A cost-effective, eco-friendly, and highly efficient one-pot electrochemical process has been described for the synthesis of 4-1,3-benzoxazine and 4,5-dihydro-1,3-benzoxazepine derivatives by employing 2-aminobenzyl alcohols, 2-(2-aminophenyl)ethan-1-ol, isothiocyanate derivatives, and TBAPF as an electrolyte. The developed method is accomplished at 25 °C with a constant current of 20 mA. Utilizing a graphite anode and a platinum cathode in a dimethyl sulfoxide solvent, the devised metal-free electrochemical approach minimizes the production of waste and eliminates the need for external oxidizing agents.

The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, the Λ_{b}^{0}→Λ_{c}^{+}h^{-} decay parameters are measured.

Methods: Random cluster sampling method was used to assess the prevalence of CKD and anemia. Hematological analysis was carried out using autoanalyzer.
Aim: The present study is aimed to compare the effectiveness of dentinal tubule occlusion of two natural-based desensitizing toothpaste (Bentodent Desensitizer and Fang Farm Mint) and Novamin-based toothpaste (Shy-NM) under scanning electron microscope (SEM).
Materials And Methods: A total of 60 root dentin discs (3 mm-thick) were obtained from recently extracted permanent premolar teeth and were randomly divided into four groups based on the desensitizing toothpaste used, each group with 15 samples: Group I: Control, group II: Shy-NM, group III: Bentodent desensitizer, group IV: Fang Farm Mint. Samples were brushed for 2 min twice daily with a soft toothbrush with respective pea size amount of toothpaste for 14 days manually.
