Enzyme immunoassay for free thyroxin.

Clinical Chemistry, 1982
Abstract We describe a mathematical model for a single-tube enzyme immunoassay for free thyroxin (FT4), involving use of a thyroxin/horseradish peroxidase (EC 1.11.1.7) conjugate that does not interact with thyroxin-binding globulin. In the presence of serum two populations of unassociated, or free, immunologically active constituents ...

Micronutrient Status in Children Suffering From Anorexia Nervosa: A Cohort of 349 Patients in a Referral Center for Eating Disorders

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is a serious illness in which more than half of all deaths are due to malnutrition. Critically low energy and protein intake are known causes of massive weight loss, whereas micronutrient deficiencies due to a low‐calorie food pattern remain poorly characterized in children with AN. Micronutrient deficiencies in

Free thyroxine or free thyroxine index?

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde, 1982
Free thyroxine (FT4) values determined by direct radio-immunoassay and the free thyroxine index (FTI) determined by indirect calculation were compared in 431 consecutive sera from patients with suspected thyroid dysfunction . Sensitivity and specificity were similar for both tests in the thyrotoxic, hypothyroid and euthyroid ranges with appropriate ...

Body composition indices align with thyroid variation in euthyroid Saudi adults: A cross-sectional study

Journal of International Medical Research
Objective Although associations between obesity and thyroid function have been widely reported, few studies have examined euthyroid (clinically normal) adults using both bioelectrical impedance-derived body composition measures and clinically accessible ...

A phenomap of TTR amyloidosis to aid diagnostic screening

ESC Heart Failure, Volume 12, Issue 2, Page 1113-1118, April 2025.
Abstract Cardiac amyloidosis due to transthyretin (ATTR) remains an underdiagnosed cause of cardiomyopathy. As awareness of the disease grows and referrals for ATTR increase, clinicians are likely to encounter more atypical forms of the condition in clinical practice.

Assessing Clinical Severity and Prognosis in Adolescents With Anorexia Nervosa and Atypical Anorexia Nervosa Using the Albumin‐Globulin Ratio

European Eating Disorders Review, EarlyView.
ABSTRACT Objective The albumin‐globulin ratio (AGR) is a biochemical marker reflecting nutritional and inflammatory status, with significant prognostic value in chronic conditions. This study examined its association with clinical/biochemical markers in adolescents with anorexia nervosa (AN) and atypical AN (AAN).

Prolactin and Triiodothyronine Modulate Seasonal Variation in Brown Adipose Tissue in Djungarian Hamsters

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Seasonal photoperiodic cycles regulate energy rheostasis in many animals. Brown adipose tissue (BAT) and the liver are key metabolic organs that show remarkable plasticity in response to photoperiodic conditions. Prolactin (PRL) and thyroid hormones are endocrine signals that transmit neural‐derived photoperiodic time measurement encoding to ...
