Abstract
Atypical teratoid/rhabdoid tumor (AT/RT) is a rare aggressive central nervous system tumor that typically affects children under three years old and has poor survival with a high risk for neurologic deficits. The primary purpose of this study was to successfully treat the disease and delay or avoid whole-brain radiotherapy for children with AT/RT. A retrospective analysis was performed for six children diagnosed with AT/RT and treated with multimodal treatment at a single institute between 2014 and 2020. Furthermore, germline SMARCB1 aberrations and MGMT methylation status of the tumors were analyzed. One patient who did not receive a modified IRS-III regimen replaced with ifosphamide, carboplatin, and etoposide (ICE) in induction chemotherapy was excluded from this analysis. Five patients who received ICE therapy were under three years old. After a surgical approach, they received intensive chemotherapy and high-dose chemotherapy with autologous peripheral blood stem cell transplantation (HDCT/autoPBSCT) followed by intrathecal topotecan maintenance therapy. Three patients underwent single HDCT/autoPBSCT, and the other two received sequential treatment. Two patients with germline SMARCB1 aberrations and metastases died of progressive AT/RT or therapy-related malignancy, while 3 with localized tumors without germline SMARCB1 aberrations remained alive. One survivor received local radiotherapy only, while the other two did not undergo radiotherapy. All three surviving patients were able to avoid whole-brain radiotherapy. Our results suggest that AT/RT patients with localized tumors without germline SMARCB1 aberrations can be rescued with multimodal therapy, including induction therapy containing ICE followed by HDCT/autoPBSCT and intrathecal topotecan maintenance therapy without radiotherapy. Further large-scale studies are necessary to confirm this hypothesis.

Abstract
A 12-year-old girl developed Philadelphia chromosome-positive acute myeloid leukemia due to therapy-related myelodysplastic syndrome with monosomy 7 following neuroblastoma treatment. She underwent allogenic bone marrow transplantation from a human leukocyte antigens-DR1 locus-mismatched unrelated donor. However, on day 49 post transplantation, she presented with diarrhea due to gastrointestinal acute graft-versus-host disease (aGVHD), and treatments with prednisolone, budesonide rectal foam, and human mesenchymal stem cells were ineffective. Therefore, vedolizumab was administered from day 100, which improved the symptoms from gut stage 3 to gut stage 1. Consequently, prednisolone was withdrawn without any serious adverse effects. However, the symptoms worsened to gut stage 3 again; therefore, ruxolitinib was administered to achieve complete remission. Vedolizumab exhibits gut-selective action without systemic immunosuppressive activity. Hence, vedolizumab administration before other systemic immunosuppressive agents may be recommended in patients with steroid-refractory gastrointestinal aGVHD. Thus far, only a few reports have been published regarding the administration of vedolizumab and ruxolitinib for steroid-refractory gastrointestinal aGVHD in children. Further evidence should be obtained from patients treated with vedolizumab and ruxolitinib to confirm their effectiveness for pediatric steroid-refractory gastrointestinal aGVHD.

Abstract
Immunosuppressive therapy (IST) is the first-line treatment for patients with aplastic anemia (AA) who require blood transfusion when a human leukocyte antigen-matched related donor is unavailable. However, the proportion of patients with AA who are refractory to IST remains high (30%). IST in combination with eltrombopag has been studied in adults, but its efficacy and safety in children have not been established. We present three cases of AA that were initially refractory to IST but improved with additional eltrombopag administration. These patients were successfully managed using this strategy without the use of hematopoietic cell transplantation (HCT). The first patient achieved a complete response within one month after receiving eltrombopag. When the second and third patients were given eltrombopag, they were able to safely reduce the amount of cyclosporin they were given. They avoided blood transfusions, but no measurable response was obtained. The conjunctival icterus was detected and treated using a dose reduction of eltrombopag. Eltrombopag may be effective in children with AA who are refractory to IST, allowing them to avoid blood transfusions and HCT. More cases treated with this strategy are needed to confirm its efficacy and safety for children with AA.

Abstract
Diverse metabolic changes are induced by various driver oncogenes during the onset and progression of leukemia. By upregulating glycolysis, cancer cells acquire a proliferative advantage over normal hematopoietic cells; in addition, these changes in energy metabolism contribute to anticancer drug resistance. Because leukemia cells proliferate by consuming glucose as an energy source, an alternative nutrient source is essential when glucose levels in bone marrow are insufficient. We profiled sugar metabolism in leukemia cells and found that mannose is an energy source for glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Leukemia cells express high levels of phosphomannose isomerase (PMI), which mobilizes mannose to glycolysis; consequently, even mannose in the blood can be used as an energy source for glycolysis. Conversely, suppression of PMI expression or a mannose load exceeding the processing capacity of PMI inhibited transcription of genes related to mitochondrial metabolism and the TCA cycle, therefore suppressing the growth of leukemia cells. High PMI expression was also a poor prognostic factor for acute myeloid leukemia. Our findings reveal a new mechanism for glucose starvation resistance in leukemia. Furthermore, the combination of PMI suppression and mannose loading has potential as a novel treatment for driver oncogene-independent leukemia.

Abstract
The outcomes for relapsed and metastatic Ewing sarcoma (EWS) is extremely poor. Therefore, it is important to identify the tumor‐specific targets in these intractable diseases. High focal adhesion kinase (FAK) transcript expression levels in EWS cell lines are known. TAE226 is a dual inhibitor of FAK and insulin‐like growth factor‐I receptor (IGF‐IR), while PF‐562,271 is a dual inhibitor of FAK and proline‐rich tyrosine kinase 2. We compared the cytotoxicity of TAE226 and PF‐562,271 toward three EWS cell lines. TAE226 strongly inhibited proliferation of three cell lines when compared with PF‐562,271. Furthermore, we investigated the efficacy of TAE226 as well as its mechanism of action against EWS. A stable EWS cell line with FAK and IGF‐IR knocked down was established, and microarray analysis revealed dysregulated expression in various pathways. TAE226 treatment of EWS cell lines induced cell cycle arrest, apoptosis, AKT dephosphorylation, and inhibition of invasion. We demonstrated that TAE226 drastically inhibits the local growth of primary tumors and metastasis in EWS using mouse models. Furthermore, the combination of TAE226 and conventional chemotherapy proved to exert synergistic effects. TAE226 may be a candidate single agent or combined therapy drug to be developed for patients who have relapse and metastatic EWS tumors in future.

Abstract
Metabolic reprogramming of leukemia cells is important for survival, proliferation, and drug resistance under conditions of metabolic stress in the bone marrow. Deregulation of cellular metabolism, leading to development of leukemia, occurs through abnormally high expression of transcription factors such as MYC and Ecotropic Virus Integration site 1 protein homolog (EVI1). Overexpression of EVI1 in adults and children with mixed lineage leukemia-rearrangement acute myeloid leukemia (MLL-r AML) has a very poor prognosis. To identify a metabolic inhibitor for EVI1-induced metabolic reprogramming in MLL-r AML, we used an XFp extracellular flux analyzer to examine metabolic changes during leukemia development in mouse models of AML expressing MLL-AF9 and Evi1 (Evi1/MF9). Oxidative phosphorylation (OXPHOS) in Evi1/MF9 AML cells accelerated prior to activation of glycolysis, with a higher dependency on glutamine as an energy source. Furthermore, EVI1 played a role in glycolysis as well as driving production of metabolites in the tricarboxylic acid cycle. L-asparaginase (L-asp) exacerbated growth inhibition induced by glutamine starvation and suppressed OXPHOS and proliferation of Evi1/MF9 both in vitro and in vivo; high sensitivity to L-asp was caused by low expression of asparagine synthetase (ASNS) and L-asp-induced suppression of glutamine metabolism. In addition, samples from patients with EVI1+MF9 showed low ASNS expression, suggesting that it is a sensitive marker of L-asp treatment. Clarification of metabolic reprogramming in EVI1+ leukemia cells may aid development of treatments for EVI1+MF9 refractory leukemia.

Abstract
Here, we report the case of a 9-year-old girl with acute myeloid leukemia (AML) developed from systemic mastocytosis (SM). She experienced bladder and rectal disturbance due to an extramedullary nodule in the paraspinal region of the sacrum. Cytogenetic and genetic analyses of leukemic cells revealed the KIT D816Y mutation besides t (8;21) (q22:q22) /RUNX1-RUNX1T1. Despite receiving proton beam therapy after conventional chemotherapy, the patient relapsed after 2 months. As SM-AML with the KIT D816 mutation in adults exhibits a poor prognosis, hematopoietic stem cell transplantation is recommended. Owing to a few reports of SM-AML in children, the standard therapy for pediatric cases has not been established to date. Based on our experience and the related literature, the prognosis of childhood SM-AML could be as poor as in adults. Hence, further investigation, including mutational analyses of the KIT gene, is warranted to establish a risk-oriented strategy for managing childhood SM-AML.

Biopsy results suggested alveolar rhabdomyosarcoma bearing a methylated O6-methylguanine-DNA methyltransferase (MGMT) gene promoter. Serum microRNA-206 levels were elevated and remained high after three cycles of vincristine, dactinomycin, and cyclophosphamide (VAC). Replacement of vincristine, irinotecan, and temozolomide (VIT) for VAC induced a marked tumor reduction and normalization of the miR-206 levels. The patient completed 14 cycles of VIT with local radiotherapy and has been in remission for 31 months. Temozolomide could be effective for tumors with a methylated MGMT gene promoter. Individualized therapy is warranted for such patients.

Abstract
Inversion of chromosome 16 [inv(16)] has a good prognosis in acute myeloid leukemia (AML), but additional genetic aberrations influence the outcome. We herein describe the case of a 15-year-old Japanese boy with inv(16) harboring a low-allelic burden internal tandem duplication of FLT3 (FLT3-ITD) and KIT mutations. Conventional chemotherapy eradicated a clone with a low-allelic burden FLT3-ITD mutation, although another clone with a KIT mutation occurred 17 months later. Further investigation is necessary to identify AML with inv(16) conferring poor prognosis, to facilitate appropriate treatment with additional drugs, such as dasatinib or gemtuzumab ozogamicin.

Abstract
BACKGROUND/OBJECTIVES Most of the studies that have investigated the association between coffee consumption and hepatic steatosis have been experimental and small-scale clinical studies. As a result, epidemiological studies are scarce. To clear the association, we conducted a cross-sectional study and investigated the effects of coffee consumption with those of green tea consumption. SUBJECTS/METHODS We analyzed 1024 Japanese male workers. The diagnosis of hepatic steatosis was based on ultrasonography. We divided coffee and green tea consumption into the following three categories: non-drinker; 1-2 cups/day and ⩾3 cups/day. To investigate the association between hepatic steatosis and coffee or green tea consumption, we calculated the odds ratio (OR) and adjusted the means of leptin levels on each severity of hepatic steatosis. RESULTS A total of 265 of our subjects (25.9%) were diagnosed with hepatic steatosis. The ORs of the group of subjects who drank >3 cups of coffee/day was significantly lower compared with that of the noncoffee drinker group (OR 0.59, 95% confidence intervals 0.38-0.90, P=0.03). Although there was a significant difference between coffee consumption and leptin level only in the asymptomatic group, we found a decreasing trend in the asymptomatic and moderate-severe hepatic steatosis group. We did not find the same relationships in green tea consumption. CONCLUSIONS Although we did not find an association between hepatic steatosis and green tea consumption, coffee may have beneficial effects on hepatic steatosis. In addition, we produced one possible hypothesis that coffee consumption negatively associates with leptin levels in hepatic steatosis.

Abstract
We describe a 6-month-old infant with classic medulloblastoma. Gross total resection of the left cerebellar tumor was performed; however, relapse occurred during the administration of intrathecal and intravenous methotrexate-based chemotherapy. After undergoing resection, high-dose chemotherapy was administered consisting of topotecan, melphalan, and cyclophosphamide with autologous peripheral stem cell rescue followed by local irradiation and intrathecal topotecan, which resulted in a complete response for more than two years. The administration of high-dose chemotherapy followed by intrathecal topotecan as maintenance therapy is an effective strategy, without losses in the cognitive function, for avoiding the use of whole-brain irradiation for infantile classic medulloblastoma.

Abstract
We here report a 2-year-old female with relapsed acute myeloid leukemia (AML) with MLL gene rearrangement in the bone marrow and central nervous system. The 3'-RACE (Rapid Amplification of cDNA Ends) method identified the MLLT10 gene as a fusion partner of the MLL gene. The patient was complicated with hemophagocytic lymphohistiocytosis (HLH) and invasive aspergillosis (IPA) after re-induction treatment with FLAG-IDA following etoposide, cytarabine, and mitoxantrone. Although treatment with systemic anti-fungal drugs was effective for IPA, HLH did not improve. We considered tumor-associated HLH to be initiated from leukemic stem cells (LSCs) in the bone marrow niche because reverse transcription-polymerase chain reaction (RT-PCR) analysis of a bone marrow biopsy sample was positive for MLL-MLLT10. Gemtuzumab ozogamicin and sorafenib had no major effect on acquiring complete remission, and the patient died of progressive AML with an exacerbation of HLH and aspergillosis. LSCs are known to be resistant to conventional chemotherapy due to their quiescence in the cell cycle. Novel therapeutic concepts are important to eradicate LSCs in order to cure AML patients.

Abstract
We describe a 5-year-old female with acute lymphoblastic leukemia (ALL) who suffered from cytomegalovirus (CMV) retinitis during maintenance therapy consisting of 6-mercaptopurine (6-MP) and methotrexate (MTX) with pulses of vincristine (VCR) and dexamethasone (DEX). Administration of anticytomegaloviral drugs led to a complete regression of active retinitis. Her low CD4 positive T cells and serum immunoglobulin G (IgG) recovered when maintenance therapy was resumed without VCR and DEX. The patient has been in complete remission (CR) for more than 5 months after completion of maintenance therapy without recurrence of CMV retinitis.

Abstract
A Globosus amorphus along with a living calf was encountered following the transfer of blastocysts obtained by in vitro fertilization of in vitro-matured follicular oocytes in Japanese black cattle. Two embryos obtained 9 days after in vitro fertilization developed into either a hatched blastocyst with distinct inner cell mass or an expanded blastocyst with indistinct inner cell mass. The embryos were loaded into a 0.25-ml plastic straw and were nonsurgically transferred to the uterus of a heifer on Day 8 (Day 0 = estrus). On Day 75, a twin pregnancy was ultrasonically diagnosed in the right uterine horn, in which a live fetus with distinct limbs and a concomitant ovoid mass were detected. On Day 287, the dam developed parturient paralysis with dropsy of the fetal membranes. By palpation per rectum an ovoid mass was detected in the body of the uterus [corpus uteri] and a larger live fetus was in the uterine horn. A cesarean section was performed to extract a live fetus and a Globosus amorphus. The live fetus was female with the 60, XX female complements.

Abstract
Anaplastic lymphoma kinase (ALK) positive anaplastic large cell lymphoma (ALCL) is usually associated with a favorable prognosis. We describe an 11-year-old girl patient with ALK positive ALCL bearing t(2;5)(p23;q35) and t(8;17)(q24;q25) translocations who had an aggressive clinical course despite various combinations of intensive chemotherapy. Southern blot analysis identified C-MYC rearrangement. Immunohistochemistry and Northern and Western blot analyses revealed cmyc overexpression. A new fusion between ALO17 (ALK lymphoma oligomerization partner on chromosome 17) and C-MYC was identified by the 50-rapid amplification of cDNA ends. This new fusion may have possibly provoked the poor prognosis in this patient with ALK positive ALCL, and C-MYC rearrangement may indicate poor prognosis in ALCL.

Abstract
A serious decline in the reproductive performance of dairy cows occurs in southern Japan in the summer period, when the total number of hot days ≥35°C numbers more than 20 days annually. Previous reports have mentioned the effectiveness of embryo transfer (ET) at 7 days after AI (AI/ET) under heat-stressed conditions. In the present study, we investigated the effect of AI/ET on conception rate (CR) under heat-stressed conditions in the summer period. Artificial insemination was performed at 13 commercial dairies in this study from August through September in 2007 and 2008. Seven days after AI, a single embryo was transferred into the uterine horn contralateral to the ovary with a corpus luteum (AI/ET, n = 82). Artificial insemination at oestrus without further treatment was assigned as the control group (AI, n = 367). In 2007, frozen–thawed embryos of Japanese Black cattle were transferred, and the same cattle were used for ET of fresh embryos in 2008. The temperature-humidity index [0.8 × temperature + 0.01 ×relative humidity (temperature –14.4) + 46.4], rectal temperature, and diurnal highest or lowest and average ambient temperatures were measured at the time of AI and ET. Cows were diagnosed for pregnancy at 42 days after AI by palpation per rectum and were reexamined by transrectal ultrasonography at 60 days after AI. The CR was calculated as the number of cows diagnosed as pregnant 60 days after AI divided by the number of cows inseminated. Fetal loss was calculated as the number of cows that did not deliver calves after term divided by the number of cows diagnosed as pregnant. The CR, number of AI, fetal loss, and type of newborn (Holsteins, AI origin; Japanese Black, ET origin) were confirmed retrospectively. For statistical analysis, Fisher’s exact test and Student’s t-test were used for comparison of the CR, fetal loss, and body temperature by using a statistical software program for PC (Excel Statistics 2006). The CR for AI/ET was 30.4% and for AI was 13.8% in 2007 (P < 0.01), and the CR for AI/ET was 30.8% and for AI was 21.5% in 2008 (P = 0.294). The average diurnal temperature was 31.1°C in 2007 and 30.1°C in 2008, and the temperature-humidity index was 81.8 and 80.8, respectively. On Day 8, the pregnant cows had a lower rectal temperature than the open cows in 2007, but not in 2008 (38.9 v. 39.4°C in 2007; P < 0.05; and 39.1 v. 38.9°C in 2008; P > 0.05). The fetal loss was 38.1% in AI/ET v. 7.4% in AI in 2007 (P < 0.05) and 12.5% v. 0% in 2008 (P < 0.05), respectively. The AI/ET procedure could improve CR in dairy cows during the summer period in southern Japan. However, other problems may accompany AI/ET, such as higher fetal losses.

Abstract
Abstract
GP88 (progranulin) is an 88-kDa glycoprotein autocrine growth factor that plays a critical role in breast tumorigenesis. GP88 is expressed in human BC tumors in a positive correlation with their tumorigenicity. In estrogen receptor positive (ER+) cells, GP88 expression is low and is stimulated by estradiol whereas in ER negative (ER-) cells, it is constitutively overexpressed. In ER+ cells, increased GP88 expression was found to be associated with resistance to anti-estrogen therapy. In Her-2 overexpressing breast tumors, increased GP88 expression was associated with Herceptin resistance. Inhibition of GP88 expression in human breast adenocarcinoma cells resulted in a drastic reduction of tumor incidence and tumor growth in nude mice. Immunohistochemical studies carried out with 206 paraffin-embedded human breast biopsies have shown that GP88 is expressed in invasive ductal carcinomas in correlation with expression of markers of poor prognosis whereas normal tissues and benign breast lesions were negative. Importantly, high GP88 expression in tissue biopsies was accompanied by decreased disease-free and overall survival. Since GP88 contains a signal peptide for secretion, we have shown that GP88 can be found in serum. An IRB approve blood sampling study of 189 patients (Race: Caucasian- 91, African American-92, Asian-6; median age- 51 with a range from 26 to 81) established at the University of Maryland demonstrated that GP88 was measurable in serum and that GP88 serum level was statistically elevated in breast cancer patients when compared to healthy individuals. Median level of GP88 was 40.7 ng/ml (range 6.4-80) in early stage (stage 1 –3) BC pts (p- value = 0.007) and 45.3 ng/ml (range 9.8 to 158.4) in stage 4 metastatic BC patients (p-value= 0.0007). Statistically significant increase in circulating GP88 level was found in early stages as well as in metastatic disease when compared to healthy individuals.Since we have shown that GP88 tissue expression was associated with increased disease recurrence, the present study was focused on examining whether GP88 serum level was also increased in disease progression and could be used to monitor disease recurrence. Our data show that patients with disease recurrence or progression presented a 5 to 10 fold increase in their GP88 serum levels.This study identifies GP88 as a measurable biomarker for recurrence or disease progression not only at the tissue but also at the serum level.This study is supported by grants from MIPS, the Avon Foundation and from the National Cancer Institute.

Abstract
We describe an infant with cytomegalovirus (CMV) infection presenting as transient myeloproliferation resembling juvenile myelomonocytic leukemia (JMML). The patient fulfilled the international diagnostic criteria of JMML, including hypersensitivity to granulocyte-macrophage colony-stimulating factor (GM-CSF). Viral studies using serologic assays and polymerase chain reaction (PCR) were positive for CMV. Clinical symptoms disappeared and laboratory values returned to normal without specific treatment within 1 year. Follow-up showing a decrease in viral titers suggested CMV infection as an etiologic factor for the development of myeloproliferative features. We conclude that the CMV infection transiently induced abnormal myelopoiesis in this infant.

Abstract
Holstein cows received, subcutaneously a non-degradable implant containing 5mg of the GnRH agonist Deslorelin (DESL) or no implant (CON) at 2+/-1 days postpartum (dpp). All cows were injected with PGF(2alpha) at 9 dpp. Previous pregnant (PPH) and non-pregnant uterine horns (PNPH) were determined by palpation per rectum. In Experiment 1, cows [DESL implant (n=10) and CON (n=9)] were examined by ultrasonography to record ovarian structures (23, 30 and 37 dpp) and uterine horn and cervical diameters (16, 23, 30 and 37 dpp). Uterine tone was scored before ultrasonography. Vaginoscopy was conducted just after ultrasonography examination to assess cervical discharge and color of the external cervical os. Blood samples were collected on a weekly basis for hormonal analyses. In Experiment 2, cows [DESL implant (n=77) and CON (n=70)] were palpated per rectum and vaginoscopy at 30 dpp for scoring of uterine tone, uterine horns, cervical diameter, and discharge. Blood samples were collected only at 9 dpp. In Experiment 1, DESL-implant-treated cows had more Class 1 follicles (P<0.01), less Class 2 (P<0.01) and Class 3 follicles (P<0.01) and no corpus luteum (CL) formation (P<0.01). In CON cows, six of nine animals had visible CL at 25+/-7 dpp. At 9 dpp plasma concentration of E(2), P(4) (P<0.01) and PGFM (P<0.05) were less in the DESL-implant treatment group. Diameter of PPH (P<0.01), PNPH (P<0.01) and cervix (P=0.08) were less in the DESL-implant treatment associated with greater uterine tone (P=0.07). The DESL-implant cows had a greater frequency of clear cervical discharge (P=0.09) and pink cervical os (P=0.06). In Experiment 2, plasma concentrations of PGFM were less at 9 dpp in DESL-implant treatment (P<0.01). Diameters of the PPH (P<0.01) and PNPH (P<0.01) were less and more uterine tone (P<0.01) in the DESL-implant treatment. Diameter of cervix and frequency of a cervical discharge score did not differ between treatments. Treatment with non-degradable Deslorelin (5mg) implant during postpartum: (1) suppressed ovarian follicular development, (2) enhanced physical involution of the uterus and cervix, (3) increased tone of the uterine wall, (4) decreased frequency of purulent cervical discharges, and (5) reduced inflammatory processes of the reproductive tract.

Abstract
Two Holstein heifers and a cow were diagnosed with White Heifer Disease by ultrasonography. Case 1 was a 14 month-old heifer with aplasia of both sides of the uterine horn. In case 2, a primiparous cow and case 3, an 18 month-old heifer, both showed aplasia of the right uterine horn. Case 2 became pregnant by artificial insemination at ipsilateral ovulatory follicle and corpus luteum in the left ovary, while case 3 became pregnant by embryo transfer at 7 days after oestrus with contralateral corpus luteum in the right ovary.

Abstract
An 8-month-old Japanese Black heifer with severe erythropoietic symptoms was subjected to clinical, histological and cytological examinations. During the 1 month clinical observation period, severe increases in RBC count, packed cell volume and haemoglobin concentration were observed. The plasma erythropoietin (Epo) concentration of the heifer (20.7 mIU/ml) was similar to that observed in normal control heifers. Blood gas examinations of the arterial and venous blood revealed low levels of partial pressure O(2) (PaO(2)), partial pressure CO(2) (PaCO(2)) and O(2) saturation (SaO(2)), while the blood pH was within the normal range. Gross lesions could not be detected. However, microscopic observation revealed severe proliferation of erythroblasts in the bone marrow and in the spleen without evidence of neoplastic changes. Based on these clinical and pathological examinations, we diagnosed the heifer as being the first case of primary erythrocytosis in Japanese Black cattle.

Abstract
Embryonic and fetal mortality reduce reproductive performance of lactating dairy cows. The objectives of this study were to reduce pregnancy loss by administering a deslorelin implant (GnRH agonist) during the late embryonic period, to reduce follicular growth, induce accessory corpora lutea, and increase plasma progesterone concentrations. Lactating dairy cows received an implant containing 2.1 mg of deslorelin (Deslorelin group; n = 89) or no treatment (Control group; n = 92) on Day 27 of pregnancy. Pregnancy, ovarian structures and plasma progesterone concentrations were determined on Days 27 and 45, and pregnancy was re-confirmed on Day 90. On Day 45, mean +/- S.E.M. numbers of class 2 (6-9 mm; 0.72+/-0.19) and class 3 (> or = 10 mm; 0.86 +/- 0.12) follicles for cows in the Deslorelin group were lower (P < 0.01) than the numbers of class 2 (1.90 +/- 0.18) and class 3 (1.92 +/- 0.12) follicles for cows in the Control group. On Day 45, the number of accessory corpora lutea for cows in the Deslorelin group (1.80 +/- 0.07) were greater (P < 0.01) than for cows in the Control group (1.31 +/- 0.07). On Day 45, plasma progesterone concentration was increased (P < 0.01) for cows in the Deslorelin group (8.03 +/- 0.33 ng/mL) compared to cows in the Control group (6.40 +/- 0.31 ng/mL). Pregnancy losses did not differ between Days 27 and 45 and Days 45 and 90 for cows in the Control (15.2 and 11.0%, respectively) and Deslorelin groups (20.2 and 10.5%, respectively). However, in the Deslorelin group, pregnancy loss between Days 45 and 90 was lower (P < 0.05) for cows that formed an accessory CL (0%) compared to cows that did not form an accessory CL (16.1%).

Abstract
The objective was to compare pregnancy rates and pregnancy losses in lactating dairy cows that were diagnosed not pregnant and re-inseminated following either the Ovsynch or Heatsynch protocols. Also evaluated were the effects of stages of the estrous cycle, ovarian cysts and anestrus on pregnancy rates for both treatments. Non-pregnant cows (n = 332) as determined by ultrasonography on day 27 post-AI (study day 0) were divided into two groups. Cows in the Ovsynch group (n = 166) received GnRH on day 0, PGF2alpha on day 7, GnRH on day 9, and timed AI (TAI) 16 h later (day 10). Cows in the Heatsynch group (n = 166) received GnRH on day 0, PGF2alpha on day 7, estradiol cypionate (ECP) on day 8, and TAI 48 h later (day 10). Cows detected in estrus on days 8 and 9 were inseminated and included in the study. On day 0, cows were classified according to different stages of the estrous cycle, or presence of ovarian cysts or anestrus. Pregnancy rates were evaluated 27, 45 and 90 days after resynchronized AI. Overall, there was no difference in pregnancy rates on days 27, 45 and 90 between cows in the Ovsynch (25.2, 17.5, and 13.9%) and Heatsynch (25.8, 19.9, and 16.1%) groups. There was no difference in pregnancy losses from days 27 to 45 and days 45 to 90 for cows in the Ovsynch (25.0 and 17.9%) and Heatsynch (14.7 and 10.3%) groups. However, pregnancy rates were increased when cows in metestrus were subjected to the Heatsynch protocol and cows with ovarian cysts were subjected to the Ovsynch protocol.

Abstract
The objective was to evaluate the effects of pregnancy and bovine somatotropin (bST) on endometrial gene and protein expression related to maintenance of pregnancy in nonlactating dairy cows at d 17. In endometrial tissues, treatment with bST increased the steady state concentration of oxytocin receptor (OTR) mRNA; bST-treated cyclic (bST-C) cows had greater OTR mRNA than bST-treated pregnant (bST-P) cows. Estradiol receptor alpha (ERalpha) mRNA was reduced in bST-P cows compared with control P and C (no bST) cows. Western blotting revealed that pregnancy decreased the abundance of ERalpha protein, and bST stimulated an increase in ERalpha protein in C and P cows. Treatment with bST increased steady state concentrations of progesterone receptor (PR) mRNA. No differences were detected in steady state mRNA concentrations of prostaglandin H synthase-2 (PGHS-2), prostaglandin E synthase, and prostaglandin F synthase due to pregnancy or bST treatment. However, PGHS-2 protein was increased in response to pregnancy and bST treatment. Immunostaining indicated that P decreased ERalpha protein in luminal epithelium and increased PR protein in epithelial cells of the uterine glands. The PR protein response in the glands was less in bST-P cows than in P cows. In the stromal layer of the endometrium, bST decreased PR protein abundance in C and P cows. The PGHS-2 protein was localized exclusively in the luminal epithelium cells of endometrium and was increased in P cows. In conclusion, distinctly different mRNA and protein responses were detected between C and P cows related to prostaglandin biosynthesis, and bST-induced changes may potentially impact mechanisms associated with maintenance of pregnancy in nonlactating cows.

Abstract
Nonlactating dairy cows were used to examine effects of bovine somatotropin (bST) on components of the insulin-like growth factor (IGF) system. Estrus was synchronized in cows with a Presynch + Ovsynch protocol and timed AI (TAI; n = 55) or not TAI (cycling, C; n = 23) on d 0 (time of synchronized ovulation). On d 0 and 11, cows received bST (500 mg) or no bST, and were sacrificed on d 17. Pregnancy rates were less in bST cows (27.2%, 9 of 33) than in controls (63.6%; 14 of 22). In contrast, conceptuses were larger in bST-treated cows (39.2 +/- 4.8 cm) than in controls (20 +/- 4.3 cm). Total interferon-tau in uterine luminal flushings (ULF) was greater in bST-treated cows (7.15 > 2.36 microg). Number of class 2 follicles (6 to 9 mm) was less in bST-C cows on d 7 and 16. On d 17, corpus luteum (CL) weight tended to be greater in bST-treated cows. Concentrations of progesterone were greater after d 10 in C than in pregnant (P) cows. In the ULF, IGF-binding protein-3 was greater in bST-P cows than in pregnant cows. A tendency for an increase in IGF-I hormone concentrations in the ULF was detected on d 17 in bST-treated and cyclic cows. Endometrial mRNA for IGF-I, IGF-II, IGFBP-2, and IGFBP-3 increased in bST-C, but not in bST-P cows. Treatment with bST increased plasma concentrations of insulin, IGF-I, and growth hormone (GH). In conclusion, bST may have hyperstimulated plasma IGF-I and insulin to cause asynchrony between conceptus and uterus that was detrimental to pregnancy.

Abstract
Evidence is presented that bovine somatotrophin (bST) treatment of lactating dairy cows enhances both expression of oviductal insulin-like growth factor II (IGF-II) mRNA and endometrial insulin-like growth factor binding protein 3 (IGFBP-3) mRNA between day 3 and day 7 of the oestrous cycle. mRNA encoding growth hormone (GH) receptor in endometrial tissues increased between day 3 and day 7 of the oestrous cycle. The changes induced by bST treatment may contribute to stimulation of embryo development and increase pregnancy rates in lactating dairy cows. Additive effects of bST and rb interferon tau (rbIFN-tau) to inhibit phorbol ester induction of prostaglandin F2alpha secretion in immortalized bovine endometrial cells indicates that there is interplay between their signal transduction pathways. Non-lactating dairy cows were killed at day 17 after oestrus to evaluate the effects of pregnancy status (cyclic versus pregnant) and bST (bST versus control) treatment on endometrial gene expression. Distinctly different mRNA and protein responses were detected between cyclic and pregnant cows that were related to luteolytic-antiluteolytic drive (that is expression of progesterone receptor, oxytocin receptor, oestradiol receptor alpha and prostaglandin GH synthase 2 (PGHS-2)). The bST-induced changes in PGHS-2 protein (+), oxytocin receptor mRNA (+) and oestrogen receptor alpha protein (+) may potentially affect the mechanisms associated with maintenance of pregnancy. Two experiments were conducted to evaluate whether ovarian follicular suppression induced by biodegradable deslorelin implants would reduce either early or late embryo losses. A 450 microg deslorelin implant used to induce ovulation in a timed insemination programme decreased subsequent follicular development and tended to reduce early embryo losses, whereas a 2.1 mg deslorelin implant failed to reduce late embryonic losses when inserted on day 27 of pregnancy.

Abstract
A 45-year-old woman with chronic hepatitis B underwent partial hepatectomy for hepatocellular carcinoma (HCC). However, the HCC recurred 2 months after surgery and rapid progression of the disease resulted in her death. Immunohistochemistry showed that transforming growth factor-alpha (TGFalpha) was barely expressed in the liver specimens obtained at hepatic resection, whereas autopsy specimens were strongly stained with anti-TGFalpha antibody in the cytoplasm of both non-tumourous and tumourous liver cells. A higher level of Ki67 expression, a proliferating marker, was observed in the recurrent HCC, similar to that of TGFalpha. Thus, we speculate that the partial hepatectomy increased the level of TGFalpha leading to recurrence and progression of HCC through an autocrine/paracrine mechanism.

Abstract
In mammals, sperm activity is known to be varied largely according to individuals though physiological reasons have not been clarified yet. In our previous study [Koyama S, Kamimura S. Lowered sperm motility in mice of subordinate social status. Physiol Behav 1999;65:665-669.], we showed that sperm motility was higher in the dominant mice than the subordinate mice, by which it was suggested that social factors could affect sperm activity in mammals. In the present study, we investigated how the observed influence of social dominance would be modified by the existence of females. From 5 to 15 weeks of age, male mice were pair housed and were kept under three different housing conditions: (1) with females; (2) with bedding soiled by females; and (3) control group. The social dominance of the paired males was determined by resident-intruder tests that were carried out from 8 to 15 weeks of age. At the end of 15 weeks of age, sperm activity, weights of organs, level of serum testosterone and corticosterone were determined. It was revealed that sperm density was higher and weight of preputial glands was heavier in dominants than in subordinates when they were kept with females or female bedding. In the subordinates, however, there were no differences among the three housing conditions; that is, there were no female effects on the subordinates. On the other hand, sperm motility was high in the dominants of control group, low in the subordinates, and lower in the dominants that were kept with females. The dominants of the males that were kept with females showed high aggressiveness, and there were negative correlationships to be seen between aggressiveness and sperm motility. It was suggested that: (1) Female odor promotes spermatogenesis of the dominants, but it does not promote that of the subordinates. (2) Sperm motility is more affected by social dominance than by female odor. (3) Excessive aggressiveness has negative influence on sperm motility.

Abstract
Retinoids are known to modulate macrophage differentiation, proliferation, and function including cytokine gene expression. However, signaling of retinoic acid (RA), a biologically active metabolite of vitamin A, in Kupffer cells has not been characterized. This study reports mRNA expression by rat Kupffer cells of RA receptor (RAR) and retinoid X receptor (RXR) subtypes and their binding activities to the RA responsive element (RARE) or retinoid X responsive element (RXRE). Total RNA and nuclear proteins were extracted from Kupffer cells immediately following isolation from livers of normal male Wistar rats. Competitive PCR demonstrated relative mRNA expression of RAR and RXR subtypes in the order of beta>alpha>gamma for and alpha>beta>gamma, respectively. It also demonstrated that the RXR alpha and beta mRNA levels were 5- to 10-fold higher in Kupffer cells than in hepatic stellate cells while RAR mRNA expression was shown to be similar for all the subtypes in both cell types. Gel mobility shift assays of nuclear extracts with labeled RARE and RXRE probes showed distinct binding activities for both responsive elements, which were effectively displaced with cold probes in excess but not with an unrelated oligonucleotide. A supershift assay with an antibody against RARalpha or RXRalpha has confirmed the contribution of both receptors to RARE binding and that of the RXRalpha to RXRE binding activity. These results represent the first demonstration of RA signaling at the nuclear level in Kupffer cells.

Abstract
Renin-producing tumors of extrarenal origin are rare in children. An 8-year-old boy with hepatoblastoma and hypertension associated with a high plasma renin level is reported. After chemotherapy, the plasma renin level normalized and the hypertension spontaneously resolved. The patient underwent surgery, and a right trisegmentectomy of the liver and a partial resection of the second and third segments were performed. The tumor was as shown the source of renin by immunohistochemical study and reverse transcriptase-polymerase chain reaction.

Abstract
Fragmented flagellar axonemes of sand dollar spermatozoa were reactivated by rapid photolysis of caged ATP. After a time lag of 10 ms, axonemes treated with protease started sliding disintegration. Axonemes without protease digestion started nanometer-scale high-frequency oscillation after a similar time lag. Force development in the sliding disintegration was measured with a flexible glass needle and its time course was corresponded well to that of the dynein-ADP intermediate production estimated using kinetic rates previously reported. However, with a high concentration ( approximately 80 microM) of vanadate, which binds to the dynein-ADP intermediate and forms a stable complex of dynein-ADP-vanadate, the time course of force development in sliding disintegration was not affected at all. In the case of high frequency oscillation, the time lag to start the oscillation, the initial amplitude, and the initial frequency were not affected by vanadate, though the oscillation once started was damped more quickly at higher concentrations of vanadate. These results suggest that during the initial turnover of ATP hydrolysis, force generation of dynein is not blocked by vanadate. A vanadate-insensitive dynein-ADP is postulated as a force-generating intermediate.

Abstract
It is well known that alcoholic liver disease is associated with iron overload. To study the role of hemochromatosis gene mutations on the pathogenesis of alcoholic liver disease (ALD), we have analyzed C282Y and H63D mutations on the chromosomes obtained from 95 Japanese alcoholics. Patients were divided in two groups [i.e., 64 alcoholic patients with liver damage (group I) and 31 alcoholics without liver damage (group II)]. In group I, biochemical examinations showed that serum levels of iron and ferritin were significantly high, and unsaturated iron binding capacity levels were low, compared with those of group II. An analysis by means of allele-specific polymerase chain reaction demonstrated that C282Y mutation was not observed in both groups I and II. H63D mutation was observed in only two heterozygotes of group I and in one heterozygote of group II. Results could not indicate the relationship between ALD and these mutations. We speculate that other causes of iron overload may exist in ALD with iron overload.

Abstract
The correlation between social status and sperm motility of mice was investigated. From 5 to 15 weeks of age, mice were kept under two housing conditions, i.e., in pairs or in isolation. The social dominance in the paired mice was determined with the resident-intruder tests, which were carried out from 8 to 15 weeks of age. At the end of 15 weeks of age, sperm activity, weights of reproductive organs, and serum testosterone were determined. It was revealed that the sperm motility of dominant mice was significantly higher than that of the subordinates. The sperm motility of the isolated mice was also significantly higher than the subordinates. It was suggested that the subordinate social status lowered sperm motility.

Abstract
One of the components of hemoglobin from the larval hemolyph of Tokunagayusurika akamusi possesses naturally occurring substitution at the E7 helical position (Leu E7) [M. Fukuda, T. Takagi, K. Shikama, Biochim. Biophys. Acta 1157 (1993) 185-191]. Its oxygen affinity is almost comparable to those of mammalian myoglobins and it exhibits Bohr effect. Both acidic and alkaline forms of the ferric hemoglobin have been investigated using 1H NMR in order to gain insight into molecular mechanisms for relatively high oxygen affinity and Bohr effect of this protein. The NMR data indicated that the acidic form of the protein possesses pentacoordinated heme, and that the alkaline form possessing OH- appears with increasing the pH value. pH titration yielded a pK value of 7.2 for the acid-alkaline transition, and this value is the lowest among the values reported so far for various myoglobins and hemoglobins. The kinetic measurements of the transition revealed that the activation energy for the dissociation of the Fe-bound OH-, as well as the dissociation and association rates, decrease with increasing the pH value. These pH dependence properties are likely to be related to the Bohr effect of this protein.

Abstract
To assess the relationship between insulin-like growth factor II (IGF2) and H19 gene expression at the cellular level, we have examined the distribution of IGF2 and H19 mRNA by means of an situ hybridization in hepatic malignancies consisting of hepatocellular carcinoma (HCC), cholangiocellular carcinoma (CCC), and metastatic liver cancer (MLC). In HCC, 15 of 27 tumors (56%) and 11 of 27 tumors (41%) demonstrated increased IGF2 and H19 gene expression, respectively. Of 16 HCCs with increased expression of either IGF2 or H19, 10 tumors coexpressed both transcripts at comparable levels. Moreover, the spatiotemporal distribution and the cellular localization of the two gene transcripts were almost identical, suggesting the presence of a reciprocal relation between IGF2 and H19. In addition, 5 HCCs showed increased IGF2 expression without concomitant H19 expression, whereas 1 HCC showed increased H19 expression without IGF2 transcripts. However, 11 HCCs showed no IGF2 or H19 expression. On the other hand, neither IGF2 transcripts nor H19 transcripts were detected in 2 CCCs or 10 MLCs studied. The data suggest that IGF2 and/or H19 gene expression may be characteristic of some HCCs.
