Arginine-vasopressin (AVP) markedly increased basal aldosterone (ALDO) secretion by dispersed zona-glomerulosa (ZG) cells, and its effect was selectively reversed by V1-receptor antagonists (AVP-A1). Corticosterone (B) production by dispersed zona fasciculata (ZF) cells was not affected. The bolus intraperitoneal (i.p.) administration of AVP acutely raised the plasma concentrations of both ALDO...

let a; b; k 2 k and u ; v 2 u(k). we show for any idempotent e 2 k, ( a 0 b 0 ) is e-clean i ( a 0 u(vb + ka) 0 ) is e-clean and if ( a 0 b 0 ) is 0-clean, ( ua 0 u(vb + ka) 0 ) is too.

Very high frequency (VHF) nanoelectromechanical systems (NEMS) provide unprecedented sensitivity for inertial mass sensing. We demonstrate in situ measurements in real time with mass noise floor approximately 20 zg. Our best mass resolution corresponds to approximately 7 zg, equivalent to approximately 30 xenon atoms or the mass of an individual 4 kDa molecule. Detailed analysis of the ultimate...

For finite nilpotent groups G and G′, and a G-adapted ring S (the rational integers, for example), it is shown that any isomorphism between the centers of the group rings SG and SG′ is monomial, i.e., maps class sums in SG to class sums in SG′ up to multiplication with roots of unity. As a consequence, G and G′ have identical character tables if and only if the centers of their integral group r...

(see [9] and [10]). Throughout this work, we assume that the function satis®es the following conditions: (i) j …x†j …cons:† jB…x†j=jxj1‡"; where " 0 and jB…x†j is bounded and 1-periodic function on R. (ii) P n2Z …n† eÿin converges absolutely to a function that has no zeros on ‰ÿ ; Š. It is known that conditions (i) and (ii) imply that fK…x; n†; n 2 Zg is a Riesz basis on V , with a unique biort...

and Hg is open in Zg(C); τ = (τjl) a generic point on Hg, so that k(2πiτ ) can be viewed as the field of rational functions on Zg/k; Γ = a congruence subgroup of Sp2g(Z) (equivalently, a subgroup of finite index if g > 1). We recall that the symplectic group Sp2g has dimension dimSp2g = 2g 2 + g; Rw(Γ, k) = k-vector-space of k-rational modular forms of weight w (a non-negative integer) relative...
