Published: April 2022

The IoT-based power monitoring device is a device composed of a CT sensor of type SCT-013, an AC-AC power adapter, an Arduino, and a Raspberry Pi. The tool is used to monitor voltage, current, frequency, real power, apparent power and power factor. The measured basic quantities are voltage, current, and frequency. The purpose of the measurement and monitoring processes is to conserve, control the quality, and control the use of electrical energy. In the measurement and monitoring process, tool accuracy is very important because it is closely related to the quality of electrical energy. This study presents an analysis of the accuracy of the power monitoring tool according to the variations in voltage, current, and frequency at the source. The method used is to vary the voltage, current and frequency used as input to the system and compare the measurement results of the power monitor with the Fluke True RMS Multimeter. The test results show that the level of accuracy of the IoT-based power monitoring device on the voltage parameter is 99.1%, the current parameter is 98.75%-99.25% and the frequency is 100%, so it is a proper tool to measure the quality of electrical energy.

Abstract
Efficient searches for electromagnetic counterparts to gravitational wave, high-energy neutrino, and gamma-ray burst events demand rapid processing of image arithmetic and geometry set operations in a database to cross-match galaxy catalogs, observation footprints, and all-sky images. Here we introduce HEALPix Alchemy, an open-source, pure Python implementation of a set of methods that enables rapid all-sky geometry calculations. HEALPix Alchemy is built upon HEALPix, a spatial indexing strategy that is widely used in astronomical databases as well as the native format of LIGO-Virgo-KAGRA gravitational-wave sky localization maps. Our approach leverages new multirange types built into the PostgreSQL 14 database engine. This enables fast all-sky queries against probabilistic multimessenger event localizations and telescope survey footprints. Questions such as “What are the galaxies contained within the 90% credible region of an event?” and “What is the rank-ordered list of the fields within an observing footprint with the highest probability of containing the event?” can be performed in less than a few seconds on commodity hardware using off-the-shelf cloud-managed database implementations without server-side database extensions. Common queries scale roughly linearly with the number of telescope pointings. As the number of fields grows into the hundreds or thousands, HEALPix Alchemy is orders of magnitude faster than other implementations. HEALPix Alchemy is now used as the spatial geometry engine within SkyPortal, which forms the basis of the Zwicky Transient Facility transient marshal, called Fritz.
WASP-35 and HAT-P-30/WASP-51: Reanalysis using TESS and Ground-based Transit Photometry
Authors: Bai Lu , Gu Shenghong , Wang Xiaobin , Sun Leilei , Kwok Chi-Tai , Hui Ho-Keung 
Published: April 2022

Abstract
High-precision transit observations provide excellent opportunities for characterizing the physical properties of exoplanetary systems. These physical properties supply many pieces of information for unvealing the internal structure, external atmosphere, and dynamical history of the planets. We present revised properties of the transiting systems WASP-35 and HAT-P-30/WASP-51 through analyzing newly available TESS photometry and ground-based observations obtained at the 1 m telescope of the Yunnan Observatories as well as from the literature. The improved system parameters are consistent with previous results. Furthermore, we find that the transits of HAT-P-30b/WASP-51b show possible timing variation that cannot be explained by a decaying orbit due to tidal dissipation and the Rømer effect, while both apsidal precession and an additional perturbing body could reproduce this signal according to our comprehensive dynamical simulations. Because both systems are valuable targets that are suitable for transmission spectroscopy, we make some predictions for the atmospheric properties of WASP-35b and HAT-P-30b/WASP-51b based on the newly derived system parameters.
Le syndrome de la couverture tirée comme risque de rupture de liens dans la clinique du placement familial
Authors: Vidal-Bernard Alexandra , Sanahuja Almudena 
Published: April 2022

Cette recherche s’intéresse aux problématiques de ruptures de liens dans la clinique du placement familial, notamment celles rattachées au conflit de loyauté pouvant être ressenti par des adolescents placés. Ce syndrome, qui peut être baptisé « syndrome de la couverture tirée », correspond à un phénomène de rivalité entre deux familles, une professionnelle et une biologique avec comme enjeu central l’adolescent. À partir d’une étude de cas paradigmatique menée dans le cadre de suivis thérapeutiques associés à une recherche exploratoire, les auteures, thérapeutes et chercheuses en psychologie clinique, procèdent à une analyse des phénomènes psychiques sous-jacents individuels et familiaux en s’appuyant sur les théories psychanalytiques groupales et familiales. Les résultats montrent que les ruptures de liens sont étroitement associées aux processus complexes d’affiliation et à l’empêchement du processus de séparation-individuation. Mais elles sont également liées à l’échec de la fonction tiers du service de placement.
Sortir de l’invisibilité : inégalités de genre dans les agricultures familiales en Afrique de l’Ouest
Authors: Droy Isabelle , Bidou Jean-Étienne 
Published: April 2022

En Afrique de l’Ouest, les agricultures familiales subissent des changements rapides, tant sous l’effet de la globalisation que des transformations sociodémographiques et environnementales. Ces bouleversements affectent la répartition des droits et des ressources au sein des unités familiales, en se traduisant fréquemment par un creusement des inégalités au détriment des femmes. Or, malgré de nombreux engagements politiques en faveur de la réduction des inégalités de genre, les méthodes mobilisées pour l’analyse des agricultures familiales et la mise en œuvre d’actions de développement restent souvent aveugles au genre, contribuant ainsi à la reproduction, voire à l’aggravation des inégalités.

Les opérations de relogement des quartiers insalubres à Casablanca : une logique contradictoire entre développement et inégalité
Authors: Samih Kawtar 
Published: April 2022

Programme phare de l’action publique marocaine depuis 2004, "Villes sans bidonvilles" vise à à la réduction des inégalités et à la lutte contre l’exclusion. À Casablanca, les quartiers insalubres et les opérations de relogement subissent les effets et les contre-effets de cette mise aux normes. Précaires et situés hors de la ville, les quartiers de relogement apparaissent destinés à redorer l’image internationale de Casablanca plutôt qu'à incarner une cohésion sociospatiale. Basé sur une série d’entretiens de populations, l’article examine cette expérience sociospatiale et en révèle les nouvelles pratiques. Classification JEL : E26, I31, J60, O17, O20

Authors: Fernández-Barrientos Yolanda , Ortega-Usobiaga Julio , Beltran-Sanz Jaime , Druchkiv Vasyl , Ramos-Navarro José Luis , González-de-Gor-Crooke José Luis 
Published: April 2022

PURPOSE:
To evaluate safety and efficacy in the management of flap displacement after laser in situ keratomileusis (LASIK) and subsequent complications.

METHODS:
This was a retrospective study performed using data recorded at the center's database from October 2002 to August 2021. Efficacy and safety were both converted to binary outcomes (loss of one or more lines and no change or gain in lines of visual acuity). The effects of time from surgery to complication and from complication to repair were assessed and the odds ratios and probabilities were calculated. The same procedure was applied to investigate the effect of these temporal variables on complications.

RESULTS:

A total of 66 eyes with late traumatic LASIK flap displacements were studied. Efficacy remained unchanged in 48 patients (64 eyes, 75%), and safety remained unchanged in 53 patients (59 eyes, 90%). Sixty-six patients (64 eyes, 100%) achieved visual acuity values of 20/40 and 45 patients (64 eyes, 70.3%) achieved values of 20/20. The flap displacement was resolved in the first 24 hours (SD ± 0.1 days). Surgery was performed in 58 patients (65 eyes, 90%). Epithelial ingrowth was the most frequent complication. Patients who underwent surgery tended not to lose lines (
P
= .05). The risk of developing epithelial ingrowth increases with time after LASIK surgery until traumatic flap displacement (odds ratio: 1.001;
P
< .001). The prevalence of dislocation during the study period was 0.012%.

CONCLUSIONS:
Visual safety values were favorable after resolution of the flap complication. Immediate surgical management leads to better visual efficacy, and the time between LASIK and trauma increases the risk of epithelial ingrowth after flap displacement.

Authors: Sozzi Fabiola B. , Iacuzio Laura , Belmonte Marta , Schiavone Marco , Bursi Francesca , Gherbesi Elisa , Levy Frank , Canetta Ciro , Carugo Stefano 
Published: April 2022

Cardiomyopathies (CMPs) are diseases of the heart muscle. They include a variety of myocardial disorders that manifest with various structural and functional phenotypes and are frequently genetic. Myocardial disease caused by known cardiovascular causes (such as hypertension, ischemic heart disease, or valvular disease) should be distinguished from CMPs for classification and management purposes. Identification of various CMP phenotypes relies primarily upon echocardiographic evaluation. In selected cases, cardiac magnetic resonance imaging (CMR) or computed tomography may be useful to identify and localize fatty infiltration, inflammation, scar/fibrosis, focal hypertrophy, and better visualize the left ventricular apex and right ventricle. CMR imaging has emerged as a comprehensive tool for the diagnosis and follow-up of patients with CMPs. The accuracy and reproducibility in evaluating cardiac structures, the unique ability of non-invasive tissue characterization and the lack of ionizing radiation, make CMR very attractive as a potential “all-in-one technique”. Indeed, it provides valuable data to confirm or establish the diagnosis, screen subclinical cases, identify aetiology, establish the prognosis. Additionally, it provides information for setting a risk stratification (based on evaluation of proved independent prognostic factors as ejection fraction, end-systolic-volume, myocardial fibrosis) and follow-up. Last, it helps to monitor the response to the therapy. In this review, the pivotal role of CMR in the comprehensive evaluation of patients with CMP is discussed, highlighting the key features guiding differential diagnosis and the assessment of prognosis.
Investigation of the relationship between miR-33a, miR-122, erythrocyte membrane fatty acids profile, and serum lipids with components of metabolic syndrome in type 2 diabetic patients
Authors: Masoudi Fatemeh , Sharifi Mohammad Reza , Pourfarzam Morteza 
Published: April 2022

Background and purpose:
MicroRNAs (miRNAs) are small non-coding RNA molecules acting as critical regulators of post-transcriptional gene expression. MiR-33a and miR-122 have a crucial role in cholesterol and lipid metabolism. Therefore, their dysregulation may contribute to metabolic abnormality and their inhibition may be a useful therapeutic strategy. The objective of the present study was to investigate the relationship between miR-33a, miR-122, erythrocyte membrane fatty acids profile, and serum lipids with components of metabolic syndrome in an Iranian population suffering from type 2 diabetes mellitus (T2DM).

Experimental approach:
Expression of miR-33a and miR-122 was measured by real-time polymerase chain reaction and erythrocyte membrane fatty acid profiles were analyzed by gas chromatography-mass spectrometry.

Findings/Results:
T2DM patients with and without metabolic syndrome had significantly higher miR-33a and miR-122 levels compared to controls. MiRNAs were significantly correlated with saturated fatty acid (SFAs), total SFAs/total polyunsaturated fatty acids (PUFAs) ratio, fasting plasma glucose, triacylglycerols, insulin and homeostatic model assessment of insulin resistance. In addition, there was a significant negative correlation between miR-33a and miR-122 levels and PUFAs, total PUFAs/total SFAs ratio and omega 6 fatty acids.

Conclusion and implications:
Considering the roles of miR-33a and miR-122 in cholesterol and lipids metabolism, it may be concluded that the measurement of their expression may be useful as a potential additional biomarker for cardiometabolic derangement in T2DM patients. In addition, these findings may suggest that the inhibition of these miRNAs by anti-miRNA therapies may be explored as a potential therapeutic strategy.
Design and production of a novel chimeric human growth hormone superagonist fused to human Fc domain
Authors: Mirbaha Samira , Rezaei Marzieh , Emamzadeh Rahman , Zarkesh Esfahani Sayyed Hamid 
Published: April 2022

Background and purpose:
Growth hormone (GH) has been known as a crucial metabolic hormone expressed at the pituitary and the other number of cells and tissues and responsible for body growth. Because of the short half-life of GH, daily subcutaneous injections were shown to be more effective for GH therapy. This represents a burden for patients. So, there is a strong effort from the industry to create a long-acting form of GH and lots of technologies like GH fusion proteins are used to increase GH half-life.

Experimental approach:
In this study, the Fc domain of human IgG1 with serine-glycine linkers was attached to the C-terminal of a GH superagonist via molecular cloning. The presence of recombinant vector in E. coli host was confirmed by PCR. SDS-PAGE and western blot analysis showed the expression of recombinant proteins in the bacterial lysate. The binding ability to growth hormone receptors is determined by ELISA.

Findings / Results:
Our results showed that the novel SupGH-Fc has a good binding affinity to its receptor in ELISA in comparison to standard GH, although it has a big size.

Conclusion and implications:
Our data in this study clearly demonstrated the expression of the SupGH-Fc in a recombinant protein expression system. It is an introduction to the production of the new recombinant GH, which can bind to its receptor more effectively than commercial growth hormones and also might have a longer half-life.
Association of Hemoglobin Levels with Symptoms of Premenstrual Syndrome in Adults
Authors: Mamatha S. D. , Priya S. A. , Smitha M. C. 
Published: April 2022

ABSTRACT

Background:
Most women of reproductive age experience physical, emotional, and psychological discomfort in the week before menstruation called premenstrual syndrome (PMS). However, the specific cause for PMS is still not clear. In this study, we aimed at assessing the association of hemoglobin (Hb) level with PMS symptoms.

Materials and Methods:
One hundred and forty-nine healthy female students from medical and paramedical courses of age 18–22 years who were not on any medications were included in the study. The Hb of each participant was measured. A structured PMS symptoms questionnaire was designed based on the article by Lori M. Dickerson et al. The participants were asked to fill the questionnaire and scoring was done. Data were analyzed in SPSS V24. Descriptive statistics were used to calculate proportions and inferential statistics such as the unpaired t-test and one-way analysis of variance was used to compare the Hb level among those with PMS and those without and the association of Hb level with the type of PMS symptoms, respectively.

Results:
58.4% had PMS. There was a significant association of Hb level with PMS and lower Hb level was associated with physical and emotional symptoms.

Conclusion:
Occurrence of PMS symptoms was proportional to a fall in Hb level. Most physical symptoms of PMS are similar to anemia, hence can be confused due to PMS. Therefore, Hb level estimation helps in preventing misdiagnosis of PMS or symptoms related to decreased Hb level and also symptoms can be reduced by improving Hb levels.

Authors: Morgan Kerri , Heeb Rachel , Walker Kim , Tucker Sue , Hollingsworth Holly 
Published: April 2022

Background
Emerging evidence suggests that the COVID-19 pandemic has been accompanied by increased rates of depression and social isolation. However, we do not yet understand how the COVID-19 pandemic has affected the psychosocial health of people with spinal cord injury (PwSCI), a population that is already at risk of experiencing mental health conditions.

Objectives
The aims of the study were to (1) examine the impact of the pandemic on the psychosocial health of PwSCI and (2) investigate the experiences of PwSCI and resources they reported needing during the peak of the pandemic.

Methods
A cross-sectional survey with closed- and open-ended questions was administered to 51 PwSCI. Participants were included if they had an SCI, were 18 years or older, lived in St. Louis, Missouri, and surrounding areas, and understood English.

Results
Canonical correlation showed a significant association between financial security, food insecurity, and personal assistance service use and adverse psychosocial health outcomes (p &lt; .001). Participants reported interest in resources related to COVID-19 precautions for wheelchair users as well as home exercise programming and financial assistance with utilities. Finally, qualitative analysis revealed four major themes: (1) mental health during the pandemic, (2) financial concerns and reduced access to personal assistance services, (3) feelings of social isolation prior to the pandemic, and (4) local and national authorities’ handling of the pandemic.

Conclusion
PwSCI are impacted by the COVID-19 pandemic and reported a variety of resource needs. These findings may inform service providers, support systems, and organizations to better support PwSCI during times of crisis.
