The present work reports acid blue 80 (AB80) adsorption performances on the activated carbon prepared from Nerium oleander fruits (NAC). Langmuir isotherm model and pseudo second order were determined to be best fitting models for AB80 NAC, its maximum capacities calculated 88.03, 102.04, 113.96 mg g-1 at 25, 35, 45 °C, respectively. Also, efficiency of increased as pH decreased. While rate was...

In vitro studies with N-acetylcysteine (NAC) solutions used for inhalation treatment have demonstrated inactivation of some antibiotics by NAC. Oral NAC treatment is increasingly common for long-term prophylaxis in chronic bronchitis. During exacerbations, treatment with oral antibiotics will often be given simultaneously. We assessed the effect of simultaneous oral administration of NAC on the...

Abstract The Proterozoic assembly of Australia, the understanding which is critical for reconstructing supercontinents, involved amalgamation West Australian (WAC), North (NAC), and South cratons (SAC). However, basement between these Archean to early lithospheric blocks mostly buried beneath younger basins; hence, its composition age timing remain uncertain. In situ zircon U-Pb-O-Hf analyses i...

Abstract Background With the expansion of use neoadjuvant chemotherapy(NAC) in locally advanced breast cancer (LABC), both dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) and 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET CT) are promising methods for assessment tumor response during chemotherapy. We aimed to evaluate diagnostic accuracy DCE-MRI &18 F-FDG PE...

We evaluated the in vitro effect on clonogenic potential (CFU-GM) and apoptosis in myelodysplastic syndromes (MDS) progenitors of an anti-oxidant (N-acetylcysteine, NAC) and/or a differentiating (all-trans retinoic acid, ATRA) agent. NAC significantly reduced apoptosis, both NAC and ATRA induced an increase in CFU-GM, but NAC seemed to be particularly effective in the high risk (HR) MDS. NAC + ...

N-acetyl-L-cysteine (NAC) is an antioxidant molecule endowed with immunomodulatory properties. To investigate the effect of NAC on the induction phase of T cell responses, we analyzed its action on human dendritic cells (DC) derived from adherent PBMC cultured with IL-4 and granulocyte-macrophage CSF. We first found that NAC inhibited the constitutive as well as the LPS-induced activity of the ...

Reward-predictive cues exert powerful control over behavioral choice and may be a critical factor in drug addiction. Reward-seeking elicited by predictive cues is facilitated by the release of dopamine in the nucleus accumbens (NAc), yet the contribution of dopamine to the specific NAc firing patterns that underlie goal-directed behavior has remained elusive. We present evidence that subpopulat...

BACKGROUND AND OBJECTIVES ESRD is associated with systemic oxidative stress, an important nontraditional risk factor for the development of cardiovascular disease. Since interventions aimed at reducing oxidative stress may be beneficial, we examined the pharmacokinetics and pharmacodynamics of the widely used antioxidant N-acetylcysteine (NAC) after oral administration in patients with ESRD. ...

ied this possibility by performing the enzymatic assay on controls containing increasing concentrations of ACET in the presence of different therapeutic concentrations of NAC (Fig. 1A). Evidently, NAC concentrations $100 mg/L cause a marked negative bias, reaching total suppression of the reaction in the presence of 10 g/L NAC. In contrast, similar concentrations of NAC have no effect on the AC...

Notch3 receptor is expressed in a variety of cancers and the excised active intracellular domain (N3ICD) initiates its signaling cascade. N-acetylcysteine (NAC) as an antioxidant has been implicated in cancer prevention and therapy. In this study, we demonstrated a negative regulation of Notch3 by NAC in cancer cells. HeLa cells treated with NAC exhibited a time- and concentration-dependent dec...
