The modulating effect of N-acetylcysteine (NAC) on the activity of different antibiotics has been studied in Pseudomonas aeruginosa. Our results demonstrate that, in contrast to previous reports, only the activity of imipenem is clearly affected by NAC. MIC and checkerboard determinations indicate that the NAC-based modulation of imipenem activity is dependent mainly on OprD. SDS-PAGE of outer ...

Low-density lipoprotein (LDL) is non-atherogenic, while oxidized LDL (ox-LDL) is critical to atherosclerosis. N-acetylcysteine (NAC) has anti-atherosclerotic effect with largely unknown mechanisms. The present study aimed to determine if NAC could attenuate in vivo LDL oxidation and inhibit atherosclerosis. A single dose of human native LDL was injected intravenously into male C57BL/6 mice with...

(1)H NMR spectroscopy was applied to investigate the changes of cerebral metabolites in brain hippocampus, nucleus accumbens (NAC) and prefrontal cortex (PFC) of the rats subjected to subcutaneous twice-daily injections of 2.5mg/kg methamphetamine (MAP) for 7 days. The results indicated that MAP exposure induced significant behavioral sensitization and altered cerebral metabolites in rats. The ...

OBJECTIVE To investigate the survival outcomes in patients with bulky stage IIIC and IV ovarian cancer, treated by primary debulking surgery (PDS) and selective use of neoadjuvant chemotherapy (NAC) according to institutional criteria. METHODS Medical records for advanced ovarian cancer patients who were treated at National Cancer Center (NCC) between December 2000 and March 2009 were retrosp...

The nucleus accumbens (NAc) core is critical in the control of motivated behaviors. The muscarinic acetylcholine receptors (mAChRs) modulating the excitatory inputs into the NAc core have been reported to impact such behaviors. Recent studies suggest that ventral and dorsal regions of the NAc core seem to be innervated by distinct populations of glutamatergic projection neurons. To further exam...

UNLABELLED BACKGROUND Liver cancer is one of the most common malignancies in the world and at the moment, there is no drug intervention effective for the treatment of liver tumours. Investigate the effect of N-acetylcysteine (NAC), which has been studied for its antitumoural properties, on the toxicity of hepatocarcinoma (HCC) cells in vitro when used with the drug interferon alpha-2A (IFN),...

Neoadjuvant chemotherapy (NAC) is widely used to treat locoregionally advanced nasopharyngeal carcinoma (NPC). To determine the optimal number of NAC cycles, we assessed the effect of NAC cycle on survival outcomes of locoregionally advanced NPC patients receiving NAC before concurrent chemotherapy and intensity-modulated radiotherapy. Clinical data from 1,188 non-metastatic NPC patients were r...

Transmembrane protein 168 (TMEM168) comprises 697 amino acid residues, including some putative transmembrane domains. It is reported that TMEM168 controls methamphetamine (METH) dependence in the nucleus accumbens (NAc) of mice. Moreover, a strong link between METH dependence-induced adaptive changes in the brain and mood disorders has been evaluated. In the present study, we investigated the e...

Dopaminergic neurotransmission in the nucleus accumbens (NAc) and neural processes in the basolateral (BLA) and central (CeN) amygdala nuclei are implicated in associative reward learning. Given their direct and indirect connections with the NAc and ventral tegmental area (VTA), both the BLA and CeN may regulate the mesoaccumbens dopamine (DA) system in rewarding situations. Electrical stimulat...

The cysteine prodrug N-acetylcysteine (NAC) has been shown to reduce reinstatement of cocaine seeking by normalization of glutamatergic tone. However, enduring inhibition of cocaine seeking produced by NAC has not been explored under different withdrawal conditions. Thus, the present study determined whether chronic NAC administered during daily extinction training or daily abstinence after wit...
