in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
Background and objective: Recent studies suggest that intermittent and prolonged normobaric hyperoxia (HO) results in ischemic tolerance to reduce brain injury. In this research attempts were made to see the changes in TNF-a converting enzyme (TACE) and NF-kB activity following intermittent HO and ischemia preconditioning. Materials and Methods: The rats were divided into two experimenta...

Purpose: Breast Cancer (BC) is considered as one of the most dangerous diseases, especially in women. The survivability patient a challenging task if breast cancer severe stage. It very much essential for early classification ultrasound images (BUIs) into several categories such benign (BN), malignant (MG) and normal (NL), etc. so that preventive measures can be taken accordingly at earliest. A...
background :adenosine is an endogenous purine nucleoside that has a neuromodulatory role in the central nervous system. the amphetamine derivative (±)-3,4-methylenedioxymethamphetamine (mdma or ecstasy) is a synthetic amphetamine analogue used recreationally to obtain an enhanced affiliated emotional response. mdma is a potent monoaminergic neurotoxin with the potential of damage to brain neuro...
مقایسه مولکولی جمعیت‌هایی از Meloidogyne javanica و Meloidogyne incognita در ایران با روش PCR – RFLP
To carry out this study, total DNA was extracted from eggs and from second stage juveniles of several populations of Meloidogyne javanica and Meloidogyne incognita, using phenol / chloroform method. Following extraction, DNA was electrophoresed on 1% agarose gel to determine its quality and quantity. A specific primer pair (C2F3 / 1108 23 and 20 nucleotides, respectively) was used to discrimina...
Introduction: Limiting cancer-induced cardiac atrophy is a highly important for improving the survival rates and quality of life in cancer patients. The purpose of this study was to evaluate the effect of 10 weeks of high-intensity interval training (HIIT) on cardiac muscle weight, NF-kB protein expression, and expression of Atrogin-1 and MuRF-1 genes in the heart muscle of breast cancer–bearin...
پیش زمینه و هدف: سرطان یک بیماری مهلک با آمار مرگ ومیر بالاست که درگیری های روانی و اقتصادی زیادی به دنبال دارد. استفاده از ترکیبات گیاهان دارویی القاکننده آپوپتوز از روش های درمان سرطان محسوب می گردند، لذا مطالعه بر روی گیاهان، جهت تولید داروهای ضد سرطانی جدید از فعالیت های تحقیقاتی مهم در دنیا می باشد. در مطالعه ی حاضر برای اولین بار اثرات سایتوتوکسیک و آپوپتوتیک عصاره گیاه عاقرقرحا در سلول ه...
مقدمه: می دانیم که میکروارگانیسم های دریایی یکی از منابع بسیار مهم ترکیبات جدید محسوب می شوند. اکتینومیست ها از باکتری های گرم مثبت رشته ای هستند که در همه جا گسترده می باشند و نقش بسیار مهمی را در توسعه داروها به ویژه داروهای ضدسرطانی ایفا می نمایند. روش بررسی: سویه دریایی باکتری استرپتومیسس گریزکولوآلبوس griscoloalbus streptomyces از مرجان نرم erecta sinularia واقع در خلیج فارس جداسازی شد. شر...
