Nurses' Work Concerns and Disenchantment During the COVID-19 Pandemic: Machine Learning Analysis of Web-Based Discussions.

Background: Web-based forums provide a space for communities of interest to exchange ideas and experiences. Nurse professionals used these forums during the COVID-19 pandemic to share their experiences and concerns.

Objective: The objective of this study was to examine the nurse-generated content to capture the evolution of nurses' work concerns during the COVID-19 pandemic.

Closer to a compromise on the direction of environmental research.

The Committee for the National Institute for the Environment (CNIE) was created in 1990 "to improve the scientific basis for making decisions on environmental issues," possibly through the establishment of a separate institute devoted to the environmental sciences. But while the goals proposed for the National Institute for the Environment were universally applauded, Congress was averse to adding a new agency to the federal bureaucracy. Recently, a compromise plan has been proposed that could expand the science base without having to create a new agency.

Peer reviewed: creating multidisciplinary research opportunities.

A unifying framework model helps researchers to address the complexities of environmental problems.

Anesthetic potency of remifentanil in dogs.

Background: Remifentanil is an opioid that is rapidly inactivated by esterases in blood and tissues. This study examined the anesthetic potency and efficacy of remifentanil in terms of its reduction of enflurane minimum alveolar concentration (MAC) in dogs.

Methods: Twenty-five dogs were anesthetized with enflurane.

The use of sodium dodecyl sulfate-polyacrylamide gel electrophoresis to detect renal damage in Sprague-Dawley rats treated with gentamicin sulfate.

Renal toxicity is a common manifestation to the exposure of laboratory animals and humans to a wide range of xenobiotics. Traditional methods for evaluating renal damage by clinical chemistry such as blood urea nitrogen (BUN) and serum creatinine are not sensitive to early, mild changes. The use of sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) to measure the molecular weight spectrum of urinary proteins allows for an evaluation of the functional changes associated with renal damage.

The propionic acids. Gastrointestinal toxicity in various species.

The propionic acids represent the largest chemical class of nonsteroidal anti-inflammatory agents (NSAID). Several of them are widely used, both in the United States and internationally. This paper discusses observations made on fenoprofen, flurbiprofen, ibuprofen and naproxen.
