SORL1 Is Genetically Associated with Late-Onset Alzheimer’s Disease in Japanese, Koreans and Caucasians

To discover susceptibility genes of late-onset Alzheimer’s disease (LOAD), we conducted a 3-stage genome-wide association study (GWAS) using three populations: Japanese from the Japanese Genetic Consortium for Alzheimer Disease (JGSCAD), Koreans, and Caucasians from the Alzheimer Disease Genetic Consortium (ADGC). In Stage 1, we evaluated data for 5,877,918 genotyped and imputed SNPs in Japanese cases (n = 1,008) and controls (n = 1,016). Genome-wide significance was observed with 12 SNPs in the APOE region. Seven SNPs from other distinct regions with p-values ,261025 were genotyped in a second Japanese sample (885 cases, 985 controls), and evidence of association was confirmed for one SORL1 SNP (rs3781834, P=7.3361027 in the combined sample). Subsequent analysis combining results for several SORL1 SNPs in the Japanese, Korean (339 cases, 1,129 controls) and Caucasians (11,840 AD cases, 10,931 controls) revealed genome wide significance with rs11218343 (P=1.7761029) and rs3781834 (P=1.0461028). SNPs in previously established AD loci in Caucasians showed strong evidence of association in Japanese including rs3851179 near PICALM (P=1.7161025) and rs744373 near BIN1 (P = 1.3961024). The associated allele for each of these SNPs was the same as in Caucasians. These data demonstrate for the first time genome-wide significance of LOAD with SORL1 and confirm the role of other known loci for LOAD in Japanese. Our study highlights the importance of examining associations in multiple ethnic populations

High-resolution seismic reflection profiling across the surface rupture associated with the 2004 Mid-Niigata Prefecture earthquake, central Japan : data acquisition and processing

The 200.4 Mid-Niigata Prefecture earthquake (Mj 6.8) generated surface ruptures along the eastern rim of the Uonuma hills. To reveal the relationship between a seismogenic source fault and surface ruptures, shallow, high-resolution seismic reflection profiling was undertaken across the surface ruptures and the active faults. The seismic source was a mini-vibrator and seismic data were recorded by a digital telemetry system. The source and receiver interval was 10 m4 The seismic data were processed using conventional CMP seismic reflection methods. The resultant depth-converted seismic section portrays an emergent thrust beneath the surface rupture associated with the Mid-Niigata Prefecture earthquake

Identification of serum proteins that bind with S100A8, S100A9 and S100A8/A9: clinical significance of using proteins for monitoring the postoperative condition of liver recipients.

BACKGROUND: Serum proteins that non-specifically bind with human S100A8/A9 (h-S100A8/A9) have been proposed. Our aim was to isolate and identify these proteins, and verify their clinical significance for monitoring the postoperative condition of liver recipients, and further to discuss the transportation of human fibronectin (h-FN) with h-S100A8/A9 and its functional role in vivo. METHODS: To isolate the serum proteins, recombinant human S100A8, S100A9 and S100A8/A9 affinity columns were used. Proteins were identified by mass spectrometry. Two enzyme-linked immunosorbent assays (ELISA) were used to measure h-S100A8/A9 and h-FN in the sera of liver recipients. Flow cytometry was employed to detect h-S100A8/A9 and h-FN on immunological cells. Western blotting was used to confirm serum constituents using antibodies specific to each constituent. RESULTS: One of the proteins was identified with h-FN, and its fluctuation pattern in the serum of the recipient was in contrast to that of CRP. Flow cytometry showed a positive reaction for h-S100A8/A9 and h-FN on neutrophils and monocytes, indicating that both proteins exist on these cells. CONCLUSIONS: The h-FN could be transported with S100A8/A9 in blood and/or on immunological cells, and effectively prevent further attack by various internal oxidants or repair damaged liver tissue in vivo

Hypogammaglobulinemia with a selective delayed recovery in memory B cells and an impaired isotype expression after rituximab administration as an adjuvant to autologous stem cell transplantation for non-Hodgkin lymphoma

Objectives: Some studies have indicated patients who received rituximab as adjuvant to stem cell transplantation had an increased risk of developing severe hypogammaglobulinemia. The mechanism of this hypogammaglobulinemia is unknown, although investigators have hypothesized a further delay in the B-cell recovery as one potential etiology. The aim of this study is to clarify the mechanism(s) of this hypogammaglobulinemia. Methods: A total of 14 patients with high-risk CD20+ lymphoma underwent an autologous peripheral blood stem cell transplantation (APBSCT). After a hematological recovery, rituximab was given weekly for up to four doses as an adjuvant therapy. Results: After a median follow up of 33.5 months, we found six patients (group A) who had hypogammaglobulinemia, while the eight other patients (group B) had normal serum immunoglobulin levels. A phenotypical analysis revealed that group A patients had already achieved B-cell recovery. However, we found a severe delay in the recovery of CD27+ memory B cells, especially in the IgD /CD27+ switched populations in group A, but CD27 negative naive B-cells reverted to a normal range in both groups. Consistent with this, reverse transcriptase-polymerase chain reaction studies with peripheral blood mononuclear cells revealed that most patients in group A lacked more than two classes of isotype transcripts. Conclusions: Abnormal repertoires and impaired isotype expression are seen in patients with common variable immunodeficiency, these data suggested that rituximab after APBSCT can affect not only the B-cell quantities, but also the recovery of the B-cell repertoires
