Advances in computational modeling approaches in pituitary gonadotropin signaling [PDF]
Pituitary gonadotropins play an essential and pivotal role in the control of human and animal reproduction within the hypothalamic-pituitary-gonadal (HPG) axis. The computational modeling of pituitary gonadotropin signaling encompasses phenomena of different natures such as the dynamic encoding of gonadotropin secretion, and the intracellular cascades ...

Laser Doppler holography of the anterior segment for blood flow imaging, eye tracking, and transparency assessment [PDF]
Laser Doppler holography (LDH) is a full-field blood flow imaging technique able to reveal human retinal and choroidal blood flow with high temporal resolution. We here report on using LDH in the anterior segment of the eye without making changes to the instrument.

Pituitary Adenoma Volumetry with 3D Slicer [PDF]
In this study, we present pituitary adenoma volumetry using the free and open source medical image computing platform for biomedical research: (3D) Slicer. Volumetric changes in cerebral pathologies like pituitary adenomas are a critical factor in treatment decisions by physicians and in general the volume is acquired manually.

Estrogens induce expression of membrane-associated estrogen receptor α isoforms in lactotropes. [PDF]
Estrogens are key to anterior pituitary function, stimulating hormone release and controlling cell fate to achieve pituitary dynamic adaptation to changing physiological conditions. In addition to their classical mechanism of action through intracellular

Pituitary hyposignal characteristic of hemochromatosis on MRI
Pituitary haemochromatosis is an endocrine disorder caused by the accumulation of iron due to a lack of absorption during haemochromatosis. The characteristic appearance on MRI is a T2 and T2* hyposignal of the anterior pituitary gland without ...

Mathematical Modelling of Hypothalamus-Pituitary-Adrenal Axis Dynamics: A Review, a Novel Approach, and Future [PDF]
A novel mathematical model for the hypothalamic pituitary adrenal (HPA) axis is proposed to comprehend the oscillations observed in hormone concentration and potential dysfunction within the HPA axis in stressful situation. This model integrates impact of hippocampal receptors on the secretion of corticotropin-releasing hormone (CRH), an additional ...
