Mitigation of Chemical Reporting Liabilities through Systematic Modernization of Chemical Hazard and Safety Data Management Systems.

In the United States alone, approximately 2 billion tons of hazardous material products are manufactured each year for both household and industrial applications and contribute to thousands of worker chemical exposures with as many as 50,000 deaths from prolonged exposure each year. The potential hazards and impacts of these chemicals for human health and the environment are primarily communicated to the public through Safety Data Sheets (SDSs) from the chemical vendors or distributors. These documents provide a standardized approach for how and what information is provided to product users to assist them with assessment of precautionary measures, hazard mitigation, emergency response or cleanup procedures, and environmental, health, and safety (EHS) management.

Blockchain technology in the smart city: a bibliometric review.

Blockchain can function as a foundational technology with numerous applications in smart cities. The objective of this paper is twofold. First, it provides a detailed overview of the extant literature on blockchain applications in smart cities; second, it reveals the trends and suggests future research directions for scholars who wish to contribute to this rapidly growing field.

Osteoprotegerin is an effective countermeasure for spaceflight-induced bone loss in mice.

Bone loss associated with microgravity exposure poses a significant barrier to long-duration spaceflight. Osteoprotegerin-Fc (OPG-Fc) is a receptor activator of nuclear factor kappa-B ligand (RANKL) inhibitor that causes sustained inhibition of bone resorption after a single subcutaneous injection. We tested the ability of OPG-Fc to preserve bone mass during 12 days of spaceflight (SF).

In vivo measurement of hindlimb neuromuscular function in mice.

Introduction: In vitro or in situ methods to assess neuromuscular performance in rodents are invasive and inadequate to fully assess large hindlimb muscles.

Methods: An in vivo hindlimb exertion force test (HEFT) was developed to quantify muscle function peak force (PF), peak rate of force development (PRFD), and short- and long-latency reaction times (SLRT and LLRT, respectively) in C57BL/6J mice.

Results: PF did not change with one- and three-times-per-week repeated HEFT trials, demonstrating assessment reproducibility.
