Biological Predictors of Postpartum Depression: A Literature Review
Authors: Parasian Leonard Chandra 
Published: April 2022

Introduction. Maternal mental health problems pose major public health challenges for societies across the globe. PPD affects between 13–19% of women worldwide and has negative consequences on the woman herself and on her entire family. PPD has negative consequences on the woman herself and on her entire family. Biological models of PPD can be conceptualized as withdrawal models that concern the fact that reproductive hormones and stress hormones rise dramatically prior to delivery. A few studies have attempted to identify biological aspect as a predictor of PPD.
Method: Searches were conducted in PubMed. The following keywords were applied in the database during the literature search: “Postpartum Depression” OR “Postnatal Depression” OR “Puerperal Depression” AND “Predictor”. Study was considered if they were published between January 2010 and August 2021, English language journals. 34 articles were identified. Abstracts were reviewed by researcher and 4 were eliminated. The researcher then reviewed full text of the remaining 26 articles. After full text review, an additional 15 articles did not meet inclusion criteria. The total of 10 articles were identified that met inclusion and exclusion criteria.
Result: Partial reviews are available that cover biological processes broadly, with emphasis on the endocrine system, the immune system and genetic factors. Endocrine system includes estrogen, progesterone, prolactin, oxytocin, and testosterone. For stress hormone take a part like corticotropic releasing hormone, adrenocorticotropic hormone, β-Endorphin, cortisol, dan catecholamine. The cytokine and C-reactive protein are a group of immune system. The latter is serotonin, MAO-A, estrogen receptor, oxytocin, glucocorticoid, and brain derived neurotropic factor.
Conclusion: Postpartum depression is a common but treatable condition. Appropriate and timely treatment is crucial in order to help women cope with their situation and reduce the devastating consequences. It is likely that the dramatic hormonal changes occurring in the postnatal period also play a significant role in the etiology of PPD, but the exact nature of these influences remains unknown, and needs further research.
Observation of nociceptive detection thresholds and cortical evoked potentials: Go/no-go versus two-interval forced choice

Published: April 2022

AbstractPain scientists and clinicians search for objective measures of altered nociceptive processing to study and stratify chronic pain patients. Nociceptive processing can be studied by observing a combination of nociceptive detection thresholds and evoked potentials. However, it is unknown whether the nociceptive detection threshold measured using a go-/no-go (GN) procedure can be biased by a response criterion. In this study, we compared nociceptive detection thresholds, psychometric slopes, and central evoked potentials obtained during a GN procedure with those obtained during a two-interval forced choice (2IFC) procedure to determine (1) if the nociceptive detection threshold during a GN procedure is biased by a criterion and (2) to determine if nociceptive evoked potentials observed in response to stimuli around the detection threshold are biased by a criterion. We found that the detection threshold was higher when assessed using a GN procedure in comparison with the 2IFC procedure. During a GN procedure, the average P2 component increased proportionally when averaged with respect to detection probability, but showed on-off behavior when averaged with respect to stimulus detection. During a 2IFC procedure, the average P2 component increased nonlinearly when averaged with respect to detection probability. These data suggest that nociceptive detection thresholds estimated using a GN procedure are subject to a response criterion.
Ultrafast signatures of magnetic inhomogeneity in Pd1-xFex (x ≤ 0.08) epitaxial thin films

Published: April 2022

A series of Pd1-xFex alloy epitaxial films (x = 0, 0.038, 0.062, and 0.080), a material promising for superconducting spintronics, was prepared and studied with ultrafast optical and magnetooptical laser spectroscopies in a wide 4 – 300 K temperature range. It was found that the transition to the ferromagnetic state causes the qualitative modification of both the reflectivity and the magnetooptical Kerr effect transients. Nanoscale magnetic inhomogeneity of the ferromagnet/paramagnet type inherent in the palladium-rich Pd1‑xFex alloys reveals itself in an occurrence of a relatively slow, 10-25 ps, photoinduced demagnetization component following a subpicosecond one; the former vanishes at low temperatures only in the x = 0.080 sample. We argue that the 10-ps timescale demagnetization originates most probably from the d-electron diffusive transport in the conditions of the nanometer-scale magnetic inhomogeneity. The low-temperature amount of the residual paramagnetic phase can be deduced from the magnitude of the slow reflectivity relaxation component, and is estimated as ~ 30% for x = 0.038 and ~ 15% for x = 0.062 films. The minimal iron content ensuring the magnetic homogeneity of the ferromagnetic state in Pd1-xFex alloy at low temperatures is about 7-8 at.%.

Published: April 2022

AbstractThe idea of ecological boarding school is actually not a new idea in the of Islamic boarding school. Islamic boarding schools as the oldest educational institutions in Indonesia are already familiar with ecological studies, both in the fields of interpretation of the Qur'an, Hadith, Fiqh, and the yellow book which become the basis of their knowledge. However, it is still theoretical and has not yet fully implemented. This study uses library research in the form of searching the latest books, books and journals. This paper concludes that it is time for Islamic boarding schools to transform their scientific treasures, especially those related to ecology, into a real movement. Islamic boarding schools must return to their identity as agents of social change by utilizing the scientific treasures, their community and human resources they have by creating ecological boarding schools.

Abstract
The compact steep-spectrum radio source 3C 298 (redshift of 1.44) has the largest 178 MHz luminosity in the Third Cambridge Revised Catalogue (3CR); its radio lobes are among the most luminous in the universe. The plasma state of the radio lobes is modeled with the aid of interferometric radio observations (in particular, the new Low Frequency Array observation and archival MERLIN data) and archival single-station data. It is estimated that the long-term time-averaged jet power required to fill these lobes with leptonic plasma is

Supporting this notion of extraordinary jet power is a 0.5–10 keV luminosity of ≈ 5.2 × 1046 erg s−1, comparable to luminous blazars, yet there is no other indication of strong relativistic beaming. We combine two new high signal-to-noise ratio optical spectroscopic observations from the Hobby-Eberly Telescope with archival Hubble Space Telescope, Two Micron All Sky Survey, and Galaxy Evolutionary Explorer data to compute a bolometric luminosity from the accretion flow of L

New Roads to the Small-scale Universe: Measurements of the Clustering of Matter with the High-redshift UV Galaxy Luminosity Function
Authors: Sabti Nashwan , Muñoz Julian B. , Blas Diego 
Published: April 2022

Abstract
The epochs of cosmic dawn and reionization present promising avenues for understanding the role of dark matter (DM) in our cosmos. The first galaxies that populated the universe during these eras resided in DM halos that were much less massive than their counterparts today. Consequently, observations of such galaxies can provide us with a handle on the clustering of DM in an otherwise currently inaccessible regime. In this work, we use high-redshift UV galaxy luminosity function (UV LF) data from the Hubble Space Telescope to study the clustering properties of DM at small scales. In particular, we present new measurements of the matter power spectrum at wavenumbers 0.5 Mpc−1 < k < 10 Mpc−1 to roughly 30% precision, obtained after marginalizing over the unknown astrophysics. These new data points cover the uncharted redshift range 4 ≤ z ≤ 10 and encompass scales beyond those probed by cosmic microwave background and large-scale structure observations. This work establishes the UV LF as a powerful tool to probe the nature of DM in a different regime than other cosmological and astrophysical data sets.
Introducing MEGASIM: Multitudinous Earth Greek/Trojan Asteroid SIMulation*
Authors: Yeager Travis , Golovich Nathan 
Published: April 2022

Abstract
We announce the completion of two new Earth Trojan Asteroid (ETA) simulations. ETAs co-orbit the Sun with Earth and remain loosely bound to the fourth or fifth Lagrange points. To date, two ETAs have been detected (2010 TK7 and 2020 XL5); however, based on their orbits, these are likely temporary captures rather than members of a primordial population. The motivation for our simulations is multi-faceted: (1) the lack of a detected population despite literature claims of stability over the age of the solar system, (2) ETAs are important for both solar system science and planetary defense, and (3) the proximity of ETAs makes them prime candidates for space exploration missions. These simulations are of extremely high fidelity, large in number and long in simulation time. We will be releasing a series of papers based upon these simulations.

Resistencia al desgaste y rendimiento durante procesos de extrusión a escala industrial de los aceros 100Cr6 y 21NiCrMo2 sometidos a tratamientos criogénicos
Authors: Karaca Bahadır , Cenk Kumruoğlu Levent 
Published: April 2022

Se ha investigado los efectos de diferentes parámetros de tratamiento térmico y criogénico como la temperatura y el tiempo de mantenimiento sobre la microestructura (cantidad de austenita retenida) y la dureza de moldes de extrusión producidos a partir de los aceros 21NiCrMo2 y 100Cr6. La matriz de extrusión del acero 21NiCrMo2 se cementó durante 22,5 h en una atmósfera de gas (25% CO, 35% N2, 40% H2) a 920 °C. Al final del proceso de cementación, la temperatura se mantuvo a 850 °C, que es la temperatura de austenización, durante 2 h, seguido de enfriamiento en aceite a 80 °C, permaneciendo en aceite durante 45 minutos. No se realizó este proceso de cementación para los moldes de extrusión fabricados con el acero 100Cr6. En este acero solo se llevó a cabo el tratamiento de austenización a la temperatura de 850 °C (manteniendo durante 2 h). Los moldes de acero que se fabricaron con aceros los 21NiCrMo2 y 100Cr6 se trataron posteriormente de manera criogénica a -120 °C durante 2 h y, posteriormente, se templaron a 150 °C durante 1,5 h. Como resultado del tratamiento criogénico, la dureza del acero 21NiCrMo2 aumentó hasta los 840 Hv y mejoró la resistencia al desgaste de la superficie de la matriz de extrusión. La cantidad de austenita residual disminuyó del 20% al 6% después del tratamiento criogénico. Por efecto del proceso criogénico, la dureza superficial de la muestra de acero 100Cr6 aumentó a ~870 Hv, lo que supone un incremento del 4,5%, debido a la transformación de la austenita residual a martensita. La pérdida de masa durante el ensayo de desgaste de las matrices de extrusión endurecidas se redujo de 0,1420 mg a 0,0221 mg. El valor de resistencia al impacto medido en esta condición fue de 20 J. El acero 100Cr6 después del tratamiento criogénico se usó para extruir 12 toneladas de aleación de Al en una prensa industrial. Esta cantidad de material es un 30% inferior a la del acero para herramientas para trabajo en caliente. Por otro lado, el acero 100Cr6 es más económico y el tratamiento térmico es más práctico. El rendimiento durante el proceso de extrusión del acero 21NiCrMo2 fue un 50% inferior al del acero para herramientas de trabajo en caliente.

Published: April 2022

Context
Athletic training is a multifaceted profession characterized by interpersonal relationships and a team approach to care. Collaborative relationships, by nature, open the door to conflict, which has been reported frequently in the collegiate athletic setting. However, secondary school athletic trainers' (ATs') experiences with conflict and pressure in their role are not readily understood.

Objective
To measure the extent and sources of stress, pressure, and conflict within the secondary school athletic training setting and determine if differences exist across employment characteristics.

Design
Cross-sectional study.

Setting
Secondary school athletics.

Patients or Other Participants
Secondary school ATs (n = 725, age = 39.8 ± 10.5 years, years certified = 16.7 ± 9.7, years in current role = 10.6 ± 7.8).

Main Outcome Measures
Participants were asked to reply to an online questionnaire with quantitative measures pertaining to organizational conflict and workplace dynamic. Employment type (school district employee, school district teacher, medical or university facility, independent contractor) and status (full time, part time) served as independent variables. Likert-scale scores (1 = strongly agree to 5 = strongly disagree; 1 = always to 5 = never) and perceived sources of stress, pressure, and conflict were the dependent variables. Analyses consisted of Kruskal-Wallis tests with Mann-Whitney U post hoc tests and odds ratios to assess associations between variables of interest.

Results
We obtained a 15.3% response rate (725/4745). Although the ATs reported experiencing conflict and pressure, these experiences were relatively infrequent and not universal. Compared with part-time ATs, full-time ATs described higher ratings of strong relationships with coaches (P = .003) and principals (P = .002). The most frequently identified sources of conflict were parents (59%) and coaches (53.9%), followed by athletes (32.6%). Full-time ATs were 1.6 times more likely to report experiencing conflict with a coach than part-time ATs (odds ratio = 1.550, 95% CI = 1.037, 2.317; P = .040).

Conclusions
Secondary school ATs' experiences regarding organizational conflict were relatively positive. Instances of pressure and conflict were noted, though relatively infrequently, and these experiences were largely uninfluenced by employment type.
Role of anti-phospholipase A2 Receptor antibodies in patients with membranous nephropathy
Authors: Karimkhan Afreen , Kini Usha , Shenoy Pradeep M. , Satish Renuka , Puttegowda Divya 
Published: April 2022

Context:
A search for a cause for membranous nephropathy (MN) is crucial to determine its treatment and management. Primary MN was a diagnosis of exclusion until the discovery of the target antigen, phospholipase A2 receptor (PLA2R). Lack of published data from the Indian population prompted this prospective study to determine the sensitivity and specificity of circulating anti-PLA2R antibodies in MN patients by using cell-based indirect immunofluorescence test (IIFT) and correlating with clinical–histopathology features and response to treatment.

Settings and Design:
This was a cross-sectional prospective study.

Materials and Methods:
MN cases (n = 34) diagnosed by renal biopsy and IIFT were evaluated along with 10 controls for serum anti-PLA2R antibodies using IIFT on biochip containing HEK 293 cell lines transfected with cDNA coded for PLA2R in this cross-sectional prospective study and simultaneously investigated to find the cause for MN. Positive cases treated with the Ponticelli regimen were followed up for 6 months with repeat testing for PLA2R. Statistics were performed using Statistical Package for Social Sciences version 18 (IBM).P< 0.05 considered significant. Statistical parameters were analyzed using the Chi-square test.

Results:
Anti-PLA2R antibodies-positive MN (primary MN) cases (n = 20) had higher 24-h proteinuria (10.09 ± 2.46 g) with 25% cases showing mesangial hypercellularity and basement membrane thickening in all (100%), while 50% of secondary MN cases showed mesangial hypercellularity with 7.17 ± 3.8 g of proteinuria. The sensitivity, specificity, and accuracy rate of anti-PLA2R antibodies for a diagnosis of primary MN were 70%, 100%, and 82%, respectively.

Conclusion:
Anti-PLA2R antibody in serum is a good reliable noninvasive diagnostic biomarker for primary MN and for monitoring its disease activity.
