    Abstract Context: A subset of polycystic ovary syndrome (PCOS) individuals also have type 2 diabetes (T2D); an unmet need to identify this subgroup exists.
    Objective: We looked at the potential role of serum chemerin, a proinflammatory adipokine, in identifying dysglycemic PCOS.
    Methods: A total of 93 PCOS and 33 healthy controls were classified, based on fasting and 2-hour plasma glucose levels (2hPGPG) and glycated hemoglobin A
    Results: Metabolic syndrome was present in 9.7% (National Cholesterol Education Program) of PCOS. Waist circumference, body fat (%), 2hPGPG, and HbA
    Conclusion: Elevated serum chemerin levels reliably identify PCOS individuals with dysglycemia. Further, longitudinal studies with larger samples are required to confirm this association.

    Abstract Purpose: Diabetic retinopathy (DR), the leading cause of blindness among working adults, is an urgent public health problem as diabetes mellitus (DM) is increasing at an alarming rate. Hyperglycemia-induced endothelial dysfunction is the principal contributing factor leading to the development of microangiopathy. Altered levels of microRNA (miR), the negative regulator of protein-coding genes, have been observed and considered to be markers for DR. Present study aimed to find out whether miR levels in plasma could be effective biomarkers to differentiate between type 2 diabetes mellitus (T2DM) with non-proliferative retinopathy (NPDR) from T2DM with no-DR (DNR).
    Methods: We recruited 50 T2DM subjects comprising 31 NPDR and 19 DNR individuals. Surrogate markers of systemic oxidative stress and vascular endothelial growth factor (VEGF) were measured in plasma. Levels of miR-126 and miR-132 were determined in plasma and vitreous fluid using real-time PCR.
    Results: We observed that levels of miR-126 and miR-132 were decreased in NPDR subjects in comparison to DNR. Plasma levels of miRs were inversely correlated with secreted levels of VEGF and oxidative stress marker. The levels of these miRs showed discriminating ability between NPDR and DNR.
    Conclusion: Circulating miRs 126 and 132 in plasma or vitreous may serve as biomarkers for early diabetic retinopathy risk prediction, provided validated in a larger cohort and other forms of retinal vasculopathy or retinopathy in the future.

    Abstract Altered expression of protein coding gene (PCG) and long non-coding RNA (lncRNA) have been identified in SARS-CoV-2 infected cells and tissues from COVID-19 patients. The functional role and mechanism (s) of transcriptional regulation of deregulated genes in COVID-19 remain largely unknown. In the present communication, reanalyzing publicly available gene expression data, we observed that 66 lncRNA and 5491 PCG were deregulated in more than one experimental condition. Combining our earlier published results and using different publicly available resources, it was observed that 72 deregulated lncRNA interacted with 3228 genes/proteins. Many targets of deregulated lncRNA could also interact with SARS-CoV-2 coded proteins, modulated by IFN treatment and identified in CRISPR screening to modulate SARS-CoV-2 infection. The majority of the deregulated lncRNA and PCG were targets of at least one of the transcription factors (TFs), interferon responsive factors (IRFs), signal transducer, and activator of transcription (STATs), NFκB, MYC, and RELA/p65. Deregulated 1069 PCG was joint targets of lncRNA and TF. These joint targets are significantly enriched with pathways relevant for SARS-CoV-2 infection indicating that joint regulation of PCG could be one of the mechanisms for deregulation. Over all this manuscript showed possible involvement of lncRNA and mechanisms of deregulation of PCG in the pathogenesis of COVID-19.

    Abstract Hyaluronic acid (HA)-CD44 pathway showed association with several malignancies. The natural polyphenols Plumbagin, Pongapin and Karanjin showed anti-cancer activities in different tumors including cervical carcinoma. To understand their mechanism of anti-cancer activity, the effect of the compounds on HA-CD44 pathway was analyzed in cervical cancer cell line HeLa. The mRNA expression of three different isoforms of CD44 i.e., CD44s, CD44v3, and CD44v6, was differentially downregulated by the compounds. This was validated by Western blot and immunocytochemical analysis of CD44s.The low molecular weight HA (LMW-HA) showed growth promoting activity in HeLa at low concentration, whereas high molecular weight HA (HMW-HA) had no such effect. The compounds could preferentially downregulate the LMW-HA level in HeLa, as evident in the cell as well as in the cell-free conditioned medium. Concentration-dependent upregulation of HA synthase-2 (HAS2) was seen in the cell by the compounds, whereas differential downregulation of hyalurinidases 1-4 (HYAL 1-4), predominantly HYAL1, were seen. The compounds could also downregulate the downstream target of the pathway p-AKT (T-308) in concentration-dependent manner. Thus, the compounds could attenuate the HA-CD44 pathway in HeLa cell to restrict the tumor growth.

    Abstract Yeasts of Rhodotorula genus have been reported to show endophytic colonization in different plants. Some of the Rhodotorula species are found to exhibit plant growth promoting activities and also have been reported to protect plants against invading pathogens. A yeast strain closely related to Rhodotorula mucilaginosa was isolated from the endosphere of Typha angustifolia collected from a Uranium mine. A microarray analysis was performed to investigate the early changes in rice shoot transcripts in response to this yeast (R. mucilaginosa JGTA-S1). Transcriptional changes were monitored in 6 h and 24 h treated rice plant shoots as compared to 0 h control. The microarray data has been submitted to the NCBI GEO repository under the accession number of GSE64321.

    Abstract Background & objectives: Medicinal plants like Swertia chirata are rich sources of different xanthones. This study was aimed to assess the cytotoxic potential of four most abundant xanthones present in S. chirata both in vivo and in vitro in Ehrlich ascites carcinoma (EAC), a mouse transplantable breast carcinoma cell line and two human breast carcinoma cell lines (MCF-7 and MDA-MB-231).
    Methods: Four xanthones derived from S. chirata namely 1-hydroxy-3,7,8-trimethoxyxanthone (XA), 1,8-dihydroxy-3,5-dimethoxyxanthone (XB), 1-hydroxy-3,5,8-trimethoxyxanthone (XC) and 1,5,8-trihydroxy-3-methoxyxanthone (XD) were used for determination of sub-lethal dose on the cell lines EAC, MCF-7, MDA-MB-231 and verified toxicity of sub-lethal dose on normal murine fibroblast cells. Cytotoxicity was measured in vivo and survivability of mice was plotted accordingly. Therapeutic efficacy of XD was evaluated both in vivo and in vitro by determination of lipid peroxidation (LPO), reactive oxygen species (ROS) generation and by quantitating the enzyme status (GSH, catalase, superoxide dismutase) in treated and untreated samples. DNA damage was evaluated using comet and DNA fragmentation assays. Furthermore, apoptotic effect was analyzed by flow cytometry and validated by TUNEL assay and Western blotting.
    Results: Among all the xanthones tested XD showed IC
    Interpretation & conclusions: Our experimental data indicate that XD may potentially act as a chemotherapeutic agent by enhancing ROS in breast cancer cells thereby leading to apoptosis.

    Abstract Background: The Anticancer property of Swertia chirata has been well established. It forms a rich source of compounds to which its anticancer property can be attributed, among the compounds found in S. chirata xanthones form an important group. Among the most abundant xanthones found in S. chirata, 1,5,8-trihydroxy-3-methoxy xanthone (TMX) was found to be most effective. As metastasis is the underlying cause of most cancer-related deaths, in this study, we evaluated the anti-metastatic potential of TMX against adenocarcinoma both in vivo and in vitro.
    Materials and methods: In vivo anti-metastatic potential was proved by histological evidence of different organs, giemsa staining of bone marrow, subcutaneous re-injection of the aberrant bone marrow cells into the right flank of the mice to observe the formation of tumors and analyzing the markers related to metastasis by immunohistochemistry (IHC) and western blot. In vitro validation of anti-metastatic potential was carried out against human breast adenocarcinoma cell line MCF-7 by primarily analyzing the migratory property of cells through scratch wound healing assay and the ability of cells to form colonies. The re-validation part was performed by western blot of markers related to metastasis and real-time analysis of EMT related markers.
    Results: In vivo, TMX treatment restricted metastasis of EAC induced solid tumor to liver, lung, bone marrow, and validation of this finding was achieved by down regulation of metastatic and EMT markers.  In vitro, TMX treatment restricted migratory and colony forming ability of MCF-7 cells by down regulating metastatic and EMT markers.
    Conclusion: It was proved from our study that TMX treatment successfully reduced the metastatic potential of EAC induced solid tumor, with in vitro validation TMX on the MCF-7 cell line.

    Abstract Background & objectives: Medicinal plants like Swertia chirata are rich sources of different xanthones. This study was aimed to assess the cytotoxic potential of four most abundant xanthones present in S. chirata both in vivo and in vitro in Ehrlich ascites carcinoma (EAC), a mouse transplantable breast carcinoma cell line and two human breast carcinoma cell lines (MCF-7 and MDA-MB-231). Methods: Four xanthones derived from S. chirata namely 1-hydroxy-3,7,8-trimethoxyxanthone (XA), 1,8-dihydroxy-3,5-dimethoxyxanthone (XB), 1-hydroxy-3,5,8-trimethoxyxanthone (XC) and 1,5,8-trihydroxy-3-methoxyxanthone (XD) were used for determination of sub-lethal dose on the cell lines EAC, MCF-7, MDA-MB-231 and verified toxicity of sub-lethal dose on normal murine fibroblast cells.

DNA damage was evaluated using comet and DNA fragmentation assays. Furthermore, apoptotic effect was analyzed by flow cytometry and validated by TUNEL assay and Western blotting. Results: Among all the xanthones tested XD showed IC50at the lowest dose, and normal cells were unaffected at this dose. Survivability of mice increased significantly when treated with XD compared to other xanthones and cisplatin. Significantly increased ROS and LPO were found in cancer cells as a result of XD treatment which was unaltered in normal cell line. XD induced DNA damage and apoptosis in cancer cell lines. Interpretation & conclusions: Our experimental data indicate that XD may potentially act as a chemotherapeutic agent by enhancing ROS in breast cancer cells thereby leading to apoptosis.

    Abstract Background and objectives: Various existing non-antiviral drugs are being used to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection based mostly on existing data from previous coronavirus outbreaks. Ivermectin is one of such agents being widely used to treat early-stage of COVID-19. This study evaluated the outcome of ivermectin treated mild to moderate COVID-19 cases compared to usual care. Methods: This open-label randomised controlled study was conducted at a sub-district (Upazila) health complex from 1st May 2020 to the end of July 2020. Consecutive RT-PCR positive eligible COVID-19 patients were randomised into control and intervention arms. In the intervention arm, ivermectin 200 micrograms/kg single dose was administered orally in addition to usual care and was followed up till recovery. Repeat RT-PCR was done on day ten since the first positive result. The end point with regard to treatment outcome was time required for the resolution of symptoms from the onset of the symptoms and following enrollement in the study. Results: A total of 62 mild to moderate COVID-19 patients were enrolled in the study. There were 30 patients in the control arm and 32 patients in the intervention arm. Total recovery time from the onset of symptoms to complete resolution of symptoms of the patients in the intervention arm was 10.09 ± 3.236 days, compared to 11.50 ± 5.32 days in the control arm (95% CI -0.860,3.627, p>. 05) and was not significantly different. The mean recovery time after enrolment in the intervention arm was 5.31 ± 2.48 days, which also did not differ significantly from the control arm of 6.33 ± 4.23 days (95% CI – 0.766, 2.808, p> 0.05). Results of negative repeat RT- PCR were not significantly different between control and intervention arms (control 90% vs intervention 95%, p>.05). Conclusion: Ivermectin had no beneficial effect on the disease course over usual care in mild to moderate COVID-19 cases. IMC J Med Sci 2020; 14(2): 002. EPub date: 03 September 2020. OPEN ...
