Pituitary neuroendocrine tumors (PitNET) are originating from adenohypophyseal cells. Although benign, PitNETs sometimes exhibit aggressive biological behavior that was the inspiration for change of old and traditional name "pituitary adenomas". Current standard in PitNET diagnostics, according to WHO criteria, is immunohistochemistry, with application antibodies adenohypophysis hormones transc...

metastasis from breast cancer to other parts of the body is very common, but the spread of the tumor to pituitary gland, especially to infandibulum, is a rare presentation. at the time of pituitary metastasis, a majority of the patients have clinical and radiological evidence of the disease. it seems that the posterior area of the gland is the most common site of metastasis, probably due to hig...

Pituitary stalk interruption syndrome (PSIS) is a rare congenital abnormality of the pituitary gland. It associated with either isolated growth hormone deficiency or combined (CPHD). Neonatal PSIS extremely and difficult to diagnose can be life threatening if diagnosed late. In this manuscript, we descripted case neonatal who treated at department ofPediatric Endocrinology atHassan II Universit...

Background: Cushing's disease is the most prevalent cause of endogenous adrenocorticotrophic hormone hypersecretion. The aim of this study was to document the current clinical practice pattern in the management of Cushing's disease by Iranian Endocrinologists to determine their opinions and compare them with the current clinical practice guidelines.    Methods: An eight-item questi...

this study explored the effects of gnrh agonist (gnrha) immunity on expression of fshr mrna in pituitary and fshr protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (eg) during anestrus season. animals in eg-i, eg-ii and eg-iii were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...

<p>One of the common causes death is a brain tumor. Because above mentioned, early detection tumor critical for faster treatment, and therefore there are many techniques used to visualize One these magnetic resonance imaging (MRI). On other hand, machine learning, deep convolutional neural network (CNN) state art technologies in recent years solving medical image-related problems such as ...

BACKGROUND The existence of pituitary stem cells in the adult pituitary gland is supported by such findings as postnatal proliferation, differentiation based on environmental alterations, and development of hormone-producing cells after specific lesions in the pituitary. OBJECTIVE We discuss which cells in the adult pituitary gland might play a role as pituitary stem cells, the potential for ...

the effectiveness of pituitary extract from crucian carp (carassius auratus linnaes 1758) in inducing ovulation in veil tail gold fish (carassius auratus gibelio bloch 1783), was examined and the effect of maternal hormone treatment on egg quality in two types of fertilization (fertilization in aquarium and artificial fertilization), were evaluated in 22·c temperature. fish were injected intrap...
