Abstract
AIM Laparoscopic ventral rectopexy (LVR) is considered an effective treatment for rectal prolapse and/or rectoanal intussusception. After the dissection of the rectovaginal septum down to the pelvic floor, a strip of mesh is introduced and should be secured as distally as possible. We have developed a novel technique of introducing the mesh at the distal dissection. METHOD A nylon thread with straight needle was passed through the posterior wall of vagina at the distal extent of the dissection, which was caught in the abdominal cavity and fixed at the end of the mesh extracorporeally. The mesh was then introduced, pulled toward the pelvic floor and settled at the pierced site by the perineal operator. RESULTS Sixty-eight female patients underwent LVR using this technique. There were no intra-operative and postoperative mesh-related complications. The mean distance from the vaginal ostium to the point of passing a nylon thread through the posterior wall of the vagina was 2 cm. Postoperative proctography showed the anatomical correction in 47 of the 48 patients who were examined. CONCLUSION The surgeon can confirm that the mesh is introduced and secured at the distal dissection by using this technique while performing LVR.

Abstract
AIM This study evaluated continence, constipation and quality of life (QOL) before and after laparoscopic ventral rectopexy (LVR) METHOD: Between February 2012 and July 2014, patients who underwent LVR for external rectal prolapse (ERP) and/or rectoanal intussusception (RAI) were prospectively included. A standard questionnaire including the Fecal Incontinence Severity Index (FISI), the Constipation Scoring System (CSS) and QOL instruments (Short-Form 36 Health Survey, Fecal Incontinence QOL scale, Patient Assessment of Constipation-QOL) were administered before and after operation. Psychiatric patients and those with dementia were excluded from the study. Defaecography was performed 6 months postoperatively. RESULTS Fifty-nine patients were included in the study period and 44 (19 with ERP, 25 with RAI) completed the follow-up questionnaire and were reviewed after a median of 26 (range 12-42) months. There was no recurrent ERP. Postoperative defaecography showed new-onset RAI in 6 and persistent RAI in 1. One year after surgery, incontinence was improved in 30/39 patients (77%) and constipation in 19/32 (59%). The FISI scores reduced between preoperative status and 1 year after surgery [32 (13-61) vs 11 (0-33), P < 0.0001]. The CSS scores also reduced [preoperative 12 (5-18) vs 1 year 5 (1-12), P < 0.0001]. Compared with the preoperative scores, almost all of the scale scores on the three kinds of QOL instruments significantly improved over time. The presence of new-onset or persistent RAI did not have an adverse effect on the improvement of QOL. CONCLUSION LVR improves both generic and symptom-specific QOL with good functional results.

Abstract
The ϕ-Λ(1520) interference effect in the γp→K^{+}K^{-}p reaction has been measured for the first time in the energy range from 1.673 to 2.173 GeV. The relative phases between ϕ and Λ(1520) production amplitudes were obtained in the kinematic region where the two resonances overlap. The measurement results support strong constructive interference when K^{+}K^{-} pairs are observed at forward angles but destructive interference for proton emission at forward angles. Furthermore, the observed interference effect does not account for the sqrt[s]=2.1 GeV bump structure in forward differential cross sections for ϕ photoproduction. This fact suggests possible exotic structures such as a hidden-strangeness pentaquark state, a new Pomeron exchange, or rescattering processes via other hyperon states.

Abstract
Intestinal immune homeostasis requires dynamic crosstalk between innate and adaptive immune cells. Dendritic cells (DCs) exist as multiple phenotypically and functionally distinct sub-populations within tissues, where they initiate immune responses and promote homeostasis. In the gut, there exists a minor DC subset defined as CD103(+)CD11b(-) that also expresses the chemokine receptor XCR1. In other tissues, XCR1(+) DCs cross-present antigen and contribute to immunity against viruses and cancer, however the roles of XCR1(+) DCs and XCR1 in the intestine are unknown. We showed that mice lacking XCR1(+) DCs are specifically deficient in intraepithelial and lamina propria (LP) T cell populations, with remaining T cells exhibiting an atypical phenotype and being prone to death, and are also more susceptible to chemically-induced colitis. Mice deficient in either XCR1 or its ligand, XCL1, similarly possess diminished intestinal T cell populations, and an accumulation of XCR1(+) DCs in the gut. Combined with transcriptome and surface marker expression analysis, these observations lead us to hypothesise that T cell-derived XCL1 facilitates intestinal XCR1(+) DC activation and migration, and that XCR1(+) DCs in turn provide support for T cell survival and function. Thus XCR1(+) DCs and the XCR1/XCL1 chemokine axis have previously-unappreciated roles in intestinal immune homeostasis.

Abstract
Abstract
Exon 2 of MED12, a subunit of the transcriptional mediator complex, has been frequently mutated in uterine leiomyomas and breast fibroadenomas; however, it has been rarely mutated in other tumors. Although the mutations were also found in uterine leiomyosarcomas, the frequency was significantly lower than in uterine leiomyomas.
Here, we examined the MED12 mutation in phyllodes tumors, another biphasic tumor with epithelial and stromal components related to breast fibroadenomas. Mutations in
MED12 exon 2 were analyzed in nine fibroadenomas and eleven phyllodes tumors via
Sanger sequencing. A panel of cancer- and sarcoma-related genes was also analyzed using Ion Torrent next-generation sequencing. Six mutations in fibroadenomas, including those previously reported (6/9, 67%), and five mutations in phyllodes tumors (5/11, 45%) were observed. Three mutations in the phyllodes tumors were missense mutations at
Gly44, which is common in uterine leiomyomas and breast fibroadenomas. In addition, two deletion mutations (in-frame c.133_144del12 and loss of splice acceptor
c.100-68_137del106) were observed in the phyllodes tumors. No other recurrent mutation was observed with next-generation sequencing. Frequent mutations in MED12 exon 2 in the phyllodes tumors suggest that it may share genetic etiology with uterine leiomyoma, a subgroup of uterine leiomyosarcomas and breast fibroadenoma.

Abstract
BACKGROUND Rectoanal intussusception (RAI) is a common finding on evacuation proctography in patients with defecation disorders. However, it remains unclear whether intussusception morphology affects the severity of fecal incontinence (FI). The aim of this study was to examine the effect of morphology during defecation on the severity of FI in patients with RAI. METHODS We included 80 patients with FI who were diagnosed as having RAI on evacuation proctography. Various morphological parameters were measured, and the level of RAI was divided by the extent of descent onto (level I) or into (level II) the anal sphincter. FI symptoms were documented using the FI Severity Index (FISI). RESULTS Twenty-eight patients had level I and 52 had level II RAI. The mean (range) FISI score was 24.0 (8-47). FISI scores tended to be significantly higher in level II than in level I [26.3 (10-47) vs. 21.8 (8-42); p = 0.05]. The mean anterior intussusception descent was significantly greater in level II than in level I [24.2 (9.2-39.5) vs. 17.7 (7.8-39.4) mm; p < 0.0001]. Regression analysis showed that anterior intussusception descent was predictive of increased FISI scores. CONCLUSIONS The severity of FI may be affected by anterior intussusception descent in patients with RAI.

Abstract
BACKGROUND This study was designed to assess defecatory function in patients who underwent laparoscopic ventral rectopexy (LVR) for external rectal prolapse (ERP). METHODS Thirty-one patients who underwent evacuation proctography 6 months postoperatively were assessed. Preoperative proctography had been performed in 21 patients of these patients. Defecatory function was evaluated using the constipation scoring system (CSS) and fecal incontinence severity index (FISI). RESULTS The findings of postoperative proctography revealed no full-thickness ERP in any patient, although in 10 patients the ERP was replaced by rectoanal intussusception (RAI). Of the 31 patients, 30 presented with fecal incontinence preoperatively. Ten of 30 had new-onset RAI. Six months postoperatively, a reduction of at least 50 % in the FISI score of the patients with new-onset RAI tended to be significantly smaller than in the patients without RAI (6/10 vs. 18/20, p = 0.141). Seventeen patients presented with obstructed defecation preoperatively. Seven of them had new-onset RAI. Six months postoperatively, a reduction of at least 50 % in their CSS score in the patients with new-onset RAI was significantly smaller than in patients without RAI (0/7 vs. 8/10, p = 0.002). CONCLUSIONS Evacuation proctography showed new-onset RAI in some patients with ERP who underwent LVR, which was associated with a lack of symptomatic improvement.

Abstract
Background The exact sequence of events leading to ultimate hepatocellular damage following ischemia/reperfusion (I/R) is incompletely understood. In this article, we review a mechanism of organ dysfunction after hepatic I/R or immunosuppressive treatment, in addition to the potential of liver sinusoidal endothelial cell (LSEC) protection and antiplatelet treatment for the suppression of hepatocellular damage. Methods A review of the literature, utilizing PubMed-NCBI, was used to provide information on the components necessary for the development of hepatocellular damage following I/R. Results It is well-established that LSECs damage following hepatic I/R or immunosuppressive treatment followed by extravasated platelet aggregation (EPA) is the root cause of organ dysfunction in liver transplantation. We have classified three phases, from LSECs damage to organ dysfunction, utilizing the predicted pathogenic mechanism of sinusoidal obstruction syndrome. The first phase is detachment of LSECs and sinusoidal wall destruction after LSECs injury by hepatic I/R or immunosuppressive treatment. The second phase is EPA, accomplished by sinusoidal wall destruction. The various growth factors, including thromboxane A2, serotonin, transforming growth factor-beta and plasminogen activator inhibitor-1, released by EPA in the Disse’s space of zone three, induce portal hypertension and the progression of hepatic fibrosis. The third phase is organ dysfunction following portal hypertension, hepatic fibrosis, and suppressed liver regeneration through various growth factors secreted by EPA. Conclusion We suggest that EPA in the space of Disse, initiated by LSECs damage due to hepatic I/R or immunosuppressive treatment, and activated platelets may primarily contribute to liver damage in liver transplantation. Endothelial protective therapy or antiplatelet treatment may be useful in the treatment of hepatic I/R following EPA.

Abstract
BACKGROUND Recent advances in gastric cancer chemotherapy have made macroscopic complete resection possible in some patients with stage IV disease. METHODS We retrospectively investigated the efficacy of multimodal therapy with combined docetaxel, cisplatin, and S-1 (DCS) and conversion gastrectomy in 57 patients with stage IV gastric cancer. RESULTS Of the 57 patients, 15 patients were categorized into potentially resectable case, which is defined as patients with single incurable factor including the upper abdominal para-aortic lymph node metastasis (16a2b1 PAN metastasis) or fewer than three peripheral liver metastases. The other 42 were categorized as initially unresectable. All of patients underwent DCS therapy, and then 34 patients underwent conversion gastrectomy. The 3-year overall survival (OS) rate among the patients who underwent conversion gastrectomy was 50.1% with MST of 29.9 months. They had significantly longer OS than patients who underwent DCS therapy alone (p < 0.01). Univariate analysis among the patents with conversion gastrectomy identified 16a2b1PAN metastasis, peritoneal metastasis, potential resectable case, R0 resection as significant prognostic factors. A 3-year OS in potential resectable cases was 92.9%. Multivariate analysis identified potential resectability as the only independent prognostic factor contributing to OS (HR 0.133, 95%CI 0.024-0. 744, p = 0.021). In contrast, clinical response was selected as the only independent prognostic factor in the subgroup of initially unresectable cases (HR 0.354, 95%CI 0.151-0.783, p = 0.021). CONCLUSION Patients with potentially resectable disease had a remarkably good prognosis among stage IV gastric cancer patients, and might be ideal candidates for conversion gastrectomy following DCS therapy.

Abstract
Growth performance, as well as marbling, is the main breeding objective in Japanese Black (JB) cattle, the major beef breed in Japan. The septin 7 (CDC10) gene, involved in cellular proliferation, is located within a genomic region of a quantitative trait locus for growth-related traits. In this study, we first showed that the expression levels of the CDC10 gene in the skeletal muscle were higher in JB steers with extremely high growth performance than in JB steers with extremely low growth, using real-time PCR. Further, a single nucleotide polymorphism (SNP), NC_007302.5:g.63264949G>C, was detected in the promoter region of the CDC10 gene and genotyped in three Japanese cattle breeds (known as 'Wagyu' in Japan) and the Brown Swiss dairy cattle breed. All four cattle populations showed a moderate genetic diversity at the SNP of the CDC10 gene. An association analysis indicated that the SNP was associated with growth-related traits in JB cattle. These findings suggest possible effects of the expression levels in the skeletal muscle and the SNP of the CDC10 gene on growth-related traits in JB cattle. The CDC10 SNP may be useful for effective marker-assisted selection to increase beef productivity in JB beef cattle.

Abstract
BACKGROUND AND PURPOSE Despite major progress in treating aneurysms by coil embolization, the complete occlusion of aneurysms of >10 mm in diameter (large/giant aneurysms) remains challenging. We present a novel endovascular treatment method for large and giant cerebral aneurysms called the "maze-making and solving" technique and compare the short-term follow-up results of this technique with those of conventional coil embolization. MATERIALS AND METHODS Eight patients (65 ± 11.5 years of age, 7 women) with large/giant unruptured nonthrombosed cerebral aneurysm (mean largest aneurysm dimension, 19 ± 4.4 mm) were treated by the maze-making and solving technique, a combination of the double-catheter technique and various assisted techniques. The coil-packing attenuation, postoperative courses, and recurrence rate of this maze group were compared with 30 previous cases (conventional group, 65.4 ± 13.0 years of age; 22 women; mean largest aneurysm dimension, 13.4 ± 3.8 mm). RESULTS Four maze group cases were Raymond class 1; and 4 were class 2 as indicated by immediate postsurgical angiography. No perioperative deaths or major strokes occurred. Mean packing attenuation of the maze group was significantly higher than that of the conventional group (37.4 ± 5.9% versus 26.2 ± 5.6%). Follow-up angiography performed at 11.3 ± 5.4 months revealed no recurrence in the maze group compared with 39.2% in the conventional group. CONCLUSIONS The maze-making and solving technique achieves high coil-packing attenuation for efficient embolization of large and giant cerebral aneurysms with a low risk of recurrence.

Abstract
BACKGROUND AND PURPOSE The risk factors of early hemorrhagic complications after endovascular coiling are not well-known. We identified the factors affecting early hemorrhagic complications, defined as any expansion or appearance of hemorrhage shown by head CT in the initial 48 hours after coiling. MATERIALS AND METHODS We retrospectively reviewed a series of 93 patients who underwent coiling for a ruptured saccular aneurysm between 2006 and 2012 at our hospital. RESULTS Five patients showed early hemorrhagic complications, and all involved an expansion of the existing intracerebral hematoma immediately after coiling. The associated risk factors were accompanying intracerebral hemorrhage at onset (P < .001), postoperative antiplatelet therapy (P < .001), and thromboembolic complications (P = .044). In the accompanying intracerebral hemorrhage group, the associated risk factors were postoperative antiplatelet therapy (P = .044) and earlier initiation of coiling (9.8 ± 6.5 versus 28.1 ± 24.0 hours, P = .023). Early hemorrhagic complications were significant risk factors for worse clinical outcome (modified Rankin Scale, 2.02 ± 2.21 versus 4.4 ± 2.30, P = .022). None of the 93 patients showed further hemorrhage after the initial 48 hours after coiling. CONCLUSIONS The accompanying intracerebral hemorrhage at onset, thromboembolic complications, postoperative antiplatelet therapy, and earlier initiation of coiling were the risk factors for early hemorrhagic complications.
