A low-iodine diet consisting of maize, peas (Pisum sativum), torula yeast, meat meal, maize oil and added vitamins, minerals and amino acids was given to eight pairs of adult, common cotton-eared marmosets (Callithrix jacchus jacchus). Eight control pairs were given the same diet to which potassium iodate was added. Both groups also received low-I apple and deionized water. The diet provided ad...

SINCE the formation of the aqueous humour depends largely upon active transport across the blood-aqueous barrier (in particular the ciliary epithelium), the rate of formation will be influenced by substances which act upon the barrier by modifying its properties or behaviour. In the present paper results are presented which deal with the actions of three different types of substance, all ofwhic...

Thyrotropin (TSH) stimulates hormonogenesis using the iodate substrate and tyrosine amino acid. After various enzymatic reactions, thyroxine (T4) and triiodothyronine (T3) are released. Part of the hormone freely circulates in serum as free T3 (FT3) and free T4 (FT4). TSH is released after feedback. A study was undertaken to determine cut-off levels of FT4 to verify hypothalamic and pitutitary ...

PURPOSE To characterize histopathologic and electroretinographic (ERG) changes in the retina of pigmented rats injected with sodium iodate in order to establish a model of retinal degeneration for future cell therapy studies. METHODS In 50 male pigmented rats weighing 250-300 grams, NaIO3 was injected into the left orbital venous plexus at 40 and 60 mg/kg doses (25 eyes in each group). Fourte...

The subjects of the study were normal infants born in hospital of healthy mothers by normal delivery. The cord was clamped at once after birth. In a subsequent paper the effects of various abnormalities of birth are examined. Sodium and potassium were estimated by flame photometer in a dilution of 10 micro litres (,lI.) in 5 ml. water; chloride by iodometric titration using silver iodate; calci...

292 www.thelancet.com Vol 382 July 27, 2013 Iodine, a crucial micronutrient, is essential for thyroid hormone production and for normal in-utero neurodevelopment. During pregnancy, iodine intake must be increased by 50% because of physiological increases in maternal thyroid hormone production, an increase in maternal renal iodine losses, and fetal iodine needs for thyroid hormone production. Io...

The utility of a cationic polymer polyethylenimines (PEI) for coating some commercially available silica-based stationary phases packed in capillaries of 0.32 mm i.d. and 10 cm long was studied for the separation and direct UV detection of inorganic anions (iodate, bromate, nitrite, bromide, and nitrate ions). With a super-endcapped octadecylated silica stationary phase, which yielded the best...

Sea ice is an integral part of the earth’s climate system because it affects planetary albedo, sea-surface salinity, and the atmosphere–ocean exchange of reactive gases and aerosols. Bromine and iodine chemistry is active at polar sea ice margins with the occurrence of bromine explosions and the biological production of organoiodine from sea ice algae. Satellite measurements demonstrate that co...

In view of the importance of noi se in physiology. information processing and fi nance, studi es on chaos and noi se have been undertaken. Detailed stud ies on the lal lowing osc illatory reactions have been undertaken: (i) thi ophenol + BrO,' + H2S0~, (ii ) fruClose + BrO,' + H2S04 + Ce 4 + , and (iii ) iodate + arsenitc, wh ich can serve as a model system for thi s purposc.
