Complete temporal mode characterization of non-Gaussian states by dual homodyne measurement
Optical quantum states defined in temporal modes, especially non-Gaussian
states like photon-number states, play an important role in quantum computing
schemes. In general, the temporal-mode structures of these states are
characterized by one or more complex functions called temporal-mode functions
(TMFs). Although we can calculate TMF theoretically in some cases, experimental
estimation of TMF is more advantageous to utilize the states with high purity.
In this paper, we propose a method to estimate complex TMFs. This method can be
applied not only to arbitrary single-temporal-mode non-Gaussian states but also
to two-temporal-mode states containing two photons. This method is implemented
by continuous-wave (CW) dual homodyne measurement and doesn't need prior
information of the target states nor state reconstruction procedure. We
demonstrate this method by analyzing several experimentally created
non-Gaussian states
Stent-graft detachment from aortic wall after stent-graft repair of acute aortic dissection
AbstractPreliminary studies have demonstrated that stent-graft repair is an attractive method for treatment of aortic dissection. However, few reports have described long-term results. A 72-year-old woman with acute type B aortic dissection underwent stent-graft repair. The entry was closed, and the false lumen disappeared completely. The postoperative course was uneventful for 4 years 5 months, when detachment of the stent graft from the aortic wall was noted. Because the device appears to be stable, follow-up is on an outpatient basis
Acute and contained rupture of the descending thoracic aorta: Treatment with endovascular stent grafts
AbstractPurpose: The purpose of this study was to evaluate feasibility and safety of endovascular stent grafting for the treatment of patients with rupture of the descending thoracic aorta. Methods: Thirteen patients with rupture of the descending thoracic aorta were treated with endovascular stent grafting. Six patients were treated on the day of diagnosis because their vital signs were unstable, and the other seven patients were treated electively. Five patients had infection or potential infection, and the other eight patients did not. Expanded polytetrafluoroethylene-covered or polyester-covered Z stents were used in all patients. Results: Stent grafts were successfully placed in all patients. No endoleaks were observed at the end of the procedure. However, rebleeding was observed within 2 weeks of the procedure in two patients with infection. Six patients (46%) died within 5 months of the procedure (mean survival period, 61 ± 60 days). All five patients with infection (100%) died, and only one of eight patients without infection (13%) died (P <.01). The remaining seven patients are alive during the mean follow-up period of 21 months (overall survival rate, 54%), although additional surgical interventions, including surgical conversion in one case and upper extremity extraanatomic bypass in the other, were necessary in two of these patients. Conclusion: Endovascular stent grafting may be a safe and feasible method for the treatment of rupture of the descending thoracic aorta in selected patients without infection. However, its usefulness in terms of long-term prognosis appears to be extremely limited, especially in patients with infection. (J Vasc Surg 2003;37:100-5.

原発性シェーグレン症候群患者における再生因子REG(regenerating gene)に対する自己免疫の関与
The regenerating gene (Reg) was isolated originally as a gene specifically over-expressed in regenerating pancreatic islets and constitute a growth factor family. Reg gene product (Reg) is important in the pathophysiology of various human inflammatory diseases. Recently, the possible involvement of human REG in the regeneration of salivary ductal epithelial cells of patients with primary Sjögren's syndrome (SS) was reported. However, the expression of the REG family genes in minor salivary glands (MSG) and the occurrence of anti-REG Iα autoantibodies in SS patients were obscured. In this study, we examined the expression of REG family genes in the MSG of SS and screened anti-REG Iα autoantibodies in SS. The mRNA levels of REG family genes in MSG were quantified using real-time reverse transcription-polymerase chain reaction (RT-PCR) and REG Iα expression in the MSG was analysed by immunohistochemistry. The mRNA level of REG Iα in the MSG of SS patients was significantly higher than that of control. REG Iα protein was expressed highly in SS ductal epithelial cells. Anti-REG Iα autoantibodies in the sera were found in 11% of SS. All the MSG in the anti-REG Iα autoantibody-positive group showed REG Iα expression, whereas only 40% showed REG Iα expression in the anti-REG Iα autoantibody-negative group. The anti-REG Iα autoantibody-positive group showed significantly lower saliva secretion and a higher ratio of grade 4 (by Rubin-Holt) in sialography. These data suggest strongly that autoimmunity to REG Iα might play a role in the degeneration of MSG ductal epithelial cells in primary SS.博士(医学)・乙第1319号・平成25年11月27日The definitive version is available at " http://dx.doi.org/10.1111/cei.12142

Anthocyanins in berries of Maqui (Aristotelia chilensis (Mol.) Stuntz)
[EN] The anthocyanin composition of berries of Maqui [Aristotelia chilensis (Mol.) Stuntz] was determined by HPLC with photodiode
array and MS detection. Eight pigments corresponding to the 3-glucosides, 3,5-diglucosides, 3-sambubiosides and 3-
sambubioside-5-glucosides of delphinidin and cyanidin were identified, the principal anthocyanin being delphinidin 3-
sambubioside-5-glucoside (34% of total anthocyanins). The average total anthocyanin content was 137.6 ± 0.4 mg/100 g of
fresh fruit (211.9 ± 0.6 mg/100 g of dry fruit). The relative high anthocyanin content and the important presence of polar
polyglycosylated derivatives makes the fruits of A. chilensis an interesting source of anthocyanin extracts for food and pharmaceutical
uses
