Comparison of static and electromagnetic field effects on redox system of soybean seedlings

The effects of magnetic fields (MF) on germination and early growth parameters, redox state and the activity of antioxidant system were investigated in soybean (Glycine max L. Merrill) seedlings. The seeds were imbibed in water and then were exposed to a 30 mT static magnetic field (SMF) and a 10 kHz electromagnetic field (EMF) for 4 days, each 5 h. Water uptake of seeds increased after 40 and 120 minutes of the treatment with MF. In comparison with the control group, exposure to EMF significantly increased germination percent of the seeds and vigor index I, II of seedlings while SMF significantly increased vigor index II but had no effect on seed germination. The ratio of fresh weight to dry weight and ferritin content of both MF-treated groups was significantly higher than those of the control group. Treatment with EMF improved radical scavenging capacity of seedlings and reduced membrane leakages. Exposure to MF also protected seedlings from the risk of increase of internal calcium content. The results provide us with a new approach for application of magnetic fields in order to promote growth of strategic crops.
Does screen time and duration of exercise impact cognition levels during COVID-19 lockdown: An observational study

Coronavirus Disease is a novel disease that was first detected in China. There has been a surge in the number of coronavirus cases globally with India having the second-highest number of cases. Due to the prevailing problems, the colleges around the country are closed and education is being imparted through online mode. The use of the online mode of education led to an addition in the screen time of college students. Social restrictions like lockdown led the individuals to confine to their homes thereby causing a reduction of physical activity and exercise duration. Hence, we conducted this study to evaluate the impact of screen time and physical activity on the level of cognitive failure in college students in India. We conducted this explanatory, cross-sectional, online survey with 500 college students from India, and data collection was completed following informed consent. We found that the highest percentage of college students (43%) had a screen time of more than six hours. Subjects having a higher screen time also demonstrated a higher cognitive failure questionnaire score (56.19+20.07). Subjects who performed exercises for more than 29 minutes per day were found to have the lowest cognitive failure score (44.31+22.34). We should take into concern the cognitive failures of college students who are consistently being using digital devices and not doing exercises for an optimal duration. Higher screen time and lower exercise duration might serve as a factor to increase cognitive failure in college students in India.
Observing many researchers using the same data and hypothesis reveals a hidden universe of uncertainty

Significance Will different researchers converge on similar findings when analyzing the same data? Seventy-three independent research teams used identical cross-country survey data to test a prominent social science hypothesis: that more immigration will reduce public support for government provision of social policies. Instead of convergence, teams’ results varied greatly, ranging from large negative to large positive effects of immigration on social policy support. The choices made by the research teams in designing their statistical tests explain very little of this variation; a hidden universe of uncertainty remains. Considering this variation, scientists, especially those working with the complexities of human societies and behavior, should exercise humility and strive to better account for the uncertainty in their work.
Efficacy of whole-body vibration on low bone density in post-burn patients

Introduction. To evaluate the effect of whole-body vibration on low bone mineral density in post-burn patients. Methods. Thirty male post-burn patients were randomly divided into 2 groups. The study group received an intervention of whole-body vibration with following parameters: 30 Hz as vibration frequency, 4–7 mm as amplitude range, and 2.28 g as an acceleration, 3 times per week, 24 weeks, in addition to traditional physiotherapy (exercise program). The control group received traditional physiotherapy (exercise program) only. All patients in both groups were subjected to dual-energy X-ray absorptiometry before and after treatment to estimate the bone mineral density in the lumbar region. Results. There were significant increases in bone mineral density mean values in both groups ( p < 0.05). Also, there was a significant increase in bone mineral density mean value in the study group compared with the control group ( p < 0.05). Conclusions. Whole-body vibration may have a beneficial effect on low bone mineral density in post-burn patients.
Enhancement of Yield and Quality of Guava cv. Lucknow-49 by Foliar Application of Nutrients under High-Density Planting System

In view of the importance of foliar application of macro and micro nutrients to increase the yield and quality of guava under high density planting system, an experiment was laid out in a randomized complete block design consisting of nine treatment combinations with three replications. [(Control - Fertigation alone), (NPK (19:19:19)), (NPK + Zn), (NPK + Ca), (NPK + B), (NPK + Zn + Ca), (NPK + Zn + B), (NPK + Ca + B), (NPK + Zn + Ca + B). Among the treatments, fruit weight (225.22 g), fruit volume (215.35 ml),number of fruits per plant (80.35), fruit yield per plant(17.67 kg plant-1), TSS(10.60 0Brix), titratable acidity (0.196 %) and pectin content (1.31 %) was found to be significantly higher with the foliar application of NPK @ 1% + Zn @ 0.5 % + B @ 0.4%. The foliar spray of NPK @ 1% + Ca@ 0.2% + B@ 0.4% significantly increased the fruit diameter (7.85 cm), and ascorbic acid content (159.84 mg 100g-1). Thus, foliar spray of NPK, zinc and boron maintained more number of fruits per plant and improved the fruit set leading to an 18% increase in yield. Whereas, the addition of calcium to the plants increased the ascorbic acid content of the fruit and pectin that enhanced the shelf life of the fruit
Effects of cardiorespiratory fitness and muscular strength on the association between arterial stiffness and depression in older adults

Purpose: To determine the effects of objectively measured cardiorespiratory fitness (CRF) and muscular strength (MS) on the association between arterial stiffness and depression in older adults. Methods: This cross-sectional study included 596 older adults aged ≥65 years (mean age 72 years). Carotid-femoral pulse wave velocity (PWV) was used to assess arterial stiffness (AtCor, Sphygmocor Xcel). Depression was defined as participant taking current anti-depressant medication or scoring ≥5 in the Geriatric Depression Scale. CRF was assessed by time (seconds) to complete a 400-m walk test and MS by overall grip strength (maximum out of 3 trials on each hand, averaged; Jamar Plus+ 12-064). Logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs) of having depression across age and sex specific tertiles of PWV. Participants were further dichotomized into CRF levels, fit (upper 2/3 of CRF) or unfit (lower 1/3 of CRF), or into MS levels, strong (upper 2/3 of MS) or weak (lower 1/3 of CRF) to test the combined associations PWV and CRF, and PWV and MS with depression. Results: Seventy-three (12 %) older adults were identified as having depression. Higher arterial stiffness was not found to be associated with depression across PWV tertiles [compared to the lower PWV tertile, the odds of having depression were 0.88 (0.46, 1.69) and 1.19 (0.59, 2.36), for the middle and upper PWV tertile, respectively (p=0.66 for linear trend)]. Although not significant, among fit participants, the middle and upper PWV tertiles had lower odds of depression [0.79 (0.35, 1.77) and 0.72 (0.27, 1.89), respectively, compared to the lower PWV tertile], however, among unfit participants, the middle and upper PWV tertiles had higher odds of depression [1.35 (0.38, 4.88) and 2.50 (0.73, 8.55), respectively, compared to the lower PWV tertile]. Although not significant, among strong participants, the middle and upper PWV tertiles

Precision mass measurements using the Phase-Imaging Ion-Cyclotron-Resonance detection technique

This thesis presents the implementation and improvement of the Phase-Imaging Ion-Cyclotron-Resonance (PI-ICR) detection technique at the ISOLTRAP experiment, located at the ISOLDE / CERN, with the purpose of on-line high-precision and high-resolution mass spectrometry. Extensive simulation studies were performed with the aim of improving the phaseimaging resolution and finding the optimal position for detector placement. Following the outcome of these simulations, the detector was moved out of a region of electric-field distortion and closer to the center of the Penning trap, showing a dramatic improvement in the quality and reproducibility of the phase-imaging measurements. A new image reconstitution and analysis software for the MCP-PS detector was written in Python and ROOT and introduced in the framework of PI-ICR mass measurements. The state of the art in the field of time-of-flight ion-cyclotron-resonance measurements is illustrated through an analysis of on-line measurements of the mirror nuclei 21Na/Ne and 23Mg/Na using the Ramsey excitation pattern. The Q-values determined from this analysis play an important role for verifying the Conserved-Vector-Current hypothesis and for testing the unitarity of the CKM quark-mixing matrix. Finally, the results of a first high-precision, on-line measurement using the PI-ICR technique are presented, addressing the Q-value of the 88Rb-88Sr β-decay. Kurzfassung Diese Arbeit präsentiert die Implementierung und Verbesserungen der "Phase-Imaging IonCyclotron-Resonance" (PI-ICR) Detektionstechnik am ISOLTRAP-Experiment an ISOLDE / CERN in Hinblick auf Hochpräzissionsmassenspektrometrie, sowie deren erste Online-Ergebnisse. Ausführliche Simulationen wurden mit dem Ziel durchgeführt, die Phasenbildauflösung zu vergrößern und eine optimale Detektorposition zu finden. Als Ergebnis dieser Studien wurde der Detektor aus einem Bereich mit starken, elektrischen Streupotenzialen näher zum Fallenzentrum hin versetzt. Dies führte zu einer signifikanten Verbesserung der PIICR Messungen sowie zur Reproduzierbarkeit von optimalen Potentialparametern. Zudem wurde eine neue Bildrekonstruktionsund Analysesoftware für PI-ICR-Messungen in Python und ROOT geschrieben. Die bisher für Hochpräzisionsmassenmessung an kurzlebigen Nukliden am weitesten verbreitete Methode (die "Time-of-Flight Ion-Cyclotron-Resonance" (ToF-ICR) Detektionstechnik mit Ramsey-Anregungsschema) wird im Rahmen einer Analyse von Onlinemessungen der Spiegelkerne 21Na/Ne und 23Mg/Na vorgestellt. Der Q-Wert dieser Zerfälle spielt eine wichtige Rolle bei der Überprüfung der Vektorstrom-Erhaltungshypothese (engl. Conserved-Vector-Current hypothesis). Außerdem können die neu gewonnen Ergebnisse für den Unitaritätstest der Cabibbo-Kobayashi-Maskawa (CKM) Quarkmischungsmatrix herangezogen werden. Zusätzlich werden erste Hochpräzisionsmassenmessungen mittels PI-ICR an online erzeugten, radioaktiven Isotopen vorgestellt. Hierbei wurde der QWert des 88Rb-88Sr-β-Zerfalls bestimmt und mit Literatursowie ToF-ICR-Messwerten verglichen.
The role of cannabinoids in the management of symptoms in palliative care patients

The endocannabinoid system (ECS) regulates body’s homeostasis and performs vital physiological functions. The thorough understanding of the role of endocannabinoids and the composition of cannabis containing phytocannabinoids and terpenoids play an important role in symptom management. Clinical effects of medical cannabis depend among others on the activity of the ECS in a given patient, the proportion of phytocannabinoids, and the doses used. Cannabinoids are used to treat symptoms in patients with cancer and chronic non-malignant diseases. Cannabinoids are usually not drugs of first choice and can be added to basic pharmacotherapy, which often improves the effectiveness of symptom treatment. Due to limited scientific evidence, experimental studies on the role of the ECS and clinical trials on the use of cannabinoids in the treatment of symptoms are recommended. In this article the role of the ECS and the use of cannabinoids in palliative care patients has been discussed.
Awareness, knowledge and screening for cervical cancer among women of a faith-based organization in Nigeria

Introduction cervical cancer is the second most frequent cancer among women in Nigeria. With proper screening, the disease can be detected early enough and properly managed. However, there seems to be limited knowledge of cervical cancer among women and several barriers might prevent them from accessing the screening services. We determined the awareness, knowledge and screening for cervical cancer among women of a faith-based organization in Nigeria. Methods we employed descriptive survey research design and purposively sampled a Catholic Parish in Nsukka Local Government Area of Enugu State, Nigeria. All consenting women in the Parish were used for the study. We utilized researchers' structured instrument titled ‘Awareness and knowledge about Cervical Cancer and Screening’ to collect data. Frequencies, percentages and logistic regression were employed for data analysis. Results awareness of cervical cancer (70.8%) and its screening (68.1%) are high but there is generally poor level of knowledge (65.3%) of different aspects of cervical cancer among the women. Age (aOR: 7.183, 95% CI 1.769-29.168; p=.006), number of children (aOR: .074, 95% CI .009- .631; p=.017), and occupation (aOR: .032, 95% CI .004-.260; p= .001 and aOR: .050, 95% CI .007-.347; p=.002) were significantly associated with knowledge of cervical cancer. Majority of the women studied had never been screened for cervical cancer (91.7%) and the reasons for not screening ranged from lack of knowledge of; where to go for screening (69.7%) and the importance of being screened (40.9%) to not feeling susceptible to cervical cancer (18.2%). Conclusion there was generally poor knowledge of cervical cancer and its screening; and very poor screening practice. There is, therefore, an urgent need to improve women´s knowledge of cervical cancer and address the identified barriers in order to improve screening practices of the women.
The Validity and Reliability of Three Field Tests for Assessing College Freshmen Students' Cardiovascular Endurance

In an effort to reduce obesity rates among young adults resulting from their increasingly sedentary and stressful lifestyle and poor diet, three common endurance exercises that have been practiced in PE classes and also studied worldwide are jumping rope, step test, and beep test (20 meter multistage fitness test). This study shed light on the suitability of these three field tests as assessment tools for measuring the cardiovascular endurance of the college freshmen students of Physical Fitness (HKD-01) course since none has been investigated so far about this in the Philippine university context. Specifically, this study aimed to identify (1) the validity of the three tests as assessment tools for gauging cardiovascular fitness; and (2) their reliability as shown in the correlation between the directly measured and predicted VO2 max. The statistical analyses revealed that the fitness tests were found valid and reliable. Each fitness test has its own peculiarity and course of action that make each distinct from one another. The step test is known to measure submaximal, the jumping rope test can be categorized as mid-maximal, and the beep test is known as a maximal test for cardiovascular endurance. It is then recommended that these fitness tests be employed in PE classes in the university following correct protocols to develop the cardiorespiratory endurance of the students.
A Cross-Sectional Study of prevalence of Prostate lesions and inter-Observer Variability in Histopathological Reporting

Introduction: To report the prevalence of various prostate lesions in the general population through cadaver prostates and to determine the interobserver variability for reporting high-grade lesions of the prostate. Materials and Methods: The cross-sectional study was carried out on 110 autopsy specimens of healthy prostate with deceased age over 40 years. The specimens were grossed, sectioned, stained and reported independently by the primary investigator resident and the senior professor. The lesions were categorized into prostatitis, benign prostate hypertrophy (BPH), prostate intraepithelial neoplasia (PIN) further graded as low grade (LGPIN) and high grade (HGPIN) and prostate cancer (PCa). Inter-rater kappa agreement was used to find the strength of agreement between the pathologists. Results: Among 110 prostate specimens, only 8(7.27%) cases had normal prostate with 72 (65.4%) having BPH and 12(10.9%) cases having prostatitis. There were 17 cases of PIN with 11 cases of HGPIN and 6 cases of LGPIN. Malignancy was seen in only a single case (95% Confidence Interval: 0% - 2.71%). The primary resident missed 4 cases of HGPIN and 2 cases of LGPIN. Interobserver agreement between the resident and senior pathologist was fair (Kappa 0.282, p value=0.335). Conclusion: In conclusion, prostate lesions remain latent and show high prevalence in general population without causing any symptoms. The study depicts a high interobserver variability of reporting the high-grade lesions of prostate since they cause a diagnostic dilemma with PCa. The consultation with uropathologists and use of molecular markers must be included in the diagnostic panel while reaching a final diagnosis.
Clinical experience with noninvasive prenatal testing in Germany: Analysis of over 500 high-risk cases for trisomy 21, 18, 13 and monosomy X

Analysis of 545 NIPT high-risk cases with high risk for trisomy 21 (T21), 18 (T18), and 13 (T13), as well as monosomy X (MX) from routine NIPT testing in a single prenatal center in Germany. Analysis was performed using the VeriSeq NIPT Solution v2 (Illumina Inc., USA). The assessment of true vs false positive results were based on clinical outcome data. The average fetal fraction of 9.7% was within the expected range in T21 and MX but lower in T18 and T13. For all high-risk groups sensitivity and specificity was far above 99%. The positive predictive value (PPV) was highest at trisomy 21 with 94.1%, followed by trisomy 18 with 80.9%. For trisomy 13 and Monosomy X, the PPV was clearly lower at 60.5% and 65.6%, respectively. PPV was dependent on different indications and maternal age. We could show that statistical tools of the method like the log likelihood ratio (LLR) score and T-Statistics value are important to distinguish between (clinical) false positive and true positive NIPT results in trisomies. The relationship between results and quality scores is less significant for MX cases. The study shows that the Illumina VeriSeq v2 procedure is a highly reliable NIPT method with a low no call rate in the hands of experienced diagnostic laboratories.
3Φ4W Hybrid Frequency Parallel Uninterruptable Power Supply for Reducing Voltage Distortion and Improving Dynamic Response

This article presents a three-phase four-wire ( $3\Phi 4\text{W}$ ) hybrid frequency parallel uninterruptable power supply (HbFPUPS) with ripple compensation to reduce output voltage distortion and improve dynamic response for high power UPS applications. An HbFPUPS is composed of a low-frequency-high-power uninterruptible power supply (LFUPS) and a high-frequency-low-power uninterruptable power supply (HFUPS) connected in parallel. LFUPS tracks the major load currents with lower frequency (LF) insulated gate bipolar transistors (IGBTs) while HFUPS regulates the output voltage and compensates the current ripples of LFUPS with higher frequency (HF) SiC MOSFETs. For multifrequency parallel inverters, ripple compensation control reduces LF ripples and mitigates multifrequency ripple issue in filter design when interleaved switching is not available. Compare with conventional single and parallel inverters with identical frequency and power, HbFPUPS provides a sufficient dynamic response without overdesigning the system with high-power-high-frequency costly SiC MOSFETs, or trading off efficiency for higher switching frequency operation on IGBTs. The remaining HF ripple and increased dynamic response reduce filter inductance and capacitance. In this article, control, parameter design, voltage regulation performance, and stability of HbFPUPS are analyzed. Voltage distortion, ripple, and transient error reductions are validated with the 300-kVA simulated and 10-kVA experimental results of a HbFPUPS in linear, rectified, and step-up/down load tests.
