Background: Perineal trauma involving the anal sphincter is an important complication of vaginal delivery. Prediction of anal sphincter injuries may improve the prevention of anal sphincter injuries. Our aim was to construct a risk scoring model to assist in both prediction and prevention of Obstetric Anal Sphincter Injuries (OASIs). We carried out an analysis of factors involved with OASIs, an...

OBJECTIVES To investigate the association between the geometrical properties of episiotomy and obstetric anal sphincter injuries (OASIS) because episiotomies angled at 40-60° are associated with fewer OASIS than episiotomies with more acute angles. DESIGN Case-control study. SETTING University Hospital of North Norway, Tromsø and Nordland Hospital, Bodø, Norway. SAMPLE Seventy-four women ...

The conversion of virgin desert into oasis farmland creates two contrasting types of land-cover. During oasis formation with irrigation and fertilizer application, however, the changes in the soil microbial population, which play critical roles in the ecosystem, remain poorly understood. We applied high-throughput pyrosequencing to investigate bacterial and archaeal communities throughout the p...

The WS-BPEL 2.0 specification [WS-BPEL 2.0] provides a language for formally describing business processes and business interaction protocols. WS-BPEL was designed to extend the Web Services interaction model to support business transactions. The WS-BPEL Primer is a non-normative document intended to provide an easy to read explanation of the WS-BPEL 2.0 specification. The goal of this document...

An inventory was carried out at five stations in the oasis of Ziban, an oasis that is characterized by its high-quality dates, in order to study the relationships between the oasis ecosystem and its insect fauna. Specimens were sampled using pitfall traps containing ethylene glycol as a preservative. In total, 115 arthropod species were collected during 5 months of survey. These species belonge...

A significant gap exists between genetics-based investigations of polyketide synthase (PKS) and nonribosomal peptide synthetase (NRPS) biosynthetic pathways and our understanding of their regulation, interaction, and activity in living systems. To help bridge this gap, here we present an orthogonal active site identification system (OASIS) for the proteomic identification and analysis of PKS/NR...

OASIS is a Language for the Specification of Object Oriented Conceptual Models. Object Petri Nets (OPNs) support a full integration of object-oriented concepts into Petri Nets. We propose a way to represent objectoriented concepts used in the OASIS language with OPNs as a suitable semantic model for validating software specifications. We have developed a Basic Execution Model for OASIS Specific...

Magnetic resonance imaging (MRI) can be used to detect lesions in the brains of multiple sclerosis (MS) patients and is essential for diagnosing the disease and monitoring its progression. In practice, lesion load is often quantified by either manual or semi-automated segmentation of MRI, which is time-consuming, costly, and associated with large inter- and intra-observer variability. We propos...

Distinguished Contributors The "OASIS Distinguished Contributor" designation is awarded to a select group of OASIS members who have made significant contributions to the advancement of open standards. We gratefully acknowledge these outstanding individuals for their impact on the global information society.

OBJECTIVE To review the evidence relating to obstetrical anal sphincter injuries (OASIS) with respect to diagnosis, repair techniques and outcomes. To formulate recommendations as to patient counselling regarding route of delivery for subsequent pregnancy after OASIS. OPTIONS Obstetrical care providers caring for women with OASIS have the option of repairing the anal sphincter using end-to-en...
