The NAC domain was originally characterized from consensus sequences from petunia NAM and from Arabidopsis ATAF1, ATAF2, and CUC2. Genes containing the NAC domain (NAC family genes) are plant-specific transcriptional regulators and are expressed in various developmental stages and tissues. We performed a comprehensive analysis of NAC family genes in Oryza sativa (a monocot) and Arabidopsis thal...
در این تحقیق به‌منظور برآورد شتاب طیفی به‌صورت مستقیم با استفاده از روابط تضعیف در منطقه اصفهان (E54-5/49 و N1/34-31)، ابتدا،پارامترهای لرزهخیزی در گستره مورد بررسی به تفکیک ایالتهای لرزهزمینساختی منطقه محاسبه، و سپس، با استفاده از نقشه گسل‌ها و اطلاعات زمینلرزههای گذشته، نقشه‌ای از چشمه‌های بالقوه زمینلرزه برای منطقه اصفهان تهیه شده است. با استفاده از روابط تضعیف طیفی کمبل و بزرگنیا (2...
Introduction It has long been known that ionizing radiation can lead to detrimental effects in normal cells. In this light, Radioprotective chemicals have been used to decrease morbidity or mortality caused by ionizing irradiation. This study aimed to evaluate the radio-protective effect of N-acetylcysteineagainst radiation-induced mortality in male mice. Materials and Methods 52 healthy mal...
A toxic organic substance CCl4 is a well known model compound for studying detoxification function of the liver and developing oxidative stress. The goal study was to estimate effect L-glutamic acid (L-Glu) N-acetylcysteine (NAC) administration on rat blood parameters upon effects CCl4. Experimental male Wistar rats were injected intraperitoneally with CCl4, CCl4/L‑Glu group additionally L-Glu ...
مقدمه: خردل گوگردی از عوامل آلکیله کننده است که تشکیل رادیکال های آزاد را افزایش می دهد. هدف از این مطالعه بررسی نقش حفاظتی و درمانی داروهای هگزامتیلن تترآمین (hmt) و n– استیل سیستئین (nac) در کاهش استرس اکسیداتیو ناشی از خردل گوگردی در سرم موش صحرایی است. روش بررسی: در مطالعه تجربی حاضر، موش های صحرایی نر نژاد ویستار به طور تصادفی به 8 گروه تقسیم شدند. گروه کنترل، گروه خردل گوگردی (mg/kg5/0% ب...
BACKGROUND The purpose of this study was to determine the adequate loading and maintenance doses of N-acetylcyseteine (NAC) for patients suffering from acute ROS-induced injury. METHODS Concentrations of extra cellular NAC, cysteine (Cys), cystine (Cyst2), and methionine (Met) were measured in vitro, at which more than 50% of the intracellular ROS raised by paraquat were suppressed using Swis...
Esophageal squamous cell carcinoma (ESCC) is a gastrointestinal carcinoma with a poor prognosis. To improve the survival of patients with this disease, neoadjuvant chemotherapy (NAC) has been introduced. However, the survival benefits of NAC or the correlation between NAC and postoperative complications have not been well considered. In the present study, we retrospectively investigated the cli...
Background: N-acetylcysteine (NAC) is a putative antioxidant and has gained attention as a promising agent for chelating heavy metals including lead. Considering the animal studies results, we hypothesized that adding NAC to the treatment regimen may improve the success of treatment with lead chelators. Methods: A total of 46 patients who were lead-poisoned opioid addicts were divided into two ...
Orexin, mainly produced by orexin-expressing neurons in the lateral hypothalamus (LH), plays an important role in pain modulation. Moreover, it is shown that the nucleus accumbens (NAc) is one of the important areas involved in this modulation. Orexin-1 (OX1) and orexin-2 (OX2) receptors are densely distributed in the NAc. The study investigated the involvement of OX1 receptors in the NAc on an...
