Toxicological approach to setting spacecraft maximum allowable concentrations for carbon monoxide [PDF]

The Spacecraft Maximum Allowable Concentrations (SMACs) are exposure limits for airborne chemicals used by NASA in spacecraft. The aim of these SMACs is to protect the spacecrew against adverse health effects and performance decrements that would ...

A Dual‐Targeting Biomimetic Nanoplatform Integrates SDT/CDT/Gas Therapy to Boost Synergistic Ferroptosis for Orthotopic Hepatocellular Carcinoma Therapy

Advanced Science, Volume 12, Issue 8, February 24, 2025.
This study reports an HCC‐targeted nanoplatform that combines FeMoO4 nanoenzyme, CO‐releasing compounds, and SP94‐modified macrophage membrane. This platform improves ferroptosis‐driven multimodal treatment by producing oxygen, depleting glutathione, and creating hydroxyl radicals.

Simplified determination of carboxyhemoglobin.

Clinical Chemistry, 1984
Abstract This spectrophotometric method for estimating carboxyhemoglobin is based on the production of a two-pigment mixture by reducing oxyhemoglobin and methemoglobin with sodium hydrosulfite . Absorbances of the pigment are measured at 420 and 432 nm. Protecting the solutions against exposure to air is unnecessary.

Cardiorespiratory Fitness Improvements Following Low‐Frequency Training Are Not Inferior to High‐Frequency Training Matched for Intensity and Volume

Scandinavian Journal of Medicine &Science in Sports, Volume 35, Issue 2, February 2025.
ABSTRACT Epidemiological evidence suggests low‐frequency physical activity provides health benefits, but the physiological impacts of weekly training frequency are understudied. We investigated whether “Weekend Warrior” (WW) training was inferior to traditional, high‐frequency (HF) training for improving maximal oxygen uptake (V̇O2max).
