The formation of hemozoin (malaria pigment) has been proposed as an ideal drug target for antimalarial screening programs. In this study, we used an improved, cost-effective and high-throughput spectrophotometric assay to screen plant extracts for finding novel antimalarial plant sources. Fifteen extracts with different polarity from three Iranian Artemisia species, A. ciniformis, A. biennis an...

Background: Extremely low-frequency electromagnetic fields (ELF-EMFs) have gathered significant consideration for their possible pathogenicity. However, their effects on nervous system functions were not fully clarified. In this study, our aim was to assay the effect of ELF-EMFs with different intensity on memory, anxiety, antioxidant activity, beta amyloid (Aβ) deposition and microglia populat...

Objective Human Pygopus 2 (Pygo2) was recently discovered to be a component of the Wnt signaling pathway required for β-catenin/Tcf-mediated transcription. But the role of Pygo2 in malignant cell proliferation and invasion has not yet been determined. Methods Lentivirus-mediated small interfering RNA (siRNA) and vector-based overexpression were used to study the function of Pygo2 in OS-RC-2 c...

objective(s): in the current study antioxidant capacities of five different extracts of artemisia ciniformis aerial parts were evaluated by cell-free methods. then seven fractions of the potent extract were selected and their antioxidant capacity was assayed by cell free and cell based methods. materials andmethods: antioxidant ability was measured using the: 2, 2-diphenyl-1-picrylhydrazyl (dpp...

The antifungal effect and mucolytic activity of a newly screened biocontrol strain Chaetomium subaffine LB-1 were researched in this study. results found that has good effects on the test plant pathogenic fungi Botrytis cinerea Pers. ex Fr., Fusarium oxysporum f. sp. cucumerinum Owen Alternaria solani (Ellis & Martin) Sorauer dual culture assay, with inhibition rates 61.39, 50.34 51.22%, respec...

BACKGROUND Pseudomonas aeruginosa is an important nosocomial pathogen characterized by its innate resistance to multiple antimicrobial agents. Plasmid-mediated drug resistance also occurs by the production of extended-spectrum β-lactamases (ESBL), metallo β-lactamases (MBL), and AmpC β-lactamases. Another important factor for establishment of chronic infections by P. aeruginosa is biofilm forma...

PURPOSE To investigate the effects of anthelminthic drug niclosamide in renal cell carcinoma (RCC) and the underlying mechanisms of its action. METHODS The effects of niclosamide on the proliferation and apoptosis of RCC cells were examined in vitro and in vivo by using MTS, colony formation assay, flow cytometry and xenograft cancer mouse model. Mechanism studies were performed by analyzing ...

The glucotoxicity caused by long-term exposure of β-cells to high glucose (HG) conditions may lead the generation more reactive oxygen species (ROS), reduce activity antioxidant enzymes, cause cell damage and apoptosis, induce insulin secretion dysfunction. Siegesbeckia orientalis linne is a traditional folk herbal medicine used treat snake bites, rheumatoid arthritis, allergies, immune deficie...

Colorectal cancer (CRC) is the third most frequent and second leading cause of cancer-related deaths globally. Evidence shows that over 90% CRC cases are initiated by a deregulated Wingless Integrated Type-1 (WNT)/β-catenin signaling pathway. The WNT/β-catenin pathway also promotes cell proliferation, stemness, metastasis. Therefore, modulators may serve as promising regimens for CRC. This stud...
