68 WOUNDS www.woundsresearch.com Abstract: Objective. The purpose of this study was to reveal the effect of N-acetylcysteine (NAC) on random-skin flaps in rats. Introduction. N-acetylcysteine is an agent among free radical scavengers which is used primarily as a mucolitic agent. Experimental studies have demonstrated protective effects of NAC on hepatic, renal, lung, and intestinal injuries. Me...

Central glucagon-like peptide 1 receptor (GLP-1R) stimulation suppresses food intake, and hindbrain GLP-1 neurons project to numerous feeding-relevant brain regions. One such region is the nucleus accumbens (NAc), which plays a role in reward and motivated behavior. Using immunohistochemical and retrograde tracing techniques in rats, we identified a robust projection from GLP-1 neurons in the n...

N-acetyl-l-cysteine (NAC) exhibits protective properties in brain injury models and has undergone a number of clinical trials. Most studies of NAC have focused on neurons. However, neuroprotection may be complemented by the protection of astrocytes because healthier astrocytes can better support the viability of neurons. Here, we show that NAC can protect astrocytes against protein misfolding s...

The binding properties of the disulfide covalent bond between N-acetyl-L-cysteine (NAC) and human serum albumin (HSA) were investigated. HSA, purified from either healthy subjects or renal failure patients, was incubated with NAC in buffer and analyzed by 4VP-EG-Me column chromatography, which can distinguish between the redox states of the only free thiol of HSA. Although intact HSA was found ...

OBJECTIVES We sought to evaluate the cardiac and renal effects of an N-acetylcysteine (NAC)-enhanced intracoronary radiographic contrast agent. BACKGROUND Recent studies suggest that high-dose NAC provides better protection from contrast-induced nephropathy, and the antioxidant properties of NAC may also provide cardiac protection. The use of angiographic contrast agents as a drug delivery ve...

چکیده: در این مقاله به معرفی یک روش جدید در سیستم­های کنترل از راه­دور[i] غیر­خطی با وجود نامعینی­های دینامیکی در هر دو طرف پایه[ii] و پیرو[iii] و همچنین نامعینی در شتاب گرانشی در طرف پیرو خواهیم پرداخت. چنین سیستمی می­تواند در سیستم­های فضایی که ربات پیرو در ارتفاع نامعینی در حال کار است و مقدار شتاب گرانشی در دسترس نیست یا به­علت تفاوت در عرض جغرافیایی ربات­های پایه و پیرو و به­تبع آن تفاوت د...

Abstract Aim Pathological response to neoadjuvant chemotherapy (NAC) seeks induce tumour regression pre-operatively. The present study aimed assess NAC and evaluate the appropriateness of subsequent breast-conserving surgery (BCS) avoid disfiguration healthy breast tissue. Method Analysis all patients undergoing wide local excision (WLE) for primary cancer between April 2012 December 2020 at a ...

Oxygen free radicals released during endotoxemia may contribute to the lung injury of the adult respiratory distress syndrome (ARDS). As this syndrome occurs frequently after gram-negative sepsis in humans, we studied the effect of intravenous N-acetylcysteine (NAC), a free radical scavenger, upon the endotoxin (E)-induced model of ARDS in awake sheep. In vivo studies demonstrated that NAC atte...
