زمینه و هدف: کم‌تحرکی در مقابل آن تمرین جزء عوامل مرتبط با شاخص‌های آسیب کبدی به‌شمار می‌روند. وجود این هنوز نقش بسیاری از تمرین‌های ورزشی به‌ویژه تمرینات تناوبی مقاومتی مصرف برخی مکمل‌های غذایی جمله اسپیرولینا بر ایمنی التهابی کاملاٌ شناخته نشده است؛ بنابراین هدف پژوهش تعیین اثر هشت هفته مکمل‌دهی هوازی فعالیت بافت کبد بیان ژن CXCL1 عضلة موش‌های صحرایی نر بود.مواد روش‌ها: نیمه‌تجربی، 60 سر موش ن...

Background: Long term regular practice of soybean-chickpea and soybean-wheat system in the growing region is posing severe problems before growers such as low productivity, profitability monetary net return use efficiency due to delayed sowing wheat market value produce well poor economic viability this cropping system. Methods: A field trial was laid out during monsoon (rainy), winter late sea...

Three different concentrations of four (ethanol, acetone, methanol, and diethyl ether) extracts licorice, doum, banana peel were evaluated for antifungal antimycotoxigenic efficiency against a maize aflatoxigenic fungus, Aspergillus flavus. Among them, the licorice ether 75% extract was intensely active, showing best wet dry weight inhibition exhibiting highest efficacy ratio (91%). Regarding a...

Background and Purpose: Mycotoxins are secondary fungal metabolites with a very high diversity that are produced by some species of Aspergillus which frequently leads to contaminate food and agricultural products. Recently, elimination of aflatoxin contamination in food and feed has been considered by scientists worldwide. Although, the antibacterial and antifungal effects of vitamins as natura...

Aflatoxins are a potent carcinogenic mycotoxin and has become a research model of fungal secondary metabolism (SM). Via systematically investigating the APSES transcription factors (TFs), two APSES proteins were identified: AfRafA and AfStuA. These play central roles in the synthesis of mycotoxins including aflatoxin and cyclopiazonic acid, and fungal development and are consequently central to...

Homeobox proteins, a class of well conserved transcription factors, regulate the expression of targeted genes, especially those involved in development. In filamentous fungi, homeobox genes are required for normal conidiogenesis and fruiting body formation. In the present study, we identified eight homeobox (hbx) genes in the aflatoxin-producing ascomycete, Aspergillus flavus, and determined th...

Caleosins are a small family of calcium-binding proteins endowed with peroxygenase activity in plants. Caleosin-like genes are present in fungi; however, their functions have not been reported yet. In this work, we identify a plant caleosin-like protein in Aspergillus flavus that is highly expressed during the early stages of spore germination. A recombinant purified 32-kDa caleosin-like protei...

Zinc concentrations strongly influence aflatoxin accumulation in laboratory media and in food and feed crops. The presence of zinc stimulates aflatoxin production, and the absence of zinc impedes toxin production. Initial studies that suggested a link between zinc and aflatoxin biosynthesis were presented in the 1970s. In the present study, we utilized two zinc chelators, N,N,N',N'-tetrakis (2-...

Of all the food-contaminating mycotoxins, aflatoxins, and most notably aflatoxin B₁ (AFB₁), are found to be the most toxic and economically costly. Green farming is striving to replace fungicides and develop natural preventive strategies to minimize crop contamination by these toxic fungal metabolites. In this study, we demonstrated that an aqueous extract of the medicinal plant Micromeria grae...
