Copper, the highly toxic micronutrient, plays two essential roles: it is a catalytic and structural cofactor for Cu-dependent enzymes, and it acts as a secondary messenger.In the cells, copper is imported by CTR1 (high-affinity copper transporter 1), a transmembrane high-affinity copper importer, and DMT1 (divalent metal transporter).In cytosol, en

The distally based sural fasciocutaneous flap has become a main part of the reconstruction of the lower leg, heel and foot.However, perfusion problems and venous congestion have been reported.Over the past decade, several flap modifications have been reported to improve flap viability and to solve a myriad of reconstructive needs.The purpose of thi

Background.More than ten million small-scale miners (SSM) worldwide use mercury to extract gold, releasing large amounts of the toxic element into the environment.Alternatives to mercury have been suggested over the years to little avail.A group of miners in the Philippines has demonstrated that borax, when used as a flux for smelting gold out of h

This paper presents the design, fabrication, and characterization of a thermal oscillator driven by fixed DC voltages.The proposed device consists of a miniaturized ultra-sensitive temperature sensor and a microheater.The temperature sensor was fabricated by depositing acrylate-based temperature sensing material with a positive temperature coeffici

Ammonium perrhenate is widely used in Spoon alloy manufacturing, powder processing, the catalytic industry, and other fields.Recrystallization can improve the specific surface area of ammonium perrhenate, reduce its particle size, and improve its particle size distribution uniformity.Therefore, recrystallized ammonium perrhenate can obtain better a
