    Abstract In this work, a new doxycycline stabilized silver nanocatalyst (Dox-Ag (0) NPs) was synthesized in aqueous solution (green method) by one-pot simple synthetic method for the ultra-fast catalytic degradation of ibuprofen and paracetamol. The formation of the Dox-Ag (0) NPs was monitored using UV–Vis absorption spectroscopy which confirmed the formation of Dox-Ag (0) NPs by exciting the typical surface plasmon absorption maxima at 404 nm. Transmission electron microscopy (TEM) confirmed the spherical morphology and monodispersed Dox-Ag (0) NPs with particle size 6.87 ± 2.2 nm. The newly synthesized Dox-Ag (0) NPs had an excellent catalytic activity as a catalyst for the 100% degradation of ibuprofen and paracetamol, which was carried out in 60 s. The antimicrobial activities of this catalyst were also evaluated against Gram-negative bacteria Mycoplasma hominis, Escherichia coli, Pseudomonas aeruginosa and Gram-positive bacteria Staphylococcus aureus, Micrococcus flavus and Micrococcus luteus by the disk diffusion method. Whereas standard antibiotic showed no zone of inhibition, the Dox-Ag (0) NPs showed good inhibition zone. The antimicrobial results therefore reveal that newly synthesized Dox-Ag (0) NPs had a tremendous catalytic and antimicrobial activity as a catalyst. They were recovered easily from reaction medium and reused with enhanced catalytic potential seven times. The current findings are equally extendable for safeguarding the aquatic environment against the pollution caused by drugs and microbial activity via a facile, highly economical, rapid and efficient reduction/degradation method based on the catalytic potential of Dox-Ag (0) NPs.

    Abstract Drug induced liver injury (DILI) is a global issue and acetaminophen (APAP) is considered as the main cause of this. Due to increasing incidents of DILI, current study attempted to investigate an alternative but better role of terazosin (alpha-adrenergic blocker) in APAP-induced acute liver injury in an animal model using New Zealand rabbits. APAP (1 g/kg of body weight) was given to New Zealand rabbits either with or without terazosin (0.5 mg/kg) and serum was collected after 4 h. Serum alanine transaminase (ALT), alkaline phosphatase (ALP) and ferritin level were determined to analyze the liver functioning of treated rabbits. Furthermore, total cholesterol (TC), total lipids (TL), high-density lipoproteins (HDL), low-density lipoprotein (LDL) and triglycerides (TG) levels were estimated to find any change in lipid profile of the treated animals. Moreover, the urea and creatinine levels assayed the actual renal functionality. To identify any modification in gene expression, qPCR of cytochrome P2E1 (CYP2E1) was performed. Terazosin in combination with APAP enhanced liver functioning by reducing the levels of liver injury markers viz. ALP and ALT, while lipid profile was also lowered by down regulation of TC, TL, LDL and TG with enhanced HDL levels. It caused significant down regulation of expression level of CYP2E1. It is concluded that terazosin has better effects induced on the recovery of normal liver functioning, by improving the liver profile, lipid profile and renal functioning both at tissue and molecular levels.

    Abstract SYBR duplex real-time polymerase chain reaction (SDRT-PCR) with melting curve analysis was developed that can unite the reward of multiplex PCR with real-time PCR to recognize animal genes rapidly in feedstuffs. The method merges the use of bovine (Bos taurus) and poultry (Gallus gallus) specific primers that amplify small fragments (amplicons <200 base pairs) of the mitochondrial gene. Appropriate mixtures of bovine and poultry heat treated meat DNAs were used to develop the assay. Gene products of bovine and poultry were produced two distinct melting peaks simultaneously at 79.5 °C and 87.5 °C, respectively. Multiplex analysis of the reference feed samples showed that the detection limit of the assay was 0.001% for bovine and poultry species. Based upon the assay results it has been concluded that SDRT-PCR assay might be an efficient tool for the verification of species origin in feedstuffs.

    Abstract A hexaplex-conventional PCR assay was developed for identification of five meat and one plant species origins in foodstuffs simultaneously. The method merges the use of horse (Equus caballus), soybean (Glycine max), sheep (Ovis aries), poultry (Meleagris meleagris), pork (Sus scrofa), and cow (Bos taurus) specific primers that amplify fragments (horse; 85 bp, soybean; 100 bp, sheep; 119 bp, poultry; 183 bp, pork; 212 bp and cow; 271 bp) of the mitochondrial cyt b, lectin, 12S rRNA, 12S rRNA, ATPase subunit 6 genes and ATPase subunit 8 genes respectively, and a universal 18S rRNA primers that amplifies a 141 bp. Multiplex analysis of the reference food samples showed that detection limit of the hexaplex assay was 0.01% for each species. Taken together, all data indicated that this hexaplex PCR assay was a simple, fast, sensitive, specific, and cost-effective detection method for horse, soybean, sheep, poultry, pork and cow species in foodstuffs.

    Abstract In this review, we focused on the origins of the novel coronavirus (SARS-CoV-2), origin, pathogenesis, immune responses, genes and genetic variations, phylogenetic analyses, and potential therapeutic strategies to summarize approaches for developing broadly effective preventions and vaccines to cope COVID-19. Towards the end of 2019, SARS-CoV-2 has emerged in association with the SARS, later was named COVID-19 caused an environment of chaos worldwide and infected a massive number of lives. Since these epidemics or pandemics had spread to 210 countries and territories around the world and 2 international conveyances with 6,467,229 confirmed cases, including, 382,766 deaths, as of June 03, 2020 (https://www.worldometers.info/coronavirus/), hence the World Health Organization declared it as a global Public Health Emergency. There are no clinically approved vaccines or antiviral drugs available for either of new or old corona infections; thus, the development of effective therapeutic and preventive strategies that can be readily available to cope with these strains.

    Abstract A multiplex PCR assay was developed for rapid and reliable identification of bovine, ovine, caprine and fish species in feedstuffs simultaneously. The method merges the use of bovine, ovine, caprine and fish primers that amplify fragments (ovine; 119 bp, caprine; 142 bp, fish; 224 bp and bovine; 271 bp) of the mitochondrial t.glu gene forward and cyt b reverse, 12S rRNA, 12S rRNA, and ATPase subunit 8 genes respectively, and a universal 18S rRNA primers that amplifies a 99 bp from eukaryotic DNA. To evaluate the effect of heat treatment, a severe sterilization condition (133 °C at 300 kPa for 20 min) was applied. Multiplex analysis of the reference feedstuff samples showed that the detection limit of the assay was 0.01% for each species. Taken together, all data indicated that this multiplex PCR assay was a simple, rapid, sensitive, specific, and cost-effective detection method for bovine, ovine, caprine and fish species in feedstuffs.

    Abstract Acute Kidney Injury (AKI) is a common manifestation of COVID-19 and several cases have been reported in the setting of the high-risk APOL1 genotype (common genetic variants). This increases the likelihood that African American people with the high-risk genotype APOL1 are at increased risk for kidney disease in the COVID-19 environment. Single-nucleotide polymorphisms (SNPs) are found in various microRNAs (miRNAs) and target genes change the miRNA activity that leads to different diseases. Evidence has shown that SNPs increase/decrease the effectiveness of the interaction between miRNAs and disease-related target genes. The aim of this study is not only to identify miRSNPs on the APOL1 gene and SNPs in miRNA genes targeting 3'UTR but also to evaluate the effect of these gene variations in kidney patients and their association with SARS-COV-2 infection. In 3'UTR of the APOL1 gene, we detected 96 miRNA binding sites and 35 different SNPs with 10 different online software in the binding sites of the miRNA (in silico). Also we studied gene expression of patients and control samples by using qRT-PCR (in vitro). In silico study, the binding site of miR-6741-3p on APOL1 has two SNPs (rs1288875001, G > C; rs1452517383, A > C) on APOL1 3'UTR, and its genomic sequence is the same nucleotide as rs1288875001. Similarly, two other SNPs (rs1142591, T > A; rs376326225, G > A) were identified in the binding sites of miR-6741-3p at the first position. Here, the miRSNP (rs1288875001) in APOL1 3'UTR and SNP (rs376326225) in the miR-6741-3p genomic sequence are cross-matched in the same binding region.

Similarly, two other SNPs (rs1142591, T > A; rs376326225, G > A) were identified in the binding sites of miR-6741-3p at the first position. Here, the miRSNP (rs1288875001) in APOL1 3′UTR and SNP (rs376326225) in the miR-6741-3p genomic sequence are cross-matched in the same binding region. In vitro study, the relative expression levels were calculated by the 2⁻ΔΔCᵗ method & Mann–Whitney U test. The expression of APOL1 gene was different in chronic kidney patients along with COVID-19. By these results, APOL1 expression was found lower in patients than healthy (p < 0.05) in kidney patients along with COVID-19. In addition, miR-6741-3p targets many APOL1-related genes (TLR7, SLC6A19, IL-6,10,18, chemokine (C–C motif) ligand 5, SWT1, NFYB, BRF1, HES2, NFYB, MED12L, MAFG, GTF2H5, TRAF3, angiotensin II receptor-associated protein, PRSS23) by evaluating online software in the binding sites of the miR-6741-3p. miR-6741-3p has not previously shown any association with kidney diseases and SARS-COV-2 infection. It assures that APOL1 can have a significant consequence in kidney-associated diseases by different pathways. Henceforth, this study represents and demonstrates an effective association between miR-6741-3p and kidney diseases, i.e., collapsing glomerulopathy, chronic kidney disease (CKD), acute kidney injury (AKI), and tubulointerstitial lesions susceptibility to SARS-COV-2 infection via in silico and in vitro exploration and recommended to have better insight.
