Background & Aims: Cancer is one of the most causes of mortality worldwide. Products derived from natural plants that induce apoptosis are used for cancer treatment. Therefore investigation of different herbal components for new anti-cancer drug is one of the main research activities throughout the world. This study is the first to investigate the cytotoxic and apoptotic effect of Anacyclu...
Incheh granitoid intrusion is located east of Herris, East-Azerbaijan Province. It intruded into the older rock units including Eocene volcanic – volcaniclastics. Compositionally, this intrusion ranges from diorite-quartz diorite to monzonite. Chemical composition of its major minerals such as feldspars, amphibole and clinopyroxene analyzed using electron probe micro-analyzer (EPMA) for thermob...
سامانه جمع‌آوری داده‌های آزمایشگاهی توکامک الوند یک سامانه بسیار قدیمی 32 کاناله است. ظرفیت دادهگیری هر کانال KB 2 و در مجموع KB 64 است و داده‌های تجربی به ترتیب در کانال‌های انتخاب شده با الگوی باینری ذخیره می‌شوند. یکی از مهم‌ترین کاستی‌های سامانه دادهگیری توکامک الوند جهت نمایش داده‌های تجربی استفاده از مبدل گرافیکی با قدرت تفکیک 240×320 پیکسل در عمق رنگ چهار بیت است که با توجه به ...
Paracetamol (known as acetaminophen, or APAP) poisoning causes acute liver damage that can lead to organ failure and death. We sought determine APAP overdose augment tumor necrosis factor-alpha (TNF-α)/ nuclear factor kappa B (NF-kB)/induced nitic oxide synthase (iNOS) axis-mediated hepatotoxicity in rats, the anti-inflammatory polyphenolic compounds, quercetin (QUR) plus resveratrol (RES) ame...
Bu çalışmada, tekstil fabrikalarından alınan pamuk çiğidi küspesi (PÇK) ile biber kırmızı işleme atıklarından (KB) enerji üretim amaçlı pelet elde edilmesi amaçlanmıştır. Elde edilen peletlerin fiziksel ve kimyasal özellikleri beraber mekanik özellikleri, ısıl yanma belirlenmiştir. Materyaller partikül boyutuna getirilip farklı oranlarda 5 karışım (%100 PÇK, %75 PÇK+%25 KB, %50 PÇK+%50 %25 PÇK+...
We have isolated two etoposide (VP16)-resistant cell lines, KB/VP-1 and KB/VP-2, from human cancer KB cells after stepwise exposure to increasing doses of VP16. KB/VP-1 and KB/VP-2 showed 30and 50fold higher resistance to VP16 and also 20and 30-fold higher resistance to teniposide than the parent cell line. Furthermore, both resistant cell lines showed more than 2-fold cross-resistance to Adria...

In order to investigate the involvement of cyclooxygenase (COX)-2 in cell growth and invasion of oral cancer, a human epidermoid carcinoma cell line KB minimally expressing COX-2 protein was transfected with COX-2 cDNA and these activities were compared with mock-transfected KB in vitro and in vivo. KB/COX-2 clones showed a similar growth rate in vitro compared to KB/neo clones, but demonstrate...
