Abstract

Fast and accurate determination of the protein content of a sample is an important and non-trivial task of many biochemical, biomedical, food chemical, pharmaceutical, and environmental research activities. Different methods of total protein determination are used for a wide range of proteins with highly variable properties in complex matrices. These methods usually work reasonably well for proteins under controlled conditions, but the results for non-standard and complex samples are often questionable. Here, we compare new and well-established methods, including traditional amino acid analysis (AAA), aromatic amino acid analysis (AAAA) based on the amino acids phenylalanine and tyrosine, reversed-phase liquid chromatography of intact proteins with UV absorbance measurements at 220 and 280 nm (LC-220, LC-280), and colorimetric assays like Coomassie Blue G-250 dye-binding assay (Bradford) and bicinchoninic acid (BCA) assay. We investigated different samples, including proteins with challenging properties, chemical modifications, mixtures, and complex matrices like air particulate matter and pollen extracts. All methods yielded accurate and precise results for the protein and matrix used for calibration. AAA, AAAA with fluorescence detection, and the LC-220 method yielded robust results even under more challenging conditions (variable analytes and matrices). These methods turned out to be well-suited for reliable determination of the protein content in a wide range of samples, such as air particulate matter and pollen., (© 2022. The Author(s).)

43. Body height loss characterizes camptocormia in Parkinson's disease.

Abstract

Axial deformities such as camptocormia or Pisa syndrome in people with Parkinson's disease (PwP) are poorly understood. The scarcity of information may result from the shortage of reliable and responsive evaluation instruments. We evaluated the body height loss (BHL) as a new measure for PwP with axial deformities. 50 PwP with axial deformity defined by an UPDRS item 28 value of at least 2 were included in this mono-center study. We measured body height while lying supine and after 1 min of standing, providing a percentage value of BHL, and compared this measure to other clinical variables. BHL depended on the Hoehn and Yahr clinical stage and correlated with clinical scales for function and mobility, but not with timely measures of the axial disorder such as age at diagnosis or duration of disease. ANOVA showed that only lumbar flexion explained the variability of BHL (F = 21.0, p < 0.0001), but not kyphosis (F = 0.4, p = 0.74) or lateroflexion (F = 0.6, p = 0.6). Re-test reliability of BHL was good with к = 0.76 (p < 0.0001). BHL resulted from the lumbar spine and the hip joint and not from the thoracic spine or lateroflexion. This observation conforms to the concept of upper-type and lower-type camptocormia with only the latter leading to a BHL. The assessment of the BHL is shown to be a well defined, easy to perform, and reliable measure for the clinical evaluation of lower-type camptocormia.
