The aim of the study was to examine the curative effects and proper radiotherapy plan of head γ-stereotactic radiotherapy (γ-SRT) for the treatment of functional pituitary macroadenoma. Clinical samples of 30 patients that underwent γ-SRT (radiotherapy group) and 26 patients that underwent pituitary adenoma resection via single nasal-sphenoidal approach (surgery group) were analyzed retrospecti...

Introduction Petrous apex cholesterol granulomas (PACGs) are uncommon lesions. Recurrence following transcranial or endonasal approaches to aerate the cyst occurs in up to 60% of cases. We describe the technical nuances pertinent to the endonasal endoscopic management of a recurrent symptomatic PACG and review the literature. Results A 19-year-old woman presented with a recurrent abducens nerve...

A 40-year-old male presented with headache, complete loss of vision in the right eye and decreased vision of the left eye. On examination, fundoscopy revealed secondary optic atrophy in the right eye and pale temporal disc in the left eye. MRI brain revealed a soft tissue mass arising from sphenoid sinus, eroding the overlying bone and extending into the sellar and parasellar regions up to the ...

The Pea enation mosaic virus (PEMV) 3' translational enhancer, known as the kissing-loop T-shaped structure (kl-TSS), binds to 40S subunits, 60S subunits, and 80S ribosomes, whereas the Turnip crinkle virus (TCV) TSS binds only to 60S subunits and 80S ribosomes. Using electrophoretic mobility gel shift assay (EMSA)-based competition assays, the kl-TSS was found to occupy a different site in the...

PURPOSE To investigate the prevalence and physical basis of a specific form of MR susceptibility artifact that may be seen in the pituitary gland near the junction of sellar floor and sphenoidal septum. MATERIALS AND METHODS Coronal, T1-weighted MR images of the pituitary glands in 50 subjects without clinical evidence of pituitary or sphenoidal sinus disease were reviewed to determine the pr...

The ITAM-bearing transmembrane signaling subunits (TSS) are indispensable components of activating leukocyte receptor complexes. The TSS-encoding genes map to paralogous chromosomal regions, which are thought to arise from ancient genome tetraploidization(s). To assess a possible role of tetraploidization in the TSS evolution, we studied TSS and other functionally linked genes in the amphibian ...

The best treatment for clival chordoma is obtained with total surgical excision, sometimes combined with adjuvant radiotherapy. A cerebrospinal fluid (CSF) fistula is a fatal complication that may occur following extended transsphenoidal surgery (TSS) and adjuvant radiotherapy. We report a case of fulminant meningitis without a CSF fistula in a 57-year-old woman who underwent TSS and multiple r...

Elevated suspended solids are a widespread stressor of aquatic ecosystems, but their effects on growth and reproduction in freshwater mussels are largely unknown. We fertilized experimental ponds to create a gradient in total suspended solids (TSS) and examined the effects of TSS on growth, nutritional status, reproduction, and clearance rate in Ligumia subrostrata. The number of females that b...

Cushing's disease (CD) in a stricter sense derives from pathologic adrenocorticotropic hormone (ACTH) secretion usually triggered by micro- or macroadenoma of the pituitary gland. It is, thus, a form of secondary hypercortisolism. In contrast, Cushing's syndrome (CS) describes the complexity of clinical consequences triggered by excessive cortisol blood levels over extended periods of time irre...
