- Objective: A pilot study performed within Stockholm County to evaluate the feasibility of collecting data using a comprehensive evaluation package administered in the home environment to assess impairment, disability and handicap in order to explore the consequences of multiple sclerosis (MS). Design: Home visits to 26 purposefully selected MS patients with different levels of disability, in both ordinary and sheltered living. The comprehensive evaluation package included: biographical data, Mini-Mental State Examination, Free Recall and Recognition of 12 Random Words Test, Symbol Digit Modalities Test, Beck Depression Index, Lindmark Motor Capacity Assessment, time to walk 10 metres, Nine-hole Peg Test, Barthel ADL Index, Katz Extended ADL Index, Frenchay Activities Index, Sickness Impact Profile and frequency of falls and injurious falls. Results: This pilot study demonstrates that the proposed methods can be used to evaluate MS patients differing in levels of disability and forms of living. The data collection method, based on home visits, was well accepted by the patients, their spouses and salaried personal assistants and could be performed within 2–21/2 hours. Conclusions: The evaluation package used in this pilot study is suitable for use in population-based studies and it should provide comprehensive information on the impact and consequences of MS on patients, and should contribute to the identification of areas in which the provision of rehabilitation and health care services needs to be improved.

Inferior mechanical properties of spastic muscle bundles due to hypertrophic but compromised extracellular matrix material
- 2003
-
Ingår i: Muscle Nerve. - 0148-639X. ; 28:4, s. 464-71

Tidskriftsartikel (refereegranskat)abstract
- The passive mechanical properties of small muscle fiber bundles obtained from surgical patients with spasticity (n = 9) and patients without neuromuscular disorders (n = 21) were measured in order to determine the relative influence of intracellular and extracellular components. For both types of patient, tangent modulus was significantly greater in bundles compared to identical tests performed on isolated single cells (P < 0.05). However, the relative difference between bundles and single cells was much greater in normal tissue than spastic tissue. The tangent modulus of normal bundles (462.5 +/- 99.6 MPa) was 16 times greater than normal single cells (28.2 +/- 3.3 MPa), whereas the tangent modulus of spastic bundles (111.2 +/- 35.5 MPa) was only twice that of spastic muscle cells (55.0 +/- 6.6 MPa). This relatively small influence of the extracellular matrix (ECM) in spastic muscle was even more surprising because spastic muscle cells occupied a significantly smaller fraction of the total specimen area (38.5 +/- 13.6%) compared to normal muscle (95.0 +/- 8.8%). Based on these data, normal muscle ECM is calculated to have a modulus of 8.7 GPa, and the ECM from spastic muscle of only 0.20 GPa. These data indicate that spastic muscle, although composed of cells that are stiffer compared to normal muscle, contains an ECM of inferior mechanical strength. The present findings illustrate some of the profound changes that occur in skeletal muscle secondary to spasticity. The surgical implications of these results are discussed.

Recension (övrigt vetenskapligt/konstnärligt)abstract
- Purpose The aim of the study was to evaluate direct astatine labelling of proteins with the use of nido-carborane as prosthetic group for attachments of astatine. Methods: Human epidermal growth factor, hEGF, was conjugated to 7-(3-amino-propyl)-7,8-dicarbanido-undecaborate (-), ANC, using two different conjugation methods, glutaraldehyde crosslinking and coupling via Traut's reagent. The hEGF-ANC conjugates were astatine labelled using the Chloramine-T method. The stability of the labelled compounds was tested by incubation at 37°C. Results: The conjugates were astatinated using the Chloramine-T method in high yield. The best labelling yields were obtained by the glutaraldehyde conjugate with an average yield of 70.5±2.2%. In vitro stability tests indicated that the introduced label was as stable as hEGF labelled with astatobenzoate. Conclusion: Conjugation of nido-carboranes to peptides creates binding sites for direct astatine labelling that can be performed in mild conditions (p 7.2) with high labelling yields.
