Swelling of Doubly Magic ^{48}Ca Core in Ca Isotopes beyond N=28. PHYSICAL REVIEW LETTERS 2020; 124:102501. [PMID: 32216444 DOI: 10.1103/physrevlett.124.102501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/18/2019] [Revised: 12/20/2019] [Accepted: 01/30/2020] [Indexed: 06/10/2023]
Abstract
Interaction cross sections for ^{42-51}Ca on a carbon target at 280 MeV/nucleon have been measured for the first time. The neutron number dependence of derived root-mean-square matter radii shows a significant increase beyond the neutron magic number N=28. Furthermore, this enhancement of matter radii is much larger than that of the previously measured charge radii, indicating a novel growth in neutron skin thickness. A simple examination based on the Fermi-type distribution, and mean field calculations point out that this anomalous enhancement of the nuclear size beyond N=28 results from an enlargement of the core by a sudden increase in the surface diffuseness of the neutron density distribution, which implies the swelling of the bare ^{48}Ca core in Ca isotopes beyond N=28.

Abstract
PURPOSE To quantify dopaminergic neurodegeneration and iron overload in the substantia nigra pars compacta (SNpc) to evaluate Parkinson's disease (PD) using both quantitative susceptibility mapping (QSM) and neuromelanin imaging. MATERIALS AND METHODS We studied 39 PD patients (PD group) and 25 healthy controls (HC group) who underwent brain MRI with QSM and neuromelanin imaging. QSM and neuromelanin values of the SNpc were obtained using a voxel-based automated region segmentation system. The signal-to-noise ratio (SNR) of the SNpc in the neuromelanin images was calculated based on the mean value for the background region. The neuromelanin value was defined as the neuromelanin volume with an SNR higher than that of the background. The significance of the intergroup differences, and according to the severity stages in the PD group was tested for each QSM and neuromelanin value. Receiver-operating characteristic (ROC) analysis for diagnosing PD was performed for QSM and neuromelanin values. RESULTS The QSM value was significantly higher in the PD group than in the HC group (P < 0.05). The neuromelanin value was significantly smaller in the PD group than in the HC group (P < 0.05). The areas under the ROC curve were 0.68 and 0.86 for QSM and neuromelanin values, respectively. Using QSM and neuromelanin imaging to classify the PD stage was difficult. CONCLUSIONS Quantifying the SNpc alterations with our region-based approach is useful for the diagnosis of PD.

Temperature-dependent thermal behavior of impurity hydrogen trapped in vacancy-type defects in single crystal ZnO. Appl Radiat Isot 2018; 140:224-227.

Abstract
Interacting nature between impurity hydrogen atoms and vacancy-type defects in single crystal ZnO was investigated by means of positron annihilation lifetime spectroscopy. In order to clarify the observation of their thermal behavior, the sample was implanted with 1H+ using an electrostatic accelerator. After the implantation, the positron lifetime became shorter, which suggests that the hydrogen atoms were captured by zinc vacancies (VZn) to form vacancy-hydrogen complexes (VZn + nH). The complexes decompose by heat treatment: most of the hydrogen atoms gradually dissociate from VZn + nH in the temperature range 393-773 K. It was also suggested that large vacancy clusters were formed by the agglomeration of smaller clusters during the process of stepwise isochronal annealings at temperatures from 773 to 1073 K, and their decomposition took place at 1173-1373 K. Temperature-dependent thermal behaviors of hydrogen atoms and vacancy-type defects in ZnO are discussed.

Abstract
The nuclear shell structure, which originates in the nearly independent motion of nucleons in an average potential, provides an important guide for our understanding of nuclear structure and the underlying nuclear forces. Its most remarkable fingerprint is the existence of the so-called magic numbers of protons and neutrons associated with extra stability. Although the introduction of a phenomenological spin-orbit (SO) coupling force in 1949 helped in explaining the magic numbers, its origins are still open questions. Here, we present experimental evidence for the smallest SO-originated magic number (subshell closure) at the proton number six in 13-20C obtained from systematic analysis of point-proton distribution radii, electromagnetic transition rates and atomic masses of light nuclei. Performing ab initio calculations on 14,15C, we show that the observed proton distribution radii and subshell closure can be explained by the state-of-the-art nuclear theory with chiral nucleon-nucleon and three-nucleon forces, which are rooted in the quantum chromodynamics.

Abstract
PURPOSE To describe ocular manifestations in patients with microscopic polyangiitis. METHODS Two patients with microscopic polyangiitis complained of ocular symptoms and underwent ophthalmologic examinations. RESULTS An 83-year-old woman (Case 1) was diagnosed with microscopic polyangiitis, according to the general clinical findings and the presence of perinuclear pattern of antineutrophil cytoplasmic antibodies (P-ANCA). She had hypopyon iridocyclitis in the right eye and retinal cotton-wool spots in the left eye. The patient was treated with oral prednisolone and subconjunctival betamethasone. The hypopyon iridocyclitis and retinal cotton-wool spots responded. A 79-year-old man (Case 2) had bilateral scleritis. The diagnosis of microscopic polyangiitis was made based on general clinical findings and the presence of P-ANCA. Scleritis was reduced after corticosteroid treatment. CONCLUSIONS Ophthalmologists should be aware that hypopyon iridocyclitis, cotton-wool spot, and scleritis could occur in patients with microscopic polyangiitis.

Abstract
Our research goal is to measure the 7Be(d, p) reaction to shed light on the 7Li problem in the Big-Bang Nucleosynthesis. We are developing an unstable 7Be target for a high-resolution measurement of the 7Be(d, p)8Be reaction. We plan to compare two methods to producethe 7Be target: (1) Activation method, and (2) Implantation method. We performed an activation methodexperiment at the Van de Graaff at Osaka University, and obtained the cross-section data. A second experiment to obtain more accurate data will take place at the Tandem Electrostatic Accelerator, Kobe University. We have also made a 7Be target with implantation method at CRIB, Center for Nuclear Study, Univer-sity of Tokyo. An experiment to measure the (d, p) reaction with the implanted target is scheduled for 2018 at Japan Atomic Energy Agency, tandem facility.

Abstract
OBJECTIVE Lymphoedema of the extremities is a widespread pathological condition that mostly occurs as a complication of cancer resections, especially in women. Conventional therapy refers to conservative and physiotherapeutic approaches. Surgical strategies have been widely reported in the literature and are still challenging. Part of this literature focuses on the supra microsurgical lymphaticovenular anastomosis (LVA) technique. LVA is characterized by a high success rate, minimal invasivity and broad indications. Furthermore, this procedure can be performed under local anesthesia. PATIENTS AND METHODS From October 2011 through October 2014, 69 patients affected by lymphedema underwent LVA surgery in Siena University Hospital, Italy. Preoperative and postoperative evaluations were taken. RESULTS Totally, 366 anastomosis have been performed. The average rate was 5.3 anastomosis per patient. All patients registered a decrease in the size of the affected side. The average volume reduction was 50%. Patients also showed a reduction of lymphangitis episodes and reduction of compression garments class. Moreover, a satisfaction index was evaluated. The majority of patients (72.5%) was extremely satisfied of the surgery. CONCLUSIONS LVA has demonstrated to be an effective surgical strategy to treat lymphoedema, especially in secondary cases in early stages. Although LVA is widely discussed in the literature, the majority of works relates to Japanese authors and few reports exist outside Japan. This paper represents the very first retrospective analysis of the adoption of LVA technique in Italy and one of the few outside Japan.

Abstract
Ostomy has served as an effective surgery for various anorectal disfunctions. However, it must also be noted that those patients suffered greatly from stresses caused by their stoma. Many alternative therapies have been developed, but none have solved this critical issue. Meanwhile, due to the improvements in operative methods and immunosuppressive therapy, allotranplantation has gained great popularity in recent years. Therefore, we began development of an anal transplantation model. The operation was performed in six adult Wistar rats that were divided into two groups. Group 1 underwent vascular anastomoses, while group 2 did not Group 1 grafts survived, fully recovering anal function. However, many of the group 2 grafts did not survive; those that did survive showed major defects in their anus, never recovering anal function. We succeeded in establishing the rat anal transplantation model utilizing super-microsurgery. While research in anal transplantation was behind compared to that in other fields, we hope that this model will bring significant possibilities for the future.

Abstract
BACKGROUND One of the complications of lymphoedema is recurrent cellulitis. The aim was to determine whether lymphaticovenous anastomosis (LVA) was effective at reducing cellulitis in patients with lymphoedema. METHODS This was a retrospective review of patients with arm/leg lymphoedema who underwent LVA. The frequency of cellulitis was compared before and after surgery. The diagnostic criteria for cellulitis were a fever of 38·5°C or higher, and warmth/redness in the affected limb(s). RESULTS A total of 95 patients were included. The mean number of episodes of cellulitis in the year preceding surgery was 1·46, compared with 0·18 in the year after surgery (P < 0·001). CONCLUSION LVA reduced the rate of cellulitis in these patients with lymphoedema.

Abstract
The electric-field-gradient (EFG) and anisotropic chemical shift of 45Sc(Iπ = 7/2- , stable) in TiO2 crystal were determined by detecting the FT-NMR of 45Sc(0.5 atm% of Ti in TiO2) doped in TiO2 crystal at a high field of 7.0 T and 9.4 T. Using the EFG, an old β-NQR spectrum of 41Sc was reanalyzed to obtain (41Sc)/ which was combined with the renewed (45Sc) = -(23.6 0.2) fm2 to obtain (41Sc; Iπ= 7/2- , T1/2 = 0.596 s) = (15.6±0.3) fm2. Also the atomic EFG in Ca was recalculated, using a finite-element multi configuration Hartree-Fock method to renew Q(43Ca). Finally using the known hyperfine constants of 41Ca, the (41Ca) value has been renewed

Abstract
Development of efficient ion supply of (58)Fe from (58)Fe(C5H5)2, and quick switching between therapy and material science at the Heavy-Ion Medical Accelerator in Chiba realized a new (57)Mn in-beam emission Mössbauer spectroscopy measurement system. Application to simple binary chemical compounds, MgO and NaF, proved the usefulness of the system to probe chemical and physical behaviors of trace impurities in solids. Annealing of lattice defects produced by the implantation and β-decay of (57)Mn and/or γ-ray emission recoil was observed by a local probe.

Abstract
BACKGROUND The most common morbidity that results from hemophilia is bleeding-induced hemophilic arthropathy (HA), which once established may not be interrupted completely even by prophylactic clotting factor replacement. Specific therapies to oppose inflammatory cytokines, including Interleukin 6 (IL-6) receptor antagonists, have become important in the management of inflammatory arthritides. OBJECTIVES We investigated combining therapy using MR16-1, a rat IgG antibody directed against mouse IL-6 receptor (anti-IL-6R), with factor VIII (FVIII) replacement to protect against bleeding-induced arthropathy in hemophilia A mice. METHODS Three recurrent hemarthroses were induced in the knee joint capsule of FVIII knockout mice. Treatment at the time of each hemorrhage included either: no treatment; FVIII replacement given at the time of hemorrhage; FVIII replacement at hemorrhage plus anti-IL-6R as 4-weekly injections; FVIII replacement with non-specific control antibody (rat IgG); and anti-IL-6R alone without FVIII replacement. Six weeks following the first hemarthosis, joints were harvested and histopathology was scored for synovitis, for cartilage integrity and for macrophage infiltration. RESULTS Animals that received anti-IL-6R as an adjunct to FVIII replacement demonstrated the best survival and the least acute joint swelling and pathology on histologic examination of the synovium and cartilage (P < 0.05 for each parameter). All histopathologic parameters in the mice receiving FVIII+anti-IL-6R were limited and were comparable to findings in injured hemostatically normal mice. The major benefits of adjunctive anti-IL-6R were decreasing synovial hyperplasia, hemosiderin deposition and macrophage infiltration. CONCLUSIONS Short-course specific inhibition of inflammatory cytokines as an adjunct to replacement hemostasis may be an approach to minimize hemophilic joint degeneration.

Abstract
Lower limb lymphedema is difficult to prevent and diagnose early because its natural history is unclear. Therefore, the aim of this study was to clarify its pathogenesis and to identify risk factors that may lead to early diagnosis. In 29 patients, aged 25 to 74 years with cervical, uterine, or ovarian cancer who underwent pelvic lymphadenectomy, indocyanine green fluorescence lymphangiography was performed with an infrared camera system, and lymph pumping pressure was measured indirectly preoperatively, and one, two, three, and six months postoperatively. Of these 29 patients, 22 (75.9%) completed the examinations. In the non-lymphedema group, the average lymph pumping pressure did not change significantly at postoperative follow-up compared with preoperative values. On the other hand, lymph pumping pressure increased at various time points in five patients who developed early lymphatic changes with dermal diffusion at the level of the proximal femur. An increase in lymph flow path resistance due to pelvic lymphadenectomy resulted in an initial increase in lymph pumping pressure, followed by a subsequent decrease, in the early lymphatic changes group. This trend in the pressure change signifies that the lymph vessels became dysfunctional as they were overwhelmed by the overload condition and this feature may be a clinically useful signal for the early diagnosis of developing lymphedema.

Abstract
Idiopathic lymphedema is a condition where lymph accumulates in subcutaneous tissue without a clear cause. Likewise, idiopathic portal hypertension is a syndrome where intrahepatic peripheral portal branch obstruction causes portal hypertension without a clear cause. We encountered a 37-year-old man with both idiopathic lymphedema and idiopathic portal hypertension. He had a history of right lower limb edema and epigastric varices since childhood with repeated cellulitis in the affected limb. Lymph accumulation and dilation of collateral lymph pathways in the right lower limb were observed by indocyanine green and lymphoscintigraphy, and a serpentine thoracic duct was observed using MRI. Idiopathic portal hypertension and idiopathic lymphedema were diagnosed, and peripheral lymphaticovenous anastomosis was performed for treatment of lymphedema. The limb circumference improved, and the frequency of cellulitis decreased. It is postulated that an abnormality in the embryonic cardinal vein before lymph vessel differentiation could be a possible mechanism of the dual pathologic conditions.

Lymphedema is divided into primary and secondary forms. Primary lymphedema often develops in young people and may be caused by lymphvascular aplasia, hypoplasia, and hyperplasia. The most frequent cause of secondary lymphedema after lymphatic filariasis is regional lymph node dissection for treatment of a malignant tumor, and this complication occurs most frequently in middle aged or older patients. Here, we describe a relatively young patient (27 years old) in whom collecting lymph vessels in the upper limb were disrupted by repeated self-injury, with resultant lymphedema. There have been very few reports on lymphedema caused by self-induced trauma. This case report illustrates that secondary lymphedema should also be considered and evaluated appropriately when diagnosed in a relatively young patient without a history of cancer or infection.

Regional diagnosis of lymphoedema and selection of sites for lymphaticovenular anastomosis using elastography. Clin Radiol 2011; 66:715-9. [PMID: 21524415 DOI: 10.1016/j.crad.2011.03.004] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2011] [Revised: 02/23/2011] [Accepted: 03/08/2011] [Indexed: 10/18/2022]
Abstract
AIM To evaluate the use of ultrasound elastography as a basis for determining the most appropriate sites for lymphaticovenular anastomosis (LVA) for treatment of lymphoedema. MATERIALS AND METHODS Preoperative elastography and LVA were performed in 11 patients (11 legs) with leg lymphoedema, including two cases of primary oedema and nine of secondary oedema. RESULTS The mean number of LVAs applied per leg was 4.4 (range 3-7). The mean reduction in the leg circumference was 91.7%, and 10 of the 11 cases (90.0%) were improved. Hardness was reduced from a mean of 1.6 before surgery to 0.9 after surgery, and improvement was also noted in 10 cases (90.9%). The severity of oedema was determined in five regions in each leg, and was classified as elastography stage (ES) 0 in 11 regions, ES1 in 23, ES2 in 15, and ES3 in six. CONCLUSIONS These results demonstrate the value of ultrasound elastography for the diagnosis of early-stage lymphoedema and determination of LVA sites. This is the first report of diagnosis of lymphoedema using elastography and the findings suggest that this procedure followed by LVA could be used as a new therapeutic method for early-stage lymphoedema.

Abstract
ABSTRACTIn order to assess microbial transport through compacted buffer material consisting of bentonite and silica sand with a density of 1.2, 1.6 or 1.8 g/cm3, sterilized test pieces with the diameter of 50 mm and the depth of 25 mm were fed with bacteria, Escherichia coli. The bacteria freely diffused when the proportion of Na-bentonite was 20 wt% or that of Ca-bentonite was 50 wt%. Bacterial movement was less than 5 mm in three weeks when the proportion of Na-bentonite was 70-100 wt% or that of Ca-bentonite was 100 wt%. A high proportion of bentonite is essential to slow down microbial entrance to the surface of a nuclear-waste container.

Abstract
In a co-culture of osteoclast precursor cells and synovial cells, interleukin-6 (IL-6) induces osteoclast formation. In contrast, in a monoculture of osteoclast precursor cells, IL-6 directly suppresses receptor activator for nuclear factor κB ligand (RANKL)-induced differentiation of osteoclast precursor cells into osteoclasts. In the present study, we explored why the effect of IL-6 differed between the monoculture and the co-culture systems. In the monoculture, mouse osteoclast precursor cell line, RAW 264·7 (RAW) cells were cultured with soluble RANKL (sRANKL) for 24 h or 3 days. sRANKL increased both expression of osteoclastogenesis marker, tartrate-resistant acid phosphatase isoform 5b (TRAP5b) and nuclear factor of activated T cells cytoplasmic 1 (NFATc1), whereas the co-addition of IL-6 decreased them both in a dose-dependent manner. In the co-culture, RAW cells and human synovial cell line, SW982 cells were cultured with IL-6+soluble IL-6 receptor (sIL-6R) for 3 days. TRAP5b and NFATc1 expression reduced by IL-6 was increased by the addition of SW982 cells in a manner dependent upon the number of added cells. IL-6+sIL-6R treatment significantly induced RANKL production in SW982 cells, and anti-RANKL antibody inhibited IL-6+sIL-6R-induced osteoclastogenesis. SW982 cells expressed high levels of ICAM-1 originally, and ICAM-1 expression was increased significantly by IL-6+sIL-6R. Anti-ICAM-1 antibody suppressed IL-6-induced osteoclastogenesis. Finally, in the monoculture system, addition of sICAM-1 dose-dependently restored the expression of TRAP5b reduced by IL-6. Similar results were obtained when the formation of TRAP-positive multi-nuclear cells were examined using mouse bone marrow cells. In conclusion, IL-6 gave different results in the co-culture and monoculture systems because in the co-culture, ICAM-1 from the synovial cells restored osteoclastogenesis suppressed by IL-6.

Different effects of high molecular weight sodium hyaluronate and NSAID on the progression of the cartilage degeneration in rabbit OA model. Osteoarthritis Cartilage 2007; 15:543-9.

Abstract
OBJECTIVE We examined the effects of nonsteroidal anti-inflammatory drug (NSAID) and intra-articular injections of sodium hyaluronate (HA) on cartilage degeneration in rabbit knee osteoarthritis (OA) model induced by partial meniscectomy. METHODS Loxoprofen sodium (LOX) was used as the NSAID, administered p.o. once daily for 14 days at a dose of 4 mg/kg, starting from the day of meniscectomy. Suvenyl(SVE) was used as the high molecular weight HA, injected intra-articularly into injured knee every 3 days from the day of surgery. The effect on pain was assessed by an Incapacitance Tester, and the damage of cartilage was evaluated by visual assessment and histopathology at 14 days after the surgery. RESULTS Hind paw weight bearing on the injured paw decreased time-dependently in the control group. In other three groups, the decrease of hind paw weight distribution was suppressed, demonstrating an analgesic effect. Visible damage and histopathological findings of cartilage degeneration were evident in the cartilages of the control group at day 14. In the SVE group, the damaged cartilage area decreased and cartilage degeneration was ameliorated. In contrast, in the LOX group, the cartilage degeneration was augmented compared with the control group. And, this exacerbated cartilage degeneration induced by LOX was reversed by the concomitant use of SVE. CONCLUSION Our data show that the treatment with high molecular weight HA from earlier stage is strongly recommended to preserve the structure of cartilage.
