Electrochemical determination of ascorbic acid using sensitive and disposable methylene blue modified pencil graphite electrode.

In the present work, a convenient, efficient and disposable electrochemical sensor has been developed by electropolymerizing methylene blue (PMB) on the surface of a pencil graphite electrode (PGE), which facilitates the electrochemical analysis of an antioxidant l-Ascorbic Acid (AA). The structural characteristics of both the methylene blue modified pencil graphite electrode (PMB/PGE) and the bare pencil graphite electrode (BPGE) have been examined using scanning electron microscopy (SEM) in conjunction with energy-dispersive X-ray analysis (EDX). Additionally, the charge transfer behavior has been evaluated using the electron impedance spectroscopy (EIS).

Aim: The study aimed to detect and quantify bisphenol A (BPA) leaching in salivary samples of patients undergoing clear aligner therapy (CAT) using four different commercially available sheets.

Materials And Methodology: Four different commercially available clear aligners namely Monoflex®, Erkodur®, Leone®, and Duran® were delivered to 20 volunteers who were grouped into ( = 5) group A, group B, group C, and group D, respectively. Salivary samples were collected immediately before aligner insertion (day 0) and at day 1, day 5, and day 7 after aligner wear.

Impact of Crystallite Size and Phase Boundaries on Magnetic and Thermoelectric Properties of Cu-Added BiFeO.

In this study, bismuth ferrite (BFO) and copper-added BFO were synthesized using the coprecipitation method. The incorporation of copper into the BFO lattice led to a reduction in the phase percentage of BFO due to the early formation of CuBiO. X-ray diffraction analysis revealed a decrease in crystallite size up to 0.

The purest and unrestricted source of stem cells is the enamel of the teeth. Dental stem cells (DSCs), which are simple to get, quick to use, and reasonably priced, have the potential to be used in a variety of promising therapeutic applications. Due to their capacity for self-renewal, they are employed to treat significant flaws brought about by diseases, injuries, or surgical procedures.

TCAD simulation study of heavy ion radiation effects on hetero junctionless tunnel field effect transistor.

Semiconductor devices used in radiation environment are more prone to degradation in device performance. Junctionless Tunnel Field Effect Transistor (JLTFET) is one of the most potential candidates which overcomes the short channel effects and fabrication difficulties. In this work, 20 nm JLTFET is proposed with Silicon in the drain/channel region whereas source uses different materials, Silicon Germanium (SiGe), Gallium Nitride (GaN), Gallium Arsenide (GaAs), Indium Arsenide (InAs).

An Evaluation of the Efficacy and Acceptability of Basal Implants in Traumatically Deficient Ridges of the Maxilla and the Mandible.

Background and objective Rehabilitation of edentulous jaw areas is a complex procedure that has witnessed numerous advancements in technique and materials for better functional and aesthetic outcomes over the years. Dental implants have emerged as a cutting-edge, cost-effective, and non-invasive alternative to traditional removable partial dentures (RPDs), fixed partial dentures (FPDs), and full dentures. In this study, the basal implant was tested in traumatically deficient ridges on the mandible and the maxilla to determine its effectiveness and acceptability.

Rohitukine content across the geographical distribution of Hook F. and its natural derivatives as potential sources of CDK inhibitors.

is an important medicinal plant distributed in the Western Ghats of India. The species has gained international importance for its anticancer component, rohitukine, a chromone alkaloid. Flavopiridol, P-276-00 and IIIM-290 are the derivatives of rohitukine in clinical trials against a wide range of cancers.

Structural formation of multifunctional NiMoO nanorods for thermoelectric applications.

We report on the synthesis and characterization of NiMoO (NMO) nanorods the hydrothermal method. The High-Resolution Scanning Electron Microscopy (HRSEM) image reveals the nanorod morphology of NMO. The formation of mixed phase α,β-NMO is confirmed and the crystallite size of the nanorods is measured to be 40 nm from the XRD data.

Comparing a deep learning model's diagnostic performance to that of radiologists to detect Covid -19 features on chest radiographs.

Background: Whether the sensitivity of Deep Learning (DL) models to screen chest radiographs (CXR) for CoVID-19 can approximate that of radiologists, so that they can be adopted and used if real-time review of CXRs by radiologists is not possible, has not been explored before.

Objective: To evaluate the diagnostic performance of a doctor-trained DL model (Svita_DL8) to screen for COVID-19 on CXR, and to compare the performance of the DL model with that of expert radiologists.

Materials And Methods: We used a pre-trained convolutional neural network to develop a publicly available online DL model to evaluate CXR examinations saved in .

Fluoroquinolone Resistance in Clinical Isolates of e.

 Fluoroquinolones are widely used broad-spectrum antibiotics. Recently, increased rate of resistance to this antibiotic has been observed in Klebsiella pneumoniae. The aim of the present study was to determine the presence of quinolone resistance determining regions (QRDR) mutation genes and plasmid-mediated quinolone resistance (PMQR) determinants in clinical isolates of ciprofloxacin-resistant K.

Effect of Frequency and Duration of Tobacco Use on Oral Mucosal Lesions – A Cross-Sectional Study among Tobacco Users in Hyderabad, India.

Purpose: Tobacco use is one of the most important risk factors for the development of oral mucosal lesions including oral pre-cancer and cancer. The type and location of the lesion varies with the type of tobacco used, the way it is used, and the frequency and duration of use. Hence, the present study aimed to determine the effect of frequency and duration of tobacco use on oral mucosal lesions among tobacco users in Hyderabad city.

Peptide specific monoclonal antibodies of Leptospiral LigA for acute diagnosis of leptospirosis.

Leptospirosis is underdiagnosed due to low sensitivity, need of specialised equipment, and expensive reagents for serological and molecular diagnosis respectively. Considering the sensitivity, rapidity, inexpensive reagents and collection of clinical samples, the monoclonal antibody based antigen detection method from urine samples has been developed and evaluated. LigA (LK90) based B-cell specific epitopes were predicted and synthesised as peptides for the production of monoclonal antibody.

Congenital CSF Rhinorrhoea sans Encephalocoele, sans Trauma, sans Tumour.

The authors describe a case of cerebrospinal fluid rhinorrhea due to a congenital defect in cribriform plate, an anomaly that has not been described hitherto. It was successfully treated surgically.

Prospects for discriminating Zingiberaceae species in India using DNA barcodes.

We evaluated nine plastid (matK, rbcL, rpoC1, rpoB, rpl36-rps8, ndhJ, trnL-F, trnH-psbA, accD) and two nuclear (ITS and ITS2) barcode loci in family Zingiberaceae by analyzing 60 accessions of 20 species belonging to seven genera from India. Bidirectional sequences were recovered for every plastid locus by direct sequencing of polymerase chain reaction (PCR) amplicons in all the accessions tested. However, only 35 (58%) and 40 accessions (66%) yielded ITS and ITS2 sequences, respectively, by direct sequencing.

Drosophila protein interaction map (DPiM): a paradigm for metazoan protein complex interactions.

Proteins perform essential cellular functions as part of protein complexes, often in conjunction with RNA, DNA, metabolites and other small molecules. The genome encodes thousands of proteins but not all of them are expressed in every cell type; and expressed proteins are not active at all times. Such diversity of protein expression and function accounts for the level of biological intricacy seen in nature.

Water-mediated ionic interactions in protein structures.

It is well known that water molecules play an indispensable role in the structure and function of biological macromolecules. The water-mediated ionic interactions between the charged residues provide stability and plasticity and in turn address the function of the protein structures. Thus, this study specifically addresses the number of possible water-mediated ionic interactions, their occurrence, distribution and nature found in 90% non-redundant protein chains.
