Morphotaxometry and Ultratopography of Lytocestus haryanii n.sp. (Caryophyllidea: Lytocestidae) from the intestine of freshwater catfish Clarias batrachus Linnaeus 1758 (Siluriformes: Clariidae) of river Yamuna, Yamuna Nagar, Haryana, India

The present investigation deals with the first report of newer species of caryophyllid cestodes, Lytocestus haryanii n.sp. (Caryophyllidea: Lytocestidae) in the freshwater catfish, Clarias batrachus Linnaeus 1758 (Siluriformes: Clariidae) of river Yamuna from Yamuna Nagar, Haryana, India from July 2018 to June 2020. These helminthes are the most common cestodes (endoparasites) among the fishes of fresh water, brackish water, and marine habitat worldwide.  The recovered newer worms were processed through the standardized protocol for the microscopic observations and morphometry, ultratopographic study through scanning electron microscopy, and anatomical analysis by histology using microtomy techniques followed by the double staining. The findings of the present worms were substantiated and compared with the earlier reported species of the same genera from different hosts shared the common group using advanced numerical taxonomy for the taxometric validation. The present proposed newer worms shared all the common characteristics which helped in the generic diagnosis and are closely related to the species collected from the same host species inhabiting different freshwater bodies. The worms comprised several striking contrasts in the combination of distinguishing characters of taxonomic significance in special reference to shape, size, orientation, distribution, and the dimension of the body (single proglottid), scolex, neck, testes, ovary, cirrus pouch, vitellaria, eggs, and excretory pore. Based on the striking morphological, taxometric, ultratopgraphic, and histological differences summarized here can, therefore, be used to propose the worm as a new species.

Antioxidant phytoconstituents from Onosma bracteata Wall. (Boraginaceae) ameliorate the CCl4 induced hepatic damage: in vivo study in male wistar rats

Onosma bracteata Wall. (Boraginaceae) is a highly valuable medicinal herb that is used for the treatment of fever, bronchitis, asthma, rheumatism, stomach irritation, and other inflammatory disorders. The present study aims to explore the hepatoprotective potential of ethanolic extract (Obeth) from O. bracteata aerial parts against carbon tetrachloride (CCl4) which causes hepatic damage in the male Wistar rats. Obeth showed effective radical quenching activity with an EC50 of 115.14 and 199.33 µg/mL in superoxide radical scavenging and lipid peroxidation analyses respectively along with plasmid DNA protective potential in plasmid nicking assay. The Obeth modulated mutagenicity of 2 Aminofluorine (2AF) in the pre-incubation mode of investigation (EC50 10.48 µg/0.1 mL/plate) in TA100 strain of Salmonella typhimurium. In in vivo studies, pretreatment of Obeth (50, 100, and 200 mg/kg) had the potential to normalize the biochemical markers aggravated by CCl4 (1mL/kg b.wt.) including liver antioxidative enzymes. Histopathological analysis also revealed the restoration of CCl4-induced liver histopathological alterations. Immunohistochemical studies showed that the treatment of Obeth downregulated the expression levels of p53 and cyclin D in hepatocytes. and downregulation in the Western blotting analysis revealed the downregulation of p-NF-kB, COX-2, and p53. HPLC data analysis showed the supremacy of major compounds namely, catechin, kaempferol, epicatechin, and Onosmin A in Obeth. The present investigation establishes the hepatoprotective and chemopreventive potential of O. bracteata against CCl4-induced hepatotoxicity via antioxidant defense system and modulation of the expression of proteins associated with the process of carcinogenesis in hepatic cells

Plastic Waste in India: overview, impact, and measures to mitigate: Review

India is one of the world’s large and fastest-growing economies. With the expanding development, the usage of plastic for anthropogenic activities has expanded many folds and India alone generated around 3.3 million metric tonnes of plastic in the financial year 2019. 79 percent of the plastic generated worldwide enters our land, water, and environment as waste; part of it also enters our bodies through the food chain. The industry in India states that 60 percent of what is generated is recycled and we had assumed that we had solved the problem of plastic waste by recycling, or burying it in landfills. But we were incorrect. Plastic garbage is omnipresent today. It is filling up our oceans and harming marine life and affecting all organisms in the food chain. With the development of economic growth of the country per capita consumption of plastic will only increase in the coming years and we will end up generating more plastic waste The review paper aimed to examine the major impact of plastic waste in India and how to reduce plastic consumption, considering measures such as phasing out or banning multilayered plastics that cannot be recycled, contemplating renewable raw materials, promoting the use of bioplastics, incentivizing the recycling business, and making the rules and guidelines for Extended Producer Responsibility (EPR) simple and enforceable

Antibiotic susceptibility profile and detection of plasmid-mediated quinolone resistant genes among extended spectrum b-lactamases (ESBL) producing uropathogens in women

Background/Aim: The most common bacterial diseases in women around the world are urinary tract infections. Aim of this study, was to evaluate the prevalence and current antibiotic resistance rate of uropathogens isolated from the female patients of a tertiary care hospital in Amritsar, Punjab, India. Methods: Samples were collected from patients showing urinary tract infection (UTI) symptoms and analysed using microscopy, dipstick test and urine culturing followed by identification and characterisation of to identify the uropathogens. Antibiotic susceptibility test and MIC were performed. Results: The results revealed that E coli (35.5 %) was the most prominent uropathogen followed by Klebsiella spp (21 %), Enterobacter spp (17 %), Acinetobacter (11 %), Enterococcus spp (6 %), Pseudomonas spp (4.5 %), coagulase negative Staphylococci (4 %), coagulase-positive Staphylococci (0.5 %) and Corynebacterium aurimucosum (0.5 %). The antibiotic susceptibility profile study reported eight isolates with multi-drug resistance properties. However, gentamicin, imipenem and meropenem were found to be the most effective antibiotics against the isolated uropathogens. All the extended spectrum β-lactamase (ESBL)-positive isolates possess the quinolone-resistant gene qnrB, while qnrA was absent. Conclusion: The current study revealed that for appropriate treatment, it is crucial to be aware of the epidemiological data regarding the disease and to begin any empirical antibiotic treatment

In-silico designing of a potent ligand molecule against PTEN (Phosphatase and tensin homolog) implicated in Breast Cancer

Breast cancer has been attributed to be the second most common malignancy in females worldwide after skin cancer associated with a significantly high mortality rate. Tumor suppressor genes have an indispensable role in maintaining genomic integrity as well as cell cycle regulation. Phosphatase and tensin homolog deleted on chromosome ten (PTEN) is one of the most frequently mutated human tumor suppressor genes, implicated in cell growth, survival, and suppressing tumor formation. As the tumor progresses to more advanced stages, genetic alterations tend to increase one such alteration is the mutation of the PTEN gene which is linked to programmed cell death and maintenance of cell cycle regulation. There is a syndrome known as Cowden syndrome associated with a high risk of breast cancer which is a result of an outcome of germline mutations in the PTEN gene. Loss of PTEN activity, either at the protein or genomic level, has been related to many primary and metastatic malignancies including breast cancer. This study focuses on developing a potential bioavailable ligand inhibitory molecule for PTEN, using a computer-aided drug design approach (CADD). A library of developed ligands consisting of 50 potential molecules was screened to find a potential candidate to be used for second generation drug development. Among them, LIG28 was adjudged as the most effective and potential PTEN inhibitor given its maximum binding affinity of ΔG -5.96Kcal/mole with a lower RMSD value. Carmer’s Rule of toxicity further revealed the compatibility and non-toxicity of the molecule. These observations underscore the importance of PTEN as a target in the development of tumorigenesis and the prognosis of breast cancer

Assessing the Migration of BPA and Phthalic Acid from Take-out Food Containers: Implications for Health and Environmental Sustainability in India

The research investigates the escalating consumption of take-out food in India and the associated health risks stemming from the extensive use of plastic packaging. Through a comprehensive nationwide online survey, the study delved into dietary preferences, frequency of take-out food consumption, delivery service timing, and the types of packaging commonly encountered by Indian consumers. To address these concerns, the research team developed an analytical method to detect Bisphenol A (BPA) and Phthalic acid migration from food-contact materials (FCMs) into various food simulants. The investigation revealed that prolonged exposure to elevated temperatures led to increased migration of BPA and Phthalic acid, particularly in polyethylene pouches using 3% acetic acid as a food simulant, with the highest concentrations observed after 45 minutes of exposure. Additionally, a microbial bioassay demonstrated the mutagenic potential of migrated plasticizers, showcasing significant effects in mammalian systems, particularly under metabolic activation. The study underscores the substantial health risks associated with plastic packaging in take-out food, emphasizing potential implications for consumer health and calling for more extensive research and considerations regarding food packaging materials

Targeting NSP-13 protein of SARS CoV-2 with selected natural compounds: An in-silico approach

SARS-CoV-2 swiftly spread in Wuhan, China, leading to a pandemic crisis worldwide. Genome sequence analysis of this virus revealed a close analogy with its closely related strains, SARS-COV and MERS-COV. In the case of SARS-CoV-2, Nonstructural protein 13 (NSP13), also known as helicase, has been identified as a target for reducing the severity of infection due to its high sequence conservation and essential role in viral replication. NSP13 helicase structure in SARS-CoV-2 differs only by one amino acid from the SARS-CoV helicase structure. Targeting NSP13 with natural compounds holds significant potential for developing safe and effective antiviral therapies utilizing advanced computational approaches. The properties of 8 different natural compounds, i.e. Imidazole, Pyrrole, Tropolone, Benzotriazole, Imidazodiazepine, Phenothiazine, Acridone and Bananin were screened by applying Lipinski’s rule of five, ADME (absorption, distribution, metabolism, and excretion) properties, and Radar plots to discover their drug efficacy at a target site, safety, and absorption. Docking studies confirmed Bananin with a binding affinity of -7 kcal/mol as a potential inhibitor of NSP13 of SARS-CoV-2 with better pharmacokinetics, drug likeliness, and oral bioavailability. Based on the in silico study, it is suggested that Bananin shows promising effects against NSP13 protein, forming a maximum number of hydrogen bonds exhibiting higher binding affinity. This stronger affinity indicates a stronger interaction between the compound and its target, potentially leading to enhanced biological activity and therapeutic efficacy. This novel study has unlocked the door for a prospective SARS-CoV-2 inhibition strategy and developing antiviral interventions targeting NSP13 based on molecular docking.

Prominent Classes of Antibiotics and their Mechanism of Resistance against Methicillin-Resistant Staphylococcus aureus

Methicillin-resistant Staphylococcus aureus (MRSA) is a prominent pathogenic, antibiotic-resistant microorganism that contains a variety of virulent characteristics having the capacity to develop tolerance to several major classes of antibiotics. The ongoing creation of clones enhances this potential, transforming S. aureus into an “Anti-Infective.” MRSA has started to rise as a Hospital-Acquired MRSA, but due to evolution, new strains of MRSA have been discovered throughout the past several years. The new strains of MRSA as Community-Acquired MRSA, and Livestock-Associated MRSA are infecting the patients despite preexisting medical conditions, being as susceptible to any treatment. The continuous expansion of MRSA is still ongoing. The main goal of this article is to improve reading comprehension of MRSA by studying the prominent classes of antibiotics and their mechanism of resistance which are now susceptible or getting susceptible to the MRSA
