Evacuation of wounded with intracranial injury to a hospital without neurosurgical service versus primary evacuation to a level I trauma centre.

Background: Several studies have shown that delay in neurosurgical intervention worsens the neurologic outcome. However, rapid evacuation of wounded sustaining intracranial injury (ICI) to the nearest hospital may have some advantages, as the nearest hospital ER may be a better environment to prevent a secondary brain injury than the ambulance. Also, evacuation to a referral centre of all the wounded suspected in the field to have ICI will result in high rates of over triage.

Structure-specificity relationships of an intracellular xylanase from Geobacillus stearothermophilus.

Geobacillus stearothermophilus T-6 is a thermophilic Gram-positive bacterium that produces two selective family 10 xylanases which both take part in the complete degradation and utilization of the xylan polymer. The two xylanases exhibit significantly different substrate specificities. While the extracellular xylanase (XT6; MW 43.

Crystallization and preliminary X-ray analysis of the thermostable alkaline-tolerant xylanase from Bacillus stearothermophilus T-6.

The extracellular thermostable xylanase (XT-6) produced by the thermophilic bacterium Bacillus stearothermophilus T-6 was shown to bleach pulp optimally at pH 9 and 338 K, and was successfully used in a large-scale biobleaching mill trial. The xylanase gene was cloned and sequenced. The mature enzyme consists of 379 amino acids with a calculated molecular weight of 43,808 and pI of 9.

Structure determination of the extracellular xylanase from Geobacillus stearothermophilus by selenomethionyl MAD phasing.

Xylanases are hemicellulases that hydrolyze the internal beta-1,4-glycoside bonds of xylan. The extracellular thermostable endo-1,4-beta-xylanase (EC 3.2.
