Abstract
STUDY QUESTION Do monosomy rescue (MR) and trisomy rescue (TR) in preimplantation human embryos affect other developmental processes, such as X-chromosome inactivation (XCI)? SUMMARY ANSWER Aneuploid rescue precedes XCI and increases the incidence of XCI skewness by reducing the size of the embryonic progenitor cell pools. WHAT IS KNOWN ALREADY More than half of preimplantation human embryos harbor aneuploid cells, some of which can be spontaneously corrected through MR or TR. XCI in females is an indispensable process, which is predicted to start at the early-blastocyst phase. STUDY DESIGN, SIZE, DURATION We examined the frequency of XCI skewness in young females who carried full uniparental disomy (UPD) resulting from MR or TR/gamete complementation (GC). The results were statistically analyzed using a theoretical model in which XCI involves various numbers of embryonic progenitor cells. PARTICIPANTS/MATERIALS, SETTING, METHODS We studied 39 children and young adults ascertained by imprinting disorders. XCI ratios were determined by DNA methylation analysis of a polymorphic locus in the androgen receptor gene. We used Bayesian approach to assess the probability of the occurrence of extreme XCI skewness in the MR and TR/GC groups using a theoretical model of 1-12 cell pools. MAIN RESULTS AND THE ROLE OF CHANCE A total of 12 of 39 individuals (31%) showed skewed XCI. Extreme skewness was observed in 3 of 15 MR cases (20%) and 1 of 24 TR/GC cases (4.2%). Statistical analysis indicated that XCI in the MR group was likely to have occurred when the blastocyst contained three or four euploid embryonic progenitor cells. The estimated size of the embryonic progenitor cell pools was approximately one-third or one-fourth of the predicted size of normal embryos. The TR/GC group likely had a larger pool size at the onset of XCI, although the results remained inconclusive. LIMITATIONS, REASONS FOR CAUTION This is an observational study and needs to be validated by experimental analyses. WIDER IMPLICATIONS OF THE FINDINGS This study provides evidence that the onset of XCI is determined by an intrinsic clock, irrespectively of the number of embryonic progenitor cells. Our findings can also be applied to individuals without UPD or imprinting disorders. This study provides a clue to understand chromosomal and cellular dynamics in the first few days of human development, their effects on XCI skewing and the possible implications for the expression of X-linked diseases in females. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by the Grants-in-aid for Scientific Research on Innovative Areas (17H06428) and for Scientific Research (B) (17H03616) from Japan Society for the Promotion of Science (JSPS), and grants from Japan Agency for Medical Research and Development (AMED) (18ek0109266h0002 and 18ek0109278h0002), National Center for Child Health and Development and Takeda Science Foundation.

Abstract
OBJECTIVE To examine characteristics and survival outcomes of women with surgically-treated cervical cancer exhibiting uterine corpus tumor invasion. METHODS We utilized The Surveillance, Epidemiology, and End Results Program to identify cervical cancer patients who underwent hysterectomy between 1973 and 2003. Logistic regression models were used to identify risk factors for uterine corpus tumor invasion on multivariable analysis. Association of uterine corpus tumor invasion and cause-specific survival (CSS) from cervical cancer was examined with Cox proportional hazard regression models on multivariable analysis. RESULTS We identified 837 (4.9%) cases of uterine corpus invasion and 16,237 (95.1%) cases of non-invasion. Median follow-up time was 14.0 years. There were 1642 deaths due to cervical cancer. Uterine corpus invasion was independently associated with older age, non-squamous histology, high-grade tumors, large tumor size, and nodal metastasis on multivariable analysis (all, P < 0.001). On univariable analysis, uterine corpus tumor invasion was significantly associated with decreased CSS compared to the non-invasion (5-year rates, 79.0% versus 94.5%, P < 0.001). After controlling for other significant prognostic factors, uterine corpus tumor invasion remained an independent prognostic factor for decreased CSS (adjusted-hazard ratio 1.45, 95% confidence interval 1.21-1.74). Among stage T1b cases (n = 6730), uterine corpus tumor invasion remained an independent prognostic factor for decreased CSS (adjusted-hazard ratio 1.95, 95%CI 1.47-2.60). Uterine corpus tumor invasion was significantly associated with decreased CSS in stage T1b1 disease (74.5% versus 90.7%, P < 0.001) and in stage T1b2 disease (67.0% versus 79.5%, P = 0.01). CONCLUSION Uterine corpus tumor invasion is an independent prognostic factor for decreased survival of women with early-stage cervical cancer.

Abstract
BACKGROUND To examine the effect of the histology of carcinoma and sarcoma components on survival outcome of uterine carcinosarcoma. PATIENTS AND METHODS A multicenter retrospective study was conducted to examine uterine carcinosarcoma cases that underwent primary surgical staging. Archived slides were examined and histologic patterns were grouped based on carcinoma (low-grade versus high-grade) and sarcoma (homologous versus heterologous) components, correlating to clinico-pathological demographics and outcomes. RESULTS Among 1192 cases identified, 906 cases were evaluated for histologic patterns (carcinoma/sarcoma) with high-grade/homologous (40.8%) being the most common type followed by high-grade/heterologous (30.9%), low-grade/homologous (18.0%), and low-grade/heterologous (10.3%). On multivariate analysis, high-grade/heterologous (5-year rate, 34.0%, P = 0.024) and high-grade/homologous (45.8%, P = 0.017) but not low-grade/heterologous (50.6%, P = 0.089) were independently associated with decreased progression-free survival (PFS) compared with low-grade/homologous (60.3%). In addition, older age, residual disease at surgery, large tumor, sarcoma dominance, deep myometrial invasion, lymphovascular space invasion, and advanced-stage disease were independently associated with decreased PFS (all, P < 0.01). Both postoperative chemotherapy (5-year rates, 48.6% versus 39.0%, P < 0.001) and radiotherapy (50.1% versus 44.1%, P = 0.007) were significantly associated with improved PFS in univariate analysis. However, on multivariate analysis, only postoperative chemotherapy remained an independent predictor for improved PFS [hazard ratio (HR) 0.34, 95% confidence interval (CI) 0.27-0.43, P < 0.001]. On univariate analysis, significant treatment benefits for PFS were seen with ifosfamide for low-grade carcinoma (82.0% versus 49.8%, P = 0.001), platinum for high-grade carcinoma (46.9% versus 32.4%, P = 0.034) and homologous sarcoma (53.1% versus 38.2%, P = 0.017), and anthracycline for heterologous sarcoma (66.2% versus 39.3%, P = 0.005). Conversely, platinum, taxane, and anthracycline for low-grade carcinoma, and anthracycline for homologous sarcoma had no effect on PFS compared with non-chemotherapy group (all, P > 0.05). On multivariate analysis, ifosfamide for low-grade/homologous (HR 0.21, 95% CI 0.07-0.63, P = 0.005), platinum for high-grade/homologous (HR 0.36, 95% CI 0.22-0.60, P < 0.001), and anthracycline for high-grade/heterologous (HR 0.30, 95% CI 0.14-0.62, P = 0.001) remained independent predictors for improved PFS. Analyses of 1096 metastatic sites showed that carcinoma components tended to spread lymphatically, while sarcoma components tended to spread loco-regionally (P < 0.001). CONCLUSION Characterization of histologic pattern provides valuable information in the management of uterine carcinosarcoma.

Abstract
The Gyro centrifugal pump developed as a totally implantable artificial heart was designed with a free impeller, in which the rotational shaft (male bearing) of the impeller was completely separated from the female bearing. For this type of pump, it is very important to keep the proper magnet balance (impeller-magnet and actuator-magnet) in order to prevent thrombus formation and/or bearing wear. When the magnet balance is not proper, the impeller is jerked down into the bottom bearing. On the other hand, if magnet balance is proper, the impeller lifted off the bottom of the pump housing within a certain range of pumping conditions. In this study, this floating phenomenon was investigated in detail. The floating phenomenon was proved by observation of the impeller behavior using a transparent acrylic pump. The impeller floating phenomenon was mapped on a pump performance curve. The impeller floating phenomenon is affected by the magnet-magnet coupling distance and rotational speed of the impeller. In order to keep the proper magnet balance and to maintain the impeller floating phenomenon at the driving condition of right and left pump, the magnet-magnet coupling distance was altered by a spacer which was installed between the pump and actuator. It became clear that the same pump could handle different conditions (right and left ventricular assist), by just changing the thickness of the spacer. When magnet balance is proper, the floating impeller phenomenon occurs automatically in response to the impeller rev. It is called "the dynamic RPM suspension".

Abstract
The degradation of rabbit, chicken and beef myofibrils by cathepsin L or lysosomal lysates was studied by SDS-polyacrylamide-gel electrophoresis and electron microscopy (EM). Similar degradation patterns were observed for each myofibrillar preparation incubated with cathepsin L, except that myosin heavy chain and tropomyosin of beef were more susceptible than those of rabbit and chicken. Otherwise, troponin T, troponin in I and C-protein were rapidly degraded with slower degradation of titin, nebulin, myosin heavy chain, α-actinin, α-tropomyosin, actin and myosin light chains, LC1 and LC2. However, the component of 30 000 Mr was found to be further degraded to smaller peptides. Degradation at pH 5·5 (approximate post-mortem limit value) was faster than at pH 6·0 but slower than at pH 5·0. A number of new protein bands were identified (130 000, 120 000, 90 000, 85 000, 80 000, 31 000 and 30 000 Mr). The degradation patterns of rabbit myofibrils by rabbit muscle lysosomal lysates were similar to that of myofibrils incubated with purified cathepsin L except for the retention of the 30 000 Mr component and reduced degradation of actin, due presumably to the reduced amount or stability of cathepsin L in the crude enzyme preparations. Electron micrographs revealed that myofibrillar degradation by cathepsin L occurred preferentially at the Z-lines leading to removal of the Z-line proteins and fracturing of the myofibrils at these sites. Catheptic damage was seen to be most rapid in chicken myofibrils and least rapid in beef myofibrils consistent with the more rapid conditioning process in chicken.

Abstract
We describe a new way to raise the V-Y advancement flap, which is useful for reconstruction of the lower lip. Various other methods have been reported in the past, but it has been necessary to choose the most suitable method for each particular case. A V-Y advancement flap from the submandibular region is one of the useful techniques to reconstruct the lower lip, and it is suitable for a wide horizontal defect. However, the conventional V-Y flap is insufficiently mobile and the reconstructed vermilion is thin because of the limitation of the pedicle. In such a case, the reconstructed lip may sag or cause an embarrassing defect. We developed a new way to raise the flap to obviate these problems. We use the V-Y advancement flap from the inferior margin of the defect in a conventional way after excision of the tumour, and use a mucosal flap to reconstruct the vermilion border. The skin side of the V-Y flap is undermined, and the orbicularis oris muscles are preserved on both sides as pedicles. The flap is then raised as a bipedicled musculocutaneous flap, which has adequate movement. After the flap has been sutured, the superior margin of the flap is de-epithelialised, and used to create the volume of the vermilion border. Functionally and cosmetically good results were achieved.

Abstract
BACKGROUND Purpura fulminans (PF) is a rare syndrome of intravascular thrombosis and haemorrhagic infarction of the skin. The initial symptom of PF is peripheral purpura which progresses to necrosis very rapidly. The prognosis of PF is poor, and the mortality is reported to be around 40%. Even if the patient survives, the patient may require amputation or reconstruction for limbs and facial necrosis. CASE REPORT A 48-year-old male suffered from PF following a left cerebellopontine angle tumour excision. His nose and upper lip fell into necrosis afterwards. We performed nose and upper lip reconstruction at 8 months after the onset. We used a forehead flap for the nasal reconstruction and a free forearm flap for the lining. His upper lip was reconstructed with bilateral nasolabial orbicularis oris myocutaneous flaps. RESULTS The colour and texture match of the reconstructed nose and lip is good. He could open his mouth wide enough and close completely. CONCLUSIONS Facial reconstruction after PF is very difficult, because the patient has extensive scarring around the defect and there is little intact facial tissue. However, we performed a facial reconstruction using local flaps as much as possible, and obtained good results.

Abstract
We have evaluated the relationship between exhaled carbon monoxide (CO) level and neutrophil-related functions such as reactive oxygen species (ROS) production capability, phagocytic activity and serum opsonic activity in the general population. Serum opsonic activity was determined by measuring the effects of serum on neutrophil ROS production capability using lucigenin- and luminol-dependent chemiluminescence (LgCL, LmCL). LgCL is associated with the detection of O(2)(-) , whereas LmCL mainly detects H(2)O(2) and HOCl, which are higher reactive oxygen radicals. In females, exhaled CO level was found to have positive associations with ROS production capability and LgCL. However, the opposite tendency was seen between exhaled CO level and LmCL in both genders. This result suggests that neutrophil ROS production in females may have contributed to oxidative stress, which led to the increases in intrinsic CO and exhaled CO consequently. Such changes then may have inhibited the process of changing reactive oxygen radicals into higher oxidizing potential levels.

Abstract
A high-throughput screening technique has been developed and was utilized in the discovery of a new n-type oxide possessing good thermoelectric properties. Screening of metal binary systems consisting of 3d transition metals using this technique showed LaNiO3 to possess the desired n-type properties. Electrical resistivity (ρ) of this oxide is favorably quite low, however, the Seebeck coefficient (S) is as small as –25 μV/K. To enhance the thermoelectric properties of LaNiO3, high-throughput screening was employed to examine candidates from the metal ternary La1–xMxNiO3 and LaNi1–xNxO3 systems. Bi substitution in the La1–xMxNiO3 systems and Cu substitution in the LaNi1–xNxO3 systems were found to be effective for improvement of S and ρ respectively.

Abstract
Deformity or loss of the ear may be caused by superficial dermal burns or deep burns. The depth of ear burns is progressive because the ear protrudes from head and is easily affected by external pressure. Therefore, burn wounds of the ear should be debrided as early as possible, before irreversible changes of the cartilage, and covered with healthy tissue. We describe a surgical procedure for treatment of the extensively burned ear. With this technique, the helix is covered by a postauricular advancement flap, and the antihelix is covered by a skin graft. Because the procedure is straightforward and can be completed within a short time, it can be performed at the same time as other life-saving measures. The use of a skin flap permits adequate debridement in terms of both depth and width, minimising the risk of infection. The helix can be reconstructed to provide a natural appearance, and late ulcer formation due to external irritation is prevented. We have treated 15 ears on 11 patients with this procedure and have consistently obtained a satisfactory outcome.

Abstract
We report on the structural, microstructural, and electronic properties of iodine intercalated [Bi0.82CaO2]2[CoO2]1.69 misfit cobaltite. We first prove through a detailed and careful structural study that the block layer structure can be modified in the desired way. Iodine enters the material between the [BiO] double layers, and the c-cell parameter of the pristine compound is elongated by 3.6 Angstrom. On the basis of this result, we point out the coupling between the block-layer structure and the transport properties. Additionally, we provide in-depth commentary and discussion of some extra results, clarifying some doping effects in the quasi-2D studied phase. Finally, we also propose some expressions that might be useful to material scientists for the tuning of the properties of such compounds.

Abstract
We performed a clinical analysis on 8 patients with primary follicular lymphoma in the duodenum taken from among 26 cases of primary gastrointestinal malignant lymphoma treated in our division. The median age was 60 years (range 48 to 82 yr). The ratio of males to females was 4:4. The chief complaints were no symptoms in 4 cases, heartburn in 2 cases, lower abdominal pain in 1 case, and back pain in 1 case. All patients were in clinical stage I EA. Gastroendoscopic findings showed multiple whitish granules around the ampulla of Vater in all patients. Involvement of the site in 6 cases was only located at the second portion; lesions in the other 2 cases were located at the second portion, and at the third portion or fourth portion, respectively. A histological study showed follicular lymphoma grade 1, and an immunohistological study demonstrated that the lymphoma cells were positive for CD79a, CD10, CD20, and bcl-2. Five patients were positive for the FISH analysis fusion signal of IgH/bcl-2 genes. Rituximab with CHOP therapy was performed for 7 patients. Seven patients are currently alive, and one died of uterine cancer. At the medium-term 39 month-follow-up, 7 patients were in complete remission, and 1 patient was in partial remission. Rituximab with CHOP (CVP) therapy is a possible treatment for primary follicular lymphoma in the duodenum. Further consideration of appropriate therapy for this disease might be necessary.
