Forskningsöversikt (refereegranskat)abstract
- This biennial Review summarizes much of Particle Physics Using data from previous editions, plus 2205 new measurements from 667 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles All the particle properties and search limits are listed in Summary Tables We also give numerous tables, figures, formulae, and reviews of topics such as the Standard Model, particle detectors, probability, and statistics This edition features expanded coverage of CP violation in B mesons and of neutrino oscillations For the first time we cover searches for evidence of extra dimensions (both in the particle listings and in a new review) Another new review is on Grand Unified Theories A booklet is available containing the Summary Tables and abbreviated versions of some of the other sections of this full Review All tables, listings, and reviews (and errata) are also available on the Particle Data Group website http //pdg 1b1 gov.

Upregulation of Flt3 expression within the bone marrow Lin(-)Sca1(+)c-kit(+) stem cell compartment is accompanied by loss of self-renewal capacity

- Flt3 has emerged as a potential regulator of hematopoietic stem cells (HSC). Sixty percent of cells in the mouse marrow Lin(-)Sca1(+)c-kit(+) HSC pool expressed flt3. Although single cell cloning showed comparable high proliferative, myeloid, B, and T cell potentials of Lin(-)Sca1(+)c-kit(+)flt3(+) and Lin(-)Sca1(+)c-kit(+)flt3(-) cells, only Lin(-)Sca1(+)c-kit(+)flt3(-) cells supported sustained multilineage reconstitution. In striking contrast, Lin(-)Sca1(+)c-kit(+)flt3(+) cells rapidly and efficiently reconstituted B and T lymphopoiesis, whereas myeloid reconstitution was exclusively short term. Unlike c-kit, activation of flt3 failed to support survival of HSC, whereas only flt3 mediated survival of Lin(-)Sca1(+)c-kit(+)flt3(+) reconstituting cells. Phenotypic and functional analysis support that Lin(-)Sca1(+)c-kit(+)flt3(+) cells are progenitors for the common lymphoid progenitor. Thus, upregulation of flt3 expression on Lin(-)Sca1(+)c-kit(+) HSC cells is accompanied by loss of self-renewal capacity but sustained lymphoid-restricted reconstitution potential.

Bilateral caudate and putamen grafts of embryonic mesencephalic tissue treated with lazaroids in Parkinson's disease

- Five parkinsonian patients were transplanted bilaterally into the putamen and caudate nucleus with human embryonic mesencephalic tissue from between seven and nine donors. To increase graft survival, the lipid peroxidation inhibitor tirilazad mesylate was administered to the tissue before implantation and intravenously to the patients for 3 days thereafter. During the second postoperative year, the mean daily L-dopa dose was reduced by 54% and the UPDRS (Unified Parkinson's Disease Rating Scale) motor score in 'off' phase was reduced by a mean of 40%. At 10-23 months after grafting, PET showed a mean 61% increase of 6-L-[(18)F]fluorodopa uptake in the putamen, and 24% increase in the caudate nucleus, compared with preoperative values. No obvious differences in the pattern of motor recovery were observed between these and other previously studied cases with putamen grafts alone. The amount of mesencephalic tissue implanted in each putamen and caudate nucleus was 42 and 50% lower, respectively, compared with previously transplanted patients from our centre. Despite this reduction in grafted tissue, the magnitudes of symptomatic relief and graft survival were very similar. These findings suggest that tirilazad mesylate may improve survival of grafted dopamine neurons in patients, which is in agreement with observations in experimental animals.

- Severe dyskinesias during the 'off' phases (periods of increased Parkinson's disease (PD) disability) have been observed following intrastriatal transplantation of human embryonic mesencephalic tissue. Here we retrospectively analyzed 14 patients who were followed for up to 11 years after grafting, and found that dyskinesias (abnormal involuntary movements and postures) increased during postoperative off phases, but were generally of mild to moderate severity. Dyskinesia severity was not related to the magnitude of graft-derived dopaminergic re-innervation, as judged by (18)F-labeled 6-L-fluorodopa (FD) positron emission tomography (PET), indicating that off-phase dyskinesias probably did not result from excessive growth of grafted dopaminergic neurons.

Health-related quality of life following bilateral intrastriatal transplantation in Parkinson's disease

Tidskriftsartikel (refereegranskat)abstract
- Intrastriatal transplantation of embryonic dopaminergic tissue is a new, experimental approach for the treatment of Parkinson's disease (PD). Clinical trials have shown longterm graft survival and therapeutically valuable improvements with decreased L-dopa dose and time spent in the "off"-phase, and reduced rigidity and hypokinesia. We have measured health-related quality of life (HRQoL) using the Nottingham Health Profile (NHP) in five patients subjected to bilateral transplantation in the caudate and putamen to explore the influence of intrastriatal grafts on HRQoL and the value of such measures in trials of restorative therapies. The results demonstrate improved HRQoL following transplantation, with individual patients showing striking improvements within different dimensions of the NHP as well as the NHP distress index (NHPD). The most pronounced improvements after grafting were observed for physical mobility along with emotional reactions and energy. These results indicate that intrastriatal transplantation of embryonic dopaminergic tissue can give rise to improvements within most areas of HRQoL, and that HRQoL measurements provide important information additional to that obtained by traditional, symptom-oriented assessment protocols. However, the optimal approach to HRQoL measurement in PD remains to be determined.
