Abstract
The immune system is sensitive to many chemicals. Among dioxin compounds, 2,3,7,8-tetrachlorodizenzo-p-dioxin (TCDD) is the most toxic environmental pollutant. The effects of perinatal maternal exposure to dioxins may persist into childhood. However, there have been no reports to date on the effects of exposure to dioxins during infancy, when the immune organs are developing. Therefore, we investigated the effects of TCDD and antigen exposure during lactation on immune function, especially antibody production capacity, in adult mice. Beginning the day after delivery, lactating mothers were orally administered TCDD or a mixture of TCDD and ovalbumin (OVA) daily for 4 weeks, until the pups were weaned. At 6 weeks of age, progeny mice were orally administered OVA daily for 10 weeks, while non-progeny mice were orally administered OVA or a mixture of TCDD and OVA daily for 10 weeks. Production of serum OVA-specific IgG was examined weekly. The amount of TCDD transferred from the mother to the progeny via breast milk was determined by measuring TCDD in the gastric contents of the progeny. A trend toward increasing IgA titer was observed in TCDD-treated mice, and production of IgE was observed only in progeny whose mothers were treated with TCDD and OVA. The results suggest that exposure to TCDD and OVA in breast milk can affect immune function in newborns.

Long-term orally exposure of dioxins affects antigen-specific antibody production in mice. Toxicol Rep 2022; 9:53-57. [PMID: 35004181 PMCID: PMC8717457 DOI: 10.1016/j.toxrep.2021.12.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2021] [Revised: 12/15/2021] [Accepted: 12/18/2021] [Indexed: 11/24/2022] Open
Abstract
Antigen-specific (OVA) antibody production in the serum increased dose-dependently by TCDD concentrations below 500 ng/kg after long-term (10 weeks) exposure. Similar increases were seen in fecal and vaginal samples but were not significant. Th1 and Th2 lymphocyte responses, as determined by antibody and cytokine production, also significantly increased dose-dependently up to 500 ng/kg TCDD, and the Th1/Th2 balance was shifted toward Th1.
Dioxins are persistent environmental toxins that are still present in the food supply despite strong efforts to minimize exposure. Dioxins ingested by humans accumulate in fat and are excreted very slowly, so their long-term effects at low concentrations are a matter of concern. It is necessary to consider long-term, low-dose continuous administration under conditions that are as close as possible to a person's diet. In this study, we orally administered 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), the most common dioxin, at low doses in mice and observed the immunological effects. We found that antigen-specific (OVA) antibody production in the serum increased dose-dependently by TCDD concentrations below 500 ng/kg after long-term (10 weeks) exposure. Similar increases were seen in fecal and vaginal samples but were not significant. Th1 and Th2 lymphocyte responses, as determined by antibody and cytokine production, also significantly increased dose-dependently up to 500 ng/kg TCDD, and the Th1/Th2 balance was shifted toward Th1. These results indicate that low-dose, long-term TCDD exposure results in immunological abnormalities, perhaps by increasing antigen permeability. Different doses of dioxins may have opposing effects, being immunostimulatory at low doses (100 ng/kg/day) and immunosuppressive at high doses (500 ng/kg/day).

Abstract
Abstract
Background
Obesity carries independent risk for incident atrial fibrillation (AF), although the impact of abdominal fat distribution on LA morphological and functional remodeling is not fully elucidated. Speckle-tracking echocardiography is a novel and sensitive tool that allows quantification and detection of subtle alterations in left atrial (LA) phasic function.
Purpose
This study aimed to investigate whether increased visceral adiposity is independently associated with impaired LA phasic function in a community-based cohort.
Methods
We included 527 participants without overt cardiac disease who underwent laboratory testing, abdominal computed tomographic examination and speckle-tracking echocardiography. Abdominal adiposity was quantitatively assessed as visceral fat area (VFA) and subcutaneous fat area (SFA) at the level of the umbilicus. Speckle-tracking echocardiography was performed to assess LA phasic function including reservoir, conduit and pump strain as well as left ventricular global longitudinal strain (LVGLS).
Results
Mean age was 57±10 years and 362 of the participants (69%) were men. LA reservoir and conduit strain were decreased according to the VFA quartiles (both p<0.05), whereas there was no significant difference in LA volume index and LA pump strain. When stratified by SFA, there was no significant differences in LA volume index and all LA phasic strain across the quartiles. In multivariable analysis, VFA as continuous variable was significantly associated with LA conduit strain, independent of traditional cardiovascular risk factors, pertinent laboratory parameters and LV morphology and function including LVGLS (standardized b=−0.146, p=0.011). Representative cases are shown in the Figure.
Conclusion
In a sample of the general population, VFA accumulation was independently associated with worse LA conduit strain, which may be involved in the pathophysiological mechanism of obesity-related AF.

Abstract
Abstract
Background
Although carotid intima-media thickness (IMT) is an established marker of atherosclerosis and carries independent risk for cardiovascular disease, its possible association with subclinical cardiac dysfunction has not been extensively evaluated. Left ventricular global longitudinal strain (LVGLS) and peak left atrial longitudinal systolic strain (PALS) can detect subclinical left heart dysfunction.
Purpose
This study aimed to investigate the association between carotid IMT and subclinical left heart dysfunction in a large sample of the general population without overt cardiac disease.
Methods
We examined 1,161 participants who underwent extensive cardiovascular examination. Ultrasonography of common carotid artery was performed for the measurement of maximal carotid IMT. LVGLS and PALS were assessed by 2-dimensional speckle-tracking echocardiography.
Results
Mean age was 62±12 years, and 56% were male. The prevalence of abnormal LVGLS (>−18.6%) and PALS (<31.4%) was greatest in the upper quartile of carotid IMT (both p<0.001; Figure). In multivariable analyses, carotid IMT was associated with abnormal LVGLS (adjusted odds ratio = 1.33 per 1SD increase of IMT, p=0.003) as well as PALS (adjusted odds ratio = 1.33 per 1SD increase of IMT, p=0.005) independent of traditional cardiovascular risk factors, echocardiographic parameters including LV ejection fraction, LV mass index and diastolic dysfunction, and pertinent laboratory parameters. The independent association between carotid IMT and PALS persisted even after adjustment for LVGLS. When carotid IMT was examined as a categorical variable, the upper quartile of carotid IMT carried a significant risk of abnormal LVGLS and PALS in a fully-adjusted model including echocardiographic and laboratory parameters (adjusted odds ratio 2.27 and 3.03 vs. lower quartile, both p<0.01).
Conclusion
Participants with increased IMT had significantly impaired LV and LA function in an unselected community-based cohort. This association may be involved in the higher incidence of cardiovascular disease in individuals with increased carotid IMT.

Sex-specific difference in the association between arterial stiffness and subclinical left ventricular dysfunction. Eur Heart J 2020.

Abstract
Abstract
Background
Increased arterial stiffness has been proposed as one of the key mechanisms of incident heart failure with preserved ejection fraction (HFpEF). However, the possible association between arterial stiffness and subclinical left ventricular (LV) dysfunction and possible sex-specific differences remain unclarified. LV strain is emerging as a highly sensitive tool to unmask early LV abnormalities.
Purpose
We investigated whether increased arterial stiffness is independently associated with subclinical LV dysfunction in a large community-based cohort without overt cardiovascular disease.
Methods
We examined 1,155 participants who underwent extensive cardiovascular examination. Speckle-tracking echocardiography was employed to assess LV global longitudinal strain (LVGLS) and circumferential strain (GCS), and arterial stiffness was assessed by cardio-ankle vascular index (CAVI).
Results
Mean age was 62±12 years, and 56% were male. CAVI as continuous variable was associated with abnormal LVGLS (>−18.6%), independent of cardiovascular risk factors and pertinent laboratory and echocardiographic parameters (adjusted odds ratio [OR] 1.23, p=0.034), whereas there was no relationship with LVGCS. In sex-stratified analysis, more pronounced association between quartiles of CAVI and abnormal LVGLS was observed in women than in men (unadjusted OR = 6.43 in women and 2.46 in men for upper quartile vs. lower quartile, both p<0.01; Figure). Multivariable analyses demonstrated that CAVI was significantly associated with abnormal LVGLS independent of cardiovascular risk factors in both sexes. However, after further adjustment for LV mass index and diastolic parameters, the independent association persisted in women (adjusted OR 1.49, p=0.041), but not in men (adjusted OR 1.15, p=0.209).
Conclusion
Increased arterial stiffness was independently associated with decreased LVGLS even in the absence of overt cardiovascular disease; a sex-specific pattern exists in the alteration of vascular-ventricular coupling, which might partially explain the greater susceptibility to HFpEF in women.

Abstract
Abstract
Background
Increased arterial stiffness is recognized as an independent risk factor for atrial fibrillation, although the pathophysiological mechanisms remain unclear. Cardio-ankle vascular index (CAVI) is emerging as an important tool to assess arterial stiffness noninvasively which is derived from the concept of stiffness β index and is less dependent on blood pressure at the time of measurement than pulse wave velocity.
Purpose
This study aimed to investigate the association of arterial stiffness with left atrial (LA) volume and phasic function in a community-based cohort.
Methods
We included 1,156 participants without overt cardiovascular disease who underwent extensive cardiovascular examination. Arterial stiffness was evaluated by CAVI. Speckle-tracking echocardiography was employed to evaluate LA phasic function including reservoir, conduit and pump strain as well as left ventricular global longitudinal strain (LVGLS).
Results
CAVI was negatively correlated with reservoir and conduit strain (r=−0.37 and −0.45, both p<0.001; Figure), whereas weakly, but positively correlated with LA volume index and pump strain (r=0.12 and 0.09, both p<0.01). In multivariable analysis, CAVI was significantly associated with reservoir and conduit strain independent of traditional cardiovascular risk factors, pertinent laboratory parameters and LV morphology and function including LVGLS (standardized β=−0.22 and −0.26, respectively, both p<0.001), whereas there was no independent association with LA volume index and pump strain. In the categorical analysis, the abnormal CAVI (≥9.0) carried the significant risk of impaired reservoir (<31.4%) and conduit (<12.4%) strain (adjusted odds ratio = 2.63 and 3.71 vs. normal CAVI, both p<0.01) in a fully-adjusted model including laboratory and echocardiographic parameters.

Conclusion
Arterial stiffness was independently associated with LA reservoir and conduit function, even in the absence of overt cardiovascular disease. This association may explain the higher incidence of atrial fibrillation in individuals with increased arterial stiffness.

Isolated Superior Mesenteric Artery Dissection Following Liver Transplant: Report of 3 Cases. Transplant Proc 2019; 51:1502-1505. [PMID: 31155183 DOI: 10.1016/j.transproceed.2019.01.113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2018] [Accepted: 01/04/2019] [Indexed: 11/18/2022]
Abstract
BACKGROUND Isolated superior mesenteric artery (SMA) dissection (SMAD) is considered a relatively rare disease. Especially, isolated SMAD following liver transplant has been rarely reported. REPORT OF CASES Among 96 consecutive adult recipients who underwent liver transplant at our institution, 3 recipients (3.1%) demonstrated isolated noncommunicating SMAD, type IV according to Sakamoto's classification. Patient characteristics are the following: mean age, 53 years (range, 49-60 years); male to female ratio, 2:1, right lobe graft to left lobe graft ratio, 2:1; operating time, 760 minutes (range, 614-880 minutes); and blood loss, 6570 mL (range, 2435-13,329 mL). New onset of abdominal pain was noted in 33.3% (1/3). The diagnosis was made by the first follow-up computed tomography scan after liver transplant. The mean distance between the proximal end of SMAD and the root of SMA was 21.3 mm (range, 9-40 mm). There were no signs of ischemic changes in the small intestine in any of the 3 patients. Thus, conservative managements such as anticoagulation therapy were performed without other aggressive interventions. One patient died because of subarachnoid hemorrhage. In the other 2 patients, SMAD disappeared at 6 months following the diagnosis. DISCUSSION The morbidity of isolated SMAD is around less than 0.1% at the autopsy. Compared with this result, we found significantly higher morbidity rate in liver transplant recipients. It is true that mechanical stress from retraction of the stomach to the caudal end including the root of SMA may play an important role in the onset of SMA dissection. CONCLUSION Isolated SMA dissection following living donor liver transplant is a rare but potentially life-threatening condition. It is required to ascertain whether emergency revascularization should be considered.

Complex toxicity as disruption of adipocyte or osteoblast differentiation in human mesenchymal stem cells under the mixed condition of TBBPA and TCDD. Toxicol Rep 2018; 5:737-743. [PMID: 29928592 PMCID: PMC6008500 DOI: 10.1016/j.toxrep.2018.06.007] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2018] [Revised: 05/04/2018] [Accepted: 06/11/2018] [Indexed: 11/18/2022] Open
Abstract
People are frequently and unintentionally exposed to many chemical compounds, such as environmental pollutants and endocrine-disrupting chemicals (EDCs), in food and from the atmosphere. In particular, endocrine-disrupting TBBPA and dioxins are found in human breast milk and in the body. Conventional studies evaluate toxicity by administering a single substance to cells or animals, but evaluation of the toxicity of mixtures of these ingested compounds is essential for “true” toxicological assessment. We evaluated toxic effects in vitro using human mesenchymal stem cells (hMSCs). TBBPA increased the number of lipid droplets, and upregulated the expression of adipocyte-related mRNA, aP2 and LPL, through a PPARγ-dependent mechanism. TCDD suppressed lipid droplets and adipocyte-related mRNA levels. Adipocyte differentiation was stimulated by TBBPA and inhibited by TCDD in a dose-dependent manner. TBBPA did not influence osteoblast differentiation, but TCDD suppressed ALP staining and activity, calcium deposition, and osteoblast-related mRNA levels. In a mixture of TBBPA and TCDD, TBBPA inhibited TCDD suppression of adipocyte and osteoblast differentiation in a dose-dependent manner. Interestingly, we observed lipid droplets in TBBPA-treated cells differentiated into osteoblasts. These results suggest that TBBPA and TCDD disrupted differentiation into adipocytes and osteoblasts and contributes to a more complete toxicological understanding of exposure to these chemical substances.

Abstract
SummaryObjective: It was the purpose of this study to determine the effects of non-esterified fatty acids (NEFA) concentrations at different time periods of the transition period as well as lactation number on metabolism, health, reproduction and milk production in dairy cows. Material and methods: This trial was conducted in a single dairy herd located in Northern Germany. Of the herd, which comprised 330 lactating Holstein cows housed in a free stall barn and fed a total mixed ration (TMR), 83 primiparous and multiparous cows were randomly selected. Animals were checked for body condition score (BCS), locomo tion score, calving data, quality of colostrum, reproductive measures, daily rectal temperature of the first 10 days post-partum (p. p.), health data and culling rates up to 200 days in milk (DIM) as well as milk production until 305 DIM. Three different time periods were considered: 3 and 1 week ante partum (a. p.); partus and 1 week p. p.; 3 weeks p. p. Results: Animals with NEFA concentrations 0.4 mmol/l ante partum had a higher risk of no ovarian activity in week 5 p. p. and of subclinical ketosis post partum than cows with lower NEFA concentrations (p < 0.05). Cows with NEFA concentrations 1.1 mmol/l in week 1 p. p., in comparison to those with lower NEFA concentrations, showed a higher prevalence of clinical ketosis (24.1% vs. 5.9%), subclinical ketosis (62.1% vs. 34.0%) and culling rate within 200 DIM (34.5% vs. 14.0%) (p < 0.05). Cows with NEFA concentrations 0.3 mmol/l at week 3 p. p. had higher 100- and 305-day milk yields than cows with lower NEFA concentrations (p < 0.05). First lactating heifers were at higher risk to loose body condition ante partum, of dystocia, fever within the first 10 DIM, metritis, clinical and subclinical ketosis as well as to develop a disease within the first 30 DIM (p < 0.05). Multipara were more likely to loose body condition after calving, to a prolonged calving to first service interval and to higher milk yields (p < 0.05). Conclusion: In conclusion increased NEFA concentrations during the transition period as well as parity can have an influence on health, production and reproduction of dairy cows.

Abstract
We investigated the reaction dynamics induced by the 7Be,8B+208Pb collisions at energies around the Coulomb barrier. Charged particles originated by both the col- lisions were detected by means of 6 ΔE-Eres telescopes of a newly developed detector array. Experimental data were analysed within the framework of the Optical Model and the total reaction cross-sections were compared together and with the 6,7Li+208Pb colli-sion data. According to the preliminary results, 7Be nucleus reactivity is rather similar to the 7Li one whereas the 8B+208Pb total reaction cross section appears to be much larger than those measured for reactions induced by the other weakly-bound projectiles on the same target.

Abstract
INTRODUCTION Myeloid-derived suppressor cells (MDSCs) play an important role in regulating allograft rejection in organ transplantation. On the other hand, CD3(+)/CD4(+)/FOXP3(+) regulatory T cells (Tregs) also are of vital importance in immunological tolerance. We previously revealed that adoptive transfer of MDSCs recruited Tregs in the spleen. However, it is still uncertain whether MDSCs are capable of recruiting Tregs to an allograft in vivo. OBJECTIVES We conducted adoptive transfer experiments of MDSCs to clarify the effects of MDSCs on Tregs in vivo. METHODS Gr-1(+)/CD11b(+) MDSCs were isolated from rapamycin-treated cardiac transplant (CTx) recipients (3 mg/kg, intraperitoneally on postoperative days [POD] 0, 2, 4, and 6) on POD 7 by magnetic-activated cell sorting (purity >95%). In murine heterotopic cardiac transplantation, 2 × 10(6) MDSCs were transferred into the graft aorta 5 minutes before reperfusion. RESULTS Flow cytometric analyses of a cardiac allograft on POD 7 showed that MDSCs derived from rapamycin-treated CTx mice (MDSCs-Rap) transfer led to significant recruitment of Tregs compared with a PBS-injected allograft. The level of programmed death ligand-1 (PD-L1) on MDSCs-Rap was higher than those from non-treated recipients. Furthermore, pathological findings also confirmed accumulation of Foxp3(+) Tregs in an allograft. CONCLUSION Induced PD-L1 on MDSCs might result in recruitment of Tregs. These results suggested that functional MDSCs possessed an ability to induce Tregs in a cardiac allograft and developed a tendency to immunological tolerance.

Abstract
Preservation of fertility has been recommended for cancer-bearing patients of reproductive age before undergoing cancer treatment. However, there are many considerations and it is difficult to preserve fertility for all patients undergoing therapy for malignancies. Female cancer survivors had lower pregnancy and live birth rates compared with others that underwent assisted reproductive technologies (ARTs). We should continue to consider the issue of infertility in patients who underwent therapies for malignancies. This is the first report of a successful live birth in a patient with a cranial tumor who underwent radiotherapy and chemotherapy after implantation of an autologous embryo. The patient was a 27-year-old Japanese woman. She was diagnosed with suprasellar germinoma at 13 years of age, and she developed panhypopituitarism after radiotherapy and chemotherapy. At 27 years of age, she began infertility treatment with in-vitro fertilization (IVF). The level of anti-Mallerian hormone (AMH) was 4.29 ng/ml. After ovarian stimulation by high purified human menopausal gonadotropin (HP-hMG), she obtained two blastocysts and became pregnant by implantation of a cryopre- served blastocyst. At 37 gestational weeks, she delivered a healthy female baby by cesarean section.

Abstract
This study was retrospectively carried out to compare the efficacy of echinocandins such as micafungin (MCFG) and caspofungin (CPFG) in the treatment of antibiotic-unresponsive febrile patients with hematologic malignancies. A total of 163 patients received either MCFG or CPFG. We evaluated the efficacy of echinocandin against fever decline in all patients. Fever decline, defined as a body temperature of less than 37.5 °C sustained for more than 48 h without scheduled antipyretic medication. Efficacy assessments showed that the incidence of fever decline was not significantly different between the MCFG and CPFG groups (P=0.599). The median number of days from the start of echinocandin administration to fever decline was 5 in both the MCFG and CPFG groups. Multivariate analysis showed that the use of anti-MRSA drugs (HR, 0.64; 95%CI, 0.45-0.90; P=0.011) and a change from echinocandins to voriconazole or liposomal-amphotericin B (HR, 0.50; 95%CI, 0.30-0.74; P<0.001) are significant risk factors for sustained fever. A significant difference (P=0.002) in incidence of fever decline was however associated with differences in the timing of anti-MRSA drug administration. The median number of days from the start of echinocandin administration to fever decline was 5 when administration of the anti-MRSA drug occurred "simultaneously or prior to echinocandin start" and 11 in the "next day or later of echinocandin start" group. In other words, starting anti-MRSA drug treatment after echinocandin treatment is a risk factor. In conclusion, MCFG and CPFG have similar efficacy as empirical antifungal agents in the treatment of antibioticunresponsive febrile patients with hematopoietic malignancies.

Abstract
Neutropenia may develop as an adverse event in patients with multiple myeloma receiving lenalidomide (LEN) plus dexamethasone (DEX) therapy. In the present study, we examined the risk factors associated with grade 3/4 neutropenia during the first cycle of LEN plus DEX therapy. We observed that hemoglobin level (≤ 8.5 g/dl) was a significant risk factor for grade 3/4 neutropenia during the first cycle of therapy (odds ratio: 19.40; 95% confidence interval: 2.68-141.00; p < 0.01). thus, our findings suggest that determining the hemoglobin level could be useful in the risk management for neutropenia in patients receiving LEN plus DEX therapy.

Abstract
BACKGROUND There is a growing tendency to perform pre-emptive kidney transplantation (PKT). However, less research has been performed on outcomes of PKT and kidney transplantation (KT) after long-term dialysis (LD). METHODS To elucidate advantages of PKT to KTLD, 96 patients who underwent living-donor KT at our university from 2000 to 2011 were enrolled for this study: 64 patients in the PKT0 (0 months dialysis) group; 14 patients in the PKT-3 group (less than 3 months dialysis); 18 patients in the LD (dialysis > 120 months) group. All recipients were assessed for patients' survival, graft survival, urinary tract infection, laboratory data, episodes of acute rejection, cytomegalovirus-related diseases, and other significant infectious diseases which required hospitalization. RESULTS Although there were no significant differences in 5-year graft survival (93.8% in PKT0, 85.7% in PKT-3, and 83.7% in control), 5-year patient survival is better in the PKT0 group (96.9%) and the PKT-3 group (92.9%) compared to 88.9% in the control group. Urinary tract infection is clearly correlated with the LD group (44.4% in the LD group vs 19.2% in the PKT group) primarily due to atrophic bladder and subsequent vesicoureteral reflux. Slightly higher rates of acute rejection were found in the PKT groups (30.8% vs 26.3%). CONCLUSION This study revealed that there are both advantages and disadvantages of PKT. It is clear, therefore, that PKT can be recommended for end-stage renal disease patients provided enough attention is paid to the onset of acute rejection.

Evaluation of renal allograft fibrosis by transient elastography (Fibro Scan). Transplant Proc 2015; 47:640-3.

Abstract
BACKGROUND Chronic allograft injury (CAI) is one of the most important factors for graft failure after renal transplantation. Protocol biopsy is the most valuable tool for revealing subclinical renal allograft failure. Transient elastography (TE) is a noninvasive technique that has shown utility for the assessment of hepatic and renal fibrosis. This study sought to evaluate whether TE was a viable and effective method for the assessment of renal allograft failure. PATIENTS AND METHODS Thirty-five patients underwent TE by Fibro Scan (Echosense, Paris, France). Biopsies were performed in 27 patients, allowing classification according to Banff chronic changes in the interstitium grade 0, grade 1 or grade 2. RESULTS Measurement of parenchymal stiffness was successful in 31 of 35 patients (91%). Stiffness was significantly correlated with interstitial fibrosis (P < .05) and inversely related with estimated glomerular filtration rate (eGFR; P < .05). Stiffness values of patients with eGFR > 50 mL/min were lower than those of patients with eGFR < 50 mL/min (P < .05). Patients classed as CAI Banff grade 0 had significantly less parenchymal stiffness than patients with Banff grade 1 or grade 2 CAI (P < .05). Parenchymal stiffness measured by TE reflected interstitial fibrosis in renal allograft. CONCLUSION Assessment of parenchymal renal allograft stiffness by TE was effective for identifying patients with CAI who may subsequently benefit from biopsy and modification of the immunosuppressive regimen. Assessment of parenchymal renal allograft stiffness can be effective for identifying patients with CAI. TE has the potential to reduce the number of renal allograft biopsies required for accurate assessment of CAI.

Rapamycin Prolongs Cardiac Allograft Survival in a Mouse Model by Inducing Myeloid-Derived Suppressor Cells. Am J Transplant 2015; 15:2364-77.

Abstract
Mammalian target of rapamycin (mTOR) inhibitors are the main immunosuppressive drugs for organ transplant recipients. Nevertheless, the mechanisms by which mTOR inhibitors induce immunosuppression is not fully understood. Myeloid-derived suppressor cells (MDSCs) maintain host immunity; however, the relationship between mTOR inhibitors and MDSCs is unclear. Here, the results from a murine cardiac transplantation model revealed that rapamycin treatment (3 mg/kg, intraperitoneally on postoperative days 0, 2, 4, and 6) led to the recruitment of MDSCs and increased their expression of inducible nitric oxide synthase (iNOS). Immunohistochemical analysis revealed that rapamycin induced the migration of iNOS-expressing MDSCs into the subintimal space within the allograft vessels, resulting in a significant prolongation of graft survival compared with that in the untreated group (67 days vs. 7 days, respectively). These effects were counterbalanced by the administration of an anti-Gr-1, which reduced allograft survival to 21 days. Moreover, adoptive transcoronary arterial transfer of MDSCs from rapamycin-treated recipients prolonged allograft survival; this increase was reversed by the anti-Gr-1 antibody. Finally, co-administration of rapamycin and a mitogen-activated protein kinase kinase (MEK) inhibitor trametinib reversed rapamycin-mediated MDSC recruitment. Thus, the mTOR and Raf/MEK/extracellular signal regulated kinase (ERK) signaling pathways appear to play an important role in MDSC expansion.

Abstract
Tetrabromobisphenol A (TeBBPA) is widely used type of brominated flame retardant. In this study, we newly synthesized materials for the debrominated congeners, 2,2',6-tribromobisphenol A (TriBBPA), 2,2'-dibromobisphenol A (2,2'-DiBBPA), 2,6-dibromobisphenol A (2,6-DiBBPA), and 2-monobromobisphenol A (MoBBPA) and evaluated the actual extent of contamination with bisphenol A (BPA), TeBBPA and debrominated congeners in Japanese breast milk samples. TriBBPA was detected at higher levels than that of TeBBPA, while DiBBPA and MoBBPA were detected at lower levels than that of TeBBPA. This observation suggested that humans are exposed to debrominated congeners, which might cause adverse effects. Contamination of the congeners in breast milk was concern about risk infant health, having vulnerable defense system. As pilot study by in vitro experiment, we assessed the toxic potency of debrominated congeners by studying their effect on adipocyte differentiation in 3T3-L1 cells. We observed 2,6-DiBBPA, TriBBPA and TeBBPA elevated the lipid accumulation and adipocyte-specific protein 2 expression in a manner dependent on the number of substituted bromines. Moreover, PPARγ transcriptional activities increased in a dose-dependent manner in the presence of 2,6-DiBBPA and TriBBPA as well as TeBBPA. Our study clarified that TeBBPA and its debrominated congeners accumulated in breast milk and the debrominated congeners promoted adipocyte differentiation, showing that a comprehensive evaluation of the influences of these compounds including the debrominated congeners of TeBBPA on health in infants is necessary.

Abstract
Coplanar polychlorinated/brominated biphenyls (Co-PXBs) belong to a class of structurally similar chemicals known as polyhalogenated aromatic hydrocarbons. We found that the milk of Japanese primiparous and multiparous mothers was similarly contaminated with Co-PXB congeners. Co-PXBs time- and dose-dependently increased ethoxyresorufin-O-deethoxylase (EROD activity) in HepG2 cells. The EROD activity of liver microsomes collected from C57BL/6 mice exposed to these congeners substituted with one or two, and with three or five bromine atoms time-dependently decreased and increased, respectively. These results indicate that introducing bromine into the chemical frame of a polychlorinated biphenyl tends to increase CYP1A activity in vitro and in vivo and that the number substituted bromine atoms alters the metabolism profiles. If Co-PXBs are more toxic than Co-PCBs, our findings suggest that the TEQ of Co-PXBs is important for human health risk.

Abstract
The Faculty of Pharmaceutical Sciences, Setsunan University, offers the Self-improvement and Participatory Career Development Education Program: Internship and Volunteer Training Experience for Pharmacy Students to third-year students. We previously reported that the training experience was effective in cultivating important attributes among students, such as a willingness to learn the aims of pharmacists, an awareness of their own role as healthcare workers, and a desire to reflect on their future careers and lives. A follow-up survey of the participants was carried out three years after the training experience. The questionnaire verified that the training experience affected attendance at subsequent lectures and course determination after graduation. We confirmed the relationship between the participants' degree of satisfaction with the training experience and increased motivation for attending subsequent lectures. Through the training experience, participants discovered future targets and subjects of study. In addition, they became more interested in subsequent classroom lessons and their future. The greater the participants' degree of satisfaction with their training experience, the more interest they took in practical training and future courses. The present study clarified that the training experience was effective in cultivating important attributes such as a willingness to learn and an interest in future courses. Moreover, the training positively affected the course determination after graduation.

Abstract
BACKGROUND The DSM-5 Obsessive-Compulsive Spectrum Sub-Workgroup is recommending the creation of a new diagnostic category named Hoarding Disorder (HD). The validity and acceptability of the proposed diagnostic criteria have yet to be formally tested. METHOD Obsessive-compulsive disorder/hoarding experts and random members of the American Psychiatric Association (APA) were shown eight brief clinical vignettes (four cases meeting criteria for HD, three with hoarding behaviour secondary to other mental disorders, and one with subclinical hoarding behaviour) and asked to decide the most appropriate diagnosis in each case. Participants were also asked about the perceived acceptability of the criteria and whether they supported the inclusion of HD in the main manual. RESULTS Altogether, 211 experts and 48 APA members completed the survey (30% and 10% response rates, respectively). The sensitivity and specificity of the HD diagnosis and the individual criteria were high (80-90%) across various types of professionals, irrespective of their experience with hoarding cases. About 90% of participants in both samples thought the criteria would be very/somewhat acceptable for professionals and sufferers. Most experts (70%) supported the inclusion of HD in the main manual, whereas only 50% of the APA members did. CONCLUSIONS The proposed criteria for HD have high sensitivity and specificity. The criteria are also deemed acceptable for professionals and sufferers alike. Training of professionals and the development and validation of semi-structured diagnostic instruments should improve diagnostic accuracy even further. A field trial is now needed to confirm these encouraging findings with real patients in real clinical settings.

Abstract
The objectives of this study were first to show adrenocortical response to a long-acting adrenocorticotropic hormone preparation (tetracosactide acetate zinc suspension) (ACTH-Z) and its effect on adrenocortical function in beef cows (Experiment 1) and second to apply the ACTH-Z challenge in dairy cows based on cortisol concentrations in milk collected at routine milking (Experiment 2). In Experiment 1, four beef cows in luteal phase were challenged with ACTH-Z, and plasma cortisol concentrations were determined for 48 h after the injection at 30-min to 2-h intervals. A rapid ACTH test was conducted 3 days before and 2 h after the completion of ACTH-Z injection for 48 h to investigate the effect on adrenocortical function. Plasma cortisol concentrations increased significantly 30 min after ACTH-Z injection (p < 0.001), and the high cortisol levels were maintained for approximately 10 h after the injection. In Experiment 2, eight dairy cows were subjected to ACTH-Z challenge 1-2 weeks and 4-5 weeks post-partum. Blood and milk samples were taken at morning and afternoon milking. All the cows showed a significant increase in cortisol concentrations in plasma as well as in skim milk 8 h after ACTH-Z injection 1-2 weeks and 4-5 weeks post-partum (p < 0.001). There was a significant correlation between plasma and skim milk cortisol concentrations 8 h after ACTH-Z challenge (r = 0.74, p < 0.001). The results obtained in this study suggest that elevated levels of plasma cortisol are maintained for approximately 10 h after ACTH-Z treatment without adverse effect on adrenocortical function and a long-acting ACTH-Z challenge based on cortisol concentrations in milk, which were collected at the morning and the afternoon milking, can be a useful tool to monitor adrenocortical function in cows.

Abstract
Oestrus detection error and conception rates after AI based only on secondary oestrus signs were evaluated in a high yielding, 24-h tie-stalled dairy herd with low fertility, using milk progesterone profiles. Oestrus detection was based on the secondary oestrus signs such as restlessness, swelling, congestion of vulva and clear mucus discharge. Sixty eight AI conducted after observing the secondary oestrus signs in 44 animals were included in the study. Of the 68 AI, 53 (77.9%) were conducted in the follicular phase, and 13 (19.1%) and 2 (2.9%) were carried out in the luteal phase and during pregnancy, respectively. The overall error in oestrus detection based on milk progesterone profiles was 22.1%. The oestrus detection error did not differ significantly among different secondary oestrus signs. None of the AI conducted in the luteal phase resulted in conception, whereas 20.8% of AI conducted in the follicular phase resulted in conception. No significant difference in the conception rates among the groups of cows with different secondary oestrus signs was shown. The high incidence of oestrus detection error in this study might have been caused by the detection of cows in oestrus based only on secondary oestrus signs due to the confinement of animals. In conclusion, there was a high incidence of heat detection error in the 24-h tie-stalled dairy herd and oestrus detection based only on secondary oestrus signs resulted in low conception rate.

Abstract
We report on the first spectroscopic study of the N=22 nucleus 32Ne at the newly completed RIKEN Radioactive Ion Beam Factory. A single gamma-ray line with an energy of 722(9) keV was observed in both inelastic scattering of a 226 MeV/u 32Ne beam on a carbon target and proton removal from 33Na at 245 MeV/u. This transition is assigned to the deexcitation of the first Jpi=2+ state in 32Ne to the 0+ ground state. Interpreted through comparison with state-of-the-art shell-model calculations, the low excitation energy demonstrates that the "island of inversion" extends to at least N=22 for the Ne isotopes.

Abstract
e22211 Background: Preoperative chemoradiotherapy (CRT) in lower rectal cancer is used to prevent from local recurrence and preserve anus by avoiding to rectal amputation. We have reported 17 micro DNAs and micro RNAs can predict effect of CRT in ASCO-GI 2009. In this study we aimed to predict side effect of CRT such as diarrhea using micro RNA2. present 16 micro RNA to predict side effect of CRT. Methods: Rectal cancer patients (n=22) who underwent preoperative CRT (40Gy radiotherapy combined with S- 1) were studied. S-1 is a novel oral fluoropyrimidine inhibitory for dihydropyrimidine dehydrogenase and has potent radiosensitizing property. RNA harvested from biopsy specimens of rectal cancer before preoperative CRT was hybridized to miRNA microarrays (821 genes). Side effect of CRT was evaluated by NCI-CTC. Groups were classified as side effect group (grade 3 or over) or non side effect group (group 0, 1, 2), respectively. Results: Fifteen patients had well differentiated adenocarcinoma and 7 patients had poorly differentiated adenocarcinoma. Before CRT, 3 patients are stage I, 1 patient is stage IIA, 7 patients are stage IIIB, 8 patients are stage lllC, 3 patients are stage lV in TMN classification. After CRT, 14 patients had PR (RR 63.6%) in RECIST and 15 patient had down staging in TMN classification. Four patients had side effect. One patient had diarrhea and cytopenia, 2 patients had diarrhea, 1 patient had dermatitis. All of them were grade 3. Sixteen miRNAs(micro RNA23a, 27a, 142–3p, 142–5p, 155, 185, 196a, 221, 223, 224, 374a, 374b, 376a, 378, 424, 452) were significantly lower expressed in side effect group than no side effect group. Conclusions: Sixteen micro RNAs were down-regulated in side effect group. Therefore, profile of micro RNA expression may predict the side effect of CRT. No significant financial relationships to disclose.
