the initial facies of the synrift deposits (Marayes Group) that fill the mentioned basin, are associated with the emplacement of basaltic flows and sills, part of the residual activity of the Choiyoi Group. Bossi (1975), analyzes in detail the stratigraphy of the Marayes Group. lt consists of an interstratified sequence of continental clastic sediments of mid to upper Triassic age (based on paleontological and palinological evidences) including, in ascending stratigraphic order, the Esquina Colorada, Carrizal and Quebrada del Barro Formations. The only igneous component in this sequence is a basaltic body, referred to as Marayes Viejo Basalt (BMV), located in the area known as Marayes Viejo in the extreme southem part of the La Huerta range, at approximately 31 o 25' South Latitude and 67 o 22' West Longitude. He describes the body as an 'elongated oval shaped dike that intrudes the Esquina Colorada Formation and whose age is uncertain because is an intrusive body'. More recently, Castro de Machuca et al. (1998), identify in the same area a small hypabisal body of andesitic composition, the Marayes Viejo Porphry (PNW), whose radiometric age (259±3 Ma) permits assigning to the Neopaleozoic. The absolute age of the BMV presentes in this work, confirms the spatial relationships observed between the different lithostratigraphic units, and supports the conclusion that the magmatic activity in the area is initiated in the Neopaleozoic, prior to the formation and filling of the Marayes-El Carrizal basin (au)

    Extreme precipitation events, and the quantitative precipitation forecasts (QPFs) associated with them, are examined. The study uses data from the Hydrometeorology Testbed (HMT), which conducted its first field study in California during the 2005/06 cool season. National Weather Service River Forecast Center (NWS RFC) gridded QPFs for 24-h periods at 24-h (day 1), 48-h (day 2), and 72-h (day 3) forecast lead times plus 24-h quantitative precipitation estimates (QPEs) fromsites in California (CA) and Oregon-Washington (OR-WA) are used. During the 172-day period studied, some sites received more than 254 cm (100 in.) of precipitation. The winter season produced many extreme precipitation events, including 90 instances when a site received more than 7.6 cm (3.0 in.) of precipitation in 24 h (i.e., an "event") and 17 events that exceeded 12.7 cm (24 h)-1 [5.0 in. (24 h)-1]. For the 90 extreme events f.7.6 cm (24 h)-1 [3.0 in. (24 h)-1]g, almost 90% of all the 270 QPFs (days 1-3) were biased low, increasingly so with greater lead time. Of the 17 observed events exceeding 12.7 cm (24 h)-1 [5.0 in. (24 h)-1], only 1 of those events was predicted to be that extreme. Almost all of the extreme events correlated with the presence of atmospheric river conditions. Total seasonal QPF biases for all events fi.e., $0.025 cm (24 h)-1 [0.01 in. (24 h)-1]g were sensitive to local geography and were generally biased low in the California-Nevada River Forecast Center (CNRFC) region and high in the Northwest River Forecast Center(NWRFC) domain. The low bias in CA QPFs improved with shorter forecast lead time and worsened for extreme events. Differences were also noted between the CNRFC and NWRFC in terms of QPF and the frequency of extreme events. A key finding from this study is that there were more precipitation events .7.6 cm (24 h)-1 [3.0 in. (24 h)21] in CA than in OR-WA.

    2002-01-01

    To investigate the relationship between obesity, small-solute clearances, and nutrition in continuous peritoneal dialysis (CPD), we compared clearances and nutrition indices between 270 obese and 502 normal-weight CPD patients. Degree of obesity was classified by the ratio of body weight (W) to desired weight (DW) at the first clearance study. The DWs were obtained from the tables of the Metropolitan Life Insurance Company, assuming a medium skeletal frame. The obese patients (group I) had W/DW > 1.2 (1.38 +/- 0.17), and the normal-weight patients (group II) had 0.9 W/DW W and DW. The following variables differed between group I (first value) and group II: sex (women: 48.2% vs. 33.9%), W (87.6 +/- 14.4 kg vs. 68.2 +/- 8.7 kg), body surface area (1.95 +/- 0.22 m2 vs. 1.77 +/- 0.16 m2), body water by method of Watson (41.2 +/- 7.7 L vs. 36.3 +/- 5.5 L), body mass index (31.8 +/- 3.9 vs 24.3 +/- 2.0), protein nitrogen appearance (PNA: 62.9 +/- 17.6 kg in 24 h vs. 57.7 +/- 15.7 kg in 24 h), PNA normalized to DW (1.08 +/- 0.29 g/kg in 24 h vs. 0.96 +/- 0.26 g/kg in 24 h), creatinine excretion (CrEx: 1111 +/- 396 mg in 24 h vs. 991 +/- 348 mg in 24 h), CrEx/W (12.6 +/- 3.7 g/kg in 24 h vs. 15.4 +/- 4.5 g/kg in 24 h), CrEx/DW (17.3 +/- 5.3 g/kg in 24 h vs. 15.1 +/- 4.8 g/kg in 24 h), lean body mass (LBM: 49.3 +/- 13.8 kg vs. 43.6 +/- 11.9 kg), LBM/W (0.56 +/- 0.12 vs. 0.64 +/- 0.15), and LBM/DW (0.77 +/- 0.18 vs 0.67 +/- 0.16), all at p p > 0.05) were found in the diabetes prevalence (53.0% vs. 40.8%), height (165.9 +/- 11.7 cm vs. 167.4 +/- 9.8 cm), and serum albumin (3.64 +/- 0.55 g/dL vs. 3.53 +/- 0.62 g/dL). No differences were found in age, duration of CPD until the first clearance study, percent of subjects with anuria, Kt/V urea, creatinine clearance, blood urea nitrogen, serum creatinine, and PNA normalized to W. Obese CPD patients tend to have better nutrition indices than do normal-weight CPD patients with similar small-solute clearances. In obese subjects

    Full Text Available O presente trabalho verificou experimentalmente a ecologia da polinização da amoreira-preta (Rubus sp.. Objetivou-se confirmar a síndrome de polinização de Rubus sp., por meio de análise de seu sistema reprodutivo, quantificação da produção diária de néctar, levantamento da entomofauna que visita as flores da amoreira na área de estudo e análise do seu comportamento polinizador. Os experimentos foram realizados em uma área de cultivo de amoreira-preta, no mês de dezembro de 2005, município de Timbó (SC. Constatou-se que a maior taxa de frutificação (48,3 % ± 3,2 ocorreu via polinização livre, onde os insetos não foram excluídos. Foi verificada a ocorrência de autopolinização, porém com taxa inferior de frutificação (12,2% ± 4,9. A anemofilia não foi constatada na espécie. A avaliação da produção de néctar em Rubus sp. resultou em valores compatíveis com a síndrome de melitofilia. Os visitantes florais coletados e observados sobre as flores de Rubus sp. foram predominantemente abelhas da ordem Hymenoptera (97%, que iniciam, em menor número, a atividade de forrageamento às 8h, com pico de atividade às 12h e declinando até às 16h. As coletas resultaram numa amostragem de 1.360 abelhas, divididas em quatro famílias e 13 espécies. A família com maior riqueza de espécies (N = 7 foi Halictidae e a mais abundante foi Apidae, com 1.288 indivíduos. Em Apidae, houve o predomínio da espécie exótica Apis mellifera, cuja representação na amostra foi de 1.246 indivíduos. Os dados da abundância e as observações naturalísticas do seu comportamento da flor apontaram A. mellifera como o principal polinizador de Rubus sp., mas confirmam que as demais espécies de abelhas também participam na polinização de Rubus sp.

    Full Text Available Foram estudadas a composição bromatológica e a conservação de subprodutos da cana-de-açúcar tratados com 0, 1, 2 e 4% (N-amônia na matéria seca nas formas de amônia anidra, uréia e sulfato de amônio, em arranjo fatorial e delineamento inteiramente casualizado. Não houve alteração no teor de matéria seca do bagaço, em função das fontes de amônia. As fontes de amônia promoveram decréscimo no teor de fibra em detergente neutro do bagaço, entretanto, só com o sulfato de amônia a ponta apresentou tal comportamento. Houve redução no teor de hemicelulose dos subprodutos tratados com uréia, em função dos níveis de amônia. A amonização com sulfato de amônio reduziu o teor de fibra em detergente ácido, principalmente, da ponta. Houve decréscimo no teor de celulose do bagaço tratado com amônia anidra. Os tratamentos resultaram em aumento no teor de proteína bruta de ambos subprodutos, em função dos níveis de amonia. O sulfato de amônio promoveu redução no teor de nitrogênio insolúvel em detergente ácido e maior retenção de nitrogênio nos dois subprodutos. Na maioria dos tratamentos, os períodos após abertura dos silos não alteraram o teor de nitrogênio total dos subprodutos. Os benefícios promovidos pelos tratamentos persistiram até o 48º dia para o bagaço e até o 24º dia para a ponta.

    Numerical modelling of marine ecology exploits several assumptions and it is indeed quite challenging to include marine ecological phenomena into a mathematical framework with too many unknown parameters. The governing ordinary differential equations represent the interaction of the biological and chemical processes in a marine environment. The key concern in the development of a numerical models are parameterizations based on output, viz., mathematical modelling of ecological system mainly depends on parameters and its variations. Almost, all constituents of each trophic level of marine food web are depended on phytoplankton, which are mostly influenced by initial slope of P-I curve and nutrient stock in the study domain. Whereas, the earlier plankton dynamic models rarely include a compartment of small fish and as an agent in zooplankton mortality, which is most important for the modelling of higher trophic level of marine species. A compartment of forage fish in the modelling of plankton dynamics has been given more realistic mortality rates of plankton, viz., they feed upon phytoplankton and zooplankton. The inclusion of an additional compartment increases complexity of earlier plankton dynamics model as it introduces additional unknown parameters, which has been specified for performing the numerical simulations.As a case study we applied our analysis to explain the aquatic ecology of Gulf of Khambhat (19o 48' N - 22o20' N, 65o E - 72o40' E), west coast of India, which has rich bio-diversity and a high productive area in the form of plankton and forage fish. It has elevated turbidity and varying geography location, viz., one of the regions among world's ocean with high biological productivity.The model presented in this study is able to bring out the essential features of the observed data; that includes the bimodal oscillations in the observed data, monthly mean chlorophyll-a in the SeaWiFs/MODIS Aqua data and in-situ data of plankton.

    Full Text Available Background In recent years, bioactive bioceramics such as bioglass and hydroxyapatite (HA have been introduced as a remarkable development in the field of medicine due to their bio-adaptability, non-toxicity, and persistence, in vivo. They have many potential applications in the repair of bone defects and hence they have attracted significant interest from scholars. Objectives The aim of this study was to synthesize inorganic matrix CuO-based bioglasses and evaluate their antibacterial activity against aerobic bacterial infections in bone implants. Methods Nano-composite samples of silica-based bioactive glass, 60S BG with nano-powder CuO, were synthesized using the sol-gel method and then assessed with regard to their antibacterial properties against Staphylococcus aureus using well diffusion agar. The samples included BG58S (58%SiO2, 36%CaO, 6%P2O5, BG/10CuO (58%SiO2, 26%CaO, 6%P2O5, 10%CuO, and BG/20CuO (48%SiO2, 26%CaO, 6%P2O5, 20%CuO. To evaluate their bioactivity, the prepared samples of BG/20CuO, BG/10CuO, and BG58S were immersed in simulated body fluids (SBF. The surface morphology and structure of the samples before and after immersion in the SBF were characterized using scanning electron microscopy (SEM and Fourier transform infrared (FTIR, respectively. Then, the BG/20CuO and BG/10CuO samples were loaded in clindamycin, an antibiotic widely used in the treatment of osteomyelitis, and their release profiles were studied in phosphate buffer solution. Results It was observed that the growth inhibition zone increased through clindamycin release due to the increasing CuO percentage in the nanocomposite of bioactive glass. The bioactivity of the nanocomposite/bioglass with CuO was superior to that of bioglass alone. In this study, the BG/20CuO sample showed a sustained release of clindamycin, which is sufficient for a drug delivery system. Conclusions Increasing the Cu nanoparticles in bioactive glass samples leads to the release of Cu2

    Severe Acute Liver Failure (ALF) is a life-threatening clinical syndrome characterized by hepatocyte necrosis, loss of hepatic architecture, and impairment of liver functions. One of the main causes of ALF is hepatotoxicity from chemical agents, which damage hepatocytes and result in increase of reactive oxygen species. The vitamin E isoform is the one with the strongest biological antioxidant activity. To evaluate the antioxidant effect of vitamin E in this ALF model. We used 56 rats (mean weight of 300 g) divided into eight groups, four groups assessed at 24 hours and 4 assessed at 48 hours after induction: control group (CO); Vitamin E (Vit. E); Thioacetamide (TAA) and Thioacetamide + Vitamina E (TAA+Vit.E). Rats were submitted to injections of thioacetamide (400 mg/kg i.p.) at baseline and 8 hours later. Vitamin E (100 mg/kg ip) was administered 30 minutes after the second dose of thioacetamide. The 48-hour group rats received two additional doses of vitamin E (24h and 36h). At 24h or 48 hours after the administration of the first dose of TAA, rats were weighed and anesthetized and their blood sampled for evaluation of liver integrity through enzymes aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Liver tissue was sampled for assessment of lipid peroxidation (LPO) by the technique TBARS, antioxidant enzymes SOD, CAT, GPx and GST activity, levels of the NO 2 /NO 3 and histology by H&E in two times. The results were expressed as mean ± standard deviation and statistically analyzed by ANOVA followed by Student-Newman-Keuls, with P E, we observed a reduction in liver enzymes AST (U/L) (101.32±19.45 in 24 hours and 97.85±29.65 in 48 hours) related to the TAA group (469.56± 0.69 in 24 hours and 598.23±55.45 in 48 hours) and ALT (U/L) (76.59±8.56 in 24 hours and 68.47±6.49 in 48 hours) compared to the TAA group (312.21±10.23 in 24 hours and 359.15±17.58 in 48 hours).

    Autopsy findings in patients with bladder carcinoma, treated by combined operation and radiotherapy, revealed tendencies of tumor spread as well as complications and late effects of radiotherapy. In 24.5% of the cases tumor tissue was found within the bladder and in 30.5% within the minor pelvis. Metastases were found in 24.1% in iliac lymph nodes, in 21.3% in abdominal lymph nodes. Liver, lungs, bones, and kidneys are main organs for hematological metastasizing. Little or undifferentiated carcinomas and squamous cell carcinomas showed a greater tendency to metastasize than highly and medium-differentiated ureteral carcinomas. The least radiotherapeutical complications and late effects were found in a fractionation with daily 1.5 Gy and a total dose of 60 Gy. (author)

    proposes to adiabatically relax the trapping potential, called adiabatic cooling, when performing rovibrational excitations of the molecular ion to reduce the energy spacing of the harmonic motional levels, thus increasing the likelihood of a motional transition. The work presented in this thesis covers...... the implementation of adiabatic cooling for the application of rovibrational spectroscopy on single molecular ions. This entailed constructing and testing a new DC supply capable of employing adiabatic ramps of the ion's axial frequency on the 100's of us timescale. The DC supply went through several iterations...... is possible with some optimization. Rovibrational transitions in 24MgH+ are only known to the 1.5 GHz level compared to their Hz-linewidths. Simulations for broadband spectroscopy aimed reducing this uncertainty are presented for a rovibrational transition in 24MgH+. This technique allows for illumination...

    This paper describes 50 consecutive patients who sonographically had gallbladder stones and dilated bile ducts, but no visible aetiology for the dilatation. We reviewed these cases to determine the frequency of choledocholithiasis in this setting. Common duct stones caused obstruction in only 36% of these patients. Other aetiologies included strictures due to chronic pancreatitis or prior stone passage in 24% of the patients, and malignant obstruction in 16%. In 24% of the patients, no cause was found for biliary dilatation: common duct stones or obstructing tumours were excluded in the group. Since aetiologies other than stones are likely in a majority of cases, further preoperative workup (CT, percutaneous transhepatic cholangiography, ERCP) or intraoperative cholangiography (if the patient requires urgent cholecystectomy) is indicated. The additional studies should provide a diagnosis, help determine whether or not the common duct should be explored, or avoid unnecessary operation in case of incurable malignancy.

    The results of urinary determinations of E-2 prostaglandines by radioimmunoassay (RIA) in 24-hour urine are presented for three groups: progressive systemic sclerotic patients with normotension and with elevated or normal APR, progressive systemic sclerotic patients with hypertension and with normal or low APR, control group of normal subjects. In a recent report of progressive systemic sclerosis in patients we demonstrated changes in the urine concentratrion of APR levels, sodium excretion and in total blood volume. Based on these findings we felt the need to perform quantifications of E-2 prostaglandines (PGE-2) in 24-hour recently taken urine samples stored at 70 0 and measure the sodium amounts excreted in the urine. We concluded that urinary determination of E-2 prostaglandines was the most suitable for our study as it allowed the establishment of relationships between APR, aldosterone and metabolic sodium balance.

    Three subjects are discussed in this paper. 1) The mechanism of (HI, α) reactions is briefly studied. 2) Possible excitation of molecular resonance states of 12 C- 12 C in 24 Mg through the 12 C( 16 O, α) 24 Mg reaction were investigated. A precise measurement of the level widths in 24 Mg did not support the previous report that the molecular states seen in 12 C + 12 C scattering had been excited in the transfer reaction 12 C( 16 O, α) 24 Mg. 3) Highly excited states in 28 Si, which have a large parentage of 12 C- 16 O, were also studied via the 12 C( 20 Ne, α) 28 Si reaction. An angular correlation measurement revealed the lowest 8 + and 10 + states at 14.00 and 15.97 MeV, respectively, which were selectively excited in the 12 C( 20 Ne, α) reaction. These results suggest a possible new band in 28 Si. (author)

  14. Immunohistochemical Localization of GFAP and Glutamate Regulatory Proteins in Chick Retina and Their Levels of Expressions in Altered Photoperiods.

    Jha, Kumar Abhiram; Nag, Tapas C; Wadhwa, Shashi; Roy, Tara Sankar

    2017-08-01

    Moderate to intense light is reported to damage the chick retina, which is cone dominated. Light damage alters neurotransmitter pools, such as those of glutamate. Glutamate level in the retina is regulated by glutamate-aspartate transporter (GLAST) and glutamine synthetase (GS). We examined immunolocalization patterns and the expression levels of both markers and of glial fibrillary acidic protein (GFAP, a marker of neuronal stress) in chick retina exposed to 2000 lux under 12-h light:12-h dark (12L:12D; normal photoperiod), 18L:6D (prolonged photoperiod), and 24L:0D (constant light) at post-hatch day 30. Retinal damage (increased death of photoreceptors and inner retinal neurons and Müller cell hypertrophy) and GFAP expression in Müller cells were maximal in 24L:0D condition compared to that seen in 12L:12D and 18L:6D conditions. GS was present in Müller cells and GLAST expressed in Müller cell processes and photoreceptor inner segments. GLAST expression was decreased in 24L:0D condition, and the expression levels between 12L:12D and 18L:6D, though increased marginally, were statistically insignificant. Similar was the case with GS expression that significantly decreased in 24L:0D condition. Our previous study with chicks exposed to 2000 lux reported increased retinal glutamate level in 24L:0D condition. The present results indicate that constant light induces decreased expressions of GLAST and GS, a condition that might aggravate glutamate-mediated neurotoxicity and delay neuroprotection in a cone-dominated retina.

A negative correlation between serum oestrogen and mean duration of analgesia further support this, indicating that low serum oestrogen level decreases pain sensitiv-ity and high serum oestrogen level increases pain sensitivity.

    Scintiscanning of the cervical cerebrospinal fluid space at maximum ante- and retroflexion in 24 patients revealed the method to be recommended for use in the case of cervical myelopathy when the polymorphous early symptoms appear and before myelography as well as for follow-up examination. The detection of posture-induced constriction of the lumen provides additional information and increases the sensitivity considerably because, particularly during retroflexion, minor inflammatory reactions lead to scintigraphically detectable reduction in the liquor space.

    HDL particles are protein-rich particles that act as a vehicle for reverse cholesterol transport from tissues to the liver. The purpose of this study was to investigate age-dependent changes in the functional activity of HDL and the effect of high-energy diet on this index, as well as to correct it under the influence of grape polyphenols from “Enoant” obtained from Vitis vinifera grapes. We observed the age-dependent composition changes in HDL particle. It was shown that total lipids and triacylglycerol (TG) levels were higher in 24-month-old animals. In obese rats, HDL total lipids and TG levels were higher in 24-month-old than in the 3-month-old and 12-month-old groups but did not differ from 24-month-old group. The plasma HDL paraoxonase (PON) and lecithin:cholesterol acyltransferase (LCAT) activity levels were decreased in old-aged rats, and cholesteryl ester transfer protein (CETP) activity was higher in old rats. Keeping 12-month-old animals on high-fructose diet completely leveled the age differences in the data that have been measured between 12-month-old and 24-month-old rats. After “Enoant” administration, an increase of HDL PON and LCAT activity levels and a reduction of CETP activity were found in 24-month-old and obese rats. PMID:23936611

    Full Text Available Background: Knowledge of the wide spectrum of the oral markers of diabetes is imperative as one frequently encounters individuals with undetected, untreated or poorly controlled diabetes. Objectives: The objective was to study the oral manifestations in type 2 diabetes mellitus (DM and to establish an association between oral manifestations and associated microvascular and macrovascular complications. Materials and Methods: 50 cases of DM were selected who had oral complications. The control group comprised 50 age- and sex-matched diabetic patients without any oral complications. Results: Oral manifestations in DM included periodontal disease in 34%, oral candidiasis in 24%, tooth loss in 24%, oral mucosal ulcers in 22%, taste impairment in 20%, xerostomia and salivary gland hypofunction in 14%, dental caries in 24%, and burning mouth sensation in 10% cases. Fasting [(FBG (P = 0.003] and postprandial blood glucose [(PPBG (P = 0.0003] levels were significantly higher among cases. The P values for neuropathy, retinopathy, nephropathy, cardiovascular disease, dyslipidemia, and sepsis were 0.0156, 0.0241, 0.68, 0.4047, 0.0278, and 0.3149, respectively, which were significant for neuropathy, retinopathy, and dyslipidemia. Conclusions: Several oral complications are seen among diabetics. Association of oral markers in DM and microvascular complications suggests that there is a significant association between the two.

A partir do 9º dia e até o 48º dia de alimentação, os órgãos (intestino médio, fígado e pâncreas de três girinos de cada grupo foram fixados em solução histológica de Bouin para coloração por hematoxilina e eosina. A presença de tecido conjuntivo extremamente frouxo nas alças intestinais dos girinos sugeriu situação provisória para a mudança da arquitetura intestinal após a metamorfose. Nesse período, observou-se aumento no número de células caliciformes e de microvilosidades e, no 25º dia, verificou-se a presença de células hepáticas, com arranjo glandular mais compacto, o que sugere funcionalidade e confirma os melhores resultados de desempenho obtidos a partir desse período nos girinos alimentados com as rações com maior nível protéico. No 35º dia, observou-se a estrutura do fígado bilobado, com sinais de desorganização, o que indica rarefação celular protéica, decorrente de mau aproveitamento da proteína da ração.

    Full Text Available Introducción: Cualquier practicante de ciencia está frecuentemente expuesto al discurso público (DP: conferencias, congresos, simposios, seminarios, entrevistas, talleres, etc. Por ello, es imprescindible saber comunicar las ideas con claridad y contundencia en una presentación oral. Usualmente, profesionistas y estudiantes enfrentan estas situaciones utilizando el sentido común, asumiendo que las habilidades para dar una buena presentación oral se adquieren con la práctica. Sin embargo es común ver profesionistas que a pesar de tener años de experiencia en foros de DP, siguen haciendo presentaciones orales muy deficientes. La hipótesis de este trabajo es que la práctica, por sí misma, puede no ser la única forma de adquirir dichas habilidades, sino que es posible mejorar el desempeño en las presentaciones orales mediante la enseñanza de las bases científicas del DP. Método: Tras una presentación oral individual de 10 minutos, se aplicó una prueba de desempeño en el DP (prueba Rapee a un grupo de 15 alumnos de posgrado en ciencias marinas antes y después de tomar un curso de DP. En el curso se enseñó la ciencia que existe detrás del DP, los protocolos del DP en la ciencia y la aplicación de los principios del diseño gráfico en el material de apoyo visual de una presentación oral. Los resultados generales de la prueba Rapee aplicada antes y después del curso se compararon mediante un análisis de diferencias de medias de muestras independientes (p valor de 0.05 y los resultados particulares mediante diagramas de contornos que representan la distribución de las calificaciones en función de las evaluaciones. Resultados: la calificación promedio del grupo en la prueba Rapee antes de que los alumnos tomaran el curso, se situó en un nivel de bajo desempeño (48 puntos de 68. Después de haber cursado la materia, este promedio se incrementó significativamente (de 48 a 57 puntos. La mejoría fue más evidente en las

    Background: Household cleaning products are associated with adverse respiratory health outcomes, but the cardiovascular health effects are largely unknown. Objective: We determined if long-term use of household sprays and scented products at home was associated with reduced heart rate variability (HRV), a marker of autonomic cardiac dysfunction. Methods: We recorded 24-hr electrocardiograms in a cross-sectional survey of 581 Swiss adults, ≥ 50 years of age, who answered a detailed questionnaire regarding their use of household cleaning products in their homes. The adjusted average percent changes in standard deviation of all normal-to-normal intervals in 24 hr (24-hr SDNN) and total power (TP) were estimated in multiple linear regression in association with frequency [air freshening sprays, and scented products. Results: Decreases in 24-hr SDNN and TP were observed with frequent use of all product types, but the strongest reductions were associated with air freshening sprays. Compared with unexposed participants, we found that using air freshening sprays 4–7 days/week was associated with 11% [95% confidence interval (CI): –20%, –2%] and 29% (95% CI: –46%, –8%) decreases in 24-hr SDNN and TP, respectively. Inverse associations of 24-SDNN and TP with increased use of cleaning sprays, air freshening sprays, and scented products were observed mainly in participants with obstructive lung disease (p < 0.05 for interactions). Conclusions: In predominantly older adult women, long-term frequent use of household spray and scented products was associated with reduced HRV, which suggests an increased risk of cardiovascular health hazards. People with preexisting pulmonary conditions may be more susceptible. PMID:22538298

    Mometasone furoate nasal spray (MFNS) improves nasal symptoms and reduces polyp size in adults with nasal polyposis. This 4-month, multinational, randomized, double-blind study was conducted to assess the safety of MFNS in pediatric subjects aged 6-17 yr. Subjects aged 6-11 yr with bilateral nasal polyps received MFNS 100 μg once or twice daily or placebo; those aged 12-17 yr received MFNS 200 μg once or twice daily or placebo. End-points included change in 24-h urinary free cortisol (primary), change in 24-h urinary free cortisol corrected for creatinine (key secondary), and adverse events. Efficacy parameters included polyp size, nasal symptoms, and investigator-evaluated therapeutic response, although the study was not powered for statistical analysis of efficacy. Least squares baseline mean urinary free cortisol level (nmol/24 h) for both age groups combined (N = 127) was 49.5 in the MFNS once-daily group, 39.6 in the MFNS twice-daily group, and 49.8 in the placebo group. Change in 24-h urinary free cortisol did not significantly differ among MFNS- and placebo-treated subjects. Least squares mean 24-h urinary free cortisol levels corrected for creatinine also showed no significant differences among MFNS- and placebo-treated subjects. No safety issues emerged. Results of this study confirm the safety profile of MFNS in pediatric patients with bilateral nasal polyps over 4 months, even at double the recommended pediatric dosage for allergic rhinitis. © 2012 John Wiley & Sons A/S.

    Full Text Available OBJECTIVES/PURPOSE To compare two dosing regimens of the same 25 mcg misoprostol with respect to Induction delivery interval, successful vaginal delivery and its associated maternal and neonatal outcomes. METHODS Prospective study was conducted among 300 low risk pregnant patients at 40 weeks’ gestation, attending labour room in the Dept. of OBG, Amala Institute of Medical sciences, comparing, A-single dose 25 mcg misoprostol in 24 hours Vs. B-multiple dose 25 mcg misoprostol (4 hourly up to 3 doses intravaginally for its effectiveness. RESULTS Statistically significant difference was obtained in the number of deliveries within 24 hours in group A and B (36.6% Vs. 63.4% with p value 0.002. The induction delivery interval between primigravidae and multigravidae were statistically significant (12.5 =/-3.9 Vs 11.08=/-4.3 with p value 0.035 but not significant between groups A and B. There was no statistical difference in other maternal and neonatal outcomes. Incidence of MSL and foetal distress were higher in primigravidae after single dose itself. Serious adverse outcomes like MAS, NND, APGAR<7 at one minute and uterine rupture were not encountered in this study. CONCLUSION Around 65% of women delivered with a single dose of misoprostol in 24 hours. Most multigravidae delivered vaginally with a single dose in 24 hours. It appears that in multigravidae a single dose induction is adequate; however, in primigravidae multiple doses of 25 mcg misoprostol is best to achieve delivery within 24 hours.

Presenting signs included retinal detachment in 24 children (100%, vascular telangiectasia in 24 children (100%, and retinal ischemia in 24 children (100%. Twenty of 24 children presented with elevated, vascular leakage in the fovea (83%. Two children presented with sub-retinal fibrosis associated with presumed long-standing retinal detachment without evidence of rhegmatogenous retinal detachment. Ten patients exhibited vascular alterations in the periphery of the second eye without clinical evidence of exudation. All 24 children were treated with a large-spot-size diode laser directly to areas of abnormal telangiectatic vasculature. All 24 children received intravitreal bevacizumab injection. Results: All 24 children had resolution of exudative retinal detachment, ablation of vascular telangiectasia, and anatomic improvement of the retina. No child exhibited progressive retinal detachment and no eye required enucleation. No cases of neovascular glaucoma were seen. Fellow eyes with peripheral vascular alterations showed no progression to exudative vasculopathy during the observation period. Intravitreal bevacizumab injection was not associated with endophthalmitis or systemically-observed complications.Conclusion: Repetitive intravitreal bevacizumab combined with laser vascular ablation may be utilized effectively

    Background: Limited knowledge regarding the reproducibility of biomarkers in 24-h urine samples has hindered the collection and use of the samples in epidemiologic studies. Objective: We aimed to evaluate the reproducibility of various markers in repeat 24-h urine samples. Design: We calculated intraclass correlation coefficients (ICCs) of biomarkers measured in 24-h urine samples that were collected in 3168 participants in the NHS (Nurses’ Health Study), NHSII (Nurses’ Health Study II), and Health Professionals Follow-Up Study. Results: In 742 women with 4 samples each collected over the course of 1 y, ICCs for sodium were 0.32 in the NHS and 0.34 in the NHSII. In 2439 men and women with 2 samples each collected over 1 wk to ≥1 mo, the ICCs ranged from 0.33 to 0.68 for sodium at various intervals between collections. The urinary excretion of potassium, calcium, magnesium, phosphate, sulfate, and other urinary markers showed generally higher reproducibility (ICCs >0.4). In 47 women with two 24-h urine samples, ICCs ranged from 0.15 (catechin) to 0.75 (enterolactone) for polyphenol metabolites. For phthalates, ICCs were generally ≤0.26 except for monobenzyl phthalate (ICC: 0.55), whereas the ICC was 0.39 for bisphenol A (BPA). We further estimated that, for the large majority of the biomarkers, the mean of three 24-h urine samples could provide a correlation of ≥0.8 with true long-term urinary excretion. Conclusions: These data suggest that the urinary excretion of various biomarkers, such as minerals, electrolytes, most polyphenols, and BPA, is reasonably reproducible in 24-h urine samples that are collected within a few days or ≤1 y. Our findings show that three 24-h samples are sufficient for the measurement of long-term exposure status in epidemiologic studies. PMID:28049663

    The rate of calcium extraction with EDTA (ethylenediamine tetraacetic acid) from thin bone slices (300 micrometer-3 mm thick) was determined by aid of an atomic absorption spectrophotometer. A 0.5 mm thick bone slice was completely decalcified with 15% (0.40 M), 8% (0.22 M), and 4% (0.11 M) EDTA in 24 h, 3 days, and 5 days, respectively (vol. 15 ml, temp. 4 degrees C, pH 7.4). At 37 and 60 degrees C the speed of demineralization was slightly increased as compared with that at 20 degrees C, while no difference was observed between 4 and 20 degrees C. Bone slices with a thickness of 0.3, 0.5, 1 and 2 mm were decalcified -- in the same order -- in 24 h, 2, 3, and 5 days (8% EDTA, 4 degrees C, pH 7.4). At pH 7.4, the decalcification rate was a little slower than at pH 5.0 and 8.5. Agitation did not affect the decalcifying velocity, nor did the volume of the agent, except when the volume was very small. The demineralization of ordinary bone, containing both compact and spongy bone, was found to be more rapid than that of homogeneous bone reported earlier. The acidic buffers and New Decalc, which served as reference substances, exerted a more vigorous decalcifying effect thatn EDTA. K formate/formic acid buffer, pH 3.15, demineralized a 1 mm thick bone slice in 24 h and 2 days was needed with Na lactate/lactic acid buffer, pH 3.70. With New Decalc, pH 0.9, the corresponding demineralization was accomplished in 1.5 h. Atomic absorption spectrophotometer proved to be a useful tool in the evaluation of calcium extraction velocity from bone slices.

    Project Northland is designed to prevent alcohol use among young adolescents. The project is ongoing in 24 school districts, randomly assigned to intervention or reference conditions. Multiple interventions begin with sixth graders and continue through eighth grade. The reference districts offer their standard health curricula. Evaluation consists of school surveys with the cohort (N = 2201) and telephone surveys of half their parents. This article describes the sixth-grade home-based intervention, the Slick Tracy Home Team. Findings of broad-based participation across sex, race, and risk status were documented, as well as some increases in knowledge and family communication about alcohol use.

    Empagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor, ameliorates hyperglycemia in patients with type 2 diabetes (T2D) by inducing sustained glucosuria. Empagliflozin treatment was previously associated with a transient increase in 24-h urine volume in Caucasian patients with T2D, however comparable evidence in Japanese T2D individuals is scarce. We therefore assessed acute and chronic changes in 24-h urine volume and fluid intake with empagliflozin in Japanese patients with T2D. In this randomized, double-blind, placebo-controlled, parallel-group, multiple-dose, 4-week trial, 100 Japanese patients with T2D were randomized to receive either 1, 5, 10, or 25 mg empagliflozin or placebo once-daily. Changes from baseline in 24-h urine volume and fluid intake were assessed at days 1, 27, and 28 after the initiation of empagliflozin. The 24-h urine volume and fluid intake were comparable across all treatment groups at baseline. Patients treated with either 10 or 25 mg empagliflozin (i.e., the licensed doses in Japan) showed a significant increase in 24-h urine volume compared to placebo at day 1 (mean change from baseline: + 0.83, + 1.08, and + 0.29 L/day in the empagliflozin 10 and 25 mg groups and the placebo group, respectively; both p empagliflozin groups were comparable to placebo at day 27 and 28 (differences vs placebo  0.05). The 24-h fluid intake was comparable across all study groups throughout the entire study period. No events consistent with dehydration were reported during empagliflozin treatment. Treatment initiation with empagliflozin in Japanese patients with T2D was associated with transient diuresis; however, overall urine volume returned towards baseline levels within 4 weeks of treatment. These findings are consistent with a physiological, adaptive mechanism of the kidney to maintain overall body fluid balance in response to treatment initiation with a SGLT2 inhibitor. NCT00885118.

    To investigate the effect of different pH on rectum permeability of chlorogenic acid and geniposide. Four kinds of Reduning suppositories of different pH were separated and put into the rectum to study the suppositories in vitro and the content of chlorogenic acid and geniposide samples was determined by HPLC to calculate the permeation in 24 hours. With increase of pH within 2.5-7.4, the steady state flux of chlorogenic acid was increased, but the steady state flux of geniposidesamples was steady. Adjusted the pH can increase the rectum permeability of active ingredients in Reduning auppositories.

    2016-03-01

    This study investigated whether itch induced by intra-epidermal histamine is subjected to modulation by a standardized conditioned pain modulation (CPM) paradigm in 24 healthy volunteers. CPM was induced by computer-controlled cuff pressure algometry and histamine was introduced to the volar forearm by skin prick test punctures. Moreover, neurogenic inflammation and wheal reactions induced by histamine and autonomic nervous system responses (heart rate variability and skin conductance) were monitored. CPM did not modulate the intensity of histamine-induced itch suggesting that pruriceptive signaling is not inhibited by pain-recruited endogenous modulation, however, CPM was found to aggravate histamine-induced neurogenic inflammation, likely facilitated by efferent sympathetic fibers.

    Full Text Available Background: Hydroxyapatite nanoparticles have a more surface contact and solubility than conventional hydroxyapatite. Hydroxynanoparticles enhances the biological and mechanical properties of new regenerated tissues. The hydroxyapatite nanoparticles have received attention as a new and effective osseous graft for using as scaffolds in bone regeneration. The reports on hydroxyapatite nanoparticles biocompatibility are controversial. It has been shown that hydroxyapatite nanoparticles induces inflammatory reaction and apoptosis. The aim of the present study was to evaluate the cytotoxicity of nano-hydroxyapatite on the human epithelial cells. Methods: The study was experimental and completed in vitro. The study was carried out in department of Immonulogy, Faculty of Medicine, Shahid Beheshti University of Medical Sciences in November 2014. The human-derived oral epithelium cell line (KB obtained from Pasteur Institute, Tehran, Iran were exposed to hydroxyapatite nanoparticles at 0.01, 0.05, 0.1, 0.5, 0.75, 1, 2.5 and 5 mg/ml concentrations in 24, 48 and 72 hours. Rod-shaped hydroxyapatite nanoparticles with 99% purity and maximum 100 nm sized particles were used. Methylthiazol tetrazolium bromide (MTT method was employed for cell vitality evaluation. Enzyme-linked immunosorbent assay (ELISA was used for assessing the viability of cells. Distilled water and fetal bovine serum (FBS were positive and negative controls. ANOVA and Duncan tests were used for statistical analysis. Results: The cytotoxicity of different concentrations of hydroxyapatite nanoparticles on human-derived oral epithelium cell line in 24 (P< 0.001, 48 (P< 0.001 and 72 hours (P< 0.001 was significantly different. The nano-hydroxyapatite particles at 0.5 to 1 mg/ml had the highest cytotoxicity effect on human-derived oral epithelium cells in 24, 48 and 72 hours. Lower concentrations than 0.05 mg/ml had the best biocompatibility properties in 24, 48 and 72 hours. Conclusion

    Summer camps for adolescent cancer patients and survivors are popular. Little is known about the impact of camp attendance on physical activity (PA) and fatigue. This pilot study was conducted in 24 adolescents, 13-17 years of age, to measure objective PA (steps/day) along with self-reported PA and fatigue during camp. Findings demonstrate adolescents are willing to complete a PA research study during camp. On average, campers demonstrated 18,198 steps/day. Self-reported PA significantly increased with no significant change in self-reported fatigue. Summer camps offer a unique setting, in which to encourage and explore PA in adolescent oncology patients and survivors.

    This letter presents new data on the multiplicity distribution of charged secondaries in 24 Mg interactions with AgBr at 4.5 GeV/c per nucleon. The validity of the negative binomial distribution (NBD) is studied. It is observed that the data can be well parametrized in terms of the NBD law for the whole phase space and also for different pseudo-rapidity bins. A comparison of different parameters with those in the case of h-h interactions reveals some interesting results, the implications of which are discussed. (orig.)

    The records of all patients undergoing hepatobiliary imaging with technetion radioisotopes at our hospital from January 1980 to March 1983 were reviewed and 29 scans met the criteria for a pattern consistent with complete biliary tract obstruction. Biliary tract obstruction (due to choledocholithiasis, primary or secondary carcinoma involving the common bile duct, and pancreatitis) was documented in 24 of these patients. However, the remaining five patients had a patent common bile duct, and the etiologic factor was intrahepatic cholestasis secondary to sepsis in four and peritonitis in one. A classification of altered biliary dynamics in hepatobiliary imaging, which is based on the classification of jaundice, is proposed.

    Full Text Available In this paper, we present a review of different recommender system algorithms that are utilized in social networks based e-Learning systems. Future research will include our proposed our e-Learning system that utilizes Recommender System and Social Network. Since the world is full of indeterminacy, the neutrosophics found their place into contemporary research. The fundamental concepts of neutrosophic set, introduced by Smarandache in [21, 22, 23] and Salama et al. in [24-66].The purpose of this paper is to utilize a neutrosophic set to analyze social networks data conducted through learning activities.

    Suboptimal asthma control may be caused by a combination of factors, such as nonadherence to guidelines, lack of compliance, and poor asthma education. The aim was to assess patients' knowledge of asthma and different management strategies, including patients' attitudes toward involvement...... of uncontrolled disease with night asthma (16%), daily symptoms (18%), or exercise-induced asthma (11%) were found. Of 285 participants with persistent asthma, 70% used inhaled corticosteroids. Lung function was measured within the preceding 6 months in 24% of patients, whereas 7% had never had their lung...

    All 470 scans on 132 consecutive renal transplantation patients were reviewed. Scan patterns identified included acute tubular necrosis and conventional rejection. A new pattern, donor specific rejection (DSR), was identified in 24 of 42 patients on the living related donor specific transfusion (DST) protocol. This was characterized by good perfusion and extraction but significant renal stasis of tracer. This pattern was unique to the DST recipients and improved with antirejection therapy. The clinical features (incidence, temporal onset) and severity (duration, serum creatinines) are compared in these patient populations. DSR occurs more frequently than conventional rejection but is a milder process

    G is related with economic and social development, better environmental conditions, and better quality of life. Yet while governance indicators have proliferated in recent years, their focus remains almost universally on analysis at the country level. Moreover, the majority of indices rely on expert...... regions in 24 European countries. The ‘European Quality of Government Index’, which will be published free for scholarly use, is built on the largest survey to date focusing on governance at the regional level; over 85,000 citizens were surveyed. The instrument proposed here builds on both perceptions...

    We evaluated whether low-grade albuminuria or black race modulates ambulatory blood pressure (BP) or nocturnal BP response to the DASH diet. Among 202 adults enrolled in the DASH multicenter trial who were fed the DASH or control diet for 8 weeks, reductions in 24-hour daytime and nighttime SBP and DBP were significantly larger for DASH compared to control. Median changes in nocturnal BP dipping were not significant. Compared to urine albumin excretion of DASH on ambulatory BP in the presence of low-grade albuminuria. ©2018 Wiley Periodicals, Inc.

    With the view of designing a single biocatalyst for biorefining, carbazole dioxygenase was cloned from Pseudomonas sp. and expressed in Rhodococcus sp. The recombinant, IGTS8, degraded both carbazole and dibenzothiophene at 400 mg/l in 24 h. Maximum carbazole degradation was in 1:1 (v/v) hexadecane/aqueous phase. Anthracene, phenanthrene, pyrene, fluoranthene and fluorine were also degraded without affecting the aliphatic component. Recombinant Rhodococcus sp. IGTS8 can function as a single biocatalyst for removing major contaminants of fossil fuels viz. dibenzothiophene, carbazole and polyaromatic compounds.
