Factors Regulating Nitric Oxide Production in Spontaneously Hypertensive Rats Treated with Piper Sarmentosum Aqueous Extract

Introduction: Hypertension is a major risk factor for cardiovascular diseases which is one of the leading causes of death worldwide. Piper sarmentosum (PS) has been widely used in traditional medicine with proven antihypertensive and antioxidant effects. This study aims to evaluate the antihypertensive potential of PS aqueous extract (PSAE) and to investigate the factors modulating nitric oxide (NO) production through its anti-oxidant activities. Methods: PS leaves were extracted with distilled water, freeze-dried and examined to quantify their antioxidant activities through 2,2-diphenyl-1-picrylhydrazyl and ferric reducing ability plasma test. The antihypertensive effect of PSAE in spontaneous hypertensive rats (SHR) was evaluated using four different groups (n=6); C (negative control), K (PSAE 500mg/kg), P (3 mg/kg perindopril) and M (PSAE 500 mg/kg + 1.5 mg/kg perindopril). PSAE and other treatments were given via oral gavage for 28 days. The blood pressure (BP) was determined using the non-invasive BP monitoring tail cuff technique and recorded weekly. SHR’s blood was collected to determine the serum NO level using Griess assay. Asymmetric dimethylarginine (ADMA) and arginine levels were determined using high performance liquid chromatography. Results: The extract showed good in-vitro antioxidant activities and a significant reduction in both systolic and diastolic BP compared to control group. They were also a decrease in plasma ADMA and an increase in serum NO level. Meanwhile, arginine level does not change significantly. Conclusion: High in-vitro antioxidant activities in PSAE enhances the clearance of ADMA that leads to an increase in serum NO production hence ameliorating the blood pressure of SHR.
Parenting in an Era of Proactive Policing

Research increasingly documents the adverse consequences of police contact among adolescents, with police contact facilitating physical and mental health impairments, legal cynicism, and delinquency. The life course perspective suggests the repercussions of adolescent police contact likely extend beyond the adolescent to the broader family unit, but little research investigates this proliferation. The author used data from the Fragile Families and Child Wellbeing Study, a longitudinal survey of children who became adolescents during an era of proactive policing, to examine the relationship between adolescent police contact and four aspects of family life: mothersâ€™ parenting stress, mothersâ€™ monitoring, mothersâ€™ discipline, and the mother-adolescent relationship. Adolescent police contact, especially invasive police contact, is associated with increased parenting stress, increased discipline, and decreased engagement, net of adolescent and family characteristics that increase the risk of police contact. There is also suggestive evidence that adolescent police contact is more consequential when mothers themselves experienced recent police contact. Taken together, these findings suggest the repercussions of police contact extend beyond the individual and proliferate to restructure aspects of family relationships.
Positively Aware? Conflicting Expert Reviews and Demand for Medical Treatment

We study the impact of expert reviews on the demand for HIV treatments. A novel feature of our study is that we observe two reviews for each HIV drug and focus attention on consumer responses when experts disagree. Reviews are provided by both a doctor and an activist in the HIV lifestyle magazine Positively Aware, which we merge with detailed panel data on HIV-positive men's treatment consumption and health outcomes. To establish a causal relationship between reviews and demand, we exploit the arrival of new drugs over time, which provides arguably random variation in reviews of existing drugs. We find that when doctors and activists agree, more positive reviews increase demand for HIV drugs. However, doctors and activists frequently disagree, most often over treatments that are effective, but have harsh side effects, in which case they are given low ratings by the activist, but not by the doctor. In such cases, relatively healthy consumers favor drugs with higher activist reviews, thus defying the doctor, which is consistent with a distaste for side effects. This pattern reverses for individuals who are in worse health and thus face stronger incentives to choose more effective medication despite side effects. Findings suggest that consumers demand information from experts according to the trade-offs they face when making health investments in the presence of adverse treatment side effects.
Properties of Suprathermal-through-energetic He Ions Associated with Stream Interaction Regions Observed over the Parker Solar Probe’s First Two Orbits

The Integrated Science Investigation of the Sun (IS⊙IS) suite on board NASA’s Parker Solar Probe (PSP) observed six distinct enhancements in the intensities of suprathermal-through-energetic (∼0.03–3 MeV nucleon−1) He ions associated with corotating or stream interaction regions (CIR or SIR) during its first two orbits. Our results from a survey of the time histories of the He intensities, spectral slopes, and anisotropies and the event-averaged energy spectra during these events show the following: (1) In the two strongest enhancements, seen at 0.35 and 0.85 au, the higher-energy ions arrive and maximize later than those at lower energies. In the event seen at 0.35 au, the He ions arrive when PSP was away from the SIR trailing edge and entered the rarefaction region in the high-speed stream. (2) The He intensities either are isotropic or show sunward anisotropies in the spacecraft frame. (3) In all events, the energy spectra between ∼0.2 and 1 MeV nucleon−1 are power laws of the form ∝E−2. In the two strongest events, the energy spectra are well represented by flat power laws between ∼0.03 and 0.4 MeV nucleon−1 modulated by exponential rollovers between ∼0.4 and 3 MeV nucleon−1. We conclude that the SIR-associated He ions originate from sources or shocks beyond PSP’s location rather than from acceleration processes occurring at nearby portions of local compression regions. Our results also suggest that rarefaction regions that typically follow the SIRs facilitate easier particle transport throughout the inner heliosphere such that low-energy ions do not undergo significant energy loss due to adiabatic deceleration, contrary to predictions of existing models.
Fractional Cross Product Applied inRadiation Characteristic of Micro-strip Antenna: A simulation Approach

Fractional Calculus Technique (αth order) is already used in different fields of electronics. In this paper, we have derived the E and H plane equation of micro-strip antenna by using fractional cross product and simulated it to see the effect in the radiation pattern which gives an interesting result and different values of ‘α’ are simulated and compared. This effect can be exploited in future by comparing with the radiation pattern with including fraction order electronics component in the micro-strip antenna.

Do maximalist shoes mitigate risk factors for tibial stress fractures better than stability or flexible (marketed as minimalist) shoes?

Abstract Background: Tibial stress fractures (TSF) are a common running related injury. Specific risk factors include increased rearfoot eversion and increased vertical instantaneous and average loading rates (VILR and VALR, respectively). Since these risk factors are mechanical in nature, certain types of running shoes may be able to reduce these risk factors for TSF. The objective of this study was to determine the effects of maximalist, stability, and flexible (commercially marketed as minimalist) running shoes on specific risk factors for TSF in male and female runners. Methods: Fourteen recreation runners were recruited for this study, 7 males and 7 females. A 14-camera motion capture system and three force plates were used to capture each subject’s kinematics and kinetics. Subjects ran in maximalist (Hoka Bondi 5), stability (Nike Structures), neutral (Nike Pegasus), and flexible (Nike Free) shoes. Results: Among males there was a significant increase in ankle internal rotation ROM in the maximalist shoe compared to neutral. There was also a significant decrease in ankle internal rotation ROM in the flexible shoe compared to neutral. Among females there was a significant reduction in peak ankle eversion and ankle eversion ROM. Conclusions: The results of this study suggest that the maximalist shoes may reduce the pronation component of TSF risk factors in female runners. The maximalist shoes were able to reduce the peak ankle eversion and ROM. This is likely due to the specific design mechanism of the maximalist shoe to control foot motion.
Exploring Consumer Preferences for Subscription Packages in Public Transport Using Smart Card Data

In this paper, consumer preferences for subscription packages in public transport are explored using smart card data. Furthermore, the influence of travel demand on subscription choice is investigated. Additionally, we analyze the effect of the travel demand expenses and the differences between consumers on the decision process. These effects are modeled with six different logit models and a hierarchy in the decision process has been taken into account. Estimation is done by maximum likelihood. Results are based on four years of smart card data from MyOV of 4379 individuals that traveled with the Dutch Railways for more than a year. Overall, we find that travel demand, historical and realized, is a strong indicator of subscription choice and that first class travelers differ in these preferences. In addition, consumer have an economic incentive when choosing their subscription. However, when this subscription is expensive, consumers are not good at predicting their expected expenses. This research attempts to fill a gap in current literature regarding the non-linear pricing plans in public transport.
Coherence and phase synchrony analyses of EEG signals in Mild Cognitive Impairment (MCI): A study of functional brain connectivity

Abstract This paper presents an EEG study for coherence and phase synchrony in mild cognitive impairment (MCI) subjects. MCI is characterized by cognitive decline, which is an early stage of Alzheimer’s disease (AD). AD is a neurodegenerative disorder with symptoms such as memory loss and cognitive impairment. EEG coherence is a statistical measure of correlation between signals from electrodes spatially separated on the scalp. The magnitude of phase synchrony is expressed in the phase locking value (PLV), a statistical measure of neuronal connectivity in the human brain. Brain signals were recorded using an Emotiv Epoc 14-channel wireless EEG at a sampling frequency of 128 Hz. In this study, we used 22 elderly subjects consisted of 10 MCI subjects and 12 healthy subjects as control group. The coherence between each electrode pair was measured for all frequency bands (delta, theta, alpha and beta). In the MCI subjects, the value of coherence and phase synchrony was generally lower than in the healthy subjects especially in the beta frequency. A decline of intrahemisphere coherence in the MCI subjects occurred in the left temporo-parietal-occipital region. The pattern of decline in MCI coherence is associated with decreased cholinergic connectivity along the path that connects the temporal, occipital, and parietal areas of the brain to the frontal area of the brain. EEG coherence and phase synchrony are able to distinguish persons who suffer AD in the early stages from healthy elderly subjects.
Effects of Ferric Citrate Hydrate on Calciprotein Particle Levels and Aortic Arch Calcification Progression in Patients on Maintenance Hemodialysis: A Comparison with Calcium Carbonate

Background: Arterial calcification is a predictive marker in patient on hemodialysis (HD), but the relationship between arterial calcification and calciprotein particles (CPPs) is unclear. Methods: We examined the effects of ferric citrate hydrate (JTT-751) on CPP level and evaluated changes in aortic arch calcification (AoAC) grade in patients on maintenance HD (MHD). In total, 70 MHD patients were enrolled in the study and followed for 24 months. We measured serum CPP levels and fibroblast growth factor 23 (FGF 23) among propensity score-matched MHD patients. One group (n = 35) was treated with CaCO3 and the other (n = 35) was treated with ferric citrate hydrate (JTT-751). AoAC was assessed on chest-X rays. Eligible patients continued the same treatment. Results: All 70 patients completed the study. Serum CPP levels reduced in the JTT-751 group, but were not significantly different in the CaCO3 group. Among patients whose baseline AoAC score (AoACS) was ≤ 4 (median), median AoACS increased from 0 (0 - 3) to 3 (2 - 4) (p 3 group, median AoACS increased from 2 (0 - 2) to 3 (0 - 4) (p < 0.05) and Δ% AoACS was 1 (0% - 3%). Conclusion: These results indicate that the administration of JTT-751 decreased serum CPP levels but did not inhibit AoAC progression in patients on MHD.

Polarization dependence of interferences inside rubidium atomic vapor governing microwave vector E-field metrology

The atom-based metrology technique has been widely accepted because of the SI traceability and dependence only on the physical constants rather than on any artefact. The presented work explains the dependence of the probe absorption on the polarization of the driving fields in the new atom-based spectroscopic technique for microwave electrometry. This work explains the nature of decays between different pathways when the fields are not only $\pi$π or $\sigma$σ polarized but also at an arbitrary angle between the two orientations. It has been shown that when any of the lasers is linearly polarized at an arbitrary angle $0\lt {\theta_{p,c}}\lt\pm\pi /2$0<θp,c<±π/2 to the quantization axis, the observation of the absorption from a correct direction becomes extremely important. The findings in this work can be utilized in the correct determination of the polarization of the incident microwave field along with the E-field amplitude measurement. Further, a challenge has been discussed when the radio frequency (RF) field is weak and cannot give the distinguished separation in the absorption peak. It has been shown that the sensitivity of the sensor can be increased in this case by detuning the RF from the on-resonance frequency.
Subjects of Education Against School, Family and Tribe

Abstract The aim of this paper is to analyze the subject of students at school. Qualitative research method was used in this paper. A study group of 30 students was selected from a school in Altindað District of Ankara. An interview form was developed as a data collection instrument. The data was analyzed thematically by hermeneutic reading. The findings of the paper indicate that students do not have an input, on the contrary, they are subjects in the educational process. The study was carried out within the framework of a new approach, which address students as subjects of education in contrary to the approach, which deals with students as objects of the education process. Therefore, the present paper is thought to be significant, as it attempts to indicate the potentiality of the new approach in describing educational reality.
Relay Node Placement in Wireless Sensor Networks: From Theory to Practice

The increasingly wide utilization of Wireless Sensor Networks (WSNs) in industrial applications outstands the significance of the Delay Constrained Relay Node Placement (DCRNP) problem. Existing algorithms to the DCRNP problem are designed based on the ideal geometric disk wireless channel model, and no real-world deployments are performed to verify the effectiveness of these algorithms. However, the unreliable and unpredictable wireless links in WSNs may lead these algorithms to fail in practice. Therefore, we first conduct extensive real-world deployments under the guidance of existing algorithms to evaluate their performance and to gain some insights for designing practical deployment algorithms. The results exhibit that the WSNs built by existing algorithms have a favorable performance in end-to-end delay but a poor performance in reliability, which is mainly due to the lack of methods ensuring high-quality links. To this end, we first devise a Set-Covering-based Algorithm (SCA) which figures out the DCRNP problem while ensuring the quality of each link better than a given threshold. As our experiments also show that the fault-tolerant topology can significantly improve network reliability, we then design a <inline-formula><tex-math notation="LaTeX">$k$</tex-math><alternatives><mml:math><mml:mi>k</mml:mi></mml:math><inline-graphic xlink:href="ma-ieq1-2962674.gif"/></alternatives></inline-formula>-Set-Covering-based Algorithm (<inline-formula><tex-math notation="LaTeX">$k$</tex-math><alternatives><mml:math><mml:mi>k</mml:mi></mml:math><inline-graphic xlink:href="ma-ieq2-2962674.gif"/></alternatives></inline-formula>SCA) to build fault-tolerant WSNs based on the methodology of SCA. Furthermore, the elaborate analysis proves that both SCA and <inline-formula><tex-math notation="LaTeX">$k$</tex-math><alternatives><mml:math><mml:mi>k</mml:mi></mml:math><inline-graphic xlink:href="ma-ieq3-2962674.gif"/></alternatives></inline-formula>SCA are polynomial-time algorithms, and their approximation ratios are both O(<inline-formula><tex-math notation="LaTeX">$\ln n$</tex-math><alternatives><mml:math><mml:mrow><mml:mo form="prefix">ln</mml:mo><mml:mi>n</mml:mi></mml:mrow></mml:math><inline-graphic xlink:href="ma-ieq4-2962674.gif"/></alternatives></inline-formula>), where <inline-formula><tex-math notation="LaTeX">$n$</tex-math><alternatives><mml:math><mml:mi>n</mml:mi></mml:math><inline-graphic xlink:href="ma-ieq5-2962674.gif"/></alternatives></inline-formula> is the number of sensor nodes.

Measuring Customer Satisfaction When Dining at a Casual Restaurant: An Application of Kisang's Model

The culinary business is being increased rapidly in Pakistan. Usually, Pakistani consumers prefer to eat meals in homes cooked by female members owing to cultural, social and religious reason. In order to bridge up the gap in existing hospitality literature, the objective of this research manuscript is to find out the relation among the dimensions of quality (food quality, service quality and quality of physical environment), customer satisfaction, restaurant image, behavioral intentions and customer perceived value in casual restaurants in a Sukkur city. Data for this research study have been collected from customers of restaurants located in Sukkur city through convenience sampling with a sampling size of 257. Descriptive statistics were computed by using SPSS (24) and Smart PLS (3.0) version was used to test hypotheses. Service quality dimensions of a causal restaurant were found important determinants of the restaurant image and customer perceived value followed by physical environment and service quality; whereas, the physical environment quality was not found to be a significant factor of perceived value of a customer. Additionally, food quality is measured as an important restaurant’s product. Another outcome of the present study exhibited that quality of physical environment holds a substantial positive effect on a restaurant image. The findings indicate quality in food and service is highly important to satisfy customers and make their behavior positive about casual restaurant. Further, as an average temperature remains above 400 in Sukkur city, internal environment of the restaurant is significant as it will affect the mood and perception of customers when they dine in the casual restaurant.
