Abstract
BACKGROUND Tracheal intubation sometimes causes postoperative sore throat (POST) due to laryngeal damage. However, clinical observations suggest that the environment of the oral cavity may also affect POST. OBJECTIVE The purpose of this study was to investigate whether salivary pH in the oral cavity affects POST. METHODS After obtaining ethical approval, informed consent was obtained from all patients. Patients who underwent surgery in the supine position were enrolled as the control group. Patients who underwent laparoscopic surgery in the head-down position were enrolled as the intervention group. Immediately before both groups of patients were anaesthetised, expelled saliva was collected, and salivary pH was measured. Immediately postoperatively, the same measurement was carried out before the patient regained consciousness. The primary outcome was the change in salivary pH. The secondary outcome was POST. In our study, POST was defined as pharyngeal and swallowing pain in the glossopharyngeal and superior laryngeal nerves. The normal distribution of pH was tested using the Shapiro-Wilk test followed by analysis using repeated-measurements and one-way analysis of variance. Statistical significance was set at p < .05. RESULTS A total of 62 patients were enrolled, of whom two were excluded based on the exclusion criteria. Salivary pH in the intervention group was significantly lower than that in the control group. Five patients had POST in the intervention group, whereas none had POST in the control group had POST. CONCLUSION Acidotic-shifted saliva is considered one of the causes of POST.

Abstract
The frequency of cleft lip with/without palate (CL/P) in the Mongolian population is approximately 1 in 1314 live births. This research aims to disseminate information about this congenital disability to the public to better understand CL/P, and people's fissures, and review administrative measures, as there is a lack of research in this area. A questionnaire survey was conducted using Google Forms, with 1000 Mongolian participants. Most participants (86.7%) said they had knowledge of the word, whereas 86.2% said they had knowledge of the condition. Most participants' answers were question-related disadvantages of CL/P patients, including statements such as "It's uncomfortable in human relationships" and "It makes an uncomfortable impression on the person you meet the first time." The results of this study revealed that most Mongolians were aware of CL/P and are concerned about patients. However, the causes of CL/P in the general population remain unknown, and further research is needed in this area.

Abstract
Since telepractice regulation does not yet exist in Japan, we assessed telepractice efficacy and the level of satisfaction with telepractice versus that with face-to-face practice (FTFP) in speech therapy to establish effective telepractice in Japan. Changes in the number of therapy sessions and therapy levels were compared between telepractice and FTFP sessions conducted during the study period. Additionally, the patients' parents completed a questionnaire survey regarding telepractice. The mean number of sessions was not significantly different between the two types of therapy; the therapy levels, according to stepwise speech therapy, either increased or remained unchanged. The survey showed satisfaction with telepractice among all parents. Telepractice for cleft palate speech was delivered successfully with complete parental satisfaction.

Abstract
This study aims to identify potential variants in the TP63-IRF6 pathway and GREM1 for the etiology of non-syndromic orofacial cleft (NSOFC) among the Vietnamese population. By collecting 527 case-parent trios and 527 control samples, we conducted a stratified analysis based on different NSOFC phenotypes, using allelic, dominant, recessive and over-dominant models for case-control analyses, and family-based association tests for case-parent trios. Haplotype and linkage disequilibrium analyses were also conducted. IRF6 rs2235375 showed a significant association with an increased risk for non-syndromic cleft lip and palate (NSCLP) and cleft lip with or without cleft palate (NSCL/P) in the G allele, with pallele values of 0.0018 and 0.0003, respectively. Due to the recessive model (p = 0.0011) for the NSCL/P group, the reduced frequency of the GG genotype of rs2235375 was associated with a protective effect against NSCL/P. Additionally, offspring who inherited the G allele at rs2235375 had a 1.34-fold increased risk of NSCL/P compared to the C allele holders. IRF6 rs846810 and a G-G haplotype at rs2235375-rs846810 of IRF6 impacted NSCL/P, with p-values of 0.0015 and 0.0003, respectively. In conclusion, our study provided additional evidence for the association of IRF6 rs2235375 with NSCLP and NSCL/P. We also identified IRF6 rs846810 as a novel marker associated with NSCL/P, and haplotypes G-G and C-A at rs2235375-rs846810 of IRF6 associated with NSOFC.

Abstract
Cleft lip and/or palate anomalies (CL ± P) are the most frequent birth defects affecting the orofacial region in humans. Although their etiology remains unclear, the involvement of environmental and genetic risk factors is known. This observational study aimed to investigate how the use of crude drugs with estrogen activity influenced an animal model's ability to prevent CL ± P. A/J mice were randomly divided into six experimental groups. Five of these groups consumed a drink containing crude drug licorice root extract, with the following weights attributed to each group: 3 g in group I, 6 g in group II, 7.5 g in group III, 9 g in group IV, and 12 g in group V, whereas a control group consumed tap water. The effect of licorice extract was examined for fetal mortality and fetal orofacial cleft development compared to the control group. The rates for fetal mortality were 11.28%, 7.41%, 9.18%, 4.94%, and 7.90% in groups I, II, III, IV, and V, respectively, compared to 13.51% in the control group. There were no significant differences in the mean weight of alive fetuses in all five groups compared to the control group (0.63 ± 0.12). Group IV showed the lowest orafacial cleft occurrence of 3.20% (8 fetuses) with statistical significance (p = 0.0048) out of 268 live fetuses, whereas the control group had the occurrence of 8.75% (42 fetuses) among 480 live fetuses. Our study showed that the dried licorice root extract may reduce orofacial birth defects in experimental animal studies.

Abstract
BACKGROUND We believe that parental presence before the induction of anesthesia for surgery among children with a cleft palate/lip would be effective in mitigating their preoperative anxiety. OBJECTIVE We assessed the states of patients with a cleft palate/lip when their parents accompanied them into operating rooms and clarified their and their parents' cognition using a questionnaire. METHODS Data were collected via nursing observation when patients and their parents entered the operating room. Furthermore, an anonymous questionnaire was administered to patients and parents after the operation regarding their feelings about parental presence in the operating room. RESULTS In total, nine patients cried when they entered the surgical room. Furthermore, six patients and three parents reported preoperative anxiety. In addition, eight patients agreed that they were satisfied with the presence of their parents before induction. CONCLUSION Approximately half of the patients cried. However, the presence of parents before the induction of anesthesia was effective in reducing anxiety among most patients and their parents.

Abstract
Von Recklinghausen's disease is characterized by skin pigmentation, multiple neurofibromatosis, and osseous changes. In the anesthetic management of patients with von Willebrand's disease, it is important to provide appropriate airway management, taking into account the cutaneous laxity caused by neurofibromatosis of Recklinghausen's disease. This case describes the perioperative management of a patient with Recklinghausen's disease with suspected difficulty in airway management.

Abstract
We have been conducting a survey on the birth prevalence of orofacial clefts, including cleft lip with or without cleft palate and cleft palate, in the Tokai area in central Japan every year for 37 years. Along with the yearly trends in the birth prevalence of orofacial clefts in that area for the past 37 years, we discuss whether the artificial abortion rate of fetuses with orofacial clefts has increased through the improved performance of ultrasonic imaging equipment. We also compare the yearly trends in the birth prevalence of congenital anomalies, including orofacial clefts, in Japan with those in other countries or areas where artificial abortion due to birth defects is legally permitted, and discuss the impact of improved accuracy of ultrasound imaging on the rate of artificial termination of pregnancy. The fact that the birth prevalence of orofacial clefts has basically remained unchanged for more than 30 years, even with recent more detailed prenatal diagnosis based on the improvement of ultrasonic diagnostic equipment, has allowed us tentatively to conclude that prenatal diagnosis is not currently threatening the right to life of the fetuses with orofacial clefts.

Abstract
Aims Dozens of causative genes and their mechanisms of nonsyndromic cleft lip with or without cleft palate (NSCL/P) were revealed through genome‐wide association and linkage studies. Results were, however, not always replicated in different populations or methodologies. This study used case–control and family based approaches to investigate the etiology of NSCL/P and its two subtypes: nonsyndromic cleft lip only (NSCLO) and nonsyndromic cleft lip and palate (NSCLP) among the Vietnamese population. Methods Two hundred and seventeen NSCL/P case‐parent trios (one affected child and two parents), including 105 NSCLO and 112 NSCLP were involved for a family based design; and 273 ethnic and region‐matched healthy controls with no cleft history in their families were recruited for a case–control design. Three SNPs consisting of TFAP2A (rs1675414 and rs303048) and 8q24 (rs987525) were genotyped using the TaqMan SNP genotyping assay. Results TFAP2A rs1675414 was associated with NSCLO, replicated by both case‐control and family based tests. Other SNPs yielded no evidence of susceptibility to NSCL/P or two subtypes. Conclusion The current investigation suggests an intriguing role of TFAP2A in the etiology of NSCLO among the Vietnamese population. This study used case‐control and family‐based approaches to investigate the etiology of NSCL/P and its two subtypes: nonsyndromic cleft lip only (NSCLO), nonsyndromic cleft lip and palate (NSCLP) among Vietnamese population. TFAP2A rs1675414 was associated with NSCLO, replicated by both case‐control and family‐based tests.

Abstract
SPECC1L mutations have been identified in patients with rare atypical orofacial clefts and with syndromic cleft lip and/or palate (CL/P). These mutations cluster in the second coiled-coil and calponin homology domains of SPECC1L and severely affect the ability of SPECC1L to associate with microtubules. We previously showed that gene-trap knockout of Specc1l in mouse results in early embryonic lethality. We now present a truncation mutant mouse allele, Specc1lΔC510, that results in perinatal lethality. Specc1lΔC510/ΔC510 homozygotes showed abnormal palate rugae but did not show cleft palate. However, when crossed with a gene-trap allele, Specc1lcGT/ΔC510 compound heterozygotes showed a palate elevation delay with incompletely penetrant cleft palate. Specc1lcGT/ΔC510 embryos exhibit transient oral epithelial adhesions at E13.5, which may delay shelf elevation. Consistent with oral adhesions, we show periderm layer abnormalities, including ectopic apical expression of adherens junction markers, similar to Irf6 hypomorphic mutants and Arhgap29 heterozygotes. Indeed, SPECC1L expression is drastically reduced in Irf6 mutant palatal shelves. Finally, we wanted to determine if SPECC1L deficiency also contributed to non-syndromic (ns) CL/P. We sequenced 62 Caucasian, 89 Filipino, 90 Ethiopian, 90 Nigerian and 95 Japanese patients with nsCL/P and identified three rare coding variants (p.Ala86Thr, p.Met91Iso and p.Arg546Gln) in six individuals. These variants reside outside of SPECC1L coiled-coil domains and result in milder functional defects than variants associated with syndromic clefting. Together, our data indicate that palate elevation is sensitive to deficiency of SPECC1L dosage and function and that SPECC1L cytoskeletal protein functions downstream of IRF6 in palatogenesis.

Abstract
IMPACT STATEMENT The rat palatine fissure is anatomically similar to human alveolar cleft. In this study, we examined potential bone repair by an autologous bone implant and beta-tricalcium phosphate (β-TCP) using rat palatine fissure as a model. Autologous bone chips or β-TCP granules were implanted into the rat palatine fissure. Our model demonstrated that higher bone volume and bone mineral density were achieved with autologous bone graft than with β-TCP. We have provided the first demonstration of the suitability of the rat palatine fissure as the implant site to simulate the transplantation of bone graft materials into human alveolar cleft.

Abstract
Special AT-rich sequence-binding protein 2 (SATB2)-associated syndrome (SAS) is characterized by alterations of SATB2. Its clinical features include intellectual disability and craniofacial abnormalities, such as cleft palate, dysmorphic features, and dental abnormalities. Here, we describe three previously undiagnosed, unrelated patients with SAS who exhibited dental abnormalities, including multiple odontomas. Although isolated odontomas are common, multiple odontomas are rare. Individuals in families 1 and 3 underwent whole-exome sequencing. Patient 2 and parents underwent targeted amplicon sequencing. On the basis of the hg19/GRCh37 reference and the RefSeq mRNA NM_001172517, respective heterozygous mutations were found and validated in Patients 1, 2, and 3: a splice-site mutation (chr2:g.200137396C > T, c.1741-1G > A), a nonsense mutation (chr2:g.200213750G > A, c.847C > T, p.R283*), and a frame-shift mutations (chr2:g.200188589_200188590del, c.1478_1479del, p.Q493Rfs*19). All mutations occurred de novo. The mutations in Patients 1 and 3 were novel; the mutation in Patient 2 has been described previously. Tooth mesenchymal cells derived from Patient 2 showed diminished SATB2 expression. Multiple odontomas were evident in the patients in this report; however, this has not been recognized previously as a SAS-associated phenotype. We propose that multiple odontomas be considered as an occasional manifestation of SAS.

Abstract
To evaluate the association between the single nucleotide polymorphism (SNP) rs227493 in the MEOX2 gene and nonsyndromic cleft palate only, this research was conducted as a case-control study by comparing a nonsyndromic cleft palate only group with an independent, healthy, and unaffected control group who were both examined by specialists. Based on clinical examination and medical records, we analyzed a total of 570 DNA samples, including 277 cases and 293 controls, which were extracted from dry blood spot samples collected from both the Odonto and Maxillofacial Hospital in Ho Chi Minh City and Nguyen Dinh Chieu Hospital in Ben Tre province, respectively. The standard procedures of genotyping the specific SNP (rs2237493) for MEOX2 were performed on a StepOne Realtime PCR system with TaqMan SNP Genotyping Assays. Significant statistical differences were observed in allelic frequencies (allele T and allele G) between the non-syndromic cleft palate only and control groups in female subjects, with an allelic odds ratio of 1.455 (95% confidence interval: 1.026-2.064) and P < 0.05. These study findings suggest that nonsyndromic isolated cleft palate might be influenced by variation of MEOX2, especially SNP rs2237493 in Vietnamese females.

Abstract
Homeobox genes play important roles in craniofacial morphogenesis. However, the characteristics of the transcription factor Hoxc during palate formation remain unclear. We examined the immunolocalization patterns of Hoxc5, Hoxc4, and Hoxc6 in palatogenesis of cleft palate (Eh/Eh) mice. On the other hand, mutations in the FGF/FGFR pathway are exclusively associated with syndromic forms of cleft palate. We also examined the immunolocalization of Fgfr1 and Erk1/2 to clarify their relationships with Hoxc in palatogenesis. Some palatal epithelial cells showed Hoxc5 labeling, while almost no labeling of mesenchymal cells was observed in +/+ mice. As palate formation progressed in +/+ mice, Hoxc5, Hoxc4, and Hoxc6 were observed in medial epithelial seam cells. Hoxc5 and Hoxc6 were detected in the oral epithelium. The palatal mesenchyme also showed intense staining for Fgfr1 and Erk1/2 with progression of palate formation. In contrast, the palatal shelves of Eh/Eh mice exhibited impaired horizontal growth and failed to fuse, resulting in a cleft. Hoxc5 was observed in a few epithelial cells and diffusely in the mesenchyme of Eh/Eh palatal shelves. No or little labeling of Fgfr1 and Erk1/2 was detected in the cleft palate of Eh/Eh mice. These findings suggest that Hoxc genes are involved in palatogenesis. Furthermore, there may be the differences in the localization pattern between Hoxc5, Hoxc4, and Hoxc6. Additionally, Hoxc distribution in palatal cells during palate development may be correlated with FGF signaling. (228/250 words) © 2016 Japanese Teratology Society.

Abstract
Background: Narrowed true lumen and patent false lumen through to the terminal aorta is a high-risk condition for malperfusion syndromes (MS) in acute type-A aortic dissection. It is important to ascertain how the true and false lumens behave after surgery. Patients and Methods: We retrospectively investigated 45 patients with this pathology. The true lumen sizes at the narrowest levels above and below the superior mesenteric artery were followed by computed tomography after surgery (0-36 months). Results: Thirty-seven MS were seen in 23 patients. Hospital mortality was 8.9%. The narrowed true lumen was not enlarged in the first 6 months with a patent false lumen. The elephant trunk procedure did not improve the true lumen size. An extremely narrowed (≤3mm) true lumen was associated with a significantly high incidence of MS and mortality. Conclusions: High incidences of MS were observed in this particular pathology. An extremely narrowed true lumen was accompanied by a high incidence of MS and mortality.

Abstract
Following recent genome wide association studies (GWAS), significant genetic associations have been identified for several genes with nonsyndromic cleft lip with or without cleft palate (CL(P)). To replicate two of these GWAS signals, we investigated the role of common and rare variants in the PAX7 and VAX1 genes. TaqMan genotyping was carried out for SNPs in VAX1 and PAX7 and transmission disequilibrium test (TDT) was performed to test for linkage and association in each population. Direct sequencing in and around the PAX7 and VAX1 genes in 1,326 individuals of European and Asian ancestry was done. The TDT analysis showed strong associations with markers in VAX1 (rs7078160, P = 2.7E-06 and rs475202, P = 0.0002) in a combined sample of Mongolian and Japanese CL(P) case-parent triads. Analyses using parent-of-origin effects showed significant excess transmission of the minor allele from both parents with the effect in the mothers (P = 6.5E-05, OR (transmission) = 1.91) more striking than in the fathers (P = 0.004, OR (transmission) = 1.67) for VAX1 marker rs7078160 in the combined Mongolian and Japanese samples when all cleft types were combined. The rs6659735 trinucleotide marker in PAX7 was significantly associated with all the US cleft groups combined (P = 0.007 in all clefts and P = 0.02 in CL(P)). Eight rare missense mutations found in PAX7 and two rare missense mutations in VAX1. Our study replicated previous GWAS findings for markers in VAX1 in the Asian population, and identified rare variants in PAX7 and VAX1 that may contribute to the etiology of CL(P). Determining the role of rare variants clearly warrants further investigation.

Abstract
The treatment, research and volunteer work for cleft lip and/or palate (CL/P) has been led for over 30 years by our team. Within this period, more than 4,000 cases of CL/P were treated and at the same time, and approximately 400 papers were published as the first or partner researcher in Nature Genetics, New England Journal of Medicine and others. In addition, with $20 million that was donated from companies and laypeople, and the grant from the Japanese government, CL/P centres in many countries and in Japan, the oral and craniofacial congenital anomaly gene bank in our CL/P centre was established by our leadership. In the bank there are genes from approximately more than 8,000 cases. The genes were mapped with Professor Jeffery Murray of Iowa University in the United States, the findings about genetic syndromes such as Van der Woude Syndrome and basal cell nevus syndrome were applied in clinical settings. The genetic counselling section that specialises in the oral and maxillofacial field was established by our effort for the first time in Japan. In this review, our clinical experience and approach for genetic diagnoses and prevention of cleft lip and/or palate will be discussed.

Abstract
Mouse embryos exposed to 2,3,7,8-tetrachloridedibenzo-p-dioxin (TCDD) develop cleft palates and hydronephrosis. Cleft palates occur after TCDD exposure due to contact and/or fusion failure. We investigated whether cleft palate can be induced by dissociation of the palatine process after fusion. Pregnant mice on gestational day (GD) 12 were randomly divided into two groups: one group was administered through gastric tubes one dose of olive oil (control group) and the other group was administered one dose of TCDD diluted with olive oil, both at a dose of 40 microg/kg body weight. Embryos were removed by cesarean section from pregnant mice during the palatal formation stage (GD 13-18) and the palatal form was observed using a stereoscopic microscope. In TCDD-exposed embryos, palatal fusion was observed on GD 14, 15 and 16 and the incidence of cleft palate was 100% on GD 18. Fusion rates were 17.5 +/- 15.2% and 12.4 +/- 11.8% on GD 15 and 16, respectively. Some palates from the TCDD-exposed mouse embryos showed clearly developed cleft palate after fusion of the lateral palatine processes during palatal formation. A mass of cells, which were chiefly epithelial in the fused palates was observed in the TCDD-exposed mouse embryos. A decrease in E-cadherin expression was observed in this mass of cells, indicating its involvement in the development of cleft palate.

Abstract
AIMS/HYPOTHESIS The involvement of chronic inflammation in albuminuria and renal function was investigated in a cross-sectional study of 320 type 2 diabetic Chinese patients from the Singapore Diabetes Cohort Study. METHODS Plasma levels of TNF-alpha and its two cellular receptors and of IL-6 and C-reactive protein (CRP) were measured. A composite TNF-alpha score was extracted using principal component analysis. Multiple linear regression analysis was implemented to evaluate the relationship between log( e ) (ln) albumin:creatinine ratio (ACR) and estimated GFR (eGFR) with the inflammatory variables and other clinical covariates. A Bonferroni correction was applied based on the total number of variables entered into regression analyses. RESULTS ln ACR was significantly associated with TNF-alpha score independently of eGFR even after a Bonferroni correction. TNF-alpha score was also significantly associated with eGFR independently of ln ACR even after correction for multiple testing. These findings were similar when the individual molecules of the TNF-alpha system were analysed separately instead of using the composite TNF-alpha score. No association was observed for IL-6 and CRP with either renal trait. Diabetes duration was a significant predictor for ln ACR but not eGFR. Conversely, age was significantly associated with eGFR but not ln ACR. CONCLUSIONS/INTERPRETATION Activation of the TNF-alpha system may potentially exert independent effects on ln ACR and eGFR in type 2 diabetes. Because of the study design, one may also consider the possibility that changes in these renal traits may conversely be responsible for such an inflammatory response.

Abstract
Morphological and immunohistological examinations were performed to reveal the mechanisms of cleft palate induction by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). ICR strain mice 8-10 weeks of age were used in the study. TCDD was administered in olive oil on gestation day (GD) 12.5 with gastric tubes at 40 microg/kg. From GD 13.5 to 16.5, palates were examined by scanning electron microscopy (SEM), hematoxyline-eosin (HE) staining, and immunohistochemical staining of FGFR1/2, TGF-beta3, MSX1 and LHX8. In the control group, both of the palatal shelves began elevating on GD 14.0 and finished within 6 h. After the elevation, all of the shelves had completely fused with each other on GD 14.5. In the TCDD-treated group, palatal shelves elevated 1 day later than in the control group. However, all palates had elevated by GD 15.0. After the elevation, the shelves contacted each other and fused; however, they were separated on GD16.0. HE staining showed that medial edge epithelium (MEE) was thinner in the TCDD group than in the control group. MEE observed under a high magnification (x2500) exhibited filopodia-like filaments and the cells were bulged in the control group. In contrast, in the TCDD group, no filaments were observed and the cells were flat with unclear boundaries. Immunohistologically, there were no characteristic findings except for FGFR1. FGFR1 was not expressed in the TCDD group after the fusion phase (GD 14.5). TCDD induces many morphological and molecular changes to MEE cells and causes cleft palates.

Abstract
OBJECTIVES The aim of the present study is to clarify the relationship between nasalance scores and nasopharyngeal shapes obtained by lateral cephalograms. PATIENTS Eight patients who underwent a Wardill-Kilner push-back palatoplasty were included in this study. Perceptual judgment by a speech pathologist indicated that these patients had no hypernasality and no nasal emission at blowing. As normal controls, 33 non-cleft individuals, 4 boys and 10 girls aged 6 years old and 5 boys and 14 girls aged 7 years old, were investigated. METHODS Lateral cephalograms at rest were taken for both groups. For the cleft (palate) patients, lateral cephalograms at phonation /a/ and blowing were analyzed and nasometries were also performed using a kitsutsuki passage. RESULTS AND CONCLUSION There was no significant difference in the velar length, the pharyngeal depth, the ratio of the velar length to the pharyngeal depth and the velar angle between the cleft patients and the non-cleft individuals. Multiple regression analyses indicated that standardized regression coefficients of ratios for the velar length to the pharyngeal depth and the velar ascent at blowing had higher nasalance scores for sentences 1 and 3, which had high coefficients of determination, respectively.

Abstract
OBJECTIVES The aim of the present study was to determine whether there are dialectal and gender-related differences in nasalance scores for normal Japanese speakers. MATERIALS Sixty-eight volunteers consisting of 31 males (age 23.8+/-2.0) and 37 females (age 23.2+/-2.5) were included in this study. They had no diseases affecting speech, and lived in the same region until high school from birth. According to geography, they were divided into four regional groups: Chugoku region, Kinki region, Shikoku region, and other regions. METHODS A kitsutsuki passage, which consisted of Japanese non-nasal consonants and vowels, and the Japanese vowels /a/, /i/, /u/, /e/ and /o/, were read three times, and the mean nasalance scores were then obtained with a Nasometer II 6400. The scores of males and females were compared statistically by means of a Student's t-test. The differences among the three regions, Chugoku, Kinki and Shikoku region, were also investigated by means of a one-way analysis of variance (ANOVA). RESULTS AND CONCLUSION For all sentences and vowels, the nasalance scores were significantly different between males and females. The one-way ANOVA showed that there were no significant differences among the three regions in both males and females.

Abstract
It is well-known that TCDD (2,3,7,8, tetrachloridedibenzo-p-dioxin) induces cleft palates (CPs) in pregnant C57BL mice. However, it is unclear if TCDD is a possible teratogen for cleft lip. We examined maxillofacial malformations including cleft lip in three animal strains: A/J mice, C57BL/6J mice and ICR mice. The A/J mouse develops cleft lip and palate spontaneously at a 5-10% rate. TCDD was administered in olive oil on gestation day (GD) 12.5 with gastric tubes at 10 microg/kg, 20 microg/kg, or 40 microg/kg to examine the dose-response, and on a single day from GD 8.5-14.5 to examine the timing effects of TCDD administration on lip and palate formation. Furthermore, the palatal shelf movements during GD 8.5-14.5 were observed with a stereoscopic microscope. All embryos had cleft palates when the TCDD was administered just before palatogenesis (GD11.5-GD12.5). With respect to the TCDD effects, there were large differences among the strains. In the A/J mice, the difference between a lethal dose and a dose that could induce a cleft palate was close. Cleft lips were not induced, even when the TCDD was given just before labiogenesis. Morphologically, both palatal shelves contacted perfectly along their lengths, but separated and formed cleft palates. In conclusion, TCDD is a strong inducer of cleft palates, and interferes with the fusion phase of the secondary palate, but has no effect on the lip.

Abstract
BACKGROUND The aim of this study was to compare hospital, early, and late clinical outcomes for patients undergoing one-stage, coronary and abdominal aortic surgical intervention with and without cardiopulmonary bypass. METHODS From March 1990 to September 1999, 42 consecutive patients underwent combined operations at a single institution. Cardiopulmonary bypass and cardioplegic arrest were used during coronary revascularization in the first 20 patients (on-pump group), and the next 22 patients received the one-stage operations on the beating heart (off-pump group). RESULTS Baseline characteristics were similar between groups. Three cardiac-related hospital deaths occurred in the on-pump group and one such death in the off-pump group (p = 0.25). Cardiac-related events, pulmonary complications, inotropic support, blood loss and transfusion requirements, intensive care unit stay, and hospital stay were significantly reduced in the off-pump group (all, p < 0.05). The actuarial survival rates in the on-pump and off-pump groups were 80% and 95%, respectively, at 1 year (p = 0.13) and 75% and 89%, respectively, at 3 years (p = 0.22). Freedom from cardiac-related events at 1-year follow-up was 91% in the off-pump group and 65% in the on-pump group (p < 0.05). No difference in cardiac-related events between groups was observed at 3 years. CONCLUSIONS Off-pump coronary surgical procedures decrease postoperative complications in high-risk patients undergoing simultaneous coronary and abdominal aortic operations compared with the conventional one-stage procedure. The early benefits achieved with off-pump surgical intervention are not at the expense of the long-term clinical outcome.

Abstract
Synergistic enhancement of the extraction of lanthanoid(III) (Ln) with 2-thenoyltrifluoroacetone (Htta) in benzene has been found by the addition of tris(4-isopropyltropolonato)cobalt(III) (Co(ipt)3). The synergistic effect of Co(ipt)3 was ascribed to the formation of a 1:1 adduct of Ln(tta)3 with Co(ipt)3, i.e., a binuclear complex, in the organic phase. The adduct formation constant (beta s,1) determined by the extraction equilibrium analysis was reasonably consistent with that determined by spectrophotometry. The beta s,1 values decreased with increase in the atomic number of Ln and showed a large difference between light and heavy Ln. Spectroscopic studies were performed to explain the difference in the beta s,1 values. Electronic absorption spectra showed that the change in the structure of Co(ipt)3 complexed with the light Ln chelate is larger than that with the heavy Ln. The IR spectra showed the displacement of the coordinated water molecules of the light Ln chelates with Co(ipt)3. On the other hand, the adduct formation of heavy Ln was caused by the hydrogen bonding between Co(ipt)3 and the coordinated water of the Ln chelate.

Abstract
BACKGROUND Current cardioplegic protection techniques used in pediatric cardiac surgery do not take into consideration age and cyanotic differences. The aim of the present work was to address this question by monitoring clinical outcome, myocardial metabolism, and reperfusion injury in pediatric patients protected by cold-crystalloid cardioplegia. METHODS AND RESULTS Fifty-eight patients (31 children and 27 infants) with or without hypoxic stress (cyanosis) undergoing open heart surgery with cold-crystalloid cardioplegia were included in the study. Clinical outcome measures assessed included inotropic and ventilatory support, intensive care, and hospital stay. Ischemia-induced changes in metabolism (adenine nucleotides, purines, lactate, and amino acids) were determined in ventricular biopsies collected at the beginning and end of ischemic time (cross-clamp time). Reperfusion injury was assessed by measuring postoperative serial release of troponin I. Evidence was observed of ischemic stress during cardioplegic arrest in children and infants as shown by significant changes in cellular metabolites. Compared with infants, children had significantly less reperfusion injury and better clinical outcome, and these factors were related to duration of ischemic time. Cyanosis did not influence outcome in infants, but cyanotic children showed worse reperfusion injury and clinical outcome than acyanotic children. CONCLUSIONS Extent of myocardial protection with cold-crystalloid cardioplegia in pediatric open heart surgery is dependent on age and degree of cyanosis.

Abstract
Since the human genome project has been almost completed in 2000, the year of 2001 is the first year of the postgenomic era. A variety of postgenome studies will be done in the next decade, including functional, comparative and structural genomics. These studies may open new area in medicine, because disease susceptibility and drug metabolism would be predicted from genetic characteristics of individuals. Genome studies may also shed a light on cell biology, brain research and regeneration medicine and promote these studies. Bioinformatics will become a basis of postgenome biology and medicine.

Abstract
The introduction of Evidence-based medicine(EBM) for residency training is recommended by the Japanese Society of Internal Medicine. At our hospital, we put the emphasis on learning vital clinical epidemiology through clinical experience. When educating EBM to our residents, we especially focus on the diagnostic process, because the knowledge of clinical epidemiology is useful while making the diagnosis and evaluating the diagnostic hypothesis. In our daily conference among residents and medical educators, the logic of clinical epidemiology is used for evaluating the validity of clinical judgment on diagnosis. We suggest three components upon making a diagnosis: 1. Always suspect a particular disease when ordering a laboratory test 2. Know the sensitivity and specificity of the test 3. Apply the test result in order to reevaluate the pretest hypothesis In this article, interaction among staff and residents are presented and discussed with these components in our minds. By repeating these interactions, the residents will be able to understand the importance of EBM and will be able to apply it in the clinical practice.

Abstract
The enzyme UDP-glucose: hydroxycoumarin 7-O-glucosyltransferase (CGTase), which catalyzes the formation of scopolin from scopoletin, was purified approximately 1200-fold from a culture of 2,4-D-treated tobacco cells (Nicotiana tabacum L. cv. Bright Yellow T-13) with a yield of 7%. Purification to apparent homogeneity, as judged by SDS-PAGE, was achieved by sequential anion-exchange chromatography, hydroxyapatite chromatography, gel filtration, a second round of anion-exchange chromatography, and affinity chromatography on UDP-glucuronic acid agarose. The purified enzyme had a pH optimum of 7.5, an isoelectric point (pI) of 5.0, and a molecular mass of 49 kDa. The enzyme did not require metal cofactors for activity. Its activity was inhibited by Zn(2+), Co(2+) and Cu(2+) ions, as well as by SH-blocking reagents. The K(m) values for UDP-glucose, scopoletin and esculetin were 43, 150 and 25 µM, respectively. A study of the initial rate of the reaction suggested that the reaction proceeded via a sequential mechanism. The purified enzyme preferred hydroxycoumarins as substrates but also exhibited significant activity with flavonoids. A database search using the amino terminus amino acid sequence of CGTase revealed strong homology to the amino acid sequences of other glucosyltransferases in plants.

Abstract
INTRODUCTION Patients with mitral valve disease frequently have atrial fibrillation (AF), and the left atrium is presumed to be the primary atrium that develops AF. However, it is still not clear whether the electrophysiologic abnormalities responsible for AF are confined to the left atrium in this subset of patients. METHODS AND RESULTS To examine the AF vulnerability of each atrium, we measured the wavelength and inhomogeneity of the conduction at the lateral right atrium, lateral left atrium, and Bachmann's bundle after defibrillation of AF in seven patients undergoing the maze procedure and mitral valve surgery for AF and isolated mitral valve disease, respectively (AF group). The data were compared with five coronary surgery patients in sinus rhythm (SR group). The wavelength in the AF group was significantly shorter (P < 0.05) than in the SR group not only at the lateral left atrium (225 +/- 62 vs 285 +/- 36 mm) but also at the lateral right atrium (214 +/- 54 vs 254 +/- 34 mm). The variation coefficient of the local maximum activation phase difference in the AF group (1.9 +/- 0.8 at the right atrium, 2.1 +/- 0.8 at the lateral left atrium, and 2.0 +/- 0.6 at Bachmann's bundle) was significantly greater (P < 0.05) than in the SR group at all atrial regions. CONCLUSION AF vulnerability was not confined to the left atrium immediately after defibrillation in AF patients with isolated mitral valve disease. Electrical remodeling resulting from perpetuation of AF, pathological changes extending to the right atrium, geometric changes caused by the atrial interactions occurring across the interatrial septum, or a combination of these may explain the results.

Abstract
A 39-year-old woman with fever of unknown origin was admitted to our hospital. Whole body scintigrams with 67Ga-citrate showed an abnormal accumulation of radioactivity in the pelvic cavity. Cystadenocarcinoma of the ovary was suspected on the basis of findings obtained by abdominal computed tomography and magnetic resonance imaging. Left oophorectomy was performed, and oophoritis was diagnosed. We would like to propose that 67Ga-citrate scintigraphy may be useful for the diagnosis of oophoritis as well as gynecologic malignant tumors.

Abstract
Clinical receptology encompasses broad areas, including receptor or postreceptor defects due to mutations of receptor or other genes, abnormalities due to receptor antibodies and secondary changes of receptors under various pathological conditions. Recent progress in molecular biology has succeeded in cloning genes of receptors, G-proteins and other cellular proteins that are involved in the signal transduction and clarified their germ-line and somatic mutations. It is of importance that mutations of receptors and G-proteins do not necessarily cause loss of function but sometimes cause gain of function of receptors or G-proteins, thus leading to hyperfunction. Molecular basis that causes either loss or gain of function has been studied but is not completely understood. Some examples of gain of function mutatious of G-protein coupled receptors, tyrosin kinase-type receptors and G alpha protein are shown. Another important aspect in receptor research is that mutation of a single receptor gene sometimes result in different phenotypes and even different modes of inheritance. For example, mutations of rhodopsin (a G-protein coupled receptor) gene cause retinitis pigmentosa of autosomal dominant type and autosomal recessive type and also cause congenital stationary night blindness. Exact mechanisms responsible for such differences are not completely understood. There are polymorphisms in some genes that may be involved in some diseases. An example is a polymorphism in beta 3-adrenergic receptor that is claimed but not clearly demonstrated to be a cause of obesity or type II diabetes. Such polymorphism is possibly a gene in polygenic diseases. Receptology is important for elucidating pathogenesis of complex diseases.
