Fenestranes are an intriguing class of highly strained molecules possessing a quaternary carbon with bonds that deviate from the canonical tetrahedral geometry. Herein we report the discovery that the natural product pleuromutilin can be used as a structurally complex starting material for the synthesis of a series of bridged cis,cis,cis,cis-[4.5.5.5]- and cis,cis,cis,cis-[4.5.7.5]oxafenestrane...

Tagetes is a genus of 56 species of annual and perennial mostly herbaceous plants in the sunflower family (Asteraceae or Compositae).In this research our goal was recognizing the main components of the plant to extract useful ones. Essential oils of the leaves, seeds and flowers of Tagets minuta L., growing wild in Iran, were extracted by hydrodistillation an...
In this study the cis and trans regulatory effect of long non-coding genes (lncRNA) on the expression of genes in fish infected by Viral hemorrhagic septicemia virus (VHS) was investigated using RNA-seq technology. At the end of experimental period (the thirty fifth day), total RNA was extracted from spleen tissue (group treated with virus) and physiological serum (control group) was used to pr...
Assessing Virtual Water Trade Balance of Agricultural Products (A Case Study of Mazandaran province)
According to World Bank Report (2021), the agricultural sector consumes 70 percent of global freshwater. Therefore, managing and exploiting water resources optimally as well as future planning in this sector is necessary. Limited access to water endowments, unequal distribution of water resources, climate changes and increasing global water demand have increased the importance of the issue. Awa...
فساد مواد غذایی، تشکیل بیوفیلم به وسیله ی باکتری های مرتبط با غذا و باکتری های بیماری زای مرتبط با غذا، مشکل های اساسی در صنایع غذایی به وجود آورده است. اگرچه تمیز کردن زیاد و روش های ضدعفونی به طور کلی شرایط بهداشتی را در صنایع غذایی فراهم می کنند و سلول های آزاد و بیوفیلم هایی که در مراحل اولیه تشکیل خود قرار دارند را از بین می برند. cis-2- decenoic acid ، یک مولکول سیگنال از خانواده ی فاکتور...
به منظور بررسی اثر محلول پاشی عناصر کم مصرف آهن و روی بر عملکرد، اسانس و مواد موثر گیاه دارویی بابونه دو آزمایش در سال های 1387 و 1388 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه تبریز اجرا گردید. آزمایش ها به صورت طرح بلوک های کامل تصادفی با چهار تکرار پیاده گردید. تیمارها شامل محلول پاشی آهن، روی و آهن و روی (با غلظت 5/3 درهزار سولفات آهن و سولفات روی) در زمان های متفاوت (مرحله ساقه روی، مرحله ...
Background and Aim: Hemodynamic stability during anesthesia and operation is the most important aim of anesthesiologists. Every anesthetic drug has its own hemodynamic effects. The interaction of these drugs with each other and with preoperative drugs of the patients, may cause critical changes in patient's hemodynamic status. For a perfect anesthesia induction, while using high doses of op...
