A set of copper(II) complexes (3a-i) comprises (16E)-N-(2-phenylquinolin-4(1H)-ylidene)-3-(phenlselanyl)pyridine-2-amine (L1-L3), (16E)-2,6-dimethyl-N-(2-phenylquinolin-4(1H)-ylidene)-5-(phenlselanyl)pyrimidine-4-amine (L4-L6), 16E)-N-(2-phenylquinolin-4(1H)-ylidene)-2-(phenylselanyl)H-imidazo[1,2-α]pyridine-3-amine (L7-L9) ligands were synthesised and characterised using spectroscopic techniques. The metal-to-ligand 1:1 stoichiometry of prepared copper complexes was confirmed by mass spectra. 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). In addition, the complexes were tested in vitro for antimicrobial activity against three Gram-negative bacteria, three Gram-positive bacteria, and three Fungi.

This paper deals with a mathematical model that represents non-Newtonian bile flow through a calculus duct under the influence of heat transfer with wall slip conditions. The peristaltic flow of bile is characterized by a generalized Carreau's model. An ordinate transformation is initiated to map the cosine geometry of the stone into a rectangular grid. It allows evaluation velocity, pressure distribution, flow rate, and reflux occurrence conditions, adopting the perturbation technique, the analytical solution obtained under various parameters, such as Knudsen number, amplitude ratio, Grashof number, Weissenberg number, and power index. These mathematical expressions are analyzed by plotting the graph in MATLAB R2018b software and observed that the axial velocity and the pressure gradient are strongly affected by heat and wall slip parameters.

The goal of this study is to look into the preliminary phytochemical and GC-MS analyses of a methanol extract of the leaves of Acalypha indica. Alkaloids, tannins, steroids, saponins, flavonoids, glycosides, and phenolic substances are found in leaf extract after phytochemical analysis. 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. It can be considered an increase in the possibility of conniving potential anticancer drugs as an anti-inflammatory agent.

In this study, an efficient Agrobacterium-mediated genetic transformation method followed by Tc chitiI gene for enhanced expression in peanut (Arachis hypogaea L.) cv ICG 7827 is reported. 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.

Durio zibethinus parts (leaves, stem bark, and root) used to treat malaria fever, vermifuge, diabetes, jaundice, inflammation, and oxidative stress management prompted the investigation of their total phenolic contents and anti-lipooxygenase activities. 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.

Recently, video surveillance technology has grown pervasive in many aspects of our lives. 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.

Microbial corrosion behavior of mild steel was studied by exposing mild steel coupons in Barr’s medium inoculated with sulfate-reducing bacteria (Desulfovibrio desulphuricans). During the investigation, a considerable loss in weight and deterioration of microstructure of mild steel coupons surface was observed. Coupons were further exposed to culture media containing different concentrations of metronidazole (MNZ) and 2- methylimidazole (MIZ) inhibitors. The corrosion behavior of mild steel was measured by weight loss, electrochemical studies, and SEM. Polarization studies indicated the mixed-type behavior of these inhibitors. MNZ and MIZ exhibited 82.23 and 78.30 % inhibition efficiencies, respectively, as revealed by polarization measurements. The results show that the inhibition efficiencies increased with inhibitor concentration. The surface analysis was performed by scanning electron microscopy (SEM).

Anaemia is a major public problem which is a matter of great concern for developing countries. In India, about 63% of women of aged between15 to 49 years are anaemic. Anaemia has severe consequences on the growing child and pregnant women. In this study, pregnant women in the age range 18- 45 years who consulted the Kurhani PHC of Muzaffarpur district for regular antenatal check-up were recruited. The participants were grouped on the basis of age. The blood samples from the recruited subjects were collected and a complete blood profile was done. The median age of the pregnant women participants was 25 years. Among 345 participants, 95% of the participants were of the age group 18 - 30 years. A total of 156 (45%) pregnant women were found anaemic with 72 (20.03%) having mild anaemia, 76 (22.87%) with moderate anaemia and 8 (2.31%) were severely anaemic. The findings from this study reveal the status of anaemia among the pregnant women of the local population; which will be used to design further epidemiological studies, and will pave the ways to explore the various aspects of anaemia in pregnancy; thus contribute to fulfill the mandate of the setup of Model Rural Health Research Unit at Kurhani-Muzaffarpur, Bihar.
