We define a large class of integrable nonlinear PDE’s, k-symmetric AKS systems, whose solutions evolve on finite dimensional subalgebras of loop algebras, and linearize on an associated algebraic curve. We prove that periodicity of the associated algebraic data implies a type of quasiperiodicity for the solution, and show that the problem of isometrically immersing n-dimensional Euclidean space...

MOTIVATION The antizymes (AZ) are proteins that regulate cellular polyamine pools in metazoa. To search for remote homologs in single-celled eukaryotes, we used computer software based on hidden Markov models. The most divergent homolog detected was that of the fission yeast Schizosaccharomyces pombe. Sequence identities between S.POMBE: AZ and known AZs are as low as 18-22% in the most conserv...

Five hydrogen-oxidizing, thermophilic, strictly chemolithoautotrophic, microaerophilic strains, with similar (99-100%) 16S rRNA gene sequences were isolated from terrestrial hot springs at Furnas, São Miguel Island, Azores, Portugal. The strain, designated Az-Fu1T, was characterized. The motile, 0.9-2.0 microm rods were Gram-negative and non-sporulating. The temperature growth range was from 50...

Background Actinic keratosis (AK) is a common premalignant skin lesion, and topical 5-fluorouracil (5-FU) commonly used in field-directed therapy. However, 5-FU associated with frequent local reactions. Objective This study aimed to qualitatively assess experiences among patients AK who refuse retreatment 5-FU. Methods Semistructured interviews were conducted 10 adult participants had received ...

Our study aimed to explore the unknowns regarding absolute and relative risks of future skin cancers in patients with actinic keratoses(AKs). We performed a retrospective cohort using de-identified, random sample 4,999,999 fee-for-service Medicare beneficiaries aged ≥65 years (2009-2018). included treated AKs and, as comparator group, benign lesion seborrheic keratosis(SK). Both groups required...

I processes invariably employ interesting biochemistry,” declares Marc Kirschner (1). From this statement, one may readily conclude that antizyme (AZ) deserves our attention. AZ is the central element in a feedback loop that controls cellular polyamines. AZ is interesting for a number of reasons. First, AZ production requires the exercise of a remarkable mechanism, translational frameshifting. ...

Solid-state electron transport (ETp) via a monolayer of immobilized azurin (Az) was examined by conducting probe atomic force microscopy (CP-AFM), as a function of both temperature (248-373K) and applied tip force (6-15 nN). At low forces, ETp via holo-Az (with Cu(2+)) is temperature-independent, but thermally activated via the Cu-depleted form of Az, apo-Az. While this observation agrees with ...
