    STRUCTURAL AND FUNCTIONAL APPROACHES TOWARD ACTIVITY RESTORATION OF NOVEL CYSTATHIONINE BETA-SYNTHASE MUTATIONS by AL-SADEQ, DUAA WALID

    Published 2024
    “…In contrast, all the other CBS mutation studies did not fully retain heme and, when compared to the wild-type enzyme, exhibited more significant impairments in both the canonical cystathionine synthesis and the alternative H2S-producing reactions. This reduced activity is consistent with both in vitro and in silico evidence, which indicates that the studied CBS mutations, except p.K72I, significantly decrease the overall protein's stability, which may represent the underlying cause of their pathogenicity. …”

    Development of value-added polyethylene grades with extended service lifetime: Weathering resistant flame retarded materials for outdoor applications by Porfyris, A. D.

    Published 2021
    “…The current article deals with the development of different novel, tailor-made polyolefin formulations exhibiting both low flammability and high weathering resistance, so as to provide value-added polyethylene grades with extended service lifetime. Two low-density (LDPE) and one linear low-density (LLDPE) polyethylene grades were modified via melt compounding with an additive system comprising: (a) a nitrogen-phosphorous intumescent system for flame retardance and (b) a hindered amine light stabilizer and a benzophenone-type UV absorber for UV/heat stabilization, at a total loading of 30-35 wt%. …”

    Optimizing cancer therapy: a review of the multifaceted effects of metronomic chemotherapy by Basar, Oyku Yagmur

    Published 2024
    “…Metronomic chemotherapy (MCT), characterized by the continuous administration of chemotherapeutics at a lower dose without prolonged drug-free periods, has garnered significant attention over the last 2 decades. Extensive evidence from both pre-clinical and clinical settings indicates that MCT induces distinct biological effects than the standard Maximum Tolerated Dose (MTD) chemotherapy. …”
