Abstract
BACKGROUND Emerging evidence suggests that stemness in cancer cells is a cause of drug resistance or metastasis and is an important therapeutic target. PR [positive regulatory domain I-binding factor 1 (PRDI-BF1) and retinoblastoma protein-interacting zinc finger gene (RIZ1)] domain containing 14 (PRDM14), that regulates pluripotency in primordial germ cell, has reported the overexpression and function of stemness in various malignancies, suggesting it as the possible therapeutic target. However, to our knowledge, there have been no reports on the expression and function of PRDM14 in colorectal cancer (CRC). Therefore, we investigated the expression and the role of PRDM14 in CRC. METHODS We performed immunohistochemistry evaluations and assessed PRDM14 expression on 414 primary CRC specimens. Colon cancer cell lines were subjected to functional and stemness assays in vitro and in vivo. RESULTS We found that PRDM14 positive staining exhibited heterogeneity in the CRC primary tumor, especially at the tumor invasion front. The aberrant expression of PRDM14 at the invasion front was associated with lymph node metastasis and disease stage in patients with CRC. Furthermore, the multivariate analysis revealed high PRDM14 expression as an independent prognostic factor in the patients with Stage III CRC. Overexpression of PRDM14 enhanced the invasive, drug-resistant and stem-like properties in colon cancer cells in vitro and tumorigenicity in vivo. CONCLUSION Our findings suggest that PRDM14 is involved in progression and chemoresistance of CRC, and is a potential prognostic biomarker and therapeutic target in the CRC patients.

Abstract
Gender-related risk factors in the survival of transplanted teeth with complete root formation have not yet been identified. The purpose of this study was to investigate gender differences in tooth autotransplantation at dental clinics. We asked participating dentists to provide information on transplantations they had undertaken from 1 January 1990 to 1931 December 2010. The data were screened to exclude patients who underwent more than one transplantation, smokers or those whose smoking habits were unknown, patients under 30 or who were 70 years old and over, cases where the transplanted teeth had incomplete root formation or multiple roots and those with fewer than 20 present teeth post-operation. We analysed 73 teeth of 73 males (mean age, 47.2 years) and 106 teeth of 106 females (mean age, 45.3 years) in this study. The cumulative survival rate and mean survival time were calculated using the Kaplan-Meier method. The cumulative survival rate for males was 88.3% at the 5-year mark, 64.8% at 10 years and 48.6% at 15 years; for females, it was 97.2% at the 5-year mark, 85.9% at 10 years and 85.9% at 15 years. A log-rank test indicated the difference between males and females to be significant (P = 0.011). There was also a significant difference in the main causes for the loss of transplanted teeth: males lost more transplanted teeth due to attachment loss than females (P < 0.05). These results indicate that males require more attention during the autotransplantation process, particularly at the stage of pre-operation evaluation and that of follow-up maintenance.

Abstract
The aim of this study was to investigate the risk factors affecting long-term prognosis of autotransplantation of third molars with complete root formation in males at dental clinics. Participating dentists were requested to provide information on transplantations they had undertaken from 1 January 1990 to 31 December 2010. Data on a total of 708 teeth from 637 patients were collected. After data screening and elimination, participants of this study consisted of 183 teeth of 171 males ranging from 20 to 72 years of age (mean age, 44·8 years). The cumulative survival rate was 86·0% at the 5-year mark, 59·1% at 10 years and 28·0% at 15 years. The mean survival time was 134·5 months, as calculated by the Kaplan-Meier method. Single factor analysis using the log-rank test showed that the following factors had significant influence (P < 0·05) on survival of transplanted teeth: periodontal disease as the reason for recipient site tooth extraction, fewer than 25 present teeth and Eichner index Groups B1 to C. Cox regression analysis examined five factors: age, smoking habit, recipient site extraction caused by periodontal disease, fewer than 25 present teeth and Eichner index. This analysis showed that two of these factors were significant: fewer than 25 present teeth was 2·63 (95% CI, 1·03-6·69) and recipient site extraction caused by periodontal disease was 3·80 (95% CI, 1·61-9·01). The results of this study suggest that long-term survival of transplanted teeth in males is influenced not only by oral bacterium but also by occlusal status.

Abstract
Formate dehydrogenases (FDH) are useful for the regeneration of NADH, which is required for asymmetric reduction by several dehydrogenases and reductases. FDHs have relatively low activity and are labile, especially to alpha-haloketones, thus FDH cannot be applied to the industrial manufacture of optically active alpha-haloalcohols. To stabilize a FDH from Mycobacterium vaccae (McFDH) against the alpha-haloketone ethyl 4-chloroacetoacetate (ECAA), a set of cysteine-mutant enzymes was constructed. Sensitivity to ECAA of mutant C6S was similar to that of the wild-type enzyme, and mutants C249S and C355S showed little activity. In contrast, mutant C256S exhibited remarkable tolerance to ECAA. Surprisingly, mutant C146S was activated by several organic compounds such as ethyl acetate. An optimized mutant, C6A/C146S/C256V (McFDH-26), was obtained by combining several effective mutations. Ethyl (S)-4-chloro-3-hydroxybutanoate [(S)-ECHB] was synthesized from ECAA to 49.9 g/l with an optical purity of more than 99% e.e. using recombinant Escherichia coli cells coexpressing McFDH-26 and a carbonyl reductase (KaCR1) from Kluyveromyces aestuarii.

Abstract
An experimental comparative histomorphological study was made on intestinal healing processes following an Albert-Lembert suture with approximation of the serosal surface and Gambee's layer to layer anastomosis of a dog. There was no obvious complications such as postoperative hemorrhage, anastomotic stenosis or anastomotic leakage. Although both anastomoses resulted in a good healing process, Gambee's layer to layer suture, which caused the submucosal layers to face each other, showed better wound healing at the anastomosis in terms of layer to layer attachment. As a conclusion, Gambee's layer to layer anastomosis seemed to be a better anastomotic technique in terms of wound healing for the intestinal anastomosis.

Abstract
A new lipase (OBase) which efficiently hydrolyzes oleyl benzoate (OB) was found in the culture supernatant of Acinetobacter nov. sp. strain KM109, a new isolate growing in a minimum medium containing OB as the sole carbon source. OBase was purified to homogeneity with 213-fold purification and 0.8% yield. The molecular weight was estimated to be 62,000 +/- 1,000 by SDS-PAGE under denatured-reduced conditions and to be 50,000 +/- 1,000 by gel-filtration HPLC under native conditions; these findings indicate that OBase is a monomeric enzyme. The optimum temperature and pH of OBase were about 45 degrees C and pH 8. Temperature and pH stabilities were at or lower than 35 degrees C and in a range of pH 6-8, respectively. Purified OBase preferentially hydrolyzed p-nitrophenyl benzoate (pNPB) over p-nitrophenyl acetate (pNPA) or p-nitrophenyl caproate (pNPC) [pNPB/pNPA = 20 and pNPB/pNPC = 5.4], indicating that OBase has a high affinity for benzoyl esters. Partial amino-acid sequences of OBase fragments obtained after lysyl endopeptidase treatment showed no similarity with known proteins.

Abstract
Although fibrin glue has been widely used as a surgical adhesive, its components, fibrinogen and thrombin, obtained from human blood are not completely free from the risk of virus infection due to acquired immune deficiency and hepatitis. Recently, we have reported that a polymer pair composed of gelatin and poly(L-glutamic acid) (PLGA) promptly forms a gel and can firmly bond to soft tissues when crosslinked with the aid of water-soluble carbodiimide (WSC). The present study was undertaken to design a new PLGA-gelatin glue without using WSC. Two kinds of PLGA with molecular weights of 71 and 22 kDa were employed to prepare N-hydroxysuccinimide (NHS) activated derivatives. The NHS-activated PLGA could be synthesized at high yields and was found to be stable for an extended time without losing the ability to crosslink with gelatin when stored under a dry-cold condition. This NHS-activated PLGA could spontaneously form a gel with gelatin in an aqueous solution within a short time, comparable to a commercial fibrin glue, when gelation was allowed to proceed at pH 8.3. The NHS-activated PLGA prepared from PLGA with the molecular weight of 22 kDa could be readily dissolved at high concentrations and its ability to form a gel was maintained for more than 10 min when an acidic 8% NHS-activated PLGA solution was used. The bonding strength of PLGA gelatin glues with natural tissue was higher than that of fibrin glue. These findings strongly suggest that this combination of gelatin and NHS-PLGA is very promising as a surgical adhesive and may possibly replace fibrin glues prepared from human blood components.

Abstract
It has long been believed that trypsin is normally synthesized only in the pancreas. In the present study, expression of trypsin in human and mouse nonpancreatic tissues was examined. Northern blot analysis of normal human tissues indicated that the trypsin gene is expressed at high levels in the pancreas and spleen and considerably in the small intestine. However, in situ hybridization and immunohistochemistry demonstrated that trypsin is widely expressed in epithelial cells of the skin, esophagus, stomach, small intestine, lung, kidney, liver, and extrahepatic bile duct, as well as splenic and neuronal cells. In the spleen, trypsin message was detected in macrophages, monocytes, and lymphocytes in the white pulp. In the brain, it was detected in the nerve cells of the hippocampus and cerebral cortex. Analysis by gelatin zymography confirmed the presence of a latent or an active form of trypsin in various normal mouse tissues. Reverse transcription-polymerase chain reaction analysis also confirmed the expression of trypsin genes in the spleen, liver, kidney, and brain of normal mice. Such a broad distribution of trypsin suggests its general roles in the maintenance of normal epithelial cell functions, the immune defense system, and the central nervous system.

Abstract
The authors present eight cases of reconstruction of the breasts using bilaterally divided TRAM flaps after removing the injected silicone gel and granulomas. In Japan, we have the opportunity to examine many patients who have had foreign substance injections to the breasts for purposes of augmentation however, most of them are now suffering from delayed complications. Until now we have reconstructed breasts such cases by use of silicone bag prostheses after removal of granulomas; however, now it is difficult to obtain silicone prostheses. Thus, we have decided to reconstruct by the use of autogenous cutaneous and adipose tissue flaps as presented by us in this article.

Abstract
Between 1988 and 1994, 110 patients with 139 so-called keloids site, which had been treated with conservative therapy were treated with excision, suture, and postoperative irradiation with a 4 MeV electron beam. They were irradiated within one or two days after surgery, for three consecutive days. The total doses were 15 Gy or 18 Gy per fractions for the most part. Control rates of true keloids and hypertrophic scars were 76.0% (57/75) and 93.8% (60/64), respectively, and the overall effectiveness rate was 84.2%. No remarkable side effects were observed. Transient hyperpigmentation was found in 44.6%. No carcinogenesis have been found in our series of patients. Considering the possibility of recurrence, side effects, and carcinogenesis, the indication of our treatment was decided. The result of our treatment using a low-megavolt electron beam was similar to that of published series using a low-energy X-ray. The advantages of the use of electron beam are that the peak of dose is the layer of the occurrence of keloid, and that the depth of penetration of radiation is limited without appreciable effect on the deeper structures. At present, the equipments of low-energy X-ray have been disposed. Our treatment using a electron beam will be an effective treatment.

Abstract
Clinical efficacy of combination therapy using Fortimicin (ASTM) and Cefotax (CTX) was studied in 63 patients with complicated urinary tract infections. The patients received 200 mg of ASTM i.m. and 1 g of CTX i.v. twice a day. The overall clinical efficacy of the treatment was evaluated by criteria proposed by the Japanese UTI Committee. The overall clinical efficacy rate was 68.3%. The rate was 67.3% in the patients with single bacterial infection and 72.7% in those with mixed infections. Subjective side effects were observed in one of the patients. Drug related aggravation in laboratory tests was observed in 8 items in 8 patients, but these were mild changes. We concluded that combination therapy with ASTM and CTX was useful for the treatment of complicated urinary tract infections.

Abstract
Fifty-two cases of renal cell carcinoma (cases with metastatic episode during follow-up period excluded) operated on and whose pathohistological staging had been established at our department clinic during a period of 11 years from January 1973 to December 1983 were studied. Renal arteriography i.e., selective renal arteriography, aortography, was performed on 49 cases, and CT scan and ultrasonic examination were performed on 19 and 15 cases, respectively for analytical comparison of the preoperative staging with the postoperative staging as based on the operative or pathological findings (Robson et al.). Staging was found correct in 33 of the 49 cases (67.3%) by arteriography and 16 of the 19 cases (84.2%) by CT scan. In the current study, ultrasonic assessment was possible only in those cases of venous infiltrations i.e., tumor embolism affecting the renal vein or the vena cava inferior. Most effective in the cases with extracapsular infiltrations or localized lymph node metastases was the CT scan. Correct diagnosis was also possible in 6 of the 8 cases (75%) with venous infiltrations if the arteriograms had been analysed in detail, and both the CT scan and the ultrasonic examination proved effective in this type of cases as well. These findings may suggest that the CT scan alone is sufficient for making a localized staging.

Abstract
Urinary arylsulfatase A activity expressed as units/mg of urinary creatinine was significantly increased in bladder cancer patients, but not in patients with other genitourinary tract disorders, such as cystitis, urethritis and prostatic cancer, nor in patients with non-urological malignant diseases. The urinary enzyme activity was positively correlated with the stage of the bladder cancer, while post surgical follow-up revealed a marked decrease of the activity. Arylsulfatase A activity was also shown to be higher in malignant than in normal bladder tissue, demonstrating the activity to be a function of the grade of the tumor. Furthermore, the isoelectric point (pI 5.2-5.3) of the tissue enzyme in the bladder tumor coincided with that of the urine enzyme from the same cancer patients; the pI of the enzyme in urine from normal subjects was 4.7. These results suggest that most of the urinary arylsulfatase A in bladder cancer originates from tumor tissue.

Abstract
A variant form of urinary arylsulfatase A which was not detected in normal voided urine was demonstrated in the urine obtained directly from the renal-pelvis [Ishibashi, T. et al.: Biochim. Biophys. Acta, 616, 218-227 (1980)]. The variant form was not observed in urine collected directly from the ureter during operations for uretero-cutaneostomy or ileal conduit. However, the urine from intubated uretero-cutaneostomy patients collected near the pelvi-ureteric junction showed the presence of the variant form, further suggesting the origin specificity of the variant. This arylsulfatase was not demonstrated in the voided urine from patients with non-urologic malignant disorders such as uterine endometrial, uterine cervical, rectal, pancreas head and gastric carcinomas, in spite of its appearance in high levels in the urine from patients with advanced bladder cancer.

Abstract
The prophylactic and chemotherapeutic efficacy of PMPC against infections after TUR-P has been investigated. Bacteriological evaluation: PMPC , 200-300 mg/day for 2-12 weeks, was administered to 49 patients, who had over 10(3)CFU/ml of microorganisms after CET or CEC treatment for 3-7 days. The eradication rate of microorganisms was 40.8% after 2 weeks, 52.2% after 4 weeks, 64.1% after 6 weeks, 65.0% after 8 weeks and 70.6% after 12 weeks. Effectiveness on pyuria : The improvement rate of pyuria against 59 patients who had over 10(5)/hpf of pyuria , was 15.3% after 2 weeks, 16.4% after 4 weeks, 25.4% after 6 weeks, 58.5% after 8 weeks, 72.7% after 10 weeks and 75.0% after 12 weeks. Overall clinical efficacy on PMPC was examined in 26 patients. The results of efficacy were 27.3% after 2 weeks, 48.0% after 4 weeks, 50.0% after 6 weeks, 69.2% after 8 weeks, 75.0% after 10 weeks and 77.0% after 12 weeks. The clinical response was evaluated according to a criterion for clinical evaluation of antimicrobial agent on chronic complicated UTI proposed by UTI committee in Japan. No severe adverse effect including allergic reaction was found. Following administration of PMPC , three patients experienced adverse gastric reactions, and drug administration was discontinued at week 6 or 8. PMPC was effective as a prophylactic chemotherapeutic drug against infections after TUR-P and prostatectomy.

Abstract
A 48-year-old male, who had been suffering from eosinophilic lymphfolliculosis of the skin (Kimura's disease) for six years, developed the nephrotic syndrome. Renal biopsy revealed immunopathological and electron microscopic changes characteristic of membranous glomerulonephritis. A review of the literature disclosed a high frequency of renal involvement in Kimura's disease. Out of 175 reported cases of the disease, 21 (12%) were found to have proteinuria including 13 who had the nephrotic syndrome. Some of the patients were noticed to have proteinuria before the onset of the skin lesions, suggesting the existence of common etiological factor(s) capable of inducing both skin and kidney lesions.

Abstract
10-Methoxy- (10) and 10-hydroxy-3-methyl-2,3,4,5,6,7-hexahydro-1H-3-benzazonine (11) have been synthesized from 7-methoxy-alpha-tetralone (1) via the 1-aminomethyl compound 4, which was converted to the amino acid derivative 7. Hydrogenation and cyclization of 7 afforded the lactam 9, which was reduced with LiAlH4, followed by N-methylation to give 10, from which 11 was obtained. Compounds 10 and 11 have analgetic activity, and the former was found to be comparable to codeine.
