A novel strain, 1433(T), was isolated from leaves of Chinese red pepper (Huajiao, Zanthoxylum bungeanum Maxim) collected from Gansu province in northwestern China, and was characterised by a polyphasic approach. Cells of strain 1433(T) were observed to be Gram-stain positive, aerobic, asporogenous, rod shaped, motile and to have peritrichous flagella. The strain was observed to grow at a range of temperatures and pH, 4-45 °C (optimum 28-32 °C) and 6.0-10.0 (optimum pH 6.0-7.0), respectively. Growth was found to occur in the presence of 0-7% (w/v) NaCl [optimum 0-3% (w/v)]...

Thin, flexible silicon crystals are starting up applications such as light-weighted flexible solar cells, SOI, flexible IC chips, 3D ICs imagers and 3D CMOS imagers on the demand of high performance with low cost. Kerfless wafering technology by direct conversion of source gases into mono-crystalline wafers on reusable substrates is highly cost-effective and feedstock-effective route to cheap wafers with the thickness down to several microns. Here we show a prototype for direct conversion of silicon source gases to wafers by using the substrate with protruded seeds...

Bacillus subtilis is the best described member of the Gram positive bacteria. It is a typical rod shaped bacterium and grows by elongation in its long axis, before dividing at mid cell to generate two similar daughter cells. B. subtilis is a particularly interesting model for cell cycle studies because it also carries out a modified, asymmetrical division during endospore formation, which can be simply induced by starvation. Cell growth occurs strictly by elongation of the rod, which maintains a constant diameter at all growth rates...

BACKGROUND: In many countries, the oldest old (those aged 85 years and older) are now the fastest growing proportion of the total population. This oldest population will increasingly be living with the clinical condition of frailty. Frailty syndromes negatively impact on the person as they do the healthcare systems supporting them. Within healthcare literature "loss of confidence" is occasionally connected to older people living with frailty, but ambiguously described. Understanding the concept of confidence within the context of frailty could inform interventions to meet this growing challenge...

PURPOSE: To compare the yearly cost involved per patient in the use of magnetically controlled growing rod (MCGR) and traditional growing rods (TGRs) in the treatment of early onset scoliosis (EOS) and to assess the overall cost burden of MCGR with reference to patient and health-care infrastructure. METHODS: For a hypothetical case of a 5-year-old girl with a diagnosis of EOS, a decision-tree model using TreeAge Software was developed to simulate annual health state transitions and compare the 8-year accumulative direct, indirect, and total cost among the four groups: (1) dual MCGRs with exchange every 2 years, (2) dual MCGRs with exchange every 3 years, (3) TGR with surgical distraction every year, and (4) TGR with surgical distraction every 6 months...

The notochord is a rod-like embryological structure, which plays a vital role in the development of the vertebrate. Though embryological, remnants of this structure have been observed in the nucleus pulposus of the intervertebral discs of normal adults. Pathologically, these remnants can give rise to slow-growing and recurrent notochord-derived tumors called chordomas. Using standard search engines, the literature was reviewed regarding the anatomy, embryology, molecular development, and pathology of the human notochord...

Treatment paradigms for Early Onset Scoliosis have changed from fusion to fusionless methods as the harmful effects of early fusion on the growing spine and thorax were realized. Magnetic rods are a recent addition to fusionless technology for controlling scoliosis in a growing spine. The clinical evidence base on magnet driven growth rods (MDGR) has accumulated over the last 4 years. It has implications for reduction in the number of repeat surgeries required with similar complications as the traditional growth rods (TGR) and at a higher initial cost...

A novel facultatively anaerobic bacterium, designated strain LAM-WHM-D11(T), was isolated from a frozen soil sample of China. Cells of strain LAM-WHM-D11(T) were observed to be Gram-stain negative, non-motile and rod-shaped. Colonies were yellowish, and circular with convex shape. Strain LAM-WHM-D11(T) was found to be able to grow at 4-40 °C (optimum 15 °C), pH 7.5-2.0 (optimum 9.5) and 0-2.5% NaCl (w/v) (optimum 1.5%). The 16S rRNA gene sequence similarity analysis showed that strain LAM-WHM-D11(T) is closely related to Arenimonas metalli CF5-1(T) (98...

STUDY DESIGN: Experimental animal study. OBJECTIVE: To investigate the interaction between magnetically controlled growing rods (MCGRs) and magnetic resonance imaging (MRI). SUMMARY OF BACKGROUND DATA: Growing rod treatment through serial operations results in adverse effects on the patient and high treatment costs. MCGRs can be lengthened noninvasively in an outpatient setting and with lower treatment costs. When MRI investigation is required, the interaction between MCGRs and MRI is an issue of concern in patients with MCGRs...

Almost half of growing rod (GR) patients that undergo final fusion (FF) have an extension of instrumented levels. The purpose of this study was to review sagittal plane radiographic parameters of patients with distal extension of instrumented levels at FF to those whose levels remained the same. Radiographs were assessed preoperatively, after GR insertion/first lengthening, following GR treatment before FFs, and after FF. Measurements included sagittal balance, lumbar lordosis, thoracic kyphosis, and distal junction angle (DJA)...
