Nano and chelated iron fertilization influences marketable yield, phytochemical properties, and antioxidant capacity of tomatoes.

Iron (Fe) is one of the limiting micronutrients essential for crop productivity. The goal of our study was to evaluate the effects of different sources and rates of Fe fertilization on the marketable yield, physical and chemical properties, and phytochemical quality of fresh market tomatoes (Solanum Lycopersicum L., cv.

Low partial pressure of oxygen causes significant and unrecognized under-recovery of glucose on blood gas analyzers.

Background: Blood gas analyzers employing glucose-oxidase biosensors under-recover glucose when pO is low. The manufacturer of the GEM®Premier™ series of analyzers introduced an algorithm to detect specimens at risk of low pO interference. We investigated the reliability of this algorithm.

Rapid automated blood sampling system for pharmacokinetics studies of cigarette smoking.

Introduction: We developed an automated sampling system to allow multiple, discrete blood samples from a human participant to be collected rapidly and immediately following cigarette smoke exposure. We reported the details of the sampling system along with the results of a pilot study for evaluation of the system.

Methods: Components of the system include silastic tubing, solenoid pinch valves, a peristaltic pump, and a fraction collector.
