PURPOSE The purpose of this study was to discriminate supratentorial intraventricular subependymoma (SIS) from central neurocytoma (CNC) using magnetic resonance spectroscopy (MRS). METHODS Single-voxel proton MRS using a 1.5T or 3T MR scanner from five SISs, five CNCs, and normal controls were evaluated. They were examined using a point-resolved spectroscopy. Automatically calculated ratios ...

BACKGROUND Recently, healing of a ruptured anterior cruciate ligament (ACL) is reconsidered. In a previous study, we have shown that the transected ACL can heal after treatment with the triple X locking suture alone or combined with small intestine submucosa (SIS). The first research question of this study was whether the healing ACLs in both groups show histological characteristics that are ty...

Second impact syndrome (SIS) occurs when a person sustains a second brain injury before the symptoms of an initial brain injury resolve [1,2]. Severe brain edema develops due to cerebral vasculature dysautoregulation and causes significant neurologic deficits [1-3]. SIS is a rare condition that occurs primarily in adolescents and young adults. Severe neurologic deficits and death typically occu...

The interrater reliability of the Supports Intensity Scale (SIS) was investigated under the condition that interviewers had to have been trained and/or experienced in its administration and scoring. Both corrected and noncorrected Pearson's product-moment coefficients were generated to assess interinterviewer, interrespondent, and mixed interrater reliability. The correlation coefficients for t...

The paulomycins are a group of glycosylated compounds featuring a unique paulic acid moiety. To locate their biosynthetic gene clusters, the genomes of two paulomycin producers, Streptomyces paulus NRRL 8115 and Streptomyces sp. YN86, were sequenced. The paulomycin biosynthetic gene clusters were defined by comparative analyses of the two genomes together with the genome of the third paulomycin...

Streptomyces albus is the type species of the genus Streptomyces. Here, we report the draft genome sequence of S. albus strain NBRC 13014(T). The genome contains at least seven orphan polyketide synthase and nonribosomal peptide synthetase gene clusters. The genome sequence will also serve as a valuable reference for Streptomyces taxonomy.

It has long been thought that the life cycle of Streptomyces bacteria encompasses three developmental stages: vegetative hyphae, aerial hyphae and spores. Here, we show interactions between Streptomyces and fungi trigger a previously unobserved mode of Streptomyces development. We term these Streptomyces cells 'explorers', for their ability to adopt a non-branching vegetative hyphal conformatio...

The purpose of this study was to compare: a new five-layered poly (L-lactide-co-caprolactone) (PLC) membrane and small intestinal submucosa (SIS) as a control in rat urinary bladder wall regeneration. The five-layered poly (L-lactide-co-caprolactone) membrane was prepared by an electrospinning process. Adipose tissue was harvested from five 8-week old male Wistar rats. Adipose derived stem cell...

The v-sis gene is able to transform cells by production of a growth factor that is structurally related to platelet-derived growth factor. This growth factor has been detected in the conditioned media of v-sis transformed cells, and is able to stimulate the autophosphorylation of the platelet-derived growth factor receptor. We have used the v-sis gene product to analyze the role of protein-enco...

Small intestinal submucosa (SIS) has been successfully used to treat a variety of damaged or diseased tissues in human patients. As a biologic scaffold, SIS stimulates repair of damaged or diseased tissues and organs with tissue that is similar in structure and function to the material it was meant to replace. To meet clinical safety requirements, biologic materials from animal tissues must und...
