The Antioxidant and Pro-apoptotic effects of Sternbergia clusiana Bulb Ethanolic Extract on Breast Cancer Cells in vitro
منشور في 2021"…Among the various Amaryllidaceae species, Sternbergia clusiana has been recently given a great amount of attention in the medicinal field due to its richness in small chemical molecules, namely Amaryllidaceae alkaloids; these have been reported to possess an antioxidant and anti-inflammatory role, in addition to a prominent anti-cancer effect on different types of cancer cell lines. The current study investigates the selective anti-proliferative effect of Sternbergia clusiana bulb ethanolic extract (SbBEE) on breast cancer cells cultured in vitro (MDA-MB-231 and MCF-7) and reveals the underlying mechanism responsible for the induction of cell death. …"

A Dynamic Rotor Vertical-Axis Wind Turbine with a Blade Transitioning Capability
منشور في 2019"…The DR VAWT is capable of mimicking a Savonius rotor during the start-up phase and transitioning into a Darrieus one with increasing rotor radius at higher TSRs. The design exploits the fact that with increasing rotor radius, the TSR value increases, where the peak power coefficient is attained. …"

Performance analysis of a small-scale Orthopter-type Vertical Axis Wind Turbine
منشور في 2018"…Wind tunnel experiments were carried out to measure the torque of two-, three, and four-bladed turbine, each at a set of different wind speeds and blade aspect ratios. Increasing solidity was achieved by either decreasing the blade aspect ratio or increasing the number of blades, both resulting in a higher peak power coefficient (Cp,max) of the VAWT. …"

Dispersion of Volatile Organic Compounds (VOCs) Emissions from a Biofilter at an Electronic Manufacturing Facility
منشور في 2017"…When the removal efficiency drops due to a design or operational deficiency, odorous VOCs are released from the biofilter and this becomes evident by the increased odor complaints. Poor biofilter performance, geographical location of the facility, and meteorological conditions contribute to increased dispersion of VOCs. …"

Investigating The Efficacy of Ruxolitinib and CHIR-99021 in Targeting Pediatric Neuroblastoma Stem Cells
منشور في 2021"…In this study, we investigate the efficacy of two small molecules Ruxolitinib, a JAK/STAT inhibitor, and CHIR-99021, a GSK-3 inhibitor, in targeting pediatric neuroblastoma stem cells by testing them on human MYC-N amplified, IMR-32, and non-MYC-N amplified, SK-N-SH, cell lines. Treating neuroblastoma cells with Ruxolitinib and CHIR-99021 resulted in significant reduction in cellular proliferation, viability, apoptosis and tumorsphere formation capacity in both IMR-32 and SK-N-SH cell lines. …"

In vitro ischemia suppresses hypoxic induction of hypoxia-inducible factor-1α by inhibition of synthesis and not enhanced degradation
منشور في 2013"…We validated the use of a reporter containing the oxygen-dependent degradation domain of HIF-1α fused to firefly luciferase (ODD-luc) to monitor quantitatively distinct biochemical events leading to hypoxic HIF-1α expression or stabilization in a human neuroblastoma cell line (SH-SY5Y). When OGD was imposed following a 2-hr hypoxic stabilization of ODD-luc, the levels of the reporter were reduced, consistent with prior models proposing that OGD enhances HIF prolylhydroxylase (PHD) activity. …"
