Diencephalic origin of the pineal gland of the chicken embryo.

کلسیفیکاسیون فیزیولوژیک داخل جمجمه‌ای در غده پینه‌آل و شبکه کوروئید در مراجعه‌کنندگان به بخش سی‌تی اسکن بیمارستان امام رضا (ع) بیرجند در سال‌های 1376 لغایت 1385

Background and Aim: Intracranial physiologic calcification is not accompanied by any evidence of disease and has no demonstrable pathological cause. It is often due to calcium deposition in the blood vessels of different structures of the brain. Computed tomography (CT) is the most sensitive means of detection of for this calcification. The aim of this study was the assessment of the intracrani...

The development of the thalamic motor learning area is regulated by Fgf8 expression.

Habenular nuclei play a key role in the control of motor and cognitive behavior, processing emotion, motivation, and reward values in the brain. Thus, analysis of the molecular and cellular mechanisms underlying the development and evolution of this region will contribute to a better understanding of brain function. The Fgf8 gene is expressed in the dorsal midline of the diencephalon, close to ...

بررسی ریتم شبانه آنزیم ان - استیل ترانسفراز در غده پینه آل موش صحرائی

Living organisms have multiple biological rhythms. Some of these rhythms are endogenous and some are under the influence of light and dati cydes during 24-hours. Nowadays periodic changes in melatonin secretion from pineal gland and changes in N-acetyl transferase (NAT) activity which influence the melatonin secretion rate has been acknowledged as a basic rhythm. In this study NAT activity in p...

Development and photosensitivity of the rhythmic melatonin secretion of the chicken pineal gland

A Survey on Electrocardiographic Parameters in Broiler Chickens Following the Intracerebroventricular Injection of Melatonin

Objective- The pineal gland and its principal hormone melatonin play an important role in the circadian organization in birds. However, little is known about the role of melatonin in cardiac activity of broiler chicken. The aim of this study was to assess the impact of intracerebroventricular injection of melatonin in electrocardiographic parameters, heart rate and mean electri...
