Abstract
BACKGROUND AND PURPOSE CNS lesions of tuberous sclerosis complex are diagnosed mainly by T2WI, FLAIR, and sometimes T1WI with magnetization transfer contrast. The usefulness of T1WI with chemical shift selective images was recently reported in focal cortical dysplasia type IIb, which has histopathologic and imaging features similar to those of tuberous sclerosis complex. We investigated the usefulness of the T1WI with chemical shift selective images in detecting CNS lesions of tuberous sclerosis complex. MATERIALS AND METHODS We retrospectively reviewed 25 consecutive patients with tuberous sclerosis complex (mean age, 11.9 [SD, 8.9] years; 14 males) who underwent MR imaging including T1WI, T1WI with magnetization transfer contrast, T1WI with chemical shift selective, T2WI, and FLAIR images. Two neuroradiologists assessed the number of CNS lesions in each sequence and compared them in 2 steps: among T1WI, T1WI with magnetization transfer contrast and T1WI with chemical shift selective images, and among T2WI, FLAIR, and T1WI with chemical shift selective images. We calculated the contrast ratio of the cortical tubers and of adjacent normal-appearing gray matter and the contrast ratio of radial migration lines and adjacent normal-appearing white matter in each sequence and compared them. RESULTS T1WI with chemical shift selective images was significantly superior to T1WI with magnetization transfer contrast for the detection of radial migration lines and contrast ratio of radial migration lines. There was no significant difference between T1WI with chemical shift selective images and T1WI with magnetization transfer contrast for the detection of cortical tubers and the contrast ratio of the cortical tubers. Both T2WI and FLAIR were statistically superior to T1WI with chemical shift selective images for the detection of cortical tubers. T1WI with chemical shift selective images was significantly superior to T2WI and FLAIR for the detection of radial migration lines. CONCLUSIONS The usefulness of T1WI with chemical shift selective images in detecting radial migration lines was demonstrated. Our findings suggest that the combination of T1WI with chemical shift selective images, T2WI, and FLAIR would be useful to evaluate the CNS lesions of patients with tuberous sclerosis complex in daily clinical practice.

Abstract
INTRODUCTION Regenerative therapy is a developing field in medicine. In the production of cell products for these therapies, hygienic management is even more critical than in the production of a chemical drug. At the same time, however, care is required with the use of decontamination agents, considering their effects on cell viability and characteristics. To date, hydrogen peroxide (H2O2) is most widely used for decontamination in pharmaceutical plants and cell processing facilities. METHODS In this study, we examined the effects of residual H2O2 in the atmosphere of cell processing units after decontamination on the viability and proliferation of mesenchymal stem cells derived from human bone marrow. RESULTS We detected residual H2O2 sufficient to affect cell proliferation and survival even more than 30 h after decontamination ended. Our results suggest a longer time period is required before starting operations after decontamination and that the operating time should be as short as possible. CONCLUSIONS Here we show the effects of post-decontamination residual H2O2 on the viability and proliferation of mesenchymal stem cells derived from human bone marrow, which may provide us with important information about the hygienic management of cell processing facilities.

Abstract
Introduction Current production facilities for Cell-Based Health care Products (CBHPs), also referred as Advanced-Therapy Medicinal Products or Regenerative Medicine Products, are still dependent on manual work performed by skilled workers. A more robust, safer and efficient manufacturing system will be necessary to meet the expected expansion of this industrial field in the future. Thus, the 'flexible Modular Platform (fMP)' was newly designed to be a true "factory" utilizing the state-of-the-art technology to replace conventional "laboratory-like" manufacturing methods. Then, we built the Tissue Factory as the first actual entity of the fMP. Methods The Tissue Factory was designed based on the fMP in which several automated modules are combined to perform various culture processes. Each module has a biologically sealed chamber that can be decontaminated by hydrogen peroxide. The asepticity of the processing environment was tested according to a pharmaceutical sterility method. Then, three procedures, production of multi-layered skeletal myoblast sheets, expansion of human articular chondrocytes and passage culture of human induced pluripotent stem cells, were conducted by the system to confirm its ability to manufacture CHBPs. Results Falling or adhered microorganisms were not detected either just after decontamination or during the cell culture processes. In cell culture tests, multi-layered skeletal myoblast sheets were successfully manufactured using the method optimized for automatic processing. In addition, human articular chondrocytes and human induced-pluripotent stem cells could be propagated through three passages by the system at a yield comparable to manual operations. Conclusions The Tissue Factory, based on the fMP, successfully reproduced three tentative manufacturing processes of CBHPs without any microbial contamination. The platform will improve the manufacturability in terms of lower production cost, improved quality variance and reduced contamination risks. Moreover, its flexibility has the potential to adapt to the modern challenges in the business environment including employment issues, low operational rates, and relocation of facilities. The fMP is expected to become the standard design basis of future manufacturing facilities for CBHPs.

Abstract
1. The E3 ubiquitin protein ligase 1 (WWP1) gene, the mutation of which causes muscular dystrophy in chickens, is expressed not only in the pectoral muscle, but also in a number of tissues such as the kidney. Therefore, this study examined some parameters related to kidney function in muscular dystrophic (MD) chickens. 2. Plasma osmolality, Na+ and K+ concentrations, aldosterone levels, and the expression of aquaporin (AQP) 2, AQP3, and α subunits of the amiloride-sensitive epithelial sodium channel (αENaC) were analysed in the kidneys of 5-week-old MD chickens and White Leghorn (WL) chickens under physiological conditions or after one day of water deprivation. 3. Plasma osmolality, Na+ concentrations, and plasma aldosterone levels were significantly higher in MD chickens than in WL chickens. αENaC mRNA expression levels were lower in MD chickens than in WL chickens. AQP2 and AQP3 mRNA expression levels were similar in the two strains of chickens. 4. Plasma osmolality correlated with aldosterone levels and AQP2 and αENaC mRNA levels in WL chickens. In MD chickens, plasma osmolality correlated with AQP2 mRNA levels, but not with plasma aldosterone or αENaC mRNA levels. 5. These results suggest that neither water reabsorption nor the expression of AQP2 and AQP3 is impaired in MD chickens and that a WWP1 gene mutation may or may not directly induce an abnormality in Na+-reabsorption in the kidneys of MD chickens, potentially through αENaC.

Abstract
Cell therapy and regenerative medicine technologies require strict cell manufacturing procedures to be defined and addressed. Maintenance of the aseptic environment is critical to preclude extrinsic contamination risks, similar to conventional pharmaceutical manufacturing. However, intrinsic contamination risks exist in all cell manufacturing processes owing to the use of cells as the raw materials that cannot be sterilized, thus giving rise to the primary and secondary risks of cell contamination and cross-contamination, respectively. Analysis of contamination risks was conducted on experienced batches (29,858 batches) for the production of immune cells derived from autologous blood mononuclear cells under the Medical Practitioners Act and the Medical Care Act in Japan. From these batches, 0.06% (18 cases) of contamination occurred, representing low probability of contamination incidence during cell processing. Almost all the causes of these contaminations were regarded to be from the collected blood (intrinsic contamination), and subsequent cross-contaminations were prevented, considering that the secondary contamination risk can be reduced by adequate managements of operational procedures for changeover in aseptic environment.

Abstract
Abstract
Introduction
Chemotherapy induced peripheral neuropathy (CIPN) is a major problem for patients who receive chemotherapy, and it sometimes deteriorate patients' QOL. Many CIPN prevention trials have been conducted, but no one succeeded to date.
Objectives
To investigate if frozen glove (FG) prevents peripheral neuropathy induced by nanoparticle albumin-bound paclitaxel (nab-PTX).
Methods
We conducted CIPN prevention study using FG, as part of multi-institutional phase II study which analyze efficacy and safety of nab-PTX (260mg/m2 q3w) followed by FEC (500/100/500 mg/m2, q3w) in pre-operative setting (KBCSG-TR 1213 trial). Each patient wore an FGs for a total of 60 minutes (15mins before and after nab-PTX treatment) on both hands. CIPN were assessed during treatment period with nab-PTX by the Patient Neurotoxicity Questionnaire (PNQ) and the FACT/GOG (Gynecologic Oncology Group) Neurotoxicity (Ntx) subscale. Patients were asked to access PNQ and FACT/GOG Ntx on a daily basis and recorded in the CIPN diary.
Results
Sixty two patients were registered for KBCSG-TR 1213 trial. And forty two pts (68%) who turned in the diary were analyzed. Median age and median body mass index (BMI) was 48 years old and 21.6 kg/m2, respectively. We analyzed following 6 categories, 1) symptoms of hands and arms, 2) symptoms of foots, 3) symptoms of general, 4) symptoms of ears 5) muscle weakness of hands and arms and 6) muscle weakness of foots. Median time to each event was 1) 25.5 days, 2) 5days, 3) 3days, 4) not available, 5) 46.5days, 6)4 days. By using FG, time to event of hands and arms was much longer compared with that of foots.
Conclusions
CIPN could be prevented or lessened by FG. Randomized phase II CIPN prevention study has been just launched.

Abstract
Anti-malarial transmission-blocking vaccines (TBVs) aim to inhibit the transmission of Plasmodium from humans to mosquitoes by targeting the sexual/ookinete stages of the parasite. Successful use of such interventions will subsequently result in reduced cases of malarial infection within a human population, leading to local elimination. There are currently only five lead TBV candidates under examination. There is a consequent need to identify novel antigens to allow the formulation of new potent TBVs. Here we describe the design and evaluation of a potential TBV (BDES-PbPSOP12) targeting Plasmodium berghei PSOP12 based on the baculovirus dual expression system (BDES), enabling expression of antigens on the surface of viral particles and within infected mammalian cells. In silico studies have previously suggested that PSOP12 (Putative Secreted Ookinete Protein 12) is expressed within the sexual stages of the parasite (gametocytes, gametes and ookinetes), and is a member of the previously characterized 6-Cys family of plasmodial proteins. We demonstrate that PSOP12 is expressed within the sexual/ookinete forms of the parasite, and that sera obtained from mice immunized with BDES-PbPSOP12 can recognize the surface of the male and female gametes, and the ookinete stages of the parasite. Immunization of mice with BDES-PbPSOP12 confers modest but significant transmission-blocking activity in vivo by active immunization (53.1% reduction in oocyst intensity, 10.9% reduction in oocyst prevalence). Further assessment of transmission-blocking potency ex vivo shows a dose-dependent response, with up to a 76.4% reduction in intensity and a 47.2% reduction in prevalence observed. Our data indicates that PSOP12 in Plasmodium spp. could be a potential new TBV target candidate, and that further experimentation to examine the protein within human malaria parasites would be logical.

Abstract
The eyes of 2 male and 2 female GSP/pe chickens, the imperfect albino strain, were investigated at 52 weeks of age. Aged chickens of the GSP/pe colony became blind with bilateral ocular enlargement and opaque lenses. Affected eyes (bilateral in 2 males and unilateral in 2 females) were hard and difficult to section; histologic specimens were processed after decalcification. A large portion of the posterior chamber was occupied by cancellous bone containing fibrous and cartilaginous foci. Osseous tissues developed adjacent to the choroid, and no retinal pigment epithelium (RPE) was detected between osseous tissues and the choroid. Small segments of degenerate neuronal retina were scattered in the osseous tissue. The irises and ciliary bodies were deformed by osseous tissue, and the lenses had severe cataracts. These observations suggest that the intraocular osseous tissue may be derived from RPE in the hereditary incomplete-albino strain of chickens.

Abstract
Next-generation sequencing technologies permit rapid and cost-effective identification of numerous putative microsatellite loci. Here, from the genome sequences of Japanese quail, we developed microsatellite markers containing dinucleotide repeats and employed these for characterisation of genetic diversity and population structure. A total of 385 individuals from 12 experimental and one wild-derived Japanese quail lines were genotyped with newly developed autosomal markers. The maximum number of alleles, expected heterozygosity and polymorphic information content (PIC) per locus were 10, 0.80 and 0.77 respectively. Approximately half of the markers were highly informative (PIC ≥ 0.50). The mean number of alleles per locus and observed heterozygosity within a line were in the range of 1.3-4.1 and 0.11-0.53 respectively. Compared with the wild-derived line, genetic diversity levels were low in the experimental lines. Genetic differentiation (FST ) between all pairs of the lines ranged from 0.13 to 0.83. Genetic clustering analyses based on multilocus genotypes of individuals showed that most individuals formed clearly defined clusters corresponding to the origins of the lines. These results suggest that Japanese quail experimental lines are highly structured. Microsatellite markers developed in this study may be effective for future genetic studies of Japanese quail.

Abstract
PURPOSE Better treatments for triple-negative breast cancer (TNBC) are needed. To address this need, we studied the effects of preoperative metronomic paclitaxel/cyclophosphamide/capecitabine (mPCX) followed by 5-fluorouracil (FU)/epirubicin/cyclophosphamide (FEC) as preoperative chemotherapy in TNBC patients. METHODS Forty primary TNBC patients received four cycles of metronomic paclitaxel (80 mg/m(2) on Days 1, 8, and 15), cyclophosphamide (50 mg/body daily), and capecitabine (1,200 mg/m(2) daily), followed by four cycles of 5-FU (500 mg/m(2)), epirubicin (100 mg/m(2)), and cyclophosphamide (500 mg/m(2)) every 3 weeks. The primary end point was the pathological complete response (pCR) rate. RESULTS Forty patients formed the intent-to-treat population. The median dose intensities of paclitaxel, cyclophosphamide, and capecitabine were 89.7, 92.1, and 89.8%, respectively. Five patients discontinued mPCX and two discontinued FEC, primarily because of adverse events, resulting in a per-protocol population (PPS) of 33 patients. The pCR (ypT0/Tis ypN0) rate was 47.5% (19/40) in the intent-to-treat population and 54.5% (18/33) in the PPS. The clinical response rates were 36/40 (90.0%) and 31/33 (93.9%) in the intent-to-treat and PPS, respectively. The breast conservation rate was 72.7% (24/33), and 5/13 patients underwent partial resection instead of pre-planned total mastectomy. Grade 3-4 adverse events included neutropenia (35%), leukopenia (25%), and hand-foot syndrome (8%). CONCLUSIONS Metronomic PCX followed by FEC chemotherapy was associated with a high pCR rate and low toxicity in TNBC patients. Further studies of this regimen in larger numbers of patients are warranted.

Abstract
It is assumed that Red Junglefowl (Gallus gallus) is one of the main ancestors of domestic chickens (Gallus gallus domesticus). Differences in microsatellite polymorphisms between Red Junglefowl and modern commercial chickens, which are used for egg and meat production, have not been fully reported. A total of 361 individuals from 1 Red Junglefowl population that has been maintained as a closed flock, 5 final cross-bred commercial layer populations (white-, tinted-, and brown-egg layers), and 2 final cross-bred commercial broiler populations were genotyped for 40 autosomal microsatellite loci. We compared microsatellite variations in Red Junglefowl with those in a commercial chicken gene pool. The contribution of each population to the genetic diversity was also estimated based on the molecular coancestry. In total, 302 distinct alleles were detected in 1 Red Junglefowl and 7 commercial chicken populations, of which 31 alleles (10.3%) were unique to Red Junglefowl, most of which occurred at a high frequency. The genetic differentiation between Red Junglefowl and commercial chickens (pairwise FST) ranged from 0.32 to 0.47. According to the neighbor-joining tree based on the modified Cavalli-Sforza chord distances and the Bayesian clustering analysis, Red Junglefowl was genetically distant from the commercial chicken gene pool tested. In all of the populations analyzed, Red Junglefowl made the highest contribution to genetic diversity. These results suggest that Red Junglefowl has a distinct distribution of microsatellite alleles and that there is a high level of genetic divergence between Red Junglefowl and commercial chickens.

Abstract
Abstract
Background: We compared and evaluated three 6-cycle, docetaxel and cyclophosphamide (TC)-containing chemotherapy regimens in a multicenter randomized phase II study. The main aim was to investigate whether anthracyclines are needed or can be omitted, and whether the order of chemotherapy is important, for treating luminal-type breast cancer.
Methods: We recruited patients (pts) with ER-positive, HER2-negative breast cancer aged 20–70 years, and histo-pathologically invasive breast cancer (T1c-3, N0-1, M0), T≤7cm. Pts were randomized to 3 groups for the following treatments: 6 cycles of TC; 3 cycles of 5-FU/epirubicin/cyclophosphamide (FEC) followed by 3 cycles of TC (FEC-TC); and 3 cycles of TC followed by 3 cycles of FEC (TC-FEC). TC treatment consisted of administration of docetaxel at 75 mg/m2 and cyclophosphamide at 600 mg/m2 once every 3 weeks. FEC treatment consisted of administration of 5-FU at 500 mg/m2, epirubicin at 100 mg/m2, and cyclophosphamide at 500 mg/m2 once every 3 weeks. We aimed to enroll 65 pts per group based on an expected pCR rate among regimens of adding 10% at a threshold of 9%. The primary endpoint was pathological complete response (pCR) rate. Secondary endpoints were overall response rate (ORR), breast conservation rate and safety.
Results: A total of 195 pts (median age, 49.5 years (range, 26–69); median tumor size, 32.8 mm (range, 9–82); 91 pts with N(+) (51%)) were enrolled and randomized as follows: FEC-TC (n = 65), TC-FEC (n = 63), and TC group (n = 67). There were no differences in backgrounds among groups. Both the intention-to-treat population and the safety analysis set included 65, 63 and 65 pts in these groups, respectively. The 6-cycle treatment completion rates were 96.9%, 96.8% and 84.6%, respectively. pCR, defined as yT0/isyN0, was achieved by 9.2% of pts in the FEC-TC group, 8.1% in the TC-FEC group, and 15.9% in the TC group (p = 0.321). A quasi pCR in breast (yT0/is and near pCR) was achieved by 13.9%, 14.5%, and 17.5%, respectively. These responses did not differ among the 3 groups. ORRs, assessed by MRI or CT, were 75.8% (CR: 12.9%), 75% (CR: 5%), and 82.2% (CR: 17.9%) in the FEC-TC, TC-FEC and TC groups, respectively. Breast conservation rates were 50.8%, 45.2%, and 73.0%, respectively.Adverse events of Grade≥3 were observed in 20.0%, 27.0%, and 20.3% of pts in the FEC-TC, TC-FEC, and TC groups, respectively, with no significant differences. Febrile neutropenia was observed in 17.2%, 21.0%, and 11.3%, respectively, but in most cases it was managed sufficiently on an outpatient basis. Of 28, 27 and 23 pts in these groups in whom mastectomy was planned, 9 (32%), 5 (19%), and 10 (44%) were successfully converted to undergo breast-conserving surgery. Of 37, 35 and 40 pts in the FEC-TC, TC-FEC and TC groups in whom breast-conserving surgery was planned, 13 (35%), 12 (34%), and 4 (10%) underwent mastectomy.
Conclusion: Six cycles of TC had therapeutic effects and safety equivalent to FEC-TC and TC-FEC. The 3 treatment groups showed similar pCR rates, although the breast conservation rate was significantly higher in the TC group than in the other 2 groups. It may be possible to conduct preoperative chemotherapy for pts with ER-positive breast cancer without using an anthracycline.

Abstract
Darjeeling teas are the highest grown teas in the world and preferred for its flavour, aroma and quality. Apart from the genetic makeup of the plant, earlier reports suggest that insect infestation, particularly jassids and thrips triggers the aroma and flavour formation in Darjeeling tea. The present work encompasses the identification of the genes/transcriptomes responsible for the typical flavour of Darjeeling tea, besides understanding the role of jassids and thrips in particular, in producing the best cup character and quality. The quantitative real time PCR analysis was based on a suppression subtractive hybridisation forward library of B157 (tea clone infested with thrips), providing us transcripts related to aroma and flavour formation. We observed the expression of genes like leucine zipper, ntd, nced, geraniol synthase, raffinose synthase, trehalose synthase, amylase, farnesyl transferase, catalase, methyl transferase, linalool synthase, peroxidases, elicitor responsive proteins, linamarase, nerolidol linalool synthase 2, 12-oxophytodienoate reductase, glucosidase, MYB transcription factor, and alcohol dehydrogenase, highly regulated due to insect infestation, manufacturing stresses and mechanical injury. The first report on gene expression dynamics in thrips infested Darjeeling tea leaves can be extrapolated with increase in volatiles which is responsible for enhancing the quality of Darjeeling tea, specially the flavour and aroma of the infusion. We hope to model these responses in order to understand the molecular changes that occur during Darjeeling tea flavour formation.

Abstract
Abstract
OBJECTIVE: Although resection of isolated pulmonary metastases is a common treatment in other primaries such as colon cancer, the role of lung metastasectomy of breast cancer is still unclear. The objective of the present study was to investigate the clinical outcome of our operated patients with isolated pulmonary breast cancer metastases and discuss the clinical implication of resection with curative intent for them.
METHODS: We retrospectively analyzed 86 female patients with histologically proven isolated pulmonary metastases from breast cancer who were treated with surgery of curative intent between January 1980 and September 2010 at 7 Japanese hospitals. The mean age of them was 50 years, the median disease free interval (DFI) from the definitive surgery for the primary breast cancer was 4.6 years (range: 0.5−20.4 years) and the median follow-up after lung metastasectomy was 4.1 years (range: 0.3−30.9 years).
RESULTS: Lung metastasectomy was performed by thoracotomy in 22 patients and by video-assisted thoracoscopic surgical resection in 64 patients. The number of metastatic foci resected was one for 79 patients, two for 6, and unknown for 1. Lymph node resection was performed for 12 patients, was not done for 69, and unknown for 5. Five-year survival rates after lung metastasectomy were 68% in the patients. The main prognostic factor was the DFI. Five-year survival rates for patients with DFI of longer than 2 years (n = 72) and those with DFI of shorter than 2 years (n=14) were 74.5% and 33.8%, respectively (p = 0.0006). Five-year survival rates after lung metastasectomy were 68% in patients without macroscopic residual pulmonary tumor after lung metastasectomy (n = 69) and 34% in those with macroscopic residual tumor (n = 12) (p = 0.023). Five-year disease free survival after lung metastasectomy for patients without macroscopic residual tumor was 51 %. Five-year survival rates were 78% in patient with endocrine hormonal therapy following lung metastasectomy (n = 51) and 53% in those without endocrine hormonal therapy (n = 35) (p = 0.045). No prognostic influence could be demonstrated for age, number of initial axillary node metastases, primary tumor size.
CONCLUSION: The prognosis of the breast cancer patients with isolated pulmonary metastases who underwent metastasectomy with curative intent was good. It was affected by the biological aspects of the primary tumor, “curativity” of the resection, and systemic treatments after lung resection. It may be expected that some of those patients will be cured by surgery with curative intent.

Abstract
BACKGROUND Esophageal stenosis is one of the major complications of aggressive endoscopic resection. Tissue-engineered epithelial cell grafts have demonstrated effectiveness in promoting re-epithelialization and suppressing inflammation causing esophageal scarring and stenosis after endoscopic submucosal dissection (ESD) in an animal model. OBJECTIVE To confirm the reproducibility and efficacy of a human oral mucosal epithelial cell (hOMEC) sheet cultured on temperature-responsive surface in conformity with Good Manufacturing Practice guidelines. DESIGN A preclinical study. SETTING Good Manufacturing Practice grade cell-processing center, animal laboratory. SUBJECTS Canine esophageal ulcer models, which were made by ESD. INTERVENTIONS Oral mucosal specimens were obtained from 7 healthy volunteers. MAIN OUTCOME MEASUREMENT Fabricated and transplanted hOMEC sheets were subjected to histological analysis. RESULTS The reproducibility of the fabrication of hOMEC sheets was confirmed. In this method, animal-derived materials such as 3T3 feeder layer and fetal bovine serum were successfully excluded from the culture condition. Furthermore, the environment of the culture room and safety cabinet in the cell-processing center was maintained for obtaining sterility assurances during the fabrication. Transplanted hOMEC sheets after ESD were observed to graft onto canine esophageal ulcer surfaces. LIMITATIONS Small number of subjects, animal model. CONCLUSIONS Cultured hOMEC sheets were fabricated without animal-derived materials and demonstrated efficacy as a medical device that promotes re-epithelialization of an esophageal ulcer after ESD.

Abstract
To elucidate the strain difference in the sex reversal of genetic female to phenotypic male, GSP and PNP/DO females were left ovariectomized (ovx) between one day to three days after hatching and the degree of masculinization based on sex-related characters, histological analysis of the right gonad and hormone assay were assessed at one year of age. The GSP and PNP/DO inbred lines were both derived from the Fayoumi breed and are only differentiated based on red blood cell antigens type carried by each of the inbred line. Comb and wattles were found to be significantly bigger (P < 0.05) in the GSP ovx compared to the PNP/DO ovx, although male plumage pattern were more pronounced in the PNP/DO ovx. Spurs were observed both in the GSP and PNP/DO ovx with no significant difference (P > 0.05) in length to the respective male controls and body weight were not significantly different (P > 0.05) to the female controls. The size of the right gonad were significantly bigger (P < 0.05) in the GSP ovx than the PNP/DO ovx. Positive correlations were found in the sex related characters as well as plasma testosterone level and the right gonad weight both in the GSP and PNP/DO ovx except for the spur length which resulted into a negative correlation in the PNP/DO ovx. Histological analysis revealed that the right gonad of PNP/DO ovx are morphologically developed compared to GSP ovx showing more advance stages of spermatogenesis. It could be inferred that PNP/DO females which exhibit hereditary persistent right oviduct, are more responsive to the masculinizing effect of ovariectomy compared to GSP females, suggesting that genetic background may have a possible contribution on the degree of masculinization and subsequent development of sex related characters.

Abstract
BACKGROUND The parents of the children who undergo surgery experience stress during the pre-anesthetic period. Such stress influences the mental status of their children, thereby inducing their pre-anesthetic anxiety and problematic behavior at emergence. Recently, measurement of salivary biomarkers was evaluated as stress biomarkers. Especially, alpha-amylase is utilized as an excellent index for psychological stress. In the present study, we tested whether salivary amylase activity of mothers before the surgery of their children correlates with the peri-operative children's behaviors. METHODS A total of 22 pairs of mothers and children were analyzed. Maternal salivary amylase activity was evaluated at the entrance of the operation room. The children underwent minor plastic surgery under general anesthesia, and induction and emergence behaviors were assessed. RESULTS The higher the maternal salivary amylase activity, the severer the children's induction anxiety (r(s)=-0.667, n=22, P<0.0001), and the higher the maternal amylase activity, the severer the children's emergence agitation (r(s)=0.705, n=22, P<0.0001). CONCLUSION Induction and emergence behaviors of children undergoing general anesthesia significantly correlated with their respective maternal salivary amylase activity during the pre-anesthetic period.

Abstract
Background: The purpose of this study was to evaluate the role of contrast-enhanced CT and the usefulness of superselective embolization therapy in the management of arterial damage in patients with severe blunt renal trauma. Patients and methods: Nine cases of severe renal trauma were evaluated. In all cases, we compared contrast-enhanced CT findings with angiographic findings, and performed transcatheter arterial embolization (TAE) in six of them with microcoils and gelatin sponge particles. Morphological changes in the kidney and site of infarction after TAE were evaluated on follow-up CT. Chronological changes in blood biochemistry findings after injury, degree of anemia and renal function were investigated. Adverse effects or complications such as duration of hematuria, fever, abdominal pain, renovascular hypertension and abscess formation were also evaluated. Results: The CT finding of extravasation was a reliable sign of active bleeding and useful for determining the indication of TAE. In all cases, bleeding was effectively controlled with superselective embolization. There was minimal procedure-related loss of renal tissue. None of the patients developed abscess, hypertension or other complications. Conclusions: In blunt renal injury, contrast-enhanced CT was useful for diagnosing arterial hemorrhage. Arterial bleeding may produce massive hematoma and TAE was a useful treatment for such cases. By using selective TAE for a bleeding artery, it was possible to minimize renal parenchymal damage, with complications of TAE rarely seen.

Abstract
The panda mutant in Japanese quail (Coturnix japonica) displays spots of wild-type plumage on a white background and is controlled by an autosomal recessive allele (s). The dotted white is controlled by a third allele (s(dw)) of the s locus with s(dw)/s(dw) quail having less pigmentation than s/s quail. We mapped the s locus to the Japanese quail chromosome 4 (CJA04) in a previous study. The orthologous region of the chicken (Gallus gallus) genome includes endothelin receptor B2 (EDNRB2), an avian-specific paralog of endothelin receptor B (EDNRB). EDNRB mutations in mammals retard the migration of neural crest cells (NCCs), which results in a spotted coat colour and an enteric nervous defect. In the present study, we investigated the association between the s locus and EDNRB2 in Japanese quail. Sequence comparison among transcripts from livers of wild-type, panda and dotted white quail revealed a nucleotide substitution (c.995G>A) leading to a p.R332H amino acid change that was specific to panda, whereas no amino acid substitution was found in dotted white birds. The amino acid position 332 is located in the sixth transmembrane domain and is highly conserved in both avian and mammalian endothelin receptors. The A allele at nucleotide position 995 was specific to panda (s/s) birds among 10 strains, and was mapped to the same chromosomal region as the s locus. Quantitative RT-PCR revealed that EDNRB2 transcripts were reduced in both panda and dotted white mutants compared with wild-type. However, there was no difference between the early embryos of wild-type and panda with respect to the migration of NCCs. The genetic association of EDNRB2 with plumage colour in birds was found for the first time in this study.

Abstract
Sterols are isoprenoid-derived lipids that are produced via the mevalonate pathway and are involved in various cellular functions in eukaryotes such as maintenance of membrane integrity and biosynthetic precursors of steroid hormones. Among cellular sterols, Δ22-sterols containing a double bond at C-22 in the sterol side chain specifically occur in fungi (ergosterol) and plants (stigmasterol and brassicasterol), and several lines of experimental evidence have suggested specific physiological roles of Δ22-sterols in plants. Fungal cytochrome P450 (P450), CYP61, has been established as the sterol C-22 desaturase functioning at the penultimate step in the ergosterol biosynthetic pathway. On the other hand, no particular sequence has been assigned as to the enzyme responsible for the introduction of the double bond into the sterol side chain in plants. In this review, we summarize our recent findings demonstrating that CYP710A P450 family genes encode the plant sterol C-22 desaturases to produce stigmasterol and brassicasterol/crinosterol from β-sitosterol and 24-epi-campesterol respectively.
