Essential oils from mint plants, including peppermint and pennyroyal oils, are used at low levels as flavoring agents in various foods and beverages. Pulegone is a component of these oils. In a 2-year bioassay, oral administration of pulegone slightly increased the urothelial tumor incidence in female rats. We hypothesized that its mode of action (MOA) involved urothelial cytotoxicity and incre...

background l-tryptophan is an important ingredient in medicines, especially in neuromedicines such as antidepressants. many commercial processes employ various microorganisms with high tryptophan synthase activity to produce l-tryptophan from indole and l-serine, but these processes are very costly due to the costs of precursors, especially l-serine. objectives for this reason, we studied the a...

endo-derived nitric oxide (no) is synthesized from l-arginine by endothelium nitric oxide synthase (enos). since reduced no synthesis has been implicated in the development of coronary atherosclerosis; we hypothesized that polymorphisms of nos gene might be associated with increased susceptibility to this disorder and coronary artery disease (cad). we studied the 27 base pair tandem repeat poly...

background: l-tryptophan is used widespread in the pharmaceutical industry. the majority of l-trp production depends on microbial processes that produce l-tryptophan from indole and l-serine. these processes are very costly due to the costs of precursors, especially l-serine. use of inexpensive substitutions as the l-serine source of l-tryptophan production enables us to reach a cost-effective ...

This research evaluated the effects of biosolid levels on yield and chemical composition of Mentha piperita L. essential oil. Mint plants were grown in a greenhouse in pots containing the equivalent to 0, 28, 56, and 112 t.ha-1 biosolid. Three evaluations were made at 90, 110, and 120 days after planting (DAP). The oil was extracted from the dry matter of shoots by hydrodistillation, and compos...

گونه Mentha aquatic  در شهریور ماه 75 از رویشگاه طبیعی آن واقع در جنگلهای تحقیقاتی واز ( ارتفاع 1500 متری) جمع آوری واز برگ خشک شده آن به روش تقطیر با بخار آب اسانس گیری بعمل آمد.محصول بدست آمده، روغن اسانسی با بازده یک درصد () بود که ترکیبهای شیمیایی آن به روش گاز کروماتوگرافی (GC) کوپل شده با طیف سنجی جرمی (GC/MS) تایید گردیدند. تعداد هفده ترکیب در این روغن اسانسی شناسایی شدند که مجموعا 85.2...

aflp یک ابزار قدرتمند برای تشخیص رونوشت هایی با فراوانی کم است و می تواند بعنوان یک روش کارآمد برای جداسازی ژنهایی که بطور متمایز بیان می شوند، بکار رود. بنابراین القا متمایز ژنها در گندم ( رقم چمران و مرودشت) در پاسخ به قارچ m.graminicola بوسیله آنالیز cdna-aflp مورد مطالعه قرار گرفت . در ابتدا گیاهان بوسیله بیمارگر مایه زنی شدند. نمونه برداری در 6 نقطه زمانی(0، 12، 24، 48، 72 و 96 ساعت) بعد ا...
