Essential protein (melanin) that is vital for the skin for defense from UV rays. In the present research, emerging drug ACE was examined for its melanin inhibition using three different (in vitro, in vivo and computational) methods. ACE showed remarkable potency (IC 50 = 0.353 ± 0.003 µM) against tyrosinase in the comparison of standard, kojic acid (IC 50 = 16.841 ± 1.161 µM) and ACE exhibited competitive inhibition. In the in vivo study zebrafish embryos were exposed with 5, 10, 15 and 20 µM of ACE and same doses for positive control (Kojic Acid). At 72 h treatment, ACE expressively (P<0.001) reduced the level of pigmentation (62.89%) at a concentration of 20 µM, relative to that of kojic acid (39.64%). The binding profile of ACE was confirmed by molecular docking and the stability of the docked complexes was justified by MD simulation. Based on our results, it was concluded that ACE possessed good therapeutic potential against melanogenesis by targeting the tyrosinase.","PeriodicalId":19846,"journal":{"name":"Pakistan Journal of Analytical & Environmental Chemistry","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2020-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41616175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Themal springs were characterized by flame photometery, graphite furnace atomic absorption spectroscopy, ion chromatography, inductively coupled plasma atomic emission spectroscopy, X-ray flourescent spectrometry, atomic absorption spectroscopy and titrations (argentometric, acidemetic & complexometric). They are classified on the basis of pH, temperature and mineral contents. The common mineral contents in these springs include 0.67-621.99 mg/L sodium, 0.67-189 mg/L potassium, 2.06-84 mg/L calcium, 0.00-56 mg/L magnesium, 0.12-12 mg/L fluorides, 0.00-982.62 mg/L chlorides, 0.15-442 mg/L sulphates and 4.3-494 mg/L bicarbonates. Their temperatures were found in the range of 26.0-90.50 °C with the pH 2.0-9.7 and TDS value of 104.74-2188 mg/L. The mineral concentration in most thermal springs is highly ideal for the treatment of numerous diseases including atopic dermatitis, psoriasis, rosacea, diabetes, rheumatoid arthritis, ankylosing spondylitis, osteoarthritis, chronic rhinosinusitis, chronic bronchitis/asthma, obesity, wounds healing and cardiovascular diseases. For curative purposes, the body is soaked in thermal waters or water may be used in the form of drinking/inhaling.","PeriodicalId":19846,"journal":{"name":"Pakistan Journal of Analytical & Environmental Chemistry","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2020-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49585034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maximum sorption capacities 2.82 mg/g and 4.93 mg/g were calculated for As(III) and As(V) at pH-6 and pH-4, respectively. The energy values of the sorption 3.31-5.89 (<8) kJ/mole indicated the physisorption. The applicability of Halsey isotherm supported the heteroporosity of the biomass. Mechanism of the reaction was best explained by pseudo first order rate, Morris-Weber and Richenberg equations. Intra-particle diffusion as well as surface sorption was noticed during the study. Equilibrium was achieved up to 120 minutes. Thermodynamically, sorption reaction was endothermic and spontaneous in nature.

Membranes of different compositions were synthesized and the best morphology was achieved with 0.5 g of PVC, 1.0 g of pAMPS and 0.015 g of filler. The synthesized membrane and inorganic filler were characterized using SEM, EDS, FTIR, Raman and XRD spectroscopy. Moreover, the gas permeation studies were performed to check the separation factor of synthesized membrane for O2/N2. The maximum permeability achieved for O2 and N2 was 4097 and 3373 barrers, respectively at 5 bar pressure. For the selectivity, a gradual increasing trend was observed with the increase in permeability. The maximum selectivity achieved was 1.215 at 5 bar pressure.

This method was based on the oxidation of paracetamol in presence of slightly acidic (0.05 – 0.15 M H2SO4) aqueous solution with a prompt oxidizing agent, cerium(IV) for the direct spectrofluorimetric determination of paracetamol and the fluorescent species is an oxidation product of parcetamol, has excitation and emission wavelength at λex = 255 nm and λem = 350 nm, respectively. The fluorescence intensity of oxidation product reaches a constant value (after heating for 5 min at 45 ± 5°C) within 15 min remains stable for over 24 h. Numerous variables influencing the reaction’s conditions e.g. the concentrations of cerium(IV), temperature, effect of acidity, time of the reaction and solvents were cautiously experimented and optimized. Linear calibration graphs were obtained for 10–700μgL-1 of paracetamol, having a detection limit of 2μgL-1; the quantification limit of the reaction system was found to be 10μgL-1; the RSD was 0 – 2 % and the correlation coefficient, R2 = 0.9999. A large excess of over 40 potentially interfering excipients, commonly present in dosage forms were tested in the determination of paracetamol at 100μgL-1 level, do not intervene in the determination process. The developed method was successfully applied to the determination of paracetamol in commercial pharmaceutical formulations and biological fluids. The results of the proposed method for pharmaceuticals and biological analyses were analogous with that of spectrophotometric method and the Official method stated in the British Pharmacopoeia, and was found to be in an excellent agreement.","PeriodicalId":19846,"journal":{"name":"Pakistan Journal of Analytical & Environmental Chemistry","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2019-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42739805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electrochemical arc discharge was performed between two graphite rods inserted in an aqueous solution of 1% acetonitrile. The prepared CMBs were characterized using X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Attenuated Total Reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and Energy Dispersive Xray (EDX) analysis for confirmation of their characteristic properties. The existence of spherical shape and smooth surface of the CMBs was confirmed by SEM with diameters in the range of 80μ-300 nm, and the EDX analysis exhibited the composition of CMBs with atomic mass percents of carbon (88.35%) and oxygen (11.65%). Similarly, the XRD analysis revealed the crystalline graphitic carbon nature of the CMBs with an average crystallite size calculated from the major diffraction peak using the Scherrer formula of about 40.59 nm.
