BACKGROUND: The growing rod remains an effective option in the treatment of early-onset scoliosis, and has previously been likened to an internal brace. While details of growing-rod treatment have been largely agreed on, the appropriate end point remains a matter of controversy. A decision was made in 2004, at the beginning of growing-rod treatment at our institution, to remove longitudinal instrumentation when the period of lengthening concluded and, similar to discontinuing a brace, leave the spine free...

A novel strain, DKC-1T, was isolated from reclaimed grassland soil and was characterized taxonomically by a polyphasic approach. Strain DKC-1T was a Gram-staining-negative, light-yellow-coloured and rod shaped bacterium, motile with polar flagellum. It was able to grow at 20-37 °C, at pH 4.5-9.0 and with 0-3 % (w/v) NaCl concentration. Based on the 16S rRNA gene sequence analysis, strain DKC-1T formed a clade within the members of the genus Dyella and showed highest sequence similarities to Dyella japonica XD53T (98...

Gram-negative, spiral or curved rod-shaped cells of a bacterial strain, designated ZC80T, were isolated from a rock salt sample collected at Yunnan salt mine, China. Analysis of the strain's 16S rRNA gene sequence revealed a clear affiliation of this novel strain within the family Rhodospirillaceae. Strain ZC80T formed a robust cluster with Pelagibius litoralis CL-UU02T at a 16S rRNA gene sequence similarity level of 88.1 %. Strain ZC80T shared no more than 91.0 % 16S rRNA gene sequence similarity with the type strains of other species in the family Rhodospirillaceae...

Two Gram-stain-positive, rod-shaped and endospore-forming bacteria that represent a single species, designated strains KJ1-10-99T and KJ1-10-93, were isolated from a saline desert of Little Rann of Kutch, Gujarat, India. Analysis of 16S rRNA gene sequences revealed that the isolates belonged to the family Bacillaceae and were closely related to each other with 16S rRNA gene sequence similarity of 99.9 %. However, these two isolates formed a novel phylogenetic branch within this family. Both strains were aerobic, catalase and oxidase positive, and could grow optimally at 37 °C and pH 9...

A strain representing a rapidly growing, Gram-stain-positive, aerobic, rod-shaped, non-motile, non-sporulating and non-pigmented species of the genus Mycobacterium, designated strain S-I-6T, was isolated from groundwater at Daejeon in Korea. The strain grew at temperatures between 10 and 37 °C (optimal growth at 25 °C), between pH 4.0 and 9.0 (optimal growth at pH 7.0) and at salinities of 0-5 % (w/v) NaCl, growing optimally with 2 % (w/v) NaCl. Phylogenetic analyses based on multilocus sequence analysis of the 16S rRNAgene, hsp65, rpoB and the 16S-23S internal transcribed spacer indicated that strain S-I-6T belonged to the rapidly growing mycobacteria, being most closely related to Mycobacterium sphagni...

A Gram-positive, endospore-forming, strictly aerobic and rod-shaped bacterium, designated strain MME2_R6T, was isolated from Arctic soil, and it was identified by using a polyphasic taxonomic approach. This strain was psychrotolerant, growing at 4‒24 °C. 16S rRNA gene sequence analysis showed that strain MME2_R6T was closest to Paenibacillus swuensis DY6T, with 93.9 % similarity. However, in phylogenetic analysis based on the 16S rRNA gene sequence, strain MME2_R6T showed that it clustered with Paenibacillus contaminans CKOBP-6T and the sequencing similarity between the two species was 93...

Currently, commercial synthetic vascular grafts made from Dacron and ePTFE for small-diameter, vascular applications (<6 mm) show limited reendothelization and are less compliant, often resulting in thrombosis and intimal hyperplasia. Although good blood compatibility can be achieved in autologous arteries and veins, the number of high quality harvest sites is limited, and the grafts are size-mismatched for use in the fistula or cardiovascular bypass surgery; thus, alternative small graft substitutes must be developed...

A polyphasic approach was used to characterize an aerobic, Gram-negative, rod-shaped bacterium (designated strain CC-KL-3T) isolated from a hot spring. Phylogenetic analyses based on 16S rRNA genes indicated that strain CC-KL-3T showed highest sequence similarity to Hydrogenophaga bisanensis (97.7 %) and Hydrogenophaga atypica (97.6 %) and lower sequence similarity to other species (less than 97.6 %). The levels of DNA-DNA relatedness between strain CC-KL-3T, H. bisanensis and H. atypica were estimated to be 13...

Halophilic archaeal strain ZS-54-S2T was isolated from Zhoushan marine solar saltern, China. Cells were rod-shaped, Gram-stain-negative and formed red-pigmented colonies on an agar plate. Strain ZS-54-S2T was able to grow at 20-50 °C (optimum 35 °C), at 1.7-4.8 M NaCl (optimum 3.9 M), at 0.005-1.0 M MgCl2 (optimum 0.05 M) and at pH 5.0-9.5 (optimum pH 7.0). The cells lysed in distilled water and the minimal NaCl concentration to prevent cell lysis was found to be 5 % (w/v). The major polar lipids of the strain were phosphatidic acid, phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, two glycolipids, which were chromatographically identical to sulfated galactosyl mannosyl galactofuranosyl glucosyl diether and galactosyl mannosyl glucosyl diether, and an unidentified glycolipid, which was chromatographically identical to one detected in Halobacterium salinarum ATCC 33171T...

A psychrotolerant chitinolytic bacterium, designated NC1253T, was isolated from Zoige wetland on the Qinghai-Tibetan Plateau. This strain was a Gram-stain-positive, spore-forming and rod-shaped anaerobe. NC1253T grew at 4-35 °C, at pH 6.0-8.5 and could grow on chitin as the only carbon resource. Phylogenetic analysis, based on the 16S rRNA gene sequence, showed that strain NC1253T represented a novel bacterial genus within the family Ruminococcaceae. Strain NC1253T has less than 91.0 % similarity with other type strains, such as Harryflintia acetispora V20-281aT (90...

Many orthopedic articles describe advances in surgical techniques and implants used in pediatric scoliosis surgery. However, even though postoperative spine imaging constitutes a large portion of outpatient musculoskeletal pediatric radiology, few, if any, radiology articles discuss this topic. There has been interval advancement over the last decades of the orthopedic procedures used in the treatment of spinal scoliosis in adolescents with idiopathic scoliosis. The goal of treatment in these patients is to stop the progression of the curve by blocking the spinal growth and correcting the deformity as much as possible...

STUDY DESIGN: Cross-sectional study. OBJECTIVE: Assess the psychosocial status of children with early-onset scoliosis (EOS) undergoing multiple procedures and evaluate associations with other variables. SUMMARY OF BACKGROUND DATA: EOS may require repetitive surgical procedures to control deformity and preserve growth. These procedures impact patients' psychosocial status because of the repetitive surgeries. METHODS: EOS patients 6-18 years, undergoing traditional growing rod treatment with more than 5 surgical procedures, and neurologically/mentally intact were included...

Several strains of sulfate-reducing bacteria were isolated from marine sediments recovered from Hann Bay (Senegal). All were related to members of the genus Desulfovibrio. A strictly anaerobic, mesophilic and moderately halophilic strain designated BLaC1T was further characterized. Cells of strain BLaC1T stained Gram-negative and were 0.5 µm wide and 2-4 µm long, motile, rod-shaped and non-spore-forming. The four major fatty acids were anteiso-C15 : 0, iso-C15 : 0, iso-C17 : 0 and anteiso-C17 : 0...

BACKGROUND CONTEXT: In several studies, vertical expandable prosthetic titanium rib (VEPTR) implants have shown good scoliosis control in children with the longest reported follow-up (f/u) of 3.6 years. For growing rods, recent studies suggest a decreased efficiency of correction starting just after that time. To our knowledge, no long-term results of children with VEPTR treatment are available. PURPOSE: To evaluate spinal deformity in scoliotic children and to investigate correction potential of VEPTR implants at several time points of treatment, particularly after long-term f/u...
