INTRODUCTION Laboratories are recommended to determine their own local reference intervals (RIs) to embrace the variations in local populations. We have assessed local RIs for thyroid function tests using two different approaches to selection of reference populations and also searched the literature for studies using the Advia Centaur methods. METHODS Two independent populations were made of ...

Iron deficiency anemia is the most common type of anemia related to malnutrition world wide. It represents a major problem in developing countries, especially in Egypt. The aim of this study was carried out to elucidate the effect of different types of oral iron therapy (used for the treatment of iron deficiency anemia) on some hormones and minerals in anemic rats. Forty weanling male Sprague-D...

Previous reports highlight the role of systemic inflammation in the genesis of non-thyroidal illness syndrome and type 2 diabetes mellitus (T2DM). Our objective was to assess whether body mass index and the low-grade systemic inflammation would be associated with changes in thyroid hormone metabolism in patients with type 2 diabetes. This was a cross-sectional study of 104 subjects; 52 patients...

ƒÊg per 100ml plasma, respectively. Mean normal fT3 and fT4, calculated from tT3, tT4 and EF values of T3 and T4, were 2.43 and 2.21mƒÊg per 100ml plasma, respectively. The fT3 values can be obtained by the present method more easily and speedily than by the method of Nauman et al. The present fT4 values, in con sideration of BEI and the percentage of T4 in plasma, represent a more accurate one...

Preface Two y ears ago at the 1994 IEEE International Conference on Robotics and Automation, we organized a workshop on visual servo c o n trol. The workshop was an overwhelming success, with over 60 participants interested in hearing about the current state of vision-based control. A short poll of participants indicated that most were viewing the workshop as a \tuto-rial" of sorts. Unfortunate...

Background: The study's objective was to evaluate and compare total serum protein, albumin, thyroid hormones in children with PEM (protein-energy malnutrition) healthy controls. Methods: In this cross-sectional study, 100 served as cases, while an equal number of age gender-matched 4 ml venous blood were taken (3 a plain vial 1 EDTA vial) immediately submitted for further investigation. SPSS so...

BACKGROUND AND AIMS Certain endocrinological disturbances are assumed to exacerbate psoriasis. In this study we compared the serum thyroid hormone levels of a group of psoriasis patients with that of a control group. METHODS The total T3 (TT3), free T3 (FT3), total T4 (TT4), free T4 (FT4) and TSH levels obtained from the sera of 103 psoriatics (37 males and 66 females) and 96 controls (40 mal...

OBJECTIVE The objective of this study was to compare newly-modified and aged chemoPET tubes, which contain no problematic surfactants, with commercially available serum blood collection tubes (BCTs) for use in analysis of cortisol, total triiodothyronine (TT3), total thyroxine (TT4), and routine clinical chemistry analytes in serum from apparently healthy volunteers and pooled quality control (...
