Summary: This study investigated the efficient delivery of reactive and toxic gaseous reagents in organic reactions using metal-organic frameworks (MOFs). It was found that MOFs can serve as both gas cargo vehicles and catalysts, leading to high product yields. Moreover, the MOFs can be recycled without sacrificing product yield and crystallinity, indicating the potential of developing multifunctional MOF-based reagent-catalyst cargo vessels as an attractive alternative to toxic pure gases or gas generators.

Summary: Diabetic nephropathy (DN) is still the main cause of morbidity and mortality in diabetes patients. Gasotransmitters, including nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S), play a vital role in the development and progression of DN. Aberrant levels of gasotransmitters have been observed in patients with diabetes, and gasotransmitter donors show potential in ameliorating diabetic renal dysfunction. This review provides an overview of the physiological relevance of gasotransmitters and their interaction with other factors in the severity modulation of DN, highlighting the possible therapeutic interventions.

Summary: Gasotransmitters are gaseous molecules synthesized within the body that play roles in various physiological and pathological processes at the cellular level. Long-term exposure to restraint stress has been shown to negatively impact male reproductive functions in rats, with changes in hormone levels and alterations in the expression of gasotransmitter producing enzymes in the hypothalamus and testes.

Summary: This article discusses the roles of diatomic molecules O-2, NO, and CO in biology, as well as the sensing proteins developed by nature to perceive and respond to changes in their levels. It focuses on heme-based proteins and their advanced structural and electronic adjustments for sensing, along with their possible role in redox sensing. Finally, the potential therapeutic interventions on these gas sensors and the design of small diatomic molecules for medical treatments are highlighted.

Summary: Although nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S) have long been considered as gas pollutants, they are actually endogenous gaseous signaling molecules (GSMs) with important signaling functions and medical applications. Stimuli-responsive nanocarriers have been developed to achieve controlled delivery of GSMs and reduce side effects, with ultrasound being an attractive modality for tracking drug carriers, triggering drug release, and improving drug deposition. This minireview summarizes recent advancements in designing ultrasound-responsive nanocarriers for controlled delivery of GSMs and their biomedical applications. This emerging research direction enables targeted delivery of GSMs to deep tissues, and the combination with ultrasound imaging techniques offers potential for new theranostic platforms.

Summary: The major toxic effects of acute carbon monoxide poisoning are caused by increased reactive oxygen species and reactive nitrogen species, resulting in oxidative stress. This study aims to describe the deregulation of NO and H2S signaling pathways during CO poisoning and their interaction with CO signaling pathways, which contribute to cell injury.

Summary: In this study, the researchers compared generalized additive models and segmented regression models to determine the reference equations for pulmonary diffusing capacity for carbon monoxide and nitric oxide. The results showed that segmented linear regression can be used as an alternative to GAMLSS, especially when the predictive accuracy is similar between the two models. Additionally, the equipment used for measurement also had an impact on the results.

Summary: This study examined lung function in Hispanic subjects recovering from mild COVID-19. It found that one-third of patients had impaired pulmonary diffusing capacity for carbon monoxide (DLCO) and one-fifth had a restrictive spirometric pattern. Factors such as age, spirometric pattern, and symptoms were associated with impaired DLCO.

Summary: The objective of this study was to determine the stability of blood gases under different storage conditions using survival analyses. The results showed that pCO(2) and pH in blood samples remained stable for 60 minutes at room temperature and 3 hours in slushed ice. However, storing samples in slushed ice reduced the stability time for pO(2), especially when the baseline pO(2) was ≥60 mmHg. In conclusion, according to RCPA guidelines, blood gas and CO-oximetry panels can be stored for up to 40 minutes at room temperature.

Summary: Non-alcoholic fatty liver disease (NAFLD) is closely related to bile acid and gut microbiota disorders. Exercise plays an important role in maintaining the homeostasis of the enterohepatic circulation and the health of the host gut microbiota by regulating the composition and function of the bile acid pool in the enterohepatic axis. Exercise has been recommended as a first-line intervention for NAFLD, and regulating bile acids through exercise may be a promising treatment strategy.
