ヘパリンおよびヘパラン硫酸 (HS) は、複雑な骨格を持つ多糖であり、多くのタンパク質の活性を媒介・調節している。それらのタンパク質は、多様な硫酸化パターンで修飾された繰返し2糖骨格を持つ糖鎖と相互作用する。相互作用に関する分子レベルの詳細な知見は、新しい形態の診断薬や治療薬の開発に役立つと期待される。ヘパリンおよびHS骨格オリゴ糖の化学合成は、構造活性相関研究のための構造が明確な試料の入手を容易とするため、非常に重要である。しかしながら、化学合成においてもいくつかの課題に直面することが多い。いくつかの課題とは、例えば、希少なL-イドース/L-イズロン酸誘導体の入手、グルコサミンのグリコシル化反応におけるα-立体選択性、糖鎖の伸長法、位置選択的な硫酸基の導入を含む保護基の選択とその取り扱い、天然のヘパリンおよびHS鎖に相当する充分な多様性を持った化合物群の効率的な調製である。本総説は上記の課題に取り組んだ私達の成果に焦点をおきながら、これまで研究されてきた解決策を簡潔にまとめる。さらに、合成した糖鎖を用いた生物学的アッセイの結果についても簡単に述べる。

Effects of initial pH (3–12) on mesophilic hydrolysis and acidification reactions of swine manure was studied. The initial pH changed the microbial community in the suspension so as to affect hydrolysis and acidification reactions on swine manure. At pH 10–12 the Clostridium alkalicellum and/or Corynebacterium humireducens were enriched and the soluble chemical oxygen demand (SCOD), total volatile fatty acids (VFAs), proteins and carbohydrates from manure were increased in quantities. In particular, at pH 10 the VFA concentration peaked at 13,600 mg-COD/L, with acetate and propionate accounting for 71.8% of the total VFAs. Acidic environment facilitates release of ammonium from manure. The Butyricimonas sp. was found existing at initial pH 5 which led to accumulated quantities of butyrate. Initial pH adjustment was revealed to be an effective way to manipulate rates and end products of hydrolysis and acidification of swine manure.

Central corneal thickness (CCT) can be a promising source of glaucoma monitoring and diagnosis. This study evaluated changes to CCT according to experimental adjustment of intraocular pressure (IOP) in canine eyes. To adjust and measure IOP, each eye was cannulated with two 26-gauge needles under inhalant anesthesia. One needle was connected to a pressure transducer and the other to an adjustable bag of physiologic saline. IOP was stepwise increase from 10 mmHg to 70 mmHg in 10 mmHg increments (Group T). IOP was maintained at 15 mmHg (Group C15), 30 mmHg (Group C30), 45 mmHg (Group C45), 60 mmHg (Group C60) and 75 mmHg (Group C75) during the experiment. CCT was measured with an ultrasonic pachymeter every 10 mins after the cannulation. There was a significant difference in effect of the time on CCT (P<0.001) and difference in CCT (dCCT; P<0.001) between groups. The CCT of group C15 remained constant during the experiment. However, groups T showed an initial decrease and then an increase after passing a lowest point. Group C30 showed decreasing values for 30 mins, after which values remained constant. Group C45 was not changed for 40 min and then increased. Group C60 was not changed for 20 min and then increased. Group C75 showed a steady increase. In conclusion, the CCT showed two core changes according to increased IOP. This study provides essential basic data to enable further investigation into the association of IOP and CCT in dogs.

Objectives: Pushing tasks are functional activities of daily living. However, shoulder complaints exist among workers exposed to regular pushing conditions. It is crucial to investigate the control of shoulder girdles during pushing tasks. The objective of the study was to demonstrate scapular muscle activities and motions on the dominant side during pushing tasks and the relationship between scapular kinematics and muscle activities in different pushing conditions. Methods: Thirty healthy adults were recruited to push a four-wheel cart in six pushing conditions. The electromyographic signals of the upper trapezius (UT) and serratus anterior (SA) muscles were recorded. A video-based system was used for measuring the movement of the shoulder girdle and scapular kinematics. Differences in scapular kinematics and muscle activities due to the effects of handle heights and weights of the cart were analyzed using two-way ANOVA with repeated measures. The relationships between scapular kinematics and muscle activities were examined by Pearson’s correlation coefficients. Results: The changes in upper trapezius and serratus anterior muscle activities increased significantly with increased pushing weights in the one-step pushing phase. The UT/SA ratio on the dominant side decreases significantly with increased handle heights in the one-step pushing phase. The changes in upward rotation, lateral slide and elevation of the scapula decreased with increased pushing loads in the trunk-forward pushing phase. Conclusions: This study indicated that increased pushing loads result in decreased motions of upward rotation, lateral slide and elevation of the scapula; decreased handle heights result in relatively increased activities of the serratus anterior muscles during pushing tasks.

An 8-year-old male mongrel dog that had undergone renal transplantation was presented 25 days later with an acute cough, anorexia and exercise intolerance. During the investigation, neutrophilic leukocytosis was noted, and thoracic radiographs revealed caudal lung lobe infiltration. While being treated with two broad-spectrum antibiotics, clinical signs worsened. Pneumonia due to infection with multidrug-resistant (MDR) Pseudomonas (P.) aeruginosa, sensitive only to imipenem and amikacin, was confirmed by bacteria isolation. After treatment with imipenem-cilastatin without reducing the immunosuppressant dose, clinical signs completely resolved. During the 2-year follow-up period, no recurrence was observed. To the best of authors’ knowledge, this is the first report of pneumonia caused by MDR P. aeruginosa in a renal recipient dog and successful management of this disease.

Background: Gastric cancer, the most common cancer in the world, is affected by some foods or food groups. We examined the relationship between dietary intake and stomach cancer risk in the Korean Multi-Center Cancer Cohort (KMCC).Methods: The KMCC included 19 688 Korean men and women who were enrolled from 1993 to 2004. Of those subjects, 9724 completed a brief 14-food frequency questionnaire at baseline. Through record linkage with the Korean Central Cancer Registry and National Death Certificate databases, we documented 166 gastric cancer cases as of December 31, 2008. Cox proportional hazard models were used to estimate relative risks (RRs) and 95% CIs.Results: Frequent intake of soybean/tofu was significantly associated with reduced risk of gastric cancer, after adjustment for age, sex, cigarette smoking, body mass index, alcohol consumption, and area of residence (P for trend = 0.036). We found a significant inverse association between soybean/tofu intake and gastric cancer risk among women (RR = 0.41, 95% CI: 0.22–0.78). Men with a high soybean/tofu intake had a lower risk of gastric cancer, but the reduction was not statistically significant (RR = 0.77, 95% CI: 0.52–1.13). There was no interaction between soybean/tofu intake and cigarette smoking in relation to gastric cancer risk (P for interaction = 0.268).Conclusions: Frequent soybean/tofu intake was associated with lower risk of gastric cancer.

BackgroundWhile β-blockers can be effective in controlling tachyarrhythmias after pediatric cardiac surgery, a negative inotropic influence sometimes complicates their use. Landiolol hydrochloride is a novel, ultra-short-acting β-blocker recently developed in Japan. The drug has higher β1:β2 selectivity ratio and a less negative inotropic effect. This study retrospectively evaluates the efficacy and safety of landiolol in the management of tachyarrhythmias after pediatric cardiac surgery.MethodsA retrospective analysis was performed on 312 consecutive patients undergoing surgery for congenital heart disease. Twelve patients were treated with landiolol for critical tachyarrhythmia. The mean age of patients was 28.7 ± 10.6 months. Five junctional ectopic tachycardia, 2 atrial flutters, 1 paroxysmal supraventricular tachycardia, 1 atrial fibrillation, 1 atrioventricular reciprocating tachycardia with Wolff-Parkinson-White syndrome and 2 excessive sinus tachycardia were treated.ResultsThe mean loading and maintenance doses were 11.3 ± 4.0 and 6.8 ± 0.9 μg/kg per minute, respectively. Rate control was achieved in all patients. Landiolol reduced the heart rate from 169.7 ± 11.4 to 127.7 ± 7.5 beats per minute (p < 0.05) while blood pressure did not significantly change. Tachyarrhythmias were converted to sinus rhythm in 70.0% of the cases and the average time needed to achieve heart rate reduction was 2.3 ± 0.5 hours.ConclusionsLandiolol was efficacious in treating tachyarrhythmia in pediatric cardiac surgery. The desired negative chronotropic effect was achieved without significant hemodynamic compromise. The ultra-short half-life of landiolol provided rapid dose manipulation. This study suggests that landiolol is a promising option for the management of postoperative tachyarrhythmias in pediatric patients.

Canine degenerative myelopathy is an adult-onset, progressive neurodegenerative disease that occurs in multiple dog breeds, particularly Pembroke Welsh Corgis. Recently, a degenerative myelopathy-associated mutation of the canine SOD1 gene was identified as c.118G>A (p.E40K). In the present study, genotyping assays using conventional and real-time PCR methods were developed, and a preliminary genotyping survey was performed on 122 randomly selected Pembroke Welsh Corgis without any degenerative myelopathy-related clinical signs to determine the current allele frequency in Japan. Both of the assays provided clear-cut genotyping. The survey demonstrated the frequencies of the G/G wild-type, G/A heterozygote and A/A homozygote to be 9.0, 42.6 and 48.4%, respectively, indicating that the prevalence of the mutant A allele (69.7%) in Pembroke Welsh Corgis is extremely high in Japan.

The p16, p15 and p14 genes are widely known as tumor suppressor genes in human medicine. Although a large number of genetic and epigenetic aberrations in these genes have been reported in human malignancies, canine malignancies have not been well analyzed on the aberrations of these genes. In this study, the full-length complementary DNA (cDNA) of the canine p16 gene was cloned using the 5’ and 3’ rapid amplification of cDNA ends methods. Based on the sequence data, primers specific for p16, p15 and p14 were designed. Using these primers, the expression of p16, p15 and p14 mRNAs could be individually evaluated by reverse transcriptase polymerase chain reaction. Genomic aberrations were also examined using genomic polymerase chain reaction. Two of the 6 canine lymphoid tumor cell lines did not express detectable levels of p16, p15 and p14 mRNAs, and wide-ranging deletions in the p15-p14-p16 genomic locus were suspected. Wide-ranging deletions were also speculated in 2 of 14 dogs with T-cell lymphoid tumors. On the other hand, similar failure of amplification suggesting wide-ranging deletions were not observed in any of the 14 dogs with B-cell lymphoma. Deletion of the p15-p14-p16 genomic locus could be one of the molecular aberrations in canine lymphoid tumor cells.

In this study, we aimed to determine the effect of trehalose coating and the optimal dose of basic fibroblast growth factor (bFGF), an osteoinductive protein, loaded onto tailor-made bone implants for implant-induced bone formation in vivo. We fabricated tailor-made α-tricalcium phosphate bone implants (11 mm diameter with 2 parallel cylindrical holes). bFGF 0, 1, 10, 100 or 200 μg/implant was incorporated into implants with and without a trehalose coating, and these were subsequently implanted into dogs to correct temporal bone defects of the same size and shape. Four weeks after implantation, we analyzed the bone implants and surrounding tissues by using micro-computed tomography imaging and histological analyses, as well as gross evaluation. No significant difference in new bone formation was observed between implants with and without a trehalose coating at any of the bFGF doses. Bone implants with 100 and 200 μg bFGF showed significantly more new bone formation at the implant site and within the cylindrical holes of the implants than those without bFGF (Pin vivo, probably due to the presence of blood proteins and electrolytes at the implant site.

Lymphoid malignancies, such as leukemia, and many types of lymphoma are common and severe disorders in dogs. Since shortening remission duration caused by resistance to chemotherapy often becomes clinically critical problems, development of novel and effective therapy should be required. The present study investigated the status of NF-κB and effect of its inhibitor, bortezomib, in six canine neoplastic lymphoid cell lines. NF-κB p65 and p50 were detected in the nuclear fraction of GL-1, CLBL-1 and CL-1, suggesting that NF-κB was constitutively activated in the cells. NF-κB p65 was detected in the cytoplasmic fraction of UL-1 and Ema. After incubation with bortezomib, NF-κB p50 and p65 became undetectable in the nuclear fraction of GL-1, CLBL-1 and CL-1, and CLBL-1, respectively, and p65 was clearly degraded in the cytoplasmic fraction of CLBL-1 and CL-1. Bortezomib inhibited the proliferation of all cell lines except Nody-1 in a concentration-dependent manner. The results indicated that constitutive activation of NF-κB could contribute to the proliferation of canine neoplastic lymphoid cells, and bortezomib would have suppressive effects on the NF-κB activation and the proliferation of neoplastic lymphoid cells in dogs.

Short-chain-length medium-chain-length polyhydroxyalkanoate (SCL-MCL PHA) copolymers are promising as bio-plastics with properties ranging from thermoplastics to elastomers. In this study, the hybrid pathway for the biosynthesis of SCL-MCL PHA copolymers was established in recombinant Escherichia coli by co-expression of β-ketothiolase (PhaARe) and NADPH-dependent acetoacetyl-CoA reductase (PhaBRe) from Ralstonia eutropha together with PHA synthases from R. eutropha (PhaCRe), Aeromonas hydrophila (PhaCAh), and Pseudomonas putida (PhaC2Pp) and with (R)-specific enoyl-CoA hydratases from P. putida (PhaJ1Pp and PhaJ4Pp), and A. hydrophila (PhaJAh). When glycerol supplemented with dodecanoate was used as primary carbon source, E. coli harboring various combinations of PhaABCJ produced SCL-MCL PHA copolymers of various monomer compositions varying from C4 to C10. In addition, polymer property analysis suggested that the copolymers produced from this recombinant source have thermal properties (lower glass transition and melting temperatures) superior to polyhydroxybutyrate homopolymer.

Patent network analysis, an advanced method of patent analysis, is a useful tool for technology management. This method visually displays all the relationships among the patents and enables the analysts to intuitively comprehend the overview of a set of patents in the field of the technology being studied. Although patent network analysis possesses relative advantages different from traditional methods of patent analysis, it is subject to several crucial limitations. To overcome the drawbacks of the current method, this study proposes a novel patent analysis method, called the intelligent patent network analysis method, to make a visual network with great precision. Based on artificial intelligence techniques, the proposed method provides an automated procedure for searching patent documents, extracting patent keywords, and determining the weight of each patent keyword in order to generate a sophisticated visualization of the patent network. This study proposes a detailed procedure for generating an intelligent patent network that is helpful for improving the efficiency and quality of patent analysis. Furthermore, patents in the field of Carbon Nanotube Backlight Unit (CNT-BLU) were analyzed to verify the utility of the proposed method.

Inference of subcellular location only using sequence information is important. In this paper, we proposed the application of principal component analysis-based linear discriminant analysis for subcellular location information. It achieved the performance of Area Under the Curve under Receiver Operating Characteristic curve mostly more than 0.95 if less than 80% sequence identity non-redundancy was applied.
