BACKGROUND Lead exposure is known to be harmful to the male reproductive system, including impairment of fertility. However, it is unclear whether currently existing low levels of exposure have this effect. AIMS To study retrospectively current workers in lead using industries (battery manufacture, smelting, etc), and in non-lead using control industries, in four European countries, with Time...

The lll algorithm is a polynomial-time for reducing d-dimensional lattice with exponential approximation factor. Currently, the most efficient variant of lll, by Neumaier and Stehlé, has theoretical running time in $$d^4\cdot B^{1+o\left( 1\right) }$$ where B bitlength entries, but never been implemented. This work introduces new asymptotically fast, parallel, yet heuristic, reduction algorithm...

A Pseudo-Boolean constraint, PB-constraint, is a linear constraint over Boolean variables. This kind of constraints has been widely used in expressing NP-complete problems. This paper introduces a family of algorithms for translating PseudoBoolean constraints into CNF clauses. These algorithms are centered around the idea of rewriting a PB-constraint as the conjunction of a set of easier to tra...

Prussian blue nanoparticles (PB NPs), stabilized for the first time by the pi-conjugated polymer poly(4-(2,3-dihydrothieno[3,4-b][1,4]dioxin-2yl-methoxy-1-butanesulfonic acid, potassium salt) (PEDOT-S), demonstrated a novel multiple-color pH-sensing function with a redox reaction based on the electronic interaction between the PB nano-core and the PEDOT-S shell.

This survey has compared attitudes towards (endocardial) lead extraction, among European electrophysiology centres, with special attention paid to 'redundant leads'. The main findings of this survey are: (i) most of the centres performing lead extractions do so in low volume even though the number of implants may be high. (ii) Approaches to the practice of lead extraction are based largely on c...

Rescuing the function of mutant p53 protein is an attractive cancer therapeutic strategy. Using the National Cancer Institute's anticancer drug screen data, we identified two compounds from the thiosemicarbazone family that manifest increased growth inhibitory activity in mutant p53 cells, particularly for the p53(R175) mutant. Mechanistic studies reveal that NSC319726 restores WT structure and...
