Pr（ Ⅲ ） and nd（ Ⅲ ） can be utilized as absorption spectroscopic probes to investigate the interaction of biomolecules like Lysozyme （HEW） with Ca（ Ⅱ ） in-vitro ; the most abundant metal ion in the human body system. The spectroscopic techniques involving comparative absorption, absorption difference, and quantitative intensity analysis using 4f-4f transitions are utilized for changes in the inner sphere coordination pattern of Pr（ Ⅲ ） and nd（Ⅲ ） in solution as well as in solid state. The present study deals with an important biomolecule in human metabolism, that is, Lysozyme （HEW）. The absorption er-Condon the probab spectral parameters such as the oscillator strength （P）, the Judd-Ofelt （Tλ） intensity parameters, and the Slatinter electronic parameters are calculated using chi square methods. The obtained results are used to determine le geometry of the complex in the solution, the nature of the bond between Pr（Ⅲ）/nd（Ⅲ） with lysozyme, and the inner sphere coordination environment of f-f transitions. The results obtained from various experimental conditions are utilized to investigate the coordination changes in the Pr（Ⅲ）/nd（Ⅲ） complexes caused by different coordinating sites of lysozyme, normalized bite, denticity, the solvent nature, the coordination number, the nature of bond and other parameters to mimic the interaction of the Ca（ Ⅱ ） ion with such biomolecule.

Eu（ Ⅲ ） can be utilized as an indirect electrochemical probe to investigate the interaction of bio-molecules such as DOPA and Dopamine with Ca（ Ⅱ ） in vitro. The interaction of DOPA and Dopamine with Eu（ Ⅲ ）-Eu（ Ⅱ ） redox pair was investigated by electrochemical techniques. Both the neurotransmitters are structurally related and undergo interaction with Eu （Ⅲ ）. Eu （ Ⅲ ） coordinates with DOPA and Dopamine through five-member chelate tings via carboxylic oxygen and amino nitrogen. The electrode kinetic parameters viz, transfer coefficient （αna）, diffusion coefficient （D）, forward heterogeneous rate constant （ k^0 fh） were evaluated for Eu（ Ⅲ ）-DOPA/Eu（ Ⅲ ）-Dopamine. The results obtained were used to investigate the nature of interaction of Eu （Ⅲ） with muhi-donor biomolecules. The possible mechanism was also proposed.

Introduction: nonalcoholic fatty liver disease (nAFLD) is a chronic liver disease ranging from liver steatosis to nonalcoholic steatohepatitis (nASH). Besides lifestyle modifications, Vitamin E (800 IU/day) is generally recommended for nASH. Vitamin E monotherapy is not sufficient for the multifaceted disease like nALFD. The combination of Vitamin E 400IU and Fraxinus excelsior 500 mg twice daily was found to be better than vitamin E 400 IU twice daily in improving the lipid profile and liver function parameters in patients with nAFLD. We conducted a study to assess safety and effectiveness of Vitamin E plus Fraxinus excelsior in Indian patients with nAFLD in real-world settings. Patients and Methods: This was a non-interventional study in nAFLD patients with varying grades of steatosis conducted by 234 physicians across India from January 2018 to August 2018. Patients received combination of Vitamin E (400 IU) and Fraxinus excelsior (500 mg) soft gelatin capsules twice daily after meals for 12 weeks. Effectiveness of the treatment was assessed at visit 2 (6 weeks) and visit 3 (12 weeks, end of study) from baseline. The parameters for assessment included severity of liver steatosis, liver function parameters and the global assessment of safety and effectiveness. Results: A total of 1114 patients were included in the study. At baseline, majority of the patients (71.18%) had Grade II liver steatosis followed by 21.01% and 7.81% patients who had Grade III and Grade I liver steatosis, respectively. After 12 weeks of treatment with vitamin E and Fraxinus excelsior combination, 21% patients had no steatosis, 58.79% patients were in Grade 1 steatosis, 19.57% in grade II steatosis and only 0.63% patients in Grade III steatosis. The mean percentage reduction in aspartate aminotransferase (AST) level at week 6 and week 12 from baseline was 24.92% and 43.79%, respectively. Similarly, the mean percentage reduction in alanine aminotransferase (ALT) level at week 6 and week 12 fr
