ABSTRACT
To investigate the sensitivity of slip inversions to station distribution and choice of empirical Green’s function (EGF), we examine three microearthquakes that occurred within the high-density LArge-n Seismic Survey in Oklahoma (LASSO) nodal seismic array. The LASSO array’s dense distribution of 1825 geophones provides an exceptional level of spatial and azimuthal coverage, allowing for more accurate inversions of slip than are possible with typical station distributions. The highly accurate slip inversions, in turn, allow for the exploration of the sensitivity of slip inversions to station distribution and parameter choices. We examine the effects of these choices using three well-recorded strike-slip microearthquakes (ML 1.7, 2.3, and 2.7) using an EGF method. From this analysis and the systematic testing of varied network arrangements, we find that station distributions that have uniform coverage of azimuth and distance can retrieve the overall pattern of slip, but the estimated amplitude of slip can vary by 30% for high-slip regions due to small variations in station location. In addition, we find that the distance range that accurately resolves the overall pattern of slip is the one that contains the takeoff angles of 45°–65°. Concerning azimuthal coverage, a network with &gt;270° performs similarly to having complete coverage. The choice of EGF can shift the location of resolved areas of slip and their amplitude, depending on its similarity in location and radiation pattern to the target earthquake.

Published: February 2022

Background: The most important predictor of oocyte yield in ART cycles is female age, but other biochemical and ultrasonographic markers done before controlled ovarian stimulation may predict the oocyte yield in women undergoing COS in IVF cycles.Methods: The main aim of the study was to evaluate ovarian reserve markers before COS which can help to individualise treatment protocols to achieve optimal response and minimise risk of complications. It is retrospective observational study, 1924 women undergoing COS in IVF/ICSI cycles in tertiary care centre in India, from January 2010 to June 2017 were included. Results: Univariate analysis showed that age, D2FSH, AMH, D2AFC and E2 on the day of trigger were significant predictors of oocyte yield (p<0.05). E2 on day of trigger with ROC (0.81), indicating good discriminating potential for predicting poor ovarian response, followed by age and D2 FSH. The formula to calculate, number of oocytes retrieved=18.46+(0.174×AFC)+(0.092×AMH)-(0.123×age)-(1.19×FSH), FSH was formulated, with r2=0.2486 (p<0.001). ROC curve analysis shows that FSH has statistically significant discriminability to detect poor response than age [AUC (95% CI) FSH 0.77 (0.74, 0.81), age 0.56 (0.52, 0.60), (p<0.05)]. FSH >7.82 IU/ml was predictor of poor response (sensitivity 78.13%, specificity 79.53%).Conclusions: A combination of predictors demonstrated superior ability of predicting oocyte yield after controlled ovarian stimulation than compared with any single endocrine marker. D2 FSH though thought to be obsolete, but we found significant predictive ability in terms of oocyte yield in the Indian population.

Published: February 2022

Background: Cytokines are major immune regulators, which play a critical role in the pathophysiology of unexplained recurrent pregnancy loss. Th1 class of cytokines has been shown to exert deleterious effects on pregnancy causing early loss.Methods: The changeover in the levels of Th1 cytokines was studied in two major groups; Gp I (N=30) comprised of RPL subjects with two or more consecutive spontaneous miscarriages history and Gp II (N=30) comprised of normal pregnancy controls .The efficacy of oral micronized progesterone was assessed in regulation of cytokine levels ,with Gp Ia (N=15) treated with 200 mg oral micronized progesterone and Gp Ib (N=15) comprised of untreated RPL subjects and its role in improving pregnancy outcome was also determined. The present study determined the levels of cytokine TNF-α, IL-6 and PTX-3 in serum samples for all the subjects at three time points at the time of enrolment, with (GpIa) or without (Gp Ib) progesterone administration at 20 weeks or abortion if earlier and at the time of delivery. Results: The results indicated that the levels of Th1 cytokines (TNF-α [37.80 versus 78.09], IL-6 [16.93 versus 81.12] and PTX-3 [17.42 versus 73.53]) was found to be reduced at every time point in the treated cases with an RPL history as compared to untreated ones. Further, the cases treated with with oral micronized progesterone were found to have better pregnancy outcomes (p<0.005 significant number of live births).Conclusions: The levels of interlukins, TNF-α, IL-6, PTX-3 in cases of RPL may not have a major contributory role in predicting outcome, however exogenous progesterone decreases the Th1 pro inflammatory response and efficiently improves the pregnancy outcomes by modulation of cytokine levels.

Published: February 2022

Background: The aim of the study was to evaluate the association between levels of second trimester C Reactive protein (CRP) with adverse pregnancy outcomes.Methods: Present study was a prospective analytical study carried out among 359 pregnant women between 14-18 weeks. All were primigravida, who attended antenatal OPD at RGGWCH between January 2019 to June 2020. All subjects fulfilled inclusion and exclusion criteria. Informed written consent was obtained in each case. A detailed history, clinical and ultrasound examination was done to confirm the gestational age. Then blood was collected and sent for serum CRP estimation. Patients were followed upto discharge of the mother and baby and fetomaternal outcome studied. Once the sample size was attained, the correlation between CRP levels and fetomaternal outcome was studied. Results: Increased levels of serum CRP in early second trimester in primigravida were significantly associated with adverse pregnancy outcomes like preterm delivery (p value 0.001), PROM (premature rupture of membranes) (p value 0.01) and low APGAR (p value 0.01).Conclusions: Early detection of higher levels of serum CRP in pregnancy can be used as predictor of inflammation and may help in early intervention, follow up and timely referral of the patients to minimize adverse maternal and fetal complications.

Published: February 2022

The aim of the paper is to evaluate alternative food networks (farmers’ markets and community gardens) in Slovak towns in order to determine the views of town self-governing authorities. Data was collected through a questionnaire sent to representatives of towns. The results have shown that only 39% of towns regularly organise farmers’ markets but, overall, 52% of towns support or plan to support their organisation. There are a total of 40 community gardens in 17 towns, mainly in the west of Slovakia. The paper discusses the ways in which Slovak towns support alternative food networks.

Effects of structured education and a physical activity prescription during prenatal care on maternal and fetal outcomes: A quasi-experimental study
Authors: Saidi Latifa , Godbout Pierre D. , Morais-Savoie Camille , Bélanger Mathieu 
Published: February 2022

Abstract
Background: Physical activity (PA) during pregnancy is associated with healthy gestational weight gain (GWG) and a reduction in risk of developing gestational diabetes (GD), hypertension (GHT) and fetal macrosomia. However, less than 20% of pregnant women meet the PA recommendations in Canada. We tested the effects of PA education and a PA prescription by prenatal nurses and physicians on fetal and maternal outcomes.Methods: Administrative data from two periods with distinct prenatal care offering were used. In the first period, 394 pregnant women followed at the obstetrics clinic of a university hospital received standard care whereas 422 women followed in the second period received standard care supplemented with education on the relevance of PA during pregnancy and a prescription for PA. Logistic regressions were used to compare odds of excessive GWG, GD, GHT, and fetal macrosomia between the two study groups.Results: The addition of PA education and PA prescription to prenatal care was associated with a 29% reduction in odds of excessive GWG (adjusted OR 0.71, 95% CI 0.51-0.99), 73% reduction in odds of GHT (0.27, 0.14-0.53) and 44% reduction in odds of fetal macrosomia (0.56, 0.34-0.93). The intervention was not associated with different odds of GD (0.48, 0.12-1.94). Conclusions: The inclusion of education and prescription of PA as part of routine prenatal care can lead to significant improvements in maternal and fetal health outcomes.
Research Trends in Japanese Public Administration: Statistical Content Analyses of Article Titles in Public Administration Review Quarterly (1978–2019)
Authors: Moteki Yasutoshi 
Published: February 2022

Abstract
This paper quantitatively explains research trends in postwar administrative studies in Japan using statistical analyses of nearly 40 years of article titles from the Public Administration Review Quarterly, from its first (1978) to 165th issue (2019). Published quarterly by the Institute of Administrative Management, which is tied to the Ministry of Internal Affairs and Communications, this is a renowned journal in public administration in Japan. The co-occurrence network analysis and correspondence analysis revealed changes in research interests. There was substantially more research on administrative reforms through the postwar Showa and Heisei eras. The configuration figures of the correspondence analysis indicate that the first dimension concerns administrative reforms, the second concerns historical events/administrative systems, and the third concerns evaluations and Kaizen. The co-occurrence network analysis showed that studies during the Showa era (1978–1988) could be partly characterized by two extracted compound words: the United States and the United Kingdom. In other words, public administration in Japan in this period was strongly influenced by Western public administration. Japan became a feature of studies of public administration during the Heisei era (1989–2018). These features are consistent with those found in previous quantitative studies.
Can Current Reanalyses Accurately Portray Changes in Southern Annular Mode Structure Prior to 1979?
Authors: Marshall Gareth , Fogt Ryan L. , Turner John , Clem Kyle R. 
Published: February 2022

Abstract
Early reanalyses are less than optimal for investigating the regional effects of ozone depletion on Southern Hemisphere (SH) high-latitude climate because the availability of satellite sounder data from 1979 significantly improved their accuracy in data sparse regions, leading to a coincident inhomogeneity. To determine whether current reanalyses are better at SH high-latitudes in the pre-satellite era, here we examine the capabilities of the European Centre for Medium-range Weather Forecasts (ECMWF) fifth generation reanalysis (ERA5), the Twentieth Century Reanalysis version 3 (20CRv3), and the Japanese Meteorological Agency (JMA) 55-year reanalysis (JRA-55) to reproduce and help explain the pronounced change in the relationship between the Southern Annular Mode (SAM) and Antarctic near-surface air temperatures (SAT) between 1950–1979 (EARLY period) and 1980–2020 (LATE period). We find that ERA5 best reproduces Antarctic SAT in the EARLY period and is also the most homogeneous reanalysis across the EARLY and LATE periods. ERA5 and 20CRv3 provide a good representation of SAM in both periods with JRA-55 only similarly skilful in the LATE period. Nevertheless, all three reanalyses show the marked change in Antarctic SAM-SAT relationships between the two periods. In particular, ERA5 and 20CRv3 demonstrate the observed switch in the sign of the SAM-SAT relationship in the Antarctic Peninsula: analysis of changes in SAM structure and associated meridional wind anomalies reveal that in these reanalyses positive SAM is linked to cold southerly winds during the EARLY period and warm northerly winds in the LATE period, thus providing a simple explanation for the regional SAM-SAT relationship reversal.

Abstract
Purpose–Tuberculous cervical lymphdaenopathy is the most common manifestation of extrapulmonary tuberculosis and frequently present imaging diagnostic dilemma with metastatic lymphadenopathy. Ours is observational study done to evaluate the role of sonography including Doppler and strain elastography in tubercular cervical lymphadenopathy.Methods-100 fine needle aspiration cytology/histopathological examination(FNAC/HPE) proven tubercular lymph nodes were evaluated with sonography and strain elastography Features evaluated with sonography are location, size, short/long axis diameter(S/L) ratio, presence or absence of echogenic hilum ,intra-nodal necrosis, intra-nodal calcification associated soft tissue features like periadenitis or collection and pattern of vascularity. With strain elastography(USE) color coded elastograms and strain ratio were evaluated. Results-On evaluation tubercular nodes are large size, S/L ratio >0.5, show intra-nodal necrosis and peripheral vascular pattern. 91% tuberculous lymph nodes had color coded elastograms>2 pattern which is similar to malignant lymph nodes and 99% of tuberculous lymph nodes show strain ratio< 1.99.Conclusion - Grey scale and Doppler assessment of tubercular lymph nodes reveals findings similar to that encountered in metastatic nodes, hence differentiation difficult .While strain ratio being semi-quantitative is more objective criteria of assessment compared to color coded elastograms. Hence adding semi-quantitative elastographic evaluation with US will help in further characterization of tuberculous nodes.

Published: February 2022

Abstract
Purpose: Bulimia nervosa (BN) and anorexia nervosa (AN) are potentially life-threatening eating disorders (ED) that primarily affect young people, mostly women. The central common pathology is linked to the relationship with food and with abnormalities in food intake.A previous study indicated that individuals with ANtend to overestimate food portion sizes compared to healthy controls (HC), but no study has investigated these patterns in BN, which was the objective of this study.Methods: Women with BN (27), AN (28), and HC (27) were asked to rate different meal portion sizes in two conditions: as if they were supposed to eat them (intent-to-eat condition) or in general (general condition). BN results were compared to HC and AN using mixed model analyses.Results: BN showed larger estimations compared to HC, while smaller estimations compared to AN. These differences were found mostly for intermediate portion sizes. No difference for conditions (intent-to-eat; general) was found between groups.Conclusion: When estimating food portion sizes, individuals with BN seem to fall intermediately between HC and AN. ED symptoms in BN were most strongly associated with higher portion estimation. This might therefore reflect one aspect of the cognitive distortions typically seen also in AN.A therapeutic option could include the frequent visual exposure to increasing portions of food, what may serve to recalibrate visual perceptions of what a “normal-sized” portion of food looks like.Level of evidenceLevel II: Evidence obtained from well-designed controlled trials without randomization.

Abstract
Colloidal lead halide perovskite (LHP) nanocrystals (NCs, with bright and spectrally narrow photoluminescence (PL) tunable over the entire visible spectral range, are the latest generation of semiconductor quantum dots (QDs) of immense interest as classical and quantum light sources. LHP NCs form by sub-second fast and hence hard-to-control ionic metathesis reactions, which severely limits the access to size-uniform and shape-regular NCs in the sub-10 nm range. We posit that a synthesis path comprising an intricate equilibrium between the precursor (PbBr2) and the Cs[PbBr3] solute for the QD nucleation may circumvent this challenge. Here, we report a room-temperature synthesis of monodisperse, isolable spheroidal CsPbBr3 QDs, size-tunable in the 3-13 nm range. The kinetics of both nucleation and therefrom temporally separated growth are drastically slowed down by the formation of transient Cs[PbBr3], resulting in total reaction times of up to 30 minutes. The methodology is then extended to FAPbBr3 (FA = formamidinium) and MAPbBr3 (MA = methylammonium), allowing for thorough experimental comparison and modeling of their physical properties under intermediate quantum confinement. In particular, QDs of all these compositions exhibit up to four excitonic transitions in their linear absorption spectra and we demonstrate that the size-dependent confinement energy for all transitions is independent of the A-site cation.
The Role of CGRP Inhibition and High-Intensity Interval Training (HIIT) on Mtorc2 and VEGF Gene Expression in The Hippocampal Tissues of Male Wistar Rats

Published: February 2022

Abstract
Background
The hippocampus, as one of the most critical regions of the brain, is significantly affected by exercise. The primary purpose of this study is to evaluate the effect of six weeks of high-intensity interval training (HIIT) and inhibition of calcitonin gene-related peptide (CGRP) on gene expression of vascular endothelial growth factor (VEGF) and serine/threonine type 2 kinase protein (mTORC2) in hippocampal tissue of male Wistar rats.
Methods
Thirty-two healthy male Wistar rats (8 weeks of age) were randomly assigned to one of four groups: control, CGRP inhibition, HIIT+CGRP inhibition, or HIIT. The CGRP inhibition group received 0.25 mg/kg/day of antibody intraperitoneally. The animals in the training groups underwent high-intensity interval training (HIIT, ten 2-minute work bouts per day at 22 m/min interspersed by 2-minute rest periods, five days/week). Real-time PCR (2-ΔΔCT) and one-way ANOVA were employed to measure the expression of genes and analyze the data, respectively.
Results
HIIT significantly enhanced VEGF (p≤0.002) and mTORC2 (p≤0.006) gene expression in the hippocampal tissue compared to the control group. HIIT+CGRP inhibition resulted in a substantial increase in VEGF expression compared to the control group (p≤0.007). While HIIT+CGRP inhibition significantly lowered mTORC2 gene expression (p≤0.001), HIIT alone did not (p≤0.001).
Conclusions
HIIT-induced physiological alterations in the hippocampus can improve the brain’s functional status via upregulation of VEGF and mTORC2 gene expression as an effective non-pharmacological method. Additionally, HIIT+CGRP inhibition may represent a new approach via the VEGF and mTORC2 pathways in the hippocampus.

Abstract
Sediments act as a sink or source of pollution under various conditions. Moreover, they can serve as pollution indicators. The present research aims to evaluate sediment quality associated with its content in heavy metals and the potential ecological risk, focusing on the sub-branches of Nile River (Rayahs) in Egypt, including El-Tawfiky (RT), El-Menoufy (RM), El-Behary (RB), and El-Nassery (RN). According to the results, El-Rayahs sediments are characterized by an increasing sand fraction, followed by mud. Regarding metals pollution, Cd registered the highest pollution ranking, whereas Fe, Mn, Zn, Pb, and Ni exhibited the lowest effect. Furthermore, the ecological risk for El-Rayahs sediments increases northward; however, most sites either showed slight pollution or did not record any degree of contamination, except the northern stretch of El-Behery (El-Mahmoudia Canal), which is a very high-polluted zone, with high ecological risk according to the contamination degree (Cd) and potential ecological risk (RI) indices.
