A case of asymptomatic infection of Ascaris suum identified by PCR-restriction fragment length polymorphism and DNA sequence analysis.

Human ascariasis is a soil-transmitted helminthiasis and remains a neglected tropical disease. Ascaris suum has the potential to cause cross-infections between humans and pigs. In this study, we present a rare case of a patient with asymptomatic infection by Ascaris suum.

Hepatic injury and gluconeogenesis after subcutaneous injection of monochloroacetic acid in rats.

Objective: Monochloroacetic acid (MCA) is corrosive to skin, and causes not only chemical injury but also fatal systemic poisoning. Little is known about the cause of death. We studied the acute toxicity of MCA before clinical symptoms appeared in fasting rats.

Hemodialyzability of ionizable fluoride in hemodialysis session.

The fluoride ion content in serum and in dialysate medium was determined by means of a fluoride ion-selective electrode in 29 patients undergoing hemodialysis treatment. Abnormally high serum fluoride of 65.9 +/- 28.

Effects of caffeine on microcirculation of the human ocular fundus.

Purpose: To determine the effect of caffeine on microcirculation in the human ocular fundus.

Methods: The microcirculation in the ocular fundus of 10 healthy volunteers (10 eyes) was studied using a laser speckle tissue circulation analyzer. Caffeine or placebo (100 mg) was administered orally in a double-masked manner.

Log-normal distribution of the trace element data results from a mixture of stocahstic input and deterministic internal dynamics.

In previous article, we showed a log-normal distribution of boron and lithium in human urine. This type of distribution is common in both biological and nonbiological applications. It can be observed when the effects of many independent variables are combined, each of which having any underlying distribution.
