Mechanistic Studies of Alkyl Chloride Acetoxylation by Pt-Sb Complexes.

The bis-acetate complexes (SbQ)Pt(OAc) () and (SbQPh)Pt(OAc) () (Q = 8-quinolinyl) were used to study C-Cl acetoxylation of 1,2-dichloroethane (DCE) to generate 2-chloroethyl acetate and the complexes (SbQ)PtCl () and (SbQPh)PtCl (), respectively. The first acetoxylation step produced the intermediates (SbQ)Pt(Cl)(OAc) () and (SbQPh)Pt(Cl)(OAc) (). The reaction was studied using pseudo first order kinetics (excess DCE) in order to compare the rates of reaction of and , which revealed that = 2.

Polymer Binder Blends Stabilize Alkaline Hydrogen Evolution by Heterogenized Molecular Phen-Based Cobalt Electrocatalysts through Coordination and Environmental Control.

With the increase in greenhouse gas emissions and their detrimental effect on the environment, there is a push to develop a renewable way to produce H, a fuel source that has nonharmful byproducts, unlike traditional methods of energy production. Alkaline water electrolysis has seen increasing focus as a viable way to produce H, but efficient and stable electrocatalysts are required to facilitate this process. Here, a heterogenized Co(II) phenanthroline-based complex for the production of H from alkaline water is disclosed.

Investigating the Mechanism of Conditioning Versus Postoperative Electrical Stimulation to Enhance Nerve Regeneration: One Therapy, Two Distinct Effects.

Regeneration after peripheral nerve injury is often insufficient for functional recovery. Postoperative electrical stimulation (PES) following injury and repair significantly improves clinical outcomes; recently, conditioning electrical stimulation (CES), delivered before nerve injury, has been introduced as a candidate for clinical translation. PES accelerates the crossing of regenerating axons across the injury site, whereas CES accelerates the intrinsic rate of axonal regeneration; thus, it is likely that their mechanisms are distinct.

Variations in Prescribing Rates of End-of-Life Medications Among Long-Term Care Residents in Alberta Compared with Ontario-a Retrospective Cohort Study.

Background: Prescribing rates for subcutaneous medications may be an indicator of quality of end-of-life care in long-term care (LTC). It is not known if this system level measure is valid across jurisdictions. We compared prescribing rates of medications used for end-of-life symptom relief among LTC residents in Alberta and Ontario.

Laboratory Test Use and Values in the Last Year of Life-a Matched Cohort Design.

Background: As individuals approach death, they experience declines in their cognitive, physical, motor, sensory, physiologic, and psychosocial functions. In this exploratory study we examined individuals' physiologic changes in the last year of life by examining laboratory tests commonly used in clinical practice.

Methods: Using health administrative datasets, we conducted an observational matched cohort study to assess laboratory test use and values over a decedent's last 12 months and a matched observation window for non-decedents.
