Abstract
Mesenchymal stem/stromal cell (MSC) therapy has been investigated in multiple diseases and conditions. Although the mechanisms of MSC-based therapies are not fully understood, we and others have shown interleukin 6 (IL-6) to be an important factor in MSC function. IL-6 contributes to many biological events, such as immune response, neurogenesis, and bone remodeling. In our study, we tested the feasibility of engineering MSCs by IL-6 mRNA transfection (eMSCs-IL6) and evaluated the optimal time to harvest them after transfection. We then assessed the functional characteristics of eMSCs-IL6. Quantitative real-time PCR and ELISA results have shown that mature IL-6 mRNA was efficiently transfected into MSCs using a lipofectamine based method. The IL-6 mRNA and protein overexpression peaked after 1 day of transfection and the secreted IL-6 protein was sustained for at least 6 days. A short time course experiment demonstrated that 4 h after transfection was the best time point to harvest and freeze eMSCs-IL6 for future studies. In addition, eMSCs-IL6 maintained their characteristics as defined by International Society for Cell & Gene Therapy. The immunosuppressive capacity of conditioned culture medium (CCM) from eMSCs-IL6 (CCM-IL6) was significantly enhanced compared to naïve MSCs conditioned culture medium (CCM-control). Our studies established for the first time the feasibility of efficiently generating IL-6 overexpressing MSCs which have enhanced immunosuppressive capacity. This is providing a novel approach to improve the efficacy of MSCs for potential application in regenerative medicine.

Abstract
Mesenchymal stem cells (MSCs) are used in various studies to induce immunomodulatory effects in clinical conditions associated with immune dysregulation such as graft versus host disease (GvHD). However, most of these clinical trials failed to go beyond early phase 2 studies because of limited efficacy. Various methods have been assessed to increase the potency of MSCs. IL-10 is an anti-inflammatory cytokine that is known to modulate immune responses in GvHD. In this study, we evaluated the feasibility of transfecting IL-10 mRNA to enhance MSC therapeutic potential. IL-10 mRNA engineered MSCs (eMSCs-IL10) maintained high levels of IL-10 expression even after freezing and thawing. IL-10 mRNA transfection did not appear to alter MSC intrinsic characteristics. eMSCs-IL10 significantly suppressed T cell proliferation relative to naïve MSCs in vitro. In a mouse model for GvHD, eMSCs-IL10 induced a decrease in plasma level of potent pro-inflammatory cytokines and inhibited CD4+ and CD8+ T cell proliferation in the spleen. In summary, our studies demonstrate the feasibility of potentiating MSCs to enhance their immunomodulatory effects by IL-10 mRNA transfection. The use of non-viral transfection may generate a safe and potent MSC product for treatment of clinical conditions associated with immune dysregulation such as GvHD.

Abstract
The naughty genes and 3D structure of the endometrium

The human endometrium is a highly regenerative tissue and involved in menstruation and implantation of the fertilized egg, giving it a central role in women’s reproductive health. However, the regenerative nature of the endometrial glands can lead to the development and progression of “endometrium-related diseases” such as adenomyosis, endometriosis, endometriosis-associated ovarian cancer, endometrial hyperplasia, and endometrial cancer. To clarify the pathogenesis of endometrium-related diseases and develop effective preventative measures and therapeutic strategies, comprehensive understanding of molecular biological linkage between endometrium and endometrium-related diseases was crucially important.
To this end, we focused on genomic alterations of endometrial epithelium which is considered the origin of endometriosis, and sequenced 107 ovarian endometriotic and 82 normal uterine endometrial epithelium samples isolated by laser-microdissection. Intriguingly, several genes recurrently mutated in endometriosis-associated ovarian cancers were frequently mutated in both endometriotic epithelium and normal uterine endometrial glands. In particular, PIK3CA mutation was detected in 41% of endometrial epithelium subjects but none of them had shared PIK3CA mutations across multiple regions collected from the same individuals. Mutation allele frequencies of somatic mutations in uterine endometrial epithelium samples were also significantly lower than those in ovarian endometriotic epithelium samples, suggesting the heterogeneous genomic compositions in uterine endometrium. To interpret this genomic heterogeneity in uterine endometrium, we focused on endometrial gland, the minimum functional unit of uterine endometrium, and conducted 109 single endometrial glands sequencing. As a result, we unveiled that each gland carried distinct somatic mutations in cancer-associated genes, such as PIK3CA, KRAS, and PTEN, with high mutant allele frequencies, suggesting the monoclonality of each gland. The presence of cancer-associated gene mutations in histologically normal endometrial glands provides important clues regarding the pathogenesis of endometrium-related diseases.
However, our previous study could not determine the spread of endometrial gland harboring cancer-associated gene mutation because there is a limitation to two-dimensional assessment of the whole shapes of endometrial gland due to its complicatedly winding morphology. Therefore, we tackled with three-dimensional (3D) assessment of human endometrium. To construct a large picture of endometrial gland structure, we performed tissue-clearing-based 3D imaging of full-thickness human uterine endometrial tissue with the use of light-sheet fluorescence microscopy. Our 3D immunohistochemistry discovered some new and unique 3D morphologies of endometrial glands, including plexus network of glands or occluded glands. Notably, computational analysis of 3D layer clarified that the plexus structure of the glands was mainly located in the stratum basalis and expanded along muscular layer horizontally, similar to the so-called “rhizome of grass”. Although previous studies have shown the 3D structure of murine endometrial glands, the bottom of these glands forms a crypt but not a rhizome. This can potentially be explained by the existence of menstruation, which is the crucial difference between the human and murine endometrium. The rhizome structure of endometrial gland in the human endometrium will have a functional advantage over the crypt in terms of the conservation of progenitor/stem cells and regeneration. In addition, some endometrial glands shared the plexus and rose toward the luminal epithelium, suggesting that these glands were the same origin. The rhizome of the endometrium may be a crucial element for understanding the expansion of endometrial glands harboring cancer-associated gene mutations.
Integrated analysis of the naughty gene alterations and the 3D structure in human endometrium will lead to a better understanding of the human endometrium in various fields, including histology, pathology, pathophysiology, reproduction, and oncology.

Abstract
Recurrent laryngeal nerve paralysis (RLNP) is a frequent and serious complication following esophageal cancer surgery. Therefore, this study aims to evaluate the correlation between recurrent laryngeal nerve (RLN) size and RLNP. This was a retrospective study of esophageal cancer patients who underwent thoracoscopic esophagectomy from January 2012 to December 2014. Eighty-four patients were included in the primary analysis. Diameter of the RLN was measured using the digital video recording of surgical procedures by the ratio between scissor and RLN. For evaluation of vocal cord paralysis or paresis, indirect laryngoscopy was performed. Because RLNP more frequently occurs on the left side than the right, we evaluated the correlation between size of the left RLN and left RLNP. The median size of the left RLN was 1.51 mm. We found that the incidence of postoperative left RLNP (Clavien-Dindo classification ≥1) was significantly higher (71% vs. 24%; P < 0.001) in thin RLNs (≤1.5 mm) than in thick RLNs (>1.5 mm). Thin RLN (P < 0.001), female sex (P = 0.025), and being overweight (P = 0.034) were identified as significant independent risk factors for postoperative RLNP. RLNP more easily occurred when the RLN was thin. It is difficult to confirm occurrence of postoperative RLNP before and at extubation. Therefore, it is helpful to know its risk factors including size of RLN.

Abstract
Background Oesophagectomy has a high risk of postoperative morbidity. The impact of postoperative complications on overall survival of oesophageal cancer remains unclear. This meta‐analysis addressed the impact of complications on long‐term survival following oesophagectomy. Methods A search of PubMed and Cochrane Library databases was undertaken for systematic review of papers published between January 1995 and August 2016 that analysed the relation between postoperative complications and long‐term survival. In the meta‐analysis, data were pooled. The main outcome was overall survival (OS). Secondary endpoints included disease‐free (DFS) and cancer‐specific (CSS) survival. Results A total of 357 citations was reviewed; 21 studies comprising 11 368 patients were included in the analyses. Overall, postoperative complications were associated with significantly decreased 5‐year OS (hazard ratio (HR) 1·16, 95 per cent c.i. 1·06 to 1·26; P = 0·001) and 5‐year CSS (HR 1·27, 1·09 to 1·47; P = 0·002). Pulmonary complications were associated with decreased 5‐year OS (HR 1·37, 1·16 to 1·62; P < 0·001), CSS (HR 1·60, 1·35 to 1·89; P < 0·001) and 5‐year DFS (HR 1·16, 1·00 to 1·33; P = 0·05). Patients with anastomotic leakage had significantly decreased 5‐year OS (HR 1·20, 1·10 to 1·30; P < 0·001), 5‐year CSS (HR 1·81, 1·11 to 2·95; P = 0·02) and 5‐year DFS (HR 1·13, 1·02 to 1·25; P = 0·01). Conclusion Postoperative complications after oesophagectomy, including pulmonary complications and anastomotic leakage, decreased long‐term survival.

Abstract
The present study examined whether Lactobacillus casei strain Shirota (LcS) improves sleep quality under psychological stress. A double-blind, placebo-controlled trial was conducted in healthy 4th year medical students exposed to academic examination stress. The trial was repeated over two consecutive years in different groups of students, and the data were pooled. For 8 weeks prior to and 3 weeks after a national standardised examination, a total of 48 and 46 subjects received a daily dose of 100 ml of LcS-fermented milk or non-fermented placebo milk, respectively. Study measures included subjective anxiety, overnight single-channel electroencephalography (EEG) recordings, and the Oguri-Shirakawa-Azumi (OSA) sleep inventory scores of subjective sleep quality. Total OSA scores were significantly lower than baseline on the day before the exam and recovered after the exam, indicating a stress-induced decline in sleep quality. There was a significant positive effect of LcS treatment on OSA factors for sleepiness on rising and sleep length. Sleep latency measured by EEG lengthened as the exam approached in the placebo group but was significantly suppressed in the LcS group. The percentage of stage 3 non-REM (N3) sleep decreased in the placebo group as the exam approached, whereas it was maintained in the LcS group throughout the trial. Delta power during the first sleep cycle, measured as an index of sleep intensity, increased as the exam approached in the LcS group and was significantly higher than in the placebo group. These findings suggest that daily consumption of LcS may help to maintain sleep quality during a period of increasing stress. The observed retention of N3 sleep and increased delta power in the LcS group may have contributed to higher perceived sleep satisfaction.

Abstract
Clinical application of mesenchymal stem cells (MSCs) represents a potential novel therapy for currently intractable deteriorating diseases or traumatic injuries, including myocardial infarction. However, the molecular mechanisms of the therapeutic effects have not been precisely revealed. Herein, we report that conditioned media (CM) from rat adipose tissue-derived MSCs (ASCs) protected adult cardiomyocytes from oxygen/glucose deprivation (OGD)-induced cell death. We focused on furin/PCSK protease activity in ASC-CM because many therapeutic factors of MSCs and soluble cardioprotective factors include the PCSK cleavage site. We found that recombinant furin protected cardiomyocytes from OGD-induced cell death. The ASC-CM had potent furin/PCSK protease activity and the cardioprotective effect of the CM from ASCs in the OGD-assay was abolished by an inhibitor of the furin/PCSK-like enzyme. Microarray analysis and Western blot analysis showed PCSK5A, the secreted type of PCSK5, is the most abundantly secreted PCSK among 7 PCSK family members in ASC. Finally, knockdown of PCSK5A in ASCs decreased both the furin/PCSK protease activity and cardioprotective activity in the CM. These findings indicate an involvement of furin/PCSK-type protease(s) in the anti-ischemic activity of ASCs, and suggest a new mechanism of the therapeutic effect of MSCs. ASC-CM protects against OGD-induced cell death of adult cardiomyocytes. Furin/PCSK enzyme activity is protective against OGD-induced cell death. PCSK5A is the main component of cardioprotective activity of ASC-CM.

Abstract
BACKGROUND This study aimed to examine the effects of Lactobacillus casei strain Shirota (LcS) on gut-brain interactions under stressful conditions. METHODS Three double-blind, placebo-controlled trials were conducted to examine the effects of LcS on psychological and physiological stress responses in healthy medical students under academic examination stress. Subjects received LcS-fermented milk or placebo daily for 8 weeks prior to taking a national standardized examination. Subjective anxiety scores, salivary cortisol levels, and the presence of physical symptoms during the intervention were pooled and analyzed. In the animal study, rats were given feed with or without LcS for 2 weeks, then submitted to water avoidance stress (WAS). Plasma corticosterone concentration and the expression of cFos and corticotropin releasing factor (CRF) in the paraventricular nucleus (PVN) were measured immediately after WAS. In an electrophysiological study, gastric vagal afferent nerve activity was monitored after intragastric administration of LcS to urethane-anesthetized rats. KEY RESULTS Academic stress-induced increases in salivary cortisol levels and the incidence rate of physical symptoms were significantly suppressed in the LcS group compared with the placebo group. In rats pretreated with LcS, WAS-induced increases in plasma corticosterone were significantly suppressed, and the number of CRF-expressing cells in the PVN was reduced. Intragastric administration of LcS stimulated gastric vagal afferent activity in a dose-dependent manner. CONCLUSIONS & INFERENCES These findings suggest that LcS may prevent hypersecretion of cortisol and physical symptoms under stressful conditions, possibly through vagal afferent signaling to the brain and reduced stress reactivity in the PVN.

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
This pilot study investigated the effects of the probiotic Lactobacillus casei strain Shirota (LcS) on psychological, physiological, and physical stress responses in medical students undertaking an authorised nationwide examination for promotion. In a double-blind, placebo-controlled trial, 24 and 23 healthy medical students consumed a fermented milk containing LcS and a placebo milk, respectively, once a day for 8 weeks until the day before the examination. Psychophysical state, salivary cortisol, faecal serotonin, and plasma L-tryptophan were analysed on 5 different sampling days (8 weeks before, 2 weeks before, 1 day before, immediately after, and 2 weeks after the examination). Physical symptoms were also recorded in a diary by subjects during the intervention period for 8 weeks. In association with a significant elevation of anxiety at 1 day before the examination, salivary cortisol and plasma L-tryptophan levels were significantly increased in only the placebo group (P<0.05). Two weeks after the examination, the LcS group had significantly higher faecal serotonin levels (P<0.05) than the placebo group. Moreover, the rate of subjects experiencing common abdominal and cold symptoms and total number of days experiencing these physical symptoms per subject were significantly lower in the LcS group than in the placebo group during the pre-examination period at 5-6 weeks (each P<0.05) and 7-8 weeks (each P<0.01) during the intervention period. Our results suggest that the daily consumption of fermented milk containing LcS may exert beneficial effects preventing the onset of physical symptoms in healthy subjects exposed to stressful situations.

Abstract
Abstract
(Purpose)
Considering the dramatic increase in average life expectancy throughout the world, the management of super-elderly patients over 80 years old (SEP) with breast cancer has become a global issue. However, there have been few clinical trials for SEP until now. The reasons for this were a small population, unpredictable prognosis, a large number of non-cancer-related deaths and a lower function of multiple organs in SEP. Surgical treatment or post-operative treatment based on evidence of clinical trials for SEP has also not been unclear. We hypothesized that the outcome of SEP with breast cancer compared with other ages were similarly depended on the breast cancer subtypes.
The aim of this study was to clarify the breast cancer related survival (BRS) rate and overall survival (OS) rate at 5years for SEP according to breast cancer subtype.
(Methods)
We retrospectively analyzed 407 patients over 80 years old at initial operation between April, 1994 and April 2015 from 4 institutions of Chiba Youth Breast Oncology Research Group.
Overall, 366 patients with stage I to Stage IIIc were included.
41 patients with Stage 0 or IV were excluded in this study.
We compared the clinical characteristics, OS and BRS rates among the breast cancer subtype: such as ER positive HER2 negative (ER group), ER negative HER2 negative (TN group), ER negative HER2 positive (HER2 group) and ER positive HER2 positive (ER/HER2 group).
Univariate and multivariate analyses were performed to identify the factors of Tumor size, Lymph node, Ly, ER, HER2 and characteristics, associated with the OS and BRS.
(Results)
The median age of the 366 patients was 83 years (range 80-96 years).The median follow-up duration was 32 months (range, 2-120).
During the follow-up period, 25 (9.4%) patients in the ER group, 19 (27.5%) in TN group, 4 (22.2%) in HER2 group and 2 (20.0%) patients in ER-HER2 group died.
The 5 year OS and BRS rates were 89.2%, 97.1% in ER group, 64.6%, 81.2% in TN group, 61.5%,33.3% in HER2 group and 83.3%, 100% in ER-HER2 group, respectively.
Univariate and multivariate analyses revealed that ER was one prognostic factor to OS and BRS.
ER positive patients treatment with Aromatase inhibitor had significantly longer survival rates than treatment with Tamoxifen or no treatment (p=0.05).
There were no significant differences in OS or BRS of TN patients according to the use of chemotherapy (n=7) versus non treatment (n=61).
(Conclusions)
The prognosis and clinical course of super elderly patients with breast cancer depended on subtype.
Adjuvant therapy for ER group was one prognostic factor to OS and BRS.

Abstract
Differential cross sections of isoscalar and isovector spin-M1 (0(+)→1(+)) transitions are measured using high-energy-resolution proton inelastic scattering at E(p)=295 MeV on (24)Mg, (28)Si, (32)S, and (36)Ar at 0°-14°. The squared spin-M1 nuclear transition matrix elements are deduced from the measured differential cross sections by applying empirically determined unit cross sections based on the assumption of isospin symmetry. The ratios of the squared nuclear matrix elements accumulated up to E(x)=16 MeV compared to a shell-model prediction are 1.01(9) for isoscalar and 0.61(6) for isovector spin-M1 transitions, respectively. Thus, no quenching is observed for isoscalar spin-M1 transitions, while the matrix elements for isovector spin-M1 transitions are quenched by an amount comparable with the analogous Gamow-Teller transitions on those target nuclei.

Abstract
BACKGROUND High-mobility group box chromosomal protein 1 (HMGB1) has recently been identified as an important mediator of various kinds of acute and chronic inflammation. A method for efficiently removing HMGB1 from the systemic circulation could be a promising therapy for HMGB1-mediated inflammatory diseases. MATERIALS AND METHODS In this study, we produced a new adsorbent material by chemically treating polystyrene fiber. We first determined whether the adsorbent material efficiently adsorbed HMGB1 in vitro using a bovine HMGB1 solution and a plasma sample from a swine model of acute liver failure. We then constructed a column by embedding fabric sheets of the newly developed fibers into a cartridge and tested the ability of the column to reduce plasma HMGB1 levels during a 4-hour extracorporeal hemoperfusion in a swine model of acute liver failure. RESULTS The in vitro adsorption test of the new fiber showed high performance for HMGB1 adsorption (96% adsorption in the bovine HMGB1 solution and 94% in the acute liver failure swine plasma, 2 h incubation at 37°C; p < 0.05 vs. incubation with no adsorbent). In the in vivo study, the ratio of the HMGB1 concentration at the outlet versus the inlet of the column was significantly lower in swine hemoperfused with the newly developed column (53 and 61% at the beginning and end of perfusion, respectively) than in those animals hemoperfused with the control column (94 and 93% at the beginning and end of perfusion, respectively; p < 0.05). Moreover, the normalized plasma level of HMGB1 was significantly lower during perfusion with the new column than with the control column (p < 0.05 at 1, 2, and 3 h after initiation of perfusion). CONCLUSION These data suggest that the newly developed column has the potential to effectively adsorb HMGB1 during hemoperfusion in swine.

Abstract
A 22-week fetus presented with a large left ventricular aneurysm, 24 × 21 × 18 mm in size, detected by abnormal four-chamber view, and severe fetal hydrops with pericardial effusion, ascites and skin edema. The aneurysm was thin-walled, hypokinetic, and had enlarged with gestational age, causing compression of the lung. Although the left ventricular function had progressively impaired as expressed by increase in Tei index, hydrops had resolved by 32 weeks of gestation, probably because of maternal digoxin therapy and successful compensation by the right ventricle, as represented by retrograde blood flow in the distal aortic arch via the patent arterial duct. Because of the significant risk of severe cardiorespiratory failure, we transported the mother to a neonatal cardiac surgical center at 38 weeks of gestation. Indeed, the baby showed severe cardiopulmonary failure after birth, showing 100% of cardiothoracic ratio on the chest X-ray film, but was saved by the successful Dor procedure, including surgical resection of the aneurysm at 10 h of life. In this case, serial echocardiographic evaluation can allow us to monitor the hemodynamics and lead to successful postnatal management.

Abstract
BACKGROUND High-mobility group box 1 (HMGB1) is a monocyte-derived late-acting inflammatory mediator, which is released in conditions such as shock, tissue injury and endotoxin-induced lethality. In this study, we determined the plasma and hepatic tissue levels of HMGB1 in patients with acute liver failure (ALF). PATIENTS AND METHODS We determined the plasma levels of HMGB1 and aspartate aminotransferase (AST) in 7 healthy volunteers (HVs), 40 patients with liver cirrhosis (LC), 37 patients with chronic hepatitis (CH), 18 patients with severe acute hepatitis (AH), and 14 patients with fulminant hepatitis (FH). The 14 patients with FH were divided into two subgroups depending upon the history of plasma exchange (PE) before their plasma sample collection. The hepatic levels of HMGB1 were measured in tissue samples from 3 patients with FH who underwent living-donor liver transplantation and from 3 healthy living donors. Hepatic tissue samples were also subjected to immunohistochemical examination for HMGB1. RESULTS The plasma levels of HMGB1 (ng/ml) were higher in patients with liver diseases, especially in FH patients with no history of PE, than in HVs (0.3 ± 0.3 in HVs, 4.0 ± 2.0 in LC, 5.2 ± 2.6 in CH, 8.6 ± 4.8 in severe AH, 7.8 ± 2.7 in FH with a history of PE, and 12.5 ± 2.6 in FH with no history of PE, p < 0.05 in each comparison). There was a strong and statistically significant relationship between the mean plasma HMGB1 level and the logarithm of the mean AST level (R = 0.900, p < 0.05). The hepatic tissue levels of HMGB1 (ng/mg tissue protein) were lower in patients with FH than in healthy donors (539 ± 116 in FH vs. 874 ± 81 in healthy donors, p < 0.05). Immunohistochemical staining for HMGB1 was strong and clear in the nuclei of hepatocytes in liver sections from healthy donors, but little staining in either nuclei or cytoplasm was evident in specimens from patients with FH. CONCLUSION We confirmed that plasma HMGB1 levels were increased in patients with ALF. Based on a comparison between HMGB1 contents in normal and ALF livers, it is very likely that HMGB1 is released from injured liver tissue.

Abstract
Members of the triggering expressed on myeloid cells (Trem) receptor family fine-tune inflammatory responses. We previously identified one of these receptors, called Treml4, expressed mainly in the spleen, as well as at high levels by CD8α(+) dendritic cells and macrophages. Like other Trem family members, Treml4 has an Ig-like extracellular domain and a short cytoplasmic tail that associates with the adaptor DAP12. To follow up on our initial results that Treml4-Fc fusion proteins bind necrotic cells, we generated a knockout mouse to assess the role of Treml4 in the uptake and presentation of dying cells in vivo. Loss of Treml4 expression did not impair uptake of dying cells by CD8α(+) dendritic cells or cross-presentation of cell-associated Ag to CD8(+) T cells, suggesting overlapping function between Treml4 and other receptors in vivo. To further investigate Treml4 function, we took advantage of a newly generated mAb against Treml4 and engineered its H chain to express three different Ags (i.e., OVA, HIV GAGp24, and the extracellular domain of the breast cancer protein HER2). OVA directed to Treml4 was efficiently presented to CD8(+) and CD4(+) T cells in vivo. Anti-Treml4-GAGp24 mAbs, given along with a maturation stimulus, induced Th1 Ag-specific responses that were not observed in Treml4 knockout mice. Also, HER2 targeting using anti-Treml4 mAbs elicited combined CD4(+) and CD8(+) T cell immunity, and both T cells participated in resistance to a transplantable tumor. Therefore, Treml4 participates in Ag presentation in vivo, and targeting Ags with anti-Treml4 Abs enhances immunization of otherwise naive mice.

Abstract
Elastofibroma is a tumor that is localized mainly at the subscapular region. We report 2 cases of subscapular elastofibromas. Case 1, 75-year-old woman was seen at the hospital because of a left dorsal tumor. Computed tomography (CT) scan revealed the tumor of 6 cm in diameter in the inferior angle of left scapula. The patient underwent excision of the tumor. Case 2, 90-year-old man underwent excision a tumor of 5 cm in diameter in the inferior angle of right scapula simultaneously with the operation of right lung cancer. Histological examinations showed increased elastic fiber with elastica van Gieson staining. These specimens confirmed the diagnosis of elastofibroma There have been no signs of recurrence after surgery.

The double-differential cross sections for the 48Ca(p,n) and 48Ti(n,p) reactions were measured at 300 MeV. A multipole decomposition technique was applied to the spectra to extract the Gamow-Teller (GT) components. The integrated GT strengths up to an excitation energy of 30 MeV in 48Sc are 15.3+/-2.2 and 2.8+/-0.3 in the (p,n) and (n,p) spectra, respectively. In the (n,p) spectra additional GT strengths were found above 8 MeV where shell models within the fp shell-model space predict almost no GT strengths, suggesting that the present shell-model description of the nuclear matrix element of the two-neutrino double-beta decay is incomplete.

Abstract
Dendritic cells (DCs) are professional APCs that can control immune responses against self and altered self, typically foreign, determinants. DCs can be divided into several subsets, including CD8alpha(+) and CD8alpha(-) DCs. These subsets possess specific functions. For example, mouse splenic CD8alpha(+), but not CD8alpha(-) DCs selectively take up dying cells and cross-present cell-associated Ags to naive T cells. In this study, we identified genes that were more expressed in CD8alpha(+) than CD8alpha(-) DCs by microarray analysis. Only one of these genes, when the extracellular domains were linked to human IgG Fc domain, could bind to late apoptotic or necrotic cells. This gene was a new member of the triggering receptor expressed on myeloid cells (Trem) family, Trem-like 4 (Treml4). Treml4 mRNA and protein, the latter detected with a new mAb, were predominantly expressed in spleen. Treml4, like other Trem family members, could associate with the adaptor molecule DNAX activation protein 12 kDa, but neither DNAX activation protein 10 kDa nor FcRgamma. Consistent with the microarray data, we confirmed that Treml4 protein was more expressed on CD8alpha(+) than CD8alpha(-) DCs, and we also found that Treml4 was expressed at high levels on splenic macrophages in spleen, particularly red pulp and marginal metallophilic macrophages. In addition, Treml4 expression on DCs was not changed after maturation induced by TLR ligands. Thus, Treml4 is a new Trem family molecule that is abundantly expressed on CD8alpha(+) DCs and subsets of splenic resident macrophages, and can recognize dead cells by different types of phagocytes in spleen.

Abstract
BACKGROUND/AIMS Management of patients with recurrent intrahepatic cholangiocarcinoma (ICC) following surgical resection is difficult, and surgical resection is rarely indicated. We retrospectively reviewed patients with recurrent intrahepatic cholangiocarcinoma. METHODOLOGY Between April 1998 and March 2007, 57 consecutive patients with ICC underwent surgical resection. Mode of recurrence and treatment of recurrent tumors, especially surgical resection for these tumors, in patients with cancer recurrence were evaluated. RESULTS 37 (65%) patients experienced tumor recurrence. Out of these patients, 24 underwent some type of cancer-directed therapy, including 9 patients (24%) for whom surgical resection was attempted: the latter included 4 hepatic resections, 2 pulmonary resections, 2 tumor resections, and 1 gastric resection. For 6 patients with recurrent tumor in the liver or the lung, microscopic complete resection was achieved, while incomplete resection was resulted in the remaining 3 patients. No postoperative mortality was encountered. Among patients with complete resection, 3 are alive without disease 32, 39 and 77 months after the second operation, one has lived with disease for 13 months, and 2 died of disease after 22 and 26 months. No significant difference in overall survival was observed between patients undergoing primary and second surgical resections, calculated from the primary and the second operations, respectively. CONCLUSIONS Repeated surgical resection for recurrent ICC can be performed with acceptable morbidity, and affords selected patients a chance for long-term survival.
