Causes of Melanosis other than Chlorpromazine THE pathological deposition of melanin is rarely seen in the tissues of the eye. Normally, small collections of melanin are sometimes seen in the eyes of Caucasians where the ciliary vessels pierce the sclera near the limbus. Larger collections of melanocytes form a benign naevus which may invade the cornea, or there may be multiple collections of m...

Wilson disease (WD) was a once progressive and uniformly fatal inherited disorder of copper metabolism. Medical therapy to arrest progression or prevent complications of WD was developed in the 1950s with the introduction of parenterally administered BAL [1], and over the next two decades by oral therapy with d-penicillamine, trientine, and zinc [2]. Effective therapy for WD requires life-long ...

Submitted for the MAR07 Meeting of The American Physical Society Degenerate four-wave mixing with defocusing nonlinearity JASON FLEISCHER, WENJIE WAN, SHU JIA, Princeton University — We experimentally demonstrate four-wave mixing (FWM) effects in a defocusing nonlinear photorefractive medium, in both one and two dimensions. By using a rectangular crystal, we observe the nonlinear generation of ...

in this paper, we study some ring theoretic properties of the amalgamated duplication ring $rbowtie i$ of a commutative noetherian ring $r$ along an ideal $i$ of $r$ which was introduced by d'anna and fontana. indeed, it is determined that when $rbowtie i$ satisfies serre's conditions $(r_n)$ and $(s_n)$, and when is a normal ring, a generalized cohen-macaulay ring and finally a filter ring.

in this paper, we introduce a class of $j$-quasipolar rings. let $r$ be a ring with identity. an element $a$ of a ring $r$ is called {it weakly $j$-quasipolar} if there exists $p^2 = pin comm^2(a)$ such that $a + p$ or $a-p$ are contained in $j(r)$ and the ring $r$ is called {it weakly $j$-quasipolar} if every element of $r$ is weakly $j$-quasipolar. we give many characterizations and investiga...

in this paper, we investigate various kinds of extensions of twin-good rings. moreover, we prove that every element of an abelian neat ring r is twin-good if and only if r has no factor ring isomorphic to z2  or z3. the main result of [24] states some conditions that any right self-injective ring r is twin-good. we extend this result to any regular baer ring r by proving that every element of a...
