In Bacillus subtilis, carbon catabolite repression (CCR) of many genes is mediated at cis-acting carbon repression elements (cre) by the catabolite repressor protein CcpA. Mutations in transcription-repair coupling factor (mfd) partially relieve CCR at cre sites located downstream of transcriptional start sites by abolishing the Mfd-mediated displacement of RNA polymerase stalled at cre sites w...

Objectives: To determine the effect of calorie delivery on hospital mortality among critically ill adults receiving enteral nutrition (EN). Secondary outcomes included the effect of calorie delivery on intensive care unit and hospital length of stay (LOS), duration of mechanical ventilation (MV) and incidence of new-onset pneumonia. Methods: We identifi ed randomised clinical trials of EN, with...

We discuss how the canonical commutation relations must be modified in order to make appropriate numerical models of quantum systems. The C∗-algebras associated with the discretized CCRs are the non-commutative spheres of Bratteli, Elliott, Evans and Kishimoto. 1991 Mathematics Subject Classification. Primary 46L40; Secondary 81E05.

PURPOSE The Canadian C-spine (cervical spine) Rule (CCR) and the National Emergency X-Radiography Utilization Low-Risk Criteria (NLC) are criteria designed to guide C-spine radiography in trauma patients. It is unclear how these 2 rules compare with young children. METHODS This study retrospectively examined case-matched trauma patients 10 years or younger. Two cohorts were identified-cohort ...

BACKGROUND MRI is an important clinical tool for diagnosing dementia-like diseases such as Frontemporal Dementia (FTD). However there is a need to develop more accurate and standardized MRI analysis methods. OBJECTIVE To compare FTD with Alzheimer's Disease (AD) and Mild Cognitive Impairment (MCI) with three automatic MRI analysis methods - Hippocampal Volumetry (HV), Tensor-based Morphometry...

Objetivo: Revisar a literatura com o objetivo de identificar as principais complicações do câncer colorretal (CCR). Revisão Bibliográfica: O CCR é um tumor maligno responsável por ser terceira causa morte associada ao no Brasil. pode classificado como familiar ou esporádico, sendo último, mais predominante. Devido diagnóstico tardio, déficit rastreio adequado, há aumento incidência complicações...

in this research, efficiency of iranian forest and rangeland decision making unit was assessed using non-parametric method. inputs and outputs determined by field research and with applying a delphi method the final input and output variables selected. forty five wood-producing units (forestry plans) in three northern iranian province were studied using data envelopment analysis. the efficiency...
