Background: Quantitative ultrasonography of the proximal phalanges of the hand (QUS) has emerged as an attractive technical choice to assess bone quality features both in terms of bone mass and structure. Strong associations were found between QUS measures, chronological age and growth variables, such height, weight and pubertal stages. Aim: To evaluate the relationship between skeletal age and...

Hemoglobin (Hb) A2 ( 2 2) constitutes less than 3% of the total hemoglobin (Hb) in adults and has almost no physiological importance.1 On the other hand, the determination of Hb A2 is an important tool to diagnose the beta-thalassemia trait (BTT).1,2 Although individuals with BTT do not need treatment, the accurate detection of the carrier state is important in genetic counseling to determine r...

High-speed blades are often prone to fatigue due to severe blade vibrations. In particular, synchronous vibrations can cause irreversible damages to the blade. Blade tip-timing methods (BTT) have become a promising way to monitor blade vibrations. However, synchronous vibrations are unsuitably monitored by uniform BTT sampling. Therefore, non-equally mounted probes have been used, which will re...

Bacillus thuringiensis subsp. tenebrionis DSM-2803 has been studied extensively and spore/crystal mixtures of this strain are used widely in commercial products to control coleopteran pests. The endochitinase chiA Btt gene of B. thuringiensis subsp. tenebrionis DSM-2803 was cloned and expressed in Escherichia coli. The recombinant 6x-histidine tagged protein (rChiA Btt, ~74 kDa), was purified b...

Betrayal trauma theory (BTT) predicts that unawareness of abuse by someone on whom a victim is dependent may serve to protect a necessary relationship. Lindblom and Gray (2009) contribute to a growing line of BTT studies by measuring narrative detail in a sample of undergraduates who met Criterion A of the PTSD diagnosis and who rated the abuse as their most distressing trauma. Although many co...

As a first step to the control of paraplegic gait by functional electrical stimulation (FES), the control of the swinging lower leg is being studied. This paper deals with a neural control system, that has been developed for this case. The control system has been tested for a model of the swinging lower leg using computer simulations. The neural controller was trained by supervised learning (SL...

CONCLUSION The antero-posterior (AP) body tracking test (BTT) showed that the dominant foot could affect the tilt angle of the sway movement, delineated by primary component analysis. Differences associated with the dominant foot could represent the difference in space perception of each person. OBJECTIVES To examine whether the dominant foot could affect the postural control mechanism using ...

BACKGROUND The present study is designed to evaluate the reliability and cost effectiveness of cellulose acetate Hb electrophoresis and high performance liquid chromatography (HPLC) in the determination of HbA2 levels. METHODS The test population comprised 160 individuals divided into four groups: normal individuals, β-thalassemia trait (BTT) patients, iron deficiency anemia (IDA) patients, a...

Screening for β -thalassemia trait (BTT) relies on measuring hemoglobin (Hb) A2. Since multiple factors can affect HbA2 levels, the screening can become unreliable. In 1356 healthy Arabs enrolled into a federally funded premarital BTT screening program, the effects of iron deficiency (ID), α (+)-thalassemia trait, gender, smoking, and tribalism on HbA2 were studied. The complete blood count and...

INTRODUCTION Most important differential diagnosis for microcytosis and hypochromia is beta thalassemia trait (BTT) and iron deficiency anemia. AIM To study the utility of discriminant functions (DFs) and red cell indices in distinguishing BTT and iron deficiency anemia. METHODS The study is observational (cross sectional). A total of 350 patients, 43 BTT, and 307 iron-deficiency anemia ref...
