Staphylococcus epidermidis is the most frequent cause of nosocomial sepsis and catheter-related infections, in which biofilm formation is considered to be the main virulence mechanism. In biofilm environment, microbes exhibit enhanced resistance to antimicrobial agents. This fact boosted the search of possible alternatives to antibiotics. Farnesol and N-acetylcysteine (NAC) are non-antibiotic d...

Cancer mortality and morbidity are primarily related to recurrent tumors, and characterization of recurrence-associated genes should illuminate fundamental properties of tumor progression and provide new therapeutic targets. We have previously identified NAC-1, a member of the BTB/POZ gene family and a transcription repressor, as a gene associated with recurrent ovarian carcinomas after chemoth...

UNLABELLED N-acetylcysteine (NAC) is a thiol donor with antioxidant properties that has potential use as an ergogenic aid. However, NAC is associated with adverse reactions that limit its use in humans. PURPOSE The authors evaluated NAC efficacy as a thiol donor before handgrip exercise, measuring changes in serum cysteine and glutathione status and recording adverse reactions in adult subjec...

Introduction: 3-4, methylenedioxymethamphetamine (MDMA) causes apoptosis in nervous system and several studies suggest that oxidative stress contributes to MDMA-induced neurotoxicity. The aim of this study is to examine the effects of N-acetyl-L-Cystein (NAC) as an antioxidant on MDMA-induced apoptosis. Methods: 21 Sprague dawley male rats (200-250mg) were treated with MDMA (2×0,5mg/kg) or MDMA...

The dopaminergic innervation of the nucleus accumbens (NAc) is implicated in the selection and integration of motivationally relevant corticolimbic information that governs behavioral output. However, it is unknown whether the dopaminergic innervations of two anatomically distinct subregions of the NAc, core and shell, have differential roles in this gating process, and whether dopaminergic mec...

Synaptic modifications in nucleus accumbens (NAc) medium spiny neurons (MSNs) play a key role in adaptive and pathological reward-dependent learning, including maladaptive responses involved in drug addiction. NAc MSNs participate in two parallel circuits, direct and indirect pathways that subserve distinct behavioral functions. Modification of NAc MSN synapses may occur in part via changes in ...

For breast cancer patients who have undergone neoadjuvant chemotherapy (NAC), a sentinel lymph node biopsy (SLNB) has not been recommended until recently. This is due to the possible lymph-flow interruption caused by fibrotic changes following chemotherapy and possible increases in false-negative cases. We investigated the changes in the lymph-flow and the detection of sentinel lymph nodes (SLN...

background: fatalities from acetaminophen poisoning are common, but they are preventable by timely treatment with n-acetyl cysteine (nac). in many medical centers, nac is prescribed in keeping with the ingested dose of the drug as revealed through medical history. it seems to significantly differ from the real indications of nac administration based on plasma level of acetaminophen. overtreatme...

BACKGROUND Obstructive nephropathy decreases renal blood flow (RBF) and glomerular filtration rate (GFR), causing tubular abnormalities, such as urinary concentrating defect, as well as increasing oxidative stress. This study aimed to evaluate the effects of N-acetylcysteine (NAC) on renal function, as well as on the protein expression of aquaporin 2 (AQP2) and endothelial nitric oxide synthase...
