Unravelling the evolutionary and developmental mechanisms that have impacted the mammalian dentition, since more than 200 Ma, is an intricate issue. Interestingly, a few mammal species, including the silvery mole-rat Heliophobius argenteocinereus, are able to replace their dentition by the addition of supernumerary molars at the back of jaw migrating then toward the front. The aim here was to d...
یادگیری فرآیندی است که در آن دانش و اطلاعاتی را درباره جهان به دست می آوریم. استفاده از آگونیست و آنتاگونیست های انتخابی سروتونین مشخص کرده است که این مونوآمین در یادگیری و حافظه دخیل است. ناحیه تگمنتوم شکمی از هسته رافه میانی و پشتی عصب های سروتونرژیک دریافت می کند. اندوکانابینوئیدها در فرآیندهای رفتاری مثل حرکت، اضطراب، یادگیری و حافظه - - نقش تنظیمی عصبی مهمی دارند. در این مطالعه از موش ...
Background: Species identification in commercially processed food and feed products is one of the important issues. This study was conducted to develop a genetic method for the detection of pig and cattle species in processed food and feed products using newly designed species-specific primers targeting mitochondrial 12S rRNA gene fragments. Methods: Two sets of specific primers were designed ...
In the present study, orexinergic cell bodies within the brains of rhythmic and arrhythmic circadian chronotypes from three species of African mole rat (Highveld mole rat-Cryptomys hottentotus pretoriae, Ansell's mole rat--Fukomys anselli and the Damaraland mole rat--Fukomys damarensis) were identified using immunohistochemistry for orexin-A. Immunopositive orexinergic (Orx+) cell bodies were s...
زمینه و اهداف: بیماری مالتیپل اسکلروزیس (ms) نوعی بیماری التهابی و دمیلینه کننده سیستم اعصاب مرکزی است، که معمولاً در دوران جوانی تشخیص داده می شود و در اکثر موارد منجر به ناتوانی مزمن می گردد. بیش از نیمی از بیماران ms نقایص شناختی شامل اختلالات یادگیری و حافظه را تجربه می کنند. به نظر می رسد واکنش های خودایمنی علیه میلین در ایمونوپاتوژنز بیماری ms نقش داشته باشد. استرس اکسیداتیو و به دنبال آن ...
Female genital mutilation in different parts of the African continent isconsidered as one of the vast territory’s social problems. This social problem whichis accounted as an old tradition in different countries of the African continent hashad so many unpleasant physical and mental effects on urban and rural Africanwomen during recent centuries. Throughout recent decades, considerable effortsha...
Avian chlamydiosis is caused by Chlamydiophila psittaci with the highest infection rate in parrots (Psittacidae) and pigeons (Columbiformes). A two-year-old Congo African grey parrot was examined since the bird had shown clinical signs of anorexia, depression, diarrhea, and mild dyspnea and based on biochemical and hemathological analysis the bird was diagnosed as having anemia, leukocytosis, h...
The African naked mole-rat's (Heterocephalus glaber) social and subterranean lifestyle generates a hypoxic niche. Under experimental conditions, naked mole-rats tolerate hours of extreme hypoxia and survive 18 minutes of total oxygen deprivation (anoxia) without apparent injury. During anoxia, the naked mole-rat switches to anaerobic metabolism fueled by fructose, which is actively accumulated ...
