Authors: Nonomura Yuusuke 
Published: January 2021

Abstract
Purpose: Candida albicans (CA) is a major pathogenic fungus that causes a critical infection and life-threatening disease. During ventilator usage for the treatment of COVID-19-associated pneumonia, CA colonization of the airway should be prevented to avoid an increase in mortality. Our aim was to characterize and analyze the infection of Candida albicans (CA) for eradication.Methods: We characterized and analyzed the infection source and infection field which are carrier field, diffusion field, and spread field, by using a new infection examination (diagnostic) system (IEDS) comprising a new dental formula (measurement analysis) medium (DFM) with time, space, and phase, and the simultaneous relative differential equations (C4RDE).Results: This study showed that CA was not an endogenous microorganism, but a fungus that infected teeth causing dental caries that was successfully eradicated from all teeth of 353 Japanese patients (oral cavity segment). [In the first examination, the percentages of people with CA (+) was 40.5% (the DMFT: 62.8%) and CA(-) was 56.4% (the DMFT: 47.1%). The difference in DMFT was 15.7% (P<0.01)] (DMFT is decayed, missing, and filled tooth index).Conclusion: Our methods help to eradicate the infection source (IS), prevent critical infection, and reduce mortality. The IEDS is a powerful tool that can be applied for any microbial infection easily. It is possible for the dentists to characterize CA by IEDS and eradicate CA from the oral cavity.

Abstract
Background: Ferroptosis is a newly described form of regulated cell death, targeting nuclear factor erythroid-2-related factor 2 (Nrf2) -mediated ferroptosis may be an attractive option to counteract malignant tumor. Whether miR-144-5p sensitize erastin-induced ferroptosis in gastric cancer via regulation of Nrf2 pathway is unclear. Methods: To speculate the function of miR-144-5p in cancers, bioinformatic analysis was performed. Dual-luciferase reporter gene assay was used to predict effect of miR-144-5p on the expression of Nrf2. The expressions of miR-144-5p and Nrf2 in human gastric cancer cell lines and tissues were detected by qPCR, Immunohistochemistry or western blot. Results: miR-144-5p, identified to wreck Nrf2 mRNA, was selected and overexpressed in gastric cancer cells to sensitize erastin-induced ferroptosis. Ectopic expression of miR-144-5p in AGS and BGC-823 cells downregulated the mRNA and protein expression of Nrf2. In addition, AGS and BGC-823 cell lines with exogenous expression of miR-144-5p were more sensitive to erastin-induced ferroptosis with overgeneration of lipid reactive oxygen species and depletion of glutathione. Conclusions: miR-144-5p sensitizes erastin-induced ferroptosis via abrogating expression of Nrf2 to eliminate cancer cells selectively with high Nrf2 pathway activation.

Abstract
Background: Atypical chemokine receptors (ACKRs), including DARC, D6 and CCX-CKR, hold very critical roles in cancer invasion and metastasis. The objective of the present study was to determine preliminarily the predictive value of ACKRs in colorectal cancer (CRC). Methods: From 2012 to 2019 in the First Affiliated Hospital of Dalian Medical University, 44 CRC patients were followed up. We performed immunohistochemical analysis, Western blot and RT-PCR analysis on CRC and adjacent normal tissues for investigating the expression of ACKRs and their relationships to clinicopathologic features and survival rate. Results: The expression of three ACKRs, CCX-CKR, DARC and D6, in normal colon tissues is higher than that in colorectal cancer tissues. Meanwhile, the expression of corresponding ligands CCL21, CCL2 and CCL22 shows the opposite. Low expression of ACKRs in colon cancer tissues was closely related to the potential of lymph node metastasis (P= 0.001). When compared with triple-negative ACKR expression, co-expression of the ACKRs predicted better outcomes of colorectal cancer patients with statistical significance (P=0.011). Conclusions: The loss of ACKRs may play important roles in lymph node metastasis of CRC. ACKR expression may be considered as prognostic markers in CRC patients.

Published: January 2021

Abstract
Background: Globally, pneumonia is the first infectious disease which is the leading cause of children under age five morbidity and mortality with 98% of deaths in developing countries. Objective: The study aimed to identify the determinant factors that jointly affect the longitudinal measures of pneumonia (respiratory rate, pulse rate and oxygen saturation) and time to convalescence or recovery of under five admitted pneumonia patients at Felege Hiwot Referral Hospital, Bahir Dar, Ethiopia.Methods: A prospective cohort study design was used on 101 sampled under five admitted pneumonia patients from December 2019 to February 2020. The study was conducted using joint model of longitudinal outcomes and survival outcomes.Results: The significant values of shared parameters in the survival sub model shows that the use of joint modeling of multivariate longitudinal outcomes with the time to event outcome is the best model compared to separate models. The estimated values of the association parameters for γ_1, γ_2 and γ_3 were -0.297, -0.121 and 0.5452 respectively and indicates that; respiratory rate and pulse rate were negatively related with recovery time, whereas oxygen saturation was positively associated with recovery time. As age of patients increased by one month, the average respiratory rate and pulse rate were significantly decreased by 0.3759 bpm and 1.1012 bpm respectively keeping other variables constant, but age has no information about oxygen saturation. Conclusion: Residence, birth order, severity and visit were found as determinants of the longitudinal measures of pneumonia and time to recovery of under-five admitted pneumonia patients jointly. To improve child survival, the community should be responsible for post ponding child birth and marriage.

Abstract
BackgroundDisruption of the endothelial glycocalyx (eGC) is observed in septic patients and its injury is associated with multiple-organ failure and inferior outcomes. Besides this biomarker function, increased blood concentrations of shedded eGC constituents might play a mechanistic role in septic organ failure. We hypothesized that therapeutic plasma exchange (TPE) against fresh frozen plasma might influence eGC related pathology.MethodsWe enrolled 20 norepinephrine dependent (NE > 0.4μg/kg/min) patients with early septic shock (onset < 12h). Sublingual assessment of the eGC via sublingual sidestream darkfield (SDF) imaging was performed. Plasma eGC degradation products such as heparan-sulfate (HS) and the eGC regulating enzymes, heparanase (Hpa)-1 and Hpa-2, were obtained before and after TPE. A 3D microfluidic flow assay was performed to examine the effect of TPE on eGC ex vivo. Results were compared to healthy controls.ResultsSDF demonstrated a marked decrease in eGC thickness in septic patients compared to healthy individuals (p=0.001). Circulating HS levels were increased more than six-fold compared to controls and decreased significantly following TPE (controls: 16.9 (8-18.6) vs. septic patients before TPE: 105.8 (30.8-143.4) μg/ml, p<0.001; vs. after TPE: 70.7 (36.9-109.5) μg/ml, p<0.001). The Hpa-2 /Hpa-1 ratio was markedly reduced in septic patients before TPE but normalized after TPE (controls: 13.6 (6.2-21.2) vs. septic patients at inclusion: 2.9 (2.1-5.7), p=0.001; vs. septic patients after TPE: 13.2 (11.2-31.8), p<0.001). Ex vivo stimulation of endothelial cells with serum from septic patients induced eGC damage that could be attenuated with serum post TPE.ConclusionsSeptic shock results in profound degradation of the eGC and an acquired deficiency of the protective regulator Hpa-2. TPE removed potentially injurious eGC degradation products and partially attenuated Hpa-2 deficiency.Trial registrationclinicaltrials.gov NCT04231994, retrospectively registered 18 January 2020
Financial Development and Economic Growth in Nepal: An ARDL Bound Test Approach
Authors: Panthi Pradeep 
Published: January 2021

Abstract
This study empirically examines the dynamic relationship between financial development and economic growth in Nepal using annual time series data from 1985 to 2016. The financial development is measured by domestic credit to the private sectors, domestic credit to the private sectors by banks, broad money (M2) and net domestic credit, separately. All are ratios to GDP. The economic growth is measured by real GDP per capita. The bound test approach of cointegration under autoregressive distributed lag (ARDL) model reveals that Nepal’s financial development and economic growth are cointegrated with bi-directional causality in the long-run. Thus, the study concludes that financial development and economic growth positively and significantly impact each other. The causal effects running from financial development to economic growth are portent then economic growth to financial development. However, the speed of adjustment towards long-run equilibrium, directing from economic growth to financial development is reasonably robust. There is one-directional reverse causality running from economic growth to financial development in the short-run. Therefore, the study suggests policymakers to prioritize policies to develop a well-functioning financial sector to enhance economic growth, especially for developing countries like Nepal.JEL ClassificationsG21, C22, F43, O11, O16

Abstract
Background: To enhance durable viral suppression and upgrade CD4 cell immune function of HIV-1 proviral DNA positive infants, Gambia government adopted WHO recommended sample collection from infants born to HIV infected mothers before or at 6-8 weeks soon after birth, then ensure 4 weeks’ timeframe from collection dates, through molecular testing, to ART initiation if positive. Despite, studies to determine if these infants sample were collected, tested and initiated on ART within the adopted recommended timeframe, to ensure their achievements of this benefit are lacking. Aims: We aimed to determine the effect of delayed in diagnosis and ART initiation on CD4 cell and viraemia outcome of HIV-1 proviral DNA positive infants in the Gambia. Method: 2015-2019 retrospective data collection and analysis of key dates, initial viraemia and CD4 cell outcome, and then prospective cohort study on CD4 cell and viraemia outcome of those followed within at least 6 months and at most 3 years duration on ART adherence. STATA version 13 was used for the data analysis. Delayed in diagnosis and ART initiation was dichotomized using the adopted recommended timeframe, and Pair T-test used to determine the difference between mean initial and mean prospective, CD4 cell and viraemia outcome respectively.Results: Between 2015-2019, 95 infants were found tested HIV-1 proviral DNA positive among which, 49/95 were found initiated on ART 42 weeks (IQR: 25, 83) median time from their delivery dates. Among these 49, 4 found adhered to the duration in the cohort of those not affect by the delays, difference between their mean initial and prospective CD4 cell outcome was found significantly (P = 0.02) higher than the 11 found adhered to the duration in the cohort of those affected by the delays (P = 0.37).The reverse was found in their viraemia outcome although, not statistically significant for both (P values = O.33 and 0.18 respectively). Conclusion: The overall 42 weeks median time was found in conflict with the adopted recommended timeframe thus, found affected the CD4 cell and viraemia outcome of positive infants affected by the delays. Henceforth, the urgent attention is required for those affected to improve their prognosis.
Programmable Nonreciprocal Meta-Prism

Published: January 2021

Abstract
Optical prisms are made of glass and map temporal frequencies into spatial frequencies by decomposing incident white light into its constituent colors and refract them into different directions. Conventional prisms suffer from their volumetric bulky and heavy structure and their material parameters are dictated by the Lorentz reciprocity theorem.. Considering various applications of prisms in wave engineering and their growing applications in the invisible spectrum and antenna applications, there is a demand for compact apparatuses that are capable of providing prism functionality in a reconfigurable manner, with a nonreciprocal/reciprocal response. Here, we propose a nonreciprocal metasurface-based prism constituted of an array of phase-and amplitude-gradient frequency-dependent spatially variant radiating super-cells. In conventional optical prisms, nonreciprocal devices and metamaterials, the spatial decomposition and nonreciprocity functions are fixed and noneditable. Here, we present a programmable metasurface integrated with amplifiers to realize controllable nonreciprocal spatial decomposition, where each frequency component of the incident polychromatic wave can be transmitted under an arbitrary and programmable angle of transmission with a desired transmission gain. Such a polychromatic metasurface prism is constituted of frequency-dependent spatially variant transistor-based phase shifters and amplifiers for the spatial decomposition of the wave components. Interesting features include three-dimensional prism functionality with programmable angles of refraction, power amplification, and directive and diverse radiation beams. Furthermore, the metasurface prism can be digitally controlled via a field-programmable gate array (FPGA), making the metasurface a suitable solution for radars, holography applications, and wireless telecommunication systems.

Abstract
Background: Oral health status is known to be associated with overall health among people living with HIV. However, it is unclear whether dental caries is associated with viral load among this population. In particular, dental caries among children living with HIV needs to be better understood, as this can affect their overall health and future well-being. This study assessed the association between dental caries and viral load among children living with HIV in Phnom Penh, Cambodia.Methods: This cross-sectional study was conducted at the National Paediatric Hospital as a baseline survey of a randomized controlled trial. The study population included children living with HIV aged 3–15 years and their primary caregivers. Calibrated examiners collected data on dental caries status (WHO index) and the latest HIV viral load data stored in the patients’ information system at the hospital. On the day of the dental examination, children’s caregivers and older children were invited to answer a questionnaire-based interview. Multiple logistic regression analysis was conducted to assess the association between dental caries and viral load. The cut-off point for undetectable viral load was set at <40 copies/mL.Results: Data from 328 children were included in the analysis; 68.3% had an undetectable viral load. The mean decayed, missing, or filled permanent/deciduous teeth was 7.7 (standard deviation = 5.0). In the regression analysis, dental caries in permanent or deciduous teeth was positively associated with detectable viral load (adjusted odds ratio: 1.07, 95% confidence interval: 1.01–1.14). Conversely, antiretroviral therapy of ≥1 year and self-reported better adherence to antiretroviral drugs were negatively associated with detectable viral load. Among children with detectable viral load, dental caries in permanent or deciduous teeth was also positively associated with non-suppression of viral load (>1000 copies/mL) (adjusted odds ratio: 1.12, 95% confidence interval: 1.03–1.23).Conclusions: Dental caries was associated with viral load status detection among children living with HIV. This finding suggests that dental caries may affect the immune status of children. The oral health of children living with HIV should be strengthened, and further research is needed to clarify the causal relationship between viral load and oral health status.

Abstract
Background: Gossypium hirsutum L. ( cotton) is one of the most economically important crops in the world due to its significant source of fiber, feed, foodstuff, oil and biofuel products. However, the utilization of cottonseed was limited due to the presence of small and darkly pigmented glands that contain large amounts of gossypol, which is toxic to human beings and non-ruminant animals. To date, some progress has been made in the pigment gland formation, but the underlying molecular mechanism of its formation was still unclear.Results: In this study, we identified an AP2/ERF transcription factor named GhERF105 (GH_A12G2166), which was involved in the regulation of gland pigmentation by the comparative transcriptome analysis of the leaf of glanded and glandless plants. It encoded an ERF protein containing a converved AP2 domain which was localized in the nucleus with transcriptional activity, and showed the high expression in glanded cotton accessions that contained much gossypol. Virus-induced gene silencing(VIGS) against GhERF105 caused the dramatic reduction in the number of glands and significantly lowered levels of gossypol in cotton leaves. GhERF105 showed the patterns of spatiotemporal and inducible expression in the glanded plants. Conclusions: These results suggest that GhERF105 contributes to the pigment gland formation and gossypol biosynthesis in partial organs of glanded plant. It also provides a potential molecular basis to generate ‘glandless-seed’ and ‘glanded-plant’ cotton cultivar.

Abstract
Background: To review the value of the gastrointestinal failure (GIF) score in children with different degrees of traumatic brain injury (TBI) by analyzing the correlation between outcome and gastrointestinal function. Methods: A total of 165 children with TBI who were diagnosed and treated in the surgical intensive care unit (SICU) for longer than 72 h between August 2017 and September 2019 were analyzed. Admission parameters included sex, age, Glasgow Coma Scale (GCS) score, body mass index (BMI), leukocyte count, C-reactive protein (CRP), hemoglobin (Hb) and hematocrit (Hct), blood glucose, lactic acid, procalcitonin (PCT), albumin, plasma osmotic pressure, prothrombin time (PT) and activated partial thromboplastin time (APTT). To predict outcomes, the Pediatric Sequential Organ Failure Assessment (SOFA) score, Pediatric Clinical Illness Score (PCIS), and mean GIF score for the first three days were combined. Results: The percent of patients with gastrointestinal dysfunction on the first day was 78.8%. Food intolerance (FI) and intra-abdominal hypertension (IAH) developed in 36.4% and 21.8% of the patients, respectively. The GIF score and mean GIF score for the first three days in children with different degrees of TBI were significantly different (P<0.05); these scores were also significantly different between patients who died and those who survived (P<0.05). The mean GIF score for the first three days was identified as an independent risk factor for mortality (odds ratio>1, 95% confidence interval=1.457 to 16.016, P<0.01), as was the PCIS. Receiver operating characteristic (ROC) curve analysis suggested that the mean GIF score for the first three days had the same calibrating power as the PCIS in discriminating the risk of death of children. Conclusion: The incidence of gastrointestinal dysfunction in children with TBI is high. The GIF score has the ability to reflect the status of the gastrointestinal system. The mean GIF score for the first three days has high prognostic value for ICU mortality in the SICU.
