While some evidence of an effect of radiation exposure on respiratory disease at low dose levels has now emerged, there is heterogeneity in the risks between different studies and countries. In this paper, we aim to show the effect of radiation on three different sub-types of respiratory disease mortality through the analysis of the NRRW cohort in UK. The NRRW cohort consisted of 174,541 radiation workers. Doses to the surface of the body were monitored...

Epidemiological and interventional studies have been rarely conducted among those with positive interferon-γ release assay (IGRA) results and radiologically inactive tuberculosis (TB) lesions on chest radiograph. This study aimed to estimate the effectiveness and safety of a 6-week twice-weekly regimen (rifapentine plus isoniazid) among this key population in rural China. First, chest digital radiography was conducted to screen individuals with inactive TB lesions. Then, the identified participants were further evaluated and eligible participants with IGRA...

Two new sesquiterpenes (1–2) and six known analogues (3–8) were isolated from the branches and leaves of Xylopia vielana Pierre. The structures of the new compounds were identified by analyzing 1 D and 2 D NMR data and HRESIMS data, combined with induced and calculated circular dichroism experiments. In addition, compounds 1–4, 7 and 8 showed notable nitric oxide (NO) inhibitory effects (IC50 < 10 μM) on the model of the lipopolysaccharide (LPS)-activated RAW 264.7...
