Coronavirus disease 2019 (COVID-19) is a viral infection produced by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus epidemic, which was declared a global pandemic in March 2020. The World Health Organization has recorded around 43.3 billion cases and 59.4 million casualties to date, posing a severe threat to global health. Severe COVID-19 indicates viral pneumonia caused by the SARS-CoV-2 infections, which can induce fatal consequences, including acute respiratory distress syndrome (ARDS). The purpose of this research is to better understand the COVID-19 and ARDS pathways, as well as to find targeted single nucleotide polymorphism. To accomplish this, we retrieved over 100 patients' samples from the Sequence Read Archive, National Center for Biotechnology Information. These sequences were processed through the Galaxy server next generation sequencing pipeline for variant analysis and then visualized in the Integrative Genomics Viewer, and performed statistical analysis using t-tests and Bonferroni correction, where six major genes were identified as DNAH7, CLUAP1, PPA2, PAPSS1, TLR4, and IFITM3. Furthermore, a complete understanding of the genomes of COVID-19-related ARDS will aid in the early identification and treatment of target proteins. Finally, the discovery of novel therapeutics based on discovered proteins can assist to slow the progression of ARDS and lower fatality rates.

Nitric oxide (NO) is a small, diffusible, and highly reactive molecule, which plays dichotomous regulatory roles under physiological and pathological conditions. NO promotes apoptosis in some cells, and inhibits apoptosis in other cells. In the present study, we attempted to characterize the NO signaling pathway and cellular response in PC12 cells treated with cytokines. $IFN{\gamma}\;and\;TNF{\alpha}$ treatment resulted in a synergistic increase of nitrite accumulation, with the induction of inducible nitric oxide synthase (iNOS) in the PC12 cells. Moreover, as nitrite concentration increased, cell viability decreased. In order to explore MAP kinase involvement in nitric oxide production resultant from $IFN{\gamma}\;and\;TNF{\alpha}$ stimulation, we measured the activation of MAP kinase using specific MAP kinase inhibitors. PC12 cells pretreated with SB203580, a p38 MAP kinase-specific inhibitor, resulted in the inhibition of iNOS expression and NO production. However, PD98059, an ERK/MAP kinase-specific inhibitor, was not observed to exert such an effect. In addition, Stat1 activated by $IFN{\gamma}\;and\;TNF{\alpha}$ was interacted with p38 MAPK. These data suggest that p38 MAP kinase mediates cytokine-mediated iNOS expression in the PC12 cells, and Jak/Stat pathway interferes with p38 MAPK signaling pathway.

Granulocyte colony-stimulating factor (G-CSF) is a cytokine secreted by stromal cells and plays a role in the differentiation of bone marrow stem cells and proliferation of neutrophils. Therefore, G-CSF is widely used to reduce the risk of serious infection in immunocompromised patients; however, its use in such patients is limited because of its non-persistent biological activity. We created an N-linked glycosylated form of this cytokine, hG-CSF (Phe140Asn), to assess its biological activity in the promyelocyte cell line HL60. Enhanced biological effects were identified by analyzing the JAK2/STAT3/survivin pathway in HL60 cells. In addition, mutant hG-CSF (Phe140Asn) was observed to have enhanced chemoattractant effects and improved differentiation efficiency in HL60 cells. These results suggest that the addition of N-linked glycosylation was successful in improving the biological activity of hG-CSF. Furthermore, the mutated product appears to be a feasible therapy for patients with neutropenia.

To verify the suitability of microwave digestion method for analyzing macro nutrients and metals. K, Ca, Mg, Cu, Zn, and Mn contents in plant and composts were investigated comparing with conventional wet digestion method. Because it takes short time to digest metal samples by using microwave method compared with conventional wet digestion method. Digestion time for metal samples was four to six hours long for wet digestion, while one hour long for microwave digestion. Determinant coefficients of Cu, Mn, Zn, Ca, K, and Mg contents between two analyzing methods were 0.99, 0.99, 0.94. 0.97, 0.98, and 0.91, respectively. In the case of Ca and K, microwave digestion method analyzed their contents relatively low compared with wet digestion method. Meanwhile, microwave digestion method analyzed the contents for Cu, Ma, and Zn relatively high compared with wet digestion method. This study results in that microwave digestion method could be an alternative to replacing conventional wet digestion method.

Cytotoxic Nitric oxide (NO) overproduced by inducible NO Synthase (iNOS or NOS2), which was induced in inflammatory reactions and immune responses directly or indirectly affects the functions as host defense and can cause normal tissue damage. Microarray analysis was performed to identify gene profiles of both NO-dependent and -independent transcripts in RAW 264.7 macrophages that use selective NOS2 inhibitors aminoguanidine ($100\;{\mu}M$) and L-canavanine (1 mM). A total of 3,297 genes were identified that were up- or down-regulated significantly over 2-fold in lipopolysaccharide (LPS)-treated macrophages. NO-dependency was determined in the expressed total gene profiles and also within inflammatory conditions-related functional categories. Out of all the gene profiles, 1711 genes affected NO-dependently and -independently in 567 genes. In the categories of inflammatory conditions, transcripts of 16 genes (Pomp, C8a, Ifih1, Irak1, Txnrd1, Ptafr, Scube1, Cd8a, Gpx4, Ltb, Fasl, Igk-V21-9, Vac14, Mbl1, C1r and Tlr6) and 29 geneas (IL-1beta, Mpa2l, IFN activated genes and Chemokine ligands) affected NO-dependently and -independently, respectively. This NO dependency can be applied to inflammatory reaction-related functional classifications, such as cell migration, chemotaxis, cytokine, Jak/STAT signaling pathway, and MAPK signaling pathway. Our results suggest that LPS-induced gene transcripts in inflammation or infection can be classified into physiological and toxic effects by their dependency on the NOS2-mediated NO release.

Biogas plant with anaerobic digestion is receiving high attention as a facility for both livestock waste treatment and electric power generation. Objective of this study was to perform life cycle assessment (LCA) of a biogas plant which incorporates swine and food waste (7:3) as source materials for biogas production. In addition, the biogas production process was compared with the prevalent composting method as a reference in the aspects of green house gas (GHG) reduction potential and environmental impact. The biogas method was capable of reducing 52 kg $CO_2$ eq. emission per ton of swine/food waste, but the composting process was estimated to emit 268 kg $CO_2$ eq. into air. The biogas method was evaluated as more beneficial to the environment by mitigating the impact on abiotic depletion potential (ADP), global warming potential (GWP), ozone depletion potential (ODP), eutrophication potential (EP), and photochemical ozone creation potential (POCP), but not to acidification potential (AP).

Objectives: Network pharmacology is an analysis method that explores drug-centered efficacy and mechanism by constructing a compound-target-disease network based on system biology, and is attracting attention as a methodology for studying herbal medicine that has the characteristics for multi-compound therapeutics. Thus, we investigated the potential functions and pathways of Myrrha on Allergic Rhinitis (AR) via network pharmacology analysis and molecular docking. Methods: Using public databases and PubChem database, compounds of Myrrha and their target genes were collected. The putative target genes of Myrrha and known target genes of AR were compared and found the correlation. Then, the network was constructed using STRING database, and functional enrichment analysis was conducted based on the Gene Ontology (GO) Biological process and Kyoto Encyclopedia of Genes and Genomes (KEGG) Pathways. Binding-Docking stimulation was performed using CB-Dock. Results: The result showed that total 3 compounds and 55 related genes were gathered from Myrrha. 33 genes were interacted with AR gene set, suggesting that the effects of Myrrha are closely related to AR. Target genes of Myrrha are considerably associated with various pathways including 'Fc epsilon RI signaling pathway' and 'JAK-STAT signaling pathway'. As a result of blinding docking, AKT1, which is involved in both mechanisms, had high binding energies for abietic acid and dehydroabietic acid, which are components of Myrrha. Conclusion: Through a network pharmacological method, Myrrha was predicted to have high relevance with AR by regulating AKT1. This study could be used as a basis for studying therapeutic effects of Myrrha on AR.
