Distinct perivillious fibrin deposition and evidence of persisting positive SARS-CoV-2 PCR in placental tissue after COVID-19 Infection in the second trimester
Authors: Beda Hartmann , Lisa Rindler , Selma Hoenigschnabl 
Published: September 2022

Background: The effects of Coronavirus disease 2019 in women during the second trimester of pregnancy and the health of the fetus, remain very poorly explored. This report describes a case in which the normal development of pregnancy was complicated immediately after the patient had experienced COVID-19 at the 21st week of gestation. Specific conditions included critical blood flow in the fetal umbilical artery, fetal growth restriction and hydramnios in the 25th week of gestation. After informed consent, we decided just to wait and interrupted all examinations (CTG, Ultrasound) because of the high risk of severe adverse events at such an early premature birth. The patient finally delivered a healthy boy in the 39th week of gestation.	Methods: We performed a histological examination of the placenta and analyzed the placenta for the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) through molecular and immunohistochemical assays and measured the fetal antibody response in the blood to this infection. Results: In the immunohistochemical examination with antibodies against SARS-CoV-2 a partial positivity in the villious throphoblastic epithel cells could be demonstrated. The PCR swab of the placenta which was obtained was positive for SARS-CoV-2 with a crossing threshold value of 22,8. The histological examination of the placenta showed a Massive Perivillous Fibrinoid Deposition (MPFD) with multiple focal placental infarctions in the intervillious space, intervillious thrombus, and a localized chorangiomatosis. Conclusion: According to many clinical and laboratory findings in this patient, the histopathological features and viral infection of the placenta suggest a prominent role for COVID-19 in this patient’s presentation. This is highlighted by the presence of levels of SARS-CoV-2 RNA. In this patient, an infection with Sars-CoV-2 might have caused the development of the MPFD. These findings suggest that COVID-19 may have contributed to placental dysfunction and fetal growth retardation. Also with a SARS-CoV-2 PCR test with a crossing threshold value of 22,8, it must be assumed that the placenta has been potentially infectious.
Restoring a near anatomical hip joint in an 18 year old neglected hip fracture dislocation – A rare case report
Authors: Mukherjee Kaustav , Raja Dorai Kumar 
Published: September 2022

Long standing neglected traumatic hip fracture dislocation is a rare clinical condition. Obliteration of the native acetabulum, soft tissue contractures, loss of femoral head congruity and associated hip fractures make this condition challenging to treat. We discuss a case of a middle-aged male presenting to us with pain, shortening and inability to bear weight on left lower limb for last 15 years. Clinical examination revealed an adduction deformity over the left hip, a globular swelling in the left gluteal region and a fixed equinus deformity over left ankle. Movements at the left hip hinted at restricted internal rotation and flexion. Pelvis radiographs revealed a neglected posterior hip dislocation with ipsilateral femur neck non union. Patient underwent initial upper tibial traction for 8 weeks followed by a hybrid Total Hip Arthroplasty. Postoperatively intensive physiotherapy was continued and with correction of the ankle equinus patient was able to ambulate. On five years follow-up, the patient was mobilizing independently, pain-free with a mild short limb gait and some residual foot drop.Treatment of neglected hip fracture dislocation can be challenging. Associated economic restraints may hinder clinicians from higher imaging and make the treatment even difficult. However, an anatomical reconstruction of hip by a total hip arthroplasty has yielded good functional outcomes in long standing neglected dislocations.’

Cephalometric evaluation of pharyngeal airway space after orthodontic extraction treatment in adult patients with Class II malocclusion: an integration with subjective sleep quality assessment
Authors: Vejwarakul Weerayuth , Ko Ellen Wen-Ching , Lin Cheng-Hui 
Published: September 2022

Abstract
Objectives
This study (1) compared the changes in regional pharyngeal airway space (PAS) after orthodontic treatment among 3 groups of adult patients with Class II malocclusion and (2) identified correlations between questionnaire results and PAS dimensions after orthodontic treatment.
Materials and methods
In this retrospective cohort study, 79 consecutive patients were divided into normodivergent nonextraction, normodivergent extraction, and hyperdivergent extraction groups. Serial lateral cephalograms were used to evaluate the patients’ PASs and hyoid bone positions. The Pittsburgh Sleep Quality Index and STOP-Bang questionnaire were used for sleep quality evaluation and obstructive sleep apnea (OSA) risk assessment, respectively, after treatment.
Results
The greatest airway reduction was observed in hyperdivergent extraction group. However, the changes in PAS and hyoid positions did not differ significantly among 3 groups. The PAS behind the soft palate and tongue was determined to be susceptible to reduction. According to questionnaire results, all 3 groups had high sleep quality and low risk of OSA, with no significant intergroup differences. Moreover, pretreatment-to-posttreatment changes in PAS were not correlated with sleep quality or risk of OSA.
Conclusions
Orthodontic extraction and incisor retraction do not affect the dimensions of pharyngeal airway. Vertical control of Class II skeletal malocclusion, especially in cases involving retrusive chins, can be applied to prevent the worsening of facial profile and to mitigate a tendency of reduction of airway dimensions.
Clinical relevance
Orthodontic treatment with premolar extractions does not exhibit a reduction in airway dimensions or diminish the patients’ sleep quality or increase their risk of OSA.

Abstract
Cellular senescence is a state of permanent growth arrest that plays an important role in wound healing, tissue fibrosis, and tumor suppression. Despite senescent cells’ (SnC) pathological role and therapeutic interest, their phenotype in vivo remains poorly defined. Here, we developed an in vivoderived senescence signature using a foreign body response (FBR) fibrosis model in a SnC reporter mouse. We identified pericytes and “cartilage-like” fibroblasts as senescent and defined cell typespecific senescence associated secretory phenotypes (SASP). Transfer learning and senescence scoring identified these two SnC populations along with endothelial and epithelial SnCs in new and publicly available murine and human data single cell RNAseq (scRNAseq) datasets from diverse pathologies. Signaling analysis uncovered crosstalk between SnCs and myeloid cells via an IL34- CSF1R-TGFßR signaling axis, contributing to tissue balance of vascularization and matrix production. Overall, our study provides a senescence signature and a computational approach that may be broadly applied to identify transcriptional profiles and SASP factors produced by SnCs that regulate tissue structure and pathology.

Abstract
Charcot’s triad, consisting of high fever, abdominal pain, and jaundice, is a well-known clinical feature of acute cholangitis. However, some patients, especially elderly patients, are asymptomatic. We reported herein a case of acute cholangitis in an elderly patient on hemodialysis who was asymptomatic, but whose cholangitis was discovered when a yellow discoloration of her dialyzer was noticed. Blood tests and imaging studies should be performed as soon as possible after noticing yellowish discoloration of dialyzer fibers because asymptomatic acute cholangitis may be present.
CO2 degassing in the mantle triggers deep earthquakes at the Mid-Atlantic Ridge

Published: September 2022

Abstract
Oceanic crust is formed by melt derived from the mantle at oceanic spreading centers. A small amount of melting initiates at about 150-300 km depths in the presence of volatiles (CO2, H2O)1–3, but the extensive dry melting commences at 60-70 km depths due to the upwelling of the mantle as two diverging plates move apart4,5. However, how these melts migrate to the surface and what happens to these melts in the upper part of the mantle are still not understood. Using seismological data recorded by ocean-bottom seismometers, here we report the presence of deep earthquakes at 10-20 km depth in the hot mantle along the Mid-Atlantic Ridge axis, much below the brittle-ductile boundary, suggesting that these earthquakes are caused by a volume change associated with the CO2 degassing from the ascending melt. The geochemical analyses of basalts from the ridge axis show an abnormally high quantity of CO2 (>1.9 wt%) in the primitive melt, confirming the CO2 degassing hypothesis. The large concentration of CO2 in the primitive melt will influence the presence of melt beneath the lithosphere-asthenosphere boundary at sub-solidus temperatures.

Abstract
To harness the intriguing properties of two-dimensional van der Waals (vdW) ferromagnets (FMs) for versatile applications, the key challenge lies in the reliable material synthesis for scalable device production. Here, we demonstrate the epitaxial growth of single-crystalline 1T-CrTe2 thin films on 2-inch sapphire substrates. Benefiting from the uniform surface energy of the dangling bond-free Al2O3(0001) surface, the layer-by-layer vdW growth mode is observed right from the initial growth stage, which warrants precise control of the sample thickness and atomically smooth surface morphology across the entire wafer. Moreover, the presence of the Coulomb interaction at the CrTe2/Al2O3 interface serves as an effective tuning parameter to tailor the anomalous Hall response, and the structural optimization of the CrTe2-based spin-orbit torque device leads to a substantial switching power reduction by 54%. Our results may lay out a general framework for the design of energy-efficient spintronics based on configurable vdW FMs.

Abstract

We have analyzed effects of compound events on heat-related health risks by vulnerable groups in Seoul Metropolitan Area, South Korea from 2012 to 2020. A multivariate analysis was conducted for heat-related health impacts by combination of meteorological factors. We have found that heat-related health risks have increased by compound events effects by humidity and solar radiation. Heat-related patients occurred more frequently in higher humidity or intense solar radiation conditions than in usual conditions. All-cause mortalities were higher with high vapor pressure (6.4%, 95% CI: 4.5–8.4%) and large amount of solar radiation (7.5%, 95% CI: 5.2–9.7%) conditions. Infectious and metabolic mortalities have increased about 10% in higher humidity or intense solar radiation conditions. The effects of compound events were different by vulnerable groups. Female’s metabolic mortalities were higher (24.3%, 95% CI: 11.2–37.5%) with solar radiation. The circulatory mortalities of outdoor workers (10.1%, 95% CI: -5.6–25.7%), daytime occurrence (12.5%, 95% CI: 7.6–17.4%), and lower education (13.9%, 95% CI: 7.6–20.1%) has also increased by solar radiation. Mortality of infectious diseases has increased in elderlies (23.5%, 95% CI: 10.3–36.7%) by duration of sunshine. It shows heat waves warnings and policies should consider other meteorological factors other than temperature.

Abstract
In order to make the carbon footprint minimum, All the countries around the world are trying to increase the penetration of renewable energy in their grids. But during the faults, The microgrids suffer from forced islanding. It is therefore required to enhance the fault ride-through capability of the microgrids, whether DC, AC or Hybrid Microgrids. This will augment their power quality and also support the grids from fault recovery by supplying enough reactive and real power into the grid within 150 ms. ESS will have a hybrid structure in future comprising of batteries, ultra capacitors, fuel cells, flywheels. In this paper,

Abstract
The optimal conditions for the green synthesis of nano zero-valent iron (G-NZVI) using mango peel extract were investigated using a Box-Behnken Design approach. Three factors were considered, including the ratio of iron solution to mango peel extract ratio (1:1–1:3), feeding rate of mango peel extract (1–5 mL/min), and agitation speed (300–350 rpm). The results showed that the optimal conditions for the synthesis of G-NZVI for arsenate removal were a 1:1 ratio of iron solution to mango peel extract, a mango peel extract feeding rate of 5 mL/min, and an agitation speed of 300 rpm. Under these conditions, nearly 100% arsenate removal was achieved. X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), Transmission Electron Microscopy (TEM), Brunauer-Emmett-Teller (BET), and Scanning Electron Microscopy (SEM) with Energy Dispersive X-Ray Analysis (EDX)methods were used to characterize the properties of the G-NZVI. Finally, the arsenate removal efficiency of the G-NZVI was compared against commercial nano zero-valent iron (C-NZVI). The results revealed that the G-NZVI was roughly five times more efficient at arsenate removal than the C-NZVI. The influence of background species such as chloride (Cl−), phosphate (PO43−), calcium (Ca2+), and sulfate (SO42−) was studied to evaluate their effects on arsenite removal. As a result, Cl− and Ca2+ were shown to play a role in promoting arsenite removal, whereas SO42− and PO43− were observed to play an inhibiting role.

Abstract

Background There is growing interest on how social capital and related social environmental factors impact overall population health and well-being. The nature of migrants’ social environment changes once they migrate to a new context and these changes influence their mental health and well-being. However, there is limited scholarship on how these social environmental factors impact the mental health, well-being, and capacity to flourish of migrant populations. Methods The aim of the study, therefore, was to examine how specific social environmental factors—social networks, social support, and social cohesion at various levels (micro, meso, and macro)—influence the mental health, well-being, and capacity to flourish of migrants in France. We used a qualitative, inductive research design, in collaboration with a community-based organization,Habitat et Humanisme,to conduct 120 semi-structured interviews with migrants and asylum seekers in France. Results Participants described how their usual informal social networks comprised of family and friends had been disrupted since they migrated to France, which impacted their mental health and well-being. Conversely, staying connected with their informal transnational social networks via social media and developing ties with new local informal and formal social networks allowed them to receive different forms of social support, and buffered some of the negative mental health effects. However, the lack of social cohesion impeded migrants’ capacity to flourish. The emerging salient themes depicting a lack of social cohesion included a lack of belonging and marginalization, uprootedness and uncertainty, a lack of identity and security, and current harmful migration-related policies. Conclusion While social support derived from social networks buffered some negative impacts on migrant mental health and well-being, the overall lack of social cohesion ultimately impeded migrants’ capacity to flourish within their host communities, which was further exacerbated by harmful migration policies of exclusion within France. Introducing more inclusive policies related to the governance of migration and an intersectoral approach that views health in all policies is key to promoting social cohesion and flourishing among migrants in France.
Design and implementation of an efficient multilayer, Multibit Barrel-Shifter using QCA with reversibility and stability
Authors: Sarkar Swarup , Roy Rupsa 
Published: September 2022

Abstract
In the present digital Nano-electronic era, the Quantum cell-based QCA (“Quantum-dot cellular automata”) technical platform is a suitable alternative to the transistor-level-based C.MOS-Technologies (Complementary metal oxide semiconductor technology).In this paper, the QCA technology is used to design multilayer, 3D, multi-bit (up to 8bit is selected) quantum low powered, high speed, optimum cost-effective Barrel Shifter. In the proposed Barrel-Shifter design, the reversibility is properly checked by using 2:1 MUX, and response analysis is also discussed appropriately. Along with this, the presented structures in this paper are compared with existing advanced related works and these comparisons are mainly based on an occupied unit area, area-based power consumption, latency, complexity, and cost. Additionally, the stability checking of the proposed multilayer Barrel-Shifter structure (in terms of output-polarization) is also included in this work based on the temperature tolerance and layer separation gap.
Influence of deformed cavity field and atomic dipole interaction on the quantum correlations of two-qubit system
Authors: Ali S. I. 
Published: September 2022

Abstract
The possibility of generating of some quantum correlations of entangled or separable initial two-qubit system interacts with a deformed cavity mode on the presence of dipole-dipole interaction is discussed. These quantum correlations are the coherence, non-separability, and steering degrees, which are quantifiers by using l1 norm of coherence, Entanglement of Formation (EoF), and Einstein-Podolsky-Rosen (EPR)-steering. It is shown that, maximizing or minimizing the quantum correlations depend on the initial settings states of the two-qubit system. To maximize the quantum correlations on the presences of deformation, one has to prepare the initial two-qubit system in an entangled state, setting large values of the coupling dipole and decreasing the effect of deformation parameter.
