In Mandarin, lexical tone has been found to interact with intonational influence intonation perception, the falling T4 facilitating perception of statement/question contrast most, and rising T2 least. However, in addition four citation tones T1-T4, Mandarin “neutral tone” which marks weak, non-initial syllables that do not carry a tone. The prevailing view is neutral is, fact, phonologically to...

We study constructions and classifications of three-generation models based on magnetized $T^4$ $T^4/{Z}_2$ orbifold as candidates the compact space. focus chiral fermion zero-mode wave functions in extra dimensions. Freedoms constant gauge fields, called Scherk-Schwarz phases are taken into account. Infinite number yielded, corresponding to ways which magnetic flux can be turned on. classify t...

OBJECTIVE To determine a levothyroxine (T4) dose recommendation for the treatment of autoimmune thyroiditis (AIT)-induced hypothyroidism. METHODS T4 doses in 75 children and adolescents with newly diagnosed AIT were prospectively collected and compared to T4 doses of patients with congenital hypothyroidism (CH, n=22). RESULTS Sixty-four patients with AIT and 22 patients with CH were include...

Serum free thyroxin (FT4) was determined in 40 patients with various nonthyroidal illnesses. We studied seven methods: (1) a free thyroxin index calculated from total T4 and triiodothyronine resin uptake; (2) a free T4 index determined by enzyme inhibitor assays (Abbott's "Tetrazyme" and "Thyrozyme"); (3) a free T4 index calculated from total T4 and thyroxin-binding globulin; (4) free T4 by equ...

Excessive bias and imprecision are major analytical problems associated with some assays for free and total thyroxine (T4). Bias in free T4 methods is largely proportional to variations in serum T4 binding. In direct methods, this is attributable to requirements for substantial quantities of protein-bound T4 to replace analytical losses of free T4. In some total T4 methods, bias is inversely pr...

Mutations termed das were isolated originally (Hercules and Wiberg, 1971) as partial suppressors of mutants in phage T4 genes 46 and 47. Since mutants in genes 46, 47, and 59 exhibit both an early arrest of phage DNA synthesis and the loss of this arrest in the presence of chloramphenicol or of mutations of T4 genes 33 and 55, we asked whether a das mutation can also suppress a gene 59 mutant. ...

the present study conducted to investigate the effect of energy sources and levels on performance and breast meat amino acids profile in cobb 500 broiler chicks. a total of 600 1-day-old cobb 500 broiler chicks with an average weight of 39 ± 0.50 g were randomly divided into five treatments. each treatment was further divided into four replicates. chicks were fed a basal diet based on corn and ...

We have assessed the influence of albumin-bound thyroxin (T4) on apparent free T4 values obtained by two "unbound analog" free T4 methods (AmerlexR Free T4 and Clinical Assays one-step Free T4). We evaluated sera showing three different albumin anomalies: total hereditary analbuminemia, partially corrected analbuminemia, and familial dysalbuminemic hyperthyroxinemia, where abnormal albumin-bind...

t4 and t3, two major hormones of thyroid gland, are responsible for regulation of “basal metabolism” in the body. thyroid function is regulated primarily by variation in the pituitary tsh. in this study, about four hundred individuals were considered from four iranian populations. they were selected randomly in their cities; shiraz, mashhad, rasht, and ilam. essential family information was ask...

It is a fact of great interest that when 131I-thyroxine and 131I-triiodothyronine are exogenously given, they are highly concentrated in the anterior hypothalamus, median eminence, and hypophysis. Schittenhelm and Eisler (1932) already found that the intravenous injection of 1.0mg/kg of thyroxine (T4) into dogs, cats and rabbits elevated iodine concentration in the tuber cinereum 10times. Since...
