Intensified Continuous Flow Process for the Scalable Production of Bio-Based Glycerol Carbonate.

A subtle combination of fundamental and applied organic chemistry toward process intensification is demonstrated for the large-scale production of bio-based glycerol carbonate under flow conditions. The direct carbonation of bio-based glycidol with CO is successfully carried out under intensified flow conditions, with Barton's base as a potent homogeneous organocatalyst. Process metrics for the CO coupling step (for the upstream production, output: 3.

Perspectives for the Upgrading of Bio-Based Vicinal Diols within the Developing European Bioeconomy.

The previous decade has witnessed a drastic increase of European incentives aimed at pushing forward the transition from an exclusively petro-based economy toward a strong and homogeneous bio-based economy. Since 2012, numerous programs have been developed to stimulate and promote research and innovation relying on sustainable and renewable resources. Terrestrial biomass is a virtually infinite reservoir of biomacromolecules, the biorefining of which provides platform molecules of low complexity yet with tremendous industrial potential.

Measuring colposcopy quality in Canada: development of population-based indicators.

Background: Colposcopy is a key part of cervical cancer control. As cervical cancer screening and prevention strategies evolve, monitoring colposcopy performance will become even more critical. In the present paper, we describe population-based colposcopy quality indicators that are recommended for ongoing measurement by cervical cancer screening programs in Canada.

Predictors of Residual Disease After Breast Conservation Surgery.

Introduction: Breast-conserving therapy is the standard of care for early-stage breast cancer. In the era of multimodality therapy, the debate on the value of revision surgery for compromised margins continues, and high re-excision rates persist despite updated guidelines. Our study sought to identify the local re-excision rate for compromised margins after lumpectomy, and identify predictors of residual disease at re-excision.

Posttraumatic stress disorder among women receiving prenatal care at three federally qualified health care centers.

This study assessed the prevalence and interrelationships of posttraumatic stress disorder (PTSD), antecedent trauma, and psychosocial risk factors among pregnant women served at three urban Federally Qualified Health Care Centers. This analysis was part of a validation study of the prenatal risk overview, a structured psychosocial risk screening interview. The study sample included 745 prenatal patients at three clinics who also were administered the major depression, PTSD, alcohol, and drug use modules of the Structured Clinical Interview for DSM-IV (SCID).
