However, its exact mechanism of action is still unclear and has been primarily associated with its effects on COX enzymes and serotonergic pathways. Till date, the immunological mechanisms affected by APAP has gained only inadequate attention. A distinct group of immune cells called Group 2 Innate Lymphoid Cells (ILC2s) are known to play an important role in type 2 cytokine-mediated immunity and their regulatory dysfunction is associated with numerous type 2 pathologies, such as allergy. Conversely, another class of recently characterized Innate Lymphoid Cells called Innate Regulatory Cells (ILCregs) suppress the activation of ILC2s. Maintaining a balance between ILC2s and ILCregs is vital for achieving a well-controlled immune response and tissue homeostasis. Recent studies have highlighted the critical role of prostaglandin D2 (PGD2) in the maturation and development of ILC2 functions. Since APAP also suppresses PGD2 synthesis, it was speculated that APAP treatment could reduce the number of ILC2s while potentially increasing the number of ILCregs. To investigate this hypothesis, here, we administered therapeutic doses of APAP to OVA-sensitized mice, a well-established model of type 2 pathological inflammation. The mice received oral doses of 200 mg/kg body wt. of APAP twice weekly, along with weekly OVA sensitizations for six weeks. The mice were sacrificed at different time points (days 14, 28 and 42) to assess the kinetics of ILC2s, ILCregs and immunoglobulins (IgE and IgG1). The results demonstrated that APAP treatment effectively suppressed OVA-induced ILC2s while significantly increasing the number of IL-10+ ILCregs. APAP exposure also led to decreased levels of serum PGD2, OVA-specific IgE and IgG1, and enhanced the level of IL-10 in OVA sensitized mice. Moreover, OVA sensitized mice treated with APAP did not develop pathological changes in spleen, when compared to OVA sensitized mice. Additionally, APAP treatment did not cause any adverse effects on mice liver in treatment groups. These preliminary findings suggest that APAP exhibits the capacity to modulate type 2 immune responses by suppressing ILC2s and inducing the expansion of IL-10+ ILCregs.","PeriodicalId":13290,"journal":{"name":"Indian journal of experimental biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135200803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, uncontrolled application of toxic pesticides/herbicides, particularly organophosphorus and sulfonylurea, has resulted in increased mortality and morbidity worldwide. The present study reports the neurotoxic effect of herbicides Excel Mera 71 and Almix based on brain histopathology of the Asian stinging fish, Heteropneustes fossilis (Bloch). Herbicides, Excel Mera 71 (17.2 mg/L) and Almix (66.67 mg/L) were administered to fish for 30 days. Study showed several endpoints in optic tectum with varying degree. Spongiosis, binucleated nuclei, congestion, necrosis, enlarged pyramidal cells (EPC), neuronal degeneration, vacuolization, gliosis, aberrant horizontal cell orientation and granular cells were prominent pathological symptoms in optic tectum in Excel Mera 71 and Almix-treated H. fossilis. Among the six layers, SPV (stratum periventriculare) and SAC (stratum album centrale) layer were maximally impacted by herbicide exposure. Appearance of neural necrosis, gliosis, vacuolization and loss of Nissl substances, collectively called neurotoxicity indicators, were very prominent under herbicides treatment. Higher prevalence of these lesions under Excel Mera 71 indicated that this herbicide has higher neurotoxic potential than Almix. Additionally, mean assessment value (MAV) indicated highest pathological lesions in Excel Mera 71 (4.06 ± 0.02), followed by Almix (3.28 ± 0.10) compared with control fish (0.09 ± 0.04). Collectively, these alterations indicated that both herbicides caused adverse effects on brain metabolism including sensory modalities, visual appearances, and motor coordination. Accordingly, brain optic tectum pathological changes can be utilized as biomarker of neurotoxicity evaluating of environmental toxicants.","PeriodicalId":13290,"journal":{"name":"Indian journal of experimental biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135200147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review is focused on the production of different biorefinery products and miscellaneous products from PL waste. The high cellulose content in PL makes it a potential feedstock for the production of different biorefinery products like bioethanol, oligosaccharides, nitrocellulose, and humic acid apart from this, waste is also useful for the production of different products like pineapple leaf fibres, fake eyelashes, organic leather, pulp and paper. Although the opportunities, future perspectives, and challenges concerning PL waste utilization to value-added goods were also addressed. It has been demonstrated that pineapple waste conversions lower waste creation, and the products produced by the conversion would promote the ‘waste-to-wealth’ notion.","PeriodicalId":13290,"journal":{"name":"Indian journal of experimental biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135200658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the L-asparaginase enzyme in its free state is unstable and has reduced half-life period with numerous side effects. Here, as a green synthesis approach, we have tried a nanocarrier to reduce its side effects and thereby the environmental pollution and toxicity. We used leaf extract of Mesosphaerum suaveolens (L.) Kuntze, commonly called Pignut, Wild spikenard or Horsehound, to produce a Mg-ZnO nanocomposite, which has antitumor activity by arresting the cell cycle of tumour cells. To the synthesized nanocomposite, extracted L-asparaginase enzyme from Aspergillus terreus was impregnated. The presence of ZnO helps to preserve the biological activity of immobilized L-asparaginase along with MgO making the nanocarrier biocompatible and biodegradable. This helps in increasing the stability and anticancer property of the L-asparaginase. The enzyme-impregnated nanobiocomposite was characterized using UV-Vis spectroscopy which ensured the existence of the Asp-Mg-ZnO in the nanobiocomposite. The presence of functional group and the crystallinity nature of the nanobiocomposite were studied using FT-IR and XRD, respectively. The morphological structure and elemental composition of the nanobiocomposite were determined using the SEM-EDAX. The anticancer activity of the synthesized Asp-Mg-ZnO nanobiocomposite was determined using the MTT assay, which helped to determine the viability and proliferation capacity of the cancer cells.","PeriodicalId":13290,"journal":{"name":"Indian journal of experimental biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135199169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Saponins are glycosides of triterpenes and steroids known for their antivenom properties. The soap bark tree or Quillaya, Quillaja saponaria Molina represents the major resource of saponins for commercial applications. Here, we investigated the antivenom property of silver nanoparticle mediated saponins (AgNP-SP) from the Q. saponaria bark extract. AgNP-SP was prepared conducive to optimal temperature, pH of extract and concentration of AgNO3. UV-VIS, FT-IR, XRD, TEM and SEM interpretations were devised to characterize AgNP-SP. AgNP-SP was tested for its efficacy to neutralize venom lethality and increase in myotoxicity biomarkers (LDH) in animal models. AgNP-SP was synthesized optimally at a concentration of 50 mg/mL, extract (pH 6.8) and temperature (80°C) with AgNO3 (1 mM). The colour change and synthesis of AgNP-SP was examined by UV–Vis analysis at 430 nm. TEM studies showed the size for AgNP-SP to be 74.4 nm. FT-IR analysis showed peaks of AgNP-SP at 3422 cm−1 and 2926 (O–H stretching), 2358 cm−1 (O=C=O stretching), 1616 cm−1 (C=C stretching), 1097 cm−1 (C–F stretching), 813 cm−1 (C–CL stretching) and 651 cm−1 (C–Br stretching). The EDAX established the purity of the AgNP-SP. The biosynthesized AgNP-SP could significantly neutralize Vipera russelli venom (VRV) mediated elevation of biomarkers lactate dehydrogenase (LDH), serum glutamate pyruvate transaminase (SGPT) serum glutamic-oxaloacetic transaminase (SGOT), serum creatinine and serum uric acid. The present study, thus promulgates the therapeutic potential of silver nanoparticle mediated saponins (AgNP-SP) in ameliorating the biochemical and pharmacological effect of haemotoxic snake venom in animal models.","PeriodicalId":13290,"journal":{"name":"Indian journal of experimental biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135200230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
