Abstract
This is the first report of tocilizumab-associated meningitis-retention syndrome in a patient with idiopathic multicentric Castleman disease. A 57-year-old man presented with headache, nuchal rigidity, impaired consciousness, pyramidal tract signs and urinary retention. A cerebrospinal fluid examination revealed increased cell counts and protein levels. These symptoms were improved by intravenous methylprednisolone. Tocilizumab-associated meningoencephalitis has been reported in patients with rheumatoid arthritis and juvenile idiopathic arthritis but not with multicentric Castleman disease. This case presents evidence of the increased probability of meningitis as a neurological complication of tocilizumab administration.

Abstract
BACKGROUND PET (positron emission tomography) and CSF (cerebrospinal fluid) provide the "ATN" (Amyloid, Tau, Neurodegeneration) classification and play an essential role in early and differential diagnosis of Alzheimer's disease (AD). OBJECTIVE Biomarkers were evaluated in a Japanese multicenter study on cognitively unimpaired subjects (CU) and early (E) and late (L) mild cognitive impairment (MCI) patients. MEASUREMENTS A total of 38 (26 CU, 7 EMCI, 5 LMCI) subjects with the age of 65-84 were enrolled. Amyloid-PET and FDG-PET as well as structural MRI were acquired on all of them, with an additional tau-PET with 18F-flortaucipir on 15 and CSF measurement of Aβ1-42, P-tau, and T-tau on 18 subjects. Positivity of amyloid and tau was determined based on the positive result of either PET or CSF. RESULTS The amyloid positivity was 13/38, with discordance between PET and CSF in 6/18. Cortical tau deposition quantified with PET was significantly correlated with CSF P-tau, in spite of discordance in the binary positivity between visual PET interpretation and CSF P-tau in 5/8 (PET-/CSF+). Tau was positive in 7/9 amyloid positive and 8/16 amyloid negative subjects who underwent tau measurement, respectively. Overall, a large number of subjects presented quantitative measures and/or visual read that are close to the borderline of binary positivity, which caused, at least partly, the discordance between PET and CSF in amyloid and/or tau. Nine subjects presented either tau or FDG-PET positive while amyloid was negative, suggesting the possibility of non-AD disorders. CONCLUSION Positivity rate of amyloid and tau, together with their relationship, was consistent with previous reports. Multicenter study on subjects with very mild or no cognitive impairment may need refining the positivity criteria and cutoff level as well as strict quality control of the measurements.

Abstract
A 65-year-old Japanese woman, who was diagnosed with rheumatoid arthritis and Sjögren's syndrome with various autoantibodies including anti-DNA antibody, developed bullous pemphigoid (BP) and hematological abnormalities like lupus erythematosus after adalimumab therapy. The discontinuation of adalimumab resolved those disorders but polyarthritis thereafter relapsed. The introduction of abatacept was not effective, but tocilizumab was found to be effective for polyarthritis, however, thereafter both bullous disease and severe pancytopenia developed. Discontinuation of tocilizumab was effective, but polyarthritis again developed, and baricitinib resolved it. There is an increasing number of reports of drug-induced BP and lupus erythematosus, and biologics might trigger an alteration in the pathophysiological/clinical course of rheumatic disorder.

Abstract
Background:
It has been postulated that inadequate clearance of the amyloid β protein (Aβ)
plays an important role in the accumulation of Aβ in sporadic late onset Alzheimer's disease (AD).
While the blood brain barrier (BBB) has taken the center stage in processes involving Aβ clearance, little
information is available about the role of the lymphatic system. We previously reported that Aβ is
cleared through the lymphatic system. We now assessed lymphatic Aβ clearance by treating a mouse
model of AD amyloidosis with melatonin, an Aβ aggregation inhibitor and immuno-regulatory neurohormone.
Objective:
To confirm and expand our initial finding that Aβ is cleared through the lymphatic system.
Lymphatic clearance of metabolic and cellular “waste” products from the brain into the peripheral lymphatic
system has been known for a long time. However, except for our prior report, there is no additional
experimental data published about Aβ being cleared into peripheral lymph nodes.
Methods:
For these experiments, we used a transgenic mouse model (Tg2576) that over-expresses a mutant
form of the Aβ precursor protein (APP) in the brain. We examined levels of Aβ in plasma and in
lymph nodes of transgenic mice as surrogate markers of vascular and lymphatic clearance, respectively.
Aβ levels were also measured in the brain and in multiple tissues.
Results:
Clearance of Aβ peptides through the lymphatic system was confirmed in this study. Treatment
with melatonin led to the following changes: 1-A statistically significant increase in soluble monomeric
Aβ40 and an increasing trend in Aβ42 in cervical and axillary lymph nodes of treated mice. 2-
Statistically significant decreases in oligomeric Aβ40 and a decreasing trend Aβ42 in the brain.
Conclusion:
The data expands on our prior report that the lymphatic system participates in Aβ clearance
from the brain. We propose that abnormalities in Aβ clearance through the lymphatic system may contribute
to the development of cerebral amyloidosis. Melatonin and related indole molecules (i.e., indole-
3-propionic acid) are known to inhibit Aβ aggregation although they do not reverse aggregated Aβ or
amyloid fibrils. Therefore, these substances should be further explored in prevention trials for delaying
the onset of cognitive impairment in high risk populations.

Abstract
OBJECTIVES To test the effects of bolus supplementation of branched-chain amino acids (BCAA) on skeletal muscle mass, strength, and function in patients with rheumatic disorders taking glucocorticoid (GC). METHODS Patients with rheumatic disorders treated with prednisolone (≥10 mg/day) were randomized to ingest additional daily 12 g of BCAA (n = 9) or not (n = 9) for 12 weeks. At baseline, and 4, 8, and 12 weeks, they underwent bioelectrical impedance analysis, muscle strength and functional tests, and computed tomography analysis for cross-sectional area of mid-thigh muscle. RESULTS Disease activities of the patients were well controlled and daily GC dose was similarly reduced in both groups. Limb muscle mass was recovered in both groups. Whole-body muscle mass and muscle strength and functional mobility were increased only in BCAA (+) group. The effects of BCAA supplementation on recovering skeletal muscle mass were prominent in particular muscles including biceps femoris muscle. CONCLUSIONS This trial is the first-in-man clinical trial to demonstrate that BCAA supplementation might be safe and, at least in part, improve skeletal muscle mass, strength, and function in patients with rheumatic disorders treated with GC.

Abstract
Despite the fact that phase-change materials are widely used for data storage, no consensus exists on the unique mechanism of their ultrafast phase change and its accompanied large and rapid optical change. By using the pump-probe observation method combining a femtosecond optical laser and an x-ray free-electron laser, we substantiate experimentally that, in both GeTe and Ge_{2}Sb_{2}Te_{5} crystals, rattling motion of mainly Ge atoms takes place with keeping the off-center position just after femtosecond-optical-laser irradiation, which eventually leads to a higher symmetry or disordered state. This very initial rattling motion in the undistorted lattice can be related to instantaneous optical change due to the loss of resonant bonding that characterizes GeTe-based phase change materials. Based on the amorphous structure derived by first-principles molecular dynamics simulation, we infer a plausible ultrafast amorphization mechanism via nonmelting.

Abstract
This paper aims to study the background and clinical characteristics of tacrolimus (TAC)-induced lung disease. A case of a rheumatoid arthritis (RA) patient who developed TAC-induced interstitial lung disease (TAC-ILD) is reported. The Japanese Pharmaceuticals and Medical Devices Agency (PMDA) website was searched for cases of TAC-ILD and its prevalence among all cases of TAC-related adverse events. As for cases of TAC-ILD, its underlying disease, preexisting lung diseases, and fatal outcome were also searched. Literature review of TAC-ILD cases was added. A 65-year-old female RA patient with preexisting bronchiectasis developed near-fatal TAC-ILD. Amelioration of RA, ground-glass opacities in the upper, anterior, and central lung fields, and decrease in peripheral blood lymphocyte count were the major findings in this patient. A search of the PMDA website revealed the following: the prevalence of TAC-ILD was 3 % of all cases of TAC-related adverse events, 56 out of 85 RA cases (66 %), and one out of 15 other cases had a preexisting lung disease; the prevalences of fatal outcome in RA and other cases were 24 and 38 %, respectively. A few cases in the literature had preexisting ILD and developed diffuse alveolar damage. In our case, preexisting bronchiectasis, arthritis remission, newly developed ground-glass opacities (GGOs) in the upper, anterior, and central lung fields, and decrease in peripheral blood lymphocyte count were the major findings. From the search of the PMDA website, about one fourth of the cases with TAC-related lung injury had a fatal outcome, and among RA patients, two thirds had preexisting lung diseases.

Abstract
IgG4-related pericardial involvement has rarely been reported and its clinical features remain unknown. We herein report a case of a 50-year-old woman with pericarditis who presented with a fever, elevated C-reactive protein levels, elevated serum IgG4 concentrations, and thickened pericardium with a patchy (18)F-fluorodeoxyglucose (FDG) uptake. A biopsy specimen of (18)F-FDG accumulated in the mediastinal lymph nodes revealed an abundant infiltration of IgG4-bearing plasma cells without fibrosis. Moderate-dose glucocorticoids promptly resolved the physical, serological, and imaging abnormalities, thus indicating a relatively acute and reversible nature of IgG4-related pericardial involvement.

Abstract
Catastrophic antiphospholipid syndrome (CAPS) survivors rarely relapse. We herein report a case of a second CAPS episode with an unusual subacute course and no microangiopathic hemolytic anemia (MAHA), a common CAPS symptom. During the first episode, the 69-year-old woman responded well to high-dose glucocorticoids and plasma exchange. On relapse, these treatments plus rituximab were ineffective and she died of multi-organ failure and bacterial cholangitis. The absence of MAHA and a subacute course do not exclude a CAPS recurrence.

Abstract
The diffraction anomalous fine structure (DAFS) method that is a spectroscopic analysis combined with resonant X-ray diffraction enables the determination of the valence state and local structure of a selected element at a specific crystalline site and/or phase. This method has been improved by using a polycrystalline sample, channel-cut monochromator optics with an undulator synchrotron radiation source, an area detector and direct determination of resonant terms with a logarithmic dispersion relation. This study makes the DAFS method more convenient and saves a large amount of measurement time in comparison with the conventional DAFS method with a single crystal. The improved DAFS method has been applied to some model samples, Ni foil and Fe3O4 powder, to demonstrate the validity of the measurement and the analysis of the present DAFS method.

Abstract
Abstract
The structure of a new amorphous Al87Y8Ni5, indicating high strength and good ductility, was studied by anomalous X-ray scattering (AXS). For comparison, a binary amorphous Al90Y10 alloy was also investigated. The environmental radial distribution functions around Y and Ni as well as the ordinary RDF in the ternary alloy, and the environmental RDF around Y and the ordinary RDF in the binary alloy were determined. From the analysis of these RDFs it is found that the Y atoms are completely surrounded by Al in the binary alloy, and that some of these Al atoms are replaced by Ni atoms in the ternary alloy.

Abstract
Abstract
The structure of amorphous Co-ferrite film grown on a glass substrate was studied by anomalous X-ray scattering (AXS). Co atoms cannot be distinguished from Fe atoms with the usual X-ray diffraction technique. Therefore the AXS method at the Fe and Co K-absorption edges was adopted. In the previous AXS studies only the lower energy side of the absorption edges was adopted. In the previous AXS studies only the lower energy side of the absorption edge was used. In the present case, the lower energy side of the Co K-absorption edge corresponds to the higher energy side of the Fe K-absorption edge. Therefore, in order to overcome this inconvenience, the scattering was measured on both sides of the absorption edge, thus enabling the independent determination of the oxygen coordination numbers around Co and Fe in the ferrite film from the environmental RDFs estimated from the energy differential profiles by coupling with the linear least squares technique.

Abstract
The newly installed BL28XU beamline at SPring-8 is dedicated to in situ structural and electronic analysis of rechargeable batteries. It supports the time range (1 ms to 100 s) and spatial range (1 µm to 1 mm) needed for battery analysis. Electrochemical apparatus for battery charging and discharging are available in experimental hutches and in a preparation room. Battery analysis can be carried out efficiently and effectively using X-ray diffraction, X-ray absorption fine-structure analysis and hard X-ray photoelectron spectroscopy. Here, the design and performance of the beamline are described, and preliminary results are presented.

Abstract
We have demonstrated that a photoconductive antenna gated with 5-fs ultrashort laser pulses can detect electric field transients of near-infrared pulses at least up to 180 THz. Measured sensitivity spectrum of the antenna shows a good agreement with a simple calculation, demonstrating the promising capability of the antenna to near infrared spectroscopy. Using this setup, near-infrared time-domain spectroscopy and characterization of phase controlled near-infrared pulses are demonstrated. Observed absorption spectrum of a polystyrene film and complex refractive index dispersion of a fused silica plate both agree well with those obtained by the conventional methods.

Abstract
A unique sib pair afflicted by limb girdle muscular dystrophy type 2A (LGMD2A) is described showing a slowly progressive autosomal recessive type of muscular dystrophy with onset in the third and fourth decades. The patients had early asymmetric muscle involvement characterized by prominent biceps brachii atrophy with sparing of the knee extensors. Additional findings included elevation of serum creatine kinase level, myopathic EMG changes and dystrophic type of pathology on muscle biopsy. Asymmetrical wasting of muscles in the extremities exhibited uniform and highly selective CT imaging patterns. RNA and DNA analyses confirmed novel compound heterozygous mutations (R147X/L212F) in the human CAPN3 gene.

Abstract
It has been reported that the structural stability is significantly deteriorated under radio-frequency-ultrasonic perturbation at relatively low temperatures, e.g., near/below the glass transition temperature T(g), even for thermally stable metallic glasses. Here, we consider an underlying mechanism of the ultrasound-induced instability, i.e., crystallization, of a glass structure to grasp the nature of the glass-to-liquid transition of metallic glasses. Mechanical spectroscopy analysis indicates that the instability is caused by atomic motions resonant with the dynamic ultrasonic-strain field, i.e., atomic jumps associated with the beta relaxation that is usually observed for low frequencies of the order of 1 Hz at temperatures far below T(g). Such atomic motions at temperatures lower than the so-called kinetic freezing temperature T(g) originate from relatively weakly bonded (and/or low-density) regions in a nanoscale inhomogeneous microstructure of glass, which can be straightforwardly inferred from a partially crystallized microstructure obtained by annealing of a Pd-based metallic glass just below T(g) under ultrasonic perturbation. According to this nanoscale inhomogeneity concept, we can reasonably understand an intriguing characteristic feature of less-stable metallic glasses (fabricated only by rapid melt quenching) that the crystallization precedes the glass transition upon standard heating but the glass transition is observable at extremely high rates. Namely, in such less-stable metallic glasses, atomic motions are considerably active at some local regions even below the kinetic freezing temperature. Thus, the glass-to-crystal transition of less-stable metallic glasses is, in part, explained with the present nanoscale inhomogeneity concept.

Abstract
Local atomic structures in Fe(84)Nb(7)B(9) and Fe(70)Nb(10)B(20) amorphous alloys were examined by means of electron diffraction with the help of computer calculation. Electron diffraction patterns were taken by using energy-filtered transmission electron microscopy (TEM) to eliminate inelastic scattering. We constructed structure models with 5000 atoms fitting to experimental interference functions. Voronoi polyhedral analyses were performed for the obtained final structure models. Local atomic structures of the alloys were closely related to those of the crystalline phases that appeared on annealing. A difference of stability of two amorphous phases was discussed on the basis of structure models.

Abstract
By utilizing ultrasonic annealing at a temperature below (or near) the glass transition temperature Tg, we revealed a microstructural pattern of a partially crystallized Pd-based metallic glass with a high-resolution electron microscopy. On the basis of the observed microstructure, we inferred a plausible microstructural model of fragile metallic glasses composed of strongly bonded regions surrounded by weakly bonded regions (WBRs). The crystallization in WBRs at such a low temperature under the ultrasonic vibrations is caused by accumulation of atomic jumps associated with the beta relaxation being resonant with the ultrasonic strains. This microstructural model successfully illustrates a marked increase of elasticity after crystallization with a small density change and a correlation between the fragility of the liquid and the Poisson ratio of the solid.

Abstract
BACKGROUND Epidemiologic and experimental data suggest that cholesterol may play a role in the pathogenesis of AD. Modulation of cholesterolemia in transgenic animal models of AD strongly alters amyloid pathology. OBJECTIVE To determine whether a relationship exists between amyloid deposition and total cholesterolemia (TC) in the human brain. METHODS The authors reviewed autopsy cases of patients older than 40 years and correlated cholesterolemia and presence or absence of amyloid deposition (amyloid positive vs amyloid negative subjects) and cholesterolemia and amyloid load. Amyloid load in human brains was measured by immunohistochemistry and image analysis. To remove the effect of apoE isoforms on cholesterol levels, cases were genotyped and duplicate analyses were performed on apoE3/3 subjects. RESULTS Cholesterolemia correlates with presence of amyloid deposition in the youngest subjects (40 to 55 years) with early amyloid deposition (diffuse type of senile plaques) (p = 0.000 for all apoE isoforms; p = 0.009 for apoE3/3 subjects). In this group, increases in cholesterolemia from 181 to 200 almost tripled the odds for developing amyloid, independent of apoE isoform. A logistic regression model showed consistent results (McFadden rho2 = 0.445). The difference in mean TC between subjects with and without amyloid disappeared as the age of the sample increased (>55 years: p = 0.491), possibly reflecting the effect of cardiovascular deaths among other possibilities. TC and amyloid load were not linearly correlated, indicating that there are additional factors involved in amyloid accumulation. CONCLUSIONS Serum hypercholesterolemia may be an early risk factor for the development of AD amyloid pathology.

Abstract
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a rare hereditary disease characterized by recurrent transient ischemic attacks (TIA) and strokes, and vascular dementia with Notch3 gene mutations as the cause of the disease. To date, there are only a few Japanese families ever reported with a mutation in the gene. Here, we report two more Japanese CADASIL families carrying a missense mutation in the Notch3 gene (R141C) with a unique lesion in the corpus callosum. This is the first report of two unrelated Japanese CADASIL families with a R141C mutation in the Notch3 gene. Although the disease is very rare among the Japanese population, our result suggests a possible relationship of this particular mutation (R141C) with the lesions of the corpus callosum.

Abstract
We analyzed the influence of presenilins on the genetic cascades that control neuronal differentiation in Xenopus embryos. Resembling sonic hedgehog (shh) overexpression, presenilin mRNA injection reduced the number of N-tubulin+ primary neurons and modulated Gli3 and Zic2 according to their roles in activating and repressing primary neurogenesis, respectively. Presenilin increased shh expression within its normal domain, mainly in the floor plate, whereas an antisense X-presenilin-alpha morpholino oligonucleotide reduced shh expression. Both shh and presenilin promoted cell proliferation and apoptosis, but the effects of shh were widely distributed, while those resulting from presenilin injection coincided with the range of shh signaling. We suggest that presenilin may modulate primary neurogenesis, proliferation, and apoptosis in the neural plate, through the enhancement of shh signaling.

Abstract
APPsw transgenic mice (Tg2576) overproducing mutant amyloid beta protein precursor (betaAPP) show substantial brain Abeta amyloidosis and behavioural abnormalities. To clarify the subsequent abnormalities, the disappearance of neurons and synapses and dystrophic neurite formation with accumulated proteins including hyperphosphorylated tau were examined. Tg2576 demonstrated substantial giant core plaques and diffuse plaques. The number of neurons was significantly decreased in the areas containing the amyloid cores compared with all other areas and corresponding areas in non-transgenic littermates in sections visualized by Nissl plus Congo red double staining (p<0.001). The presynaptic protein alpha-synuclein and postsynaptic protein drebrin were also absent in the amyloid cores. betaAPP and presenilin-1 were accumulated in dystrophic neurites in and around the core plaques. Tau phosphorylated at five independent sites was detected in the dystrophic neurites in the amyloid cores. Thus, the giant core plaques replaced normal brain tissues and were associated with subsequent pathological features such as dystrophic neurites and the appearance of hyperphosphorylated tau. These findings suggest a potential role for brain Abeta amyloidosis in the induction of secondary pathological steps leading to mental disturbance in Alzheimer's disease.

Abstract
Decreased levels of cerebrospinal fluid (CSF) Abeta42 is a diagnostic marker of Alzheimer's disease. To clarify the biological basis of this marker, the physiological alterations of CSF Abeta40 and Abeta42 by aging were studied. CSF samples from 92 normal subjects between 8 and 89 years old were measured using a specific ELISA for Abeta40 and Abeta42(43). High concentrations of Abeta40 and Abeta42(43) in the young group, under 29 years old, changed to be at low concentrations in the adult group between 30 and 59 years old. Subsequently, the levels increased again with age. Third order regression analysis showed a significant correlation between the levels of Abeta40 and age (Y = - 169 X(3) + 3.1X(2)- 0.02X + 4135; P < 0.034) and between the levels of Abeta42(43) and age (Y = - 46 X(3) + 0.9 X(2)- 0.005X + 992; P < 0.005). The levels of CSF Abeta40 and Abeta42(43) were physiologically regulated to show a U-shaped natural course in normal aging. These findings suggested that the physiological increase of Abeta42(43) over 59 years of age is selectively inhibited in Alzheimer's disease.

Abstract
To clarify how Abeta deposits induce secondary tauopathy, the presence of phosphorylated tau, glycogen synthase kinase 3alpha (GSK3alpha), GSK3beta, cyclin-dependent kinase 5 (CDK5), mitogen-activated protein kinase (MAPK) and fyn were examined in the Tg2576 brain showing substantial brain Abeta amyloidosis and behavioral abnormalities. Phosphorylated tau at Ser199, Thr231/Ser235, Ser396 and Ser413 accumulated in the dystrophic neurites of senile plaques. The major kinase for tau phosphorylation was GSK3beta. Smaller contributions of GSK3alpha, CDK5 and MAPK were suggested. Thus, brain Abeta amyloidosis has a potential role in the induction of tauopathy leading to the mental disturbances of Alzheimer's disease.

Abstract
APPsw transgenic mice showing substantial features of brain Abeta amyloidosis such as senile plaques and behavioral abnormalities were examined by immunostaining to determine whether Abeta deposits could induce the subsequent disturbance of neurotransmitter systems including somatostatin, substance P and choline acetyltransferase (ChAT), which are prominent in the Alzheimer's disease brain. Somatostatin, substance P and ChAT disappeared in the areas of senile plaque and were accumulated in dystrophic neurites around the amyloid cores. These findings suggest a potential role of brain Abeta amyloidosis in disturbance of the neurotransmitter systems leading to memory disturbance of Alzheimer's disease.

Abstract
Apolipoprotein J (clusterin) is a ubiquitous multifunctional glycoprotein capable of interacting with a broad spectrum of molecules. In pathological conditions, it is an amyloid associated protein, co-localizing with fibrillar deposits in systemic and localized amyloid disorders. In Alzheimer's disease, the most frequent form of amyloidosis in humans and the major cause of dementia in the elderly, apoJ is present in amyloid plaques and cerebrovascular deposits but is rarely seen in NFT-containing neurons. ApoJ expression is up-regulated in a wide variety of insults and may represent a defense response against local damage to neurons. Four different mechanisms of action could be postulated to explain the role of apoJ as a neuroprotectant during cellular stress: (1) function as an anti-apoptotic signal, (2) protection against oxidative stress, (3) inhibition of the membrane attack complex of complement proteins locally activated as a result of inflammation, and (4) binding to hydrophobic regions of partially unfolded, stressed proteins, and therefore avoiding aggregation in a chaperone-like manner. This review focuses on the association of apoJ in biological fluids with Alzheimer's soluble Abeta. This interaction prevents Abeta aggregation and fibrillization and modulates its blood-brain barrier transport at the cerebrovascular endothelium.

Abstract
The inheritance of the apolipoprotein E (apoE) epsilon4 allele is a prevailing risk factor for sporadic and familial Alzheimer's disease (AD). ApoE isoforms bind directly to Alzheimer's amyloid beta (Abeta) peptides both in vitro and in vivo. Recent studies suggest that association of apoE with lipids may modulate its interaction with Abeta. We examined the binding of lipid-associated and delipidated apoE3 and apoE4 isoforms to Abeta utilizing a solid-phase binding assay and estimated the dissociation constants for the interaction of various apoE and Abeta species. Using native apoE isoforms from stably transfected RAW 264 and human embryonic kidney 293 cells, apoE3 had greater affinity than apoE4 for both Abeta1-40 and Abeta1-42. Delipidation of apoE decreased its affinity for Abeta peptides by 5-10-fold and abolished the isoform-specificity. Conversely, incorporation of apoE isoforms produced by baculovirus-infected Sf9 cells into reconstituted human high-density-lipoprotein lipoparticles restored the affinity values for Abeta peptides and resulted in preferential binding of apoE3. The data demonstrate that native lipid-associated apoE3 binds to Abeta peptides with 2-3-fold higher affinity than lipid-associated apoE4. Since the isoforms' binding efficiency correlate inversely with the risk of developing late-onset AD, the results suggest a possible involvement of apoE3 in the clearance or routing out of Abeta from the central nervous system as one of the mechanisms underlying the pathology of the disease.

Abstract
OBJECTIVES NACP/alpha-synuclein is an aetiological gene product in familial Parkinson's disease. To clarify the pathological role of NACP/alpha-synuclein in sporadic Parkinson's disease and other related disorders including diffuse Lewy body disease (DLBD) and multiple system atrophy (MSA), paraffin sections were examined immunocytochemically using anti-NACP/alpha-synuclein antibodies. METHODS A total of 58 necropsied brains, from seven patients with Parkinson's disease, five with DLBD, six with MSA, 12 with Alzheimer's disease, one with Down's syndrome, one with amyotrophic lateral sclerosis (ALS), three with ALS and dementia, one with Huntington's disease, two with progressive supranuclear palsy (PSP), one with Pick's disease, one with myotonic dystrophy, and three with late cerebellar cortical atrophy (LCCA), and 15 elderly normal controls were examined. RESULTS In addition to immunoreactive Lewy bodies, widespread accumulation of NACP/alpha-synuclein was found in neurons and astrocytes from the brainstem and basal ganglia to the cerebral cortices in Parkinson's disease/DLBD. NACP/alpha-synuclein accumulates in oligodendrocytes from the spinal cord, the brain stem to the cerebellar white matter, and inferior olivary neurons in MSA. These widespread accumulations were not seen in other types of dementia or spinocerebellar ataxia. CONCLUSION Completely different types of NACP/alpha-synuclein accumulation in Parkinson's disease/DLBD and MSA suggest that accumulation is a major step in the pathological cascade of both diseases and provides novel strategies for the development of therapies.

Abstract
In view of the importance of amyloid beta protein accumulation in Alzheimer's disease, this paper examines age-related amyloid beta protein (Abeta) deposition and accompanying cellular changes in a mouse model in vivo. Transgenic mice were studied which expressed a gene encoding 18 residues of signal peptide and 99 residues of the carboxyl-terminal fragment (CTF) of the Abeta precursor, under the control of the cytomegalovirus enhancer/chicken beta-actin promoter. In the pancreas, Abeta accumulated in an age-dependent manner. Abeta deposits appeared as early as 3 weeks of age and increased in size and number from 4 to 16 months of age. The largest Abeta deposits were observed in the transgenic pancreas at 16 and 20 months of age. Haematoxylin and eosin staining, macrophage immunostaining, and electron microscopy showed that the Abeta fibril deposits closely correlated with degeneration of pancreatic acinar cells and macrophage activation. Abeta1-42 and Abetap3E-42 were predominant components of Abeta deposits among amino- and carboxyl-terminal modified Abeta species. These findings suggest that overproduction of Abeta causes age-related accumulation of Abeta fibrils, with accompanying cellular degeneration and macrophage activation in vivo.

Abstract
In order to clarify the distribution and pathological changes of the amyloid beta protein precursor (betaAPP), 10 Alzheimer's disease (AD) brains and seven normal control brains were examined by immunocytochemistry and in situ hybridization histochemistry. All betaAPP isoforms were distributed evenly in neuronal cell bodies and their axons and dendrites. The betaAPP-positive neuronal processes showed mesh-like networks. In AD brains, betaAPP-positive neurons and mesh-like networks were generally decreased in spite of some intensely labeled neurons. All betaAPP isoforms accumulated in neuronal processes, dystrophic neurites and senile plaques. In situ hybridization histochemistry confirmed that all isoforms of betaAPP were expressed in neurons in control brains. In AD brains, the betaAPP mRNA signal was generally decreased besides some intense signal neurons corresponding to immunostaining findings. Few astrocytes expressed betaAPP. Thus, uniform expression and distribution of betaAPP were disturbed in AD brains showing uneven decreases or increases of neuronal betaAPP expression in individual neurons and betaAPP accumulation in neurons, neuronal processes and abnormal structures including dystrophic neurites, senile plaques and neurofibrillary tangles.
