Wildfire smoke (WFS) is an urgent and rapidly growing threat to global health. Aside from obvious threats to pulmonary function, increases in cardiac abnormalities or myocardial infarction have been documented during WF season, but little is known about the effects of WFS on cardiovascular health. We investigated the effect of nonoccupational WFS exposure on cardiovascular and pulmonary function at rest and during graded handgrip exercise through a case series of young, healthy adults (n = 4, 25 ± 6 years) assessed after ≥3 days of bad or good air quality.

- The study aims to understand whether the NIRS-vascular occlusion test (NIRS-VOT) shows differences in muscle metabolism based on sex and limb while also examining the impact of dietary capsaicin on metabolic estimates during the test.
- Results showed significant differences in tissue desaturation rates (DeO) between limbs, with the quadriceps showing higher rates than the forearm, and between sexes, with women having higher DeO than men.
- Capsaicin, while tested for its effects on muscle metabolism, did not produce clear changes, but interactions involving limb type, sex, and capsaicin were noted.
Article Synopsis
- Watching news can make people feel stressed, while Bob Ross's peaceful art can help people feel relaxed.
- A study tested if watching Bob Ross would make people feel better and help their heart health compared to watching the news.
- The results showed that watching Bob Ross improved mood by reducing feelings like anxiety and depression, but it didn't change heart health much.
Background: This paper aims to investigate the correlations between the concentrations of nine heavy metals in moss and atmospheric deposition within ecological land classes covering Europe. Additionally, it is examined to what extent the statistical relations are affected by the land use around the moss sampling sites. Based on moss data collected in 2010/2011 throughout Europe and data on total atmospheric deposition modelled by two chemical transport models (EMEP MSC-E, LOTOS-EUROS), correlation coefficients between concentrations of heavy metals in moss and in modelled atmospheric deposition were specified for spatial subsamples defined by ecological land classes of Europe (ELCE) as a spatial reference system.

Gold nanoparticles can be biofunctionalized to bind to specific cells, and stimulated for local temperature increase due to plasmon resonance, causing a rapid change of the optical phase. These phase changes can be recorded by interferometric phase microscopy and analyzed to form an image of the binding sites of the nanoparticles in the cells, gaining molecular specificity.
