This study was aimed at the investigation of the antioxidant effect of pumpkin seed oil against the oxidative stress-inducing potential of aflatoxin. For this purpose, 48 male BALB/c mice were used. Four groups, each comprising 12 mice, were established. Group 1 was maintained as the control group. Group 2 was administered with pumpkin seed oil alone at a dose of 1.5 mL/kg.bw/day (∼1375mg/kg.bw...

This paper has two primary purposes. First, it provides an elementary description and tutorial overview of the refracted-ray method of measuring fiber index profiles. Second, it presents new results concerning the theoretical foundation, the linearity and precision, and other aspects of the method. In particular, we find that index differences may be measured to 5% or better and conclude by sho...

Recently the importance of measuring in vivo action spectra for photodynamic therapy (PDT) with various photosensitizers was pointed out in this journal [1]. It was shown that the effect of PDT with zinc phthalocyanine tetrasulphonic acid (ZnPcS4) increases considerably when the wavelength of the activating light is increased from 680 to 692 nm. In this regard a further comparison with haematop...

The direct laser deposition (DLD) process has seen rigorous research in the past two decades due to its ability directly manufacture products followed by minimal machining. input variables play a vital role determining properties achieved manufactured DLD method. Inconel 625, nickel-based superalloy with exceptional mechanical performance and corrosion resistance, been used critical application...
