BACKGROUND: Hepatitis C virus (HCV) infection is the major cause of hepatocellular carcinoma (HCC), a common primary liver malignancy, and the third leading cause of cancer-related death. The HCC risk increases with the severity of liver inflammation, and the clinical course of HCV infection depends on a balance between pro- and anti-inflammatory cytokines. The former includes interleukin (IL)-6, while the latter includes IL-10. However, the exact pathogenic mechanisms underlying IL-6 and IL-10 effects remain unclear...

In the current study, the interfacial interactions between the high molecular weight (HMW) compounds of Skeletonema costatum (SKC) extracellular organic matter (EOM) and ZrO2 or Al2O3, were investigated by atomic force microscopy (AFM). HMW SKC-EOM was rigorously characterized and described as a hydrophilic organic compound mainly comprised of polysaccharide-like structures. Lipids and proteins were also observed, although in lower abundance. HMW SKC-EOM displayed attractive forces during approaching (i.e., leading to jump-to-contact events) and adhesion forces during retracting regime to both metal oxides at all solution conditions tested, where electrostatics and hydrogen bonding were suggested as dominant interacting mechanisms...

Tuning the emission energy of graphene quantum dots (GQDs) and understanding the reason of tunability is essential for the GOD function in optoelectronic devices. Besides material-based challenges, the way to realize chemical doping and band gap tuning also pose a serious challenge. In this study, we tuned the emission energy of GQDs by substitutional doping using chlorine, nitrogen, boron, sodium, and potassium dopants in solution form. Photoluminescence data obtained from (Cl- and N-doped) GQDs and (B-, Na-, and K-doped) GQDs, respectively exhibited red- and blue-shift with respect to the photoluminescence of the undoped GQDs...

The ATP - binding cassette (ABC) family G2 (ABCG2) transporters are known to produce multidrug resistance (MDR) in cancer, thereby limiting the clinical response to chemotherapy. Molecular modeling data indicated that certain dopamine (DA) D3 receptor antagonists had a significant binding affinity for ABCG2 transporter. Therefore, in this in vitro study, we determined the effect of the D3 receptor antagonists PG01037, NGB2904, SB277011A, and U99194 on MDR resulting from the overexpression of ABCG2 transporters...

BACKGROUND: Tuberculosis (TB) ranks as the second leading cause of deaths due to infectious diseases. Although global efforts have been made to control TB, still, this is a serious threat as Mycobacterium tuberculosis (MTB) produced resistance against both the first- and second-line drugs. The increasing incidence of multidrug-resistant, extremely drug resistant, and totally drug-resistant TB worldwide requires extra efforts to search for new anti-TB drugs. MATERIALS AND METHODS: The present study evaluated the antimycobacterial activities of Citrullus colocynthis, Calotropis procera, Ricinus communis, Capparis decidua, and Fagonia cretica plants' extracts against rifampicin-sensitive (H37Rv) and rifampicin-resistant (TMC331) strains of MTB...
