150 Maxillary sinus hypoplasia (MSH) is the underdevelopment of maxillary sinus antrum and it is usually associated with other anomalies, such as uncinate process and infundibular passage. Hypoplasia is classified into three: Type I is mild hypoplasia, normal uncinate and infundibulum; Type II is significant hypoplasia with hypoplastic or absent uncinate and pathological infundibular passage; T...

The present study aimed to investigate the expression of aldosterone synthase (CYP11B2), adrenocorticotropic hormone receptor (ACTH-R) and their regulating transcription factors in adrenal incidentalomas (AIs) from normotensive and hypertensive patients to distinguish subclinical or atypical primary aldosteronism (PA) from AIs. Total RNA was extracted from 8 normal adrenal cortices (NAs), 46 AI...

AIMS Levels of enamel hypoplasia in past populations are frequently used to study health. However, few studies have looked at patterning in the occurrence of different types of hypoplasia. In this pilot study, skeletal remains from an Iron Age tomb at Pella in Jordan were analysed for the presence of linear and pit enamel hypoplasia, to investigate enamel hypoplasia aetiology by comparison of t...

adrenal insufficiency is a life-threatening disorder which must be treated with glucocorticoid replacement and needs permanent dose adjustment during patient's different somatic situations. insufficient glucocorticoid doses result in adrenal crisis and must be treated with intravenous hydrocortisone. the patient was known with adrenal insufficiency and was treated optimally with fludrocortisone...

The Dax-1 gene encodes a protein that is structurally related to members of the orphan nuclear receptor superfamily. Dax-1 is coexpressed with another orphan nuclear receptor, steroidogenic factor-1 (SF-1), in the adrenal, gonads, hypothalamus, and pituitary gland. Mutations in Dax-1 cause adrenal hypoplasia congenita, a disorder that is characterized by adrenal insufficiency and hypogonadotrop...

Basal plasma ACTH(1-39) concentrations are elevated in long-term hypoxic (LTH) fetal sheep. This study was designed to determine whether the expression of genes regulating cortisol biosynthesis was altered after LTH. Pregnant ewes were maintained at high altitude (3,820 m) from day 30 of gestation to near term, when the animals were transported to the laboratory. Reduced PO2 was maintained by n...

CONTEXT Excess production of aldosterone or cortisol has profound effects on cardiovascular function and impacts other major organ systems. The mechanisms leading to the autonomous hypersecretion of aldosterone or cortisol in aldosterone-producing adenoma (APA) or cortisol-producing adenoma (CPA) are unknown. OBJECTIVE The objective of this study was to compare the expression profiles of seve...
