Retrospective Survey and Analysis of Anaesthesia and Outcomes in Paediatric Cleft Lip or Palate Surgery in a Tertiary Care Center, Portugal.

Introduction: Orofacial clefts are the most common craniofacial abnormalities, affecting approximately one in 700 newborns each year. The anaesthetic management of these patients is challenging, including difficulties in airway approach and respiratory complications that have direct implications in the final outcome.

Aim: The present study aimed to characterize the anesthetic approach to paediatric patients undergoing cleft palate or lip surgical repair and review the perioperative anesthetic complications in a tertiary Portuguese hospital.

Cyclodextrins in Parkinson's Disease.

Parkinson's disease is a movement disorder characterized by a progressive degeneration of dopaminergic neurons that has been object of study by the scientific community through the last decades. However, nowadays there is still no treatment to cure it, although there are drugs available, with limited efficacy, to relieve the symptoms or replenish the cells with dopamine to supply the lack of dopaminergic neurons. This work was structured in two parts.

Limiting values of diffusion coefficients of glycine, alanine, α-amino butyric acid, norvaline and norleucine in a relevant physiological aqueous medium.

The side chain effect on transport in ionic aqueous salt solutions was investigated for [Formula: see text]-amino acids glycine, alanine, [Formula: see text]-amino butyric acid, norvaline, and norleucine --that together define a chemical homologous series based on the length of the characteristic side chain which increases from zero to four carbons, respectively. Binary mutual diffusion coefficients at infinitesimal concentration in aqueous solutions of NaCl (0.15 mol kg ) are measured by means of Taylor dispersion technique for this series and significant differences were found against previous published results for identical systems in pure water.

Characterization at 25 °C of sodium hyaluronate in aqueous solutions obtained by transport techniques.

Mutual diffusion coefficients, D, were determined for aqueous solutions of sodium hyaluronate (NaHy) at 25 °C and concentrations ranging from 0.00 to 1.00 g·dm(-3) using the Taylor dispersion technique.

Mass transport techniques as a tool for a better understanding of the structure of L-Dopa in aqueous solutions.

Mutual diffusion coefficients, D, densities, ρ, and viscosities, η, are reported for aqueous solutions of L-3,4-dihydroxyphenylalanine (L-Dopa) at 298.15K and 310.15K at concentrations from (0.
