2000 Okajimas Folia Anatomica Japonica  
The aim of the present study is to analyse unmyelinated nerve fibres of the human lesser splanchnic nerve in relation to the ageing process. With the help of an image-analyser, we examined 30 human lesser splanchnic nerves. The analysis was conducted with the use of a new staining method that makes it possible to discriminate various structures of the nervous tissue. Our report provides for the first time information on the ageing process of the human lesser splanchnic nerve fibres. The results

The aim of this study was to investigate the current status of doctor s delay in diagnosing endobronchial tuberculosis (EBTB) and to elucidate the risk factors contributing to the delay. [Methods] Retrospective clinicopathological analysis. [Patients] Sixty-two patients with EBTB were admitted at our hospital between 1999 and 2010. Their backgrounds, symptoms, diagnoses at initial consultation, delay in diagnosis, and clinical examination results were analyzed. [Results] Of the 62 patients, 59

Among the 40 patients with total diagnostic delay of more than 2 months, only 11 experienced long patient s delay exceeding 2 months. However, 22 patients experienced long doctor s delay of more than 2 months (28% vs. 55%, respectively, p<0.05), suggesting that doctor s delay contributes more to total delay than patient s delay. Fever was less frequent in patients with long doctor s delays than in those without (0% vs. 18%, respectively), at the initial consultation. In addition, radiographs showed that patients with long doctor s delays more frequently presented with shadows in the lower lung fi eld (50% vs. 23%, p<0.05), and most of these patients had noncavitary shadows on admission. All 7 patients diagnosed with bronchial asthma at the initial consultation had long doctor s delays. [Conclusion] These fi ndings demonstrate that long doctor s delays in diagnosing EBTB remain an issue. The clinical features of EBTB with long doctor s delays were confi rmed to be quite different from those of pulmonary tuberculosis.

2011 Nucleic Acids Research  
Non-coding RNAs (ncRNAs) play key roles in diverse cellular activities, and efficient ncRNA function requires extensive posttranscriptional nucleotide modifications. Small nucleolar RNAs (snoRNAs) are a group of ncRNAs that guide the modification of specific nucleotides in ribosomal RNAs (rRNAs) and small nuclear RNAs. To investigate the physiological relevance of rRNA modification in vertebrates, we suppressed the expression of three snoRNAs (U26, U44 and U78), either by disrupting the host

Using a highly sensitive mass spectrometric analysis, we found that decreased snoRNA expression reduces the snoRNA-guided methylation of the target nucleotides. Impaired rRNA modification, even at a single site, led to severe morphological defects and embryonic lethality in zebrafish, which suggests that rRNA modifications play an essential role in vertebrate development. This study highlights the importance of posttranscriptional modifications and their role in ncRNA function in higher eukaryotes.

Bound Substrate in the Structure of Cyanobacterial Branching Enzyme Supports a New Mechanistic Model

Mari Hayashi, Ryuichiro Suzuki, Christophe Colleoni, Steven G. Ball, Naoko Fujita, Eiji Suzuki
2017 Journal of Biological Chemistry  
Edited by Norma Allewell Branching enzyme (BE) catalyzes the formation of ␣-1,6-glucosidic linkages in amylopectin and glycogen. The reaction products are variable, depending on the organism sources, and the mechanistic basis for these different outcomes is unclear. Although most cyanobacteria have only one BE isoform belonging to glycoside hydrolase family 13, Cyanothece sp. ATCC 51142 has three isoforms (BE1, BE2, and BE3) with distinct enzymatic properties, suggesting that investigations of
more » ... hese enzymes might provide unique insights into this system. Here, we report the crystal structure of ligand-free wild-type BE1 (residues 5-759 of 1-773) at 1. Å resolution. The enzyme consists of four domains, including domain N, carbohydrate-binding module family 48 (CBM48), domain A containing the catalytic site, and domain C. The central domain A displays a (␤/␣) 8barrel fold, whereas the other domains adopt ␤-sandwich folds. Domain N was found in a new location at the back of the protein, forming hydrogen bonds and hydrophobic interactions with CBM48 and domain A. Site-directed mutational analysis identified a mutant (W610N) that bound maltoheptaose with sufficient affinity to enable structure determination at 2.30 Å resolution. In this structure, maltoheptaose was bound in the active site cleft, allowing us to assign subsites ؊7 to ؊1. Moreover, seven oligosaccharide-binding sites were identified on the protein surface, and we postulated that two of these in domain A served as the entrance and exit of the donor/acceptor glucan chains, respectively. Based on these structures, we propose a substrate binding model explaining the mechanism of glycosylation/deglycosylation reactions catalyzed by BE.

2015 Acta Crystallographica Section F Structural Biology Communications  
Several cyanobacterial species, includingCyanothecesp. ATCC 51142, remarkably have four isoforms of α-glucan branching enzymes (BEs). Based on their primary structures, they are classified into glycoside hydrolase (GH) family 13 (BE1, BE2 and BE3) or family 57 (GH57 BE). In the present study, GH13-type BEs fromCyanothecesp. ATCC 51142 (BE1, BE2 and BE3) have been overexpressed inEscherichia coliand biochemically characterized. The recombinant BE1 was crystallized by the hanging-drop

The crystals belonged to the tetragonal space groupP41212, with unit-cell parametersa = b = 133.75,c= 185.90 Å, and diffracted to beyond 1.85 Å resolution. Matthews coefficient calculations suggested that the crystals of BE1 contained two molecules in the asymmetric unit.

2009 Fukushima Journal of Medical Science  
It is well known that unilateral profound sensorineural hearing loss is caused by mumps; however, bilateral deafness is rare. Herein we report a case of bilateral profound hearing loss caused by mumps infection in a four-year-old boy. Labyrinthitis due to the mumps virus was suspected. His verbal understanding was poor, and he completely stopped talking. He was soon fitted with a hearing aid, but it proved insufficient. Thereupon, cochlear implantation was performed on his left ear. Six months

In cases of bilateral profound hearing loss due to mumps infection conservative therapy is ineffective; therefore, cochlear implantation is recommended. Vaccine coverage for mumps virus is also strongly recommended in Japan.

2008 Chemical and pharmaceutical bulletin  
A formulation study of intravesical oxybutynin (OB) preparations was carried out in order to improve the effectiveness in intravesical instillation therapy for spastic neurogenetic bladder. Sodium hyaluronate (HYA) was introduced to enhance the muco-adhesiveness of the instillation preparation, and the physicochemical properties of the OB formulation were evaluated in comparison with a conventional formulation containing hydroxypropylcellulose (HPC).

HYA was able to enhance the intravesical retention properties of OB instillation solution to a lesser degree than HPC, it seemed to be a useful additive in the OB instillation due to its safety and mucosal-protective effect.
