We examined the relation between chloride concentration and the area of complexed chloride of Medtronic's Cystic Fibrosis Indicator System, using a high-resolution x-y coordinated digitizer to measure the circumference of the chloride precipitation ring. These digitized points were entered directly into an IBM PC computer, where the area of the chloride precipitation was calculated with use of ...

During early development, gamma-aminobutyric acid (GABA) depolarizes and excites neurons, contrary to its typical function in the mature nervous system. As a result, developing networks are hyperexcitable and experience a spontaneous network activity that is important for several aspects of development. GABA is depolarizing because chloride is accumulated beyond its passive distribution in thes...

Corrosion induced by chloride ions becomes a critical issue for many reinforced concrete structures. The chloride ingress into concrete has been usually simplified as a di↵usion problem where the chloride concentration throughout concrete is estimated analytically. However, this simplified approach has several limitations. For instance, it does not consider chloride ingress by convection which ...

Methacholine chloride solutions, routinely used for testing bronchial hyperreactivity, have been shown to degrade over time. The data published addressing the optimal conditions for methacholine chloride storage are conflicting and incomplete. This study investigated the effects of a variety of conditions on the stability of methacholine chloride. Methacholine chloride, dissolved in phosphate b...

The Joint Transportation Research Program serves as a vehicle for INDOT collaboration with higher education institutions and industry in Indiana to facilitate innovation that results in continuous improvement in the planning, design, construction, operation, management and economic efficiency of the Indiana transportation infrastructure. NOTICE The contents of this report reflect the views of t...

Background: Cobalt (Co) is an essential trace element for mammals required for the synthesis of vitamin B12. It is not a cumulative toxin but chronic exposure induces negative effects on the organism. It was proven that cobalt passes via placenta appearing in the fetal blood and amniotic fluid and it is shown to possess an embryotoxic effect. Also, chromium (Cr) is recognized as a trace element...

Chloride channels in the kidney are involved in important physiological functions such as cell volume regulation, acidification of intracellular vesicles, and transepithelial chloride transport. Among eight mammalian CLC chloride channels expressed in the kidney, three (CLC-K1, CLC-K2, and CLC-5) were identified to be related to kidney diseases in humans or mice. CLC-K1 mediates a transepitheli...
