The existence of neuroglia cells similar to vertebrate microglia and small mobile phagocytes and hemocytes were documented from ganglia of some invertebrate animal models like leech (H. medicinalis), insects (P. americana and D. melanogaster) and mollusca (M. edulis). Neuronal replacement and migration of immunocompetent cells (macrophage, microglia, ependymal cells etc.) after surgical lesions in CNS of non-mammals (fishes, reptiles and aves) are much restricted to specific neurogenic niches associated to the neural regeneration and migration of cells in invertebrates. Microglial presence is largely restricted in the optic tract of fish and amphibian ganglionic cells because they have a surprising capacity to regenerate their neurons after lesions. Hence the CNS of both invertebrates and vertebrates contain microglia like mononuclear phagocytes, ensheathing glia and reticular glia, which indicate about the evolutionary conserved innate immune response to maintain CNS development and health. But the presence and gradual changes in the structure and function of microglia and neuron-microglia relationship in the CNS along the phylogeny need to be focused thoroughly.","PeriodicalId":16984,"journal":{"name":"JOURNAL OF SCIENTIFIC RESEARCH","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89761475","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 Cu(II) ion produces complexes with a distorted square planar, according to UV–Vis and ESR spectroscopy studies. The antioxidant activity of these complexes has been determined. The cytotoxic potential of the complexes was also investigated in vitro. The complex 3f was found to have significant cytotoxicity against MCF-7. The DNA binding characteristics of copper(II) complexes were investigated. The findings indicate that the complexes interacted with the calf thymus (CT-DNA).

A. indica is a plant that grows in the southern Indian state of Tamil Nadu. It has medicinal characteristics and is used as a diuretic, anthelmintic, and respiratory disorders like bronchitis, asthma, and pneumonia. The present work is designed to investigate GC-MS. Thirty compounds are found in the leaf extract. The structure-based biological activities study supported the Pass online database findings from the current study support that the use of this plant compound responsible for the anticancer activity is based on structure-based drug development. Based on in-silico results, it was shown that the interactions of hydrogen bonds, binding affinity with JAK2 kinase inhibitors, tumor suppressor proteins pRB Retinoblastoma protein, and COX-2 target proteins were compared with known values.

A. tumefaciens strain LBA 4404 harboring the plant transformation plasmid pBinAR contains the Tc chitI gene and nptII gene as a selectable marker. The precultured leaflet (LL) explants were infected with A. tumefaciens containing Tc chitiI gene and cocultivated on SIM (MMS+10 mg/L BAP+1 mg/L NAA+2 mg/L AgNO3) for four days. After co-cultivation, these explants were transferred to selection medium (SIM+75 mg/L Kan+250 mg/L Cefotaxime). In T0 generation, 70 % of transformation efficiency was recorded. T1 generation derived from the primary transgenic (T0) events revealed a Mendelian inheritance pattern (3:1) for the Tc chit I transgene. T1 transgenic peanut plants were tested for resistance against C. arachidicola, C. personatum, and P. arachidis by infection with the microspores using detached leaf assay. The Tc chitI gene expressed in T1 transgenic plants have shown longer incubation, longer latent period, and lower infection frequencies than non-transformed (WT) plants. A significant negative correlation was recorded between chitinase activity and the frequency of infection to the C. arachidicola, C. personatum and P. arachidis pathogens.","PeriodicalId":16984,"journal":{"name":"JOURNAL OF SCIENTIFIC RESEARCH","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89315576","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 total phenolic concentration of D. zibethinus parts was determined spectrophotometrically after collection and extraction. The anti-inflammatory activity was estimated using a lipooxygenase assay. Total phenolic content measured in gallic acid equivalent (GAE) gave the highest levels of 6.88 ± 1.54, 23.32 ± 1.73, and 29.00 ± 3.43 mg GAE/g sample weight leaves stem bark, and root extracts, respectively. The plant extracts showed lower anti- lipooxygenase activity in leaves (IC50 µg/mL- 1.464) and stem bark (IC50 µg/mL- 1.203), but had significant activity in root (IC50 µg/mL- 1.400) compared to standard indomethacin (IC50 µg/mL- 1.660). The plant extract's declining order of anti- lipooxygenase activity follows the same trend with the phenolic contents, indicating that the extract's magnitude of anti- lipooxygenase activity is comparable with the quantity of phenolic compounds present in the extracts. Hence, the D. zibethinus extracts are a potential candidate for a plant-derived anti-inflammatory agent.","PeriodicalId":16984,"journal":{"name":"JOURNAL OF SCIENTIFIC RESEARCH","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87134273","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}

Automatic video monitoring produces massive amounts of data that need human examination at some point. The primary emphasis is on reducing storage usage by compressing or eliminating superfluous frames without sacrificing real information. The current effort seeks to close the growing gap between the amounts of real data and the volume. Searching through key events in large video collections is time-consuming and tedious. In this paper, smart surveillance for various applications by using video summarization has been presented. A method for generating highlights has presented which pre-processes extracted Video Frames. Convolutional Neural Networks are then used to evaluate these highlighted frames. The proposed technique extracts and calculates characteristics utilized to generate summary movies. For training deep neural networks, cricket datasets have been used. Experimental results show that the proposed solution attains improved results than other advanced summarization methodologies. Experimental results show that the proposed video summarization method consistently generates high-quality reviews for all types of videos. The proposed video summarization method is easy to use, and it can also help extract highlights of cricket games with high accuracy.","PeriodicalId":16984,"journal":{"name":"JOURNAL OF SCIENTIFIC RESEARCH","volume":"132 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86815967","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}
