AR grade cobalt chloride
hexa-hydrate (CAdegCl2.6H2O) was dissolved in distilled water to prepare stock solution of cobalt (II) ions (1000 mgl-1).
These include Rosa-blu-rosa (Pink-Blue-Pink), 1967, an object imbued with cobalt chloride
, which changes color in response to shifts in atmospheric humidity, and Untitled, 1968, a large bowl of powdered sulfur and iron filings through which the curious can drag a magnetic handle to separate the two substances.
Over 60 years ago, the principle of cobalt ions upregulating the production of erythropoietin was commonly applied when cobalt chloride
(Co[Cl.sub.2]) was prescribed for anemia .
We developed an MRI marker in which cobalt chloride
(Co[Cl.sub.2]) is complexed with 6 water molecules ([H.sub.2]O) and the chelating antioxidant N-acetylcysteine (NAC).
In in vitro studies, hypoxia is generally induced by decreasing atmospheric oxygen concentrations or by utilization of mimetic chemical agents such as cobalt chloride
(Co[Cl.sub.2]) and desferrioxamine (DFO).
In this paper, the new complex of cobalt chloride
and 2, 4, 6-trimethylpyridine (TMPy, Fig.
In the present study it was observed that the peroxidase (POD) activity in tuberose spikes was the maximum in the spikes treated with cobalt chloride
(0.078) whereas the minimum in gibberellic acid (0.003) treated spikes on the 3rd day in vase (Table 1).
Stoichiometric ratio of manganese chloride, cobalt chloride
and ferric chloride were dissolved in 0.1L of demineralised water in 1:2 molar ratios.
Historically, cobalt toxicity became a recognized clinical problem after recreational consumption of beer with a foam-stabilizing agent containing cobalt sulphate or cobalt chloride
. The addition of cobalt to beer was considered to play a key role in the development of the low-output 'beer-drinkers' cardiomyopathy, first described in Quebec, Canada, in the nineteen sixties [1, 19].
In the current study, we found that sensitizations to epoxy resin, p-tert-butylphenol formaldehyde resin, colophony, nickel sulfate, and cobalt chloride
remained concomitant, and concomitant reactions were most frequent for nickel sulfate and cobalt chloride
(20.5%), p-tert-butylphenol formaldehyde resin and colophony (13.6%), and epoxy resin and p-tert-butylphenol formaldehyde resin (10.2%).
In essence, the test involves adding cobalt chloride
(approximately 1.5 equivalents per albumin molecule) to a serum sample, gently mixing, and then incubating to allow albumin cobalt binding.
