We studied the distribution of angiotensin II (AII) receptors type 1 (AT1) and type 2 (AT2) and the effects of a low sodium intake on these two subtypes of receptors in male rat adrenals. Binding studies on adrenal slices, on cell membranes and on cell suspensions were performed using [125I]AII and specific analogs for AT1 (Losartan) and AT2 (PD 123319) receptors. The distribution of AT1 was al...

Primary aldosteronism is the most common form of secondary hypertension with hypokalemia and suppressed renin-angiotensin system caused by autonomous aldosterone production. Our aim was to compare zona glomerulosa (ZG) structure and function between control adrenals and the peritumoral tissue from patients operated on for aldosterone-producing adenoma. ZG morphology and CYP11B1, CYP11B2, and di...

In this paper a finite set of generators is given for a subgroup of finite index in the group of central units of the integral group ring of a finitely generated nilpotent group. In this paper we construct explicitly a finite set of generators for a subgroup of finite index in the centre Z(U(ZG)) of the unit group U(ZG) of the integral group ring ZG of a finitely generated nilpotent group G. Ri...

Primary aldosteronism is a common cause of hypertension, which becomes refractory if undiagnosed, but potentially curable when caused by an aldosterone-producing adenoma (APA). The discovery of somatic mutations and differences in clinical presentations led to recognition of small but common zona glomerulosa (ZG)-like adenomas, distinct from classical large zona fasciculata-like adenomas. The i...

We consider tight Gabor frames (h, a = 1, b = 1) at critical density with h of the form Z−1(Zg/|Zg|). Here Z is the standard Zak transform and g is an even, real, well-behaved window such that Zg has exactly one zero, at ( 2 , 1 2 ), in [0, 1). We show that h and its Fourier transform have maximal decay as allowed by the Balian-Low theorem. Our result illustrates a theorem of Benedetto, Czaja, ...

A G-module clearly defines a ZG-module structure on A, and a ZG-module structure on A clearly defines a G-module structure on A. The distinction will be blurred in this regard, and one often just says that A is a G-module. The free G-modules are up to isomorphism ⊕ZG with basis X. For an arbitrary G-module A, there exists a free G-module F and a surjective map ε : F A, such that G ∼= F/ ker ε. ...

where CF and VF are the filter capacitance and voltage amplitude. See Fig. 1(a). To compute the ratio Vq/VF we use voltage division. We make the crucial observation that to calculate the qubit damping we must analyze the circuit impedances at the qubit frequency. Because the qubit is off resonance from the measurement resonator, the measurement resonator’s impedance Zr is lower than the impedan...

Abstract The zonation of the human adrenal cortex has long been established morphologically and histologically as three distinct layers cells. outer zona glomerulosa (ZG) comprises densely packed cells arranged in clusters that produce aldosterone; fasciculata (ZF) is composed with large cytoplasm, containing lipid droplets radial columns synthetize cortisol; reticularis compact pigmented produ...
