Orthogonally Complete Rings [PDF]

open access: yes, 1977
In this note we continue the study of Abian's order for reduced rings initiated in papers such as [1], [5], [3], [4]. A simple proof is given of Abian's result that taking suprema commutes with ring multiplication. The properties of orthogonally complete

Acetylcholine protects mesenteric arteries against hypoxia/reoxygenation injury via inhibiting calcium-sensing receptor

open access: yesJournal of Pharmacological Sciences, 2015
The Ca2+-sensing receptor (CaSR) plays an important role in regulating vascular tone. In the present study, we investigated the positive effects of the vagal neurotransmitter acetylcholine by suppressing CaSR activation in mesenteric arteries exposed to ...

Isotropy and Factorization in Reduced Witt Rings [PDF]

open access: yes, 2001
We consider reduced Witt rings of finite chain length. We show there is a bound, in terms of the chain length and maximal signature, on the dimension of anisotropic, totally indefinite forms.

On Extended Reversible Rings [PDF]

open access: yes, 2009
An endomorphism alpha of a ring R is called right reversible if whenever ab = 0 for a, b is an element of R, then b alpha(a) = 0. A ring R is called right alpha-reversible if there exists a right reversible endomorphism alpha of R. The notion of an alpha-

Preferential vasodilator effects of levosimendan in resistance pulmonary arteries in a rodent pulmonary embolism model

open access: yesGlobal Cardiology
Background: We compared the vasoactive effects of levosimendan on isolated conduit pulmonary arteries (CPA) and resistance pulmonary arteries (RPA) versus mesenteric arteries, and we assessed the pulmonary artery (PA) vascular function and the PA ...
