This study draws attention toward the intracellular cytotoxicity of DMSA as a coating molecule of nanoparticles, which has very low toxicity as an orally administered antidote due to its extracellular distribution.We report the tunable electrical response in functionally graded interfaces in lead-free ferroelectric thin films. Multilayer thin film graded heterostructures were synthesized on platinized silicon substrate with oxide layers of varying thickness. Interestingly, the graded heterostructure thin films exhibited shift of the hysteresis loops on electric field and polarization axes depending upon the direction of an applied bias. A diode-like characteristics was observed in current-voltage behavior under forward and reverse bias. This modulated electrical behavior was attributed to the perturbed dynamics of charge carriers under internal bias (self-bias) generated due to the increased skewness of the potential wells. The cyclic sweeping of voltage further demonstrated memristor-like current-voltage behavior in functionally graded heterostructure devices. The presence of an internal bias assisted the generation of photocurrent by facilitating the separation of photogenerated charges. These novel findings provide opportunity to design new circuit components for the next generation of microelectronic device architectures.
Prasugrel is a third-generation thienopyridine, with significant pharmacodynamic and clinical advantages over clopidogrel. There are few data on the effects of prasugrel therapy, as compared with clopidogrel, in terms of perfusion during percutaneous coronary intervention (PCI), in patients with ST-elevation myocardial infarction (STEMI).

A total of 128 patients with STEMI, pretreated with prasugrel 60 mg loading dose (mean age=55.9±9.1; 10.9% were women and 18.0% had diabetes), were compared with 128 propensity-matched patients pretreated with clopidogrel 600 mg (mean age=58.7±10.7; 10.2% were women and 19.5% had diabetes) for the primary endpoint of thrombolysis in myocardial infarction (TIMI) flow and myocardial blush grade at completion of the PCI. Secondary endpoints included the combined sum of major adverse events death, reinfarction or target vessel revascularization at 1 year.

Mean TIMI flow grade pre-PCI was similar between the two groups (1.31±1.3 in the prasugrel group and 1.30±1.2 in the clopidogrel group, P=0.96). However, after intervention, it was higher in the prasugrel group (2.94±0.24 vs. 2.84±0.37, respectively, P=0.016), as was myocardial blush (2.70±0.76 vs. 2.31±0.52, respectively, P<0.001). The percentage of TIMI 3 after intervention was also higher in the prasugrel group (97.70 vs. 90.60%, P=0.02). The combined rate of major adverse events at 1 year (8.7 vs. 11.6%, P=0.11), as well as total mortality (3.1±5.6 vs. 4.7±9.1%, P=0.52), did not differ between the two groups.

In patients with STEMI undergoing primary PCI, pretreatment with prasugrel resulted in better angiographic perfusion results, as compared with pretreatment with clopidogrel.

A theoretical and spectroscopic investigation' by Michael H. Abraham et al., Phys. E6446 clinical trial Chem. Chem. Phys., 2015, DOI 10.1039/c5cp04061b.The influence of microbubbles on sonochemical efficiencies has been investigated under 28, 45, and 100 kHz ultrasound irradiation. For the 28 and 100 kHz ultrasound frequencies, microbubbles suppressed the I3(-) formation from KI solution as well as the 7-hydroxycoumarin formation from coumarin solution caused by the ultrasonic irradiation. On the other hand, for the 45 kHz ultrasound frequency, microbubbles enhanced the I3(-) formation from KI solution as well as 7-hydroxycoumarin formation from coumarin solution caused by the ultrasonic irradiation. Detection of H2O2 after the irradiation of ultrasound in the presence or absence of microbubbles was also performed, and it was found that H2O2 formation was enhanced only when microbubbles were introduced under the 45 kHz ultrasonic irradiation, which was in good agreement with the results of KI oxidation dosimetry measurements and of coumarin fluorescent probe measurements. Based on these present results, plausible mechanisms that explain the dependence of the ultrasound frequency on the enhancement and suppression of free radical formation in the presence of MBs were proposed.
This study aimed to investigate the validity and reproducibility of a new treadmill protocol in healthy children and adolescents the Fitkids Treadmill Test (FTT).

Sixty-eight healthy children and adolescents (6-18 yr) were randomly divided into a validity group (14 boys and 20 girls; mean ± SD age, 12.9 ± 3.6 yr) that performed the FTT and Bruce protocol, both with respiratory gas analysis within 2 wk, and a reproducibility group (19 boys and 15 girls; mean ± SD age, 13.5 ± 3.5 yr) that performed the FTT twice within 2 wk. A subgroup of 21 participants within the reproducibility group performed both FTT with respiratory gas analysis. Time to exhaustion (TTE) was the main outcome of the FTT.

V˙O2peak measured during the FTT showed excellent correlation with V˙O2peak measured during the Bruce protocol (r = 0.90; P < 0.01). Backward multiple regression analysis provided the following prediction equations for V˙O2peak (L·min) for boys and girls, respectively V˙O2peak FTT = -0.748 + (0.117 × TTEFTT) + (0.032 × body mass) + 0.263, and V˙O2peak FTT = -0.748 + (0.117 × TTEFTT) + (0.032 × body mass) [R = 0.935; SEE = 0.256 L·min]. Cross-validation of the regression model showed an R value of 0.76. Reliability statistics for the FTT showed an intraclass correlation coefficient of 0.985 (95% confidence interval, 0.971-0.993; P < 0.001) for TTE. Bland-Altman analysis showed a mean bias of -0.07 min, with limits of agreement between +1.30 and -1.43 min.

Results suggest that the FTT is a useful treadmill protocol with good validity and reproducibility in healthy children and adolescents. Exercise performance on the FTT and body mass can be used to adequately predict V˙O2peak when respiratory gas analysis is not available.

The aim of this project was to develop a biomechanically based quantification of the Balance Error Scoring System (BESS) using data derived from the accelerometer and gyroscope of a mobile tablet device.

Thirty-two healthy young adults completed the BESS while an iPad was positioned at the sacrum. Data from the iPad were compared to position data gathered from a three-dimensional motion capture system. Peak-to-peak (P2P), normalized path length (NPL), and root mean squared (RMS) were calculated for each system and compared. Additionally, a 95% ellipsoid volume, iBESS volume, was calculated using center of mass (CoM) movements in the anteroposterior (AP), mediolateral (ML), and trunk rotation planes of movement to provide a comprehensive, 3D metric of postural stability.

Across all kinematic outcomes, data from the iPad were significantly correlated with the same outcomes derived from the motion capture system (rho range, 0.37-0.94; P < 0.05). The iBESS volume metric was able to detect a difference in and 4, which often suffer from floor effects, and condition 5, which can experience ceiling effects. The iBESS metric is ideally suited for clinical and in the field applications in which characterizing postural stability is of interest.
Grafted skin impairs heat dissipation, but it is unknown to what extent this affects body temperature during exercise in the heat.

We examined core body temperature responses during exercise in the heat in a group of individuals with a large range of grafts covering their body surface area (BSA; 0%-75%).

Forty-three individuals (19 females) were stratified into groups based on BSA grafted control (0% grafted, n = 9), 17%-40% (n = 19), and >40% (n = 15). Subjects exercised at a fixed rate of metabolic heat production (339 ± 70 W; 4.3 ± 0.8 W·kg) in an environmental chamber set at 40°C, 30% relative humidity for 90 min or until exhaustion (n = 8). Whole-body sweat rate and core temperatures were measured.

Whole-body sweat rates were similar between the groups (control 14.7 ± 3.4 mL·min, 17%-40% 12.6 ± 4.0 mL·min; and >40% 11.7 ± 4.4 mL·min; P > 0.05), but the increase in core temperature at the end of exercise in the >40% BSA grafted group (1.6°C ± 0.5°C) was greater than the 17%-40% (1.2°C ± 0.3°C) and control (0.9°C ± 0.2°C) groups (P < 0.05). Absolute BSA of nongrafted skin (expressed in square meters) was the strongest independent predictor of the core temperature increase (r = 0.41). When regrouping all subjects, individuals with the lowest BSA of nongrafted skin (<1.0 m) had greater increases in core temperature (1.6°C ± 0.5°C) than those with more than 1.5 m nongrafted skin (1.0°C ± 0.3°C; P < 0.05).

These data imply that individuals with grafted skin have greater increases in core temperature when exercising in the heat and that the magnitude of this increase is best explained by the amount of nongrafted skin available for heat dissipation.

We investigated the effects of 24 wk of combined training on proinflammatory and anti-inflammatory markers associated with obesity in obese middle-age men.

Thirty obese men (48.73 ± 1.04 yr; body mass index, 31.00 ± 0.29 kg·m) underwent 24 wk of combined training [CT (N = 17), aerobic (50%-85% of V˙O2peak) and resistance (6-10 maximum repetition [RM]) training)] three times per week, 60 min per session, or a control group (N = 13). Anthropometric measures, maximal strength for leg press and bench press, peak oxygen uptake (V˙O2peak) and serum concentrations of C-reactive protein (CRP), tumor necrosis factor α (TNF-α), interleukin-6 (IL-6), IL-10, IL-15, resistin, leptin, and adiponectin were determined before (M1) and after 8 (M2), 16 (M3), and 24 (M4) wk of the experimental design.

Significant increases were observed in the maximal strength for bench press and leg press, V˙O2peak, and serum concentrations of adiponectin and IL-15 for CT. Concomitantly, significant decreases were observed in percentage body fat and serum concentrations of CRP, resistin, and leptin for CT after the experimental period.

Twenty-four weeks of moderate- to high-intensity CT reduced markers of subclinical inflammation associated with obesity and improved insulin resistance and functional capabilities of obese middle-age men, regardless of dietary intervention and weight loss.
