OBJECTIVE To review the clinical characteristics and outcomes of critically ill obstetrical patients and to determine the outcome predictability using the Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system. METHODS A retrospective data collection of all obstetrical patients (n = 49) admitted for more than 24 hours to the Intensive(More)
Numerous steps are required to prepare a sequencing library for serial analysis of gene expression (or SAGE) from an original mRNA sample. The presence of inefficiencies, however, can lead to a cumulative loss of sample during processing which can yield a library of short sequence tags (SSTs) that represents only a minute fraction of the original starting(More)
The switch from budding to filamentous growth is a key aspect of invasive growth and virulence for the fungal phytopathogen Ustilago maydis. The cyclic AMP (cAMP) signaling pathway regulates dimorphism in U. maydis, as demonstrated by the phenotypes of mutants with defects in protein kinase A (PKA). Specifically, a mutant lacking the regulatory subunit of(More)
The ability of Serial Analysis of Gene Expression (SAGE) to provide a quantitative picture of global gene expression relies not only on the depth and accuracy of sequencing into the SAGE library, but also on the efficiency of each step required to generate the SAGE library from the starting mRNA material. The first critical step is the ligation of adaptors(More)
Methods for the extraction of nucleic acids are straightforward in instances where there is ample nucleic acid mass in the sample and contamination is minimal. However, applications in areas such as metagenomics, life science research, clinical research, and forensics, that are limited by smaller amounts of starting materials or more dilute samples, require(More)
