    Evaluating the Potential of Ozone Microbubbles for Inactivation of Tulane Virus, a Human Norovirus Surrogate حسب Bozhong Guan (18598178)

    منشور في 2024
    "…After 2, 10, and 20 min postgeneration, the ozone concentration of microbubbles naturally decreased from 4 ppm to 3.2 ± 0.2, 2.26 ± 0.19, and 1.49 ± 0.23 ppm and resulted in 1.43 ± 0.44, 0.88 ± 0.5, and 0.68 ± 0.53 log<sub>10</sub> viral reductions, respectively, while the ozone concentration of aqueous ozone decreased from 4 ppm to 2.52 ± 0.07, 0.43 ± 0.05, and 0.09 ± 0.01 ppm and produced 0.8 ± 0.28, 0.29 ± 0.41, and 0.16 ± 0.21 log<sub>10</sub> reductions against Tulane virus, respectively (<i>p</i> = 0.0526), suggesting that structuring of ozone in the bubbles over the applied treatment conditions did not have a significant effect, though future study with continuous generation of ozone microbubbles is needed.…"

    Dynamic of prolactin in pregnant women during pregnancy. حسب Francois Kiemde (5369657)

    منشور في 2024
    "…Code: *: <0.05; **: <0.01; ***: <0.001; ****: <0.0001. 30μl of plasma was used to determine the concentration of prolactin in blood (ng/ml). Prolactin levels were compared between multigravidae and primigravidae at each scheduled visits as described in “Method” section and presented as box and whisker plots illustration: top, bottom and middle of box, representing 25<sup>th</sup>, 75<sup>th</sup> and 50<sup>th</sup> percentiles, respectively. …"

    منشور في 2024
    "…In each case, 30μl of plasma was used to determine for cortisol level in blood (ng/ml). Cortisol levels were compared between multigravidae and primigravidae at each scheduled visits and presented as box and whisker plots illustration: top, bottom and middle of box, representing 25<sup>th</sup>, 75<sup>th</sup> and 50<sup>th</sup> percentiles, respectively. …"
