Abstract
Bovine IVF embryos are evaluated morphologically using light microscopy just before transfer. However, this evaluation method is subjective, and an objective method with more certainty is needed. Sugimura et al. (PLoS ONE 2012 7, e36627) reported a promising system for selecting healthy IVF bovine embryo by using time-lapse cinematography and 5 prognostic factors. This study was to investigate the efficacy of a 2-step evaluation system of IVF embryos using microscopy for selecting high developmental competence IVF embryos. Cumulus-oocyte complexes (COC) were collected by ovarian follicular aspiration (2 to 5 mm diameter) obtained from a local abattoir. The COC (n = 488) were matured in TCM-199 medium supplemented with 5% calf serum (CS) and 0.02 IU mL–1 of FSH at 38.5°C for 20 h in an atmosphere of 5% CO2 (20 COC 100 µL–1 droplets). After 10 h of gametes co-culture (5.0 × 106 sperm cells mL–1), the presumptive zygotes were cultured in 125 µL of CR1 aa medium supplemented with 5% CS in well of-the-well culture dishes (AS ONE, Japan; 25 zygotes well–1) at 38.5°C in an atmosphere of 5% CO2, 5% O2, and 90% N2 for 9 days. Two-step evaluations of embryos were done at 27 and 55 h post-IVF (hpi). In the first step of evaluation, cleavage patterns at 27 hpi were categorized as mono-cell, 2-cell with even blastomeres and without fragments (normal cleavage), 2-cell with uneven blastomeres, and ≥3 blastomeres. During the second step of evaluation, embryos were classified by their number of blastomeres (2 to 5 cells, 6 to 8 cells, and >8 cells) and the absence or presence of multiple fragments (<20 or >20%) at 55 hpi. The data were analysed by chi-square test. The blastocyst rate (BL%) of embryos cleaved before 27 hpi (56.6%, n = 106) was higher (P < 0.01) than those of embryos cleaved after 27 hpi (37.0%, n = 235). A greater percentage (P < 0.05) of 2-cell embryos with normal cleavage (68.0%, n = 50) developed to blastocysts than from with =3 blastomeres at 27 hpi (40.6%, n = 32). Superior BL% (P < 0.01) was obtained from embryos categorized as 6- to 8-cell stage (58.6%, n = 140) and >8 cell stage (70.6%, n = 25) compared with those embryos at the 2- to 5-cell stage at 55 hpi (26.1%, n = 176). Embryos with no fragments (58.0%, n = 467) had higher BL% (P < 0.01) compared with those with <20% fragments (30.7%, n = 127) and having with >20% fragments (17.5%, n = 25) at 55 hpi. The highest of BL% was observed in embryos showing a normal cleavage to 2-cells with at 27 hpi and having >6 cells with no fragments at 55 hpi (95.2%, n = 21, P < 0.01). These results demonstrate that the 2-step evaluation system at 27 and 55 hpi using microscopy is an effective method for selecting IVF embryos with high developmental competence.

Abstract
The aim of this study was to test sucrose concentrations for single-step dilution on the viability of vitrified in vitro-produced bovine embryos. Blastocysts (n = 173, 7 to 8 days after fertilization) were vitrified using the Cryotop (Kitazato, Tokyo, Japan) method placement by incubating the blastocysts in Dulbecco's phosphate buffered saline supplemented with 20% calf serum, 7.5% ethylene glycol, and 7.5% dimethyl sulfoxide for 3 min and then transferring into vitrification solution (Dulbecco's phosphate buffered saline supplemented with 20% calf serum, 16.5% ethylene glycol, 16.5% dimethyl sulfoxide, and 0.5 M sucrose). Each embryo was placed on a Cryotop with minimum volume of vitrification solution, and then the Cryotop was plunged into liquid nitrogen. Total time from placement in vitrification solution to plunging into liquid nitrogen was 1 min. The blastocysts were warmed by incubation in the single-step dilution medium for 5 min [0 M sucrose (n = 42), 0.25 M sucrose (n = 44), 0.5 M sucrose (n = 43), and 1.0 M sucrose (n = 44)] at 38.0°C. After dilution, the embryos were washed in TCM-199 supplemented with 20% calf serum and 0.1 mM β-mercaptoethanol and were cultured for 72 h in the same medium at 38.5°C in an atmosphere of 5% CO2. The rates of re-expanded blastocysts and hatched blastocysts were determined at 24 and 72 h after warming, respectively. Data were analysed using the chi-squared test. The percent of re-expanded blastocysts at 24 h after warming in dilution medium supplemented with any level of sucrose was significantly higher (P < 0.05) than in blastocysts warmed without sucrose (Table 1). The hatched blastocyst rate of embryos at 72 h after warming in dilution medium with 0.5 M sucrose was significant higher than that with no sucrose. There were no differences in hatched blastocyst rates between the sucrose concentrations supplemented to the dilution medium. These results suggest that embryos vitrified by the Cryotop method can be diluted in single-step dilution using 0.25, 0.5, or 1.0 M sucrose supplemented to the medium.

Abstract
BACKGROUND X-linked lymphoproliferative syndrome type 2 is a rare hereditary immunodeficiency caused by mutations in the XIAP gene. This immunodeficiency frequently results in hemophagocytic lymphohistiocytosis, although hypogammaglobulinemia and dysgammaglobulinemia are also common. OBJECTIVE We identified 17 patients from 12 Japanese families with mutations in XIAP. The Glu349del mutation was observed in 3 patients, each from a different family. Interestingly, these patients exhibited dysgammaglobulinemia but not hemophagocytic lymphohistiocytosis. We conducted an immunological study of patients carrying Glu349del and other mutations to elucidate the pathogenic mechanisms of dysgammaglobulinemia in patients with mutations in the XIAP gene. PATIENTS AND METHODS We performed an immunological study of 2 patients carrying the Glu349del mutation and 8 patients with other mutations. RESULTS Flow cytometry showed that the percentage of memory B cells in patients with a mutation in XIAP was lower than that observed in the healthy controls. The patients with the Glu349del mutation had a lower percentage of memory B cells than those with other mutations. Ig production was reduced in patients with the Glu349del mutation. Increased susceptibility to apoptosis was observed in the patients with other mutations. Susceptibility to apoptosis was normal in patients with Glu349del. Microarray analysis indicated that expression of Ig-related genes was reduced in patients with the Glu349del mutation and that the pattern was different from that observed in the healthy controls or patients with other mutations in XIAP. CONCLUSIONS Patients carrying the Glu349del mutation in the XIAP gene may have a clinically and immunologically distinct phenotype from patients with other XIAP mutations. The Glu349del mutation may be associated with dysgammaglobulinemia.

Abstract
We demonstrated that in vivo-matured oocytes (mOC) collected by ovum-pick up (OPU) from cows after stimulation of follicular growth (FG) are suitable for producing good quality blastocysts (BL). However, it is not known whether duration of FG affects developmental competence of mOC. The purpose of this study was to examine development of mOC after stimulation with different duration of FG. Japanese black donor cows (n = 4 per each group), were treated with a CIDR at Day 0. Follicle of diameter >8 mm were removed on Day 5. A total 20 AU of FSH was administrated to cows twice daily with decreasing doses from the evening of Day 6 to the morning of Day 10. In the conventional group (48PG), a administration of PGF2α (0.75 mg of cloprostenol), CIDR withdrawal, and administration of GnRH (0.2 mg of fertirelin acetate) were performed on the evening of Day 8, morning of Day 9, and morning of Day 10, respectively. In the experimental group (72PG), administration of PGF2a, CIDR withdrawal, and administration of GnRH were performed on the evening of Day 9, the morning of Day 10, and the morning of Day 11, respectively. The mOC were collected from follicles >5 mm by OPU at 25 to 26 h following GnRH administration. Collected mOC were inseminated with 3 × 106 sperm mL–1 in BO solution on 30 h after GnRH. After 6 h of IVF, presumptive zygotes were cultured for 168 h in 5% CS + CR1aa, using a micro-well culture dish (Dai-Nippon-Print) and time-lapse cinematography (CCM-1.4MZS; Astec) for individual embryo observation. The kinetics of early embryo was analysis by CCM-1.4 software. To assess the quality of BL, prognostic factors were used as follows: (1) less than 27 hpi (hours post-insemination) at the first cleavage (1st CD), (2) 2 blastomeres at the end of 1st CD, and (3) absence of multiple fragments at the end of the 1st CD (Sugimura et al. 2012 PLoS ONE 7, e36627; Imai et al. 2014 Reprod. Fertil. Dev. 26, 182). Data were analysed by Student's t-test or chi-square test. The number of mOC were 12.5 ± 4.7 and 10.3 ± 2.7 (means ± s.e.) oocytes per session in 48PG and 72PG. There was no significant difference in cleavage rate or BL formation rate (97.5 ± 1.5 v. 98.2 ± 1.8%, 66.3 ± 8.2 v. 66.8 ± 3.5%, respectively). The time for 1st CD was shorter in 48PG (26.1 ± 0.3 v. 27.8 ± 0.4; P < 0.01), and the rate of 1st CD less than 27 hpi was superior in 48PG compared with 72PG (74.3 v. 42.9%; P < 0.05). However, the rate of 2 blastomeres and absence of multiple fragments were not different between 48PG and 72PG. The number of BL tended to decrease in 72PG compared with 48PG (28.6 v. 48.6%; P = 0.087). These results indicate that duration of FG did not affect the rate of cleavage and BL formation. However, extension of duration of FG might reduce the quality of BL.

Abstract
PURPOSE OF INVESTIGATION Primary peritoneal carcinoma (PPC) is histologically similar to ovarian serous carcinoma, but its biochemical features remain obscure. The authors investigated and compared clinical findings, treatments, and outcomes of patients with PPS and those with epithelial ovarian cancer (EOC) patients. MATERIALS AND METHODS The authors retrospectively reviewed data from 14 patients with PPC and 219 patients with EOC treated at the present hospital from January 2005 to December 2012, including demographic data, pathologic findings, treatments, and outcomes. RESULTS Patients with PPC were significantly older (62.6 ± 8.4 years) than those with EOC (56.3 ± 11.3 years) (p = 0.045). There was no significant difference in serum CA-125 levels. The five-year survival rates did not differ significantly between patients with PPC (61.1%) and those with EOC (60.3%; p = 0.78); nor between patients with PPC and those with Stage III serous EOC (43.8%; p = 0.40). CONCLUSIONS Treatment strategies for EOC applied to PPC apparently led to similar survival patterns among the two patient groups. Cytoreductive surgery combined with pre/postoperative platinum-containing chemotherapy may be effective for PPC patients.

Abstract
The PHENIX experiment has measured open heavy-flavor production via semileptonic decay over the transverse momentum range 1 < p(T) < 6 GeV/c at forward and backward rapidity (1.4 < |y| < 2.0) in d+Au and p + p collisions at √sNN = 200 GeV. In central d+Au collisions, relative to the yield in p + p collisions scaled by the number of binary nucleon-nucleon collisions, a suppression is observed at forward rapidity (in the d-going direction) and an enhancement at backward rapidity (in the Au-going direction). Predictions using nuclear-modified-parton-distribution functions, even with additional nuclear-p(T) broadening, cannot simultaneously reproduce the data at both rapidity ranges, which implies that these models are incomplete and suggests the possible importance of final-state interactions in the asymmetric d + Au collision system. These results can be used to probe cold-nuclear-matter effects, which may significantly affect heavy-quark production, in addition to helping constrain the magnitude of charmonia-breakup effects in nuclear matter.

Abstract
Charged-pion-interferometry measurements were made with respect to the second- and third-order event plane for Au+Au collisions at sqrt[s_{NN}]=200 GeV. A strong azimuthal-angle dependence of the extracted Gaussian-source radii was observed with respect to both the second- and third-order event planes. The results for the second-order dependence indicate that the initial eccentricity is reduced during the medium evolution, which is consistent with previous results. In contrast, the results for the third-order dependence indicate that the initial triangular shape is significantly reduced and potentially reversed by the end of the medium evolution, and that the third-order oscillations are largely dominated by the dynamical effects from triangular flow.

Abstract
The search for the violation of the fundamental symmetry in a radioactive atom is the promising candidate for precision tests of the standard model and its possible extensions. The subtle signal arising from the symmetry violation is enhanced in heavy atoms, such as a francium (Fr). To realize high precision measurements, a large amount of radioactive isotopes is required. The Fr is produced via a nuclear fusion reaction using a melted gold target with a (18)O primary beam at Cyclotron and Radioisotope Center, Tohoku University. The maximum extraction efficiency of the Fr ion was achieved at approximately 35%. The beam line consists of an electrostatic deflector, three electrostatic quadrupole triplets to the measurement area at 10 m away from the reaction point, and several beam diagnosis systems. We optimized parameters of the beam line.

Abstract
UNLABELLED A 3-year follow-up study on 334 young Japanese females enrolled in a university at the age of 18 years revealed that discontinuation of leisure time impact-loading exercises performed in junior high and/or high school was associated with increased risk of reduction in calcaneus osteo-sono assessment index (OSI). INTRODUCTION Bone strength rapidly increases during puberty and reaches its peak by the end of adolescence. The aim of this study was to determine the lifestyle factors that influence the maintenance of calcaneus OSI in young adult females around the time when peak bone mass is attained. METHODS Annual health checkups including OSI measurements, anthropometrics, lifestyle analysis, and blood examination were performed 4 times on 334 Japanese females enrolled in a university at the age of 18 years. According to the slope of OSI change during the 3-year follow-up, the subjects were grouped into two categories: OSI loss (the lowest tertile) and OSI gain/stable (the second and third tertiles). RESULTS At the baseline assessment, the OSI loss group had higher OSI and height and an earlier menarche age than the OSI gain/stable group. Performing leisure time impact-loading exercise in junior high and/or high school but discontinuing it at university was associated with increased risk of OSI loss, independent of OSI, height and weight at the age of 18 years, weight change during follow-up, age of menarche, energy-adjusted nutrient intake, and alcohol drinking; the odds ratios were 4.1-4.9 compared with those performing impact-loading exercise at university. In particular, duration, frequency, and subjective intensity of impact-loading exercise during high school were positively associated with OSI loss. CONCLUSION Discontinuation of leisure time impact-loading exercises performed during late adolescence is associated with an increased risk of OSI loss in young adult females during the 3-year follow-up period.

Abstract
Mechanical vibration enhances the cytoplyasmic maturation of in vitro-matured (IVM) pig oocytes (Mizobe et al. 2010 J. Reprod. Dev. 56, 285–290), as well as the development of in vitro-cultured (IVC) bovine embryos (Fujita et al. 2010 Rakuno Gakuen University Graduation thesis,1–36). In this study, the effects of intervals of mechanical vibration during in vitro culture, after IVF, on the development of embryos derived from low-quality oocytes were examined. Cumulus-oocyte complexes (COC) were collected by aspiration of ovarian follicles (diameter = 2 to 6 mm) obtained from a local abattoir. In this experiment, only grade 3 oocytes (i.e. those with one layer or partially remaining cumulus cells and normal cytoplasm) were used. Groups of 20 COC were matured in 100-μL droplets of in vitro TCM-199 supplemented with 5% calf serum and 0.02 AU mL–1 of FSH at 38.5°C under an atmosphere of 5% CO2 in air for 20 h. Matured COC were inseminated with 5 × 106 sperms mL–1 for 18 h. After 18 h of gamete co-culture, the presumptive zygotes were cultured in CR1aa medium supplemented with 5% calf serum at 38.5°C under an atmosphere of 5% O2, 5% CO2, and 90% N2 for 9 days (fertilization = Day 0). Presumptive zygotes were cultured in vitro without mechanical vibration (control; n = 467) and with mechanical vibration for 5 s at 5 min (n = 180), 10 min (n = 180), 15 min (n = 180), and 60 min (n = 200) for 9 days. Embryo development was evaluated for cleavage and blastocyst rates, on Days 3 and 7 to 9 after IVF, respectively. The cleavage and blastocyst formation rates were analysed by the chi-squared test. Vibration at 15-min intervals increased (P < 0.05) cleavage rate compared to 5 min, 60 min, and control (control: 66.2 ± 22.1%; 5 min: 49.4 ± 10.2%; 10 min: 70.0 ± 7.7%; 15 min: 86.2 ± 6.6%; and 60 min: 64.0 ± 8.5%).The highest (P < 0.05) blastocyst rate among the experimental groups was found with 15-min intervals for vibration (control: 21.6 ± 9.2%; 5 min: 15.0 ± 5.3%; 10 min: 22.8 ± 1.8%; 60 min: 21.5 ± 5.0%). These results indicated that the cleavage and blastocyst formation rates of IVM-IVF-IVC bovine embryos derived from low-quality oocytes can be improved by physical stimulus during IVC. In addition, it was shown that 15-min intervals of mechanical vibration elicited the highest benefit for the development of embryos.

Abstract
Previously, it was reported that a high rate of good quality blastocysts were produced by IVF of in vivo-matured oocytes, obtained by ovum pick up (OPU) after superstimulation in Holstein cows, using X-sorted sperm (Matoba et al. 2012 Reprod. Domest. Anim. 47, 515). In this system, an early first cleavage within 28 h after IVF was found to be a potent marker for the selection of embryos with high developmental competence (Matoba et al. 2013 Reprod. Fertil. Dev. 25, 266). However, we have limited knowledge on the timing and normality of embryonic cleavages in in vitro-matured oocytes after IVF. The purpose of the present study was to compare the kinetics and patterns of the first cleavage of in vivo- and in vitro-matured bovine oocytes after IVF with X-sorted sperm. In vivo-matured oocytes (Group A) were collected by OPU from non-lactating Holstein cows just before ovulation after superstimulation. Immature oocytes were either collected by OPU without hormonal treatment or by aspiration of ovaries at the local abattoir and matured in vitro (Group B or C). All the oocytes were inseminated with 5 × 106 sperm mL–1 of X-sorted sperm, except half of oocytes in Group C inseminated by non-sorted sperm (Group D) and cultured in CR1aa supplemented with 5% calf serum and 0.25 mg mL–1 of linoleic acid albumin at 38.5°C in 5% CO2, 5% O2, and 90% N2 for 216 h. Embryo kinetics were observed individually using a microwell culture dish and time-lapse cinematography (Sugimura et al. 2010 Biol. Reprod. 83, 970–978). Photographs of each embryo were taken in every 15 min during the IVC period and analysed by time-lapse cinematography software. Cleavage pattern was categorized as normal (2 even blastomeres without fragment or protrusion) or abnormal (2 uneven blastomeres, with fragment or protrusion and those dividing into 3–5 blastomeres) at the first cleavage. Data were analysed by ANOVA, chi-squared, or discriminant function. A total of 268 cleaved embryos were used. The blastocyst rate in Group A was higher than in Groups B and C (61.3 v. 40.0 and 25.0%, respectively; P < 0.05). The timing of first cleavage was longer in Group A compared with Groups C and D (28.3 ± 3.8 v. 27.6 ± 3.8 and 26.7 ± 1.9 h, respectively) and in Group B (28.1 ± 4.0 h) compared with in Group D (P < 0.05). Higher rates of normal cleavage were observed in Groups A, B, and D than in Group C (53.5, 44.4, and 54.8 v. 16.7%, respectively; P < 0.01). The frequency of blastocysts derived from the early (28.3 h) and normal pattern cleaving oocytes were greater in Groups A and B than in Group C (29.0 and 20.0 v. 8.3%, respectively; P < 0.05) and similar in Group D (22.6%). Our results reveal that IVF embryos produced from in vivo-matured oocytes with sex-sorted sperm had superior normality than those produced from in vitro-matured oocytes and similar normality to embryos inseminated with non-sorted sperm.

Abstract
In beef cattle, 20 to 44% embryonic loss occurs during the early stages of pregnancy (Humblot et al. 2001). However, the mechanism of early and late embryonic death is not clear. We investigated occurrence of embryonic death by monitoring ovarian hormones dynamics and checking for the presence of the conceptus after artificial insemination or embryo transfer in beef cattle. Twenty Japanese black females were inseminated (AI) and 12 females were transferred with 1 embryo (ET). Blood samples were collected on Days 21, 24, 28, 38, 48, 58, and 68 post-oestrus (oestrus = Day 0) and then stored at –30°C. Progesterone (P4) and oestradiol (E2) plasma concentrations were analysed using a chemiluminescent immunoassay. On each day of blood sampling, ovaries and presence of a conceptus in the uterus were monitored by ultrasonography. At Day 24 post-oestrus, the presence of the fetus was detected in 8 females (AI, n = 6; ET, n = 2), whereas only 3 females were confirmed to be pregnant at Day 28 and Day 38 post-oestrus. No embryo loss was seen at later stages of pregnancy (Days 48, 58, and 68 post-oestrus). At Day 21 post-oestrus, the conceptus could not be detected by ultrasonography but the E2/P4 ratio provided indication on the pregnancy status of the females that were classified as pregnant (n = 8) or not pregnant (n = 24) at day 24 post-oestrus (1.7 ± 2.2 versus 28.0 ± 34.2 respectively; mean ± s.d.). In the nonpregnant females compared with the pregnant ones at Day 24 post-oestrus, P4 declined below 1 ng mL–1 (0.6 ± 0.2 ng mL–1 v. 8.6 ± 3.9 ng mL–1), whereas E2 blood level remained stable (15.7 ± 21.9 v. 18.1 ± 1.1 pg mL–1). The decrease in P4 levels led to an increase in E2/P4 ratio (1.3 to 37.3 on Day 24). Our study suggests that a large proportion of embryo loss (75%) occurs before Day 24, whereas an additional 16% loss was seen between Day 24 and Day 28 post-oestrus. This embryo loss was shown to be associated with the altered balance of ovarian hormones.
