Abstract
Background: Coronavirus disease 2019 (COVID-19) has infected people in many countries worldwide. Discovering an effective treatment for this disease, particularly in severe cases, has become the subject of intense scientific investigation. Therefore, the objective of this study was to evaluate the efficacy of intravenous immunoglobulin (IVIg) in patients with severe COVID-19 infection.Methods: This study was conducted as a randomized placebo-controlled double-blind clinical trial. Fifty-nine patients with severe COVID-19 infection who did not respond to initial treatments were randomly assigned into two groups. One group received IVIg (human)—four vials daily for three days (in addition to initial treatment), while the other group received a placebo. Patients’ demographic, clinical, and select laboratory test results, as well as the occurrence of in-hospital mortality, were recorded.Results: Among total study subjects, 30 patients received IVIg and 29 patients received a placebo. Demographics, clinical characteristics, and laboratory tests were not statistically different (P > 0.05) between the two groups. The in-hospital mortality rate was significantly lower in the IVIg group compared to the control group (6 [20.0%] vs. 14 [48.3%], respectively; P = 0.022). Multivariate regression analysis demonstrated that administration of IVIg did indeed have a significant impact on mortality rate (aOR = 0.003 [95% CI: 0.001–0.815]; P = 0.042).Conclusions: Our study demonstrated that the administration of IVIg in patients with severe COVID-19 infection who did not respond to initial treatment could improve their clinical outcome and significantly reduce mortality rate. Further multicenter studies with larger sample sizes are nonetheless required to confirm the appropriateness of this medication as a standard treatment.Trial registration: A study protocol was registered at the Iranian Registry of Clinical Trials (www.IRCT.ir), number IRCT20200501047259N1. It was registered retrospectively on May 17th, 2020.

Abstract
Background: Tumor metastasis is the main cause of death from breast cancer patients and cell migration plays a critical role in metastasis. Recent studies have shown long non-coding RNAs (lncRNAs) play an essential role in the initiation and progression of cancer. In the present study, the role of a LncRNA, ARHGAP5-AS1 in breast cancer was investigated.Methods: Bioinformation was analyzed for the expression of ARHGAP5-AS1. qRT-PCR was conducted to verify the expression of ARHGAP5-AS1 in breast cancer specimens. Transwell migration assays and F-actin staining were utilized to estimate cell migration ability. RNA pulldown assays and RNA immunoprecipitation were used to prove the interaction between ARHGAP5-AS1 and SMAD7. Western blot and immunofluorescence imaging were used to examine the protein levels. Dual luciferase reporter assays were performed to evaluate the activation of TGF-β signaling.Results: Compared to MDA-MB-231 cells, the expression of LncRNA ARHGAP5-AS1(NR_027263) was significantly suppressed in its highly metastatic subtype MDA-MB-231-LM2 cells. Functional study showed ARHGAP5-AS1 could inhibit cell migration via suppression of stress fibers in breast cancer cell lines. Afterwards, SMAD7 was further identified to interact with ARHGAP5-AS1 by its PY motif and thus its ubiquitination and degradation was blocked due to reduced interaction with E3 ligase SMURF1 and SMURF2. Moreover, ARHGAP5-AS1 could inhibit TGF-β signaling pathway due to its inhibitory role on SMAD7.Conclusions: Overall, these findings demonstrate that ARHGAP5-AS1 inhibits breast cancer cell migration and could server as a novel biomarker for breast cancer metastasis and a potent target for the treatment in the future.

Abstract
BackgroundCognitive impairment is twice more frequent in elderly with type 2 diabetes mellitus (DM). This study was conducted to determine the association between glycemic control and cognitive performance among community-dwelling elderly persons in Mexico.MethodsCross-sectional study conducted in individuals aged 60 years or elderly participating in the 2012 Mexican Health and Aging Study. Type 2 DM participants were classified in 3 groups according to their glycated hemoglobin levels (HbA1c): <7% (intensive control), 7-7.9% (standard control) or ≥ 8% (poor control), and cognitive performance: low (CCCE ≤44 points), intermediate (44.1-59.52 points), or high (≥59.53 points). Multinomial logistic regression models were constructed to determine this association.Results216 community-dwelling adults aged 60 and older with type 2 diabetes were selected. Subjects in the low cognitive performance group were older (69.7 ± 6.6 vs 65.86 ± 5.18 years, p <.001) and had a lower educational level (2.5 ± 2.6 vs 7.44 ± 4.15 years, p <.000) when compared to the high cognitive performance participants. HbA1c ≥8% was associated with having low (Odds Ratio (OR) 3.17, 95% CI 1.17-8.60, p=.024), and intermediate (OR 3.23, 95% CI 1.27-8.20, p=.014) cognitive performance; this trend was not found for HbA1c 7.0-7.9% group.The multinomial regression analysis showed that the presence of HbA1c ≥8% (poor glycemic control) was associated with low (OR 3.17, 95% CI = 1.17-8.60, p=.024), and intermediate (OR 3.23, 95% CI = 1.27-8.20, p=.014) cognitive performance. After adjusting for confounding variables.ConclusionsGlycemic control with a HbA1c ≥ 8% was associated with worse cognitive performance.

Abstract
Objective: Although, several studies have illustrated that there is a relation between the between dietary inflammatory index (DII) with obesity-related parameters, and inflammation, their results were controversial results. This study aimed to investigate this relationship among Iranian women.Results: Multivariable linear regression showed that fat mass was 0.14 kg lower in the anti-inflammatory diet group, with respect to the pro-inflammatory group, after adjusting covariates such as age, physical activity, economic and job status (β = -0.142, 95% CI -4.44, -1.71, P = 0.03). Fat-free mass (FFM) was 1.5 kg more in the anti-inflammatory diet group, compared to the pro-inflammatory diet group, after adjusting for potentials cofounders (β = 1.50, 95% CI 0, 3.01, p = 0.05). Furthermore, after adjusting for potentials cofounders, it was revealed that the subjects with lower DII had lower monocyte chemoattractant protein-1 (MCP-1) levels in serum (β = -18.81, 95% CI -35.84, -1.79, p = 0.03). These findings suggest an inverse and significant relationship between DII and FFM and also DII is directly related to Fat mass and the level of MCP-1. This finding can be used for developing interventions that aim to promote healthy eating to prevent inflammation and non-communicable disease development among obese female.

Abstract
Background: Psoroptes cuniculi is a global common ectoparasite of wild and domestic rabbits and causes an economically devastating loss and serious welfare issues of commercial rabbit husbandry. Serine proteinase inhibitor (Serpin) is present in almost all organisms that are involved in host-pathogen interactions, inflammatory responses, and reproductive development, etc. However, the research on P. cuniculi serpins is still limited.Methods: In this study, two serpin genes of P. cuniculi (Pso c 27 and PsoSP2 cDNAs) were cloned, and the molecular characterization was analyzed. The transcriptional profiles and tissue localization of these two serpins in P. cuniculi were investigated by quantitative real-time PCR and immunohistochemistry, respectively. The potential function of recombinant Pso c 27 and PsoSP2 (rPso c 27and rPsoSP2) in the serodiagnosis of P. cuniculi infestation in rabbits were evaluated by indirect enzyme-linked immunosorbent assay (iELISA). Results: Both of the 523 residue Pso c 27 and the 240 residue PsoSP2 proteins contained typical serpin domains and signatures. Both Pso c 27and PsoSP2 cDNAs expressed throughout the life cycle, more specifically, significantly higher expression in female mites than the larva, nymph, and male mites (Pso c 27, F(3, 8) = 1935.953, p < 0.0001; PsoSP2, F(3, 8) = 660.669, p < 0.0001). The native Pso c 27 and PsoSP2 localized in ovary and mouthpart of adult female mites, respectively. Compared to rPsoSP2, the rPso c 27 displayed better diagnostic efficiency with higher values of sensitivity, specificity and the area under the receiver operating characteristic curve (AUC) (rPso c 27 - rPsoSP2: 96.0% - 90.0%; 90.91% - 78.18%; 0.988 - 0.964, respectively). Moreover, the rPso c 27 showed seropositive in 80% rabbits as early as the 2nd week post-infestation (p.i.), prior to visible clinical signs and microscopy-positive of skin scrapings. Conclusions: These results suggested that these two serpins may play essential roles in reproductive development, serum-feeding, and pathogenicity of P. cuniculi. Compared to PsoSP2, Pso c 27 appeared as a potential antigen for serodiagnosis of P. cuniculi infestation in rabbits, especially at the early stage of infestation.

Abstract
Background: The national wide lockdown order imposed in early April 2020 due to the COVID-19 pandemic complicated mosquito control activities across the United States (US), and Florida is no exception. Mosquito control programs are the first line of defense against mosquitoes-borne pathogens in the state of Florida. The purpose of this study was to examine the capabilities of Florida mosquito programs to implement key mosquito measures during the COVID-19 pandemic.Methods: In a self-administered online survey, we examined capabilities of all Florida mosquito control programs during the COVID-19 pandemic (both state-approved mosquito districts (N=63) and open programs (N=27). Descriptive statistics were used to summarize information about the characteristics of responding programs, as well as the implemented mosquito control and surveillance activities. We used bivariate analysis to compare the characteristics of these responding programs and the self-reported mosquito measures.Results: Of the recruited mosquito control programs, 77 completed the survey (85.6% response rate; 77/90). Of these, 57.5% (n=42) were Board of County Commissioners (BOCC) mosquito control programs, 21.9% (n=16) were independent tax district programs, 13.7% (n=10) were municipal mosquito control programs, and only 6.8% (n=5) were either health or emergency department mosquito control programs. Except for arbovirus surveillance, most programs either fully or partially performed larval (61.8%) and adult (78.9%) surveillance; and for Aedes aegypti (85.2%, n=54), Aedes albopictus (87.3%, n=55), Culex quinquefasciatus (92.1%, n=58), and Culex nigripalpus (91.9%, n=57).Conclusions: Findings underscore the importance of ongoing mosquito control activities and suggests that Florida mosquito control programs are vigilant and have significant capability to handle potential mosquito-borne disease threats, but arbovirus surveillance systems; laboratory testing of mosquito pools and testing of human and nonhuman specimens for arboviruses are needed during pandemics as well.

Abstract
Background: Scylla paramamosain is one of the commercially crucial marine crustaceans belonging to the genus Scylla , which is commonly distributed along the coasts of China, Vietnam, and Japan. Genomic and transcriptomic data are scarce for the mud crab. Light intensity is one of the ecological factors that affect S. paramamosain during indoor overwintering. To understand the energy metabolism mechanism adapted to light intensity, we analyzed the transcriptome of S. paramamosain hepatopancreas in response to different light intensities (0, 1.43, 40.31 μmol·m -2 ·s -1 ). Results: A total of 5052 differentially expressed genes were identified in low light group (LL group, 3104 genes were up-regulated and 1948 genes were down-regulated). A total of 7403 differentially expressed genes were identified in high light group (HL group, 5262 genes were up-regulated and 2141 genes were down-regulated). S. paramamosain adapts to different light intensity environments through the regulation of amino acids, fatty acids, carbon and energy metabolism. Different light intensities had a strong impact on the energy generation of S. paramamosain by influencing oxygen consumption rate, aerobic respiration, glycolysis/gluconeogenesis pathway, the citrate cycle (TCA cycle) and fatty acid degradation. Conclusion: Low light is more conducive to the survival of S. paramamosain , which needs to produce and consume relatively less energy to sustain physiological activities. In contrast, S. paramamosain produced more energy to adapt to the pressure of high light intensities. The findings of the study add to the knowledge of regulatory mechanisms related to S. paramamosain metabolism under different light intensities.

Published: October 2020

Abstract
There is evidence of connections between soil organic carbon (SOC) and inorganic carbon (SIC) in dryland of north China. However, fractions of SOC and SIC and the relationship are not well understood in the Loess Plateau that undergoes profound erosion and redeposition. A study was conducted in low-elevation cropland of Loess Plateau across two distinctive basins: Linfen basin (LFB) with lower soil pH (<8.4) and subject to erosion-redeposition, and Yuncheng basin (YCB) with higher soil pH (>8.6) and under the influence of the Yellow River. Soil samples were collected from 30 sites over 100 cm. We determined SOC, SIC, dissolved organic carbon (DOC) and other properties. Above 100 cm, SOC stock is significantly higher in LFB (10.0±2.6 kg C m-2) than in YCB (6.9±1.5 kg C m-2), but SIC lower in LFB (14.0±2.5 kg C m-2) than in YCB (17.0±5.7 kg C m-2). We find a significantly negative correlation between SOC and SIC stocks in LFB, but no clear relationship in YCB. DOC:SOC ratio (an indicator for DOC desorption or SOC stability) is significantly higher below 40 cm in YCB (1.9%) than LFB (1.2%), indicating stronger DOC desorption in YCB that has stronger hydrological process due to the influence of the Yellow River. Overall, SOC has a negative correlation with SIC and soil pH, and DOC:SOC ratio has a significantly positive correlation with soil pH. Our analyses suggest that erosion/re-deposition of topsoil is partly responsible for the negative SIC-SOC relationship in LFB, and high soil pH and stronger hydrological processes are attributable to relatively lower levels of SOC in YCB. This study highlights that soil carbon fractions in the lowland of Loess Plateau are influenced by many drivers, which leads to complex relationships between major soil carbon pools.

Abstract
Purpose: The aim of this study was to evaluate the long-term treatment results of combined superselective intraarterial chemotherapy and radiation therapy for advanced maxillary sinus cancer (MSC) and the incidence of regional lymph node failure, and to reveal the clinical and anatomical predictive factors for metastasis. Methods: We retrospectively evaluated 55 consecutive patients with locally advanced squamous cell carcinoma of the maxillary sinus who were treated with external radiotherapy and superselective intraarterial chemotherapy. Elective nodal irradiation (ENI) was performed only in the clinical node-positive (cN+) cases and not in the clinical node-negative (cN0) cases. Results: Thirty-eight patients were cN0, and 17 were cN+ at diagnosis. Regional lymph node metastases occurred in 7 of 38 patients with cN0, and 2 of 17 with cN+ during the median follow-up period of 36 months. There were more cases of high-grade (3 or 4) late adverse events in the ENI group than in the non-ENI group (13% vs. 41%, respectively; p = 0.03). In cN0 cases without ENI, invasion of the pterygoid plates (57% vs. 90%; p < 0.01) and oral cavity (35% vs. 92%; p = 0.02) was significantly correlated with a low 5-year regional recurrence-free rate. Conclusions: Patients with MCS and invasion of the pterygoid plates and oral cavity can be considered appropriate candidates for ENI.

Abstract
Background: Drought stress is an adverse factor with deleterious effects on several aspects of rice growth. However, the mechanism underlying drought resistance in rice remains unclear. To understand the molecular mechanism of the drought response in rice, drought-sensitive CSSL (Chromosome Single-substitution Segment Line) PY6 was used to map QTLs of sensitive phenotypes and to reveal the impact of the QTLs on transcriptional profiling.Results: The QTL dss-1 was mapped onto the short arm of chromosome 1 of rice. According to transcriptomic analysis, the identified differentially expressed genes (DEGs) exhibited a downregulated pattern and were mainly enriched in photosynthesis-related GO terms, indicating that photosynthesis was greatly inhibited under drought. Further, according to weighted gene coexpression network analysis (WGCNA), specific gene modules (designating a group of genes with a similar expression pattern) were strongly correlated with H2O2 (4 modules) and MDA (3 modules), respectively. Likewise, GO analysis revealed that the photosynthesis-related GO terms were consistently overrepresented in H2O2-correlated modules. Functional annotation of the differentially expressed hub genes (DEHGs) in the H2O2 and MDA-correlated modules revealed cross-talk between abiotic and biotic stress responses for these genes, which were annotated as encoding WRKYs and PR family proteins, were notably differentially expressed between PY6 and PR403.Conclusions: We speculated that drought-induced photosynthetic inhibition leads to H2O2 and MDA accumulation, which can then trigger the reprogramming of the rice transcriptome, including the hub genes involved in ROS scavenging, to prevent oxidative stress damage. Our results shed light on and provide deep insight into the drought resistance mechanism in rice.

Abstract
Background: Early detection of Zika virus (ZIKV) infection during the viremia and viruria facilitates proper patient management and mosquito control measurement to prevent disease spread. Therefore, a cost-effective nucleic acid detection method for the diagnosis of ZIKV infection, especially in resource-deficient settings, is highly required.Methods: In the present study, a single-tube reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for the detection of both the Asian and African-lineage ZIKV. The detection limit, strain coverage and cross-reactivity of the ZIKV RT-LAMP assay was evaluated. The sensitivity and specificity of the RT-LAMP were also evaluated using a total of 24 simulated clinical samples. The ZIKV quantitative reverse transcription-polymerase chain reaction (qRT-PCR) assay was used as the reference assay.Results: The detection limit of the RT-LAMP assay was 3.73 ZIKV RNA copies (probit analysis, P ≤ 0.05). The RT-LAMP assay detected the ZIKV genomes of both the Asian and African lineages without cross-reacting with other arthropod-borne viruses. The sensitivity and specificity of the RT-LAMP assay were 90% (95% CI = 59.6 – 98.2) and 100% (95% CI = 78.5 – 100.0), respectively. The RT-LAMP assay detected ZIKV genome in 9 of 24 (37.5%) of the simulated clinical samples compared to 10 of 24 (41.7%) by qRT-PCR assay with a high level of concordance (k = 0.913, P < 0.001).Conclusion: The RT-LAMP assay is applicable for the broad coverage detection of both the Asian and African ZIKV strains in resource-deficient settings.
