Chadd, M. A., Gray, 0. P., and Davies, D. F. (1970). Archives of Disease in Childhood, 45, 374. Thyroid function tests in the newborn. The 131I triiodothyronine (T3) resin uptake test reflects thyroid function more closely than other acceptable tests currently available. The T3 uptake and protein-bound iodine (PBI) level were estimated in 20 premature and 20 full-term infants at birth and at th...

To evaluate the role of a circulating inhibitor of extrathyroidal conversion of T4 to T3 (IEC) in the causation of low T3 states in patients with various nonthyroidal illnesses (NTI), we measured the in vitro T3 production in the presence of ether extract of plasma. Blood samples were obtained from 22 normal subjects and 140 patients with various NTI; liver cirrhosis (LC) 37, diabetes mellitus ...

We measured serum thyroxine (free and total), triiodothyronine (free and total), thyroxine-binding globulin, and triiodothyronine uptake by talc in 97 normal men and 50 pregnant women. Mean serum thyroxine and triiodothyronine concentrations were higher in the pregnant subjects (104 vs. 78 mug/liter and 1.69 vs. 1.30 mug/liter) because of a higher mean thyroxine-binding globulin concentration (...

Background & Aim: Thymus daenensis is recognized as aromatic herbs,   which used in food, flavoring, pharmaceutical, and perfumery industries. This   study was conducted to investigate the response of T.daenensis to   different fertilizers (chemical and organic) along with chitosan.  Experimental:  Treatments consisted of different fertilizers...

It is known that some nutrients can have both negative and positive effects on some populations of insects. To test this, the Logrank test and the Interval Overlap Test were evaluated for two crop cycles (February-May and May-August) of the 7705 tomato hybrid, and the effect on the psyllid, Bactericera cockerelli (Sulc.) (Hemiptera: Triozidae), was examined under greenhouse conditions. Tomato p...

Radiolabeled triiodothyronine (T3) binding to isolated nuclei was measured to compare the binding characteristics of the nuclear receptors in rabbit ventricular and atrial muscle cells. Scatchard analysis of the binding data yielded a maximum binding capacity of 170 +/- 20 fmol per mg DNA and apparent dissociation constant of 525 +/- 100 pM for ventricular nuclei. The binding capacity and the d...

Thyroid function and serum levels of triiodothyronine (T3) and thyroxine (T4) were investigated in 79 euthyroid geriatric patients. Of the 59 inpatients and 20 outpatients 35 (59%) and 2, respectively, had low T3 levels. In contrast, 7 (12%) and 6 (30%), respectively, had raised T4 levels. Two further patients were excluded from the study because of raised levels of thyroid-stimulating hormone....

OBJECTIVE Pubertal gynaecomastia is a frequent phenomenon occurring in 20-40% of otherwise healthy adolescent boys. Little is known about the aetiology of pubertal gynaecomastia. Markedly elevated thyroid hormone levels in adults with hyperthyroidism are associated with gynaecomastia. DESIGN A cross-sectional examination of 444 healthy boys with and without pubertal gynaecomastia. METHODS W...

The influence of puberty on sweating patterns of girls exercising in the heat is not known. Nine- to 17-year-old girls, representing 4 stages of breast development: T1 (n = 21); T2 (n = 22); T3 (n = 25); and T4 (n = 22), cycled for 20 min at 60% in 35 °C. The population density of heat activated sweat glands was higher in T1 vs T3 and T4 and in T2 vs T4. Sweat drop area was lower in T1 vs T3 an...
