Abstract
OBJECTIVE This open-label, randomized controlled trial investigated the effects of cilnidipine, an L/N-type calcium channel blocker (CCB), in patients with chronic kidney disease (CKD). METHODS Sixty patients with CKD and well-controlled hypertension being treated with a renin- angiotensin system (RAS) inhibitor and an L-type CCB (L-CCB) were randomly assigned either to switch from the L-CCB to cilnidipine after a 4-week observation period or to continue with L-CCB treatment. Blood pressure, heart rate and renal function were monitored for 12 months. Data were available for analysis from 50 patients: 24 from the cilnidipine group and 26 from the L-CCB group. RESULTS Blood pressure was well controlled in both groups. After 12 months, proteinuria and heart rate were significantly decreased in the cilnidipine group, but proteinuria increased and heart rate remained unchanged in the L-CCB group. There was a significant positive correlation between the percentage changes in proteinuria and heart rate. CONCLUSIONS Cilnidipine has antihypertensive effects equivalent to those of L-CCBs. In patients with CKD, proteinuria can be decreased by switching from an L-CCB to cilnidipine, thereby improving renal function.

Abstract
MAVs (micro air vehicles) with a maximal dimension of 15 cm and nominal flight speeds of around 10 m s⁻¹, operate in a Reynolds number regime of 10⁵ or lower, in which most natural flyers including insects, bats and birds fly. Furthermore, due to their light weight and low flight speed, the MAVs' flight characteristics are substantially affected by environmental factors such as wind gust. Like natural flyers, the wing structures of MAVs are often flexible and tend to deform during flight. Consequently, the aero/fluid and structural dynamics of these flyers are closely linked to each other, making the entire flight vehicle difficult to analyze. We have recently developed a hummingbird-inspired, flapping flexible wing MAV with a weight of 2.4-3.0 g and a wingspan of 10-12 cm. In this study, we carry out an integrated study of the flexible wing aerodynamics of this flapping MAV by combining an in-house computational fluid dynamic (CFD) method and wind tunnel experiments. A CFD model that has a realistic wing planform and can mimic realistic flexible wing kinematics is established, which provides a quantitative prediction of unsteady aerodynamics of the four-winged MAV in terms of vortex and wake structures and their relationship with aerodynamic force generation. Wind tunnel experiments further confirm the effectiveness of the clap and fling mechanism employed in this bio-inspired MAV as well as the importance of the wing flexibility in designing small flapping-wing MAVs.

Abstract
The most recommendable MRI sequence for the morphologic assessment of the cartilage damage due to osteoarthritis (OA) is gradient echo fat suppression T1 weighted image (SPGR: Spoiled gradient recalled acquisition in the steady state, FLASH: Fast low-angle shot). For the detection of the cartilage degeneration before the morphological change, T2 mapping, dGEMRIC (delayed Gd-DTPA2-Enhanced MRI of Cartilage), and T1ρ mapping are suggested. Subchondral bone structural changes such as bone sclerosis and cyst are deeply related to the etiology of OA, and quantitative evaluation for them using MDCT (Multi-Detector row CT) and 3TMRI are suggested.

Abstract
The geometry as well as bone mineral density (BMD) of the proximal femur contributes to fracture risk. How and the extent to which they change due to natural aging is not fully understood. We assessed BMD and geometry in the femoral neck and shaft separately, in 59 normal Japanese postmenopausal women aged 54-84 years, using clinical computed tomography (CT) and commercially available software, at baseline and 2-year follow-up. This system detected significant reductions over the 2-year interval in total BMD (%change/year = -0.900 ± 0.257, p < 0.0005), cortical cross-sectional area (CSA) (-0.800 ± 0.423%/year, p < 0.05) and cortical thickness (-1.120 ± 0.453%/year, p < 0.01) in the femoral neck. In the femoral shaft, cortical BMD decreased significantly (-0.642 ± 0.188%/year, p < 0.005). Regarding biomechanical parameters in the femoral neck, the cross-sectional moment of inertia (CSMI) and section modulus (SM) decreased (-1.38 ± 3.65%/year, p < 0.01 and -1.37 ± 2.96%/year, p < 0.005) and the buckling ratio (BR) increased significantly (1.48 ± 4.81%/year, p < 0.05), whereas no changes were found in the femoral shaft. The distinct patterns of age-related changes in the geometry and biomechanical properties in the femoral neck and shaft suggest that improved geometric measures are possible with the current non-invasive method using clinical CT.

BACKGROUND There is little information regarding the clinical behaviour of hilar cholangiocarcinoma after curative resection. METHODS A retrospective study was undertaken of 79 consecutive patients with hilar cholangiocarcinoma who had undergone major hepatectomy (three or more Couinaud segments) concomitant with caudate lobectomy, and had negative resection margins. Sites of initial disease recurrence were classified as locoregional (porta hepatis) or distant (intrahepatic, peritoneal, para-aortic lymph nodal or extra-abdominal). Univariable and multivariable analyses were performed to determine the factors potentially related to recurrence. RESULTS Disease recurrence was observed in 42 (53 per cent) of the 79 patients. Cumulative recurrence rates at 3 and 4 years after surgery were 52 and 56 per cent respectively. Locoregional recurrence alone was observed in eight (10 per cent) and distant metastasis in 34 (43 per cent) of the 79 patients after R0 resection. Positive nodal involvement and high International Union Against Cancer tumour (T) stage were independent prognostic factors associated with distant metastasis. CONCLUSION Distant metastases are more common than locoregional recurrence after R0 resection for hilar cholangiocarcinoma, and associated with nodal involvement and high T stage.

Abstract
Abstract
Background: Local estrogen synthesis may play an important role of progression of breast cancer with hormone receptors. Local progression of breast cancer may depend on high concentration of estrogens and estrogen receptor status. To clarify correlation between expression levels of enzymes in breast cancer and clinicopathological parameters, we analyzed expression of steroid sulfatase(STS), estrogen sulfatase(EST), 17b-hydroxyl steroid dehydrogenase type I & II(17b-HSDI & II) and aromatase. In addition, mRNA expression of estrogens receptor alpha(ERa), estrogen receptor beta(ERb), cycline D1 and erbB2 were measured. Material and Methods: The mRNA expression levels of genes in 196 breast cancer tissues removed from surgery were assayed by RT-PCR. Results: The level of STS were significantly higher in patients with clinical stage. STS expressed none in stage 0 or I, 0.011 in stage II, and 0.013 amol/1 amol b-actin in stage 3 or 4. In addition, EST expressed 58.5 amol/1 amol b-actin in stage 2 and 36.8 in stage 3 or 4, otherwise, the expression level of EST in stage 0 or 1 revealed 15.3 amol/1 amol b-actin. There were no correlation between clinical stage and aromatase expression. Expression levels of ERa and cyclineD1 significantly correlated with protein levels of ER, and there were significant correlation between erbB2 expression and prognosis of patients. Conclusion: Up-regulation of STS play an important role in tumor progression of breast cancer.

Abstract
18-year-old male was referred to our hospital due to persistent cough. The patient was admitted for the investigation of the abnormal shadow on a chest X-ray and chest computed tomography (CT). Chest CT showed a 2.5 cm nodular shadow in the right lower lobe. Bronchofiberscopy revealed the polypoid lesion at the right lower lobe bronchus obstructing the entire lumen of B8-10. The tumor surface was smooth and rich in small vessels. Right lower lobectomy was peformed. The diagnosis of schwannoma was confirmd with the S-100 positive immunohistochemical stain. Bronchial schwannoma is relatively rare disease; less than 90 cases have been reported with respect to schwannoma of case report in Japan.

Abstract
Four known friedelane-type triterpenoids, friedelin ( 1), 3-hydroxy-D:A-friedoolean-3-en-2-one ( 2), 2beta-hydroxy-D:A-friedooleanan-3-one ( 3), and 3alpha-hydroxy-D:A-friedooleanan-2-one ( 4), and two known lupane-type triterpenoids, lupeol ( 5) and betulin ( 6), were isolated from the stem bark of Mallotus philippensis. Isolates 1 - 4 and their synthetic analogues, 3-acetoxy-D:A-friedoolean-3-en-2-one ( 2A) and 3alpha-acetoxy-D:A-friedooleanan-2-one ( 4A), were tested for their inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by 12- O-tetradecanoylphorbol 13-acetate (TPA). The inhibitory effect of compounds 2 (IC (50) = 292 mol ratio/32 pmol/TPA) and 4 (IC (50) = 288) was stronger than those of the other compounds tested and the positive control, curcumin (IC (50) = 343). Compound 4 strongly inhibited mouse skin tumor promotion in an IN VIVO two-stage carcinogenesis model. Studies have been conducted to identify the biologically active compounds extracted from the leaves, bark, and cones of trees that currently have no specific commercial use and are therefore treated as waste in the forestry industry.

Abstract
In an attempt to obtain inhibitors of hyaluronic acid (HA) binding to its receptor, CD44, we established an efficient assay method to detect and quantify binding using fluorescein-labeled HA and HEK293 cells stably expressing CD44. As a result of the screening of culture broths of microorganisms, we found fungus strain Gloeoporus dichrous SANK 30502 produced inhibitory activity in this new assay. Five compounds, F-16438 A, B, E, F and G, were isolated from the fermentation broths, and their IC50 values were determined to be 10.3, 13.5, 27.3, 12.0 and 13.0 microM, respectively. F-16438 A, B, E, F and G are the first reported inhibitors of binding HA to CD44. F-16438 A, B, E and F have novel structures.

Abstract
Two new lanostane-type triterpenoids, inonotsuoxides A (1) and B (2) along with three known lanostane-type triterpenoids, inotodiol (3), trametenolic acid (4), and lanosterol (5), were isolated from the sclerotia of Inonotus obliquus (Pers.: Fr.) (Japanese name: Kabanoanakake) (Russian name: Chaga). Their structures were determined to be 22R,25-epoxylanost-8-ene-3beta,24S-diol (1) and 22S,25-epoxylanost-8-ene-3beta,24S-diol (2) on the basis of spectral data including single crystal X-ray analysis. These compounds except for 2 were tested for their inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13-acetate (TPA), as a test for potential cancer chemopreventive agents. The most abundant triterpene, inotodiol (3), was investigated for the inhibitory effect in a two-stage carcinogenesis test on mouse skin using 7,12-dimethylbenz[a]anthracene (DMBA) as an initiator and TPA as a promoter. Compound 3 was found to exhibit the potent anti-tumor promoting activity in the in vivo carcinogenesis test.
