Intracytoplasmic sperm injection (ICSI) as treatment for male-factor infertility has been introduced worldwide in the past few years in many laboratories using assisted reproduction techniques. Some changes in the existing set-up are necessary before implementing this procedure. The equipment can be divided into two groups: that required for preparation of the microtools and that required for t...

Pulmonary radiofrequency ablation requires more than just interventional radiology skills. Patients must be selected carefully, and the acts that need to be done before, during, and after the procedure must be coordinated. To guarantee patient safety, radiologists need to know the variants of the technique, the precautions that must be taken, the complications that can occur, and the risks invo...

Developmental dysplasia of the hip predisposes to premature degenerative hip disease. A number of operations have been described to improve acetabular cover and have achieved varying degrees of success. We present the case of an 84-year-old woman, who underwent a shelf procedure to reconstruct a dysplastic hip 75 years ago. To date, the shelf remains intact and the hip is asymptomatic. We belie...

Background/Introduction Replacement of the aortic valve or aortic root with a pulmonary autograft (Ross procedure) and replacement of the pulmonary valve with a pulmonary allograft or xenograft and is now a widely used technique for the treatment of aortic valve disease in the children and young adult. Excellent short and midterm results have been demonstrated but there is continuing concern ab...

A show-up is an identification procedure that only presents the witness with one suspect in contrast to a lineup where the suspect is presented among a number of fillers (i.e., known innocent people). This feature makes the show-up procedure very suggestive. In this literature review, an overview of the current research about this identification procedure is presented. The different factors tha...

This summary is intended to accompany the Up-and-Down Procedure (UDP) test guideline and the AOT425StatPgm program and assist the user in interpreting its output. The conclusions in this summary are derived from applying the test procedure to many repetitions of test simulations. More extensive treatment of the simulations can be found in the report “Simulation Results for the AOT425StatPgm Pro...

In this paper, we introduce a new algebraic structure, called a UP-algebra (UP means the University of Phayao) and a concept of UP-ideals, UP-subalgebras, congruences and UP-homomorphisms in UP-algebras, and investigated some related properties of them. We also describe connections between UP-ideals, UP-subalgebras, congruences and UP-homomorphisms, and show that the notion of UP-algebras is a ...

thyroglossal duct cysts are the most common congenital anomalies in thyroid development, which in less than 1% of cases are malignant. in most cases the diagnosis is made postoperatively. up to now, a few cases have been reported which had been papillary carcinoma. controversies exist concerning its nature and treatment. we present a 30 years old woman with papillary carcinoma of thyroglossal d...
