Analysis of powder rheometry of FT4: Effect of air flow [PDF]

open access: yesChemical Engineering Science, 2017
Understanding of particle flow behaviour as a function of strain rate is of great interest in many items of equipment of industrial processes, such as screw conveyors, impeller mixers, and feeders, etc. The traditional commercial instruments for bulk powder flow characterisation, such as shear cells, operate at low shear strain rates, and are not ...

The serum free triiodothyronine to free thyroxine ratio as a potential prognostic biomarker of chronic kidney disease in patients with glomerular crescents: A retrospective study

open access: yesFrontiers in Endocrinology, 2022
BackgroundCrescent formation indicates severe glomerular pathology, and hypothyroidism usually predicts poor prognosis for severe diseases. However, the relationship between thyroid function and the progression of chronic kidney disease (CKD) is unclear.

Analysis of powder rheometry of FT4: Effect of particle shape [PDF]

open access: yesChemical Engineering Science, 2017
Particle shape has a strong influence on bulk powder flow and its associated rheology. It promotes mechanical arching and adversely affects fast feeding and dosing. We use the FT4 powder rheometer of Freeman Technology to experimentally characterise the particle flow as a function of the shear strain rate, and to predict its dynamics for rod-shape ...

Whole-genome sequence-based analysis of thyroid function. [PDF]

open access: yes, 2015
Normal thyroid function is essential for health, but its genetic architecture remains poorly understood. Here, for the heritable thyroid traits thyrotropin (TSH) and free thyroxine (FT4), we analyse whole-genome sequence data from the UK10K project (N=2 ...

Circadian and individual variability of TSH and thyroid hormones in subjects with euthyroidism

open access: yesКлиническая и экспериментальная тиреоидология, 2010
To ivestigate circadian and individual variability of TSH, fТ4, fТ3 in subjects without evident thyroid dysfunction. 27 persons at the age of 18–60 years have been included.

Misleading FT4 measurement: Assay-dependent antibody interference [PDF]

open access: yes, 2016
Introduction: Commonly used free thyroxine (FT4) immunoassays can be falsely elevated due to interference causing misinterpreted thyroid function. We present two cases with high FT4 concentrations due to antibody interference.

Effect of excess Fluoride consumption on Urine-Serum Fluorides, Dental state and Thyroid Hormones among children in “Talab Sarai” Punjab Pakistan

open access: yesOpen Chemistry, 2020
190 children aged 7-18 years from an endemic fluorotic village “Talab Sarai (n = 130) and a non-fluorotic, control, village “Ottawa” (n = 60) were selected for comparison.

Free Thyroxine Distinguishes Subclinical Hypothyroidism From Other Aging-Related Changes in Those With Isolated Elevated Thyrotropin

open access: yesFrontiers in Endocrinology, 2022
BackgroundAlthough a finding of isolated elevated thyrotropin (TSH) often leads to treatment with thyroid hormone, it is not specific to a diagnosis of subclinical hypothyroidism, particularly in older adults.

CDC Clinical Standardization Programs (CSP) for Free Thyroxine (FT4) to Improve the Accuracy and Reliability of FT4 Measurements in Patient Care and Clinical Research [PDF]

open access: yesJournal of the Endocrine Society, 2021
Abstract Reliable FT4 measurement is critical to assess thyroid function and diagnose and treat thyroid disorders. The Partnership for the Accurate Testing of Hormones (PATH) categorizes FT4 as a biomarker in high need for standardization, and currently high inter-assay variability restricts the interpretation of FT4 results in patient ...
