The assessment of measurement uncertainty of an analytic method is a requirement for forensic toxicologists and drug chemists. There are two main methods for estimating measurement uncertainty: the bottom-up and the top-down approaches. The bottom-up approach has been suggested in current practice guides including 'Guide to the Expression of Uncertainty in Measurement (GUM)' published by ISO, and a guide to 'Quantifying Uncertainty in Analytical Measurement' published by EURACHEM.

Precise prefractionation of proteome samples is a potent method for realizing in-depth analysis in top-down proteomics. PEPPI-MS (Passively Eluting Proteins from Polyacrylamide gels as Intact species for MS), a gel-based sample fractionation method, enables high-resolution proteome fractionation based on molecular weight by highly efficient extraction of proteins from polyacrylamide gels after SDS-PAGE separation. Thereafter it is essential to effectively remove contaminants such as CBB and SDS from the PEPPI fraction prior to mass spectrometry.

Introduction: Persistent post-endodontic pain following endodontic therapy is a rare but substantial clinical challenge. Mechanisms that mediate peripheral neuropathy and/or central sensitization likely play a pivotal role in its development and chronification. The objective of this case series is to describe a management plan for persistent post-endodontic pain and provide prescription guidelines using a standardized "Gabapentin Pyramid Protocol" for clinical practice.

Management of natural resources and environmental systems has often involved top-down approaches in which government agencies set and enforce regulations on extractive activities. More recently, market-driven approaches were introduced to incentivise producers to voluntarily engage in practices that align with management objectives and support regulations. For the first time, we compare government and voluntary approaches within fisheries management systems and quantify their relative influences on the sustainability status of fish populations.

This paper explores how small local health departments (LHDs) motivated staff members, communicated progress toward Public Health Accreditation Board accreditation or Pathways Recognition, and celebrated interim and final accreditation accomplishments. Qualitative key informant interviews were conducted with 22 employees and affiliates of 4 LHDs with jurisdiction populations <50 000. LHDs motivated staff through ownership, creative strategies to monitor and record progress, and meaningful no- or low-cost incentives.
