Published: February 2022

Abstract
The objective of this study was to compare the transformation of by-products between single dielectric barrier discharge (SDBD) and double dielectric barrier discharge (DDBD), to optimize the preparation of graphene-based catalysts and apply them in combination with DBD for VOCs degradation. The effect of three experimental conditions (initial concentration, output voltage, flow rate) on degradation rate, by-product transformation, and mineralization was investigated comparatively for SDBD and DDBD. Graphene oxide was prepared using the improved Hummers' method, and the optimal pathway of adding KMnO4 was selected. Graphene-based catalysts were synthesized using the ion-assisted hydrothermal method. The effect of the amount of 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM]PF6) on the preparation of three typical transition metal catalysts (Mn, Fe, and Ti) was studied. It was found that NO2 transformation rate of DDBD was higher than that of SDBD. The addition amount and interval time of KMnO4 affect the preparation of graphene oxide. [BMIM]PF6 dose of 0.25 ml, the preparation of three catalysts showed the best performance. MnOx/rGO exhibited superior performance in the degradation of benzene series, NO transformation, NO2 transformation, CO2 selectivity, and energy efficiency. FeOx/rGO exhibited superior performance for O3 transformation. Mn3O4 and Fe3O4 played a leading role in promoting the degradation of the benzene series and the transformation of by-products.

Abstract
Pyogenic spondylodiscitis (PS) frequently occurs in the elderly or those with risk factors, such as diabetes mellitus (DM), chronic renal disease (CRD), and malignancy. Although we have recorded PS occurring in patients with atopic dermatitis (AD), there have been no reports on the same. This retrospective study aimed to determine whether AD is a potential risk factor for PS. We reviewed the clinical records of 39 patients with PS who were surgically treated. Causative bacteria were identified via blood and operative tissue samples and compared to the underlying diseases and age at onset, for patients with AD, DM, CRD, and malignancy. Consequently, AD was identified as the underlying disease in five patients (12.8%); DM, in 12 (30.8%); CRD, in nine (23.1%); and malignancy, in five (12.8%). Staphylococcus aureus was identified as the causative bacteria for all patients in AD (100%), five in DM (41.7%), two in CRD (22.2%), and one in malignancy (20.0%). Age at onset was significantly lower in AD as compared to the other three groups. In this study, the onset of PS in all patients with AD was 50 years, caused by S. aureus. These results suggest that AD is risk factor for middle-aged patients with PS.

Abstract
Recently, Northwest China has been suffered PM2.5 pollution. Through a case study of Lanzhou city, capital of Northwest China’s Gansu province, a hyperchaotic cuckoo search-extreme learning machine (HCCS-ELM) approach is proposed to establish a PM2.5 concentration prediction model. The cuckoo search is used to generate the number of hid- den layer neurons in ELM. The hyperchaotic system is innovatively introduced to improve the accuracy of the algorithm with its good ran- domness and convergence. HCCS-ELM has a similar memory footprint as ELM, while experiments using observed data from four monitoring stations in Lanzhou during 2016 to 2018 show that HCCS-ELM has higher accuracy in PM2.5 hourly and daily concentration prediction.
Challenges To Maintaining Disaster Relief Supply Chains In Island Communities: Disaster Preparedness And Response In Honolulu, Hawai’i
Authors: Shen Suwan , Chang Ray Hsienho , Kim Karl , Julian Megan 
Published: February 2022

Abstract
Due to global warming and rising sea levels, Honolulu, Hawai’i—a city on a remote island in the Pacific Ocean—is becoming more vulnerable to climate disasters. This article utilizes a mixed-method approach to investigate the challenges of maintaining disaster relief supply chains in the face of the emerging risks to Honolulu. We conduct eighteen in-depth interviews with key emergency management stakeholders to understand current approaches to supply chain risk management. Based on the research, three main challenges influence disaster preparedness in Hawai’i. First, the physical location of the island and the spatial distribution of risk, assets, and capabilities supporting emergency relief present large, unusual constraints not found in other jurisdictions. Second, the challenges of supply chain management, planning, communications and coordination are exacerbated during disruptions and disaster events. Unlike other states, with neighboring, contiguous jurisdictions, there are severe limitations to mutual aid and assistance from outside sources. Third, our research has also identified cultural challenges associated with social, political, and economic development and change. Stronger institutional collaboration both within the state and beyond its boundaries are key to increased supply chain resilience and effective response and recovery from disasters. We conduct social network analysis focusing on measures of density, degree, betweenness, and centrality to better understand the status and gaps in institutional collaboration. The social network analysis reveals that the current levels of collaboration are relatively low with significant gaps between government agencies and the private sector, as well as limited vertical collaborations with respect to supply chain management between federal, state and local partners. There is a need for stronger leadership with deeper engagement across stakeholders. A pathway forward includes: 1) vulnerability analyses focused on private sector supply chain management and public sector transport hubs, networks, and facilities, 2) exercises and training on emergency supply chain management, and 3) longer-term actions to support sustainability, self-sufficiency, local production, and community resilience. Our research is relevant not just to Hawai`i and other island and isolated communities but also to communities threatened by supply chain disruptions.

Abstract
Background: SARS-CoV-2 virus is the cause of the global pandemic since the end of the year 2019. Since then, the virus has had mutations that cause different types of variants with various effects on those infected. This has complicated human intervention for prevention. Indonesia is one of the countries which was heavily affected by the pandemic specifically from May to August 2021, and it is a country that has recorded many distinct isolates.Methods: GISAID database was used to obtain the Indonesian isolates while NCBI BLAST was utilized for comparison of all variants, and MAFFT version 7 for multi comparison.Results: There were 9,488 isolates in Indonesia as of November 2021 where most include the Delta variant. Most of the isolates have mutations common to the ones from other countries. Although there are some atypical ones such as the mutation V1264L in the Delta variant that was suspected play a role in worsening the pandemic.Conclusions: The Delta variant had the most mutations in the Spike protein, when compared to the Alpha and Beta variants, giving its important roles in infectivity and vigorous entry into cells, explaining why in the period of May to November 2021 in Indonesia, there was a rocket of cases for the Delta variant unlike the other variants

Abstract
Background: This study aimed to investigate the short-term effectiveness of scapular focused taping (SFT) on scapular position and kinematics during the tennis serve among professional players with and without shoulder pain. Methods: The cohort included 7 players who had no history of shoulder pain (NSP) and 6 players with shoulder pain (SP). All participants performed tennis flat serves while the Qualisys motion capture system recorded three-dimensional scapular kinematic data according to the International Society of Biomechanics recommendations. SFT was applied to the participants’ torso aligned with the lower trapezius, and the same movements were repeated.Results: In the SP group, the scapula was tilted more posteriorly after the application of SFT as compared to before at ball release and maximally externally rotated humerothoracic joint during tennis serve (t=-5.081, p=0.004 and t=-2.623, p=0.047, respectively). In the NSP group, the scapula was tilted more posteriorly with SFT as compared to without at first 75% timing of the cocking phase and maximally externally rotated humerothoracic joint (t=-3.733, p=0.010 and t=-2.510, p=0.046, respectively). And the SP group exhibited a more rotated scapula externally after the application of SFT as compared to before at Ball impact (t=5.283, p=0.003).Conclusions: SFT had a positive immediate effect on the scapular posterior tilting and external rotation during certain phases of the tennis serve among tennis athletes with and without shoulder pain. These findings may help clinicians and sports practitioners to prevent and rehabilitate shoulder injuries for overhead athletes.

Abstract
BackgroundPay-for-performance system (P4P) has been in operation in the Turkish healthcare sector since 2004. While the government defended that it encouraged healthcare professionals’ job motivation, and improved patient satisfaction by increasing efficiency and service quality, healthcare professionals have emphasized the system’s negative effects on working conditions, physicians’ trustworthiness, and cost-quality outcomes. In this study, we investigated physicians’ accounts of current working conditions, their status as a moral agent, and their professional attitudes in the context of P4P’s perceived effects on their professional, social, private, and future lives. MethodsFirst, we held 3 focus groups with 19 residents and 1 specialist regarding their lived experiences under P4P and thematically analyzed the transcripts. Second, we developed a questionnaire in order to assess how generalizable the qualitative findings are for a broader group of physicians. The tool has three parts questioning 1) demographic information, 2) working conditions, and 3) perceived consequences and effects of P4P. 2136 physicians responded to the survey. After refining the data, we conducted the statistical analysis over 1378 responses by using Spearman's correlation coefficient, exploratory factor analysis (EFA) for categorical data, and Kruskal-Wallis variance analysis.ResultsThematic analysis revealed two dimensions: 1) factors leading to estrangement, and 2) manifestations of estrangement. As for the initial, participants thought that P4P affected relationships at work; family and social relationships; working conditions; quality of the specialty training; quality of healthcare services; and it caused healthcare system-related consequences. Concerning the latter, the following themes emerged: Estrangement of the physician; damaging effects on physician’s psychology; physician’s perception of their future life; and physician as a moral agent. According to EFA, a 5-factor structure was appropriate: F1) Estrangement; F2) adverse effects on the physician’s quality of life; F3) favorable consequences; F4) physicians becoming disreputable; F5) unfavorable consequences.ConclusionsThe findings suggest that under P4P, physicians have become more estranged towards their profession, their patients, and themselves. They suffer from deteriorating working conditions, lack of motivation, lack of work-related satisfaction, and hopelessness regarding their future. Furthermore, P4P impairs their ability to realize themselves as moral subjects practicing in alignment with professional values and principles.

Abstract
This survey was performed to aim of synthesize Nano emulsion from Ferula gummosa essential oil (FEGO-NE) and to evaluate its anti-tumor effect.First, Ferula gummosa essential oil was analyzed by GC-MS method, then the Nano emulsion was synthesized as O/W and after characterization by DLS, Zeta potential, AFM, FESEM and TEM methods, its toxicity was evaluated by MTT method. Then its pro-apoptotic effects were evaluated by qPCR (Caspase3, 9, Bax and Bcl-2) method and AO/PI staining. The cancer induction model was used to evaluate the antitumor effects in Balb/C mice. The anti-angiogenic and antioxidant effects were evaluated by qPCR (VEGF, CAT and SOD) method.The results of physicochemical studies showed the formation of nanoparticles with dimensions of 24.6 nm, dispersion index of 0.41 and zeta potential of -28.5 mV with a spherical morphology. The Nano emulsion synthesized at a concentration of 2.9 μg/ml inhibited about 50% of ht-29 cells, while up to a concentration of 4 μg/ml showed no inhibitory effect on normal cells. Increase of caspase 3, 9 and Bax and decrease of BCL-2 gene expression along with increase of apoptotic cells in AP / PI staining confirmed induction of apoptosis by FEGO-NE. The FEGO-NE showed an inhibitory effect on angiogenesis and an additive effect on the expression of antioxidant genes. In addition, the reduction of tumor volume (69.72% in 14 days) in samples treated with FEGO-NE was confirmed. The results of this study showed that FEGO-NE by various mechanisms are able to inhibit cancer cells and have a reducing effect on induced tumors in the in vivo model. These results suggest FEGO-NE as a suitable candidate for cancer therapy studies.

Published: February 2022

Abstract
Purpose
To test the hypothesis that routine dental radiographs can be used to draw conclusions regarding inferior alveolar nerve (IAN) localization.
Methods
A total of 108 radiographs (36 orthopantomograms [OPTs], 36 lateral cephalograms [LCs], and 36 cone-beam computed tomograms [CBCTs]) of 36 patients were analyzed. Cephalometric parameters obtained through OPTs and LCs were correlated with CBCT scans for predictability of IAN localization.
Results
The IAN ran along the lingual half (n = 24) twice as often as in the buccal half (n = 12) in population of the study. The position was always symmetrical contralaterally. No sex-specific correlations were observed (p = 0.34). Lingual nerve courses correlated with enlarged and buccal courses with reduced jaw angles (p = 0.003 / p = 0.010). An increased jaw angle was significantly correlated with a more cranial nerve position; a deep and distal bite position was significantly correlated with a caudal and buccal nerve position (p = 0.020). Moreover, an increase of 1 point in the Hasund score predicted an increased probability of a buccal nerve position by 18.6%. The jaw angle analyzed in OPT, and LC images were positively correlated (r = 0.89, p < 0.001).
Conclusions
Routine dental radiographs provide meaningful conclusions about IAN localization in the vertical and transverse dimension prior CBCT scans. This finding could be used during the initial consultation and treatment planning to weigh more invasive diagnostic methods further down the line.

Published: February 2022

Abstract
Background
The COVID-19 has greatly impacted people's health, especially mental health. This study aimed to compare the psychological status of pregnant women before and after the COVID-19 outbreak.
Method
Participants were recruited (from September 29, 2019, to November 5, 2020) and screened by the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder Scale (GAD-7). The study participants were categorized into three groups based on two turning-point days: January 23, 2020, when China initiated a locked-down strategy, and May 11, 2020, when Shanghai’s COVID epidemic situation became stable.
Results
We recruited 478 pregnant women. After the outbreak, the depression rate (PHQ-9≥5) increased 12.3% (from 35.4–47.7%, P=0.022), and the anxiety rate (GAD-7≥5) was stable (13.3% VS 16.2%, P=0.46). The multivariable logistic regression results further confirmed that the odds of depression in pregnant women increased 79% after the outbreak (aOR=1.79, 95%CI: 1.14-2.79). Under the epidemic, the median depression scale score was still statistically higher after the epidemic situation was stable (5.0 vs. 4.0, P=0.028).
Conclusion
The depression rate increased among pregnant women after the outbreak and was not recovered after the epidemic turned normal among pregnant women. Health institutes should pay attention to the long-term influence of the pandemic.

Abstract
Continuous field studies on the abundance and distribution of freshwater snails and cercarial populations are important for schistosomiasis control programs. In the present work, snail surveys and cercariometry were conducted for four successive seasons at 12 sites on the Nile River banks in the area of Greater Cairo to identify potential transmission foci for schistosomiasis. In addition, water physicochemical parameters were recorded. The results showed that the electrical conductivity, total dissolved solids, dissolved oxygen, and pH were within the permissible levels, except that the water temperature showed an increase, especially in the spring season. Malacological surveys identified 10 native snail species at the studied sites of the Nile River, namely Bulinus truncatus, Biomphalaria alexandrina, Lymnaea natalensis, Lanistes carinatus, Cleopatra bulimoides, Melanoides tuberculata, Helisoma duryi, Bellamya unicolor, Physa acuta, Thedoxus niloticus, and one invasive snail species, Thiara scabra. The calculated diversity index indicated that the structure of snails’ habitats was poor, while Evenness index indicated that the individuals were not distributed equally. Results of natural infection identified no schistosome cercariae in B. truncatus and B. alexandrina. However, results of the cercariometry recovered Schistosoma cercariae in all the surveyed sites during all seasons with variable distribution. The preceding data suggest that, there are still some active transmission foci for schistosomiasis infection in the Nile River. Moreover, the present finding highlights the importance of cercariomety as a complementary approach to snail samplings for the identification of transmission foci for schistosomiasis.

Authors: Mironeasa Silvia , Coţovanu Ionica 
Published: February 2022

Abstract
The aim of this research is to investigate the molecular features and microstructure amaranth flour (AF) fractions and their partial replacement effect of wheat flour (WF) on the chemical composition, dough dynamic rheology, technological and sensory characteristics of bread. The microstructure and molecular characteristics of AF were depending on their particle size (PS). When WF replacement increased and PS decreased the composite flour was richest in protein, lipids, and ash, while the moisture and carbohydrates of these flours decreased. Dynamic rheological behavior revealed significant variations depending on PS and replacement level. Bread volume and firmness increased when more than 15% AF from large PS replaced WF, while medium and small PS at 5–15% replacements was increased the loaf porosity. Chroma values decreased and samples became darker when the replacement level increased. Moreover, replacement of WF with various AF fractions impacted bread sensory characteristics, obtaining better acceptance for large and medium PS up to 10%.
