B-cell lymphoma, unclassifiable, with intermediate features between those of diffuse large B-cell lymphoma (DLBCL) and Burkitt lymphoma (BL; intermediate BL/DLBCL) commonly exhibits a morphology similar to that of typical BL and an atypical immunophenotype such as diffuse and moderate-to-strong BCL2 positivity and/or a Ki67 proliferation index <90%. Alternatively, the tumor cells exhibit greate...

PURPOSE To evaluate the use of Bowman's layer (BL) vertical topographic thickness maps in diagnosing keratoconus (KC). DESIGN Prospective, case control, interventional case series. PARTICIPANTS A total of 42 eyes: 22 eyes of 15 normal subjects and 20 eyes of 15 patients with KC. INTERVENTION Bowman's layer 2-dimensional 9-mm vertical topographic thickness maps were created using custom-ma...

Although the precise etiology of most non-Hodgkin lymphomas (NHLs) is unknown, the relationship between depressed immune function and increased risk of lymphoma is well-established. One of the clearest examples is HIV, where lymphomas are AIDS-defining illnesses. However, in this issue of Blood, Guech-Ongey and colleagues present provocative and detailed data showing that the risk of Burkitt ly...

The dynamic of chromatin degradation was studied in thymocytes and LS/BL tumour cells. In permeabilised LS/BL cells, the rate of DNA degradation induced by endogenous calcium and magnesium-dependent endonuclease was approx. 25 times slower than in thymocytes. In LS/BL cells irradiation does not induce chromatin degradation. The alkylating agent TS 160 induced chromatin degradation in both LS/BL...

Pseudo-BL algebras are noncommutative generalizations of BL-algebras and they include pseudo-MV algebras, a class of structures that are categorically equivalent to l-groups with strong unit. In this paper we characterize directly indecomposable pseudo-BL algebras and we define and study different classes of these structures: local, good, perfect, peculiar, and (strongly) bipartite pseudo-BL al...

BL-algebras are algebraic structures corresponding to Hajek’s basic fuzzy logic. The aim of this paper is analyze the structure using commutative rings. Due computational considerations, we interested in finite case. We present new ways generate rings and provide summarizing statistics. Furthermore, investigated BL-rings, i.e., whose lattice ideals can be equipped with a BL-algebra. A character...

A model for ball lightning (BL) is described. It is based upon the vorton model for elementary particles, which exploits the symmetry between electricity and magnetism. The core, or driving engine, of BL in this model is comprised of a vorton-antivorton plasma. The energy of BL, which derives from nucleon decay catalyzed by this plasma, leads, through various mechanisms, to BL luminosity as wel...

The conversion of castasterone (CS) to brassinolide (BL), a Baeyer-Villiger oxidation, represents the final and rate-limiting step in the biosynthesis of BL in plants. Heterologously expressed Arabidopsis thaliana CYP85A2 in yeast mediated the conversion of CS to BL as well as the C-6 oxidation of brassinosteroids (BRs). This indicated that CYP85A2 is a bifunctional enzyme that possesses BR C-6...
