UNLABELLED INTRODUCTION Langerhans cell histiocytosis is a rare disease within the adult population, with very few cases reported as solitary hypophyseal lesions in adults. Of the reported cases, most have been treated successfully with surgery, radiotherapy, and/or chemotherapy. Radiotherapy has been thought to be curative at the relatively low dose of 20Gy. Here we report a case of recurre...
SUMMARY Hypophyseal triplication is malformation that has not been described previously. We present a child with midline abnormalities who underwent epignathus excision at birth. Brain MR imaging revealed 2 paired lateral pituitary glands and an oval midline gland, each with an independent stalk, connected to a thickened third ventricle floor. Because malformations represent a failure in embryo...
Immunoperoxidase histochemical investigations on pig hypophysis show that CRF immunoreactive nerve terminals are distributed around the blood vessels in the posterior lobe, particularly in its proximal part adjacent to the intermediate lobe. CRF immunoreactive nerve fibers are also seen in the intermediate lobe. The distribution of the CRF-containing nerve in the posterior lobe was found to be ...
In Arabidopsis, the root meristem originates from the hypophyseal cell and from an adjoining cell tier that is distinct at the heart stage of embryogenesis. We have analysed mutations in the HOBBIT (HBT) gene that is essential for root meristem formation. hbt embryos display incorrect hypophyseal cell development from the quadrant stage onward. At the heart stage, the adjoining cell tier of hbt...
A 68-year-old female patient with previous history of transsphenoidal hypophysectomy operation underwent three-vessel coronary artery bypass graft (CABG) surgery for extensive coronary artery disease. Preoperative neurological examination revealed sequelae visual loss at right temporal visual field. Follow-up Magnetic Resonance Imaging studies showed a residual hypophyseal tumor tissue extendin...
In a previous publication, it was reported that solution of the hypophyseal growth hormone in acetate buffers results in an increment of its intrinsic viscosity with an accompanying increase of molecular weight (1). Later, Smith et al. (2) confirmed these observations in ultracentrifugal studies. The purpose of this present investigation has been to study the sedimentation behavior of the hormo...
The neurohypophysis is a crucial component of the hypothalamo-pituitary axis, serving as the site of release of hypothalamic neurohormones into a plexus of hypophyseal capillaries. The growth of hypothalamic axons and capillaries to the forming neurohypophysis in embryogenesis is therefore crucial to future adult homeostasis. Using ex vivo analyses in chick and in vivo analyses in mutant and tr...
