Introduction: Tyrosinaemia type I is a rare hereditary metabolic disease caused by deficiency of the enzyme involved in the breakdown of tyrosine. Since the use of nitisinone in addition to diet in 1992, survival rates have increased significantly, but more and more socio-emotional problems have become apparent. The aim of the study was the assessment the relationship between variations in serum tyrosine and phenylalanine levels and measurements of socio-emotional functioning and determination of patients' IQs.

Measurements were made using calorimetric (ITC, DSC) and spectrophotometric (UV-Vis spectroscopy, FT-IR, H NMR) methods. The increase in the solubility in aqueous medium caused by the complexation process was determined by the Higuchi-Connors method.

Measurements were carried out using calorimetric and spectroscopic methods.

The aim of our study was to determine the relationship between parental attitudes, the development of psychological resilience, and systematic medication adherence in a group of adolescents after kidney and liver transplantation. The analysis included the results obtained from 96 families.

It compares the two groups of derivatives with regard to their intermolecular interactions in the crystal lattice and lattice energy calculations, together with energy framework visualization and global reactivity descriptors (chemical hardness, chemical potential and electrophilicity index). It also discusses the relationships between different noncovalent interactions derived from Hirshfeld surface analysis, crystal lattice energy and global reactivity descriptors of the compounds.

Fifty-four parents of children with diagnosed mucopolysaccharidosis participated in the study that was carried out during a rehabilitation programme for children with rare metabolic diseases. To assess emotional control, a Polish adaptation of the Courtauld Emotional Control Scale was used, and mood was measured with the UWIST Mood Adjective Checklist (UMACL).

Introduction: In tyrosinemia type I (TT1) increased level of tyrosine and phenylalanine (both precursors of neurotransmitters), may potentially influence patients' cognitive development.
Aim Of The Study: Was to evaluate if the children during the treatment with phenylalanine- and tyrosine-restricted diet and nitisinone present with cognitive, emotional or behavioral problems and to find out whether plasma tyrosine and phenylalanine levels may have impact on this.
Material And Methods: Cognitive development and behavior, together with plasma tyrosine and phenylalanine levels, were analyzed in eight patients during their first five years of nitisinone treatment.
Introduction: Mucopolysaccharidosis type I (MPS I) Hurler syndrome, Hurler/Scheie i Scheie is a metabolic disorder manifesting in early childhood, and characterized by the accumulation of mucopolysaccharides (glycosaminoglycans - GAG) in the cells, blood, and connective tissues. Eventually, this causes damage to cells and organs, leading to progressive impairment of the child's physical abilities, organ function, and mental development. Treatment with enzyme replacement therapy (ERT) alleviates many symptoms of the disease, however, there is no evidence indicating that ERT is effective in the prevention of nervous system degradation.
