background: acetaminophen (n-acetyl-p aminophenol; apap) is one of the most common types of analgesics. it is also the most common xneobitic reported to poison centers. this study investigates if therapeutic doses of nac can falsely increase coagulation tests, prothrombin time (pt) and bleeding time (bt). ​​ methods: thirty-six apap poisoned patients whose acetaminophen serum concentration were...

The production of reactive oxygen species in skeletal muscle is linked with muscle fatigue. This study investigated the effects of the antioxidant compound N-acetylcysteine (NAC) on muscle cysteine, cystine, and glutathione and on time to fatigue during prolonged, submaximal exercise in endurance athletes. Eight men completed a double-blind, crossover study, receiving NAC or placebo before and ...

INTRODUCTION Nipple-areola sparing mastectomy (NSM) is increasingly used in patients with non-locally advanced breast carcinoma. Literature data on the preoperative assessment of the nipple-areola complex (NAC) are inconsistent. PATIENTS AND METHODS Out of 1359 patients submitted to total mastectomy between 2001 and 2010, we selected 61 patients whose pre-operative mammogram (MX) was availabl...

Objectives. Level 1 evidence supports the use of neoadjuvant chemotherapy (NAC) to improve overall survival in muscle invasive bladder cancer; however utilization rates remain low. The aims of our study were to determine factors associated with NAC use, to more clearly define reasons for low utilization, and to determine the current rate of NAC use among urologic oncologists. Materials and Meth...

Polycystic ovary syndrome (PCOS) is associated with low-quality oocytes. The aim of the present study was to investigate the effects of metformin (MET), N-acetylcysteine (NAC) and their combination on follicular fluid parameters, oocytes and embryo quality in PCOS patients. A prospective randomised placebo-controlled pilot study on 60 Iranian women with PCOS (aged 25-35 years) undergoing intrac...

The dopamine D1 receptor (D1R) facilitates reward acquisition and its alteration leads to profound learning deficits. However, its minimal functional circuit requirement is unknown. Using conditional reconstruction of functional D1R signaling in D1R knock-out mice, we define distinct requirements of D1R in subregions of the nucleus accumbens (NAc) for specific dimensions of reward. We demonstra...

Neoadjuvant chemotherapy (NAC) is a widely‑used treatment for breast cancer, as it may render unresecta-ble breast tumors to become resectable. In addition, NAC provides the unique opportunity to assess response to treatments within months rather than years of follow‑up. However, predictive markers of tumor response to NAC are lacking. Therefore, the present study aimed to investigate the expre...

Asymmetric dimethylarginine (ADMA) reduces nitric oxide (NO), thus causing hypertension. ADMA is metabolized by dimethylarginine dimethylaminohydrolase (DDAH), which can be inhibited by oxidative stress. N-Acetylcysteine (NAC), an antioxidant, can facilitate glutathione (GSH) synthesis. We aimed to determine whether NAC can prevent hypertension by regulating the ADMA-DDAH pathway in spontaneous...

Abstract: Seeds of the genus Eugenia L. (Myrtaceae) have interesting propagation strategies, and reactive oxygen species (ROS) seem to be related their germination seedling production. In this study, effects ROS on E. involucrata seeds were analyzed indirectly, with application N-acetyl-L-cysteine (NAC), an antioxidant. The results demonstrated that incubation in NAC suppressed and/or delayed s...
