Article Synopsis
  • The study investigates the anticancer effects of iron oxide nanoparticles (FeO NPs) on liver cancer cells (HepG2) by examining their impact on specific genes and apoptotic pathways.
  • FeO NPs were created using plant extracts and characterized through various techniques, including UV-Vis spectroscopy and MTT assays to assess their toxicity to HepG2 cells.
  • The findings show that nanoparticles derived from the first plant were more effective against cancer cells, as indicated by lower IC values and changes in gene and protein expression levels compared to those derived from the second plant.

Artemisia carvifolia Buch silver nanoparticles downregulate the Rap2A gene in liver cancer.

Sci Rep

December 2023

Department of Bioinformatics and Biosciences, Faculty of Health and Life Sciences, Capital University of Science and Technology(CUST), Islamabad, 44000, Pakistan.

Liver cancer is the second main reason of death globally. In the current study, Rap2A protein a member of Ras Gtpase was selected as a drug target for liver cancer which has been identified as an oncogene in different types of tumors. The present study aimed to evaluate Artemisia carvifolia Buch extract and its silver nanoparticles against liver cancer targeting the Rap2A gene.

Background: Glioblastoma (GBM) harbors significant genetic heterogeneity, high infiltrative capacity, and patterns of relapse following many therapies. The expression of nuclear factor kappa-B (NF-κB p65 (RelA)) and signaling pathways is constitutively activated in GBM through inflammatory stimulation such as tumor necrosis factor-alpha (TNFα), cell invasion, motility, abnormal physiological stimuli, and inducible chemoresistance. However, the underlying anti-tumor and anti-proliferative mechanisms of NF-κB p65 (RelA) and TNFα are still poorly defined.

Article Synopsis
  • - Geraniol (GER) is a natural compound that shows promise as an anti-inflammatory treatment, specifically tested for its effects on inflammatory arthritis in rats induced by Complete Freund's Adjuvant (CFA).
  • - After treatment with various doses of GER, the results indicated significant reductions in paw swelling and inflammation, comparable to those achieved with methotrexate, along with improvements in blood parameters associated with inflammation.
  • - The study suggests that GER works by decreasing levels of key pro-inflammatory proteins and enzymes, indicating potential for further development as a therapeutic option for arthritis.

The goal of this research is to investigate the effects of Ohmic heating, heat generation, and viscous dissipative flow on magneto (MHD) boundary-layer heat transmission flowing of Jeffrey nanofluid across a stretchable surface using the Koo-Kleinstreuer-Li (KKL) model. Engine oil serves as the primary fluid and is suspended with copper oxide nanomolecules. The governing equations that regulate the flowing and heat transmission fields are partial-differential equations (PDEs) that are then converted to a model of non-linear ordinary differential equations (ODEs) via similarity transformation.

Vortices capture the attention of every scientist (as soon as they come into existence) while studying any flow problem because of their significance in comprehending fluid mixing and mass transport processes. A vortex is indeed a physical phenomenon that happens when a liquid or a gas flow in a circular motion. They are generated due to the velocity difference and may be seen in hurricanes, air moving across the plane wing, tornadoes, etc.

For heating, ventilation or air conditioning purposes in massive multistory building constructions, ducts are a common choice for air supply, return, or exhaust. Rapid population expansion, particularly in industrially concentrated areas, has given rise to a tradition of erecting high-rise buildings in which contaminated air is removed by making use of vertical ducts. For satisfying the enormous energy requirements of such structures, high voltage wires are used which are typically positioned near the ventilation ducts.
