Abstract
Chemically engineered PLGA nanospheres are one of the emerging technologies for treating neurodegenerative disorders by inhibiting Catechol-O-methyltransferase (COMT). PLGA-MATPM nanospheres were chemically synthesized using PLGA and MATPM (N-allyl-N-(3-(m-tolyloxy)propyl) methioninate). The tailored PLGA nanospheres induce dose-dependent COMT inhibition in competitive kinetic mode. The interactions between COMT and PLGA nanosphere are explained by spectroscopic and molecular dynamics analysis. PLGA-MATPM NPs suppressed the growth of neuroblastoma cells due to the neurodegenerative toxicity of MPTP induction, demonstrating its potency as a cure for neurological disorders. PLGA-MATPM NPs cross the blood-brain barrier more effectively than those in the blood. Furthermore, PLGA nanospheres showed the most neurodegenerative recovery against MPTP-induced C57BL/6 mice. Using magnetic resonance imaging (MRI), it was validated for quality images of cerebral blood flow (CBF).

Abstract
In this study, the liquid chromatographic (LC) parameters were optimized using response surface methodology (RSM) as a novel approach to achieve optimal separation of six vitamers of vitamin D and K during simultaneous estimation. Analytes were separated using an Accucore C18 column (50 x 4.6 mm, 2.6 µm), 0.1% aqueous formic acid (pH = 3.5), and methanol as mobile phase components. The Box-Behnken design (BBD) predicted the best combination of the selected critical quality attributes such as organic solvent composition in the mobile phase (90%), mobile phase flow rate (0.42 mL/min), and column oven temperature (40oC). Multiple regression analysis was used to fit the experimental data from 17 sample runs to a second-order polynomial equation. The adjusted coefficient of determination (R2) for three desired responses were 0.983 (retention time of K3 = R1), 0.988 (resolution between D2 and D3 = R2), and 0.992 (retention time of K2-7 = R3), all with significant probability values (p<0.0001), indicating a high significance for the regression model. Q-ToF/MS detection was interfaced with an electrospray combined ionization source. The optimized detection parameters delivered specific, sensitive, linear, accurate, precise, and robust quantification of all six analytes in the tablet dosage form.

Abstract
Focal cortical dysplasia (FCD) is an inborn anomaly in brain growth and morphological deformation in lesions of the brain which induces focal seizures. Neurosurgical therapies were performed for the detection of FCD. Furthermore, it can be overcome through the presurgical evaluation of epilepsy. The surgical result is attained basically through the output of the presurgical output. In preprocessing the process of increasing true positives with the decrease in false negatives occurs which results in an effective outcome. MRI (Magnetic Resonance Imaging) outputs are efficient to predict the FCD lesions through T1- MPRAGE and T2- FLAIR efficient output can be obtained. In our proposed work we extract the S2 features through the testing of T1, T2 images. Using RNN-LSTM (Recurrent neural network-Long short-term memory) test images were trained and the FCD lesions were segmented. The output of our work is compared with the proposed work yields better results compared to the existing system such as artificial neural network (ANN), support vector machine (SVM), and convolution neural network (CNN). This approach obtained an accuracy rate of 0.195% (ANN), 0.20% (SVM), 0.14% (CNN), specificity rate of 0.23% (ANN), 0.15% (SVM), 0.13% (CNN) and sensitivity rate of 0.22% (ANN), 0.14% (SVM), 0.08% (CNN) respectively in comparison with RNN-LSTM.

Abstract
In the current scenario, used paper cups are disposed of without any proper treatment, thereby damaging the environment. Hence, the vermicomposting technique is preferred for managing these wastes. The ability of bacterial strains on cellulase enzyme (Endoglucanase, exoglucanase and β-glucosidase) production at altered pH and temperatures were focused in this study. Among nine bacterial strains Acinetobacter baumannii was found to have high enzyme activity. HPLC analysis confirms that about 45% of cellulose degradation occurred due to the action of bacterial consortia at 37 °C with pH 7. The overall period required for degradation takes only three months with the help of bacterial consortia while comparing to our previous study, which takes six months. The insilico study on three cellulose-degrading enzymes sequence were retrieved from NCBI, and analysed for multiple sequence alignment and phylogenetic tree construction. From the analysis, the endoglucanase SVK46152 (Acinetobacter baumannii) sequence got docked with cellopentaose with a high score value -11.07. Thereby we confirm that organism Acinetobacter baumannii was effective in paper cup degradation.

Abstract
A novel and selective electrochemical sensing of nicotine is studied using copper tungstate decorated reduced graphene oxide nanocomposite (CuWO4/rGO) nafion (Nf) immobilized GC electrode (GCE). The CuWO4/rGO nanocomposite is synthesized using sonication method and characterized by HR-TEM (High resolution transmission electron microscopy), SEM (Scanning electron microscopy), FT-IR (Fourier transform infrared spectroscopy), SAED (Selected area of electron diffraction pattern), XRD (X-ray diffraction), Raman spectroscopy, Thermo gravimetric analysis (TGA) and EDX (Energy dispersive X-ray diffraction) techniques. The CuWO4/rGO/Nf immobilized GCE shows better electrocatalytic response for the detection of nicotine as compared to bare GCE. A better selectivity and sensitivity is achieved using CuWO4/rGO/Nf immobilized GCE to detect 0.1 µM nicotine in the presence of 100-fold excess concentrations of different interferents. The present CuWO4/rGO/Nf immobilized GCE electrochemical sensor exhibits an ample range of sensing from 0.1 µM to 0.9 µM and the low detection limit is found to be 0.035 µM (S/N = 3). Comparable results are achieved for the determination of nicotine in various real samples such as cigarettes (Gold flake and Wills) and urine samples with improved recoveries.
