The first unequivocally successful bone marrow cell transplantation in humans was recorded in 1968 by the University of Minnesota team of Robert A. Good (Gatti et al. Lancet 2: 1366-1369, 1968). This achievement was a direct extension of mouse models of acquired immunologic tolerance that were established 15 years earlier. In contrast, organ (i.e. kidney) transplantation was accomplished precoc...

This paper deals with the question of existence of periodic solutions of nonautonomous predator–prey dynamical systems with Beddington–DeAngelis functional response. We explore the periodicity of this system on time scales. New sufficient conditions are derived for the existence of periodic solutions. These conditions extend previous results presented in [M. Bohner, M. Fan, J. Zhang, Existence ...

BACKGROUND The present study is an economic evaluation comparing transoral robotic surgery (TORS) to (chemo)radiotherapy for the management of early T-classification oropharyngeal cancer. METHODS A societal perspective was adopted. Treatment for TORS and (chemo)radiotherapy were modeled using decision analysis and recurrences were modeled over a 10 year horizon with a Markov model. Model para...

Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is an x-linked recessive disorder expressed mostly in males. Patients with G6PD deficiency may present clinically with evidence of hemolytic anemia in the neonatal period or later in life, or may remain asymptomatic. The aim of this study was to determine the incidence of G6PD deficiency in Saudi infants screened at birth. All Saudi infants bo...

Sequencing, Polymerase Chain Reaction (PCR) and Restriction Fragment Length Polymorphism (RFLP) were carried out to detect polymorphism in the last intron of the FASN gene of the Campero broiler line. The analysis of the sequences presents a G to A substitution located at base 459 of the PCR product (GenBank accession number J02839, located at base Nr. 1222), resulting in a site recognized by r...
