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
The study examined whether royal jelly (RJ) can prevent obesity and ameliorate
hyperglycemia in type 2 diabetes. This study utilized obese/diabetic KK-Ay mice. RJ (10
mg/kg) was administered by oral gavage. Body weight, plasma glucose and insulin levels
were measured. mRNA and protein levels were determined using quantitative reverse
transcription polymerase chain reaction and western blotting, respectively. Four weeks of
RJ administration improved hyperglycemia and partially suppressed body weight gain,
although the latter effect did not reach statistical significance. In addition, RJ
administration did not improve insulin resistance. RJ administration suppressed the mRNA
expression of glucose-6-phosphatase (G6Pase), a key enzyme of
gluconeogenesis, in the liver. Simultaneously, RJ administration induced adiponectin
(AdipoQ) expression in abdominal fat, adiponectin receptor-1
(AdipoR1) expression in the liver and phosphorylated AMP-activated
protein kinase (pAMPK) expression, which suppressed G6Pase levels in the livers of KK-Ay
mice. pAMPK levels were also increased in skeletal muscle, but glucose transporter-4
(Glut4) translocation was not increased in the RJ supplementation group. The improvement
in hyperglycemia due to long-term RJ administration may be because of the suppression of
G6Pase expression through the upregulation of AdipoQ and
AdipoR1 mRNA and pAMPK protein expressions.

Abstract
Type 2 diabetes is a polygenic disease and characterized by hyperglycemia and insulin
resistance, and it is strongly associated with obesity. However, the mechanism by which
obesity contributes to onset of type 2 diabetes is not well understood. We generated rat
strains with a hyperglycemic quantitative trait locus (QTL) derived from the Otsuka
Long-Evans Tokushima Fatty rat and a fa/fa
(Lepr–/–) locus derived from the Zucker Fatty rat.
Phenotypes for plasma glucose, and insulin levels were measured, and RNA and protein
levels were determined using reverse transcription quantitative PCR and Western blot
analyses, respectively. Compared with the obese control strain F344-fa
(Lepr–/–), plasma glucose levels of the obese
F344-fa-nidd6 (Lepr–/– and
Nidd6/of) significantly increased, and plasma insulin levels
significantly decreased. These phenotypes were not observed in the lean strains,
suggesting that the Nidd6/of locus harbors a diabetogenic gene associated
with obesity. We measured the expression of 41 genes in the Nidd6/of QTL
region of each strain and found that the mRNA expression levels of the two genes
significantly differed between the obese strains. The two genes, pleckstrin homology
domain-containing, family S member 1 (Plechs1) and peroxiredoxin III
(Prdx3), were differentially expressed only in the obese rats,
suggesting that these two genes are involved in the mild elevation of blood glucose levels
and insulin resistance in obesity.

Abstract
The mes rat is from an inbred mutant colony of rats with spontaneous eosinophilia. In order to investigate the pathogenesis of the mes rat, the histopathology and hematology for 76 mes rats were examined at several weeks of age. Tissue eosinophilia developed at 8 weeks of age when the blood eosinophil was 500 cells per microliter or more. Subsequently, eosinophilia progressed with age, and splenic eosinophilopoiesis and erythropoiesis appeared simultaneously. Many inflammatory lesions were induced after 10 weeks of age when the blood eosinophils became 1,000 cells per microliter or more. Gastroenteritis and mesenteric lymphadenitis were seen in 44 of 47 (94%) and 31 of 47 (66%) rats, respectively, after 10 weeks of age. Aortitis that deteriorated with age was found in 19 of 39 (49%) rats after 12 weeks of age. Hepatic fibrosis was found in four rats that exhibited severe eosinophilia and anemia. These results are comparable to the features of a hypereosinophilic syndrome in humans and other animals.

Abstract
Modified cyclodextrin sulphate (mCDS) in which lipophilic groups were introduced to cyclodextrin sulphate (CDS) was synthesized and proved more inhibitory to the replication of HIV-1 and HIV-2 than CDS or dextran sulphate (DS). The anti-coagulant activity of mCDS was lower than that of DS. Cyclodextrin phosphate (CDP) showed anti-HIV activity similar to that of CDS, and its anti-coagulant activity was even lower than that of mCDS. Flow cytometric analysis suggested that the mechanism of the anti-HIV-1 action of CDS, mCDS, and CDP is based on inhibition of HIV-1 binding to the cells. The peak blood concentration after oral administration of mCDS11(potassium tris[6-benzylthio-6-deoxy]-β-cyclodextrin hexadecasulphate) to rabbits was about 1000 times higher than the concentration showing anti-HIV activity. The retention time in the blood was also long (blood half-life: 4 h). These results point to the potential usefulness of oral mCDS administration in the prophylaxis and/or therapy of HIV infections.

Abstract
We evaluated the flow in experimental pig aneurysms using a high speed video system with tracer particles and digital subtraction angiography (DSA). We found that flow velocity in experimental aneurysms was fast on the inflow of aneurysms. There was a certain correlation between mean transit time (MTT) and velocity in experimental aneurysms. Therefore, the differences of flow velocity in aneurysms will be detected using DSA. The flow in aneurysms was much changed by platinum coil embolization.

Abstract
Flow studies are important to understanding pathogenesis and treatment of cerebral aneurysms, but have not been possible in the clinical setting. We used experimental aneurysms established in and then removed from pigs to compare and correlate flow studies by high-speed video photography of introduced particles and by clinically applicable digital subtraction angiography. Venous pouches were used to create aneurysms in incised common carotid arteries. After aneurysms and parent arteries were removed, specimens were rendered translucent with solvents so they could be studied by video photography of introduced plastic particles in addition to digital subtraction angiography with iodinated contrast material. Regions of interest were studied individually. Mean transit time for contrast in the preparation correlated with videographically measured particle flow velocity (r = 0.616). Digital subtraction angiography should be useful in evaluation of flow in the clinical assessment and treatment of cerebral aneurysms, such as in endovascular therapy.

Abstract
The Matsumoto Eosinophilic Shinshu (MES) rat originated from an inbred mutant colony of rats with spontaneous eosinophilia. As part of an investigation of the pathogenesis of the MES rat, we examined the haematology data for 106 males and 88 females and age-associated changes using an automated haematology analyser, flow cytometric analysis and morphological examination. The data at 10 weeks of age showed the MES rats had higher counts for eosinophils and neutrophils, slightly higher counts for lymphocytes, monocytes, basophils, and large unstained cells (LUCs), and slightly lower values for the erythrocytic parameters when compared with Sprague-Dawley (SD) rats. In data for MES rats aged 8 to 20 weeks, eosinophil counts increased with age up to 20 weeks together with some increased neutrophil counts. After 11 weeks of age, counts for lymphocytes, monocytes, basophils, and LUCs in the MES rats were also slightly increased. In female MES rats, flow cytometric analysis showed increased counts for pan-T+ cells, but blasts, abnormal granulocytes and lymphocytes were not detected morphologically. The MES rat characterized by the haematological findings could be a useful animal model for studies of hypereosinophilia.

Abstract
BACKGROUND Trials of salvage therapy for advanced urothelial carcinoma have required prior platinum-based therapy. This practice requires scrutiny because non-platinum-based first-line therapy may be offered to cisplatin-ineligible patients. PATIENTS AND METHODS Data of patients receiving salvage systemic chemotherapy were collected. Data on prior first-line platinum exposure were required in addition to treatment-free interval, hemoglobin, Eastern Cooperative Oncology Group performance status, albumin, and liver metastasis status. Cox proportional hazard regression was used to evaluate their association with overall survival (OS) after accounting for salvage single-agent or combination chemotherapy. RESULTS Data were obtained from 455 patients previously exposed to platinum-based therapy and 37 not exposed to platinum. In the group exposed to prior platinum therapy, salvage therapy consisted of a single-agent taxane (n = 184) or a taxane-containing combination chemotherapy (n = 271). In the group not exposed to prior platinum therapy, salvage therapy consisted of taxane or vinflunine (n = 20), 5-fluorouracil (n = 1), taxane-containing combination chemotherapy (n = 12), carboplatin-based combinations (n = 2), and cisplatin-based combinations (n = 2). The median OS for the prior platinum therapy group was 7.8 months (95% confidence interval, 7.0, 8.1), and for the group that had not received prior platinum therapy was 9.0 months (95% confidence interval, 6.0, 11.0; P = .50). In the multivariable analysis, prior platinum therapy versus no prior platinum exposure did not confer an independent impact on OS (hazard ratio, 1.10; 95% confidence interval, 0.75, 1.64; P = .62). CONCLUSION Prior platinum- versus non-platinum-based chemotherapy did not have a prognostic impact on OS after accounting for major prognostic factors in patients receiving salvage systemic chemotherapy for advanced urothelial carcinoma. Lack of prior platinum therapy should not disqualify patients from inclusion onto trials of salvage therapy.

Abstract
OBJECTIVE We investigated the effects of single or repetitive intra-articular injections of synovial mesenchymal stem cells (MSCs) on a rat osteoarthritis (OA) model, and elucidated the behaviors and underlying mechanisms of the stem cells after the injection. DESIGN One week after the transection of the anterior cruciate ligament (ACL) of wild type Lewis rats, one million synovial MSCs were injected into the knee joint every week. Cartilage degeneration was evaluated with safranin-o staining after the first injection. To analyze cell kinetics or MSC properties, luciferase, LacZ, and GFP expressing synovial MSCs were used. To confirm the role of MSCs, species-specific microarray and PCR analyses were performed using human synovial MSCs. RESULTS Histological analysis for femoral and tibial cartilage showed that a single injection was ineffective but weekly injections had significant chondroprotective effects for 12 weeks. Histological and flow-cytometric analyses of LacZ and GFP expressing synovial MSCs revealed that injected MSCs migrated mainly into the synovium and most of them retained their undifferentiated MSC properties though the migrated cells rapidly decreased. In vivo imaging analysis revealed that MSCs maintained in knees while weekly injection. Species-specific microarray and PCR analyses showed that the human mRNAs on day 1 for 21 genes increased over 50-fold, and increased the expressions of PRG-4, BMP-2, and BMP-6 genes encoding chondroprotective proteins, and TSG-6 encoding an anti-inflammatory one. CONCLUSION Not single but periodic injections of synovial MSCs maintained viable cells without losing their MSC properties in knees and inhibited osteoarthritis (OA) progression by secretion of trophic factors.

Abstract
BACKGROUND There have been no comparative studies of tacrolimus vs. anti-tumour necrosis factor (anti-TNF) agents to determine which treatment is safer or more effective in refractory ulcerative colitis (UC). AIM To compare short-term safety and efficacy of tacrolimus vs. anti-TNF agents for active UC. METHODS One hundred patients with moderate-to-severe active UC were studied. Fifty patients were treated with oral tacrolimus (TAC group). The other 50 patients were treated with anti-TNF agents (anti-TNF group): 40 with infliximab and 10 with adalimumab. Primary endpoints were clinical response and remission rates, colectomy rate, and the incidence of adverse events during 12 weeks. RESULTS The incidence of adverse events was 12% in the TAC vs. 18% in the anti-TNF groups (P = 0.58). At week 12, clinical remission rate was 40% in the TAC vs. 28% in the anti-TNF groups (P = 0.29). Clinical response (including remission) rate was 62% in the TAC vs. 64% in the anti-TNF groups (P > 0.99). Five patients (10%) in the TAC and 8 (16%) in the anti-TNF groups required colectomy (P = 0.55). In a subgroup analysis restricted to severely active UC, the response rate was 50% in the TAC vs. 25% in the anti-TNF groups (P = 0.24). In severely active UC, the response rate tended to be higher in patients treated with tacrolimus, albeit not statistically significant. CONCLUSIONS Both tacrolimus and anti-TNF agents appeared to be safe and effective in the management of moderate-to-severe active UC. However, randomised controlled trials are warranted to confirm the results obtained in this study.
