Alternative splicing (AS) is an important post-transcriptional regulatory mechanism that can increase protein diversity and affect mRNA stability. Different types of AS have been observed; these include exon skipping, alternative donor or acceptor site and intron retention. In humans, exon skipping is the most common type while intron retention is rare. In contrast, in Arabidopsis, intron reten...

Introduction Perfusion process involves retention of the cells inside the bioreactor while simultaneously removing spent medium and adding fresh medium continuously. The flow rate of addition of fresh and removal of spent medium are generally kept the same (perfusion rate) to maintain the culture volume inside the bioreactor. Cell retention is possible with many devices but the reliability and ...

OBJECTIVE Five NICUs that participate in the Vermont Oxford Network's Neonatal Intensive Care Quality Improvement Collaborative 2002 attempted to identify potentially better practices that would have a directly impact on nurse recruitment and retention. The group identified nurse recruitment and retention as an important initiative for many hospitals that face a nursing shortage. METHODS The ...

Soil and aquifer materials have a finite capacity for colloid retention. Blocking of the limited number of available retention sites further decreases the rate of retention with time and enhances risks (e.g., pathogens or colloid-associated contaminants) or benefits (e.g., remediation by microorganisms or nanoparticles) of colloid migration. Our objective was to use a straightforward procedure,...

Different mechanisms will contribute to tritium retention in ITER, amongst which co-deposition with materials from the plasma-facing components may be the main contributor. A systematic study of the influence of the deposition conditions (substrate temperature, deposition rate, energy of the incident particles) on the deuterium retention in co-deposited beryllium layers has been carried out in ...

Purpose In this experiment you will examine the effect of temperature on retention in isothermal gas chromatography, and use this information to determine the heat of solution of the solute in the stationary phase and to determine the temperature for optimum retention. You will also examine the effect of flow rate on efficiency and construct a van Deemter plot, and determine the flow rate for o...

OBJECTIVES To investigate mortality in men admitted to hospital with acute urinary retention and to report on the effects of comorbidity on mortality. DESIGN Analysis of the hospital episode statistics database linked to the mortality database of the Office for National Statistics. SETTING NHS hospital trusts in England, 1998-2005. PARTICIPANTS All men aged over 45 who were admitted to NH...

BACKGROUND The retention rate or the percentage of women who return to screening within 30 months of a previous screening is an important measure of screening success and the acceptability of the screening program to women. The objective of this study was to investigate variables associated with the retention of women 50 to 68 years of age who were screened by the Manitoba Breast Screening Prog...

OBJECTIVE To evaluate the risk factors for postoperative urinary retention in women who underwent vaginal hysterectomy for symptomatic pelvic organ prolapse. METHODS The medical records of 221 women who underwent vaginal hysterectomy with anterior and posterior colporrhapy were reviewed. Urinary retention after catheter removal was defined as the presence of at least one of the following thre...
