The incorporation of copper into biological macromolecules such as Cu-Zn superoxide dismutase (SOD1) is essential for the viability of most organisms. However, copper is toxic and therefore the intracellular free copper concentration is kept to an absolute minimum. Several proteins, termed metallochaperones, are charged with the responsibility of delivering copper ...

Chronic mesenteric ischemia (CMI) is the most common vascular disorder involving the intestines, however it is unusual in clinical practice. The redundancy of the visceral circulation with multiple interconnections between the superior mesenteric artery (SMA) and the inferior mesenteric artery (IMA) is the most likely explanation for the infrequent occurrence ...

Fresnel integrals corresponding to different distances can be interpreted as scaled fractional Fourier transformations observed on spherical reference surfaces. We show that by judiciously choosing sample points on these curved reference surfaces, it is possible to represent the diffracted signals in a nonredundant manner. The change in sample spacing with ...

Most clavicle fractures heal without difficulty. However, radiographic nonunion after distal clavicle fracture has been reported in 10% to 44% of patients. Type II distal clavicle fractures, which involve displacement, are associated with the highest incidence of nonunion. Several studies have questioned the clinical relevance of distal clavicle nonunion, however. ...

Cytomegalovirus (CMV) infection promotes a broad T-cell response, with the resulting memory cells displaying diverse phenotypes. CMV establishes lifelong persistence/latency, and it is thought that viral antigens expressed during this period may regulate the expansion and/or maintenance of "inflationary" CD8 T-memory populations that display an effector memory phenotype. We show ...

Crenarchaea, such as Sulfolobus acidocaldarius and Sulfolobus tokodaii, produce antimicrobial proteins called sulfolobicins. These antimicrobial proteins inhibit the growth of closely related species. Here we report the identification of the sulfolobicin-encoding genes in S. acidocaldarius. The active sulfolobicin comprises two proteins that are equipped with a classical signal sequence. These ...
