The expression pattern of aromatase (ARO), the enzyme converting androgens to estrogens, was analyzed in the olfactory bulb of adult male rats and was compared with the distribution of estrogen receptor beta (ERbeta), the main estrogen receptor isoform expressed in this brain region. A strong ARO immunolabeling obtained with a specificity tested antibody was observed in juxtaglomerular neurons ...

purpose: to define the demographic and clinical features of eyelid masses at a referral hospital over a 10-year period. methods: this is a retrospective record-based study on patients with eyelid masses during the above-mentioned period. data on epidemiologic and clinical features and therapeutic approaches were collected and analyzed. results: 551 patients were included in the study from which...

In the adult kidney, renin-producing cells are typically located in the walls of afferent arterioles at the transition into the glomerular capillary network. The mechanisms that are responsible for restricting renin expression to the juxtaglomerular position are largely unknown. This study showed that in mice that lack connexin 40 (Cx40), the predominant connexin of renin-producing cells, renin...

Sertoli cell tumors of the testis are extremely rare tumors with a heterogeneous pathology. Three histological variants have been described: Sertoli cell tumor not otherwise specified (NOS), large cell calcifying sertoli cell tumor and the Sclerosing Sertoli cell tumor. The sclerosing Sertoli cell tumor described herein is associated with prominent stromal sclerosis. They present as painless...

Abstract Case: 70 years old woman was pointed out for hypertension at a medical checkup and visited primary physician. Severe hypokalemia (2.4 mmol/L) noted, abdominal CT scan revealed right 99 mm diameter adrenal tumor adjacent to 80 liver tumor. She referred our hospital further management. Despite treatment with antihypertensive agents, including ARB, MRB, CCB, her blood pressure remained ar...

Accumulation of granules in the juxtaglomerular cells occurred in rats which were maintained for 5 to 6 weeks on a diet low in sodium, chloride. Cytological evidence suggests that this was probably a storage phase of secretion following a decrease in the rate of liberation of the granules. Administration of DCA (desoxycorticosterone acetate) to salt-deficient rats did not alter this appearance ...

Juxtaglomerular neurons represent one of the largest cellular populations in the mammalian olfactory bulb yet their role for signal processing remains unclear. We used two-photon imaging and electrophysiological recordings to clarify the in vivo properties of these cells and their functional organization in the juxtaglomerular space. Juxtaglomerular neurons coded for many perceptual characteris...
