Generalized Chronic Bronchiolectasis with Left Basal Bronchiectasis

Endobronchial teratoma associated with bronchiectasis and bronchiolectasis.

A teratoma in a young West Indian of Negro race is reported. The teratoma presented radiologically in the left upper lobe as an ill-defined shadow which contained a crescent-shaped translucent area and simulated a mycetoma. In addition, the left lung showed widespread nodular shadows. The left lung was resected and the teratoma was found to be endobronchial in position. This is a very rare site...

Generalized Bronchiectasis Associated with Deficiency of Cartilage

Bronchiectasis may occasionally affect almost the entire bronchial tree. Such changes can be the result either of developmental defects of the bronchial tree or of acquired inflammatory disease. For example, cystic lung and cystic bronchiectasis can result from both causes. The purpose of the present paper is to record five patients with a most unusual type of generalized bronchiectasis, and to...

On Jordan left derivations and generalized Jordan left derivations of matrix rings

Abstract. Let R be a 2-torsion free ring with identity. In this paper, first we prove that any Jordan left derivation (hence, any left derivation) on the full matrix ringMn(R) (n 2) is identically zero, and any generalized left derivation on this ring is a right centralizer. Next, we show that if R is also a prime ring and n 1, then any Jordan left derivation on the ring Tn(R) of all n×n uppe...

On generalized left (alpha, beta)-derivations in rings

Let $R$ be a 2-torsion free ring and $U$ be a square closed Lie ideal of $R$. Suppose that $alpha, beta$ are automorphisms of $R$. An additive mapping $delta: R longrightarrow R$ is said to be a Jordan left $(alpha,beta)$-derivation of $R$ if $delta(x^2)=alpha(x)delta(x)+beta(x)delta(x)$ holds for all $xin R$. In this paper it is established that if $R$ admits an additive mapping $G : Rlongrigh...
