Hypoxemia occurs due to the role of pro-inflammatory cytokines and coagulation factors. Several studies have shown that interferon (IFN)-γ, plasminogen activator inhibitor 1 (PAI-1) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) are biological markers that can be used to evaluate the severity and prognosis of the disease in severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection. This study was conducted to evaluate the association between IFN-γ, PAI-1, NT-proBNP and hypoxemia in COVID-19 patients.METHODS: This was a cross-sectional study of COVID-19 subjects with hypoxemia. Hypoxemia assessment was performed based on arterial blood gas analysis. IFN-γ and PAI-1 were measured with ELISA, while NT-proBNP levels were measured with Roche NT-proBNP.RESULTS: Fifty-five COVID-19 subjects with hypoxemia were observed. Thirty subjects experiencing moderate to severe hypoxemia and 25 with mild hypoxemia. Levels of IFN-γ, PAI-1, and NT-proBNP were higher in COVID-19 subjects with moderate to severe hypoxemia compared to those with mild hypoxemia (261.14 (121-348.60) pg/mL vs. 145.50 (59.90-348.60) pg/mL, p<0.001; 5.47 (3.50-8.50) pg/mL vs. 3.40 (2.20-9.30) pg/mL, p<0.001; 760 (112-34,066) pg/mL vs. 71 (48-364) pg/mL, p<0.001).CONCLUSION: Elevated levels of IFN-γ, PAI-1, and NT-proBNP are associated with hypoxemia in COVID-19 patients, suggesting that these markers may be useful in assessing hypoxemia in COVID-19 patients.KEYWORDS: IFN-γ, PAI-1, NT-proBNP, hypoxemia, COVID-19","PeriodicalId":22516,"journal":{"name":"The Indonesian Biomedical Journal","volume":"54 45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135884834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This resistance can be attributed to the anti-apoptotic protein survivin and the antioxidant MnSOD high expression. To overcome the resistance to doxorubicin (DOX), this study proposed the utilization of andrographolide (ANDRO), the primary bioactive compound in Andrographis paniculata leaves. The objective was to examine the role of andrographolide in regulating survivin, caspase-9, and caspase-3 gene expressions to reverse doxorubicin resistance in human BCSCs.METHODS: BCSCs were exposed to 0.1 µM DOX every two days or 50 µM rotenone (ROT) for 6 hours, subsequently supplemented with 0.3 mM ANDRO. Superoxide and peroxide levels were measured using DHE and DCFH-DA assay. The MnSOD, survivin, caspase-9, and caspase-3 mRNA expression levels were analyzed using qRT-PCR. Protein expressions were evaluated using Western blotting assay. MnSOD activity was determined using xanthine oxidase inhibition assay. The apoptotic cells were determined using Annexin-V/PI staining.RESULTS: This study indicated that the cytotoxic mechanisms of DOX, similar to ROT, in BCSCs were attributed to oxidative stress, as evidenced by an elevation in superoxide rather than peroxide levels, accompanied by a decrease in MnSOD activity. This study also highlighted that ANDRO reversed DOX resistance in BCSCs subjected to repeated DOX treatment by downregulating survivin and upregulating caspase-9 and caspase-3 mRNA expressions, thereby activating the intrinsic apoptotic pathway.CONCLUSION: This study provides insights into the role of ANDRO in modulating the expression of apoptotic genes, such as survivin, caspase-9, and caspase-3, to overcome DOX resistance in BCSCs.KEYWORDS: breast cancer, breast cancer stem cell, andrographolide, doxorubicin, oxidative stress, apoptosis","PeriodicalId":22516,"journal":{"name":"The Indonesian Biomedical Journal","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135884830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adipocytes were later treated with either hrsACE2 or losartan. The levels of ACE2 and inflammatory cytokines interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α were measured using enzyme linked immunosorbent assay (ELISA). ACE2 and S1 spike protein binding assays were also performed. RESULTS: ACE2, IL-6, and TNF-α levels were significantly increased in human adipocyte cells infected with SARS-Cov-2 but not IL-1β.

Both leptin, an adipose tissue-produced cytokine-like hormone, and adiponectin, a hormone secreted by adipose tissue, play roles in the progression of MetS. However, the presence of leptin and adiponectin is also assumed to be associated with cancer proliferation. Therefore, it is necessary to investigate the profile of leptin and adiponectin levels in MetS patients with malignancy and non-malignancy.METHODS: This was a cross-sectional study involving 80 MetS subjects with and without malignancy. Leptin and adiponectin levels of subjects were analyzed by using the enzyme-linked immunosorbent assay (ELISA) method.

This study aimed to determine the presence of blaCTXM-1, blaCTXM-9, blaTEM-1, and blaSHV-1 genes in ESBL-EC in wastewater from selected hospitals in Manila and Quezon City, the Philippines.METHODS: Influent and effluent in twelve hospital wastewater treatment plants were collected, screened for cefotaxime-resistant E. coli, and examined for the ESBL production through phenotypic characterization using conventional bacterial identification, disk diffusion method, and VITEK® 2 Compact system and genotypic identification of ESBL-EC blaCTXM-1, blaCTXM-9, blaTEM-1, blaSHV-1 genes using multiplex polymerase chain reaction (PCR).RESULTS: Conventional bacterial identification methods and the VITEK® 2 Compact system results showed that both influent and effluent samples were positive for ESBL-EC at 33.3% and 16.7%, respectively. Multiplex PCR results revealed that various E. coli isolates were of ESBL-EC blaCTXM-1, blaCTXM-9, and blaTEM-1 genes.

The proposed hypothesis for the pathogenesis of this disease has changed over time, from immune dysregulation theory and systemic circulating factors theory, to the growing recognition of podocytopathies’ role. The existance of podocytopathies is usually examined by using podocyte-derived microparticles (MPs), such as nephrin, podocin, and podocalyxin (PCX). Therefore in this study, the difference between nephrin, podocin, and PCX expressions in NS children and healthy children was investigated.METHODS: An observational cross-sectional study was conducted, involving 33 children with NS and 22 age-matched healthy children as controls. Urine samples were collected from each subject in the early morning, before being processed and incubated with antibodies to detect nephrin, podocin, and PCX. The processed samples were then analyzed with flow cytometer methods.RESULTS: NS subjects had significantly higher expression of all three urinary podocyte-derived MPs compared to the control subjetcs. Nephrin, podocin, and PCX showed good discrimination in NS subjects with the area under curve (AUC) of 0.895, 0.849, and 0.728, respectively.CONCLUSION: This study revealed the differential expression of podocyte proteins in NS subjects compared to healthy controls. This supports the role of podocytopathies in the pathogenesis of NS.
