A colorimetric assay for convenient detection of miRNA and RNase H activity was established in a homogeneous and label-free manner based on conformational and colorimetric changes of a polythiophene derivative (PMNT) in the duplex of DNA/PMNT and triplex of DNA/miRNA/PMNT.

Let T be a weighted tree. The weight of a subtree T1 of T is defined as the product of weights of vertices and edges of T1. We obtain a linear-time algorithm to count the sum of weights of subtrees of T . As applications, we characterize the tree with the diameter at least d, which has the maximum number of subtrees, and we characterize the tree with the maximum degree at least ∆, which has the...

Electrolyte abnormalities are common in emergency medicine and can vary greatly in importance, severity, and symptoms. Asymptomatic electrolyte abnormalities can usually be gradually corrected, but those that cause alterations in consciousness or lifethreatening dysrhythmias require immediate therapy to avoid permanent sequelae or death. In some cases, therapy for lifethreatening electrolyte di...

The calibration of a liquid I-125 source in an older standard dose calibration system is presented. The calibration factor agrees well with factors established by the NIST for newer dose calibration systems. The determination of the source activity is necessary to accurately calculate the time required to deliver the prescribed dose.
